In a consecutive series of 150 women with breast cancer 122 had borne one or more children. Sixty-two patients were aged below 55 years at diagnosis (group A) and 60 were 55 years or older (group B). In group A 91 out of 153 children (59%) were boys compared with 48 out of 141 (34%) in group B (p=0 000007). In group A 54 of the 62 patients (87%) had given birth to one or more boys compared with 35
In this thesis, we draw inspiration from both classical system identification and modern machine learning in order to solve estimation problems for real-world, physical systems. The main approach to estimation and learning adopted is optimization based. Concepts such as regularization will be utilized for encoding of prior knowledge and basis-function expansions will be used to add nonlinear model
ABSTRACT. Using a standardized interview schedule, occupational exposure to organic solvents was investigated in 61 consecutive male patients with the diagnosis of non‐Hodgkin's lymphoma. When exposure was defined as handling of organic solvents every working day for at least one year, 23 patients were exposed and 38 non‐exposed. Of 15 patients with clinical stage I‐II above the diaphragm, 12 (80%
In vitro uptake of tritiated thymidine was studied in autoradiographic preparations of lymphoma cell suspensions obtained through fine-needle aspiration biopsy from 28 patients with non-Hodgkin's lymphoma. The labelling indices (LI ) were highest in patients with histiocytic or poorly differentiated lymphocytic lymphoma. During a two-year period there was a significant correlation between LI and s
A method for chromosome analysis of malignant cells by means of fine needle aspiration biopsy has been developed. The method has some obvious advantages compared to conventional surgical biopsy. During a 1-year period 25 consecutive non-Hodgkin, non-Burkitt lymphoma biopsies from 19 patients have been studied. In 14 out of 21 lymph node biopsies chromosome analysis was successful; whereas, four bi
By microcalorimetry the metabolic activity of malignant cells from 21 patients with non‐Hodgkin lymphoma was monitored. Heat production, a measure of the metabolic activity of cells, showed positive correlation with the clinical‐course of the disease. The heat produced by tumor cells from patients with progressive disease was 5.5 pW/cell, while that from patients responding to treatment was 3.1 pW
Five different human malignant melanoma were heterotransplanted subcutaneously to nude mice. When small tissue pieces were used 3 out of 5 tumors grew. Subcutaneous injections of suspended tumor cells were also made, but all failed to take. Metastatic or infiltrative growth was never seen in the mice observed for up to 2.5 months. The successful grafts largely retained the original morphological f
To the Editor: In a letter in the November 5 issue, Alperovitch and Feingold reported an increased sex ratio (male:female) among children of women with multiple sclerosis.1 We have observed a remarkably decreased sex ratio in the offspring of young adults with non-Hodgkin lymphoma. We recorded the sex of the children of 197 patients with this disease who were participating in an epidemiologic stud
A breast tumour from a 65-year old woman was found to be a primary non-Hodgkin lymphoma, a very rare primary malignancy in this location. The lymphoma was of a diffuse histiocytic type according to the classification of Rappaport, or polymorphic immunocytoma according to the Kiel classification. Immunohistochemistry, not previously reported for breast lymphomas, revealed the production of IgA. In
A compact combined sewer overflow (CSO) treatment unit is set up and evaluated in pilot-scale. The pilotplant consisted of flocculation, coagulation and a microsieving system followed by a disinfection unit with either O3 or ClO2. Efficiency of the pilot-plant was evaluated with respect to reduction of Escherichia coli, coliform bacteria and intestinal enterococci as well as removal of biocides. R
The pattern of heteromorphism in C‐band positive constitutive heterochromatin of human chromosomes Nos. 1, 9, and 16 was studied in peripheral lymphocytes from 78 patients with non‐Hodgkin lymphoma and 78 control individuals. The parameters of the heterochromatic regions analyzed were relative size, symmetry‐asymmetry within homologous pairs, and prevalence of inversions. No consistent differences
The pattern of heteromorphism in the C-band-positive constitutive heterochromatin of human chromosomes #1, #9, and #16 was studied in peripheral lymphocytes of 54 breast cancer patients and 78 control individuals. The parameters of the heterochromatic regions analyzed were relative size, symmetry-asymmetry within homologous pairs, and prevalence of inversions. Significant differences between the t
The photodissociation dynamics of CH3I and CH2ClI at 272 nm were investigated by time-resolved Coulomb explosion imaging, with an intense non-resonant 815 nm probe pulse. Fragment ion momenta over a wide m/z range were recorded simultaneously by coupling a velocity map imaging spectrometer with a pixel imaging mass spectrometry camera. For both molecules, delay-dependent pump-probe features were a
An occupational history of exposure to organic solvents, defined as daily occupational exposure for at least one year, was more common among 167 men with newly diagnosed non-Hodgkin's lymphoma than among 130 healthy referents from the general population (38 versus 14%). Categorization in five-year age groups gave 3.3 as a Mantel-Haenszel estimate of the odds ratio (95% CI 1.9-5.8). The odds ratio
To assist current efforts of the academic community to develop a fuller understanding of the function of general principles of international law, this article inquires into the operation of the principle of good faith. As argued, first, good faith serves as a principle of international legal pragmatics. It helps to explain the understanding of conduct in much the same way as, say, the requirement
