Volumetric analysis of effectiveness of embolization for preventing type II endoleaks following endovascular aortic aneurysm repair.

Objective: The presence of endoleak was associated with the failure of endovascular aortic aneurysm repair (EVAR) treatment. The key to eliminating type II endoleak has shifted from reintervention to prevention. This study aimed to evaluate the effectiveness and safety of applying fibrin sealant to prevent type II endoleak in conjunction with EVAR.

Complete Endovascular Repair for Abdominal Aortic Aneurysm With Concomitant Aorto-Left Retroaortic Renal Vein Fistula.

Background: Abdominal aortic aneurysm (AAA) with concomitant aorto-retroarotic left renal vein fistula (ALRVF) is an extremely rare clinical condition. With the recent development of endovascular techniques, repair of such conditions with a complete minimal invasive approach is now possible. We reported here a case of endovascular repair of AAA with concomitant ALRVF.

Cyclic tensile strain facilitates proliferation and migration of human aortic smooth muscle cells and reduces their apoptosis via miRNA-187-3p.

The cardiovascular is a system that contains extremely complex mechanical factors, in which the circulatory flow of blood has rich mechanical laws. Many studies have revealed that mechanical factors play a very important role in the process of revascularization. Hence, it is essential to investigate the mechanical factors in the process of revascularization in depth.

Out of Southern East Asia of the Brown Rat Revealed by Large-Scale Genome Sequencing.

The geographic origin and migration of the brown rat (Rattus norvegicus) remain subjects of considerable debate. In this study, we sequenced whole genomes of 110 wild brown rats with a diverse world-wide representation. We reveal that brown rats migrated out of southern East Asia, rather than northern Asia as formerly suggested, into the Middle East and then to Europe and Africa, thousands of years ago.

[Clinical treatment of application of deep venous thrombosis by retrievable vena cava filter].

Objective: To summarize the clinical experiences of treating deep venous thrombosis (DVT) with retrievable vena cava filter.

Methods: A total of 180 patients with DVT in unilateral lower extremity were recruited. There were 82 males and 98 females with an average age of 46 years old.

[Distribution of nitrogen and hydrogen in diamond and its significance to nucleation and growth of diamond].

From the center to the rim of natural diamond there are differences in nitrogen and C-H bond contents, suggesting that diamond was formed under varying substance conditions. Both the nitrogen and C-H bond contents tend to decrease from the center to the rim as a whole, indicaing that nitrogen and hydrogen are expended little by little during the formation of diamond. But in the middle area of the sample both the nitrogen and C-H bond contents have a tendency to increase.

Structures of the four subfamilies of phosphodiesterase-4 provide insight into the selectivity of their inhibitors.

PDE4 (phosphodiesterase-4)-selective inhibitors have attracted much attention as potential therapeutics for the treatment of both depression and major inflammatory diseases, but their practical application has been compromised by side effects. A possible cause for the side effects is that current PDE4-selective inhibitors similarly inhibit isoforms from all four PDE4 subfamilies. The development of PDE4 subfamily-selective inhibitors has been hampered by a lack of structural information.

Kinetic research on the sorption of aqueous lead by synthetic carbonate hydroxyapatite.

The sorption of aqueous lead on carbonate-hydroxyapatite (CHAp) is a complicated non-homogeneous solid/water reaction, which from the kinetic point of view has two stages. In the first stage, the reaction rate is so fast and the kinetic pathway so intricate that further research is required. In the second stage, the reaction rate slows down and the reaction process follows that of a first-order kinetic equation.

[Spectroscopic studies on transition metal ions in colored diamonds].

Transition metals like nickel, cobalt and iron have been often used as solvent catalysts in high pressure high temperature (HPHT) synthesis of diamond, and nickel and cobalt ions have been found in diamond lattice. Available studies indicated that nickel and cobalt ions could enter the lattice as interstitial or substitutional impurities and form complexes with nitrogen. Polarized microscopy, SEM-EDS, EPR, PL and FTIR have been used in this study to investigate six fancy color natural and synthetic diamonds in order to determine the spectroscopic characteristics and the existing forms of transition metal ions in colored diamond lattice.

[Na and Mg K-edge XANES study in silicate glasses].

The structural role of Na in Na2-O-SiO2 and Na2O-SiO2-P2O5 glasses was studied using Na K-edge XANES (X-ray near edge structure) spectra. The Na K-edge XANES shows little change with increase in the content of Na2O in Na2O-SiO2 glasses. However, the addition of P into the Na2O-SiO2 system causes dramatic change of the Na K-edge XANES, and the Na K-edge spectra of Na2O-SiO2-P2O5 glasses also change with the increase of P2O5 content.
