The majority of aggressive forms of the childhood tumor neuroblastoma can with current treatment protocols not be cured and possess a major challenge in pediatric oncology. After initial rounds of chemotherapy, surgery and irradiation, which in most cases result in tumor regression, these aggressive neuroblastomas relapse and frequently develop drug resistance. As approximately 50% of the children
Sugarcane bagasse-a residue from sugar and ethanol production from sugar cane-is a potential raw material for lignocellulosic ethanol production. This material is high in xylan content. A prerequisite for bioethanol production from bagasse is therefore that xylose is efficiently fermented to ethanol, In the current study, ethanolic fermentation of steam-pretreated sugarcane bagasse was assessed in
Background: A reason for the digestive problems that often occur around early weaning in piglets could be that the pancreas is not yet fully developed and the enzymes required for degradation of the solid food are not secreted in enough amounts. Objectives: The aim of the study was to investigate the possibility of inducing pancreas maturation with enhanced enzyme secretion. Methods: 10-day-old su
We show that genomic-length DNA molecules imaged in nano-channels have an extension along the channel that scales linearly with the contour length of the polymer, in agreement with the scaling arguments developed by de Gennes for self-avoiding confined polymers. This fundamental relationship allows us to measure directly the contour length of single DNA molecules confined in the channels, and the
We contribute to the rapidly emerging interest in the application of time-of-flight secondary ion mass spectrometry (TOF-SIMS) for chemical analysis of biological materials by presenting a careful TOF-SIMS investigation of structurally different SiO2-supported phospholipid assemblies. Freeze-dried supported 1-oleoyl-2-palmitoyl-sn-glycero-3-phosphocholine (POPC) bilayers, Langmuir-Blodgett POPC mo
Although the negative effects of ultraviolet-B ( UV-B) radiation on the development of many amphibian species have been demonstrated, some speciessuch as the common frog ( Rana temporaria)seem to be tolerant of UV-B radiation. The amount of UV-B radiation received is likely to vary among populations of the same species, but little is known about geographic variation in UV-B tolerance. Similarly, a
Objective: To establish whether children with type 1 diabetes mellitus (T1D) with signs of pronounced beta-cell-specific autoimmunity as reflected by high autoantibody titers or positivity for several beta-cell-specific autoantibodies show a different pattern of month of birth (MOB) compared with children with T1D and low beta-cell autoimmunity and that of the general population. Research design a
The stratospheric ozone layer has been depleted at high and mid-latitudes as a consequence of man's pollution of the atmosphere, and this results in increasing ultraviolet-B radiation at ground level. We investigate the effects of further radiation increases on plants and ecosystems by irradiating natural sub-Arctic and Arctic vegetation with artificial W-B radiation in field experiments extending
The dic( 7; 9)( p11 similar to 13; p11 similar to 13) is a recurrent chromosomal abnormality in acute lymphoblastic leukemia (ALL), mainly of B-lineage. Although more than 20 dic(7; 9)-positive ALLs have been reported to date, the molecular genetic consequences of this aberration are unknown. We performed tiling resolution (32K) genome-wide array-based comparative genomic hybridization ( array CGH
Abstract in UndeterminedFluctuations of soil organism abundance, soil respiration and inorganic nitrogen werestudied in a laboratory experiment on material taken from the humus layer of a Scotspine forest and incubated under different moisture and temperature regimes. Theexperiment was run for 28 wk with samplings every 7 wk. At 28 wk, increases in"total movable N" (inorganic N + biomass N) were o
Background. We started a large multicenter prospective follow-up study to provide reliable risk estimates of venous thrombosis in families with various thrombophilic defects. Objectives: This paper describes data collected at study entry on venous events experienced before study inclusion, i.e. the baseline data. Patients/methods: All individuals (probands, relatives) registered in nine European t
Blood cysts within the heart are very rare entities in adults. The authors present possibly the first ever case in which blood cysts were found on both mitral valve leaflets. A 65-year-old woman was referred for transthoracic echocardiography because of vague chest discomfort. Transthoracic echocardiography displayed echo-free cysts on the tips of both mitral valve leaflets. Subsequent transesopha
Climate change and endeavours towards a sustainable society have brought the interest of wood-based biorefineries to the fore. Lignin is the main energy carrier in chemical pulp mills. Today, the heat value of lignin is commonly recovered in the recovery boiler of the mill. However, interest in the extraction of lignin for use as an external biofuel and in speciality chemicals is growing. Lignosul
Output normalized dose profiles for asymmetric open photon fields has been calculated using a commercial treatment planning system (TPS) based on a dose-to-energy-fluence concept. The model does not require any additional measurements for off-axis fields. Calculations are compared with measurements for quadratic fields of 5 cm x 5 cm up to 20 cm x 20 cm, with their geometric field centre positione
The finding that alkyl 1,4-dihydro-4-oxoquinoline-3-carboxylate and N-alkyl-1,4-dihydro-4-oxoquinoline-3-carboxamide derivatives may be high-affinity ligands at the benzodiazepine binding site of the GABAA receptor, prompted a study of 3-acyl-1,4-dihydro-4-oxoquinoline (3-acyl-4-quinolones). In general, the affinity of the 3-acyl derivatives was found to be comparable with the 3-carboxylate and th
Musculoskeletal conditions often manifest with the onset of pain and the resulting physical limitations. Musculoskeletal pain is almost inevitable in in individual's lifetime. It is one of the most common reasons for self-medication and entry into the health care system. Musculoskeletal pain affects in 4 adults and is the Most commons Source of serious long-term pain and physical disability. The M
Background The study examined client factors of relevance in the establishment of helping alliance and in the prediction of dropout from a routine psychiatric setting admitting a variety of diagnoses and staffed with a multiprofessional team. Method Newly admitted patients (n=122) and staff completed questionnaires regarding helping alliance, and the patients also completed questionnaires regardin
