Biochemical and cellular studies of three human 3-phosphoglycerate dehydrogenase variants responsible for pathological reduced L-serine levels.

In the brain, the non-essential amino acid L-serine is produced through the phosphorylated pathway (PP) starting from the glycolytic intermediate 3-phosphoglycerate: among the different roles played by this amino acid, it can be converted into D-serine and glycine, the two main co-agonists of NMDA receptors. In humans, the enzymes of the PP, namely phosphoglycerate dehydrogenase (hPHGDH, which catalyzes the first and rate-limiting step of this pathway), 3-phosphoserine aminotransferase, and 3-phosphoserine phosphatase are likely organized in the cytosol as a metabolic assembly (a "serinosome"). The hPHGDH deficiency is a pathological condition biochemically characterized by reduced levels of L-serine in plasma and cerebrospinal fluid and clinically identified by severe neurological impairment.

Effects of supplementing Saccharomyces cerevisiae fermentation products to dairy cows from the day of dry-off through early lactation.

The scope of this experiment was to study the effects of Saccharomyces cerevisiae fermentation product (SCFP; NutriTek, Diamond V) on milk yield, milk composition, somatic cell count, rumination activity, and immunometabolic profile (inflammation) of dairy cows during the peripartum period. Postpartum inflammation severity was evaluated as the liver functionality index (LFI). The LFI is based on profiles of specific blood inflammatory markers in the first month of lactation.

Silibinin-hydroxypropyl-β-cyclodextrin (SLB-HP-β-CD) complex prevents apoptosis in liver and kidney after hepatic ischemia-reperfusion injury.

Background: We investigated the protective effect of silibinin on rat liver and kidney after hepatic inschemia/reperfusion (I/R) injury.

Methods And Materials: Sixty three male Wistar-type rats (median age 13 weeks; average weight 314 g) were subjected to I/R injury of the liver. They were randomly divided into three groups: Sham (n = 7), Control (C, n = 28) and Silibinin (Si, n = 28).

Tuberculosis and comorbidities in urban areas in Argentina. A gender and age perspective.

Introduction: Tuberculosis continues to be a major health problem in the world with an incidence of more than 10 million cases in 2015. There are factors that change the risk of developing the disease after infection, as well as the presentation of the disease.

Objective: To determine the main comorbidities and demographic, clinical and microbiological characteristics of tuberculosis adult patients in Argentina from a gender and age perspective.

Risk factors associated with tuberculosis mortality in adults in six provinces of Argentina.

Tuberculosis (TB) remains a cause of illness and death across the world, especially in developing countries and vulnerable population groups. In 2013, 1.5 million died from the disease worldwide.
