Trends in the molecular epidemiology of human papillomavirus in males from the plateau region of Southwest China: an 11-year retrospective analysis (2014-2024).

Background: Persistent high-risk human papillomavirus (HR-HPV) infection may increase the risk of malignancies in males, including penile, rectal, anal, prostate, bladder, and oropharyngeal cancers. However, few studies focused on the epidemiology of human papillomavirus (HPV) in male patients. This study aims to retrospectively investigate the trends of HPV molecular epidemiology in males residing in the plateau region of Southwest China from 2014 to 2024.

Objectives: Antibiotic therapy is widely used for patients with community-acquired pneumonia (CAP), and yet whether the efficacy of antibiotics differs based on the treatment mode remains unclear. This study aimed to summarize the evidence regarding the efficacy and safety of oral vs. parenteral administration of antibiotic therapy for the treatment of patients with CAP.

Liver transplantation for giant hemangioma of the liver: A case report and review of the literature.

Large benign hepatic masses as a rare indication for liver transplantation have been reported less frequently. These liver transplantations are complex, with high intraoperative bleeding, high perioperative complication rates, and high mortality rates due to difficulties in visualization, especially when they have undergone various percutaneous operations or open surgery, resulting in severe perihepatic adhesions. Here is a case report of a patient admitted to our hospital who underwent liver transplantation after suffering from a giant hemangioma in liver transplantation for 10 years and who had received multiple interventional treatments ineffective in the past.

Bidirectionally Regulating Gamma Oscillations in Wilson-Cowan Model by Self-Feedback Loops: A Computational Study.

The Wilson-Cowan model can emulate gamma oscillations, and thus is extensively used to research the generation of gamma oscillations closely related to cognitive functions. Previous studies have revealed that excitatory and inhibitory inputs to the model can modulate its gamma oscillations. Inhibitory and excitatory self-feedback loops are important structural features of the model, however, its functional role in the regulation of gamma oscillations in the model is still unclear.

Oleanolic Acid Inhibits Neuronal Pyroptosis in Ischaemic Stroke by Inhibiting miR-186-5p Expression.

Previous studies have shown that oleanolic acid (OA) ameliorates oxidative injury and cerebral ischaemic damage, and miR-186-5p is verified to be elevated in serum from ischaemic stroke patients. Herein, we investigated whether OA regulates miR-186-5p expression to control neuroglobin (Ngb) levels, thereby inhibiting neuronal pyroptosis in ischaemic stroke.

Isoquercitrin Upregulates Aldolase C Through Nrf2 to Ameliorate OGD/R-Induced Damage in SH-SY5Y Cells.

Isoquercitrin (ISO), an extract from Chinese traditional herb, exhibits potent neuroprotective roles in various disease models. However, its role in stroke is not fully understood. We established oxygen-glucose deprivation and reoxygenation (OGD/R) model in SH-SY5Y cell to study the roles of ISO in stroke.

Dual-Functional Coordination Polymer with High Proton Conductivity and a Low-Detection-Limit Fluorescent Probe.

A coordination polymer with dual functions of high proton conductivity and highly sensitive fluorescent sensors demonstrates a great application potential. In this work, a cadmium-based coordination polymer (denoted as CP ) with hydrothermal stability was synthesized. The abundant coordination water, lattice water, and amino groups make an extended hydrogen-bonding pathway for efficient proton migration, which endows CP with the highest proton conductivity of 2.

The protective effects of yellow tea extract against loperamide-induced constipation in mice.

Yellow tea, a rare type tea from China, has a rich breadth of functional ingredients and benefits the gastrointestinal tract. However, it is not clear whether the yellow tea extract can alleviate constipation. Therefore, we used loperamide-induced constipation in mice to evaluate the effects of yellow tea extract.

Simultaneous Conduction and Valence Band Regulation of Indium-Based Quantum Dots for Efficient H Photogeneration.

Indium-based chalcogenide semiconductors have been served as the promising candidates for solar H evolution reaction, however, the related studies are still in its infancy and the enhancement of efficiency remains a grand challenge. Here, we report that the photocatalytic H evolution activity of quantized indium chalcogenide semiconductors could be dramatically aroused by the co-decoration of transition metal Zn and Cu. Different from the traditional metal ion doping strategies which only focus on narrowing bandgap for robust visible light harvesting, the conduction and valence band are coordinately regulated to realize the bandgap narrowing and the raising of thermodynamic driving force for proton reduction, simultaneously.

Rotaviruses, which are recognized as one of the major etiological agents among infants and young children with diarrhea, consist of three concentric layers of protein capsid with the enclosed double-stranded RNA genome. Rotaviruses infect host cells mainly by identifying the specific receptors on cell surfaces and binding to them. Therefore, receptors are important factors for viruses infecting cells.
