Background/Objectives: Aging and chronic stress are regarded as the most important risk factors of cognitive decline. Aged spontaneously hypertensive rats (SHRs) represent a suitable model age-related vascular brain diseases. The aim this study was to explore effects isolation in aging SHRs on their functions response acute stress, well influence oral intake N-Pep-Zn, Zn derivative N-PEP-12. Methods: Nine-month-old were subjected social for 3 months (SHRiso group), one group received N-pep-Zn orally (SHRisoP, 1.5 mg/100 g BW). housed groups served control (SHRsoc). behavioral included following tests: sucrose preference, open field, elevated plus maze, three-chamber sociability novelty spatial learning memory Barnes maze. Levels corticosterone, glucose proinflammatory cytokines blood plasma salivary amylase activity measured. Restraint (60 min) used test response. Results: Isolation negatively affected while treatment isolated with N-Pep-Zn improved long-term working impairments, making SHRisoP comparable SHRsoc group. Acute induced decrease relative thymus weight SHRiso (but not SHRsoc), whereas prevented involution. mitigated increment cortisol levels by stress. Conclusions: enhanced adaptive capabilities towards (isolation) (immobilization) aged disturbances isolation, probably affecting hypothalamo–pituitary–adrenal, sympathetic, immune systems.

The human microbiome plays a vital role in health, mediated by the gut–brain axis, with large diversity of functions and physiological benefits. dynamics mechanisms meditations on oral gut modulations are not well understood. This study investigates short-term during an Arhatic Yoga meditation retreat as improving well-being through possible gut-brain axis. A single-arm pilot clinical trial was conducted controlled environment 9-day intensive practices vegetarian diet. Oral fecal samples 24 practitioners were collected at start (Day0: T1), middle (Day3: T2), end (Day9:T3) retreat. Targeted 16S rRNA gene amplicon sequencing performed for both samples. Functional pathway predictions identified using phylogenetic investigation communities reconstruction unobserved states (PICRUSt2). DESeq2 used to identify differential abundant taxa.

The microbiota-gut-brain axis is a complex bidirectional communication system that involves multiple interactions between intestinal functions and the emotional cognitive centers of brain. These are mediated by molecules (metabolites) produced in both areas, which considered mediators. To shed light on this mechanism, still largely unknown, reliable characterization mediators essential. Here, we review most studied metabolites axis, metabolic pathways they involved, their functions. This focuses mainly use mass spectrometry for determination, reporting latest analytical methods, limitations, future perspectives. strategy qualitative-quantitative must be order to elucidate molecular mechanisms underlying influence above-mentioned stress resilience or vulnerability.

BACKGROUND Functional gastrointestinal disorders (FGIDs) in children present with chronic symptoms like abdominal pain, diarrhea, and constipation without identifiable structural abnormalities. These are closely linked to gut-brain axis dysfunction, altered gut microbiota, psychosocial stress, leading psychiatric comorbidities such as anxiety, depression, behavioral issues. Understanding this bidirectional relationship is crucial for developing effective, holistic management strategies that address physical mental health. AIM To examine the impacts of FGIDs children, focusing on anxiety depression their association other neurodevelopmental childhood, attention-deficit/hyperactivity disorder, emphasizing role axis, emotional dysregulation, stress. Key mechanisms explored include neurotransmitter microbiota imbalance, central sensitization, heightening stress reactivity, symptom perception. The review also evaluates family dynamics coping exacerbating FGID contributing conditions. METHODS A narrative was conducted using 328 studies sourced from PubMed, Scopus, Google Scholar, covering research published over past 20 years. Inclusion criteria focused examining diagnosis, mechanisms, comorbidities, factors pediatric populations. commonly affecting including functional constipation, irritable bowel syndrome, gastroesophageal reflux, cyclic vomiting were analyzed concerning psychological impacts. RESULTS highlights a strong connection between symptoms, mediated by dysregulated sensitization. physiological disruptions increase children’s vulnerability while - early-life trauma, maladaptive dynamics, ineffective intensify cycle distress. CONCLUSION Effective requires biopsychosocial approach integrating medical, psychological, dietary interventions. Parental education, early intervention, multidisciplinary care coordination critical mitigating long-term improving both health outcomes FGIDs.

This narrative review aims explore the relationship between immune system, focusing on how environmental stressors can affect regulation, both hyperactivity suppression. Methods A comprehensive search was conducted in PubMed Google Scholar for peer‐reviewed studies published up June 2024. The terms included “climate change,” “human health,” “infection,” “immunity,” “disease.” Inclusion criteria were based relevance, originality, accessibility. Results Exposure elevated temperatures significantly impair system cells, an overproduction of signaling molecules that promote inflammation. Temperature fluctuations been shown influence various aspects adaptive response, including cell mobilization, antigen processing presentation, lymphocyte trafficking activation, functionality B T cells. Notably, some research suggests heat stress negatively impacts differentiation, replication, proportion, resulting decreased immunoglobulin cytokine production, contributing immunosuppression. Additionally, change‐related exposures compromise epithelial barriers skin, lungs, gut, microbial dysbiosis, dysregulation. Furthermore, factors such as temperature variations, humidity, air pollutant levels may exacerbate prevalence infectious diseases, measles HIV, with varying acute, chronic, latent infections, further variability. Conclusion Climate change, particularly increased function, heightened inflammatory responses, Future should focus developing sustainable management strategies enhance health resilience face ongoing climatic changes.
