The polysaccharides beta-glucans occur as a principal component of the cellular walls. Some microorganisms, such as yeast and mushrooms, and also cereals such as oats and barley, are of economic interest because they contain large amounts of beta-glucans. These substances stimulate the immune system, modulating humoral and cellular immunity, and thereby have beneficial effect in fighting infect...

Gas-chromatography/mass-spectrometry and sensory descriptive analyses were applied to provide new data on volatile olfactory properties of Aglianico Primitivo (Zinfandel), Italian red wines growing interest. The relationships between sets investigated by multivariate statistical analyses: Principal Component Hierarchical Clustering Analyses (PCA, HCA). A total 35% the volatiles varied significa...

in this note, by considering the notions of the intuitionistic general l-fuzzy automaton and $(alpha, beta)$-language, we show that for any $(alpha, beta)$-language $mathcal{l}$, there exists a minimal intuitionistic general l-fuzzy automaton recognizing $mathcal{l}$.we prove that the minimal intuitionistic general l-fuzzy automaton is isomorphic with threshold $(alpha,beta)$ to any $(alpha, be...

Mouse embryos at day 9 of development were cultured for 24 to 42 h in 50% fetal calf serum and 50% Waymouth's medium containing 0.5 micrograms/ml insulin supplemented with various amounts of progesterone and estradiol-17-beta. Unmodified medium contained approximately 0.2% of the normal maternal blood levels for that stage of pregnancy. The addition of 1 X 10(-7)M progesterone to the medium bro...

This study was undertaken to define the incidence and concentration of uncharged nuclear estrogen receptors (RN) in human breast cancer. The concentrations of RN and cytoplasmic uncharged receptor were determined on sucrose gradients following a 4-hr incubation at 4 degrees with 1.6 nM 17 beta-[3H]estradiol in 139 tumor specimens from 137 patients. RN was extracted from washed nuclear pellets i...

In order to characterize possible disulfide-linked interactions between lens fiber cell membranes and crystallins, two-dimensional diagonal electrophoresis has been used in combination with Western blot analysis. When these blots were probed with monospecific antisera against alpha, beta and gamma crystallins, membrane from five individual normal lenses showed no disulfide-bonded components. Me...

Column (CC), thin-layer (TLC), high-performance liquid (HPLC) and ion-exchange chromatography (IEC), were used to investigate corotenoid and carotenoprotein complexes in Asellus aquaticus specimens from the Narew river. The following carotenoids were found: alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein, zeaxanthin, diadinoxanthin, mutatoxanthin, crustaxanthin, echinenone, hydroxyech...

in the present study, physicochemical, rheological and textural properties of beta-glucan (bg) extracted from four iranian hull-less barley lines (ehds4, ehds18, aleli, cam-b) were investigated. two different methods namely, hot water (hw) and acidic (a) were used for extraction of beta-glucan. results showed that the highest amount of beta-glucan belonged to ehds4.the purity of hw extracted be...

The surface glycocalyx of four dinoflagellate species were examined by fluorescent lectins. Cultures were synchronized by darkness for 82 h and changes in DNA content, cell density and surface sugars composition were monitored at 2 h intervals for 52 h in populations of four species: Alexandrium minutum, Gymnodinium catenatum, Prorocentrum micans and Gyrodinium impudicum. Lectin binding propert...

The goals of this study were to measure the relative levels of the alpha- and beta-isoforms of myosin heavy chain (MHC-alpha and MHC-beta, respectively) in multiple, specific regions of the adult rat heart and to determine whether age-dependent changes in isoform levels in different regions are uniform. Relative amounts of MHC-alpha and MHC-beta were determined in right and left atria and left ...
