Several cooked meats such as beef (fried, coated-fried), pork (fried, coated-fried), and chicken (fried, griddled, coated-fried, roasted) were analyzed for the heterocyclic amine 2-amino-l-methyl-6-(4-hydroxyphenyl)imidazo[4,5-b]pyridine (4'-OH-PhIP) not commonly determined in food and 2-amino-1 -methyl-6-phenylimidazo[4,5-b]pyridine (PhIP). The highest content of 4'-OH-PhIP was found in fried and
Recent experiments and numerical studies have showed that piston geometry has a significant effect on the homogeneous charge compression ignition (HCCI) process. There are two effects generated by the combustor geometry: the geometry affects the flow/turbulence in the cylinder; the geometry also affects the temperature stratification. The temperature stratification is more directly responsible for
The emergence of levodopa (l-DOPA)-induced dyskinesia and motor fluctuations represents a major clinical problem in Parkinson's disease (PD). While it has been suggested that the daily dose of l-DOPA can play a critical role, the mechanisms linking l-DOPA dosage to the occurrence of motor complications have not yet been explored. Using an experimental model of PD we have recently demonstrated that
1. It has recently been suggested that not only nutrients but also presence of a competitor can influence competitive ability in plants, for example, by strategic changes in allocation to roots (a 'tragedy of the commons' effect). Such strategic changes might occur also in pollen, because this has potential to increase siring success during pollen competition in the pistil. 2. I tested the new hyp
Catalysts of the nominal composition Sb0.9V0.9-xTixOy, 0.0 less than or equal to x less than or equal to 0.9, were prepared and characterized with X-ray diffraction, Fourier transform-Raman spectra, diffuse reflectance infrared Fourier transform spectra, transmission electron microscopy, electron diffraction, and X-ray microanalysis. The catalysts were used for the ammoxidation of propane to give
This study aims at the investigation of the possibilities to use immobilised lipase from Candida antarctica in supercritical fluid extraction (SFE) of borage (Borago officinalis L.) seed oil. The first series of experiments was performed to measure the extract yields obtained with pure CO2 and with the added entrainer (ethanol). The yield increased more than twice after increasing the extraction p
For a short-lived organism, such as a freshwater zooplankter, the ways of coping with years of local recruitment failure are either to disperse between habitats and recolonise or to disperse in time through diapause. Diapause is common among freshwater zooplankton and is generally seen as a way to escape periods of harsh environmental conditions. The egg-bank or pool of diapausing copepodites in l
Nitrogen (N) is often considered to be the major factor limiting tree growth in northern forest ecosystems. An increased N availability, however, increases the demand for other nutrients such as base cations and phosphorous (P) which in turn may change which nutrient is the limiting factor. If P or base cations become limiting, N will start to leach which means a risk of increased eutrophication o
MAX-lab has introduced a local perturbation to the electron orbit of the MAX II storage ring, providing users at the SX700 monochromator beam line, D1011, with elliptically polarised soft X-rays. This is achieved by using corrector magnets to send the electron orbit on an ascending or descending trajectory through the dipole magnet source. This simple "bump" approach has many advantages over and a
The present immunohistochemical investigation reveals that difucosylated carbohydrate antigens (DFCA) are extensively expressed in rectal and rectosigmoid carcinomas while normal mucosa and hyperplastic polyps are mainly negative. The adenomas showed intermediate staining patterns where adenomas with villous structures and moderate-severe dysplasia resembled of carcinomas. CEA was more extensively
A gas chromatographic method was developed to quantify the phytotoxin prehelminthosporol, which is a sesquiterpene metabolite of the plant pathogen Bipolaris sorokiniana. The toxin was extracted from mycelium or culture filtrates, pre-cleaned using solid phase extraction, and analyzed by gas chromatography as a trimethylsilyl-derivative. The detection limit of the method was 5 ng mul(-)1 (signal t
Our knowledge of muscle function in chronic neurological disorders, the effects of exercise, and how the effects might translate into improvements in activities of daily living is very limited. By building a bridge between basic muscle physiology and clinical rehabilitation, our knowledge of the pathophysiological mechanisms underlying muscle dysfunction in people with chronic neurological disorde
Aerosols affect precipitation by modifying cloud properties such as cloud droplet number concentration (CDNQ. Aerosol effects on CDNC depend on aerosol properties such as number concentration, size spectrum, and chemical composition. This study focuses on the effects of aerosol chemical composition on CDNC and, thereby, precipitation in a mesoscale cloud ensemble (MCE) driven by deep convective cl
Enteral exposure of suckling rats to phytohaemagglutinin (PHA) has been shown to induce growth and precocious functional maturation of the gastrointestinal tract. The aim of the present study was to explore the mechanism of this action. Suckling rats, 14 d old, were fed a single dose of PHA (0.05 mg/g body weight) or saline. The binding of PHA to the gut epithelium and its effect on the morphology
The purpose of the present study was threefold: (a) to replicate the finding by MacLeod and Rutherford (1992) that low trait-anxious individuals, in contrast to high trait-anxious individuals, show a selective attention away from subliminally presented threat words at elevated levels of stress; (b) to test the hypothesis that this effect is due to individuals with repressive coping-style rather th
