Streptomyces sp JS520 produces exceptionally high quantities of undecylprodigiosin with antibacterial, antioxidative, and UV-protective properties
(Springer, New York, 2012)
A Gram-positive, red-pigment-producing bacterial strain, designated JS520 was isolated from the pristine sediment from the cave on mountain Miroc in Serbia. Strain was confirmed to belong to Streptomyces genus based on ...
The synthesis of 2,5-bis(4-amidinophenyl)thiophene derivatives providing submicromolar-range inhibition of the botulinum neurotoxin serotype A metalloprotease
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2012)
Botulinum neurotoxins (BoNTs), composed of a family of seven serotypes (categorized A-G), are the deadliest of known biological toxins. The activity of the metalloprotease, light chain (LC) component of the toxins is ...
Far infrared study of local impurity modes of Boron-doped PbTe
(Springer, New York, 2012)
PbTe single crystals, doped with B, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and room temperature. The experimental spectra were numerically analyzed, ...
Printed Planar 8 x 8 Array Antenna With Circular Polarization for Millimeter-Wave Application
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2012)
A new type of printed millimeter planar antenna with circular polarization for 60-GHz range is proposed. Radiation elements with two open tape rings are arranged in a two-dimensional 8 x 8 antenna array. Feeding is synphase ...
A novel C,D-spirolactone analogue of paclitaxel: autophagy instead of apoptosis as a previously unknown mechanism of cytotoxic action for taxoids
(Royal Soc Chemistry, Cambridge, 2012)
The design, synthesis and biological evaluation of a novel C, D-spirolactone analogue of paclitaxel is described. This is the first paclitaxel analogue without an oxetane D-ring that shows a significant cytotoxic effect ...
Maskless convex corner compensation technique on a (100) silicon substrate in a 25 wt% TMAH water solution
(Iop Publishing Ltd, Bristol, 2012)
A maskless convex corner compensation technique in a 25 wt% TMAH water solution at the temperature of 80 degrees C is presented and analyzed. The maskless convex corner compensation technique is defined as a combination ...
Extension of the AMBER force field to cyclic alpha,alpha dialkylated peptides
(Royal Soc Chemistry, Cambridge, 2012)
The popular biomolecular AMBER (ff99SB) force field (FF) has been extended with new parameters for the simulations of peptides containing alpha, alpha dialkylated residues with cyclic side chains. Together with the recent ...
Serum Polyamines in Patients With Non-Hodgkin's Lymphoma
(Elsevier Sci Ltd, Oxford, 2012)
Analysis of dynamic mechanical, thermal and surface properties of poly(urethane-ester-siloxane) networks based on hyperbranched polyester
(Elsevier, 2012)
Six polyurethane networks were synthesized from Boltorn (R) hyperbranched polyester of the second pseudo generation, alpha,omega-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO) and ...
Phase relations in bi - rich part of the bi-ga-ni system
(Technical Faculty, Bor, 2012)
The results of phase relations investigation in bismuth-rich part of ternary Bi-Ga-Ni system are presented in this paper. Two sections with constant bismuth content equal to 80 and 90 at% were investigated experimentally ...
