Fourier transform infrared determination of CO 2 evolved from carbonate in carbonated apatites
2000
A quantitative method based on FTIR has been developed to determine carbonate in synthetic apatites. The method measures the evolved CO2 after reaction of 50 mg apatite with 2 mL of hydrochloric acid (0.5 M) in a reaction vessel, heated to 40 degrees C. The CO2 evolved was swept by a carrier of nitrogen to a laboratory-made infrared gas cell of 39 mm pathlength and 490 microL volume. The signals were recorded as a function of time and the areas of the chemigram peaks obtained from the measurements in the wavenumber range of 2,500-2,150 cm(-1), were interpolated using a calibration curve. The method can be used to study apatites with carbonate contents below 0.2% with a sampling frequency of…
Characterisation of the structure-function relationship of the Bacillus thuringiensis Vip3A insecticidal proteins
2017
L'agricultura contemporània exigeix cada cop més un ús sostenible d’agroquímics per tal de reduir l'impacte ambiental i el risc per la salut del consumidor. Alguns bacteris entomopatògens produeixen proteïnes insecticides que s'acumulen en cossos d'inclusió o cristalls paraesporales (com ara les proteïnes Cry i Cyt), així com proteïnes insecticides que són secretades al medi de cultiu. Entre les últimes, hi ha les proteïnes Vip, que es divideixen en quatre famílies d'acord amb la seva identitat d'aminoàcids. Les proteïnes Vip1 i Vip2 actuen com toxines binàries i són tòxiques per a alguns coleòpters i hemípters. Per la família de les Vip4, que és l’última família de proteïnes Vip descoberta…
Laryngeal Mask Airway Position and the Risk of Gastric Insufflation
1998
A potential risk of the laryngeal mask airway (LMA) is an incomplete mask seal causing gastric insufflation or oropharyngeal air leakage.The objective of the present study was to assess the incidence of LMA malpositions by fiberoptic laryngoscopy, and to determine their influence on gastric insufflation and oropharyngeal air leakage. One hundred eight patients were studied after the induction of anesthesia, before any surgical manipulations. After clinically satisfactory LMA placement, tidal volumes were increased stepwise until air entered the stomach, airway pressure exceeded 40 cm H2 O, or air leakage from the mask seal prevented further increases in tidal volume. LMA position in relatio…
Il dovere di soccorso in mare e il diritto di obbedire al diritto (internazionale) del comandante della nave privata
2019
Shipmasters are commonly considered the addressees of an international legal duty to rescue at sea. This article describes the evolution of international law in this field, from the first maritime conventions of the 1910's to the IMO Safety Committee's resolutions of the 2010's. It then argues that behind the duty to rescue there is a hidden right of the shipmaster. This right has a moral pedigree and is functional to the full compliance of the duty itself. It can be enforced in the national legal order against any State (or private entity) that tries to obstruct the shipmaster's activities of assistance or to penalize her or him for the assistance given. National judges enforce this right …
Visual and optical performance with hybrid multifocal intraocular lenses
2010
During the past years, the wish to become independent of spectacles has been growing among cataract and presbyopic patients due to many factors, such as the increase in near visual demands, the aesthetic need for a spectacle-free image and ageing of refractive surgery patients, among others. This review assesses recently published studies that analyse visual and optical performance through different metrics of eyes implanted with multifocal intraocular lenses (IOLs), particularly hybrid IOL designs. The published evidence suggests that hybrid multifocal IOLs provide very good outcomes in a number of visual and optical performance parameters. Patients implanted with this type of IOL obtain a…
Synthesis, physico-chemical and biological study of trialkylsiloxyalkyl amine coated iron oxide/oleic acid magnetic nanoparticles for the treatment o…
2008
New original water-soluble magnetic nanoparticles based on natural components, magnetite–oleic acid–biologically active silyl modified alkanolamine, were synthesized. Physico-chemical characterization, i.e. magnetic properties, concentration of magnetite, size of iron oxide core, of the nanoparticles synthesized and the corresponding magnetic fluids obtained, was carried out. Magnetic fluids were screened for in vitro cytotoxicity concerning human fibrosarcoma (HT-1080), mouse hepatoma (MG-22A) monolayer tumour cell lines and normal mouse fibroblasts (NIH 3T3). They possess low or moderate cytotoxic effects, are non-toxic, exhibit high NO-induction ability and strongly change tumour cell mo…
Unterschiede im Erhaltungszustand zwischen vorderem und hinterem Kreuzband bei rheumatoider Arthritis
2008
In rheumatoid arthritis (RA) we examined the cruciate ligaments of 16 patients by the use of light- and transmission electron microscopy. Considerable differences between the anterior (ACL) and the posterior cruciate ligament (PCL) were observed. The ACL showed dramatic ultrastructural changes, against that the PCL was compact and well conserved. The preservation of PCL in joint surgery can morphologically be recommended. Perhaps the greater inflammatory process on the surface of ACL is responsible for the observed differences.
Synthesis and biological evaluation of dehydroabietic acid derivatives.
2010
A series of C18-oxygenated derivatives of dehydroabietic acid were synthesized from commercial abietic acid and evaluated for their cytotoxic, antimycotic, and antiviral activities.
Bibliometric Analysis of Fitness Equipment: How Scientific Focuses Affect Life-Cycle Approaches and Sustainable Ways of Development
2019
Research Question: Although fitness equipment is recognised worldwide as a tool for physical activities and a sustainable result in optimizing human movements within a wide range of environments, the state of the art and scientific advances have not been analysed from a bibliometric point of view. Research Methods: Using descriptive bibliometric software, this study examined the scientific production, and the most prolific authors, articles, and institutions. Bibliometric maps were used to visualise the content of published articles and to determine the most prolific terms, co-citation, and co-authorship. Results and Findings: A total of 678 original papers were retrieved from 447 journals …
