Objective(s): To investigate the protective effect of glycyrrhizin (GL) on hepatic ischemia-reperfusion injury (HIRI).Materials and Methods: Forty SD rats were randomly divided into sham group, HIRI group, GL 100 mg/kg group, and GL 200 mg/kg group. The pathological alterations of liver tissue in each group were observed. The levels of a...
In this paper, a new numerical scheme for the time dependent GinzburgLandau (GL) equations under the Lorentz gauge is proposed. We first rewrite the original GL equations into a new mixed formulation, which consists of three parabolic equations for the order parameter ψ, the magnetic field σ= curlA, the electric potential θ=divA and a vector ordinary differential equation for the magnetic poten...
Two eyestalk (ES) neuropeptides, molt-inhibiting hormone (MIH) and crustacean hyperglycemic hormone (CHH), increase intracellular cGMP levels in target tissues. Both MIH and CHH inhibit ecdysteroid secretion by the molting gland or Y-organ (YO), but apparently through different guanylyl cyclase (GC)-dependent pathways. MIH signaling may be mediated by nitric oxide synthase (NOS) and NO-sensitiv...
In vitro regeneration of four cultivars of carnation namely ‘Nelson’, ‘Impulse’, ‘Sagres’ and ‘Spitit’ through somatic embryogenesis was studied. MS culture medium was supplemented with 30 gl-1 sucrose, 2 mgl-1 2,4-D and 0.2 mgl-1 BA and used for embryogenic callus formation. Somatic embryos were formed when embryogenic callus was transferred to MS medium without growth regulators containing 30...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
XMM-Newton and Chandra observations of the transient 7.8 s pulsar XTE J1829−098 are used to characterize its pulse shape and spectrum, and to facilitate a search for an optical or infrared counterpart. In outburst, the absorbed, hard X-ray spectrum with Γ = 0.76 ± 0.13 and NH = (6.0 ± 0.6) × 10 22 cm is typical of X-ray binary pulsars. The precise Chandra localization in a faint state leads to ...

background: there is no clear data on the adherence of emergency medical services (ems) paramedics and hospital staff rather than those working in poisoning centers to the guidelines for managing acutely poisoned patients in developing countries. methods: during a 6-month period, all ems-managed poisoned patients along with those initially managed in a non-poisoning center before being referred...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
The development of ovarian follicles and subsequent corpus luteum formation is accompanied by very active angiogenesis. Ovarian granulosa cells produce vascular endothelial growth factor (VEGF), which is a potent endothelial cell mitogen and an angiogenic agent. The complementary DNAs of two other factors structurally related to VEGF, namely VEGF-B and VEGF-C, were recently cloned, but little i...
