Limited value of ultrasound assessment in patients with poor outcome after carpal tunnel release surgerys

[EN] OBJECTIVE: To determine the value of ultrasonography in the assessment of patients with idiopathic carpal tunnel syndrome (CTS) and poor outcome after carpal tunnel release. METHODS: A total of 88 consecutive patients with CTS (104 hands) underwent open surgical release of the median nerve. Ultrasound (US) examination was performed blind to any patient's data. The median nerve area at tunnel inlet and outlet, the retinaculum distance, and the flattening ratio were measured. The main outcome variable was the patient's overall satisfaction using a five-point Likert scale (1 = worse, 2 = no change, 3 = slightly better, 4 = much better, 5 = cured) at 3 months postoperatively. Pre- and postoperative ultrasonographic findings in relation to clinical outcome were analysed. RESULTS: Improvement (scores 4 or 5 on the Likert scale) was recorded in 75 hands (72%). After carpal tunnel release, the cross-sectional area at tunnel inlet decreased from a mean of 14.2 to 13.3 mm2 in the group with clinical improvement and also from a mean of 12.5 to 11.6 mm2 in the group with no change or slight improvement. No significant changes in the cross-sectional area at tunnel outlet, retinaculum distance, and flattening ratio were observed. CONCLUSION: Reduction of the median nerve cross-sectional area at tunnel inlet at 3 months after carpal tunnel release was similar in patients reporting cure or great improvement and in those with slight or no improvement. Ultrasonography is of limited value in assessment of patients with poor outcome after median nerve release.

Trabajo presentado como requisito parcial para la obtención del Título de Máster Oficial en Cultivos Marinos, otorgado por la Universidad de Las Palmas de Gran Canaria (ULPGC), el Instituto Canario de Ciencias Marinas (ICCM), y el Centro Internacional de Altos Estudios Agronómicos Mediterráneos de Zaragoza (CIHEAM)

Embryonic and larval development of haliotis tuberculata coccinea reeve: an indexed micro-photographic sequence

[EN] First description of the complete embryo and larval development of the Canarian abalone (Haliotis tuberculata coccinea Reeve.) was conducted along 39 stages from fertilization to the appearance of the third tubule on the cephalic tentacles and illustrated in a microphotographic sequence. Eggs obtained by induced spawning with hydrogen peroxide from the GIA captive broodstock were stocked at a density of 10 eggs/mL and kept at 23 0.5 BC for 62 h until the formation of the third tubule. Live eggs and larvae were continuously observed on a 24 h basis at a 3400 magnification under transmitted light. At each stages, specific morphological features, illustrated by microscopic photographs, were described, as well as the time required for their apparition. Fertilized eggs diameter was 205 8 mm (mean SD), whereas length and width of larvae ready to undergo metamorphosis were 216.6 5.3 mmand 172 8.8 mm, respectively. Knowledge on the larval morphological development acquired through this study will contribute to the improvement of larval rearing techniques for this abalone species.

Zooplankton oxygen consumption and nutrient release in relation to species composition, animals size and enviromental conditions in the Baltic Sea during May and August

[EN] Zooplankton metabolism in terms of oxygen consumption and ñutrient reléase (ammonia, phosphate) were measiu'ed in the Baltic Sea, a températe área with high envirormiental changes both in space and in time. Plankton of the surface layer were analysed with balance measurements in 4 size classes between 50 and 1000 nm during spring in 1988, 1990 and 1991, in summer 19^8 and 1990 as well. The use of electrón transport system (ETS), and the Glutamate Dehydrogenase (GDH) activity as indicators for respiration and ammonia reléase respectively, enlarged the data density and made a three dimensional resolution available (May 1990, 1991). Data are in the range of the latitudinal dependend magnitude. They reflect slight interannual, more seasonal and regional aspects. Animáis size, temperature, food concentration, and species composition influence the specific rates

Importance of dietary n-3 hufa for eye development and cone formation along gilthead seabream sparus aurata larval development.

[EN] Being fish larvae visual feeders, vision plays an important role in larval orientation at first feeding (Blaxter, 1986). Larval trophic behaviour is closely related with the development of the visual capacity, which directly depends on retina organogenesis. In sparids, such as Pagrus major (Kawamura, 1984) and Pagrus auratus (Pankhurst, 1996), the most important changes in the eye structure occur along the lecitotrophic stage as a preparation for prey capture. Neuringer et al.,(1988) has established a critical role for n-3 polyunsaturated fatty acids and, particularly docosahexaenoic acid (DHA) in neural and retinal tissue functions in mammals. Similarly, in larval fish there is a high demand of DHA to form nervous membranes. Bell and Dick (1993) found photoreceptors in the eye, rods and cones accumulate and selectively retain DHA in external segments.Bell et al. (1995) found that feeding juvenile herring a DHA poor Artemia diet during the period of rod development resulted in impaired vision at low light intensities, when rod vision is essential.

Effect of culture system and diet in early larval stages over skeletal deformities development in gilthead sea bream

[ES] Main deformities such as lordosis, opercular deformities and upper/lower jaws shortening are considered as quality descriptors in commercial marine fish fry production and seem to be related with larval culture conditions in early larval stages. The aim of this work was to obtain information about the contribution of the diet and rearing system to the apparition of these abnormalities in gilthead sea bream (Sparus aurata) larvae in semi-industrial scale facilities. For that purpose, two different larval rearing systems semi-intensive and intensive were compared; besides, two different rotifer enrichments, DHA Protein Selco, (Inve Aquaculture, Dendermonde, Belgium) (R1) and Red Pepper Paste, (Bernaqua bvba, Turnhout, Belgium) were tested in the intensive system. Biochemical composition of larvae, preys and commercial products was analysed. At 50 days post hatching six hundred fish per treatment were individually studied under stereoscope and deformity frequency recorded. Besides at 95 days post hatching fry were soft X ray monitored. Both rotifer enrichment and rearing system affected survival, growth and deformity frequency. Rearing system did not affect total larvae fatty acid content except at 20 dah, where DHA were significantly higher and EPA significantly lower in Semi-intensive system. A significantly lower percentage of deformity rates together with better survival and growth were obtained in the semi-intensive system. In dietary treatment, rotifer enrichment significantly affected larval survival. R1 rotifers enrichment significantly (P<0.05) improved survival when compared to fed R2 larvae. The content of DPA was significantly (P<0.05) higher in R2 fed larvae reflecting the R2 rotifers content of this fatty acid. The level of this FA tended to decrease in concordance with the rotifers replacement by artemia in the diet. The effects n-3-HUFA and DPA (22:5n-6) over larval survival and skeletal deformities development is discussed.

Development of skeletal deformities in Gilthead sea bream (Sparus aurata) reared under different larval culture and dietary conditions

[EN] Main deformities such as lordosis, opercular deformities and upper/lower jaws shortening are considered as quality descriptors in commercial marine fish fry production and seem to be related at least with larval culture conditions in early larval stages. The aim of this work was to obtain information about the contribution of the diet and rearing system to the apparition of these abnormalities in gilthead sea bream (Sparus aurata) larvae in semi-industrial scale facilities. For that purpose, two different larval rearing systems semi-intensive and intensive were compared by duplicate and with the same live feed enrichments; besides, two different rotifer enrichments were tested in an intensive system. Biochemical composition of larvae, preys and commercial products was analysed. At 50 days post hatching six hundred fish per treatment were individually studied under stereoscope and abnormalities frequency recorded. At 95 days post hatching fry were soft X ray monitored as well. Survival and malformation frequency were significantly different between treatments, the effect of diet and system are discussed. A significantly lower percentage of deformity rates together with better survival and growth were obtained in the semi-intensive system, whereas the rotifer enrichment significantly affected larval survival.

Kiwifruit bud release from dormancy: effect of exogenous cytokinins

A new formulate containing citokinins, that is commercialized as Cytokin, has been introduced as dormancy breaking agents. During a three-years study, Cytokin was applied at different concentrations and application times in two producing areas of the Emilia-Romagna region to verify its efficacy as a DBA. Cytokin application increased the bud break and showed a lateral flower thinning effect. Moreover, treated vines showed an earlier and more uniform flowering as compared to control ones. Results obtained on the productive performance revealed a constant positive effect in the fruit fresh weight at harvest. Moreover, Cytokin did not cause any phytotoxicity even at the highest concentrations. Starting from the field observation, which suggested the involvement of cytokinins in kiwifruit bud release from dormancy, 6-BA was applied in open field condition and molecular and histological analyses were carried out in kiwifruit buds collected starting from the endo dormant period up to complete bud break to compare the natural occurring situation to the one induced by exogenous cytokinin application. In details, molecular analyses were set up on to verify the expression of genes involved in the reactivation of cell cycle: cyclin D3, histone H4, cyclin-dependent kinase B, as well as of others which are known to be up regulated during bud release in other species, i.e.isopenteniltransferases (IPTs), which catalyze the first step in the CK biosynthesis, and sucrose synthase 1 and A, which are involved in the sugar supplied. Moreover, histological analyses of the cell division rate in kiwifruit bud apical meristems were performed. These analyses showed a reactivation of the cell divisions during bud release and changes in the expression level of the investigated genes.

Sustained-release formulations for compounds underlying intestinal drug efflux

ZusammenfassungDie Sekretion von Arzneistoffen aus Darmzellen zurück ins Darmlumen, die durch intestinale Transporter wie P-Glykoprotein (P-GP) vermittelt wird, stellt eine bekannte Quelle für unvollständige und variable Bioverfügbarkeiten und für Interaktionen mit anderen Arzneimitteln und Nahrungsbestandteilen dar. Dennoch liegen bisher keine Veröffentlichungen vor, die sich mit daraus resultierenden Konsequenzen für die Entwicklung neuer peroraler Darreichungsformen befassen. Ziel der vorliegenden Arbeit war es, deutlich zu machen, dass dem Auftreten von intestinalen Sekretionsphänomenen bei der Entwicklung von Retardarzneimitteln Rechnung getragen werden muss.Dazu wurden effektive Permeabilitäten für den Modellarzneistoff Talinolol in unterschiedlichen Darmabschnitten anhand eines Rattendarmperfusionsmodells bestimmt.Des weiteren wurde eine Retardformulierung für den Modellarzneistoff Talinolol entwickelt. Dabei wurde gezeigt, dass die Verwendung unterschiedlicher Puffer als Wirkstofffreisetzungmedien zur Ausbildung unterschiedlicher Talinolol-Kristallstrukturen führt.Die neu entwickelten Retardmatrixtabletten wurden mit Hilfe des Pharmakokinetik-Computersoftwareprogrammes Gastro Plus® evaluiert. Das Zusammenspiel von verlangsamter Wirkstofffreigabe aus der Arzneiform und intestinaler Sekretion führte zu einer deutlich verringerten Bioverfügbarkeit der Modellsubstanz Talinolol aus der Retardformulierung im Vergleich zu schnellfreisetzenden Arzneiformen.Daher sollte der Einfluß intestinaler sekretorischer Transporter wie P-GP bei der Entwicklung von Retardarzneiformen unbedingt berücksichtigt werden.

The release of zinc and lead from mine tailings

Mining and processing of metal ores are important causes of soil and groundwater contamination in many regions worldwide. Metal contaminations are a serious risk for the environment and human health. The assessment of metal contaminations in the soil is therefore an important task. A common approach to assess the environmental risk emanating from inorganic contaminations to soil and groundwater is the use of batch or column leaching tests. In this regard, the suitability of leaching tests is a controversial issue. In the first part of this work the applicability and comparability of common leaching tests in the scope of groundwater risk assessment of inorganic contamination is reviewed and critically discussed. Soil water sampling methods (the suction cup method and centrifugation) are addressed as an alternative to leaching tests. Reasons for limitations of the comparability of leaching test results are exposed and recommendations are given for the expedient application of leaching tests for groundwater risk assessment. Leaching tests are usually carried out in open contact with the atmosphere disregarding possible changes of redox conditions. This can affect the original metal speciation and distribution, particularly when anoxic samples are investigated. The influence of sample storage on leaching test results of sulfide bearing anoxic material from a former flotation dump is investigated in a long-term study. Since the oxidation of the sulfide-bearing samples leads to a significant overestimation of metal release, a feasible modification for the conduction of common leaching tests for anoxic material is proposed, where oxidation is prevented efficiently. A comparison of leaching test results to soil water analyzes have shown that the modified saturation soil extraction (SSE) is found to be the only of the tested leaching procedures, which can be recommended for the assessment of current soil water concentrations at anoxic sites if direct investigation of the soil water is impossible due to technical reasons. The vertical distribution and speciation of Zn and Pb in the flotation residues as well as metal concentrations in soil water and plants were investigated to evaluate the environmental risk arising from this site due to the release of metals. The variations in pH and inorganic C content show an acidification of the topsoil with pH values down to 5.5 in the soil and a soil water pH of 6 in 1 m depth. This is due to the oxidation of sulfides and depletion in carbonates. In the anoxic subsoil pH conditions are still neutral and soil water collected with suction cups is in equilibrium with carbonate minerals. Results from extended x-ray absorption fine-structure (EXAFS) spectroscopy confirm that Zn is mainly bound in sphalerite in the subsoil and weathering reactions lead to a redistribution of Zn in the topsoil. A loss of 35% Zn and S from the topsoil compared to the parent material with 10 g/kg Zn has been observed. 13% of total Zn in the topsoil can be regarded as mobile or easily mobilizable according to sequential chemical extractions (SCE). Zn concentrations of 10 mg/L were found in the soil water, where pH is acidic. Electron supply and the buffer capacity of the soil were identified as main factors controlling Zn mobility and release to the groundwater. Variable Pb concentrations up to 30 µg/L were observed in the soil water. In contrast to Zn, Pb is enriched in the mobile fraction of the oxidized topsoil by a factor of 2 compared to the subsoil with 2 g/kg Pb. 80% of the cation exchange capacity in the topsoil is occupied by Pb. Therefore, plant uptake and bioavailability are of major concern. If the site is not prevented from proceeding acidification in the future, a significant release of Zn, S, and Pb to the groundwater has to be expected. Results from this study show that the assessment of metal release especially from sulfide bearing anoxic material requires an extensive comprehension of leaching mechanisms on the one hand and on weathering processes, which influence the speciation and the mobility of metals, on the other hand. Processes, which may change redox and pH conditions in the future, have to be addressed to enable sound decisions for soil and groundwater protection and remediation.

Effect of drug physicochemical properties on the release from liposomal systems in vitro and in vivo

Liposomes were discovered about 40 years ago by A. Bangham and since then they became very versatile tools in biology, biochemistry and medicine. Liposomes are the smallest artificial vesicles of spherical shape that can be produced from natural untoxic phospholipids and cholesterol. Liposome vesicles can be used as drug carriers and become loaded with a great variety of molecules, such as small drug molecules, proteins, nucleotides and even plasmids. Due to the variability of liposomal compositions they can be used for a large number of applications. In this thesis the β-adrenoceptor antagonists propranolol, metoprolol, atenolol and pindolol, glucose, 18F-Fluorodeoxyglucose (FDG) and Er-DTPA were used for encapsulation in liposomes, characterization and in vitro release studies. Multilamellar vesicles (MLV), large unilamellar vesicles (LUV) and smaller unilamellar vesicles (SUV) were prepared using one of the following lipids: 1,2-Dimyristoyl-sn-Glycero-3-Phosphocholine (DMPC), 1,2-Distearoyl-sn-Glycero-3-Phosphocholine (DSPC), Phospholipone 90H (Ph90H) or a mixture of DSPC and DMPC (1:1). The freeze thawing method was used for preparation of liposomes because it has three advantages (1) avoiding the use of chloroform, which is used in other methods and causes toxicity (2) it is a simple method and (3) it gives high entrapping efficiency. The percentage of entrapping efficiencies (EE) was different depending on the type and phase transition temperature (Tc) of the lipid used. The average particle size and particle size distribution of the prepared liposomes were determined using both dynamic light scattering (DLS) and laser diffraction analyzer (LDA). The average particle size of the prepared liposomes differs according to both liposomal type and lipid type. Dispersion and dialysis techniques were used for the study of the in vitro release of β-adrenoceptor antagonists. The in vitro release rate of β-adrenoceptor antagonists was increased from MLV to LUV to SUV. Regarding the lipid type, β-adrenoceptor antagonists exhibited different in vitro release pattern from one lipid to another. Two different concentrations (50 and 100mg/ml) of Ph90H were used for studying the effect of lipid concentration on the in vitro release of β-adrenoceptor antagonists. It was found that liposomes made from 50 mg/ml Ph90H exhibited higher release rates than liposomes made at 100 mg/ml Ph90H. Also glucose was encapsulated in MLV, LUV and SUV using 1,2-Dimyristoyl-sn-Glycero-3-Phosphocholine (DMPC), 1,2-Distearoyl-sn-Glycero-3-Phosphocholine (DSPC), Phospholipone 90H (Ph90H), soybean lipid (Syb) or a mixture of DSPC and DMPC (1:1). The average particle size and size distribution were determined using laser diffraction analysis. It was found that both EE and average particle size differ depending on both lipid and liposomal types. The in vitro release of glucose from different types of liposomes was performed using a dispersion method. It was found that the in vitro release of glucose from different liposomes is dependent on the lipid type. 18F-FDG was encapsulated in MLV 1,2-Dimyristoyl-sn-Glycero-3-Phosphocholine (DMPC), 1,2-Distearoyl-sn-Glycero-3-Phosphocholine (DSPC), Phospholipone 90H (Ph90H), soybean lipid (Syb) or a mixture of DSPC and DMPC (1:1). FDG-containing LUV and SUV were prepared using Ph90H lipid. The in vitro release of FDG from the different types of lipids was accomplished using a dispersion method. Results similar to that of glucose release were obtained. In vivo imaging of FDG in both uncapsulated FDG and FDG-containing MLV was performed in the brain and the whole body of rats using PET scanner. It was found that the release of FDG from FDG-containing MLV was sustained. In vitro-In vivo correlation was studied using the in vitro release data of FDG from liposomes and in vivo absorption data of FDG from injected liposomes using microPET. Erbium, which is a lanthanide metal, was used as a chelate with DTPA for encapsulation in SUV liposomes for the indirect radiation therapy of cancer. The liposomes were prepared using three different concentrations of soybean lipid (30, 50 and 70 mg/ml). The stability of Er-DTPA SUV liposomes was carried out by storage of the prepared liposomes at three different temperatures (4, 25 and 37 °C). It was found that the release of Er-DTPA complex is temperature dependent, the higher the temperature, the higher the release. There was an inverse relationship between the release of the Er-DTPA complex and the concentration of lipid.

Untersuchungen zur biologischen Bekämpfung der Kleidermotte Tineola bisselliella (Hummel 1823) und anderer tineider Textilschädlinge (Lepidoptera: Tineidae) mit parasitoiden Hymenopteren

Nach den Ergebnissen der vorliegenden Arbeit ist eine biologische Bekämpfung von Kleider- und Pelzmotten durch die gezielte Freilassungen von parasitoiden Hymenopteren als deren natürliche Gegenspieler möglich. Es wurden erstmalig ausführliche Versuche zur Parasitierung der Kleider- und Pelzmotte, insbesondere durch Eiaparasitoide der Gattung Trichogramma, durchgeführt. Für die braconide Schlupfwespe Apanteles carpatus wurde eine Zucht- und Freilassungsmethode entwickelt. Sie kann nun als neuer Nützlinge gegen textilschädigende Mottenlarven eingesetzt werden. Eine natürliche Parasitierung textilschädigender Motten durch Eiparasitoide ist bislang nicht nachgewiesen worden. Die Tineiden erwiesen sich im Laborversuch für Trichogramma als gut geeignete Wirte. Hinsichtlich der praktischen Anwendung von Eiparasitoiden der Gattung Trichogramma konnte aus einer Auswahl von 29 Arten und Stämmen aus einer Laborzucht mit T. piceum (Stamm: PIC M 91) eine besonders geeignete Art selektiert werden. Dieser Stamm zeigte die höchste Parasitierungsrate mit über 80 Eiern bei Temperaturen von 20-25°C und einer Lebensdauer von bis zu 17 Tagen. Im Präferenztest wurden sowohl Eier der Kleidermotte als auch der Getreidemotte, dem Massenzuchtwirt, von allen Stämmen mit Abstand am besten parasitiert. Das Geschlechterverhältnis von T. piceum lag bei über 80%. Der untersuchte Stamm von Apanteles carpatus zeigte bei 25°C eine durchschnittliche Nachkommenzahl von 55 pro Weibchen. Die Parasitoide erreichten jedoch nur unter optimalen Bedingungen eine Lebensdauer von bis zu 14 Tagen. In den Käfigversuchen ohne zusätzliche Nahrungsquellen wurden die Tiere nicht älter als 4 Tage. Es war nicht möglich, für A. carpatus Ersatzwirte für eine Massenzucht zu finden, da sie offensichtlich auf Tineiden spezialisiert sind, jedoch konnte ein Zuchtsystem mit Kleidermotten als Zuchtwirte etabliert werden. Die ausgewählten Trichogramma-Arten wurden in Käfigversuchen ausführlich untersucht und im Hinblick auf ihre Suchleistung auf verschiedenen Stoffoberflächen geprüft. Es wurde festgestellt, dass die getesteten Arten sehr unterschiedlich geeignet sind, um Textilien nach Eiern abzusuchen. Die Arten T. evanescens (Stamm: Lager) und T. piceum (PIC M 91) erwiesen sich als in der Suchleistung als am besten geeignet. Im Vergleich dazu zeigte T. cacoeciae (CAC D 90 O) sehr wenig Suchleistugsvermögen auf Textilien. Die geeigneten Arten durchdrangen außer verschiedenen Textilien auch grobe Schafwolle bis zu 0,4 m vom Freilassungsort. Das Ködern von Larvalparasitoiden von tineiden Motten im Freiland erwies sich als nicht erfolgreich. Trotzdem in der Literatur eine Reihe parasitoider Hymenopteren als Gegenspieler von Tineiden beschrieben sind und in Innenräumen beobachtet wurden, war es nicht möglich, weitere freilebende Arten zu ködern. Sowohl für das Ködern im Freiland als auch für die Rückköderung in Lagern wurden Ködermethoden getestet und optimiert. Nebenwirkungstests haben ergeben, dass die Nützlinge ergänzend zum Einsatz von Niem-Präparaten an schlecht zugänglichen Befallsstellen eingesetzt werden können. Ebenso wurde ermittelt, dass eine Kombination des Nützlingseinsatzes mit Repellents möglich ist. Bei zu hoher Konzentration der Wirkstoffe, den reinen Niem-Öl und konzentriertem Lavendel-Öl, in geschlossenen Glaskäfigen, wurden starke Nebenwirkungen auf Trichogramma festgestellt. In größerem Raumvolumen oder geringerer Dosierung der Wirkstoffe parasitierte Trichogramma allerdings auch Ködereier, die sich auf Niem-behandeltem Stoff befanden. Erste Freilassungsversuche in der Praxis ergaben unterschiedliche Erfolge. Nach einer Freilassung von Apanteles carpatus in einem Wohnhaus, das mit Schafwolle gedämmt wurde, reduzierte sich Fang von adulten Motten auf Pheromon-Klebfallen deutlich. In einem Textillager hingegen war es mit einer einmaligen Freilassung jedoch nicht möglich, die Gegenspieler zu etablieren und den Mottenbefall zu kontrollieren. Die mehrwöchige Freilassung von Trichogramma in einem Textillager konnte dazu beitragen, einen Pelzmottenbefall zu reduzieren. Hier zeigten sich Möglichkeiten und Grenzen des Einsatzes von parasitoiden Schlupfwespen gegen Textilmotten gleichermaßen.
