Polyamines Protect Porcine Sperm from Lipopolysaccharide-induced Mitochondrial Dysfunction and Apoptosis via Casein Kinase 2 Activation.

Bacterial contamination is an inevitable issue during the processing of semen preservation in pigs. As a prototypical endotoxin from Gram-negative bacteria in semen, lipopolysaccharide (LPS) undermines sperm function during liquid preservation. Spermine and spermidine could protect cells against LPS-induced injury, and the content of spermine and spermidine in seminal plasma is positively correlated with sperm quality.

A fluorescent probe based on pyrazoline with significant Stokes shifts for the detection of Cu ions and its applications.

A simple pyrazoline derivative BBD has been synthesized for detecting Cu in EtOH/HEPES (v/v = 1 : 1, pH = 7). The probe has high selectivity for Cu by quenching the fluorescence intensity and was sensitive to pH. When excited at 398 nm, fluorescence is emitted at 520 nm with a Stokes shift of 122 nm, which is larger than that of other reported pyrazoline skeleton probes.

SARS-CoV-2 ORF8 drives osteoclastogenesis in preexisting immune-mediated inflammatory diseases.

Patients with immune-mediated inflammatory diseases (IMIDs) like rheumatoid arthritis (RA) are at higher risk for severe COVID-19 and long-term complications in bone health. Emerging clinical evidence demonstrated that SARS-CoV-2 infection reduces bone turnover and promotes bone loss, but the mechanism underlying worsened bone health remains elusive. This study sought to identify specific immune mediators that exacerbated preexisting IMIDs after SARS-CoV-2 exposure.

New thermoplastic poly(ester-ether) elastomers with enhanced mechanical properties derived from long-chain dicarboxylic acid for medical device applications.

Recent advances in medical plastics highlight the need for sustainable materials with desirable elastic properties. Traditional polyester elastomers have been used as alternatives to polyvinyl chloride (PVC) due to their biocompatibility and adjustable mechanical properties. However, these materials often lack the necessary stability and toughness for reliable medical applications.

Advances in the detection technology of vegetable soil borne fungi and bacteria.

Soil borne diseases are one of the most serious diseases which often results the decline of vegetables quality and loss of production. Moreover, it is difficult for plants to exhibit disease symptoms in the early stages attributing to strong concealment of soil borne pathogens. Therefore, early detection of pathogens and their physiological races plays an important role in reducing the harm of pathogens associated with diseases of vegetable crops.

Shikonin induces the apoptosis and pyroptosis of EGFR-T790M-mutant drug-resistant non-small cell lung cancer cells via the degradation of cyclooxygenase-2.

Background: The T790M mutation in the epidermal growth factor receptor (EGFR) gene is the primary cause of resistance to EGFR-tyrosine kinase inhibitor (TKI) therapy in non-small cell lung cancer (NSCLC) patients. Previous research demonstrated that certain traditional Chinese medicine (TCM) monomers exhibit anti-tumor effects against various malignancies. This study aims to investigate the potentials of shikonin screened from a TCM monomer library containing 1060 monomers in killing EGFR-T790M drug-resistant NSCLC cells and elucidate the underlying mechanisms.

Development and validation of a predictive model for metabolic syndrome in a large cohort of people living with HIV.

Background: The global prevalence of metabolic syndrome (MetS) in people living with HIV (PLWH) is on the rise in the post era of antiretroviral therapy (ART). Nevertheless, there are no validated predictive models available for assessing the risk of MetS in this specific population.

Methods: This study included PLWH who participated in annual follow-ups at Southern Medical University Nanfang Hospital from September 2022 to November 2023.

iTRAQ proteomic analysis of exosomes derived from synovial fluid reveals disease patterns and potential biomarkers of Osteoarthritis.

Exosomes extracted from synovial fluid (SF-exo) reflect the status of their originating cells. The proteomic profiles of SF-exo are important for the diagnosis of osteoarthritis (OA). To delineate the proteomic differences between SF-exo from OA patients and healthy individuals, a quantitative proteomic study based on iTRAQ technology was performed.

Bacteria-activated macrophage membrane coated ROS-responsive nanoparticle for targeted delivery of antibiotics to infected wounds.

Bacterial infections and antibiotic resistance represent significant global public health challenges, necessitating the development of innovative antibacterial agents with targeted delivery capabilities. Our study utilized macrophages' natural ability to recognize bacteria and the increased reactive oxygen species (ROS) at infection sites to develop a novel nanoparticle for targeted delivery and controlled release. We prepared bacteria-activated macrophage membranes triggered by Staphylococcus aureus (Sa-MMs), which showed significantly higher expression of Toll-like receptors (TLRs), compared to normal macrophage membranes (MMs).

Immediate weight bearing as tolerated versus delayed weight bearing following intramedullary fixation for geriatric intertrochanteric fractures: a post hoc analysis.

Background: Early weight bearing is crucial for fracture healing after osteosynthesis for intertrochanteric fractures (ITFs). The optimal period to start weight bearing after surgery is still under debate. The aim of this study was to compare immediate weight bearing (IWB) as tolerated with delayed weight bearing (DWB) following intramedullary fixationin elderly ITF patients.
