Separation of fungal propagules by partition in aqueous polymer 2-phase systems

Conidia of Penicillium chrysogenum and Penicillium frequentans and sporangiospores of Rhizopus rhizopodiformis, Rhizomucor pusillus, and Mucor racemosus were subjected to partition in aqueous polymer two-phase systems. The partition behavior differed drastically between the conidia of the two Penicillium species and the sporangiospores of the three species of phycomycetes. This difference in parti

A synthesis method for robust PID controllers for a class of uncertain systems

PID controller design is considered where optimal controllerparametersare found with constraint on maximum sensitivity and robustness withregard to a cone bounded static nonlinearity acting in feedback withpart of the plant. Thedesign procedure has been successfully applied in the synthesis of acontroller for an Anti-lock Braking System (ABS).

Spin Hall effect on edge magnetization and electric conductance of a 2D semiconductor strip

The intrinsic spin Hall effect on spin accumulation and electric conductance in a diffusive regime of a 2D electron gas has been studied for a 2D strip of a finite width. It is shown that the spin polarization near the flanks of the strip, as well as the electric current in the longitudinal direction, exhibit damped oscillations as a function of the width and strength of the Dresselhaus spin-orbit

Quantification of myocardial perfusion defects using three different software packages.

Software packages are widely used for quantification of myocardial perfusion defects. The quantification is used to assist the physician in his/her interpretation of the study. The purpose of this study was to compare the quantification of reversible perfusion defects by three different commercially available software packages. We included 50 consecutive patients who underwent myocardial perfusion

Familial association between type 1 diabetes and other autoimmune and related diseases

In the era of genome-wide association studies, familial risks are used to estimate disease heritability and success in gene identification. We wanted to estimate associations between type 1 diabetes mellitus and 33 autoimmune and related diseases in parents, offspring, singleton siblings and twins. The availability of a Multigeneration Register in Sweden provides reliable access to families throug

Quantitative measurements of species and temperature in a DME-air counterflow diffusion flame using laser diagnostic methods

A diffusion flame of dimethyl ether (DME) and air in a counterflow burner has been investigated experimentally by means of different laser-based methods. Quantitative measurements of temperature, O-2 concentration, and OH concentration have been carried out using dual broadband rotational coherent anti-Stokes Raman Spectroscopy (CARS), Rayleigh scattering and laser-induced fluorescence (LIF). Furt

Gender influences beliefs about health and illness in diabetic subjects with severe foot lesions.

Background. No studies have been found regarding beliefs about health and illness in patients with diabetic foot ulcers investigated from a patient perspective. Beliefs might affect self-care and health. Aim. To explore beliefs about health and illness among patients with severe diabetic foot lesions that might affect self-care practice and care-seeking behaviour. Method. The study design was ex

Characterization of a novel breast carcinoma xenograft and cell line derived from a BRCA1 germ-line mutation carrier

A human tumor xenograft (L56Br-X1) was established from a breast cancer axillary lymph node metastasis of a 53-year-old woman with a BRCA1 germ-line nonsense mutation (1806C>T; Q563X), and a cell line (L56Br-C1) was subsequently derived from the xenograft. The xenograft carries only the mutant BRCA1 allele and expresses mutant BRCA1 mRNA but no BRCA1 protein as determined by immunoprecipitation or

Candelariella (Candelariaceae) in western United States and northern Mexico: the species with biatorine apothecia

Three species of Candelariella in western North America, characterized by biatorine apothecia, are treated. Two new species are described, C. biatorina and C. lichenicola. Candelariella biatorina is a corticolous species growing in montane conifer forests in western North America. Candelariella lichenicola, described from northwestern Mexico, is a lichenicolous fungus that lacks an independent tha

Eye structure correlates with distinct foraging-bout timing in primitive ants

Social insects have evolved remarkable physiological adaptations and behavioural strategies that enable them to access new temporal foraging niches (for example [1]). Here we report striking correlations between the timing of foraging bouts and the modification of eye structure in four species of ants belonging to the primitive genus Myrmecia. Most noteworthy, photoreceptor diameters progressively

Effects of drugs and electrical field stimulation on isolated muscle strips from rabbit pharyngoesophageal segment

Muscle activity of isolated muscle strips from the middle pharyngeal constrictor, the inferior pharyngeal constrictor, the cricopharyngeal muscle, and the cervical esophagus of the rabbit was studied in organ baths in response to drugs and electrical field stimulation. These muscles of the pharyngoesophageal segment seem to lack an autonomic adrenergic and cholinergic innervation, as determined by

Efficient simulation of adaptive optics technologies for the Euro50 telescope

An efficient adaptive optics (AO) simulation code was developed, which enables first-order simulations of extremely high-order systems. The Monte-Carlo-type code employs a sparse conjugate gradient algorithm for wavefront reconstruction, and a separation of spatial frequencies into two domains to economize on the number crunching. High-order multi-conjugate adaptive optics (MCAO) systems are there

Swallowing and respiratory pattern in young healthy individuals recorded with high temporal resolution

P>The coordination of swallowing and respiration is essential for a safe swallow. Swallowing consists of several subsecond events. To study this, it is important to use modalities with high temporal resolution. In this study, we have examined young healthy individuals with simultaneous videofluoroscopy, videomanometry and respiratory recording, all with high temporal resolution. The onset of 13 pr

The expression of retinoic Acid receptors and the effects in vitro by retinoids in human pancreatic cancer cell lines.

INTRODUCTION: Analogues of vitamin A have been shown to influence growth of malignant tissue, such as pancreatic cancer. AIMS: To study the expression of retinoic acid receptors (RAR) in pancreatic cancer cells and the effect of three different retinoids on the cell number in vitro were studied. METHODOLOGY: Cell lines were established from 13 patients who underwent surgery for pancreatic adenocar

Boosting Antimicrobial Peptides by Hydrophobic Oligopeptide End Tags

A novel approach for boosting antimicrobial peptides through end tagging with hydrophobic oligopeptide stretches is demonstrated. Focusing on two peptides derived from kininogen, GKHKNKGKKNGKHNGWK (GKH17) and HKHGHGHGKHKNKGKKN (HKH17), tagging resulted in enhanced killing of Gram-positive Staphylococcus aureus, Gram-negative Escherichia coli, and fungal Candida albicans. Microbicidal potency incre

Myosin heavy chain isoforms influence surface EMG parameters: a study of the trapezius muscle in cleaners with and without myalgia and in healthy teachers.

The present study had two aims: (1) to investigate potential differences in proportion of myosin heavy chain isoforms in the trapezius muscle between female cleaners with and without trapezius myalgia and healthy teachers, and (2) to elucidate if myosin heavy chain composition and surface electromyogram (EMG) during an isokinetic endurance test of shoulder flexors are significantly related. The su

Astrophysical lasers in optical Fe II lines in gas condensations near η Carinae

We report here on the discovery of laser action in the range 0.9-2 μm in several spectral lines of Fe II, which are associated with transitions from "pseudo-metastable" states populated by spontaneous transitions from Lyα pumped Fe II levels. The intense Lyα radiation is formed in the HII region of gas condensations close to the star η Car. The laser transitions form together with spontaneous tran
