Background: Vegeta on (food stuff) is grown in soil that contains many radioac ve elements such as 238 U (uranium), 232 Th (thorium) and 40 K (potassium), which may get deposited either due to radioac ve fallout or/and by absorp on from the soil and can pose serious health hazards. Materials and Methods: Natural radioac vity, radiological hazards and annual effec ve dose assessment was carried ...

SUMMARY The inhibition of tumorigenesis by various agents possessing known biochemical and/or biologic effects has been examined using mouse skin initiation-promotion experiments. The agents were applied on mouse skin at various time intervals with respect to the initiating treatment with 7,1 2-dimethylbenz(a)-anthracene. Actinomycin D and aflatoxin B1 were most effec tive 30 and 7 days after i...

This study estimates progressivity of out-of-pocket (OOP) health payments and their determinants using South African Income Expenditure Surveys. Concentration is decomposed to examine the effec...

Recent studies in both human and murine systems have suggested that natural killer (NK) t activity can be mediated by different populations of effector cells (1-3). In human peripheral blood, most NK cells were found in the null cell fraction (4) and were morphologically identified as large granular lymphocytes (LGL) (5). When analyzed with monoclonal antibodies directed at well-defined surface...

T HE industrial sector has long been regarded as the stepchild of marketing in terms of the amount of research effort devoted to its problems. There are, however, indications that the situation may be changing. Research on industriallorganizational buying behavior is growing, and a considerable body of empirical knowledge about processes surrounding the innovation and diffusion of industrial te...

Free radicals are substances normally produced by the human body as one of the defense mechanisms against harmful substances. When the rate of their production exceeds the antioxidant capacity of the body, oxidative stress occurs. Oxidative stress carries harmful effects to all the body systems and is implicated in the pathogenesis of various diseases including hypertension, atherosclerosis, di...

Background: Radia on absorbed dose to the red bone marrow, a cri cal organ in the therapy of thyroid carcinoma, is generally kept below 2 Gy for non-myeloabla ve therapies. The aim of this study was to calculate bone marrow radia on dose by using MIRDOSE3 package program and to op mize the safe limit of ac vity to be administered to the thyroid cancer pa ents. Materials and Methods: In this stu...

A planar nonlinear weak form quadrature beam element of arbitrary number axial nodes is proposed on the basis absolute nodal coordinate formulation (ANCF). Elastic forces are established through geometrically exact theory, resulting in good consistency with classical theory. Two examples strong geometrical nonlinearity presented to verify effec-tiveness formulation.

introduction: addiction is a habit or behavior that is often hard to quit. it is estimated that 190 million persons are substance users around the world. substance abuse creates tolerance after a while. shortly after taking the drug, a person will not enjoy as the beginning of its use that is why the amount of substance used is gradually increased. the purpose of this study was to find the reas...
