Delayed endometrial preparation for the induction of luteolysis as a potential factor for improved reproductive performance in Angus beef heifers with high antral follicle counts.

Antral Follicle Count (AFC) and anti-Müllerian hormone (AMH) concentrations are reflective for ovarian reserve and have been associated with improved reproductive performance in cattle. Key events for regulation of uterine receptivity are orchestrated by progesterone. As progesterone concentrations are greater in animals with high than low AFC, we tested the hypothesis, if the resulting improved uterine environment will lead to improved conceptus elongation and endometrial response to interferon tau.

Scope: Curcumin (Cur), with diverse pharmacological properties, shows anti-obesity, immunomodulatory, and anti-inflammatory effects. Its role in ulcerative colitis complicated by obesity remains unclear.

Methods And Results: Here, colitis is induced in obese mice using dextran sulfate sodium (DSS), followed by administration of Cur at a dosage of 100 mg kg for 14 days.

Sishen pills inhibit inflammatory dendritic cell differentiation via miR-505-3p mediated E-cadherin downregulation in ulcerative colitis.

Background: Ulcerative colitis (UC) is an autoimmune disease that is highly susceptible to recurrence, which is still a lack of effective drugs with minor side effects in clinic. Intervention of inflammatory differentiation of dendritic cells (DCs) might be an effective strategy to treat UC. Sishen Pills (SSP) is a classic Chinese herbal formula which has been demonstrated the protective effect of UC, but the mechanism remains unclear.

Methods for Screening and Isolating Extremely Heat-Resistant from Meat Sources.

Meat animals harbor diverse populations in their digestive tracts and can serve as sources of pathogenic . The consumption of meat and produce contaminated with virulent from animal sources is associated with human illnesses and outbreaks. Heat treatment is an antimicrobial intervention that is commonly used during meat processing to ensure effective reductions in microbial load.

Immune mRNA Expression and Fecal Microbiome Composition Change Induced by Djulis ( Koidz.) Supplementation in Aged Mice: A Pilot Study.

: The aging process has always been associated with a higher susceptibility to chronic inflammatory lung diseases.

Telomere-to-telomere assemblies of cattle and sheep Y-chromosomes uncover divergent structure and gene content.

Reference genomes of cattle and sheep have lacked contiguous assemblies of the sex-determining Y chromosome. Here, we assemble complete and gapless telomere to telomere (T2T) Y chromosomes for these species. We find that the pseudo-autosomal regions are similar in length, but the total chromosome size is substantially different, with the cattle Y more than twice the length of the sheep Y.

Cecal necroptosis triggers lethal cardiac dysfunction in TNF-induced severe SIRS.

Tumor necrosis factor (TNF) induces systemic inflammatory response syndrome (SIRS), and severe SIRS can serve as a model for studying animal death caused by organ failure. Through strategic cecectomy, we demonstrate that necroptosis in the cecum initiates the death process in TNF-treated mice, but it is not the direct cause of death. Instead, we show that it is the cardiac dysfunction downstream of cecum damage that ultimately leads to the death of TNF-treated mice.

Stub1 promotes degradation of the activated Diaph3: A negative feedback regulatory mechanism of the actin nucleator.

The formin protein Diaph3 is an actin nucleator that regulates numerous cytoskeleton-dependent cellular processes through the activation of actin polymerization. Expression and activity of Diaph3 is tightly regulated: lack of Diaph3 results in developmental defects and embryonic lethality in mice, while overexpression of Diaph3 causes auditory neuropathy. It is known that Diaph3 homophilic interactions include the intramolecular interaction of its Dia-inhibitory domain (DID)-diaphanous autoregulatory domain (DAD) domains and the intermolecular interactions of DD-DD domains or FH2-FH2 domains.

Evaluation of Methods for Identifying Poultry Wing Rinses With Salmonella Concentrations Greater Than or Equal to 10 CFU/mL.

In the United States, the Proposed Regulatory Framework to Reduce Salmonella Illnesses Attributable to Poultry published by the Food Safety and Inspection Service (FSIS) has highlighted the need for simple, rapid methods that identify poultry wing rinse samples harboring Salmonella concentrations ≥10 CFU/mL. One of eight cold-stressed and nutrient-starved Salmonella strains was inoculated into post-chill two-joint poultry wing rinses (48 turkey and 72 chicken) at levels from 0.22 to 3.

Formononetin ameliorates dextran sulfate sodium-induced colitis via enhancing antioxidant capacity, promoting tight junction protein expression and reshaping M1/M2 macrophage polarization balance.

Ulcerative colitis (UC) is a complex, refractory inflammatory bowel disease characterized impared intestinal mucosal barrier and imbalanced M1/M2 macrophage polarization mediating its progression. Formononetin (FN), a bioactive isoflavone with established anti-inflammatory and immunomodulatory properties, shows promise in mitigating UC, yet its therapeutic and underlying mechanisms remain unclear. In this study, colitis was induced in mice by administering 2.

Mammalian genome research resources available from the National BioResource Project in Japan.

Mammalian genome research has conventionally involved mice and rats as model organisms for humans. Given the recent advances in life science research, to understand complex and higher-order biological phenomena and to elucidate pathologies and develop therapies to promote human health and overcome diseases, it is necessary to utilize not only mice and rats but also other bioresources such as standardized genetic materials and appropriate cell lines in order to gain deeper molecular and cellular insights. The Japanese bioresource infrastructure program called the National BioResource Project (NBRP) systematically collects, preserves, controls the quality, and provides bioresources for use in life science research worldwide.

LOX-mediated ECM mechanical stress induces Piezo1 activation in hypoxic-ischemic brain damage and identification of novel inhibitor of LOX.

Hypoxic-ischemic encephalopathy (HIE) poses a significant challenge in neonatal medicine, often resulting in profound and lasting neurological deficits. Current therapeutic strategies for hypoxia-ischemia brain damage (HIBD) remain limited. Ferroptosis has been reported to play a crucial role in HIE and serves as a potential therapeutic target.

Deciphering Mutational Impacts on c-Src-HK2 Interaction in Colorectal Cancer Progression, and Identification of Potential Phytocompounds Inhibitors: A Molecular Simulation and Free Energy Calculation Approach.

Background: Colorectal cancer (CRC) stands as the third most widespread cancer worldwide in both men and women, witnessing a concerning rise, especially in younger demographics. Abnormal activation of the Non-Receptor Tyrosine Kinase c-Src has been linked to the advancement of several human cancers, including colorectal, breast, lung, and pancreatic ones. The interaction between c-Src and Hexokinase 2 (HK2) triggers enzyme phosphorylation, significantly boosting glycolysis, and ultimately contributing to the development of CRC.

AOPPs induces EMT and fibrosis by activating oxidative stress through ERK/p38 MAPK signaling pathway in endometriosis.

Epithelial-mesenchymal transition (EMT) is known to play a crucial role in the development of endometriosis (EMs). However, the exact mechanisms involved in EMT regulation in EMs are not well understood. In this study, we performed comprehensive research using clinical samples, single-cell sequencing, and in vivo/in vitro models to investigate the effects of advanced oxidation protein products (AOPPs) on EMT and the underlying mechanisms in EMs.
