background and aim: total hip replacement (thr) is done comprehensively all over the world. despite the effects of braces on control of thr complications , few studies have been performed on this subject. the purpose of this study was to evaluate immediate effect of hip abduction brace on mobility and functional balance of patients with thr.    materials and methods: eight men and nine women wi...

payment mechanism health insurance is a serious challenge for policy makers, access to health, continuing care, need to technology, huge expenses a considerable part of health funds is collected. therefore organizing and designing appropriate policies for organizing, financing, payment mechanism for providers and role of diagnostic related groups system. in this study, our main objective study ...

multiple sclerosis (m.s) is one of the prevalent diseases of the central nervous system which cause disability in young adults. this appears as neural signs in different parts and various times. the main defect is local deterioration or destruction of myelin tissue in the brain and spinal cord. profound fatigue is one the most common symptoms of this disease. because ms is prevalent in middle a...

well faceted cuo nanoparticles, were synthesized by thermal-assisted dissociation method at reflux temperature in a short period of time. a possible mechanism for synthesis of such highly pure and stable nanoparticles is tentatively proposed by ft-ir study. the large surface area and rich exposed active sites are expected to endow such nanoparticles with excellent performances in catalysis as d...

introduction: radiation induced bystander effect (ribe) which cause radiation effects in non-irradiated cells, has challenged the principle according to which radiation traversal through the nucleus of a cell is necessary for producing biological responses. what is the mechanism of this phenomenon? to have a better understanding of this rather ambiguous concept substantial number of original an...

Evidence has been presented for a metabolic multienzyme complex, the purinosome, that participates in de novo purine biosynthesis to form clusters in the cytoplasm of living cells under purine-depleted conditions. Here we identified, using fluorescent live cell imaging, that a microtubule network appears to physically control the spatial distribution of purinosomes in the cytoplasm. Application...

Pyrabactin is a synthetic abscisic acid (ABA) agonist that selectively inhibits seed germination. The use of pyrabactin was pivotal in the identification of the PYR1/PYL/RCAR family (PYL) of proteins as the ABA receptor. Although they both act through PYL proteins, pyrabactin and ABA share no apparent chemical or structural similarity. It remains unclear how pyrabactin functions as an ABA agoni...

This study addresses four questions in vertebrate functional morphology through a study of aquatic prey capture in ambystomatid salamanders: How does the feeding mechanism of aquatic salamanders function as a biomechanical system? How similar are the biomechanics of suction feeding in aquatic salamanders and ray-finned fishes? What quantitative relationship does information extracted from elect...

Antibiogram profile of 1590 clinical bacterial isolates based on thirteen different antimicrobial compounds showed that 1.6% of the bacterial isolates are multidrug resistant. Distribution pattern based on 16S rRNA sequence analysis showed that Pseudomonas aeruginosa constituted the largest group (83.6%) followed by Burkholderia pseudomallei sp. A191 (5.17%), Staphylococcus sp. A261 (3.45%). Am...

We sketch a framework for building a unified science of cognition. This unification is achieved by showing how functional analyses of cognitive capacities can be integrated with the multilevel mechanistic explanations of neural systems. The core idea is that functional analyses are sketches of mechanisms, in which some structural aspects of a mechanistic explanation are omitted. Once the missin...
