The Persian sturgeon (Acipenser persicus) is considered as an endemic sturgeon of the south part of the Caspian Sea and provides the highest Iranian caviar production. Due to overfishing, degradation of the rivers conditions of the natural reproductive habitats, the fish stocks is decreasing. The immature breeders do not response to hormonal therapy at the sturgeon hatcheries as most having PI...
The attachment of a sugar to a hydrophobic polyisoprenyl carrier is the first step for all extracellular glycosylation processes. The enzymes that perform these reactions, polyisoprenyl-glycosyltransferases (PI-GTs) include dolichol phosphate mannose synthase (DPMS), which generates the mannose donor for glycosylation in the endoplasmic reticulum. Here we report the 3.0 Å resolution crystal str...
In the present study, post inflammation irritable bowel syndrome (PI-IBS) rats were firstly established by intracolonic instillation of acetic acid with restraint stress. Then the pharmacokinetics of berberine in the rat plasma were compared after oral administration of berberine hydrochloride (25 mg/kg) to normal rats and PI-IBS rats. Quantification of berberine in the rat plasma was achieved ...
A precision measurement of the mass of the h_{c}(1P1) state of charmonium has been made using a sample of 24.5x10;{6} psi(2S) events produced in e;{+}e;{-} annihilation at the Cornell Electron Storage Ring (CESR). The reaction used was psi(2S)-->pi;{0}h_{c}, pi;{0}-->gammagamma, h_{c}-->gammaeta_{c}, and the reaction products were detected in the CLEO-c detector. Data have been analyzed both fo...
In this paper, we continue the investigation proposed in [15] about the approximability of Pk partition problems, but focusing here on their complexity. More precisely, we prove that the problem consisting of deciding if a graph of nk vertices has n vertex disjoint simple paths {P1, · · · , Pn} such that each path Pi has k vertices is NP-complete, even in bipartite graphs of maximum degree 3. N...
Given a set S of points in the plane, the k-Gabriel graph of S is the geometric graph with vertex set S, where pi, pj ∈ S are connected by an edge if and only if the closed disk having segment pipj as diameter contains at most k points of S \ {pi, pj}. We consider the following question: What is the minimum value of k such that the k-Gabriel graph of every point set S contains a Hamiltonian cyc...
An agonist-occupied beta(2)-adrenergic receptor (beta(2)-AR) recruits G protein receptor kinase-2 (GRK2) which is recruited to the membrane. Thus, the physical proximity of activated beta(2)-AR and PI-3K allows the activation of the latter. In contrast, it has been observed that the beta(1)-AR is unable to activate the PI-3K/Akt pathway. We hypothesized that the difference might be due to molec...
We welcome the cross-sectional, observational, case-finding study on alpha-1 antitrypsin deficiency (AATD) in 1002 individuals with COPD conducted by Sorroche et al. in Buenos Aires. This is the first study of its kind in Argentina.1 The authors set out to identify all genotypes associated with severe AATD (namely, Pi*ZZ and Pi*SZ) using an effective screening technique based on the quantificat...
The viability of Giardia muris cysts was studied with the fluorogenic dyes fluorescein diacetate (FDA) and propidium iodide (PI). G. muris cysts were seen to fluoresce intensely green with FDA at an excitation wavelength of 450 to 490 nm. Cysts stained with PI fluoresced bright orange at an excitation wavelength of 450 to 490 nm and bright red at 545 to 546 nm. Examination of isolated G. muris ...
Rationale The objective of these studies was to assess the impact of the Jeffrey Modell Foundation's Physician Education and Public Awareness Campaign (PEPAC) on early diagnosis and management of Primary Immunodeficiencies (PI), and to make available an overview of the data provided by physician experts from the Jeffrey Modell Centers Network (JMCN) of Diagnostic, Research, and Referral Centers...
