Improvement of nutritional and organoleptic quality of fruits is a key goal in current strawberry breeding *** ratio of sugars to acids is a determinant factor contributing to fruit liking,although different sugars and acids contribute in varying degrees to this complex trait.A segregating F1 population of 95 individuals,previously characterized for several fruit quality characters,was used to map during 2 years quantitative trait loci(QTL)for 50 primary metabolites,L-ascorbic acid(L-AA)and other related traits such as soluble solid content(SSC),titratable acidity(TA),and pH.A total of 133 mQTL were detected above the established thresholds for 44 *** 12.9%of QTL were detected in the 2 years,suggesting a large environmental influence on primary metabolite *** objective of this study was the identification of key metabolites that were associated to the overall variation in SSC and *** it was observed in previous studies,a number of QTL controlling several metabolites and traits were co-located in homoeology group V(HG V).mQTL controlling a large variance in raffinose,sucrose,succinic acid,and L-AA were detected in approximate the same chromosomal regions of different homoeologous linkage groups belonging to HG *** genes for selected mQTL are proposed based on their co-localization,on the predicted function,and their differential gene expression among contrasting F1 progeny ***-seq analysis from progeny lines contrasting in L-AA content detected 826 differentially expressed genes and identified Mannose-6-phosphate isomerase,FaM6PI1,as a candidate gene contributing to natural variation in ascorbic acid in strawberry fruit.

Lung transplantation (LT)has emerged as a crucial life-saving option for critically ill patients with severe coronavirus disease 2019 (COVID-19)-related acute respiratory distress syndrome (ARDS) or irreversible lung injury.[1]Intensive care unit-acquired weakness (ICU-AW)is a prevalent complication in critically ill patients.[2] The recovery of recipients undergoing LT for COVID-19-related respiratory failure may face impediments due to ICU-AW,which negatively affects early mobilization and functional improvement. This study describes two cases of successful bilateral LT for severe COVID-19-related ARDS with the occurrence of ICU-AW and subsequent successful discharge.

The effect of temperature on load partitioning evolution in magnesium metal matrix composite reinforced with Ti particles using in-situ synchrotron radiation diffraction experiments

引用

journal of Magnesium and Alloys 2023年第2期11卷 706-719页

作者： G.Garces j.medina P.Perez A.Stark N.Schell P.Adeva Department of Physical Metallurgy CSICAvenida Gregorio del Amo 8Madrid E-28040Spain Institute of Materials Physics Helmholtz-Zentrum HereonMax-Planck-Str.1Geesthacht 21502Germany

The load partitioning between the magnesium and titanium phases in an extruded Mg-15%Ti(vol.%) composite from room temperature up to 300 ℃ using synchrotron radiation diffraction during in-situ compression tests. During compression, the magnesium matrix composite deforms mainly by the activation of the extension twinning system up to 200 ℃. The volume fraction of twins increases with the plastic strain but decrease with the compression temperature. Hard titanium particles bear an additional load transferred by the soft magnesium matrix from room temperature up to 300 ℃. This effect is amplified after yield stress during plastic deformation. Additionally, twins within magnesium grains behaves as an additional reinforcement at low temperature(below 200 ℃) inducing an increase in the work hardening of the composite.
