Soil organic carbon (SOC) plays an important role in the global C cycle, as well maintenance and improvement of soil quality. Over time, special attention has been paid to it study SOC reserves worldwide; however, reduced given assessing spatial patterns stock (SOCS) semi-desert ecosystems. In this line, there are no conclusive studies drylands Africa affected by aeolian processes (semi-desert ...

In a reconnaissance study, we investigated the potential of γ-ray induced production 38ArK from 39K for geochronological applications. For this purpose, various age monitors commonly in use established 40Ar/39Ar-method were co-irradiated 60 h at 17.6 MeV maximum energy ELBE facility, Dresden-Rossendorf, Germany. Because available was low, total depressed, leading to low J38-values (2.1–4.1) × 1...

Introduction: The age of the ~23 km in diameter Rochechouart impact structure, France, hosted by Precambrian to Paleozoic (Variscan) crystalline rocks of the northwestern French Massif Central, has long time been a matter of debate. Previous studies, including K-Ar, Rb-Sr, apatite and glass fission track, as well as paleomagnetic dating (see [1] for summary of ages), resulted in a broad (Middle...

BACKGROUND Constitutively active androgen receptor variants (AR-V) lacking the ligand binding domain (LBD) may promote the development of castration-resistant prostate cancer (CRPC). The expression of AR-Vs in the clinically most important metastatic site, the bone, has, however, not been well documented. Our aim was therefore to compare levels of AR-Vs in hormone-naive (HN) and CRPC bone metas...

The androgen receptor (AR) plays a crucial role in normal physiology, development and metabolism as well as in the aetiology and treatment of diverse pathologies such as androgen insensitivity syndromes (AIS), male infertility and prostate cancer (PCa). Here we show that dimerization of AR ligand-binding domain (LBD) is induced by receptor agonists but not by antagonists. The 2.15-Å crystal str...

To determine whether A(3) adenosine receptor (A(3)AR) signaling modulates myocardial function, energetics, and cardioprotection, hearts from wild-type and A(3)AR-overexpressor mice were subjected to 20-min ischemia and 40-min reperfusion while (31)P NMR spectra were acquired. Basal heart rate and left ventricular developed pressure (LVDP) were lower in A(3)AR-overexpressor hearts than wild-type...

Background Allergic rhinitis (AR) is a multifaceted condition affecting up to 40% of the population. AR leads to nasal symptoms of congestion, rhinorrhea, sneezing, and nasal itching. It is often associated with ocular symptoms of itching/burning, tearing/watering and redness. AR has a negative impact on patients’ quality of life (QoL) due to both nasal and ocular symptoms. Market research show...

Background Allergic rhinitis (AR) is very common in children and it affects 10–40% of children world-wide. Asthma and AR commonly coexist and we can find up to 30% of asthma in patients with AR and up to 90% of AR in patients with asthma. Moreover, these two disorders seem to influence each other’s activity and intensity. Physical activity is commonly prescribed as a rehabilitation treatment fo...

A new design method for an ultra-wideband circularly polarized microstrip-fed monopole antenna with a ground defect is proposed in this paper. To achieve circular polarization performance, parallelogram-shaped employed the bottom layer. The analysis of axial ratio (AR) and impedance bandwidth performed both top layers. semi-circular aperture designed to matching 24–40 GHz frequency range. Then,...
