Acetylcholinesterase, butyrylcholinesterase and paraoxonase - 1 are glycoproteins that besides regulating the neuromuscular cholinergic system and detoxify the body its activities are risk factors associated with metabolic syndrome (MS). The objective was to evaluate the participation of nicotinamide (NAM) on the activity and glycosylation pattern of circulating esterases in a...
It is well known that signaling mediated by the hepatocyte growth factor (HGF) and its receptor c - Met is involved in the control of cellular redox status and oxidative stress, particularly through its ability to induce hepatoprotective gene expression by activating survival pathways in the hepatocyte. We recently showed...
Cholestasis is a condition associated with a full or partial reduction in the bile flow that reaches the duodenum, caused either by a mechanical blockage impeding the normal flow of bile through the intra an d extrahepatic bile ducts (obstructive cholestasis) or due to alterations on the hepatocellular or ductular...
En este trabajo se utilizó al zigomiceto, Rhizopus oryzae, que fue aislado de un aserradero en Puebla a partir de suelo contaminado con pentaclorofenol (PCF), un xenobiótico de alta persistencia y toxicidad que se encuentra en el medio ambiente. Se ha demostrado que este hongo produce enzimas especializadas, involucradas en...
Se analizó la abundancia, riqueza y diversidad de la herpetofauna del Área Natural Protegida Cuenca Hidrográfica Río Necaxa (ANP - CHRN) en el Estado de Puebla, México. Se aplicó el enfoque metodológico de “ventanas” y para el análisis de la diversidad se utilizó el modelo de partición aditiva. En el...
El género Dictyota posee aproximadamente 78 especies descritas, distribuidas en una gran variedad de ambientes templad os, subtropicales y tropicales. Como en la mayoría de las algas, la sistemática de Dictyota se ha construido principalmente bajo el enfoque del concepto morfológico de especie. Sin embargo, la alta plasticidad fenotípica que...
The aim of the present study was to evaluate the effects of different concentrations of resveratrol on ovine (Ovisaries) oocyte in vitro maturation (IVM) and subsequent embryonic development after handmade cloning (HMC). To determine the effects of resveratrol were evaluated four different concentrations (0, 0 .5, 2 and 5 M)...
En nuestro país el cáncer cérvico - uterino (CCu) es una de las principales causas de mortalidad por cáncer en mujeres, representando el 11.9% de muertes por cáncer. Lamentablemente la falta de políticas de salud provoca que los estadios localmente avanzados prevalezcan en las mujeres mexicanas, por lo que el...
NAFLD is the most common chronic liver disease worldwide, affecting between 25 and 30% of people. The cholesterol overloading in the liver has a toxic effect mainly mediated by ROS generation and is involved in the induction and progression from NAFLD through NASH. Recently, major advance in understanding the NAFLD...
Even though sharks are top predators, there is little information available aimed to understand their habitats, movements and dynamics. Today, there are 1,236 species of chondrichthyan in the world including sharks, rays and chimeras. However, the population and variety of sharks are declining due, mainly, to overfishing. Only in Mexico...
