Recent studies have demonstrated that orally administered thiazolidinedione ligands of the peroxisome proliferator-activated receptor-gamma can ameliorate clinical features of psoriasis in humans. Thiazolidinediones also inhibit the proliferation of psoriatic keratinocytes in monolayer and organ culture, and at least one of these agents (troglitazone) inhibits epidermal hyperplasia of human pso...

INTRODUCTION Burn injury is a medical problem as well as a social burden on the national health services in developing countries. Trace elements have important roles in wound healing and act as antioxidants. In this study, zinc (Zn) and copper (Cu) levels in plasma of burned patients and their relationship with the burn surface area and time-related pattern are determined in the admitted patien...

Block copolymers were recently used to promote gene delivery in various tissues. Using a plasmid encoding a food allergen, bovine beta-lactoglobulin (BLG), we studied the effects of block copolymers on gene expression levels and primary immune response and on further induced allergy. Block copolymers (i.e., Tetronic 304, 908, and 1107) and various quantities of DNA were injected into the tibial...

To evaluate the effects of chelated Zn/Cu/Mn on redox status, immune responses and hoof health in lactating Holstein cows, 48 head in early lactation were divided into healthy or lame groups according to their gait score. Cows were fed the same amount of Zn/Cu/Mn as sulfate salts or in chelated forms for 180 days, and foot-and-mouth disease (FMD) vaccine was injected at day 90. The results show...

a subcutaneous implantation of maccrated tumor bits (mela noma B16) into the right axillary region by a Becton Dickin son BD13 needle. Tumor growth was divided into three periods, according to tumor size. Using 65 Zn and 59 Fe, the homeostasis of zinc and iron in mice with melanomas was studied at 5†" 6days (unde tectable tumor), 10 days (medium-size tumor), and 18†" 20 days (large-size tum...

to evaluate the impact of the application of thehran municipal solid waste compost (mswc) on zinc and copper concentrations in the soil under maize (zea mays. l.) cultivation, a factorial experiment in base randomized complete block design (rcbd) with two different amounts of municipal solid waste compost (zero, 30.15 and 60 t ha-1) and time (compost applied once or twice) was performed with th...

The objective of this study was to compare zinc sources and levels of supplementation on laying hen performance. Bovan White Leghorn hens were fed one of six dietary treatments in a 2x3 factorial arrangement consisting of two zinc sources (Availa®Zn or zinc sulfate) and three levels (40, 80, or 120 ppm). Treatments were randomly assigned to 48 cages with five hens/cage. Blocks provided eight re...

An experiment was conducted on 16 crossbred bulls (about 2 years of age, 316.2+/-0.77 kg average body weight), divided into groups I, II, III and IV to study the effect of different levels of Zn supplementation from inorganic and organic sources on semen quality. The animals in the first 3 groups were supplemented with 0, 35 and 70 ppm Zn from Zn sulfate, respectively and the animals in-group I...

The possibility of alloying can not be avoided at the interface between molten brazing filler metal and base metal in brazing, so the wettability of brazing filler metal can not be easily explained theoretically. We used the original apparatus for wettability test and investigated the relation between the wettability of brazing filler metals of Ag-P-Cu and Ag-Cu-Zn-Cd systems on copper and the ...

Aims: To clarify the changes in morphometric parameters and contents of zinc (Zn) and in the relationship between these characteristics in normal and hyperplastic human prostates, a quantitative morphometry and energy-dispersive X-ray fluorescence analysis was performed. Methodology: Samples of the human prostate of mass under 30 g were obtained from randomly selected autopsy specimens of 35 me...
