A study of the ecology Vibrio parahaemolyticus and related vibrios in Rhode River area Chesapeake Bay was carried out over period December 1970 through August 1971. The incidence V. found to be correlated with water temperature. could not detected column during winter months, although they were present sediment. From late spring early summer, when temperatures 14 ± 1 C, over-wintering sediment released from bottom communities attached zooplankton, proliferating as temperature rose. number on...
A new species of Pseudomonas was isolated that produced copious amounts an exocellular heteropolysaccharide (PS-60) after incubation for 3 days at 30°C in media containing 3% glucose as a carbon source. The polysaccharide composed approximately 46% and 30% rhamnose and, addition, contained 21% uronic acid O -acetyl. Upon deacetylation by mild alkaline treatment, PS-60 brittle, firm, optically clear gel. This gelling property thermoreversible. gel exhibited excellent heat stability withstood...
Glutathione-independent prostaglandin D synthase [prostaglandin-H2 D-isomerase; (5Z,13E)-(15S)-9 alpha,11 alpha-epidioxy-15-hydroxyprosta-5,13-dienoate D-isomerase, EC 5.3.99.2] is an enzyme responsible for biosynthesis of D2 in the central nervous system. In situ hybridization with antisense RNA indicated that mRNA was predominantly expressed leptomeninges, choroid plexus, and oligodendrocytes adult rat brain. The findings agree those obtained by immunohistochemical staining antibodies...
Vibrio parahaemolyticus was observed to adsorb onto chitin particles and copepods. The efficiency of adsorption found be dependent on pH the concentration NaC1 other ions in seawater. Highest water samples collected from Chesapeake Bay lowest open sea. V. adborb with highest several bacterial strains tested. Escherichia coli Pseudomonas fluorescens did not chitin. effect is considered one major factors determining distribution this species affecting annual cycle estuarine system.
Nanostructured gradient gels with unique bending properties due to their deswelling characteristics are presented. These readily fabricated via electrophoresis followed by photo-polymerization, and subsequent silica extraction. Differences in the physical between both sides of driving force behind gels.

The development of high-performance biobased polymers such as polyimides (PIs) is indispensable to establish a sustainable green society, but it very difficult due the incompatibility their monomeric aromatic diamines with microorganisms. Here, we developed PIs from bioavailable diamines, which were photodimers 4-aminocinnamic acid (4ACA) derived genetically manipulated Escherichia coli. These PI films showed ultrahigh thermal resistance T10 values over 425 °C and no Tg under 350 °C, highest...
Porous hydrogels possessing mechanical toughness were prepared from sacran, a supergiant liquid crystalline (LC) polysaccharide produced Aphanothece sacrum. First, layered by thermal cross-linking of film cast over sacran LC solution. Then, anisotropic pores constructed using freeze-drying technique on the water-swollen hydrogels. Scanning electron microscopic observation revealed that observable only side faces sponge materials parallel to structure but never top or bottom faces. The pore...
A Bay-wide survey of the distribution Vibrio parahaemolyticus was carried out in Chesapeake Bay during May 1972, to determine whether annual cycle V. which observed occur Rhode River subestuary took place other parts Bay. In an earlier study, April early June, when water temperature rises from 14 19 C, found be a critical period organism River, since this is time initiated. Results however, revealed that could not column 1972. Neverthless, several samples sediment and plankton yielded...
Gold nanorods (AuNRs) are confirmed to have excellent and repeated photothermal properties under near-infrared (NIR)-light irradiation above 780 nm. However, AuNRs easily leaked out from local pathological tissues circulated in the body, reducing therapy (PTT) efficacy. By complexing with a scaffold via interactions, might be dispersed fixed tumor site. Thus, based on mussel-mimetic adhesion concept, were designed coated polydopamine (PDA), then prepared polydopamine-coated (AuNR-PDA)...
Carbon fiber (CF) is widely used in the preparation of carbon-fiber-reinforced polymer composites (CFRP) which it combined with epoxy resin due to its good mechanical properties. Thermosetting bisphenol A resin, as one most common materials, a non-renewable resource, leading heavy environmental burden and resource waste. To solve above problems achieve high thermal properties comparable those A, herein, high-performance, degradable recyclable bio-based was developed by reacting lignin...
Amphiphilic graft copolymers consisting of poly(γ-glutamic acid) (γ-PGA) as the hydrophilic backbone and l-phenylalanine ethylester (L-PAE) hydrophobic side chain were synthesized by grafting L-PAE to γ-PGA. The nanoparticles prepared a precipitation method, about 200 nm-sized obtained due their amphiphilic properties. hydrolytic enzymatic degradation these γ-PGA was studied gel permeation chromatography (GPC), scanning electron microscopy (SEM), dynamic light scattering (DLS) 1H NMR...

Reversible size changes in degradable nanoparticles composed of bio-based cinnamate derivative copolymers, poly(3,4-dihydroxycinnamic acid-co-4-hydroxycinnamic acid) [P(3,4DHCA-co-4HCA)], were observed for the first time. The 860 nm diameter decreased to almost one-half (420 nm) during UV irradiation over 280 and rapidly recovered 620 upon subsequent at 254 nm. Results from UV−vis 1H NMR spectra suggested that diameter-changing phenomena corresponded [2 + 2] cycloaddition formation cleavage...
We extracted the megamolecular polysaccharide sacran, which contains carboxylate and sulfate groups, from jellylike extracellular matrix (ECM) of cyanobacterium Aphanothece sacrum, has mineral adsorption bioactivity. investigated gelation properties sacran binding with various heavy metal ions. The chain adsorbed heavier ions such as indium, rare earth metals, lead more efficiently to form gel beads. In addition, trivalent onto chains than did divalent investigation ion ratio on demonstrated...
