Clinical trial evidence to support combination therapy with angiotensin-converting enzyme inhibitors and
angiotensin II receptor blockers in chronic kidney disease has largely been based on proteinuria reduction as a surrogate marker for clinically meaningful outcomes. Recent large-scale randomized clinical trials have not been able to validate protection in halting progression in chronic kidney disease with a dual blockade approach. This review serves as an appraisal on the clinical evidence of combination angiotensin-converting enzyme inhibition and angiotensin II receptor blockade in both cardiovascular disease and chronic CFTRinh-172 kidney disease.”
“Nicotinamide phosphoribosyltransferase (Nampt) converts nicotinamide to nicotinamide mononucleotide (NMN), a key nicotinamide adenine dinucleotide (NAD) intermediate. Previously identified as a cytokine pre-B-cell colony-enhancing factor and controversially claimed as an insulin-mimetic hormone
visfatin, Nampt has recently drawn much attention in several fields, including NAD biology, metabolism and inflammation. As a NAD biosynthetic enzyme, Nampt regulates the activity of NAD-consuming Selleck NVP-BSK805 enzymes such as sirtuins and influences a variety of metabolic and stress responses. Nampt also plays an important part in regulating insulin secretion in pancreatic beta-cells. Nampt seems to have another function as an immunomodulatory
cytokine and, therefore, has a role in inflammation. This review summarizes these various functional aspects of Nampt and discusses its potential roles in diseases, including type 2 diabetes and cancer.”
“Introduction Cannabis users have been reported to have decreased regional cerebral glucose metabolism after short periods of abstinence. The purpose of this study was to measure striatal dopamine receptor (D-2/D-3) availability and cerebral glucose metabolism with positron emission tomography (PET) in young adults who had a prolonged exposure to cannabis and who had been abstinent for a period of at least 12 weeks.
Materials and methods Six 18-21-year-old male subjects with cannabis PTK6 dependence in early full remission and six age- and sex-matched healthy subjects underwent PET scans for D-2/D-3 receptor availability measured with [C11]-raclopride and glucose metabolism measured with [18F]-FDG. All subjects were sober for at least 12 weeks before PET scan procedures. PET data were analyzed with statistical parametric mapping software (SPM99; uncorrected p < 0.001, corrected p < 0.05 at the cluster level). Toxicology screening was performed prior to the PET scan to confirm the lack of drugs of abuse.
Observations and results Striatal D-2/D-3 receptor availability did not differ significantly between groups.
