A Structural Classification of Candidate Oscillatory and Multistationary Biochemical Systems

Molecular systems are uncertain: The variability of reaction parameters and the presence of unknown interactions can weaken the predictive capacity of solid mathematical models. However, strong conclusions on the admissible dynamic behaviors of a model can often be achieved without detailed knowledge of its specific parameters. In systems with a sign-definite Jacobian, for instance, cycle-based cr

Structures of endothiapepsin-fragment complexes from crystallographic fragment screening using a novel, diverse and affordable 96-compound fragment library

Crystallographic screening of the binding of small organic compounds (termed fragments) to proteins is increasingly important for medicinal chemistry-oriented drug discovery. To enable such experiments in a widespread manner, an affordable 96-compound library has been assembled for fragment screening in both academia and industry. The library is selected from already existing protein-ligand struct

Graduates’ perceptions of prosthetic and orthotic education and clinical practice in Tanzania and Malawi

Background: Maintaining and improving the quality of prosthetics and orthotics education at the Tanzania Training Centre for Orthopaedic Technologists is essential for the provision of appropriate prosthetics and orthotics services in African countries.Objectives: To describe how Tanzanian and Malawian graduates’ of the Diploma in Orthopaedic Technology perceive their education and how it could be

Refill adherence in relation to substitution and the use of multiple medications : A nationwide population based study on new ACE-inhibitor users

Objective: Generic substitution has contributed to economic savings but switching products may affect patient adherence, particularly among those using multiple medications. The aim was to analyse if use of multiple medications influenced the association between switching products and refill adherence to angiotensin-converting-enzyme (ACE) inhibitors in Sweden. Study Design and Setting: New users

Health transition after lung transplantation - a grounded theory study

Aims and objectives: To investigate lung recipients' process of transition from prior the transplantation to one year afterwards, as well as what their main concerns are and how they deal with these concerns. Background: During the last three decades, lung transplantation has been established as an effective treatment for patients with end-stage pulmonary disease. Towards the end of the 20th centu

The Mullnäset rapakivi granite, its chemical and mineralogical composition including a comparison with the Sörvik granite, west central Sweden.

This contribution presents complimentary mineralogical and whole-rock chemical data for the Mullnäset rapakivi massif. Three rock types occur: gabbro, syenite with associated granite and “normal” rapakivi granite, here denoted rapakivi-textured granite. In the syenite-associated granite, extremely Mg-poor clinopyroxene and fayalite are the most important mafic minerals, whereas ferrohornblende and

The evolution of substrate specificity-associated residues and Ca2+-binding motifs in EF-hand-containing type II NAD(P)H dehydrogenases

Most eukaryotic organisms, except some animal clades, have mitochondrial alternative electron transport enzymes that allow respiration to bypass the energy coupling in oxidative phosphorylation. The energy bypass enzymes in plants include the external type II NAD(P)H dehydrogenases (DHs) of the NDB family, which are characterized by an EF-hand domain for Ca2+ binding. Here we investigate these pla

Slow-light-based optical frequency shifter

We demonstrate experimentally and theoretically a controllable way of shifting the frequency of an optical pulse by using a combination of spectral hole burning, slow light effect, and linear Stark effect in a rare-earth-ion-doped crystal. We claim that the solid angle of acceptance of a frequency shift structure can be close to 2π, which means that the frequency shifter could work not only for op

6;7 chromosomal translocation in spontaneously arising rat immunocytomas : evidence for c-myc breakpoint clustering and correlation between isotypic expression and the c-myc target

Our previous studies have shown that spontaneously arising immunocytomas in the LOU/Ws1 strain of rats contain a t(6;7) chromosomal translocation in all seven tumors studied (F. M. Babonits, J. Spira, G. Klein, and H. Bazin, Int. J. Cancer 29:431-437, 1982). We have also shown that the c-myc is located on chromosome 7 (J. Sümegi, J. Spira, H. Bazin, J. Szpirer, G. Levan, and G. Klein, Nature (Lond

Who are the world leaders in innovation? Exploring the changing role of firms in emerging economies

Recent literature shows that differences in structural characteristics at country level are important determinants of the innovative capacities and growth performance of different countries. Based on firm-level data collected from a survey, this study identifies who are the world leaders, followers, and marginalised firms in a sample of nine countries and a selection of industries in terms of firm

Pre-diagnostic meat and fibre intakes in relation to colorectal cancer survival in the European Prospective Investigation into Cancer and Nutrition

Improvements in colorectal cancer (CRC) detection and treatment have led to greater numbers of CRC survivors, for whom there is limited evidence on which to provide dietary guidelines to improve survival outcomes. Higher intake of red and processed meat and lower intake of fibre are associated with greater risk of developing CRC, but there is limited evidence regarding associations with survival a
