Paul Lee PTH - Vitamin D - Glycemia Interactions Reloaded

Traditionally viewed as a key regulator of musculoskeletal health, recent studies also have pointed to pleiotropic roles of vitamin D in the modulation of metabolic and vascular functions (1). Hypovitaminosis D is associated with obesity (2), and low vitamin D states predict higher fasting glycemia and insulin resistance in population studies (3,4), yet other studies showed no relations between...

Lecture 17: D-Stable Polynomials and Lee-Yang Theorems

Counting vs Sampling We called this course counting and sampling because of the equivalence theorem that we proved at the beginning of this course. All results that we proved using MCMC technique naturally give (approximate) sampler from our desired probability distributions. On the other hand, all results in the second part of the course naturally estimate the corresponding partition function ...

Profile of Charles D. Gilbert.

Neuroscientists once thought that the brain’s wiring was fixed in early life, but the pioneering research of National Academy of Sciences member Charles Gilbert continues to show that the adult brain is remarkably dynamic. Evidence supporting that view is presented in Gilbert and colleagues’ studies of the neural mechanisms underlying visual perception, learning, and memory. Gilbert, the Arthur...

Profile of Alexander D. Johnson.

Discussing the yeast Candida albicans, biochemist Alexander Johnson describes a resident of the human gut that can turn into a fatal pathogen in the immunocompromised. Johnson, a professor of microbiology and immunology at the University of California, San Francisco, appreciates the genetic intricacies of this eukaryote that changed his views on transcriptional regulation and the evolution of m...
