Do computational models contribute to progress in mechanobiology? Jacobs and Kelly (in Advances on Modelling in Tissue Engineering, p. 1–14, 2011) suggest that they do, but at the same time propose a limitation in the form of the ‘paradox of validation’, whereby the information needed to validate mechanoregulation theories obviates the need for them in the first place. In this article, the corrobo
The balance of intestinal microbiota, which is present in health, can be affected by severe illness and antibiotics. Pathogenic bacteria, which are usually suppressed by the commensal flora, may multiply and can cause complicating secondary infections. Administration of probiotics can help to reduce the deleterious effects of disease and antibiotics in critically ill patients: they can improve gut
A novel inhibitor of zipper-interacting protein kinase (ZIPK) was utilized to examine the involvement of ZIPK in the regulation of smooth muscle contraction. Pre-treatment of de-endothelialized rat caudal arterial smooth muscle strips with the pyrazolo[3,4-d]pyrimidinone inhibitor HS38 decreased the velocity of contraction (time to reach half-maximal force) induced by the phosphatase inhibitor cal
We present a new algorithm for solving the LPN problem. The algorithm has a similar form as some previous methods, but includes a new key step that makes use of approximations of random words to a nearest codeword in a linear code. It outperforms previous methods for many parameter choices. In particular, we can now solve instances suggested for 80-bit security in cryptographic schemes like HB var
The droplet aerosol analyzer (DAA) was developed to study the influence of aerosol properties on clouds. It measures the ambient particle size of individual droplets and interstitial particles, the size of the dry (residual) particles after the evaporation of water vapor and the number concentration of the dry (residual) particles. A method was developed for the evaluation of DAA data to obtain th
We compare the aqueous self-assembly behavior within the homologous peptide series A(n)K, where A is alanine, K is lysine, and n = 4, 6, 8, and 10. The aqueous peptide solubility, phi(s) (volume fraction), depends strongly on the number of hydrophobic alanine residues and decreases approximately as phi(s) approximate to 10(-n). Also the self-assembly structure depends on n. A(4)K is highly water-s
The use of permanent hair dyes exposes hairdressers to contact allergens such as p-phenylenediamine (PPD), and the preventive measures are insufficient.
The effectiveness of psychosocial interventions in community mental healthcare has been shown to depend on the setting in which they are implemented. Recently structured patient-clinician communication was found to be effective in a multi-centre trial in six European countries, the DIALOG trial. In the overall study, differences between centres were controlled for, not studied. Here, we test wheth
Abstract in UndeterminedA longitudinal, micro-level study of the effect of socioeconomic transformations on fertility mechanisms in the rural hinterland of Bologna between 1818 and 1900 (the beginning of the demographic transition) demonstrates that the premature death of a last-born child reduces the interval between two consecutive childbirths. Thus does it confirm the importance of breast-feedi
Objectives: To study the clinical characteristics and epidemiology of the combination of primary systemic vasculitis (PSV) and severe alpha-1 antitrypsin (α1-AT) deficiency. Method: Patients with PSV [granulomatosis with polyangiitis (GPA) (Wegener's), microscopic polyangiitis, eosinophilic granulomatosis with polyangiitis (EGPA) (Churg-Strauss), and polyarteritis nodosa] were identified through d
Purpose. The pathogenesis of rhegmatogenous retinal detachment (RRD) remains incompletely understood, with no clinically effective treatment for potentially severe complications such as photoreceptor cell death and proliferative vitreoretinopathy. Here we investigate the protein profile of the vitreous following experimental retinal detachment using a comparative proteomic based approach. Material
We propose to combine the method of fluorescence intensity centroid localization with rotation of the plane of excitation polarization. Polarized light interacts selectively with differently oriented fluorophores; thus yielding topological information on the nanometer scale, without any need for fluorophore blinking. The method is applicable to photostable individual systems, when most of the trad
We report a study on the spatial homogeneity and nitridation of a nanopattern template using a spectroscopic photoemission and low energy electron microscopy. The template was composed of Al nanodots which were patterned into a SiO2/Si(1 1 1) surface using e-beam lithography and reactive ion etching. The template exhibited a global inhomogeneity in terms of the local topography, Al composition and
The study investigates teratogenic risks with ondansetron (Zofran(®)). Data from the Swedish Medical Birth Register combined with the Swedish Register of Prescribed Drugs were used to identify 1349 infants born of women who had taken ondansetron in early pregnancy, 1998-2012. Presence of congenital malformations in the offspring was identified with three national health registers. In a Mantel-Haen
Sharp resolvent bounds for nonselfadjoint semiclassical elliptic quadratic differential operators are established, in the interior of the range of the associated quadratic symbol.
Streptococcus pneumoniae infections remain a major cause of morbidity and mortality worldwide. Therefore a detailed understanding and characterization of the mechanism of host cell colonization and dissemination is critical in order to gain control over this versatile pathogen. Here we identified a novel 72 kDa pneumococcal protein endopeptidase O (PepO), as a plasminogen and fibronectin binding p
Aims Triple-negative breast cancer (TNBC) is responsible for a disproportionate number of breast cancer (BC) deaths, owing to its intrinsic aggressiveness and a lack of treatment options, especially targeted therapies. Thus, there is an urgent need for the development of better targeted treatments for TNBC. Molecular alteration of AKT-3 was previously reported in oestrogen receptor (ER)-positive B
