Differing sensitivities to angiotensin converting enzyme inhibition of kidney disease mediated by APOL1 high-risk variants G1 and G2.

Apolipoprotein L1 (APOL1) variants G1 and G2 contribute to the excess risk of kidney disease in individuals of recent African ancestry. Since disease mechanisms and optimal treatments remain controversial, we study the effect of current standard-of-care drugs in mouse models of APOL1 kidney disease. Experiments were performed in APOL1 BAC-transgenic mice, which develop proteinuria and glomerulosclerosis following injection with a pCpG-free IFN-γ plasmid.

UNITY: A low-field magnetic resonance neuroimaging initiative to characterize neurodevelopment in low and middle-income settings.

Measures of physical growth, such as weight and height have long been the predominant outcomes for monitoring child health and evaluating interventional outcomes in public health studies, including those that may impact neurodevelopment. While physical growth generally reflects overall health and nutritional status, it lacks sensitivity and specificity to brain growth and developing cognitive skills and abilities. Psychometric tools, e.

The CALIPR framework for highly accelerated myelin water imaging with improved precision and sensitivity.

Quantitative magnetic resonance imaging (MRI) techniques are powerful tools for the study of human tissue, but, in practice, their utility has been limited by lengthy acquisition times. Here, we introduce the Constrained, Adaptive, Low-dimensional, Intrinsically Precise Reconstruction (CALIPR) framework in the context of myelin water imaging (MWI); a quantitative MRI technique generally regarded as the most rigorous approach for noninvasive, in vivo measurement of myelin content. The CALIPR framework exploits data redundancy to recover high-quality images from a small fraction of an imaging dataset, which allowed MWI to be acquired with a previously unattainable sequence (fully sampled acquisition 2 hours:57 min:20 s) in 7 min:26 s (4.

Production of Psychoactive Metabolites by Gut Bacteria.

The gut microbiome plays a vital role in numerous aspects of physiology, including functions related to metabolism, the immune system, behaviour, brain structure and function. Furthermore, it is now becoming increasingly clear that alterations in microbial composition or diversity are implicated in several disease states, including anxiety, depression, autism spectrum disorder (ASD), Alzheimer's disease (AD), Parkinson's disease (PD), obesity, and diabetes. Therefore, therapeutic targeting of the gut microbiota has the potential to be useful in the treatment of both stress-related disorders and metabolic diseases.
