Ein transgenes Mausmodell zur Untersuchung des Einflusses von Matrix Metalloproteinase-2 und -14 auf die Leber

MMP-2 and MMP-14 process extracellular matrix proteins,cytokines, growth factors and adhesion molecules to generatefragments with enhanced or reduced biological activity.In this study, a vectorsystem was developed for theconditional expression of MMP-2 and MMP-14 in the liver oftransgenic mice. For this vectorsystem the murine albuminpromotor was chosen together with the cre/lox system toachieve an inducible MMP-expression in the liver.Only one of the MMP-14 transgenic lines expressed highamounts of active MMP-14 protein after recombination of thelox-P sites. In these mice MMP-14 was able to activate MMP-2and MMP-13 in vivo. However, none of the livers of MMP-14overexpressing mice showed no differences in liverweight,amount of extracellular matrixproteins and rate ofproliferation, apoptosis and tumor-induction when comparedto the liver of wildtype mice.On the other hand overexpression of MMP-2 was embryoniclethal in all MMP-2 transgenic lines. After crossing theMMP-2 transgenic mice with cre deleter mice, a cre mediatedrecombination could be shown at day 6.5 post coitum (pc).Some of the double transgenic embryos of one of thetransgenic lines had severe deformations of the head,especially of the telencephalon and the mesencephalon.It could be shown in this study that disregulation of MMP-2in early embryonic development is lethal but anoverexpression of MMP-14 has no influence on the embryonicdevelopment or the homeostasis of the adult liver.With this conditional vectorsystem it is to possible studythe influnce of MMP-2 and MMP-14 on fibrogenesis,regeneration and tumorgenesis in the liver of mice.

(Table 2) Production parameters of phytoplankton and some associated parameters in the area of the Titanic Polygon

Studies were carried out mostly in the area of RMS Titanic wreck site (41°44'N, 49°57'W) located above the continental slope and the south of the Grand Banks of Newfoundland. In a period from 18.06 to 24.09.2001 five surveys of production characteristics of surface phytoplankton were conducted over 5-9 days. Mean values of these characteristics obtained during the surveys were 9.2-11.7 mg C/m**3 per day for primary production (C_phs), 0.102-0.188 mg/m**3 for chlorophyll a (C_chls), and 4.44-7.42 mg C/mg chl. a per hour for assimilation number (AN). The main reason for low C_phs variability was a significant inverse relationship (R=-0.66) between AN and C_chls found over the research area. When cold shelf waters dominated in the area (27.07 to 19.08.2001), C_chls values for the slope region (0.125+/-0.031 µg/l) and for the outer shelf (0.130+/-0.040 µg/l) were similar. During strengthening of influence of warmer slope waters within area (from 29.08 to 13.09.2001), C_chls concentration within surface waters of the outer shelf was 0.152+/-0.039 µg/l and exceeded one for the slope region (0.094+/-0.004 µg/l) by factor 1.6. Against the background of low Cchls values, the High values of integral primary production in the water column (510-1010 mg C/m**2 per day) at low C_chls values measured within the area were determined both by high assimilation activity of phytoplankton and by the deep (30-40 m) maximum of primary production. Main reasons for formation of such a maximum were high chlorophyll concentration within the layer of the deep chlorophyll maximum (up to 0.5-2.5 µg/l) and in the relatively high solar irradiance within this layer varying from 1.4 to 8.6% of subsurface PAR.

Suspended matter in waters of the Kem' River estuary (white Sea) and its composition in July-August 2003 and 2002

On the base of detailed studies in the Keret' and Kem' estuaries (Karelian coast of the White Sea) in 2000-2003 a comparative analysis has been carried out. It includes: salinity and freshening of the water column, variations of suspended matter concentration and its chemical composition, current velocity and zooplankton species composition during flood- and ebb tides.

Abundance of mesozooplankton during the long-tern mesozooplankton analysis in Sevastopol Bay from 1976 to 2003

The present dataset includes results of analysis of 227 zooplankton samples taken in and off the Sevastopol Bay in the Black Sea in 1976, 1979-1980, 1989-1990, 1995-1996 and 2002-2003. Exact coordinates for stations 1, 4, 5 and 6 are unknown and were calculated using Google-earth program. Data on Ctenophora Mnemiopsis leidyi and Beroe ovata are not included. Juday net: Vertical tows of a Juday net, with mouth area 0.1 m**2, mesh size 150µm. Tows were performed at layers. Towing speed: about 0.5 m/s. Samples were preserved by a 4% formaldehyde sea water buffered solution. Sampling volume was estimated by multiplying the mouth area with the wire length. The collected material was analysed using the method of portions (Yashnov, 1939). Samples were brought to volume of 50 - 100 ml depending upon zooplankton density and mixed intensively until all organisms were distributed randomly in the sample volume. After that 1 ml of sample was taken by calibrated Stempel-pipette. This operation was produced twice. If divergence between two examined subsamples was more than 30% one more subsample was examined. Large (> 1 mm body length) and not abundant species were calculated in 1/2, 1/4, 1/8, 1/16 or 1/32 part of sample. Counting and measuring of organisms were made in the Bogorov chamber under the stereomicroscope to the lowest taxon possible. Number of organisms per sample was calculated as simple average of two subsamples meanings multiplied on subsample volume. Total abundance of mesozooplankton was calculated as sum of taxon-specific abundances and total abundance of Copepods was calculated as sum of copepods taxon-specific abundances.

Quintus Curtius before his sources: the episode of Alexander and the Scythians on the Tanais

Quintus Curtius found in his sources a speech where a Scythian censured Alexander, followed by the King’s reply. Curtius drastically abridged this second discourse in order to highlight the criticism of the Macedonian. The Scythian’s words have a striking rhetorical language and some allusions taken from Greek literature, in addition to possible indirect references to Caligula. Curtius declares that he follows his source word-for-word aiming to justify these inconsistencies, but also trying to hide the manipulations he has done to achieve his own narrative purposes.

Sesamoids of the metatarsophalangeal joint of the big toe: a sistematic review

Abstract: The first metatarsal sesamoid bones are not always taken into consideration when making a diagnosis, in pathologies that affect the region of the first metatarsal head. This is due to the insufficient knowledge of all the pathologies that can affect the sesamoids and the relative little incidence that they have. With the increment of sports activities, in particular the running, increasingly affects of the symptoms concerning this region are observed. Methods: A literature search was performed in 5 databases (Medline, PubMed, Scopus, Cochrane Library and BUCEA). The terms included in the search were: sesamoids, anatomy, biomechanics, sesamoids review and sesamoids pathology. In the initial search articles with no more than 10 years, only humans and revision texts are considered. Results: 24 articles were selected and include different pathologies with diagnosis using imaging tests and treatments, both conservative and surgical; as well as aspects from the biomechanics of the metatarsal-sesamoid joint. Conclusion: Sesamoids due of his anatomy, topography and function can be involved in a lot of pathologies; with similar signs and symptoms that can confuse the podiatry when he has to make a correct diagnosis or treatment.
