Atropine (AT) and dipyrone (Dp) induce a delay of gastric emptying (GE) of liquids in rats by inhibiting muscarinic receptors and activating β2-adrenergic receptors, respectively. The objective of the present study was to determine the effects of pretreatment with AT and Dp, given alone or in combination, on the effect of hypoglycemia in the liquid GE in rats. Male Wistar adult rats (280-310 g)...

Let n,k,r and t be positive integers, and let [n] = {1,2, . . . ,n}. A family G ⊂ 2[n] is called r-wise t-intersecting if |G1∩·· ·∩Gr| ≥ t holds for all G1, . . . ,Gr ∈ G . Let us define a typical r-wise t-intersecting family Gi(n,r, t) and its k-uniform subfamily Fi(n,k,r, t), where 0 ≤ i ≤ ⌊n−t r ⌋, as follows: Gi(n,r, t) = {G ⊂ [n] : |G∩ [t + ri]| ≥ t +(r−1)i}, Fi(n,k,r, t) = Gi(n,r, t)∩ ([n...

Bone marrow-derived mesenchymal stem cells (MSC) are a potential attractive source of cells for stem cell-based tissue regeneration, but the small number and reduced capabilities of MSC proliferation and differentiation due to in vitro replicative senescence and donor-associated pathophysiological factors, including age and estrogen depletion, severely restrict their potential usefulness in cli...

OBJECTIVE To examine the environmental effects on cytosine methylation of preterm infant's DNA, because early life experiences are considered to influence the physiological and mental health of an individual through epigenetic modification of DNA. DESIGN A prospective cohort study, comparison of epigenetic differences in the glucocorticoid receptor (GR) gene between healthy term and preterm i...

Composite materials are manufactured by the combination of two or more distinct materials. The different form characteristics composites. Solid and stiff reinforcement is often inserted into a ductile matrix in aluminium-reinforced composites, which aim to increase mechanical properties, particularly strength, strength-to-weight ratio, etc. This study was focused on preparation data tensile pro...
