Background:Still little is known about the impact on right ventricle function of the 2 main approaches to Norwood palliation in Hypoplastic left heart syndrome,the right ventricle-pulmonary artery shunt(RVPAS)and the modified Blalock-Taussig shunt(mBTS).Methods:The cohort included 27 patients with Hypoplastic left heart syndrome(10 in the mBTS group,17 in the RVPAS group).Longitudinal strain,tricuspid annulus peak systolic excursion and fractional area change were evaluated before Norwood and in four different breakpoints in the steady-state after Norwood procedure(30-days,90-days,140-days and 200-days after Norwood).Results:No significant differences were found in all standard echocardiographic functional parameters between the two groups at any ***,when we compared right ventricle function before and after Norwood procedure,longitudinal strain significantly improved in mBTS group compared to pre-surgical assessment(after 90-days:mBTS+27,35%±43,47 ***-8,20%±25,25,p=0,03;after 200-days:mBTS+10.19%±36.58 ***-21.64%±30.43,p=0.04).Conclusion:The mBTS group,which did not receive any ventriculotomy,showed a significant increase in right ventricle longitudinal strain during *** data support the use of longitudinal strain in Hypoplastic left heart syndrome evaluation and may suggest potential value in terms of cardiac mechanics in using mBTS,preserving the right ventricle integrity.

Mechanisms of electrochemical magnesium(de)alloying of Mg-Sn and Mg-Pb polymorphs

引用

Journal of Magnesium and Alloys 2022年第6期10卷 1609-1616页

作者： Clément Pechberty Antoine Klein Bernard fraisse Lorenzo Stievano Romain Berthelot ICGM CNRSUniv.MontpellierENSCMMontpellierFrance RS2E CNRSHub de l’EnergieAmiensFrance

Different polymorphs of Mg-Sn and Mg-Pb intermetallic compounds were prepared by high-energy mechanical alloying and then investigated as active material in magnesium batteries. Beside thermodynamically stable Mg_(2)Sn and Mg_(2)Pb crystallizing in the anti-fluorite structure, other polymorphs Mg_(~2)Sn and Mg_(~2)Pb were prepared by increasing the ball-milling time. The first dealloying process is almost complete only for the cubic polymorphs, then similar capacities are observed during the subsequent alloying and dealloying *** to operando X-ray diffraction, the electrochemical mechanism is revealed and shows that the cubic polymorphs Mg_(2)Sn and Mg_(2)Pb tend to preferentially form during the alloying whatever the pristine intermetallic. Weak traces of Mg_(~2)Sn and Mg_(~2)Pb are observed during the alloying, suggesting that these polymorphs act as a by-product and/or an intermediate phases of the electrochemical process. Finally, the compatibility of cubic Mg_(2)Sn and Mg_(2)Pb with Mg(TFSI)_(2)-based electrolyte is confirmed in full cell vs. a positive electrode based on the Chevrel phase Mo6S8, although limited performance is achieved. This fundamental work provides new insights in the behavior of alloy-type negative electrodes for magnesium-ion batteries.

Objective: To evaluate the total phenolic contents, antioxidant and antiglycation activities of leaves, barks, roots and kernels from two cultivars of Mangifera indica(Anacardiaceae). Methods: Total phenolic contents were determined by using Folin-Ciocalteu's method. The antioxidant activities were assessed by three different protocols including DPPH, oxygen radical absorbance capacity and iron(Ⅱ) chelation assays. In addition, in vitro bovine serum albumin/D-ribose assay was chosen to evaluate the antiglycation properties of the extracts. Results: All the investigated extracts were found to contain high level of total phenols as well as potent antioxidant activities. Kernel extracts showed the highest total phenol contents and DPPH radical scavenging activities whereas higher oxygen radical absorbance capacity values were observed for leave, root and bark extracts. Besides, extracts from leaves, roots and barks from both cultivars exhibited potent inhibitory effects against the formation of advanced glycation end products, with IC_(50) values lower than the standard positive control aminoguanidine. Conclusions: The potent antiglycation and antioxidative activities of these two Mangifera indica cultivars suggest a possible role in targeting aging, diabetic complications and oxidative stress related diseases.

Caffeoyl Derivatives: Major Antioxidant Compounds of Some Wild Herbs of the <i>Asteraceae</i>Family

引用

Food and Nutrition Sciences 2011年第3期2卷 181-192页

作者： Didier fraisse Catherine Felgines Odile Texier Jean-Louis Lamaison 不详

The polyphenolic composition and antioxidant activity of the aerial parts of 18 medicinal or food plants of the As- teraceae family were studied. Five main caffeoyl derivatives were determined individually by HPLC and compared with levels determined by colorimetry for total dihydroxycinnamic derivatives and total phenolics. The aim of this study was to assess the contribution of these constituents to the antioxidant activity of the herbs determined by DPPH radical scavenging tests. Significant correlations were found between total phenolic (R2 = 0.8904), total dihydroxycinnamic derivative (R2 = 0.8529) and total caffeoyl derivative (R2 = 0.7172) concentrations and the DPPH-scavenging ability of all herbs. The antioxidant activity of the main constituents, including chicoric acid (EC50 = 8.24 μmol/l) or 3,5- dicaffeoylquinic acid (EC50 = 7.62 μmol/l), was very high compared to vitamin C (EC50 = 15.66 μmol/l). Thus, for each species, antioxidant activity mainly involves the major caffeoyl derivatives. The contribution to antioxidant activity were assessed as 48.92% for 3,5-dicaffeoylquinic acid in Tanacetum parthenium (30.08 g/kg), and 68.96% for chicoric acid in Taraxacum officinale (34.08 g/kg). The main caffeoyl derivatives among polyphenols can be considered as the major antioxidant compounds of the studied Asteraceae herbs.

较长时期内,负离子质谱,主要是低压电子电离负离子质谱,由于负离子丰度很低,在质谱分析中实际应用较少.随着高压质谱,即化学电离质谱的发展和检测技术的改进,负离子质谱,特别是负化学电离质谱(NCI),灵敏度与正化学电离质谱(PCI)相似或更高,操作技术一般不比正化学电离质谱困难.谨慎选择电离条件,对某些化合物,NCI比PCI可获得有关分子结构更有价值的信息.NCI已成为具有广泛实际使用价值的质谱技术.

This study compares various optimization criteria for a solar domestic hot water system(SDHWS).First of all,we present the various parameters used to evaluate a SDHWS. Various optimization criteria of a standard solar hot water system are then *** optimized solutions are compared with a standard hot water *** most suitable criteria take into account both energetic and financial *** most powerful solutions tend to increase the collector area and reduce the tank volume. Some of the usual evaluation criteria for SDHWs cannot be used as optimization criteria because they do not consider the auxiliary heater,resulting in inaccurate indications of the system’s ***,it seemed important to propose a new evaluation method which integrates the financial savings(LCS),energetic savings(primary)and CO2 emission savings(environmental)with regard to a referenced solution based on a radar diagram.
