41 liquidators of 40-70 years old who had worked in the Chernobyl accident area and 30 patients of the same age (control group) were examined. The lipid spectrum of blood and cerebral haemodynamics (Duplex ultrasound scanning of magisterial arteries of the head) were examined. The results indicate that influence of low radiation stimulates the aterogenic forms of dislipoproteinemia and accelerated atherogenesis. The conclusion is made about marked structural and functional changes in cerebral vascular system taking place under the influence of low radiation in patients of older age groups.

Telomere Length and Oxidative Damage in Children and Adolescents with Autism Spectrum Disorder: A Systematic Review and Meta-Analysis.
J Integr Neurosci

Department of Child Health, Qingdao Huangdao District Central Hospital, 266555 Qingdao, Shandong, China.
Background: Autism spectrum disorder (ASD) has been reported to confer an increased risk of natural premature death. Telomere erosion caused by oxidative stress is a common consequence in age-related diseases. However, whether telomere length (TL) and oxidative indicators are significantly changed in ASD patients compared with controls remains controversial.

Background/objectives: Autism spectrum disorder (ASD) is characterized by impaired social interaction and repetitive stereotyped behavior. Effective interventions for the core autistic symptoms are currently limited.
Methods: This study employed a valproic acid (VPA)-induced mouse model of ASD to assess the preventative effects of L-proline supplementation on ASD-like behaviors.

Bacteriophage therapy represents a promising strategy to combat multidrug-resistant pathogens, such as . In this study, we explored the effects of a bacteriophage infection on an Extended Spectrum Beta-Lactamase (ESBL) positive isolate. We used next generation sequencing, proteomics and phenotypic screens to investigate the effect of bacteriophage infections on metabolism and resistance phenotypes.

The COVID-19 pandemic, caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), is in its sixth year and is being maintained by the inability of current spike-alone-based COVID-19 vaccines to prevent transmission leading to the continuous emergence of variants and sub-variants of concern (VOCs). This underscores the critical need for next-generation broad-spectrum pan-Coronavirus vaccines (pan-CoV vaccine) to break this cycle and end the pandemic. The development of a pan-CoV vaccine offering protection against a wide array of VOCs requires two key elements: (1) identifying protective antigens that are highly conserved between passed, current, and future VOCs; and (2) developing a safe and efficient antigen delivery system for induction of broad-based and long-lasting B- and T-cell immunity.

Background: Huntington's disease (HD) is a multifaceted neurological disorder characterized by the progressive deterioration of motor, cognitive, and psychiatric functions. Despite a limited understanding of its pathogenesis, research has implicated abnormal trinucleotide cytosine-adenine-guanine CAG repeat expansion in the huntingtin gene (HTT) as a critical factor. The development of innovative strategies is imperative for the early detection of predictive biomarkers, enabling timely intervention and mitigating irreversible cellular damage.
