Tendon attaches to bone across a specialized tissue called the enthesis. This tissue modulates the transfer of muscle forces between two materials, i.e. tendon and bone, with vastly different mechanical properties. The enthesis for many tendons consists of a mineralized graded fibrocartilage that develops postnatally, concurrent with epiphyseal mineralization. Although it is well described that...
تداخل امواج رادیوئی تولید شده بواسطه چرخش پروانه ها در یک هلیکوپتر با سیستم رادار پالس دایلر تجزیه و تحلیل شده است . طیف توان امواج رادیوئی برگشتی از پروانه های هلیکوپتر برای سه سرعت و سه زاویه پائین نگری رادار در یک ارتفاع ثابت بدست آمده است . نتایج عددی نشان میدهد که علیرغم آنکه توان برگشتی از پروانه ها در ناحیه برگشت امواج رادیوئی از زمین حدود dbw/hz 10-5 کمتر از توان برگشتی از زمین است معهذ...
6. Suppose X is a metric space, let BX be the σ-algebra generated by the open sets of X, we call BX the Borel σ-algebra and its elements Borel sets. 7. A countable intersection of open sets is called a Gδ set ; a countable union of closed sets is called an Fσ set . 8. We call a collection of subsets of X an elementary family if (i) ∅ ∈ E ; (ii) if E,F ∈ E , then E ∩ F ∈ E ; and (iii) if E ∈ E ,...
The effect of rifampicin on the pharmacokinetics of fexofenadine enantiomers was examined in healthy subjects who received fexofenadine alone or with single or multiple doses of rifampicin (600 mg). A single coadministered dose of rifampicin significantly decreased the oral clearance (CLtot/F) and renal clearance (CLr) of Sand R-fexofenadine by 76 and 62%, and 73 and 62%, respectively. Even aft...
MicroRNA-206 (miR-206) has been discovered to have anticancer properties in different tissues. However, the role of miR-206 on renal carcinoma is still ambiguous. In the present study, we investigated the role of miR-206 on the development of renal carcinoma. The results indicated that miR-206 was significantly downregulated in 69 clear cell renal carcinoma (ccRCC) tissues and low-level of miR-...
PURPOSE MicroRNA-206 (miR-206) has been proven to be downregulated in many human malignancies and is correlated with tumor progression. However, the roles of miR-206 and its related molecular mechanisms in oral squamous cell carcinoma (OSCC) are still unclear. Thus, the aim of this study was to explore the effects of miR-206 in OSCC tumorigenesis and development. METHODS Quantitative real-tim...
microRNAs regulate the development of myogenic progenitors, and the formation of skeletal muscle fibers. However, the role miRNAs play in controlling the growth and adaptation of post-mitotic musculature is less clear. Here, we show that inhibition of the established pro-myogenic regulator miR-206 can promote hypertrophy and increased protein synthesis in post-mitotic cells of the myogenic line...
