Spirometry has been used as a common diagnostic test in asthma. Most of the patients with a mild asthma have a FEV1 within normal range. Hence, other diagnostic methods are usually used. The aim of this study was to evaluate whether eosinophil Cationic Protein (ECP) could be an accurate diagnostic marker of mild asthma. In this study diagnosis of asthma was made according to internationally accepted criteria. Asthma severity was evaluated according to frequency of symptoms and FEV1.Adequate sputum samples were obtained in 50 untreated subjects. A control group of 12 normal subjects that showed PC20 more than 8 mg/dl was also examined. Sputum was induced by inhalation of hypertonic saline. Inflammatory cells in sputum smears were assessed semi-quantitatively. ECP and IgE concentrations, eosinophil (EO) percentage and ECP/EO ratio in serum and sputum were also determined. The results revealed that Cough and dyspnea were the most frequent clinical findings. Dyspnea and wheezing were the symptoms that correlated with staging of asthma. FEV1 was within normal range (more than 80% of predicted) in 22 (44%) subjects.Asthmatic patients showed significantly higher numbers of blood eosinophils (4.5+/- 3.1% vs. 1.2+/-0.2%, P=0.009), and higher levels of serum ECP than control group (3.1+/- 2.6 % and 22.6+/- 15.8 ng/ml, respectively). Sputum ECP level in asthmatics was significantly higher than non- asthmatics (55.3+/-29.8ng/mL vs. 25.0+/-24.7ng/mL, P=0.045). Regression analysis showed no significant correlation between spirometric parameters and biomarkers, the only exception was significant correlation between FEF(25-75) and serum ECP (r= 0.28, P 0.041). Regarding clinical symptoms, wheezing was significantly correlated with elevation of most of biomarkers. Since, serum and sputum ECP levels are elevated in untreated asthmatics, the ECP level could be used for accurate diagnosis of mild form of asthma in which spirometry is unremarkable.

- Abstract
Crimean-Congo haemorrhagic fever (CCHF) is a viral zoonotic disease with a high mortality rate in humans. The CCHF virus (CCHFV) is transmitted to humans through the bite of Ixodidticks or by contact with blood or tissues of infected livestock. In addition to zoonotic transmission, CCHFV can be spread from person to person and is one of the rare haemorrhagic fever viruses able to cause nosocomial outbreaks in hospitals. Crimean-Congo haemorrhagic fever is a public health problem in many regions of the world such as Eastern Europe, Asia, the Middle East and Africa. In addition to clinical symptoms, the diagnosis of CCHF is based on the use of serological tests for the detection of immunoglobulin M and immunoglobulin G antibodies and on the use of molecular tools such as RT-PCR. From 1970 to 1978, serological and epidemiological studies were performed in humans and in livestock of Iran. After two decades and observations of CCHF in some provinces of Iran, a CCHF surveillance and detection system was established in 1999, leading to a dramatically decreased mortality rate from 20 (year 2000) to 2 (year 2007).

Lai, J. K. L. and Meshkat, M.
- Abstract
A selective etching technique was used to reveal the χ-phase in a cast of Type 316 steel (18Cr-12Ni-2.5Mo). The volume fraction of the χ particles revealed by this technique was measured by using the Quantimet 720 image-analysing computer. The data obtained suggest that the precipitation of χ at 750°C and 815°C follows a law of the form V= f(t/τ), where Vis the volume fraction of χ formed in a time tand τ is a ‘characteristic time’ dependent upon temperature. The kinetics of M23C6precipitation in Type 316 steel at 625°C was also studied by a bulk extraction method. The data obtained obey the Johnson-Mehl equation with n≃ 1

Background: Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods: The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings: Globally, in 2019, the risk factors included in this analysis accounted for 4·45 million (95% uncertainty interval 4·01-4·94) deaths and 105 million (95·0-116) DALYs for both sexes combined, representing 44·4% (41·3-48·4) of all cancer deaths and 42·0% (39·1-45·6) of all DALYs. There were 2·88 million (2·60-3·18) risk-attributable cancer deaths in males (50·6% [47·8-54·1] of all male cancer deaths) and 1·58 million (1·36-1·84) risk-attributable cancer deaths in females (36·3% [32·5-41·3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20·4% (12·6-28·4) and DALYs by 16·8% (8·8-25·0), with the greatest percentage increase in metabolic risks (34·7% [27·9-42·8] and 33·3% [25·8-42·0]). Interpretation: The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden. We are grateful to the surveillance systems, including cancer registries, that generated and shared observed cancer burden data.

- Abstract
Background: Adherence to diet is effective for metabolic control in patients on hemodialysis. There are educational pamphlets or booklets to improve patients' knowledge about healthy diets. As video presentation is more desirable than the presentation of readable materials, we designed an educational video on healthy diets in renal failure patients who was played during several sessions of hemodialysis. We compared the effect of this modality on the knowledge, attitudes and metabolic control of the patients before and after the intervention., Methods: In this interventional study, all the patients who were referred to the hemodialysis ward at Ashrafi-Esfahani Medical Center (Tehran, Iran) between May 2018 and March 2019 were enrolled (N = 190). Totally, 130 patients had inclusion criteria. An educational video about a healthy diet was shown seven times (once a week in the first month, once every two weeks in the second month, and once in the third month) during hemodialysis for the patients. The nephrologist prepared a video in the form of a lecture with graphic images for 20 min based on the healthy nutrition of the Kidney Federation of Iran's Guide for hemodialysis patients. The questionnaire was completed in terms of awareness and attitudes, and blood and urine tests were performed at the 1st, 3rd, and 12th months. Serum parameters, including electrolytes, lipid profile, CBC-diff, dialysis efficacy (Kt/V), and the URR (urine filtration rate) were examined. Pre and post intervention values were compared via the statistical analysis performed using IBM SPSS. P-Value < 0.05 was significant., Results: The data of 128 people were analyzed at the end of the study. 55% of patients were 10-40 years old and 60% were male. 56% of patients were illiterate or had an elementary school education. The most common underlying diseases were hypertension and diabetes mellitus. Ten to 19% of participants had enough knowledge about the various components of a healthy diet for patients on hemodialysis. Approximately 25%, 14%, and 45% of the participants consumed a healthy diet for breakfast, lunch and dinner, respectively. A comparison of the mean values of the serum parameters before and after the intervention revealed significant changes in phosphorus, blood urea nitrogen, and hemoglobin with mean differences of -118.41 ± 22.84, 21.51 ± 10.38 (both P < 0.001), and 0.29 ± 1.18 (P = 0.044), respectively. The mean Kt/V was similar at all phases., Conclusion: The use of an educational video was effective for normalizing the metabolic parameters in patients under hemodialysis and can be an appropriate option, especially for illiterate patients., Trial Registration: IRCT2016082229481N1., (© 2024.

- Abstract
Background: Metabolic-associated fatty liver disease (MAFLD) is the most prevalent liver disease across the globe. One of the most effective treatments for this disease is weight loss. This study aimed to determine how metabolic and bariatric surgery (MBS) affects MAFLD sonographic grades., Methods: In 2021, a pre-post study was conducted on 73 patients who underwent MBS. The study collected demographic information and ultrasound grades of MAFLD before and after MBS., Results: A total of 73 patients underwent MBS, with 58 females and 15 males. The patients had a mean age of 39.8 ± 8.88 years and a mean BMI of 42.12 ± 5.98 kg/m
2 . Of these patients, 53 (72.6%) underwent SG, while 20 (27.4%) underwent RYGB. The preoperative BMI for females and males decreased significantly at the 12-month follow-up (P = 0.0001). However, males experienced more prominent weight changes (P = 0.009), but there was no statistically significant difference in fatty liver grade changes after MBS between males and females (P = 0.056), which suggests that the effect of MBS on fatty liver grades is not gender-specific. There was a significant reduction in BMI and fatty liver grade for patients under and over 40 years old after surgery (P = 0.0001). However, there was no statistically significant difference in fatty liver grade and BMI changes after MBS between the two age groups. RYGB was found to be more effective than SG in reducing fatty liver grade, BMI, and %TWL (P < 0.05)., Conclusion: Bariatric surgery can play a vital role in reducing the weight and severity of metabolic-associated fatty liver disease., (© 2024.

- Abstract
Heat Shock Protein 27 (HSP27), an anti-HBV factor, exists in the intracellular and extracellular spaces. As an inflammatory modulator, serum HSP27 (sHSP27) is associated with elevated pro-inflammatory cytokines and a higher likelihood of hepatocellular carcinoma in chronic hepatitis. SHSP27 results in natural antibody production (anti-HSP27-Ab) that is more stable and easily detectable compared to sHSP27. We aimed to investigate any potential association between anti-HSP27-Ab level and chronic hepatitis B (CHB) progression and inflammation indicated by liver cell injury and HBV replication. This cross-sectional study was conducted on 91 patients with CHB and 92 individuals without CHB. Following demographic data collection, anti-HSP27-Ab, serum lipids including total cholesterol, triglyceride, LDL-C, HDL-C, and aminotransferase levels were measured using enzymatic assays in participants' serum samples. HBV DNA was also measured by quantitative PCR in CHB patients. Bivariate and multivariate analyses showed a significantly higher mean level of anti-HSP27-Ab in CHB than in healthy individuals (0.304 vs. 0.256AU/ml, P value = 0.015). These levels held significant differences in the CHB subgroups of male patients, at the age of 50 years and above, with non-smoking status, elevated aminotransferase levels, and hypotriglyceridemia ( P value < 0.05). However, no difference was found between the antibody levels and HBV DNA copies ( P value > 0.05). This study provides evidence that anti-HSP27 antibody levels can reflect the degree of liver necrosis indicated by aminotransferase levels. Regarding the higher incidence rate of HBV-associated complications in 50 to 60-year-old men, monitoring the antibody can be beneficial in managing this group of CHB patients, which deserves further investigation., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© The Author(s), under exclusive licence to Association of Clinical Biochemists of India 2023.

- Abstract
Introduction: One of the main complications of multiple sclerosis (MS) is imbalance and walking problems that can lead to falls. This study investigated the association between a fall measurement scale called the Hopkins Falls Grading Scale (HFGS) and motor function tests in patients with MS., Material and Methods: This cross sectional study was conducted using convenience sampling on 85 patients referred to the MS Association of Mashhad, Iran, in 2023. The HFGS examined falls during the past year and divided them into 4 degrees, and the function test included the timed 25 foot walk (T25FW) test and the timed up and go (TUG) test. Kruskal-Wallis test and Spearman's correlation coefficient were used for data analysis., Results: A statistically significant association was obtained between HFGS and functional tests (T25FW and TUG) (for both P < 0.0001). A significant association was observed between the variables of age ( P = 0.006), duration of the disease ( P = 0.03), the use of mobility devices ( P = 0.05), and HFGS., Conclusion: Considering the association between HFGS and motor function tests in MS patients, clinical experts should pay attention to patients who have slower movement and evaluate them in terms of falling status when performing motor function tests., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Family Medicine and Primary Care.)

- Abstract
Objective: The current study aimed to identify the association between COVID-19 vaccination and prolonged post-COVID symptoms (long-COVID) in adults who reported suffering from this condition., Methods: This was a retrospective follow-up study of adults with long-COVID syndrome. The data were collected during a phone call to the participants in January-February 2022. We inquired about their current health status and also their vaccination status if they agreed to participate., Results: In total, 1236 people were studied; 543 individuals reported suffering from long long- COVID (43.9%). Chi square test showed that 15 out of 51 people (29.4%) with no vaccination and 528 out of 1185 participants (44.6%) who received at least one dose of any vaccine had long long- COVID symptoms (p = 0.032)., Conclusions: In people who have already contracted COVID-19 and now suffer from long-COVID, receiving a COVID vaccination has a significant association with prolonged symptoms of long-COVID for more than one year after the initial infection. However, vaccines reduce the risk of severe COVID-19 (including reinfections) and its catastrophic consequences (e.g., death). Therefore, it is strongly recommended that all people, even those with a history of COVID-19, receive vaccines to protect themselves against this fatal viral infection., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Asadi-Pooya et al.

- Abstract
A highly sensitive colorimetric method (glycan-based nano(e)zyme) was developed for sensitive and rapid detection of the SARS-CoV-2 virus based on N-acetyl neuraminic acid (sialic acid)-functionalized gold nanoparticles (SA-Au NZs). A number of techniques were used to characterize the prepared nanomaterials including XRD, FT-IR, UV-vis, DLS, and TEM. DLS analysis indicates an average hydrodynamic size of 34 nm, whereas TEM analysis indicates an average particle size of 15.78 nm. This observation confirms that water interacts with nanoparticle surfaces, resulting in a large hydrodynamic diameter. The peroxidase-like activity of SA-Au NZs was examined with SARS-CoV-2 and influenza viruses (influenza A (H1N1), influenza A (H3N2), and influenza B). UV-visible spectroscopy was used to monitor and record the results, as well as naked eye detection (photographs). SA-Au NZs exhibit a change in color from light red to purple when SARS-CoV-2 is present, and they exhibit a redshift in their spectrum. N-acetyl neuraminic acid interacts with SARS-CoV-2 spike glycoprotein, confirming its ability to bind glycans. As a result, SA-Au NZs can detect COVID-19 with sensitivity and specificity of over 95% and 98%, respectively. This method was approved by testing saliva samples from 533 suspected individuals at Ghaem Hospital of Mashhad, Mashhad, Iran. Sensitivity and specificity were calculated by comparing the results with the definitive results. The positive results were accompanied by a color change from bright red to purple within five minutes. Statistical analysis was performed based on variables such as age, gender, smoking, diabetes, hypertension, and lung involvement. In clinical trials, it was demonstrated that this method can be used to diagnose SARS-CoV-2 in a variety of places, such as medical centers, hospitals, airports, universities, and schools., (© 2023.

- Abstract
Purpose: In this study, we investigated the effects of leukocyte- and platelet-rich fibrin (L-PRF) on implant stability and alterations in the marginal bone surrounding posterior maxillary implants., Methods: This randomized clinical trial was conducted to compare the variable of L-PRF placement around maxillary implants. Resonance frequency analysis (RFA) was used to evaluate the implant stability immediately after surgery and at 1, 2, 4, 6, 8, and 12 weeks after surgery (t
0 to t6, respectively). In addition, the amount of marginal bone changes around the implant at t6 was compared with the baseline using periapical radiography., Results: The RFA outcomes were statistically significant within each group (P < 0.001, Eta2 = 0.322); however, in none of the follow-ups and immediately after the surgery, there was a significant difference between the two groups in terms of the implant stability quotient (ISQ) scores (P > 0.05). At t0 , the test and control groups' respective mean levels of marginal bone loss around the implants were 0.4836 mm and 0.7343 mm, significantly different from the corresponding values at t6 . On the other hand, marginal bone loss around the implant was not significantly different between the two groups in t0 and t6 (P = 0.532)., Conclusions: L-PRF did not improve the RFA outcomes of implants three months after implant placement, and changes in the ISQ values over time were the same in both groups. In addition, L-PRF had no superior effect on the marginal bone loss around the implants., Trial Registration Number: The research was registered in the Iranian Registry of Clinical Trials on 22 December 2020 (No: IRCT20200624047906N1), available at http://www.irct.ir., (© 2023.

- Abstract
Objective: The present study was conducted to compare the effects of 810 nm, 980 nm, and dual (810: 50%-980: 50%) diode lasers on the surface modifications of implants contaminated by a standard strain of Escherichia coli . Methods: Based on the operation on their surface, the implants were divided into six groups: "Group 1" was the positive control group undergoing no specific procedures. "Groups 2, 3, 4, 5, and 6" were contaminated by a standard strain of E. coli ; "Group 2" was also set as the negative control group. "Groups 3, 4, and 5" were irradiated by 810 nm, 980 nm, and dual lasers (810: 50%-980: 50%; 1.5W, 320 μm fiber) for 30 sec, respectively. "Group 6" was treated using standard titanium brushes. All groups were examined to evaluate the surface modifications by the X-ray diffraction analysis, scanning electron microscope, and atomic force microscopy. Results: The values of carbon, oxygen, aluminum, titanium, and vanadium were significantly different in the surface composition of the contaminated implants from the control groups ( p = 0.010, 0.033, 0.044, 0.016, and 0.037, respectively). In all target areas, there were significant differences in surface roughness ( p < 0.0001); the same was also true about the pairwise comparison of the study groups ( p < 0.0001). "Group 5" demonstrated lower morphological surface changes and roughness degrees. Conclusions: Overall, laser irradiation could alter the surfaces of the contaminated implants. Titanium brushes and 810/980 nm lasers resulted in similar morphological alterations. Dual lasers enjoyed the least degree of morphological alterations and surface roughness.

- Abstract
Objective: To assess the influence of systemic sclerosis (SSc) on the survival rate of dental implants in SSc patients receiving implant-supported treatments., Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) Statement and the Cochrane Collaboration's guiding principles were followed during the study's execution. The data from three databases, PubMed, Google Scholar, and Scopus, available until January 2023, were used to compile the material for our research. Only English-language publications were submitted for this research and evaluated based on their titles, abstracts, and full texts. For performing a quality assessment, quality scores were calculated., Results: The total number of patients and implants studied were 37 and 153, respectively, all having had scleroderma. The patients' ages ranged from 28 to 77 years old, with a mean (SD) age of 58.16 (12.88). All the patients in the case reports and most in the case series study were female. The range of follow-up duration was from 1 to 10 years. In case report studies, the survival rate was 100%; in case series, it was 89.2%., Conclusion: The SSc status had no discernible impact on the implant survival rate. Implant-based treatments in SSc patients should not worsen the overall morbidity and should not conflict with systemic treatments. Before starting implant therapy, a thorough risk assessment is essential, though., (© 2023 The Authors. Immunity, Inflammation and Disease published by John Wiley & Sons Ltd.)

- Abstract
Fluorophores emitting in the near-infrared (NIR) wavelength region present optimal characteristics for photonics and especially bioimaging. Unfortunately, only few NIR fluorescent materials are known, and even fewer are biocompatible. For this reason, the scientific interest in designing NIR fluorophores is very high. Egyptian Blue (CaCuSi
4 O10 , EB) is an NIR fluorescent layered silicate that can be exfoliated into fluorescent nanosheets (EB-NS). So far, its surface chemistry has not been tailored, but this is crucial for colloidal stability and biological targeting. Here, we demonstrate covalent surface functionalization of EB nanosheets (EBfunc) via Si-H activation using hydrosilanes with variable functionalities. In the first part of this work, EB-NS are grafted with the visible fluorescent pyrene (Pyr) moieties to demonstrate conjugation by colocalization of the Vis/NIR fluorescence on the (single) EB-NS level. Next, the same grafting procedure was repeated and validated with carboxyl group (COOH)-containing hydrosilanes. These groups serve as a generic handle for further (bio)functionalization of the EB-NS surface. In this way, folic acid (FA) could be conjugated to EB-NS, allowing the targeting of folic acid receptor-expressing cancer cells. These results highlight the potential of this surface chemistry approach to modify EB-NS, enabling targeted NIR imaging for biomedical applications.- Published

- Abstract
Introduction: We investigated the longevity of COVID-associated brain fog in patients who have survived the COVID-19., Methods: This was a follow-up study of 2,696 adult patients with COVID-19 from our previous study. We selected every other patient in our database. The follow-up data were collected during a phone call to the participants in January-February 2022 (11 months after the initial study): concentration difficulty and the patient's self-declared status in their ability to concentrate., Results: In total, 1,164 people were included; 35 people (3.0%) had concentration difficulty and 65 individuals (5.6%) had a worsened status in their ability to concentrate and think; 26 people (2.2%) responded yes to both questions and were considered as having long-lasting brain fog. People with long-lasting brain fog were more often admitted to ICUs during the initial hospitalization (23.1% vs. 9.3%; p = 0.032) compared with those without long-lasting brain fog., Conclusion: We may conclude that a minority of the hospitalized patients with COVID-19 may suffer from long-lasting post-COVID brain fog, at least for more than 1 year after their initial illness. Long-lasting post-COVID brain fog has a significant association with the severity of the initial illness., (© 2023 S. Karger AG, Basel.)

- Abstract
Introduction: Cancer remains a challenging issue against human health throughout the world; As a result, introducing novel approaches would be beneficial for cancer treatment. In this research, sodium butyrate (Sb) is one of the effective anti-cancer therapeutics (also a potent survival factor for normal cells) that was used for prostate cancer suppression in the platform of modified chitosan (CS) nano-complex (polyethylene glycol (PEG)-folic acid (FA)-Sb-CS). Methods: Different analytical devices including Fourier transform infrared, dynamic light scattering, high-performance liquid chromatography, scanning electron microscopy, and transmission electron microscopy were applied for the characterization of synthetics. On the other hand, biomedical tests including cell viability assay, molecular and functional assay of apoptosis/autophagy pathways, and cell cycle arrest analysis were potentially implemented on human PC3 (folate receptor-negative prostate cancer) and DU145 (folate receptor-positive prostate cancer) and HFF-1 normal cell lines. Results: The quality of the syntheses was effectively verified, and the size range from 140 to 170 nm was determined for the PEG-CS-FA-Sb sample. Also, 75 ± 5% of drug entrapment efficiency with controlled drug release manner (Sb release of 54.21% and 74.04% for pHs 7.4 and 5.0) were determined for nano-complex. Based on MTT results, PEG-CS-FA-Sb has indicated 72.07% and 33.53% cell viability after 24 h of treatment with 9 mM on PC3 and DU145 cell lines, respectively, which is desirable anti-cancer performance. The apoptotic and autophagy genes overexpression was 15-fold (caspase9), 2.5-fold (BAX), 11-fold (ATG5), 2-fold (BECLIN1), and 3-fold (mTORC1) genes in DU145 cancer cells. More than 50% of cell cycle arrest and 45.05% of apoptosis were obtained for DU145 cancer cells after treatment with nano-complex. Conclusion: Hence, the synthesized Sb-loaded nano-complex could specifically suppress prostate cancer cell growth and induce apoptosis and autophagy in the molecular and cellular phases.

- Abstract
Introduction: In late December 2019, a sudden severe respiratory illness of unknown origin was reported in China. In early January 2020, the cause of COVID-19 infection was announced a new coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Examination of the SARS-CoV-2 genome sequence revealed a close resemblance to the previously reported SARS-CoV and coronavirus Middle East respiratory syndrome (MERS-CoV). However, initial testing of drugs used against SARS-CoV and MERS-CoV has been ineffective in controlling SARS-CoV-2. One of the key strategies to fight the virus is to look at how the immune system works against the virus, which has led to a better understanding of the disease and the development of new therapies and vaccine designs. Methods: This review discussed the innate and acquired immune system responses and how immune cells function against the virus to shed light on the human body's defense strategies. Results: Although immune responses have been revealed critical to eradicating infections caused by coronaviruses, dysregulated immune responses can lead to immune pathologies thoroughly investigated. Also, the benefit of mesenchymal stem cells, NK cells, Treg cells, specific T cells, and platelet lysates have been submitted as promising solutions to prevent the effects of infection in patients with COVID-19. Conclusion: It has been concluded that none of the above has undoubtedly been approved for the treatment or prevention of COVID-19, but clinical trials are underway better to understand the efficacy and safety of these cellular therapies., Competing Interests: Authors declare no conflict of interest in this study., (© 2023 The Author(s).)

- Abstract
Vitiligo is a recalcitrant depigmentary autoimmune skin disorder. Hydroxychloroquine (HCQ) is an effective immunomodulatory drug which is widely used in treatment of autoimmune disorders. HCQ-induced pigmentation has been previously found in patients taking HCQ due to other autoimmune diseases. The present study aimed to determine whether HCQ improves re-pigmentation of generalized vitiligo. HCQ was orally administered 400 mg daily (6.5 mg/Kg of body weight) by 15 patients with generalized vitiligo (more than 10% involvement of body surface area) for three months. Patients were evaluated monthly and skin re-pigmentation was assessed using the Vitiligo Area Scoring Index (VASI). Laboratory data were obtained and repeated monthly. Fifteen patients (12 women and 3 men) with a mean age of 30.13±12.75 years were studied. After 3 months, the extent of re-pigmentation on all the body regions, including the upper extremities, hands, trunk, lower extremities, feet, and head and neck was significantly higher than the baseline (P value <0.001, 0.016, 0.029, <0.001, 0.006, 0.006, respectively). Patients with concomitant autoimmune diseases had significantly more re-pigmentation compared with others (P=0.020). No irregular laboratory data were observed during the study. HCQ could be an effective treatment for generalized vitiligo. The benefits are likely to be more evident in case of concomitant autoimmune disease. The authors recommend additional large-scale controlled studies to draw further conclusions.

- Abstract
Aim: We aimed to describe the long-term outcome with respect to symptom persistence amongst children hospitalised for COVID-19., Methods: This was a follow-up study of 58 children and adolescents hospitalised with COVID-19. For all patients, the data were collected in a phone call to the family in December 2021 (9 months after the initial study and more than 13 months after their admission to hospital). We inquired about their current health status and obtained information, if the responding parent consented orally to participate and answer the questions., Results: Fifty-one children and adolescents were studied. Only five patients (10%) had persistent symptoms compatible with long-COVID; the reported symptoms include fatigue in four (8%), weakness in three (6%), exercise intolerance in two (4%) and shortness of breath in two (4%) patients. Four patients (7.8%), who did not have any symptoms of long-COVID in phase 1 of the study, reported new-onset symptoms or complaints that are potentially compatible with the diagnosis of long-COVID (weakness, myalgia, excess sputum, cough, fatigue) in the current phase., Conclusions: Symptom persistence of long-COVID is infrequent amongst children hospitalised for COVID-19. Most of the symptoms of long-COVID will resolve with the passage of time and the residual symptoms are often mild and tolerable. The scientific community should carefully and clearly define long-COVID and its natural course in order to facilitate and harmonise future studies., (© 2022 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

- Abstract
Coronavirus disease 2019 (COVID-19) can be fatal in severe cases. Accordingly, predicting the severity and prognosis of the disease is valuable. This study examined the role of electrolyte imbalances in predicting the severity of COVID-19. In this cross-sectional study, 169 hospitalized patients with COVID-19 were included and categorized into three groups based on the severity of the disease (moderate, severe, and critical). Serum levels of electrolytes (calcium [Ca], phosphorus [P], sodium [Na], potassium [k], and magnesium [Mg]), inflammatory markers (D-dimer, C-reactive protein [CRP], ferritin, and lactate dehydrogenase [LDH]), and 25OHVitamin D were measured. The mean age of patients was 53 years, and 54% were male. They had moderate, severe, and critical illnesses in 22%, 47%, and 31%, respectively. CRP, D-dimer, and ferritin increased with the severity of the disease. The lower median values of Mg, Na, 25OHVitamin D, Ca, LDH, and higher median lymphocyte counts were observed in the moderate vs. the severe group (P < 0.05). These parameters have acceptable sensitivity and specificity at the suggested cut-off level to discriminate the moderate and critical cases. Serum parameters introduced in this study are appropriate for differentiating between critical and moderate cases. The electrolyte imbalance can predict critical patients., (© 2022. The Author(s).)

- Abstract
Objectives: Antiepileptic drugs are among the most common triggers of cutaneous adverse reactions. About 5-17% of epileptic patients develop idiosyncratic skin reactions at some point during their treatment course, most of which occur within the first two months of drug initiation. This study aimed to investigate the pattern of cutaneous drug reactions associated with anticonvulsant use among the pediatric population in Iran to identify high-risk individuals., Materials & Methods: In this retrospective descriptive study, medical records of children aged two months to 14 years, who were diagnosed with drug reactions due to anticonvulsant drugs between April 2007 and March 2018, were reviewed, and relevant information were extracted. This multicenter study was conducted in several provinces of Iran., Results: A total of 186 cases with a final diagnosis of the antiepileptic drug-induced eruption were evaluated. The median age of participants was 36 months (range: 2-168), and 56% were male. In approximately 70% of the children, the phenobarbital was the culprit. The median time interval between initiation of the causative drug and development of rash and fever was 10 and 7 days, respectively. The most common rash type was maculopapular rashes (69%). Overall, 33% of the patients only received antihistamines after discontinuation of the causative drug., Conclusion: Similar to previously published studies in Iran, phenobarbital was the main cause of cutaneous drug reactions to antiepileptic drugs, indicating the necessity of paying more attention when prescribing phenobarbital for Iranian pediatrics., Competing Interests: None, (© 2022 The Authors.)

- Abstract
Purpose: Despite the promising therapeutic effects of gene silencing with small interfering RNAs (siRNAs), the challenges associated with delivery of siRNAs to the tumor cells in vivo , has greatly limited its clinical application. To overcome these challenges, we employed gold nanoparticles modified with trimethyl chitosan (TMC) as an effective delivery carrier to improve the stability and cellular uptake of siRNAs against epidermal growth factor receptor (EGFR) that is implicated in breast cancer. Methods: AuNPs were prepared by the simple aqueous reduction of chloroauric acid (HAuCl
4 ) with ascorbic acid and coated with synthesized TMC. EGFR-siRNA was then complexed with the AuNPs-TMC via electrostatic interaction to make AuNPs-TMC/EGFR-siRNA with a w/w ratio of 10:1. Nanoparticles were assessed for physicochemical characteristics and in vitro cellular behavior on MCF-7 breast cancer cell line. Results: Spherical and positively charged AuNPs-TMC (67 nm, +45 mV) were successfully complexed with EGFR-siRNA (82 nm, +11 mV) which were able to retard the gene migration completely. Confocal microscopy and flow cytometry analysis demonstrated complete cellular uptake of Cy5 labeled AuNPs-TMC in the MCF-7 cells after 4 h incubation. MTT test after 48 h incubation showed that the AuNPs-TMC were safe but when combined with EGFR-siRNA exert significant cytotoxicity while the cell viability was about 50%. These nanocomplexes also showed a high gene expression knockdown (86%) of EGFR and also a high apoptosis rate (Q2 + Q3 = 18.5%) after 24 h incubation. Conclusion: This study suggests that the simply synthesized AuNPs-TMC are novel, effective, and promising nanocarriers for siRNA delivery, and AuNPs-TMC/EGFR-siRNA appears to be a potential therapeutic agent for breast cancer treatment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Baghani, Noroozi Heris, Khonsari, Dinarvand, Dinarvand and Atyabi.)- Published

- Abstract
Background: Traumatic brain injury (TBI) is a major cause of death and disability. TBI can result in neuropsychiatric and cognitive problems as well as neurodegenerative pathologies that can appear right after or develop and persist years after injury., Method: We conducted a double-blind, randomized, placebo-controlled clinical trial on patients who suffered from TBI three months to three years ago. The patients were randomized to placebo (n = 34) or K-Vie™ group (n = 46) for a treatment period of 3 months. The main primary outcomes include cognitive assessment in the Rey Auditory Verbal Learning Test-Recognition Test (RAVLT), Wechsler adult intelligence Digit Symbol Substitution Test (DSST) and trail-making test part B (TMT-B). Assessments were performed at baseline and at the month 3 follow-up visit. Linear mixed models were carried out to evaluate cognitive changes from baseline across all cognitive assessment tests., Result: The current study showed significant (p < 0.05) improvement in cognitive function of patients who were given K-Vie™ compared with placebo across the RAVLT, DSST and TMT-B performance assessments. A larger cohort would be beneficial to further confirm the clinical utility of K-Vie™ and assess its effects in acute phases of TBI.

- Abstract
The present study was conducted to investigate the detection and identification of Cryptosporidium species via molecular techniques and evaluate the serum concentrations of inflammatory factors in Cryptosporidium species. The fecal samples (n = 256) were collected from pre-weaned (≤ 2.00 months) calves and the positive samples were identified utilizing Ziehl-Neelsen staining. Nested species-specific multiplex PCR (nssm-PCR) and restriction fragment length polymorphism (RFLP) were used to identify the species and sub-species. The serum concentrations of IL-1β, IL-6, IL-12, TNF-α, and IFN-γ were also assessed. The results revealed that 10.54% of samples were positive. The results of Nested-PCR showed that 92.59% of the samples were positive for C. parvum while 7.41% were positive for C. andersoni . The results of RFLP confirmed 92.59% of the samples for C. parvum , 3.70% for C. muris / C. andersoni , and 3.70% for C. muris . The serum concentrations of IL-1β, IL-6, IL-12, TNF-α, and IFN-γ were significantly higher in the infected calves compared to those in healthy calves. However, the serum concentration of IFN-γ was significantly higher in the calves infected with C. parvum while the serum concentrations of TNF-α and IL-6 were significantly higher in those infected with C. andersoni . In conclusion, C. parvum was prevalent in the region and the calves demonstrated inflammatory responses to Cryptosporidium species., Competing Interests: The authors have no conflict of interest to declare., (© 2022 Urmia University.

Botshekan M and Ulm FJ
- Abstract
We investigate the spatial and temporal memory effects of traffic density and velocity in the Nagel-Schreckenberg cellular automaton model. We show that the two-point correlation function of vehicle occupancy provides access to spatial memory effects, such as headway, and the velocity autocovariance function to temporal memory effects such as traffic relaxation time and traffic compressibility. We develop stochasticity-density plots that permit determination of traffic density and stochasticity from the isotherms of first- and second-order velocity statistics of a randomly selected vehicle. Specifically, provided ergodicity and stationarity, these stochasticity-density plots permit a direct determination of traffic properties from crowdsourced measurements of velocities of vehicles. We illustrate the predictive prowess of the approach for crowdsourced vehicle speed data collected by anonymous smartphone measurements for the state of Massachusetts, USA, as a powerful alternative to classical traffic property estimates from spatially distributed user counts.

- Abstract
Purpose: To compare two methods for treating inferior oblique overaction (IOOA): disinsertion versus myectomy of the muscle., Methods: In this prospective interventional case series, patients were randomly assigned to undergo either IO myectomy or disinsertion. The changes in vertical and horizontal deviations following these two surgical procedures were evaluated. The postoperative IO function of grade 0 or +1 and the fundus extorsion of grade 0 or +1 was considered as the successful outcome., Results: Thirty-six patients (50 eyes) with a mean age of 12.67 ± 4.05 years were included. In the myectomy group, the mean preoperative hyperdeviation in adduction was 29.5 ± 9.32 prism diopter (PD), which decreased to 9.15 ± 7.86 PD after surgery ( P = 0.001). In the disinsertion group, these measurements were 32.73 ± 12.42 and 12.65 ± 9.34 PD before and after the surgery, respectively ( P = 0.001). The success rate of surgery based on the IOOA grading was 87.4% and 92.3% in the myectomy and disinsertion groups, respectively ( P = 0.780). The successful correction rate of abnormal fundus torsion was 91.6% in the myectomy and 88.4% in the disinsertion group ( P = 0.821). In comparison, 48% of the cases in the myectomy group and 50% in the disinsertion group were within the normal range of torsional position postoperatively ( P = 0.786). There was no statistically significant difference in terms of changes in the horizontal or vertical deviations, V-pattern, and dissociated vertical deviation between the two groups., Conclusion: Both surgical techniques seem to be effective for treatment of inferior oblique muscle overaction., Competing Interests: The authors do not have any conflicts of interest., (Copyright © 2021 Abri Aghdam et al.)

- Abstract
Autophagy is an intracellular process involving double-membrane vacuoles that ultimately merge with the lysosomes and play a key role in the inhibition of herpessimplex virus 1 (HSV-1) proliferation. This virus is an agent of some lethal neuronal diseases like encephalitis. HSV-1 requires the expression of its latent proteins, such as ICP34.5, to promote cell infection, which disrupts the autophagy process. In this study, we aimed to evaluate the effect of autophagy induction on HSV-1 replication in host cells at the early and late stages of its replication. Furthermore, we explored the consequences of autophagy induction before and after cell infection.Cells were transfected through Beclin-1-expressing plasmids. Autophagy induction was performed with microtubule-associated protein 1 light chain 3 (LC3-II) as an autophagosome formation marker by using flow cytometry. In the first stage, HSV-1 was inoculated into transfected cells 18 hours post-transfection. Next, viral DNA was extracted 18 and 48 hours post-infection, and eventually viral copies per milliliter were calculated through real-time polymerase chain reaction (PCR). For the second stage, the plasmid containing Beclin-1 was transfected to the cells following virus inoculation to examine the influence of autophagy induction after cell infection.Study results have shown that in neuroblastoma cells autophagy activation reduces virus yield from 4×10
5 copies/ml (control sample) to 9×104 copies/ml at 24 h postinfection and viral load after 48 h declines up to 1×106 copies/ml, which is less than that of the control sample about 5 logs. However, in HeLa cells, we observed a significant reduction in autophagy induction with reducing HSV-1 propagation. Despite these results, HSV-1 proliferation in both cell types increased and these viruses were able to maintain their ability to propagate even in high autophagic activity. Hyperactivation of autophagy can only slow the rate of virus replication. This study may provide new insight into the effect of autophagy on HSV-1 replication., (Copyright © 2020 Elsevier Ltd.

Background: Limited information is available on the effect of anaphylaxis, a severe, potentially life-threatening allergic reaction, in the elderly population., Objective: To elucidate the frequency of anaphylaxis and the demographic characteristics of elderly patients admitted to New York hospitals from 2000 to 2010., Methods: A retrospective analysis of hospitalized patients aged 65 years and older in New York from 2000 to 2010 was conducted using the Statewide Planning and Research Cooperative System, a statewide administrative database. Cases were identified using anaphylaxis International Classification of Diseases, Ninth Revision (ICD-9) codes or an ICD-9-based diagnostic algorithm incorporating the National Institutes of Allergy and Infectious Disease diagnostic criteria. The χ
2 test was used to measure the association between demographic characteristics and group membership. Regression was used to model group and age as a function of hospital rates., Results: A total of 3673 hospitalizations were analyzed. Anaphylaxis ICD-9 codes identified 1790 cases (48.7%), the algorithms identified 1701 cases (46.3.%), and 182 cases (5.0%) were identified by both. Hospitalization rates increased significantly during this period (P < .001). Women comprised 61.5% and people of white race comprised 69.8% of the sample. Distribution by age differed by ascertainment method (ICD-9 vs algorithm) among the early-old group (65-74 years of age; 53.8% vs 41.8%) and among the late-old group (≥85 years of age; 11.2% vs 19.3%)., Conclusion: Hospitalization rates and anaphylaxis cases increased during the study period among the hospitalized elderly population of New York. Relying on anaphylaxis ICD-9 codes alone missed approximately half of possible cases. The identification and possibly the effect of anaphylaxis among the elderly population may differ, depending on age, race, payer, New York County, and disposition., (Copyright © 2020 American College of Allergy, Asthma & Immunology.

- Abstract
Cells use biomolecules to convey information. For instance, neurons communicate by releasing chemicals called neurotransmitters, including several monoamines. The information transmitted by neurons is, in part, coded in the type and amount of neurotransmitter released, the spatial distribution of release sites, the frequency of release events, and the diffusion range of the neurotransmitter. Therefore, quantitative information about neurotransmitters at the (sub)cellular level with high spatiotemporal resolution is needed to understand how complex cellular networks function. So far, various analytical methods have been developed and used to detect neurotransmitter secretion from cells. However, each method has limitations with respect to chemical, temporal and spatial resolution. In this review, we focus on emerging methods for optical detection of neurotransmitter release and discuss fluorescent sensors/probes for monoamine neurotransmitters such as dopamine and serotonin. We focus on the latest advances in near infrared fluorescent carbon nanotube-based sensors and engineered fluorescent proteins for monoamine imaging, which provide high spatial and temporal resolution suitable for examining the release of monoamines from cells in cellular networks., (© 2020 The Authors.

- Abstract
Objectives: Mycobacterium tuberculosis ( M. tuberculosis ), an intracellular pathogen, causes 1.5 million deaths globally. Bacilli Calmette-Guérin (BCG) is commonly administered to protect people against M. tuberculosis infection; however, there are some obstacles with this first-generation vaccine. DNA vaccines, the third generation vaccines, can induce cellular immune responses for tuberculosis (TB) protection. In this study, optimized DNA vaccine (pcDNA3.1-Mtb72F) entrapped in poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) was used to achieve higher immunogenicity., Materials and Methods: Plasmid Mtb72F was formulated in PLGA NPs using double emulsion method in the presence of TB10.4 and/or CpG as an adjuvant. Female BALB/c mice were immunized either with NP-encapsulated Mtb72F or naked Mtb72F with or without each adjuvant, using the BCG-prime DNA boost regimen., Results: These NPs were approximately 250 nm in diameter and the nucleic acid and protein encapsulation efficiency were 80% and 25%, respectively. The NPs smaller than 200 nm are able to promote cellular rather than humoral responses. The immunization with the formulation consisting of Mtb72F DNA vaccine and TB10.4 entrapped in PLGA NPs showed significant immunogenicity and induced predominantly interferon-ɣ (IFN-ɣ) production and higher INF-ɣ/interleukin-4 (IL-4) ratio in the cultured spleen cells supernatant., Conclusion: PLGA NPs loaded with Mtb72F DNA-based vaccine with TB10.4 could be considered as a promising candidate for vaccination against TB. These results represent an excellent initial step toward development of novel vaccine for TB protection.

- Abstract
RNA interference is one of the prosperous approaches for cancer treatment. However, small interfering RNA (siRNA) delivery to cancer cells has been faced with various challenges restricting their clinical application over the decades. Since ROR1 is an onco-embryonic gene overexpressed in many malignancies, suppression of ROR1 by siRNA can potentially fight cancer. Herein, a delivery system for ROR1 siRNA based on HIV-1 TAT peptide-capped gold nanoparticles (GNPs) was developed to treat breast cancer. Besides, we introduced a new feasible method for conjugating the peptide to the nanoparticles. Since the GNPs have high affinity to the sulfur, the findings demonstrated the peptide successfully conjugated to the nanoparticles via Au-S bonds. As positively charged nanoparticles showed high cellular uptake, we could use a low concentration of nanoparticles led to high efficient gene transfection with negligible cytotoxicity that was confirmed by flow cytometry, confocal microscopy, gel retardation, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Following transfection, downregulation of ROR1 and its targeted gene, CCND1, induced apoptosis in cancer cells. In conclusion, the reported capped GNPs could be potentially utilized for delivering negatively charged therapeutic agents in particular genes., (© 2019 Wiley Periodicals, Inc.)

- Abstract
Background: Survival time is one of the indicators used for evaluation of the quality of care in different types of malignancies, including breast cancer. The present study aimed to estimate the survival rate of breast cancer and its related factors among Iranian patients., Methods: Overall, 3148 cases of breast cancer who referred to the Cancer Research Center in Shahid Beheshti University of Medical Sciences, Tehran, Iran during 1994-2017 participated in this longitudinal study. Survival estimates were calculated using the Kaplan-Meier method and the Bayesian generalized Birnbaum-Saunders model with cure rate from geometric distribution. Clinical, pathological, and biological variables as potential prognostic factors were entered in univariate and multivariate analyses.In order to identify the significant prognostic factors, 95% highest posterior density (HPD) intervals were used., Results: The overall 1, 5, 10, 15, 20 and 25-year survival rate were 95%, 75%, 60%, 47%, 46% and 46%, respectively. A significant relation was observed between survival time and the variables such as age, size of tumor, number of lymph nodes, stage, histological grade, estrogen receptor, progesterone receptor, and lymphovascular invasion., Conclusion: The findings of this study might help the health managers to plan long-term programs considering regional determinants, public education, and screening for early detection of breast cancer cases which can eventually influence the overall survival rate of these patients., Competing Interests: Conflict of interests The authors declare that there is no conflict of interest., (Copyright© Iranian Public Health Association & Tehran University of Medical Sciences.)

- Abstract
Serotonin is an important neurotransmitter involved in various functions of the nervous, blood, and immune system. In general, detection of small biomolecules such as serotonin in real time with high spatial and temporal resolution remains challenging with conventional sensors and methods. In this work, we designed a near-infrared (nIR) fluorescent nanosensor (NIRSer) based on fluorescent single-walled carbon nanotubes (SWCNTs) to image the release of serotonin from human blood platelets in real time. The nanosensor consists of a nonbleaching SWCNT backbone, which is fluorescent in the beneficial nIR tissue transparency window (800-1700 nm) and a serotonin binding DNA aptamer. The fluorescence of the NIRSer sensor (995 nm emission wavelength for (6,5)-SWCNTs) increases in response to serotonin by a factor up to 1.8. It detects serotonin reversibly with a dissociation constant of 301 nM ± 138 nM and a dynamic linear range in the physiologically relevant region from 100 nM to 1 μM. As a proof of principle, we detected serotonin release patterns from activated platelets on the single-cell level. Imaging of the nanosensors around and under the platelets enabled us to locate hot spots of serotonin release and quantify the time delay (≈ 21-30 s) between stimulation and release in a population of platelets, highlighting the spatiotemporal resolution of this nanosensor approach. In summary, we report a nIR fluorescent nanosensor for the neurotransmitter serotonin and show its potential for imaging of chemical communication between cells.

- Abstract
Hypothesis: Rhinoplasty is one of the most common aesthetic surgeries. The aim of the study was to evaluate facial proportions and patient satisfaction with the appearance of their nose after rhinoplasty compared to preoperatively., Methods: This cross-sectional study was conducted at Islamic Azad University, Mashhad Branch. Eighty-two candidates with indications for primary cosmetic rhinoplasty were selected. Facial proportions and patient satisfaction with their nasal appearance were evaluated before and 6 months after rhinoplasty. Patient satisfaction was assessed using the Rhinoplasty Outcome Evaluation questionnaire., Results: Eighty-two patients referred for cosmetic rhinoplasty (13.4% men and 86.6% women) with a mean age of 28.5 (6.4) years underwent open rhinoplasty and were evaluated. Facial proportions, including nasofrontal, nasolabial, and nasomental ratios increased significantly, while the nasofacial ratio, nasal tip projection, columellar show, alar base, and nasal length reduced significantly after rhinoplasty ( P < .05). Furthermore, patient satisfaction with the appearance of their nose increased significantly after surgery ( P < .001)., Conclusion: All of the facial proportions changed significantly following rhinoplasty. Although patient satisfaction with nose appearance increases significantly after the operation, there is no significant association between patient satisfaction and facial proportions. As beauty is a subjective, relative and qualitative issue, facial proportions may not be a proper tool to determine facial beauty and predict the satisfaction rate following rhinoplasty., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Some of the single-nucleotide polymorphisms in miRNA genes have been studied to date to find their association with the risk of breast cancer (BC). However, no study has been conducted to investigate the association of the mir-520f rs75598818G>A in BC. In the present study, rs75598818 association with BC in an Iranian population has been investigated, and an in silico analysis was performed to predict the function of rs75598818 polymorphism in BC. The rs75598818 was genotyped in 129 BC patients and 144 healthy women, using the PCR-RFLP method. The frequency of alleles and genotypes were considered to find the associations between rs75598818 alleles/genotypes, and BC risk and pathological characteristics of the patients. Statistical analysis showed that the rs75598818 GA genotype was significantly associated with BC (GA versus GG, OR=0.50, 95% CI: 0.25-0.98, P =0.041), highstage BC (stage III/IV versus I/II, GA versus GG, OR=0.27, 95% CI: 0.09-0.81, P =0.015), and HER-2 positive status (GA versus GG, OR=19.00, 95% CI: 4.64-77.82, P <0.001). Notably, the rs75598818 GA genotype has a negative association pattern since it reduces the risk of BC and high stage BC. Conversely, it increases the risk of HER-2 positivity. Computational results suggested that the rs75598818 polymorphism affects the stability of mir-520f stem-loop and as a result miR-520f -3p production that is a potential tumour suppressor. A contribution of the mir-520f rs75598818 polymorphism to BC had been unexplored before. In the present study, we performed an association study and a bioinformatics approach to evaluate this polymorphism in BC. However, further functional experiments and large-scale association studies with various ethnicities are required to elaborate our findings.

- Abstract
miR-145 is a tumor suppressive miRNA which is abnormally reduced in different cancers. miR-145 overexpression reduces cancer migration, invasion, and cell adhesion. Increasing miR-145 level using suitable and efficient gene delivery systems could be valuable in cancer treatment. In this study, a redox-responsive miR-145 conjugated thiolated dextran (TD-miR) was prepared. Also, polyelectrolyte complexes (PECs) of TD-miR and chitosan were fabricated and decorated with anti nucleolin aptamer, AS1411 (apt-PEC). The size of the PECs was between 40-270 nm, and the zeta potential was varied according to the TD-miR to chitosan molar ratio. The outcomes of cellular studies indicated the excellence of the apt-PEC as a duel targeted delivery system and the PECs composed of chitosan 18 kDa with TD-miR to chitosan ratio of 5. TD-miR and the PECs are appropriate as the smart gene delivery systems which preserve and transfect the cargo and release it in cytoplasm., (Copyright © 2018. Published by Elsevier Ltd.)
