Intravital two-photon microscopy of the native mouse thymus.

The thymus, a key organ in the adaptive immune system, is sensitive to a variety of insults including cytotoxic preconditioning, which leads to atrophy, compression of the blood vascular system, and alterations in hemodynamics. Although the thymus has innate regenerative capabilities, the production of T cells relies on the trafficking of lymphoid progenitors from the bone marrow through the altered thymic blood vascular system. Our understanding of thymic blood vascular hemodynamics is limited due to technical challenges associated with accessing the native thymus in live mice.

Determination of vitamin c in raw fruit and vegetable homogenates: dietary exposure and health effects of excess intake in adults and children.

Objective: The aim of the study was to determine Vitamin C content in some fruits and vegetables (FAV) including apple, banana, orange, pineapple, watermelon, carrot and cucumber, sold in the local markets in Awka, Anambra State, Nigeria as well as Vitamin C content in two-component and three-component homogenates FAV. The work was also designed to investigate the dietary exposure and health effects of excess vitamin C intake in adults and children.

Material And Methods: Vitamin C as total ascorbic acid (AA) after reduction of dehydroascorbic acid was analyzed using both titrimetric and spectrophotometric methods.

Clinical profile and Predictors of Outcomes of Hospitalized Patients with Laboratory-Confirmed Severe Acute Respiratory Syndrome Coronavirus 2 in Nigeria: A Retrospective Analysis of 13 High Burden States in Nigeria.

Background: The majority of global COVID deaths have occurred in developed countries. Not much is known about the clinical outcomes for the patients admitted with COVID in Nigeria. We thus described the clinical characteristics, outcomes, and predictors of outcomes of hospitalized Nigerian COVID-19 patients.

Clinical instructors' Motivational roles and perceived effect on absenteeism among student nurses in a tertiary hospital, Benin-City, Nigeria.

Background: Absenteeism is a situation whereby students absence themselves from clinical posting without good reason, this incidence among student nurses contributed a significant problem that if not addressed will adversely affect the quality of nursing care; therefore, motivation of student during clinical posting found to be an important ingredient needed in eradicating absenteeism. Consequently, this study aims to determine the reasons why student nurses absenting themselves from clinical posting, its effect and how clinical instructor can motivate student nurses since they are the first role models and have a significant impact in their skill development.

Materials And Methods: A descriptive, quantitative design was used to elicit the information from a sample of 80 nurses and 80 students' nurses.

HIV care continuum outcomes of pregnant women living with HIV with and without depression.

Women living with HIV (WLWH) suffer from poor viral suppression and retention postpartum. The effect of perinatal depression on care continuum outcomes during pregnancy and postpartum is unknown. We performed a retrospective cohort analysis using HIV surveillance data of pregnant WLWH enrolled in perinatal case management in Philadelphia and evaluated the association between possible or definite depression with four outcomes: viral suppression at delivery, care engagement within three months postpartum, retention and viral suppression at one-year postpartum.
