Asiatic acid (AA), a pentacyclic triterpenoid, is a key phytoconstituent of Centella asiatica. AA is a patented as a cytotoxic substance, and it exerts cytotoxicity against Hep3B, Hela and MCF-7 cell lines. However, pentacyclic triterpenoids also modulate the expression and transcriptional activities of Nrf2 and exert cytoprotective effects. In this study, we investigated the effects of AA on the doxorubicin (DXR)-induced organ toxicities and expression of the Nrf2. DXR toxicity was induced by a single intravenous injection of 65...

Prolonged activation and proliferation of hepatic stellate cells (HSCs) usually results in the initiation and progression of liver fibrosis following injury. Recent studies have shown that Substance P (SP) participates in the development of fibrosis. However, whether SP is involved in liver fibrosis, especially in the activation and proliferation of HSCs, is largely unknown. In the present study, we measured the effects of a series of concentrations of SP on the cell viability and activation of HSC-T6 cells and LX2 cells...

Chapalichthys pardalis is a viviparous fish, microendemic to the Tocumbo Region in the state of Michoacán, Mexico. Despite the peculiar type of reproduction of goodeid fish and their mother-embryo interaction, the effects on embryos induced by maternal exposure to aquatic xenobiotics are still unknown. The objective of the present work was to determine the maternal-embryonic metabolic and antioxidant response of C. pardalis exposed to 3,4-dichloroaniline (3,4-DCA), a compound considered highly noxious to the environment because of its high toxicity and persistence, which has been used as reference toxicant in toxicological bioassays...

OBJECTIVE: Clinical neurological assessment is challenging for severe traumatic brain injury (TBI) patients in the acute setting. Waves of neurochemical abnormalities that follow TBI may serve as fluid biomarkers of neurological status. We assessed the cerebrospinal fluid (CSF) levels of glutamate, lactate, BDNF, and GDNF, to identify potential prognostic biomarkers of neurological outcome. METHODS: This cross-sectional study was carried out in a total of 20 consecutive patients (mean [SD] age, 29 [13] years; M/F, 9:1) with severe TBI Glasgow Coma Scale ≤ 8 and abnormal computed tomography scan on admission...

Physical exercise can improve brain function and delay neurodegeneration; however, the initial signal from muscle to brain is unknown. Here we show that the lactate receptor (HCAR1) is highly enriched in pial fibroblast-like cells that line the vessels supplying blood to the brain, and in pericyte-like cells along intracerebral microvessels. Activation of HCAR1 enhances cerebral vascular endothelial growth factor A (VEGFA) and cerebral angiogenesis. High-intensity interval exercise (5 days weekly for 7 weeks), as well as L-lactate subcutaneous injection that leads to an increase in blood lactate levels similar to exercise, increases brain VEGFA protein and capillary density in wild-type mice, but not in knockout mice lacking HCAR1...

BACKGROUND: One of the major causes of mortality in the world is represented by multiple traumas. Thoracic trauma is commonly associated with polytraumas. A series of physiopathological complications follow polytraumas, leading to a significant decrease in the survival rate. As a result of injuries, significant quantities of free radicals (FR) are produced, responsible for oxidative stress (OS). To minimize the effects of OS, we recommend the administration of antioxidant substances. In this study we want to highlight statistically significant correlations between antioxidant therapy and a series of clinical variables...

Genotoxic exposure to chemical substances is common, and nursing mothers could transmit harmful substances or their metabolites to their offspring through breast milk. We explored the possibility of determining genotoxic effects in the erythrocytes of breastfeeding rat pups whose mothers received a genotoxic compound while nursing. Ten groups of female rats and five pups per dam were studied. The control group received sterile water, and the experimental groups received one of three different doses of cyclophosphamide, colchicine, or cytosine-arabinoside...
