How to Detect Porcine Endogenous Retrovirus (PERV) Infections in Patients After Transplantation of Pig Organs.

Porcine endogenous retroviruses (PERVs) are integrated into the genome of all pigs and can infect human cells in culture. However, no PERV infections have been reported in recipients following preclinical or clinical xenotransplantation or deliberate infection experiments. Detection of PERV infection in transplanted recipients is challenging due to microchimerism, such as the presence of pig cells containing PERV proviruses in the recipient.

Lumbosacral transitional vertebrae in small-breed dogs: Prevalence, classification, and characteristics.

The lumbosacral transitional vertebra (LTV) is an abnormally formed vertebra that can be associated with cauda equina syndrome, lumbosacral (LS) degeneration, and pelvic rotation. However, there is little information on LTV in small-breed dogs, and no studies have investigated the association between LTV and LS diseases or degenerative changes in the coxofemoral joints. The purpose of this multicenter, retrospective, and cross-sectional study was to determine the prevalence of LTV in small-breed dogs (<10 kg), classify the type of LTV, and identify its association with degenerative changes in the LS and coxofemoral joints using CT images.

SB16 versus reference denosumab in postmenopausal women with osteoporosis: 18-month outcomes of a phase III randomized clinical trial.

Purpose: This study evaluated the efficacy, safety, pharmacodynamics (PD), pharmacokinetics (PK), and immunogenicity of SB16 versus reference denosumab (DEN) up to 18 months in postmenopausal osteoporosis (PMO) patients, and assessed outcomes after switching from DEN to SB16 compared to those who continued with DEN or SB16.

Methods: 457 PMO patients were initially randomized, with 407 re-randomized at Month 12 to either continue DEN (DEN+DEN), switch to SB16 (DEN+SB16), or continue SB16 (SB16 + SB16) through Month 18. Efficacy was assessed by the percent change from baseline in bone mineral density (BMD) at the lumbar spine, total hip, and femoral neck.

Single-cell analysis reveals expanded CD8 T cells in CSF and shared peripheral clones in sporadic amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that affects motor neurons in the brain and spinal cord. Despite the crucial role of aberrant immune responses in ALS pathogenesis, studies investigating immunological profiles in the cerebrospinal fluid (CSF) of patients with ALS have reported inconsistent findings. Herein, we explored the intrathecal adaptive immune response and features of circulating T cells between CSF and blood of patients with ALS using single-cell RNA and T-cell receptor (TCR) sequencing.

Study for Hydrogen Migration Characteristics in the Elbow of a Hydrogen-Doped Natural Gas Pipeline under Normal Transport and Shutdown Conditions.

During the transportation of hydrogen-doped natural gas (HCNG), there is a risk of uneven distribution of hydrogen at the elbow, causing hydrogen damage to the pipeline. Therefore, based on the basic principles of computational fluid dynamics, this paper uses a hybrid model to describe the flow process of HCNG in an elbow. The results show that under normal transportation, the hydrogen volume fraction varies within 0.

Projecting future excess deaths associated with extreme precipitation events in China under changing climate: an integrated modelling study.

Background: Climate-change-induced extreme precipitation events have attracted global attention; however, the associated excess deaths burden has been insufficiently explored and remains unclear.

Methods: We first defined an extreme precipitation event for each county when the daily total precipitation exceeded the county-specific 99·5th percentile of the daily precipitation from 1986 to 2005; then we estimated the associations between extreme precipitation events and cause-specific deaths in 280 Chinese counties using a two-stage time-series model. Second, we projected the excess deaths related to extreme precipitation events by combining the bias-corrected multi-model precipitation predictions derived under different combined emission-population scenarios of three representative concentration pathways (RCPs; RCP2·6, RCP4·5, and RCP8·5) and three shared socioeconomic pathways (SSP2, a business-as-usual scenario) populations (S1, low fertility rate; S2, medium fertility rate; and S3, high fertility rate).

Research inefficiencies in external validation studies of the Framingham Wilson coronary heart disease risk rule: A systematic review.

Background: External validation studies create evidence about a clinical prediction rule's (CPR's) generalizability by evaluating and updating the CPR in populations different from those used in the derivation, and also by contributing to estimating its overall performance when meta-analysed in a systematic review. While most cardiovascular CPRs do not have any external validation, some CPRs have been externally validated repeatedly. Hence, we examined whether external validation studies of the Framingham Wilson coronary heart disease (CHD) risk rule contributed to generating evidence to their full potential.
