Meteorin is a chemokinetic factor in neuroblast migration and promotes stroke-induced striatal neurogenesis.

Ischemic stroke affecting the adult brain causes increased progenitor proliferation in the subventricular zone (SVZ) and generation of neuroblasts, which migrate into the damaged striatum and differentiate to mature neurons. Meteorin (METRN), a newly discovered neurotrophic factor, is highly expressed in neural progenitor cells and immature neurons during development, suggesting that it may be inv

A Mathematical Model of The Atrioventricular Node during Atrial Fibrillation

The atrioventricular (AV) node plays a crucial role during atrial fibrillation (AF). The aim of this study is to present an AV node model which can be fitted to short-term ECG recordings in order to infer certain AV node characteristics. The proposed model is characterized by: i) the arrival rate of atrial impulses; ii) two different refractory periods, corresponding to dual AV nodal paths; iii) t

Effects on cochlear frequency selectivity after hypobaric pressure exposure.

The effects of hypobaric pressure chamber exposure was measured in noise in ten patients with monaural fluctuating low-frequency hearing loss (FLFHL) such as Meniere's disease using psychophysical tuning curves (PTC), transiently evoked otoacoustic emissions (TEOAE), binaural pitch matches and speech recognition scores (SRS) in noise. In the literature, reversible hearing losses have been observed

Adventsuppropet problematiskt

"Vi har problem med Adventsuppropet och den privilegierade ställning som den kristna tron förutsätts ha i det, skriver 18 pastorer och församlingsledare."

Biologisk påväxt på putsade fasader

Vid Byggnadsmaterial LTH studerar vi biologisk påväxt på putsade fasader. Förutom mögel och bakterier som inte gör fotosyntes, så är samtliga andra organismer som växer på fasader fotosyntetiskt aktiva: alger, lavar och mossor. Vårt huvudintresse ligger i att beskriva samspelet mellan klimatet (främst temperatur och fukt) på fasaden, typ av fasad (isolering, putstjocklek, ytskikt, färgtyp etc.) oc

Den svenska konstfilmsinstitutionen

An analysis of the Swedish art cinema as an institutional practice, considered as the art film canon, the film criticism, and the field of cinema studies.

Energy resolved electron – ion coincidence study near the S 2p thresholds of the SF6 molecule

The fragmentation dynamics of the SF6 molecule following the excitations of S 2p electrons into unoccupied molecular orbitals has been studied using the energy-resolved electron–ion coincidence technique. Fragmentation patterns were found to depend on the particular excitation and on the electronic state of the molecular ion. The spectator resonant Auger decay at the 2p → 6a1g resonance induces ch

A priori modeling for gradient based inverse scattering algorithms

This paper presents a Fisher information based Bayesian approach to analysis and design of the regularization and preconditioning parameters used with gradient based inverse scattering algorithms. In particular, a one-dimensional inverse problem is considered where the permittivity and conductivity profiles are unknown and the input data consist of the scattered field over a certain bandwidth. A p

Techniques to reduce radiation for patients and operators during aortic endografting.

Endovascular aortic repair of aortic pathologies has become widely spread among vascular surgeons. Much focus has been directed at perfecting and developing endovascular procedures to treat evermore-complex issues. Much less focus has been directed at the radiation hazards to patients as well as operators and staff when such procedures are performed. Radiation exposure must be used according to th
