Human papillomavirus genotypes in cervical cancers in Mozambique.

The distribution of human papillomavirus (HPV) types in cervical cancers is essential for design and evaluation of HPV type-specific vaccines. To follow up on a previous report that HPV types 35 and 58 were the dominant HPV types in cervical neoplasia in Mozambique, the HPV types in a consecutive case series of 74 invasive cervical cancers in Mozambique were determined. The most common worldwide m

Phylogeny and ecology of Cetraria obtusata, Coelopogon epiphorellus, and related taxa (Parmeliaceae, lichenized ascomycetes).

The phylogeny of two lichens, Cetraria obtusata from the Alps and Coelopogon epiphorellus occurring in the southern hemisphere is studied. A DNA-matrix based on ITS 1 and ITS 2 sequences of the rDNA is compared with a data set composed of morphology and secondary chemistry characters in phylogeny analyses using PAUP 4.0. The two data sets were entirely congruent. Neither Cetraria obtusata nor Coel

The changes in the rat parotid glands following total parenteral nutrition and pancreatico-biliary diversion are not mediated by cholecystokinin

CONCLUSIONS: The results of the present study suggest that the pancreas and parotid glands both respond with hypoplasia during absence of food in the digestive tract and with hyperplasia following pancreatico-biliary diversion (PBD). Factors other than cholecystokinin (CCK) are, however, involved in the effects on the parotid glands, since infusion of CCK-8S and devazepide was without influence. B

Glutamate detection from nerve cells using a planar electrodes array integrated in a microtiter plate

There is an increasing interest in new strategies for replacing animal tests in research. The use of cell cultures and integrated electrodes is seen as a promising alternative that could potentially solve this problem. In this work, we present a L-glutamate sensor based on a bienzyme redox hydrogel, capable of detecting the release of this excitatory neurotransmitter from adherently growing cells

Thermodynamics of a nonionic sponge phase.

Different suggestions for the mechanism governing the narrow stability of the L(3) (sponge) phase have led to a series of debates in recent years. There have been several models developed to describe such a mechanism via thermodynamics. To date, experimental data are insufficient to test present theories. In this study, we revisit the sponge phase with two series of thermodynamic data performed on

Relationships between locus of control, coping strategies and emotional well-being in persons with spinal cord lesion

Relations between locus of control, coping strategies and emotional well-being in persons with traumatically acquired spinal cord lesion (SCL) were examined. The sample included 132 community-residing adults. Structural equation modelling, including confirmatory factor analysis, was used. A model was hypothesized based on the transactional theory of stress and coping where coping strategies mediat

Effects of prey abundance and light intensity on nutrition of a mixotrophic flagellate and its competitive relationship with an obligate heterotroph

The mixotroph Poterioochromonas malhamensis was grown in batch and semicontinuous cultures in order to examine the dependence of phagotrophy versus phototrophy at bacterial densities similar to those found in oligo- and mesotrophic lakes in combination with differing light regimes. In addition, the growth rates and biomass accumulation of the mixotroph were compared to those of the heterotroph Spu

Automated detection of fundus photographic red lesions in diabetic retinopathy

PURPOSE. To compare a fundus image-analysis algorithm for automated detection of hemorrhages and microaneurysms with visual detection of retinopathy in patients with diabetes. METHODS. Four hundred fundus photographs (35-mm color transparencies) were obtained in 200 eyes of 100 patients with diabetes who were randomly selected from the Welsh Community Diabetic Retinopathy Study. A gold standard re

Stylistic Fronting

If stylistic fronting is analyzed as feature-driven movement into an articulated CP-domain, in particular FocusP in the sense of Rizzi (1997), it is possible to account for two facts about stylistic fronting that so far have received little attention, namely that stylistic fronting has semantic effects and that there are differences in stylistic fronting in subordinate clauses with no overt subjec

Comments on the scaling behavior of flexible polyelectrolytes within the Debye-Huckel approximation

Over the years, there has been much debate regarding the conformational behavior of flexible polyelectrolytes with electrostatic interactions described by the D bye-Huckel approximation. In particular, the electrostatic persistence length has been reported to depend both quadratically and linearly on the screening length as well as having no consistent power-law dependence at all. On the basis of

Den välfungerande arbetsgruppen. En genomgång av forskning och praktikererfarenheter

The purpose of this report is to present a critical review of research and practice based knowledge about factors conductive to ”good functioning” of work teams in the light of the evolving knowledge of developmental processes in groups. Conceptions of work team effectiveness are critically evaluated and new formulations presented. Factors such as two-way causality, boundary based defintions of te

The use of CRP tests in patients with respiratory tract infections in primary care in Sweden can be questioned

A diagnosis-antibiotic prescribing study was performed in 5 counties in Sweden during 1 week in November in 2000 and 2002 respectively. As a part of the study, the use and results of C-reactive protein (CRP) tests in relation to duration of symptoms and antibiotic prescribing in 6778 patients assigned a diagnosis of respiratory tract infections were analysed. In almost half (42%) of the patients,
