TGF-β and MMPs: A complex regulatory loop involved in tumor progression
(Matrix Metalloproteinases: Biology, Functions & Clinical Implications, 2012)
Transforming growth factor-β (TGF-β) has a dual and contradictory role in cancer. It is a tumor suppressor at early stages of tumor formation by virtue of its growth inhibitory and pro-apoptotic functions. However, at later ...
Release of reactive oxygen species and production of nitric oxide in the cultures of peripheral blood leukocytes of young athletes
(Elsevier Science Inc, New York, 2012)
SKIP Downregulation Increases TGF-β1-Induced Matrix Metalloproteinase-9 Production in Transformed Keratinocytes
(Scientifica, 2012)
Transforming growth factor-beta (TGF-β1) is a potent inductor of matrix metalloproteinase-9 (MMP-9) in transformed cells. Recently, Ski-interacting protein (SKIP) has been described as a regulator of TGF-β1 signal transduction, ...
Fish oil supplementation improved liver phospholipids fatty acid composition and parameters of oxidative stress in male wistar rats
(Wiley, Hoboken, 2012)
In the present study, we examined the effects of fish oil supplementation in 3 months old male Wistar rats on changes in plasma and liver lipid metabolism and oxidative stress parameters. Twenty Wistar rats were randomly ...
Diversity and host associations of aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) in the farmlands of western Iran
(Narodni Muzeum - Prirodovedecke Muzeum, Praha, 2012)
This study presents the results of a survey of aphid parasitoids of the subfamily Aphidiinae (Hymenoptera: Braconidae) in western Iran. Thirty nine species of aphid parasitoids belonging to nine genera were collected and ...
Evidence that calf bronchopneumonia may be accompanied by increased sialylation of circulating immune complexes' IgG
(Elsevier, Amsterdam, 2012)
Immune complexes (IC) could have an important role in the pathogenesis of pre-ruminant calves' bronchopneumonia. IC are potent activators of complement and neutrophils and they might be responsible for immune protection, ...
Similar Developmental Patterns of Ghrelin- and Glucagon-Expressing Cells in the Human Pancreas
(Karger, Basel, 2012)
The pancreas appears to be a major source of ghrelin during fetal development, but the ontogeny of ghrelin cells in the human pancreas and their developmental relationship with alpha- and beta-cells remain largely unknown. ...
Different fatty acid composition of serum phospholipids of small and appropriate for gestational age preterm infants and of milk from their mothers
(Lithographia, Thessaloniki, 2012)
Background: Placental supply of fatty acids (FA) is essential for normal foetal development but in premature infants this supply is interrupted. To investigate the association of intrautrine growth restriction with serum ...
Endocrine cells in human fetal corpus of stomach: appearance, distribution, and density
(Springer Japan Kk, Tokyo, 2012)
While ghrelin cells were the most numerous during the se Since reports on endocrine cells and their kinetics in the corpus of the human stomach are limited, the aim of this study was to examine the appearance, localization, ...
Effect of acute heat stress on rat adrenal medulla - a morphological and ultrastructural study
(Sciendo, Warsaw, 2012)
Isolated rat adrenal medulla was analyzed by light and electron microscope after an acute (60 min) exposure to high ambient temperature (38A degrees C). Under these conditions there was a significant rise in plasma adrenaline ...
