  2025-01-10

  

  A disruption of lung barrier function caused by PM2.5 has been observed in our experiments; however the underlying mechanism has not been investigated. Zhao et al. (2018) reported that PM2.5 down-regulated the expression levels of tight junction (TJ) proteins and resulted in nasal epithelial barrier

  Conflicts of interest Introduction Arginase catalyzes the reaction in which l-arginine is converted to l-ornithine and urea. In humans, two arginase isoenzymes have been identified, arginase 1 and arginase 2, that differ in cellular location and tissue distribution [1]. Both arginase enzymes a

  2025-01-10

  

  The basis for the protonation of chitosan is the alkaline primary amino group, which is also the reason for the special properties of chitosan (Guibal, Van Vooren, Dempsey, & Roussy, 2006; Tamer et al., 2017; Yang et al., 2014). Our previous work (Meng et al., 2012) and several other reports (Yan et

  2025-01-10

  

  Androgen receptor translocates from the cytoplasm to the nucleus after binding to its ligands (Quigley et al., 1995). In the current study, although propofol did not significantly affect total androgen receptor protein levels, it significantly decreased nuclear androgen receptor levels. These findin

  2025-01-10

  

  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

• Corticosterone induced inhibition of OCT mediated transport

  2025-01-10

  

  Corticosterone-induced inhibition of OCT-mediated transport is rapid and appears to involve direct interaction of the steroid with the transporter at a specific site. Volk et al. (2003) studied OCT2-mediated transport by measuring substrate-induced currents using patch clamp of Xenopus oocytes exoge

  In patients with spina bifida and spinal cord injury, fecal incontinence is a serious issue that can impair activities of daily living and patient self-esteem. To address this Malone et al. first described the Antegrade Continence Enema (ACE) procedure in 1990 [1], which achieves continence by all

  2025-01-10

  

  It has been reported that leukotrienes and their receptors, e.g. the cysteinyl leukotriene receptor 1 (CysLT1) may promote cAMPS-Rp, triethylammonium salt mg injury (Ding et al., 2007) and that increased 5-LOX expression and activity lead to production of brain-toxic molecules (Khan et al., 2010).

  Several 16-dehidropregnenolone derivatives functionalized at C3, C4, C5 and C6 (Fig. 7) were prepared and evaluated as 5α-reductase inhibitors bearing in mind that after the formation of an enzyme-steroid complex a nucleophilic portion of the enzyme attacks the double bond of the steroid through Mic

  Autophagy is finalized through the coordinated positioning and fusion of autophagosomes with lysosomes, during which an array of common and specific membrane traffic-associated proteins is mobilized. Among these proteins, small GTPases, like Rab7, Rab34, or Arl8, and their STF 31 proteins, regulate

  2025-01-09

  

  Another important question concerns the mechanism by which a polyubiquitinated substrate is released from the Cdc48 complex and passed on to downstream components, such as the proteasome. There are at least three proposed models. In the first, a ubiquitinated substrate is transferred by ubiquitin-bi

  Among the most important Ca regulatory mechanisms are the Plasma Membrane Calcium ATPase (PMCA) and Sarcoplasmic Reticulum Calcium ATPase (SERCA). These pumps belong to the family of P-ATPases, which share the formation of an acid-stable phosphorylated intermediate as part of their reaction cycle. P

  Aromatization of the pyrrole ring after anion capturing, using acceptor atoms with electron deficiency (B & Be), and substitution of strong electron withdrawing groups such as CN were three strategies used to design a new class of anion receptors. Comparison of the anion affinities of these anion re

  In 2010, a study highlighted the usefulness of arginase-1 as a sensitive and specific marker of hepatocytic differentiation for diagnostic pathology [9]. Subsequent studies have validated the high sensitivity and specificity of arginase-1, in particular its added value in evaluating poorly different
