Phase behavior of aqueous amylopectin and beta-lactoglobulin system was studied using Fourier transform infrared spectroscopy. Polysaccharide-protein mixtures were prepared at different concentrations and left for equilibration; afterwards their spectra were recorded and correlated using Partial Least Square analysis. Tertiary phase diagrams were built for the system at different equilibration tim
Conjugate addition of the imino nitrogen of 2-aminobenzothiazoles 1 to the alkyne beta-carbon atom of acetylenic acids 2 followed by ring closure gives rise to novel 2H-pyrimido[2,1-b]-benzothiazol-2-ones in good yield.
Thin chromium cantilevers with sub-100 nm thickness have been characterized by an atomic force microscope operating in contact mode. A continuous determination of the local mechanical properties at all lengths was accomplished by applying force along the length of the cantilevers. The result show a decrease of the Young's modulus as the cantilevers get thinner.
In 2000, the stream cipher SNOW was proposed. A few attacks followed, indicating certain weaknesses in the design. In this paper we propose a new version of SNOW, called SNOW 2.0. The new version of the cipher does not only appear to be more secure, but its implementation is also a bit faster in software.
Prevention of incorporation of dUTP into DNA is essential for maintenance of the genetic information. Prompt and specific removal of dUTP from the nucleotide pool, as expedited by the ubiquitous enzyme dUTPase, is therefore required for full viability in most biological systems. Conserved structural features perpetuate specificity in choice of substrate, which is crucial as hydrolysis of the struc
The photoelectron satellite structure of rubidium and cesium has been investigated following the photoionization of an nd (n= 3,4) inner-shell electron. The intensity ratios of the nd(-1) ms monopole and nd(-1) m'p conjugated satellite lines have been measured at MAX-lab by using high-resolution electron spectroscopy. For rubidium, moreover, the energy dependence of the 3d(j)6s/3d(j)5s and 3d(j)5p
Recent epidemiological data on diseases caused by beta-hemolytic streptococci belonging to Lancefield group C and G ( GCS, GGS) underline that they are an emerging threat to human health. Among various virulence factors expressed by GCS and GGS isolates from human infections, M and M-like proteins are considered important because of their anti-phagocytic activity. In addition, protein G has been i
Constitutive activation of tyrosine kinases as a consequence of chromosomal translocations, forming fusion genes, plays an important role in the development of hematologic malignancies, in particular, myeloproliferative syndromes (MPSs). In this respect, the t(9;22)(q34;q11) that results in the BCR/ABL fusion gene in chronic myeloid leukemia is one of the best-studied examples. The fibroblast grow
In this study, we evaluated the possible use of lentiviral vectors in the treatment of neuropathic pain. We chose to administer GDNF-expressing vectors because of the known beneficial effect of this trophic factor in alleviation of neuropathic pain in adult rodents. Lentiviral vectors expressing either GDNF or control, green fluorescent protein or beta-galactosidase, were injected unilaterally int
Kinetics of chlorobenzene hydrodechlorination have been measured over Ni on SiO2, Al2O3, MgO, activated carbon and graphite. A stepwise variation of E-a is analysed using the selective energy transfer model where E-a is identified as the vibrational energy associated with an excitation of the chlorobenzene out-of-plane C-H bending mode. Variation of E-a with vibrational quantum number yields a vib
The translocation t(8;16) (p11;p13) was found as the sole deviation from the normal karyotype in three patients with acute monocytic leukaemia. The bone marrow morphology was strikingly similar in the two cases where smears were available for re-evaluation: the leukaemic cells showed signs of differentiation, and active erythrophagocytosis was a particularly conspicuous feature. We suggest that t(
BACKGROUND: Anisakis simplex, a fish parasite, causes allergic urticaria, angioedema and anaphylactic shock through an IgE-mediated hypersensitivity mechanism. Consensus on the dietary recommendations that should be given to allergic patients is lacking. Our objective was to evaluate the usefulness of different types of diets in preventing further reactions in patients allergic to A. simplex. METH
Background The impact of social participation, trust, and the miniaturization of community on daily and intermittent smoking was investigated. Methods The 2000 public health survey in Scania is a cross-sectional study. A total of 13,715 persons answered a postal questionnaire, which represents 59% of the random sample. A logistic regression model was used to investigate the association between
