Maithili Deshpande, S K Sathe
Surface hydrophobicity (SH) properties of the trimeric storage protein phaseolin (black gram phaseolin [BGP]) of black gram (Vigna mungo) were investigated using 8-anilinonaphthalene-1-sulfonate (ANS) as an extrinsic fluorescent probe. The emission maxima of fluorescence spectra of BGP:ANS complex were blue-shifted to 455 nm as compared to 515 nm for the free ANS. Saturation binding occurred at a dye-to-protein ratio of about 30:1. The quantum yield of the complex increased with increasing ionic strength. The Kd values were 1...

Spatial patterns of trait variation across a species' range have implications for population success and evolutionary change potential, particularly in range-expanding and weedy species that encounter distinct selective pressures at large and small spatial scales simultaneously. We investigated intraspecific trait variation in a common garden experiment with giant ragweed ( Ambrosia trifida ), a highly variable agricultural weed with an expanding geographic range and broad ecological amplitude. Our study included paired populations from agricultural and natural riparian habitats in each of seven regions ranging east to west from the core of the species' distribution in central Ohio to southeastern Minnesota, which is nearer the current invasion front...

Background: Microtia reconstruction is a challenging procedure, especially in developing nations. The most complex part is learning how to fabricate a framework from costal cartilage. We herein propose a training regimen for ear reconstruction with the use of a plastic eraser. Materials and Methods: The texture of a plastic eraser made from polyvinyl chloride is similar to that of human costal cartilage. The first step of the training is carving out the sixth through eighth rib cartilages from a block of plastic eraser...

It is rather challenging to develop photocatalysts based on narrow-band-gap semiconductors for water splitting under solar irradiation. Herein, we synthesized the Cu2 O/Cu2 Se multilayer heterostructure nanowires exposing {111} crystal facets by a hydrothermal reaction of Se with Cu and KBH4 in ethanol amine aqueous solution and subsequent annealing in air. The photocatalytic H2 production activity of Cu2 O/Cu2 Se multilayer heterostructure nanowires is dramatically improved, with an increase on the texture coefficient of Cu2 O(111) and Cu2 Se(111) planes, and thus the exposed {111} facets may be the active surfaces for photocatalytic H2 production...

Adult ocean sunfish are the heaviest living teleosts. They have no axial musculature or caudal fin. Propulsion is by unpaired dorsal and anal fins; a pseudocaudal fin ('clavus') acts as a rudder. Despite common perception, young sunfish are active predators that swim quickly, beating their vertical fins in unison to generate lift-based propulsion and attain cruising speeds similar to salmon and marlin. Here we show that the thick subcutaneous layer (or 'capsule'), already known to provide positive buoyancy, is also crucial to locomotion...

Long terminal repeat (LTR) retrotransposon is the most abundant DNA component and is largely responsible for plant genome size variation. Although it has been studied in plant species, very limited data is available for cotton, the most important fiber and texture crop. In this study, we performed a comprehensive analysis of LTR retrotransposon families across four cotton species. In tetraploid Gossypium species, LTR retrotransposon families from the progenitor D genome had more copies in D-subgenome, and families from the progenitor A genome had more copies in A-subgenome...

Sage seed gum (SSG) is a promising biopolymer candidate for utilization and substitution prevalent galactomannan gels of interest in soft biomaterial applications. Herein, physicochemical and rheo-mechanical properties of SSG matrix reinforced by various titanium dioxide (TiO2 ) nanoparticles loading (0-25wt%) were monitored. Particle size and density of the nanocomposite increased with raising TiO2 content, due to the creation of more compact agglomerated and aggregated microstructure. Increasing the particle size resulted in lower electrophoretic mobility of SSG-TiO2 systems upon nanoparticles addition, confirmed the adsorption of TiO2 on the SSG macromolecule...

Root-knot nematodes of the genus Meloidogyne are recognised worldwide as a major production constraint in crops of primary economic importance. Knowledge of their diversity and prevalence, as well as the major environmental and agronomical cues for understanding their distribution in specific areas is of vital importance for designing control measures to reduce significant damage. We provide the first detailed information on the diversity, distribution and levels of Meloidogyne species infecting wild and cultivated olive soils in a wide-region in southern Spain that included 499 sampling sites...

Electric field control of interfacial magnetism promises low power consuming and versatile spintronic devices. More specifically, in ultra thin heavy metal/ferromagnet/insulator heterostructures, voltage gating has been shown to locally and dynamically tune properties like perpendicular magnetic anisotropy and saturation magnetization. However its effect on the nowadays widely explored antisymmetric exchange property called interfacial Dzyaloshinskii-Moriya Interaction (DMI) has not been addressed yet. This DMI plays a fundamental role in stabilizing magnetic textures known as skyrmions envisaged for memory and logic based spintronic devices...

The 2.1-billion-year-old (Ga) Francevillian series in Gabon hosts some of the oldest reported macroscopic fossils of various sizes and shapes, stimulating new debates on the origin, evolution and organization of early complex life. Here, we document ten representative types of exceptionally well-preserved mat-related structures, comprising "elephant-skin" textures, putative macro-tufted microbial mats, domal buildups, flat pyritized structures, discoidal microbial colonies, horizontal mat growth patterns, wrinkle structures, "kinneyia" structures, linear patterns and nodule-like structures...

Nuclear alterations are a hallmark of many types of cancers, including prostate cancer (PCa). Recent evidence shows that subvisual changes, ones that may not be visually perceptible to a pathologist, to the nucleus and its ultrastructural components can precede visual histopathological recognition of cancer. Alterations to nuclear features, such as nuclear size and shape, texture, and spatial architecture, reflect the complex molecular-level changes that occur during oncogenesis. Quantitative nuclear morphometry, a field that uses computational approaches to identify and quantify malignancy-induced nuclear changes, can enable a detailed and objective analysis of the PCa cell nucleus...

Background: Soft-tissue deficiencies pose a challenge in a variety of disease processes when the end result is exposure of underlying tissue. Although multiple surgical techniques exist, the transposition of tissue from one location to another can cause donor-site morbidity, long incisions prone to dehiscence, and poor patient outcomes as a result. Use of tissue expansion prior to grafting procedures has been shown to have success in increasing available soft tissue to aid in repairing wounds...

Current morphometric methods that comprehensively measure shape cannot compare the disparate leaf shapes found in seed plants and are sensitive to processing artifacts. We explore the use of persistent homology, a topological method applied as a filtration across simplicial complexes (or more simply, a method to measure topological features of spaces across different spatial resolutions), to overcome these limitations. The described method isolates subsets of shape features and measures the spatial relationship of neighboring pixel densities in a shape...

We report, for the first time, correlations between crystal structure, microstructure and magnetofunctional response in directionally solidified [110]-textured Fe83 Ga17 Er x (0 < x < 1.2) alloys. The morphology of the doped samples consists of columnar grains, mainly composed of a matrix phase and precipitates of a secondary phase deposited along the grain boundary region. An enhancement of more than ~275% from ~45 to 170 ppm is observed in the saturation magnetostriction value ( &lambda;s ) of Fe83 Ga17 Erx alloys with the introduction of small amounts of Er...

The integrity of image content is essential, although most watermarking algorithms can achieve image authentication but not automatically repair damaged areas or restore the original image. In this paper, a self-recovery reversible image watermarking algorithm is proposed to recover the tampered areas effectively. First of all, the original image is divided into homogeneous blocks and non-homogeneous blocks through multi-scale decomposition, and the feature information of each block is calculated as the recovery watermark...
