Comamonas testosteroni strain TI as a potential base for a microbial sensor detecting surfactants

Strain Comamonas testosteroni TI, capable of degrading the nonionic surfactant (NIS) nonylphenolethoxylate (OP-10), was used for constructing a pilot cellular biosensor. The lower NIS detection limit for the biosensor was 0.25 mg/l. We studied the substrate specificity of the biosensor with respect to a wide range of organic compounds: surfactants, polyaromatic compounds (PAC), carbohydrates, alco

Essays on Capital Structure

Chapter 2 analyses the relationship between capital structure and industry classification of Swedish firms. This study also analyses the determinants of the capital structure at the industry level. Since the assumption required for a parametric analysis of variances are not satisfied, a nonparametric method is applied to test for cross-industry differences in capital structure. The results show th

Loss of mismatch repair protein immunostaining in colorectal adenomas from patients with hereditary nonpolyposis colorectal cancer.

Colorectal adenomas occur at younger age, at increased frequency and have a greater tendency for malignant transformation in patients with hereditary nonpolyposis colorectal cancer (HNPCC). We performed immunostaining for the mismatch repair proteins MLH1, PMS2, MSH2 and MSH6 in 35 colorectal adenomas from 26 patients with HNPCC and identified loss of immunostaining in 23/35 (0.66) adenomas. Loss

Rädda en varg-Skjut en same: Den historielösa jämlikheten och föraktet för samer i Sverige

Save a Wolf – Shoot a Sami: Equality without History and the Hate Speech Against the Sami People in Sweden: During the last years there has been a considerable increase in hate speech against the Sami people in Sweden. This article explores the nature of this hate speech, why it has occurred and its structural basis. In order to overcome a relationship based on hate and disputes over the rights of

Monolayer of h-BN chemisorbed on Cu(111) and Ni(111): The role of the transition metal 3d states

The role of the transition metal 3d states in the adsorption of h-BN on Cu(111) and Ni(111) has been studied by NEXAFS and PE spectroscopies and by work function measurements. Based on the analysis of drastic differences in the spectra from h-BN/Cu(111) and h-BN/Ni(111), it has been concluded that the strength of chemical bonding at the interfaces under study is determined mainly by the strength o

Maastrichtian-Paleocene floras of Northeastern Russia and north Alaska and floral changes at the Cretaceous-Paleogene boundary

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

Glycemic and non-glycemic effects of pioglitazone in triple oral therapy in patients with type 2 diabetes mellitus

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

Observation of vestibular asymmetry in a majority of patients over 50 years with fall-related wrist fractures

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

Adaptations for nocturnal vision in insect apposition eyes

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

Risk Factors for Stroke in Subjects With Normal Blood Pressure. A Prospective Cohort Study.

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

Asymptotic properties of the maximum likelihood estimator in autoregressive models with Markov regime

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

Motives for suicide attempts. The views of the patients.

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

Interactions between dendritic cells and epithelial cells in allergic disease

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,
