background: the prevalence of setariasis in cattle and cerebrospinal nematodiasis in sheep and goats were determined in two geographical regions of iran. methods: in two provinces of iran: mazandaran (zone i) and qazvine (zoneii)   where sheep and goats were suffering from symptoms similar to cerebrospinal nematodiasis, the peritoneal cavities of  763 and 1020 cattle were searched for adult set...

Osteoclasts resorb bone through the formation of a unique attachment structure called the sealing zone. In this study, a role for thyroid hormone receptor-interacting protein 6 (TRIP6) in sealing zone formation and osteoclast activity was examined. TRIP6 was shown to reside in the sealing zone through its association with tropomyosin 4, an actin-binding protein that regulates sealing dimensions...

the gurpi formation, at the type section (nw of masjed-soleiman) and in sabze-kuh (sw of borujen) are lithologically subdivided into 8 and 11 units, respectively. the study of planktonic foraminifera resulted in recognition of 7 biozones in lali area and 4 biozones in sabzeh-kuh area. these biozones are compared to the most standard biozones defined in tethysian domain. biozones i (globotruncan...

The glycosphingolipid SSEA-4 and the glycoprotein YKL-40 have both been associated with human embryonic and neural stem cell differentiation. We investigated the distribution of SSEA-4 and YKL-40 positive cells in proliferative zones of human fetal forebrain using immunohistochemistry and double-labeling immunofluorescence. A few small rounded SSEA-4 and YKL-40 labeled cells were present in the...

BACKGROUND We conducted a systematic review to examine the efficacy of the Atkins, South Beach, Weight Watchers (WW), and Zone diets, with a particular focus on sustained weight loss at ≥12 months. METHODS AND RESULTS We systematically searched MEDLINE, EMBASE, and the Cochrane Library of Clinical Trials to identify randomized controlled trials (RCTs) published in English with follow-up ≥4 we...

in advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. the gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (edz) above the gate roadway and 2) loading effect due to the caving zone (cz) above the longwall w...

PURPOSE We determine whether biochemical prostate specific antigen (PSA) failure can be accurately predicted from preoperative serum PSA combined with 6 morphological variables from radical retropubic prostatectomy specimens in men with peripheral zone cancers. The unexpected limitation imposed by preoperative serum PSA on biochemical failure led us to compare peripheral zone to transition zone...

The mammalian rod synapse transmits a binary signal (one photon or none) using tonic, rapid exocytosis. We constructed a quantitative, physical model of the synapse. Presynaptically, a single, linear active zone provides docking sites for approximately 130 vesicles, and a "ribbon" anchored to the active zone provides a depot for approximately 640 vesicles. Postsynaptically, 4 processes invagina...

corresponded to ethyl-3-indoleacetate (Rf 0.81) and 3-indoleacetonitrile (Rf 0.76). However, the zone neither developed typical colors with Salkowski and Ehrlich spray reagents nor possessed an ultraviolet absorption spectrum typical of the indole moiety (see above). The eluate from the growth stimulating zone of Rf 0.00 to 0.16 in figure 4 had an ultraviolet absorption spectrum identical with ...
