BACKGROUND AND PURPOSE Previous authors have described the locations of provoked responses to cervical diskography from C3-C4 to C6-C7, but we have found no description of the findings at C2-C3. This study was undertaken to analyze the sensations provoked during cervical diskography at C2-C3 and to compare the results with those provoked at C3-C4 and C4-C5. METHODS The locations of diskograph...
Introduction. According to the National Cancer Institute (NCI) guidelines in 1996, breast lesions are categorized as C1 to C5 on fine needle aspiration (FNA) cytology. Very few studies are available in the English literature analyzing histopathology outcome of C3 (atypical, probably benign) and C4 (suspicious, probably malignant) lesions. Our study aims to correlate FNA cytology of breast lump ...
هدف از این پروژه مطالعه علت آنمی و ترمبوسیتوپنی در بیماری کالا آزار که یک مرض بومی و شایع در این منطقه است میباشد. بدین منظور بیماران مبتلا به کالا آزار از طریق علائم بالینی و همچنین روش های سرولوژی تشخیص داده شده و سپس وجود آنتی بادی و یا کمپلمان در سطح گلبول های قرمز این بیماران بوسیله آزمایش مستقیم آنتی گلبولین بررسی گردید. نتیجه آزمایشات نشان داد که گلبول های قرمز بیمارانیکه مورد مطالعه ما ...
The C4-photosynthetic carbon cycle is an elaborated addition to the classical C3-photosynthetic pathway, which improves solar conversion efficiency. The key enzyme in this pathway, phosphoenolpyruvate carboxylase, has evolved from an ancestral non-photosynthetic C3 phosphoenolpyruvate carboxylase. During evolution, C4 phosphoenolpyruvate carboxylase has increased its kinetic efficiency and redu...
چکیده ندارد.
The C4 photosynthetic pathway uses water more efficiently than the C3 type, yet biogeographical analyses show a decline in C4 species relative to C3 species with decreasing rainfall. To investigate this paradox, the hypothesis that the C4 advantage over C3 photosynthesis is diminished by drought was tested, and the underlying stomatal and metabolic mechanisms of this response determined. The ef...
