background : peroxisome proliferator-activated receptor gamma (ppar γ) is a transcription factor, which is abundantly expressed in adipose tissue and has a direct link to adiposity. it seems that long-chain polyunsaturated fatty acids (lc-pufas) can regulate ppar γ expression. the purpose of this study was to investigate the effects of n-3lc pufa supplementation on plasma levels of ppar γ and t...

BACKGROUND Mutagen-induced DNA damage as measured in peripheral blood lymphocytes (PBL) has been associated with increased risks of cancers. The formation of γ-H2AX is an early cellular response to DNA double-strand breaks (DSB). We hypothesize that higher level of radiation-induced γ-H2AX in PBLs may be associated with an increased risk of esophageal adenocarcinoma. METHODS Laser scanning cy...

The mechanism(s) underlying renoprotection by peroxisome proliferator-activated receptor (PPAR)-γ agonists in diabetic and nondiabetic kidney disease are not well understood. Mitochondrial dysfunction and oxidative stress contribute to kidney disease. PPAR-γ upregulates proteins required for mitochondrial biogenesis. Our aim was to determine whether PPAR-γ has a role in protecting the kidney pr...

We present the first of two articles on the small volume fraction limit of a nonlocal Cahn–Hilliard functional introduced to model microphase separation of diblock copolymers. Here we focus attention on the sharp-interface version of the functional and consider a limit in which the volume fraction tends to zero but the number of minority phases (called particles) remains O(1). Using the languag...

We study, by means of Γ-convergence, the asymptotic behaviour of a variational problem modeling a dislocation ensemble moving on a slip plane through a discrete array of obstacles. The variational problem is a two dimensional phase transition type energy given by a non local term and a non linear potential which penalizes non integer values. In this paper we consider a regime corresponding to a...

cytokines have been introduced as critical inducers in the development of th subpopulations.cytokines like il-10 are involved in inducing regulatory t cells such as type 1 regulatory t (tr1) cells cells. il-22 is a member of il-10 family of cytokines, and il-28a is a member of ifn-γ family. in this study, cord blood mononuclear cells (cbmc) from normal healthy individuals were isolated by ficol...

Background: Brucella is a gram-negative bacterium, causing acute and chronic infection in humans and animals. Cell-mediated immunity is the main protective immune response against Brucella spp. Activation of macrophages by IFN-γ and generation of reactive oxygen intermediates and nitric oxide are the main immunologic mechanisms responsible for control of Brucella infection. Objective: To invest...

The aim of this study was to investigate the immunomodulatory effects of Spirulina platensis (S.platensis) by measuring the levels of serum interleukin (IL)-4, IL-10, IL-17, tumor necrosis factor(TNF)-α and interferon (IFN)-|γ| in mice suffered from systemic candidiasis and breast cancer. Theaqueous extract of S. platensis was selected for this study. Balb/C female mice were inoculated withCand...
