Artificial protein hydrogels made from a triblock protein (designated AC10A, where A is an acidic zipper domain and C10 comprises 10 repeats of the nonapeptide sequence exhibit normalized plateau storage moduli (G9‘/nkT) less than 0.13 at all concentrations, pH values, and ionic strengths examined. These gels are surprisingly soft due to loop formation at the expense of bridges between physical...

To aid in the characterization of the relationship of structure and function for human immunodeficiency virus type-1 reverse transcriptase (HIV-1 RT), this investigation utilized DNAs containing benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide (BPDE)-modified primers and templates as a probe of the architecture of this complex. BPDE lesions that differed in their stereochemistry around the C10 posit...

Differential scanning calorimetry, the temperature dependence of proton and deuteron lineshapes and spin-lattice relaxation times are reported for the isotopic species CH 3 NH 3 C10 4 , CD 3NH 3C104 and CH 3ND 3C104 of monomethylammonium Perchlorate. The data confirmed the existence of three different phase modifications in monomethylammonium Perchlorate and its selectively deuterated analogues...

BACKGROUND Rhamnolipids are the most extensively studied biosurfactants and has been successfully used in various areas from bioremediation to industrial fields. Rhamnolipids structural composition decide their physicochemical properties. Different physicochemical properties influence their application potential. Rhamnolipids can be produced at both aerobic conditions and anaerobic conditions b...

The objective of this study was to evaluate and compare the mucoadhesive properties ten commercially available polyacrylates including linear polyacrylic acid 100 450 kDa (PAA 450), with allyl pentaerythritol, sucrose divinyl glycol cross-linked PAAs AP, PAA AS/AP, DG) as well hydrophobically modified C10-30). Swelling behavior, rheological measurements polymer/mucus mixtures, rotating cylinder...

The micellar and surface behaviors of decylammonium chloride (DACl) in presence L-alanine hydrochloride decylester (L-ADE) dodecylester (L-ADDE) at various mole fractions were investigated by conductivity tension measurements. From the measurements, critical micelle concentration (CMC), degree counter-ion ionization (α) standard Gibbs energy micellization (ΔG°mic) for both pure binary mixtures....

UNLABELLED We established a new field clone of Plasmodium falciparum for use in controlled human malaria infections and vaccine studies to complement the current small portfolio of P. falciparum strains, primarily based on NF54. The Cambodian clone NF135.C10 consistently produced gametocytes and generated substantial numbers of sporozoites in Anopheles mosquitoes and diverged from NF54 parasite...
