This study reports measurements of the skin surface temperature elevations during localized irradiation (94 GHz) of three species: rat (irradiated on lower abdomen), rhesus monkey (posterior forelimb), and human (posterior forearm). Two exposure conditions were examined: prolonged, low power density microwaves (LPM) and short-term, high power density microwaves (HPM). Temperature histories were...

Extraneural metastases of intracranial germinoma are rarely reported. The authors describe the first case of metastatic lung germinoma of the thoracic spine. A 27-year-old man presented with right shoulder pain and right upper limb weakness. He had a history of repetitive radiation therapy - nine (whole-abdomen; 15Gy), 12 (whole brain; 30Gy, whole spine 42Gy) and 14 years ago (local; 32Gy) - fo...

PURPOSE Radiation induces apoptosis as a result of damage to cellular DNA and RNA. The aim of our work was to study the effect of radiation on rat bone marrow cells (as a neighboring tissue) in the context of a model of experimental radiation enteritis in rats. The effect of systematic administration in irradiated animals of r-IGF-1 and GH was also studied. MATERIALS AND METHODS Wistar type, ...

X-irradiation of eggs and larvae of Oncopeltus fasciatus results in the development of clonal patches of epidermal cells of unusual pigmentation. The frequency, size and distribution of these patches is dependent on the dose and timing of irradiation. Analysis of these clones in the abdomen has shown that the presumptive epidermis becomes effectively segmented during blastoderm formation and th...

Background: In most cancer cases, the treatment choice for a pregnant patient is radiotherapy. In these patients, the abdomen is usually not exposed therefore fetus exposure is due to peripheral dose (PD). The purpose of this study was to estimate the fetal dose (the maximum PD in each pregnancy stage) for modalities available and to fabricate and evaluate a generally applicable fetal ...

early detection of free air in the peritoneal cavity is vital in diagnosis of life-threatening emergencies, and can play a significant role in expediting treatment. we present a series of cases in which bedside ultrasound (us) in the emergency department accurately identified evidence of free intra-peritoneal air and echogenic (dirty) free fluid consistent with a surgical final diagnosis of a p...

background:   understanding the etiology of appendicitis is important for developing effective treatments the rela­tionship between parasitic appendicitis and various socio-cultural factors were examined, particu­larly with respect to the incidence of literacy. the aim of the article was to research the relations between para­sitic appendicitis and literacy ratio in population. methods : cases ...

omental torsion is caused by the rotation of the greater omentum on its axis which may lead to tissue infarction and necrosis. it is a rare cause of acute abdomen. signs, symptoms and paraclinical data are not specific. the patients usually undergo laparotomy for acute abdomen of poorly defined origin. high index of suspicious is required for the diagnosis of this entity. the diagnosis is usual...

Severe intraabdominal infection associated with abdominal wall, intraperitoneal and remote organ complications, still carries an unacceptably high morality rate. In addition to the fundamental principle of eradication of the source of infection, various treatment modalities have been suggested to improve the commonly grave outcome. Amongst these, open management (OM) of the septic abdomen,...

sterilized soils are commonly used for the study of xenobiotic sorption and as an abiotic control in biodegradation experiments. they are also used for the chemical study of nitrogen and carbon cycle processes and the elimination of the biological factors. in this research the effects of different soil sterilization methods such as autoclaving, fumigating and exposure to ultraviolet and microwa...
