Appraisal of msepCSp14 for chemosensory functions in mythimna separata

Chemosensory proteins (CSps) have great contributions in performing diverse functions in insects. However, physiological appraisal of chemosensory protein genes still remains elusive in insects. We studied expression patterns and binding affinities of msepCSp14, a chemosensory protein, in mythimna separata. The distinct functions of msepCSp14 were validated by employing different molecular techniques. The msepCSp14 had high resemblance of sequence with chemosensory proteins of other insect family members. The msepCSp14 expression was higher in antennal tissues of females than other tissues. Fluorescence binding assay validated that binding of nine out of 21 ligands to msepCSp14 was higher at pH 7.4 than at pH 5.0. Three dimensional modeling (3D) and docking analysis predicted that amino acid residues of msepCSp14 were involved in binding of compounds, and behavior assay displayed that adults of m. separata considerably responded to four volatiles from compounds demonstrating strong binding ability to msepCSp14. Results of the present study suggest that msepCSp14 is likely to mediate chemosensory functions in m. separata.

Recurrent Coronary Artery Thrombosis on Triple Anti-Thrombotic Therapy, Is There a possible Association with ChAdOx1 nCoV-19 Vaccination?

引用

Case Reports in Clinical medicine 2022年第6期11卷 234-243页

作者： phillip Crane Voltaire Nadurata m. Asrar ul Haq Department of Cardiology The Northern Hospital Epping Australia Department of Cardiology Bendigo Health Bendigo Australia

Background: Vaccines remain the only viable and safe option to control transmission and minimise disease sequelae during the COVID-19 pandemic. Whilst multiple vaccines are available, evidence has emerged regarding the association between the ChAdOx1 nCoV-19 vaccine, platelets and thrombosis, manifesting in thrombotic thrombocytopaenia. Case Summary: We report a case of recurrent coronary artery thrombosis on triple antithrombotic therapy, namely aspirin, clopidogrel, and continuous intravenous heparin, nine days after the ChAdOx1 nCoV-19 vaccine, in a 63-year-old female with no significant history of cardiovascular disease. Conclusion: This case may suggest that the association between platelets, SARS-CoV-2, the ChAdOx1 nCoV-19 vaccine, and coronary thrombosis may remain incompletely understood and warrants further study. Clinicians should remain on high alert if presented with similar circumstances.

Evolution of plasma parameters in an Ar-N2/He inductive plasma source with magnetic pole enhancement

plasma Science and Technology 2017年第2期19卷 34-42页

magnetic pole enhanced inductively coupled plasmas （mapE-ICps） are a promising source for plasma-based etching and have a wide range of material processing applications. In the present study Langmuir probe and optical emission spectroscopy were used to monitor the evolution of plasma parameters in a mapE-ICp Ar-Na/He mixture plasma. Electron density （ne） and temperature （Te）, excitation temperature （Texc）, plasma potential （Vp）, skin depth （6） and the evolution of the electron energy probability function （EEpF） are reported as a function of radiofrequency （RF） power, pressure and argon concentration in the mixture. It is observed that ne increases while Te decreases with increase in RF power and argon concentration in the mixture. The emission intensity of the argon line at 750.4 nm is also used to monitor the variation of the ‘high-energy tail＇ of the EEpF with RF power and gas pressure. The EEpF has a ‘bi-maxwellian＇ distribution at low RF powers and higher pressure in a pure N2 discharge. However, it evolves into a ‘maxwellian＇ distribution at RF powers greater than 70 W for pure N2, and at 50 W for higher argon concentrations in the mixture. The effect of argon concentration on the temperatures of two electron groups in the ‘bi-maxwellian＇ EEpF is examined. The temperature of the low-energy electron group TL shows a decreasing trend with argon addition until the ‘thermalization＇ of the two temperatures occurs, while the temperature of high-energy electrons Ta decreases continuously.
