Landau parameters for energy density functionals generated by local finite-range pseudopotentials

In Landau theory of Fermi liquids, the particle-hole interaction near the Fermi energy in different spin-isospin channels is probed in terms of an expansion over the Legendre polynomials. This provides a useful and efficient way to constrain properties of nuclear energy density functionals in symmetric nuclear matter and finite nuclei. In this study, we present general expressions for Landau param

Protective effects of BDNF and NT-3 but not PDGF against hypoglycemic injury to cultured striatal neurons

Brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and platelet-derived growth factor (PDGF) exert trophic effects on striatal neurons in vitro, which raises the possibility that these growth factors might also counteract neuronal death provoked by various insults. We have found that BDNF and NT-3, but neither PDGF-AA nor -BB, added 24 h before the insult ameliorated hypoglycemic neu

Differential regulation of mRNAs for nerve growth factor, brain-derived neurotrophic factor, and neurotrophin 3 in the adult rat brain following cerebral ischemia and hypoglycemic coma

In situ hybridization was used to study expression of mRNAs for members of the nerve growth factor (NGF) family in the rat brain after 2 and 10 min of forebrain ischemia and 1 and 30 min of insulin-induced hypoglycemic coma. Two hours after the ischemic insults, the level of brain-derived neurotrophic factor (BDNF) mRNA was markedly increased in the granule cells of the dentate gyrus, and at 24 h

Inversion of the early component of IPSPs in neurons of the sensorimotor cortex by artificial hyperpolarization of the membrane was demonstrated in cats immobilized by myorelaxants in acute experiments. The late component of IPSP was not inverted. Amplitudes of the early component of IPSPs were decreased by the membrane depolarization while the late component was completely reduced. The input resi

European Position Statement on Diagnosis, and Treatment of Meniere's Disease

Meniere Disease keeps challenges in its diagnosis and treatment since was defined by Prosper Meniere at the beginning of 19th Century. Several classifications and definition were made until now and speculations still exist on its etiology. As the etiology remains speculative the treatment models remain in discussion also. The European Academy of Otology and Neurotology Vertigo Guidelines Study Gro

Three-dimensional microstructure of human meniscus posterior horn in health and osteoarthritis

Objective: To develop and perform ex vivo 3D imaging of meniscus posterior horn microstructure using micro-computed tomography (μCT), and to compare specimens from healthy references against end-stage osteoarthritis (OA) using conventional section-based histology and qualitative μCT. Design: We retrieved human medial and lateral menisci from 10 deceased donors without knee OA (healthy references)

RNAi as a Tool to Study Virulence in the Pathogenic Yeast Candida glabrata

The yeast Candida glabrata is a major opportunistic pathogen causing mucosal and systemic infections in humans. Systemic infections caused by this yeast have high mortality rates and are difficult to treat due to this yeast's intrinsic and frequently adapting antifungal resistance. To understand and treat C. glabrata infections, it is essential to investigate the molecular basis of C. glabrata vir

New Technique for Preconditioning of the Spinal Cord Before Endovascular Repair of Descending Thoracic and Thoracoabdominal Aortic Aneurysms

Purpose: To propose a new simplified technique to occlude multiple segmental arteries for staging and preconditioning of the spinal cord to decrease the potential for spinal cord ischemia after thoracic and thoracoabdominal aortic aneurysm repair. Technique: A thoracic stent-graft that flares out to a maximum of 51 mm is deployed in a standard fashion covering all segmental arteries where graft-wa

Nonlocal energy density functionals for pairing and beyond-mean-field calculations

We propose to use two-body regularized finite-range pseudopotential to generate nuclear energy density functional (EDF) in both particle-hole and particle-particle channels, which makes it free from self-interaction and self-pairing, and also free from singularities when used beyond mean field. We derive a sequence of pseudopotentials regularized up to next-to-leading order and next-to-next-to-lea

Sunset integrals at finite volume

Chiral Perturbation Theory is a useful tool to aid in performing the various extrapolations needed in lattice QCD calculations of physical quantities. These include extrapolations in quark mass, finite lattice spacing and finite size of the lattice. Especially the latter will becomemore important when the quark masses on the lattice become smaller. Here we develop the needed two-loop integrals at

Bacterial pseudokinase catalyzes protein polyglutamylation to inhibit the SidE-family ubiquitin ligases

Enzymes with a protein kinase fold transfer phosphate from adenosine 5'-triphosphate (ATP) to substrates in a process known as phosphorylation. Here, we show that the Legionella meta-effector SidJ adopts a protein kinase fold, yet unexpectedly catalyzes protein polyglutamylation. SidJ is activated by host-cell calmodulin to polyglutamylate the SidE family of ubiquitin (Ub) ligases. Crystal structu

Biological treatment of ankylosing spondylitis : A nationwide study of treatment trajectories on a patient level in clinical practice

Background: There is substantial evidence that patients with ankylosing spondylitis (AS) have high response rates to tumour necrosis factor inhibitors (TNFi), a low likelihood of successful treatment termination, but yet a limited drug retention. Whereas several reports have assessed drug retention rates for TNFi in AS, there are few, if any, studies investigating the actual treatment trajectories

Dialogue with property owners and property developers as a tool for sustainable transformation : A literature review

The housing sector is important for achieving ambitious environmental targets. In the European Union, buildings account for 40% of energy consumption and 36% of CO2 emissions. Considering the scale of the housing sector's environmental impact, interventions in how new housing is built and existing housing is renovated have great potential for sustainable transformation. However, the sector has not

Randomized clinical trial of open suture repair versus totally extraperitoneal repair for treatment of sportsman's hernia

Background: Sportsman's hernia/athletic pubalgia is a recognized cause of chronic groin pain in athletes. Both open and laparoscopic surgical repairs have been described for treatment, but there are no comparative studies. The hypothesis here was that relief of pain would be achieved earlier in patients treated with open minimal suture repair than totally extraperitoneal repair. Methods: A randomi
