objective: pseudoexfoliation syndrome (pex) leads to some problems in the eye surgery specially cataract surgery. as the prevalence of eye problems is high in diabetic patients, we meant to assess the prevalence of pex in diabetic patients. materials and methods: in this cross-sectional study, 400 type 2 diabetic patients aged 50 or above who referred to yazd diabetes research center were selec...

obesity is one of the health problems in the developing and developed countries. obesity subjects the individuals with metabolic and endocrine disorders. it is obvious that vitamin d deficiency or insufficiency may lead to secondary hyperparathyroidism. thus, obesity increases the risk of vitamin d deficiency. considering the high prevalence of vitamin d deficiency in children and adolescents w...

sjogren syndrome (ss) can occur alone, primary sjogren syndrome, or in association with other rheumatic diseases, secondary sjogren syndrome (sss), such as rheumatoid arthritis (ra). the occurrence of sjogren syndrome with ra makes it course worse and increases high morbidity and mortality of ra. in this exploratory study we aim to determine the prevalence of sss (diagnosed based on the revised...

the present study introduces a rare case with secondary glaucoma due to anterior chamber lipoma and uveitis in a pekingese dog in iran. a four-year-old castrated male pekingese dog was referred to the private clinic with impaired vision of the left eye, pain, rubbing the left eye onto carpet, presence of a milkycoloured mass into the anterior chamber, and loss of appetite. the clinical examinat...

the automatic assignment of protein secondary structure from three dimensional coordinates is an essentialstep in the characterization of protein structure.although, the recognition of secondary structures suchas alpha-helices and beta-sheets seem straightforward, but there are many different definitions, eachregarding different criteria. we have developed a newalgorithm for protein helix assig...

‎In this work‎, ‎we introduce the concept of classical 2-absorbing secondary modules over a commutative ring as a generalization of secondary modules and investigate some basic properties of this class of modules‎. ‎Let $R$ be a commutative ring with‎ ‎identity‎. ‎We say that a non-zero submodule $N$ of an $R$-module $M$ is a‎ ‎emph{classical 2-absorbing secondary submodule} of $M$ ...

many investigators use bone matrix gelatin for bone induction but it is used rarely for repair of teeth defects. this study was designed to evaluate secondary dentin formation by endochondral bone matrix gelatin (e-bmg) in rabbit. e-bmg was prepared from tibia and femur of 4 deutsche-poland rabbits with average ages of 4-6 months. the prepared e-bmg was implanted in right incisor teeth pulps of...

to obtain an optimum formulation for stabilizers–emulsifier in ice cream, different combinations of three stabilizers, i.e. basil seed gum, guar gum, and carboxymethyl cellulose, at two concentrations of 0.15 or 0.35% with or without e471 emulsifier were studied using a simplex-centroid mixture design. the regression models for physical properties and texture smoothness of samples were also est...

viroids are smallest, single-stranded, circular, highly structured plant pathogenic rnas that do not code for any protein. viroids belong to two families, the avsunviroidae and the pospiviroidae. members of the pospiviroidae family adopt a rod-like secondary structure. in this study the most stable secondary structures of citrus viroid variants that reported from fars province were drawn. the m...
