PETRA IV : the ultralow-emittance source project at DESY

The PETRA IV project aims at upgrading the present synchrotron radiation source PETRA III at DESY into an ultralow-emittance source. Being diffraction limited up to X-rays of about 10 keV, PETRA IV will be ideal for three-dimensional X-ray microscopy of biological, chemical and physical processes under realistic conditions at length scales from atomic dimensions to millimetres and time scales down

Measuring patient-reported outcomes in haemophilia clinical research

Patient-reported outcome (PRO) measures have been used to assess quality of life and health state preferences from the patient's perspective. However, they have not been fully utilized in haemophilia clinical practice and research. A series of meetings were convened to review and document the state of the art in PROs relevant to haemophilia. Experts developed a process for selection of measures an

Hydrogeochemical evolution of groundwater in a Quaternary sediment and Cretaceous sandstone unconfined aquifer in Northwestern China

A better understanding of the hydrogeochemical evolution of groundwater in vulnerable aquifers is important for the protection of water resources. To assess groundwater chemistry, groundwater sampling was performed from different representative aquifers in 2012–2013. A Piper trilinear diagram showed that the groundwater types can be classified into Na–SO4 and Na–Cl types. Only one groundwater samp

Anaerobic co-digestion of sludge and organic food waste-performance, inhibition, and impact on the microbial community

Anaerobic co-digestion allows for under-utilised digesters to increase biomethane production. The organic fraction of municipal solid waste (OFMSW), i.e., food waste, is an abundant substrate with high degradability and gas potential. This paper investigates the co-digestion of mixed sludge from wastewater treatment plants and OFMSW, through batch and continuous lab-scale experiments, modelling, a

Combining synchrotron light with laser technology in catalysis research

High-energy surface X-ray diffraction (HESXRD) provides surface structural information with high temporal resolution, facilitating the understanding of the surface dynamics and structure of the active phase of catalytic surfaces. The surface structure detected during the reaction is sensitive to the composition of the gas phase close to the catalyst surface, and the catalytic activity of the sampl

Diachronic Atlas of Comparative Linguistics (DiACL)—A database for ancient language typology

Feature stability, time and tempo of change, and the role of genealogy versus areality in creating linguistic diversity are important issues in current computational research on linguistic typology. This paper presents a database initiative, DiACL Typology, which aims to provide a resource for addressing these questions with specific of the extended Indo-European language area of Eurasia, the regiFeature stability, time and tempo of change, and the role of genealogy versus areality in creating linguistic diversity are important issues in current computational research on linguistic typology.

Borrowability, inheritance, and semantic change in the Indo-European and Caucasian vocabulary for hunting, farming, and technology

Vocabulary for subsistence and technology may vary a great deal in their degree of borrowability, depending on time, place, inherent subsistence and technology, and the situation of the borrowing. In cross-linguistic typological studies of borrowability, these words tend to group somewhere from middle to high in borrowability, depending on lexical concept (Haspelmath & Tadmor, 2009).We have co

Why do we need loans? : A comparative-contrastive study on Eurasian lexical borrowability

Languages borrow words when there is a need for it, all languages contain loanwords, and no part of the lexicon is entirely “loan-proof”. These are statements about lexical borrowing that are typically found in linguistic textbooks (Hock and Joseph 1996). Further, we know that that there are large discrepancies in the borrowability of different lexical concepts, where core vocabulary domains (sens

How, When and Why Did the Way the EU Speaks About the Israeli-Palestinian Conflict Change?

The Israeli-Palestinian conflict, or the Israeli-Arab conflict/the conflict in the Middle East, as it was called in official EC/EU language all the way up to the 2000s, presented what was widely perceived in Europe to be a golden opportunity for the EC to unite its foreign policy in the late 1960s and early 1970s. However, as important that goal was, many European politicians—from left to right—si

Symposium in memory of Professor Inga Marie Nilsson

Professor Inga Marie Nilsson (1923-99) was a pioneer in the field of bleeding and thrombo-embolic disorders and made several major scientific contributions during her career. To honour her memory, colleagues from all over the world were invited to cover several aspects of haemostasis by giving state-of-the-art lectures at an international symposium in Malmö on September 22-23, 2000, chaired by Pro

Prenatal diagnosis of haemophilia

Prenatal diagnosis of haemophilia A or B is possible by means of chorionic villus biopsy in the first trimester which traces the mutation or informative genetic markers. If possible, direct gene analysis of the mutation is preferred, The natural starting point in haemophilia A is to ascertain whether the disease is due to inversion in the X-chromosome, which is the case in almost half of the sever

Molecular basis of factor xiii deficiency H.Mikkola

Factor XIII deficiency is a rare autosomal recessive bleeding disorder that is characterized by defective crosslinking of fibrin and poor resistance to fibrinolysis. We have characterized seven mutations in FXIII A-subunit gene: Four missense mutations (Met242->Thr. Arg252->Ile, Arg326->Gln and Leu498->Pro) and three nonsense mutations (Arg661->Stop, delT Phe8 and a splicing defect T->C at positio

Determination of factor IX allotypes for carrier identification in haemophilia B

The existence of two genetic variants (allotypes) of normal human factor IX is used for carrier detection in three families with severe and one with mild haemophilia B. By analysis of IX:Ag with two different monoclonal antibodies in 93 members of the families, allelic assignment is shown to be a complement in carrier diagnosis to genotypic DNA studies. Allelic assignment makes possible a reliable

Practical aspects of extended half-life products for the treatment of haemophilia

Haemophilia A and haemophilia B are congenital X-linked bleeding disorders caused by deficiency of coagulation factor VIII (FVIII) and IX (FIX), respectively. The preferred treatment option for patients with haemophilia is replacement therapy. For patients with severe disease, prophylactic replacement of coagulation factor is the treatment of choice; this has been shown to reduce arthropathy signi

Diagnosis and care of patients with mild haemophilia : practical recommendations for clinical management

Mild haemophilia is defined by factor levels between 0.05 and 0.40 IU/mL and is characterised by traumatic bleeds. Major issues associated with mild haemophilia are that it may not present for many years after birth, and that awareness, even within families, may be low. Methodological problems exist in diagnosis, such as inconsistencies in results obtained from different assays used to measure fac

Assessment of diastolic function and atrial remodeling by MRI – validation and correlation with echocardiography and filling pressure

Atrial fibrosis can be estimated noninvasively by magnetic resonance imaging (MRI) using late gadolinium enhancement (LGE), but diastolic dysfunction is clinically assessed by transthoracic echocardiography (TTE), and rarely by MRI. This study aimed to evaluate well-established diastolic parameters using MRI, and validate them with TTE and left ventricular (LV) filling pressures, and to study the

Excipient and Dose per Unit Area Affect Sensitivity When Patch Testing with Gold Sodium Thiosulfate

Background Dose/area and reading paradigms for gold patch testing are controversial and not standardized worldwide. Objectives The aims of this study were to determine the optimum patch test dose of gold sodium thiosulfate (GST) in a hydrogel (HYD) and to establish GST HYD safety/efficacy and further characterize normal morphology and time course of GST reactions. Methods Twenty gold-allergic pati
