A comprehensive analysis of albuminuria in canine chronic kidney disease.

Background: Albuminuria, an important marker of decreased kidney function in chronic kidney disease (CKD), is not routinely used for CKD detection or proteinuria appearance. Its relationships with biochemical parameters and blood pressure in dogs are poorly understood.

Objectives: This study aimed to evaluate the relationship of albuminuria with various CKD markers, its correlation with the urinary protein to creatinine ratio (UPC), and hypertension in dogs with early stages of CKD.

Comparative reassessment of AcrB efflux inhibitors reveals differential impact of specific pump mutations on the activity of potent compounds.

Multidrug resistance poses global challenges, particularly with regard to Gram-negative bacterial infections. In view of the lack of new antibiotics, drug enhancers, such as efflux pump inhibitors (EPIs), have increasingly come into focus. A number of chemically diverse agents have been reported to inhibit AcrB, the main multidrug transporter in , and homologs in other Gram-negative bacteria.

Serious About Getting Old?: Variability of Individual Old Age Risk Management in Czechia.

The global trend of transferring responsibility for dignified aging from the state to individuals is conducive to a variability of alternative attitudes and strategies. Despite having important implications for both the state and individuals, the variability of old age risk management has not been fully appreciated by social policy. Social policy cannot adapt to every individual, but it can reflect various categories of citizens and their patterns of old age risk management.

A Screening of Antimalarials Extends the Range of Known AcrB Efflux Substrates and Reveals Two Candidates with Antimicrobial Drug-Enhancing Activity.

Efflux by resistance nodulation cell division transporters, such as AcrAB-TolC in , substantially contributes to the development of Gram-negative multidrug resistance. Therefore, the finding of compounds that counteract efflux is an urgent goal in the fight against infectious diseases. Previously, an efflux inhibitory activity of the antimalarials mefloquine and artesunate was reported.

Dynamic changes in genomic and social structures in third millennium BCE central Europe.

Europe's prehistory oversaw dynamic and complex interactions of diverse societies, hitherto unexplored at detailed regional scales. Studying 271 human genomes dated ~4900 to 1600 BCE from the European heartland, Bohemia, we reveal unprecedented genetic changes and social processes. Major migrations preceded the arrival of "steppe" ancestry, and at ~2800 BCE, three genetically and culturally differentiated groups coexisted.
