There is a need to develop markers for early detection of organ failure in shock that can be noninvasively measured at point of care. We explore here the use of volatile organic compounds (VOCs) in expired air in a rat peritonitis shock model. Expired breath samples were collected into Tedlar gas bags and analyzed by standardized gas chromatography. The gas chromatograms were digitally analyzed...

In this study, volatile urinary components were collected using three different types of samples from patients suffering from urinary incontinence (UI): (1) urine (A); (2) urine + non-used pad (B); and (3) urine + used pad (C). In addition, urine + non-used pad (D) samples from non-patients were also collected as a reference. The collection of urinary volatiles was conducted with the aid of a g...

Standard protocols for sampling and measuring odor emissions from livestock buildings are needed to guide scientists, consultants, regulators, and policy-makers. A federally funded, multistate project has conducted field studies in six states to measure emissions of odor, coarse particulate matter (PM(10)), total suspended particulates, hydrogen sulfide, ammonia, and carbon dioxide from swine a...

Aspergillus fumigatus produces 2-pentylfuran (2-PF) when cultured on blood agar, nutrient agar and other media. As 2-PF is not known to be produced by mammalian metabolism we hypothesized that it is detectable in breath of patients colonized or infected with A. fumigatus. Breath was tested for 2-PF from normal subjects, those undergoing chemotherapy, and adults at risk of colonization or infect...

Abstract The removal of organic pollutants from ship emission was studied using two processes namely electron beam (EB) and hybrid EB with wet scrubbing process. A mobile accelerator unit used to treat 4915 Nm 3 /h flue gas emitted a tugboat in Riga Shipyard. volume m seawater containing 36.8 mM NaClO 2 oxidant as scrubber solution. Organic pollutants, mainly volatile (VOCs), were collected at ...

Rationale Selected ion flow tube mass spectrometry (SIFT-MS) is versatile, rapidly provides result output and determines a wide range of volatiles, making it suitable for biomedical applications. When direct sampling into the SIFT-MS instrument impractical, combining thermal desorption (TD) might offer solution as allows sample storage on sorbent tubes later analysis. This work compares off-lin...

and Implications Seventy-two finishing pigs were used to evaluate the effects of distillers dried grains with solubles (DDGS) on pig performance, manure characteristics, and odorous emissions. Three diets containing 0, 5, and 10% DDGS were fed during six 4-wk feeding periods. Week 1 served as a dietary adjustment period. Animals were housed in two feeding rooms (six pigs per room) with one trea...

Plastics are one of the most widely and abundant substances in today's society. Worldwide usage low-density polyethylene bags create pollution on land oceans, especially when they break down macro micro plastics. On all continents, governments try to establish solutions how fight plastic form shopping by banning their use, implant fees for replace with a more renewable material. Paper valid sol...
