At concentrations 4 times higher than the detection thresholds, these drugs have bitter as well as other unpleasant taste properties. Oral exposure to these drugs not only induces a taste from the drug itself but also alters taste perception of other compounds such as NaCl and sucrose. These results indicate that both hypogeusia and dysgeusia may be induced by psychotropic medications.

AU - Schiffman, S S T2 - Journal of Animal Science AB - The purpose of this paper is to examine the potential effects of livestock odors on the health and well-being of neighbors. Complaints of odor nuisance have become more frequent in communities surrounding areas with high concentrations of livestock. This increase in complaints from livestock odors parallels increased complaints of odor in general, including ammonia, diesel exhaust, beauty products, cleaners, and paints. Persons who report symptoms from odors generally find problems with many different types of odorous compounds. A review of recent studies suggests that the main complaints of health symptoms from odors are eye, nose, and throat irritation, headache, and drowsiness. Sensory irritation (pungency) can be produced by a broad range of odorous volatile organic compounds from trees, flowers, foods (pepper and ginger) as well as emissions from livestock operations. Odors can also potentially affect mood and memory. Further research is required to assess fully the health impact of odors in order to establish recommendations for air quality guidelines based on scientific data.

T2 - AIDS AB - To define the scope of taste and smell (chemosensory) complaints amongst HIV-infected persons in the study population; to evaluate the clinical factors associated with chemosensory complaints; and to determine the impact of chemosensory complaints on quality of life.Cross-sectional survey.Tertiary care university medical center clinic.A total of 207 HIV-infected patients.Chemosensory complaint score from taste and smell questionnaire and quality of life scores from the Medical Outcomes Study HIV Health Survey (MOS-HIV).A total of 144 patients (70%) reported chemosensory complaints, 91 (44%) reported both taste and smell complaints, 47 (23%) reported only taste complaints, and six (3%) reported only smell complaints. Many patients complained that drugs interfered with their sense of taste, or that medications tasted bad. Higher chemosensory complaint scores were associated with a greater number of medications taken, tobacco use, and hay fever. Patients with chemosensory complaints had significantly lower scores in all domains of the MOS-HIV than those without complaints. Quality of life as measured by the MOS-HIV was lower in patients with chemosensory complaints even after controlling for number of AIDS diagnoses, number of medications, CD4 cell count, and HIV-1 viral load.Chemosensory complaints were common in the patient population and were associated with a poor quality of life. Medications played an important role in chemosensory complaints. Measures to optimize taste and smell function may improve quality of life and medication adherence, and prevent complications such as inadequate oral intake, malnutrition, weight loss, and ultimately wasting.

AU - Schiffman, S.S. AU - Nagle, H.T. T2 - IEEE Transactions on Instrumentation and Measurement AB - Specific types of gas sensors are normally produced by adding different dopants to a common substrate. The advancement of technology has made the fabrication of many dopants and consequently various sensors possible. As a result, in each family of gas sensors, one can find tens of different sensors which are only slightly different in the spectrum of response to various volatile compounds. The wide variety of available gas sensors creates a selection problem for any specific application. Sensor selection/reduction becomes even more important when cost and technology limitations are issues of concern. Accordingly, a methodology by which one can tailor a sensor array to a specific need is highly desirable. In this paper, a novel method is introduced to address this task using data from an electronic nose that uses polymer gas sensors. This method has been delineated based on the geometry of eigenvectors in Karhunen-Loeve expansion. The methodology is general and therefore suitable for many other feature selection problems.

T2 - Food Reviews International AB - Abstract Worldwide, both the number and proportion of elderly persons is increasing dramatically. By 2025, it is predicted that there will be 1.121 billion persons over 60 years of age. Most of these elderly will have sensory losses including impairment of taste and smell perception. Taste and smell losses are serious because they can lead to inadequate dietary intake and impaired nutritional status. Dietary patterns in the elderly can be improved by sensory enhancement of foods using monosodium glutamate (MSG) and/or commercial flavors to compensate for chemosensory losses. Intensification of taste and odor with MSG and flavors can improve food acceptance, increase salivary flow and immunity, and reduce oral complaints.

The 8000 (203) possible kinds of amino acid residues in the middle of triplets consisting of consecutive residues were used for a precise analysis of helical segments in globular proteins. They correspond to the 8000 kinds of amino acid residues in a sequence of proteins. The 681 helices were built up from 8836 amino acid residues, which could be classified into 11 kinds of helix elements (a—k). Each of the amino acid residues in a sequence of helical segments could be allotted to one of 11 helix elements (a—k). Glycine residues in the proteins were used for its precise assignment as internal standards. The 11 kinds of helix elements could be statistically characterized with amino acid residues in the middle of triplets. Amino acid residues, observed as a specific helix element 3-times or more often in the total helical segments, were evaluated regarding their propensities for a specific helix element by using their inherent preference (IP)-values for the specific helix element, which had been defined in a previous paper. Amino acid residues found 13-times or more often in the data set are also listed to show their propensities for specific helix elements.

This GDH is composed of a single peptide with a molecular weight of 67kDa by SDS-PAGE and gel filtration chromatography. It cannot oxidize the C-1 hydroxy group of glucose which is commonly oxidized by other known GDHs or glucose oxidase. Since this enzyme reacts with 1,5AG, a novel enzymatic method for 1,5AG determination was developed utilizing the fluorescent electron mediator, AlamarBlue tm . A good linear correlation was observed from 2.5–200 μ m of 1,5AG, which covers both the healthy subjects' and the diabetics' range in blood.

The composition of these films was determined by Rutherford backscattering spectrometry and X-ray photoelectron spectroscopy (XPS). Raman spectroscopy and transmission electron microscopy studies showed typical features of DLC with a high fraction of sp3 bonded carbon in the doped films as well as in the undoped films. Wear resistance measurements made on the samples by means of the `crater grinding method' showed that DLC+2.75% Ti has the highest wear resistance, while that of pure DLC has the lowest amongst the samples. Careful analysis of the Raman data indicates a significant shift to shorter wavelength with the addition of metal, which means that the compressive stress in the DLC films has been reduced. We envisaged that the reduction in the compressive stress promotes the wear resistance of the coatings. The XPS studies showed evidence for the formation of Ti–C bonding in the Ti doped sample. Thus metal-doped DLC coatings are expected to improve the tribological properties and enhance the performance of components coated with metal-doped DLC.
