This study aimed to evaluate the anti-cancer effects of gedunin, a natural compound, in a rat model of gastric carcinogenesis induced by MNNG. ⋯ Gedunin demonstrates a U-shaped dose-response, with low doses offering protection and high doses promoting tumor growth.

The purpose of this study was to determine whether TLR4 knockdown induced by miRNA-140-5p improves tendinopathy in an in vitro experiment. ⋯ The present results showed that TLR4 knockdown induced by miRNA-140-5p or si-TLR4 improved tendinopathy in an in vitro cell experiment.

A decreased insulin-like growth factor 1 (IGF-1) level has been found in heart failure (HF). There are no reports assessing IGF-2 in HF, although in vitro research has shown that IGF-2 stimulates cardiomyocyte proliferation more than IGF-1. The study aim was to compare the IGF-1 and IGF-2 concentrations depending on HF exacerbation and annual survival. ⋯ Reduced IGF-2 concentration is a better marker of patients with more advanced HF and a higher 1-year death risk than low IGF-1. Its secretion may depend on the cholesterol concentration.

Chronic heart failure (HF) represents a major global public health problem, and despite significant advances in diagnosis and management over the past two decades, HF patients still have a poor prognosis. The aim of the study was to evaluate the relationship between lung congestion, as assessed by lung ultrasonography (LUS), bioimpedance spectroscopy, body fluid compartments, and echocardiographic parameters, and to determine the effect of these associations on all-cause mortality in HF patients. ⋯ We show for the first time in HF patients that pulmonary congestion, as assessed by LUS, is associated with the severity of NYHA class, LVEF, eGFR, and ECW, and it identifies those at increased risk of death.

In the occurrence and development of heat stroke (HS), factors such as hyperthermia, ischemia and hypoxia are essential to the central nervous system (CNS) inflammatory response, but the main mechanism underlying CNS inflammation remains unclear. The aim of the study was to observe the polarization of microglia in response to heat-induced early nerve injury and to explore its possible mechanism of action. ⋯ After heat-induced disease, microglia were found to be active in the brain tissues of dogs. The microglia activated in the early 1-6 h of CNS injury were mainly the M1 type, which were then converted to the M2 type after 6 h. The 24 h M2 type was dominant. The relationship between M1/M2 polarization trends and early brain injury in heat-induced disease may be a key to understanding CNS injury in heat-induced disease.
