The majority of posterior inferior cerebellar artery (PICA) aneurysms are usually found on the bifurcation of the vertebral artery (VA) - PICA junction. Aneurysms arising from more peripheral PICA segments named distal PICA aneurysm are uncommon. The major clinical manifestation is that of an intracranial bleeding and the site of hemorrhage is related to the PICA segment originating the aneurys...

Among the variations of vertebral artery dissecting aneurysms (VDAs), VDAs involving the posterior inferior cerebellar artery (PICA), especially ruptured and high-risk unruptured aneurysms, are the most difficult to treat. Because the PICA is an important structure, serious symptoms may occur after its occlusion. Retained PICAs are prone to re-bleeding because VDAs are difficult to completely o...

OBJECTIVE To describe pica behavior (ingestion of nonfood items) in pregnant low-income Mexican-born women in Mexico and the United States. DESIGN A convenience sample of informants was interviewed with a questionnaire containing open-ended and closed-ended questions. SETTING A low-income community on the outskirts of Ensenada, Mexico, and clinics serving low-income people in southern Calif...

ourmia melon virus (oumv) is the causal agent of mosaic disease on melon in west-azerbaijan province and probably in some other parts of iran. symptomatic and non-symptomatic samples of cultivated and non-cultivated hosts were collected from most cucurbit-planting parts of the province and surveyed using common serological methods namely: indirect-elisa, direct-elisa and lateral flow. some squa...

BACKGROUND AND PURPOSE The rate of PICA occlusion after flow-diverting stent placement for vertebral and vertebrobasilar artery aneurysms is not known. The purpose of this study is to determine the medium-term rate of PICA patency and risk factors for occlusion after such aneurysm treatment. MATERIALS AND METHODS Patients were identified who had vertebral or vertebrobasilar artery aneurysms a...

in order to study the effect of soil nitrogen content and water hardness on glyphosate efficacy on common lambsquarter (chenopodium album l.) and redroot pigweed (amaranthus retroflexus l.) control, an experiment was carried out as a completely randomized design in a factorial arrangement with three replications. experimental treatments were included soil nitrogen content (18, 50, 90, 200 and 3...

The present study was conducted to assess the risk to human health by microbial load and heavy metals (Cr, Cu, Ni, Zn, Cd and Pb) through the intake of locally grown vegetables irrigated by metal contaminated water and waste water in Delhi and NCR region. Twenty-two varieties of vegetables grown in the agricultural land were collected for analysis. The results revealed that concentrations of co...

Scirtidae described by J. Ch. Fabricius are listed. Poorly known South American and Indian species are redescribed, illustrated and figured. Cyphon depressus Fabricius is transferred to Ora Clark, and Cistela livida Fabricius is transferred to Pseudomicrocara Armstrong. Ora complanata (Guerin-Meneville) is probably a junior synonym of Ora depressa (Fabricius). Data on Scirtidae collections stud...

A total of 231 different soil Streptomyces isolates were recovered from 16 different locations in North Jordan. They were assessed for their phytotoxic activity on seeds of cucumber (Cucumis sativus L.) and ryegrass (Lolium perenne L.) placed adjacent to a 2 cm wide Streptomyces culture strips grown at 28C degrees for 3 weeks on starch casein nitrate (SCN) agar. Phytotoxicity was ascertained on...
