BACKGROUND AND OBJECTIVES: Blood transfusion has been shown to be a risk factor for non-Hodgkin's lymphoma (NHL).MATERIALS AND METHODS: In a cohort of 77,928 women with bleeding complications at delivery in the period of 1973-1986, subsequent NHL cases were identified and the number was compared with the number expected from national incidence rates. In a case-control study the proportion of trans

OBJECTIVE: The aim of this study was to describe the clinical characteristics of early onset prostate cancer, with special reference to family history as a possible prognostic factor.MATERIAL AND METHODS: We identified all cases of prostate cancer diagnosed before the age of 51 in the Southern health care region in Sweden between 1958 and 1994. Clinical data were collected retrospectively from med

BRCA1 and BRCA2 mutations confer increased risk for development of breast cancer, but a number of additional, currently largely unknown, somatic genetic defects must also accumulate in the breast epithelial cells before malignancy develops. To evaluate the nature of these additional somatic genetic defects, we performed a genome-wide survey by comparative genomic hybridization on breast cancers fr

Risk factors of stroke/thromboembolism (TE) and major bleeding, and incidence of these events in specific age categories in warfarin-treated patients with mechanical heart valves (MHV) are uncertain. Our objective was to calculate event rates in specific age categories and identify risk factors for adverse events. Methods and results We identified 4,810 treatment periods with MHV between January 2

Background Breast-conserving surgery (BCS) followed by radiotherapy (RT) is an established treatment for women with T1-2N0 breast cancers. Since subgroups of patients have low ipsilateral breast tumour recurrence (IBTR) rates, it is important to study whether RT is necessary for all patients. Patients and methods A total of 1187 women with primary T1-2N0M0 breast cancer were randomised, after stan

Three founder mutations in BRCA1 and BRCA2 contribute to the risk of hereditary breast and ovarian cancer in Ashkenazi Jews (AJ). They are observed at increased frequency in the AJ compared to other BRCA mutations in Caucasian non-Jews (CNJ). Several authors have proposed that elevated allele frequencies in the surrounding genomic regions reflect adaptive or balancing selection. Such proposals pre

BACKGROUND: Colorectal carcinoma is one of the most common malignancies in the Western population, and a considerable proportion of colorectal carcinomas are estimated to have a familial background.METHODS: Individuals whose mothers were diagnosed with colon carcinoma or rectal carcinoma from 1958 to 1993, a total of 1. 48 million person-years, constituted the cohort of this Swedish population-bas

BACKGROUND: Women with mutations in either the BRCA1 or the BRCA2 gene have a high lifetime risk of ovarian cancer. Oral contraceptives protect against ovarian cancer in general, but it is not known whether they also protect against hereditary forms of ovarian cancer.METHODS: We enrolled 207 women with hereditary ovarian cancer and 161 of their sisters as controls in a case-control study. All the

Background: The consumption of sugar-sweetened beverages (SSBs), which has increased substantially during the last decades, has been associated with obesity and weight gain. Objective: Common genetic susceptibility to obesity has been shown to modify the association between SSB intake and obesity risk in 3 prospective cohorts from the United States. We aimed to replicate these findings in 2 large

The Swedish radiologist Torsten Almén is the first clinical radiologist ever to have made a fundamental contribution to intravascular contrast medium design, the development of non-ionic contrast media. He became emotionally triggered by the patients' severe pain each time he injected the ionic "high-osmolar" contrast media when performing peripheral arteriographies in the early 1960s. One day he

Detta är en pilotstudie som är utförd av Stefan Larsson, docent i teknik och social förändring vid Lunds universitets internetinstitut (LUii). Studien har utförts under 2016 på uppdrag av Konsumentverket i syfte att peka ut några av de för konsumentintresset viktigaste aspekterna med digitaliseringen. När man studerar digitalisering och dess konsumentbetydelse så ser man ganska snart att dess effe

Protein homeostasis in cells, proteostasis, is maintained through several integrated processes and pathways and its dysregulation may mediate pathology in many diseases including Duchenne muscular dystrophy (DMD). Oxidative stress, heat shock proteins, endoplasmic reticulum (ER) stress and its response, i.e. unfolded protein response (UPR), play key roles in proteostasis but their involvement in t

Today, commercially used brasses commonly contain 2 to 4 wt.% lead. As the availability of low-lead and lead-freebrass increase, there are environmental incentives for investigating the consequences of replacing thelead-containing brasses with lead-free equivalents. Generally, lead-free brass is expected to have a lowermachinability than its lead-alloyed counterpart, implying a higher manufacturin

Optogenetics is one of the most powerful tools in neuroscience, allowing for selective control of specific neuronal populations in the brain of experimental animals, including mammals. We report, for the first time, the application of optogenetic tools to human brain tissue providing a proof-of-concept for the use of optogenetics in neuromodulation of human cortical and hippocampal neurons as a po
