BACKGROUND Detection of latent tuberculosis infection (LTBI) in transplant candidates is very important. The tuberculin skin test (TST) and interferon-gamma release assays (IGRAs) are standard immunologic tools for LTBI detection. The aim of this study was to compare the TST results and T-SPOT(®).TB test (a type of IGRAs) in kidney transplant candidates for the screening of LTBI and follow the ...

In this paper energy bands and Berry curvature of graphene was studied. Desired Hamiltonian regarding the next-nearest neighbors obtained by tight binding model. By using the second quantization approach, the transformation matrix is calculated and the Hamiltonian of system is diagonalized. With this Hamiltonian, the band structure and wave function can be calculated. By using calculated wave f...

one of the most important advantages of particle simulation as compared to fluid simulation is the capacity for working with and tracing particles. in particle simulations, the test particle method is usually used to get some idea of the behavior of plasma or other substances. in this method, first, a small number of particles are injected into the frame of static electromagnetic fields. then, ...

Background Antihyperglycemic effects of Panax ginseng berry have never been explored in humans. The aims of this study were to assess the efficacy and safety of a 12-wk treatment with ginseng berry extract in participants with a fasting glucose level between 100 mg/dL and 140 mg/dL. Methods This study was a 12-wk, randomized, double-blind, placebo-controlled clinical trial. A total of 72 part...

Goji berry (wolfberry), a member of the Solanacea family, has been recently introduced in Western countries and its consumption has increased rapidly. The objectives of the study were to describe the cases of 2 patients who experienced allergic symptoms after Goji berry consumption, to identify the protein profile of the extract, to analyze the allergenic profile of individuals, and to determin...

We describe a simple, noninstrumental procedure for detecting hemoglobin S in samples of blood on filter paper, with use of small volumes of reagents. The method depends on the differential solubilities of reduced sickling and nonsickling hemoglobin in phosphate solutions (1, 2) or Sickledex reagent’ and the apparent solubilizing effect of urea on reduced hemoglobin S (3). The color of paired p...

Lycium barbarum (goji berry) has long been used as a food and traditional herbal medicine. This study aimed to investigate the beneficial effect of the goji berry on dry eye disease in rats. Male Sprague‑Dawley rats with induced dry eye disease were randomly assigned to four groups: Vehicle (control), low‑dose goji berry extract [GBE; 250 mg/kg/body weight (bw)], median‑dose GBE (350 mg/kg/bw),...
