‘Lease the land, but use the water’ : The case of gambella, Ethiopia

Gambella is one of the regional states in Ethiopia where huge tracts of land have been leased out to domestic and international investors since the global food, fuel and financial crisis of 2007/2008. The Gambella region is also one of the most marginalized regions in Ethiopia. It has been alienated from the central politics and socio-economic activities of the state. In the past, the Gambella reg

Diffusion of biogas for freight transport in Sweden : A user perspective

Current freight transport is highly dependent on fossil fuels and there is a need for a transition to alternative fuels and technologies. Biogas is a type of biofuel that has the potential to reduce climate emissions from freight transport, while providing additional benefits such as recycling of nutrients and increased energy security. This paper uses theories on the diffusion of green technologi

The γ-tubulin meshwork assists in the recruitment of PCNA to chromatin in mammalian cells

Changes in the location of γ-tubulin ensure cell survival and preserve genome integrity. We investigated whether the nuclear accumulation of γ-tubulin facilitates the transport of proliferating cell nuclear antigen (PCNA) between the cytosolic and the nuclear compartment in mammalian cells. We found that the γ-tubulin meshwork assists in the recruitment of PCNA to chromatin. Also, decreased levels

Plastic dinosaurs : Digging deep into the accelerating carbon lock-in of plastics

The continued expansion of plastics production all over the world entrenches modern societies and life styles deeper in the dependence on fossil resources. This research note develops the main aspects of the carbon lock-in in the plastics industry and how it extends into many aspects of contemporary life. With data collected from trade press and reports, we present insights of the investment trend

IFN-β rescues neurodegeneration by regulating mitochondrial fission via STAT5, PGAM5, and Drp1

Mitochondrial homeostasis is essential for providing cellular energy, particularly in resource-demanding neurons, defects in which cause neurodegeneration, but the function of interferons (IFNs) in regulating neuronal mitochondrial homeostasis is unknown. We found that neuronal IFN-β is indispensable for mitochondrial homeostasis and metabolism, sustaining ATP levels and preventing excessive ROS b

Augmenting a dynamic hip screw with a calcium sulfate/hydroxyapatite biomaterial

Internal fixation failure in hip fractures can lead to reoperation. Calcium sulfate/hydroxyapatite (CaS/HA) is a biomaterial that can be used for augmenting fracture fixation. We aimed to determine whether an injection of 2 ml CaS/HA increases the fixation of a dynamic hip screw inserted in synthetic and human trabecular bone. The study consists of two parts: 1) synthetic bone blocks (n = 74), wit

Validation of a SIMIND Monte Carlo modelled gamma camera for Iodine-123 and Iodine-131 imaging

Purpose: Monte Carlo (MC) modelling techniques can assess the quantitative accuracy of both planar and SPECT Nuclear Medicine images. It is essential to validate the MC code's capabilities in modelling a specific clinical gamma camera, for radionuclides of interest, before its use as a clinical image simulator. This study aimed to determine if the SIMIND MC code accurately simulates emission image

Externally added cystatin C reduces growth of A375 melanoma cells by increasing cell cycle time

Some secreted cysteine protease inhibitors of the cystatin family appear to affect intracellular proteolysis and growth of human cells, as a result of internalization. Here, we studied the effects of external addition of the most abundant human cystatin, cystatin C, on viability and proliferation of cancer cells in culture. A dose-dependent decrease in viable cells was seen for A375 melanoma, MCF-

Terms, definitions and measurements to describe sonographic features of lymph nodes : consensus opinion from the Vulvar International Tumor Analysis (VITA) group

In centers with access to high-end ultrasound machines and expert sonologists, ultrasound is used to detect metastases in regional lymph nodes from melanoma, breast cancer and vulvar cancer. There is, as yet, no international consensus on ultrasound assessment of lymph nodes in any disease or medical condition. The lack of standardized ultrasound nomenclature to describe lymph nodes makes it diffi

DNA Repair Gene Polymorphisms and Chromosomal Aberrations in Exposed Populations

DNA damage and unrepaired or insufficiently repaired DNA double-strand breaks as well as telomere shortening contribute to the formation of structural chromosomal aberrations (CAs). Non-specific CAs have been used in the monitoring of individuals exposed to potential carcinogenic chemicals and radiation. The frequency of CAs in peripheral blood lymphocytes (PBLs) has been associated with cancer ri

Industrial Development in Chile. 1870 - 2015

Chile has been one of the richest Latin American countries since nineteenth century. Gifted with enormous amount of Natural Resources (NNRR), its growth is linked to the exploitation of these resources and exports related to the primary economic sector, however, besides to this lack of diversification, industrial sector has played a relevant role in this country and its development is crucial to u

Differences in Health-Related Quality of Life After Gastric Bypass Surgery : a Cross-Sectional Study

Background: Gastric bypass (GBP) is a surgical method with good evidence of sustainable weight loss, reduced obesity-related comorbidities, and improved health-related quality of life (HRQoL). However, long-term data post-GBP is scarce on HRQoL related to other factors than weight loss, such as impact of socio-economic, age, and gender. Aim: To investigate long-term HRQoL in GBP patients. Methods:

Traffic-Related Air Pollution as a Risk Factor for Dementia : No Clear Modifying Effects of APOE ϵ4 in the Betula Cohort

It is widely known that the apolipoprotein E (APOE) ϵ4 allele imposes a higher risk for Alzheimer's disease (AD). Recent evidence suggests that exposure to air pollution is also a risk factor for AD, and results from a few studies indicate that the effect of air pollution on cognitive function and dementia is stronger in APOE ϵ4 carriers than in non-carriers. Air pollution and interaction with APO

The Rise of a New Public Bureaucracy in New Zealand?

One recurrent narrative in the discussion about managerial public sector reforms is the growth in organizational professionals as a response to new accountability regimes. New Zealand has experienced modest growth rates in the general public sector workforce. Less studied, though, is whether the composition of the public sector workforce has changed, with an increase in organizational functions su
