Inhibition of diamine oxidase promotes uptake of putrescine from rat small intestine

In blood from the portal vein of anaesthetized rats the levels of histamine and putrescine were 2-3-fold lower compared to arterial blood. Putrescine concentration was increased severalfold and the difference between portal and arterial blood abolished in animals pretreated with the specific diamine oxidase inhibitor aminoguanidine. Histamine concentration was 40% lower in portal compared to arter

Epinephrine for transient tachypnea of the newborn

Background: Transient tachypnea of the newborn is characterized by tachypnea and signs of respiratory distress. Transient tachypnea typically appears within the first two hours of life in term and late preterm newborns. Although transient tachypnea of the newborn is usually a self limited condition, it is associated with wheezing syndromes in late childhood. The rationale for the use of epinephrin

Effects of receptor agonists on polyamine concentrations and spermidine/spermine N1-acetyltransferase activity in rat parotid gland

The polyamine putrescine might be formed via a degradation (catalyzed by spermidine/spermine N1-acetyltransferase, SSAT) of the higher polyamines spermidine and spermine to putrescine. The involvement of different intracellular signal pathways in the regulation of putrescine formation was studied in explants and in cultured cells of rat parotid glands by using receptor agonists that activate separ

Polyamines and long-term disuse of rat parotid glands

A decrease in nerve reflex activation for 7-14 days, induced by a liquid diet, caused the rat parotid gland to lose weight, involving reduction in both cell size and number. In the atrophied glands, the activity of ornithine decarboxylase, the key enzyme in polyamine formation, and the levels of the polyamines putrescine, spermidine and spermine were found to be lowered. The present results are co

Interaction between rs10830963 polymorphism in MTNR1B and lifestyle intervention on occurrence of gestational diabetes

Aims/hypothesis: The aim of this study was to assess the interaction between melatonin receptor 1B gene (MTNR1B) rs10830963 polymorphism and lifestyle intervention during pregnancy on occurrence of gestational diabetes mellitus (GDM) in high-risk women. Methods: This is a secondary analysis of the randomised controlled gestational diabetes prevention trial ‘RADIEL’, conducted between 2008 and 2014

Substance P and vasoactive intestinal peptide influence polyamine metabolism in salivary glands of the rat

In parotid, sublingual and submaxillary glands stimulated by continuous intravenous infusion of the neuropeptides substance P or vasoactive intestinal peptide at various doses for 3 h, the concentrations of the polyamines putrescine, spermidine, spermine and N1-acetylspermidine as well as the activity of ornithine decarboxylase were determined. This enzyme catalyses the synthesis of putrescine and

Meal patterns across ten European countries – results from the European Prospective Investigation into Cancer and Nutrition (EPIC) calibration study

Objective: To characterize meal patterns across ten European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) calibration study. Design: Cross-sectional study utilizing dietary data collected through a standardized 24 h diet recall during 1995–2000. Eleven predefined intake occasions across a 24 h period were assessed during the interview. In the p

Typological and developmental considerations on Specific Language Impairment in monolingual and bilingual children : a Processability Theory account

This article suggests a method to deal with cross-linguistic differences in children with Specific Language Impairment. The differences in vulnerable structures reflect typological properties of the surrounding language (e.g., Leonard 2014a, 2014b). This article adds a developmental perspective to the discussion by interpreting the vulnerable structures through the framework of Processability Theo

High Prevalence of Osteoporosis in Men with Distal Radius Fracture : A Cross-Sectional Study of 233 Men

Distal radius fracture is an early indicator of osteoporosis, yet little is known about men with this fracture and osteoporosis prevalence. The purpose of this cross-sectional, controlled study was to evaluate bone mineral density (BMD) in men, from working age to the elderly, with distal radius fracture. Recruitment was as follows: men who fractured during 1999–2000 were evaluated retrospectively

Respiratory Tract Infection and Risk of Hospitalization in Children with Congenital Heart Defects During Season and Off-Season : A Swedish National Study

Respiratory tract infections (RTI) are common among young children, and congenital heart defect (CHD) is a risk factor for severe illness and hospitalization. This study aims to assess the relative risk of hospitalization due to RTI in winter and summer seasons for different types of CHD. All children born in Sweden and under the age of two, in 2006–2011, were included. Heart defects were grouped

The comparative relationships between locations of the papillary muscles and electrophysiologic QRS axis in patients with atrioventricular septal defect and common as opposed to separate orifices in the valve guarding the common atrioventricular junction

Background: Knowledge regarding factors that influence deviation of the QRS axis is important when seeking to differentiate between physiological and pathological changes. We hypothesised that, in contrast to those patients with an atrioventricular septal defect and common atrioventricular junction permitting only atrial shunting, those associated with ventricular shunting would show no relationsh

Heart failure and levels of other comorbidities in patients with chronic obstructive pulmonary disease in a Swedish population : A register-based study

Background: Despite the fact that heart failure and chronic obstructive pulmonary disease (COPD) often exist together and have serious clinical and economic implications, they have mostly been studied separately. Our aim was to study prevalence of coexisting heart failure and COPD in a Swedish population. A further goal was to describe levels of other comorbidity and investigate where the patients

Who experiences higher and increasing breathlessness in advanced cancer? The longitudinal EPCCS Study

Purpose: Breathlessness is a major cause of suffering in advanced cancer. We aimed to determine the symptom trajectory in people with advanced cancer and to identify those at increased risk of experiencing higher or increasing breathlessness over time in advanced cancer. Patients and methods: This was an analysis of the multinational, prospective, longitudinal European Palliative Care Cancer Sympt

The influence of external forcing on subdecadal variability of regional surface temperature in CMIP5 simulations of the last millennium

We use Granger causality to investigate the influences of external forcings on subdecadal variability of regional near-surface air temperature (SAT) in past millennium simulations (period 850–1850 A.D.) of the Coupled Model Intercomparison Project Phase 5 (CMIP5) models. Our results strengthen the conclusion for robust influence of volcanic forcing on SAT during preindustrial times of the last mil

Increased polyamine formation in rat salivary glands by stimulation of their autonomic nerve supply

Ornithine decarboxylase (ODC), a key enzyme in polyamine biosynthesis, was measured in the three major salivary glands of rats and mice. Enzyme activity and glandular putrescine content increased after continuous stimulation of the parasympathetic or sympathetic salivary nerves for 3 h. The activity was markedly reduced in animals fasted for 24 h to decrease nervous-reflex activation of the glands
