Fixation failure with resulting non-union is the key complication after femoral neck fixation. find more It can be avoided by permitting dynamic compression and reducing rotation and posterior tilt of the femoral head. To achieve this, a novel implant that features an interlocking plate with three hook-pins (The Hansson Pinloc® System) was developed from the original two hook-pins. Only an enhanced torsional fixation by the implant modification is reported. The purpose was to compare the biomechanical compressive and bending stability of the original and modified implant in femoral neck fixation. To analyze the contribution of both modified components, three individual pins were included, although not in regular use. Forty-eight synthetic femurs with mid-cervical wedge osteotomies were fixated by two pins or identical triangular pin patterns with or without the plate. Eight specimens of each group were loaded cyclically in compression with an inferior wedge to simulate stance and anteroposterior bending with a posterior wedge to imitate sitting down. The clinically relevant stability measurements were stiffness and deformation. Fissure formation defined failure. The novel implant improved bending stability by 30% increased stiffness, 44% reduced deformation, and less frequent posterior neck fissure formation (p  less then  0.001) while increased compressive stability was only evident with 25% reduced deformation and less frequent inferior neck fissures (p  less then  0.001). These impacts were mainly mediated by the third pin, while the plate prevented a lateral fissure in compression (p  less then  0.001). The clinical stability was improved by dynamic compression and decreased posterior tilt by implant modification.Until now, renin-angiotensin system (RAS) hyperactivity was largely thought to result from angiotensin II (Ang II)-dependent stimulation of the Ang II type 1 receptor (AT1R). Here we assessed the role of soluble (pro)renin receptor (sPRR), a product of site-1 protease-mediated cleavage of (pro)renin receptor (PRR), as a possible ligand of the AT1R in mediating (i) endothelial cell dysfunction in vitro and (ii) arterial dysfunction in mice with diet-induced obesity. Primary human umbilical vein endothelial cells (HUVECs) treated with a recombinant histidine-tagged sPRR (sPRR-His) exhibited IκBα degradation concurrent with NF-κB p65 activation. These responses were secondary to sPRR-His evoked elevations in Nox4-derived H2O2 production that resulted in inflammation, apoptosis and reduced NO production. Each of these sPRR-His-evoked responses was attenuated by AT1R inhibition using Losartan (Los) but not ACE inhibition using captopril (Cap). Further mechanistic exploration revealed that sPRR-His activated AT1R downstream Gq signaling pathway. Immunoprecipitation coupled with autoradiography experiments and radioactive ligand competitive binding assays indicate sPRR directly interacts with AT1R via Lysine199 and Asparagine295. Important translational relevance was provided by findings from obese C57/BL6 mice that sPRR-His evoked endothelial dysfunction was sensitive to Los. Besides, sPRR-His elevated blood pressure in obese C57/BL6 mice, an effect that was reversed by concurrent treatment with Los but not Cap. Collectively, we provide solid evidence that the AT1R mediates the functions of sPRR during obesity-related hypertension. Inhibiting sPRR signaling should be considered further as a potential therapeutic intervention in the treatment and prevention of cardiovascular disorders involving elevated blood pressure.The occurrence of foams at oceans' surfaces is patchy and generally short-lived, but a detailed understanding of bacterial communities inhabiting sea foams is lacking. Here, we investigated how marine foams differ from the sea-surface microlayer (SML), a less then 1-mm-thick layer at the air-sea interface, and underlying water from 1 m depth. Samples of sea foams, SML and underlying water collected from the North Sea and Timor Sea indicated that foams were often characterized by a high abundance of small eukaryotic phototrophic and prokaryotic cells as well as a high concentration of surface-active substances (SAS). Amplicon sequencing of 16S rRNA (gene) revealed distinctive foam bacterial communities compared with SML and underlying water, with high abundance of Gammaproteobacteria. Typical SML dwellers such as Pseudoalteromonas and Vibrio were highly abundant, active foam inhabitants and thus might enhance foam formation and stability by producing SAS. Despite a clear difference in the overall bacterial community composition between foam and SML, the presence of SML bacteria in foams supports the previous assumption that foam is strongly influenced by the SML. We conclude that active and abundant bacteria from interfacial habitats potentially contribute to foam formation and stability, carbon cycling and air-sea exchange processes in the ocean.The annual percentage improvement in standardised mortality rates in the period 2011-19 was the lowest for 70 years, whereas the 2001-10 value was the highest since records began in 1841. A similar slowdown occurred from around 2011 in most European Union countries, although this was generally less severe than in Britain. Life expectancy at birth actually fell in USA for three successive years in period 2014-17. The downturn in Britain since 2011 was wide-ranging, affecting young and old, women and men and the more and the less advantaged to a broadly similar extent. Year-to-year variation in mortality increased mainly due to increased volatility in winter excess mortality from 2011, but all seasons showed lower rates of improvement in underlying longer-term trends. Mortality had started to improve at the end of the decade and the 2019 value was the lowest-ever value in Britain. Two main explanations for these trends have been advanced UK Government post-2008 austerity policies, especially in the health and social care sectors, and the role of seasonal influenza. However, the evidence for a dominant role for either of these is weak. Longer-term overall trends have been determined principally by trends in cardiovascular rather than non-cardiovascular causes of death, although recent changes in discovery and coding of dementias makes it difficult to draw firm conclusions. Healthy life expectancy trends are also affected by changes in data and methods, but the proportion of life spent in good health for both women and men over age 65 has increased slightly since 2010.
