Establish a comprehensive plan robustness evaluation platform for intensity modulated proton therapy bilateral head and neck cancer based on the daily cone-beam computed tomography: dose accumulation study between PTV IMPT (PTV-IMPT) CTV robust optimized (ro-IMPT) planning strategies

The purpose of this study was to evaluate doses sulfur applied at topdressing, with and without organic compost supply planting, in the production, physiological quality content macronutrients lettuce seeds. Ten treatments were evaluated a 5x2 factorial scheme (five topdressing x application planting). experimental design randomized block design, four replicates. fertilization 50, 100, 150 200 ...

This paper reports the first C. radiata population with resistance to glyphosate and multiple acetolactate synthase (ALS) inhibitor, imazamox. Two populations, one putative resistant (R) susceptible (S), were used in studies. Dose–response experiments performed evaluate factor (RF). Shikimic acid accumulation, 5-enolpyruvylshikimate-3-phosphate (EPSPS) ALS enzyme activities studied together che...

conclusions intake of water extract of silybum marianum is a useful treatment for liver function in drug-induced fatty liver. results concentrations of hdl-c and protein decreased and activity of alt increased in tmx group compared with the control group. the sme increased protein concentration and decreased alt activity in tmx-sme group compared with the tmx group. histopathological examinatio...

introduction: active personal dosimeters (apds) are well accepted as useful and reliable instruments for individual dosimetry measurements. apds have many advantages compared with passive dosimeters for individual external radiation dose assessments. in routine monitoring, occupational exposure is carried out for verification and demonstration of compliance with the regulatory dose limits. so, ...

SREBP1c (sterol regulatory element-binding protein 1c) is a metabolic-syndrome-associated transcription factor that controls fatty acid biosynthesis under glucose/insulin stimulation. Oxidative stress increases lipid accumulation, which promotes the generation of reactive oxygen species (ROS). However, we know little about the role of oxidative stress in fatty acid biosynthesis. To clarify the ...

A 45-year-old woman presented with a headache and visual complaints. Brain MRI revealed a large mass in the right occipital cortex. The tumor was surgically removed and pathological examination showed papillary carcinoma originating from thyroid gland. She had a history of thyroid surgery 27 years ago indicating papillary thyroid cancer with central neck lymph node involvement followed by no ad...

The accumulation off3-carotene in serum and skin was evaluated in human volunteers. A single S I -mg dose of 3-carotene given in the absence of dietary fat resulted in no detectable change in serum /3-carotene. The same dose administered with 200 g fat increased serum /3-carotene 2.5-fold at 40 h. Similarly, administering a-carotene daily in three divided doses with meals raised the serum /3-ca...

Introduction Gallium-67 (67Ga) has been used as a radionuclide for imaging a variety of solid tumors since 1969. Since then use of various gallium-based radiotracers has been reported. Recently, 67Ga-labeled acetylacetate bis(thiosemicarbazones) (67Ga-AATS) complex with significant tumor accumulation and fast blood clearance has been employed. Materials and Methods In this study, the absorbed d...

Introduction: Gynecological malignancies present challenges in determining an appropriate volumetric dose due to the highly variable physiologic activity of the surrounding tissue. Because of the high doses used in brachytherapy, surrounding structures have the potential to move around in the dose region and receive unknown amounts of radiation. Calculating hotspot region from ...
