Electronic cigarettes (e-cigarettes) are the most frequently used tobacco product among U.S. youths, and past 30-day e-cigarette use is more prevalent among high school students than among adults (1,2). E-cigarettes typically deliver nicotine, and the U.S. Surgeon General has concluded that nicotine exposure during adolescence can cause addiction and can harm the developing adolescent brain (2). Through authority granted by the Family Smoking Prevention and Tobacco Control Act, the Food and Drug Administration (FDA) prohibits e-cigarette sales to minors, free samples, and vending machine sales, except in adult-only facilities (3)...

Salbutamol, a selective β2-agonist, endangers the safety of animal products because of illegal use in food animals. In this study, an iTRAQ-based untargeted quantitative proteomic approach was applied to screen potential protein biomarkers in plasma of cattle before and after treatment with salbutamol for 21 days. A total of 62 plasma proteins were significantly affected by salbutamol treatment, which can be used as potential biomarkers to screen for the illegal use of salbutamol in beef cattle. Enzyme-linked immunosorbent assay measurements of five selected proteins demonstrated the reliability of iTRAQ-based proteomics in screening of candidate biomarkers among the plasma proteins...

Sodium nitrite (NaNO2) is widely used as a food additive and preservative in fish and meat products. We have evaluated the effect of a single acute oral dose of NaNO2 on oxidative stress parameters, antioxidant capacity and DNA in rat kidney. Male Wistar rats were divided into four groups and given single oral dose of NaNO2 at 20, 40, 60 and 75 mg/kg body weight; untreated rats served as the control group. All animals in NaNO2 -treated groups showed marked alterations in various parameters of oxidative stress as compared to the control group...

Each year in the United States, surgeons perform approximately 64 million surgical procedures, ranging from tooth extraction to open heart surgery. Yet, notwithstanding the frequency of surgical procedures and their often critical importance to patient health, no state or federal agency either approves the use of new surgical procedures or directly regulates existing procedures. The absence of surgical procedure regulation differs from the regulation of new pharmaceutical products, which can be introduced into interstate commerce only after the Food and Drug Administration (FDA) has reviewed "adequate and well-controlled [clinical] investigations" and concluded the data from those studies sufficiently establish the drug's safety and efficacy...

We demonstrate that capillary suspensions can be formed from hydrophilic calcium carbonate particles suspended in a polar continuous media and connected by capillary bridges formed of minute amounts of an immiscible secondary liquid phase. This was achieved in two different polar continuous phases, water and glycerol, and three different oils, oleic acid, isopropyl myristate, and peppermint oil as a secondary liquid phase. The capillary structuring of the suspension was made possible through local in situ hydrophobization of the calcium carbonate particles dispersed in the polar media by adding very small amounts of oleic acid to the secondary liquid phase...

Table olives are one of the most representatives and consumed fermented vegetables in Mediterranean countries. However, there is an evident lack of standardization of production processes and HACCP systems thus implying the need of establishing decision-making tools allowing their commercialization and shelf-life extension. The present work aims at developing a decision-making scoring system by means of a probabilistic assessment to standardize production process of Aloreña de Málaga table olives based on the identification of potential hazards or deficiencies in hygienic processes for the subsequent implementation of corrective measures...

The recent trends in microalgal cultures are focused on the biorefinery of the biomass components. Some of them are not completely valorised, for example starch. Since there is a wide market for starch products in food and non-food industries, the exploitation of microalgal starch fractions could improve the economic sustainability of microalgae production. In this perspective, the optimization of nitrogen and carbon source uptake for starch accumulation is a critical point for reducing the nitrogen requirement footprint and to increase CO2 capture...

Natural dietary products have been thoroughly studied for their effects of anti-adipogenesis to prevent and treat obesity for decades. Nevertheless, in the past few years appetite control for the treatment of obesity has attracted much attention as a new target. Homeostatic control of energy intake involves a complex system that conveys peripheral signals to the central nervous system where multiple signals are integrated and then provide feedback to regulate satiation. This perspective aims at elucidating the neuronal mechanisms of food intake and energy balance as well as providing an alternative pathway of controlling weight using natural dietary products...

The Food and Drug Administration, which now has regulatory authority over all tobacco products meeting the statutory definition, is tasked with communicating the risks of these products to the public through health warnings and public education. However, there have been no attempts to summarize what is known about non-cigarette tobacco product (NCTP) health messaging. We conducted a systematic review to examine the existing literature on health communication for NCTPs and identify key research gaps. A total of 45 unique studies were retrieved and coded, with the majority focused on messaging for smokeless tobacco (SLT, k = 32, 71...

The role of tobacco marketing in tobacco use, particularly among the vulnerable ethnic and socioeconomic sub-populations is a regulatory priority of the U.S. Food and Drug Administration. There currently exist both ethnic and socioeconomic disparities in the use of tobacco products. Monitoring such inequalities in exposure to tobacco marketing is essential to inform tobacco regulatory policy that may reduce known tobacco-related health disparities. We use data from the Population Assessment of Tobacco and Health (PATH) Wave 1 youth survey to examine (1) recalled exposure to and liking of tobacco marketing for cigarettes, non-large cigars, and e-cigarettes, (2) self-reported exposure to specific tobacco marketing tactics, namely coupons, sweepstakes, and free samples, and (3) self-reported impact of tobacco marketing and promotions on product use...

Changes in the isotopic composition (δ13 C and δ15 N) in biofilm, macro-invertebrates and resident salmonids were used to characterize temporal dynamics of marine derived nutrients (MDNs) incorporation between stream reaches with and without MDN inputs. Five Atlantic rivers were chosen to represent contrasting MDN subsidies: four rivers with considerable numbers of anadromous fishes; one river with little MDN input. Rainbow smelt Osmerus mordax, alewife Alosa pseudoharengus, sea lamprey Petromyzon marinus and Atlantic salmon Salmo salar, were the primary anadromous species for the sampled rivers...

Background: New biorefinery concepts are necessary to drive industrial use of lignocellulose biomass components. Xylan recovery before enzymatic hydrolysis of the glucan component is a way to add value to the hemicellulose fraction, which can be used in papermaking, pharmaceutical, and food industries. Hemicellulose removal can also facilitate subsequent cellulolytic glucan hydrolysis. Results: Sugarcane bagasse was pretreated with an alkaline-sulfite chemithermomechanical process to facilitate subsequent extraction of xylan by enzymatic or alkaline procedures...

Food reformulation has been suggested to be one of the strategies to reduce population added sugar (AS) intake. This study aims to investigate the untested assumption that a reduction in AS through reformulation will result in a reduction in population intakes of AS and energy. Plausible dietary data from 4,140 respondents of an Australian national nutrition survey were used. Dietary modelling was performed at AS reductions of 10%, 15%, and 25% using four strategies: simple removal of AS or replacement with non-nutritive sweeteners (NNS), and replacement of AS with NNS and either: polyols, 50% fibres or 50% maltodextrin...
