Prevalence of delusional ideation in a district in southwestern Uganda.

Background: Population-based prevalence studies suggest that psychosis is a continuum distributed in the general population. Aim: To assess the prevalence of delusional ideation in young healthy individuals in a low-income country setting (Uganda) and to investigate possible relevant background factors. Method: Interviews were conducted in a district capital and in three rural villages, using the

Occupational engagement in persons with schizophrenia: relationships to self-related variables, psychopathology, and quality of life.

Previous research suggests that having schizophrenia involves not being fully equipped to engage in daily occupations. This study was aimed at exploring relationships between occupational engagement and the issues of self-related variables, psychiatric symptoms, and quality of life. Seventy-four outpatients with schizophrenia entered the study. Instruments used in this study were Profile of Occupa

Jones fracture. Surgical versus nonsurgical treatment

Sixty-three patients with 66 transverse and short oblique fractures of the proximal shaft of the fifth metatarsal bone (Jones fracture) were evaluated an average of five years (range, one to ten years) after the injury. There were 27 acute fractures and 39 chronic, or stress, fractures. The primary treatment was surgical for one third of the injuries and nonsurgical for the others. Surgical treatm

Humoral Immune Response Against Defined Oxidized Low-Density Lipoprotein Antigens Reflects Structure and Disease Activity of Carotid Plaques.

Background - Immune responses against oxidized low- density lipoprotein ( LDL) play an important role in atherosclerosis. The aim of this study was to investigate if humoral immune response against specific oxidized LDL antigens, such as aldehyde- modified peptide sequences of apolipoprotein B- 100, reflects disease activity and structure of atherosclerotic plaques. Methods and Results - Plaques w

Quasi-Lie algebras

This paper introduces a new class of algebras naturally containing, within a single framework, various deformations of the Witt, Virasoro and other Lie algebras based on twisted and deformed derivations, in addition to color Lie algebras and Lie superalgebras.

Protein D expression promotes the adherence and internalization of non-typeable Haemophilus influenzae into human monocytic cells

Protein D, having a glycerol-3-phosphodiester phosphodiesterase activity, is found at the surface of all Haemophilus influenzae strains and is a possible virulence factor. In the present study, the involvement of protein D in the entry of NTHi into human monocytic cells is reported. Primary monocytes and the monocytic cell lines U-937 and THP-1 were infected with NTHi strain 772 and the mutant 772

Autism spectrum disorder and underlying brain mechanism in the oculoauriculovertebral spectrum

As part of a multidisciplinary study, the rate of autism spectrum disorder (ASD), learning disability (LD), and brain abnormalities was examined in 20 participants (12 males, 8 females; age range 8mo-17y, mean age 8y 1mo) diagnosed as falling within the oculoauriculovertebral spectrum (OAV). A neuropsychiatric examination was performed, including standardized autism diagnostic interviews. Two indi

Radiation dosimetry in nuclear medicine

Radionuclides are used in nuclear medicine in a variety of diagnostic and therapeutic procedures. A knowledge of the radiation dose received by different organs in the body is essential to an evaluation of the risks and benefits of any procedure. In this paper, current methods for internal dosimetry are reviewed, as they are applied in nuclear medicine. Particularly, the Medical Internal Radiation

Fractional 13C enrichment of isolated carbons using [1-13C]- or [2-13C]-glucose facilitates the accurate measurement of dynamics at backbone Ca and side-chain methyl positions in protein

A simple labeling approach is presented based on protein expression in [1-C-13]- or [2-C-13]-glucose containing media that produces molecules enriched at methyl carbon positions or backbone C-alpha sites, respectively. All of the methyl groups, with the exception of Thr and Ile(delta 1) are produced with isolated C-13 spins (i.e., no C-13-C-13 one bond couplings), facilitating studies of dynamics

Comparison of mathematical formulas used for estimation of DNA synthesis time of bromodeoxyuridine-labelled cell populations with different proliferative characteristics

Growth kinetic data of human tumours, obtained by flow cytometric analysis of cells labelled with bromodeoxyuridine (BrdUrd) might provide prognostic information and allow prediction of response to radio- and chemotherapy. However, the theoretical models applied for calculation of growth kinetic data are not fully evaluated. The purpose of this study was to investigate the dependence of the estima

Catalytic Anisotropy of MoO3 in the Oxidative Ammonolysis of Toluene

The oxidative ammonolysis of toluene, i.e., ammoxidation without the presence of molecular oxygen, was studied over a series of samples of MoO3 crystals. The specific surface areas of the various faces were determined from SEM micrographs. Correlations between activities and surface planes were found. For the formation of nitrile the specific activity decreased in the order {001} and {h01} > {100}

Dynamics of intersexual conflict over precopulatory mate guarding in two populations of the isopod Idotea baltica

Aggressiveness during intersexual conflicts is predicted to depend on its costs, the value of winning and the power asymmetry of the contestants, all of which may vary between populations. In the marine isopod Idotea baltica (Pallas) a conflict occurs as females resist the attempts by males to start precopulatory mate guarding. We analysed contest dynamics with respect to female maturity stage, th

Resistance to NMDA toxicity correlates with appearance of nuclear inclusions, behavioural deficits and changes in calcium homeostasis in mice transgenic for exon 1 of the huntington gene

Transgenic Huntington's disease (HD) mice, expressing exon 1 of the human HD gene (lines R6/1 and R6/2), are totally resistant to striatal lesions caused by the NMDA receptor agonist quinolinic acid (QA). Here we show that this resistance develops gradually over time in both R6/1 and R6/2 mice, and that it occurred earlier in R6/2 (CAG-155) than in R6/1 (CAG-115) mice. The development of the resis

Is it possible to improve the patch-test diagnostics for isocyanates? A stability study of petrolatum preparations of diphenylmethane-4,4'-diisocyanate and polymeric diphenylmethane diisocyanate.

We have previously shown that the concentration of diphenylmethane-4,4'-diisocyanate (4,4'-MDI) in commercial test preparations was so low that patch testing with the same was not reliable. The stability of 4,4'-MDI in petrolatum (pet.) was compared with pet. preparations of polymeric diphenylmethane diisocyanate (PMDI), which consists of a complex mixture of monomeric isomers and oligomers of MDI

Cancer incidence in relatives of a population-based set of cases of early-onset breast cancer with a known BRCA1 and BRCA2 mutation status

Background Relatives of breast cancer cases have an increased risk of the disease. The risk increases with increasing numbers and decreasing age of onset of affected relatives. In families with a BRCA1 or a BRCA2 mutation, individual carrier status predicts the risk of breast cancer. In relatives of cases where both BRCA1 and BRCA2 mutations are excluded, the risk remains undetermined. Methods Sta

Quantum ratchets and quantum heat pumps

Quantum ratchets are Brownian motors in which the quantum dynamics of particles induces qualitatively new behavior. We review a series of experiments in which asymmetric semiconductor devices of sub-micron dimensions are used to study quantum ratchets for electrons. In rocked quantum-dot ratchets electron-wave interference is used to create a non-linear voltage response, leading to a ratchet effec
