Stimulating effect of pancreatic-like enzymes on the development of the gastrointestinal tract in piglets

Use of nutritional components from the milk and eventually from the solid feed relates to the growth and development of gastrointestinal tract (GIT). We studied the effect of pancreatic-like enzymes [porcine pancreatic enzymes (Creon) or microbial-derived amylase, protease, and lipase] on GIT morphology and lipid absorption in suckling piglets. Both enzyme preparations, in low or high dose, were f

Comparison between SMOS Vegetation Optical Depth products and MODIS vegetation indices over crop zones of the USA

The Soil Moisture and Ocean Salinity (SMOS) mission provides multi-angular, dual-polarised brightness temperatures at 1.4 GHz, from which global soil moisture and vegetation optical depth (tau) products are retrieved. This paper presents a study of SMOS' tau product in 2010 and 2011 for crop zones of the USA. Retrieved tau values for 504 crop nodes were compared to optical/IR vegetation indices fr

Gestational Age at Birth and Mortality in Young Adulthood EDITORIAL COMMENT

Preterm birth is associated with increased rates of neonatal and infant mortality. It has been hypothesized that gestational age at birth may also be associated with increased mortality rates in adulthood, but to date, no studies have demonstrated this relationship. This national cohort study investigated the association between gestational age at birth and mortality in young adulthood. Data obtai

Quantification of left-to-right shunt through patent ductus arteriosus by colour Doppler in children admitted for a device closure

Purpose: Our animal model suggests that quantification of ductal flow from colour Doppler pixels is possible. We aimed to clarify whether this method can be used to determine a clinically significant ductal shunt in children. Methods: We retrospectively quantified ductal flow from saved images from 20 children who had been admitted for device occlusion of patent ductus arteriosus. Colour Doppler i

Sex-Specific Patterns of Aging in Sexual Ornaments and Gametes

Sex differences in age-dependent mortality and reproductive success are predicted to drive the evolution of sexually dimorphic patterns of reproductive investment over life. However, this prediction has not been fully explored because it is difficult to measure primary and secondary sexual traits over the life spans of males and females. Here we studied a population of fowl, Gallus gallus, to gain

Working conditions, health and productivity among dentists in Swedish public dental care - a prospective study during a 5-year period of rationalisation

In recent decades, comprehensive rationalisations have been implemented in public dentistry in Sweden. How rationalisations affect working conditions, health and production from a long-term perspective has been poorly investigated. This study aims to analyse changes and associations in dentists' working conditions, health and productivity during a 5-year period. In 2003 and 2008, 65 dentists respo

Staphylococcal Proteases Aid in Evasion of the Human Complement System.

Staphylococcus aureus is an opportunistic pathogen that presents severe health care concerns due to the prevalence of multiple antibiotic-resistant strains. New treatment strategies are urgently needed, which requires an understanding of disease causation mechanisms. Complement is one of the first lines of defense against bacterial pathogens, and S. aureus expresses several specific complement inh

Clickable molecularly imprinted nanoparticles.

Terminal alkynyl and azide groups are introduced on the surface of molecularly imprinted core-shell nanoparticles using precipitation polymerization. These clickable groups enable simple nanoparticle conjugation and surface modification under mild reaction conditions, opening new opportunities for nanoparticle-based assays and chemical sensing.

Molecular mechanisms of Streptococcus dysgalactiae subsp equisimilis enabling intravascular persistence

Streptococcus dysgalactiae subsp. equisimilis (SDSE) can cause recurrent bacteremic infection. We have characterized novel virulence properties of an SDSE isolate of type stG485.0 that caused severe sepsis three times in a patient despite that he had opsonizing antibodies to the isolate. An infected aortic aneurysm was suspected to be the focus for the persisting bacteria. For the first time we sh

Combined assessment of sex- and mutation-specific information for risk stratification in type 1 long QT syndrome

BACKGROUND Men and women with type 1 long QT syndrome (LQT1) exhibit time-dependent differences in the risk for cardiac events. OBJECTIVE We hypothesized that sex-specific risk for LQT1 is related to the location and function of the disease-causing mutation in the KCNQ1 gene. METHODS The risk for life-threatening cardiac events (comprising aborted cardiac arrest [ACA] or sudden cardiac death [SCD]

Derivative backoff: The other saturation problem for PID controllers

tThe PID controller is by far the most common controller, and to ensure good behavior under all circumstances, a PID implementation must consider many practical aspects such as integrator windup,derivative kick, and bumpless parameter and mode changes. In this paper, an entirely new issue for the derivative part is introduced and has been named derivative backoff. It occurs when the process value

Acuity and Anxiety From the Patient's Perspective in the Emergency Department.

Knowledge of a patient's perception of her medical needs and urgency may make it possible for emergency nurses to communicate the triage decision and make the patient understand the assessment and triage category. The aim of this study was to compare the patients' own assessments of their acuity to the triage nurse's assessment, as well as describe patient satisfaction and levels of anxiety.

Implementation of robot-assisted gynecologic surgery for patients with low and high BMI in a German gynecological cancer center.

Purpose To present a single center outcome from an initial series of gynecological robotic cases with a special reference to obese patients. Methods A retrospective evaluation of 116 women, undergoing elective gynecologic robot-assisted surgery from February 2011 to December 2012. Procedures included hysterectomy (HE), radical HE, adnexectomy, myomectomy, pelvic lymphadenectomy and paraaortic lymp

Characterization of volatile components extracted from Vangueria infausta (African medlar) by using GC-MS

Volatile compounds isolated from the African medlar (Vangueria infausta L.) were identified by gas chromatography and gas chromatography-mass spectrometry. The volatile components identified in the extract were: hexanoic acid (5600 mu g/g, dry matter, DM), octanoic acid (240 mu g/g, DM), methyl hexanoate (15 mu g/g, DM), ethyl hexanoate (44 mu g/g, DM), methyl octanoate (12 mu g/g, DM) and ethyl o

The Role of Neuropeptides in Suicidal Behavior: A Systematic Review

There is a growing evidence that neuropeptides may be involved in the pathophysiology of suicidal behavior. A critical review of the literature was conducted to investigate the association between neuropeptides and suicidal behavior. Only articles from peer-reviewed journals were selected for the inclusion in the present review. Twenty-six articles were assessed for eligibility but only 22 studies

Stepping stone or stumbling block? : Mode 2 knowledge production in sustainability science

The concept of Mode 2 was developed in order to further our understanding of processes of knowledge production taking place between and beyond disciplinary structures (inter- and transdisciplinary processes) and “in a context of application”. The concept has often been seen as especially applicable to fields addressing grand challenges, such as cli- mate change, poverty eradication, and global hea
