We describe the implementation of a biochemical model of isoprene emission that depends on the electron requirement for isoprene synthesis into the Farquhar-Ball-Berry leaf model of photosynthesis and stomatal conductance that is embedded within a global chemistry-climate simulation framework. The isoprene production is calculated as a function of electron transport-limited photosynthesis, interce
Background: Management of severe aortic stenosis (AS) has evolved over the past decade, driven by the widespread adoption of transcatheter aortic valve implantation (TAVI). This study aims to assess trends in procedural volumes, patient characteristics, and outcomes for patients undergoing TAVI or surgical aortic valve replacement (SAVR) in Sweden. Methods: This was a descriptive, non-comparative,

Co-ordination of breathing and swallowing is essential for normal pharyngeal function and to protect the airway. To allow for safe passage of a bolus through the pharynx, respiration is interrupted (swallowing apnoea); however, the control of airflow and diaphragmatic activity during swallowing and swallowing apnoea are not fully understood. Here, we validated a new airflow discriminator for detec
This book analyses, in an international comparative context, Portugal´s energy transition from organic sources to fossil fuels in the period 1856-2006. It investigates the role that energy played in the industrialization of the country and how the relationship between energy and economic growth changed with the transition from an industrial to a service society. A unique dataset of energy quantiti
Objective . Low density lipoprotein cholesterol (LDL-C) is an independent and modifiable risk factor for development of cardiovascular disease (CVD). Postprandial lipid metabolism has been linked to CVD, but little is known about the postprandial LDL-C profile in patients with type-2 diabetes (T2DM). We aimed to study the postprandial levels of LDL-C in T2DM patients. Material and methods . After
Background The purpose of these studies was to compare efficacy and toxicity of docetaxel alone with the combination of gemcitabine and docetaxel for treatment of metastatic esophageal carcinoma. Patients and methods These studies enrolled patients with histopathologically verified squamous cell carcinoma or adenocarcinoma of the esophagus or cardia. Between March 1997 and June 1999, 52 patients w
The present study collected and analyzed flow boiling data points which fall in the annular flow regime with an increasing heat transfer coefficient h - vapor quality x trend (h increases with increasing x) in small diameter channels (0.1 < dh < 3.1 mm) for halogenated refrigerants, CO2 and water. In this annular flow regime, heat transfer coefficient also depends on both heat flux and mass flux.
The Mediterranean Sea has been identified as one of the hotspots for climate change. Intense warming in the Mediterranean Sea may have strong implications for biological activity and ecosystem functioning. To elucidate the effects of warming on planktonic and benthic metabolism, we performed experiments under different increasing temperature regimes, ranging from three to six different temperature
PURPOSE: The aim of this study was to test a model proposing that the relationship between personality factors and women's quality of life (QoL) is mediated by degree of depression and the way in which every day activity and general health were appraised. Specifically, the paper addressed the mediating contribution of activity. METHODS: A sample of 488 women, 38 or 50 years old, filled out questio
Changes in farming practices over the past century have had negative influence on farmland biodiversity. Organic farming excludes most agrochemicals, such as inorganic fertilisers and synthetic pesticides, and can be an alternative to conventional farming. A recent meta-analysis indicates that there is on average 30% higher species richness on organically managed farmland compared to conventionall
Background: As part of a larger study whose objective is to develop an abbreviated version of the EORTC QLQ-C30 suitable for research in palliative care, analyses were conducted to determine the feasibility of generating a shorter version of the 4-item emotional functioning (EF) scale that could be scored in the original metric. Methods: We used data from 24 European cancer studies conducted in 10
Introduction and hypothesis: Bilateral pelvic nerve injury (BPNI) is a model of post-radical hysterectomy neuropraxia, a common sequela. This study assessed the time course of changes to detrusor autonomic innervation, smooth muscle (SM) content and cholinergic-mediated contraction post-BPNI. Methods: Female Sprague–Dawley rats underwent BPNI or sham surgery and were evaluated 3, 7, 14, and 30 day
Does sertraline provide symptomatic relief for chronic breathlessness in people with advanced disease whose underlying cause(s) are optimally treated?223 participants with chronic breathlessness (modified Medical Research Council breathlessness scale ≥2) who had optimal treatment of underlying cause(s) were randomised 1:1 to sertraline 25-100 mg (titrated upwards over 9 days) or placebo for 4 week
BACKGROUND: Fine-needle aspiration cytology (FNAC) is gaining increased popularity in the diagnosis of musculoskeletal lesions; and, in many patients, a definitive diagnosis can be rendered from aspiration smears alone. The main limitation of FNAC of soft tissue and bone neoplasms is in the evaluation of tissue architecture. In addition cytologic specimens are not always adequate for ancillary stu
Objective The aim of this study was to explore the relation between the risk of first-ever stroke at working age and psychological work environmental factors. Methods A consecutive multicenter matched 1:2 case-control study of acute stroke cases (N=198, age 30-65 years) who had been working full-time at the time of their stroke and 396 sex- and age-matched controls. Stroke cases and controls answe
All-polymer blends are promising materials for organic electronics. Their performance critically depends on the quality of mixing of the electron donor and acceptor polymers and on the local chain organization. We investigated spatially resolved photoluminescence properties of as-prepared and annealed blends of poly[2,3-bis(3-octyloxyphenyl)quinoxaline-5,8-diyl-alt-thiophene-2,5-diyl] (TQ1) and po
The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional s
Background Little is known about the long-term outcome of anorexia nervosa.Aims To study the 30-year outcome of adolescent-onset anorexia nervosa.Method All 4291 individuals born in 1970 and attending eighth grade in 1985 in Gothenburg, Sweden were screened for anorexia nervosa. A total of 24 individuals (age cohort for anorexia nervosa) were pooled with 27 individuals with anorexia nervosa (ident
Mänskliga aktiviteter påverkar den biologiska mångfalden genom en mängd olika aktiviteter som ofta leder till att ekosystem utarmas. Detta leder i förlängningen till stora samhällsekonomiska förluster. Det nuvarande svenska rättsliga systemet för bevarande av biologisk mångfald fokuserar på att bevara och skydda arter som är hotade och specifika områden där dessa lever. Jag ifrågasätter utgångspunHuman activities affect biological diversity in a multitude of ways,often leading to a disruption of ecosystems. In extension this results in large economic losses for the society. The present Swedish system for preservation of biodiversity focuses on conservation of species and the specific habitats of these. I want to challenge the basic premise that biodiversity is best sustained through the pr
