This study was conducted to evaluate the effect of soy milk on serum 17- β estradiol level and number of neurons in cerebral cortex and hippocampus as well as determination of the ratio of neurons in cortical and hippocampal regions in neonatal ovariectomized rats. Thirty female rats (one day old) were divided into six groups of five. At day 7, ovariectomy surgery was performed in four groups a...

BACKGROUND Bone loss increases after menopause. However, bone strength also depends on structural characteristics such as bone size. Whether bone size increases as a result of periosteal apposition and whether a strength index accounting for both bone density and bone size might predict the risk of fracture better than bone density alone are unclear. METHODS Bone mass and the skeletal structu...

OBJECTIVE To evaluate the correlation between bone tunnel diameter after anterior cruciate ligament (ACL) reconstruction measured by computed tomography (CT) using multiplanar reconstruction (MPR) and stability or clinical scores. MATERIALS AND METHODS Forty-seven patients (41 men and 6 women, mean age: 34 years) who had undergone ACL reconstruction with the double bundle technique using auto...

OBJECTIVES Implant osseointegration is dependent upon various factors, such as bone quality and type of implant surface. It is also subject to adaptation in response to changes in bone metabolism or transmission of masticatory forces. Understanding of long-term physiologic adjustment is critical to prevention of potential loss of osseointegration, especially because excessive occlusal forces le...

among the rare bone tumors, the osteoblastoma is a fascinating tumor. the rarity, the predisposition to occur in any bone and the diagnostic dilemma makes this infrequent tumor interesting. it is sporadically reported in the literature and what is rarer is its occurrence in the pelvis. the unusual location and inconclusive radiographic findings with diffused diagnostic evidences delays the mana...

there are some conflicts about constancy of conduction velocity (cv) in a given tract of nervous system. by recording excitatory postsynaptic currents (epsc) in layer iv of the somatosensory cortex we tried to clear changes in cv of thalamocortical tract of mice aged 3 to 50 days old. field potentials and epsc were recorded in the layer iv by stimulation of ventrobasal nucleus of thalamus (vb) ...

Celiac disease (CD) is currently considerably underdiagnosed, setting the need for developing tools to select patients with probability of CD, who warrant further testing. Red blood cell distribution width (RDW) has been shown in previous studies to be a sensitive predictor for CD, but it lacks specificity. Splenic hypotrophy is also noted frequently in celiac patients. Our aim was to evaluate ...

The S-shaped clavicle poses a problem for intramedullary pin fixation. Stability of fracture fixation is closely related to the length of intramedullary pin engagement. This study was carried out to determine the engagement length of intramedullary pins into clavicular fractures using a small and a large pin. Seven pairs of fresh cadaveric clavicles were prepared and arranged into Group 1 and G...

This study was performed to evaluate the effect of betatricalcium phosphate and poly L-lactide-co-glycolide-coepsilon- caprolactone (TCP/PLGC) membrane in the repair of partial bone defects in canine proximal humerus. Three adult mixed-breed dogs were used during the experimental period. The length of the defect was quarter of the full length of humerus, and width of the defect was quarter of m...
