Mechanisms and functional significance of nuclear compartmentalization
… peripheral versus pericentric heterochromatin (PCH) targeting towards peripheral targeting. Targeting to both heterochromatin compartments is dependent on H3K9 trimethylation. More generally, PTRs confer targeting from the PCH to the periphery, from the interior to the PCH, or have no targeting …

Structure and Function Studies on tRNA Splicing Endonuclease
… Mendelian disease pontocerebellar hypoplasia (PCH) by an unknown mechanism. Recently, several groups have determined the structure of human TSEN, revealing similarities and differences between the human, yeast, and archaeal versions of the complex. This advance afforded us the opportunity to …

Influence of maternal human immunodeficiency virus (HIV) and antiretroviral (ARV) drugs on neonate neurometabolism.
… phosphocholine plus glycerophosphocholine (GPC+PCh) to Cr+PCr (GPC+PCh/Cr+PCr) in the basal ganglia (BG) of HEU neonates compared to HUU neonates, as seen previously for absolute concentrations of these metabolites in 9-year-old HEU children. Furthermore, we hypothesized lower Glu/Cr+PCr and …

Characterization of Membrane Organization and Dynamics in Giant Unilamellar Vesicles Assembled From Rat Kidney Membrane Extracts and Fragments
… of NaPi-IIa and using photon counting histogram (PCH) analysis to measure protein aggregation, we determined that the lateral diffusion of NaPi-IIa is slowed down and its aggregation is increased in potassium deficiency, both of which are associated with the decreased Na/Pi cotransport activity. …

The design and synthesis of polycyclic conjugated hydrocarbons via the incorporation of bifunctional Diels-Alder building blocks
… of polycyclic conjugated hydrocarbons (PCHs). In particular, we explore synthetic strategies to access polycyclic aromatic hydrocarbons and nonbenzenoid oligoacenes, and also discuss synthetic efforts to stabilize, solubilize and tune the properties of these classes of molecules. In …
