Definitive endoderm: a key step in coaxing human embryonic stem cells into transplantable beta-cells.
Using the Edmonton protocol, a number of patients with Type 1 diabetes mellitus have remained insulin-independent for prolonged periods of time. In spite of this success, transplantation of islets from cadaver donors will remain a therapy for very few patients owing to a lack of donors. Thus, if cell therapy should be widely available, it will require an unlimited source of cells to serve as a 'bi
Resource allocation in the new fixed and mobile Internet generation
In this paper we study the scalability issue in the design of a centralized policy server controlling resources in the future IP-based telecom network generation. The policy servers are in charge of controlling and managing QoS, security and mobility in a centralized way in future IP-based telecom networks. Our study demonstrates that the policy servers can be designed in such a manner that they s
A school curriculum-based exercise program increases bone mineral accrual and bone size in prepubertal girls: two-year data from the pediatric osteoporosis prevention (POP) study.
Sequential Elution from IMAC (SIMAC): An Efficient Method for Enrichment and Separation of Mono- and Multi-phosphorylated Peptides.
Phosphoproteomics relies on methods for efficient purification and sequencing of phosphopeptides from highly complex biological systems, especially when using low amounts of starting material. Current methods for phosphopeptide enrichment, e.g., Immobilized Metal ion Affinity Chromatography and titanium dioxide chromatography provide varying degrees of selectivity and specificity for phosphopeptid
Deontological Restrictions and the Good/Bad Asymmetry
A crack perpendicular to and terminating at a bimaterial interface
Using dislocation simulation approach, the basic equation for a finite crack perpendicular to and terminating at a bimaterial interface is formulated. A novel expansion method is proposed for solving the problem. The complete solution to the problem, including the explicit formulae for the T stresses ahead of the crack tip and the stress intensity factors are presented. The stress held characteris
Peripheral leucocyte count variations in rectal cancer treatment.
AIM: Mortality after curative surgery for rectal cancer is increased if surgery is not performed within a week of completed short course radiotherapy. A link to the suppression of leucocytes after neoadjuvant radiotherapy has been suggested. This study investigates the effects of radiotherapy on peripheral leucocyte counts, complications and survival. METHOD: Patient data variables from a retrospe
Social capital externalities and mortality in Sweden.
We conceptualize social capital as an aggregate factor affecting health production and analyze the effect of community social capital (CSC) externalities on individual mortality risk in Sweden. The study was based on a random sample from the adult Swedish population of approximately 95,000 individuals who were followed up for 4-21 years. Two municipality-level variables - registered election parti
Swedish CDKN2A mutation carriers do not present the atypical mole syndrome phenotype.
Phenotypic characteristics were examined in melanoma-prone southern Swedish CDKN2A (p16-113insArg/p14ARF-128insSer) mutation families, in relation to the CDKN2A genotype, nevi, clinically atypical nevi (CAN) and melanoma. Individuals from eight melanoma-prone families, with index patients carrying the CDKN2A mutation, were offered skin examinations and genotyping (CDKN2A and MC1R). Ninety-three in
Relationship between natriuretic peptides and echocardiography parameters in patients with poorly regulated type 2 diabetes.
This study evaluated the relationship between natriuretic peptide levels and a wide range of echocardiography parameters in a population of thirty-three patients with poorly regulated type 2 diabetes, and no known heart failure. Natriuretic peptides brain natriuretic peptide (BNP) and N-terminal prohormone BNP (NT-proBNP) were measured. Transthoracic echocardiography was performed and cardiac volu
Rheumatoid arthritis and the complement system
Complement activation contributes to a pathological process in a number of autoimmune and inflammatory diseases, including rheumatoid arthritis (RA). In this review we summarize current knowledge of complement contribution to RA, based on clinical observations in patients and in vivo animal models, as well as on experiments in vitro aiming at elucidation of underlying molecular mechanisms. There i
Shared familial aggregation of susceptibility to different manifestations of venous thromboembolism: a nationwide family study in Sweden.
Infiltration of Mast Cells in Rat Colon Is a Consequence of Ischemia/Reperfusion.
Intestinal ischemia as well as mastocytosis occur in patients with inflammatory bowel disease and irritable bowel syndrome. Our aim was to clarify how ischemia with reperfusion (I/R) affects the structure, enteric neurons, and immune cells in the colon. Rats were subjected to colon ischemia for 1 h and reperfused for 1 day up to 20 weeks; sham-operated rats were used as controls. No structural rem
Response to letter to by Dr Sert concerning the article "Robot assisted laparoscopic radical hysterectomy and pelvic lymphadenectomy with short and long term morbidity data"
A hybrid microdevice for electrophoresis and electrochromatography using UV detection
We have designed a new class of microdevices composed of a supporting plastic (polyvinyl chloride, PVC) plate integrated with a groove for a piece of fused silica capillary (the separation channel), a slit for on-tube detection, an “islet” for the application of sample, electrode vessels and platinum electrodes. The design permits electrophoretic, electrochromatographic and chromatographic separat
A fictitious energy approach for shape optimization
Comparison between two statistical downscaling methods for summer daily rainfall in Chongqing, China
Two circulation index-based methods were applied to downscale summer daily rainfall at four meteorological stations in Chongqing, China. One is a regression method (CIM) and the other a hybrid circulation classification plus regression method (CPM). Both methods used the same three circulation indices and surface specific humidity as predictors. In the first method (CIM), the indices and humidity
Systemic administration of anti-urokinase plasminogen activator receptor monoclonal antibodies induces hepatic fibrin deposition in tissue-type plasminogen activator deficient mice
BACKGROUND: Degradation of extracellular matrix proteins, such as fibrin, is pivotal to tumor invasion. Inhibition of the interaction between urokinase plasminogen activator (u-PA) and its receptor (u-PAR), and hence pro-u-PA activation, is an attractive approach to anti-invasive cancer therapy. A number of inhibitors exist for the human system, but because of species specificity none of these are
