[Structural and functional features of the main arteries of the brain and tumor necrosis factor-alpha in people with chronic non-infectious diseases].

Objective: To investigate the structural and functional characteristics of the carotid and vertebral arteries and their relationship with tumor necrosis factor-alpha (TNF-α) levels in patients with chronic non-infectious diseases (CNIDs), considering sex differences.

Unlabelled: Material and Methods. A retrospective analysis of clinical and laboratory data of 760 patients with chronic non-communicable diseases (average age 52.

Venous Excess Ultrasound Score Is Associated with Worsening Renal Function and Reduced Natriuretic Response in Patients with Acute Heart Failure.

The venous excess ultrasound score (VExUS) is used to objectify systemic venous congestion. The aim of the paper was to determine the association between VExUS grades and worsening renal function (WRF), reduced natriuretic response, diuretics resistance, and mortality in patients with acute heart failure (AHF). One hundred patients were included, and Doppler ultrasound of hepatic, portal, and renal veins was performed.

The Assessment of Methyl Methanesulfonate Absorption by Amphipods from the Environment Using Lux-Biosensors.

The ability of aquatic mesofauna representatives involved in trophic chains to sorb and accumulate toxicants is important for understanding the functioning of aquatic ecosystems and for fishing industry. This study investigated the capacity of marine amphipod and freshwater amphipods and to absorb the DNA-alkylating agent methyl methanesulfonate (MMS). The presence of alkylating agents in the environment and in the tissues of the amphipods was determined using whole-cell lux-biosensor MG1655 pAlkA-lux, in which the genes from , enabling the luminescence of the cell culture, are controlled by the P promoter of DNA glycosylase.

luxA Gene From Enhygromyxa salina Encodes a Functional Homodimeric Luciferase.

Several clades of luminescent bacteria are known currently. They all contain similar lux operons, which include the genes luxA and luxB encoding a heterodimeric luciferase. The aldehyde oxygenation reaction is presumed to be catalyzed primarily by the subunit LuxA, whereas LuxB is required for efficiency and stability of the complex.
