Phosphorylation of the insulin-regulatable glucose transporter (IRGT) is increased by incubating rat adipocytes with isoproterenol or by incubating microsomal membranes with cAMP-dependent protein kinase. To attempt to locate the sites of phosphorylation, the IRGT (apparent Mr = 46,000) was immunoprecipitated from 32P-labeled adipocytes and cleaved with CNBr or trypsin. Essentially all of the 3...

Endobronchial brachytherapy (EBB) is an effective treatment for endobronchial tumors. However, bronchial toxicity caused by over-irradiation remains problematic. To decrease bronchial toxicity, we developed a source-centralizing applicator for EBB. The purpose of the present study was to assess the efficacy and safety of EBB with varying reference dose points according to the bronchial diameter...

BACKGROUND Surgery plus adjuvant radiotherapy is standard care for locally advanced prostate cancer (stage pT3R1). Intraoperative low-energy photon radiotherapy offers several advantages over external beam radiotherapy, and several systems are now available for its delivery, using spherical applicators, which require only limited shielding. The aim of this study was to evaluate the feasibility ...

INTRODUCTION In recent years, various types of medical applications of microwaves have widely been investigated and reported [1]. In particular, minimally invasive microwave thermal therapies using thin applicators are of a great interest. They are interstitial microwave hyperthermia [2] and microwave coagulation therapy (MCT) [3] for medical treatment of cancer, cardiac catheter ablation for v...

Background: One of the main problems of dedicated IORT accelerators is to determine dosimetric characteristics of the electron beams. Monte Carlo simulation of IORT accelerator head and produced beam will be useful to improve the accuracy of beam dosimetry.Materials and Methods: Liac accelerator head was modeled using the BEAMnrcMonte Carlo simulation system. Phase-space files were generated at...

Incorporation of 32P into yeast fructose-1,6-bisphosphatase (EC 3.1.3.11) was observed after addition of glucose to a cell suspension incubated with (32P)orthophosphoric acid. The 32P counts were coincident with the enzyme band when immunoprecipitates were subjected to sodium dodecyl sulfate disc gel electrophoresis. The incorporation of phosphate was associated with a decrease in enzyme activi...
