the distinction between malignant and benign pheochromocytoma has always been a diagnostic challenge over the last decades. to date, the only reliable criterion is metastasis. the aim of the present study was to investigate the possible expression of pituitary-tumor transforming gene (pttg1) and retinoblastoma (rb) in benign and malignant pheochromocytoma. paraffin blocks of 44 and 11 patients ...
The European species of the genera Amblyscelio and Baryconus are reviewed and revised based on morphological data. Females of Amblyscelio striaticeps Kieffer, 1913 and Baryconus graeffei (Kieffer, 1908) are described and the ovipositor of Amblyscelio is illustrated for the first time. The monotypic genus Amblyscelio was previously known only from a single male specimen. Baryconus graeffei is co...
leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. leptin and itsreceptor (ob-r) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. the goal of this study was determination of the presence of leptin receptor mrna in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...
background: the role of retinoblastoma (rb) protein in cell cycle regulation prompted us to take up this study with the aim of assessing its role in the progression of oral cancer and to correlate with various clinicopathological parameters, including habits such as smoking, paan chewing, and alcoholism. materials and methods: this observational study included surgical specimens from 10 apparen...
فضای سبز شهری در مناطق گوناگون جهان جزء ضروریات روزمره و جذابیت های محلی است. انتخاب گونه های مقاوم به خشکی برای کاشت در فضای سبز شهری در مناطق خشک و نیمه خشک به منظور ایجاد تنوع امری ضروری است. یکی از آزمایش های مهم سازگاری، به منظور معرفی گیاهان در مناطق جدید، بررسی ظهورشناسی گونه هاست. هدف اصلی این تحقیق شناسایی خصیصه های ظهورشناسی گونۀ بلوط به دو روش توصیفی و با استفاده از سری زمانی عکس برد...
chicken chemokine can help heal wounds by inducing fibroblasts to become myofibroblasts, according to results reported by Feugate et al. on page 161. The contractile myofibroblasts help close the wound by pulling together the necessary cells and matrix. Chemokines are better known for their activities in the immune system, but increased production of chicken chemotactic and angiogenic factor (c...
A prior retrospective study suggested that the level of retinoblastoma protein (RB) expression was prognostic for survival in acute myelogenous leukemia (AML). Individuals with no/low RB protein expression were considered to have loss of RB function, and those with maximally phosphorylated (maxphos) RB were also felt to have nonfunctional RB. To confirm this, we prospectively investigated wheth...
