Microarrays based on affinity-tagged single-chain Fv antibodies: Sensitive detection of analyte in complex proteomes

Protein-based microarrays are among the novel class of rapidly emerging proteomic technologies that will allow us to efficiently perform global proteome analysis. However, the process of designing adequate protein microarrays is a major inherent problem. In this study, we have evaluated a protein microarray platform based on nonpurified affinity-tagged single-chain (sc) Fv antibody fragments to ge

Granola bars prepared with Agave tequilana ingredients: Chemical composition and in vitro starch hydrolysis

The stem of Agave tequilana is used to obtain: agave syrup (AS) and native agave fructans (NAF). Ground-agave-fiber is the by-product from fructans production. These ingredients were used to design a food ingredient: agave dietary fiber (ADF), containing NAF (30 g/100 g) as soluble dietary fiber (DF) and ground-agave-fiber (70 g/100 g) as an insoluble DF. The objective of this work was to evaluate

Propagation channel models for next-generation wireless communications systems

As new systems and applications are introduced for next-generation wireless systems, the propagation channels in which they operate need to be characterized. This paper discusses propagation channels for four types of next-generation systems: (i) distributed Multiple-Input Multiple-Output (MIMO) and Cooperative MultiPoint (CoMP), systems, which require the characterization of correlation between c

Searching for new convolutional codes using the cell broadband engine architecture

The Bidirectional Efficient Algorithm for Searching code Trees (BEAST), which is an algorithm to efficiently determine the free distance and spectral components of convolutional encoders, is implemented for the Cell Broadband Engine Architecture, efficiently utilizing the underlying hardware. Exhaustive and random searches are carried out, presenting new rate R=1/2 convolutional encoding matrices

Financialisation, sustainability and the right to the island: a critique of acronym models of island development

The penetration of financialization into the biocultural geographies of islands builds upon processes of commodification and privatization of environments, entailing enclosures of resource commons, environmental destruction and displacement of people, their livelihoods, knowledge and practices, with implications for sustainability. Against this background I critique the growing literature on acron

Determinants of left atrial reverse remodeling after valve surgery for degenerative mitral regurgitation.

Left atrial (LA) enlargement is a pathophysiological response to volume overload resulting from chronic mitral regurgitation (MR), is known as LA remodeling, and has been shown previously to be associated with cardioembolic events. Following mitral valve surgery (MVS), the left atrium may undergo reverse remodeling characterized by LA volume reduction. The study aim was to evaluate the incidence a

OER, Resources for learning – Experiences from an OER Project in Swede

This article aims to share experience from a Swedish project on the introduction and implementation of Open Educational Resources (OER) in higher education with both national and international perspectives. The project, OER – resources for learning, was part of the National Library of Sweden Open Access initiative and aimed at exploring, raising awareness of and disseminating the use of OER and th

Resistant starch in common starchy foods as an alternative to increase dietary fibre intake

Nutritional classification of dietary saccharides considers as indigestible saccharides those that are incompletely or not absorbed in small intestine. Resistant starch (RS) as a part of dietary fibre (DF) is a type of indigestible saccharide. The addition of natural RS from some fruits, legumes or cereals to commonly eaten starchy foods is a good alternative to increase the DF intake representing

Design of Reconfigurable Hardware Architectures for Real-time Applications

This thesis discusses modeling and implementation of reconfigurable hardware architectures for real-time applications. The target application in this work is digital holographic imaging, where visible images are to be reconstructed based on holographic recordings. The reconstruction process is computationally demanding and requires hardware acceleration to achieve real-time performance. Thus, this

Phototoxicity of pyrene affects benthic algae and bacteria from the arctic

Phototoxicity of polycyclic aromatic hydrocarbons (PAHs) in the Arctic is important to study since the future PAH load is likely to increase. In combination with the increased UV-Iight penetration due to ozone layer thinning, phototoxicity may be a potential problem for arctic areas. The aim of this study was to evaluate effects of pyrene and phototoxicity of pyrene on natural algae and bacteria f

Effect of Humic Substance Photodegradation on Bacterial Growth and Respiration in Lake Water

This study addresses how humic substance (HS) chemical composition and photoreactivity affect bacterial growth, respiration, and growth efficiency (BGE) in lake water. Aqueous solutions of HSs from diverse aquatic environments representing different dissolved organic matter sources (autochthonous and allochthonous) were exposed to artificial solar UV radiation. These solutions were added to lake w

Enhanced efficacy of porcine lung surfactant extract by utilization of its aqueous swelling dynamics.

This study investigates the interactions between a porcine lung surfactant (PLS) extract and distilled water, saline solution or Ringer solution. The phases which coexist in equilibrium with water or electrolyte solutions were analysed by X-ray diffraction and cryo transmission electron microscopy (cryo-TEM). A lamellar phase with a structure unit consisting of double bilayers was observed in wate

Exploring the meaning of everyday life, for those suffering from dementia

Living with dementia means struggling to preserve a sense of self, to retain (and reevaluate) one's values in a new situation, and to search for a new way of life. This study explored the meaning of everyday life as expressed by 11 people suffering from dementia. Data were collected through interviews with people in the early stage of a diagnosed dementia disease. The findings indicate that many p

The meaning of fatigue for women with multiple sclerosis

Aim. This paper reports the findings of a study that aimed to elucidate the meaning of fatigue for women with multiple sclerosis (MS). Background. Living with chronic illness can involve giving up usual activities. MS is a chronic autoimmune disease of the central nervous system. Fatigue is a common experience among people with MS; however, little is known about the meaning of fatigue experienced

A hypothesis-generating search for new genetic breast cancer syndromes - a national study in 803 Swedish families

Among Swedish families with an inherited predisposition for breast cancer, less than one third segregate mutations in genes known to be associated with an increased risk of breast cancer in combination with other types of tumours. In a search for new putative familial breast cancer syndromes we studied Swedish families undergoing genetic counselling during 1992-2000. Four thousand families from co

Brain damage and hypoxia in an ovine fetal chronic cocaine model
