Plasma Proteomic Signatures of Physical Activity Provide Insights into Biological Impacts of Physical Activity and its Protective Role Against Dementia.

Physical activity (PA), including sedentary behavior, is associated with many diseases, including Alzheimer's disease and all-cause dementia. However, the specific biological mechanisms through which PA protects against disease are not entirely understood. To address this knowledge gap, we first assessed the conventional observational associations of three self-reported and three device-based PA measures with circulating levels of 2,911 plasma proteins measured in the UK Biobank (n =39,160) and assessed functional enrichment of identified proteins.

Associations Between Walking Pace, APOE-ε4 Genotype, and Brain Health in Middle-Aged to Older Adults.

Poor physical function and possession of the e4 allele of the apolipoprotein E (APOE) gene are each associated with increased dementia risk, but it is unclear how these exposures interact to influence brain health. Purpose: To investigate whether self-reported walking pace (a marker of physical function) and the presence of APOE-ε4 allele interact to modify brain health outcomes. Methods: We used data from a prospective cohort study of middle-aged to older adults from the UK Biobank who self-reported walking pace (slow or steady-to-brisk), and who were initially free of dementia (n = 415,110).

Identification, Biocontrol and Plant Growth Promotion Potential of Endophytic Streptomyces sp. a13.

Medicinal plants often harbour various endophytic actinomycetia, which are well known for their potent antimicrobial properties and plant growth-promoting traits. In this study, we isolated an endophytic actinomycetia, A13, from the leaves of tea clone P312 from the MEG Tea Estate, Meghalaya, India. The isolate A13 was identified as Streptomyces sp.

Impact of Antenatal Corticosteroids on Cortisol and Glucose Homeostasis Levels in Preterm Neonates: A Meta-Analysis.

Antenatal corticosteroids (ACS) are widely used to reduce respiratory distress syndrome (RDS) in preterm neonates, enhancing neonatal outcomes. However, the potential effects of ACS on other aspects of neonatal health, such as cortisol levels and glucose regulation, remain a concern. This study examines whether ACS administration impacts cortisol and glucose homeostasis in preterm infants by analyzing data from 14 selected studies.

Caval valve implantation: First of its kind in a rare environment.

Transcatheter caval valve implantation (CAVI) is an emerging treatment option for inoperable patients with severe tricuspid regurgitation (TR). We present a case of a 76-year-old lady with severe TR and recurrent right heart failure who improved after CAVI. This is the first such case in a rare environment.
