Resul ts of tests in 1946 showed the apparent vi tamin A potency of oil from livers of Alaskan bachelor seals to vary from 13,105 to 394,145 spec. units per gram of oil with an average value of 112,000. The oil content of livers varied from 0.20 to 2.17 percent by weight. The oil from carcass and blubber contained from 490 to 2,040 spec. uni ts of vi tamiri A per gram of oil.

PURPOSE Protection of bone marrow against radiotoxicity during radioimmunotherapy and in some cases external beam radiation therapy such as hemi-body irradiation would permit administration of significantly higher doses to tumors, resulting in increased efficacy and safety of treatment. Melanin, a naturally occurring pigment, possesses radioprotective properties. We hypothesized that melanin, w...

Abstract Background Autologous platelet-rich plasma (PRP), which contains a pool of growth factors, appears to offer an easy solution for delivering multiple factors needed tissue repair. The objective the study is compare between single versus three doses intraarticular injection in treatment early osteoarthritis knee joint. Materials and Methods A prospective comparative was done on 100 patie...

UNLABELLED Lung cancer accounts for 17% of cancer-related deaths worldwide, and most patients present with locally advanced or metastatic disease. Novel PET imaging agents for assessing vascular endothelial growth factor receptor-2 (VEGFR-2) expression can be used for detecting VEGFR-2-positive malignancies and subsequent monitoring of therapeutic response to VEGFR-2-targeted therapies. Here, w...

We previously have reported that radioiodinated anti-tenascin monoclonal antibody 81C6 exhibits therapeutic potential against both s.c. and intracranial human glioma xenografts in athymic mice and rats. Herein we report the selective tumor localization of 131I-labeled 81C6 in patients with gliomas and other intracranial malignancies. Nine patients were simultaneously administered 5-50 mg of 131...

Exposure to methanol can cause serious consequences such as permanent visual disturbances and death. The heart tissue is highly vulnerable ATP deficiency. Our study aimed investigate whether exogenous administration may alleviate methanol-induced deficiency subsequent oxidative damage in rat tissue. A total of 30 rats were divided into equal five groups; Healthy Group (HG), Methotrexate (MXG), ...

Fractal metallic dendrites have been drawing more attentions recently, yet they have rarely been explored in electronic printing or packaging applications because of the great challenges in large-scale synthesis and limited understanding in such applications. Here we demonstrate a controllable synthesis of fractal Ag micro-dendrites at the hundred-gram scale. When used as the fillers for isotro...

A digital phantom was created from a CT scan of patient’s head and employed together with GATE 8.2 Monte Carlo modeling linear accelerator nominal 6 MV energy to simulate an irradiation geometry for typical tumor volume centrally within the brain region. Although simplistic in arrangement, this setup considered appropriate demonstrate dose enhancements that may be expected megavoltage external ...

chlorotoxin is a 36 amino acids peptide, which is able to block chloride channels isolated from mouse brain. a derivative of chlorotoxin is synthesized and it is labeled by iodine 131; then animal experiments carry out on rats. multiple organ doses may be calculated with biological distribution results in rats with labeled compounds using simulated mcnp4c code. human dose can be calculated usin...
