Human embryonic stem cells (hESC) are isolated as clusters of cells from the inner cell mass of blastocysts and thus should formally be considered as heterogeneous cell populations. Homogenous hESC cultures can be obtained through subcloning. Here, we report the clonal derivation and characterization of two new hESC lines from the parental cell line SA002 and the previously clonally derived cell l
Unexpected outcomes in breast cancer demand a refinement of prognostic criteria. This study therefore investigated the prognostic relevance of cyclin expression in a cohort of 332 T1-T2 NO infiltrating ductal carcinomas with long-term follow-up (median 99 months). By univariate analysis, tumour size, histopathological grade, hormone receptor content, cyclin E, cyclin B, and the Ki-S5 (Ki-67) index
Objective. To assess the interaction between cystatin C (CysC) and serum amyloid A protein (SAA). Methods. Levels of CysC and SAA and antibodies against these proteins were assessed in the paired blood and synovial fluid (SF) samples of 90 patients with rheumatoid arthritis (RA). Age and sex matched individuals having normal iohexol clearance (n = 90) and SF following joint trauma (n = 40) were us
A group of investigators met at a Specialized Programs of Research Excellence Workshop to discuss key issues in the translation of biomarker discovery to the development of useful laboratory tests for cancer care. Development and approval of several new markers and technologies have provided informative examples that include more specific markers for prostate cancer, more sensitive tests for ovari
The hottest developments in the fields of cancer research, neuroscience, genomics and proteomics, anti-virals and more, with a pick of the key research papers in these areas.
Avian malaria parasites are supposed to exert negative effects on host fitness because these intracellular parasites affect host metabolism. Recent advances in molecular genotyping and microscopy have revealed that coinfections with multiple parasites are frequent in bird-malaria parasite systems. However, studies of the fitness consequences of such double infections are scarce and inconclusive. W
It has been proposed that hyaluronan-binding proteoglycans play an important role as guiding cues during neural crest (NC) cell migration, but their precise function has not been elucidated. In this study, we examine the distribution, structure and putative role of the two major hyaluronan-binding proteoglycans, PG-M/versicans and aggrecan, during the course of avian NC development. PG-M/versicans
OBJECTIVE: Overexpression of the human transcription factor FOXC2 gene ( FOXC2) protects against insulin resistance in mice and a common FOXC2 polymorphism (-512C > T) has been suggested to be associated with insulin resistance in humans. Here, we addressed the potential role for FOXC2 as a candidate gene for type 2 diabetes and associated phenotypes. MATERIALS AND METHODS: A case-control study wa
The presence of inhibitory antibodies to clotting factors complicates the treatment of bleeding in haemophilia patients. For patients with high-titre inhibitors, bypassing agents are essential to haemostatic management. To determine optimal treatment practices, an international panel of physicians convened to develop a systematic treatment approach for problem bleeds (i.e. bleeds that are unrespon
Prophylactic mastectomy is an effective risk-reducing option in women with hereditary increased risk of breast cancer. It may be combined with immediate reconstruction, with the intention of improving aesthetic outcome and health-related quality of life. Sixty-one women underwent prophylactic mastectomy and immediate breast reconstruction in Malmö, Sweden, between 1995 and 2003. Forty women under
Two novel vanadium complexes, [V(IV)O(bp-O)(HSO4)] (1) and [V(IV)O(bp-OH)Cl2] x CH3OH (2 x CH3OH), where bp-OH is 2-{[bis(pyrid-2-yl)methyl]amine}methylphenol, were prepared and structurally characterised. EPR spectra of methanol solutions of 2 suggest exchange of Cl- for CH3OH and partial conversion to [VO(bp-OH)(CH3OH)3]2+. Speciation studies on the VO2+-bpOH system in a water/dmso mixture (4:1
To examine possible species differences in pharmacology, rat adenosine A2A receptors were studied in PC12 (pheochromocytoma) cells, and human receptors in Chinese hamster ovary (CHO) cells transfected with the cloned human A2A receptor cDNA. Using [3H]-5-amino-7(2-phenylethyl)-2-(2-furyl)-pyrazolo[4,3-e]-1,2,4-triazolo [1,5-c]pyrimidine ([3H]-SCH 58261) as radioligand, the estimated Bmax (maximal
We conducted a multicentre, cross- sectional study of 1042 haemophilia subjects across Europe to compare various health outcomes associated with on-demand vs. prophylactic factor-substitution therapy. Demographic, medical history, and healthcare resource utilization data were analysed along with the number of bleeding events over the past 6 months. Treatment-cost data were also examined to provide
The aim of this article is to introduce an integrative and more comprehensive approach to understanding and measuring perceived housing in old age. First, four conceptual domains of subjective housing were introduced, based on the assumption that each of the domains brings a unique perspective to the understanding of perceived housing: housing satisfaction, usability in the home, meaning of home a
Popular Abstract in Swedish Populärvetenskaplig sammanfattning (Popularised summary in Swedish) Beta-microseminoprotein är ett äggviteämne (protein) som först hittades i sädesvätska (seminalplasma). Det är inte känt vad det har för funktion. Man känner i dag inte till någon som har brist på Beta-microseminoprotein eller någon sjukdom som beror på Beta-microseminoprotein. Den genetiska arvsmassan Human Beta-microseminoprotein is a 94 amino acid protein with 10 cysteins present in seminal plasma and on many mucosal surfaces in the body. The function of the protein is unknown. The purpose of this investigation was to study the distribution of Beta-microseminoprotein in the human body, especially in the stomach. The latter was studied under both normal and pathological conditions. A radioimmu
The reaction Ni-58(Ar-36, alpha-qp)88Mo has been studied at 145 MeV beam energy. A detector array consisting of the OSIRIS spectrometer, four charged-particle DELTA-E detectors and seven NE213 neutron detectors has been used to meaure the gamma radiation in gamma-gamma- and particle-gamma-gamma-coincidence mode. The level scheme of 88Mo has been extended up to 11.6 MeV excitation energy and probab
Objective. To investigate the inter- and intra-observer reliability of both qualitative and quantitative parameters used in the assessment of nail-fold capillaroscopy images.Methods. Fifty mosaic nail-fold images of healthy controls (n = 10), patients with primary RP (n = 10) and SSc (n = 30) were assessed in random order by two blinded observers on two occasions at centres in Sweden, UK and The N
