Nikita Babichev,Natalia Kirichenko 국립중앙과학관 2020 Journal of Asia-Pacific Biodiversity Vol.13 No.3
We reviewed the diversity and distribution of the gall-forming aphids of the genus Pemphigus developingon poplars in Eastern Siberia. As a result, the checklist of this group was compiled comprising 13 speciesdistributed in this macroregion that accounts about 29% of the world’s known poplar-feeding Pemphigusspecies. Biogeographical and host plant data are provided for all listed species. Pemphigus birimatusIvanovskaja, Pem. laurifoliae Dolgova, and Pem. matsumurai Monzen were documented for the first timein the Republic of Tuva. In addition, the latter two species were also discovered in the Republic ofBuryatia and Zabaikalskii Krai, respectively. Two poplars Populus sibirica and Pop. laurifolia wererecorded as novel hosts for 3 Pemphigus species. The origin of Pem. passeki Börner, Pem. spyrothecaePasserini, and Pem. microsetosus Aoki in Eastern Siberia remains unclear. Four species Pem. populiCourchet, Pem. bursarius (Linnaeus), Pem. matsumurai, and Pem. spyrothecae Lichtenstein cause noticeabledamage to poplars in man-made plantations.

Sixteen years progress in recanalization of chronic carotid artery occlusion: A comprehensive review
Stanishevskiy Artem,Babichev Konstantin,Savello Alexander,Gizatullin Shamil,Svistov Dmitriy,Davydov Denis 대한뇌혈관외과학회 2023 Journal of Cerebrovascular and Endovascular Neuros Vol.25 No.1
Objective: Although chronic carotid artery occlusion seems to be associated with significant risk of ischemic stroke, revascularization techniques are neither well established nor widespread. In contrast, extracranial-intracranial bypass is common despite the lack of evidence regarding neurological improvement or prevention of ischemic events. The aim of current review is to evaluate the effectiveness of various methods of recanalization of chronic carotid artery occlusion. Methods: Comprehensive literature search through PubMed, Scopus, Cochrane and Web of Science databases performed. Various parameters were assessed among patients underwent surgical, endovascular and hybrid recanalization for chronic carotid artery occlusion. Results: 40 publications from 2005 to 2021 with total of more than 1300 cases of revascularization of chronic carotid artery occlusion have been reviewed. Further parameters were assessed among patients underwent surgical, endovascular and hybrid recanalization for chronic carotid artery occlusion: mean age, male to female ratio, mean duration of occlusion before treatment, rate of successful recanalization, frequency of restenosis and reocclusion, prevalence of ischemic stroke postoperatively, neurological or other symptoms improvement and complications. Based on proposed through reviewed literature indications for revascularization and predictive factors of various recanalizing procedures, an algorithm for clinical decision making have been formulated. Conclusions: Although treatment of chronic carotid artery occlusion remains challenging, current literature suggests revascularization as single option for verified neurological improvement and prevention of ischemic events. Surgical and endovascular procedures should be taken into account when treating patients with symptomatic chronic carotid artery occlusion.

Instant single-photon Fock state tomography.
Huisman, S R,Jain, Nitin,Babichev, S A,Vewinger, Frank,Zhang, A N,Youn, S H,Lvovsky, A I Optical Society of America 2009 Optics letters Vol.34 No.18
<P>Heralded single photons are prepared at a rate of approximately 100 kHz via conditional measurements on polarization-nondegenerate biphotons produced in a periodically poled potassium-titanyl phosphate crystal. The single-photon Fock state is characterized using high-frequency pulsed optical homodyne tomography with a fidelity of (57.6+/-0.1)%. The state preparation and detection rates allowed us to perform on-the-fly alignment of the apparatus based on real-time analysis of the quadrature measurement statistics.</P>
