The D-lactate enigma: exploring the inflammatory influence of D-lactate in cattle.

D-lactic acidosis is associated with fermentative disturbances and is often marked by elevated levels of D-lactic acid in the blood, ruminal fluid, and synovial fluid in cattle. D-lactic acidosis is linked to various inflammatory manifestations, and although the causative factors have been extensively explored, the exact pathogenesis of the associated inflammation remains elusive. Notably, less attention has been given to D-lactate, a stereoisomer found in the plasma of affected animals, which may lead to D-lactic acidosis.

Soluble Antigen (Ag)-Induced NETs Under Hypoxic Conditions Exert Cytotoxic Effects on Hepatic Cells In Vitro.

is a parasitic trematode that causes fasciolosis in sheep, provoking a decrease in their reproductive capacity, weight gain, meat and milk production, and wool quality. In the pathogenesis of , the penetration and migration of parasitic stages through the liver provoke intense inflammatory immune responses and tissue damage. The aim of this study was to investigate the cytotoxic effects of -induced ovine NETs in exposed hepatocytes in vitro, and to analyze whether antigens (Ag) trigger the release of ovine NETs under hypoxic conditions as well as the roles of matrix metalloproteinase-9 (MMP-9) and CD11b in this cellular process in vitro.

Obesity uncovers presence of inflammatory lung macrophage subsets with adipose tissue transcriptomic signature in influenza virus infection.

Obesity is a risk factor for increased lung damage and disease severity during influenza virus infection. White adipose tissue (WAT) inflammation is a key driver of disease pathogenesis in obesity. Whether and how obesity modifies lung and WAT immune cell character and function in obesity to amplify influenza disease severity remains unknown.

Linoleic Acid Induces Metabolic Reprogramming and Inhibits Oxidative and Inflammatory Effects in Keratinocytes Exposed to UVB Radiation.

Linoleic acid (LA), the primary ω-6 polyunsaturated fatty acid (PUFA) found in the epidermis, plays a crucial role in preserving the integrity of the skin's water permeability barrier. Additionally, vegetable oils rich in LA have been shown to notably mitigate ultraviolet (UV) radiation-induced effects, including the production of reactive oxygen species (ROS), cellular damage, and skin photoaging. These beneficial effects are primarily ascribed to the LA in these oils.

Determinants of Thoroughbred yearling sales price in the UK.

Background: Industry-level figures suggest that up to two-thirds of Thoroughbred breeding operations in the UK are unprofitable and that around half of sales transactions of Thoroughbred yearlings, commercial breeders' predominant income source, return a loss. The industry strategy currently endorses investment in stallion covering fee; however, to date, a comprehensive evaluation of sales price determinants in the UK setting is lacking and could better inform economic decision making to improve profitability.

Methods: Sales catalogue and Weatherbys' stud book data from all Thoroughbred yearlings sold at the 2020 Tattersalls October yearling sale in the UK were used to build a hedonic sales price model.

Late cognitive and adaptive outcomes of patients with neuroblastoma-associated opsoclonus-myoclonus-ataxia-syndrome: A report from the Children's Oncology Group.

Background: Opsoclonus-myoclonus-ataxia syndrome (OMAS) is a rare autoimmune disorder of the nervous system presenting with abnormal eye and limb movements, altered gait, and increased irritability. Two to four percent of children diagnosed with neuroblastoma have neuroblastoma-associated OMAS (NA-OMAS). These children typically present with non-high-risk neuroblastoma that is cured with surgery, with or without chemotherapy.

Metabolic causes of liver disease among adults living with HIV from low- and middle-income countries: a cross-sectional study.

Introduction: Liver disease is a leading cause of morbidity and mortality among persons living with HIV (PLHIV). While chronic viral hepatitis has been extensively studied in low- and middle-income countries (LMICs), there is limited information about the burden of metabolic disorders on liver disease in PLHIV.

Methods: We conducted a cross-sectional analysis of baseline data collected between October 2020 and July 2022 from the IeDEA-Sentinel Research Network, a prospective cohort enrolling PLHIV ≥40 years on antiretroviral treatment (ART) for ≥6 months from eight clinics in Asia, Americas, and central, East, southern and West Africa.

Andrographolide Ameliorates Inflammatory Changes Induced by D-Lactate in Bovine Fibroblast-like Synoviocytes.

During acute ruminal acidosis, the manifestation of aseptic polysynovitis and lameness in cattle has been observed. Evidence suggests that joint inflammation can be attributed to the metabolic alterations induced by D-lactate in fibroblast-like synoviocytes (FLSs). We aimed to investigate whether andrographolide could mitigate the inflammation and metabolic alterations induced by D-lactate in bovine fibroblast-like synoviocytes (bFLSs).

A Genetic Tool to Identify Predators Responsible for Livestock Attacks in South America and Recommendations for Human-Wildlife Conflict Mitigation.

Livestock predation induces global human-wildlife conflict, triggering the retaliatory killing of large carnivores. Although domestic dogs () contribute to livestock depredation, blame primarily falls on wild predators. Dogs can also transmit pathogens between wildlife, domestic animals, and humans.

Neural tube defects and epigenetics: role of histone post-translational histone modifications.

Neural tube defects (NTDs) are the most common congenital anomalies of the CNS. It is widely appreciated that both genetic and environmental factors contribute to their etiology. The inability to ascribe clear genetic patterns of inheritance to various NTD phenotypes suggests it is possible that epigenetic mechanisms are involved in the etiology of NTDs.

Prophylactic lymphedema surgery in lower limb soft tissue sarcomas: A clinical paradigm in a promising field.

Introduction: Oncological treatments, such as radiotherapy and surgery, are high-risk factors for the development of secondary lymphedema in the upper and lower limbs, as well as the genitalia. Prophylactic lymphedema surgery (PLS) has previously demonstrated promising results in reducing secondary lymphedema in breast cancer and urogenital cancer patients. We conducted a study to adapt this principle for patients with lower-extremity sarcomas.
