Beta-aminoisobutyric acid improves bovine oocyte maturation and subsequent embryonic development by promoting lipid catabolism.

Energy metabolism homeostasis is essential for oocyte maturation and acquisition of developmental capacity. However, bovine oocyte in vitro maturation (IVM) is highly susceptible to metabolic stress and lipid accumulation. β-Aminoisobutyric acid (BAIBA), a metabolite produced in response to skeletal muscle exercise, has been reported to be involved in lipid and glucose metabolism, as well as inflammation and oxidative stress.

Effects of Astaxanthin on the Physiological State of Porcine Ovarian Granulose Cells Cultured In Vitro.

The physiological state of Granulosa cells (GCs) is intricately linked to the growth and development of oocytes. Oxidative stress has been found to cause damage to GCs in vitro. Astaxanthin (AST), a well-known natural ketone-type carotenoid, has demonstrated strong antioxidant properties.

Efficacy, Safety, and Immunogenicity of Subunit Respiratory Syncytial Virus Vaccines: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background: Respiratory syncytial virus (RSV) is garnering increasing attention, with a growing number of subunit RSV vaccines under active clinical investigation. However, comprehensive evidence is limited.

Methods: We conducted a comprehensive search across PubMed, Embase, the Cochrane Library, Web of Science, and ClinicalTrials.

Effects of salinity and betaine addition on anaerobic granular sludge properties and microbial community succession patterns in organic saline wastewater.

In this study, the effects of different salinity gradients and addition of compatible solutes on anaerobic treated effluent water qualities, sludge characteristics and microbial communities were investigated. The increase in salinity resulted in a decrease in particle size of the granular sludge, which was concentrated in the range of 0.5-1.

Coactosin-Like Protein 1 (COTL1) Could Be an Immunological and Prognostic Biomarker: From Pan-Cancer Analysis to Low-Grade Glioma Validation.

Background: Cancer represents a widespread global health challenge impacting millions of individuals worldwide. Identifying new targets for cancer treatment is a crucial step in developing more effective therapies. Among these potential targets, Coactosin-like protein 1 (COTL1), a cytoskeleton-associated protein with critical roles in cell migration, adhesion, and signaling, has shown involvement in tumor progression.

Effects of Dexmedetomidine Combined with Intravenous Anesthesia on Oxidative Stress Index, Postoperative Sleep Quality, and Brain Function in HICH Patients.

To investigate the effects of dexmedetomidine combined with intravenous anesthesia on oxidative emergency indicators, postoperative sleep quality, and brain function in patients with hypertensive cerebral hemorrhage (HICH), a total of 285 HICH patients admitted to our hospital from February 2020 to February 2021 were selected. The combined anesthesia group ( = 142) and the control group ( = 143) were established by the random number table method. The control group received conventional intravenous anesthesia, and the combined anesthesia group received dexmedetomidine combined intravenous anesthesia.

The role of MOZ/KAT6A in hematological malignancies and advances in MOZ/KAT6A inhibitors.

Hematological malignancies, unlike solid tumors, are a group of malignancies caused by abnormal differentiation of hematopoietic stem cells. Monocytic leukemia zinc finger protein (MOZ), a member of the MYST (MOZ, Ybf2/Sas3, Sas2, Tip60) family, is a histone acetyltransferase. MOZ is involved in various cellular functions: generation and maintenance of hematopoietic stem cells, development of erythroid cells, B-lineage progenitors and myeloid cells, and regulation of cellular senescence.

[Role and mechanism of histone deacetylases in mouse neuronal development].

Objective: To study the role and mechanism of histone deacetylase 1 (HDAC1) and histone deacetylase 2 (HDAC2) in mouse neuronal development.

Methods: The mice with Synapsin1-Cre recombinase were bred with mice to obtain the mice with neuron-specific conditional knockout (knockout group), and their littermates without knockout were used as the control group. The general status of the mice was observed and survival curves were plotted.

Fermentation of high-salt liquid-state soy sauce without any additives by inoculation of lactic acid bacteria and yeast.

Food additives are artificial or natural substances that are added to food to improve the color, aroma, taste, and other qualities, and to meet processing requirements. For the concern of food health and safety, brewed soy sauce without additives has attracted consumers' attention. Here, only four necessary raw materials including soybean, wheat, salt, and water were added.

pPolyHb protects myocardial H9C2 cells against ischemia-reperfusion injury by regulating the Pink1-Parkin-mediated mitochondrial autophagy pathway.

Mitochondrial dysfunction is a major contributory factor for myocardial ischemia-reperfusion (I/R) injury. It has been reported that Pink1-Parkin-mediated mitochondrial autophagy could effectively remove damaged mitochondria and excess ROS to ensure the stability of intracellular mitochondria. The present study was designed to evaluate whether the polymerized porcine haemoglobin (pPolyHb), a novel type of haemoglobin oxygen carrier, has an effect on I/R injury via regulating the Pink1-Parkin mediated mitochondrial autophagy pathway in myocardial H9C2 cells.

Association between polymorphisms of MIR17HG and risk of colorectal cancer in the Chinese Han population.

Background: Colorectal cancer is the third most common cancer worldwide. Recently, an increasing number of evidences suggest that genetic susceptibility plays an important role in the occurrence of colorectal cancer. This study aimed to better understand the influence of MIR17HG polymorphisms on colorectal cancer susceptibility in the Chinese Han population.

Shikonin induces apoptosis and prosurvival autophagy in human melanoma A375 cells via ROS-mediated ER stress and p38 pathways.

Shikonin, a botanical drug extracted from Lithospermum erythrorhizon, exhibits anti-cancer effects in various cancer cell lines. However, the mechanisms underlying these effects have not been completely elucidated yet. Here, we showed that Shikonin induces apoptosis and autophagy in A375 cells and inhibits their proliferation.

Study of the pharmacokinetics of polymerized porcine hemoglobin (pPolyHb).

Polymerized porcine hemoglobin (pPolyHb), a kind of glutaraldehyde-polymerized haemoglobin-based oxygen carrier, was developed as a potential red blood substitute for clinical applications. Assessment of its absorption, distribution, and metabolism is a major determinant of its safety and efficacy. In this study, a series of pharmacokinetic parameters of pPolyHb were measured and calculated in different animal models, such as the top-load model, the 50% exchange transfusion model and the haemorrhagic shock model.

Structural and Biochemical Analysis of Tyrosine Phosphatase Related to Biofilm Formation A (TpbA) from the Opportunistic Pathogen Pseudomonas aeruginosa PAO1.

Biofilms are important for cell communication and growth in most bacteria, and are responsible for a number of human clinical infections and diseases. TpbA (PA3885) is a dual specific tyrosine phosphatase (DUSP) that negatively regulates biofilm formation in the opportunistic pathogen Pseudomonas aeruginosa PAO1 by converting extracellular quorum sensing signals into internal gene cascade reactions that result in reduced biofilm formation. We have determined the three-dimensional crystal structure of wild-type TpbA from P.

Insights into the structure and architecture of the CCR4-NOT complex.

The CCR4-NOT complex is a highly conserved, multifunctional machinery with a general role in controlling mRNA metabolism. It has been implicated in a number of different aspects of mRNA and protein expression, including mRNA degradation, transcription initiation and elongation, ubiquitination, and protein modification. The core CCR4-NOT complex is evolutionarily conserved and consists of at least three NOT proteins and two catalytic subunits.
