X-ray crystallography showed that the title compound, C(6)H(12)O(5), crystallizes in the α-pyran-ose form with the six-membered ring in a chair conformation. The crystal structure exists as a three-dimensional hydrogen-bonded network of mol-ecules with each mol-ecule acting as a donor and aceptor for four hydrogen bonds. The absolute configuration was determined by the use of l-fucose as starti...

Background: Ectopic pregnancy (EP) is a common condition which presents a major health problem for women of childbearing age. This study aims to analyze and identify risk factors that have the potential for EP and evaluating the contribution of the risk factors associated EP. Materials and Methods: In this case control study, performed from 2006 to 2011 at Arash hospital, the casepatients were ...

ectopic pregnancy (ep) and miscarriage are important differential diagnosis of first trimester vaginal bleeding. in first trimester, serum progesterone value can be 5-20 ng/ml in ep and miscarriage. since delay in diagnosis of ep could have high mortality and morbidity, the aim of this study was comparison of serum progesterone value in ep and miscarriage in order to differentiate these conditi...

background: ectopic pregnancy (ep) is a prevalent problem and the most common cause of maternal mortality at the first trimester. results from different studies are not consistent regarding the risk factors associated with ep. the current study aimed to investigate about risk factors associated with ep in kermanshah-iran. methods: a case–control study conducted to compare risk factors of ep amo...

We consider the pulsar velocity problem and relate it to some unconven-tional neutrino oscillation mechanisms based on a violation of the equivalence principle by neutrinos. We show that the observed pulsar velocities may be explained by violations at the level from 10 −9 to 10 −10 in the case of a non-universal tensor neutrino-gravity coupling, whereas there is no solution in the case of a non...

In the present study, we aimed to address the use of ethyl pyruvate (EP) against the harmful effects of cyclophosphamide (CP) treatment. Thirty-nine adult male mice were divided into three groups including control group received normal saline [0.20 mL per day; intraperitoneally (IP)], CP group received CP (15.00 mg kg-1 per week, IP) and CP+EP group received EP (40.00 mg kg-1</s...
