  Phagosomes acquire some hydrolases early during their journey from the cell surface to lysosomes. An example for such hydrolase is cathepsin H which is most concentrated in the early phagosome at a pH of approximately 6.3 (Claus et al., 1998), the pH optimum of enzyme activity (Schwartz and Barrett,

  When skeletal muscle ages, there is an increase in frailty, which is coincident with a decrease in muscle mass and function—this condition is called sarcopenia (Cruz-Jentoft et al., 2010). It has been shown that one of the major pathways downregulated at the onset of sarcopenia is the mitochondrial

  How does the ATM-to-ATR switch occur at DSBs? The progressive attenuation of ATM activation could be attributed to the loss of DNA structures that activate ATM, or to the generation of DNA structures that interfere with ATM activation. Our finding that SSOs do not directly affect the binding of puri

  PD research involves the use of many animal models, which can be categorized into two main types: toxic models—among which the two most widely used are the classical 6-hydroxydopamine (6-OHDA) model in rats and the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model in mice and monkeys—and gen

  2023-10-16

  

  In the pituitary of R. quelen mRNA levels of cyp19a1b were found to be higher in males than females, suggesting a sex-specific function, and perhaps a local action to regulate gonadotropins or other pituitary hormone secretion (Olivereau and Callard, 1985; Zhang et al., 2014). Interestingly, the hig

  l-Arginine supplementation was reported to be efficient, inefficient or toxic in aged patients. The present study does not support our hypothesis that increased tissue arginase activity may account for the ineffectiveness and even the toxicity of l-arginine supplementation in ageing. Indeed, except

  Introduction According to Uganda's Ministry of Health (MOH 2012a:91), intermittent preventive treatment (IPT) to avoid malaria during pregnancy is a free preventive service available to all pregnant women without clinical signs and symptoms of malaria, attending prenatal clinics. However, pregnant

  2023-10-13

  

  The decreased βAR-mediated response has been attributed to different mechanisms, including an attenuation of PKA activation, an impaired generation of cyclic AMP, a reduced receptor density, and a less efficient coupling to adenylyl-cyclase [10]. However, currently there is no single molecular or ce

  Mast cells. Mast 57 100 are immune cells of the myeloid lineage and are ubiquitously present in connective tissues [75]. These cells are involved in the modulation of a number of physiological functions, such as vasodilation, angiogenesis, bacterial, and parasite elimination [75]. Moreover, mast ce

  2023-10-13

  

  Regarding A1Rs and A2ARs, basal conditions generate a low tone of endogenous adenosine and cause A1R activation, in contrast to situations of increased adenosine where A2AR activation becomes dominant. When adenosine concentrations rise, e.g. during hypoxia, also time appears likely important in reg

  Given the powerful and ubiquitous nature of adenosine action within the CNS, basal levels of extracellular adenosine are carefully regulated and are estimated to be in the region of 30–300 nM (Fredholm et al., 2001). The two main pathways for the control of extracellular adenosine involve phosphoryl

  Conclusions Several lines of evidence have been established, which support the adenosine kinase hypothesis of epileptogenesis, which is based on a sequence of events leading from acute 5,8,11-Eicosatriynoic Acid injury to initial downregulation of ADK, rise in extracellular adenosine, changes in

  The role of DHT in early teleost embryogenesis is not entirely clear or established, however additional studies that treat fish embryos to DHT or to specific srd5a inhibitors at critical stages of development (i.e. prior to sex differentiation) will shed light on the early functions of this androgen

  The srd5a isoforms showed unique expression profiles in early FHM development (Fig. 2). Similar to amphibian embryos, there was a high abundance of both srd5a1 and srd5a3 at 1dpf in FHMs, suggesting that mRNA for these enzymes may be maternally deposited and that these enzymes may play a key role in
