“To assess etiology, perinatal mortality and associated factors of fetal cardiomegaly (FC).

A retrospective study of fetuses with cardiomegaly was conducted. Demographic data, ultrasonographic findings, and outcomes were collected and analyzed.


fetuses were analyzed. The causes of FC were cardiac causes 49.5%, Bart’s hemoglobinopathies 28%, and non-Bart’s anemia 15%. Ascites, pericardial effusion, and hydrops were more prevalent in fetuses with anemia than those with cardiac abnormalities. The overall perinatal mortality was 69.9%. selleck inhibitor Although all Bart’s hydrops died, perinatal mortality of non-Bart’s anemia, and structural cardiac defect were 57.1 and 69.7%, respectively. Excluding Bart’s anemia, receiver-operating characteristic curve analysis demonstrated that cardiothoracic ratio of a parts per thousand yen0.58 best predictive for perinatal mortality. Earlier gestational age at diagnosis, skin edema, and chromosomal abnormality were associated with higher mortality.

Majority causes of FC were cardiac and anemic in origin. It carried high-perinatal

mortality depending on the causes.”
“We present the spin momentum densities of CoFe(2)O(4) measured at 8 and 300 K using magnetic Compton scattering. The magnetic Compton profiles were decomposed into component profiles of constituents namely Fe and Co, to determine their role in the formation of total spin moment. It is seen GS-7977 clinical trial that the major contribution (about 80%) in the spin moment is from Co, whereas the itinerant electrons show a small reverse polarization. Moreover, it is clearly visualized that the

spin moment at Co reduces from 2.55 -> 2.35 mu B/f.u. while going from 8 -> 300 K. The magnetic Compton profiles, when compared with the magnetization JNK-IN-8 data, show about 17% contribution of orbital moment to the total magnetic moment at both temperatures. The origin of the orbital moment is explained on the basis of rotation of hole on t(2g) orbital of Co(+2) ion. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3650251]“
“A novel ester diamine, 9-(3,5-diaminobenzoyloxy) fluorene, as a new monomer for preparation of polyimides was synthesized via two successive reactions. In the first step, reaction of 3,5-dinitrobenzoylchloride with 9-hydroxy fluorene in the presence of sodium hydroxide led to preparation of 9-(3,5-dinitrobenzoyloxy) fluorene. Second reaction was reduction of the nitro groups by tin (II) chloride and fuming hydrochloric acid to produce 9-(3,5-diaminobenzoyloxy) fluorene. The new diamine containing bulky fluorene group was characterized and polycondensed with different dianhydrides via two methods to produce polyimides. The new five-membered and six-membered ring polyimides were characterized and their properties including solubility behavior, inherent viscosity, thermal behavior and stability, and crystallinity were studied.
