Mast cells are a key cell in the innate immune system. These tissue resident and considered to act as sentinels for detection of multitude different ligands. Activation mast via stimulation IgE receptors underlies allergic reactions food, pollen, pet dander, many other allergens. Stimulation results their activation leading degranulation – process which releases extracellular mediators like his...

BACKGROUND The most common hereditary hemoglobin disorder, affecting 20 million individuals worldwide, is sickle cell disease. The vascular obstruction resulting from the sickling of cells in this disease can produce local hypoxemia, pain crises and infarction in several tissues, including the bones, spleen, kidneys and lungs. OBJECTIVE To determine red blood group genes in a Brazilian popula...

Of all the components of the culture medium, only CaCl2 induces DNA replication when added to resting cultures of Balb/c 3T3 cells. The effect is present even in a serum-free medium. Increasing the Ca++ concentration above the standard 1.8 mM in the medium of a new culture increases the total number of cells ultimately produced, without affecting the initial cell growth rate. This effect is syn...

An adrenal cortical cell rest, an interstitial cell, and a pleuripotent cell have all been suggested as the origin of testicular masses in congenital adrenogenital syndrome. 2 Embryologically the development of the adrenal gland and the genital ridge occurs in close proximity. Adrenal cell rests are therefore known to occur in the spermatic cord, testis, broad ligament, and the ovary. The norma...

low calorie diets are always difficult for obese subjects to follow and lead to metabolic and behavioral adaptation. therefore, we evaluated the effect of caffeine treatment with calorie shifting diet (csd) on weight loss. female subjects (n=98; bmi≥25) completed 4-weeks control diet, 6-weeks csd (3 repeated phases; each 2-weeks) and 4-weeks follow-up diet, with or without caffeine treatment (5...

background: although parental obesity is a well-established predisposing factor for the development of obesity, associations between regional body compositions, resting metabolic rates (rmr), and physical activity (pa) of parents and their pre-school children remain unknown. the objective of this study was to investigate parent-child correlations for total and regional body compositions, restin...

The cross talk between NK cells and macrophages is emerging as a major line of defense against microbial infections and tumors. This study reveals a complex network of soluble mediators and cell-to-cell interactions allowing human classically activated (M1) macrophages, but not resting (M0) or alternatively activated (M2) macrophages, to prime resting autologous NK cells. In this article, we sh...
