Associations of the Geriatric Nutritional Risk Index with high risk for prostate cancer: A cross-sectional study.

Objectives: The geriatric Nutritional Risk Index (GNRI) is an effective tool to assess the nutritional status of the elderly. However, the relationship between the GNRI and the risk for prostate cancer (PCa) remains uncertain in middle-aged and older men. The aim of this study was to investigate the association between the GNRI and the risk for PCa by analyzing the serum total (tPSA) and free prostate-specific antigen (fPSA) levels (including percent fPSA [%fPSA]).

Potential protective effects of Huanglian Jiedu Decoction against COVID-19-associated acute kidney injury: A network-based pharmacological and molecular docking study.

Corona virus disease 2019 (COVID-19) is prone to induce multiple organ damage. The kidney is one of the target organs of SARS-CoV-2, which is susceptible to inducing acute kidney injury (AKI). Huanglian Jiedu Decoction (HLJDD) is one of the recommended prescriptions for COVID-19 with severe complications.

Management of urinary incontinence after radical cystectomy and orthotopic neobladder: A scoping review of international practices.

Objectives: To identify and describe international practice in incontinence management after radical cystectomy and orthotopic neobladder.

Materials And Methods: A systematic scoping review following the methodology of the Joanne Briggs Institute was conducted in which the application searched 15 data sources to identify papers published in English, from 1979 to 2022.

Results: Of the 16 papers that met the eligibility criteria, articles in Eastern countries mainly focus on the effect of conservative treatment, while in Western countries, more attention is paid to the effect of surgical treatment.

Molecular genetic characteristics of thymic epithelial tumors with distinct histological subtypes.

Background: Due to the low incidence and histological heterogeneity, the molecular features and underlying carcinogenic mechanisms of thymic epithelial tumors (TETs) are yet to be fully elucidated, especially for different subtypes of TETs.

Methods: Tumor tissue samples of 43 TETs with distinct histological subtypes were collected. We analyzed the molecular characteristics in different subtypes based on whole exome sequencing data.

Metformin Suppresses Hepatocellular Carcinoma through Regulating Alternative Splicing of LGR4.

Methods: First, the expression of LGR4 in HCC tumor tissues and cell lines was detected by western blotting and immunofluorescence. The ability of cell proliferation, migration, and invasion was detected with CCK8, wound-healing, and transwell assays when overexpressing LGR4 or treating with metformin. The -catenin expression was detected by immunofluorescence.

PGE2 pathway mediates oxidative stress-induced ferroptosis in renal tubular epithelial cells.

Prostaglandin E2 (PGE2) is one of the most abundant prostaglandins and has been implicated in various diseases. Here, we aimed to explore the role of the PGE2 pathway in mediating ferroptosis during acute kidney injury. When renal tubular epithelial cells stimulated by H O , the contents of glutathione (GSH) and glutathione peroxidase 4 (GPX4) decreased, whereas the level of lipid peroxide increased.

15-Hydroxyprostaglandin Dehydrogenase Is a Predictor of Stroke-Associated Pneumonia.

Background And Purpose: Stroke is a serious fatal and disabling disease. Stroke-associated pneumonia (SAP) is the most common complication of stroke, which may further aggravate the stroke. The prevention and early prediction of SAP is a key clinical strategy.

Trans-activation of eotaxin-1 by Brg1 contributes to liver regeneration.

Infiltration of eosinophils is associated with and contributes to liver regeneration. Chemotaxis of eosinophils is orchestrated by the eotaxin family of chemoattractants. We report here that expression of eotaxin-1 (referred to as eotaxin hereafter), but not that of either eotaxin-2 or eotaxin-3, were elevated, as measured by quantitative PCR and ELISA, in the proliferating murine livers compared to the quiescent livers.

Protective effect of HS on LPS‑induced AKI by promoting autophagy.

The present study explored the protective effect of exogenous hydrogen sulfide (HS) on lipopolysaccharide (LPS)‑induced acute kidney injury (AKI) and the underlying mechanisms. To establish an AKI injury mouse model, LPS (10 mg/kg) was intraperitoneally injected into mice pretreated with 0.8 mg/kg sodium hydrosulfide hydrate (NaHS), an HS donor.

COX-2/PGE2 Pathway Inhibits the Ferroptosis Induced by Cerebral Ischemia Reperfusion.

Cerebral ischemia reperfusion (I/R) injury easily develops in ischemic stroke, resulting in more serious injury. Ferroptosis is involved in cerebral I/R injury, but the mechanism remains unclear. Prostaglandin E2 (PGE2) is potential to regulate ferroptosis.

WD-40 repeat protein 26 protects against oxidative stress-induced injury in astrocytes via Nrf2/HO-1 pathways.

Background: Stroke is the leading cause of disability and the third leading cause of death in the world, and no effective treatment has been developed. Oxidative stress-induced cell injury and genomic instability is implicated in the pathogenesis of stroke, whose prognosis remains poor.

Methods: A model of cerebral ischemic/reperfusion injury model was established through four artery occlusions.

Surgical treatment and operation time in human immunodeficiency virus-negative cryptococcal meningitis.

There are still no unified guidelines of surgical treatment and timing for human immunodeficiency virus (HIV)-negative patients with cryptococcal meningitis (CM).The clinical data and follow-up data were collected from HIV-negative CM patients in Xiangya Hospital of Central South University from January 2009 to November 2018, and 42 patients who were treated with surgical intervention were enrolled in the present study. These 42 patients were divided into ventriculoatrial (VA) group, ventriculoperitoneal group, external ventricle drainage (EVD) group, hydrocephalus (HYC) group, non-HYC group, EVD group, and non-EVD group (VA/ ventriculoperitoneal) according to different surgical procedures.

Regulation of PGE Pathway During Cerebral Ischemia Reperfusion Injury in Rat.

Stroke is an acute central nervous system disease with high morbidity and mortality rate. Cerebral ischemia reperfusion (I/R) injury is easily induced during the development or treatment of stroke and subsequently leads to more serious brain damage. Prostaglandin E (PGE) is one of the most important inflammatory mediators in the brain and contributes to both physiological and pathophysiological functions.

Pharmacologic Blockade of 15-PGDH Protects Against Acute Renal Injury Induced by LPS in Mice.

Prostaglandin pathway plays multiple roles in various physiological and pathological conditions. The present study aimed to investigate the effect of 15-hydroxyprostaglandin dehydrogenase (15-PGDH), a key enzyme in the degradation of prostaglandins, on lipopolysaccharide (LPS)-induced acute kidney injury (AKI) in mice. In this study, male C57BL/6J mice were injected intraperitoneally with LPS (10 mg/kg).

Dynamic expression and roles of sequestome‑1/p62 in LPS‑induced acute kidney injury in mice.

Acute kidney injury (AKI) is one of the most common complications of sepsis. The roles of autophagy in AKI have been demonstrated in previous studies. Sequestosome‑1 (p62) has been demonstrated to serve essential roles in autophagy.

The Effects of Resveratrol on Inflammation and Oxidative Stress in a Rat Model of Chronic Obstructive Pulmonary Disease.

Oxidative stress and inflammation are hypothesized to contribute to the pathogenesis of chronic obstructive pulmonary disease (COPD). Resveratrol (trans-3,5,4'-trihydroxystilbene) is known for its antioxidant and anti-inflammatory properties. The study aimed to investigate the effects of resveratrol in a rat model with COPD on the regulation of oxidative stress and inflammation via the activation of Sirtuin1 (SIRTl) and proliferator-activated receptor-γ coactivator-1α (PGC-1α).

Aggravation of acute kidney injury by mPGES-2 down regulation is associated with autophagy inhibition and enhanced apoptosis.

The deletion of microsomal prostaglandin E synthase-2 (mPGES-2) does not affect in vivo PGE production, and the function of this enzyme remains unknown until now. This study investigated the expression and roles of mPGES-2 in LPS induced acute kidney injury (AKI) both in vitro and in vivo. We found that mPGES-2 was up-regulated in kidney of mice with LPS induced AKI.
