Regulators of G-protein signaling (RGS) are a family of approximately 30 proteins that bind to and deactivate the alpha subunits of G-proteins (G) by accelerating their GTP hydrolysis rates, which terminates G-protein coupled receptor (GPCR) signaling. Thus, RGS proteins are essential in regulating GPCR signaling, and most members are implicated as critical nodes in human diseases such as hypertension, depression, and others. Regulator of G-protein signaling 2 (RGS2), a member of the R4 family of RGS proteins, is overexpressed in many solid breast cancers, and its levels in prostate cancer significantly correlate with the metastatic stage and poor prognosis.

Polysomnography-guided full-night manual titration is the gold standard for continuous positive airway pressure titration, but it is cost-, time-, and effort-consuming. Alternative ways of titration are easier with less cost, time, and effort.

Background: We report the results of INICC surveillance study from 2013 to 2018, in 664 intensive care units (ICUs) in 133 cities, of 45 countries, from Latin-America, Europe, Africa, Eastern-Mediterranean, Southeast-Asia, and Western-Pacific.
Methods: Prospective data from patients hospitalized in ICUs were collected through INICC Surveillance Online System. CDC-NHSN definitions for device-associated healthcare-associated infection (DA-HAI) were applied.
Background: Short-term peripheral venous catheters-related bloodstream infections (PVCR-BSIs) rates have not been systematically studied, and data on their incidence by number of device-days is not available.
Methods: Prospective, surveillance study on PVCR-BSI conducted from September 1st, 2013 to 31st Mays, 2019 in 246 intensive care units (ICUs), members of the International Nosocomial Infection Control Consortium (INICC), from 83 hospitals in 52 cities of 14 countries in the Middle East (Bahrain, Egypt, Iran, Jordan, Kingdom of Saudi Arabia, Kuwait, Lebanon, Morocco, Pakistan, Palestine, Sudan, Tunisia, Turkey, and United Arab Emirates). We applied U.
The human dopamine transporter (hDAT) plays many vital functions within the central nervous system and is thus targeted by many pharmaceutical agents. Dopamine-related therapies are in current development for individuals with dopamine-related disorders including depression, Parkinson's disease, and psychostimulant addictions such as cocaine abuse. Yet, most efforts to develop new dopamine therapies are within costly structure-activity relationship studies.
