Legal aspects in implantable defibrillator extraction

Medicine, Science and the Law, 2013
At the Institute of Legal Medicine in Chieti, a case of iatrogenic superior vena cava perforation was observed during laser extraction of an infected biventricular implantable cardiac defibrillator. The presentation of this particular case represented a starting point for studying the occurrence of similar complications in literature, since their ...

TECHNICAL ASPECTS OF EXTRACTIVE ENZYME PURIFICATION

Annals of the New York Academy of Sciences, 1981
We see the advantages of extraction processes for large-scale enzyme isolation and purification in the high capacity of the method, savings in process time and energy, high activity yields and the possibilities for continuous processing at all stages.

Biological aspects of testicular sperm extraction

European Journal of Obstetrics & Gynecology and Reproductive Biology, 2000
Since the first reports of successful pregnancies after treatment with intra cytoplasmic sperm injection (ICSI) in humans, intensive investigations focused on the use of testicular spermatozoa and immature sperm cells in the treatment of azoopsermic patients.

Chemical aspects of gel extraction

Chemical Engineering Science, 1986
Abstract Dilute aqueous solutions can be effectively concentrated with crosslinked partially hydrolysed polyacrylamide gels. Because the gels are near their critical point, they can be regenerated with small changes in pH. The selectivity of concentrating nonelectrolyte solutes can be adjusted by changes in gel crosslinking; the selectivity of ...

Some aspects of synergic extractions with chelating extractants

Journal of Radioanalytical Chemistry, 1979
With the exception of the formation of coordinatively saturated adducts, synergic extractions using chelating extractants are reviewed. Emphasis is laid on less common synergic systems. These include the formation of adducts containing also inorganic anions, extraction of chelates in the presence of bulky organic cations, influence of various anions on

Some immunochemical aspects of HD-brain extracts

Clinical Immunology and Immunopathology, 1983
Cortical gray matter extracts of patients with Huntington's disease (HD) were investigated for their antigenic properties with serum from both HD patients and normal controls. Both patient and control sera appeared to precipitate two closely migrating proteins of MW 14.4K and 15K, which could be found in normal brain preparations only at much lower ...

Practical Aspects of In-Situ Electrokinetic Extraction

Journal of Environmental Engineering, 1999
Electrokinetic extraction in an emerging technology that can be used to remove contaminants from heterogeneous fine-grained soils in situ. Contaminants in the subsurface are removed by the application of a direct-current electric field across the contaminated soil.

Extraction instrumentale difficile : Aspects pédiatriques

2011
Actuellement environ 10 a 15 % des accouchements par voie basse necessitent une aide instrumentale, ventouse, forceps ou plus rarement spatules. Des complications chez le nouveau-ne peuvent etre observees, notamment au niveau de l’extremite cephalique. Elles sont rares et le plus souvent benignes. Neanmoins, lorsque l’extraction fœtale a ete difficile,
