As a result of nuclear power plant accidents, large areas receive radioactive inputs of 137 Cs. This cesium accumulates in herbs growing in such territories. The problem is whether the herbs contaminated by radio-cesium may be used as a raw material for medicine. The answer depends on the amount of 137 Cs transfered from the contaminated raw material to the medicine. We have presented new resul...

Endoscopic submucosal dissection (ESD) is a promising procedure that enables en bloc resection of large superficial tumors in the upper gastrointestinal tract. On the other hand, ESD in the colon and rectum is technically difficult to perform because of its anatomical features. At our institution, 137 consecutive superficial colorectal tumors larger than 20 mm in diameter in 137 patients were t...

To investigate the transgenerational effects of chronic low-dose-rate internal radiation exposure after the Fukushima Daiichi Nuclear Power Plant accident in Japan, 18 generations of mice were maintained in a radioisotope facility, with free access to drinking water containing (137)CsCl (0 and 100 Bq/ml). The (137)Cs distribution in the organs of the mice was measured after long-term ad libitum...

During the operational history of the Savannah River Site (SRS), many different radionuclides have been released from site facilities into the SRS environment. However, only a relatively small number of pathways, most importantly (137)Cs in fish and deer, have contributed significantly to doses and risks to the public. The "effective" half-lives (Te) of (137)Cs (which include both physical deca...

پراکندگی فوتون های گاما به سمت عقب از سطح یک ماده را پس پراکندگی پرتوهای گاما می گویند. در این پژوهش حفاظ های سربی، آلومینیومی و آهنی به شکل دیسک به ضخامت تقریباً 1/0 سانتی متر و قطر 18 سانتی متر ، به منظور بررسی پس پراکندگی تهیه شدند. همچنین یک چشمه ی سزیم 137 بین حفاظ و آشکارساز یدورسدیم قرار داده شد و طیف گامای چشمه ثبت گردید. به منظور بررسی تأثیر ضخامت حفاظ در میزان پس پراکندگی گاما، در هر م...

background: two of the important radionuclides which are entered to environment and human diet are radium-226 (226ra) and cesium-137 (137cs). it is clear that the methods for preparation of foods such as peeling, washing, cooking or frying can affect the dose which is received by human due the to consumption of foodstuffs. an experiment has been performed at the environmental monitoring section...

0 T verse has been a subject for lively discussion among scholars for at least two centuries. Yet in spite of the length of time that the topic has been under intensive study, no generally accepted solution has emerged. (A brief survey of previous research into the topic is offered by Stuart.)’ Among the different approaches to the problem, the one that seems most productive of insights is that...

Schizophrenia is a complex genetic disease and characterized by affective, cognitive, neuromorphological, and molecular abnormalities that may have a neurodevelopmental origin. MicroRNAs (miRNAs) are critical to neurodevelopment and adult neuronal processes by modulating the activity of multiple genes within biological networks. MiR-137 as a brain-enriched microRNA, plays important roles in reg...
