To explore the relationships between transcription, messenger RNA (mRNA) processing, and nuclear structure, ribonucleoprotein particles containing heterogeneous nuclear RNA (hnRNP) have been purified from globin-producing mouse Friend erythroleukemia cells. These nuclear hnRNP particles sediment at 50S-200S and contain, in addition to high molecular weight hnRNA, a specific set of nuclear prote...
We used the low molecular weight form of apolipoprotein B (B-48) as a marker for the identification of remnant particles formed from chylomicrons in the plasma of patients with familial dysbetalipoproteinemia. In the serum of patients fasted 14 hours, the d less than 1.006 g/cm3 lipoproteins of prebeta mobility, separated by starch block electrophoresis, contained only the primary hepatogenous ...
We investigated the strange hadrons transverse momentum (${p}_{T}$) spectra in Au-Au collision at $\sqrt{{s}_{NN}}=54.4\text{ }\text{ }\mathrm{GeV}$ framework of modified Hagedorn function with embedded flow. It is found that model can describe particle well. extracted kinetic freeze-out temperature ${T}_{0}$, flow velocity ${\ensuremath{\beta}}_{T}$, volume $V$, mean $⟨{p}_{T}⟩$, entropy param...
The results of research on the application method measurement gross alpha-, beta-activity in water using liquid scintillation counter (LSC) Quantulus 1220 are presented. Basic procedures preparation and spectrometric aqueous samples were studied performed. detection efficiency beta-particles depending quenching optimum beta-radiation separation parameter for used determined. Testing validation ...
Fungi grown in pure cultures produce DNA- or RNA-containing particles smaller than spore size (<1.5 microm). High exposures to fungi and bacteria are observed at biofuel plants. Airborne cultivable bacteria are often described to be present in clusters or associated with larger particles with an aerodynamic diameter (d(ae)) of 2-8 microm. In this study, we investigate whether airborne fungal co...
Extracts from nodavirus-infected Drosophila cells contained detergent-labile 140S "young" particles much richer than mature virions in their content of protein alpha, a precursor of coat proteins beta and gamma. Incorporation studies in infected cells showed that most newly synthesized alpha protein was assembled into young particles within a few minutes. Incubation of the particles, either in ...
In this paper, covalent immobilization of beta amylase enzyme on the surface of modified magnetic nano particles (ZnFe2O4@SiO2-NH2) is reported. For doing so, at first, the magnetic nanoparticles of ZnFe2O4 were synthesized by chemical co-precipitation method and then tetraethyl orthosilicate (TEOS) and 3-aminopropyltriethoxy sil...
ti-6al-4v titanium alloy has great application in medicine and military industries due to its capabilities, namely high strength to weight ratio and corrosion resistance. in the current research, the effect of aging treatment on microstructure and wear behavior of ti-6al-4v titanium alloy was investigated. pin on disk wear test was applied to assess the wear behavior. specimens were first solut...
