Taphofloras of the Koryak Upland and the Sagwon Locality of North Alaska are described in terms of their taxonomic composition, stratigraphic ranges, and comparison with coeval floras of Northeastern Russia and Alaska. Causes and amplitude of changes in Arctic floras across the Cretaceous-Paleogene boundary are considered. In its aspect and taxonomic composition, the Late Maastrichtian flora of th

OBJECTIVES: To examine pioglitazone as add-on to metformin and insulin secretagogues in patients with type 2 diabetes and inadequate glycaemic control and its effect on glycaemic control, surrogate measures of insulin sensitivity (adiponectin) and beta-cell function (proinsulin/insulin) and fluid retention.DESIGN AND SETTING: Prospective open-label study of 54 patients with type 2 diabetes and HbA

Previously [The abstract has been shortened somewhat, and the headings removed, in order to conform to journal style], we have observed vestibular asymmetry in about one-third of healthy senior citizens and in about two-thirds of subjects with previous hip fractures and no other significant ailments. Wrist fractures are considered a harbinger of hip fractures. If vestibular asymmetry is correlated

Due to our own preference for bright light, we tend to forget that many insects are active in very dim light. Nocturnal insects possess in general superposition compound eyes. This eye design is truly optimized for dim light as photons can be gathered through large apertures comprised of hundreds of lenses. In apposition eyes, on the other hand, the aperture consists of a single lens resulting in

Background and Purpose— Although stroke is strongly associated with hypertension, some individuals with normal blood pressure (BP) experience a stroke. This prospective study explored risk factors for stroke in subjects with normal BP. Methods— A total of 11 228 men and 17 174 women, 45 to 73 years old, were examined in a population-based cohort study. Normal BP was defined as BP

An autoregressive process with Markov regime is an autoregressive process for which the regression function at each time point is given by a nonobservable Markov chain. In this paper we consider the asymptotic properties of the maximum likelihood estimator in a possibly nonstationary process of this kind for which the hidden state space is compact but not necessarily finite. Consistency and asympt

This study was designed to investigate the motives patients give for attempting suicide and the associations between these motives and diagnosis, various psychiatric features, suicidal intent and socio-demographic characteristics. The Motives for Parasuicide Questionnaire (MPQ), comprising 14 suggested motives, was presented to 53 patients at a psychiatric ward that specialized in suicide attempte

Dendritic cells (DCs) play a crucial role in the sensitisation process. Upon encounter with an allergen, DCs require interactions with other cells and factors for triggering a primary or secondary immune response. Epithelial cells (ECs) express features of accessory cells, Such as expression of HLA-DR, co-stimulatory molecules, functional Fc gamma R, molecules of the antigen-processing machinery,

Biosensors for measurement of glycerol in FIA were constructed using NAD(+)-dependent glycerol dehydrogenase (GlDH) either co-immobilized with phenazine methosulphate (PMS) or cross-linked to an Os-complex-modified poly(vinylimidazole) redox polymer (PVI(13)dmeOs) using poly(ethyleneglycole) diglycidilether (PEGDGE). The GlDH/PMS sensor was characterized by a linear range of 0.01-1mM glycerol, a s

Question: Considering ecological factors and life history, how easy is it for sexual reproduction (as a strategy) to invade and persist in a population where all individuals are reproducing asexually? Mathematical method: We use a population growth equation that despite its simplicity captures several relevant ecological parameters: age-specific survival, differential birth rates, as well as both

Objective. To compare the efficacy and safety of intra-articular injections of two different hyaluronan preparations and placebo in patients with knee osteoarthritis. Methods. In a randomized, patient- and observer-blind, placebo-controlled and multicentre trial with parallel groups, 210 patients, aged 60 yr or above, with knee osteoarthritis were included in a per protocol analysis. The patients

Popular Abstract in Swedish Ämnet för denna tematiska och berättartekniska studie i litteraturvetenskap är C. J. L. Almqvists slottskrönika och det indirekta skrivsättet. Slottskrönikan omfattar romanerna Jaktslottet (1833), Hinden (1833) och Baron Julius K*. Ur Fröken Eleonoras Reseminnen (1835), vilka belyses med hjälp av Almqvists uppsats Om två slags Skrifsätt (1833). Denna infogades senare i The subject of this thematic and narrative-technical study is the Swedish author Carl Jonas Love Almqvist's (1793-1866) slottskrönika (castle chronicle) and the indirect way of writing. The castle chronicle comprises the novels Jaktslottet (The Hunting Castle; 1833), Hinden (The Hind; 1833) and Baron Julius K* (1835), all of which are included in Almqvist's great collective work, Törnrosens bok (T
