  2024-10-14

  

  Tumor tissues often experience hypoxia owing to accelerated growth rates of malignant cells, accumulation of metabolic products, disorganization of tumor blood vessels, and high interstitial fluid pressures (Makino et al., 2001). In response to AAD treatment, tumor vascular density often decreases t

  2024-10-14

  

  We provide here direct evidences that AT1 receptors are active in ADSCs since Ang II induces intracellular Ca mobilization in these cells. Data obtained during the observation of Ca influxes led us to the search for the ADSCs subpopulation constantly expressing AT1 receptor. ADSCs are necessary for

  First, the complete canonical brain original RAS (Angiotensinogen, Renin, Angiotensin I, Angiotensin Converting Enzyme (ACE), Angiotensin II) has not been conclusively identified in any specific cell type within the brain [1]. Validated evidence for the presence of brain Angiotensinogen and ACE was

  2024-10-14

  

  A number of interesting anti-inflammatory molecules have also been identified that are derived from AA or ω−3 fatty acids, including the lipoxins (for “lipoxygenase interaction products”), resolvins, and protectins [18], [19] (Fig. 1). The lipoxins are synthesized from AA by 5-, 12-, and 15-LOX, as

  2024-10-14

  

  In human epidermoid carcinoma A431 cells, 12-lipoxygenase was significantly increased in glutathione-depleted cells. The relative abundance of phospholipid hydroperoxide versus glutathione peroxidase seems to play an important role in controlling the lipoxygenase reaction [57]. It has been proposed

  Mitochondria from frozen-thawed bull sperm are capable of producing energy using pyruvate and lactate as substrates through oxidative pathways (Beorlegui et al., 1997). Based on the present study, heparin capacitated sperm had a lesser lactate concentration in the incubation medium, supporting the h

  The difference in the mean values of serum ADA in sputum positive PTB and controls was found to be highly significant (P Discussion Tuberculosis is a major health problem in India, and out of all its forms PTB is the commonest. A definite diagnosis of PTB can be made with the presence of Rink Amid

  2024-10-12

  

  Introduction Myasthenia gravis (MG) is an autoimmune disorder characterized by muscle weakness, which is mainly due to autoantibodies reducing the number or function of postsynaptic bruton's tyrosine kinase receptors (AChRs) [1], [2]. Animal models have been developed to uncover the immunopathogen

  Introduction In addition to ATP production, an important role of mitochondria in the pancreatic beta cell is anaplerosis, which is the net synthesis of citric Pyr3 cycle intermediates that are exported to the cytosol where they are converted to numerous other metabolites that stimulate and/or su

  From an historical perspective, ligands for GPCRs (adrenaline, serotonin, TMPyP4 tosylate or morphine, to name a few) have been identified before their receptor counterparts, at a time when the concept of receptor itself was controversial [15]. Although many cognate receptors for endogenous ligands

  We further evaluated the possibility whether letrozole mediates its effect through diverting the pathway towards 5α-DHT and further to 3α-Diol. For this purpose, we measured the concentrations of 5α-DHT and 3α-Diol in mice hippocampus and found that letrozole elevated both 5α-DHT and 3α-Diol levels

  Researchers demonstrated that mitochondria are the main producers of ROS and are the most sensitive to the effects of ROS. Mitochondria-mediated apoptosis may not be limited to the role of cytochrome c in the activation of caspase-3 and ROS may provide an alternate mitochondrial signaling pathway (H
