Ultrastructural imaging biomarkers in diabetic macular edema: A major review.

Diabetic macular edema (DME) is a vision-threatening complication of diabetic retinopathy and causes significant morbidity in patients. Anti-vascular endothelial growth factor (VEGF) agents are the mainstay of treatment for DME, with steroid implants being used for the treatment of anti-VEGF resistant eyes. Over the years, several classification systems have been devised to describe the patterns of DME using optical coherence tomography (OCT).

Immunoinformatics-driven design and computational analysis of a multiepitope vaccine targeting uropathogenic .

Unlabelled: Urinary tract infections (UTIs), largely caused by uropathogenic (UPEC), are increasingly resistant to antibiotics and frequently recur. Using immunoinformatics, we designed a multiepitope peptide vaccine targeting UPEC virulence factors, including iron acquisition systems and adhesins. The construct features 12 cytotoxic T lymphocyte epitopes, six helper T lymphocyte epitopes, and six B-cell epitopes,and isoptimized for high antigenicity, immunogenicity, nontoxic, and low allergenic potential.

Screening Asian Medicinal Plants for SARS-CoV-2 Inhibitors: A Computational Approach.

This work aimed to evaluate the antiviral potential of compounds from Asian medicinal plants against SARS-CoV-2's main protease and spike glycoprotein, identifying dual inhibitors from these plants that target both proteins through advanced virtual screening, molecular dynamics simulations, and pharmacophore analysis. An in-house library of 335 antiviral natural products was prepared from the selected medicinal plants. Following the virtual screening of this library against the main protease and spike glycoprotein, top compounds were subjected to downstream analysis for evaluating druggability potential and toxicity analysis.

Evaluation of the mindray CL900i CLIA HIV Ag/Ab combo assay for sensitive and specific HIV screening compared to established methods.

Architect-HIV Ag/Ab combo chemiluminescence assay is globally recognized for its sensitivity but has a notable false-positive rate. In this study, we aim to evaluate the performance of a new cost-effective screening alternative, the chemiluminescence Ag/Ab combo assay (CL-900i-HIV) from Mindray, China. We selected 195 archived samples categorized according to the INNO-LIA™ HIV I/II, the gold standard confirmatory assay.

Improving Laryngeal Procedure Workflow: Moving From the Operating Room to the Outpatient Setting.

Objectives: Laryngology disease burden is growing while theater capacity is falling. Over half a million patients are waiting for ENT care in England alone (1). The demand for laryngology services has continued to grow significantly, particularly post-COVID (2).

Development and optimization of a sustainable polyoxometalate-kaolinite-based catalyst for efficient desulfurization of model and real fuel using Box-Behnken design.

The oxidative desulfurization of dibenzothiophene in model and real fuel has been investigated by developing an environmentally sustainable catalyst HSiWO@f-kaolinite. The catalyst was synthesized by modifying kaolinite clay with (3-aminopropyl)triethoxysilane (f-kaolinite) followed by immobilizing silicotungstic acid hydrate (HSiWO) onto its surface. The successful synthesis of the catalyst was characterized by Fourier transform infrared spectroscopy, Raman spectroscopy, UV-visible spectroscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, and scanning electron microscopy.

Optimum feature selection for classification of PD signals produced by multiple insulation defects in electric motors.

Partial discharges (PD) are initiated in electrical equipment during various points of the equipment's lifecycle. The intensity of PD defects rises continuously with time, which can lead to insulation degradation and reduced operational life of the electrical equipment. The optimum feature selection of PD signals captured, from different insulation defects, can enhance the classification accuracy of PD defects and facilitate better visualization of PD parameters for electric motor (EM) insulation monitoring and diagnostics.

Elucidating the bioremediation potential of laccase and peroxidase enzymes from Bacillus ligniniphilus L1 in antibiotic degradation: A computationally guided study.

This study showcased the antibiotic degradation abilities of laccase and catalase-peroxidase from Bacillus ligniniphilus L1, an extremophile, against 18 common antibiotics using computationally guided approach. Molecular docking and simulation identified six enzyme-antibiotic complexes for laccase and four for catalase-peroxidase, demonstrating significant binding affinity and stability. Enzyme activity assays corroborated computational results, indicating both enzymes could degrade all tested antibiotics with varying efficiencies.

Evaluation of techno-economic design andimplementation of solar-wind hybrid microgridsystem for a small community.

Pakistan is faces significant challenges in meeting its energy demand and consumption needs for consumers. This country's energy production from primary sources such as petroleum and natural gasses is incompetent in fuel-use and hence unable to meet feasibility cost. With an increasing population, Pakistan's energy consumption per capita has been steadily rising.

Core outcome sets for trials of interventions to prevent and to treat multimorbidity in adults in low and middle-income countries: the COSMOS study.

Introduction: The burden of multimorbidity is recognised increasingly in low- and middle-income countries (LMICs), creating a strong emphasis on the need for effective evidence-based interventions. Core outcome sets (COS) appropriate for the study of multimorbidity in LMICs do not presently exist. These are required to standardise reporting and contribute to a consistent and cohesive evidence-base to inform policy and practice.

Uncovering chikungunya virus-encoded miRNAs and host-specific targeted genes associated with antiviral immune responses: an integrated bioinformatics approach.

Chikungunya virus (CHIKV) is a single-stranded RNA virus belonging to the genus Alphavirus and is responsible for causing Chikungunya fever, a type of arboviral fever. Despite extensive research, the pathogenic mechanism of CHIKV within host cells remains unclear. In this study, an in-silico approach was used to predict that CHIKV produces micro-RNAs that target host-specific genes associated with host cellular regulatory pathways.

The Practical Management of Rhinitis in Athletes.

Objective: Exercise-induced rhinitis (EIR) is a poorly understood condition that can have a massive impact within elite sport. This was epitomized in 2019 when British cyclist and Tour de France winner Chris Froome lost control of his bike at 37 mph while wiping his nose, resulting in an admission to intensive care. We aim to produce a comprehensive resource to guide the assessment and management of rhinitis in athletes.
