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 ...
We compared the structural, biochemical, and physiological characteristics involved in photorespiration of intergeneric hybrids differing in genome constitution (DtDtR, DtDtRR, and DtRR) between the C3-C4 intermediate species Diplotaxis tenuifolia (DtDt) and the C3 species radish (Raphanus sativus; RR). The bundle sheath (BS) cells in D. tenuifolia included many centripetally located chloroplas...
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...
مقدمه: با توجه بااینکه تکالیف هماهنگی دودستی امری روزمره و غالب است. این مطالعه با هدف بررسی تأثیر دست برتری و دشواری تکلیف هماهنگی دودستی بر امواج مغزی نواحی حرکتی اولیه و ناحیه حرکتی مکمل (نقاط C3 و C4) بود. روش: پژوهش حاضر از نوع نیمه تجربی است؛ که در آن تعداد 10 زن راستدست و 10 زن چپدست با میانگین سنی 8/42 بهصورت هدفمند انتخاب شدند. تمامی شرکتکنندگان پنج تکلیف هماهنگی دودستی با دشواری ...
A well-known case of evolutionary adaptation is that of ribulose-1,5-bisphosphate carboxylase (RubisCO), the enzyme responsible for fixation of CO2 during photosynthesis. Although the majority of plants use the ancestral C3 photosynthetic pathway, many flowering plants have evolved a derived pathway named C4 photosynthesis. The latter concentrates CO2, and C4 RubisCOs consequently have lower sp...
