Epidemiology of Angina Bullosa Hemorrhagica: A Retrospective study.

Introduction: Angina Bullosa Hemorrhagica (ABH) is a rare condition characterized by hemorrhagic blisters and is often asymptomatic. These lesions appear more commonly in the oral cavity and oropharynx and are often misdiagnosed. A retrospective cross-sectional study was performed in clinically confirmed cases of ABH to study its epidemiology, etiology and presentation in a tertiary care hospital in Southern Asia.

A Comprehensive Review of the Diversity of Fungal Secondary Metabolites and Their Emerging Applications in Healthcare and Environment.

Fungi and their natural products, like secondary metabolites, have gained a huge demand in the last decade due to their increasing applications in healthcare, environmental cleanup, and biotechnology-based industries. The fungi produce these secondary metabolites (SMs) during the different phases of their growth, which are categorized into terpenoids, alkaloids, polyketides, and non-ribosomal peptides. These SMs exhibit significant biological activity, which contributes to the formulation of novel pharmaceuticals, biopesticides, and environmental bioremediation agents.

Microglia modulate the cerebrovascular reactivity through ectonucleotidase CD39.

Microglia and the border-associated macrophages contribute to the modulation of cerebral blood flow, but the mechanisms have remained uncertain. Here, we show that microglia regulate the cerebral blood flow baseline and the responses to whisker stimulation or intra-cisternal magna injection of adenosine triphosphate, but not intra-cisternal magna injection of adenosine in mice model. Notably, microglia repopulation corrects these cerebral blood flow anomalies.

Regional and institutional trends in assessment for academic promotion.

The assessment of research performance is widely seen as a vital tool in upholding the highest standards of quality, with selection and competition believed to drive progress. Academic institutions need to take critical decisions on hiring and promotion, while facing external pressure by also being subject to research assessment. Here we present an outlook on research assessment for career progression with specific focus on promotion to full professorship, based on 314 policies from 190 academic institutions and 218 policies from 58 government agencies, covering 32 countries in the Global North and 89 countries in the Global South.
