Cytogenetic analysis using Giemsa banding technique was successful in 30 of the 49 adult patients with nonHodgkin lymphomas investigated. The results are correlated with previous findings in 48 non‐Hodgkin lymphoma patients studied by means of fine needle aspiration in our laboratory. As 8 patients were included in both series, the total number successfully investigated was 70. The success rate wi
Chromosome studies of a solitary plasmocytoma in the femoral bone revealed a near-haploid chromosome number of 31-32 with a loss of one homolog of each chromosome pair except #1, #7, #9, #15, #19-21, and the sex chromosomes (XY). The cytogenetic findings have been compared with 16 cases of near-haploid neoplasms from the literature studied using banding techniques. A common feature present in 13 o

This thesis deals with ultrafast dynamics of electronic processes in rare gas atoms. The processes we explore include photoemission, where we time the emission of electrons moving away from the atomic core following ionization by a photon; and auto-ionization, where the atom spontaneously releases an electron wave-packet following photo-excitation. These processes occur on an attosecond and femtos
In 65 young women undergoing curettage for benign utrine disorders a signicicant relationship was found between early oral contraceptive use (starting age<25 years) and a high ratio of ln plasma prolactin versus ln estrogen receptor concentration of the uterine mucosae (p<0.047, Mann-Whitneys U-test). Year of birth, age at menarche, age at first full term pregnancy, parity, menstrual cycle phase a
To the Editor: The study on oral-contraceptive use and the risk of breast cancer from the Centers for Disease Control (CDC) and the National Institute of Child Health and Human Development (Aug. 14 issue)1 seems to be reassuring for oral-contraceptive users. But, as stated in the editorial by Shapiro in the same issue,2 there are some weak points that need further elucidation. We have found a high
Cytogenetic analysis was attempted in 20 patients with Hodgkin's disease. No mitoses were found in 2 cases, normal metaphases in 7, and normal metaphases with nonclonal aberrations in 7. Of the 4 cases with clonal aberrations, one had +16 as the sole change, whereas the remaining tumors had multiple numerical and structural changes.
In 18 untreated adult patients (median age 62.5 yr) with advanced non‐Hodgkin's lymphoma of unfavourable histology, thymidine labelling indices (LIs) of the lymphoma cells were assessed. The patients were treated with combination chemotherapy and have been followed for 29–60 (median 52) months or until death. The survival curve had a steep fall during the first 2 yr. Between 2–5 yr after treatment
The cytogenetic findings in 70 patients with non‐Hodgkin lymphoma have been correlated with tumor histopathology according to the Kiel classification. Certain chromosome aberrations displayed a nonrandom association with the grade of malignancy: 4 lymphomas out of 6 with 1p+, 5 out of 7 with del(6)(q15), 7 out of 11 with 14q+, and 5 out of 8 with +18 belonged to the high grade malignancy group, wh
At histopathological diagnosis of non-Hodgkin's lymphoma (NHL) the mean number of mitoses in 10 high power fields (×40) was determined in thin sections (2μm) and designated 'mitotic index' (MI). In 38 patients the thymidine labelling index (LI) of the lymphoma cells was also determined. There was a close correlation between MIs and LIs (r=0.81, P<0.001) indicating that MI reflects the proliferativ
The cytogenetic findings in samples from 106 patients with non-Hodgkin lymphomas (NHL), histopathologically classified according to the Kiel classification, have been correlated with survival time. Clonal chromosomal abnormalities were found in 60 patients, and only normal karyotypes in ten. The chromosome analysis of the remaining samples failed. The failures did not differ in survival compared w
The incidence of chromosome aberrations, i.e., chromatid and chromosome gaps, breaks, and exchanges, was studied in cultured skin fibroblasts from 25 untreated patients with non‐Hodgkin's lymphoma (NHL) and 26 controls. The mean frequencies of aberrant cells, and gap, break, and gap+break events per 100 metaphases were 4.2, 1.9, 2.8, and 4.7 in the NHL group, and 5.1, 2.6, 3.2, and 5.8 in the cont
The survival of 193 premenopausal breast cancer patients was investigated in relation to their history of early use of oral contraceptives. The women were born in 1939 or later and diagnosed in the southern health care region of Sweden. Women, who had started their oral contraceptive use (OC-use) before 20 years of age had a significantly lower survival rate as compared with those who had never us
X-ray phase-contrast imaging allows for non-invasive analysis in low-absorbing materials, such as soft tissue. Its application in medical or materials science has yet to be realized on a wider scale due to the requirements on the X-ray source, demanding high flux and small source size. Laser wakefield accelerators generate betatron X-rays fulfilling these criteria and can be suitable sources for p
