Abstract Chitosan is a biopolymer that exhibits osteoconductive, enhanced wound healing and antimicrobial properties which make it attractive for use as bioactive coating to improve osseointegration of orthopaedic craniofacial implant devices. Coatings made from 91.2% de-acetylated chitosan were chemically bonded titanium coupons via silane-glutaraldehyde molecules. The bond strength the coatings was evaluated in mechanical tensile tests, their dissolution cyto-compatibility vitro using...

ABSTRACT: A standardized descriptive language for Cheddar cheese flavor was developed and validated. Representative cheeses (240) were collected. Fifteen individuals from industry, academia, government participated in a 3‐d roundtable discussion to generate terms. highly trained panel (n = 11) refined the terms identified references.

Rationale: Matrix metalloproteinases (MMPs)–mediated extracellular matrix destruction is the major cause of development and progression abdominal aortic aneurysms. Systemic treatments MMP inhibitors have shown effectiveness in animal models, but it did not translate to clinical success either because low doses used or systemic side effects inhibitors. We propose a targeted nanoparticle (NP)–based delivery inhibitor at aneurysms site. Such therapy will be an attractive option for preventing...

Power analysis after study completion has been suggested to interpret results. We present 3 methods of estimating power and discuss their limitations. use simulation studies show that estimated can be biased, extremely variable, severely bounded. endorse the practice computing detect a biologically meaningful difference as tool for planning but suggest calculation confidence intervals on parameter interest is appropriate way gauge strength biological meaning

• Climate change could increase the frequency with which plants experience abiotic stresses, leading to changes in their metabolic pathways. These stresses may induce production of compounds that are structurally and biologically different from constitutive compounds. We studied how warming altered precipitation affected composition, structure, biological reactivity leaf litter tannins Acer rubrum at Boston-Area Experiment, Massachusetts, USA. Warmer drier climatic conditions led higher...

Abstract We study the Calogero–Moser derivative nonlinear Schrödinger NLS equation posed on Hardy–Sobolev space with suitable . By using a Lax pair structure for this ‐critical equation, we prove global well‐posedness and initial data sub‐critical or critical ‐mass Moreover, uniqueness of ground states also classify all traveling solitary waves. Finally, in detail class multi‐soliton solutions that they exhibit energy cascades following strong sense such as every

ABSTRACT The relationship between sensory and instrumental texture measurements of natural processed cheeses was studied. A descriptive analysis panel evaluated seven mouth‐evaluated five hand‐evaluated terms. Instrumental included profile (TPA), frequency sweeps, creep. Multivariate analyses showed that many the were highly correlated. Principal component similarities differences in how differentiated by techniques. TPA fundamental rheological tests worked equally well at predicting...

Given the potential for high amounts of variability in yield-affecting soil factors, some property or properties may serve as a basis site-specific management. The objectives this study were to determine selected and relationships between these soybean [Glycine max (L.) Merr.] yield. Soil samples collected from center point 0.5-ha grids three fields analyzed soil-test-extractable Ca, Mg, K, P, pH water, texture. Relative elevation, slope, aspect, yield also determined at points.

Bicuspid aortic valve (BAV) disease is a congenital defect that affects 0.5% to 1.2% of the population and associated with comorbidities including ascending dilation calcific stenosis. To date, although few causal genes have been identified, genetic basis for vast majority BAV cases remains unknown, likely pointing complex heterogeneity underlying this phenotype. Identifying pathways versus individual gene variants may provide an avenue uncovering additional causes consequent...
