Background: Despite the long-standing association of macrophage migration inhibitory factor (MIF) with delayed-type hypersensitivity response, the potential role of MIF in chronic allograft nephropathy is unknown. The association between upregulation of MIF expression, macrophage and T cell infiltration and the severity of chronic allograft nephropathy suggests that MIF may be an important medi...

BACKGROUND The aim of this study was to investigate the relationship between dynamic changes of cerebral metabolism and degree of trauma in rabbit models of traumatic brain injury (TBI) by using proton magnetic resonance spectroscopy (¹H-MRS). MATERIAL AND METHODS Thirty-five Chinese rabbits were randomly divided into control, mild, moderate, and severe TBI groups. ¹H-MRS was performed 1, 6, an...

This paper investigated the effectiveness of incorporating zero-valent iron (ZVI) into electrokinetic (EK) to remediate hyper-Cr(VI) contaminated clay (2497 mg/kg). A ZVI wall was installed in the center of the soil specimen and was filled with 1:1 (w/w) ratio of granular ZVI and sand. Results show that transport of H(+) is greatly retarded by the strong opposite migration of anionic chromate i...

Preparation for radioactive iodine (RAI) therapy includes an increased serum thyroid stimulating hormone level and a low iodine diet (LID). Because of extremely high iodine intake, some physicians have advocated a more stringent LID for greater than 2 weeks in Korean patients with thyroid cancer prior to RAI therapy; however, it is very difficult to maintain a stringent LID for a longer period ...

Introduction: Clinical evaluation of iodine deficiency disorders (IDDs) is often accomplished by assessment of urinary iodine excretion (UIE) in random samples however, the utilization of 24 hour urine samples is a more reliable biomarker of nutritional iodine status. This study was designed to evaluate total goiter prevalence (TGP) and iodine/creatinine ratio among school-aged children in Urmi...

We measured concentrations of transferrin (TRF, in micrograms), and creatinine (Cr, in millimoles) in samples of untimed urine from 53 healthy subjects and 157 non-insulin-dependent diabetic (NIDD) subjects. The urinary TRF/Cr ratio was significantly higher in the NIDD group (P less than 0.001). If NIDD subjects are grouped according to their Alb/Cr ratio into normal albuminuria (Group A, Alb/C...

Background: The presence of heavy metals in the environment especially in water supplies have caused many concerns because of their toxicity and non-degradability. Hexavalent Chromium (Cr) is one of the most toxic metals which is used in many industries, so it is essential to remove it from industrial wastewater. In this study, we made a comparison between different adsorption isotherms in the ...

background: a study on the migration characteristics of 238u, 210po, 232th and 40k within the soil to the wild plants in the western ghats were carried out. materials and methods: concentrations of these radionuclides were measured in different depths of soil and from different species by employing gamma ray spectrometer and alpha counter. results: the activity concentration of these radionucli...

A positive relationship between receptor concentration and tissue responsiveness is an often-assumed and rarely tested principle in endocrinology. In salmonids, seasonal changes in levels of plasma cortisol and gill corticosteroid receptors (CRs) during the spring indicate a potential role for this hormone in the parr-smolt transformation. It is not known whether these seasonal changes result i...

The use of nuclear energy generates large amounts of different types of radioactive wastes that can be accidentally released into the environment. Soil-to-plant transfer is a key process for the dispersion of radionuclides in the biosphere and is usually described by a concentration ratio (CR) between plant and soil concentrations in radioecological models. Our knowledge of the soil-to-plant tr...
