Novel coronavirus (COVID-19), a global threat whose source is not correctly yet known, was firstly recognised in the city of Wuhan, China, in December 2019. Now, this disease has been spread out to many countries in all over the world. In this paper, we solved a time delay fractional COVID-19 SEIR epidemic model via Caputo fractional derivatives using a predictor-corrector method. We provided numerical simulations to show the nature of the diseases for different classes. We derived existence of unique global solutions to the given time delay fractional differential equations (DFDEs) under a mild Lipschitz condition using properties of a weighted norm, Mittag-Leffler functions and the Banach fixed point theorem. For the graphical simulations, we used real numerical data based on a case study of Wuhan, China, to show the nature of the projected model with respect to time variable. We performed various plots for different values of time delay and fractional order. We observed that the proposed scheme is highly emphatic and easy to implementation for the system of DFDEs.

Unlabelled: Previous studies illustrated that two banana GA20 oxidase2 (MaGA20ox2) genes, and , are implicated in controlling banana growth and development; however, the biological function of each gene remains unknown. Ma04g15900 protein (termed MaGA20ox2f in this article) is the closest homolog to the Rice SD1 (encoded by 'green revolution gene', ) in the banana genome. The expression of is confined to leaves, peduncles, fruit peels, and pulp.

Background: YYD601 is a new dual delayed-release formulation of esomeprazole, developed to enhance plasma exposure and prolong the duration of acid suppression.
Purpose: This study aimed to evaluate the safety, pharmacokinetic (PK), and pharmacodynamic (PD) profiles of YYD601 20 mg following single and multiple oral administrations in healthy, fasting adult Koreans, and to compare these outcomes to those of the conventional esomeprazole 20 mg capsule.
Methods: A randomized, open-label, two-period crossover study was conducted in 28 participants, who were divided into two treatment groups: one group received YYD601 20 mg, and the other received conventional esomeprazole 20 mg, once daily for five consecutive days.

Background Self-medication is commonly practiced, especially among medical students, administrative staff, and faculty from preclinical and paraclinical departments, driven by accessibility, familiarity with medications, and perceived convenience. This study explored the incidence, patterns, and factors influencing self-medication within the Xavier University School of Medicine, Aruba, with a primary focus on medical students and administrative staff. The faculty included in the study were from preclinical and paraclinical departments such as anatomy, physiology, biochemistry, pathology, forensic medicine, microbiology, and community medicine.

Introduction: Toothbrushing, during which dental plaque is brushed off into the oral cavity, can increase the risk of aspiration pneumonia in older adults and intubated patients.
Methods: This study examined brushing methods to prevent the spread of bacteria in the oral cavity. Six participants who required assistance with brushing received toothbrushing from a dental hygienist.

Background: B-cell specific Moloney MLV insertion site-1 (Bmi-1) belongs to the polycomb group (PcG) gene and is a transcriptional suppressor to maintain appropriate gene expression patterns during development. To investigate whether the Bmi-1 gene has a corrective effect on bone senescence induced in Bmi-1 mice through regulating the bone microenvironment.
Methods: Littermate heterozygous male and female mice (Bmi-1) were used in this study.
