Rosa davurica is widely used to treat various kinds of diseases because of its high antioxidant, antiviral and anti-inflammatory activities. This use of plant-based materials as medicine is called phytomedicine and has been widely practiced since time immemorial. However, the pharmacological mechanism of R. davurica in skin photoaging is not yet fully understood. Therefore, this study was carried out to evaluate the recovery effects of R. davurica leaf extracts (RDE) in UVB-irradiated human skin keratinocytes (HaCaTs) and investigate whether RDE is a potential therapeutic agent against skin photoaging. The expression of aging-related markers including mitogen-activated protein kinases/activator protein 1 (MAPK/AP-1), nuclear factor-κB (NF-κB), and nuclear factor E2-related factor 2/heme oxygenase-1 (Nrf2/HO-1) was evaluated using Western blot analysis. The reactive oxygen species (ROS) was also used by FACS in HaCaTs. Findings indicated that RDE is efficient in scavenging free radicals and dose-dependently reducing ROS generation. Furthermore, RDE notably decreased UVB-induced matrix metalloproteinase-1 (MMP-1) expression through inhibition of MAPK/AP-1 and NF-κB signaling pathways as well as induced blocking of extracellular matrix (ECM) degradation in UVB-irradiated HaCaTs. In addition, RDE improved Nrf2/HO-1 signaling that increases oxidative defense capacity and enhances transforming growth factor-beta (TGF-β) signaling activation to promote procollagen type I synthesis, relieving UVB-induced skin cell damage. In conclusion, the protective effects of RDE on skin cellular components suggest that it has a high biological potential for skin protection from UVB-induced skin photoaging and is a good candidate for drug and cosmetic application.

The aim of this systematic review was to identify animal preclinical studies and randomized controlled trials that looked at the effects of R. damascena in any form on different mental diseases. Up to September 2021, the online databases of PubMed, Scopus, Embase, Web of Science, and Cochrane trials, as well as SID and MagIran, were searched. This study included 10 animal studies. Except for one research, the rest of the studies confirmed the positive effects of the plant in treatment of mental disorders. A total of 38 studies met the criteria for inclusion. Individuals who have encountered various sorts of mental problems, such as anxiety, sleep disturbance, and depressive disorder, were studied. R. damascena essential oil (EO), essence, extract, and dried plant were used in aromatherapy and oral administration. A decrease in sympathetic nervous system activity, induction of neurotransmitters, induction of nerve growth factors by neurogenesis and synaptogenesis mechanisms, a decrease in prolactin and an increase in noradrenaline, estradiol, and progesterone secretion are some of the mechanisms of action. In general, R. damascena is an effective herb for the treatment of mental disorders. However, further research timing and duration of intervention are needed to extrapolate the findings.

The ROSA robot (Medtech) has been shown to be a useful instrument in the surgeon's armamentarium for accurate placement of stereotactic electroencephlography depth electrodes. However, it has not yet been used as a navigation tool for lesion resection. Here, we demonstrate a novel adapter that allows the surgeon to use the ROSA robot with the NICO BrainPath for the resection of deep lesions.To demonstrate the utility of an adapter that allows the ROSA robot to be used in conjunction with the NICO BrainPath tube for lesion resection.A stainless steel adapter was made based on the specifications of the ROSA pointer instrument. Two 3D printed models were used to undergo a "mock" surgery using the adapter to assess for ease of use and applicability.The adapter allowed for adequate accessibility and visualization of the tumors in both mock cases. In addition, the stability of the ROSA robot and the design of the adapter allowed the surgeon to rest their hands on the instrument without jeopardizing its position.The ROSA adapter allowed for accurate navigation and exposure of these lesions, combining the accuracy and stability of the ROSA robot, with the retraction of the BrainPath tube.

To describe the epidemiology of laboratory-confirmed Diarrhoeagenic Escherichia coli (DEC) cases from active facility-based surveillance in Guatemala.We collected clinical and risk factor data on enrolled patients (aged 0-52 years) with acute diarrhoea at government healthcare facilities (1 hospital and 6 clinics) in Santa Rosa, Guatemala, during 2008-2009 and 2014-2015. Stool samples were analysed, E. coli identified through culture and biochemical tests, PCR amplification of genes encoding pathotype-specific virulence factors identified specific DEC pathotypes. Healthcare-seeking adjusted incidence rates were calculated.A total of 3041 diarrhoea cases were captured by surveillance (647 hospitalisations (H), 2394 clinic visits (CV)); general E. coli prevalence was 17.9%. DEC pathotypes were identified in 19% (n = 95/497) and 21% (n = 450/2113) in diarrhoea H and CV, respectively. Enteropathogenic E. coli (EPEC) was most frequently isolated (8.2% (n = 41) in diarrhoea H, 12.0% (n = 255) in diarrhoea CV), followed by ETEC (6.8% (n = 34) in H, 6% (n = 128) in CV) and STEC (0.6% (n = 3) in H, 0.6% (n = 13) in CV). We did not find evidence of a difference in severity between DEC and non-DEC diarrhoea. Incidence of DEC clinic visits and hospitalisations was 648.0 and 29.3, respectively, per 10,000 persons aged ≤5 years and 36.8 and 0.4, respectively, per 10,000 persons aged5 years.DEC pathotypes, especially EPEC and ETEC, were detected frequently from patients presenting with diarrhoeal illness in Santa Rosa, Guatemala. Our findings suggest that preventive interventions should be prioritised for young children.

Osteoarthritis and rheumatoid arthritis are the most common diseases of the musculoskeletal system, which greatly reduce the quality of life of people. In addition to non-steroidal anti- inflammatory drugs used in treatment, molecules isolated from natural sources are also considered as new options in the treatment of these inflammatory diseases. In this review, in vitro, in vivo and clinical studies on standardized rosehip (Rosa canina L.) fruits without seed used for joint health due to their anti-inflammatory, analgesic and antioxidant effects and active compounds isolated from these fruits are presented. It is reported that the anti-inflammatory action mechanism of standardized rosehip powder is due to its antioxidant activity, inhibiting NF-B signaling and pro-inflammatory enzymes, decreasing inflammatory cytokine and chemokine production, and lowering C reactive protein levels. The galactolipid (2S)-1,2-di-O-[(9Z,12Z,15Z)-octadeca-9,12,15- trienoyl]-3-O-ß-D-galactopyranosyl glycerol (GOPO), isolated from rosehip seeds and fruits, has been found to exhibit potent anti-inflammatory effects in vitro, clinically reducing the complaints of patients with osteoarthritis and improving their quality of life. Additionally, triterpene acid mixture (ursolic acid, oleanolic acid, and betulinic acid), also isolated from rosehip, has been reported to reduce the production of interleukin-6 and Tumor necrosis factor-α. Studies on the anti-inflammatory mechanism of action of rosehip and its active ingredients and their effects on osteoarthritis and rheumatoid arthritis have shown that more detailed clinical studies are required on standardized rosehip powders and preparations enriched in active compounds.

Background Oils in traditional medicine are important products and used routinely for therapeutic purposes. Rose oil (Rosa damascene Mill), a product of Persian medicine, is advised for the treatment of Infectious diseases related to the female genitourinary tract. In the present study, R. damascena petal oil, aqueous, and hydroalcoholic extracts were evaluated for their in vitro antibacterial and anti-Trichomonas vaginalis effects. Methods Anti-trichomonas activity evaluation of extracts and oil were assayed by the Homocytometery method. Their antibacterial effects against Escherichia coli, methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa, and clinically isolated Group B Streptococcus were assayed by broth microdilution in 96-well plates. Results The MIC of hydroalcoholic and aqueous extracts ranged from 25-50 and 25-100 mg/ml, respectively. Rose oil at all administered doses failed to show any antibacterial activity. Conclusion All extracts and oil concentrations showed some degree of growth inhibition activity on T. vaginalis; however, hydroalcoholic extract was more efficient.

Recent studies have reported conflicting findings on the antianxiety, antidepressant, and anti-stress properties of Rosa Damascena Mill (RDM). Therefore, the present systematic review and meta-analysis were conducted on the effects of RDM for treating anxiety, depression, and stress amongst adults. The online data sources of Cochrane Central Register of Controlled Trials, PubMed, Scopus, Web of Science, Embase, ProQuest, and Scientific Information Database were searched from inception to June 30, 2021. The randomized controlled trials (RCTs), which examined the effects of RDM (in any form of administration) on adults' anxiety, depression, and stress, were included. A random-effects model was applied to pool the data, and a total of 32 publications were included. The results of the meta-analysis revealed that administration of RDM significantly reduced state anxiety (effect size [ES]: 24, standardized mean difference [SMD]: -1.74, 95% confidence interval [CI]: -2.29, -1.20; p < .001), depression (ES: 7, SMD: -0.87, 95% CI: -1.47, -0.28; p = .004), and stress (ES: 4, SMD: -1.33, 95% CI: -1.98, -0.69; p < .001). However, the treatment had no significant effect on trait anxiety (ES: 6, weighted mean difference: -0.75, 95% CI: -1.93, 0.43; p = .214). The association between the total administration dosage and/or duration of RDM and the changes in state anxiety and depression was not dose-dependent. Most RCTs had a fair methodological quality based on the Cochrane risk of bias assessment tool. Besides, the quality of evidence ranged from very low to moderate according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Hence, further high-quality RCTs are needed to draw reliable conclusions regarding the use of RDM for treating adults' anxiety, depression, and stress.

The Scottish philosopher Thomas Reid and more recently the evolutionary psychologist Nicholas Humphrey argued for a basic distinction between sensation (what is happening to me) and perception (what is happening out there) with the former, but not the latter, being associated with consciousness. Conscious experiences in this view would emerge from changes in the state of the body, i.e. as bodily actions, and would maintain such a primal characteristic nowadays. I argue that the evolutionary reason for the sensation/perception distinction can be traced back to organisms' movement, and to the consequent need to tell apart two varieties of an otherwise identical local stimulation: namely, either as the outcome of external stimuli passively impinging on body surface or as the outcome of an organism movement giving rise to encountering with external stimuli. The Erich von Holst Reafferenzprinzip effectively modelled such a distinction by postulating that an efference copy is generated in association with the motor command thus nullifying any sensory signal that arises as a by-product of an organism movement. I argue that if sensation originally equates to a bodily action (or its internalized representation), then it could be that an efference copy of local (or internalized) bodily action is generated under stimulation and compared to that associated with active motor command. This way the result would be leaving sensation (what is happening to me) or nullifying it and leaving only perception (what is happening out there) depending on whether or not a motor command has occurred. Implications of this hypothesis for the presence of consciousness in animals or other organisms such as plants are briefly discussed.

In this research, the fruits and seeds' surface morphological features and their taxonomic significance were determined. Additionally, useful traits for delimitation of taxa of Rosa sericea complex were studied. In this research, three taxa of the complex R. sericea, R. omeiensis, and R. sikangensis have been studied. A total of 41 populations and 130 specimens of seeds, and 35 populations and 168 specimens of fruits from 10 different geographical regions of southwest China have been examined. The surface micro-morphological characters of the seeds have been studied through scanning electron microscopy to distinguish important characteristics of the complex taxa. Forty-four different qualitative and quantitative characteristics were observed. Principal component analysis was used to simplify and elucidate the relationship between the studied characters of different population based on the morphology of fruits and seeds' features. Moreover, the numerical taxonomic characters and their variation with elevation have been studied in these species. The most interesting characters observed on the surface of the seeds were stomata, and trichomes, for which density was more at the dorsal and ventral parts, while rarely present on the lateral parts. The fruits and seeds' surface morphology of the studied species was complicated and some variation in the characters, that is, persistent calyx shape, the shape of fruits and seeds, stomata shape, and trichomes size were found significant for delimitation of taxa in the complex. The purpose of this study is to identify the taxa of R. sericea complex based on fruits and seeds' morphological characters, and identification keys.

Background Dysmenorrhea is one of the most common disorders among young women. Medicinal herbs are one of the alternative methods for the treatment of dysmenorrhea. This study will investigate the effect of Rosa foetida extract, along with self-care behavior education on primary dysmenorrhea among female students of Babol University of medical sciences. Methods/design A randomized clinical trial will be performed on single students, aged 18 to 24 years. The research samples will be divided into three groups. The students will receive self-care behavior education on dysmenorrhea. Following the education, two of the groups will receive Rosa foetida extract capsules and placebo capsules in two consecutive cycles every 8 h for two successive days, respectively. The capsules will have similar physical appearance. The third group will not receive any medication. Data will be collected through demographic characteristic questionnaire, visual analog scale, dysmenorrhea self-care behaviors scale questionnaire, pictorial chart, and menstrual distress scale questionnaire. In order to determine and compare the effect of pharmacological and educational interventions on the severity of dysmenorrhea in groups, an ANOVA analysis of variance test with repeated measures will be used by SPSS software version 22. Discussion The results will show the effects of Rosa foetida extract along with self-care behavior education on primary dysmenorrhea, and beneficial effects that may be found in the trial of this plant may be of use for women with the same problem. Ethics and dissemination The study is approved by the Ethics Committee of Babol University of Medical Sciences (IR.MUBABOL.REC.1397.059). Trial registration IRCT 20190318043086N1.

How do the definitions between health promotion professions differ? Should the shift from using the term wellness to greater use of the well-being term challenge us to explain how our profession improves how people appraise their lives as a whole? After all, achieving well-being is a challenge as relevant to clergy, politicians, artists and entertainers as to health professionals. Successful organizations are keenly attentive to how they differentiate their services so as not to get lost in a sea of like competitors. The American College of Lifestyle Medicine has recently defined lifestyle medicine as a medical specialty delivered by certified clinicians. In contrast, the Society of Behavioral Medicine suggests that virtually any degree holder may be qualified to provide disease management and prevention services. If improved health is one of the surest ways to improve well-being, do we need to more clearly define the health promotion profession’s value proposition? How should definitions about differences between professions influence reimbursement differences between professions?

BackgroundMost ergonomics studies on office workstations evaluate the effects of an intervention only by subjective measures such as musculoskeletal pain and discomfort. Limited evidence has been provided regarding risk factor reduction in office environments through standardized methods assessments. The Rapid Office Strain Assessment (ROSA) tool can provide an estimation of risk factor exposure for office workers as a means by which the outcome of interventions can be quantified.PurposeThe aim of the study was to evaluate if ROSA scores reflect changes in risk factors after an ergonomics intervention among office workers.MethodsOffice workers (n = 60) were divided into two groups. The experimental group received a workstation intervention and the control group received no intervention. Changes in ROSA scores were compared before and after the intervention in both groups.ResultsStatistically significant reductions in the ROSA final and section scores occurred after the intervention in the experimental group with (mean reduction of 2.9, 0.8 and 1.6 points for sections A, B and C, respectively). In contrast, no differences were detected in the control group (mean increase of 0.1 point for sections A and C and mean reduction of 0.1 point for Section B).ConclusionsThese findings show that ROSA scores reflect changes in risk factors after an ergonomics intervention in an office environment. Consequently, this tool can be used for identifying and controlling risk factors among computer workers, before and after interventions.

Pain and anxiety are a major problem of burn patients. Despite the use of different medications, patients still suffer from these two problems. Aromatherapy along with medication may help in alleviating these symptoms. This study aimed to investigate the effect of inhalation aromatherapy with damask rose essence on pain and anxiety in burn patients.This three group clinical trial was conducted on 120 patients with burns less than 30% TBSA. The patients were randomly allocated into three groups, aromatherapy damask rose essence, placebo, and control. The pain intensity was assessed using visual analogue scale prior to intervention, immediately before, and 15 min after dressing. Anxiety was measured using Spielberger Inventory at before intervention and 15 min after dressing, also the prolonged effect of intervention on pain was assessed by number of the analgesics drugs received for four hours after dressing change. The intervention included inhalation of 6 drops of 40% damask rose essential oil in the damask group, and six drops of distilled water in placebo group one hour before dressing change. The control group received no intervention.Baseline state-trait anxiety and pain intensity were similar in these three groups (p0.05). We found a significant reduction in pain intensity immediately before and after dressing and state anxiety after dressing in the damask group compared to the placebo and control groups (p0.001). However, we found no significant difference between the placebo and control groups in terms of these variables at these times (p0.05). Also, we found no significant difference among three groups in frequency of analgesics drugs and trait anxiety after intervention (p0.05).Inhaled aromatherapy with Damask rose essence reduces subjective pain intensity and state anxiety in burned patients. Therefore, it is recommended considering use of damask rose essence, as an easy and affordable method along with other treatments.

Introduction In Mexico, there are considerable health system delays in the diagnosis and treatment initiation of women with breast cancer. Alerta Rosa is a navigation program in Nuevo Leon that aims to reduce barriers that impede the timely management of these patients. Patients and Methods Since December 2017, women who registered to receive medical evaluations by Alerta Rosa were stratified based on their clinical characteristics into three priority groups (“Red,” “Yellow,” and “Green”). According to the category assigned, patients were scheduled imaging studies and medical appointments with breast specialists on a preferential basis. Results Up until December 2019, 561 patients were scheduled for medical evaluations. Of them, 59% were classified as “Red,” 25% “Yellow,” and 16% “Green” priority. The median time from stratification to first medical evaluation was 4, 6, and 7 days, respectively (p = .003). Excluding those who had a prior breast cancer diagnosis, 21 patients were diagnosed by Alerta Rosa, with the initial “Red” priority classification demonstrating a sensitivity of 95% (95% confidence interval [CI], 75.1%–99.9%) and specificity of 42% (95% CI, 37.1%–47.1%) for breast cancer. The median time elapsed from initial patient contact to diagnosis and treatment initiation was 16 days and 39 days, respectively. The majority (72%) of patients were diagnosed at an early stage (0–II). Conclusion This patient prioritization system adequately identified women with different probabilities of having breast cancer. Efforts to replicate similar triage systems in resource-constrained settings where screening programs are ineffective could prove to be beneficial in reducing diagnostic intervals and achieving early-stage diagnoses. Implications for Practice Low- and middle-income countries such as Mexico currently lack the infrastructure to achieve effective breast cancer screening and guarantee prompt access to health care when required. To reduce the disease burden in such settings, strategies targeting early detection are urgently needed. Patient navigation programs aid in the reduction of health system intervals and optimize the use of available resources. This article presents the introduction of a triage system based on initial patient concern. Appointment prioritization proved to be successful at reducing health system intervals and achieving early-stage diagnoses by overcoming barriers that impede early access to quality medical care.

BACKGROUND Infrared freeze drying (IRFD) utilizes infraredradiationas a novel heating source in freeze drying (FD), leading to high-quality dehydrated products and less drying time. The present study aimed to investigate the effects of IRFD on the drying characteristics (drying time and energy consumption), volatiles, physical structure and nutritional properties ofRosa rugosaflower. In addition, freeze drying (FD) and hot air drying (HAD) were also evaluated in a comparison with the IFRD drying method with respect to product quality parameters. RESULTS Fifty-six volatile compounds were identified in fresh samples, whereas 53, 51 and 46 volatile compounds were identified in FD, IRFD and HAD samples, respectively. FD and IRFD were relatively more effective than HAD for better retention of volatile compounds ofRosa rugoseflower. E-nose analysis also exhibited similar flavor properties in FD and IRFD samples. The molecular structure properties of FD and IRFD samples measured by FTIR spectroscopy were also similar. As for nutritional properties, HAD dramatically (P< 0.05) reduced the nutritional values ofR. rugosaflower after drying. The content of vitamin C (from 14.83 to 12.15 mg 100 g(-1)), flavonoids (from 478.00 to 333.33 mg 100 g(-1)) and anthocyanins (from 220.70 to 196.90 mg 100 g(-1)) inR. rugosaflower is well retained by IRFD and no significant difference (P< 0.05) was observed between FD and IRFD samples. CONCLUSION IRFD was found to be effective in retaining the aroma, structure and nutrition ofR. rugosaflower, as well as demonstrating a lower energy consumption and shorter drying time.

To determine the effect of aromatherapy with rose and lavender on the patient outcomes after open‐heart surgery (OHS). In the clinical trial, patients were randomized to four groups. One group received routine care, the placebo group received a cotton swab soaked in water and the other two groups received either a cotton swab containing three drops of rose or lavender essence (0.2 ml). A total of 160 patients were randomized into four groups. Intergroup anxiety was not significantly different; however, the reciprocal time‐group effect was significant among the four groups. The extubation time was significant among the four groups which related to rose essence group compared with the control group (p < .001) and placebo group (p = .029). The surgical site pain was significant in the rose essence and lavender groups compared to the control group. Aromatherapy can reduce extubation time, surgical site pain severity, and anxiety in patients undergoing OHS

Empathy and related concepts such as sympathy and compassion are considered fundamental to mental health nurses' work with consumers. However, there is often little consensus on the relationship between these interpersonal interaction factors and their similarities and differences. In this paper, these three concepts are discussed. Theoretical frameworks of empathy, sympathy, and compassion are presented with a social psychological model of empathy focused upon. From this, discussion is undertaken of how the mental health nursing process may be explained by such frameworks, as well as what unique aspects of the nursing relationship need to be considered. It is contended that precise definitions and understandings of empathy, sympathy, and compassion are vital, and the use of models allows researchers to consider where gaps are in current knowledge, and to identify what might be important to consider from a nurse education perspective.

Introduction This study was intended to assess the efficacy and safety of a rosehip seed oil (RHO) extract in the prevention and treatment of skin lesions in the hands of patients with type 1 diabetes mellitus (T1DM) caused by finger prick blood glucose monitoring. Patients and method A prospective, randomized, controlled, open-label, rater-blinded trial in patients aged 6-17 years with T1DM and intensive blood glucose control (≥7 finger pricks daily) for 12 days. Three main variables (erythema, skin thickening, and loss of skin integrity) were assessed using a scale ranging from 0 (absent) to 3 (severe involvement). The study was approved by the ethics committee of the hospital. Results Sixty-eight children, and thus 136 hands, were included; 80 hands received rosehip seed oil and 56 hands acted as controls. Baseline characteristics of both groups were similar, with 76.3% and 78.6% of the hands respectively showing skin lesions at study start. Median final global assessment was 0.10 (0.03; 0.30) in the group that received rosehip seed oil and 0.06 (0.00; 0.23) in the control group. A statistically significant improvement in global assessment was found in the control group (P=0.049). No significant differences were found when the medians of the other main variables were compared. No adverse effects were recorded. Conclusion A high prevalence of skin lesions secondary to finger prick glucose monitoring, most of them mild lesions, was found at study start. Treatment with rosehip seed oil was safe and was not effective for improving skin lesions.

Background Attention-deficit/hyperactivity disorder (ADHD) is the most common behavioral disorder in childhood and adolescence. A number of these patients do not respond to the current pharmacological treatments and there may also be drug side effects. This study aims to determine the efficacy and safety of two herbal medicine products, including Rosa canina L. (RC) and a polyherbal formulation (PHF) syrup, on the clinical manifestations of ADHD in children and adolescents. Methods Ninety ADHD patients based on DSM-5 diagnostic criteria will be randomly assigned equally into three groups: (1) RC syrup + methylphenidate (MP), (2) PHF syrup + MP, and (3) placebo + MP according to the inclusion criteria (30 subjects in each group). The syrup dosage is 5cc every 8 h, and MP will have a stabilized dose for 8 weeks during the study. Moreover, Conner’s questionnaires will be completed by the teacher and parents before the intervention and then every 4 weeks. Also, the Child Symptom Inventory-fourth edition (CSI-4) and temperament questionnaires will be completed before the intervention and every 4 weeks until 2 months. Discussion This trial is the first experiment to determine the effects of RC and PHF syrups on the clinical manifestations of ADHD in children and adolescents. Our findings provide new insight into the effect of these herbal products on the clinical manifestations of ADHD. Trial registration Iranian Registry of Clinical Trials IRCT20190923044855N1.

This study aims to investigate the vasorelaxation effects of a Rosa centifolia petal extract (ROSE CRYSTA®-70: ROSE-70) on the isolated aorta and the protective effect of ROSE-70 on human umbilical vein endothelial cells (HUVECs) dysfunction. ROSE-70 inhibited phenylephrine (PE) -induced contraction in an endothelium-dependent and endothelium-independent manner; however, this relaxation was lower in the endothelium-denuded aorta. ROSE-70-induced relaxation was attenuated by L-N

This paper presents an implementation of RoSA, a Robot System Assistant, for safe and intuitive human-machine interaction. The interaction modalities were chosen and previously reviewed using a Wizard of Oz study emphasizing a strong propensity for speech and pointing gestures. Based on these findings, we design and implement a new multi-modal system for contactless human-machine interaction based on speech, facial, and gesture recognition. We evaluate our proposed system in an extensive study with multiple subjects to examine the user experience and interaction efficiency. It reports that our method achieves similar usability scores compared to the entirely human remote-controlled robot interaction in our Wizard of Oz study. Furthermore, our framework’s implementation is based on the Robot Operating System (ROS), allowing modularity and extendability for our multi-device and multi-user method.

The aim of this study was to investigate the effect of a polysaccharide from Rosa rugosa Thunb. on human cervical cancer cells (HCCCs) and the underlying mechanism. Here, a novel Rosa rugosa polysaccharide, named as RRP, was purified from Rosa rugosa petals. RRP consisted of glucose, galacturonic acid, mannose, rhamnose, galactose, arabinose, xylose, and glucuronic acid (molar ratio: 7.78:7.59:4.23:3.22:3.15:1.65:1.00), with Mw of 327.92 kDa. RRP remarkably inhibited cell proliferation, migration, and cell cycle arrest in HeLa and SiHa cells. Furthermore, RRP induced apoptosis by activating the caspase family of proteins and mediating the reactive oxygen species (ROS)-mediated mitochondrial pathway. In addition, RRP was found to dose-dependently induce autophagy, which occurred prior to apoptosis. RRP also primarily induced autophagy-mediated apoptosis in HCCCs via the PI3K/AKT/mTOR pathway. Thus, RRP might serve as a legitimate therapeutic drug candidates against human cervical cancer.

Arsenic poisoning is a geochemical disease that seriously endangers human health. The liver is one of the important target organs for arsenic poisoning, several studies have shown that oxidative stress plays an important role in arsenic-induced liver damage. However, the specific mechanism of arsenic-induced oxidative stress has not yet been fully elucidated, and currently, there are no effective intervention measures for the prevention and treatment of arsenic-induced liver damage. In this study, the effect of the Nrf2/GPX4 signaling pathway and oxidative stress in the arsenic-induced liver damage was first evaluated. The results show that arsenic can activate the Nrf2/GPX4 signaling pathway and increase the oxidative stress, which in turn promotes arsenic-induced liver damage in MIHA cells. Moreover, when we applied the Nrf2 inhibitor, the promoting effect of arsenic on liver damage was alleviated by inhibiting the activation of the Nrf2/GPX4 signaling pathway. Subsequently, the Rosa roxburghii Tratt [Rosaceae] (RRT) intervention experiments in cells and arsenic poisoning population were designed. The results revealed that RRT can inhibit Nrf2/GPX4 signaling pathway to reduce oxidative stress, thereby alleviates arsenic-induced liver damage. This study provides some limited evidence that arsenite can activate Nrf2/GPX4 signaling pathway to induce oxidative stress, which in turn promotes arsenic-induced liver damage in MIHA cells. The second major finding was that Kaji-ichigoside F1 may be a potential bioactive compound of RRT, which can inhibit Nrf2/GPX4 signaling pathway to reduce oxidative stress, thereby alleviates arsenic-induced liver damage. Our study will contribute to a deeper understanding of the mechanisms in arsenic-induced liver damage, these findings will identify a possible natural medicinal food dual-purpose fruit, RRT, as a more effective prevention and control strategies for arsenic poisoning.

A new robotic platform (ROSA® Knee system, Zimmer Biomet, Warsaw, Indiana) for total knee arthroplasty (TKA) has been created to increase precision of bony resections and knee balancing while maintaining surgeon autonomy. Our aim is to discuss: (1) the background of robotic technology in orthopedics, (2) current literature and potential benefits of the ROSA® Knee system, and the (3) optimal surgical technique for this specific robotic TKA platform. Early literature regarding this robotic system is promising as studies have shown precision of its bony resections, accuracy of overall limb alignment, and low early revision rates. There is a need for continued research on clinical outcomes using this platform, and the intention is to provide a review with insight into the potential advantages of robotics and the ideal surgical technique for successful use of this system.

Among respiratory complications, cough is an important defensive pulmonary reflex that removes fluids, irritants or foreign substances from the respiratory tract. Rosa damascene Mill, petal extract is a traditional medicine and reported to use in the management of cough. In the present study rose petals extract samples were used to prepare natural antitussive cough syrups containing ivy leaf extract to observe synergistic effect of rose water in managing coughing in rats. Four cough formulations (A1, A2, A3 and A4) were prepared. The antitussive activity was observed at three dosage levels; 5ml, 10ml and 15ml. Cough was induced by the standard procedure using sulfur dioxide gas and ammonia. The antitussive activity was recorded by observing the coughing bouts. The result indicated that all formulations had a good effect on cough reduction at 90min but comparing the effect of formulations in all doses formulations, A2 followed by A3 and A4 at 30 minute time interval which is good in comparison with standard Diphenhydramine HCL and Dextromethorphan HBr 10ml in sulfur dioxide gas and ammonia induced cough. Hence, the results of the present study indicated the synergistic effect of rose water in the management of cough ailments.

Traditional fermented Rosa (TFR) is a typical food and medical product among the Dali Bai people, and its popularity is growing. A few studies have looked into TFR's medicinal advantages, linked germplasm resources, traditional processing procedures, and functional food qualities. Our goal was to look into Rosa's traditional processing, examine the dominant strains in TFR, and prove how these strains affected antioxidant and tyrosinase inhibitory activities. We used a snowball selection strategy to pick 371 informants for a semi-structured interview, supplemented with direct observations and sample collection. A microbial strain was isolated and identified from a TFR sample collected in the field. We synthesized TFR in the lab using the traditional way. Both of 2, 2-diphenyl-1 picrylhydrazyl (DPPH) free radical scavenging and tyrosinase inhibitory properties of the fermented solution of Rosa 'Dianhong' have been tested in this study. Altogether 15 species belonging to the genus Rosa, which are utilized in herbal medicine and fermented foods. Rosa 'Dianhong' was the Bai community's principal species with considerable cultural value and consumption. Raw Rosa petals included 15 major flavonoids and phenols, which were identified as TFR's active components. TFR-1 was discovered to be the dominating microbial strain in TFR, increasing total phenolic and flavonoid content in the fermented solution of Rosa 'Dianhong' by 0.45 mg GAE/ml and 0.60 mg RE/ml, respectively, after 30 days. TFR-1 also exhibited promising activity in terms of DPPH free radical scavenging and tyrosinase inhibition. TFR showed potent antioxidant and free-radical scavenger properties and is beneficial in skincare and nutrition, according to the findings. TFR's medicinal and edible properties suggest that it could be used as a cosmetic or nutraceutical product.

Rosa roxburghii tratt (RRT), widely distributed in the southwest of China, is favored by consumers for its good taste and healthy functions. In this study, thirty-seven compounds of Rosa roxburghii Tratt (RRT) were identified and quantified by gas chromatography–olfactometry (G–O) and gas chromatography–mass spectrometry (GC–MS) analysis. Furthermore, ethyl 2-methylpropanoate, ethyl butanoate, ethyl 2-methylbutyrate, and ethyl hexanoate were present with much higher odor activity values (OAVs) than other compounds. The key notes were confirmed by omission tests. Possible interaction among key notes was investigated through odor intensity determination and sensory analysis. It showed fruity and woody notes had synergistic effects. Full factorial design was used to evaluate the notes contribution to the whole odor. One important finding is the major effect of order interactions, fruity note (X1) and woody note (X4) especially, emphasizing the existence of complex interactions occurring between odor notes. The interaction X1X4 was further investigated. The woody note has a positive effect when the fruity note is also in the mixture but tends to show a negative effect otherwise.

Purpose Although aromatherapy with damask rose can reduce anxiety and improve sleep quality in different conditions, no study has yet addressed its effects among operating room (OR) personnel. Considering the high level of workload among Iranian OR personnel during the COVID-19 pandemic which can affect their anxiety and sleep quality, this study evaluated the effects of damask rose aromatherapy on state anxiety and sleep quality among a population of Iranian OR personnel during the COVID-19 pandemic. Design A randomized, non-blinded, parallel-group controlled trial. Methods Eighty OR personnel were divided into the two groups of damask rose and placebo (paraffin oil) using the stratified randomization method. In the first aromatherapy session, the participants inhaled two drops of either damask rose oil or paraffin oil for 10 min at the beginning of their morning shift. Then, they attached an absorbent cloth napkin impregnated with 5 drops of products to the side of their pillow for 30 consecutive nights. The Spielberger state anxiety inventory (SAI) and the Pittsburgh sleep quality index (PSQI) were completed before random allocation (T1) and on the 31st day of the study (T3). Also, the SAI was completed 90 min after the end of the first aromatherapy session (T2). Findings The mean changes in the SAI score were significant compared to T1 both at T2 and T3 in favor of the damask rose group (P

The enrichment of commonly consumed foods with bioactive components might be helpful in promoting health and reducing the risk of disease, so the enrichment of probiotic fermented milk with vitamin C can be considered appropriate. The effect of vitamin C addition depends on the source of origin (rosehip, acerola and ascorbic acid in powder form) on the growth and survival of Lactobacillus rhamnosus and the quality of fermented milk on the 1st and 21st day of storage was analyzed. The pH, total acidity, vitamin C, syneresis, color, texture profile and numbers of bacterial cells in fermented milk were determined. The organoleptic evaluation was also performed. The degradation of vitamin C in milk was shown to depend on its source. The lowest reduction of vitamin C was determined in milk with rosehip. The least stable was vitamin C naturally found in control milk. The addition of rosehip and acerola decreased syneresis and lightness of milk color, increasing the yellow and red color proportion. In contrast, milk with ascorbic acid was the lightest during the whole experimental period and was characterized by a very soft gel. The growth of Lactobacillus rhamnosus during fermentation was most positively affected by the addition of rosehip. However, the best survival of Lactobacillus rhamnosus was demonstrated in milk with acerola. On the 21st day of storage, the number of L. rhamnosus cells in the control milk and the milk with vitamin C was >8 log cfu g−1, so these milks met the criterion of therapeutic minimum. According to the assessors, the taste and odor contributed by the addition of rosehip was the most intense of all the vitamin C sources used in the study.

Rosa × damascena Herrm., known as damask rose, is a bushy shrub that is found abundantly in Fars province, Iran. This species has been used in Iranian traditional practices for the treatment of abdominal pain and constipation, as gastrointestinal diseases. Brown sugar (Saccharum officinarum L.) has also shown laxative effects in pediatric patients with functional constipation.This study aimed to compare the effects of Polyethylene Glycol (PEG) and a syrup made of R. damascena and brown sugar on the treatment of functional constipation in children aged above 12 months.This double-blind randomized clinical trial was performed on 100 patients. One group received PEG and the other received an herbal syrup containing the decocted extract of 0.1 g R. damascena petals mixed with 0.85 g brown sugar per 1 mL. The patients were followed up for two and four weeks and their progresses were recorded.The cure rate was 100% in the R. damascena group and 91.7% in the control group. R. damascena and brown sugar syrup had an odds ratio of 1.09 in the treatment of functional constipation compared to PEG, but the difference was not statistically significant. The only adverse effect detected in the R. damascena group after four weeks was the bad taste of the medication that was too sweet. Nonetheless, this could be solved during the pharmaceutical processes.The R. damascena extract and brown sugar syrup can be used as an effective, safe, and inexpensive agent in the treatment of functional constipation.

Background: A few studies have demonstrated the association of poorer olfactory identification (OI) with poorer cognition in population-based cohorts. None of them considered the outcome associated with the inability to smell a certain odor. Objective: To verify the hypothesis that at least one specific odor is associated with incident cognitive decline among older adults. Methods: In the Shanghai Aging Study, a sub-cohort of 948 dementia-free participants who had baseline OI measurements were prospectively followed for 5 years. Results: An inability to smell peppermint (β = –0.44, p < 0.001), rose (β = –0.14, p = 0.040), or coffee (β = –0.37, p = 0.002) was inversely related to the annual rate of change in the Mini Mental State Examination score, and an inability to smell peppermint was associated with a higher risk for incident dementia (hazard ratio 2.67, 95% CI 1.44–4.96) after adjustment for confounders. Conclusion: Our study suggests that some odors, especially peppermint, might be considered as a potential predictor for dementia in older populations.

Eijitsu, the fruits of Rosa multiflora Thunberg, is a traditional Japanese natural medicine and used as purgatives. The active constituents were identified as flavonol glycosides, multiflorin A (MF), and multinoside A (MSA), but mechanism of the purgative action is still unknown. We hypothesized that the flavonol glycosides 1 and 2 may exhibit the purgative actions through modulating intestinal epithelial barrier function. Then, this study aimed to investigate their effects on intestinal epithelial barrier function and possible molecular mechanisms in human intestinal Caco-2 cells. MF and MSA decreased transepithelial electrical resistance and increased paracellular permeability of Caco-2 cell monolayers. Expression of claudins (CLDNs) involved in paracellular permeability of ions and low-molecular substances was significantly decreased by the treatment with MF or MSA. The compounds increased the ratio of N-cadherin/E-cadherin, expression of transforming growth factor-β and Slug, and phosphorylation level of Smad3, suggesting epithelial-mesenchymal transition activation, and epithelial-mesenchymal transition inhibition by transforming growth factor-β receptor kinase inhibitors completely recovered the decreased CLDNs expression caused by MF and MSA. Moreover, the increased paracellular permeability and the decreased CLDNs expression by the treatment with MF or MSA for 24 hours recovered to the same extent as the untreated group with the compounds by continuous culture in the growth medium alone for 48 hours. These results suggest that Eijitsu may be effective in preventing or relieving constipation symptoms, unless used chronically.

Background and objectives More men than women undergo kidney replacement therapy (KRT) despite a larger number of women being affected by CKD. The aim of this multinational European study was to explore whether there might be historic and geographic trends in sex-specific incidence and prevalence of various KRT modalities. Design, setting, participants, & measurements We assessed sex-specific differences in KRT incidence and prevalence using data from nine countries reporting to the European Renal Association–European Dialysis and Transplant Association (ERA-EDTA) Registry for at least 40 years, during the period 1965–2015. Sex distribution data were compared with the European general population (Eurostat). Statistical methodology included basic descriptive statistics, incidence and prevalence calculations per million population (pmp), as well as their male-to-female ratios. Analyses were stratified by age group and diabetic status. Results We analyzed data from 230,378 patients receiving KRT (38% women). For all KRT modalities, the incidence and prevalence rates were consistently higher in men than women. For example, the KRT incidence increased from 8 pmp in 1965–1974 to 98 pmp in 2005–2015 in women, whereas it rose from 12 to 173 pmp in men during the same period. Male-to-female ratios, calculated for incident and prevalent KRT patients, increased with age (range 1.2–2.4), showing consistency over decades and for individual countries, despite marked changes in primary kidney disease (diabetes more prevalent than glomerulonephritis in recent decades). The proportion of kidney transplants decreased less with age in incident and prevalent men compared with women on KRT. Stratified analysis of patients who were diabetic versus nondiabetic revealed that the male-to-female ratio was markedly higher for kidney transplantation in patients with diabetes. Conclusions Since the beginning of KRT programs reporting to the ERA-EDTA Registry since the 1960s, fewer women than men have received KRT. The relative difference between men and women initiating and undergoing KRT has remained consistent over the last five decades and in all studied countries.
