background the sitting position, rather than squatting, during defecation has been hypothesized to be a risk factor for colorectal cancer (crc). methods we conducted a case-control study to test this hypothesis. a total of 100 crc cases from two hospitals in iran and 100 control subjects, selected from the coronary care unit (ccu) of those same hospitals were selected for this study. we adminis...

OBJECTIVE There is uncertainty as to whether asthma has an effect on final height. We investigated using subjective and objective assessments whether untreated asthma is associated with final height, leg length and sitting height to leg length ratio in an area of Chile in which almost no one received asthma treatment. METHODS We collected data on 1232 males and females aged 22-28 years in a s...

In four groups of 10 patients, 0.5% bupivacaine 5 ml was used in spinal anaesthesia for gynaecological surgery. Group 1 received plain solution in the sitting position, group 2 plain solution in the lateral position, group 3 hyperbaric solution in the sitting position and group 4 hyperbaric solution in the lateral position. All patients were returned to the horizontal supine position, the sitti...

Continuous measurements of anterior-posterior leg position recorded from stick insects walking on a wheel were tested for relationships among spatial and temporal parameters of leg coordination. This analysis revealed that the protraction of middle and rear legs is guided by the ipsilateral front and middle legs respectively. Protraction endpoint for each rear leg shows a significant positive c...

This study was aimed to compare the variations in cerebral oxygenation, blood pressure and center-of-foot pressure after standing from sitting and supine positions at normal (22 degrees C) and high (32 degrees C) room temperatures. Thirty young adults stood up from a resting posture (sitting or supine position) and kept the static standing posture for 90 sec. Meanwhile, their center-of-foot pre...

Background: Children with achondroplasia (ACH) appear to lack a pubertal growth spurt in height.Aim To explore the height and its segments sitting leg length, large sample of ACH cases using curve modelling.Subjects methods: Height were measured longitudinally children, data analysed SITAR (SuperImposition by Translation Rotation) model, which estimates mean random effects for individuals defin...
