Investigation of Antiphosphatidyl-Serine Antibody and Antiphosphatidyl-Inositol Antibody in Ischemic Stroke Patients

Antiphospholipid syndrome is characterized by arterial or venous thrombosis and the presence of antiphospholipid antibodies (aPL). We measured β2-GPI aCL, IgGaCL, LA, antiphosphatidyl-serine antibody (PS), and antiphosphatidyl-inositol antibody (PI) in each patient at one month after the onset of stroke. In addition, carotid artery echography was performed in patients positive for PI or PS. Among the 250 patients, 13.6% (34/250) were positive for either PI or PS, and 6.8% (17/250) were positive for both. Carotid artery echography performed on these 34 patients showed that the frequencies of increased intimal-medial thickness (IMT) of 1.1 mm or more, plaque, and carotid artery stenosis of 50% or more were all significantly higher in patients positive for antinuclear antibody than those negative for the antibody (P < .05). PI and PS are associated with antinuclear antibody and precipitation of atherosclerosis. Ischemic stroke patients with SLE frequently showed a variety of antiphospholipid-protein antibodies

1.インプレーの所要時間別比率では短いプレーは3部の試合が多く,長いプレーは1部の試合が多い。これは1部と3部のレベルの差によるところが大きいと考えられる。2.アウトプレーの所要時間別比率では,短い休止期では1部の試合が多く,長い休止期では3部の試合が多い。インプレーで述べたことと同じくレベルの差,特に体力的要素が大きく関与しているのではと考えられる。3.平成4年度のルール改正により,ゲーム中のプレー時間及び比率が増えた。4.プレー事象の中でキックの比率が最も多い。5.トライになる攻撃パターンはラックからが最も多い。6.モール,ラック,スクラム,ラインアウトの1試合の獲得率が高いチームが高い確立で勝利を収めている。7.サインプレーはあまり複雑なプレーはなく,クロスやダミークロス,飛ばしパスやフルバックのライン参加を組み合せたものが多い

For the defense in rugby foot boll, the focus tends to be put on the skill of tacking. Even the tackle is considered to be the goal of the defense. However, the take over of the ball in the scrimmage・line-out・ruck・maul should be the greatest goal. The attack saide may freely use a variety of strategies for gaining the line and try. To defend against attacks, the defense side has to respond to the move. Also, it has to react to the pass and kick. Therefore, it is said that the aim for the defense is to force the attack side to error. The Individual player is important, however, iudividual judgment for the defense tends to cause chaos. Thus, the defense should be organized in team strategy. This paper aims to summarize the defensive movements and discuss some of the unique strategies for the defense

Players of rugby football nowadays need to have very strong basic skills. Because the ways of playing the game are so diverse, practice time is usually relatively short and the conditions during the game so rapidly change. These basic skills are essential. No game can be well-organized without such a basis. The author will mention the basic skills in attack and defense in rugby football

AN ANGIOGRAPHICAL PREDICTOR FOR SUCCESSFUL RECANALIZATION

Background: Mechanical thrombectomy undoubtedly improves functional outcomes for patients with acute ischemic stroke. Although we have observed occlusion sites that protrude proximally into the vessel on angiography, termed the “claw sign,” we have been unable to state its clinical significance. In this study, we aimed to determine whether the presence of a claw sign was related to recanalization success after mechanical thrombectomy. Materials and Methods: We retrospectively included 73 consecutive patients treated for acute cerebral large vessel occlusion by mechanical thrombectomy between January 2014 and December 2017. The angiographic claw sign was defined as a thrombus that protruded proximally by more than half the diameter of the parent artery. Claw sign positivity, clinical and etiological features, and outcomes were compared between groups with and without recanalization. Results: The claw sign was observed in 29 of 73 (40%) patients and was positive significantly more frequently in those with recanalization (50.0%) than in those without recanalization (5.9%) (P < .01). By multivariate analysis, the claw sign was the only pretreatment parameter to predict successful recanalization (odds ratio, 12.50; 95% confidence interval, 1.50-103.00; P = .019). Conclusions: The presence of the claw sign might predict successful recanalization in patients undergoing mechanical thrombectomy for large vessel occlusion

FUSION IMAGE AND IA ICG IN AVM SURGERY

Objective: An understanding of the complex morphology of an arteriovenous malformation (AVM) is important for successful resection. We have previously reported the utility of intra-arterial indocyanine green (ICG) videoangiography for this purpose, but that method cannot detect the angioarchitecture covered by brain tissue. 3-dimensional (3D) multimodal fusion imaging is reportedly useful for this same purpose, but cannot always visualize the exact angioarchitecture due to poor source images and processing techniques. This study examined the results of utilizing both techniques in patients with AVMs. Methods: Both techniques were applied in 12 patients with AVMs. Both images were compared with surgical views and evaluated by surgeons. Results: Although evaluations for identifying superficial feeders by ICG videoangiography were high in all cases, the more complicated the AVM, the lower the evaluation by 3D multimodal fusion imaging. Conversely, evaluation of the estimated range of the nidus was high in all cases by 3D multimodal fusion imaging, but low in all but one case by ICG videoangiography. Nidus flow reduction was recognized by Flow 800 analysis obtained after ICG videoangiography. Conclusions: These results showed that utilizing both techniques together was more useful than each modality alone in AVM surgery. This was particularly effective in identifying superficial feeders and estimating the range of the nidus. This technique is expected to offer an optimal tool for AVM surgery

Effects of ultradian variation on smoking behavior

The purpose of this study is to examine the enhancement model of smoking maintenance, which has been proposed by Mangan & Golding (1978). We studied the relationships of the ultradian variations among the smoking behavior and sleepiness. The results were as follows. (1) The results of the time series analysis revealed that several spectral peaks were obtained in day time fluctuations of smoking behavior, sleepiness, mood and task performance. The average peak frequency for each parameter distributed in the range of 10 to 14 cycle/day (c/d : See Fig. 3-6). (2) The significant correlations were obtained between the parameters of the smoking behavior (frequency of puffing and VAS score of need for smoking) and the daytime sleepiness (VAS score). The significant average correlation coefficients between smoking need and sleepiness were observed (See Table 2). In general, present results agree with the enhancement model of smoking maintenance
