Sequential Analysis of an Erythropoietic Drive at High Altitude
No full text1990年, シシャパンマ峰(8027m)登山中の日本人隊員, 男性22名, 女性2名において, 低酸素刺激に対する造血系の賦活の動態を検討した. エリスロポエチン(以下, エポ)は, 高所到着後24時間以内に速やかに上昇し, その後より強い低酸素刺激に曝露される度に産生充進が認められ, 全経過において3峰性の変動を示した. C3(6920m)では, 平均575mU/mlに達した. また低酸素刺激が続くにもかかわらず, 2回のエポ・レベルの谷も認められた. エポによる造血系のパルス様刺激に伴い, 数日後に末梢血液中に網状赤血球数の増加が確認された. 網状赤血球数は登頂前の前進ベースキャンプ(5640m)にてピークを迎え, 造血能力の上限が示唆された. 最初のエポによる刺激から2週後に, ヘマトクリツトが有意に上昇し始めた. C3では平均64%に達し, うち4名では70%と著明な多血症を呈した. こうした造血のこう進に伴い徐々に鉄欠之に陥った. エポ分泌に関しては, 個人差が大きく, 低酸素に対する反応性, 反応量について厳密に遺伝的に規定されていることが示唆された. しかしながら, 21才から60才までの分布において, エポ産生能力, 造血能力に関しては年齢による差は認められなかった. 女性はいずれも低反応であった. 以上, 低酸素刺激に対するエポ産生応答の生理学的知見が多く得れ, 高所における造血のtime courseと多血の程度が明かとなった. 酸素運搬能力の改善という適応の面からは正の評価が与えられるが, 血液粘ちょう度のこう進のデメリットについて, 循環器系の適応や個々人の高山病症状との関連から今後検討をすすめる必要があると思われた
Effect of metal conditioner on bonding of porcelain to cobalt-chromium alloy
No full textPURPOSE: The purpose of this study was to evaluate the efficacy of two different metal conditioners for non-precious metal alloys for the bonding of porcelain to a cobalt-chromium (Co-Cr) alloy.
MATERIALS AND METHODS: Disk-shaped specimens (2.5×10.0 mm) were cast with Co-Cr alloy and used as adherend materials. The bonding surfaces were polished with a 600-grid silicon carbide paper and airborne-particle abraded using 110 µm alumina particles. Bonding specimens were fabricated by applying and firing either of the metal conditioners on the airborne-particle abraded surface, followed by firing porcelain into 5 mm in diameter and 3 mm in height. Specimens without metal conditioner were also fabricated. Shear bond strength for each group (n=8) were measured and compared (α=.05). Sectional view of bonding interface was observed by SEM. EDS analysis was performed to determine the chemical elements of metal conditioners and to determine the failure modes after shear test.
RESULTS: There were significant differences among three groups, and two metal conditioner-applied groups showed significantly higher values compared to the non-metal conditioner group. The SEM observation of the sectional view at bonding interface revealed loose contact at porcelain-alloy surface for non-metal conditioner group, however, close contact at both alloy-metal conditioner and metal conditioner-porcelain interfaces for both metal conditioner-applied groups. All the specimens showed mixed failures. EDS analysis showed that one metal conditioner was Si-based material, and another was Ti-based material. Si-based metal conditioner showed higher bond strengths compared to the Ti-based metal conditioner, but exhibited more porous failure surface failure.
CONCLUSION: Based on the results of this study, it can be stated that the application of metal conditioner is recommended for the bonding of porcelain to cobalt-chromium alloys.

An ecological momentary assessment analysis of relations among coping, affect, and smoking lapse:
No full textThis study used EMA data from smokers engaged in an earnest attempt to quit smoking to assess complex relations among coping, affect, and smoking. Analyses tested hypotheses about the main effects of coping and both mediators and moderators of coping effects on subsequent outcomes of interest (i.e., affect, coping effort, coping efficacy, and smoking behavior). Results of multilevel models indicated that coping does not improve negative affect within 4 hours of coping efforts, but that coping does improve positive affect and increase the odds of engaging in temptation coping in the short-term. Lapses were more likely to happen when recent coping was reported within 48 hours. None of the putative mediators of coping were predictive of later lapse risk as anticipated. Analyses also revealed that pre-quit coping practice moderated the effects of post-quit coping to deal with stressful events on later affect. Moreover, significant moderating gender effects were also found in these relations.M.S.Includes bibliographical references (p. 53-66)by Haruka Minam
BATHYMETRIC CHANGE OF DAILY HAULS PER BOAT IN RELATION TO DAILY CATCH BY THE DANISH SEINERS OF A FISH-MEAL FLEET FISHING IN THE BERING SEA
No full textRelations among affect, abstinence motivation and confidence, and daily lapse risk among smokers trying to quit
No full textAims: This study prospectively tested the hypothesis that changes in momentary affect, abstinence motivation, and confidence would predict lapse risk over the next 12-48 hours using Ecological Momentary Assessment (EMA) data from smokers attempting to quit smoking. The moderating effects of high-risk contexts on relations between cognitions (motivation and confidence) and lapse risk were also tested. Method: 79 adult, daily smokers recorded their momentary affect, motivation to quit, abstinence confidence, and smoking behaviors in near real time with multiple EMA reports using electronic diaries post-quit. Results: Multilevel models indicated that increases in negative affect predicted greater lapse risk up to 12 hours, but not 24 hours later. Neither positive nor negative affect had significant effects on subsequent cognitions. High levels of motivation appeared to reduce increases in lapse risk that occur over hours. Momentary increases in confidence predicted greater lapse risk over 12 hours in high-risk situations, but not in the absence of potent smoking triggers. Conclusion: Momentary changes in negative affect, motivation, and confidence, during a quit attempt all had short-term effects on smoking lapse. Negative affect had short-lived effects on lapse risk, whereas high levels of motivation protected against the risk of lapsing that accumulates over hours. Contrary to expectations, an acute increase in confidence may increase vulnerability to lapse in the context of potent smoking triggers. Relations observed among affect, cognitions, and lapse seem to depend critically on the timing of assessments and the contexts in which the assessments occur.Ph.
