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...

A standard class of finite dimensional control systems is considered, along with a state constraint set S and a target set Σ ⊂ S. Under certain geometric assumptions on S and a required S-constrained small time controllability property, a proximal Hamilton-Jacobi characterization of the S-constrained minimal time function to target Σ is obtained.

We consider variational inequality problems for set-valued vector fields on general Riemannian manifolds. The existence results of the solution, convexity of the solution set, and the convergence property of the proximal point algorithm for the variational inequality problems for set-valued mappings on Riemannian manifolds are established. Applications to convex optimization problems on Riemann...

Recently, sparse coding has been widely used in many applications ranging from image recovery to pattern recognition. The low mutual coherence of a dictionary is an important property that ensures the optimality of the sparse code generated from this dictionary. Indeed, most existing dictionary learning methods for sparse coding either implicitly or explicitly tried to learn an incoherent dicti...

We investigated the subcellular sites of glycoprotein oligosaccharide maturation by using lectin conjugates to stain lightly-fixed, saponin-permeabilized myeloma cells. At the electron microscopic level, concanavalin A-peroxidase stains the cisternal space of the nuclear envelope, the rough endoplasmic reticulum, and cisternae along the proximal face of the Golgi stack. Conversely, wheat germ a...

Primary culture of proximal tubule cells have provided useful model for the study of proximal tubule cell function, especially transport studies. Kidney is excised from the anesthetized rat, cortex is separated and proximal tubule cells are isolated by using DNAse-collagenase and separated by using different mesh size sieves and collagen coated surfaces of flasks containing 15% Dulbecco’s Modif...

BACKGROUND Proximal stomach by virtue of its property of accommodation acts as a reservoir for the ingested food, but its role in emptying and the factors modulating it remain unexplored. AIM To assess the effects of distension and of feeding on proximal gastric tone. SUBJECTS 14 healthy volunteers with no current or past history of any gastro-intestinal symptoms. METHODS Isobaric changes...

In this paper, we first present several characterizations for the weak sharpness of solution set variational inequality problems on Hadamard manifolds. Some these results answer an open question raised in [L. V. Nguyen, Optimization, 70 (2021) 1443-1458]. We then establish some abstract finite termination property sequences generated by iterative methods under or linear conditioning sets. Final...
