<p>Data are presented as boxplots. Serum Ca levels of the 2<sup>nd</sup> and the 3<sup>rd</sup> trimester were significantly lower than the 1<sup>st</sup> trimester (pā=ā0.000), and with no changes during the latter two trimesters (pā=ā0.334) (A). No significant changes were observed in levels of PHOS2 (pā=ā0.288) (B) and PTH (p>0.279) (C) during pregnancy.

Three-Dimensional Conductive Gel Network as an Effective Binder for High-Performance Si Electrodes in Lithium-Ion Batteries
Silicon
(Si) has been widely investigated as a candidate for lithium-ion
batteries (LIBs) due to its extremely high specific capacity. The
binders play a key role in fabricating high-performance Si electrodes
which usually suffer from the huge volume expansion associated with
the alloying and dealloying processes. Here we develop a facile route
to prepare a three-dimensional (3D) conductive interpenetrated gel
network as a novel binder for high-performance Si anodes through chemically
cross-linking of acrylic acid monomer followed by the in situ polymerization
of aniline. The excellent electrical conductivity, strong mechanical
adhesion and high electrolyte uptake render the conductive gel network
a potential binder for high-performance Si anodes. The resultant Si
anodes exhibit excellent cycling stability, high Coulombic efficiency
and superior rate capability, revealing better electrochemical properties
compared to the Si anodes with conventional binders. The 3D conductive
gel binder could not only accommodate the volume expansion and maintain
electric connectivity, but also assist in the formation of stable
solid electrolyte interphase (SEI) films. Such a strategy sheds light
on the design of polymer binders in LIBs, especially for high-capacity
electrode materials with huge volume changes during long-term cycling

Synthesis, Hardness, and Electronic Properties of Stoichiometric VN and CrN
We
report synthesis of single-crystal VN and CrN through high-pressure
ion-exchange reaction routes. The final products are stoichiometric
and have crystallite sizes in the range of 50ā120 Ī¼m.
We also prepared VN and TiN crystals using high-pressure sintering
of nitride powders. On the basis of single-crystal indentation testing,
the determined asymptotic Vickers hardness for TiN, VN, and CrN is
18 (1), 10 (1), and 16 (1) GPa, respectively. The relatively low hardness
in VN indicates that the metallic bonding prevails due to the overfilled
metallic Ļ bonds, although the cationāanion covalent
hybridization in this compound is much stronger than that in TiN and
CrN. All three nitrides are intrinsically excellent metals at ambient
pressure. In particular, VN exhibits superconducting transition at <i>T</i><sub>c</sub> ā 7.8 K, which is slightly lower than
the reported values for nitrogen-deficient or crystalline-disordered
samples due to unsuppressed āspin fluctuationā in the
well-crystallized stoichiometric VN. The magnetostructural transition
in CrN correlates with a metalāmetal transition at T<sub>N</sub> = 240Ā(5) K and is accompanied
by a ā¼40% drop in electrical resistivity. In addition, more
detailed electronic properties are presented with new insights into
these nitrides

Image_2_Suppression of SlMBP15 Inhibits Plant Vegetative Growth and Delays Fruit Ripening in Tomato.TIF
<p>MADS-box genes have been demonstrated to participate in a number of processes in tomato development, especially fruit ripening. In this study, we reported a novel MADS-box gene, SlMBP15, which is implicated in fruit ripening. Based on statistical analysis, the ripening time of SlMBP15-silenced tomato was delayed by 2ā4 days compared with that of the wild-type (WT). The accumulation of carotenoids and biosynthesis of ethylene in fruits were decreased in SlMBP15-silenced tomato. Genes related to carotenoid and ethylene biosynthesis were greatly repressed. SlMBP15 can interact with RIN, a MADS-box regulator affecting the carotenoid accumulation and ethylene biosynthesis in tomato. In addition, SlMBP15-silenced tomato produced dark green leaves, and its plant height was reduced. The gibberellin (GA) content of transgenic plants was lower than that of the WT and GA biosynthesis genes were repressed. These results demonstrated that SlMBP15 not only positively regulated tomato fruit ripening but also affected the morphogenesis of the vegetative organs.</p
