Computerized image analysis as a tool to quantify infiltrating leukocytes : a comparison between high- and low-magnification images

The purpose of the present study was to establish a rapid and reproducible method for quantification of tissue-infiltrating leukocytes using computerized image analysis. To achieve this, the staining procedure, the image acquisition, and the image analysis method were optimized. Because of the adaptive features of the human eye, computerized image analysis is more sensitive to variations in staini

Vitamin D receptor polymorphisms and susceptibility to tuberculosis in West Africa: a case-control and family study

Vitamin D receptor (VDR) gene polymorphisms have been implicated in susceptibility to tuberculosis (TB), but reports have been inconsistent. We genotyped the VDR single-nucleotide polymorphisms (SNPs) FokI, BsmI, ApaI, and TaqI in 1139 case patients and control subjects and 382 families from The Gambia, Guinea, and Guinea-Bissau. The transmission-disequilibrium test on family data showed a signifi

Incidence and risk factors for depression and anxiety disorders: Results from a 34-year longitudinal Swedish cohort study.

This study is based on a total cohort (N = 192) of people born in 1902 and 1903 and living in southern Sweden. Subjects were assessed at baseline when 67 years of age and on eight further occasions over 34 years or until death. The participation rate in the nine examinations ranged from 78-100%. Interviews, psychological tests, and medical examinations were used as well as information on medical d

Effects of benthivorous fish on biogeochemical processes in lake sediments

1. Studies of aquatic environments have shown that community organisation may strongly affect ecosystem functioning. One common phenomenon is a change in nutrient level following a shift in the fish community composition. Although several hypotheses have been suggested, there is no consensus on which mechanisms are involved. Our study evaluated indirect effects of benthivorous fish on the biogeoch

The condensation energy of the homogeneous superconducting gas.

We present CHS, a computer program designed to calculate the condensation energy of the homogeneous superconducting electron gas. The correlation energy, which we treat at the level of the RPA, is an essential ingredient for the construction of a local density approximation in the framework of density functional theory for superconductors (SCDFT) [Kurth et al., Phys. Rev. Lett. 83 (1999) 2628].

Characterization of graphite electrodes modified with laccase from Trametes versicolor and their use for bioelectrochemical monitoring of phenolic compounds in flow injection analysis

Spectrographic graphite electrodes were modified through adsorption with laccase from Trametes versicolor. The laccase-modified graphite electrode was used as the working electrode in an amperometric flow-through cell for monitoring phenolic compounds in a single line flow injection system. The experimental conditions for bioelectrochemical determination of catechol were studied and optimized. The

Anti-lymphocyte function-associated antigen-1 monoclonal antibody inhibits CD40 ligand-independent immune responses and prevents chronic vasculopathy in CD40 ligand-deficient mice.

BACKGROUND: Blockade of CD40 ligand (CD40L; CD154, gp39) is a potential treatment for autoimmune disease and allograft rejection. However, CD40L-/- mice are capable of mobilizing cellular immune responses to viral, parasitic, and intracellular bacterial infections as well as rejecting skin grafts with nearly the same efficiency as wild-type mice. CD40L-deficient mice (CD40L-/-) or wild-type mice t

A fast algorithm for optimal alignment between similar ordered trees

We present a fast algorithm for optimal alignment between two similar ordered trees with node labels. Let S and T be two such trees with S and T nodes, respectively. If there exists an optimal alignment between S and T which uses at most d blank symbols and d is known in advance, it can be constructed in O(n log n (.) (maxdeg)(3) (.) d(2)) time, where n = max{S, T} and maxdeg is the maximum degree

Landslagsspråk och stadslagsspråk : stilhistoriska undersökningar i Kristoffers landslag

The thesis accounts for a comparison between the two different parts of The National Law of King Christopher (1442): the parts taken over from the older national law and the parts rewritten och new written. I also compare with those parts of The Urban Law of King Magnus Eriksson that are independent of the national law. The investigations concern legal case clauses, legal enactment modes, syntacti

Structural and functional damage sustained by mitochondria after traumatic brain injury in the rat: Evidence for differentially sensitive populations in the cortex and hippocampus

The cellular and molecular pathways initiated by traumatic brain injury (TBI) may compromise the function and structural integrity of mitochondria, thereby contributing to cerebral metabolic dysfunction and cell death. The extent to which TBI affects regional mitochondrial populations with respect to structure, function, and swelling was assessed 3 hours and 24 hours after lateral fluid-percussion

Receptor binding mimetics: a novel molecularly imprinted polymer

A novel molecularly imprinted polymer was prepared by copolymerization of trimethylolpropane trimethacrylate (1) and methacrylic acid (3) in the presence of a dipeptide acting as the template. The recognition capability of the synthetic receptor-like binding sites produced in the polymer network for the peptide was demonstrated by using the polymer as a chiral stationary phase in HPLC. The polymer

A misfit structure in the Co/Pt(111) system studied by scanning tunnelling microscopy and embedded atom method calculations

We have performed scanning tunnelling microscopy (STM) measurements of thin films of Co and CoPt alloys on Pt(111). In contrast to the interpretation of an earlier low energy electron diffraction investigation by Tsay and Shern [Surf. Sci. 396 (1998) 313] we find that the structure observed upon annealing a Pt(111) sample with a 2 ML (monolayer, ML) thick film of Co does not consist of a rotated C

Care and Discretion: Welfare States Revisited

This article analyses the consequences of using the concept of caregiving as a basis of extending social rights in the welfare state. By focusing on the administration of the right to a care allowance to a parent with a disabled child, the development of the concept of individualized justice and the use of discretion are examined. The article reveals how rights are differentially distributed throu

Correlative multielectron processes in K-shell photoionization of Ca, Ti and V in the energy range of 8-35 keV

The Kalpha satellite spectra arising from the correlative multielectron processes accompanying K-shell photoionization of Ca, Ti and V were measured using a broad range crystal spectrometer. Multiconfiguration Dirac-Fock calculations were performed to interpret the observed,x-ray energies and the spectral line shape., The calculations agree fairly well with the experimental results. The variation

Reproductive factors in hereditary breast cancer

BACKGROUND: An early age at menarche, a short menstrual cycle length, and a high age at first full term pregnancy or nulliparity are known risk factors for breast cancer. These risk factors have previously been reported to differ between breast cancer patients with and without a family history of breast cancer and also between breast cancer patients and controls. METHODS: Self-administered questio

Self-reported and measured time of vibration exposure at ultrasonic scaling in dental hygienists

In the present study, our objective was to quantify the daily duration of vibration exposure from ultrasonic scaling in dental hygienists and to compare different methods of self-estimates to time-recorded measurements. The exposure time was self-estimated by use of diary and interview methods in 10 subjects. We found that the measured total daily exposure time was limited, only on average 12 min,
