Plants have evolved under the influence of UV-B radiation and have acquired systems for monitoring it and investing appropriate resources for protection against it, i.e., filters, quenchers of radicals and reactive oxygen species, and repair systems. An hypothesis for how plants monitor radiation has been presented.

In the Alzheimer's disease (AD) brain, binding of Clq within the Cl complex, the initiating molecule of the classical complement pathway, to apoptotic cells, DNA and amyloid-beta (Abeta), the major constituent of senile plaques, can initiate complement activation. However, the extent of activation is determined by the balance between activation and inhibition. Fluid-phase complement inhibitor C4b-

Popular Abstract in Swedish Avhandlingen ger teoretiskt, juridiskt och empiriskt stöd för att genom hjälpmedelsförsörjning öka möjligheterna för människor med funktionshinder i låginkomstländer att förverkliga sina mänskliga rättigheter och minska sin fattigdom. Människor med funktionshinder är överrepresenterade bland världens fattiga. I utvecklingsländer lever mer än hälften av dem i extrem fatDeprived of human rights, more than half of all people with disabilities in developing countries live in extreme poverty. Although considered a prerequisite for equalization of opportunities, about nine out of ten of those who need assistive technologies do not have access to them. Little is known about the socioeconomic benefits of using assistive technology in low-income countries that can infor

In this study, a three-dimensional calculation method has been developed to simulate and analyze steam reforming of natural gas, and the effects on various transport processes in a duct from a compact steam reformer. The reformer conditions such as the combined thermal boundary conditions on solid walls, mass balances associated with the reforming reactions and gas permeation to/from the porous ca

House dusts, collected for detection of microorganisms in buildings, sometimes have to be stored before measurement. It is possible that continued growth of microorganisms in the stored samples will increase the levels of CFU, chemical marker, biomass etc. The aim of this investigation was to assess the influence of relative humidity on microbial growth in dust samples. We have exposed dust sample

ObjectivePediatric anxiety disorders can have a chronic course and are considered gateway disorders to adult psychopathology, but no consistent predictors of long-term outcome have been identified. A single latent symptom dimension that reflects features shared by all mental health disorders, the p factor, is thought to reflect mechanisms that cut across mental disorders. Whether p predicts outcom

Recent studies demonstrate that Black Carbon (BC) pollution in economically developing megacities remain higher than the values, which the World Health Organization considers to be safe. Despite the scientific evidence of the degrees of BC exposure, there is still a lack of understanding on how the severe levels of BC pollution affect human health in these regions. We consider information on the r

Atopic dermatitis (AD) is a clinically defined, highly pruritic, chronic inflammatory skin disease of children and adults. The diagnosis is made using evaluated clinical criteria. Disease activity is best measured with a composite score assessing both objective signs and subjective symptoms, such as SCORAD. The management of AD must consider the clinical and pathogenic variabilities of the disease

Beside its classical role as a serum effector system of innate immunity, evidence is accumulating that complement has an intracellular repertoire of components that provides not only immune defense, but also functions to maintain cellular homeostasis. While complement proteins, mainly the central component C3, have been detected in B cells, their exact function and source remain largely unexplored

Abstract in UndeterminedIn this paper we describe and reflect upon a novel methodology using attention cards to facilitate communication, concentration and creativity in a user requirement workshop with seniors. Previous research indicates that seniors tend to lose focus and start cross talking during workshops, which results in broad and shallow findings. However, our findings indicate that the u

Identifying optimal inspection and repair strategies for offshore jacket structures is a challenging task. We present an approach, which is based on recent developments in the field of risk-based operation and maintenance planning at the structural system level. The approach utilizes heuristics to define inspection and repair strategies at the system level and to reduce the search space of possibl

Over the last decade, Unmanned Aerial Vehicles (UAVs) have been used for monitoring construction and operation of civil infrastructure, as well as industrial facilities and power plants. Their operational simplicity along with time-and-cost-related benefits have already rendered them attractive for structural surveying. Nevertheless, the field of UAV research currently lacks a targeted employment

A software prototype is developed for assessing and updating the reliability of single-cell prestressed concrete box girders subjected to chloride-induced reinforcement corrosion. The underlying system model consists of two integrated sub-models: a condition model for predicting the deterioration state of the box girder and a structural model for evaluating the overall system reliability. The cond

This paper discusses the results from recent archaeological investigations at the Monastery of St Antony in Egypt, including the remains of a number of building phases predating the current church, locally produced pottery, and manuscript fragments written in Coptic, Arabic, Hebrew, and Ge’ez.

BACKGROUND: Ischemic preconditioning (IPC) protects the heart from prolonged ischemic insult and reperfusion injury through a poorly understood mechanism. Post-translational modifications of histone residues can confer rapid and drastic switches in gene expression in response to various stimuli, including ischemia. The aim of this study was to investigate the effect of histone methylation in the r
