While studying the neural precursor cell intermediate filament protein known as nestin in the developing mouse brain, we observed a strong cross-reaction of our nestin antibody with a 50 kDa protein that appeared on embryonic day 10 and continued to accumulate until postnatal day 1. Here we report evidence that this protein is a brain-specific variant form(More)
BACKGROUND Knowledge of predominant microbial patterns in community-acquired pneumonia (CAP) constitutes the basis for initial decisions about empirical antimicrobial treatment, so a prospective study was performed during 2003-2004 among CAP of adult Chinese urban populations. METHODS Qualified patients were enrolled and screened for bacterial, atypical,(More)
Studying seed dormancy and its consequent effect can provide important information for vegetation restoration and management. The present study investigated seed dormancy, seedling emergence and seed survival in the soil seed bank of Stipa bungeana, a grass species used in restoration of degraded land on the Loess Plateau in northwest China. Dormancy of(More)
In this paper, a new model is designed for welding flexible manufacturing system (WFMS) of multiple robots in a different way with Petri net (PN), which is multi-robot WFMS time Petri net (MRWTPN). Because the complexity of information and the device of welding system, the function of inhibit arc is imported in the model and we design two-layer way in(More)
We present four cases of cerebral cavernous angioma that developed after radiatherapy for brain tumor in three cases and for cavernous angioma in one case. The time interval between irradiation and the detection of the cavernous angioma varied from three to nine years and the doses from 24 to 60 Grays. Brain hemorrhage appeared in two cases. Explanation for(More)
We found T-type calcium channel blocker Ni2+ can efficiently induce the formation of cement gland in Xenopus laevis animal cap explants. Another T-type specific calcium channel blocker Amiloride can also induce the formation of cement gland, while L-type specific calcium channel blocker Nifedipine has no inductive effect. These results may offer us an new(More)
AVP and CRH produced in the parvocellular neurons of the paraventricular nucleus (PVN) have both been implicated in the regulation of anterior pituitary ACTH synthesis and secretion. In sheep, fetal ACTH secretion increases around 120 days gestational age (dGA). Little is known about adrenal regulation of AVP and CRH immediately prior to this critical(More)
In the ovine fetus, adrenalectomy at 90-120 days gestational age (dGA) results in a gradual increase in basal concentrations of fetal plasma ACTH beginning at approximately 122 dGA. Bilateral adrenalectomy at 116-119 dGA also results in an increase in POMC mRNA in the fetal pituitary. It is not known whether both the paraventricular nuclei (PVN) of the(More)
