Background And Aims: While the therapeutic promise of anti-inflammatory interventions for obesity-associated cardiomyopathy is well recognized, clinically effective targeted therapies remain to be developed. Here, through systematic anti-inflammatory screening, we elucidated both the therapeutic efficacy and mechanistic basis of a novel indole-substituted acetamide derivative (compound #3) in mitigating obesity-induced cardiomyopathy.

Methods: A high-fat diet (HFD)-induced obese mouse model was used to evaluate the cardioprotective efficacy of compound #3.

To study the effects of metabolic enzyme activity inhibition and genetic polymorphisms on the pharmacokinetics and pharmacodynamics of rivaroxaban, we established an in vitro enzymatic reaction system to screen for inhibitors, and used the UPLC-MS/MS method to detect the levels of rivaroxaban and its metabolite M2-1. Additionally, in vivo pharmacokinetic-pharmacodynamic studies were conducted using Sprague-Dawley rats. Human recombinant CYP2J2 baculosomes were prepared using a baculovirus-insect expression system to investigate the impact of genetic polymorphisms on rivaroxaban metabolism through enzyme kinetics methods.

Spontaneous intracerebral hemorrhage (ICH) is a prevalent hemorrhagic stroke characterized by a significant fatality rate and severe neurological impairments. Stress hyperglycemia has been confirmed to have a significant prognostic role in a range of diseases. However, studies on the association between stress hyperglycemia and the outcome of ICH have not currently been reported.

Objective: A pilot study to evaluate the correlation between multimodal imaging features and the expression of the human epidermal growth factor receptor type 2 (HER-2) in breast cancer to provide a basis for clinical treatment and prognosis evaluation.

Methods: We included a total of 62 patients with breast cancer admitted to the Affiliated Hospital of Hebei University between 2018 and 2022. All of them underwent the relevant investigations, including ultrasound, mammography, and enhanced magnetic resonance imaging (MRI), in the hospital within one month before surgery or biopsy.

Article Synopsis
  • Neuroimaging studies show that sleep deprivation (SD) disrupts brain functional connectivity (FC), but traditional analysis methods have limitations that can lead to inconsistent findings.
  • The current study employed a data-driven, whole brain voxel-based approach to assess 52 young adults, revealing significant changes in connectivity, particularly in the default mode network (DMN) and limbic network after SD.
  • Results indicate that the right precuneus is crucial for FC disturbances linked to wakefulness, offering potential avenues for interventions against sleep deprivation effects.

Article Synopsis
  • * Out of over 100 tested drugs, sertraline and duloxetine were found to effectively inhibit erdafitinib's metabolism, increasing its levels in the blood and enhancing anti-tumor effects when used in lower doses.
  • * The combination of erdafitinib with these drugs not only maintained its effectiveness against tumors but also reduced harmful side effects, suggesting a promising new approach for improving treatment outcomes in cancer therapy.

Article Synopsis
  • * Low concentrations of HS were found to enhance EGC function by increasing mitochondrial membrane potential, reducing apoptosis markers (BAX and caspase-3), and promoting cell proliferation, while high concentrations had detrimental effects.
  • * Honokiol treatment provided protective benefits to EGCs under high HS conditions by modulating apoptosis and improving calcium response, ultimately supporting colonic motility through the Bcl2/BAX/caspase-3 pathway and Cx43 expression.

Background: The prevalence of hypertensive heart disease (HHD) is high and there is currently no easy way to detect early HHD. Explore the application of radiomics using cardiac magnetic resonance (CMR) non-enhanced cine sequences in diagnosing HHD and latent cardiac changes caused by hypertension.

Methods: 132 patients who underwent CMR scanning were divided into groups: HHD (42), hypertension with normal cardiac structure and function (HWN) group (46), and normal control (NOR) group (44).

With the rapid development of single-molecule sequencing (SMS) technologies, the output read length is continuously increasing. Mapping such reads onto a reference genome is one of the most fundamental tasks in sequence analysis. Mapping sensitivity is becoming a major concern since high sensitivity can detect more aligned regions on the reference and obtain more aligned bases, which are useful for downstream analysis.

Motivation: Longer reads produced by PacBio or Oxford Nanopore sequencers could more frequently span the breakpoints of structural variations (SVs) than shorter reads. Therefore, existing long-read mapping methods often generate wrong alignments and variant calls. Compared to deletions and insertions, inversion events are more difficult to be detected since the anchors in inversion regions are nonlinear to those in SV-free regions.

Altricial birds often display biased preferences in providing parental care for their dependent offspring, especially during food shortages. During this process, such inflexible rules may result in provisioning errors. To demonstrate how parents optimize their provisioning strategies, we proposed a "diagnosis model" of parental care to posit that parents will undergo a diagnosis procedure to test whether selecting against some particular offspring based on phenotype is an optimal strategy.

Dimeric pyruvate kinase (PK) M2 (PKM2) plays an important role in promoting the accumulation of hypoxia-inducible factor (HIF)-1α, mediating aberrant glycolysis and inducing fibrosis in diabetic kidney disease (DKD). The aim of this work was to dissect a novel regulatory mechanism of Yin and Yang 1 (YY1) on lncRNA-ARAP1-AS2/ARAP1 to regulate EGFR/PKM2/HIF-1α pathway and glycolysis in DKD. We used adeno-associated virus (AAV)-ARAP1 shRNA to knocked down ARAP1 in diabetic mice and overexpressed or knocked down YY1, ARAP1-AS2 and ARAP1 expression in human glomerular mesangial cells.
