The gene encoding an alkaline active xylanase of Bacillus halodurans S7, containing an open reading frame of 1188 nucleotides encoding 396 amino acids, was cloned and expressed in Escherchia coli. On the basis of sequence similarity, possible -10 and -35, ribosome binding, and transcription terminator regions were identified. Analysis of the deduced amino acid sequence revealed that the protein wa
In the second of two papers, the atmospheric polybrominated diphenyl ethers (PBDE) deposition (wet and dry) at a municipal solid waste incineration (MSW) plant with electronics recycling is compared with that at an industrial urban reference site (URS) producing asphalt and concrete. Results of BDE209 and SigmaPBDE excluding BDE209 as representatives of "new" vs. "old" PBDEs are presented. Volume
We have previously reported a large Danish pedigree with autosomal dominant frontotemporal dementia (FTD) linked to chromosome 3 (FTD3). Here we identify a mutation in CHMP2B, encoding a component of the endosomal ESCRTIII complex, and show that it results in aberrant mRNA splicing in tissue samples from affected members of this family. We also describe an additional missense mutation in an unrela
During the last few years the home care services have had to face an increased responsibility for medical tasks. A study in the city of Malmö in 1993, repeated in 1998, shows that 95% of the health care assistants are engaged in the administration of medication. The studies demonstrate that health care assistants have inadequate knowledge not only about medicines and their administration but also
In order to assess the influence of severe hypoglycemia on local cerebral blood flow (1-CBF) artificially ventilated rats, maintained on 70% N2O, were injected with insulin to provide either an EEG pattern of slow-wave polyspikes, or cessation of spontaneous EEG activity for 5, 15 or 30 min ("coma"). In other animals, glucose was injected at the end of a 30 min period of "coma" and 1-CBF was measu
This paper describes the deformations caused by stress and humidity interaction, mechano-sorption, in the cross grain directions of wood and the relaxation or accumulation of internal stresses caused by these deformations. Long-term tests on small clear specimens in cyclic climates with both tensile and compressive loads were carried out. The development of internal stresses in timber was measured
Popular Abstract in Swedish En kombination av laminära flöden i mikrofabricerade kanaler och akustiska krafter genererade i stående ultraljudsvågor erbjuder nya möjligheter för avancerad partikel- och cellhantering i både lab-on-a-chip-system och applikationer med högre kapacitetskrav. Akustisk partikelhantering kan användas exempelvis för att separera, tvätta, sortera, låsa fast och distribuera pThe combination of laminar flows in microfabricated channels and acoustic forces induced in ultrasonic standing wave fields offers new possibilities for advanced particle and cell manipulation in lab-on-a-chip applications as well as in relatively high throughput applications. Acoustic particle manipulation systems can be used e.g. to separate, wash, sort, trap or distribute particles in microflui
Rapport från ett symposium ingående i rikskonferensen i didaktik planerat till 13 - 15 maj 1993.
Complement analysis in the clinic is usually associated with the quantification of C3 and C4, measurement of C1-inhibitor and screening for complement activity. These analyses have been available in routine diagnostic laboratories for decades. In recent years, however, the field of complement analysis has expanded considerably, with the introduction of novel assays to detect complement activation
Background: Home mechanical ventilation (HMV) and long-term oxygen therapy (LTOT) are the two treatment alternatives when treating respiratory insufficiency in patients with kyphoscoliosis. We aimed to study the effect on survival with regard to HMV or LTOT alone in patients with respiratory insufficiency due to kyphoscoliosis. Methods: Swedish patients with nonparalytic kyphoscoliosis (ie, scolio
Platinum and other nobel metals have been found to catalyze the complete oxidation of sucrose and other sugars by vanadium(IV) in acid environments. As the redox potential of vanadium(IV)/vanadium(III) differs substantially from that of dioxygen/water, it might be possible to use this reaction to construct a redox type of fuel cell. In the present paper, the requirements on the catalyst are discus
Background: Foods with a low glycemic index are increasingly being acknowledged as beneficial in relation to the insulin resistance syndrome. Certain organic acids can lower the glycemic index of bread products. However, the possible effect of acids in fermented milk products on the glycemic index and on insulinemic characteristics has not been addressed. The metabolic effects of fermented milk or
The mechanical properties of the aorta play a major role in the regulation of blood pressure and cardiac performance. The effect of sympathetic stimulation on the mechanical properties of the human abdominal aorta was studied in 19 healthy volunteers, divided into young (25 +/- 2 years) and elderly individuals (69 +/- 2 years) of both sexes. A non-invasive ultrasonic echo-tracking system for measu
It has been suggested that the increase in the number of Hox genes may have been one of the key events in vertebrate evolution. Invertebrates have one Hox cluster, while mammals have four. Interestingly, the number of Hox gene clusters is greater in the teleost fishes, zebrafish and medaka, than in mouse and human. The greater number of Hox clusters in the teleosts suggests that Hox gene duplicati
