Reinnervation of syngeneic pancreatico-duodenal grafts in rats

BACKGROUND: Knowledge on the reinnervation of transplanted organs is scarce, and the aim of the study was therefore to evaluate to what degree syngeneic pancreas grafts were reinnervated in rats. METHODS: Syngeneic pancreatico-duodenal transplantations were performed in normoglycemic Wistar-Furth rats. Native and transplanted pancreas and duodenum were removed 4 or 40 weeks after implantation, and

This thesis deals with the development of the DP (the Determiner Phrase) in bilingual first (2L1) and in adult second (L2) language acquisition of French. The thesis shows that the children and the adult Swedish learners acquire syntactic categories differently: the children follow a structural economy principle in positing as small categories as possible (Rizzi, 1998). The adult learners aim to

Mutation in the cystatin C gene causes hereditary brain hemorrhage

Hereditary cystatin C amyloid angiopathy (HCCAA) is an autosomal dominant disorder leading to massive brain hemorrhage and death in young adults (Jensson et al., 1987). A variant of a potent inhibitor of cysteine proteinases, cystatin C (Barrett et al., 1984), is deposited as amyloid fibrils in the cerebral arteries of the patients (Ghiso et al., 1986). We have used the full length cystatin C cDNA

Cdk6 blocks myeloid differentiation by interfering with Runx1 DNA binding and Runx1-C/EBP alpha interaction

Interactions between the cell cycle machinery and transcription factors play a central role in coordinating terminal differentiation and proliferation arrest. We here show that cyclin-dependent kinase 6 (Cdk6) is specifically expressed in proliferating hematopoietic progenitor cells, and that Cdk6 inhibits transcriptional activation by Runx1, but not C/ EBP alpha or PU. 1. Cdk6 inhibits Runx1 acti

Diabetic children and their parents: personality correlates of metabolic control

Test measures of field-dependence-independence and impulsiveness-control were obtained from two groups of diabetic children and their parents, the children being in optimal (O, n = 12) or poor (P. n = 27) metabolic control and, according to the judgment of clinicians, showing optimal or poor psychological adaptation. Children of the O-group scored lower in impulsiveness and higher in realistic fun

Free cytosolic calcium during spontaneous contractions in smooth muscle of the guinea-pig mesotubarium

The free intracellular calcium ion concentration ([Ca2+]i) was measured simultaneously with isometric force in strips of guinea-pig mesotubarium using the Fura-2 technique. During the relaxed period (5-15 min) between spontaneous contractions [Ca2+]i continues to decrease after full mechanical relaxation to reach a minimal level of 86 +/- 8 nM (n = 9) just before the start of the next contraction.

Beräkning av fukttillstånd : enkel metod för praktiker

Med metoden kan fuktflödet genom, och relativa fuktighetens fördelning i en konstruktion beräknas. Metoden kan tillämpas på konstruktioner som består av upp till tre materialskikt. Materialdata redovisas för betong, bruk, makadam, dräneringsgrus, lättbetong, tegel, trä, spånskiva och golvmattor.

Attraction of the larval predator Elater ferrugineus to the sex pheromone of its prey, Osmoderma eremita and its implication for conservation biology

Elater ferrugineus is a threatened click beetle inhabiting old hollow trees. Its larvae consume larvae of other saproxylic insects including the threatened scarab beetle Osmoderma eremita. Recently, (R)-(+)-gamma-decalactone was identified as a male-produced sex pheromone of O. eremita. Here we present evidence that E. ferrugineus adults use this odor as a kairomone for location of their prey. In

Soft shadow volumes for ray tracing

We present a new, fast algorithm for rendering physically-based soft shadows in ray tracing-based renderers. Our method replaces the hundreds of shadow rays commonly used in stochastic ray tracers with a single shadow ray and a local reconstruction of the visibility function. Compared to tracing the shadow rays, our algorithm produces exactly the same image while executing one to two orders of mag

Quantification method of human hemoglobin adducts from hexahydrophthalic anhydride and methylhexahydrophthalic anhydride

A method was developed for the determination of human hemoglobin (Hb) adducts from hexahydrophthalic anhydride (HHPA) and methylhexahydrophthalic anhydride (MHHPA). The procedure includes lysis of erythrocytes, dialysis of the Hb-solution followed by acid hydrolysis. The released hexahydrophthalic (HHP) acid and methylhexahydrophthalic (MHHP) acid were purified using a combined liquid-liquid and s

The inhibition of ammonium uptake in excised birch (Betula pendula) roots by batatasin-III.

In northern Sweden, plants growing in association with the clonal dwarf shrub Empetrum hermaphroditum usually exhibit limited growth and are N-depleted. Previous studies suggest that this negative effect by E. hermaphroditum may be explained, at least in part, by the release of phenolic compounds, particularly the dihydrostilbene, batatasin-III from foliage to soil. In the present work, we investi
