Collagen VI, a microfibrillar protein found in virtually all connective tissues, is composed of three distinct subunits, alpha 1(VI), alpha 2(VI), and alpha 3(VI), which associate intracellularly to form triple helical heterotrimeric monomers then dimers and tetramers. The secreted tetramers associate end-to-end to form beaded microfibrils. Although the basic steps in assembly and the structure of

Stem cells are unspecialized cells able to divide and produce copies of themselves and having the potential to differentiate, i.e. to produce other cell types in the body. Because of the latter ability, the scientists investigate their possible use in regenerative medicine. Especially embryonic stem cells have huge therapeutic potential because they can give rise to every cell type in the body as

The monotremes, the duck-billed platypus and the echidnas, are characterized by a number of unique morphological characteristics, which have led to the common belief that they represent the living survivors of an ancestral stock of mammals. Analysis of new data from the complete mitochondrial (mt) genomes of a second monotreme, the spiny anteater. and another marsupial, the wombat. yielded clear s

Objective. A disease-modifying osteoarthritic drug (DMOAD) should interfere with the cartilage breakdown observed and improve symptoms or prevent deterioration of the patient's clinical condition. We propose a composite index including structural and symptomatic variables of osteoarthritis (OA) as criteria for being considered a candidate for total joint replacement as an endpoint in clinical tria

To prospectively study the prevalence of Lyme arthritis, 100 consecutive patients referred to a rheumatology out-patient clinic and 115 patients with a classified rheumatological disease were included. Individuals seropositive for antibody against the Borrelia burgdorferi sensu lato complex were examined for clinical signs or a history of Lyme borreliosis. Positive titres against B. burgdorferi s.

Objective: Five double-blind, randomized, saline-controlled trials (RCTs) were included in the United States marketing application for an intra-articular hyaluronan (IA-HA) product for the treatment of osteoarthritis (OA) of the knee. We report an integrated analysis of the primary Case Report Form (CRF) data from these trials. Method. Trials were similar in design, patient population and outcome

OBJECTIVE: To compare the capacity of transvaginal Doppler ultrasound examination with that of gray scale sonography as an aid in distinguishing benign and malignant pelvic tumors of suspected adnexal origin. STUDY DESIGN: One hundred and fifty-one women scheduled for laparotomy or laparoscopic surgery because of a pelvic mass of suspected adnexal origin underwent ultrasound examination including

Background Low competence levels among nursing staff have been associated with lower quality of elderly care. However, interventions aimed at improving nursing staff competence have not always been evaluated for their possible impact on the quality of elderly care. An educational intervention in the form of a workplace “toolbox” was shown to have positive effects on nursing staff competence and wo

Aims/hypothesis. Fat accumulation in the liver has been shown to be closely correlated with hepatic insulin resistance and features of insulin resistance, also independently of body weight. It remains to be established how fat in the liver correlates with that in other depots, and whether any association differs between men and women. Methods. Liver fat (assessed using proton spectroscopy), intra-

This study reports the outcome of active surveillance in men with PSA screening-detected prostate cancer (PC), and PSA doubling time (PSADT) was evaluated as a predictor of selecting patients to active treatment or surveillance. On December 31, 1994, 10,000 men were randomized to biennial PSA testing. Through to December 2004, a total of 660 men were diagnosed with PC, of whom 270 managed with ini

A graphic method was developed for presentation of the location and extent of the myocardium at risk in patients with acute myocardial infarction (AMI). This method is based on a mathematical processing of ST-segment deviations of standard 12-lead electrocardiogram following the concept of Titomir and Ruttkay-Nedecky in their dipolar electrocardiotopographic method. The center of the location of t

The cystatin C gene (CST3) encodes a low-molecular-weight cysteine proteinase inhibitor belonging to family II of the cystatin super family and is mutated in cases of hereditary cystatin C amyloid angiopathy (HCCAA). CST3, which along with other family II cystatin genes is a member of the cystatin gene family, has been assigned to chromosome 20. To investigate the genomic organization on chromosom

Background: The national programs for the harmonization of hemoglobin (Hb)A(1c) measurements in the US [National Glycohemoglobin Standardization Program (NGSP)], Japan [Japanese Diabetes Society (JDS)/Japanese Society of Clinical Chemistry (JSCC)], and Sweden are based on different designated comparison methods (DCMs). The future basis for international standardization will be the reference system

Cladribine has single-drug activity in acute myeloid leukaemia (AML), and may enhance the formation of the active metabolite (ara-CTP) of cytosine arabinoside (ara-C). To evaluate the feasibility of adding intermittent cladribine to intermediate-dose ara-C (1 g/m(2)/2 h) b.i.d. for 4 d with idarubicin (CCI), we performed a 2:1 randomized phase II trial in AML patients aged over 60 years. Primary e

A distillation unit has been designed for a capacity of 73 t/h of condensate and for at least 90% recovery of the contaminating organics. This unit consists of three columns: a primary stripper to remove volatile organics and two upgrading columns to purify the methanol and furfural byproducts. Three different energy-saving alternatives for satisfying the energy requirements have been studied: ut

BACKGROUND: Effective T-cell depletion is a prerequisite for haploidentical peripheral blood progenitor cell (PBPC) transplantation. This study was performed to investigate the performance of magnetic cell sorting–based direct large-scale T-cell depletion, which is an attractive alternative to standard PBPC enrichment procedures. STUDY DESIGN AND METHODS: PBPCs were harvested from 11 human leukoc
