Microwave Spectrum and Molecular Structure of Vinyl Chloride–Acetylene, A Side Binding Complex
The
structure of the gas-phase bimolecular complex formed between
vinyl chloride and acetylene is determined using a combination of
broad-band, chirped-pulse, and narrow-band, Balle–Flygare Fourier
transform microwave spectroscopy from 5.8 to 20.7 GHz. Although all
previous examples of complexes formed between protic acids and haloethylenes
are observed to have similar modes of binding regardless of the specific
identity of the acid, HF, HCl, or HCCH, the vinyl chloride–HCCH
complex has HCCH located at one end of the vinyl chloride with the
secondary interaction occurring with the geminal hydrogen atom as
opposed to the “top” binding configuration found for
vinyl chloride–HF. Nevertheless, the details of the structure,
such as hydrogen bond length (3.01 Ă…) and amount of deviation
from linearity (58.5°), do reflect the strength of the interaction
and show clear correlations with the gas-phase acidity. Comparison
with analogous complexes allows the determination of the relative
importance of electrostatic interactions and steric requirements in
leading to the observed structures
Presentation_1_Nitric Oxide Affects Rice Root Growth by Regulating Auxin Transport Under Nitrate Supply.pdf
<p>Nitrogen (N) is a major essential nutrient for plant growth, and rice is an important food crop globally. Although ammonium (NH<sub>4</sub><sup>+</sup>) is the main N source for rice, nitrate (NO<sub>3</sub><sup>-</sup>) is also absorbed and utilized. Rice responds to NO<sub>3</sub><sup>-</sup> supply by changing root morphology. However, the mechanisms of rice root growth and formation under NO<sub>3</sub><sup>-</sup> supply are unclear. Nitric oxide (NO) and auxin are important regulators of root growth and development under NO<sub>3</sub><sup>-</sup> supply. How the interactions between NO and auxin in regulating root growth in response to NO<sub>3</sub><sup>-</sup> are unknown. In this study, the levels of indole-3-acetic acid (IAA) and NO in roots, and the responses of lateral roots (LRs) and seminal roots (SRs) to NH<sub>4</sub><sup>+</sup> and NO<sub>3</sub><sup>-</sup>, were investigated using wild-type (WT) rice, as well as osnia2 and ospin1b mutants. NO<sub>3</sub><sup>-</sup> supply promoted LR formation and SR elongation. The effects of NO donor and NO inhibitor/scavenger supply on NO levels and the root morphology of WT and nia2 mutants under NH<sub>4</sub><sup>+</sup> or NO<sub>3</sub><sup>-</sup> suggest that NO<sub>3</sub><sup>-</sup>-induced NO is generated by the nitrate reductase (NR) pathway rather than the NO synthase (NOS)-like pathway. IAA levels, [<sup>3</sup>H] IAA transport, and PIN gene expression in roots were enhanced under NO<sub>3</sub><sup>-</sup> relative to NH<sub>4</sub><sup>+</sup> supply. These results suggest that NO<sub>3</sub><sup>-</sup> regulates auxin transport in roots. Application of SNP under NH<sub>4</sub><sup>+</sup> supply, or of cPTIO under NO<sub>3</sub><sup>-</sup> supply, resulted in auxin levels in roots similar to those under NO<sub>3</sub><sup>-</sup> and NH<sub>4</sub><sup>+</sup> supply, respectively. Compared to WT, the roots of the ospin1b mutant had lower auxin levels, fewer LRs, and shorter SRs. Thus, NO affects root growth by regulating auxin transport in response to NO<sub>3</sub><sup>-</sup>. Overall, our findings suggest that NO<sub>3</sub><sup>-</sup> influences LR formation and SR elongation by regulating auxin transport via a mechanism involving NO.</p
Composite Warp-Knitted Textile with Wet–Thermal Comfort, Support, and Antimicrobial Activity for Personal Long-Term Healthcare
Moisture management materials, which can remove liquid
unidirectionally,
have excellent potential for long-term healthcare of bedridden patients
because they can handle large amounts of body fluids caused by incontinence,
sweating, etc. However, their lack of support, thermal management,
and antibacterial properties limits their clinical application. Here,
a three-dimensional thermoplastic polyurethane/warp-knitted spacer
fabric/viscose fabric (TWVF) was designed and prepared by coating
and needle-punching. TWVF had asymmetrical wettability and interpenetrating
fiber pin arrays, which could quickly and unidirectionally drain body
fluid away from the skin to keep the skin dry and clean. Meanwhile,
the low thermal conductivity of TWVF prevented excessive cooling caused
by heat loss of liquid transfer (body temperature was 4.7 °C
higher than that with cotton textiles). TWVF exhibited excellent permeability,
a low compression modulus (0.03 MPa), and a high compression strength
(0.15 MPa), providing sufficient air exchange and suitable support
for the body and reducing the risk of pressure injury. Moreover, the
incorporated aloin endowed TWVF with excellent antibacterial rates
against Staphylococcus aureus (99.61%) and Escherichia coli (98.16%), respectively. This multifunctional
textile is simple to prepare and easy to industrialize, providing
a reference for the development of functional healthcare materials

FBI-1 Enhances ETS-1 Signaling Activity and Promotes Proliferation of Human Colorectal Carcinoma Cells
<div><p>In this study, we investigated a potential regulatory role of FBI-1 in transcription factor activity of ETS-1. The protein interaction was identified between ETS-1 and FBI-1 in lovo cells. The accumulating data showed that FBI-1 promoted the recruitment of ETS-1 to endogenous promoter of its target genes and increase ETS-1 accumulation in the nuclear. Our work also indicated that the FBI-1 enhances ETS-1 transcription factor activity via down-regulating p53-mediated inhibition on ETS-1. Further, FBI-1 plays a role in regulation of colorectal carcinoma cells proliferation. These findings supported that FBI-1 might be a potential molecule target for treating colorectal carcinoma.</p></div
FBI-1 would potentially interact with ETS-1 and P53 in vivo.
<p>(A) Interaction of FLAG-FBI-1 with exogenous ETS-1 or p53 in vivo. Lovo cells were transfected with FLAG-tagged FBI-1 or FLAG empty vector. Then, cell lysates were immunoprecipitated (IP) by anti-FLAG beads, and the precipitates were then immunoblotted (IB) with anti-FLAG antibody, anti-ETS-1 antibody, or anti-p53 antibody. (B) Lovo cells were transfected with FLAG-ETS-1 vector or FLAG empty vector. The IP analysis was performed with anti-FLAG antibody, and the IB analysis was performed with anti-FLAG antibody, anti-FBI-1 antibody, or anti-P53 antibody.</p
FBI-1 can enhance the recruitment of ETS-1 to the MMP1 promoter.
<p>(A) Lovo cells stably transfected with FBI-1 or empty vector were prepared and subjected to ChIP by using IgG antibody (negative control) or antibodies for ETS-1, FBI-1 and p53. The Immunoprecipitated DNA fragment was quantified by real-time PCR assay. (B) Lovo cells, which were stably transfected with FBI-1 siRNA, or control siRNA, were harvested for the ChIP assays. The ChIP assays were performed with IgG antibody (negative control) or antibodies for ETS-1, FBI-1 and p53. *P<0.05 versus the empty vector or the FBI-1 vector (A); or versus the control siRNA or the FBI-1 siRNA (B). The cloned promoter region of MMP1 is showed above the figure.</p
