Species Collapse via Hybridization in Darwin's Tree Finches

Species hybridization can lead to fitness costs, species collapse, and novel evolutionary trajectories in changing environments. Hybridization is predicted to be more common when environmental conditions change rapidly. Here, we test patterns of hybridization in three sympatric tree finch species (small tree finch Camarhynchus parvulus, medium tree finch Camarhynchus pauper, and large tree finch:

Urban Peacebuilding in ethno-nationally divided and contested cities: the case of Mostar

This article seeks to outline a conceptual landscape that can assist us to better grasp how urban communities torn and traumatised by violent conflicts remain divided in peace and resistant to liberal peacebuilding efforts. It suggests that peacebuilding needs to be urbanised to better address and mitigate tensions and ethnocratic spatial practices in divided cities. The urban is suggested as a pr

Treatment with beta-blockers is associated with lower levels of Lp-PLA2 and suPAR in carotid plaques.

OBJECTIVES: To determine whether a long-term treatment with beta-blockers influences the inflammatory activity in carotid artery disease by reducing the carotid plaque levels of lipoprotein-associated phospholipase A2 (Lp-PLA2), its enzymatic products lysophosphatidylcholine (lysoPCs), and of soluble urokinase plasminogen activator receptor (suPAR). MATERIALS AND METHODS: One hundred and thirty-fo

Evaluation of amylase testing as a tool for saliva screening of crime scene trace swabs.

Amylase testing has been used as a presumptive test for crime scene saliva for over three decades, mainly to locate saliva stains on surfaces. We have developed a saliva screening application for crime scene trace swabs, utilising an amylase sensitive paper (Phadebas((R)) Forensic Press test). Positive results were obtained for all tested dried saliva stains (0.5-32muL) with high or intermediate a

17 beta-Estradiol induces nongenomic effects in renal intercalated cells through G protein-coupled estrogen receptor 1

Hofmeister MV, Damkier HH, Christensen BM, Olde B, Leeb-Lundberg LM, Fenton RA, Praetorius HA, Praetorius J. 17 beta-Estradiol induces nongenomic effects in renal intercalated cells through G protein-coupled estrogen receptor 1. Am J Physiol Renal Physiol 302: F358-F368, 2012. First published October 12, 2011; doi: 10.1152/ajprenal.00343.2011.-Steroid hormones such as 17 beta-estradiol (E2) are kn

In-kind transfers of maize, commercialization and household consumption in Kenya

This article discusses in kind food transfers and whether such transfers should be interpreted as a sign of the failure of grain markets to meet the food demands of the poor. The paper elucidates on aspects of both consumption and in kind transfers of maize against a backdrop of poorly functioning markets. The paper adds to the theoretical understanding of household based linkages and provides a d

Autism spectrum disorders and coexisting disorders in a nationwide Swedish twin study

Background: Evidence from twin and molecular genetic studies is accumulating that Autism Spectrum Disorder (ASD) shares substantial etiological factors with other disorders. This is mirrored in clinical practice where ASD without coexisting disorders is rare. The present study aims to examine the range of coexisting disorders in ASD in a genetically informative cohort. Methods: Parents of all Swed

Wesseling et al. Respond.

We appreciate Ventres' observations and share his goal to reduce CKD incidence "by occupational, environmental, and health-related reforms that make this work [agricultural labor] more humane." In our summary of the workshop on the Mesoamerican nephropathy (MeN) in San José, Costa Rica, November 2012, we also noted the need for a broad understanding of the epidemic and we call readers' attention t

Modelling reactive solute transport from groundwater to soil surface under evaporation

Two-stage soil column experiments involving capillary rise and evaporation were conducted to improve understanding of salt and water movement from groundwater to soil surface. In total, 64 soil columns were placed in a tank partly filled with water in order to mimic the groundwater table in soil. Each soil column was analysed by dividing it into 27 segments to analyse pore water and ion distributi

Awakening the Sufferers: Reflections on Public Relations, Activism, and Subalternity in Postcolonial Controversies between Taiwan and Japan

This article is a qualitative analysis of mass-mediated projections of relationships between public relations practitioners in the shape of activist groups and organizations, and subaltern stakeholders for whom they act as public representatives. Drawing my empirical examples from Japan and Taiwan and analysing the public relations implications of two politically sensitive and controversial cases,

How design process for the Base of the Pyramid differs from that for the Top of the Pyramid

The base (BOP) and the top (TOP) of the world income pyramid represent the poor people and the people from developed countries, respectively. The design of products for the BOP is an important ingredient of the poverty reduction approach that combines business development with poverty alleviation. However, the current understanding of the design for the BOP is limited. This study, using a protocol

Effects of nitrogen fertilization on the forest floor carbon balance over the growing season in a boreal pine forest

Boreal forests play a key role in the global carbon cycle and are facing rapid shifts in nitrogen availability with poorly understood consequences for ecosystem function and global climate change. We quantified the effects of increasing nitrogen availability on carbon fluxes from a relatively understudied component of these forests - the forest floor - at three intervals over the summer growing pe

Gas6 is complexed to soluble tyrosine kinase receptor Axl in human blood.

Summary Background: The vitamin K-dependent Gas6 protein (product of growth arrest specific gene 6) binds to, and activates the TAM receptor tyrosine kinases Tyro3, Axl, and Mer. Gas6 and the TAM receptors have been suggested to be important for primary platelet functions, but Gas6 cannot be found in human platelets. However, Gas6 is present in human plasma at a concentration of around 0.2 nM, whi

Spatially resolved Hall effect measurement in a single semiconductor nanowire

Efficient light-emitting diodes and photovoltaic energy-harvesting devices are expected to play an important role in the continued efforts towards sustainable global power consumption. Semiconductor nanowires are promising candidates as the active components of both light-emitting diodes and photovoltaic cells, primarily due to the added freedom in device design offered by the nanowire geometry. H

Platelet shedding of CD40L is regulated by matrix metalloproteinase-9 in abdominal sepsis.

Background and objectives: Platelet-derived CD40L is known to regulate neutrophil recruitment and lung damage in sepsis. However, the mechanism regulating shedding of CD40L from activated platelets is not known. We hypothesized that matrix metalloproteinase-9 might cleave surface expressed CD40L and regulate pulmonary accumulation of neutrophils in sepsis. Methods: Abdominal sepsis was induced by
