In this paper we wish to present a new class of tight frames on the sphere. These frames have excellent pointwise localization and approximation properties. These properties are based on pointwise localization of kernels arising in the spectral calculus for certain self-adjoint operators, and on a positive-weight quadrature formula for the sphere that the authors have recently developed. Improv...

Surgical treatment is effective to exclude all infected tissue in patients with infective endocarditis. Although various techniques have been reported, it has remained a great challenge for patients with extensive infected regions. A patient with extensive bivalvular endocarditis including the aortic and mitral valve and aorto-mitral continuity is described. A handmade aorto-mitral bioprostheti...

BACKGROUND The authors present a woman suffering from McKittrick-Wheelock syndrome (MKWS) with a giant rectal villous adenoma. MKWS is a rare disorder caused by fluid and electrolyte hypersecretion from a rectal tumor. The most frequently reported tumors are villous adenomas. Symptoms of dehydration with severe hyponatremia, hypokalemia, metabolic acidosis and acute renal failure are typical in...

INTRODUCTION There is an increasing use of enteral therapy at home, which reduces costs and improves patients' quality of life. Homemade food diets are being commonly used in the households of undeveloped countries, but those diets vary in composition and characteristics depending on the ingredients and preparation procedures adopted in its preparation, which influences the quality of the diet ...

Technology of somatic cell nuclear transfer (SCNT) has been adapted worldwide to generate transgenic animals, although the traditional procedure relies largely on instrumental micromanipulation. In this study, we used the modified handmade cloning (HMC) established in cattle and pig to produce transgenic sheep with elevated levels of omega-3 (n-3) fatty acids. Codon-optimized nematode mfat-1 wa...

Background: In several disease conditions, patients must inevitably be nourished by enteral feeding (EF). Though in many countries, commercial formulas are routinely used for EF, in Iran still home-made formulas are commonly employed as commercial formulas are not covered by insurance. This may pose patients to malnutrition and bring about further costs.  The aim of this study was to evalu...
