Purpose: This study was designed to evaluate the diagnostic value of digital Bitewing (BW) radiographs with and without horizontal tube shift in detecting Residual excess cement (REC) on proximal non-proximal surfaces implant restorations. Material Methods: Eight mandibular models were fabricated two implants placed each side premolar first molar positions. Excess applied either or restorations...

The research was aimed at referring to contemporary problems concerning fractures of the proximal femur that, particularly in older patients, represent not only medical, but also social and nursing difficulties. Within November 2004 to March 2006, 83 patients with proximal femoral fractures were treated using PFN. Except for two cases, the post-operative course was favourable and patients could...

The lung is a branched tubular network with two distinct compartments--the proximal conducting airways and the peripheral gas exchange region--separated by a discrete boundary termed the bronchoalveolar duct junction (BADJ). Here we image the developing mouse lung in three-dimensions (3D) and show that two nested developmental waves demarcate the BADJ under the control of a global hormonal sign...

we introduce a new concept of general $g$-$eta$-monotone operator generalizing the general $(h,eta)$-monotone operator cite{arvar2, arvar1}, general $h-$ monotone operator cite{xiahuang} in banach spaces, and also generalizing $g$-$eta$-monotone operator cite{zhang}, $(a, eta)$-monotone operator cite{verma2}, $a$-monotone operator cite{verma0}, $(h, eta)$-monotone operator cite{fanghuang}...

background: osteoporosis is a chronic disease that contributes substantially to decrease physical activity and decline in the quality of life. osteoporosis can be diagnosed easily with the use of dual-energy x-ray absorptiometry (dxa) equipment. the aim of this study was to investigate the magnitude of bone loss on proximal femur and lumbar spine ls in pre- and post-menopausal women from isfaha...

introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...

Ischemia causes desquamation of proximal tubular epithelial cells leading to acute renal failure. However, the molecular mechanisms underlying the detachment of proximal tubule cells remain unknown. In this study, we reported that ATP depletion resulted in actin polymerization, a shift of filamentous actin from web-like structure to fragmented parallel stress fibers, followed by a reduction of ...

A proxy rainfall record for northeastern South Africa based on carbon isotope analysis of four baobab (Adansonia digitata L.) trees shows centennial and decadal scale variability over the last 1,000 years. The record is in good agreement with a 200-year tree ring record from Zimbabwe, and it indicates the existence of a rainfall dipole between the summer and winter rainfall areas of South Afric...
