Graphene-Based Metal-Free Catalysis

This chapter focuses on the use of doped carbon nanomaterials in catalysis. The availability of carbon nanotubes in the ‘90s and graphene about 10Â years later, prompted the development of fundamental research and novel nanotechnologies. We discuss this topic from a point of view that links fundamental surface science to the field of catalysis, in order to present the state of the art.

Speech in 5-year-olds born with unilateral cleft lip and palate : a Prospective Swedish Intercenter Study

Studies on the impact of cleft palate surgery on speech with stringent methodology are called for, since we still do not know the best timing or the best method for surgery. The purpose was to report on speech outcome for all Swedish-speaking 5-year-olds born with a non-syndromic unilateral cleft lip and palate (UCLP), in 2008–2010, treated at Sweden’s six cleft palate centres, and to compare spee

A Colloid Approach to Self-Assembling Antibodies

Concentrated solutions of monoclonal antibodies have attracted considerable attention due to their importance in pharmaceutical formulations; yet, their tendency to aggregate and the resulting high viscosity pose considerable problems. Here we tackle this problem by a soft condensed matter physics approach, which combines a variety of experimental measurements with a patchy colloid model, amenable

Alpha-1 microglobulin as a potential therapeutic candidate for treatment of hypertension and oxidative stress in the STOX1 preeclampsia mouse model

Preeclampsia is a human placental disorder affecting 2-8% of pregnancies worldwide annually, with hypertension and proteinuria appearing after 20 weeks of gestation. The underlying cause is believed to be incomplete trophoblast invasion of the maternal spiral arteries during placentation in the first trimester, resulting in oxidative and nitrative stress as well as maternal inflammation and organ

Calprotectin in serum and zonulin in serum and feces are elevated after introduction of a diet with lower carbohydrate content and higher fiber, fat and protein contents

Calprotectin is a marker of inflammation and zonulin is a marker of intestinal permeability. Diets with lower carbohydrate content and higher contents of fat, fiber and protein, e.g., Okinawan‑based diet, are considered to reduce inflammation and intestinal permeability. The aim of the present study was to evaluate calprotectin and zonulin levels in serum and feces after intervention with an Okina

Cholecystektomy in hamster and mouse: Trophic effects on the pancreas and colon?

Cholecystectomy has been suggested to be a predisposing factor for both pancreatic and colonic cancer. We therefore investigated whether cholecystectomy caused any trophic effects on the pancreas and colon in the hamster and mouse. Cholecystectomy was performed on 13 hamsters and 11 mice. Seven of the hamsters and 6 of the mice were killed after 6 weeks, and 6 hamsters and 7 mice were killed after

French liaison in second language acquisition

This introduction to the special issue presents a brief overview of the phonological phenomenon of liaison in French, drawing on the morphosyntactic contexts of its use by native speakers. We outline previous research on liaison in second language acquisition, focusing on the challenges this phenomenon presents to learner comprehension and production, and on major findings in each area. We then pr

Analyzing savannah vegetation phenology with remotely sensed data, lagged time-series models and phenopictures

It is predicted that savannah regions will see changes in precipitation patterns due to current climate change pro-jections. The change will most likely affect leaf phenology which controls net primary production. It is thereforeimportant to; 1) study those changes and its drivers, 2) to be able to correctly model the changes to vegetationphenology due to climate change. To our knowledge there is

Cigarette smoke particles-induced airway hyperreactivity in vivo and in vitro

Cigarette smoke is a well-known strong risk factor for inducing airway hyperreactivity (AHR), but the underlying molecular mechanisms are not fully understood. In the present study, mouse in-vivo and in-vitro models were used to study effects of dimethyl sulfoxide (DMSO)-extracted cigarette smoke particles (DSP) on the airway, and to explore the underlying molecular mechanisms that are involved in

A practical guide to active stand testing and analysis using continuous beat-to-beat non-invasive blood pressure monitoring

Purpose: The average adult stands approximately 50–60 times per day. Cardiovascular responses evoked during the first 3 min of active standing provide a simple means to clinically assess short-term neural and cardiovascular function across the lifespan. Clinically, this response is used to identify the haemodynamic correlates of patient symptoms and attributable causes of (pre-)syncope, and to det

On the Small Crack Fracture Mechanics.

The limit of validity of linear fracture mechanics is specified by the minimum allowable crack length through an ASTM convention. Extension into the non-linear region ought to imply an extension towards smaller allowable Cracks. In order to elucidate the question "How short is the smallest crack that fits the methods of fracture mechanics, and how do shorter cracks than that behave?" a pilot inves

Hand injuries in an older population - A retrospective cohort study from a single hand surgery centre

Background: Hand injuries occur at all ages. With an aging population globally an increasing number of hand injuries among the elderly is to be expected. The aim of the present study is to describe the health characteristics and detailed injury patterns for elderly with hand injuries, with incidence, as a background for further studies on the topic. Specific knowledge is currently lacking about ha
