Decreased metastatic spread in mice homozygous for a null allele of the cystatin C protease inhibitor gene

AIMS: Increased or altered activities of cysteine proteases have been implicated in serious human disorders such as cancer, rheumatoid arthritis, sepsis, and osteoporosis. To improve the current knowledge of the regulatory role of a major mammalian cysteine protease inhibitor, cystatin C, in such disease processes, a cystatin C deficient mouse was generated and characterized. METHODS: The mouse cy

IL-2 overcomes the unresponsiveness but fails to reverse the regulatory function of antigen-induced T regulatory cells

Intranasal administration of peptide Acl-9[4Y], based on the N-terminal epitope of myelin basic protein, can induce CD4(+) T cell tolerance, and suppress experimental autoimmune encephalomyelitis induction. The peptide-induced regulatory T (PI-T-Reg) cells failed to produce IL-2, but expressed IL-10 in response to Ag and could suppress naive T cell responses in vitro. Analysis of Jak-STAT signalin

Revision of the CEAP classification for chronic venous disorders: Consensus statement

The CEAP classification for chronic venous disorders (CVD) was developed in 1994 by an international ad hoc committee of the American Venous Forum, endorsed by the Society for Vascular Surgery, and incorporated into "Reporting Standards in Venous Disease" in 1995. Today most published clinical papers on CVD use all or portions of CEAP. Rather than have it stand as a static classification system, a

Development of educational image databases and e-books for medical physics training

Medical physics education and training requires the use of extensive imaging material and specific explanations. These requirements provide an excellent background for application of e-Learning. The EU projects Consortia EMERALD and EMIT developed five volumes of such materials, now used in 65 countries. EMERALD developed e-Learning materials in three areas of medical physics (X-ray diagnostic rad

A numerical investigation of gas flow and heat transfer in proton exchange membrane fuel cells

Gas flow and heat transfer in both cathode and anode channels have been modeled and analyzed for proton exchange membrane fuel cells. The simulated channel consists of a porous electrode layer (anode or cathode), gas flow duct, and solid current collector. The characteristics of gas flow and heat transfer in terms of friction factor and Nusselt number were investigated by a three-dimensional compu

Comparison of Endorette and dilatation and curettage for sampling of the endometrium in women with postmenopausal bleeding

MAIN QUESTION: To compare the diagnostic properties of Endorette and D&C in women with postmenopausal bleeding, to relate the properties to endometrial thickness as measured by ultrasound, and to assess the women's experiences of the two methods. METHODS: In a prospective study, 133 consecutive women with postmenopausal bleeding were examined with transvaginal ultrasound. After measuring the e

Kinematic and kinetic gait analysis in the sagittal plane of trans-femoral amputees before and after special gait re-education.

A special gait-training programme, combining a psychological therapeutic approach with methods in physiotherapy and body awareness, was used to re-educate nine unilateral trans-femoral amputees. All were rehabilitated trauma or tumour amputees with an age of 16-60 years. They had worn prostheses for more than 18 months. The re-education aimed at integrating the prosthesis in normal movements and i

Continuity of the percolation threshold in randomly grown graphs

We consider various models of randomly grown graphs. In these models the vertices and the edges accumulate within time according to certain rules. We study a phase transition in these models along a parameter which refers to the mean life-time of an edge. Although deleting old edges in the uniformly grown graph changes abruptly the properties of the model, we show that some of the macro-characteri

Electrospray ionization mass spectrometry in enzymology: uncovering the mechanisms of two- substrate reactions

The purpose of this review is to draw attention to the use of electrospray ionization mass spectrometry ( ESI-MS) for monitoring the course of enzyme substrate interactions, in the particular case of complex systems in which two substrates participate. The determination and characterization of intra-molecular reactions, especially those that occur in the enzyme active site, is not a trivial task i

Production and physicochemical characterization of acidocin D20079, a bacteriocin produced by Lactobacillus acidophilus DSM 20079

Lactobacillus acidophilus DSM 20079 is the producer of a novel bacteriocin termed acidocin D20079. In this paper, a partial sequence of this peptide is determined, together with data on its secondary structure. A modification of the MRS-growth medium (replacing the detergent Tween 80 with oleic acid), was shown to improve the production level of the peptide by one order of magnitude, as well as to

Stimulated amplification in an astrophysical plasma: An FeII space laser in gas condensation in the vicinity of eta carinae

We consider the conditions necessary for the development of an inverted population among the energy levels of free atoms in a medium exposed to radiation in spectral nonequilibrium. In particular, we focus on monochromatic radiation occurring as a result of an accidental wavelength coincidence between a pumping emission line and a pumped absorption line in two different elements. We examine especi

Antenna protein composition of PS I and PS II in thylakoid sub-domains

Spinach thylakoids were separated into grana core, grana margin, and two different stromal lamella fractions in the absence of detergents. The levels of all light-harvesting chlorophyll a/b-binding (LHC) proteins were determined in all fractions, and were normalised to the amount of Photosystem I (PS I) and Photosystem II (PS II) centres. PS Iβ in the stroma lamellae was found to have a full compl

The ecology of recovery

The current high rate of population declines and attempts to 'manage' their recovery, call for a better understanding of recovery dynamics of populations. In many cases, recovery of a population may primarily be determined by a single life history property or ecological interaction, allowing for straightforward management actions. For example, a generalist predator may prevent the recovery of its

Correlation between overgrowth morphology and optical properties of single self-assembled InP quantum dots

We have studied the early stages of GaInP overgrowth on InP quantum dots (QD's) experimentally and theoretically. A direct correlation between the surface morphology and the optical properties of individual InP QD's is made using scanning tunneling microscopy (STM) and scanning tunneling luminescence. The geometric structure of the islands is further investigated using cross-sectional transmission

Threads and Images : The Use of Scripture in Apophthegmata Patrum

Popular Abstract in Swedish Studien behandlar bibelbruket i den grekiska systematiska samlingen av Apophthegmata Patrum ( kenfädernas tänkespråk). Efter en inledande genomgång av tidigare forskning på biblebruk i allmänhet och det i tänkespråken i synnerhet formuleras undersökningens syfte så: att beskriva hur bibeltexten kontextualiseras, dvs. hur texten infogas i den undervisning och de ideal soThis study is devoted to the use of the Bible in the Greek systematic collection of Apophthegmata Patrum (AP). After an introductory survey of earlier research on the use of Scripture in general, and that of AP in particular, the main purpose of the investigation is formulated: to describe how the Bible text is contextualized, i.e., how the text is integrated with the teachings and ideals in the s
