The Effect of Glyphosate on Human Sperm: In Vitro Approximation

Introduction Glyphosate is an herbicide used to eradicate illicit crops; however, its use is controversial due to different health problems associated with it. The present study aims to evaluate the effects of glyphosate on human sperm in vitro. Methods Twenty-two semen samples from healthy normozoos...

Polyphenolic extracts of walnut (Juglans regia) green husk containing juglone inhibit the growth of HL-60 cells and induce apoptosis

BACKGROUND: Juglone is a naphthoquinone currently obtained by chemical synthesis with biological activities including antitumor activity. Additionally, juglone is present in the green husk of walnut, which suggests evaluating the effect of GH extracts on carcinogenic cell lines. RESULTS: Walnut green hus...

Vitexin induces apoptosis through mitochondrial pathway and PI3K/Akt/mTOR signaling in human non-small cell lung cancer A549 cells

Biol. Res; 52 (), 2019
BACKGROUND: Currently, the prognosis of patients with non-small cell lung cancer (NSCLC) remains dismal; hence, it is critical to identify effective anti-NSCLC agents with limited side effects. This study aimed to evaluate the therapeutic potential of flavonoid compound vitexin in human NSCLC cells and t...

Introducción La infertilidad por factor masculino afecta al 30% de las parejas infértiles y la evaluación seminal es crítica en las determinaciones que conllevan a un posible tratamiento con el fin de tener un resultado exitoso. Objetivo El objetivo de este estudio fue evaluar la relación que ex...

Hydrogen sulfide protects H9c2 cardiomyoblasts against H2O2-induced apoptosis

Braz. j. med. biol. res; 52 (4), 2019
Reactive oxygen species (ROS) are highly reactive chemical species that may cause irreversible tissue damage, and play a critical role in cardiovascular diseases. Hydrogen sulfide (H2S) is a gasotransmitter that acts as a ROS scavenger with cardio-protective effects. In this study, we investigated the cy...

Impact of sodium butyrate and mild hypothermia on metabolic and physiological behaviour of CHO TF 70R cells

Background: To reduce costs associated with productivity of recombinant proteins in the biopharmaceutical industry, research has been focused on regulatory principals of growth and survival during the production phases of the cell culture. The main strategies involve the regulation of cell proliferation ...

Autophagy protects against neural cell death induced by piperidine alkaloids present in Prosopis juliflora (Mesquite)

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Prosopis juliflora is a shrub that has been used to feed animals and humans. However, a synergistic action of piperidine alkaloids has been suggested to be responsible for neurotoxic damage observed in animals. We investigated the involvement of programmed cell death (PCD) and autophagy on the m...

Cadmium-induced apoptosis of Siberian tiger fibroblasts via disrupted intracellular homeostasis

Biol. Res; 49 (), 2016
BACKGROUND: Heavy metals can cause great harm to Siberian tigers in the natural environment. Cadmium (Cd2+) is an environmental contaminant that affects multiple cellular processes, including cell proliferation, differentiation, and survival. It has been shown to induce apoptosis in a variety of cell typ...

Efecto de los factores solubles de Staphylococcus aureus, Staphylococcus capitis y Staphylococcus epidermidis sobre la funcionalidad espermática
Effect of soluble factors of Staphylococcus aureus, Staphylococcus capitis and Staphylococcus epidermidis on sperm functionality

ANTECEDENTES: La interacción entre los espermatozoides con algunas especies bacterianas o sus factores solubles influyen en el deterioro de la calidad seminal, alterando la función reproductiva del hombre. OBJETIVO: El objetivo de este trabajo fue determinar el efecto de los factores solubles de Staphy...

Selección espermática en semen congelado/descongelado de equino: evaluación de las membranas plasmática, acrosomal y potencial de membrana mitocondrial

Int. j. morphol; 32 (2), 2014
Los procedimientos de criopreservación inducen cambios morfofuncionales en los espermatozoides. Es importante post descongelación espermática utilizar procedimientos de selección que permitan recuperar espermatozoides altamente funcionales. El objetivo del presente estudio fue comparar la eficiencia ...
