progressive loss of bone mineral density around the femora! component of total hip replacement continues to pose a threat to long term prosthetic survival. a linear study was undertaken to measure bone mineral density on a monthly basis following total hip arthroplasty in 11 male patients. the opposite femur was used as the control measurement. bone mineral density was unchanged at two months f...

fenfluramine, an anorexigenic agent, is widely used in the treatment of obesity. besides its anorectic effect, it may also have some effects on general metabolism with the consequence of weight loss. in this study, the effect of fenfluramine on the concentrations of some parameters related to carbohydrate metabolism was investigated. it was shown that the serum insulin level was reduced by 41 %...

Linearity, sometimes jointly with constant variance, is routinely assumed in the context of sufficient dimension reduction. It is well understood that, when these conditions do not hold, blindly using them may lead to inconsistency in estimating the central subspace and the central mean subspace. Surprisingly, we discover that even if these conditions do hold, using them will bring efficiency l...

this experiment was designed to study the effect of putrescine on quality of table grapes during storage. table grapes cvs, rishbaba and olhoghi were dipped in putrescine solutions (0, 1 and 2mm) by the method of pressure-infiltration. the results indicated that after 55 day of storage putrescine 1 mm in rishbaba and at 2mm in olhoghi cultivars were the most effective treatments in maintaining ...

original article   introduction: direct sunlight and increased heat load influence mental and physical health of workers negatively and result in performance impairment. activity reduction is a natural body response to increase in internal body temperature, and a compensatory mechanism to make body balanced. this study was carried out to estimate productivity loss due to heat exposure among ira...

no doubt, damage and losses inflicted by callosobruchus maculatus to stored products in general and chickpea in particular can be significant. the objective of this work was to evaluate the effect of the verbascum sinuatum powder on c. maculatus oviposition behavior in chickpea under laboratory conditions (30 °c, 60% relative humidity). powder of mullein plant (v. sinuatum) caused reduction in ...

background:  hip fracture management in supine position on a fracture table with biplane fluoroscopic views has some difficulties which leads to prolongation of surgery and increasing x- rays’ dosage. the purpose of this study was to report the results and complications of hip fracture management in lateral position on a conventional operating table with just anteroposterior fluoroscopic view. ...
