In vivo long-term durability of the bond to dentin using two adhesive systems.

Purpose: The objective of this work was to evaluate the in vivo long-term durability of bond strength and morphological appearance of interfaces between dentin and two adhesive systems.

Materials And Methods: Class V cavities were prepared on the facial surfaces of 6 intact teeth of a monkey, and restored with Unifil Bond/Unifil F and Fuji Bond LC/Clearfil AP-X. One year later, 10 other teeth were restored with the same materials and the monkey was sacrificed after 24 hours.

Augmentation of immune cell activity against tumor cells by Rauwolfia radix.

In this study, we investigated the effect of Rauwolfia radix on heat shock protein (HSP) 70 expression and cytotoxicity against tumor cells in activated human T cells. When activated T cells were cultured with Rauwolfia radix for 18 h, HSP70 expression after heat shock was remarkably increased, and cytotoxicity against T98G tumor cells was augmented. Moreover, Rauwolfia radix also enhanced the cytotoxicity of heat shocked activated T cells against Molt-4 and T98G tumor cells.

Efp targets 14-3-3 sigma for proteolysis and promotes breast tumour growth.

Oestrogen exerts its influence on target organs through activating oestrogen receptors (ERs) and regulating downstream genes by means of their oestrogen-responsive elements. Efp, a target gene product of ER alpha, is a member of the RING-finger B-box coiled-coil (RBCC) motif family. Efp is predominantly expressed in various female organs as well as in breast cancers, and is thought to be essential for oestrogen-dependent cell proliferation and organ development Efp-disrupted mice display underdeveloped uteri and reduced oestrogen responsiveness.

Increased plasma morphine metabolites in terminally ill cancer patients with delirium: an intra-individual comparison.

Delirium often causes severe distress for terminally ill cancer patients, and treatment of underlying pathologies is important to achieve symptom alleviation. Although accumulation of morphine metabolites may play an important role in development of delirium, empirical findings are conflicting due to a large inter-individual variation in morphine-related concentrations. To explore intra-individual changes of morphine metabolite concentrations before and after occurrence of terminal delirium, a prospective observational study was performed on terminally ill cancer patients.

Interaction of phytoestrogens with estrogen receptors alpha and beta (II).

We investigated the estrogenic activities of isoflavone derivatives in competition binding assays with human estrogen receptor (hER) alpha or hER beta protein, and in a gene expression assay using a yeast system. Coumestrol binds as strongly as 17beta-estradiol to both hERs. Biochanin A, 5-OMe-genistein, formononetin, and tectorigenin bind well to hER beta, but significant binding to hER alpha is only observed with 5-OMe-genistein, formononetin and tectorigenin.
