During meiosis, each pair of homologous chromosomes becomes connected by at least one crossover, as required for accurate segregation, and adjacent crossovers are widely separated thereby limiting total numbers. In coarsening models, this crossover patterning results from nascent recombination sites competing to accrue a limiting pro-crossover RING-domain protein (COR) that diffuses between synapsed chromosomes. Here, we delineate the localization dynamics of three mammalian CORs in the mouse and determine their interdependencies.

The prevalence of hypertension (HTN) and diabetes mellitus (DM) is increasing worldwide, and their coexistence is well-documented. Managing both conditions is challenging due to shared pathophysiological mechanisms and the need to balance blood pressure (BP) control with glycemic management. The objective of this protocol was to consider the prescribing pattern and effectiveness of antihypertensive agents in hypertensive and diabetic patients, with and without compelling indications, at tertiary care hospital.

While the role of biochemical stimuli in the modulation of macrophage function is well studied, the role of biophysical cues and the molecules involved in mechanosensation are less well understood. Here, we use genetic and pharmacological tools to show extracellular oxidized low-density lipoproteins (oxLDLs) stimulate Ca signaling through activation of the mechanically gated ion channel Piezo1.
