Neighborhood deprivation and risk of cervical cancer morbidity and mortality: A multilevel analysis from Sweden.

OBJECTIVES: To analyze whether there is an association between neighborhood deprivation and cervical cancer morbidity and mortality, beyond individual level characteristics. DESIGN: The entire Swedish population aged 25 to 74, a total of 1.9million women, were followed from January 1, 1990, until hospital admission due to cervical cancer during the study period, or the end of the study on Dece

The impact of maternal smoking during pregnancy on delivery outcome

BACKGROUND: Maternal smoking during pregnancy is associated with pre-term birth, intrauterine growth retardation, a small head circumference, a low Apgar score at 5 min and stillbirths and neonatal deaths. This study was undertaken in order to investigate the impact of maternal smoking during pregnancy when all these outcomes were considered. METHODS: With the use of the Swedish Medical Birth Regi

Retinal glial cell immunoreactivity and neuronal cell changes in rats with STZ-induced diabetes

PURPOSE: To study whether diabetes could influence glial cells, retinal neurons, and pigment epithelial cells and if so, to evaluate whether any changes could be influenced by aminoguanidine (AG) or probucol (PB). METHODS: Streptozocin (STZ)-induced diabetic male Wistar rats and age-matched control rats were fed a normal diet, addition of AG in the drinking water (0.5 g/l for diabetic and 1.0 g/l

Perivascular cell protection in vivo and increased cell survival in vitro by the antihypertensive agent carvedilol following radiation

Carvedilol, an antihypertensive drug with activity on adrenoceptors as well as on calcium channel activity, has recently been introduced. In the present study we investigated whether carvedilol interacts with the cytotoxicity induced by irradiation in vitro as well as in vivo. A daily injection of carvedilol in clinically relevant concentrations (3 mg/kg subcutaneously), 4 days before and 3 days a

Chronic Intestinal Pseudo-Obstruction due to Buserelin-Induced Formation of Anti-GnRH Antibodies.

Background & Aims: A 30-year-old woman, treated with buserelin, an analogue of gonadotropin-releasing hormone (GnRH) (also called luteinizing hormone-releasing hormone, LH-RH), developed chronic intestinal pseudo-obstruction (CIPO). The sudden onset of this disease in a previously healthy woman perplexed us. CIPO refers to a gastrointestinal disorder that can have a variety of causes, such as

Bacterial growth inhibited by a synthetic inhibitor based upon the structure of a human proteinase inhibitor

Cysteine proteinases are important not only in the intracellular catabolism of peptides and proteins1 and in the processing of prohormones and proenzymes2,3, but also in the penetration of normal human tissue by malignant cells4 and possibly microorganisms5, including viruses. Cystatin C is a human cysteine proteinase inhibitor present in extracellular fluids6. We have synthesized peptide derivati

Relative neurotoxin gene expression in clostridium botulinum type B, determined using quantitative reverse transcription-PCR.

A quantitative reverse transcription-PCR (qRT-PCR) method was developed to monitor the relative expression of the type B botulinum neurotoxin (BoNT/B) gene (cntB) in Clostridium botulinum. The levels of cntB mRNA in five type B strains were accurately monitored by using primers specific for cntB and for the reference gene encoding the 16S rRNA. The patterns and relative expression of cntB were dif

Transport equations for moist air at elevated wet bulb temperatures

In meteorological applications psychrometers are used both as a humidity transfer standard and as a measurement instrument. Unfortunately wet bulb temperature, t(wb), is not a thermodynamic property and consequently, in equation linking vapor pressure and temperature, the psychrometer constant, from now on called the psychrometer coefficient, a, must be experimentally evaluated. Both theoretical f

Theoretical study of structure of catalytic copper site in nitrite reductase

The catalytic copper site in nitrite reductase contains a Cu2+ ion bound to three histidine (His) ligands and a solvent molecule. Sites from various sources show a conspicuous variation in the structure. In some proteins, it is close to tetrahedral (even more so than are blue copper proteins), whereas in other proteins, it has a structure more similar to that expected for a type 2 copper site. We

The early ontogeny of neuronal nitric oxide synthase systems in the zebrafish.

To examine a putative role for neuronal nitric oxide synthase (nNOS) in early vertebrate development we investigated nNOS mRNA expression and cGMP production during development of the zebrafish Danio rerio. The nNOS mRNA expression in the central nervous system (CNS) and periphery showed a distinct spatio-temporal pattern in developing zebrafish embryo and young larvae. nNOS mRNA expression was fi

Time-resolved NIR/Vis spectroscopy for analysis of solids: Pharmaceutical tablets

Time-resolved spectroscopy in the visible and near-infrared (NIR) regions was used in a feasibility study for analysis of solid pharmaceuticals. The objective of the experiments was to study the interaction of light with pharmaceutical solids and to investigate the usefulness of the method as an analytical toot for spectroscopic analysis. In these experiments, a pulsed Ti:sapphire laser and white

Dual role of infections as risk factors for coronary heart disease.

Aims: The aim of the study was to explore whether exposure to microbial agents determines the prevalence of acute coronary events. Methods and results: Patients with unstable angina pectoris and myocardial infarction (N = 335) and their paired controls were investigated. The subjects answered a questionnaire about their childhood contagious diseases: varicella, scarlet fever, measles, rubella, mon

Effects of propofol on ipecacuanha-induced nausea and vomiting

BACKGROUND: The purpose of this study was to evaluate if propofol has 5-HT3 antagonistic effects. Ipecacuanha is known to release serotonin (5-HT) in the gastrointestinal tract and therefore ipecacuanha syrup was used to induce nausea and vomiting. The 5-HT3 antagonist ondansetron was used as a control substance. METHOD: Ten healthy male volunteers (20-37 years) were studied on three occasions and

Computational modelling of T-cell formation kinetics: output regulated by initial proliferation-linked deferral of developmental competence.

Bone-marrow-derived progenitors must continually enter the thymus of an adult mouse to sustain T-cell homeostasis, yet only a few input cells per day are sufficient to support a yield of 5 × 10(7) immature T-cells per day and an eventual output of 1-2 × 10(6) mature cells per day. While substantial progress has been made to delineate the developmental pathway of T-cell lineage commitment, still li

Extent and characteristics of self-reported pain in patients with systemic lupus erythematosus

Objective: Patients' own experiences of subjective symptoms are scarcely covered, and the objective of this study was to investigate the extent and characteristics of self-reported pain in patients with systemic lupus erythematosus (SLE). Methods: This study comprised a cross-sectional design where 84 patients with SLE were asked to complete self-assessments: visual analogue scale of pain and the

Maternal smoking during pregnancy and testicular cancer in the sons: A nested case-control study and a meta-analysis

Some large ecological studies have noted a significant association of testicular cancer (TC) with maternal smoking during pregnancy, while several more controlled studies have been negative. It has been difficult to obtain reliable data on exposure because of the long lag time to cancer diagnosis. We performed a case-control study nested within Finnish, Swedish and Icelandic maternity cohorts expl

Effects of polyols, saccharides, and glycoproteins on thermoprecipitation of phenylboronate-containing copolymers

The copolymer of 3-(acrylamido)phenyl boronic acid and N-isopropylacrylamide (82:18. M-n = 47000 g/mol) was prepared by free radical polymerization. The copolymer showed typical thermoprecipitation behavior in aqueous solutions; its phase transition temperature (T-p) was 26.5 +/- 0.2 degrees C in 0.1 M glycine-NaOH buffer containing 0.1 M NaCl, pH 9.2. Due to specific complex formation of the pend

Identification of cases of myocardial infarction: hospital discharge data and mortality data compared to myocardial infarction community registers

Identification of incident myocardial infarction (MI) cases in a defined population using hospital discharge data and mortality data in combination has been suggested. This method of case identification was compared to that of use of MI community registers set up in accordance with principles adopted in a World Health Organization collaborative programme. The comparison comprised data for four Swe
