Mitotic spindles in epithelial cells are oriented in the plane of the epithelium so that both daughter cells remain within the monolayer, and defects in spindle orientation have been proposed to promote tumorigenesis by causing epithelial disorganization and hyperplasia. Previous work has implicated the apical polarity factor aPKC, the junctional protein APC2, and basal integrins in epithelial ...

OBJECTIVE To investigate the spatial pattern of lesion dispersion in posterior interosseous neuropathy syndrome (PINS) by high-resolution magnetic resonance neurography. METHODS This prospective study was approved by the local ethics committee and written informed consent was obtained from all patients. In 19 patients with PINS and 20 healthy controls, a standardized magnetic resonance neurog...

BACKGROUND Pediatric supracondylar humerus fractures are the most common elbow fractures seen in children, and account for 16 % of all pediatric fractures. Closed reduction and percutaneous pin fixation is the current treatment technique of choice for displaced supracondylar fractures of the distal humerus in children. The purpose of this study was to determine whether pin diameter affects the ...

the presentstudy aimed to compare the annual soil loss prediction of rusle model with the soil erosion measurements using erosion pins and plots in khamesan representative watershed, kurdistan province. for this purpose, the distributed annual soil loss was estimated by rusle model. the suspended sediment samples were then collected daily for one year (2015/7 to 2016/6) in hydrometry station at...

In this paper, we present a novel program synthesis approach that is inspired by symbolic testing. We symbolically execute an unknown template program and constrain the program’s behavior over each executed path. As more paths are explored the space of candidate programs narrows until only the valid ones remain. Instead of randomly picking paths, we find that is possible and more efficient to d...

BACKGROUND The most common position of malreduced type III supracondylar humerus (SCH) fractures is internal rotation and medial collapse of the distal fragment. The purpose of this study was to determine the effect of SCH fracture rotational deformity on stability with various pin configurations. Specifically, is the biomechanical stability lost when an SCH fracture is pinned in slight malredu...

Background: Although foreign body ingestion is a common problem, poor knowledge for the treatment still remains a major obstacle, especially in preventing complications. Phosphate enemas were applied for chronic constipation and bowel cleansing for a long period of time. This study aims to evaluate the effect of phosphate enema on bowel movements in patients who suffer from foreign body ingesti...

PURPOSE To compare the use of the halo fixation device in our hospital before and after implementation of a new compliance protocol. METHODS From 2003 to 2008, 17 (47%) of 36 patients had dislodgement of their halo fixation device. All rings and vests and some of the pins were reused. Documentation of poundage assessment and change of skull pins before dislodgement was lacking. There was no p...

Comeld” is a novel technology which can be applied in connecting composites and metals by manufacture of an array of metal pins on the metal part and layup the composite layers on the pins to make an adhesive and mechanical Joint at the same time. The aim of this paper is an experimental, numerical and analytical investigation on strength of comeld joint system and also to calculate the stiffne...
