Thin materials made from elastomeric polymers such as polydimethylsiloxane (PDMS) and polyurethane (PU) can be both, compliant resilient. Their mechanical robustness flexibility will make them great candidates for applications in the human body where space is limited repeated deformations occur. Nonetheless, current medical of foil-like products are mainly restricted to inflatable balloon parts...

Well-intentioned attempts by the Senate Finance Committee to improve the content and quality of continuing medical education (CME) offerings had the unanticipated consequence of decimating academically oriented history of medicine conferences. New guidelines intended to keep CME courses free of commercial bias from the pharmaceutical industry were worded in a fashion that caused CME officials a...

Xylofucoglucuronan from Spatoglossum schröederi algae was tested as a support for antibiotic immobilization. The polysaccharide (20 mg in 6 ml) was first activated using carbodiimide, 1-ethyl-3-(3-dimethylamino-propyl)carbodiimide methiodide (20 mg in 2 ml), under stirring for 1 h at 25 masculine C and pH from 4.5 to 5.0. After adjusting the pH to 8.0, either gentamicin or amikacin (62.5 mg in ...

Transducin (T), a GTP-binding protein involved in phototransduction of rod photoreceptor cells, is a heterotrimer arranged as two units, the alpha-subunit (T alpha) and the beta gamma-complex (T beta gamma). The role of the carboxyl groups in T was evaluated by labeling with N,N'-dicyclohexylcarbodiimide (DCCD) and 1-ethyl 3-(3-dimethylaminopropyl) carbodiimide (EDC). Only a minor effect on the...

Working with delicate tissue can be a complicating factor when performing immunohistochemical assessment. Here, we present a method that utilizes a ring-supported hydrophilized PTFE membrane to provide structural support to both living and fixed tissue during immunohistochemical processing, which allows for the use of a variety of protocols that would otherwise cause damage to the tissue. First...

Modification of the three carboxyl groups on adrenodoxin using a water-soluble carbodiimide (1-ethyl-3-(3-dimethylaminopropyl)carbodiimide) caused a weakening of the binding of this iron-sulfur protein to both its electron donor protein, adrenodoxin reductase, and its electron acceptor protein, cytochrome P-450scc. Based upon the proximity of the modified groups, the site on adrenodoxin for int...

This paper discusses recent research on methods for estimating configuration parameters for the Matrix Comparator used for linking unstandardized or heterogeneously standardized references. The matrix comparator computes the aggregate similarity between the tokens (words) in a pair of references. The two most critical parameters for the matrix comparator for obtaining the best linking results a...
