We sequenced the complete genome of the isolate Pseudomonas sp. CCOS 191. This strain is able to dissolve phosphate minerals and form cyanide. The genome sequence is used to establish the phylogenetic relationship of this species.

A 16-residue peptide [(Ala-Glu-Ala-Glu-Ala-Lys-Ala-Lys)2] has a characteristic beta-sheet circular dichroism spectrum in water. Upon the addition of salt, the peptide spontaneously assembles to form a macroscopic membrane. The membrane does not dissolve in heat or in acidic or alkaline solutions, nor does it dissolve upon addition of guanidine hydrochloride, SDS/urea, or a variety of proteolyti...

In this work interdigitated heterojunction photovoltaic devices were manufactured. A donor layer of P3HT nanopillars was fabricated by soft nanoimprinting using nanoporous anodic alumina templates. Subsequently, the PC70BM acceptor layer was deposited by spin coating on top of the P3HT nanopillars using a solvent that would not dissolve any of the previous material. Anisole solvent was used bec...

The potential of MRI-guided focused ultrasound (MRgFUS) combined with the thrombolytic drug recombinant tissue plasminogen activator (rt-PA), to dissolve clots in the carotid of a New Zealand rabbit in vivo is evaluated. A spherically-focused transducers of 5 cm diameter; focusing at 10 cm and operating at 1 MHz was used. A pulsed ultrasound protocol was used that maintains a tissue temperature...

It is not understood how Hsp104, a hexameric AAA+ ATPase from yeast, disaggregates diverse structures, including stress-induced aggregates, prions, and α-synuclein conformers connected to Parkinson disease. Here, we establish that Hsp104 hexamers adapt different mechanisms of intersubunit collaboration to disaggregate stress-induced aggregates versus amyloid. To resolve disordered aggregates, H...

Electrophoresis of constituent proteins in polyacrylamide gels has become a useful aid in the identification of mycoplasmas. Razin & Rottem (1967) showed that mycoplasma proteins dissolved in phenol and acetic acid give reproducible, species-specific electrophoretic patterns when separated in the presence of acetic acid and urea. We encountered difficulties when using this technique. Mycoplasma...

This study evaluated the influence of the addition of cetrimide and polypropylene glycol to sodium hypochlorite (NaOCl) on its capacity to dissolve pulp tissue. Bovine pulp fragments with standardized weight and volume were immersed for 5, 15 and 30 min in 2 mL of NaOCl and Hypoclean (NaOCl added with cetrimide and polypropylene glycol) solutions at 5.25%, 2.5%, 1%, 0.5% and 0.25% and afterward...

Magnetically-actuated soft robots have potential for medical application but require further innovation on functionality and biocompatibility. In this letter, a multi-segmented snake-inspired robot with dissolvable biocompatible segments is designed. The actuation response under external magnetic field investigated through simulations experiments. A dissolve-controllable mixture of gelatin, gly...

The present study had its origin in certain experiments carried on in our laboratory to determine the possible influence of metals on bacterial growth. It was observed that members of the Escherichia-Aerobacter group when cultivated in an unbuffered glucose broth containing iron filings produced sufficient acid to dissolve some of the iron. The dissolved iron was detected by means of the potass...
