BHT é um antioxidante usado como aditivo em alguns alimentos e em plásticos de embalagens, e sua presença em água mineral engarrafada é possível devido à migração do aditivo contido nas paredes do recipiente. Planejamento fatorial foi empregado para determinar os valores ótimos para os parâmetros operacionais principais na análise de hidroxitolueno butilado (BHT) em água engarrafada usando micr...
Bacteriohopanepolyols (BHPs) are a diverse class of bacterial lipids that hold promise as biomarkers specific microbes, microbial processes, and environmental conditions. BHPs have been characterized in variety terrestrial aquatic environments, but less is known about their distribution abundance extreme systems. In the present study, samples taken from water column upper sediments hyper-euxini...
Effects of feeding mice and rats with 2(3)-tert-butyl-4-hydroxyanisole (BHA) and 3,5-di-tert-butyl-4-hydroxytoluene (BHT), the two most commonly used food-additive phenolic antioxidants with known anticarcinogenic properties but with only minor differences in their chemical structures, have been compared to search for common effects between the two agents in two different rodent species and the...
A series of standardized laboratory tests [10 min sitting and supine, 9 min standing, dynamic; cycle ergometer (ERG) and isometric exercise; handgrip (HG)] were performed during intra-arterial blood pressure (BP) recording in 97 healthy unmedicated men, initially classified as normotensive (NT, n = 34), borderline hypertensive (BHT, n = 29) or mildly hypertensive (HT, n = 34) by repeated office...
Menopausal Hormone Therapy (MHT) use in Australia fell by 55% from 2001 to 2005, following the release of large-scale findings on its risks and benefits. Comprehensive national data, including information on overall prevalence of MHT use as well as information on duration of use in Australia have not been reported since the 2004-5 National Health Survey, when 11% of women aged 45+ years were es...
Natural antioxidants recently have gained popularity since synthetic ones have toxic and carcinogenic effects. In the present study, effect of temperature (120, 150 and 180°C) and cinnamaldehyde on oxidative stability of several oils (olive, hazelnut and palm oils) and fats (milkfat and butter) was examined. In order to compare the results with the synthetic antioxidant, butylated hydroxy tolue...
We previously reported that LXR ligand, T0901317, inhibited the growth of inoculated Lewis lung carcinoma in C57BL/6 mice by activating IFN-γ production. However, the effects of T0901317 on carcinogen-induced pulmonary carcinomas remain unknown. In this study, we initially conducted a statistical analysis on the data of human lung cancer samples extracted from the TCGA database, and determined ...
The Forkhead Box (Fox) family of transcription factors plays important roles in regulating expression of genes involved in cellular proliferation and differentiation. In a previous study, we showed that newborn foxf1(+/-) mice with diminished Foxf1 levels exhibited abnormal formation of pulmonary alveoli and capillaries and died postnatally. Interestingly, surviving newborn foxf1(+/-) mice exhi...
Phenolic compounds from Cressa cretica leaves were extracted using different solvents (water and ethanol 70%) during 3-24 h by immersion method and were determined according to the Folin-Ciocalteu method. The antioxidant activities of the extracts were investigated by 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging, ferric reduction activity potential and total antioxidant capacity ass...
BACKGROUND Antibodies to endothelial cells (aECs) and to cardiolipin (aCLs) are implicated in autoimmune diseases like systemic lupus erythematosus vasculitis. Beta2-Glycoprotein 1 (beta2GP1) is a cofactor for aCLs. The present study investigated the possible role of aECs, aCLs, and abeta2GP1 in borderline hypertension. METHODS AND RESULTS Seventy-three men with borderline hypertension (BHT) ...
