ミクロネシア連邦からグアムへの移民増大がもたらしている社会問題の一考察─米国のミクロネシア地域における政策とその責任─

For security and strategic purposes in the Pacific, the United States maintains a special bilateral agreement called the Compact of Free Association with each of the three states in Micronesia: the Federated States of Micronesia, the Republic of Marshall Islands and the Republic of Palau. The Compact grants citizens of these Freely Associated States （FAS）, migration privilege to the United States without a visa. The agreement is cause of "brain drain", and decrease of labor force, in the FAS. As the closest United States soil, Guam is often the first destination for the financially challenged emigrants from populous FSM. Due to its colony-like political status under the United States, with restrictive autonomy and lack of federal voting rights, the Compact has been a source of great financial burden to Guam, a territory which lacks the political ability to impose a fundamental solution to regional immigration issues.For security and strategic purposes in the Pacific, the United States maintains a special bilateral agreement called the Compact of Free Association with each of the three states in Micronesia: the Federated States of Micronesia, the Republic of Marshall Islands and the Republic of Palau.

A unique vacuolar processing enzyme responsible for conversion of several proprotein precursors into the mature forms

AbstractProprotein precursors of vacuolar components are transported from the endoplasmic reticulum into vacuoles, where they are proteolytically processed into their mature forms. However, the processing mechanism in plant vacuoles is very obscure. Characterization of a purified processing enzyme is required to determine whether a single enzyme is responsible for processing many vacuolar proteins with a large variability of molecular structure. If this is true, how can it recognize the numerous varieties of processing sites? We have now purified a processing enzyme (Mt=37 000) from castor bean seeds. Our results show that the purified enzyme can process 3 different proproteins isolated from either the endoplasmic reticulum or transport vesicles in cotyledon cells to produce the mature forms of these proteins which are found at different suborganellar locations in the vacuole: the 2S protein found in the soluble matrix, the 11S globulin found in the insoluble crystalloid and the 51 kDa protein associated with the membrane. Thus a single vacuolar processing enzyme is capable of converting several proprotein precursors into their respective mature forms

Low-Intensity Resistance Training with Moderate Blood Flow Restriction Appears Safe and Increases Skeletal Muscle Strength and Size in Cardiovascular Surgery Patients:A Pilot Study

We examined the safety and the effects of low-intensity resistance training (RT) with moderate blood flow restriction (KAATSU RT) on muscle strength and size in patients early after cardiac surgery. Cardiac patients (age 69.6 +/- 12.6 years, n = 21, M = 18) were randomly assigned to the control (n = 10) and the KAATSU RT group (n = 11). All patients had received a standard aerobic cardiac rehabilitation program. The KAATSU RT group additionally executed low-intensity leg extension and leg press exercises with moderate blood flow restriction twice a week for 3 months. RT-intensity and volume were increased gradually. We evaluated the anterior mid-thigh thickness (MTH), skeletal muscle mass index (SMI), handgrip strength, knee extensor strength, and walking speed at baseline, 5-7 days after cardiac surgery, and after 3 months. A physician monitored the electrocardiogram, rate of perceived exertion, and the color of the lower limbs during KAATSU RT. Creatine phosphokinase (CPK) and D-dimer were measured at baseline and after 3 months. There were no side effects during KAATSU RT. CPK and D-dimer were normal after 3 months. MTH, SMI, walking speed, and knee extensor strength increased after 3 months with KAATSU RT compared with baseline. Relatively low vs. high physical functioning patients tended to increase physical function more after 3 months with KAATSU RT. Low-intensity KAATSU RT as an adjuvant to standard cardiac rehabilitation can safely increase skeletal muscle strength and size in cardiovascular surgery patients.</p

Blood Flow Restriction Increases the Neural Activation of the Knee Extensors During Very Low-Intensity Leg Extension Exercise in Cardiovascular Patients:A Pilot Study

Blood flow restriction (BFR) has the potential to augment muscle activation, which underlies strengthening and hypertrophic effects of exercise on skeletal muscle. We quantified the effects of BFR on muscle activation in the rectus femoris (RF), the vastus lateralis (VL), and the vastus medialis (VM) in concentric and eccentric contraction phases of low-intensity (10% and 20% of one repetition maximum) leg extension in seven cardiovascular patients who performed leg extension in four conditions: at 10% and 20% intensities with and without BFR. Each condition consisted of three sets of 30 trials with 30 s of rest between sets and 5 min of rest between conditions. Electromyographic activity (EMG) from RF, VL, and VM for 30 repetitions was divided into blocks of 10 trials and averaged for each block in each muscle. At 10% intensity, BFR increased EMG of all muscles across the three blocks in both concentric and eccentric contraction phases. At 20% intensity, EMG activity in response to BFR tended to not to increase further than what it was at 10% intensity. We concluded that very low 10% intensity exercise with BFR may maximize the benefits of BFR on muscle activation and minimize exercise burden on cardiovascular patients

SDOP-DB: a comparative standardized-protocol database for mouse phenotypic analyses

Summary: This article reports the development of SDOP-DB, which can provide definite, detailed and easy comparison of experimental protocols used in mouse phenotypic analyses among institutes or laboratories. Because SDOP-DB is fully compliant with international standards, it can act as a practical foundation for international sharing and integration of mouse phenotypic information

Phospholipase Cbeta4 and protein kinase Calpha and/or protein kinase CbetaI are involved in the induction of long term depression in cerebellar Purkinje cells.

Activation of the type-1 metabotropic glutamate receptor (mGluR1) signaling pathway in the cerebellum involves activation of phospholipase C (PLC) and protein kinase C (PKC) for the induction of cerebellar long term depression (LTD). The PLC and PKC isoforms that are involved in LTD remain unclear, however. One previous study found no change in LTD in PKCgamma-deficient mice, thus, in the present study, we examined cerebellar LTD in PLCbeta4-deficient mice. Immunohistochemical and Western blot analyses of cerebellum from wild-type mice revealed that PLCbeta1 was expressed weakly and uniformly, PLCbeta2 was not detected, PLCbeta3 was expressed predominantly in caudal cerebellum (lobes 7-10), and PLCbeta4 was expressed uniformly throughout. In PLCbeta4-deficient mice, expression of total PLCbeta, the mGluR1-mediated Ca(2+) response, and LTD induction were greatly reduced in rostral cerebellum (lobes 1-6). Furthermore, we used immunohistochemistry to localize PKCalpha, -betaI, -betaII, and -gamma in mouse cerebellar Purkinje cells during LTD induction. Both PKCalpha and PKCbetaI were found to be translocated to the plasmamembrane under these conditions. Taken together, these results suggest that mGluR1-mediated activation of PLCbeta4 in rostral cerebellar Purkinje cells induced LTD via PKCalpha and/or PKCbetaI

ヨウチエン デノ プレイ セラピー ノ ジッセン ケンキュウ : ヨウジ ノ ソダツ チカラ ト コソダテ シエン トシテノ コウカ

Collaboration was organized between A university and two kindergartens in A city and play therapy was performed with nine children using empty kindergarten classrooms. University teachers with a clinical psychology qualification held discussions with the parents of these children, and kindergarten teachers provided consultation to the parents and exchanged information with them. The effectiveness of play therapy was verified on the basis of a questionnaire conducted before and after play therapy implementation. The results showed that after play therapy, the children became emotionally stable, had fewer behavior problems, and showed an improvement in their social nature. Moreover, seven out of the nine parents perceived that their children had matured. The kindergarten teachers presented the same evaluation from their results. The practice records showed that the children gained confidence and pride by enjoying playing with therapists and being accepted by them, which led to them taking interest in their friends. Their growth potential was activated. In addition, changes in parent−child relationships were observed. Play therapy also supported the parents, and it was considered an effective child raising support measure

Modified Bentall operation with bioprosthetic valve and Valsalva graft conduit:the "slit skirt" technique

We elucidated the efficacy of the slit skirt technique to prevent bleeding from the proximal anastomosis between the graft and aortic annulus. Between September 2008 and September 2014, 15 patients underwent a modified Bentall operation with the slit skirt technique at our institution. No patients had bleeding from the proximal anastomosis. No re-thoracotomy for bleeding was required. During midterm follow-up (median period, 21 months), no patient had pseudoaneurysms at the proximal suture line. We conclude that the slit skirt technique is useful to prevent bleeding from the proximal anastomosis after the Bentall operation
