Skeletal muscle density as a new predictor of abdominal infection in abdominal trauma patients.

Background And Aims: Skeletal muscle density (SMD) is a valuable prognostic indicator in various conditions such as cancer, liver cirrhosis. Yet, the connection between SMD and intra-abdominal infection in individuals who have suffered abdominal injuries is still unclear. The purpose of this research is to examine how well SMD can predict intra-abdominal infection in patients who have suffered abdominal trauma.

Impact of red and blue monochromatic light on the visual system and dopamine pathways in juvenile zebrafish.

Background: The development of the zebrafish visual system is significantly influenced by exposure to monochromatic light, yet investigations into its effects during juvenile stages are lacking. This study evaluated the impacts of varying intensities and durations of red and blue monochromatic light on the visual system and dopamine pathways in juvenile zebrafish.

Methods: Juvenile zebrafish were exposed to red (650 nm) and blue (440 nm, 460 nm) monochromatic lights over four days at intensities ranging from 500 to 10,000 lx, for durations of 6, 10, and 14 h daily.

Targeting mitochondria: a novel approach for treating platinum-resistant ovarian cancer.

Ovarian cancer is a prevalent gynecologic malignancy with the second-highest mortality rate among gynecologic malignancies. Platinum-based chemotherapy is the first-line treatment for ovarian cancer; however, a majority of patients with ovarian cancer experience relapse and develop platinum resistance following initial treatment. Despite extensive research on the mechanisms of platinum resistance at the nuclear level, the issue of platinum resistance in ovarian cancer remains largely unresolved.

A longitudinal study on the development trajectory of auditory processing and its relationship with language development in Chinese preschool children with autism spectrum disorder: study protocol.

Background: It was reported that more than 96% of autism spectrum disorder (ASD) children are accompanied with different degrees of sensory processing abnormalities, and up to 50% of ASD children exhibit abnormal auditory response. Studies have confirmed that some ASD children's abnormal auditory response may be related to their abnormal auditory processing. Prior research demonstrated that ASD children's auditory processing has high heterogeneity, thus, ASD children's auditory processing may have different developmental trajectories.

Targeted gene sequencing and hearing follow-up in 7501 newborns reveals an improved strategy for newborn hearing screening.

Hearing loss is a common congenital condition. Concurrent newborn hearing and limited genetic screening has been implemented in China for the last decade. However, the role of gene sequencing screening has not been evaluated.

Structural and covariance network alterations of the hippocampus and amygdala in congenital hearing loss children.

Objective: The hippocampus and amygdala, as important components of the limbic system, play crucial roles in central remodeling in congenital hearing loss. This study aimed to investigate the morphological integrity and network properties of the subfields of hippocampus and amygdala in children with congenital hearing loss.

Methods: A total of 24 children with congenital hearing loss and 17 age- and sex- matched healthy controls (HC) are included in the study.

A splicing isoform of PD-1 promotes tumor progression as a potential immune checkpoint.

The immune checkpoint receptor, programmed cell death 1 (PD-1, encoded by PDCD1), mediates the immune escape of cancer, but whether PD-1 splicing isoforms contribute to this process is still unclear. Here, we identify an alternative splicing isoform of human PD-1, which carries a 28-base pairs extension retained from 5' region of intron 2 (PD-1^28), is expressed in peripheral T cells and tumor infiltrating lymphocytes. PD-1^28 expression is induced on T cells upon activation and is regulated by an RNA binding protein, TAF15.

Association between the composite dietary antioxidant index and risk of infertility: Evidence from NHANES 2013-2020 and a Mendelian randomization study.

Objective: The Composite Dietary Antioxidant Index (CDAI) measures the antioxidant capacity of the diet, which is believed to provide protection against various diseases, including depression, osteoporosis, and papillomavirus infection, by neutralizing harmful oxidative stress. However, the relationship between CDAI and infertility is not well understood. This research aims to explore the potential correlations between CDAI and the risk of infertility.

The vaginal metabolomics profile with features of polycystic ovary syndrome: a pilot investigation in China.

Background: Polycystic ovary syndrome (PCOS) is the most common metabolic disorder and reproductive endocrine disease, posing an elevated risk to women of reproductive age. Although metabolism differences in serum, amniotic fluid and urine have been documented in PCOS, there remains a paucity of evidence for vaginal fluid. This study aimed to identify the metabolic characteristics and potential biomarkers of PCOS in Chinese women of reproductive age.

The effect of music intervention on depression in perinatal women: A systematic review.

Objective: Perinatal depression has become a global public health problem, which not only harms the health of mothers and their offspring, but also increases the socio-economic burden, so early intervention is urgent. Music intervention is a low-cost and safe intervention method. This study endeavored to systematically integrate and quantitatively evaluate the effectiveness of music intervention for perinatal depression.

A capillary electrophoresis-based assay for carrier screening of the hotspot mutations in the gene.

Molecular genetic analysis of the cytochrome P450 family 21 subfamily A member 2 () gene is challenging owing to the highly homologous with its pseudogene. A reliable approach for the large-scale population screening of is required. This study aimed to establish and evaluate a capillary electrophoresis-based assay for hotspot mutation carrier screening of the gene.

Taurine hypomodification underlies mitochondrial tRNATrp-related genetic diseases.

Escherichia coli MnmE and MnmG form a complex (EcMnmEG), generating transfer RNA (tRNA) 5-carboxymethylaminomethyluridine (cmnm5U) modification. Both cmnm5U and equivalent 5-taurinomethyluridine (τm5U, catalyzed by homologous GTPBP3 and MTO1) are found at U34 in several human mitochondrial tRNAs (hmtRNAs). Certain mitochondrial DNA (mtDNA) mutations, including m.

Serum and Fecal Metabolite Profiles Linking With Gut Microbiome in Triple-Negative Breast Cancer Patients.

Background: Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by poor prognosis due to the absence of effective targeted therapies. Emerging evidence indicates that the gut microbiota and its metabolites play a key role in the occurrence and development of TNBC. This study aimed to explore the metabolic changes and potential mechanisms associated with TNBC.

Early-Life Gut Microbiota: A Possible Link Between Maternal Exposure to Non-Nutritive Sweeteners and Metabolic Syndrome in Offspring.

Metabolic syndrome (MetS) is recognized as a group of metabolic abnormalities, characterized by clustered interconnected traits that elevate the risks of obesity, cardiovascular and atherosclerotic diseases, hyperlipidemia, and type 2 diabetes mellitus. Non-nutritive sweeteners (NNS) are commonly consumed by those with imbalanced calorie intake, especially in the perinatal period. In the past, accumulating evidence showed the transgenerational and mediated roles of human microbiota in the development of early-life MetS.

Establishment of age-specific reference intervals for serum 25-hydroxyvitamin D in a large pediatric population of Nanjing, China.

Background: The reference intervals (RIs) is defined as the central 95 % range of reference values from healthy individuals. The establishment of appropriate medical RIs for specific populations is crucial for accurate diagnosis and treatment of disease. However, the RIs for 25-hydroxyvitamin D (25(OH)D) in Chinese pediatric individuals are currently not available.
