Sweet, bloody consumption - what we eat and how it affects vascular ageing, the BBB and kidney health in CKD.

In today's industrialized society food consumption has changed immensely toward heightened red meat intake and use of artificial sweeteners instead of grains and vegetables or sugar, respectively. These dietary changes affect public health in general through an increased incidence of metabolic diseases like diabetes and obesity, with a further elevated risk for cardiorenal complications. Research shows that high red meat intake and artificial sweeteners ingestion can alter the microbial composition and further intestinal wall barrier permeability allowing increased transmission of uremic toxins like p-cresyl sulfate, indoxyl sulfate, trimethylamine n-oxide and phenylacetylglutamine into the blood stream causing an array of pathophysiological effects especially as a strain on the kidneys, since they are responsible for clearing out the toxins.

Monitoring the redox-driven assembly/disassembly of a dicopper(I) helicate with an auxiliary fluorescent probe.

The assembly/disassembly of a dicopper(I) helicate with a bis-bidentate imine-quinoline ligand is driven by the Cu(II)/Cu(I) redox change and is signaled by a fluorescent probe bearing a -COO(-) group (coumarine 343). The probe coordinates the Cu(II) center of the monomeric complex, which quenches its emission (fluorescence off), and is released upon reduction and formation of the Cu(I) helicate (fluorescence on).

Activity of daptomycin against enterococci and coagulase-negative staphylococci (CNS): relationship between CNS susceptibility and slime production.

We compared the in vitro activity of daptomycin, a new lipopeptide antibiotic, with that of vancomycin and other selected agents against 95 coagulase negative staphylococci (CNS) isolates causing septicemia or foreign-body infections in immunocompromised patients. These strains were classified as follows: 51 methicillin-susceptible CNS (23 slime producers); 44 methicillin-resistant CNS (23 slime producers). We also investigated the activity of daptomycin against 50 Enterococcus faecalis isolates.

Pharmacokinetics of nicorandil in patients with normal and impaired renal function.

The pharmacokinetics of oral nicorandil 20 mg 12 hourly for 9 doses was evaluated in 21 hospitalized patients with angina pectoris due to coronary heart disease and with normal and impaired renal function. Patients were divided into 3 groups based on creatinine clearance (CLCr): GROUP I (n = 6) greater than 80 ml/min, GROUP II (n = 8) 20-80 ml/min, and GROUP III (n = 7) less than 20 ml/min. After the first dose, the total clearance of nicorandil (CL) value did not change with increasing renal failure and so was not dependent on creatine clearance.
