Since the late 1970s several epidemiological studies have appeared linking exposure to phenoxy herbicides or chlorophenols to some malignant tumors. Most of these compounds are contaminated with dioxins and dibenzofurans; for example, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a contaminant of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), a component of Agent Orange which was sprayed in Vietnam

The use of oral snuff is a widespread habit in Sweden. We investigated whether the use of Swedish moist snuff leads to an increasing risk of oral cancer. Other risk factors such as smoking tobacco and alcoholic beverages were also investigated. Our study comprised 410 patients with oral cancer, from the period 1980-1989, and 410 matched controls. All subjects received a mailed questionnaire. The r

We investigated the role of oral infections, dentition and dental X- rays for oral cancer in a north Swedish population. This case-control study consisted of 410 cases with oral cancer for the period 1980-89 and 410 matched controls. All subjects received a mailed questionnaire. The response rates were 96% and 91% for cases and controls, respectively. The univariate analysis showed a statistically

Some earlier reports have indicated increased incidence or mortality of specific tumor types in various health care professions. In this study we have evaluated cancer incidence in physicians, dentists, and other health care workers using the Swedish Cancer Environment Register (CER), which was formed by record-linkage between the 1970 census on current occupation and Cancer Register incidence dat

In a case-control study with 410 cases and 410 matched controls from the period 1980-1989 we investigated the role of occupations and occupational exposures as risk factors for squamous cell oral cancer. All subjects received a questionnaire. The response rates were 96% and 91% for cases and controls, respectively. A significantly increased risk was found for pulp industry workers, odds ratio (OR)

BACKGROUND. The incidence of non-Hodgkin lymphoma (NHL) has increased in most Western countries during the last few decades. Immunodefective conditions are established risk factors. In 1981, the authors reported an increased risk for NHL following exposure to certain pesticides. The current study was designed to further elucidate the importance of phenoxyacetic acids and other pesticides in the et

Genomic rearrangements in cancer can join the sequences of two separate genes. Studies of such gene fusion events have mainly focused on identification of fusion proteins from the chimeric transcripts. We have previously investigated how fusions instead can affect the expression of intronic microRNA (miRNA) genes that are encoded within fusion gene partners. Here, we extend our analysis to small n

More than 40% of Dutch women are not financially independent. Tax incentives for single earning families encourage this dependence. In this essay in the Dutch financial newspaper Sigrid Hemels argues that it does not make sense to keep such incentives in times as ours in which 40% of all marriages ends in divorce and in which we are faced with increased cost and a reduced workforce due to the agei

We summarise here the information to be provided to women and referring physicians about percutaneous breast biopsy and lesion localisation under imaging guidance. After explaining why a preoperative diagnosis with a percutaneous biopsy is preferred to surgical biopsy, we illustrate the criteria used by radiologists for choosing the most appropriate combination of device type for sampling and imag

Sm2+ and Sm3+ co-doped SrB4O7 could be utilized in several high-level optical devices and fundamental knowledge about the optical behavior of these materials benefits the development of luminescent applications. Herein, we report luminescence and its vacuum ultraviolet (VUV) excitation spectra in samarium doped SrB4O7. Both, Sm2+ and Sm3+ luminescence centers have been examined and distinguished i

Background: Increased inflammation is reported in Major Depressive Disorder (MDD), which may be more pronounced in suicidal subjects. Vitamin D deficiency may drive this pro-inflammatory state due to vitamin D's anti-inflammatory effects. Methods: We quantified plasma 25-hydroxyvitamin D (25(OH)D) and inflammatory markers interleukin (IL)-6 and tumor necrosis factor (TNF)-α, and other inflammatory

My paper studies the nominal system in a dialect of Småland, spoken in Urshult,as it has been coded and transcribed in a volume by Swea Johansson, a native speaker of this dialect. In this variety, a large portion of the weak feminines, in modern Swedish roughly nouns ending -a, for example penna ’pencil’, instead end in -e, penne ’pencil’. Furthermore, the definite form frequently ends in -na, pe: My paper studies the nominal system in a dialect of Småland, spoken in Urshult,as it has been coded and transcribed in a volume by Swea Johansson, a native speaker of this dialect.

We investigated the skin sensitization hazard of glyphosate, the surfactant polyethylated tallow amine (POEA) and two commercial glyphosate-containing formulations using different omics-technologies based on a human dendritic cell (DC)-like cell line. First, the GARD™skin assay, investigating changes in the expression of 200 transcripts upon cell exposure to xenobiotics, was used for skin sensitiz

Cognitive reserve (CR) is thought to protect against the consequence of age- or disease-related structural brain changes across multiple cognitive domains. The neural basis of CR may therefore comprise a functional network that is actively involved in many different cognitive processes. To investigate the existence of such a “task-invariant” CR network, we measured functional connectivity in a cog

The transformation of an atomic nucleus into two excited fission fragments is modeled as a strongly damped evolution of the nuclear shape. As in previous studies, it is assumed that the division of mass and charge is frozen in at a critical neck radius of c0=2.5fm. In order to also determine the energetics, we follow the system further until scission occurs at a smaller neck radius, at which point

Health education materials such as flipbooks enhance learning and deliver key messages in a captivating mode. Validation of such materials is crucial to ensuring implementation fidelity. We conducted a study to achieve two objectives: (a) to develop two flipbooks, one each for adolescents and young married women (YMW); (b) to validate the flipbooks using five parameters, namely, content validity,

There is an established link between birth parameters and risk of adult-onset cancers. The Developmental Origins of Health and Disease concept provides potential underlying mechanisms for such associations, including intrauterine exposure to endogenous hormones (androgens and estrogens), insulin-like growth factors, etc. However, there is conflicting evidence on the association between birth param

Background and purpose: Patients’ adherence to medication is a complex, multidimensional phenomenon. Dispensation data and electronic health records are used to approximate medication-taking through refill adherence. In-depth discussions on the adverse effects of data quality and computational differences are rare. The purpose of this article is to evaluate the impact of common pitfalls when compu
