Structure and expression of the human cystatin C gene

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

Human papilloma virus in skin, mouth and uterine cervix in female renal transplant recipients with or without a history of cutaneous squamous cell carcinoma

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

Profiling of internalizing tumor-associated antigens on breast and pancreatic cancer cells by reversed genomics

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

Patients with laxity of the distal radioulnar joint after distal radial fractures have impaired function, but no loss of strength

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 for the refinement of surface structure in LEED

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

Genetic characterization of malignant melanoma and breast cancer

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

A Model Based Approach to Robustness Analysis and Optimisation of Chromatography Processes

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

The Effect of Transfer Port Geometry on Scavenge Flow Velocities At High Engine Speed

2-D LDV measurements were performed on two different cylinder designs in a fired two-stroke engine running with wide-open throttle at 9000 rpm. The cylinders examined were one with open transfer channels and one with cup handle transfer channels. Optical access to the cylinder was achieved by removing the silencer and thereby gain optical access through the exhaust port. No addition of seeding wa

Studies on Neuropsychiatric Manifestations and Genetic Factors in Systemic Lupus Erythematosus

Background: Systemic Lupus Erythematosus (SLE) is an autoimmune disease encompassing a wide range of symptoms that can emanate from pathology in virtually any organ system. Severe SLE includes involvement of the central nervous system and kidneys. One of the hallmarks of the disease is a multitude of autoantibodies, indicating a breakdown in self tolerance. The corresponding antigens have been fou

"Distributed proton radiation therapy'' - A new concept for advanced competence support

The increased interest in high precision radiation therapy is to a large extent driven by the potential of modern imaging technology. The aim of this project was to analyse how an expensive proton facility best could support a multi-centre health care system. We have developed a model for distributed expert collaboration where all clinical experts will work close to their patients in regional cent

Compression Ratio Influence on Maximum Load of a Natural Gas Fueled HCCI Engine

This paper discusses the compression ratio influence on maximum load of a Natural Gas HCCI engine. A modified Volvo TD100 truck engine is controlled in a closed-loop fashion by enriching the Natural Gas mixture with Hydrogen. The first section of the paper illustrates and discusses the potential of using hydrogen enrichment of natural gas to control combustion timing. Cylinder pressure is used as

Staphylococcal enterotoxin H induces V alpha-specific expansion of T cells.

Staphylococcal enterotoxin H (SEH) is a bacterial superantigen secreted by Staphylococcus aureus. Superantigens are presented on the MHC class II and activate large amounts of T cells by cross-linking APC and T cells. In this study, RT-PCR was used to show that SEH stimulates human T cells via the V domain of TCR, in particular V10 (TRAV27), while no TCR V-specific expansion was seen. This is in s
