background : stomach cancer is one of the most common malignancies worldwide. in iran, the mortality of stomach cancer is the first cause of death due to cancer in both sexes. this study was designed to estimate survival rate of stomach cancer at national level. methods : from the national cancer registry file, 3439 cases of stomach cancer that had telephone number and were diagnosed between ye...

background: variations of the brachial plexus are common and a better awareness of the variations is of crucial importance to achieve successful results in its surgical procedures. the aim of the present study was to evaluate the anatomical variations of the brachial plexus in adult cadavers.   methods: bilateral upper limbs of 32 fresh cadavers (21 males and 11 females) consecutively referred ...

injuries to the posterolateral corner (plc) comprise a significant portion of knee ligament injuries. a high index of suspicion is necessary when evaluating the injured knee to detect these sometimes occult injuries. moreover, a thorough physical examination and a comprehensive review of radiographic studies are necessary to identify these injuries. in this sense, stress radiographs can help to...

Because of the recent trend for total hip arthroplasty in younger patients, more bone-preserving implants have been designed, based partly on the premise that maintenance of more bone stock would allow revision with standard primary implants. Another possible advantage of an implant that retains the femoral neck is that it may allow anatomical recreation of the center of the femoral head, femor...

Fast and robust detection of anatomical structures or pathologies represents a fundamental task in medical image analysis. Most of the current solutions are however suboptimal and unconstrained by learning an appearance model and exhaustively scanning the space of parameters to detect a specific anatomical structure. In addition, typical feature computation or estimation of meta-parameters rela...

Mechanist philosophers have examined several strategies scientists use for discovering causal mechanisms in neuroscience. Findings about the anatomical organization of the brain play a central role in several such strategies. Little attention has been paid, however, to the use of network analysis and causal modeling techniques for mechanism discovery. In particular, mechanist philosophers have ...

BACKGROUND To assist in the treatment of gait disorders, an inverse and forward 3D musculoskeletal model of the lower extremity will be useful that allows to evaluate if-then scenarios. Currently available anatomical datasets do not comprise sufficiently accurate and complete information to construct such a model. The aim of this paper is to present a complete and consistent anatomical dataset,...

PURPOSE The human femur has long been considered to have an anatomical anterior curvature in the sagittal plane. We established a new method to evaluate the femoral curvature in three-dimensional (3D) space and reveal its influencing factors in Chinese population. METHODS 3D models of 426 femurs and the medullary canal were constructed using Mimics software. We standardized the positions of a...

Abstract Ninebark ( Physocarpus opulifolius ) is an attractive ornamental shrub with poor rooting characteristics in some cultivars, which a limiting factor commercial production This study was designed to optimize conditions of ninebark cuttings and observe the effect exogenous auxin IBA on morpho-anatomical biochemical changes associated rhizogenesis vitro conditions. Both auxins under study:...
