Objectives of this study were to (1) determine the starch physicochemical properties of two commercial Tibetan hull-less barley varieties, Beiqing (BQ) and Kangqing (KQ); and (2) understand the relationship between unique properties of the starches, their structures, and impacts of growing conditions. The BQ barleys were grown at a location with lower temperature and less rainfall compared with...
OBJECTIVES To compare caesium-137 concentrations in patients from the Western Isles Health Board, Glasgow area, and other parts of the Scottish mainland, and to investigate the source of 137Cs in patients from the Western Isles. DESIGN Study of hypertensive patients having electrolyte concentrations measured, including 137Cs. Interview by questionnaire of island subjects about intake of foods...
OBJECTIVE To evaluate the association between the International Prostate Symptom Score (IPSS) bother question (BQ) and a validated disease-specific quality-of-life questionnaire, the Benign Prostatic Hyperplasia (BPH) Impact Index (BPH-II), using the BPH Registry and Patient Survey database. PATIENTS AND METHODS The BPH Registry and Patient Survey is a multicentre, longitudinal, observational...
Increased endothelin-1-mediated vasoconstrictor tone has been linked to the etiology of a number of pathologies associated with human aging, including hypertension, congestive heart failure, and coronary artery disease. However, it is currently unclear whether aging, per se, is associated with enhanced endothelin-1 system activity. We hypothesized that endothelin-1 vasoconstrictor activity is g...
Benzene is an occupational toxicant and an environmental pollutant that is able to induce the production of reactive oxygen species (ROS), causing oxidative stress and damages of the macromolecules in target cells, such as the hematopoietic stem cells. We had previously found that embryonic yolk sac hematopoietic stem cells (YS-HSCs) are more sensitive to benzene toxicity than the adult bone ma...
OBJECTIVE To determine the risk of lung cancer associated with exposure at home to the radioactive disintegration products of naturally occurring radon gas. DESIGN Collaborative analysis of individual data from 13 case-control studies of residential radon and lung cancer. SETTING Nine European countries. SUBJECTS 7148 cases of lung cancer and 14,208 controls. MAIN OUTCOME MEASURES Relat...
Cytochrome P450 (CYP) 2E1 was the most efficient CYP enzyme that oxidized benzene to soluble and covalently bound metabolites in rat and human liver microsomes. The covalent binding was due mostly to the formation of benzoquinone (BQ), the oxidation product of hydroquinone (HQ), and was inversely related to the formation of soluble metabolites. In rats, inhalation of benzene (4 mg/liter of air)...
In this note we determine the Bernstein-Sato polynomial bQ(s) of a generic central arrangement Q = ∏k i=1 Hi of hyperplanes. We establish a connection between the roots of bQ(s) and the degrees of the generators for the top cohomology of the corresponding Milnor fiber. This connection holds for all homogeneous polynomials. We also introduce certain subschemes of the arrangement determined by th...
The objective: to compare treatment efficacy of pulmonary tuberculosis patients with multiple (MDR) and extensive drug resistance (XDR) using a standard chemotherapy regimen the containing bedaquiline. Subjects Methods. A retrospective study was conducted analyze outcomes in 219 MDR/XDR Mycobacterium (MTB) aged 18-75 years old who were treated in-patient out-patient facilities St. Petersburg from...
آشکار سازهای cr-39 بصورت وسیع در اندازگیری گاز رادن و دختران آن در هوا مورد استفاده قرار میگیرند . سعی شده است که با استفاده از شبیه سازی مونت کارلو امکان استفاده مستقیم cr-39 برای اندازگیری رادن و دختران آن در آب بررسی شود . باتصادفی فرض کردن موقعیت وزاویه ارسال ذرات آلفای رادن ودختران آن ضریب حساسیت آشکار ساز cr-39 در هوا , آب, هگزان,روغن زیتون و سیکلوهگزان محاسبه شده است. استفاده از cr-39 در...
