[Ab] Resumo:Although less widespread than twenty years ago, inhalant abuse remains an on-going problem, whose incidence among U.S. teenagers and young adults ranges from 10 to 15%. Death due to the inhalation of vapor from halogenated hydrocarbons is a well-known phenomenon, yet few cases of fatal butane-gas poisoning have been described. Many cases of volatile substance abuse in prison populations have been reported: drug-addicted inmates often resort to this alternative practice when unable to get their habitual drugs of abuse. A similar pattern occurs especially among adolescents. The study herein described was conducted including all cases of fatal acute intoxication of butane gas examined from 2007 to 2015 at the Institute of Legal Medicine and Forensic Sciences of the University of Genoa. In the absence of overt and specific macroscopic and histological findings indicating cause and pathological mechanism of death, we aimed to assess whether recent cardiac lesions were detectable by way of immunohistochemical (IHC) analysis. Specifically, fibronectin and troponin C expression in myocardial tissues were investigated in deaths from acute butane-gas poisoning so as to better define the underlying pathological mechanisms. IHC findings were indicative of hypoxic cardiac damage. In all cases, positivity to fibronectin and mildly to moderately reduced troponin C expression in cardiac muscle cells were immunohistochemically ascertained.

[Ab] Resumo:INTRODUCTION: While generally reducing morbidity and mortality, electrical weapons have risks associated with their usage, including eye injuries and falls. With the presence of explosive fumes or fuels there also exists the possibility of burn injury. METHODS: We searched for cases of fatal and non-fatal major burns with TASER electrical weapon usage where there was a possibility that the weapon ignited the explosion. RESULTS: We confirmed 6 cases of fatal burn injury and 4 cases of major non-fatal burns out of 3.17 million field uses. The mean age was 35.5 ± 9.7 years which is consistent with the typical arrest-related death. Moderate, minor, and noninjurious fires - typically due to a cigarette lighters in a pocket, petrol, recreational inhalants, or body spray were also noted. CONCLUSIONS: The use of electrical weapons presents a small but real risk of death from fatal burn injury. It also presents a small risk of major non-fatal burn injury. The ignition of petrol fumes dominates these cases of major fatal and nonfatal burns.

[Ab] Resumo:We specially carried out the subcritical butane extraction to separate abamectin from tea leaves. Four parameters, such as extraction temperature, extraction time, number of extraction cycles, and solid-liquid ratio were studied and optimized through the response surface methodology with design matrix developed by Box-Behnken. Seventeen experiments with three various factors and three variable levels were employed to investigate the effect of these parameters on the extraction of abamectin. Besides, catechins, theanine, caffeine, and aroma components were determined by both high-performance liquid chromatography and gas chromatography-mass spectrometry to evaluate the tea quality before and after the extraction. The results showed that the extraction temperature was the uppermost parameter compared with others. The optimal extraction conditions selected as follows: extraction temperature, 42°C; number of extraction cycles and extraction time, 1 and 30 min, respectively; and solid-liquid ratio, 1:10. Based on the above study, the separation efficiency of abamectin was up to 93.95%. It is notable that there has a quite low loss rate, including the negligible damage of aroma components, the bits reduce of catechins within the range of 0.7%-13.1%, and a handful lessen of caffeine and theanine of 1.81% and 2.6%, respectively. The proposed method suggested subcritical butane possesses solubility for lipid-soluble pesticides, and since most of the pesticides are attached to the surfaces of tea, thus the as-applied method was successfully effective to separate abamectin because of the so practical and promising method.

[Ab] Resumo:A simple, fast, sensitive, and robust gas chromatography-mass spectrometry (GC-MS) method for the simultaneous determination of propane-1,2-diol, butane-2,3-diol, and propane-1,3-diol in cheese and bacterial cultures was developed. Target analytes were extracted and transformed into their phenylboronic esters prior to analysis. The method showed good sensitivity, without carryover between the samples. The detection limits for propane-1,2-diol, butane-2,3-diol, and propane-1,3-diol in cheese samples were 0.26, 0.02, and 0.11mgkg , respectively, and for bacterial culture samples were 1.32, 0.09, and 0.54mgkg , respectively. The Horwitz ratio showed good precision for all analytes (<0.45). The calibrated range in cheese for all analytes was very broad, from 0 to 1000mgkg , and in bacterial cultures was from 0 to 5000mgkg with R >0.9991. The results confirm excellent applicability of the proposed method for the determination of the target metabolites in cheese and bacterial culture samples.

[Ab] Resumo:As a natural and healthy beverage, tea is widely enjoyed; however, the pesticide residues in tea leaves affect the quality and food safety. To develop a highly selective and efficient method for the facile removal of pesticide residues, the subcritical butane extraction (SBE) technique was employed, and three variables involving temperature, time and extraction cycles were studied. The optimum SBE conditions were found to be as follows: extraction temperature 45 °C, extraction time 30 min, number of extraction cycles 1, and in such a condition that the extraction efficiency reached as high as 92%. Further, the catechins, theanine, caffeine and aroma components, which determine the quality of the tea, fluctuated after SBE treatment. Compared with the uncrushed leaves, pesticide residues can more easily be removed from crushed leaves, and the practical extraction efficiency was 97%. These results indicate that SBE is a useful method to efficiently remove the bifenthrin, and as appearance is not relevant in the production process, tea leaves should first be crushed and then extracted in order that residual pesticides are thoroughly removed.

[Ti] Título:Maleimide scavenging enhances determination of protein S-palmitoylation state in acyl-exchange methods.

[Ab] Resumo:S-palmitoylation (S-acylation) is emerging as an important dynamic post-translational modification of cysteine residues within proteins. Current assays for protein S-palmitoylation involve either in vivo labeling or chemical cleavage of S-palmitoyl groups to reveal a free cysteine sulfhydryl that can be subsequently labeled with an affinity handle (acyl-exchange). Assays for protein S-palmitoylation using acyl-exchange chemistry therefore require blocking of non-S-palmitoylated cysteines, typically using N-ethylmaleimide (NEM), to prevent non-specific detection. This in turn necessitates multiple precipitation-based clean-up steps to remove reagents between stages, often leading to variable sample loss, reduced signal, or protein aggregation. These combine to reduce the sensitivity, reliability, and accuracy of these assays, which also require a substantial amount of time to perform. By substituting these precipitation steps with chemical scavenging of NEM by 2,3-dimethyl-1,3-butadiene in an aqueous Diels-Alder 4+2 cyclo-addition reaction, it is possible to greatly improve sensitivity and accuracy while reducing the hands-on time and overall time required for the assay.

[La] Idioma:eng
[Ab] Resumo:In this study, the subcritical butane extraction process of fenugreek seed oil was optimized using response surface methodology with a Box-Behnken design. The optimum conditions for extracted oil from fenugreek seed was as follows: extraction temperature of 43.24 °C , extraction time of 32.80 min, and particle size of 0.26 mm. No significant differences were found between the experimental and predicted values. The physical and chemical properties of the oil showed that the oil could be used as edible oil. Fatty acid composition of oils obtained by subcritical butane under the optimum conditions and by accelerated solvent extraction showed negligible difference. The oils were rich in linoleic acid (42.71%-42.80%), linolenic acid (26.03%-26.15%), and oleic acid (14.24%-14.40%). The results revealed that the proposed method was feasible, and this essay shows the way to exploit fenugreek seeds by subcritical butane extraction under the scope of edible oils.

[Ab] Resumo:In patients with Alzheimer's disease (AD) and in a triple transgenic (3xTgAD) mouse model of AD low glucose metabolism in the brain precedes loss of memory and cognitive decline. The metabolism of ketones in the brain by-passes glycolysis and therefore may correct several deficiencies that are associated with glucose hypometabolism. A dietary supplement composed of an ester of D-ß-hydroxybutyrate and R-1,3 butane diol referred to as ketone ester (KE) was incorporated into a rodent diet and fed to 3xTgAD mice for 8 months. At 16.5 months of age animals were killed and brains dissected. Analyses were carried out on the hippocampus and frontal cortex for glycolytic and TCA (Tricarboxylic Acid) cycle intermediates, amino acids, oxidized lipids and proteins, and enzymes. There were higher concentrations of d-ß-hydroxybutyrate in the hippocampus of KE-fed mice where there were also higher concentrations of TCA cycle and glycolytic intermediates and the energy-linked biomarker, N-acetyl aspartate compared to controls. In the hippocampi of control-fed animals the free mitochondrial [NAD ]/[NADH] ratio were highly oxidized, whereas, in KE-fed animals the mitochondria were reduced. Also, the levels of oxidized protein and lipids were lower and the energy of ATP hydrolysis was greater compared to controls. 3xTgAD mice maintained on a KE-supplemented diet had higher concentrations of glycolytic and TCA cycle metabolites, a more reduced mitochondrial redox potential, and lower amounts of oxidized lipids and proteins in their hippocampi compared to controls. The KE offers a potential therapy to counter fundamental metabolic deficits common to patients and transgenic models. Read the Editorial Highlight for this article on page 162.

[Ab] Resumo:Voluntary inhalation/abuse of volatile substances is an important public health problem which especially affects adolescent and young populations worldwide and may be encountered in all socioeconomic and cultural levels. Lighter gas abuse-related death is still an important health problem in Turkey. In this study, 25,265 case files and final reports submitted to the Institute of Forensic Medicine of the First Specialization Board between January 2011 and December 2015 were evaluated retrospectively. In 56 of these cases, lighter gas inhalation (n-butane, propane, isobutane) was recorded as the cause of death. All subjects were male with a mean age of 16.8years. According to eyewitness and crime scene investigation reports, in 48 (85.7%) of the cases, a lighter refill container was found at the scene. It was determined that 21.4% of the cases used a plastic bag to increase the effects of lighter gas and 76.8% inhaled the lighter gas via their mouth and nose. The toxicological analysis of the samples taken while hospitalized showed no lighter refill components (n-butane, propane, isobutane) in 66% of the cases, n-butane in 32.1% of the cases, and n-butane+propane+isobutane in 1.9% of the cases. The importance of lighter gas inhalation-related deaths in Turkey has been increasing. Strict measures against the abuse of these very dangerous substances should be undertaken by the mutual efforts of medical specialists and legislators.

[Ab] Resumo:Carbon nanotubes (CNTs) were used in oxidative dehydrogenation (ODH) reactions. Quinone groups on the CNT surface were identified as active sites for the dehydrogenation pathway. Liquid-phase oxidation with HNO is one way to generate various oxygen functionalities on the CNT surface but it produces a large amount of acid waste, limiting its industrial application. Here, a facile and efficient oxidative method to prepare highly selective CNT catalysts for ODH of n-butane is reported. Magnesium nitrate salts as precursors were used to produce defect-rich CNTs through solid-phase oxidation. Skeleton defects induced on the CNT surface resulted in the selective formation of quinone groups active for the selective dehydrogenation. The as-prepared catalyst exhibited a considerable selectivity (58 %) to C olefins, which is superior to that of CNTs oxidized with liquid HNO . Through the introduction of MgO nanoparticles on the CNT surface, the desorption of alkenes can be accelerated dramatically, thus enhancing the selectivity. This study provides an attractive way to develop new nanocarbon catalysts.
