Many modern cell phones have built-in sensors that may be used as a resource for physics education. Amusement rides offer examples of many different types of motion, where the acceleration leads to forces experienced throughout the body. A comoving 3D-accelerometer gives an electronic measurement of the varying forces acting on the rider, but a complete description of a motion also requires measur

The Malignancy in Haemophilia Workshop Group convened a consensus working group of haematologists and oncologists to review topics related to malignancy in haemophilia. The treatment of malignant disease in this population is increasingly relevant as both outcome and lifespan continue to improve. Although adequate guidance exists for control of spontaneous bleeding episodes and of haemostasis in g

The use of gadolinium-based contrast media in pregnant or lactating women has been discouraged at many radiology departments due to the lack of knowledge of the risks for the fetus and the unwillingness to expose neonates to unnecessary drugs. In the present review the current literature and present guidelines regarding the use of gadolinium-based contrast media have been reviewed to validate the

The distribution of organic matter (OM) in soil particle-size fractions is a key process in the dynamic and persistence of soil organic carbon. In order to study the distribution of organic amendments among the different soil particle-size fractions in a semi-arid, degraded soil (a sandy loam Haplic Regosol), a 9-month-incubation experiment was carried out after the application of composted organi

Haemophilia care has undergone substantial improvements during the past 40-50 years. Early clotting factor concentrates were not sufficiently refined to enable self-administered treatment at home until the 1970s. Unfortunately, these advances led to transmission of viral diseases including HIV and hepatitis, resulting in an increased burden of morbidity and mortality, especially during the 1980s.

Prenalterol was given to twenty five patients with acute myocardial infarction. Thirteen patients (group B) had signs of cardiac decompensation while twelve (group A) had not. Ejection fraction was determined with 99mTc-labelled red blood cells before and after prenalterol (50 μg kg-1 body weight), intravenously. In group B this procedure was repeated after digitalization 2 days later. The ejectio

A mathematical model for predicting the temperature rise in transurethral laser-induced thermo-therapy for benign prostatic hyperplasia was developed. In the model an optical line source emitting light from an Nd:YAG laser isotropically was placed in the urethra. Water cooling of the urethral epithelium was modelled using a two-tube system. The relationship between the difference in outlet and inl

Nerve injuries in the upper extremity may severely affect hand function. Cutaneous forearm anaesthesia has been shown to improve hand sensation in nerve-injured patients. A blind man who lost his Braille reading capability after an axillary plexus injury was treated with temporary cutaneous forearm anaesthesia. After treatment sensory functions of the hand improved and the patient regained his Bra

OBJECTIVE: To study the relationship between cartilage integrity, assessed with [delayed Gadolinium-Enhanced Magnetic Resonance Imaging of Cartilage (dGEMRIC)] and epidemiologic risk factors for knee osteoarthritis (OA) in meniscectomized patients. METHODS: Body mass index (BMI) was calculated in 45 patients (16 women), mean age 46, who underwent an arthroscopic medial meniscectomy 1-6 years earli

A time domain method for scattering from a one-dimensional homogeneous viscoelastic slab with impedance mismatched interfaces is presented. A viscoelastic medium is characterised by a time-dependent memory function. The reconstruction of this memory function from scattering data is an important and interesting inverse problem. Special attention is paid to the transmitted field. It is shown that tr

The transcription factor, X-box Binding Protein-One (XBP1), controls the development and maintenance of the endoplasmic reticulum (ER) in multiple secretory cell lineages. We show here that Hepatocyte Nuclear Factor 4-alpha (HNF4α) directly induces XBP1 expression. Mutations in HNF4α cause Mature-Onset Diabetes of the Young I (MODYI), a subset of diabetes characterized by diminished GSIS. In mouse

The glycosaminoglycan hyaluronic acid (HA) is an important component of the extracellular matrix (ECM) in the brain. CD44 is a cell adhesion molecule that binds to HA in the ECM and is present on astrocytes, microglia and certain neurons. Cell adhesion molecules have been reported to be involved in anxiety and mood disorders. CD44 levels are decreased in the cerebrospinal fluid (CSF) of depressed

Cell penetrating peptides (CPPs) are currently used to deliver various macromolecular cargos to intracellular sites of action both in vitro and in vivo on an experimental basis. During the last few years, even more evidence has accumulated indicating that the main route of entry for most CPPs is through endocytosis rather than direct membrane penetration, as initially proposed. The specific endocy

Treatment of Mv1Lu mink lung epithelial cells with transforming growth factor-beta 1 (TGF-beta 1) prevents phosphorylation of the retinoblastoma susceptibility gene product, RB, in late G1 phase of the cell cycle, which is thought to retain RB in a growth-suppressive state. This effect is paralleled by cell cycle arrest in late G1 (M. Laiho, J. A. DeCapric, J. W. Ludlow, D. M. Livingston, and J. M
