background: radiation dose knowledge through xray examinations and their distribution in iran provides useful guidance on patient dose reduction. the results of the entrance skin dose (esds) of five common radiographies in all radiology centers in yazd province were reported in our previous study (2003). in the present study we have evaluated the collective effective dose of conventional x-ray ...
OBJECTIVES In 2009-2010 a Portuguese consortium was created to implement the methodologies proposed by the Dose Datamed II (DDM2) project, aiming to collect data from diagnostic X-ray and nuclear medicine (NM) procedures, in order to determine the most frequently prescribed exams and the associated ionizing radiation doses for the Portuguese population. The current study is the continuation of ...
In a previous study we showed that the administration of gossypol to rats for 34 days caused 2 types of modification of the epididymis: (1) the secretion of carnitine and inositol were reduced in the fluid, (2) the spermatozoa lost their motility and showed major morphological changes (head-flagella dissociation). We wished to clarify the early effects of gossypol on the epididymis. Sprague Daw...
The Sertoli cells were regarded as the only target for FSH in male reproductive system. The expression of FSH receptor (FSH-R) was detected also in epithelial cells of the caput epididymis of rat and monkey. We showed in the immunohistochemistry study the expression of FSH-R in rat and human ductuli efferentes and the caput, corpus, and cauda epididymis, moreover, by Western blot analysis in th...
BACKGROUND The frequency of CT procedures has registered a significant increase over the last decade, which led at the international level to an increasing concern on the radiological risk associated with the use of CT especially in paediatrics. This work aimed at investigating the use of computed tomography in Switzerland, following the evolution of CT frequency and dose data over a decade and...
The largest man-made contributor to the ionising radiation dose to the Australian population is from diagnostic imaging and nuclear medicine. The last estimation of this dose was made in 2004 (1.3 mSv), this paper describes a recent re-evaluation of this dose to reflect the changes in imaging trends and technology. The estimation was calculated by summing the dose from five modalities, computed...
Release of testosterone from silastic implants over a period of 90 days resulted in variable stimulation of the epididymis and accessory glands of reproduction in the castrated rhesus monkey. While the weights of the seminal vesicles, prostate gland and bulbo-urethral glands were maintained at the same level as the intact control animals by four or eight implants of testosterone, those of the e...
Studies on the distribution of Na+, K+-dependent, Mg2+ dependent and Ca2+ dependent Adenosine Triphosphatase (ATP-ases) in the testes, epididymis, seminal vesicles and prostate glands of mature bonnet monkeys were carried out with and without Testosterone propionate (TP) treatment. Comparatively, the Ca2+ dependent ATP-ase was very active in the testes, caput and cauda epididymis and prostate o...
