Nature of self-diffusion in two-dimensional fluids
No full text© 2017 The Author(s). Published by IOP Publishing Ltd on behalf of Deutsche Physikalische Gesellschaft. Self-diffusion in a two-dimensional simple fluid is investigated by both analytical and numerical means. We investigate the anomalous aspects of self-diffusion in two-dimensional fluids with regards to the mean square displacement, the time-dependent diffusion coefficient, and the velocity autocorrelation function (VACF) using a consistency equation relating these quantities. We numerically confirm the consistency equation by extensive molecular dynamics simulations for finite systems, corroborate earlier results indicating that the kinematic viscosity approaches a finite, non-vanishing value in the thermodynamic limit, and establish the finite size behavior of the diffusion coefficient. We obtain the exact solution of the consistency equation in the thermodynamic limit and use this solution to determine the large time asymptotics of the mean square displacement, the diffusion coefficient, and the VACF. An asymptotic decay law of the VACF resembles the previously known self-consistent form, 1/(t√1nt, however with a rescaled time
An Analysis of the Contents of the Employee Publications of Five National Corporations and the Possible Immediate Effects They Produced on Employees, from 1932 to 1948
No full textWhile editor of an employee magazine for two-and-a-half years, the author became convinced that the editors of the more than 2000 industrial publications in the United States had urgent need of some accurate and simple method for determining what effects their publications were having on their readers. It was for the purpose of helping industrial editors develop such a method, that the author undertook this study. It is hoped that it will serve as a model for other editors and will help them establish a guide for their daily work
Data on the sequence-derived properties of gastric cancer – binding peptides
No full text© 2020 The Author(s) The article presents a dataset containing nine classes of calculated sequence-derived descriptors for 78 peptide sequences, 21 of which demonstrate the ability to bind with gastric cancer cells. The datasaet was used in the paper “A screening algorithm for gastric cancer binding peptides” [1] for the creation of a classification model that can predict the ability of a given peptide sequence to bind with gastric cancer cells. The 78 peptide sequences were extracted from a systematic literature search, and the various peptide descriptors were calculated using the R package “Peptides”. The nine calculated sequence-derived descriptor classes are the Blosum indices, Cruciani properties, FASGAI vectors, Kidera factors, ProtFP, ST-scales, T-scales, VHSE scales, and Z-scales. The resulting dataset, which is composed of over 4000 data points, offers a rich resource for further protochemometric analyses of the curated peptide sequences relevant to cancer diagnostics and therapeutics

First molecular detection of Hemolivia and Hepatozoon parasites in reptile-associated ticks on Iriomote Island, Japan
No full textHepatozoon and Hemolivia are members of the haemogregarines and are reported in reptiles and reptile-associated ticks. However, no studies have reported on Hepatozoon and Hemolivia in Japanese reptile-associated ticks. This study aimed to molecularly identify and to characterize Hepatozoon and Hemolivia in Japanese reptile-associated ticks, Amblyomma geoemydae (Cantor, 1847) and Amblyomma nitidum (Hirst & Hirst, 1910). A total of 41 and 75 DNA samples from A. geoemydae and A. nitidum ticks, respectively, were used for screening of Hepatozoon and Hemolivia with polymerase chain reaction targeting 18S rDNA. As a result, Hemolivia and Hepatozoon were detected in two A. geoemydae and one A. nitidum, respectively. The sequences of Hemolivia spp. showed a 99.5% (1,050/1,055 bp) identity with Hemolivia parvula (KR069083), and the Hemolivia spp. were located in the same clade as H. parvula in the phylogenetic tree. The sequences of Hepatozoon sp. showed a 98.4% (1,521/1,545 bp) identity with Hepatozoon colubri (MN723844), and the Hepatozoon sp. was distinct from validated Hepatozoon species in the tree. Our findings highlight the first molecular record of Hemolivia in Japan and present the first detection of Hepatozoon in A. nitidum. Further investigations on these tick-borne protozoa are required to understand their life cycle and pathogenicity

No full text二重束前十字靭帯再建術は脛骨回旋を改善させる： 2D/3Dレジストレーション法を用いたスクワット動作の解析
No full textBackground: The anterior cruciate ligament-deficient (ACLD) knee requires appropriate treatment for the patient to return to sports. The purpose of this study was to clarify the kinematics of the anterior cruciate ligament-deficient knee in squatting motion before and after double-bundle anterior cruciate ligament reconstruction (DB-ACLR) using a 2D/3D registration technique. Methods: The subjects of this study were 10 men with confirmed unilateral ACL rupture who underwent DB-ACLR. Computed tomography (CT) of the knee joints was performed before DB-ACLR. Fluoroscopic imaging of the knee motion in squatting before and after DB-ACLR was also performed. The 2D/3D registration technique is a method of calculating positional relationships by projecting the 3D bone model created from the CT data onto the image extracted from the fluoroscopic images. The tibial anteroposterior (AP) and rotational positions were analyzed with reference to the femur.
Results: The tibial AP position of the ACLD knees was significantly anterior to the contralateral knees (p = 0.015). The tibial rotational position of the ACLD knees was significantly internally rotated compared to the contralateral knees (p < 0.001). Both tibial AP and rotational positions improved after DB-ACLR (p < 0.001), with no significant differences compared to the contralateral knees. Conclusion: DB-ACLR improved not only tibial AP instability but also tibial rotational instability at knee flexion with weight-bearing. DB-ACLR appears to be a useful technique for normalizing the knee joint kinematics of ACLD knees.長崎大学学位論文 学位記番号:博(医歯薬)甲第1090号 学位授与年月日:平成30年9月5日Author: Kenichi Kidera, Akihiko Yonekura, Takeshi Miyaji, Yusuke Nakazoe, Kazuyoshi Gamada, Kei Yoneta, Futoshi Ikuta, Masato Tomita, Takashi Miyamoto, Shiro Kajiyama, Akira Hozumi, Ko Chiba, Narihiro Okazaki, Takayuki Shida and Makoto OsakiCitation: Journal of Orthopaedic Surgery and Research, 13, 111; 201
Differences in the flexion and extension phases during kneeling investigated by kinematic and contact point analyses: a cross-sectional study
No full textNagasaki University (長崎大学)博士(医学)Background: Kneeling is necessary for certain religious and ceremonial occasions, crouching work, and gardening, which many people take part in worldwide. However, there have been few reports about kneeling activities. The purpose of this study was to clarify the kinematics of kneeling.
Methods: The subjects were 15 healthy young males. Kneeling activity was analysed within a knee flexion angle from 100° to maximum flexion (maxflex, mean ± SD = 161.3 ± 3.2°). The kinematic and contact point (CP) analyses were performed using a 2D/3D registration method, in which a 3D bone model created from computed tomography images was matched to knee lateral fluoroscopic images and analysed on a personal computer.
Results: In the kinematic analysis, the femur translated 37.5 mm posteriorly and rotated 19.8° externally relative to the tibia during the knee flexion phase. During the knee extension phase, the femur translated 36.4 mm anteriorly, which was almost the same amount as in the knee flexion phase. However, the femur rotated only 7.4° internally during the knee extension phase. In the CP analysis, the amount of anterior translation of the CP in the knee extension phase was greater in the medial CP and smaller in the lateral CP than that of posterior translation in the knee flexion phase.
Conclusions: In kneeling, there was a difference in the rotational kinematics between the flexion phase and the extension phase. The kinematic difference between the flexion and extension phases may have some effect on the meniscus and articular cartilage.長崎大学学位論文 学位記番号:博(医歯薬)甲第1455号 学位授与年月日:令和4年6月1日Author: Yusuke Nakazoe, Akihiko Yonekura, Hiroyuki Takita, Takeshi Miyaji, Narihiro Okazaki, Ko Chiba, Kenichi Kidera, Takashi Miyamoto, Masato Tomita, Kazuyoshi Gamada and Makoto OsakiCitation: Journal of Orthopaedic Surgery and Research, 17, art. no. 192; 2022Nagasaki University (長崎大学), 博士(医学) (2022-06-01)doctoral thesi
