background : colorectal cancer is the most common cancer and the second leading cause of cancer deaths. annually it is the cause of more than 500000 deaths worldwide. therefore, detection and treatment of these tumors could potentially enhance recovery and improve prognosis. this study determines the frequency of colorectal tumors among patients who underwent colonoscopies in imam khomeini hosp...

To know the characteristics of mortality from aortic aneurysms in Japan, the age-adjusted and age-specific mortality rates of the diseases were calculated based on the Vital Statistics of Japan published from the Statistics and Information Department, Minister's Secretariat, Ministry of Health and Welfare. The overall age-adjusted mortality rate increased 24.8-fold from 0.43 to 10.98 per 100,00...

We report three patients with a descending thoracic aortic aneurysm (DTAA) and a separate infra-renal abdominal aortic aneurysm (AAA) who had initial endovascular repair of the DTAA followed by repair of AAA. Endovascular stent repair of DTAA avoids the significant morbidity associated with thoracotomy and open repair. Hence more patients with multilevel aortic aneurysm may be eligible for surg...

The role of respiratory muscles in acute changes of circulation and ventilation due to acetylcholine in anaesthetized spontaneously breathing rabbits was investigated. Significant increase of end-expiratory thoracic circumference and insignificant increase of abdominal one was found and was taken as a measure of changed respiratory muscles tone. The authors emphasize the important role of the r...

Cephalopagus is a rare variety of conjoined twins. They are fused with their heads, thoracic and upper abdominal cavities. The exact mechanism for development of conjoined twins cannot be clearly explained. It appears that there is an alteration in the normal developmental process of monozygotic twins, which fail to separate from each other. We present the morphology of a cephalothoracopagus, r...

This study investigated the use of the geometric alignment of two frontal lines (the sternum and abdominal) for predicting alignment of the thoracic and lumbar spines and for measuring wheelchair-seated posture. The sternum line connects the upper sternum point and the lower sternum point. The abdominal line connects the lower sternum point and the center point between the right and left anteri...

An intersegmental reflex initiated by flexing a crayfish leg at the merocarpal joint was examined by recording reflex response latencies of cephalic, thoracic and abdominal muscles. The first response was an intrasegmental resistance reflex in the extensor muscle of the stimulated leg. Spread of the intersegmental reflex occurred in both cephalic and caudal directions. Activation of the cephali...

We present a case of motorcyclist involved in multi-vehicle motor vehicle accident (MVA), where he was rear-ended by motorcar, collided head-on into second motorcar and subsequently flung off his motorcycle. There no suggestion runover. At autopsy, the torso showed extensive brush abrasions with open wounds. Internally, there were devastating injuries, complete separation thoracic abdominal vis...

BACKGROUND Adverse aortic remodeling, such as dilation, is associated with multiple cardiovascular disease (CVD) risk factors. We sought to determine whether measures of enlarged aortic diameters improve prediction of incident adverse CVD events above standard CVD risk factors in a community-dwelling cohort. METHODS AND RESULTS Participants from the Framingham Offspring and Third Generation C...
