[Comprehensive geriatric care for frail elderly at home: a feasibility study].

Objective: To evaluate the feasibility of a study on the content and effect of comprehensive geriatric care (CGC) at home for frail elderly.

Method: Case managers invited new CGC patients of one care organization for participation in the study. At two moments, questionnaires were conducted on (social) functioning, quality of life, perceived problems, perceived informal caregiver burden, and self-management.

Over-expression and properties of a purified recombinant Bacillus licheniformis lipase: a comparative report on Bacillus lipases.

The gene coding for an extracellular lipase of Bacillus licheniformis was cloned using PCR techniques. The sequence corresponding to the mature lipase was subcloned into the pET 20b(+) expression vector to construct a recombinant lipase protein containing 6 histidine residues at the C-terminal. High-level expression of the lipase by Escherichia coli cells harbouring the lipase gene-containing expression vector was observed upon induction with IPTG at 30 degrees C.

Interaction of Ap1, Ap2, and Sp1 with the regulatory regions of the human pro-alpha1(I) collagen gene.

In the pro-alpha1(I) collagen gene a number of cis-regulatory elements, which interact with a variety of trans-acting factors, are present in the promoter and first intron. We have undertaken a comprehensive study of Sp1, Ap1, and Ap2 binding in the region spanning -442 to +1697 nt. DNase I footprinting analysis revealed these factors bind with varying affinities to some of the potential sites: Sp1 binds to 16 of 34 potential sites, Ap2 binds to 22 of 40 potential binding sites, and Ap1 binds to its only potential site.

Heterochromatin effects on the frequency and duration of LCR-mediated gene transcription.

Locus control regions (LCRs) are responsible for initiating and maintaining a stable tissue-specific open chromatin structure of a locus. In transgenic mice, LCRs confer high level expression on linked genes independent of position in the mouse genome. Here we show that an incomplete LCR loses this property when integrated into heterochromatic regions.
