Vitamin C is known to protect mucosal tissues from oxidative stress and inhibit nitrosamine formation in the stomach. High consumption of fruits, particularly citrus, and higher circulating vitamin C concentrations may be inversely associated with gastric cancer (GC) risk. We investigated 20 polymorphisms in vitamin C transporter genes SCL23A1 and SCL23A2 and GC risk in 365 cases and 1,284 control

We report on recent new developments around the Astrometric Global Iterative Solution system. This includes the availability of an efficient Conjugate Gradient solver and the Generic Astrometric Calibration scheme that had been proposed a while ago. The number of primary stars to be included in the core solution is now believed to be significantly higher than the 100 Million that served as baselin

Acrylamide, classified in 1994 by IARC as 'probably carcinogenic' to humans, was discovered in 2002 in some heat-treated, carbohydrate-rich foods. The association between dietary acrylamide intake and epithelial ovarian cancer risk (EOC) has been previously studied in one case-control and three prospective cohort studies which obtained inconsistent results, and could not further examine histologic

The methanolic extract of Sesbania sesban Merrill (Fabaceae) raw seed materials contained total free phenolic content of 14.56 +/- 1.11 g catechin equivalent/100 g extract dry matter (DM). Encouraging levels of reducing power (FRAP, 1068 mmol Fe[II]/mg extract), inhibition of beta-carotene bleaching (49.80%) and scavenging activity against DPPH (51.65%) as well as superoxide (44.87%) radicals were

Increased production of autoantibodies is a characteristic feature of systemic lupus erythematosus (SLE) and there is evidence that several of these autoantibodies may contribute to the increased cardiovascular disease (CVD) in SLE. Autoantibodies against the apolipoprotein (apo) B-100 peptides p45 and p210 have been associated with a lower CVD risk in non-SLE cohorts. The aim of the present study

To evaluate the influence of hard exudates on macular function in patients with diabetic retinopathy. METHODS: Thirty seven eyes from 27 diabetic patients, aged 57 +/- 14 years, diabetes duration 12.5 +/- 9 years, not previously treated with photocoagulation, underwent fundus photography, multifocal electroretinography (mfERG) and optical coherence tomography (OCT). Hard exudates were graded from

Aerosol particles can modify cloud properties by acting as cloud condensation nuclei (CCN). Predicting CCN properties is still a challenge and not properly incorporated in current climate models. Atmospheric particle number size distributions, hygroscopic growth factors, and polydisperse CCN number concentrations were measured at the remote subarctic Stordalen mire, 200 km north of the Arctic Circ

To assess developmental outcomes of children aged 2.5 years born extremely preterm.

We here present simulations of the effect of border traps on the behavior of a III-V FET's transconductance with respect to frequency. We also compare simulations with a recently developed analytical model for extracting the border trap distribution through measurements of the transconductance, find good agreement between the extracted and simulated transconductance.

BACKGROUND: An increasing number of young patients are undergoing knee arthroplasties. Thus, the long-term risks of having a knee prosthesis must be evaluated. This study focuses on the potential carcinogenic effects of the prosthesis; it is a long-term follow-up of all patients in Sweden between 1975 and 2006. METHODS: The incidence of cancer in a total population of operated individuals was comp

The aim of the present study was to develop an understanding of how wheat plants can be used as a “green factory” by the modulation of genotype (G) and environmental (E) interactions to fine-tune the structure and increase the strength of gluten based materials. Two wheat genotypes (5 + 10 and 2 + 12) were grown under four nitrogen and two temperature regimes to obtain gluten of various characteri

To study family history in relation to curve severity, gender, age at diagnosis and treatment in idiopathic scoliosis. A self-assessment questionnaire on family history of scoliosis was administered to 1,463 untreated, brace or surgically treated idiopathic scoliosis patients. Out of the 1,463 patients, 51 % had one or more relatives with scoliosis. There was no significant difference between fema

Previous studies have reported an association between preterm birth and elevated blood pressure in adolescence and young adulthood. These studies were based on single-day blood pressure measurements and had limited ability to estimate risk of hypertension measured over a longer period and across the full range of gestational ages. The authors conducted a national cohort study of all infants born i

Proliferating excellence gold standards in the global academic system tend to obscure the far-reaching diversification of academic missions, practices, ambitions and identities brought by massification. This article approaches this topic by a review of theory on academic scholarship and how it has changed in the wake of academic massification and the development of binary higher education systems.

Hypoxia-inducible factors (HIFs) are differentially regulated in tumor cells. While the current paradigm supports post-translational regulation of the HIF-α subunits, we recently showed that hypoxic HIF-2α is also transcriptionally regulated via insulin-like growth factor (IGF)-II in the childhood tumor neuroblastoma. Here, we demonstrate that transcriptional regulation of HIF-2α seems to be restr

In Sweden, evidence-based national guidelines for the indication for reduction mammaplasty in the public health-care system have been developed by a group of experts. They were defined as breast volume ≥800 ml at normal weight. Furthermore, a volume asymmetry of 25% or at least 200 ml or an extreme ptosis may be an indication in some cases. The aim of the present paper was to describe an easy-to-u
