Transmissible spongiform encephalopathies are characterised by widespread deposition of fibrillar and/or plaque-like forms of the prion protein. These aggregated forms are produced by misfolding of the normal prion protein, PrP(C), to the disease-associated form, PrP(Sc), through mechanisms that remain elusive but which require either direct or indirect interaction between PrP(C) and PrP(Sc) is...

AIM The aim of this study was to test the effect of new protocol of glide path preparation by 20/0.04 rotary file on apical extrusion of debris when instrumenting fine curved mesial canals in mandibular molars with Self-adjusting File (SAF) and compare it to a glide path prepared by 20/0.02 hand K-file and rotary OneShape (OS) and reciprocating WaveOne (WO) file instrumentation. MATERIALS AND...

Se aplicaron métodos no destructivo destructivo, para el cafeto respectivamente, método Walkley-Black orgánico suelo hojarasca m...

Soil erosion is one of the problems threatening Algerian environment. In agriculture, soil leads to thinning topsoil under effect natural erosive forces water, or agricultural activities. The present study aims estimate average loss rate and identify vulnerable zones. Through integration RUSLE model at Saf watershed, various parameters are utilized such as rainfall erosivity factor (R), erodibi...

Amaç: Bu çalışmanın amacı, kök kanallarından modifiye üçlü antibiyotik patının (mTAP) çıkarılmasında foton kaynaklı fotoakustik dalgalanma (PIPS) tekniği ile farklı irrigasyon aktivasyon rejimlerinin kombinasyonunun etkinliğini karşılaştırmaktır.
 Gereç ve Yöntemler: Yüz beş adet çekilmiş insan mandibular-premolar dişler ProTaper döner eğe kullanarak prepare edildi. Kök kanalları mTAP medi...

Synthetic antiferromagnets (SAFs) consist of two thin ferromagnetic particles separated by a thin nonmagnetic spacer. The magnetic moments of the two particles couple antiparallel via dipolar interactions, with the interlayer exchange interaction suppressed by a suitable choice of the spacer material. The SAF system studied in this thesis contains thin elliptical-in-the-plane permalloy particle...

Technical Abstract We determined orientations of principal stresses around the San Andreas Fault (SAF) system in the greater San Francisco Bay Area and regions further north along the strike-slip plate boundary. Stress orientations, as well as a ratio between stress magnitudes, were determined by inversions of approximately 6000 earthquake fault plane solutions, divided into ~100 groups based o...

MOTIVATION The distribution of allele frequencies across polymorphic sites, also known as the site frequency spectrum (SFS), is of primary interest in population genetics. It is a complete summary of sequence variation at unlinked sites and more generally, its shape reflects underlying population genetic processes. One practical challenge is that inferring the SFS from low coverage sequencing d...

OBJECTIVES Diabetes develops much more often in patients suffering from rheumatoid arthritis (RA) than in healthy population. One of the parameters which allow to evaluate the risk of developing diabetes and cardiovascular diseases (CVD) is the level of advanced glycation end products (AGE) in the skin. In patients suffering from RA, an increase in AGE level may be also linked with the course o...

BACKGROUND Chronic obstructive pulmonary disease (COPD) is a chronic lung disease characterized by chronic airway inflammation and emphysema, and is caused by exposure to noxious particles or gases, e.g. cigarette smoke. Smoking and oxidative stress lead to accelerated formation and accumulation of advanced glycation end products (AGEs), causing local tissue damage either directly or by binding...
