BACKGROUND Glomerular damage in IgA nephropathy (IgAN) is mediated by complement activation via the alternative and lectin pathways. Therefore, we focused on molecules stabilizing and regulating the alternative pathway C3 convertase in urine which might be associated with IgAN pathogenesis. METHODS Membrane attack complex (MAC), properdin (P), factor H (fH) and Complement receptor type 1 (CR1...
Several features of activation of mouse peritoneal macrophages were elicited by 1-2-d exposure to submicrogram concentrations of anti-Mac-1 (M1/70), a rat monoclonal antibody that reacts with the alpha chain of complement receptor type 3 (Mac-1). The changes induced included enhanced capacity to secrete H2O2 when triggered with PMA, decreased secretion of proteins, increased expression of Ia an...
In Mobile WiMAX, the power saving mechanism (PSM), which operates alternately in sleep and awake modes, works to extend the lifetime of mobile stations (MSs), though it concurrently induces a medium access control (MAC) service data unit (SDU) response delay. In this paper, we derive the analytical models for two of the most important performance metrics: the average power consumption and the a...
In this study, activated carbon (AC) and magnetic (MAC) were prepared from Dalbergia sissoo sawdust for the removal of antibiotic Azithromycin (AZM) aqueous solution. The effect initial concentration, contact time, pH, adsorbent dosage, temperature investigated both adsorbents. optimum AZM pH adsorbents dosages found to be 80 mg/L, 120 min, 6 7 (pH, respectively, AC MAC), 0.1 g (for respectivel...
مطالعه حاضر با هدف بررسی اثرات شمارش یاختههای پیکری (scc)، scc افتراقی (ماکروفاژ (mac)، لیمفوسیت (lym) و لوکوسیتهای چندهستهای (pmn))، تعداد و مرحله شیردهی بر ترکیب شیر در شیر شتر و گاو صورت گرفته است. شیر شتر به طور معنیداری (05/0>p) حاوی مواد معدنی بیشتری است. سطح لیپولیز در شیر شتر مشابه شیر گاو است. سطح لیپولیز همگام با افزایش سطح mac در شیر شتر افزایش یافته ولی در شیر گاو چنین نیست. نتا...
It has been well established that human mononuclear phagocytes have the capacity to produce 1,25-dihydroxy-vitamin D3 [1,25(OH)3D3] and express the vitamin D receptor (VDR). However, 1 alpha-hydroxylase activity and VDR receptor expression during differentiation of monocytes (MO) into mature macrophages (MAC) have not been previously examined. The in vitro maturation of blood MO can serve as a ...
High-density glasses of neodymio-cadmium lead borate chemical composition xNd2O3/20CdO/20PbO/(57-x)B2O3/3Na2O, where (0 (0Nd) ? x 5 (5Nd) wt%) have been fabricated by a melt quenching process. Physical, structure properties as well gamma-radiation and neutron shielding effectiveness in wide photon energy range 0.015–15 MeV examined. The amorphous nature xNd-glasses was confirmed, there lack the...
BACKGROUND Gamma-aminobutyric acid type A receptor potentiation and/or N-methyl-d-aspartate (NMDA) receptor inhibition might explain the anesthetic properties of fluorinated aromatic compounds. We hypothesized that depression of dorsal horn neuronal responses to noxious stimulation would correlate with the magnitude of effect of benzene (BNZ), o-difluorobenzene, and hexafluorobenzene (HFB) on N...
Bovine mastitis caused by Escherichia coli has traditionally been viewed as a transient infection. However, E. coli can also cause clonal persistent intramammary infection (IMI) in dairy cows. In this study, we explored the possibility that E. coli strains associated with persistent IMI are better able to adhere to, invade, survive and replicate in cultured mammary epithelial cells (MAC-T) than...
BACKGROUND The activity of canine expiratory neurons is primarily dependent on N-methyl-D-aspartic acid (NMDA)-receptor mediated excitatory chemodrive inputs and a powerful inhibitory gain modulatory mechanism mediated via gamma-aminobutyric acidA (GABA(A)) receptors. We examined whether the depressant effect of halothane on expiratory neuronal activity is primarily caused by a reduction in glu...
