Export-oriented markets increasingly require verifiable movement histories from smallholder aggregators. A permissioned ledger pilot linked ear-tag events, transport waybills, and abattoir inspection outcomes across three cooperative clusters. Participating buyers reported faster dispute resolution on lot mixing, while farmers valued tamper-evident vaccination logs; infrastructure gaps in rural connectivity remain the primary barrier to daily data entry.

Re-exposure of silage face to oxygen accelerates heating and mycotoxin risk in warm climates. Laboratory incubations of samples taken at zero, twelve, and twenty-four hours after partial-bag opening quantified temperature rise and yeast counts. Lactic acid bacteria inoculation at ensiling extended stable exposure time, but face management practices such as daily removal depth and sheeting proved equally influential in on-farm trials.

Economic shocks interact with biological constraints when farmers decide which cows to retain. A discrete-choice experiment embedded in a survey of Norwegian and Lithuanian dairy producers elicited stated culling rules under hypothetical price scenarios. Loss-averse respondents delayed culling of high-yielding cows with chronic mastitis history, whereas profit-maximizing profiles aligned more closely with recommended parity-based replacement models.

Frequent weight gain monitoring supports feed allocation and market timing but manual weighing stresses animals. A prototype platform integrating four load cells beneath a short race was validated against chute weights for steers over a ninety-day finishing period. Random-effects models show daily medians track individual growth curves with root mean square error under four kilograms when footing is kept dry and passage speed is controlled.

Blanket intramammary dry-cow treatment is increasingly questioned under antimicrobial stewardship policies. Quarterly bulk-tank culture results and individual cow somatic cell count histories from forty-six herds were used to model predicted cure and new-infection risk. Selective protocols reduced antibiotic use by roughly one third without increasing clinical mastitis incidence during the subsequent lactation when farmer training emphasized culture interpretation.

Declining rumination minutes often precede visible signs of heat stress when temperature-humidity index exceeds comfort thresholds. We linked collar time series with rectal temperature and respiration rate during two summer periods in a freestall herd equipped with sprinklers and fans. Machine-learning classifiers using rumination variance and drinking-bout frequency detected moderate stress episodes six to ten hours earlier than manual pen walks alone.

Digital dermatitis remains a leading cause of lameness where slatted floors limit dry resting surfaces. Monthly lesion scores and pooled skin swabs from hind feet were analyzed with quantitative PCR for treponeme groups. M2 lesion prevalence correlated with treponeme load more strongly than with herd size, suggesting targeted topical protocols should follow lesion-stage monitoring rather than blanket treatment schedules.

Early detection of subclinical ketosis limits milk loss and displaced abomasum risk. We compared handheld meter readings with laboratory serum concentrations in multiparous cows during the first three weeks postpartum across twelve commercial herds. Agreement within clinical decision thresholds was acceptable for herd-level screening when samples are collected before morning feeding, though repeat testing improves sensitivity for borderline animals.

Intrauterine exposure to amphetamine-type stimulants—most notably methamphetamine—constitutes a developmentally relevant neurotoxic insult with long-lasting consequences for cognition. Both amphetamine and its methylated analogue act on monoamine signaling, maternal cardiovascular function, perfusion of the placenta, and the maturation trajectory of the fetal brain. Convergent findings from longitudinal human cohorts, brain imaging investigations, and experimental animal work indicate that being exposed to methamphetamine before birth tracks with restricted fetal growth, atypical newborn neurobehavior, disturbances within frontostriatal and limbic networks, and downstream weaknesses in attention, response inhibition, learning, memory, and executive control. Results vary between studies, in large part because gestational stimulant use rarely occurs in isolation—it tends to overlap with nicotine, alcohol, cannabis, social disadvantage, undernutrition, and adverse rearing environments. Even so, the accumulating literature points to multiple, interacting routes by which prenatal stimulant exposure may compromise offspring cognition: placental dysfunction, redox imbalance, neuroimmune activation, dysregulated monoamine systems, abnormal synapse formation, microstructural changes in white matter, and durable epigenetic shifts. Here we draw together the contemporary literature on prenatal amphetamine and methamphetamine exposure and the cognitive outcomes that follow, with attention to translational mechanisms, methodological hurdles, and where the field should head next. Stronger prospective cohorts, validated exposure biomarkers, analyses stratified by sex, integrated imaging-and-behavior designs, and early intervention trials will be essential to delineate causal pathways and to lessen the long-term neurodevelopmental toll.

The paper constitutes an analysis of the regional structure or features of the Chinese beef cattle industry, a rarity in academic literature. The development and current status of the industry vary depending on geographical location, regional policy shifts, capital flows and rural labour availability, as well as specific solutions to industry problems, in each region. The study provides an analytical overview of the interplay between China's national rural policy framework and the specific perspectives and assessments of local business actors. The study goes on to evaluate the performance of the country's primary macro-regions, categorised as the Central Plains, North-East, North-West, and South beef cattle areas. The analysis of the development of China's beef cattle industry in each area is presented. The discussion encompassed the regional supply and demand characteristics, as well as the sustainable development concerns pertinent to the industry economy. The relevant policy trends and facts variety was utilised in order to facilitate an evaluation and perspective on the regional development of the beef cattle industry in each macroregion.

Platinum-based antineoplastic drugs, particularly cisplatin, are indispensable in oncology but are notorious for causing debilitating neurological damage driven by inflammation and excessive glutamate signaling. Glucagon-like peptide-1 (GLP-1) analogs, notably semaglutide, have recently drawn significant scientific interest because they shield neurons and suppress inflammatory cascades in various brain injury paradigms. Consequently, we designed the current animal study to investigate if administering semaglutide prior to cisplatin exposure could defend against such neurotoxic outcomes. A total of 40 male Wistar rats were evenly allocated into four distinct groups: a normal Control, a Cisplatin-only group (CIS), a Semaglutide-only group (SMG), and a combination group (CIS+SMG). The chemotherapeutic agent was injected intraperitoneally (5 mg/kg) on the first and fifth days of the protocol. Animals assigned to receive the GLP-1 agonist were given subcutaneous injections (40 μg/kg) exactly three hours prior to the chemotherapy or saline vehicle. Over the span of ten days, we tracked mortality and fluctuations in animal mass. Upon conclusion, we measured the gene expression of key hippocampal glutamate receptors (GluA1, NR2A, and NR2B) via RT-qPCR, and quantified the protein concentrations of crucial inflammatory mediators (IL-6, NF-κB, and TNF-α) using ELISA techniques. The data revealed that cisplatin triggered severe cachexia and reduced lifespan, which coincided with a massive surge in the mRNA levels of the evaluated glutamatergic receptors and a drastic spike in pro-inflammatory proteins. Crucially, prophylactic semaglutide offered no therapeutic benefit. The group receiving the combined treatment exhibited mortality rates and mass depletion that were virtually identical to the group receiving chemotherapy alone. Furthermore, the GLP-1 analog did not normalize the heightened cytokine levels or the elevated receptor transcripts. These outcomes firmly establish that semaglutide cannot counteract the specific neurodegenerative mechanisms triggered by cisplatin, indicating that the neuroprotective traits of GLP-1 analogs are not universally transferable to chemotherapy-related damage. Future research must delineate the precise signaling pathways and receptor mapping within the neural tissues most susceptible to platinum toxicity.

Tyrosine kinase inhibitors (TKIs) occupy a paradoxical position in cognitive medicine. In oncology, several agents have been linked to reversible patient-reported cognitive complaints, whereas in neurodegeneration, selected TKIs show neuroprotective effects in preclinical models and early clinical studies. In this Review, we synthesize evidence across Alzheimer\'s disease, dementia with Lewy bodies, Parkinson\'s disease, and oncology cohorts to argue that cognitive outcome is not determined by TKI class membership but by target profile, blood–brain barrier penetration, dose, disease stage, and endpoint sensitivity. Saracatinib failed in phase 2a Alzheimer\'s disease, nilotinib produced biomarker effects with mixed cognitive readouts in Alzheimer\'s disease and an encouraging cognitive signal in dementia with Lewy bodies, and masitinib met its phase 3 cognitive endpoint despite an elevated adverse-event burden. We propose a precision-translation roadmap built around brain-optimized chemistry, biomarker stratification, central target engagement, and cognition-precise endpoints to advance TKIs toward disease-modifying use in cognitive impairment.

Doxorubicin (DOX) is a widely utilized chemotherapeutic agent recognized for its efficacy against a diverse range of cancers; however, its clinical application is considerably constrained by its hepatotoxic side effects. The liver damage induced by DOX is primarily attributed to oxidative stress and apoptosis. Despite extensive research efforts, there remains a paucity of effective pharmacological interventions to prevent or mitigate DOX-induced liver dysfunction. Sacubitril/Valsartan (VS), an angiotensin receptor neprilysin inhibitor, has exhibited cytoprotective, antioxidant, and anti-apoptotic effects in various organ injury models. Nevertheless, its potential efficacy in ameliorating DOX-induced hepatotoxicity has not been comprehensively explored. To our knowledge, this investigation represents the inaugural study to evaluate the hepatoprotective effects of VS in the context of DOX-induced liver injury. The primary objective of this research was to ascertain the protective efficacy of VS in a rat model of DOX-induced hepatotoxicity. This was achieved by analyzing liver function biomarkers, specifically alanine aminotransferase (ALT), albumin (ALB), and alkaline phosphatase (ALP). Furthermore, the study evaluated oxidative stress markers, including reactive oxygen species (ROS) and malondialdehyde (MDA), as well as key pro-apoptotic signaling pathways, such as caspase-3 and BAX.\nMethods: In this investigation, adult male Wistar rats were systematically divided into four distinct groups: control, VS-treated, DOX-treated, and DOX + VS co-treated. Hepatotoxicity was induced by intraperitoneal administration of DOX at 2.5 mg/kg twice weekly for 2 weeks, resulting in a total dose of 10 mg/kg. Simultaneously, VS was administered orally at a daily dose of 60 mg/kg for the same duration. Liver biochemical markers, including ROS, MDA, caspase-3, BAX, ALT, AST, ALP, and LDH, were measured by ELISA.\nResults: Doxorubicin treatment led to marked increases in ROS, MDA, caspase-3, BAX, ALT, AST, ALP, and LDH, indicating significant liver impairment. Concurrent administration of VS effectively restored normal liver function test results. Moreover, VS substantially reduced oxidative stress, apoptotic activity, and liver enzyme levels compared with doxorubicin treatment alone.

Short-acting β2-agonists (SABAs), especially albuterol/salbutamol, remain essential bronchodilators for rapid relief of acute asthma symptoms. Their safety profile changes, however, when repeated use becomes a substitute for anti-inflammatory therapy. Current guideline strategies discourage SABA-only management and define dispensing of three or more SABA canisters per year as a clinically meaningful risk signal. Recent meta-analytic evidence confirms that SABA overuse is associated with substantially higher risks of acute exacerbations and all-cause mortality, while multinational SABINA analyses demonstrate that overuse is common across asthma severities and health systems. The mechanistic basis of this excess risk is not fully explained by confounding from poor baseline control. The central novelty is the integration of clinical SABA-risk evidence with redox biology and mitochondrial quality-control pathways into a single translational model. In this critical narrative review, we refine and extend a testable hypothesis: chronic or excessive SABA exposure may amplify asthma progression through a feed-forward network involving β2-adrenergic receptor desensitization, reactive oxygen species generation, mitochondrial bioenergetic failure, impaired mitochondrial quality control, and NLRP3 inflammasome activation. We distinguish established clinical evidence from plausible but under-tested mechanistic links, and we propose translational biomarkers and study designs to move the field beyond association. The review concludes that SABA overuse should be treated not merely as a marker of uncontrolled asthma but as a modifiable risk phenotype requiring ICS-containing reliever therapy, structured inhaler-use monitoring, and mechanistic trials of redox- and mitochondria-targeted interventions in carefully phenotyped patients.

Zoonotic diseases represent a significant and growing Zoonotic diseases remain a major and increasing public health concern in the Kingdom of Saudi Arabia (KSA). The country's geographic location, ecological conditions, and sociocultural practices create favorable conditions for the emergence and transmission of zoonotic pathogens in humans. The arid climate of the Arabian Peninsula, traditional livestock husbandry, and extensive cross-border animal trade increase the likelihood of close human–animal contact in this region. Additionally, the annual Hajj and Umrah pilgrimages, which attract millions of international visitors, pose unique challenges to infectious disease surveillance, prevention, and control. This review summarizes the current evidence on viral, bacterial, and parasitic zoonotic diseases reported in Saudi Arabia, with a particular focus on epidemiology, prevalence, transmission dynamics, and associated risk factors. The major zoonotic diseases discussed include Middle East Respiratory Syndrome Coronavirus (MERS-CoV), rabies, Alkhurma hemorrhagic fever virus (AHFV), Crimean–Congo hemorrhagic fever (CCHF), Rift Valley fever (RVF), dengue hemorrhagic fever, West Nile fever, brucellosis, Q fever, cutaneous leishmaniasis, toxoplasmosis, and cystic echinococcosis. This review also highlights the significant role of dromedary camels as reservoirs of several zoonotic pathogens and examines the potential public health implications associated with mass gatherings. Furthermore, this study evaluated the current surveillance systems and control strategies implemented in Saudi Arabia. Strengthening zoonotic disease management through an integrated One Health approach, together with initiatives under Saudi Vision 2030 Health Sector Transformation, will be essential to improve the early detection, preparedness, and coordinated response to emerging zoonotic threats.
