Abstract
Protein phosphatase 6 is a Ser/Thr protein phosphatase and its catalytic subunit is Ppp6c. Ppp6c is thought to be indispensable for proper growth of normal cells. On the other hand, loss of Ppp6c accelerates growth of oncogenic Ras-expressing cells. Although it has been studied in multiple contexts, the role(s) of Ppp6c in cell proliferation remains controversial. It is unclear how oncogenic K-Ras overcomes cell proliferation failure induced by Ppp6c deficiency; therefore, in this study, we attempted to shed light on how oncogenic K-Ras modulates tumor cell growth. Contrary to our expectations, loss of Ppp6c decreased proliferation, anchorage-independent growth in soft agar, and tumor formation of oncogenic Ras-expressing mouse embryonic fibroblasts (MEFs). These findings show that oncogenic K-RasG12V cannot overcome proliferation failure caused by loss of Ppp6c in MEFs.

Abstract
Protein phosphatase 6 (PP6) is a serine/threonine (Ser/Thr) protein phosphatase, and its catalytic subunit is Ppp6c. PP6 forms the PP2A subfamily with PP2A and PP4. The diverse phenotypes observed following small interfering RNA (siRNA)-based knockdown of Ppp6c in cultured mammalian cells suggest that PP6 plays roles in cell growth and DNA repair. There is also evidence that PP6 regulates nuclear factor kappa B (NF-κB) signaling and mitogen-activated protein kinases and inactivates transforming growth factor-β-activated kinase 1 (TAK1). Loss of Ppp6c causes several abnormalities, including those of T cell and regulatory T cell function, neurogenesis, oogenesis, and spermatogenesis. PP2A has been reported to play an important role in erythropoiesis. However, the roles of PP6 in other hematopoietic cells have not been investigated. We generated Ppp6cfl/fl;Tie2-Cre (Ppp6cTKO) mice, in which Ppp6c was specifically deleted in hematopoietic and vascular endothelial cells. Ppp6cTKO mice displayed embryonic lethality. Ppp6c deficiency increased the number of dead cells and decreased the percentages of erythroid and monocytic cells during fetal hematopoiesis. By contrast, the number of Lin-Sca-1+c-Kit+ cells, which give rise to all hematopoietic cells, was slightly increased, but their colony-forming cell activity was markedly decreased. Ppp6c deficiency also increased phosphorylation of extracellular signal-regulated kinase 1/2 and c-Jun amino (N)-terminal kinase in fetal liver hematopoietic cells.

Abstract
Ceramides are major constituents of stratum corneum (SC) intercellular lipids involved in skin barrier function. The ratio of molecular species of ceramides and their correlation with disease severity was examined in patients with atopic dermatitis (AD). Thirty-eight patients with AD and 32 healthy controls (HCs) were assessed for transepidermal water loss, SC collection and clinical assessment. The ceramide content of different molecular species in the samples was quantified using high-performance liquid chromatography coupled with tandem mass spectrometry. Unsaturated acyl chains of both covalently bound and free ceramides [EOS] were higher in AD lesional skin than those in AD non-lesional or normal HC skin. The proportion of unsaturated acyl chains (C30:1, C32:1 and C34:1) was higher than other ceramide molecular species among covalently bound and free ceramides [EOS] in patients with AD. The proportion of unsaturated acyl chains in covalently bound ceramides was positively correlated with transepidermal water loss (r = 0.600) when considering the total number of non-lesional and lesional skin. Additionally, thymus and activation-regulated chemokine (TARC) showed a positive correlation with unsaturated acyl chains proportion in AD non-lesional (r = 0.676) and lesional (r = 0.503) skin. Our study is the first to show the increase in unsaturated acyl chains of both covalently bound and free ceramides [EOS] in lesional and non-lesional skin in AD for each molecular species. This increase is associated with dryness and impaired barrier function, which correlates with TARC levels, a marker for the degree of type 2 inflammation. We speculate that type 2 inflammation exacerbation leads to abnormal epidermal lipid metabolism in the skin of patients with AD.

Abstract
We analyzed the results of a nationwide questionnaire administered to 699 stimulant offenders and examined sex differences in the association between various psychosocial problems and treatment history for substance use disorder. Based on their attributes, we predominantly evaluated the treatment and support provided to women with substance use disorder. The rates of childhood (before the age of 18) traumatic experiences (physical, psychological, and sexual abuse and neglect) and lifetime intimate partner violence were significantly higher in women than in men. The history of treatment for substance use disorder was also significantly higher in women than in men, at 15.8% for men and 42.4% for women [χ2 (1) = 41.223, p < 0.001]. Logistic regression analysis was performed using the treatment history of substance use disorder as the dependent variable. The results showed that treatment history was significantly associated with the total drug abuse screening test-20 score and suicidal ideation in men and with survivors of child abuse and eating disorders in women. A comprehensive assessment is required for several issues, such as child abuse, domestic violence, trauma symptoms, eating disorders, and drug problems. Moreover, an integrated treatment for substance use disorder, trauma, and eating disorders is required for female stimulant offenders.

Abstract
Plastic surgeons require experience in supermicroscopic vascular anastomosis. Herein, we report a simple, rapid, and cost-effective training method using chicken wings and colored water. The avian ventral metacarpal artery was selected for dissection and anastomosis to mimic supermicrosurgery. Over 14 weeks (one anastomosis per day), the ulnar artery in 100 chicken wings was exposed by dissection, cut proximally, and injected with blue food dye-colored water by an inexperienced surgeon. After ligating the artery branches, it was cut and subjected to end-to-end anastomosis. Next, colored water was injected into the ulnar artery to check for suture sufficiency. The vessel was re-dissected to inspect the lumen and sutures qualitatively. Of the 100 wings, the first and last 20 wings' ventral metacarpal artery dissection, anastomosis times, and leakage frequency were compared. Avian ventral metacarpal artery diameter was recorded, and the cumulative anastomosis time where individual anastomosis times started decreasing was determined. Leakage rates before and after this point were compared. The avian ventral metacarpal artery diameter was 0.7-0.8 mm. The last 20 wings had significantly shorter median dissection times (12:27 vs. 17:45 min), anastomosis times (9:02 vs. 12:29 min), and leakage rates (15% vs. 70%); more even stitching and parallel ligature points; and less vessel layer inversion than the first 20 wings. After a cumulative anastomosis time of 10 h 26 min, individual times sharply decreased, and the leakage rate decreased significantly (58.3% vs. 23.8%). The proposed method significantly improved supermicrosurgical anastomosis. Thus, we believe that this method will help surgeons improve their supermicrosurgical skills.

Abstract
BACKGROUND Adverse childhood experiences (ACEs) are distressing and/or traumatic events that occur during childhood that increase the risk of negative health outcomes in adulthood. OBJECTIVE This study estimated the prevalence of ACEs in a nationwide sample of Japanese methamphetamine users in prison and examined associations among ACEs, suicidal ideation, and non-suicidal self-injury. PARTICIPANTS AND SETTING Participants were 636 inmates (418 male and 218 female) who were newly incarcerated in Japan for Stimulants Control Act violations. METHODS First, 699 participants completed an anonymous self-report questionnaire. Of these, 636 participants who did not have any missing responses were included in the analysis. After calculating descriptive statistics, the associations between ACEs and suicidal behaviors were assessed using binary logistic regression analyses. RESULTS Results showed that 76.1 % of the participants reported at least one ACE before the age of 18, and female participants reported a significantly higher number of adversities than their male counterparts. The most common ACEs were parental death or divorce, followed by psychological abuse. Logistic regression analyses revealed that ACE scores significantly increased the risk of suicidal ideation (SI; adjusted odd ratio [AOR] = 1.18, p < .001) and non-suicidal self-injury (NSSI; AOR = 1.18, p < .001) after controlling for possible confounding variables. CONCLUSIONS Findings suggest the importance of early prevention and intervention for traumatic experiences, and have implications for the recommendation of gender-responsive, trauma-focused interventions, especially for female inmates in the criminal justice system, to break the intergenerational chain of abuse. Future research directions and treatment are discussed.

Abstract
This study aimed to examine the relationship between methamphetamine (MA) use and high-risk sexual behavior among newly incarcerated prisoners in Japan. We conducted a secondary analysis using cross-sectional survey data, which constituted a nationwide prison sample surveyed between July and November 2017. In total, 699 participants (462 male and 237 female prisoners), who completed the self-administered questionnaire during imprisonment were recruited for the study. The prevalence of high-risk sexual behaviors was as follows: inconsistent condom use (78.4% male, 81.7% female), multiple sexual partners (61.3% male, 41.3% female), history of sexually transmitted diseases (14.1% male, 23.6% female), and trading sex for drugs (15.6% male, 17.7% female). A logistic regression analysis showed that MA use during sex increased the likelihood of high-risk sexual behavior in both male (adjusted odds ratio [AOR] = 5.86; 95% confidence interval [CI] = 3.41-10.07) and female prisoners (AOR = 2.58; 95% CI = 1.33-5.00). Additionally, in female prisoners, a history of sharing MA injection (AOR = 1.60; 95% CI = 1.06-2.42) increased high-risk sexual behavior. Our results indicate that harm reduction programs tailored according to the specific necessities of each gender to reduce high-risk sexual behaviors among MA users should be included in Japanese drug policies.

Abstract
BACKGROUND Consuming drugs in conjunction with sexual intercourse may shape the perceived interdependence of drug use and sexual intercourse (PIDS). Additionally, the severity of drug problems may have a significant impact on PIDS. However, this relationship remains unverified. Therefore, this study investigates whether the severity of drug problems is associated with PIDS among adult males in drug addiction rehabilitation centers (DARC) in Japan. METHODS This study was a secondary analysis of the "DARC Follow-Up Study in Japan" conducted by the National Center of Neurology and Psychiatry in 2016, in which participants from 46 facilities completed a self-report questionnaire. A total of 440 males with drug dependence were included in the analysis. We analyzed participants' demographic characteristics, history of sexually transmitted disease diagnoses, and responses to questions related to drug use (e.g., primary drug use and PIDS). Additionally, we measured the severity of drug problems using the Japanese version of the Drug Abuse Screening Test-20 (DAST-20). RESULTS The median age of the participants was 42 years. The median DAST-20 score was 14.0, the primary drug was methamphetamine (61.4%) and new psychoactive substances (NPS: 13.6%). Multivariate analysis indicated that participants' experiences with unprotected sexual intercourse ("mostly a non-condom user": adjusted odds ratio (AOR) = 4.410), methamphetamine use (AOR = 3.220), new psychoactive substances use (AOR = 2.744), and the DAST-20 score (AOR = 1.093) were associated with PIDS. CONCLUSIONS This study indicated that the frequency of unprotected sexual intercourse under the influence of drugs, methamphetamine and NPS use were strongly associated with PIDS. The severity of drug problems was also significantly associated with PIDS. It is necessary to develop culturally appropriate treatment programs adapted to the needs of patients who experience strong PIDS.

Abstract
There are a few studies on gender differences in terms of reasons and motives for methamphetamine use. Purpose/Objectives: To examine gender differences in triggers of methamphetamine use Methods: We provided a questionnaire survey to 699 inmates who were incarcerated because of violation of the Stimulants Control Act. Results: The results of DAST-20 (the severity of drug dependence) moderately correlated with the applicable numbers of the 37 situational triggers and 34 emotional triggers for stimulant use, respectively. Regarding gender differences, items including "when having sex" [46.3% (men) vs. 25.3% (women)], "when I have some money" (39.4% vs. 25.3%), and "after getting paid from work" (22.1% vs. 11.4%) were applicable in a significantly higher proportion in males (p < 0.001 and p = 0.008, respectively), whereas items including "worried about the body shape" (3.5% vs. 31.2%) and "after quarreling with someone" (11.7% vs. 29.1%) were applicable in a significantly higher proportion in females (p < 0.001 for both comparisons). Further, most trigger (emotions) items that exhibited gender differences were significantly higher in females. Many females answered that they had used drugs to relieve discomfort symptoms associated with menstrual periods. Conclusions/Importance: Thus, the awareness of important factors including learning how to deal with negative emotions (e.g. depression), repairing self-image, and recognizing physical and emotional changes associated with the menstrual cycle is helpful in providing proper care and treatment of drug addiction in females.

BACKGROUND The experiences of foreign nurses in host countries, and the challenges they face, have been widely investigated around the world. However, no systematic review has focused on the experience of foreign-educated nurses in Japan. METHODS A systematic literature review was conducted by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Guidelines. Japan Medical Abstract Society, Citation Information by National Institute of Informatics, Cumulative Index to Nursing and Allied Health Literature, and PubMed databases were used for the literature search. Inclusion criteria were research articles published between 2013 and 2020 written in Japanese or English. A quality assessment was performed using Version 2018 of the Mixed Methods Appraisal Tool. Selected articles were read repeatedly, and relevant contents were extracted and summarized thematically. RESULTS Twenty-five studies were selected for the review. The themes generated included (1) reasons for nurses to come to Japan, (2) experiences and current situations among the Economic Partnership Agreement nurses/nurse candidates living in Japan, and (3) experiences and current situation of nurses who had returned to their home countries. The second theme was classified into four categories: language and communication barriers, low pass rates for the national qualification exam, adaptation to workplaces and social environments, and psychological distress. CONCLUSION Foreign nurses in Japan face various challenges and difficulties, even after they return to their home countries. Solving these problems may improve the wellbeing of foreign-educated nurses in Japan. IMPLICATIONS FOR NURSING POLICY The results from the current review highlight the necessity for immediate intervention by policymakers to improve the current support system for Economic Partnership Agreement nurses/nurse candidates. A thorough pre-arrival orientation should be provided for the nurse candidates to able them to make a well-informed choice.

Abstract
BACKGROUND Even if a living donor candidate exists, there are some cases that do not result in kidney transplantation (KTx) due to problems on the recipient side. The aim of this study was to clarify causes of ineligibility for KTx in these cases, so as to make RTx more applicable for patients. METHODS We targeted 470 patients with end-stage renal disease who applied for the primary kidney KTx from 2010 to 2012. Then we selected those who were not applicable for KTx and investigated recipient causes of ineligibility for KTx or not receiving KTx. RESULTS The average age of recipients was 47.6 ± 12.9 (7-82) years. A majority of the 470 patients were male (n = 305, 64.9%). Two hundred ninety-seven patients intended to receive a living donor KTx and the others hoped for a deceased donor KTx. Of the 297 patients, 207 (70.0%) underwent KTx and 9 (1.9%) were being prepared for KTx at the time of the survey. Eighty-three patients (27.9%) did not receive a living KTx, with 59 of these due to recipient-related problems and 30 due to donor-related problems. We further classified the reasons for these 59 recipients not undergoing KTx as follows: (1) unclear reasons (35.6%); (2) insufficient intention to receive transplant (13.6%); (3) heart disease (10.2%); (4) malignancy (8.5%); (5) immunologic risks (5.1%); (6) death during the waiting period (5.1%); (7) cerebrovascular events (5.1%); (8) cardiovascular problems (5.1%); (9) psychiatric disorders (3.4%); and (10) infections (3.4%). CONCLUSION Nearly 50% of the reasons for ineligibility as a recipient were related to their intention to receive KTx, with 94.9% of the nontransplanted cases due to nonimmunologic reasons. Thanks to the recent advances in immunosuppressive therapy, there were only 3 patients who could not undergo KTx due to immunologic risks. Based on these results, transplant surgeons should not only emphasize physical evaluation but should also pay careful attention to the recipient's intention to receive KTx.

Abstract
The yeast Saccharomyces cerevisiae cannot utilize xylose, but the introduction of a xylose isomerase that functions well in yeast will help overcome the limitations of the fungal oxido-reductive pathway. In this study, a diploid S. cerevisiae S288c[2n YMX12] strain was constructed expressing the Bacteroides thetaiotaomicron xylA (XI) and the Scheffersomyces stipitis xyl3 (XK) and the changes in the metabolite pools monitored over time. Cultivation on xylose generally resulted in gradual changes in metabolite pool size over time, whereas more dramatic fluctuations were observed with cultivation on glucose due to the diauxic growth pattern. The low G6P and F1,6P levels observed with cultivation on xylose resulted in the incomplete activation of the Crabtree effect, whereas the high PEP levels is indicative of carbon starvation. The high UDP-D-glucose levels with cultivation on xylose indicated that the carbon was channeled toward biomass production. The adenylate and guanylate energy charges were tightly regulated by the cultures, while the catabolic and anabolic reduction charges fluctuated between metabolic states. This study helped elucidate the metabolite distribution that takes place under Crabtree-positive and Crabtree-negative conditions when cultivating S. cerevisiae on glucose and xylose, respectively.

Abstract
We have carried out hard x-ray photoemission spectroscopy (HAXPES) of Yb1-x Zr x B12 ([Formula: see text]) to study the effects of electron doping on the Kondo insulator YbB12. The Yb valences of Yb1-x Zr x B12 at 300 K estimated from the Yb 3d HAXPES spectra decreased after substituting Yb with Zr from 2.93 for YbB12 to 2.83 for Yb0.125Zr0.875B12. A temperature dependent valence decrease was found upon cooling for all doping concentrations. We found peak shifts of the B 1s and Zr 3d5/2, and Yb3+ 4f spectra toward the deeper binding-energy with increasing Zr concentration, which indicates a shift of the Fermi level to the higher energy and that of the Yb 4f hole level close to the Fermi level, respectively, due to electron doping. These results qualitatively show the enhanced hybridization between the Yb 4f and conduction-band states with Zr substitution, consistent with magnetic susceptibility measurements.

Abstract
CASE REPORT A 30-year-old Japanese nulliparous woman visited for pregnancy at 33 weeks with a massive ovarian tumor located in the pouch of Douglas. By preoperative screening, her prothrombin time (PT) and activated partial thromboplastin time (APTT) were prolonged, and her FV activity was significantly decreased to 4.8%. After prophylactic FFP 20 ml/kg was administered and her FV factor was 19.3%, cesarean delivery was performed, and her perioperative course was uneventful. One year later, she underwent a dilatation and evacuation because of a missed abortion, although prophylactic FFP was not administered. During a third pregnancy, after prophylactic FFP 20 ml/kg was administered and FV activity increased to 21.1%, elective cesarean delivery was performed, and her postoperative course was uneventful. CONCLUSION For surgical therapy or delivery, the goal of therapy is to maintain FV activity above 20%. It is particularly useful to administer prophylactic FFP.

Abstract
The Serigaya Methamphetamine Relapse Prevention Program (SMARPP) cognitive behavioral therapy was implemented among 38 substance. abusers in 12-Step Program Treatment Centers operated by:the Drug Addiction Rehabilitation Center (DARC). Tochigi DARC members (20 patients) started SMARPP after attending daily programs in the treatment centers for an extended time (mean period, 17.4 months). Chiba and Tateyama DARC members (18 patients) started SMARPP soon after initiation of treatment (mean period, 1.2 months). We provided SMARPP for approximately 70 days in the treatment centers, in addition to the regular programs, and examined changes in the participants before and after SMARPP. The results showed that the Tochigi DARC members improved significantly after 70 days based on scores from the "taking steps" subscale of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) (Wilcoxon rank sum test, p=0.041) and the "tension-anxiety" subscale of the Profile of Mood States (POMS) (Wilcoxon rank sum test, p=0.004). However, the Chiba and Tateyama DARC members did not improve. In the 12-Step Program Treatment Centers, cognitive behavioral therapy-such as SMARPP seems to be more effective if it is implemented later rather immediately after regular programs.

Abstract
A cognitive behavioral therapy program entitled "STEM" was implemented with 42 drug dependent outpatients at Okayama Psychiatric Medical Center. Characteristics of 1 group who completed the program were examined, with the effectiveness of the program evaluated through monitoring longitudinal changes over a period of 8.5 months. Results showed that the percentage of patients who completed the program was 52.4% (22 out of 42 people), those who completed had a longer educational history than the dropouts, a high proportion of those who completed held some form of employment and that their motivation to recover was high. Evaluation results of the program effectiveness showed significant improvement in short-term drug self-efficacy, with a tendency for later improvement in feelings and emotions also observed. While a certain level of effectiveness was proven, approximately half the group dropped out; so it is necessary to consider alternative options at an early stage for participants with a high risk of dropout, such as strengthening individual support based on their specific characteristics.

Abstract
The increasing number of law-evading drug users in Japan is becoming a serious social problem. Previous studies have shown that law-evading drug users are younger, more educated, and less antisocial than methamphetamine users. They also tend to have some type of psychiatric disorder before starting drug use; therefore one of the reasons that they start using drugs may be to alleviate certain psychiatric symptoms. Furthermore, if drug users are successful in avoiding arrest, they often lack the motivation to stop, which makes treatment difficult. Therapists are required to be non-confrontational, to keep pace with their patients, and to take their patients' other existing disorders into account. Recently, the Matrix Model has shown promise as a new treatment strategy for drug abusers in Japan. The Matrix Model, which was originally developed in response to the 1980s cocaine epidemic in the USA, is an intensive outpatient treatment approach for drug abuse and dependence. The Matrix Model integrates cognitive-behavioral therapy, contingency management, motivational interviewing, 12-step facilitation, family involvement, and so on, with a directive, non-confrontational approach, and this style of therapy seems to fit with law-evading drug users. A Matrix Model-based treatment program was first established in Japan in 2006. The aim of this report is to introduce and assess the benefits of the TAMA Mental Health and Welfare Center Relapse Prevention Program, a Matrix Model-based treatment program established at the Tama Mental Health and Welfare Center in 2007.

Abstract
Metal oxide and quantum dot (QD) heterostructures have attracted considerable recent attention as materials for developing efficient solar cells, photocatalysts, and display devices, thus nanoscale imaging of trapped electrons in these heterostructures provides important insight for developing efficient devices. In the present study, Kelvin probe force microscopy (KPFM) of CdS quantum dot (QD)-grafted Cs4W11O36(2-) nanosheets was performed before and after visible-light irradiation. After visible-light excitation of the CdS QDs, the Cs4W11O36(2-) nanosheet surface exhibited a decreased work function in the vicinity of the junction with CdS QDs, even though the Cs4W11O36(2-) nanosheet did not absorb visible light. X-ray photoelectron spectroscopy revealed that W(5+) species were formed in the nanosheet after visible-light irradiation. These results demonstrated that excited electrons in the CdS QDs were injected and trapped in the Cs4W11O36(2-) nanosheet to form color centers. Further, the CdS QDs and Cs4W11O36(2-) nanosheet composite films exhibited efficient remote photochromic coloration, which was attributed to the quantum nanostructure of the film. Notably, the responsive wavelength of the material is tunable by adjusting the size of QDs, and the decoloration rate is highly efficient, as the required length for trapped electrons to diffuse into the nanosheet surface is very short owing to its nanoscale thickness. The unique properties of this photochromic device make it suitable for display or memory applications. In addition, the methodology described in the present study for nanoscale imaging is expected to aid in the understanding of electron transport and trapping processes in metal oxide and metal chalcogenide heterostructure, which are crucial phenomena in QD-based solar cells and/or photocatalytic water-splitting systems.

Abstract
The development of an effective treatment system for patients with addiction-related problems like substance abuse or pathological gambling is urgently needed. The purpose of this study was to clarify the therapeutic factors of the Tama Mental Health and Welfare Center Relapse Prevention Program (TAMARPP). The program is provided at the Tama Comprehensive Center for Mental Health and Welfare, which is operated publicly by the Tokyo Metropolitan Government. Seven personnel (3 clinical psychologists, 2 public health nurses, and 2 recovering counselors) searched the consultation records of 31 participants who had continued treatment longer than 1 year, and made a list of qualitative factors that may positively impact participant outcome. The following six factors were extracted: 1) a "no-blame" atmosphere that makes participants feel safe and free; 2) a mutual helping process that enables participants to empathize with one another; 3) an individual-centered approach that focuses on a participant's motivation to recover; 4) a psycho-educational process that establishes treatment goals; 5) a treatment goal that involves some type of social role; and 6) the referral of graduates to another long-term treatment program such as Narcotics Anonymous. Our results suggest the need of personnel to provide treatment as follows: 1) keep the circumstances safe; 2) use a method that matches the participant's motivation; 3) refer graduates to another in-depth treatment program; 4) emphasize the relationship between thinking, emotion, and behavior; and 5) improve the quality of life of the participant. The missions of our center, an official institution that runs such a program, are as follows: 1) to be the first place at which addicts seek aid during the early stage; 2) to cooperate with other facilities in order to provide social resources that support recovery; and 3) to support patients suffering from both addiction and comorbid psychiatric diseases.

Abstract
We developed the TAMA mental health and welfare center Relapse Prevention Program (TAMARPP) and evaluated the efficacy of the program. We provided the program for 59 substance abusers at Tokyo Tama Comprehensive Mental Health and Welfare Center, and conducted brief interviews and questionnaire surveys to them four times during eight months follow-up period. The main results were as follows. 1) Most of the subjects were before "hitting bottom". 2) More than half of the subjects continued participating in the program for more than 2 months and their attendance rate was fairly high. 3) Some of the subjects began joining a self-help group as N.A. and A.A. during the follow up period. 4) The mood states of the subjects were gradually improved during the period. 5) About one-third of the subjects abused substance again after two-month' program, but all of them continued to attend the program or a private counseling. Most of their families also continued having support from the center. These findings suggested it was meaningful to have such a friendly and less confrontational program as TAMARPP at our center to provide support for many substance abusers before "hitting bottom" and their families.

Abstract
We previously demonstrated that thrombin stimulates synthesis of interleukin 6 (IL6), a potent bone resorptive agent, in part via p44/p42 MAP kinase and p38 MAP kinase but not through stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK) among the MAP kinase superfamily in osteoblast-like MC3T3-E1 cells. In this study, we investigated the involvement of AMP-activated protein kinase (AMPK), a regulator of energy metabolism, in thrombin-stimulated IL6 synthesis in MC3T3-E1 cells. The phosphorylation of p44/p42 MAP kinase, p38 MAP kinase, SAPK/JNK, or AMPK was determined by western blot analysis. The release of IL6 was determined by the measurement of IL6 concentration in the conditioned medium using an ELISA kit. The expression of IL6 mRNA was determined by RT-PCR. Thrombin time dependently induced the phosphorylation of AMPK α-subunit (Thr-172). Compound C, an inhibitor of AMPK, dose-dependently suppressed the thrombin-stimulated IL6 release in the range between 0.3 and 10 μM. Compound C reduced thrombin-induced acetyl-CoA carboxylase phosphorylation. The IL6 mRNA expression induced by thrombin was markedly reduced by compound C. Downregulation of AMPK by siRNA suppressed the thrombin-stimulated IL6 release. The thrombin-induced phosphorylation of p44/p42 MAP kinase and p38 MAP kinase was inhibited by compound C, which failed to affect SAPK/JNK phosphorylation. These results strongly suggest that AMPK regulates thrombin-stimulated IL6 synthesis via p44/p42 MAP kinase and p38 MAP kinase in osteoblasts.

Abstract
PURPOSE Since 2006, we have been performing minimally invasive plate osteosynthesis with a palmar locking plate and without division of the pronator quadratus muscle for repairing distal radial fractures. The purpose of this study was to present the surgical technique we have developed and to retrospectively evaluate the clinical outcomes. METHODS Twenty patients were treated with this technique between January and December 2007. The range of motion of the wrist and forearm, grip strength, and the quick disability of the arm, shoulder, and hand score were assessed at the latest follow-up examination, and postoperative complications were evaluated. RESULTS The average ranges of flexion and extension of the wrist were 55° and 60°, respectively. The average ranges of supination and pronation of the forearm were 88° and 86°, respectively. The average grip strength of the treated side was 71 % of that of the uninjured side. The average quick disability of the arm, shoulder, and hand score was 13.4 points. No patient had loss of fracture reduction, implant failure, deep infection, or tendon or nerve problems. CONCLUSIONS The small skin incisions of this technique are advantageous from the aesthetic viewpoint. Minimally invasive plate osteosynthesis is one of the options for the treatment of distal radial fractures.

Abstract
The effects of charged residues in peptide antigens on the binding characteristics of polyclonal antipeptide antibodies were studied using immunoadsorbents prepared by coupling the antibodies to CNBr-activated Sepharose 4B. Among the antipeptide antibodies, an antibody to the peptide without charged residues showed the most stable interaction with the peptide to the changes in pH. Conversely, the binding affinity of antibodies to the pep-tides with histidine residues having a unique pKa value of 6.0 decreased steeply with pH at around 6.0. The binding affinity of an antibody to the peptide with many charged residues decreased steeply with an increase in the ionic strength (adjusted by NaCl). Since circular dichroism (CD) spectrum measurements indicate that these peptides show disordered structures in the pH range of adsorption measurement, the dependence of peptide-antibody interaction on environmental conditions is attributed to the characteristics of side chains of the peptides. These results indicate that the dependence of the binding affinity of antipeptide antibodies on pH and the ionic strength is dominantly affected by the number and the pKa values of charged residues in the peptides.

Abstract
The relapse prevention program named TAMARPP is provided for drug addicts at Tama comprehensive center for mental health and welfare. The TAMARPP is a group cognitive therapy based on manual and simple textbook. We are going to present the outline of the TAMARPP, and discuss the effectiveness of this program from the findings of clinical observation on 15 variables. Both of the treatment-retain rate and abstinence rate during the term to attend this program turns is rather high. This textbook-based program appears to be relatively easy for beginner therapists to conduct group sessions and to support drug addicts. The TAMARPP has possibility to prevail to perform in the other public health institutions.

Abstract
This study explores the effect of priming rhesus monkeys with an Ad5/35 vector expressing simian immunodeficiency virus (SIV) gag and gp120, and then boosting the animals with an modified vaccinia virus Ankara (MVA) vector encoding the same antigens after a 2-month interval. The animals were intravenously challenged with 100 TCID50 of highly pathogenic SIVmac239 virus 2 months after the booster vaccination. The priming vaccination induced robust SIV-specific cell-mediated and humoral immune responses, and boosting further enhanced the cellular immunity. Vaccination reduced peak and long-term viral loads by 1-2 logs for a period of >6 months, as reflected by a reduction in both the SIV RNA and DNA levels. Of considerable interest, the immunized monkeys did not suffer from loss of CD4 T cells, particularly central memory CD4 T cells. These results demonstrate that prophylactic vaccination with Ad5/35 followed by MVA reduces viral replication and prevents CD4 T-cell loss, and that these effects may decrease the likelihood of disease progression.
