Cardiomyopathy, a heterogeneous pathological condition characterized by changes in cardiac structure or function, represents a significant risk factor for the prevalence and mortality of cardiovascular disease (CVD). Research conducted over the years has led to the modification of definition and classification of cardiomyopathy. Herein, we reviewed seven of the most common types of cardiomyopathies, including Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC), diabetic cardiomyopathy, Dilated Cardiomyopathy (DCM), desmin-associated cardiomyopathy, Hypertrophic Cardiomyopathy (HCM), Ischemic Cardiomyopathy (ICM), and obesity cardiomyopathy, focusing on their definitions, epidemiology, and influencing factors.

Article Synopsis
  • - This study investigates the role of ferroptosis in spinal cord injury (SCI) using a rat model, revealing significant changes in gene expression related to ferroptosis at various time points post-injury.
  • - One day after SCI, there was increased expression of specific ferroptosis and oxidative stress markers, suggesting this period is crucial for understanding ferroptosis progression in spinal cord damage.
  • - The research identified key hub genes involved in ferroptosis and proposed ten potential compounds that may help repair SCI by targeting this process, alongside constructing a network of related RNAs to better understand the underlying mechanisms.

Recent studies in patients with spinal cord injuries (SCIs) have confirmed the diagnostic potential of biofluid-based biomarkers, as a topic of increasing interest in relation to SCI diagnosis and treatment. This paper reviews the research progress and application prospects of recently identified SCI-related biomarkers. Many structural proteins, such as glial fibrillary acidic protein, S100-β, ubiquitin carboxy-terminal hydrolase-L1, neurofilament light, and tau protein were correlated with the diagnosis, American Spinal Injury Association Impairment Scale, and prognosis of SCI to different degrees.

Background: Clinical tolerance to trastuzumab greatly affects the therapeutic effect in breast cancer (BC). Long-chain non-coding RNA (lncRNA) plays an important role in the development of trastuzumab resistance, in which SNHG7 can promote the epithelial mesenchymal transformation (EMT) of breast cancer cells into, while EMT is related to trastuzumab resistance of breast cancer cells.

Objective: To investigate whether lncRNA-SNHG7 can enhance chemotherapy resistance and cell viability of BC cells by regulating miR-186.

Snakes have numerous features distinctive from other tetrapods and a rich history of genome evolution that is still obscure. Here, we report the high-quality genome of the five-pacer viper, Deinagkistrodon acutus, and comparative analyses with other representative snake and lizard genomes. We map the evolutionary trajectories of transposable elements (TEs), developmental genes and sex chromosomes onto the snake phylogeny.

Objective: To investigate the risk factors and angiographic features of acute coronary syndrome (ACS) in women below 50 years of age.

Methods: A total of 131 women with ACS aged 50 years or younger were enrolled in this study as the case group, with another 425 women aged below 50 years with normal coronary angiographic findings as the control group. The risk factors and clinical and coronary angiographic features of ACS were analyzed.

Placental deficiencies are related to the developmental abnormalities of transgenic cattle produced by somatic cell nuclear transfer, but the concrete molecular mechanism is not very clear. Studies have shown that placental development can be regulated by microRNAs (miRNAs) in normal pregnancy. Thus, this study screened differentially expressed miRNAs by the next-generation sequencing technology to reveal the relationship between miRNAs expression and aberrant development of placentae produced by the transgenic-clone technology.

A sub-acute toxicity test was performed to investigate the effects of molybdenum (Mo) on ovarian function. ICR adult female mice were exposed to Mo by free access to distilled water containing the Mo at 5, 10, 20, and 40 mg/L for 14 days. Compared to the control group, M II oocyte morphology, ovary index, and ovulation improved within the 5 mg/L Mo group, but were negatively affected by Mo at 40 mg/L.

In order to investigate the effects of molybdenum (Mo) on sperm parameters and testicular oxidative stress, the ICR strain of adult mice were exposed to different doses of molybdenum for a sub-acute toxicity test. Compared to the control, our results showed that the sperm parameters, including the epididymis index, sperm motility, sperm count, and morphology, increased by a moderate dose of Mo (25 mg/L), but were negatively affected at high doses (≥ 100 mg/L). In addition, the changes of sperm parameters were accompanied with changes of the superoxide dismutase (SOD) activities, the glutathione peroxidase (GPx) activities, and the malondialdehyde (MDA) levels in testes.
