Three new glucosylceramides (GluCers) named malusides I-III (1-3) were isolated from apple (cultivars of Malus domestica) pomace (fruit material remaining after juice extraction). An unusual oxo/hydroxy group pattern within the sphingadienine (d18:2) type sphingoid base was observed. All compounds contained the same α-hydroxylated fatty acid (h16:0) and a β-D-glucose moiety. Their structures were assigned on the basis of one- and two-dimensional (1D and 2D) nuclear magnetic resonance (NMR) spectroscopic analyses and mass spectrometry (MS) measurements...

An emerging category of electronic cigarettes (ECIGs) are sub-Ohm devices (SODs) that operate at ten or more times the power of conventional ECIGs. Because carcinogenic volatile aldehyde (VAs) emissions increase sharply with power, SODs may expose users to greater VAs. In this study, we compared VA emissions from several SODs and found that across device, VAs and power were un-correlated unless power was normalized by coil surface area. VA emissions and liquid consumed were correlated highly. Analyzed in light of EU regulations limiting ECIG liquid nicotine concentration, these findings suggest potential regulatory levers and pitfalls for protecting public health...

Hydrated lime (Ca(OH)2) is a vernacular art and building material produced following slaking of CaO in water. If excess water is used, a slurry, called lime putty forms, which has been the preferred craftsman selection for formulating lime mortars since Roman times. A variety of natural additives were traditionally added to the lime putty to improve its quality. The mucilaginous juice extracted from nopal cladodes has been and still is used as additive incorporated in the slaking water for formulation of lime mortars and plasters both in ancient Mesoamerica as well as in the USA Southwest...

Oxidative stress and inflammation play a role in the physiopathology of insulin resistance, diabetes and cardiovascular disease. A single high-fat, high-carbohydrate (HFHC) meal induces an increase in inflammatory and oxidative stress markers in peripheral blood mononuclear cells (PBMC). Previous studies have shown that orange juice is able to prevent this response by inhibiting toll like receptors (TLR) expression and endotoxemia. Our goal was to study the proteome response in PBMC after the consumption of a HFHC meal consumed with water, orange juice or an isocaloric beverage (water with glucose)...

Active flight requires the ability to efficiently fuel bursts of costly locomotion while maximizing energy conservation during non-flying times. We took a multi-faceted approach to estimate how fruit-eating bats (Uroderma bilobatum) manage a high-energy lifestyle fueled primarily by fig juice. Miniaturized heart rate telemetry shows that they use a novel, cyclic, bradycardic state that reduces daily energetic expenditure by 10% and counteracts heart rates as high as 900 bpm during flight. Uroderma bilobatum support flight with some of the fastest metabolic incorporation rates and dynamic circulating cortisol in vertebrates...

Sauvignon blanc wine, balanced by herbaceous and tropical aromas, is fermented at low temperatures (10-15 °C). Anecdotal accounts from winemakers suggest that cold ferments produce and retain more 'fruity' aroma compounds; nonetheless, studies have not confirmed why low temperatures are optimal for Sauvignon blanc. Thirty-two aroma compounds were quantitated from two Marlborough Sauvignon blanc juices fermented at 12.5 °C and 25 °C, using Saccharomyces cerevisiae strains EC1118, L-1528, M2 and X5. Fourteen compounds were responsible for driving differences in aroma chemistry...

The consumption of sugars, particularly sugar-sweetened beverages (SSBs; beverages or drinks that contain added caloric sweeteners (i.e. sucrose, high-fructose corn syrup, fruit-juice concentrates), in European children and adolescents exceeds current recommendations. This is of concern because there is no nutritional requirement for free sugars, and infants have an innate preference for sweet taste, which may be modified and reinforced by pre- and postnatal exposures. Sugar containing beverages/free sugars increase the risk for overweight/obesity and dental caries, can result in poor nutrient supply and reduced dietary diversity and may be associated with increased risk of type 2 diabetes mellitus, cardiovascular risk, and other health effects...
