Immunostaining for p16(INK4a) used as a conjunctive tool improves interobserver agreement of the histologic diagnosis of cervical intraepithelial neoplasia

The quality of cervical histopathology is critical to cervical cancer prevention, cancer treatment, and research programs. On the basis of the histology results further patient management is determined. However, the diagnostic interpretation of histologic hematoxylin-eosin (H&E)-stained slides is affected by substantial rates of discordance among pathologists. Overexpression of the cyclin-depe

The phenotype in Norwegian patients with Bardet-Biedl syndrome with mutations in the BBS4 gene

Objective: To describe the phenotype of the Bardet-Biedl syndrome in patients with mutations in the BBS4 gene. Methods: We examined 3 pairs of siblings with Bardet-Biedl syndrome in whom 3 different mutations in the BBS4 gene were detected, 2 of which were homozygous for the mutation. Results: All patients had an increased body mass index. The obesity varied between families from moderate to sever

Effect of riparian structure, temperature and channel morphometry on detritus processing in channelized and natural woodland streams in southern Sweden

1. Ten south Swedish streams were selected to represent two distinct types - natural woodland streams and channelized streams. Measurements were made on leaching, decomposition and microbial respiration of the dominant riparian vegetation (European Black Alder), structure of the benthic macroinvertebrate community, macroinvertebrates inhabiting leaf material, channel morphometry, macrophyte compos

Boards of directors and entrepreneurial posture in medium-size companies: Putting the board demography approach to a test

A growing body of research suggests that a strong and vigilant board can have a significant influence on the value-creating potential of medium-size companies by favouring change and innovation in strategic decision-making. Yet how best to conceptualize this relationship remains controversial in scholarly circles. The mainstream approach has been to argue for a direct relationship between board de

Monte Carlo simulation of the photoneutron field in linac radiotherapy treatments with different collimation systems

Bremsstrahlung photon beams produced by linac accelerators are currently the most commonly used method of radiotherapy for tumour treatments. When the photon energy exceeds 10 MeV the patient receives an undesired dose due to photoneutron production in the accelerator head. In the last few decades, new sophisticated techniques such as multileaf collimators have been used for a better definition of

Dialysis-linked complaints and burdens of illness on patient and spouse as predictors of survival in end-stage renal disease patients with home hemodialysis: a 10-year follow-up study

Participants were 40 persons from a group of 44 end-stage renal disease patients in southern Sweden who in 1985 received home hemodialysis under the auspices of a hospital renal unit, together with their spouses (n = 35). At a 10-year follow-up, 15 of the patients had died and 25 had survived. Univariate log rank tests of the influence of physical and demographic factors, the patient's dialysis-li

Incommensurability and Vagueness

Two items are commensurable in value if and only if one of them is better than the other or if they are equally as good. They are incommensurable if none of these relations obtains. Given incommensurability, not even a purely ordinal measure is available for comparison: We cannot represent the relationship between the items by assigning a number to each that specifies the position of that item in

On computation of p-values in parametric linkage analysis

Parametric linkage analysis is usually used to find chromosomal regions linked to a disease (phenotype) that is described with a specific genetic model. This is done by investigating the relations between the disease and genetic markers, that is, well-characterized loci of known position with a clear Mendelian mode of inheritance. Assume we have found an interesting region on a chromosome that we

Pathways of anesthetic from the thoracic paravertebral region to the celiac ganglion

Communication between the lower thoracic paravertebral region and the celiac ganglion through the retrocrural space was investigated. After dye was injected into the endothoracic fascia in the lower thoracic paravertebral region at the T11 level, its spread to the celiac ganglion was examined in fifteen cadavers. The dye reached the celiac ganglion in nine cadavers (60%) by passing through the ret

Light-induced linear dichroism in photoreversibly photochromic sensor pigments 2. Chromophore rotation in immobilized phytochrome

Large phytochrome ((P) from Avena sativa) immobilized via anti-phytochrome immunoglobulin bound to Sepharose beads was irradiated to saturation with unpolarized far-red (fr) light. The apparent absorbance level was recorded in a dual wavelength spectrophotometer with both measuring beams set to either 600 or 730 nm and polarized perpendicular to each other. The sample was then irradiated with red

State-of-the-art: software inspections after 25 years

Software inspections, which were originally developed by Michael Fagan in 1976, are an important means to verify and achieve sufficient quality in many software projects today. Since Fagan's initial work, the importance of software inspections has been long recognized by software developers and many organizations. Various proposals have been made by researchers in the hope of improving Fagan's ins

Spontaneous cephalic version of breech presentation in the last trimester

A prospective longitudinal investigation of spontaneous cephalic version from breech presentation in the last trimester is reported. All pregnancies were assessed with ultrasound in the 32nd week of gestation, and were thereafter checked weekly. Of the 310 singleton breech presentations identified at 32 weeks, spontaneous cephalic version occurred in 177 (57%) while breech presentation persisted i

Model-independent interpretation of NMR relaxation data for unfolded proteins: the acid-denatured state of ACBP

We have investigated the acid-unfolded state of acyl-coenzyme A binding protein (ACBP) using N-15 laboratory frame nuclear magnetic resonance (NMR) relaxation experiments at three magnetic field strengths. The data have been analyzed using standard model-free fitting and models involving distribution of correlation times. In particular, a model-independent method of analysis that does not assume a

Effects of compost addition on extra-radical growth of arbuscular mycorrhizal fungi in Acacia tortilis ssp raddiana savanna in a pre-Saharan area

We studied the influence of added compost, consisting of Acacia cyanophylla leaves, on the production of extra-radical mycelia of arbuscular mycorrhizal (AM) fungi in natural stands of Acacia tortilis, which forms a desert savanna. Four different plots with different soil characteristics in terms of nutrient level and water-holding capacity were included in the study. The production of AM fungi wa

Autism and auditory brain stem responses

Objective: To study a controversy that has been discussed for more than two decades: whether or not children with autism have abnormalities affecting the cochlear nerve or the auditory pathway in the brain stem and, if so, to describe these abnormalities. Design: A group of 153 children and adolescents with autistic disorder were included in an investigation of auditory brain stem responses (ABR).

Relaxed dynamic programming in switching systems

In order to simplify computational methods based on dynamic programming, a relaxed procedure based on upper and lower bounds of the optimal cost was recently introduced. The convergence properties of this procedure are analysed here. In particular, it is shown that the computational effort in finding an approximately optimal control law by relaxed value iteration is related to the polynomial degre
