BACKGROUND: Gastrin and cholecystokinin (CCK) are thought to exert trophic effects on the gastrointestinal tract and pancreas. Two types of receptors have been cloned, CCK-A and CCK-B/ gastrin. We have examined the occurrence of CCK-A and CCK-B receptor mRNA in the brain, digestive tract, pancreas, and kidney of the rat and man by Northern blot and reverse transcribed polymerase chain reaction (RT

In osteoarthritis (OA), cartilage and bone fragments have been described within the synovial tissue which are surrounded by synovial cells (i.e. detritus synovitis). These cells appear to attach actively to the cartilage and bone fragments. In rheumatoid arthritis (RA), on the other hand, synovial fibroblasts (SF) have also been shown to be localized at sites of invasion into cartilage and bone an

Bulgarian apico-alveolar stops and Swedish dorsovelar stops are palatalized when adjacent to front vowels. An X-ray motion film study of these assimilations (part of an ongoing investigation of the temporal organisation of coarticulation and assimilation) is presented. Two issues are examined, extrinsic vs intrinsic production of assimilation and feature spreading vs. coproduction. The articulator

On Sufi gatherings in London and the impact of a visiting shaykh.

This paper presents theory and algorithms for covariance analysis and stochastic realization without any minimality condition imposed. Also without any minimality conditions, we show that several properties of covariance factorization and positive realness hold. The results are significant for validation in system identification of state-space models from finite input-output sequences. Using the R

This chapter investigates the interaction between monuments, city-scape and viewers. It targets representation of movement and arrest in the public narrative reliefs of Imperial Rome. A leading idea is that movement in the image was consciously designed to connect with movement in front of it – to attract and guide the viewers’ move and gaze. As a consequence, the nature of the monument and its im

Is the Armenian Genocide a strictly historical matter? If that is the case, why is it still a topical issue, capable of causing diplomatic rows and heated debates? The short answer would be that the century old Armenian Genocide is much more than a historical question. It emerged as a political dilemma on the international arena at the San Stefano peace conference in 1878 and has remained as such

Wnt-signaling is one of the most abundant pathways involved in processes such as cell-proliferation, -polarity, and -differentiation. Altered Wnt-signaling has been linked with several neurodevelopmental disorders including attention-deficit/hyperactivity disorder (ADHD) as well as with cognitive functions, learning and memory. Particularly, lipoprotein receptor-related protein 5 (LRP5) or LRP6 co

The material evidence left from the cult of Sabazios is meagre, apart from sculpted bronze hands dating to the Roman Empire. The hand is held in a certain pose, the so-called benedictio Latina gesture, and the hand was often covered with depictions of various objects and symbols. The bronze hands were probably attached to staffs and carried around in processions. This practice most likely spread v

A computer program called IDAC-CAD2VOX has been constructed to create geometry input files from CAD drawings for the Monte Carlo simulation program MCNP. The ICRP reference phantoms are incorporated into the CAD drawings to estimate organ doses and the effective dose. The program is applied to a CAD drawing of a house and a 2D drawing of a radiation protection bunker. The created MCNP geometry wa

Laminar burning velocities of hydrocarbon blends of relevance to natural gas combustion, with addition of 0, 10, 35 and 50% hydrogen, were measured using the heat flux method. Hydrocarbon blends were methane (80%)/ethane (20%), methane (80%)/propane (20%) and methane (80%)/ethane (10%)/propane (10%), and in addition experiments were performed using pure methane as a fuel. For the first time it was
