One hundred and three volatile compounds were detected by solid-phase microextraction followed by gas chromatography-mass spectrometry in 30 ripened Serrano dry-cured hams, submitted or not to high pressure processing (HPP) and afterwards held for 5months at 4°C. The effect of ham physicochemical parameters and HPP (600MPa for 6min) on volatile compounds was assessed. Physicochemical parameters...

Overwhelming evidence reveals that concentrations of dissolved organic carbon (DOC) have increased in streams which brings negative environmental impacts. DOC in stream flow is mainly originated from soil-water solutions of watershed. Wetlands prove to be the most sensitive areas as an important DOC reserve between terrestrial and fluvial biogeosystems. This reported study was focused on the di...

Geogenic arsenic (As) contamination of groundwater is a health threat to millions people worldwide, particularly in alluvial regions South and Southeast Asia. Mitigation measures are often hindered by high heterogeneities As concentrations, the cause(s) which elusive. Here we used comprehensive suite stable isotope analyses hydrogeochemical parameters shed light on mechanisms typical high-As Ho...

It has tremendous values for both drug discovery and basic research to develop a solid bioinformatical tool for guiding peptide reagent design. Based on the physical and chemical properties of amino acids, a new strategy for peptide reagent design, the so-called AABPD (amino acid based-peptide design), is proposed. The peptide samples in a training dataset are described by a series of HMLP (heu...

Objective: The aim this study was to compare the physicochemical characteristics of the honey of wild Melipona scutellaris with the standards determined by the technical regulations and honey quality of Ministry of Agriculture, Brazil. Methods: Honey of Melipona scutellaris was acquired from certified institution in Natal, RN, Brazil. The physicochemical analysis of honey was carried out so tha...

During the third trimester of human pregnancy the concentrations of deoxycorticosterone (DOC) in maternal plasma are 4-50 times those in nonpregnant women and men. It has been suggested that the increased amount of DOC in maternal plasma originates in the fetal compartment. We considered an alternate explanation for the high levels of DOC in plasma or near-term pregnant women, viz., that DOC ma...
