We report the first results from a new instrument capable of acquiring infrared spectra of mobility-selected ions. This demonstration involves using ion mobility to first separate the protonated peptide Gly-Pro-Gly-Gly (GPGG) into two conformational families with collisional cross-sections of 93.8 and 96.8 Å(2). After separation, each family is independently analyzed by acquiring the infrared p...

glycine allele at codon 16 has previously been associated with the increase in asthma severity, bronchial hyperresponsiveness and also the increase in inhaled corticosteroid dependence. this study was designed to evaluate the genetic alleles in mild asthma.thirty-four patients with diagnosis of mild asthma (fev1 ≥ 80%, positive methacholine test) and body mass index (bmi ≤ 30 kg/m2) were includ...

The chemical valorization/repurposing of biomass-derived chemicals contributes to a biobased economy. Furfural (Fur) is recognized platform produced from renewable lignocellulosic biomass, and furfuryl alcohol (FA) its most important application. aromatic aldehydes Fur benzaldehyde (Bza) are commonly found in the slate compounds via biomass pyrolysis. On other hand, glycerol (Gly) by-product in...

To clarify the role of an amino acid residue in pH-dependent efflux process Chinese hamster ovary (CHO) cells expressing human oligopeptide transporter hPEPT1 (CHO/hPEPT1), we determined effect extracellular pH on hPEPT1-mediated process. The glycylsarcosine (Gly-Sar), a typical substrate for hPEPT1, was using infinite dilution method after were preloaded with [3H]-Gly-Sar. [3H]-Gly-Sar stimula...

The high population growth worldwide causes a demand for food with an increase in the use of different agrochemicals, pesticides and herbicides being primary pollutants anthropogenic origin environment. One critical aims ecotoxicology is evaluation toxic effects mixtures chemical substances that can have additive, synergistics or antagonistics ecosystems. For this reason, research were to: 1) e...
