The metathoracic femoral chordotonal organ is a joint angle receptor of the locust hindleg. It consists of 45-55 bipolar sensory neurones located distally in the femur and mechanically coupled to the tibia. Responses of receptors of the organ were examined by extracellular and intracellular recording. The organ as a whole encodes the angle of the femorotibial joint but shows substantial hystere...

background:  this study presents patient specific and organ dose estimation in computed tomography (ct) imaging of thorax directly from patient ct image using monte carlo simulation.  patient's ct image is considered as the patient specific phantom and the best representative of patient physical index in order to calculate specific organ dose. materials and methods: egsnrc /beamnrc monte c...

conclusions it should be kept in mind that the oral flora bacterium s. anginosus may cause transient bacteremia and deep-seated organ abscesses in immunodeficient patients with poor oral hygiene. such patients with intra-abdominal abscesses should be treated with antibiotics and surgery. introduction the streptococcus anginosus group of bacteria are low-virulence bacteria existing as commensals...

Background: CT is a diagnostic imaging modality giving higher patient dose in comparison with other radiological procedures, so the calculation of organ dose in CT exams is very important. While methods to calculate the effective dose have been established (ICRP 26 and ICRP 60), they depend heavily on the ability to estimate the dose to radiosensitive organs from the CT procedure. However, dete...

hydatid disease is the most common infections worldwide, but it rarely involves multiple organs. herein, a 12-year-old boy is presented, who was admitted to children's medical center, tehran university of medical sciences, tehran, iran with symptoms of irritability, sleepless, and weak­ness of the extremities. patient's brain computed tomography (ct) scan with contrast media showed large multil...
