Some dietary factors could be involved as cofactors in cervical carcinogenesis, but evidence is inconclusive. There are no data about the effect of fruits and vegetables intake (F&V) on cervical cancer from cohort studies. We examined the association between the intake of F&V and selected nutrients and the incidence of carcinoma in situ (CIS) and invasive squamous cervical cancer (ISC) in

Layered anorthosite complexes are typical components of Archean crustal domains. However, the geodynamic settings in which they were emplaced are still discussed as geological relationships are often ambiguous. Here we report major, trace element and high-precision high-field-strength-element (HFSE) data for the recently discovered well preserved Naajat Kuuat Anorthosite Complex from the inner Ame

A three-phase hollow fiber liquid phase microextraction (HF-LPME) method was evaluated for the extraction and preconcentration of naproxen and diclofenac using a polypropylene membrane followed by analysis using HPLC or LC/MS. In this technique, the drugs were extracted into di-n-hexyl ether immobilized in the wall pores of a porous hollow fiber from 50mL of sludge slurry sample as a donor phase w

For more than a decade now blue native polyacrylamide gel electrophoresis (BN-PAGE) has been used for the study of the oxidative phosphorylation (OXPHOS) complexes. Catalytic activities of complexes I, II, IV and V can be assessed, after separation by gel electroforesis, by incubation of the BN-PAGE gel in specific staining solutions. However, until now, a reliable staining method for testing ubiq

III-V Nanowires (NWs) grown with metal-organic chemical vapor deposition commonly show a polytypic crystal structure, allowing growth of structures not found in the bulk counterpart. In this paper we studied the radial overgrowth of pure wurtzite (WZ) GaAs nanowires and characterized the samples with high resolution X-ray diffraction (XRD) to reveal the crystal structure of the grown material. In

Two pregnane derivatives (1 and 2) were isolated from the methanolic root extract of Pentalinon andrieuxii, a plant used commonly in Yucatecan traditional medicine to treat leishmaniasis. The structures of both metabolites were established using spectroscopic methods and chemical correlation reactions. An X-ray structure of 1 is reported. (C) 2011 Phytochemical Society of Europe.

Introduction: Warfarin treatment with a high time in therapeutic range (TTR) is correlated to fewer complications. The TTR in Sweden is generally high but varies partly depending on local expertise and traditions. A dosing algorithm could minimize variations and increase treatment quality. Here we evaluate the performance of a computerized dosing algorithm. Materials and methods: 53.779 warfarin t

This paper compares two flow routing algorithms' influences on ecohydrological estimations in a northern peatland catchment, within the framework of an arctic-enabled version of the dynamic ecosystem model LPJ-GUESS. Accurate hydrological estimations are needed to fully capture vegetation dynamics and carbon fluxes in the subarctic peatland enviroment. A previously proposed distributed hydrologica

BRAF and NRAS mutations are frequently found in melanoma tumours and recently developed BRAF targeted therapies demonstrate significant clinical benefit.

BACKGROUND: Ciclosporin is used as an immunosuppressant in current clinical practice but recent research implies novel indications for the drug, such as neuro- and cardioprotection. The intravenous formulation currently on the market, Sandimmune(®) Injection (Sandimmune(®)), uses Cremophor(®) EL as emulsifying excipient. Cremophor(®) EL is known to cause hypersensitivity reactions in some patients

Active surveillance (AS) is an important yet underutilized strategy to reduce prostate cancer (PCa) overtreatment.

Background Limited information is available regarding genetic contributions to valvular calcification, which is an important precursor of clinical valve disease. Methods We determined genomewide associations with the presence of aortic-valve calcification (among 6942 participants) and mitral annular calcification (among 3795 participants), as detected by computed tomographic (CT) scanning; the stu

The future evolution of global ice sheets under anthropogenic greenhouse forcing and its impact on the climate system, including the regional climate of the ice sheets, are investigated with a comprehensive earth system model consisting of a coupled Atmosphere-Ocean General Circulation Model, a dynamic vegetation model and an ice sheet model. The simulated control climate is realistic enough to pe

Orthogonal P-wave morphology has previously been described in different populations, but its relation to atrial size has not been studied in detail. In this study, we investigated whether atrial size affects P-wave morphology in athletes, who are known to have different degrees of atrial enlargement.

Contrasting ecological conditions may affect the distribution, abundance and impact of parasites and predators throughout the ranges of hosts and prey. Such patterns are evident on the archipelagos of Hawaii and the Galapagos, which vary in their distribution and abundance of avian parasites within and across islands. Previous research has documented higher intensity of parasitic fly larvae (Philo

Recent design experiments have demonstrated that some proteins can switch their folds in response to a small number of point mutations either directly, in a single mutational step, or via intermediate bistable sequences, which populate two different folds simultaneously. Here we explore the hypothesis that bistable intermediates are more common in switches between structurally similar folds while

Background Therapeutic drug monitoring (TDM) of antibiotics in children is of fundamental importance for effective patient management. The use of dried blood spot (DBS) offers a number of advantages over conventional blood collection. The aim of this study is to develop and validate a method to measure piperacillin/tazobactam in DBS. Results The analysis was performed by using LC-MS/MS operating i

This paper deals with a continuous review inventory system with Poisson demand, in which lateral transshipments are allowed. In case of a shortage at a location, another location acts as a supplier, if it is possible. A common assumption in earlier papers is that transshipments are allowed between all locations. This network configuration may, however, not be the best choice for many reasons. one
