Optimizing joint function : new knowledge and novel tools and treatments

Progressive joint destruction resulting from intra-articular bleeding is the major morbidity affecting patients with haemophilia (PWH), particularly those with inhibitors. Advances in understanding the detrimental processes set in motion by the exposure of joints to bleeding have shaped current management methods. However, to achieve optimal joint health in PWH, in addition to achieving haemostasi

Telomerase activation as a possible mechanism of action for psychopharmacological interventions.

Originally studied in relation to aging and cancer research, telomerase is now also investigated in relation to psychiatric disorders and treatments. Based on emerging clinical and preclinical data, we hypothesise that telomerase activation could represent a novel element mediating the mechanism of action of certain psychopharmacological interventions (e.g. antidepressants, lithium and antipsychot

Young stars in an old bulge: a natural outcome of internal evolution in the Milky Way

The center of our disk galaxy, the Milky Way, is dominated by a boxy/peanut-shaped bulge. Numerous studies of the bulge based on stellar photometry have concluded that the bulge stars are exclusively old. The perceived lack of young stars in the bulge strongly constrains its likely formation scenarios, providing evidence that the bulge is a unique population that formed early and separately from t

Hormone therapy and coronary heart disease risk by vasomotor menopausal symptoms.

OBJECTIVES: We examined whether the association between hormone therapy (HT) use and coronary heart disease (CHD) risk differed between women with and without vasomotor symptoms (VMS). STUDY DESIGN: We used data from a Dutch (EPOS) and Swedish (WHILA) population-based sample of 8865 women, aged 46-64 years, and free of CHD, stroke, venous thrombosis/pulmonary embolism or cancer at baseline. Data o

Cellular aging dynamics after acute malaria infection : A 12-month longitudinal study

Accelerated cellular aging and reduced lifespan have recently been shown in birds chronically infected with malaria parasites. Whether malaria infection also affects cellular aging in humans has not been reported. Here, we assessed the effect of a single acute Plasmodium falciparum malaria infection on cellular aging dynamics in travelers prospectively followed over one year in Sweden. DNA and RNA

Breakdown of Whole-brain Dynamics in Preterm-born Children

The brain operates at a critical point that is balanced between order and disorder. Even during rest, unstable periods of random behavior are interspersed with stable periods of balanced activity patterns that support optimal information processing. Being born preterm may cause deviations from this normal pattern of development. We compared 33 extremely preterm (EPT) children born at < 27 weeks of

Haemophilia B : Where are we now and what does the future hold?

Research has been lacking on the natural history, complications, and treatment of haemophilia B, which is less common than haemophilia A and was recognized as a distinct clinical entity in 1947. Although the two diseases share the same clinical manifestations, they differ in causative mutation, risk of inhibitor development, and patient quality of life. Frequently debated is whether haemophilia B

Dietary patterns as identified by factor analysis and colorectal cancer among middle-aged Americans

Background: Although diet has long been suspected as an etiological factor for colorectal cancer, studies of single foods and nutrients have provided inconsistent results. Objective: We used factor analysis methods to study associations between dietary patterns and colorectal cancer in middle-aged Americans. Design: Diet was assessed among 293 615 men and 198 767 women in the National Institutes o

Hur kan vi förklara framväxten av utländska banker i Kina, samt dess inverkan på Kinas ekonomi?

Syftet med denna uppsats var att kartlägga utländska bankers utveckling i Kina samt att studera dess effekter på den kinesiska ekonomin. Uppsatsen är kronologiskt indelad och börjar då de utlänska bankerna gjorde sina första inträden på den kinesiska marknaden under andra hälften av 1800-talet och forsätter in till mitten av 2000-talet. Beskrivningen sker med hjälp av en löpande diskussion av makr

End-to-end deadlines over dynamic topologies

Despite the creativity of the scientific community and the funding agencies, the underlying model of computation behind IoT, WSN, cloud, edge, fog, and mist is fundamentally the same; Computational nodes which are dynamically interconnected to form a system in where both processing capacity and connectivity may vary over time. On top of such a system, we consider applications that need packets to

HoloScale: horizontal and vertical scaling of cloud resources

Elastic and scalable compute resources are a fundamental part of cloud computing. Efficient management of cloud resources is crucial in order to provide high quality services and applications. In this work we present a novel method for scaling cloud resources and provide stability guarantees.

Template-assisted vapour–liquid–solid growth of InP nanowires on (001) InP and Si substrates

We report on the synthesis of vertical InP nanowire arrays on (001) InP and Si substrates using template-assisted vapour–liquid–solid growth. A thick silicon oxide layer was first deposited on the substrates. The samples were then patterned by electron beam lithography and deep dry etching through the oxide layer down to the substrate surface. Gold seed particles were subsequently deposited in the
