aim: was to assess the effects of ramadan observance upon repeated sprints and associated inflammatory and oxidative stress responses. methods: ten young trained boxers were tested during a control period (c), at the end of the first week (r-1), and during the fourth week of ramadan observance (r-4). on each occasion, they performed three vertical jumps, 10 x 6 s repeated sprints on a cycle erg...

one of the most important problems in neuroscience researches is the understanding what is the communication between the immune system and central nervous system. proinflammatory factors play an important role in this communication. the dysregulation of proinflammatory factors such as cytokines and chemokines is a central feature in the development of neuroinflammation.one of the important  cyt...

INTRODUCTION Previous studies show that mercury exposure increases cardiovascular risk, although the underlying cellular mechanisms have still not been fully studied. The aim of this project is to study, in vascular fibroblasts (VF), the effect of HgCl2 exposure on the expression of enzymes involved in the synthesis of prostanoids and reactive oxygen species (ROS). These molecules have been sho...

β-Hydroxybutyric acid (BHBA) has neuroprotective effects, but the underlying molecular mechanisms are unclear. Microglial activation plays an important role in neurodegenerative diseases by producing several proinflammatory enzymes and proinflammatory cytokines. The current study investigates the potential mechanisms whereby BHBA affects the expression of potentially proinflammatory proteins by...

BACKGROUND Microglial activation plays an important role in neurodegenerative diseases by producing several proinflammatory enzymes and proinflammatory cytokines. The phenolic glucoside gastrodin, a main constituent of a Chinese herbal medicine, has been known to display anti-inflammatory properties. The current study investigates the potential mechanisms whereby gastrodin affects the expressio...

The study of ENT cancer allows the implementation of molecular biology methods in diagnosis, predicting the evolution of the disease and suggesting a certain treatment. MMPs are proteolytic enzymes, zinc dependent endopeptidases, secreted by tissues and proinflammatory cells that play a role in the clearance of cell surface receptors. They are expressed as zymogens (inactive forms). Proteolytic...

Interleukin 1β (IL-1β) and tumor necrosis factor α (TNF-α) are key cytokines that drive the production of inflammatory mediators and matrix-degrading enzymes in osteoarthritis (OA). These proinflammatory cytokines bind to their respective cell surface receptors and activate inflammatory signaling pathways culminating with the activation of nuclear factor κB (NF-κB), a transcription factor that ...

Aim: was to assess the effects of Ramadan observance upon repeated sprints and associated inflammatory and oxidative stress responses. Methods: Ten young trained boxers were tested during a control period (C), at the end of the first week (R-1), and during the fourth week of Ramadan observance (R-4). On each occasion, they performed three vertical jumps, 10 x 6 s repeated sprints on a cycle erg...

The incidence and severity of mastitis can be high during the period of transition from pregnancy to lactation when dairy cattle are susceptible to oxidative stress. Oxidative stress may contribute to the pathogenesis of mastitis by modifying the expression of proinflammatory genes. The overall goal of this study was to determine the relationship between critical antioxidant defense mechanisms ...
