Case-control and cohort studies published between 1977 and 1988 were reviewed with the purpose to evaluate the relationship between use of oral contraceptives (OC-use) and breast cancer risk, tumour biology and tumour prognosis with special emphasis on early OC-use. the risk of breast cancer was assessed in 30 case-referent studies and 5 cohort studies, and the prognosis of breast cancer had been
Both animal and human data indicate that reproductive events taking place early in reproductive life may have an important influence on growth characteristics and reproductive hormone regulation in both normal tissue and neoplastic tissue investigated later in life.
One of many important features of blue-green infrastructure is the ability to lower flood risks by detention of stormwater. This ability of flood risk reduction has for the first time been evaluated with empirical data in this study. In 2014, Malmö, Sweden, was hit with extreme precipitation corresponding to a return period of 50–200 years that led to severe pluvial flooding. This and other large
Background: Leishmaniasis is a neglected and poorly reported parasitic infection transmitted by sand flies in tropical and subtropical regions. Knowledge about leishmaniasis has become important in non-endemic countries due to increased migration and travel. Few studies of the clinical management of cutaneous, mucocutaneous and visceral leishmaniasis in non-endemic regions have been published to d
BACKGROUND: The primary objective was to investigate the clinical and radiological outcome in patients undergoing major hip surgery using a novel antibiotic containing bone substitute for local augmentation in trochanteric fracture fixation or revision of total hip arthroplasty (THA).METHODS: We implanted a novel biphasic bone substitute CERAMENT™|G consisting of hydroxyapatite, calcium sulphate a
The ongoing trend towards synchrotron light storage rings with ultralow emittance lattices leads to greater challenges to achieve beam stability, sufficient Touschek lifetime, low heating of machine components, and conservation of the emittance at high bunch charge. One solution to meet these challenges is to lengthen the electron bunches with harmonic cavities. Many upgrade proposals therefore in
A conspicuous feature of the amyotrophic lateral sclerosis (ALS)-associated protein SOD1 is that its maturation into a functional enzyme relies on local folding of two disordered loops into a catalytic subdomain. To drive the disorder-to-order transition, the protein employs a single Zn2+ ion. The question is then if the entropic penalty of maintaining such disordered loops in the immature apoSOD1
Background: Diabetes is a risk factor for cognitive impairment, but whether there is also a link between pre-diabetes and cognitive dysfunction is not yet fully established. The aim of this observational study was to investigate associations between pre-diabetes/diabetes and cognitive test results, and also between glucose levels measured during the Oral Glucose Tolerance Test (OGTT) and cognitive
Background: Sex workers have high incidences of HIV and other sexually transmitted diseases. Although, interventions targeting sex workers have shown to be effective, evidence on which strategies are most cost-effective is limited. This study aims to systematically review evidence on the cost-effectiveness of sexual health interventions for sex workers on a global level. It also evaluates the qual
An adverse intrauterine environment is associated with long-term physiological changes in offspring. These are believed to be mediated by epigenomic marks, including DNA methylation (DNAm). Changes in DNAm are often interpreted as damage or plastic responses of the embryo. Here, we propose that stochastic DNAm variation, generated during remodeling of the epigenome after fertilization, contributes
Is there an interreligious potential in the way we approach death and eschatology? Christian eschatology often suggests a unity that puts an end to religious otherness. It is difficult to find explicit, appreciative statements of any kind of otherness in many eschatologies. Given this situation, how can a Christian eschatology articulate hospitality and room for the religious Other as other? And w
The heat of reaction of mercury diphenyl with hydrogen chloride in benzene solvent has been measured at 25°C. The heat of reaction of mercury diphenyl with mercuric chloride in methanol solvent has also been measured. From these heats of reaction, the heat of formation of mercury diphenyl has been derived: ΔHf° (Hgφ2, cryst.) = 65.4 ± 2 kcal/mole. Previous data on the heats of reaction of mercury
Chromosome analysis of lymphoma cells was performed in 54 untreated patients with non‐Hodgkin's lymphoma (NHL). 10 patients had a history of daily occupational handling of organic solvents for at least 1 year (exposed group) and 44 patients had never (or only for shorter periods) worked with solvents (unexposed group). There were no differences between exposed and unexposed patients regarding age,
Cholecystectomy has been connected with an increase in colorectal, breast and reproductive system cancers. On 472 patients, 398 women and 74 men, cholecystectomized during the years 1951 to 1955, cancer incidence was investigated. Our results show an elevated risk of breast cancer in the female group (P = 0.016), but no significant increased risk in colorectal or gynaecologic cancer. The risk for
The C‐band heterochromatin polymorphism of chromosomes 1, 9, and 16 was studied in lymphocytes from 52 lung cancer patients and 183 control persons. No significant differences between the controls and patients were found regarding heterochromatin block size, the frequency of partial and total inversions, or the symmetry/asymmetry pattern.
