Association Between Sleep Duration and Cardiovascular Disease Among Asian Americans.

Background: Cardiovascular disease (CVD) prevalence varies widely among Asian American adults. The American Heart Association added healthy sleep to its metrics to define ideal cardiovascular health. Little is known about the association between sleep and CVD prevalence among Asian subgroups.

Woolly Monkey-HBV Infection in Squirrel Monkeys as a Surrogate Nonhuman Primate Model of HBV Infection.

Development of curative therapies for chronic hepatitis B virus (HBV) infection will likely require new animal models. Here, we evaluate HBV infection in squirrel monkeys based on the high-sequence homology of the HBV receptor, Na+/taurocholate co-transporting peptide (NTCP), between humans and squirrel monkeys. HBV PreS1 peptide was examined for binding human and squirrel monkey NTCP.

Dysregulation of protein phosphatase 2A in parkinson disease and dementia with lewy bodies.

Objective: Protein phosphatase 2A (PP2A) is a heterotrimeric holoenzyme composed of a catalytic C subunit, a structural A subunit, and one of several regulatory B subunits that confer substrate specificity. The assembly and activity of PP2A are regulated by reversible methylation of the C subunit. -Synuclein, which aggregates in Parkinson disease (PD) and dementia with Lewy bodies (DLB), is phosphorylated at Ser, and PP2A containing a B55 subunit is a major phospho-Ser phosphatase.

Cadherins and their connections: adhesion junctions have broader functions.

Cadherins - a family of cell-cell adhesion molecules - are linked to the actin cytoskeleton via intervening proteins. Recent results address molecular explanations for observed cadherin behavior, point to signals that regulate adhesion by modulating elements of the cadherin-associated complex, challenge the belief that different cadherins generally cannot cross-adhere, and highlight instructive roles for cadherins in cell signaling and differentiation.

Fibronectin fibrillogenesis: a paradigm for extracellular matrix assembly.

Fibronectin matrix assembly is a regulated stepwise process. In the past year, analyses of fibronectin domains, integrin and cytoskeletal contributions, and fibril architecture have provided new insights into assembly mechanisms and matrix control of cell functions. Like fibronectin, laminin polymerization is cell-mediated.
