The hypercortisolism is one of the hormonal features of anorexia nervosa (AN) in the undernutrition phase. This abnormality seems to be related to the nutritional factors because the weight restoration leads to the normalization of cortisol. We have investigated glycemia, plasma insulin and C-peptide like markers of carbohydrate metabolism, and, also, adrenocorticotrope hormone (ACTH), beta-endorphins and cortisol in basal and dynamics conditions in 142 patients with AN. Insulin negatively correlated with the values of cortisol at 16:00 h (r=-0.28, P<0.05, N=45); 04:00 h (r=-0.29, P<0.01, N=38). C-peptide negatively correlated with the values of cortisol at 08:00 h (r=-0.36, P<0.05, N=36); 12:00 h (r=-0.49, P<0.01, N=36); 16:00 h (r=-0.38, P<0.02, N=36); 20:00 h (r=-0.39, P<0.02, N=36); 04:00 h (r=-0.51, P<0.01, N=31); urinary free cortisol (r=-0.42, P<0.01, N=35); dexamethasone suppression test (DST; r=-0.52, P<0.01, N=30). C-peptide negatively correlated with the values of ACTH at 08:00 h (r=-0.33, P<0.05, N=37); 24:00 h (r=-0.38, P<0.05, N=32); 04:00 h (r=-0.49, P<0.01, N=31); DST (r=-0.45, P<0.02, N=25). We did not identify correlations between carbohydrate metabolism indices and beta-endorphins. These findings suggest that the nutritional factors may cause or maintain the hormonal changes of corticotrop axis in the undernutrition states.

Introduction: To further advance our understanding of Muscular Dystrophies (MDs) and Spinocerebellar Ataxias (SCAs), it is necessary to identify the biological patterns associated with disease pathology. Although progress has been made in the fields of genetics and transcriptomics, there is a need for proteomics and metabolomics studies. The present study aimed to be the first to document serum metabolic signatures of MDs (DMD, BMD, and LGMD 2A) SCAs (SCA 1-3), from a South Asian perspective.

Antarctic snow harbors diverse microorganisms, including pigmented algae and bacteria, which create colored snow patches and influence global climate and biogeochemical cycles. However, the genomic diversity and metabolic potential of colored snow remain poorly understood. We conducted a genome-resolved study of microbiomes in colored snow from 13 patches (7 green and 6 red) on the Fildes Peninsula, Antarctica.

Objectives: Mitochondrial Ca uniporter (MCU) provides a Ca influx pathway from the cytosol into the mitochondrial matrix and a moderate mitochondrial Ca rise stimulates ATP production and cell growth. MCU is highly expressed in various cancer cells including breast cancer cells, thereby increasing the capacity of mitochondrial Ca uptake, ATP production, and cancer cell proliferation. The objective of this study was to examine MCU inhibition as an anti-cancer mechanism.

The production of traditional agave spirits in Mexico, such as mezcal, involves a process that uses environmental microorganisms to ferment the cooked must from agave plants. By analysing these microorganisms, researchers can understand the dynamics of microbial communities at the interface of natural and human-associated environments. This study involved 16S and ITS amplicon sequencing of 99 fermentation tanks from 42 distilleries across Mexico.

Purpose: Glucose starvation induces the accumulation of disulfides and F-actin collapse in cells with high expression of SLC7A11, a phenomenon termed disulfidptosis. This study aimed to confirm the existence of disulfidptosis in pancreatic ductal adenocarcinoma (PDAC) and elucidate the role of Cancer Susceptibility 8 (CASC8) in this process.
Methods: The existence of disulfidptosis in PDAC was assessed using flow cytometry and F-actin staining.
