The interactions between herbivorous insects and their host plants have been central in generating diversification in both groups. We used a community of four yucca moth species, monophagous on the host plant Hesperoyucca whipplei (Agavaceae), to examine how the type of interaction and where insects feed within a plant influence phylogeographic structure of herbivorous insects. These four species
BACKGROUND: Calcitonin-related peptides have been found in the human prostate, and calcitonin (CT) and calcitonin gene-related peptide (CGRP) have been demonstrated in subpopulations of neuroendocrine (NE) cells. The purpose of this study was to determine the concentrations of CT and CGRP as well as the densities of NE cells in normal prostates, benign prostatic hyperplasia (BPH), and carcinoma of
Aim:The aim was to analyse any associations between socio-demographic and psychosocial factors and different features of the metabolic syndrome in a geographically well-defined population of middle-aged women. Methods:A population of 10 766 Caucasian women aged 50-59 years was investigated regarding biological and socio-demographic conditions, physical activity, dietary habits, aspects of quality
OBJECTIVES: The pattern of reflux in the most distal esophagus of asymptomatic individuals is largely unknown. Using a wireless technique we compared the degree and the pattern of acid reflux just above the squamocolumnar junction (SCJ) with that measured at the conventional level for pH monitoring. METHODS: Fifty-three asymptomatic volunteers underwent endoscopy with transoral placement of two pH
Blood coagulation factor IX is composed of discrete domains with an NH2-terminal vitamin K-dependent gamma-carboxyglutamic acid (Gla)-containing region, followed by two domains that are homologous with the epidermal growth factor (EGF) precursor and a COOH-terminal serine protease part. Calcium ions bind to the Gla-containing region and to the NH2-terminal EGF-like domain. To be able to determine
It is commonly assumed that speech production is initiated and guided by clear pre-verbal intentions. These intentions are moreover supposed to function as a standard of accuracy against which actual performance can be measured. Alternative positions to such a centrally governed process have been offered, but very few empirical attempts have been made to explore the issue. We aimed to remedy this
Popular Abstract in Swedish Östersjön är ett av världens största brackvattenhav och har stora miljömässiga problem orsakade av övergödning och varmare klimat. Det mer saltrika bottenvattnet som flödar in genom en smal förbindelse med Nordsjön skiljs från ytvattnet av en haloklin, vilket förhindrar ett utbyte av syre mellan de två vattenmassorna. Tillförsel av näring och ett varmare klimat leder tiThe Baltic Sea is one of the largest brackish water bodies in the world and is suffering extensive environmental issues caused by eutrophication and warming climate. A halocline in the water column divides more saline bottom water fed by inflows through the narrow connection with the North Sea from the surface waters and inhibiting exchange of oxygen between the two water masses. With the nutrient
The chapter makes use of the theoretic horizons of radical democrac, especially as found in the works of Chantal Mouufe, to conceptually explore the emergence of citizens' identities as active agents in the context of extra-parliamentarian political engagement using the Internet
beta 2-microglobulin (beta 2m) was found to interact with many group A streptococcal strains. The interaction appeared to require multipoint attachment, since monomeric beta 2m in solution showed no binding, whereas both beta 2m monomers bound to liposomes, and beta 2m in aggregates showed affinity for the bacteria. Aggregated HLA antigens (-A, -B and -C) and aggregated beta 2m exhibited the same
This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. By establishing air movement through an air-permeable layer below or above the concrete slab, the flowing air can absorb moisture from surroundi
Popular Abstract in Swedish Jordens havsnivå förändras kontinuerligt. I ett längre geologiskt tidsperspektiv styrs förändringarna av processer i jordens inre, men i ett kortare tidsperspektiv spelar yttre processer, såsom tillväxt och avsmältning av inlandsisar, stor roll för havets nivåförändringar. Det grönländska istäcket är idag norra halvklotets enda inlandsis och dess tillväxt och avsmältninNew results are presented from the investigation of relative sea-level changes in the Nanortalik and Qaqortoq-Narsarsuaq areas in SW Greenland from c. 11 000 cal. years BP to the present. Isolation and transgression sequences from seven lakes and seven tidal basins are identified using some of the traditional methods such as stratigraphic description, magnetic susceptibility, saturated induced rem
