OBJECTIVE To determine the effect of supplementation with increasing doses of docosahexaenoic acid (DHA), as the only n-3 polyunsaturated fatty acid (PUFA), on low-density lipoprotein (LDL) redox status and oxidizability. METHODS Twelve healthy men aged 53-65 years ingested consecutive doses of DHA (200, 400, 800 and 1600 mg/day), each dose for two weeks. RESULTS The proportions of DHA incr...

Commonly used guidelines for the management of human immunodeficiency virus (HIV) infection (highly active antiretroviral therapy, HAART) include drug combinations such as tenofovir disoproxil fumarate (TDF) + lamivudine (3TC) and combivir [zidovudine (AZT) + 3TC] + efavirenz (EFV). These combinations may enhance the genotoxic effects induced by such drugs individually, since the therapy requir...

The aim of this study was to compare conventional photoplethysmography (PPG) in a finger with PPG using an integrating sphere (ISPPG) to enhance scattered light collection. Two representative wavelengths were used; 1160 nm, a window through the absorption spectra of water and alcohol, and 1600 nm around where water absorption is high and there is an absorption peak of blood glucose. Simultaneou...

An experiment was undertaken to develop a suitable seed production technique for Sperata aor in captivity. Naturally produced fry of aor was reared at different densities in nine nursery ponds 0.012 ha in size with an average depth of 0.8 m each. Three stocking densities tested, each of which was triplicated. Fry of aor stocked at 100,000/ha was designated as treatment-1 (T1), 150,000/ha as tre...

Los olmecas fueron una cultura prístina que creció al sur de México a partir del año 1600 a.C. El inconfundible estilo sus creaciones, se han hallado en gran parte territorio Mesoamérica, los ha identificado. Este estudio materiales pétreos usaron para esculpir obras artísticas, donde vemos la evolución un estético singular selección estratégica rocas. datos e hipótesis especialistas complement...

This study aimed to determine the guided bone regeneration (GBR) capacity of peri-implant bone defect treatment, either with only a hydroxyapatite bone graft or with a hydroxyapatite bone graft mixed with zoledronic acid (ZA) and employing polyethylene glycol (PEG) barrier membranes. In this study, four male New Zealand rabbits were used. First, the rabbits were randomly divided into two groups...
