In this study, superhydrophilic polyester textiles through atmospheric pressure plasma treatment, targeting their use in oil-water mixture separation was developed. The effect of fabric treatment and grammage variations—79, 103, and 125 g m−2—on the efficiency of separation, flux rates, and overall performance of the separation column was evaluated. The surface properties of the fabricated polyester fabrics were evaluated using scanning electron microscopy and energy-dispersive X-ray spectroscopy to analyze their topographical and elemental composition. These analyses indicate APP treatment creates surface micropits and evenly distributes active oxygen, enhancing polyester's hydrophilicity without altering its elemental makeup. The investigation further explored the antifouling capabilities and durability of both the modified and unmodified textiles. Remarkably, the research revealed that utilizing a dual-layer arrangement of the modified textile, possessing a grammage of 125 g m−2, resulted in a flux recovery ratio of 98.66 %. Additionally, the application of a quintuple-layer structure of the modified fabric markedly augmented the separation efficacy to an excess of 99.90 %. Impressively, this high level of efficiency was maintained at 92.20 % even after five usage cycles, a testament to the increased hydrophilicity imparted by the atmospheric pressure plasma processing. Therefore, atmospheric pressure plasma-treated polyester fabrics have shown a promising behavior in the field of oil-water mixture separatrtion.

Background: real-time polymerase chain reaction (RT-PCR) of nasal/oropharyngeal samples is the gold standard in detecting SARS-CoV-2 infection, however, it has a long turnaround time. Objectives: To meet the growing epidemic demand, we evaluated the performance of rapid SARS-CoV-2 antigen tests in detecting COVID-19 infection compared to RT-PCR. Patients and Methods: a cross-sectional study involving adults suspected to have mild or moderate COVID-19 infection severity scores over 6 months from 1/10/2021 to 1/4/2022. Results: from 186 patients assessed, 88(47.3%) males and 98 (52.7%) females with a mean age of 52.55 ± 20.15 years, and a mean disease duration of 13.1± 4.5 days. 57(30.6%) cases of RT-PCR were positive and 129(69.4%) cases were negative. Meanwhile, in rapid antigen tests, 49(26.34%) cases were positive and 137(73.35%) cases were negative. The receiver operator characteristic (ROC) curve predicts the performance of rapid antigen tests revealing an overall agreement with the RT-PCR results, with 85% sensitivity (95% CI, 73.43% - 92.90 %), 98.54% specificity (95% CI, 94.83% - 99.82%), 96.23% PPV (95% CI, 86.52% - 99.02%), 93.75% NPV (95% CI= 89.14% - 96.48%), 94.42% accuracy (95% CI, 90.23% - 97.18%), and with 0.918 the area under the curve. Conclusion: Although RT-PCR is still the gold standard for detecting SARS-CoV-2 infections, the rapid SARS-CoV-2 antigen test offers good sensitivity, specificity, PPV, NPV, and a significantly short turnaround time. As a result, it has great clinical utility as a primary frontline test for detecting infected patients in an emergency setting.

Green assessment of analytical procedures has become an environmental obligation in equivalence to their International Council of Harmonization analytical validation obligation. Worldwide awareness of our planet and ecological hazards have raised the shades of green and sustainable chemistry in pure or formulated API assays. The Green Analytical Procedure Index (GAPI) is instant five pentagrams for evaluating the greenness of each step in the developed analytical procedure, in discriminative colors: green, yellow, and red. In the present study, GAPI is applied to assess three novel direct analytical methods: spectrophotometric, fluorimetric, and high-performance thin-layer chromatography (HPTLC) for remdesivir (RDV) quantitation, both in bulk and pharmaceutical vials. Furthermore, a comparative green level calculated GAPI study has been assembled for the proposed methods versus the previously reported methods, for RDV assay, of similar techniques. Spectrophotometric direct Amax method at 240 nm, fluorimetric emission at 404 nm upon excitation at 275 nm as well as the HPTLC densitometric measurement using ethanol and distilled water (7:3, v/v) as mobile phase, all three methodologies are developed, optimized, and fully validated for RDV quantitation. They have been applied to assay RDV pharmaceutical vials and results are compared together with a one-way ANOVA test. Satisfactory recoveries and nano-level sensitivities in addition to the least standard deviations encourage the use of developed methods for routine analysis in quality control laboratories. Their promising greenness profile satisfies the beliefs of ecological sustainability of Green Agenda 2030.

Abstract Background Chylolymphatic cysts are benign pathology in lymphatic vessels due to obstruction in the lymphatic system. Their incidence is still unknown. However, they account for approximately 3 to 9% of all pediatric lymphangiomas. Most of these lesions are asymptomatic and are discovered accidentally. They can be presented with nonspecific abdominal pain, vomiting, and changes in bowel habits. Rarely, chylolymphatic cysts can as intestinal obstruction, volvulus or even torsion. Case presentation A 3-month-old male presented to our unit with manifestations of acute intestinal obstruction. Abdominal examination revealed signs of generalized peritonitis and intestinal obstruction. Abdominal ultrasound revealed minimal turbid intraperitoneal collections and no motility of bowel loops. Plain erect abdominal radiograph revealed multiple small bowel air fluid levels. Abdominal exploration revealed a large chylolymphatic cyst causing acute intestinal obstruction. Excision of the cysts was done with preservation of adjacent bowel loop. The patient was discharged in good health on the 6th day postoperative. A chylolymphatic cyst with a diameter of 5 cm was identified by histological investigation. Conclusions Most chylolymphatic cysts in infants are asymptomatic, but they can cause fatal complications such as intestinal obstruction, volvulus, or even torsion.

Abstract Background Acute gastroenteritis (AGE) in children represents a health problem. Besides common enteric viruses such as rotavirus and adenovirus, new viruses such as cosavirus, salivirus, and bufavirus may be associated with AGE. The objective of the study was to detect cosavirus, salivirus, and bufavirus viruses in children below 5 years with acute gastroenteritis by the use of real-time polymerase chain reaction (PCR) besides detection of rotavirus and adenovirus by enzyme-linked immunosorbent assay (ELISA). Method The study included 150 children ≤ 5 years with community-acquired diarrhea. Stool samples from children were subjected for the detection of rotavirus and adenovirus antigens by ELISA and for detection of buvavirus, salivirus, and cosavirus by real-time PCR. Results The commonest virus detected in the stool samples of children with AGE was rotavirus 31.3% followed by adenovirus 24%. Among the new viruses studied, salivirus was detected in six samples (4.0%), buvavirus was detected in four samples (2.7%), and cosavirus was detected in two samples (1.3%). The mixed rotavirus detection with studied viruses was 23.4% for adenovirus, 4.3% for calicivirus, and 2.1% for bocavirus, and none of the detected cosavirus was associated with rotavirus. In the studied children, at least one of the new viruses was detected in ten children (6.7%). Buvavirus, salivirus, and cosavirus were detected as a single virus (0.7%) in the children with acute gastroenteritis and buvavirus was detected with cosavirus without other viruses in one sample (0.7%). Conclusion The study reports the occurrence of buvavirus, cosavirus, and salivirus in the pediatric patients with community-acquired acute gastroenteritis. There was a high prevalence of rotavirus and adenovirus antigens in those patients with low positivity for buvavirus, cosavirus, and salivirus viruses. There is a need for a large cohort study to study the prevalence of buvavirus, cosavirus, and salivirus in pediatrics with acute gastroenteritis and to validate their association with the disease.

Abstract Background Multi-parametric magnetic resonance imaging may improve the detection of prostate cancer. The aim of this work is to compare between PI-RADS 3–5 and PI-RADS 4–5 as a threshold for targeted prostatic biopsy. Methods This is a prospective clinical study that included 40 biopsy-naïve patients referred for prostate biopsy. Patients underwent prebiopsy multi-parametric (mp-MRI), followed by 12-core transrectal ultrasound-guided systematic biopsy and cognitive MRI/TRUS fusion targeted biopsy from each detected lesion. The primary endpoint was to assess the diagnostic accuracy of the PI-RAD 3–4 versus PI-RADS 4–5 lesion by mpMRI for prostate cancer detection in biopsy-naive men. Results The overall prostate cancer detection rate and the clinically significant cancer detection rate were 42.5% and 35%, respectively. Targeted biopsies from PI-RADS 3–5 lesions showed a sensitivity of 100%, specificity of 44%, positive predictive value of 51.7%, and negative predictive value of 100%. Restricting targeted biopsies to PI-RADS 4–5 lesions resulted in a decrease in sensitivity and negative predictive value to 73.3% and 86.2%, respectively, while specificity and positive predictive value were increased to 100% for both parameters which was statistically significant (P value
