We present an entirely novel, self-limiting photolithography mechanism in off-stoichiometry thiol-ene (OSTE) polymers enabling high-resolution and high-aspect ratio features. The OSTE polymers have previously been shown to be promising materials for fabrication of microfluidic devices with tailored surface modifications and mechanical properties. We here introduce direct lithography for micropa...

In radiofrequency ablation (RFA), successful therapy requires accurate, image-guided placement of the ablation device in a location selected by a predictive treatment plan. Current planning methods rely on geometric models of ablations that are not sensitive to underlying physical processes in RFA. Implementing plans based on computational models of RFA with image-guided techniques, however, ha...

background : there are various variables such as the duration and the client consistency' in using a special contraceptive method as well as some individual determinants. which play important roles in optimal using of different contraceptive methods. iud cu- 380a is a safe and an effective method used by 12.5% urban women in east azarbaijan. correlation between continuation rate of using iud cu...

intrauterine device (iud), a conventional method of contraception is rarely associated with uterine perforation and extra uterine dislocation. a 29 years old woman complaining of vaginal bleeding was referred for pelvic mass identified in ultrasound. the mass was confirmed with ct scan. in laparatomy we found an iud in cul-de-sac and pelvic mass was apparently an organized hematoma. transmigrat...

patients and methods the current quasi-experimental study was conducted on 96 eligible females, who were allocated either to the case or the control group and were selected from homes in the border of zahedan city (southeast of iran) during 2010. convenience sampling by door-to-door visits was used for finding eligible cases. a ttm-based self-administrated family planning questionnaire was used...

Brace treatment for idiopathic scoliosis in skeletally immature children is the only effective nonoperative modality for the control of curve progression. The Charleston bending brace is a custom-molded spinal orthosis that holds the patient in a completely corrected or overcorrected position while worn at night. A 9-year-old girl presented with 10° right upper thoracic and 7° left lower thorac...

conclusions some of the noninvasive body contouring devices in animal and human studies such as cryolipolysis, rf, lllt and hifu showed statistical significant effects on body contouring, removing unwanted fat and cellulite in some body areas. however, the clinical effects are mild to moderate, for example 2 - 4 cm circumference reduction as a sign of subcutaneous fat reduction during total tre...

nanotechnology is the engineering of functional systems at the molecular scale which may exert a revolutionary impact on cancer diagnosis and therapy. nanotechnology is being applied to cancer in two broad areas: i) the development of nanovectors such as nanoparticles which can be loaded with drugs or imaging agents and then targeted to tumours, and ii) high-throughput nanosensor devices for de...
