Survival among older adults with kidney failure is better in the first three years with chronic dialysis treatment than not.

Comparisons of survival between dialysis and nondialysis care for older adults with kidney failure have been limited to those managed by nephrologists, and are vulnerable to lead and immortal time biases. So we compared time to all-cause mortality among older adults with kidney failure treated vs. not treated with chronic dialysis.

Discovery of (1S,2R,3S,4S,5R,6R)-2-Amino-3-[(3,4-difluorophenyl)sulfanylmethyl]-4-hydroxy-bicyclo[3.1.0]hexane-2,6-dicarboxylic Acid Hydrochloride (LY3020371·HCl): A Potent, Metabotropic Glutamate 2/3 Receptor Antagonist with Antidepressant-Like Activity.

As part of our ongoing efforts to identify novel ligands for the metabotropic glutamate 2 and 3 (mGlu) receptors, we have incorporated substitution at the C3 and C4 positions of the (1S,2R,5R,6R)-2-amino-bicyclo[3.1.0]hexane-2,6-dicarboxylic acid scaffold to generate mGlu antagonists.

Novel bicyclo[3.1.0]hexane analogs as antagonists of metabotropic glutamate 2/3 receptors for the treatment of depression.

Negative modulators of metabotropic glutamate 2 & 3 receptors demonstrate antidepressant-like activity in animal models and hold promise as novel therapeutic agents for the treatment of major depressive disorder. Herein we describe our efforts to prepare and optimize a series of conformationally constrained 3,4-disubstituted bicyclo[3.1.

Opt-outs and upgrades. Ethics and law in the United Kingdom.

We report on two areas in which UK law and ethics seem out of step with each other. 2013 saw the passing of the Human Transplantation (Wales) Bill, which will introduce an opt-out system of organ donation in Wales from 2015. In the first section, we discuss the convoluted evolution of the Bill and some potential problems that we consider may prevent it from achieving its intended goal of increasing the number of organs transplanted.

Structure-activity relationship studies of carboxamido-biaryl ethers as opioid receptor antagonists (OpRAs). Part 1.

A structurally unique and new class of opioid receptor antagonists (OpRAs) that bear no structural resemblance with morphine or endogenous opioid peptides has been discovered. A series of carboxamido-biaryl ethers were identified as potent receptor antagonists against mu, kappa and delta opioid receptors. The structure-activity relationship indicated para-substituted aryloxyaryl primary carboxamide bearing an amine tether on the distal phenyl ring was optimal for potent in vitro functional antagonism against three opioid receptor subtypes.

Leveraging the power of the media to combat HIV/AIDS.

Improving HIV/AIDS prevention efforts, especially those focused on young people, is a key challenge in the fight against the pandemic. Since the mid-1990s the Henry J. Kaiser Family Foundation has partnered with U.
