Signaling factors involved in CNS development have been used to control the differentiation of embryonic stem cells (ESCs) into mesencephalic dopamine (mesDA) neurons, but tend to generate a limited yield of desired cell type. Here we show that forced expression of Lmx1a, a transcription factor functioning as a determinant of mesDA neurons during embryogenesis, effectively can promote the generati

The aim is to highlight the influence of patients' gender on Lyme borreliosis and especially erythema migrans (EM), focusing on exposure to tick bites, epidemiology, and the clinical picture. All studies were conducted in the county of Blekinge, located in southeastern Sweden. A prospective study was conducted in 235 individuals (women, n = 110; men, n = 125) engaged in recreational or occupationa

Hypoglycaemia is presumed to be the cause of death in about 3% of insulin-treated diabetic patients. Some of these patients suffer from hypoglycaemic brain damage, but the majority have no evident brain damage and are supposed to have died from other causes such as a cardiac arrhythmia. The putative mechanism is a hypoglycaemia-induced prolongation of the QT interval which increases the risk of ma

The present paper reviews the metabolic basis of different methods for fermentative glycerol production. The most important microbial production organism is the yeast Saccharomyces cerevisiae but other yeast species, as well as molds, algae, and bacteria are of potential interest for glycerol production. A large variety of methods have been applied to increase the fermentative glycerol yield. The

In this paper we consider a Black and Scholes economy and show how the Malliavin calculus approach can be extended to cover hedging of any square integrable contingent claim. As an application we derive the replicating portfolios of some barrier and partial barrier options.

Digital human modelling (DHM) is commonly utilised for vehicle and workplace design in the automotive industry. More rarely are the tools applied in the health care industry, albeit having similar objectives for cost-efficiency and User-centred design processes. The paper illustrates how a DHM tool is modified and utilised to evaluate a bathing system design from caretakers' and caregivers' ergono

For several decades etiological diagnosis of patients with idiopathic mental retardation (MR) and multiple congenital anomalies (MCA) has relied on chromosome analysis by karyotyping. Conventional karyotyping allows a genome-wide detection of chromosomal abnormalities but has a limited resolution. Recently, array-based comparative genomic hybridization (array CGH) technologies have been developed

The kinetics of structure change when dispersions of two different types of lipid-based liquid-crystalline phases, one lamellar and one reversed, are mixed has been investigated using synchrotron small-angle X-ray diffraction and ellipsometry. The systems studied were (i) cubic-phase nanoparticles (CPNPs) based on glycerol monooleate (GMO) stabilized with a nonionic block copolymer, Pluronic F-127

To evaluate the ability of transvaginal Doppler examination to discriminate between different types of solid pelvic tumors, 55 women scheduled for laparotomy because of a solid pelvic mass underwent transvaginal sonographic examination, including color and spectral Doppler techniques. Arteries in the wall and core of each mass were examined. The histological diagnoses were as follows: uterine myom

Vitamin K-dependent protein S is a cofactor of activated protein C, a serine protease that regulates blood coagulation. Deficiency of protein S can cause venous thrombosis. Protein S has four EGF domains in tandem; domains 2-4 bind calcium with high affinity whereas domains 1-2 mediate interaction with activated protein C. We have now solved the solution structure of the EGF3-4 fragment of protein

Treatment of landfill leachate has gained increasing attention during recent years, and several commercial RO leachate treatment plants have been installed in, e.g., Germany, the Netherlands and Switzerland. in this investigation the influence on membrane performance when treating new types of landfill leachate was studied. Three different types of landfill leachate were included in this study: le

Prior research on temporal construal has shown that core values become more salient when people think about distant- as compared to near-future events. The present research shows that greater temporal distance of an event also results in greater moral concern. More specifically, it was found that people make harsher moral judgments of others' distant-future morally questionable behavior than near-

Lake and peat corings on three Azores islands in the central North Atlantic, resulted in the discovery of a 6000 year long lacustrine sequence in a small crater lake, Lake Caveiro, on the island of Pico. This island is dominated by Pico mountain (2351 m), Portugal's highest mountain, and the lake site is situated at 903 in asl. Two sediment profiles, one central and one littoral, were sampled. Due
