Tropical forest loss and transformation to agroecosystems have serious impacts on biodiversity, associated ecosystem services and the livelihood of local people. The high crop plant biodiversity and low intensity management in many homegardens could play an important role in the preservation of biodiversity in modified landscapes, as well as sustain food security of low income households. In this

SiC nanowire based electronics hold promise for data collection in harsh environments wherein conventional semiconductor platforms would fail. However, the full adaptation of SiC nanowires as a material platform necessitates strict control of nanowire crystal structure and orientation for reliable performance. Toward such efforts, we report the growth of hexagonal phase SiC nanowire arrays grown w

The reconstruction of droughts is essential for the understanding of past drought dynamics and can help evaluate future drought scenarios in a changing climate. This article presents a reconstruction of summer droughts in France based on annually resolved, absolutely dated chronologies of oxygen isotope ratios (δ18O) in tree ring cellulose from Quercus spp. Samples were taken from living trees and

Background: The consumption of sugar-sweetened beverages (SSBs), which has increased substantially during the last decades, has been associated with obesity and weight gain. Objective: Common genetic susceptibility to obesity has been shown to modify the association between SSB intake and obesity risk in 3 prospective cohorts from the United States. We aimed to replicate these findings in 2 large

Risk factors of stroke/thromboembolism (TE) and major bleeding, and incidence of these events in specific age categories in warfarin-treated patients with mechanical heart valves (MHV) are uncertain. Our objective was to calculate event rates in specific age categories and identify risk factors for adverse events. Methods and results We identified 4,810 treatment periods with MHV between January 2

Aims In adults with coarctation of the aorta (CoA), hypertension (HTN) is a common long-term complication. We investigated the prevalence of HTN and analyzed factors associated with HTN. Methods and results In the national register for congenital heart disease, 653 adults with repaired CoA were identified (mean age 36.9 ± 14.4 years); 344 (52.7%) of them had HTN, defined as either an existing diag

Background Breast-conserving surgery (BCS) followed by radiotherapy (RT) is an established treatment for women with T1-2N0 breast cancers. Since subgroups of patients have low ipsilateral breast tumour recurrence (IBTR) rates, it is important to study whether RT is necessary for all patients. Patients and methods A total of 1187 women with primary T1-2N0M0 breast cancer were randomised, after stan

The Swedish radiologist Torsten Almén is the first clinical radiologist ever to have made a fundamental contribution to intravascular contrast medium design, the development of non-ionic contrast media. He became emotionally triggered by the patients' severe pain each time he injected the ionic "high-osmolar" contrast media when performing peripheral arteriographies in the early 1960s. One day he

Summary: Spouses tend to share habits and therefore have an increased risk of same diseases. We followed all married couples in Sweden, born 1902 to 1942, in hospital records from 1987 to 2002, and found that individuals whose spouse had a hip fracture had an increased risk of hip fracture. Introduction: The purpose of this study was to determine whether spouses of hip fracture patients have an el

Klimatsystemet påverkas av diverse externa faktorer (vulkanism, solaktivitet och förändringar i växthusgaskoncentration) och dess eget interna klimatvariabilitet. När man utvärderar orsakerna till tidigare klimatförändringar är det viktigt att öka vår kunskap om påverkan från externa faktorer samt förstå sambandet mellan de större interna faktorer som styr klimatet för att kunna förutsäga framtidaThe climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. While evaluating the causes of past climate change is important to expand our knowledge of the impacts of different external forcings, understanding the coupling between major internal climate drivers is crucial f
