(Charles University, 2010)BCL3 is a putative proto-oncogene deregulated in haematopoieitic and solid tumours. It has been suggested that its oncogenic effects could be mediated, at least in part, by inducing proliferation and inhibiting cell death. ...
-
(2010)Inositol 1,4,5-trisphosphate (IP3) receptors (IP3Rs) drive calcium signals involved in skeletal muscle excitation-transcription coupling and plasticity; IP3R subtype distribution and downstream events evoked by their ...
-
(2010)It describes the main features of SILAT as a multinational scientific and educational program that serves as a tool to analyze and solve the morphological medical terminology problems in Spanish and Portuguese speaking ...
-
(2010)The domestication of the rabbit (Oryctolagus cuniculus) has allowed the passage of a reproduction of the annual rate to a non-seasonal type, observing calving throughout the year. However, there are reproductive parameters ...
-
(Universidad de la Frontera, 2009)We examined the status of the first metacarpal bone whose shape, fetal and post-natal development correspond to those of the thumb proximal phalanx. Galen already described this, circa 170 CE. Our radiographic data confirm ...
-
(2010)Slow and persistent synaptic inhibition is mediated by metabotropic GABAB receptors (GABABRs). GABABRs are responsible for the modulation of neurotransmitter release from presynaptic terminals and for hyperpolarization at ...
-
(2010)The peritoneal equilibration test (PET) is the gold standard method for defining peritoneal membrane permeability and for prescribing peritoneal dialysis (PD) therapy on an individual basis. However, it is laborious, ...
-
(2010)N-3 polyunsaturated fatty acids (n-3 PUFA) affect inflammatory processes. This study evaluated the effects of dietary supplementation with fish oil on hepatic ischemia-reperfusion (IR) injury in the rat. Parameters of liver ...
-
(2010)The epithelial-mesenchymal transition (EMT) is considered a key step in tumor progression, where the invasive cancer cells change from epithelial to mesenchymal phenotype. During this process, a decrease or loss in adhesion ...

(American Society for Pharmacology and Experimental Therapy, 2010)The Erythrina alkaloids erysodine and dihydro-β-erythroidine (DHβE) are potent and selective competitive inhibitors of α4β2 nicotinic acetylcholine receptors (nAChRs), but little is known about the molecular determinants ...
-
(2010)The natural variation of sex-specific characters between populations can favor their behavioral isolation, eventually leading to the formation of new species. Marked variations for male courtship, mating and the production ...
-
(2010)Conflicts of interest are receiving increased attention in medical research, clinical practice and education. Criticism of, and penalties for, conflicts of interest have been insufficiently discussed and have been applied ...
-
(2010)Iron and copper ions, in their unbound form, may lead to the generation of reactive oxygen species via Haber-Weiss and/or Fenton reactions. In addition, it has been shown that copper ions can irreversibly and non-specifically ...
-
(2010)Prenatal undernutrition induces hypertension later in life, possibly by disturbing the hypothalamo-pituitary-adrenal axis through programming decreased expression of hypothalamic glucocorticoid receptors. We examined the ...
-
(2010)We previously reported that centrally-induced sympathetic activation in response to cold stress is associated with a polycystic ovarian condition in rats, and thyrotrophin-releasing hormone (TRH) released locally from the ...
-
(Lippincott Williams and Wilkins, 2010)Background: Empiric antifungal treatment has become standard of care in children with cancer and prolonged fever and febrile neutropenia (FN), with the downside that it leads to significant over treatment. We characterized ...
-
(Elsevier, 2010)Congenital Chagas’ disease, endemic in Latin America and also present with lower frequency in other countries, is associated with premature labor, miscarriage, and placentitis. The mechanism of tissue invasion and infection ...
