Early–Middle Ordovician biotic and sedimentary dynamics in the Baltoscandian paleobasin

Baltoskandien utgör en del av paleokontinenten Baltica, vilken mestadels var täckt av ett grunt epeiriskt hav under den ordoviciska tidsperioden (ca 485,5–444 Ma). Detta uråldriga hav efterlämnade en tunn lagerföljd av sedimentära bergarter. Under tidig–mellanordovicium (ca 485,5–457,5 Ma) befann sig Baltica vid tempererade breddgrader på södra halvklotet och kallvattenkarbonater bildades över stoThe Baltoscandian region forms part of the paleocontinent Baltica, which was largely covered by a shallow epeiric sea throughout much of the Ordovician (c. 485.5–444 Ma). This ancient sea is today recorded by a thin succession of sedimentary rocks. During the Early–Middle Ordovician (c. 485.5–457.5 Ma), Baltica was situated in mid-latitudes on the southern hemisphere and cool-water carbonates form

Somatic deletions in hereditary breast cancers implicate 13q21 as a putative novel breast cancer susceptibility locus

A significant proportion of familial breast cancers cannot be explained by mutations in the BRCA1 or BRCA2 genes. We applied a strategy to identify predisposition loci for breast cancer by using mathematical models to identify early somatic genetic deletions in tumor tissues followed by targeted linkage analysis. Comparative genomic hybridization was used to study 61 breast tumors from 37 breast c

Detecting migration routes and barriers by examining the distribution of species in an apomictic species complex

Aim The distribution of taxa ('microspecies') in the apomictic species complexes Hieracium L. sect. Hieracium and H. sect. Vulgata (Griseb.) Willk. and Lange have been analysed to test whether the geographical distribution of species within each complex will reflect historical processes and phenomena, e.g. historical barriers to migration and range expansion. It is argued that apomictic species ca

Trends in smoking behaviour between 1985 and 2000 in nine European countries by education

Objective: To examine whether trends in smoking behaviour in Western Europe between 1985 and 2000 differed by education group. Design: Data of smoking behaviour and education level were obtained from national cross sectional surveys conducted between 1985 and 2000 (a period characterised by intense tobacco control policies) and analysed for countries combined and each country separately. Annual tr

Polybrominated diphenyl ethers in aircraft cabins - A source of human exposure?

Commercial aircrafts need a high degree of fire protection for passenger safety. Brominated flame retardants (BFRs), including polybrominated diphenyl ethers (PBDEs), may be used for this purpose. Because PBDEs readily absorb to dust particles, aircraft crew and passengers may receive significant PBDEs exposure via inhalation. The aims of this work were to assess whether PBDEs could be found in ai

Defining Peer-to-peer Learning - from an Old Art of Practice to a New Mode of Forest Owner Extension?

This paper explores the concept of peer-to-peer learning (P2PL) in the context of North-European small-scale forest owners. The aim is to develop a framework for initiating new and evaluating already existing forest owners’ P2PL communities. Design: Previous studies of peer-learning are used to determine and justify eight dimensions for forest owners’ P2PL. To demonstrate and test the operability

Patient refusal of emergency cesarean delivery - A study of obstetricians' attitudes in Europe

OBJECTIVE: To compare the attitudes of a large sample of obstetricians from eight European countries toward a competent woman's refusal to consent to an emergency cesarean delivery for acute fetal distress. METHODS: Obstetricians' attitudes in response to a hypothetical clinical case were surveyed through an anonymous, self-administered questionnaire. The sample included 1,530 obstetricians (respo

MMP-26 mRNA and estrogen receptor alpha co-expression in normal and pathological endometrium

OBJECTIVE: To examine the expression pattern of matrix metalloproteinase-26 (MMP-26) mRNA and estrogen receptor-alpha (ER alpha) in normal, hyperplastic, premalignant and malignant endometrial tissue. DESIGN: Experimental study. SETTING: Department of Obstetrics and Gynecology of the Palacky University Medical School and University Hospital, Olomouc, Czech Republic, Department of Obstetrics and Gy

Consumption of dairy products in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort: data from 35955 24-hour dietary recalls in 10 European countries

Objectives: To describe and compare the consumption of dairy products in cohorts included in the European Prospective Investigation into-Cancer and Nutrition (EPIC). Methods: Data from single 24-hour dietary recall interviews collected through a highly standardised computer-based program (EPIC-SOFT) in 27 redefined centres in 10 European countries between 1995 and 2000. From a total random sample
