Objective(s): The current study was conducted to examine the possible protective and retentive effects of one-week intra-peritoneal (IP) administration of selenium nanoparticles (Se-NPs), compared to its bulk counterpart, selenite sodium (Ss), after one complete cycle of spermatogenesis in mature male mice. Materials and Methods: Thirty adult male mice were divided into 3 groups. Control group ...

The main objective of this research investigational studies is to formulate floating matrix tablets glimipride by applying simplex centroid design for optimization technique and direct compression method. Centroid configuration was drilled as an enhancement strategy adjusting the amount three components all while holding back their total concentration constant. Ingredients HPMC K15m, Kappa-carr...

Although dual-mobility sockets have been in clinical use for decades in other parts of the world, they recently gained popularity in the United States as an option for primary and revision total hip arthroplasty (THA). Improvements in dual-mobility socket technology include articulation with a metal insert impacted into a metal shell and a femoral head made of highly cross-linked polyethylene. ...

We present the results of 525 primary Souter elbow arthroplasties undertaken in 406 patients between 1982 and 1997. There were 372 women and 34 men with a mean age of 57 years; 119 patients had a bilateral procedure. The elbows were affected by chronic inflammatory disease, usually rheumatoid arthritis, which had been present for a mean of 24.7 years (2 to 70). In about 30% the joints were gros...

A tournament T is a pair (A,≻), whereA is a set of alternatives and ≻ is an asymmetric and complete (and thus irreflexive) binary relation on A, usually referred to as the dominance relation. The dominance relation can be extended to sets of alternatives by writing X ≻ Y when x ≻ y for all x ∈ X and y ∈ Y . For a tournament (A,≻), an alternative x ∈ A, and a subset X ⊆ A of alternatives, we den...

The purpose of this study is to evaluate the in vitro and in vivo performance of gastro-retentive matrix tablets having Metformin HCl as model drug and combination of natural polymers. A total of 16 formulations were prepared by a wet granulation method using xanthan, tamarind seed powder, tamarind kernel powder and salep as the gel-forming agents and sodium bicarbonate as a gas-forming agent. ...

chronic subdural hematoma (csdh) is a curable entity frequently encountered by neurosurgeons. the present study was conducted to explore expert opinion and common practice in iran. besides, a review of randomized clinical trials in literature was performed. a questionnaire including six questions discussing major aspects of practice on csdh, with multiple choices was designed. a pilot study was...

in this paper, we calculate electron and hole impactionization coefficients in in0.52al0.48as using a monte carlo modelwhich has two valleys and two bands for electrons and holesrespectively. also, we calculate multiplication factor for electronand hole initiated multiplication regimes and breakdown voltagein in0.52al0.48as pin avalanche photodiodes. to validate themodel, we compare our simulat...
