An epidemiological cross-sectional study was undertaken to determine the endemicity of malaria among the Orang Asli population of Raub, Pahang. Malaria endemicity was measured in terms of the prevalence of parasitaemia and splenomegaly. A total of 520 Orang Asli were examined. The point prevalence of malaria was 24.2% (95% CI 20.7-25.1), with Plasmodium falciparum (67.5%) being the predominant ...

6,6′-(Pyridine-2,6-di­yl)bis­(pyrrolo­[3,4-b]pyridine-5,7-dione)

The title compound, C(19)H(9)N(5)O(4), has crystallographically imposed twofold rotational symmetry. The asymmetric unit contains one half-mol-ecule. The crystal structure is stabilized by π-π stacking of inversion-related pyrrolo-[3,4-b]pyridine rings, with a centroid-centroid distance between stacked pyridines of 3.6960 (8) Å. The dihedral angle between the central pyridine ring and the pyrro...

طراحی و سنتز مشتقات جدید 1h-pyrrolo [3, 4-c] pyridine-1, 3(2h)-dione

مقدمه: صرع سندرم اختلالات مغزی مختلف سیستم اعصاب مرکزی است که 1-5/. درصد جمعیت جهان را تحت تاثیر قرار داده است. حدود 25 درصد از این بیماران به درمان های دارویی موجود مقاومند. علاوه بر این داروهای ضدتشنجی که امروزه مورد مصرف قرار می گیرند، رنج وسیعی از عوارض جانبی را نشان می دهند. بنابراین در حال حاضر نیاز به ایجاد ترکیبات جدید با حداکثر فعالیت ضدتشنجی و حداقل عوارض جانبی و سمیت عصبی احساس می شو...

Structure and Magnetic Properties of Sm ( CobalFexTi 0 : 05 ) 9 : 66 Alloys ( x = 0 - 0 . 57 ) and Sm ( Co 0 : 66 Fe 0 : 19

Potential permanent magnetic materials with compositions of Sm(CobalFe Ti0 05)9 66 ( = 0–0.57) have been synthesized and characterized in the temperature range of 10–1473 K and at fields up to 5 T. The experimental results show that near single phase materials with Th2Ni17 structure were formed in Sm(CobalFe Ti0 05)9 66 alloys after splat quenching from 1473 K. The Ti atoms play an important ro...
