منگنز-52 با نیمه عمر6/5 روز با واپاشی گیراندازی الکترون به میزان 63 % و با واپاشی پوزیترون به میزان 27 % به ایزوتوپ ناپایدار کروم-52 تبدیل می شود. این رادیوایزوتوپ به طور وسیعی در تحقیقات کشاورزی و فیزیولوژی و نیز گاهاً در پزشکی هسته ای مورد استفاده قرار می گیرد. در پروژه حاضر، امکان سنجی تولید رادیوایزوتوپ منگنز-52 توسط بمباران پروتونی هدف کروم طبیعی توسط شتابدهنده سیکلوترون با استفاده از کدها...

Bir sorun olarak erkek şiddetinin çözümüne ilişkin girişim ve tahayyüllerde kategorisi çoğunlukla sadece sorunla ilişkili ele alınır. Öte yandan bizzat erkeklerin kendisini de bu mücadelelerde pek görmez duymayız. Halbuki çözüme yönelik herhangi bir çaba sorunun sorumlu faillerinin dönüşümünden geçer bunun da ilk adımı çözümden ziyade sorunu tanımaktır. Bu sebeple, çalışmanın temel sorunsalını ...
Highly pathogenic H5N1 avian influenza viruses have caused major disease outbreaks in domestic and free-living birds with transmission to humans resulting in 59% mortality amongst 564 cases. The mutation of the amino acid at position 627 of the viral polymerase basic-2 protein (PB2) from glutamic acid (E) in avian isolates to lysine (K) in human isolates is frequently found, but it is not known...
BACKGROUND Endothelin (ET)-1 and norepinephrine (NE) are involved in myocardial ischemia/reperfusion injury. We investigated the role of ET-1 in ischemia/reperfusion-induced NE overflow and cardiac dysfunction using a selective ET(A) receptor antagonist (ABT-627), a selective ET(B) receptor antagonist (A-192621), and the spotting lethal (sl) rat, which carries a naturally occurring deletion in ...
PURPOSE The complement system has been implicated in the pathogenesis of age-related macular degeneration (AMD). Complement factor I (CFI) is a serum protease that inhibits all complement pathways. A previous multicenter study identified a single missense CFI mutation (p.Gly119Arg) in 20/3,567 (0.56%) of AMD cases versus 1/3,937 (0.025%) of controls, thus suggesting that this mutation confers a...
A 1500-m-thick Cenozoic sequence was recovered in a series of 3 drill holes from the Victoria Land Basin, Antarctica, in association with the Cape Roberts Project. The CRP-3 drill hole penetrated the oldest Palaeogene strata in the Granite Harbour region and terminated in strata from the Devonian Beacon Supergroup. The upper 823-m of the CRP-3 drill-core is an expanded sequence that may span th...
