Abstract	The present work aims to study the photocatalytic properties of nanohybrids composed of silicon nanowires (SiNWs) decorated with PbS nanoparticles (NPs). The elaborated material was intended to be utilized in wastewater treatment. The SiNWs were elaborated from the Metal Assisted Chemical Etching route (MACE), while the PbS NPs were deposited at room temperature onto SiNWs using the pulsed laser deposition (PLD) technique. The influence of decorating SiNWs (having different lengths) with PbS-NPs on their structural, morphological, optoelectronic, and photocatalytic properties was scrutinized. PbS/SiNWs nanohybrids exhibited enhanced photocatalytic degradation towards Black Amido (BA) dye for 20 µm SiNWs length and 0.2% of BA volume concentration. These optimized conditions may insinuate that this nanocomposite-like structure is a promising efficient photocatalytic systems contender, cost-effective, and recyclable for organic compound purification from wastewaters.

Abstract	Animal body-size variation influences multiple processes in marine ecosystems, but habitat heterogeneity has prevented a comprehensive assessment of size across pelagic (midwater) and benthic (seabed) systems along anthropic gradients. In this work, we derive fish size indicators from 17,411 stereo baited-video deployments to test for differences between pelagic and benthic responses to remoteness from human pressures and effectiveness of marine protected areas (MPAs). From records of 823,849 individual fish, we report divergent responses between systems, with pelagic size structure more profoundly eroded near human markets than benthic size structure, signifying greater vulnerability of pelagic systems to human pressure. Effective protection of benthic size structure can be achieved through MPAs placed near markets, thereby contributing to benthic habitat restoration and the recovery of associated fishes. By contrast, recovery of the world's largest and most endangered fishes in pelagic systems requires the creation of highly protected areas in remote locations, including on the High Seas, where protection efforts lag.

Abstract	Background: Candida glabrata Aim: Using immunoinformatics approach to predict the most conserved and immunogenic B- and T-cell epitopes from the fructose bisphosphate aldolase (Fba1) protein of Result: The promising B-cell epitopes were AYFKEH, VDKESLYTK, and HVDKESLYTK, while the promising peptides which have high affinity to MHC I binding were AVHEALAPI, KYFKRMAAM, QTSNGGAAY, RMAAMNQWL, and YFKEHGEPL. Two peptides, LFSSHMLDL and YIRSIAPAY, were noted to have the highest affinity to MHC class II that interact with 9 alleles. The molecular docking revealed that the epitopes QTSNGGAAY and LFSSHMLDL have the lowest binding energy to MHC molecules. Conclusion: The epitope-based vaccines predicted by using immunoinformatics tools have remarkable advantages over the conventional vaccines in that they are more specific, less time consuming, safe, less allergic, and more antigenic. Further in vivo and in vitro experiments are needed to prove the effectiveness of the best candidate's epitopes (QTSNGGAAY and LFSSHMLDL). To the best of our knowledge, this is the first study that has predicted B- and T-cell epitopes from the Fba1 protein by using in silico tools in order to design an effective epitope-based vaccine against

Abstract	Purpose: Epilepsy type, whether focal or generalised, is important in deciding anti-seizure medication (ASM). In resource-limited settings, investigations are usually not available, so a clinical separation is required. We used a naïve Bayes approach to devise an algorithm to do this, and compared its accuracy with algorithms devised by five other machine learning methods. Methods: We used data on 28 clinical variables from 503 patients attending an epilepsy clinic in India with defined epilepsy type, as determined by an epileptologist with access to clinical, imaging, and EEG data. We adopted a machine learning approach to select the most relevant variables based on mutual information, to train the model on part of the data, and then to evaluate it on the remaining data (testing set). We used a naïve Bayes approach and compared the results in the testing set with those obtained by several other machine learning algorithms by measuring sensitivity, specificity, accuracy, area under the curve, and Cohen's kappa. Results: The six machine learning methods produced broadly similar results. The best naïve Bayes algorithm contained eleven variables, and its accuracy was 92.2% in determining epilepsy type (sensitivity 92.0%, specificity 92.7%). An algorithm incorporating the best eight of these variables was only slightly less accurate - 91.0% (sensitivity 89.6%, and specificity 95.1%) - and easier for clinicians to use. Conclusion: A clinical algorithm with eight variables is effective and accurate at separating focal from generalised epilepsy. It should be useful in resource-limited settings, by epilepsy-inexperienced doctors, to help determine epilepsy type and therefore optimal ASMs for individual patients, without the need for EEG or neuroimaging.

Abstract	Heterocyclic chemistry has provided an inexhaustible source of pharmaceutical molecules. Heterocyclic compounds such as benzothiazole moieties and its derivatives area substantial class of compounds in pharmaceutical chemistry and exhibited therapeutic capabilities, such as antitumor, anticancer, antioxidant, antidiabetic, antiviral, antimicrobial, antimalarial, anthelmintic and other activities. Besides, some antibiotics such as penicillin and cephalosporin have heterocyclic moiety. The growing prevalence of multi-drug resistant pathogens represents serious global concern,which requires the development of new antimicrobial drugs. Moreover, the emergence of pandemic SARS-CoV-2 causing Covid-19 disease and all these health dilemmas urge the scientific community to examine the possible antimicrobial and antiviral capacities of some bioactive benzothiazole derivatives against these severe causative agents.This mini-review highlights some recent scientific literature on different benzothiazole molecules and their derivatives. It turns out that, there are numerous synthesized benzothiazole derivatives which exhibited different mode of actions against microorganisms or viruses and accordingly suggested them as an active candidate in the discovery of new antimicrobial or antiviral agents for clinical development. The recommended bioactive benzothiazole derivatives mentioned in the current study are mainly Schiff bases, azo dyes and metal complexes benzothiazole derivatives; the starting material for most of these derivatives are 2-aminobenzothiazole although careful pharmaceutical studies should be conducted to ensure the safety and efficacy of these bioactive synthesized molecules as an antimicrobial or antiviral drug in the future.

Abstract	This investigation deals with synthesis of some novel chemo sensors for identifying cations in drinking water and agricultural crops. This takes place via interaction of 2,5-dioxo-1,2,3,4-tertrahydropyridine-3-carbonitrile (3) and 2-thioxo-5-oxo-1,2,3,4-tertrahydropyridine-3-carbonitrile (4) with CuII and CoII. The novel compounds' structures have been examined using spectrum data (IR, 1H NMR, 13C NMR, and MS) as well as elemental and physical studies. Complexation behaviors of Compounds 3 and 4 as organic ligands were predicted, discussed, and calculated via Density-Functional Theory (DFT) and Colorimetric investigation. The newly synthesized receptors 3 and 4 showed selective colormetric sensing capability for some cations by color shifting from colorless to pale violet in a nearby ideal aqueous solution enabling naked eye identification and quantitative determination of cooper (CuII) and cobalt (CoII) metal ion.

Abstract	Background: Missed Abortion is non-viable intrauterine pregnancy with either an empty gestational sac or a gestational sac contains an embryo without fetal heart activity. Objectives: The aim of this study was to compare effect of misoprostol with clomiphene citrate, misoprostol with letrozole and misoprostol alone in terminating first trimester missed abortion. Patients and methods: This randomized clinical trial was included patients with missed abortion attending to our outpatient clinic at South Valley University Hospital, Department of Obstetrics and Gynecology. Fifteen patients were excluded during the follow-up period; hence, 37 patients per group were included in the final analysis. They divided into three groups: Interventional group (A): received 5mg letrozole Group (B): received 100 mg clomiphene citrate and Group (C): Control group received calcium carbonate . Then all patients received two doses of 800 microgram misoprostol orally. Results: As regard outcome among the three studied groups. The results showed that 21.6% cases in group (A) showed failure in management with six cases needed surgical evacuation and two cases completed treatment on misoprostol, 32.4% cases in group(B) showed failure in management with ten cases needed surgical evacuation and two cases completed treatment on misoprostol and 37.8% cases in group(C) showed failure in management with ten cases needed surgical evacuation and four cases completed treatment on misoprostol. Conclusion: Letrozole pre-treatment with misoprostol increases efficacy of misoprostol in induction of complete abortion of non-viable first trimester pregnancy with no evident side effects.
