Objective(s): In this study, a stable bear bile-loaded pH sensitive in-situ eye drop gel was prepared for sustain delivery and enhanced therapeutic application. Materials and Methods: Bear bile-loaded in-situ ocular gels with different Carbopol/Hydroxypropyl methylcellulose (HPMC)  ratios were prepared and their stability was tested in P...

background: exercise and rehabilitation are important methods for decreasing the risk factors of coronary artery disease (cad). we aimed to evaluate the effect of the cardiac rehabilitation (cr) exercise program on the cardiac structure and physiology in patients undergoing percutaneous coronary intervention (pci). methods: in this randomized controlled study, 146 patients with cad were divided...

a variety of nervous system components such as medulla, pons, midbrain, cerebellum, basal ganglia, parietal, frontal and occipital lobes have role in eye movement desensitization and reprocessing (emdr) processes. the eye movement is done simultaneously for attracting client's attention to an external stimulus while concentrating on a certain internal subject. eye movement guided by therap...

sound power is considered as an excellent measure for evaluating the efficiency of noise controls as well as for comparing noise sources in workrooms. this parameter can be determined by sound pressure or intensity based methods in real conditions of workrooms. this paper aims empirically to compare these in situ methods in relation to a typical industrial machine located in workroom in terms o...

in this work, a thermoplastic polyurethane elastomer (tpue) model based on polytetramethylene glycol, toluene diisocyanate and 1,4-butanediol was selected and synthesized. according to this model two types of polyurethane nanocomposites were prepared by in situ polymerization and melt intercalation procedures. the organo-modified nanoclay was used in nanocomposites samples in 0.4 weight percent...

bis(2-r-ind)zrcl2 (r: h or phenyl) was supported on different types of silica by in situ impregnation method and used for ethylene polymerization. in this method, the step of catalyst loading on support was eliminated and common alkyl aluminum (triisobutylaluminum, tiba) cocatalyst was used instead of expensive methyl aluminiumoxane (mao) cocatalyst in the polymerization. the effect of surface ...

in studying of the in situ gravitational concentration process part feature for placer, the technological ability to transform the in situ massif placer structure is evident. the two main processes involved in altering the massif in situ have been examined and outlined in detail. the in situ disintegration of massif material results in a new massif gravitational stratification structure. regula...

tendon transfers in hand patients are a commonly performed procedure after extensor tendon rupture. however, the standard side to side technique is not applicable in every patient. we present a case of a musician with unique demands to demonstrate the option to customize surgical technique and therapy regimen to the unique needs of each patient. an extensor indicis proprius to extensor digitoru...
