Abstract
BACKGROUND The risk factors for coronavirus disease (COVID-19) among healthcare workers (HCWs) might have changed since the emergence of the highly immune evasive Omicron variant. AIM To compare the risk factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among HCWs during the Delta- and Omicron-predominant periods. METHODS Using data from repeated serosurveys among the staff of a medical research centre in Tokyo, two cohorts were established: Delta period cohort (N = 858) and Omicron period cohort (N = 652). The potential risk factors were assessed using a questionnaire. Acute/current or past SARS-CoV-2 infection was identified by polymerase chain reaction or anti-nucleocapsid antibody tests, respectively. Poisson regression was used to calculate the risk ratio (RR) of infection risk. FINDINGS The risk of SARS-CoV-2 infection during the early Omicron-predominant period was 3.4-fold higher than during the Delta-predominant period. Neither working in a COVID-19-related department nor having a higher degree of occupational exposure to SARS-CoV-2 was associated with an increased infection risk during both periods. During the Omicron-predominant period, infection risk was higher among those who spent ≥30 min in closed spaces, crowded spaces, and close-contact settings without wearing mask (≥3 times versus never: RR: 6.62; 95% confidence interval: 3.01-14.58), whereas no such association was found during the Delta period. CONCLUSION Occupational exposure to COVID-19-related work was not associated with the risk of SARS-CoV-2 infection in the Delta or Omicron period, whereas high-risk behaviours were associated with an increased infection risk during the Omicron period.

Abstract
BACKGROUND Muscle response in older adults is believed to decrease with maximal muscle strength, although it has not been adequately assessed; further, the relationship between frailty and muscle response remains unexamined. OBJECTIVES This study aimed to develop a practical method for measuring muscle response using grip strength in older adults and to clarify the relationship between frailty and grip strength response. DESIGN, SETTING, AND PARTICIPANTS We performed a cross-sectional, clinical, observational study. A total of 248 patients (94 men and 154 women, mean age: 78.2 years) who visited the outpatient unit in the Integrated Healthy Aging Clinic of our Hospital for the first time were enrolled. MEASUREMENTS Using a grip strength measuring device originally developed by us, we measured grip strength response indices, such as reaction time, time constant, rate of force development (response speed), and maximum grip strength. Grip strength response indices were compared among three groups (robust, pre-frail, and frail) according to the Fried and Kihon checklist assessments for frailty. RESULTS Based on Fried's assessment, marked differences were found between groups not only in maximal grip strength but also in response time and response speed. Based on the Kihon checklist assessment, there was no significant difference in response time; however, a considerable difference in response speed for the left hand was observed. Moreover, according to the Kihon checklist assessment, some cases showed differences in muscle response although not in maximal muscle strength. CONCLUSIONS The response speed of grip strength was suggested to decrease with frailty. The results suggest that measurement of grip strength response in both hands is useful to examine the relationship between frailty and grip strength response.

Abstract
Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown etiology that affects mostly young women. Multiorgan complications and prolonged treatment significantly cause physical and mental stress in patients. Improving patients’ quality of life (QOL) in SLE treatment is essential. We examined the treatment effects on disease activity and QOL of SLE patients.Objectives:In recent years, lupus low disease activity state (LLDAS) has been proposed as a treatment target for SLE. Patients who achieve LLDAS have a low recurrence rate for lupus and a low risk of serious complications (1). The aim of this study is to investigate whether achieving LLDAS reduces not only recurrence rate and complications of SLE but also improves patients’ QOL.Methods:A total of 104 SLE patients were enrolled in our prospective SLE registry study (Juntendo, Multi-center, Prospective cohort for investigation of clinical course and outcome in SLE: JUMP) conducted at our institution. SLE was diagnosed using the American College of Rheumatology (ACR) 1982 criteria (revised in 1997). QOL was evaluated using the standard version of the 36-item short form health survey version 2 (SF36v2). Participants were divided into the LLDAS achievement and non-achievement groups, and the characteristics of each group including results of SF36v2 were examined.Results:This study included 104 SLE patients, 94 female and 10 male, and the average age and disease duration were 46.4±13.8 and 14.5±11.3 years, respectively. The average corticosteroid dose was 8.0±17.4 mg/day in terms of prednisolone, and anti-dsDNA antibody titer was 16.8±38.5 IU/ml. Of the 104 patients, 57 achieved LLDAS. The subscale’s standard scoring using SF36v2 for role physical (RP) was 78.9±24.0 and 64.6±27.6 (P<0.01), general health (GH) was 50.0±17.0 and 42.0±19.3 (P<0.05), vitality (VT) was 55.8±15.8 and 38.0±24.1 (P<0.01), social functioning (SF) was 82.0±20.7 and 66.5±26.3 (P<0.01), role emotional (RE) was 89.0±16.1 and 73.4±28.1 (P<0.01), and mental health (MH) was 72.4±15.9 and 58.3±21.8 (P<0.01) in the LLDAS achievement and non-achievement groups, respectively. Furthermore, scoring based on the national standard value in the LLDAS achievement group showed that two categories were >50. However, in the LLDAS non-achievement group, all categories were <50. In particular, RP, GH, VT, SF, RE, and MH of the LLDAS achievement group had significantly higher scores than the LLDAS non-achievement group (RP and GH: p<0.05 and VT, SF, RE and MH: p<0.01).Conclusion:Results of examining the association between LLDAS and QOL using SF36v2 in SLE patients showed that patients who achieved LLDAS had significantly better standard statistical scores in many subscale categories. Thus, LLDAS achievement as a treatment target for SLE patients greatly contributes to improving patients’ QOL.References:[1]Franklyn K, et al.

Abstract
Abstract
Background
Previous studies demonstrated the impact of concomitant cancer on the increased risk of adverse cardiac and bleeding events after percutaneous coronary intervention (PCI). However, the impact in this 2nd- and 3rd-generation drug-eluting stent (DES) era remains to be elucidated.
Purpose
To clarify the impact of cancer on clinical outcomes in patients after 2nd- or 3rd -generation DES implantation.
Methods
A total of 932 patients who underwent PCI with 2nd- or 3rd -generation DES were included. Patients who were diagnosed with cancer after PCI were excluded from the present cohort. The incidence of major adverse cardiac events (MACE) including cardiac death, myocardial infarction and target or non-target vessel revascularization, and bleeding events was compared between the patients with cancer or the history of treatment for cancer (cancer group, n=140) and the patients without cancer (no cancer group, n=792). Bleeding events were evaluated according to the Thrombolysis in Myocardial Infarction definition. Further comparisons were performed between the 2 groups (cancer group, n=126; no cancer group, n=252) after the adjustment of baseline clinical characteristics using 1:2 propensity score-matching analysis.
Results
The incidence of MACE at median 577 [340–1043] days after the PCI was comparable between the 2 groups in both unadjusted (15.0% vs. 15.0%, p=0.984) (Panel A) and adjusted cohorts (14.3 vs. 13.1%, p=0.796), although the incidence of all cause death in the cancer group was significantly greater than the no cancer group (15.1 vs. 9.5%, p=0.007, in the adjusted cohort). The increased risk of MACE was not observed in any types of cancer or treatment (Panel B). The incidence of bleeding events was also comparable between the 2 groups (4.0 vs. 2.0%, p=0.297, in the adjusted cohort).
Conclusion
The increased incidence of MACE and bleeding events in patients with cancer was not demonstrated after the 2nd- or 3rd-generation DES implantation. Further studies are required to clarify the safety and efficacy of PCI in patients with cancer.

Abstract
Introduction
Syndecan-1 is a component of endothelial glycocalyx which maintains vascular integrity. Thus, it may be impaied in patients with coronary artery disease (CAD).
Purpose
To assess the association between serum syndecan-1 level and the severity and vulnerability of CAD.
Methods
A total of 259 consecutive patients with stable angina requiring percutaneous coronary intervention (PCI) were prospectively enrolled. Patients were classified into 2 groups according to the median syndecan-1 value (Lower syndecan-1 group [syndecan-1 <99.0], n=130; Higher syndecan-1 group [syndecan-1 ≥99.0], n=129). Severity of CAD and focal plaque vulnerability in target lesion was evaluated using findings of angiography and optical coherence tomography (OCT), respectively. Thin-cap fibroatheroma (TCFA) was defined as a lipid-rich plaque covered with thin fibrous cap (<65 μm).
Results
There was no significant difference in baseline clinical characteristics between the lower syndecan-1 group and the higher syndecan-1 group other than the prevalence of family history of ischemic heart disease (19 vs. 32%, p=0.022) and prior PCI history (45 vs. 60%, p=0.015). The prevalence of multivessel disease (70 vs. 68%, p=0.627), left main disease (4 vs. 5%, p=0.748) and chronic total occlusion (15 vs. 15%, p=0.959) was comparable between the 2 groups. On the other hand, the prevalence of lipid-rich plaque (40 vs. 19%, p=0.004) and TCFA (20 vs. 6%, p=0.006) was significantly higher in the lower syndecan-1 groupthan the higher syndecan-1 group (Figure). The lower syndecan-1 was independently associated with the higher prevalence of lipid-rich plaque (Table).
Table 1. Multivariate analysis for lipid-rich plaque Odds ratio 95% CI pvalue Lower syndecan-1 2.981 1.448–6.411 0.003 Dyslipidemia 1.693 0.738–4.142 0.218 Chronic kidney disease 1.354 0.669–2.765 0.400 Smoking 0.975 0.453–2.154 0.951 Diabetes mellitus 0.819 0.400–1.661 0.580
Conclusions
Lower syndecan-1 level was associated with higher prevalence of vulnerable plaque in patients with CAD. Serum syndecan-1 may have a potential as a marker for the presence of vulnerable coronary plaque.

Abstract
Abstract
Background
Among several parameters for stent expansion, which is better for predicting adverse events remains to be elucidated.
Purpose
To assess the predictive significance of several parameters for stent expansion on the incidence of adverse cardiac events.
Methods
A total of 183 consecutive patients with de novo lesion treated with drug-eluting stent (DES) under optical coherence tomography (OCT) guidance were enrolled. The stent expansion was retrospectively assessed on the final OCT images after the stent implantation by both conventional and novel parameters. The conventional parameters included the minimum stent cross-sectional area (MSA) and %stent expansion defined as [MSA/mean reference lumen cross-sectional area × 100]. The novel parameter was the minimum expansion index (MEI) calculated by using a novel algorhythm which yields the ideal lumen area in each frame by taking into account vessel tapering. The expansion index was calculated by [actual lumen area/ideal lumen area × 100] in each frame through the stented segment. The MEI was the minimum value of expansion index through the stented segment. The both conventional and novel parameters were compared between cases with and without device-oriented cardiac events (DoCE). Receiver operating characteristics (ROC) curves were constructed to assess the ability of those parameters to predict DoCE.
Results
The MSA and MEI in the DoCE group (n=12) were significantly smaller than the no DoCE group (n=171) (3.29±0.72 vs. 4.45±1.97 mm2, p<0.001, 66.9±10.6 vs. 78.3±14.8%, p=0.01, respectively), although the %stent expansion was not significantly different between the two groups (62.7±11.9 vs. 70.7±16.3%, p=0.094). In ROC analyses, the area under curve of MEI to predict DoCE was the largest among the parameters (Figure).
Conclusion
Among several parameters for stent expansion, a novel MEI was better to predict device-oriented cardiac events after DES implantation.

Abstract
BACKGROUND Intra-operative cell salvage is not routinely used during cesarean delivery because it is not cost-effective for patients at low risk of hemorrhage and there are theoretical concerns about amniotic fluid embolism. Some guidelines recommend using leukocyte depletion filters to decrease the risk of amniotic fluid embolism before re-infusing salvaged blood, but these filters are not available in Japan. We compared the efficacy and safety of leukocyte depletion and micro-aggregate filters in combination with intra-operative cell salvage during cesarean delivery. METHODS Blood was collected in a Cell Saver 5 reservoir during cesarean delivery. Four samples were collected: pre-wash, post-wash, post-filtration with a leukocyte depletion filter and post-filtration with a micro-aggregate filter. Each sample was analyzed for amniotic fluid markers of zinc coproporphyrin-1 and sialyl-Tn, for fetal hemoglobin, and the sample underwent pathological examination for white blood cells and squamous cells. Post-filtration samples were compared using paired t-tests with P <0.05 indicating statistical significance. RESULTS Zinc coproporphyrin-1 and sialyl-Tn were negative at almost all sample points. Squamous cells decreased by 59.1% post-wash and 91.2% post-filtration using a leukocyte depletion filter. Leukocyte depletion filters removed 99.7% of white blood cells and were more effective in removing white blood cells than micro-aggregate filters (P=0.02). CONCLUSION Leucocyte depletion filters are more effective in removing white blood cells and squamous cells than micro-aggregate filters, and their introduction for intra-operative cell salvage during cesarean delivery should be considered in Japanese clinical practice.

Abstract
The cyclopropylmethyl group in classical δ opioid receptor (DOR) antagonist NTI, BNTX, and NTB was replaced with various electron-withdrawing groups to develop DOR inverse agonists. N-Benzyl NTB derivative SYK-657 was a potent DOR full inverse agonist and its potency was over 10-fold potent than that of a reference compound ICI-174,864. Intraperitoneal administration of SYK-657 induced the short-term memory improving effect in mice without abnormal behaviors.

Abstract
Transwomen of color are disproportionately impacted by HIV and may have worse health outcomes than other populations. This analysis was conducted to examine structural factors associated with poor health outcomes among transwomen of color living with HIV in the San Francisco Bay Area (N = 159). Univariate and multivariable analyses were conducted to determine if structural factors were associated with poor HIV-related health outcomes. A majority of participants were Black or African American (110/159, 69.2%), 32 (20.1%) identified their primary race/ethnicity as Hispanic or Latino/a or Spanish, and 17 (10.7%) identified as another race/ethnicity. Transwomen of color in our sample faced extreme structural barriers, including residential transience, extreme low income, high prevalence of running out of money in the last six months, high rates of food insecurity, high prevalence of income via entitlement programs, engagement in sex work and other illicit activities for income. Unstable housing was the structural factor most consistently associated with poor health outcomes along the HIV care continuum and may explain engagement in other sources of income generation. Interventions are needed that go beyond the individual and health care-level to address needs for housing and economic opportunities to improve HIV care outcomes among transwomen of color living with HIV in the San Francisco Bay Area.

Abstract
Corticotrophin-releasing factor (CRF) regulates the hypothalamic-pituitary-adrenal axis response to stress through its type 1 receptor (CRF1 ) in the corticotrophs of the anterior pituitary. Although CRF1 mRNA expression has been confirmed in the rat pituitary, the distribution pattern of CRF1 protein in the pituitary has not been reported. Therefore, we generated an antiserum against the amino acid fragment corresponding to the 177-188 sequence of the first extracellular loop of the rat CRF1 . Using the antiserum, CRF1 -like immunoreactivity (CRF1 -LI) was detected in the anterior lobe cells of the rat pituitary where some of them expressed intense signals. CRF1 -LI also appeared in the intermediate lobe cells and on the fibre-like elements of the posterior lobe of the pituitary. Dual immunofluorescence labelling showed that corticotrophs exhibited the highest percentage of CRF1 (male: 27.1 ± 3.0%, female: 18.0 ± 3.0%), followed by lactotrophs (male: 6.7 ± 3.0%, female: 12.1 ± 1.3%), gonadotrophs (male: 2.6 ± 1.0%, female: 7.5 ± 0.5%), thyrotrophs (male: 2.9 ± 0.1%, female: 5.3 ± 1.2%) and somatotrophs (male: 1.1 ± 0.3%, female: 1.2 ± 0.5%). The percentage of CRF1 -LI-positive cells that were corticotrophs was significantly higher in male rats than in female rats, whereas CRF1 -LI-positive lactotrophs and gonadotrophs were significantly higher in female rats than in male rats. Almost all of the melanotrophs were positive for CRF1 in the intermediate lobe (98.9 ± 0.2%). CRF1 -LI and the percentage of CRF1 -LI in corticotrophs were decreased in the anterior pituitary, and the distribution patterns were altered from a diffuse to punctate one by adrenalectomy; the changes were restored by treatment with dexamethasone (100 μg/kg bw). These results suggest that CRF1 is involved in the modulation of the functions of the pituitary; moreover, protein expression and the distribution patterns of CRF1 are regulated by glucocorticoids in the rat anterior pituitary.

Abstract
AbstractBackgroundThe mode of onset and the course of schizophrenia illness exhibit substantial individual variations. Previous studies have pointed out that the mode of onset affects the duration of untreated psychosis (DUP) and clinical outcomes, such as cognitive and social functioning. This study attempted to clarify the association between the DUP and clinical features, taking the different modes of onset into consideration, in a prospective longitudinal study examining patients with first-episode schizophrenia.MethodsThis study was conducted in six areas of Japan. Patients with first-episode schizophrenia were followed for over 18 months. Cognitive function, psychopathology, and social functioning were assessed at baseline and at 6, 12, and 18-month follow-up points.ResultsWe identified 168 patients and sufficient information was available to determine the DUP and the mode of onset for 156 patients (92.9%): 79 had an acute onset, and 77 had an insidious onset. The DUP was significantly associated with quality of life (QOL), social functioning, and cognitive function at most of the follow-up points in the insidious-onset group. The DUP and negative symptoms at baseline were significant predictors of cognitive function at the 18-month follow-up in the insidious-onset group.ConclusionsThe present results further support the hypothesis that the DUP affects QOL, social functioning, and cognitive function over the course of illness, especially in patients with an insidious onset. Effective strategies for detecting and caring for individuals with insidious onset early during the course of schizophrenia will be essential for achieving a full patient recovery.

Abstract
BACKGROUND AND PURPOSE Activation of δ opioid (DOP) receptors regulates pain and emotional responses, and also displays ligand-biased agonism. KNT-127 (1,2,3,4,4a,5,12,12a-octahydro-2-methyl-4aβ,1β-([1,2]benzenomethano)-2,6-diazanaphthacene-12aβ,17-diol) is a novel DOP receptor agonist inducing analgesia and antidepressant effects in mice. Here, we have assessed KNT-127 for (i) analgesia against chronic inflammatory pain; (ii) effects on depression, locomotion and DOP receptor internalization; and (iii) for cross-tolerance to analgesic and antidepressant effects of acute treatment by other DOP receptor agonists. EXPERIMENTAL APPROACH Inflammatory pain was induced by complete Freund's adjuvant injection into tail or hindpaw, and thermal and mechanical sensitivities were determined in mice. Locomotor and antidepressant-like effects were measured using actimetry and forced swim test respectively. In vivo KNT-127 selectivity and internalization were assessed using DOP receptor knockout mice and knock-in mice expressing fluorescent-tagged DOP receptors. KNT-127 was injected acutely at 0.1-10.0 mg·kg(-1) or administered chronically at 5 mg·kg(-1) daily over 5 days. KEY RESULTS Acute treatment with KNT-127 reversed inflammatory hyperalgesia, produced an antidepressant-like effect but induced neither hyperlocomotion nor receptor sequestration. Chronic treatment with KNT-127 induced tolerance and cross-tolerance to SNC80-induced analgesia, but no tolerance to SNC80-evoked hyperlocomotor or antidepressant-like effects. CONCLUSIONS AND IMPLICATIONS The DOP receptor agonist KNT-127 induced agonist-specific acute and chronic responses, at both behavioural and cellular levels. It displays activities similar to the other recently reported DOP agonists, AR-M1000390, ADL5747 and ADL5859, and differs from SNC80. SNC80 differs from the other DOP receptor agonists including KNT-127, by exhibiting ligand-biased tolerance at this receptor.

Abstract
Transgender women - individuals assigned a male sex at birth who identify as women, female, or on the male-to-female trans feminine spectrum - are at high-risk of HIV worldwide. Prior research has suggested that transgender women more frequently engage in condomless sex with primary cisgender (i.e., non-transgender) male partners compared with casual or paying partners, and that condomless sex in this context might be motivated by relationship dynamics such as trust and intimacy. The current study examined sexual agreement types and motivations as factors that shape HIV risk behaviors in a community sample of 191 transgender women and their cisgender primary male partners who completed a cross-sectional survey. Overall, 40% of couples had monogamous, 15% open, and 45% discrepant sexual agreements (i.e., partners disagreed on their type of agreement). Actor-partner interdependence models were fit to examine the influence of sexual agreement type and motivations on extra-dyadic HIV risk (i.e., condomless sex with outside partners) and intra-dyadic HIV serodiscordant risk (i.e., condomless sex with serodiscordant primary partners). For male partners, extra-dyadic risk was associated with their own and their partners' sexual agreement motives, and male partners who engaged in extra-dyadic HIV risk had an increased odds of engaging in HIV serodiscordant intra-dyadic risk. Study findings support inclusion of the male partners of transgender women into HIV prevention efforts. Future research is warranted to explore the interpersonal and social contexts of sexual agreement types and motivations in relationships between transgender women and their male partners to develop interventions that meet their unique HIV prevention needs.

Abstract
We designed and synthesized the 1,3,5-trioxazatriquinane derivatives with m-hydroxyphenyl groups. These compounds include the phenethylamine structure within them, which is a common structure observed in morphinan derivatives like morphine. Among the synthesized compounds, (-)-8c with two m-hydroxyphenyl groups selectively bound and exerted full agonist activity toward the κ opioid receptor (KOR). Subcutaneously administered (-)-8c exhibited significant antinociceptive effects via the KOR in a dose-dependent manner. These results suggest the emergence of a novel class of KOR agonist.

Abstract
We synthesized compounds 4a,c-f,h,i containing the oxazatricyclodecane structure from a novel rearrangement reaction product 2a. All the prepared compounds 4a,c-f,h,i exhibited full agonistic activities for the δ opioid receptor (DOR). Among them, the N-methyl derivative 4c was highly selective, and the most effective DOR agonist in functional assays. Subcutaneous administration of 4c produced dose-dependent and NTI (selective DOR antagonist)-reversible antinociception lacking any convulsive behaviors in the mice acetic acid writhing tests. The N-methyl derivative 4c is expected to be a promising lead compound for selective DOR agonists with a novel chemotype.

Abstract
BACKGROUND We developed a new grip strength measuring device, which considers the time axis, for evaluating muscle contraction in detail in elderly people. OBJECTIVES To present the novel device and preliminary results concerning agility in gripping. DESIGN Cross-sectional analysis. PARTICIPANTS One hundred and twenty-one older persons (48 men and 73 women, mean age 74.4 years) referring for memory disorders to the outpatient clinic of our institute. MEASUREMENTS A novel device taking advantage of an industrial force-gauge was developed for measuring gripping performance. The instrument graphically described participants' strength production. Nine indices were derived from four points identified by the graph: 1) starting point ("Go signal"), 2) time when gripping starts, 3) turning point (TP) when the inclination of the curve depicting strength production changes, and 4) peak of strength production. Results obtained from the study sample of older persons were compared (as ratios) to a control group of 30 healthy young adults in their thirties in order to calculate age-related decline rates. Differences between right and left side were compared. RESULTS A significant difference was observed between right and left hands concerning the time to reach peak of strength, and time from TP to strength peak in both men and women. For women, the following indices were also significantly different: time to reach TP, strength at TP, time from TP to strength peak, curve inclination from TP to strength peak, and ratio of TP strength divided by peak strength. CONCLUSION Declines in several indices of gripping agility were measured. The parameters which were more closely related to time than strength itself showed significant differences between right and left hands, especially in women.

Abstract
We investigated the structure-activity relationship of KNT-127 (opioid δ agonist) derivatives with various 17-substituents which are different in length and size. The 17-substituent in KNT-127 derivatives exerted a great influence on the affinity and agonistic activity for the δ receptor. While the compounds with electron-donating 17-substituents showed higher affinities for the δ receptor than those with electron-withdrawing groups, KNT-127 derivatives with 17-fluoroalkyl groups (the high electron-withdrawing groups) showed high selectivities for the δ receptor among evaluated compounds. In addition, the basicity of nitrogen as well as the structure of the 17-N substituent such as the length and configuration at an asymmetric carbon atom contributed to agonist properties for the δ receptor. Thus, the analog with a 17-(3-ethoxypropyl) group showed the best selectively and potent agonistic activity for the δ receptor among KNT-127 derivatives. These findings should be useful for designing novel δ selective agonists.

Abstract
On the basis of the three-dimensional pharmacophore model of opioid κ agonists, we simplified the structure of nalfurafine (selective κ agonist) to find the essential structural moieties for binding the opioid receptors, especially κ receptor type. As a result, we found that the trans-fused decahydroisoquinoline derivatives without a phenol ring bound the opioid receptor in micromolar order and that both the amide side chain and the nitrogen substituted by the cyclopropylmethyl group were indispensable moieties for eliciting the κ selectivity. The simple decahydroisoquinoline without amide side chain also bound the opioid receptor without receptor type selectivity, suggesting that the message-address concept would be applicable to even these simple derivatives. These findings that the simple decahydroisoquinoline derivatives showed the affinities for the opioid receptors, especially some of the compounds showed κ selectivity, are the first example in the opioid field.

Abstract
Novel double-capped triplet drugs, which have one pharmacophore unit and two epoxymethano or dimethylepoxymethano structures (termed cap or diMe-cap structures, respectively) were synthesized. Key intermediate oxazoline 16 derived from acetone enabled the effective synthesis of double-capped triplets. SYK-134 (7a) and SYK-135 (8a) with N-cyclopropylmethyl substituent and cap structures showed selectivities for the κ opioid receptor. On the other hand, the N-Me series exhibited selectivities for the μ opioid receptor. The double-capped triplet drugs with diMe-cap structures preferred the μ receptor independently of their N-substituents. SYK-385 (19b), one of the μ-selective double-capped triplet drugs, showed the highest selectivity for the μ receptor among the reported μ-selective nonpeptide ligands.

Abstract
To clarify the essential structures of an opioid κ receptor selective agonist, nalfurafine, for binding to the κ receptor, we designed and synthesized the decahydro(iminoethano)phenanthrene derivatives with an oxygen functionality at the 3-position. The introduction of a hydroxy group to the derivatives increased the affinity and selectivity to the κ receptor regardless of the configuration at the 3-position. However, their affinities were lower than those of nalfurafine with the phenolic hydroxy group. The results suggested that the acidity of the hydroxy group would play an important role in the interaction with the opioid receptor. The low affinities of the 3-keto derivatives indicated that the 3-hydroxy group may participate in the hydrogen bonding with the receptor site not as a hydrogen acceptor but as a hydrogen donor. This is the first experimental evidence for a role as a hydrogen donor for the 3-hydroxy group in morphinans. Furthermore, the κ selectivities in these derivatives with the 6α-amide side chain were affected by the the 3-hydroxy group. The obtained structure-activity relationship information is expected to be useful for the design of more selective ligands for the κ receptor.

Abstract
Early intervention for psychosis in Japan has lagged behind that in western countries, but has rapidly begun to attract attention in recent years. As part of a worldwide trend, a multi-dimensional treatment centre for early psychosis consisting of a Youth Clinic, which specialises in young individuals with an at-risk mental state for psychosis, and Il Bosco, a special day-care service for individuals with early psychosis, was initiated at the Toho University Omori Medical Center in Japan in 2007. The treatment centre aims to provide early intervention to prevent the development of full-blown psychosis in patients with an at-risk mental state and intensive rehabilitation to enable first-episode schizophrenia patients to return to the community. We presently provide the same programmes for both groups at Il Bosco. However, different approaches may need to be considered for patients with an at-risk mental state and for those with first-episode schizophrenia. More phase-specific and need-specific services will be indispensable for early psychiatric interventions in the future.

Abstract
We previously reported that the δ opioid receptor (DOP) agonists SNC80 and TAN-67 produce potent antidepressant-like and antinociceptive effects in rodents. However, SNC80 produced convulsive effects. Recently, we succeeded in synthesizing a novel DOP agonist called KNT-127. The present study examined the convulsive, antidepressant-like, and antinociceptive effects of KNT-127 in mice. In contrast to SNC80, KNT-127 produced no convulsions at doses of up to 100mg/kg. In mice subjected to the forced swim test, a screening model for antidepressants, KNT-127 (1mg/kg, s.c.) significantly decreased the duration of immobility and increased the duration of swimming without influencing spontaneous locomotor activity. These behavioral changes were similar to that observed for the tricyclic antidepressant imipramine (6mg/kg). The antidepressant-like effect of KNT-127 in mice was antagonized by pretreatment with naltrindole (NTI), a selective DOP antagonist, or naltriben, a putative DOP(2) subtype antagonist. In addition, KNT-127 (3mg/kg, s.c.) significantly reduced the number of acetic acid-induced abdominal constrictions and the duration of licking time, respectively, in mice subjected to a writhing test and a formalin test. These antinociceptive effects were antagonized by pretreatment with either NTI or 7-benzylidenenaltrexone, a putative DOP(1) subtype antagonist. We propose that KNT-127 should be considered as a candidate compound for the development of DOP-based antidepressants and/or analgesics that lack convulsive effects.

Abstract
Excessive mechanical stress (MS) during hyperocclusion is known to result in disappearance of the alveolar hard line, enlargement of the periodontal ligament (PDL) space, and destruction of alveolar bone, leading to occlusal traumatism. We hypothesized that MS induces expression of osteoclastogenesis-associated chemokines in PDL tissue, resulting in chemotaxis and osteoclastogenesis during occlusal traumatism. We examined the effect of MS on relationships between chemokine expression and osteoclastogenesis using in vivo and in vitro hyperocclusion models. In an in vitro model, intermittent stretching-induced MS was shown to up-regulate the expression of CC chemokine ligand (CCL)2, CCL3, and CCL5 in PDL cells. The expression levels of CCL2 in PDL tissues, its receptor CCR2 in pre-osteoclasts, and tartrate-resistant acid-phosphatase-positive cells in alveolar bone were significantly up-regulated 4-7 days after excessive MS during hyperocclusion in in vivo rodent models. Hyperocclusion predominantly induced CCL2 expression in PDL tissues and promoted chemotaxis and osteoclastogenesis, leading to MS-dependent alveolar bone destruction during occlusal traumatism.

Abstract
The chemotherapy regimen currently used for treating esophageal and gastric carcinoma has been either epirubicin, cisplatin, and fluorouracil (5-FU) or docetaxel, cisplatin, and 5-FU. Here, we report the efficacy and toxicity of doxorubicin, cisplatin, and 5-FU for only esophageal squamous cell carcinoma (ESCC). Between January 2000 and October 2008, a total of 41 ESCC patients with a distant metastasis were enrolled. The most common sites of metastasis were liver (26, 63.4%), lung (9, 22.0%), and bone (8, 19.5%). Doxorubicin was administered on day 1 at 30 mg/m(2) , cisplatin on days 1-5 at 14 mg/m(2)/day, and 5-FU on days 1-5 at 700 mg/m(2)/day. The median number of cycles was 2.0 (range 1-8). The dose intensities of doxorubicin, cisplatin, and 5-FU were 92.9, 92.4, and 92.5%, respectively. The overall response rate was 43.9%; one showed complete response, 17 showed partial response, 13 showed a stable disease, and 10 showed progressive disease (PD). The median survival time was 306 days (95% CI = 74-935) and the 1-year survival rate was 37.6%. Grade 3 neutropenia was seen in seven patients and grade 4 in one patient. Grade 3 fatigue, anorexia, mucositis, and diarrhea were observed in three, two, two, and one patient, respectively. This regimen is effective as a first-line therapy for ESCC with distant metastasis.

Abstract
To explore the social context of drug use and sexual behaviours that put male-to-female (MTF) transgenders at risk for HIV, focus groups were conducted consisting of African American, Latina and Asian and Pacific Islander MTF transgenders (N = 48) who reside or work in San Francisco, California. Participants were likely to report having unprotected sex with primary partners to signify love and emotional connection, as well as to receive gender validation from their partners. In contrast, viewing sex work with customers as a business encouraged intentious to use condoms. Safer sex intentions with customers were frequently undermined by urgent financial needs, which stemmed from transphobia, employment discrimination and costly procedures associated with gender transition. Participants reported using drugs as a way to cope with or escape life stresses associated with relationships, sex work, transphobia and financial hardship. Interventions with at-risk MTF transgenders should address the interpersonal and social context of unsafe sex and drug use, particularly the unique roles of relationship issues with male partners, stigma, discrimination and community norms regarding sex work and drug use.
