THz-PCR Based on Resonant Coupling between Middle Infrared and DNA Carbonyl Vibrations
The carbonyl groups of deoxyribonucleotide can resonantly
couple
with 53 THz middle infrared, which can highly transmit water without
ionization-based damage to DNA molecules. Herein, we predict that
vibrational coupling with THz irradiation could lower down the hybridization
landscape of nucleic acids and thus affect DNA replication. Using
polymerase chain reaction (PCR) as a measure, we found that THz shining
can reduce the denature temperature of DNA duplexes by about 3 °C,
which allows one to conduct PCR at lower temperature, facilitating
long-time amplification reaction without losing enzymatic fidelity,
i.e., normal PCR should be carried out at denaturing temperature ∼4
°C higher than the melting temperature (Tm), but THz-PCR only requires temperature ∼1 °C
higher than Tm due to the nonthermal effect
of THz shining. Moreover, the melting time can also be shortened to
1/5 due to the enhanced vibration coupling with 53 THz irradiation.
We proposed THz-PCR as an innovated DNA amplification technique with
ultrahigh specificity and sensitivity and also successfully demonstrated
its advantages in forensic detections
Pressure-Dependent Kinetics of the Reaction between CH<sub>3</sub>OO and OH Focusing on the Product Yield of Methyltrioxide (CH<sub>3</sub>OOOH)
The
reaction kinetics of methyl peroxy radical (CH3OO)
and hydroxyl radical (OH) has attracted an increasing level of interest
in the past decade, while the branching yields of various product
channels are still under debate. In this work, a comprehensive theoretical
effort was made to investigate the branching yield of the stabilized
methyltrioxide (CH3OOOH, TRIOX) adduct, which has recently
been a research focus. Our computed branching ratio of TRIOX at 298
K and 760 Torr is ∼0.04, in agreement with the result of multiplexed
photoionization mass spectrometry. We show that the large branching
yield obtained in an early theoretical study mainly originated from
the collision-induced strong stabilization presented in their simulation.
Our findings clarify the controversial product yield results for this
important species in recent studies. The computed rate constants over
wide temperature and pressure ranges allow better integration of this
reaction into global atmospheric models and low-temperature combustion
kinetic models
Effects of Olefin Group and Its Position on the Kinetics for Intramolecular H-Shift and HO<sub>2</sub> Elimination of Alkenyl Peroxy Radicals
Two classes of unimolecular reactions of peroxy radicals are key to autoignition, namely, intramolecular H-atom shift (which promotes autoignition) and concerted HO2 elimination (which inhibits autoignition). Olefin groups are prominent functional groups in biodiesel fuels. This paper explores the effects of the presence of an olefin group and its position on the kinetics of unimolecular reactions of peroxy radicals. CBS-QB3 calculations were carried out for 10 selected alkyl- and alkenylperoxy radicals. Transition-state theory was used to determine the temperature dependence of the high-pressure limiting rate constants, and Rice−Ramsperger−Kassel−Marcus/master equation simulations were performed to determine the pressure dependence of selected rate constants. Tunneling effects were computed using the asymmetric Eckart potential. The contribution of internal rotors to partition functions were included by using the hindered-rotor treatment
RT-PCR Analysis of <i>P-oo</i> Transcripts
<p>RNA was extracted from kernel pericarp (20 DAP), reverse transcribed, and PCR-amplified using primers complementary to both <i>p1</i> and <i>p2</i> transcripts. The progenitor allele <i>(P1-rr11)</i> shows amplification of a 605-bp band from <i>p1.</i> The <i>p-ww2</i> and <i>P-oo</i> alleles show amplification of a 522-bp band characteristic of the 5′ region of the <i>p2</i> gene. The <i>p1-ww1112</i> allele has a deletion of <i>p1;</i> the native <i>p2</i> gene is intact in this allele, but is not expressed in kernel pericarp.</p

Data_Sheet_2_Development and Validation of the Win-Win Scale.zip
Accumulating evidence has shown that win-win is necessary for both individuals and the society. This research, including two studies, aimed to develop and validate a measurement of the win-win scale. In the first study, we screened the items by item analysis and extracted common factors using exploratory factor analysis (EFA), thus determining a total of 25 items in the initial scale consisted of five dimensions including integrity, advancement, altruism, harmoniousness, and coordination. In the second study, we used first- and second-order confirmatory factor analysis (CFA) to test the scale’s construct validity. The results indicated a good fit between the five-factor model and the data. Based on our results, we have formed a win-win scale by keeping 16 items from the original project pool.</p
