Ergosterol was used as a marker of fungal biomass and 3-hydroxy fatty acids were used as markers of bacterial endotoxin to determine microbial colonisation of building materials by gas chromatography-mass spectrometry. Pieces (0.3-0.5 g) of materials from two water-damaged buildings were hydrolysed to liberate the markers from larger microbial structures; the preparations were then purified, deriv
Bacillus stearothermophilus neopullulanase (NPL) structure was modeled based on Aspergillus oryzae alpha-amylase (TAA) to understand the structure-function relationships of this pullulan hydrolyzing enzyme. The NPL structure seems to consist of a central (alpha/beta)(8) barrel to which the other domains are attached. The immediate surroundings of the NPL catalytic site were found to have very simi
In this paper we present algorithms to compute finite state automata which, given any rational language, recognize the languages of normal words and n-chains. We also show how these automata can be used to compute the Hilbert series and Poincaré series for any algebra with a rational set of leading words of its minimal Gröbner basis.
We performed ultrasonography on 32 athletes complaining of intense pain in a swollen and tender thigh or calf after a contusion or stretching trauma. The ultrasonogram was used to visualize the presence and size of a suspected hematoma. The findings included the following: 7 patients with a circumscribed, anechoic lesion compatible with a liquefied hematoma; 10 patients with a circumscribed lesion
Cyclic nucleotide phosphodiesterase (PDE) 3B plays an important role in the antilipolytic action of insulin and, thereby, the release of fatty acids from adipocytes. Increased concentrations of circulating fatty acids as a result of elevated or unrestrained lipolysis cause insulin resistance. The lipolytic action of tumor necrosis factor (TNF)-alpha is thought to be one of the mechanisms by which
The structural organization of the gene for the human cysteine-proteinase inhibitor cystatin C was studied. Restriction-endonuclease digests of human genomic DNA hybridized with human cystatin C cDNA and genomic probes produced patterns consistent with a single cystatin C gene and, also, the presence of six closely related sequences in the human genome. A 30 kb restriction map covering the genomic
Some human papilloma viruses are thought to be associated with skin cancer. In this pilot study, 21 female renal transplant carriers, 10 with a history of skin squamous cell carcinoma and 11 without, together with 9 age-matched healthy women were investigated for human papilloma virus DNA in sun-exposed (forehead) and less sun-exposed (buttock) skin, mouth and uterine cervix. Paraffin-embedded tum
Human antibodies directed towards functionally associated tumor antigens have great potentials as adjuvant treatment in cancer therapy. Here we describe an efficient subtractive approach to select single chain Fv (scFv) antibodies, specifically binding to unknown rapidly internalizing tumor-associated antigens (TAA) on human breast and pancreatic carcinoma cell lines. After re-engineering the scFv
Laxity of the distal radioulnar (DRU) joint after distal radial fractures has a worse general outcome in patients before the usual age for development of osteoporosis. The hypothesis for this study was that patients with laxity also have less strength during supination and pronation. An apparatus for measuring strength in supination and pronation was constructed and validated. 20 patients were cho
A simple and effective procedure is described for the determination of the best-fit parameters of a given model of a surface structure by analysis of low energy electron diffraction (LEED) intensities. The procedure involves a nonlinear minimisation of chi(2) for the comparison of experimental and calculated intensities as a function of the parameters of the model structure. The minimisation is ca
Malignant melanoma and breast cancer are common malignant diseases characterized by considerable heterogeneity with respect to genetics, histopathology, biology and clinical course. In breast cancer, two major susceptibility genes have been identified, BRCA1 and BRCA2, which account for a significant proportion of high-risk breast cancer families. Breast tumors arising in BRCA1 or BRCA2 mutation c
Popular Abstract in Swedish Kostnaden för utveckling och validering av produktionsanläggningar är idag ett stort problem för farmaceutisk industri. Valideringen innebär normalt en stor experimentell arbetsinsats. Den stora mängden experimentellt arbete innebär att det utvecklas färre läkemedel och till högre kostnad idag jämfört med tidigare. FDA har uppmärksammat detta i sitt PAT initiativ. En mOne of the major issues in the pharmaceutical industry today is the cost of development and validation of the production of the active pharmaceutical ingredients. The development, optimization and validation of a production plant have been dominated by an extensive experimental approach. The large amount of experimental work and reluctance for changing existing processes has caused the pharmaceut
