Summary: This study identified oxidative stress and protein oxidation as key factors in the onset of white striping myopathy, leading to severe loss of meat quality. The analysis showed that muscles affected by the myopathy exhibited chronic impairment of physiological and metabolic processes, indicating a disruption in protein turnover possibly mediated by oxidative stress.

Summary: The study aimed to investigate the effects of feedstuff containing oxidized protein and lipid on diet digestibility, growth performance, and oxidative stress in nursery pigs. Results showed that feeding pigs with oxidized proteins and lipids reduced feed intake and growth performance, but did not induce oxidative stress.

Summary: Cells respond to oxidative stress by inducing antioxidant proteins through the activation of Nrf2. Both Nrf2 and Keap1 are susceptible to protein misfolding under oxidative stress, potentially due to their intrinsic characteristics. This study provides new insights into the regulation of Nrf2 and Keap1 by oxidation-induced protein misfolding.

Summary: According to WHO statistics, millions of couples and individuals suffer from infertility, with varicocele identified as a leading cause of male infertility. This review examines the role of oxidative stress and reactive oxygen species (ROS) in the pathophysiology of varicocele and its impact on fertility. High levels of ROS can lead to infertility by damaging DNA, affecting lipid peroxidation, and inactivating enzymes and proteins involved in spermatogenesis.

Summary: Dementia is a syndrome that impairs learning and memory, and there is currently no effective therapy. Traditional Chinese medicine has shown potential in treating dementia, with the ability to improve memory and cognitive dysfunctions. It has fewer adverse effects and lower costs compared to prescription drugs.

Summary: English Summary: Graviola, a plant found in tropical regions, has various ethnomedicinal uses such as treating insomnia, diabetes, cystitis, and headaches. It contains active components called annonaceous acetogenins, with over 100 compounds isolated from it. Graviola is also a source of phenolic compounds, essential oils, alkaloids, flavonol triglycosides, and megastigmanes, as well as several minerals. This paper provides an overview of the antioxidant properties of graviola and its major constituents, based on a review of electronic databases, but more research is needed to determine its antioxidant potential and safety.

Summary: We investigated the association between cerebrospinal fluid (CSF) biomarkers indicating oxidative damage to proteins and the course of illness and outcome in childhood bacterial meningitis (BM) in Angola. We found that children with a lower o-Tyr/Phe ratio in their CSF upon admission were more likely to experience focal convulsions and secondary fever during recovery and have a suboptimal outcome at Day 7 and one month after discharge. The most common sequelae observed in these children were ataxia. This suggests that a higher admission CSF o-Tyr/Phe ratio is associated with a better course and outcome in pediatric BM.

Summary: Fibrinogen in blood plasma may have a role in antioxidant defense, as it reacts with the biological oxidant hypochlorite to form high molecular weight assemblies with potential antioxidant properties. Unlike hypochlorite-modified albumin, hypochlorite-modified fibrinogen does not induce reactive oxygen species production or cell death in immune cells. The interaction of hypochlorite with fibrinogen in plasma may reduce the accumulation of other hypochlorite-modified species, indicating a novel role for fibrinogen in blood plasma antioxidant defense.

Summary: Pn3G5G, derived from LRF, exhibited strong antioxidant capacity and protective effects on CML-treated cells. In aging mice, Pn3G5G improved cognitive impairment, neuroinflammation, and neuronal apoptosis. These findings suggest the potential development of Pn3G5G as a healthcare product or potent dietary supplement with antioxidant and neuroprotective effects.

Summary: This passage challenges the traditional view that amyloid is the leading cause of AD, proposing instead that the progressive decline in brain energy levels during aging is the main risk factor for dementia in older individuals. It suggests that optimizing brain energetics should be a key component in future strategies for preventing and treating dementia.

Summary: The study found significantly lower concentrations of tryptophan pathway metabolites in the AD group, while higher concentrations of indoleamine pathway metabolites were observed. Concentrations of various metabolites showed a decreasing trend with clinical diagnosis: control > MCI > AD. There were no significant differences between the two MCI subgroups, and the use of SSRI medication influenced serum observations but not urine results.

Summary: This review summarizes the current knowledge on targeting senescent cells to reduce the risk of age-related diseases, including the use of senotherapeutic strategies and drugs. Research suggests that senotherapeutic approach may be translatable to humans, but caution is needed due to a lack of evidence of potential side-effects of senolytic agents.

Summary: Psychotic symptoms in Alzheimer's disease are common and have genetic components, with significant associations found in two loci - ENPP6 and SUMF1. AD + P shows negative genetic correlations with cognitive and educational attainment, and positive genetic correlations with depressive symptoms. This study provides insights into the genetic architecture of psychosis in Alzheimer's disease.

Summary: Alzheimer's disease (AD) is the leading cause of dementia globally and is a major contributor to disability in older individuals. Vitamin E levels are lower in AD patients, and inflammation and microRNAs also play significant roles in the development of AD. MiR-122 may be a modulating factor, correlating with alpha-tocopherol and inflammation molecules.

Summary: The concept of intermediate care is increasingly recognized in Italy as a critical strategy to improve healthcare quality and integration across different settings. Person-tailored care is a key challenge, requiring a shift towards a holistic approach that prioritizes individual preferences and values. This necessitates greater collaboration, communication, and innovation in care delivery, including the use of technology for remote monitoring. Despite challenges, intermediate care offers significant opportunities to enhance care quality, reduce costs, and promote social cohesion and community engagement.
