The higher-level systematics of featherwing beetles (Coleoptera: Ptiliidae), the smallest non-parasitic insects and abundant in the world's forests, is poorly known. Based on larval morphology, the systematic relationships and internal classification are revised and analysed from a comparative, evolutionary and phylogenetic perspective. We introduce 37 morphological characters of all instars and o

Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related ecosystem services can be maintained by a few dominant species or rely on high richness remains unclear. Using a global database from 89 studies (with 1475 locations), we partition the relative importance of species richness, abundance, and dominance for

Background: Vitamin D has been suggested to prevent and improve the prognosis of several cancers, including breast cancer. We have previously shown a U-shaped association between pre-diagnostic serum levels of vitamin D and risk of breast cancer-related death, with poor survival in patients with the lowest and the highest levels respectively, as compared to the intermediate group. Vitamin D exerts

Background and Purpose- Psychosocial factors can have implications for ischemic stroke risk and recovery. This study investigated the effect of genetically determined risk of depression on these outcomes using the Mendelian randomization (MR) framework. Methods- Genetic instruments for risk of depression were identified in a discovery genome-wide association study of 246 363 cases and 561 190 cont

Aims: Recurrent pregnancy loss (RPL), defined as three consecutive miscarriages, is a multifaceted problem whose resolution needs a broad approach. In this thesis, epidemiology, immunology, treatment and obstetrical outcomes areexplored. The aims are as follows: To establish the incidence of the diagnosis of RPL in the National Patient Register (NPR) in Sweden from 2003 to 2012 (Paper I). To evalu

Aim: Many pediatric cancer patients undergo repeated bone marrow aspirations (BMAs) for diagnostic and treatment evaluation purposes. Full anesthesia is the standard of care during this procedure in high-income countries. At hospitals with low resources in low/middle-income countries many children undergo these painful procedures without sufficient pain relief. This study aimed to evaluate the use

Metastatic behavior varies significantly among breast cancers. Mechanisms explaining why the majority of breast cancer patients never develop metastatic outgrowth are largely lacking but could underlie the development of novel immunotherapeutic target molecules. Here we show interplay between nonmetastatic primary breast cancer and innate immune response, acting together to control metastatic prog

In last couple of decades the field of glycobiology has developed rapidly due to the increased understanding of glycans’ abilities to encode biological information, which may have impact on biological event and disease, such as for example tumour growth and inflammation. This development has been accompanied by an increasing focus on drug discovery revolving around a category of carbohydrate-based

The use of social media technologies in organizations has introduced novel ways of collaboration, communication, and knowledge sharing. In this respect, the present study is concerned with examining the use of one type of social media, the wiki technology, by members of several professional communities of practice to collaborate and share knowledge with each other. As such, it seeks to identify an

The automated and technologically enhanced home has been promoted in varying guises since the late 19th Century. Nowadays we hear much about smart homes in which new internet connected things are supposed to change daily domestic practices and routines. Are we really on the brink of something new? Will AI and robotic technology finally deliver the automagic home?

An efficient synthetic strategy for the asymmetric synthesis of a hexahydrodibenzofuran core structure, with a quaternary stereogenic center, emerges by employing a chiral reduction using Corey's (S)-Me-CBS-oxazaborolidine reagent followed by a Mitsunobu reaction to set the stereochemistry. A Pd-mediated intramolecular Heck reaction concludes the tricyclic core structure. Finally, a Pd/C catalyzed

A novel solid phase synthesis of tertiary amines involving iodide-induced cleavage of the N-O bond of resin bound alkoxyammonium intermediates is described. The quaternary intermediates were assembled via sequential reductive aminations followed by alkylation. Cleavage from the solid support was induced by iodide ion or base, to afford the target tertiary amines in excellent purity.

Purpose: To understand if physical therapy in addition to individualized psychiatric specialist treatment could aid sedentary patients with schizophrenia spectrum disorders or affective spectrum disorders to become more physically active and also to identify assessments suitable for measuring physical activity, physical function and movement motivation. Materials and methods: In a longitudinal, cl

Känner du till Caloplaca monacensis och vet hur man skiljer den från dess närmaste släktingar? Om inte så har du chansen att lära känna arten lite bättre genom denna artikel.

Double U-pipe boreholes are the second most used type of ground heat exchangers after single U-pipe boreholes. The borehole thermal resistance is a key design and performance parameter for the double U-pipe boreholes. Another parameter that is particularly important for double U-pipe boreholes is the internal thermal resistance between the U-pipes. There is, however, a general lack of methods that
