Aim: Several studies have addressed the association between changes in the female sex hormones estrogen and progesterone levels and changes in parameters of periodontitis. In order to understand how these hormones affect periodontal health it is of major importance to obtain information on their physiological importance. We have previously shown that periodontal ligament cells (PDL cells) express

We encounter multimodality every day: in the newspapers, journals, ads, posters, story books, text books, leaflets, encyclopedias, instruction books, computer interfaces and in our interactions. Multimodality has been studied within many different disciplines: semiotics/sociosemiotics, textlinguistics, interface design, and human-computer-interaction. Yet, the approaches in the research of multimo

The purpose of this study was to investigate lifetime prevalence and characteristics of self-reported child sexual abuse and associations between child sexual abuse, gender, sociodemographic data, and consensual sexual experiences. A questionnaire was completed by 4,339 Swedish high school seniors. Three categories of child sexual abuse were studied: noncontact, contact without penetration, and pe

Erik Cinthio - an bibliography 1946-1985: Bibliography for professor in medieval archaeology Erik Cinthio; including contributions in newspapers and encyclopedias.

AIMS: The present study aims to quantify non-participation in the RIKS-HIA register during 2005 and to compare acute myocardial infarction (AMI) patients registered and not registered in RIKS-HIA, in relation to sociodemographic factors, prevalent disease, and 7-day and 30-day survival. METHODS: We linked information on sociodemographic characteristics, treatments, morbidity, and mortality from th

Decreased expression of Numb, resulting in activation of the proto-oncogene Notch1 and reduction in the tumor suppressor p53, has been demonstrated in mammary carcinomas. The aim of this study was to investigate the relationship between Numb protein expression and clinicopathological characteristics, tumor biological subtypes and putative cancer stem cell markers in a well-characterized cohort of

A Bidirectional Efficient Algorithm for Searching code Trees (BEAST) is proposed for efficient soft-output decoding of block codes and concatenated block codes. BEAST operates on trees corresponding to the minimal trellis of a block code and finds a list of the most probable codewords. The complexity of the BEAST search is significantly lower than the complexity of trellis-based algorithms, such a

Elevated concentrations of arsenic in drinking water are common worldwide, however, little is known about the presence of other potentially toxic elements. We analyzed 31 different elements in drinking water collected in San Antonio de los Cobres and five surrounding Andean villages in Argentina, and in urine of the inhabitants, using ICP-MS. Besides confirmation of elevated arsenic concentrations

The endoplasmic reticulum (ER) structure is of central importance for the regulation of cellular anabolism, stress response, and signal transduction. Generally continuous, the ER can temporarily undergo dramatic structural rearrangements resulting in a fragmented appearance. In this study we assess the dynamic nature of ER fission in pyramidal neurons in organotypic hippocampal slice cultures stim
