we introduce a new smooth, non-toxic, biocompatible method for cross-linking of gum tragacanth (gt), a polysaccharide of natural origin, in order to serve as a new supporting matrix for immobilization systems.  the modified gum is used as a matrix for the catalysis of the conversion of benzyl penicillin to 6-aminopenicillanic acid (6-apa) by means of escherichia coli atcc11105 with penicillin g...

The importance of macrophage procoagulant activity (PCA) to cell migration is presumed. In this study we assayed the relationship between the two functions in guinea-pig peritoneal resident macrophages and cells elicited by a sterile inflammation induction, which lasted up to 6 days. The findings pointed to an in vivo induction of PCA in macrophages, which declined with time during inflammation...

We describe a format for production of protein arrays termed 'protein in situ array' (PISA). A PISA is rapidly generated in one step directly from PCR-generated DNA fragments by cell-free protein expression and in situ immobilisation at a surface. The template for expression is DNA encoding individual proteins or domains, which is produced by PCR using primers designed from information in DNA d...

We describe the preparation of a thermoresponsive microgel, which can non-covalently immobilize active proteins with enhanced biocatalytic performance in organic solvents and easy reusability due to the porous microstructure and temperature responsive property.

This paper reviews the current evidence available on the practice of spinal immobilisation in the prehospital environment. Following this, initial conclusions from a consensus meeting held by the Faculty of Pre-hospital Care, Royal College of Surgeons of Edinburgh in March 2012 are presented.

BACKGROUND Scaphoid nonunion is very rare in childhood. CASE REPORT A 14 year old boy with scaphoid nonunion confirmed with CT did not past scheduled surgery. In spite of the short period of immobilisation union occurred and two years after the injury he was completely asymptomatic. CONCLUSIONS We suspect that injury to the scaphoid, in this case may have accelerated the union shortly befor...

Blood-contacting devices have emerged in the 21st century as go-to clinical treatment for severe cardiovascular diseases. Due to their poor hemocompatibility, many coatings been developed improve biocompatibility with limited success due lack of robustness biomolecule conjugation. In this paper, we propose a new self-protonating, plasma polymerized, superimposed multi-layered nanoreservoir coat...

The present article draws a general picture of non-conventional methods for biomolecules immobilization. The technologies presented are based either on original solid supports or on innovative immobilization processes. Polydimethylsiloxane elastomer will be presented as a popular immobilization support within the biochip developer community. Electro-addressing of biomolecules at the surface of ...

Treatment of the wrong body part due to incorrect setup is among the leading types of errors in radiotherapy. The purpose of this paper is to report an efficient automatic patient safety system (PSS) to prevent gross setup errors. The system consists of a pair of charge-coupled device (CCD) cameras mounted in treatment room, a single infrared reflective marker (IRRM) affixed on patient or immob...

A DNA piezoelectric biosensing method for real-time detection of Escherichia coli O157:H7 in a circulating-flow system was developed in this study. Specific probes [a 30-mer oligonucleotide with or without additional 12 deoxythymidine 5'-monophosphate (12-dT)] for the detection of E. coli O157:H7 gene eaeA, synthetic oligonucleotide targets (30 and 104 mer) and PCR-amplified DNA fragments from ...
