BACKGROUND Incidence of spontaneous subarachnoid hemorrhages (SAH) varies wildly across the world and seems to be low in Central and South America (4.2 per 100 000 person-years; CI 95%; 3.1-5.7). The objective of our study was to describe the characteristics of SAH and to estimate its incidence and severity in Martinique, a small French island located in the Caribbean Sea. METHODS Due to its ...

Some gastropod specimens belonging to the planorbid genus Ferrissia were recently collected in Lebanon and in Iraq, where the autochthonous species Ferrissia clessiniana (Jickeli, 1882) is supposed to occur. The molecular identification of collected specimens proved that they belong to the allochthonous species Ferrissia fragilis (Tryon, 1863), the protagonist of a dramatic cryptic invasion whi...

The bacterial mutagenicity of a set of 1993 urban particulate air pollution samples is examined using the Salmonella typhimurium TM677 forward mutation assay. Amibent fine particulate samples were collected for 24 hr every sixth day throughout 1993 at four urban sites, including Long Beach, central Los Angeles, Azusa, and Rubidoux, California, and at an upwind background site on San Nicolas Isl...

This study was performed in order to determine the distance of isolation for the seed potato production from ware potato in three regions of Ardabil, Namin and Nir. The experiment was carried out in a randomized complete block design (RCBD) with five distances (100, 200, 300, 400 and 500 meters from ware potato) and three replications with Super Elite (SE) class of Agria potato cultivar from wa...

A procedure is described for the isolation of native DNA from protoplasts of ammi (Ammi visnaga) and carrot (Daucus carota) cells. Protoplasts were produced from 40 grams of fresh cells by enzyme hydrolysis and lysed with sodium dodecyl sulfate. The DNA was purified by treatment with pronase and ribonuclease. Final isolation was achieved by sucrose density gradient centrifugation.The melting te...

wind speed is one of the characteristics of wind energy which its data is extracted from meteorological stations. in this study, the data obtained from the weather station in the city eqlid during a ten-year period has been used. weibull distribution was chosen as the best distribution function using fitting tests and estimation of some statistical parameters. the results showed that the averag...

the fixed regression test-day model (frm) and random regression test-day model (rrm) for genetic evaluation of milk yield trait of dairy cattle in khorasan razavi province were studied. breeding values and genetic parameters of milk yield trait from two models were compared. a total of 164391 monthly test day milk records (three times milking per day) obtained from 19217 holstein cows distribut...

BACKGROUND Trends in cardiovascular mortality across Europe demonstrate significant geographical variation, and an understanding of these trends has a central role in global public health. METHODS AND RESULTS Ischemic heart disease and cerebrovascular disease age-standardized death rates (as per International Classification of Diseases, ninth and tenth revisions) were collated from the World ...

Informative parameters for statistical estimation of operational error SAMGAS, METRIX, PREMAGAS household gas meters (HGM) are formulated. These the values measured volume during verification period operation and experimentally determined meter at three normalized flow rates: minimum, maximum 20% maximum.
 Six ranges variation HGM minimum rate were selected to form samples meters. Accordin...

Methods: A prospective randomized-controlled trial was conducted on 200 patients with ectopic pregnancy at the Obstetrics and gynecological Departments of Zagazig University, Egypt between June, 20 11 to May 2014. Patients were randomized into two groups, (group 1) who received a single dose 50 mg per meters squared surface area methotrexate (50 mg/m2 IM on day 1) intramuscularly or (group 2), ...
