The immune regulatory role of exosomal miRNAs and their clinical application potential in heart failure.

Heart failure (HF) is a complex and debilitating condition characterized by the heart's inability to pump blood effectively, leading to significant morbidity and mortality. The abnormality of immune response is a key factor in the progression of HF, contributing to adverse cardiac remodeling and dysfunction. Exosomal microRNAs (miRNAs) play a pivotal role in regulating gene expression and cellular function, which are integral to the crosstalk between cardiac and immune cells, influencing immune cell functions, such as macrophage polarization, T cell activity, and cytokine production, thereby modulating various pathological processes of HF, such as inflammation, fibrosis, and cardiac dysfunction.

Neuroticism and asthma: Mendelian randomization analysis reveals causal link with mood swings and BMI mediation.

Background: Neuroticism has been associated with asthma, but the nature of this relationship remains unclear due to limited understanding of the impact of psychological factors on asthma risk. While Neuroticism is known to affect various health outcomes, its specific role in respiratory conditions like asthma is not fully understood.

Methods: We conducted Mendelian randomization (MR) analyses using genome-wide association studies (GWAS) to explore the causal link between 12 Neuroticism traits and asthma.

The association between endometrial polyps and insulin resistance from the expression of PI3K and AKT proteins perspective.

Background: Insulin resistance (IR) induces hyperinsulinemia, which activates downstream signaling pathways such as the phosphatidylinositol-3-kinase/protein kinase B (PI3K/AKT) pathway, ultimately leading to abnormal proliferation and apoptosis of endometrial cells. This is thought to be a key pathogenic mechanism underlying the development of endometrial polyps (EP). This study aims to investigate the relationship between IR and the development of EP, the expression levels of downstream signaling molecules, including PI3K and AKT, and related laboratory parameters were examined.

Genotype diversity and antibiotic resistance risk in Aeromonas hydrophila in Sichuan, China.

Sichuan is a significant aquaculture province in China, with a total aquaculture output of 1.72 × 10 tons in 2022. One of the most significant microorganisms hurting the Sichuan aquaculture is Aeromonas hydrophila, whose genotype and antibiotic resistance are yet unknown.

Effect of interval time between hysterosalpingography and intrauterine insemination on the pregnancy outcome of infertile patients.

Background: Hysterosalpingography (HSG) is the most commonly applied tubal patency test in clinical practice. Although some studies have found an increased pregnancy rate after HSG, no studies to date have specifically characterized the effect of interval time between HSG and IUI on pregnancy outcome.

Objectives: To investigate the effect of interval time between HSG and intrauterine insemination (IUI) on live birth rates of infertile patients.

Identification, Biological Function Profiling and Biosynthesis of Secondary Metabolites in Medicinal Orchids.

The secondary metabolites present in medicinal orchids are diverse and possess a vast array of biological activities. They represent valuable raw materials for modern pharmaceuticals and clinical medicine and have tremendous potential for future development. A systematic collation of secondary metabolites' composition and a summary of the biological activities of medicinal orchids represent a crucial step in unlocking the potential of these valuable resources in drug development.

Oncogenic SIRT7 inhibits GATA4 transcriptional activity and activates the Wnt signaling pathway in ovarian cancer.

Objective: Sirtuin-7 (SIRT7) is a class III histone deacetylase that plays an important role in cancer development and frequently overexpressed in carcinomas. In this study, the tumor-supporting role and underlying mechanisms of SIRT7 were characterized in ovarian cancer (OC) aggressiveness.

Methods: SIRT7 expression was examined in OC tissues and cells.

Temporospatial Expression of Neuropeptide Substance P in Dental Pulp Stem Cells During Odontoblastic Differentiation in Vitro and Reparative Dentinogenesis in Vivo.

Introduction: Substance P (SP) is a neuropeptide released from the nervous fibers in response to injury. In addition to its association with pain and reactions to anxiety and stress, SP exerts various physiological functions by binding to the neurokinin-1 receptor (NK1R). However, the expression and role of SP in reparative dentinogenesis remain elusive.

Construction of a New Dual-Responsive Nano-Drug Delivery System for Matrix Metalloproteinases and Adenosine Triphosphate in Ovarian Cancer Using Nanomicelles.

In this manuscript we constructed a dual-responsive nano-drug delivery system for matrix metalloproteinases and ATP in ovarian cancer microenvironment. The nanomicelle PCL-DNA/DOX-Peptide-PEG was prepared by intercalating doxorubicin hydrochloride between C and G base pairs of DNA double helix structure. Another ATP-responsive nanomicelle PCL-DNA/DOX-PEG was prepared.

Design of two-dimensional diffractive optical elements for beam shaping of multicolor light-emitting diodes.

To achieve a cellular network in visible light communication, the illumination areas covered by red, green, and blue light-emitting diodes (LEDs) forming a white LED should be of the same size with uniform intensity distribution. In this paper, the iterative algorithm for the design of multicolor-oriented two-dimensional diffractive optical elements (DOEs) is improved. Simulation results indicate that almost the same size of the diffraction patterns of the DOE illuminated by multicolor LEDs is achieved with good uniformity of the intensity distribution.

Differentiated regulation of immune-response related genes between LUAD and LUSC subtypes of lung cancers.

Lung squamous cell carcinoma (LUSC) and lung adenocarcinoma (LUAD) are the two major subtypes of lung cancer, with LUSC exhibits faster progression rate than LUAD. To investigate the roles of immune-response related genes (IRGs) in lung cancer progression, we used LUAD and LUSC samples at different cancer progression stages, and identified that the expression profiles of IRGs could serve as a better classification marker for cancerous tissues of both LUAD and LUSC. We found that the expression changes of IRGs were different between LUAD and LUSC.

Diffractive optical element with same diffraction pattern for multicolor light-emitting diodes.

The wavelength-division multiplexing technique can be utilized in visible light communication to increase the channel capacity when a multicolor mixed white LED is used as light source. In such an application, the illumination area of LEDs should be invariant to the incident wavelength, so as to decrease interference within the adjacent regions. Diffractive optical elements (DOEs) can be used in the optical transmitter system to shape the diffraction patterns into polygons.
