AI Article Synopsis

  • The study explores the link between selenium deficiency (SeD) and oxidative stress by looking at growth and liver damage in SeD rats of different ages.
  • The SeD rats showed greater liver-to-body weight ratios and higher liver damage markers (AST and ALT), particularly in younger rats (6-12 weeks).
  • Results indicated that oxidative damage (measured by TBARS levels) changed with age, with young SeD rats exhibiting higher levels compared to normal rats, while older normal rats had increased TBARS levels.

Article Abstract

Previous studies have implied a relationship between Se-deficiency and oxidative stress. In the present study, the occurrence of oxidative stress due to Se-deficiency was investigated by evaluating the age dependence of growth and indices of oxidative damage for the liver of Se-deficient (SeD) rats. The ratios of liver weight to body weight of the SeD rats were greater than those of the normal rats. The values of AST and ALT (clinical indices of liver damage) were higher in the SeD rats than the normal ones especially in the young (6-12 weeks of age). The TBARS level of the 4-week-old SeD group were higher than the normal group while the level decreased with age. Conversely, the TBARS level of the normal group gradually increased and became higher than SeD group in older rats (12-20 weeks of age). Vitamin E rather than vitamin C may be consumed during oxidative stress due to Se-deficiency. Damage induced by Se-deficiency may be related to growth and the mechanisms of this damage may alter with age.

Background: Vanadium (VAN) is a significant trace element, but its higher exposure is reported to cause severe organ toxicity. Tectochrysin (TEC) is a naturally derived flavonoid which demonstrates a wide range of pharmacological properties.

Aim: The current study was planned to assess the cardioprotective potential of TEC against VAN induced cardiotoxicity in rats via regulating biochemical, and histological profile.

Perfluorooctane sulfonate (PFOS) and its new substitute, perfluorobutane sulfonate (PFBS), are increasing in concentration in the environment annually, and their toxicity cannot be ignored. With an increasing amount of PFOS and PFBS entering the environment, especially into farmland soil, it is very likely to pollute tobacco-planting soil. Therefore, we chose tobacco (Nicotiana tabacum L.

Sound and Alzheimer's Disease-From Harmful Noise to Beneficial Soundscape Augmentation and Music Therapy.

Noise Health

January 2025

Institute of Hygiene and Medical Ecology, Faculty of Medicine, University of Belgrade, Belgrade, Serbia.

Exposure to sound energy may be a risk factor or a therapeutic intervention for Alzheimer's disease (AD). On one hand, noise has a harmful effect on people with AD by contributing to hearing loss, sleep disturbance, oxidative stress, inflammation, and excitotoxicity. But on the other hand, clinical trials and nursing home interventions with soundscape augmentation involving natural sounds have shown promising results in alleviating psychophysiological symptoms in people with AD.

Filamentous plant pathogenic fungi pose significant threats to global food security, particularly through diseases like Fusarium Head Blight (FHB) and Septoria Tritici Blotch (STB) which affects cereals. With mounting challenges in fungal control and increasing restrictions on fungicide use due to environmental concerns, there is an urgent need for innovative control strategies. Here, we present a comprehensive analysis of the stage-specific infection process of Fusarium graminearum in wheat spikes by generating a dual weighted gene co-expression network (WGCN).

The metabolic landscape of cancer greatly influences antitumor immunity, yet it remains unclear how organ-specific metabolites in the tumor microenvironment influence immunosurveillance. We found that accumulation of primary conjugated and secondary bile acids (BAs) are metabolic features of human hepatocellular carcinoma and experimental liver cancer models. Inhibiting conjugated BA synthesis in hepatocytes through deletion of the BA-conjugating enzyme bile acid-CoA:amino acid -acyltransferase (BAAT) enhanced tumor-specific T cell responses, reduced tumor growth, and sensitized tumors to anti-programmed cell death protein 1 (anti-PD-1) immunotherapy.
