  Introduction AMPA receptors (AMPARs) mediate the majority of fast excitatory postsynaptic currents (EPSCs) in the mitotic inhibitors (Jonas, 2000). The brevity of EPSCs and rapid deactivation of AMPARs depend upon a short lifetime of synaptically released glutamate, estimated to be about 1 ms (C

  Introduction Our ability to see our surrounding relies directly on the integrity of the anatomical structures composing our eyes. One of these key components is the cornea, consisting of the outer layer of the eye. Its transparency is crucial for light transmission to the retina and allows proper

  Regarding androgens, it is known that they are also essential for reproductive success (Walters et al., 2010). At the molecular level, their effects are produced mainly by dihydrotestosterone (DHT), arising from the conversion of testosterone by the enzyme 3-oxo-5-alpha-steroid-4-dehydrogenase (enco

  The knowledge on the structure of CYP17, including its active site, provides a rationale for understanding many mutations that are found in enzyme dysfunction in clinical disease as well as the enzyme's dual hydroxylase and lyase catalytic capabilities. This knowledge will assist rational drug desig

  Loss of expression or functional activity of cell adhesion is intricately related to advanced stages of tumour progression and invasiveness. Martin-Belmonte and Perez-Moreno recently mentioned that the deregulation of adhesion can alter tumourgenesis in the early stage. We have shown for the first t

  Songbirds are outstanding models in the study of vocal communication (Maney and Pinaud, 2011). Following the pioneering studies of William H. Thorpe and Peter Marler on the development of song in chaffinches (Fringilla coelebs) and white-crowned sparrows (Zonotrichia leucophrys) (Marler, 2004; Thorp

  The functional similarity between GPR25 and APLNR, ie both can be activated by Apelin and Apela and are coupled to Gi-cAMP signaling pathway (Fig. 2, Fig. 3, Fig. 4), strongly suggests that GPR25 signaling may play important physiological and pathological roles in vertebrates more or less similar to

  Recent studies revealed that certain plant-derived compounds can also interfere with AR function. One way of such an interference is by modulating its expression levels. This is the case for the two flavonoids quercetin and luteolin that have been reported to repress the function of AR by inhibiting

  In receptor binding terminology, both receptor and acceptor contain a receptive site for the ligand, although only the receptor induces a biological function. Moreover, the acceptor lacks an endogenous ligand. Many proteins have been described as receptors for toxic Aβ assemblies, implying a designe

  2024-05-06

  

  A characteristic of iron present in brain fluids is considerable differences between measured values of ferritin and transferrin and the total iron content value (Table 1). Variation of the latter is compatible with differences in individual metabolisms. However differences between total iron conten

  Due to metabolic variations, it is important to consider arginine metabolism and dependency in specific contexts to identify precise patterns. This is best illustrated for ASS: while ASS deficiency correlates with worse prognosis in sarcomas, ASS levels positively correlate with a poor prognosis in

  Ethanol can affect biological systems directly, or also through the interactions between these systems, which become important in the actions promoted by alcohol consumption. Its metabolites acetaldehyde and acetate play a key role in the Tanshinone I mediating some effects of ethanol (Israel et al
