such petroleum hydrocarbons as ethylene oligomer are among soil and water pollutants. physical and chemical methods employed in elimination of these pollutants, in addition to being inefficient, are damaging to the environment too. throughout the present research, powerful decomposer isolates, namely: lysinibacillus xylanilyticus (a bacterium isolate), and aspergillus niger (a fungal isolate) w...

We addressed the evolutionary trace of hetero-oligomer interfaces by comparing the structures of paralogous proteins; one of them is a monomer or homo-oligomer and the other is a hetero-oligomer. We found different trends in amino acid conservation pattern and hydrophobicity between homo-oligomer and hetero-oligomer. The degree of amino acid conservation in the interface of homo-oligomer has no...

Immunization with the B oligomer of pertussis toxin protected neonatal mice from a lethal respiratory challenge with Bordetella pertussis. All mice immunized with 8 micrograms of B oligomer survived aerosol challenge and had peripheral leukocyte counts and weight gains similar to those of mice immunized with pertussis toxoid before challenge and to those of control mice that were not challenged...

Objectives 1) Analyze the potential of amyloid beta (A)-oligomer concentrations in cerebrospinal fluid (CSF) to diagnose and predict progression to Alzheimer's disease (AD) in a large clinical study sample. 2) Monitor A-oligomer concentrations overtime , both in early and advanced stages of AD. 3) Examine the relation between A-oligomer levels in CSF and cognitive functioning. Methods 24 Non-de...

A study of the activity of deoxyribonucleotide-substituted analogs of the hammerhead domain of RNA catalysis has led to the design of a 14mer oligomer composed entirely of deoxyribonucleotides that promotes the cleavage of an RNA substrate. Characterization of this reaction with sequence variants and mixed DNA/RNA oligomers shows that, although the all-deoxyribonucleotide oligomer is less effic...

• The molecular chaperone CCT has functions in addition to protein folding. oncogenic transcription factor STAT3 binds oligomer. is not an obligate folding substrate of CCT. Reduction levels leads enhanced phosphorylation MCF7 cells. Sequestration by may provide a means regulate phosphorylation. Chaperonin Containing Tailless complex polypeptide 1 (CCT) essential required for the abundant prote...

in this research we used heavy propylene tetramer (hpt) and a1c13 —bf3 (lewis acids) ascatalyst and ethanol, n-propanol and n-butanol as co-catalyst. using lewis acids as catalyst, thehpts form molecules with higher molecular weight. since the raw materials of the reaction are byproducts of other reactions, are not pure and contain various compounds with different m.w andalso different chemical...
