in the process of learning basic biochemistry, as in any other area, much extra class work is required for students before basic concepts, such as those concerning protein structure and properties, are firmly settled. to reach this end we have developed a simple instruction method to teach protein structure in biochemistry courses for medical students. the objectives of this method are to illus...

the most frequent adverse effects of indomethacin like other nsaids are gastro–intestinal and central nervous system disturbances. extended release or enteric release formulations minimize these symptoms. the objective of this study was to develop an extended release pellet formulation of indomethacin by the centrifugation (rotary fluid bed granulation) or powder layering method. layered, nonpa...

the aim of this study was to compare the lateral window and osteotome techniques for sinus lifting using histological and histomorphometric methods.in this clinical trial 10 patients (a total number of 14 sinus areas) who needed implant treatment in the atrophic posterior maxilla were enrolled. in all the cases the residual bone height between the sinus floor and the alveolar crest was less tha...

several appliances have been used for palatal expansion for treatment of posterior cross bite. the purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (fem) analysis.two 3d fem models were designed ...

pseudoaneurysms (psa) of deep femoral artery (dfa) have been reported following penetrating and blunt trauma to the thigh and orthopedic procedures of the proximal femur. we describe a case of pseudoaneurysm of dfa as a late complication of limb trauma which was confirmed by exploration in an urgent surgery. after two operations successful surgical repair was performed.

background:  parts of the implants placed over the meniscus during meniscal repair can wear down the cartilage in the contact zones and cause chronic synovitis. placing horizontal sutures under the meniscus may overcome this potential hazard. the purpose of this prospective study was to evaluate the midterm results of arthroscopic meniscal repair using submeniscally placed out-in horizontal sut...

background: when non-operative treatment of tennis elbow fails; a surgical procedure can be performed to improve the associated symptoms. different surgical techniques for treatment of lateral epicondylitis are prescribed. the purpose of this study was to evaluate the clinical outcomes of surgical treatment for tennis elbow based on small incision techniques.   methods: this technique was perfo...

background: hyperbilirubinemia is a common physiological problem in approximately 80% of preterm infants during the first week after birth. increase in bowel movements reduces enterohepatic circulation and increases bilirubin excretion. aim: this study aimed to evaluate the effects of field massage technique on bilirubin level and the number of defecations in preterm infants method: this clinic...

poor inhaler technique is a common problem both in asthmatic patients and healthcare providers, which contributes to poor asthma control. this study was performed to evaluate the adequacy of metered-dose inhaler (mdi) technique in a sample of physicians and nurses practicing in hospitals of hamadan university of medical sciences. a total of 173 healthcare providers voluntary participated in thi...

â â â  â â â â â  abstract: â  up to now, the impact of real exchange rate on the non-oil exports of iran has been mainly on focus. however, the more important aspect of the fluctuations in exchange rate is its degree of volatility which can have profound effect on the non-oil exports. hence, the main objective of this paper is to investigate the linkage between non-oil exports and the real exc...
