Objective and methods A member of the major human cytochrome P450 superfamily of hemoproteins, CYP3A4/5, converts cholesterol into 4 beta-hydroxycholesterol. We studied plasma 4 beta-hydroxycholesterol levels prior to and 4 weeks after initiating antiretroviral therapy that included efavirenz, ritonavir-boosted atazanavir or ritonavir-boosted lopinavir with the aim of exploring the usefulness of p
Partial ion yield spectroscopy was used to study fragmentation processes in cyanogen after C 1s and N 1s photoexcitation. The interpretation of the core excitation spectrum mostly follows the literature, but the high resolution has in some cases allowed a more detailed assignment. Using the fact that in Rydberg states there is an intensity increase as the fragmentation process becomes more extensi
The management of primary gastrointestinal stromal tumours (GISTs) has evolved with the introduction of adjuvant therapy. Recently reported results of the SSG XVIII/AIO trial by the Scandinavian Sarcoma Group (SSG) and the German Working Group on Medical Oncology (AIO) represent a significant change in the evidence for adjuvant therapy duration. The objectives of this European Expert Panel meeting
In 1996 there was no convincing laboratory evidence that EMFs used in wireless communication could cause tumour promotion at non-thermal exposure levels. Therefore we then performed a study of the effects from exposure to such electromagnetic fields in the rat brain glioma model we were using in our research for brain tumour therapy. By stereotaxic technique rat glioma cells (RG2 or N32) were inje
In this article, we draw on a postcolonial sensibility to deconstruct how culture is discussed in mainstream international business textbooks. Through this deconstruction we show: (1) how the initial disclaimers that call for cultural sensitivity can be seen as pointing to the opposite of what they claim, which leads us to question the cultural sensitivity notion from ethical and political standpo
We report lifetime measurements of the five levels in the 3d(4)(a(5)D)5s e(6)D term in Cr II at an energy around 83 000 cm(-1), and log(gf) values for 38 transitions from the investigated levels. The lifetimes are obtained using time-resolved, laser-induced fluorescence on ions from a laser-produced plasma. Since the levels have the same parity as the low-lying states directly populated in the pla
Objectives: Patients with type 1 diabetes mellitus (T1DM) lack the portal/peripheral insulin gradient, which might diminish insulin stimulation of hepatic lipogenesis and protect against development of nonalcoholic fatty liver disease (NAFLD). We compared liver fat content and insulin sensitivity of hepatic glucose production and lipolysis between overweight T1DM patients and nondiabetic subjects.
Vi väntar oss att konstnärer ska vara kreativa, men erfarna konstnärer är framför allt hantverksskickliga. I allmänhet är konstnärer inte mer kreativa än andra människor. De kompletterar en tradition eller etablerad teoribildning, precis som forskare. Men till skillnad mot forskare som har ett väldefinierat problem med en given om än okänd lösning via en föreskriven metod, arbetar konstnären med ö
Säkerhet är dynamiskt och speciellt så i komplexa säkerhetskritiska verksamheter. När olyckor och incidenter är sällan förekommande i säkerhetskritiska verksamheter kan det ske en långsam och naturlig erosion av säkerhetsmedvetandet och en organisations beteenden kan börja driva mot säkerhetsmarginalerna. Säkerhetskulturen ses som en stark motriktad kraft i ett sådant händelseförlopp. Att organisa
Mixed findings have been made with regard to the long-term predictive validity of antisocial personality disorder (ASPD) on criminal behaviour in samples of substance abusers. A longitudinal record-linkage study of a cohort of 1052 drug abusers admitted 1977-1995 was undertaken. Subjects were recruited from a detoxification and short-term rehabilitation unit in Lund, Sweden, and followed through c
The article provides with an overview over female sociability in eighteenth century Sweden.

Von Willebrand factor (VWF) is an abundant plasma glycoprotein involved in platelet adhesion and aggregation at sites of vascular injury. ADAMTS13 is the sole physiological VWF-cleaving protease, thus regulating the size of thrombus growth. Dysfunctional ADAMTS13 leads to thrombotic thrombocytopenic purpura (TTP), which is either due to mutations (congenital TTP) or auto-antibodies (acquired TTP).
We present the results of a quantum mechanical modelling of the free carrier absorption (FCA) in semiconductor heterolayers. Elastic and inelastic scatterers are considered with emphasis on the interface defects (optical phonons) contributions to the induced photon absorption for elastic (inelastic) scatterers. Various approaches to FCA are also presented (perturbation, Green's function technique)
The Chinese tussah silkworm, Antheraea pernyi (Lepidoptera: Saturniidae) produces a rare dienoic sex pheromone composed of (E,Z)-6,11-hexadecadienal, (E,Z)-6,11-hexadecadienyl acetate and (E,Z)-4,9-tetradecadienyl acetate, and for which the biosynthetic routes are yet unresolved. By means of gland composition analyses and in vivo labeling we evidenced that pheromone biosynthesis towards the immedi
Green fluorescent protein (GFP) is frequently utilized for metal ion detection and quantification. To improve the metal binding potential of GFP, three residues (N146, F165, and L201) were substituted to histidines. Each variant responded differently upon interaction with metal ions. More than 80% of N146H, having the most accessible surface area, could bind to immobilized metal ions. However, onl
