Candida albicans inactivation and cell membrane integrity damage by microwave irradiation
(2007-03-01)
In indicating the microwave irradiation for disinfecting dentures it is necessary to see how this procedure influences Candida albicans integrity and viability. The aim of this study was to evaluate the ability of microwaves ...
X-chromosome inactivation patterns in monozygotic twins and sib pairs discordant for nonsyndromic cleft lip and/or palate
(Wiley-Blackwell, 2007-12-15)
Nonsyndromic clefts of the lip and/or palate are common birth defects with a strong genetic component. Based on unequal gender ratios for clefting phenotypes, evidence for linkage to the X chromosome and the occurrence of ...
Inactivation of COX-2, HMLH1 and CDKN2A Gene by Promoter Methylation in Gastric Cancer: Relationship with Histological Subtype, Tumor Location and Helicobacter pylori Genotype
(Karger, 2011-01-01)
Objective: We aimed to evaluate the inactivation of COX-2, HMLH1 and CDKN2A by promoter methylation and its relationship with the infection by different Helicobacter pylori strains in gastric cancer. Methods: DNA extracted ...
CDKN2A promoter hypermethylation in astrocytomas is associated with age and sex
(2013-06-12)
CDKN2A promoter hypermethylation has been widely related to many cancers. In astrocytomas, although CDKN2A (p16INK4A protein) is often inactivated, there are still some controversial issues regarding the mechanism by which ...
Microsatellite Instability in Pediatric High Grade Glioma Is Associated with Genomic Profile and Differential Target Gene Inactivation
(Public Library Science, 2011-05-26)
High grade gliomas (HGG) are one of the leading causes of cancer-related deaths in children, and there is increasing evidence that pediatric HGG may harbor distinct molecular characteristics compared to adult tumors. We ...
Targeted Nucleotide Exchange in Bovine Myostatin Gene
(Taylor & Francis Inc, 2009-01-01)
The myostatin gene, known as Growth Differentiation Factor 8 (GDF8), located at chromosome 2 (BTA2) in cattle, is specifically expressed during embryo development and in the adult skeletal muscle. Molecular analysis of ...
Cellular responses in the Malpighian tubules of Scaptotrigona postica (Latreille, 1807) exposed to low doses of fipronil and boric acid
(2013-03-01)
Studies of sub-lethal effects of pesticide residues on stingless bees are scarce and morphological analysis of organs would add information to toxicological analysis in order to clarify the continuous exposure of Scaptotrigona ...
Protective effects of beta-glucan extracted from Agaricus brasiliensis against chemically induced DNA damage in human lymphocytes
(Springer, 2006-07-01)
beta-Glucans (BGs) are polysaccharides that are found in the cell walls of organisms such as bacteria, fungi, and some cereals. The objective of the present study was to investigate the genotoxic and antigenotoxic effects ...
Detection of Toxoplasma gondii in swine sausages
(2004-12-01)
In order to evaluate the importance of swine sausages in toxoplasmosis epidemiology, Toxoplasma gondii presence was investigated in 70 samples of the product commercialized in the city of Botucatu-SP. Samples were analyzed ...
Static electric fields interfere in the viability of cells exposed to ionising radiation
(Taylor & Francis Ltd, 2009-01-01)
Purpose: The interference of electric fields (EF) with biological processes is an issue of considerable interest. No studies have as yet been reported on the combined effect of EF plus ionising radiation. Here we report ...
