Internalization of cystatin C in human cell lines.

Altered protease activity is considered important for tumour invasion and metastasis, processes in which the cysteine proteases cathepsin B and L are involved. Their natural inhibitor cystatin C is a secreted protein, suggesting that it functions to control extracellular protease activity. Because cystatins added to cell cultures can inhibit polio, herpes simplex and coronavirus replication, which

Interaction with C4b-binding protein contributes to nontypeable Haemophilus influenzae serum resistance.

Complement evasion by various mechanisms is important for microbial virulence and survival in the host. One strategy used by some pathogenic bacteria is to bind the complement inhibitor of the classical pathway, C4b-binding protein (C4BP). In this study, we have identified a novel interaction between nontypeable Haemophilus influenzae (NTHi) and C4BP, whereas the majority of the typeable H. influe

Girls Just Wanna be Smart? The Depiction of Women Scientists in Contemporary Crime Fiction

Portrayals of fictional scientists influence how the public perceive real scientists, and fictional scientists might serve as role models as well as inspire career choices. Crime fiction is probably the most popular fiction genre today, and fictional scientists are an important presence in the genre. This is an exploratory study of three well-known contemporary women crime fiction scientists, take

The aim of this thesis is to describe the conceptual structure of space and its relationship to semantics. It is a further aim to explain differences between German and Swedish verbal expressions of space, in which one language requires a directional and the other a static prepositional phrase. This is the case with causative positional verbs, many applicative verbs, certain verbs expressing arriv

Biogas from waste materials as transportation fuel-benefits from an environmental point of view.

In this paper various biogas systems based on waste materials have been analysed from an environmental point of view. The analyses are based on Swedish conditions using a systems analysis approach from an energy and life cycle perspective. The biogas produced is used as a transportation fuel replacing petrol in light-duty vehicles. The overall aims are to quantify the potential environmental effec

An interglacial polar bear and an early Weichselian glaciation at Poolepynten, western Svalbard

The recent discovery of a subfossil polar bear (Ursus maritimus) jawbone in the Poolepynten coastal cliff sequence, western Svalbard, and its implications for the natural history of the polar bear motivated an effort to better constrain the environmental history and age envelope of the Poolepynten sediment sequence. The focus of the present study is on the lithostratigraphy of the coastal cliffs a

Human TRPA1 is intrinsically cold- and chemosensitive with and without its N-terminal ankyrin repeat domain.

We have purified and reconstituted human transient receptor potential (TRP) subtype A1 (hTRPA1) into lipid bilayers and recorded single-channel currents to understand its inherent thermo- and chemosensory properties as well as the role of the ankyrin repeat domain (ARD) of the N terminus in channel behavior. We report that hTRPA1 with and without its N-terminal ARD (Δ1-688 hTRPA1) is intrinsically

Linking chlorophyll biosynthesis to a dynamic plastoquinone pool.

Chlorophylls are essential cofactors in photosynthesis. All steps in the chlorophyll pathway are well characterized except for the cyclase reaction in which the fifth ring of the chlorophyll molecule is formed during conversion of Mg-protoporphyrin IX monomethyl ester into Protochlorophyllide. The only subunit of the cyclase identified so far, is AcsF (Xantha-l in barley and Chl27 in Arabidopsis).

Adipocyte Size is Associated with NAFLD Independent of Obesity, Fat Distribution, and PNPLA3 Genotype

Objective: Adipocyte hypertrophy has been suggested to be causally linked with inflammation and systemic insulin resistance. The aim of the study was to determine whether increased adipocyte size is associated with increased liver fat content due to nonalcoholic fatty liver disease (NAFLD) in humans independent of obesity, fat distribution and genetic variation in the patatin-like phospholipase do

Non-genetic risk factors and their influence on the management of patients in the clinic

The development of inhibitors is the most serious iatrogenic complication affecting patients with haemophilia. This complication is associated with impaired vital or functional prognosis, reduced quality of life and increased cost of treatment. The reasons why some patients develop antibodies to factor replacement and others do not remain unclear. It is however clear that inhibitor development res

Effects of Weight Loss, Weight Cycling, and Weight Loss Maintenance on Diabetes Incidence and Change in Cardiometabolic Traits in the Diabetes Prevention Program.

This study examined specific measures of weight loss in relation to incident diabetes and improvement in cardiometabolic risk factors.RESEARCH DESIGN AND METHODS: This prospective, observational study analyzed nine weight measures, characterizing baseline weight, short- versus long-term weight loss, short- versus long-term weight regain, and weight cycling, within the Diabetes Prevention Program (

Atrial fibrillation patients do not benefit from acetylsalicylic acid

Oral anticoagulation is the recommended treatment for stroke prevention in patients with atrial fibrillation. Notwithstanding, many patients are treated with acetylsalicylic acid (ASA) as monotherapy. Our objective was to investigate if atrial fibrillation patients benefit from ASA as monotherapy for stroke prevention. Retrospective study of patients with a clinical diagnosis of atrial fibrillatio

Social influence on route choice in a virtual reality tunnel fire

Introduction Evacuation from tunnel fire emergencies requires quick decision-making and swift action from the tunnel occupants. Social influence (SI) has been identified as an important factor in evacuation. Methods Two experimental groups were immersed into a virtual road tunnel fire. In the SI group participants saw a virtual agent moving on the shortest route to the nearest emergency exit. In

Numerical integration of elasto-plasticity coupled to damage using a diagonal implicit Runge-Kutta integration scheme

Abstract in UndeterminedThis article is concerned with the numerical integration of finite strain continuum damage models. The numerical sensitivity of two damage evolution laws and two numerical integration schemes are investigated. The two damage models differ in that one of the models includes a threshold such that the damage evolution is suppressed until a certain effective plastic strain is r
