AIMS: Failure of healing is a well-known problem after repair of the rotator cuff. This study aimed to investigate if early repair of trauma-related full-thickness rotator cuff tears (FTRCTs) could prevent this failure. PATIENTS AND METHODS: In this prospective trial, 62 consecutive patients (14 women (23%), 48 men (77%); median age 61 years (interquartile range (IQR) 54 to 65)) with trauma-relate

Different approaches to the theoretical study of the local centres in solids are discussed. Particular attention is paid to the embedded-cluster models. There are given the mathematical formulation, the computational scheme and applications for some local centres on/in graphite monolayers of the moderately large embedded cluster and the large-unit-cell-embedded-cluster (LUC-EC) models. It is shown

Objective Blood type A antigen on porcine aortic bioprostheses might initiate an immune reaction leading to an increased frequency of structural valve deterioration in patients with blood type B or O. The aim was to analyse the association between ABO blood type and porcine bioprosthetic aortic valve degeneration. Design Observational nationwide cohort study. Setting Swedish population-based study

Performing PET imaging during ongoing radionuclide therapy can be a promising method to follow tumor response in vivo. However, the high therapeutic activity can interfere with the PET camera performance and degrade both image quality and quantitative capabilities. As a solution, low-energy photon emissions from the therapeutic radionuclide can be highly attenuated, still allowing sufficient detec

National virtual multidisciplinary team meetings have been established in Swedish cancer care in response to centralized treatment of rare cancers. Though national meetings grant access to a large multidisciplinary network, we hypothesized that video-based meetings may challenge participants’ contributions to the case discussions. We investigated participants’ views and used observational tools to

This volume is a collection of articles dealing with a question of Jewish involvement in the interfaith and intercultural dialogue in the postwar Europe, Israel and the United States. Jewish relation to alterity is seen from a few different methodological standpoints: historical, sociological, theological and literary.

We construct a model based on the electroweak gauge group SU(2)L×SU(2)R×U(1)B-L augmented by an S3 symmetry. We assign nontrivial S3 transformation properties to the quarks, and consequently we need two scalar bidoublets. Despite the extra bidoublet, we have only six Yukawa couplings thanks to the discrete symmetry. Diagonalization of the quark mass matrices shows that at the leading order only th

In a truly model-independent approach, we reexamine a minimal extension of the Standard Model (SM) through the introduction of an additional U(1) symmetry leading to a new neutral gauge boson (Z′), allowing its kinetic mixing with the hypercharge gauge boson. An SM neutral scalar is used to spontaneously break this extra symmetry, leading to the mass of the Z′. Except for three right-handed neutri

We propose an alternative method of constructing two Higgs-doublet models free from scalar mediated FCNC couplings at the tree-level. In a toy scenario, we have presented semi realistic textures for the Yukawa matrices, which can reproduce the approximate flavor structure in the quark sector. Presence of flavor diagonal but nonuniversal Yukawa couplings emerges as a distinguishing feature of such

Two-Higgs-doublet models (2HDMs) are minimal extensions of the Standard Model (SM) that may still be discovered at the LHC. The quartic couplings of their potentials can be determined from the measurement of the masses and branching ratios of their extended scalar sectors. We show that the evolution of these couplings through renormalization group equations can determine whether the observed 2HDM

Contrary to common perception, we show that the current Higgs data does not eliminate the possibility of a sequential fourth generation that get their masses through the same Higgs mechanism as the first three generations. The inability to fix the sign of the bottom-quark Yukawa coupling from the available data plays a crucial role in accommodating a chiral fourth generation which is consistent wi
