Many Gram-positive bacteria express surface proteins that bind human plasma proteins. These bacterial proteins, and derivatives of them, are of interest for analysis of bacterial pathogenesis and as immunochemical tools. Well-characterized examples include the IgG-binding reagents staphylococcal protein A and streptococcal protein G, and the recently described streptococcal IgA-binding peptide Sap

A diminished capacity to maintain tissue homeostasis is a central physiological characteristic of ageing. As stem cells regulate tissue homeostasis, depletion of stem cell reserves and/or diminished stem cell function have been postulated to contribute to ageing. It has further been suggested that accumulated DNA damage could be a principal mechanism underlying age-dependent stem cell decline. We

This thesis examines the role of sunlight, specifically ultraviolet-B radiation (280-320 nm), on dissolved organic matter (DOM) and bacteria in lakes. Field experiments in lakes with different humic contents and geographical locations have been performed. Photooxidation result in that part of DOM is oxidized to inorganic carbon (DIC), mainly CO2. The photooxidation rate can be of the same magnitu

In the Tunisian semiarid area, water erosion processes have led to negative economic and environmental consequences in a context of limited water resources. To characterize and predict these degradation phenomena, a comprehensive high-resolution data base on erosive rainfall, together with siltation records for 28 small reservoirs were analyzed. The studied small reservoir network displays a gener

A number of studies stress the importance of positive mealtime experiences for nursing home residents. However, the components that comprise an ideal nursing home meal remain unclear, reflecting the ambiguity of whether nursing homes should be framed as institutions, domestic settings or a type of hotel. In this study, nursing home meals were viewed as situations that the involved parties could co

The spontaneous open-field behavioural effects of 10 days of chronic treatment with two clinical doses (10 and 20 mg/kg daily) and one high/toxic dose (100 mg/kg daily) of the selective serotonin reuptake inhibitor citalopram (delivered subcutaneously by implanted osmotic pumps) were examined in rats. Central and peripheral arena locomotor and rearing activities were recorded simultaneously, and t

Resonant photoemission involving dissociative core excited states has been the subject of a great number of experimental and theoretical investigations in recent time. The resonant decay of such dissociating systems has been shown to lead to semiatomic Auger electron emission spectra, with particular angular behavior. In the present paper a detailed theoretical analysis of dissociative resonant ph

Adenoviral vector mediated gene delivery has been applied in clinical trials and mechanistic studies to explore new treatment approaches for lung cancers. The expression of coxsackievirus adenovirus receptor (CAR), the primary receptor for the most commonly used adenovirus serotype 5 (Ad5)-based vectors, predominantly determines the permissiveness of lung cancer cells. CAR expression is also sugge

Because low genetic diversity may threaten the viability of isolated populations, conservation biologists have devoted much effort to quantify genetic variation. Two techniques routinely used involve levels of mini- and microsatellite polymorphism, with the assumption that levels of variation at these parts of the genome will be reflected in levels of variation at other loci. Our data challenge th

Objective. Heredity is a major cause of ovarian cancer and during recent years the contribution from germline mismatch repair (MMR) gene mutations linked to Lynch syndrome has gradually been recognized. Methods. We characterized clinical features, tumor morphology and mismatch repair defects in all ovarian cancers identified in Swedish and Danish Lynch syndrome families. Results. In total, 63 epit

I Sverige har inte barn som bevittnat våld i nära relation målsägandestatus, d.v.s. straffrättslig status som brottsoffer, något som kritiserats av FN:s barnkommitté. Ett barn som har bevittnat våld i nära relation ses med dagens svenska reglering däremot som ett brottsoffer i ordets vida betydelse. Detta genom att barnet sedan 2006 har möjlighet att ansöka om s.k. bevittnandeersättning från BrOM.

An understanding of the inherent effectiveness-potential of environmental product-labels is important because of the growing presence of these labels as governance regimes, especially in the textile market. The proper governance of eco-labels has the potential to assist with the transformation to more environmentally friendly consumption, but not enough is known about the inherent qualities that m

As commodities are becoming more popular and accessible assets for speculative and hedging purposes, the limited research regarding risk management for said asset-class justifies further contribution to the deficient output. Many previous studies have highlighted the extraordinary high volatility, with non-linear and clustering characteristics associated with commodities. Hence, incorporating vola

Vikten av resurseffektivitet i livsmedelskedjan är tydlig, eftersom denna sektor är en av de största bidragarna till negativ klimatpåverkan globalt. Målet med den här uppsatsen var att utforska sidoströmmar av mat inom livsmedelskedjan i Västra Götaland, för att kartlägga hur mycket som redan är täckt i statistiken och vilka luckor i datamaterialet som finns för framtida forskning att täcka. DessThe importance of resource efficiency in the food supply chain is clear, since this sector is one of the biggest contributors to the negative environmental impacts globally. This thesis project aimed to examine food side streams throughout the food supply chain in Västra Götaland, to map out how much has already been covered statistically and what gaps there are in the data for future research to

More than 50 percent of Jamaican households are remittances receiving. Remittances generally form a source of supplemental household income by helping households cover expenses such as utilities,healthcare, education etc. Studies have focused on its reaction to economic shocks, structural changes, its use as insurance or safety net or generally just observing trends. This study employs propensity

I ABSTRACT This thesis studies a two-echelon distribution inventory system with a central depot which supplies N non-identical retailers with a single product. Stochastic customer demand occurs solely at the retailers. The purpose of the master thesis project is to evaluate the potential benefit of two methods in which the control of the inventory points in the inventory system is coordinated. The
