Abstract
BACKGROUND The comparative effectiveness study (ClinicalTrials.gov, NCT03016403) assessed the effects of a stepped-care intervention versus usual care on mental health outcomes, including anxiety, depression, coping self-efficacy, emotional distress (anxiety and depression combined), health-related quality of life (HRQoL), and perceived stress among underserved patients (i.e., low-income, uninsured, underinsured) with lung cancer (LC) and head-and-neck cancer (HNC). METHODS In a randomized controlled trial, we investigated if 147 patients who received the stepped-care intervention had better mental health outcomes compared to 139 patients who received usual care. Using an intent-to-treat approach, we analyzed outcomes with linear mixed models. RESULTS For the primary outcomes estimated mean differences (denoted by "Δ"), depression (Δ = 1.75, 95% CI = 0.52, 2.98, p = 0.01) and coping self-efficacy (Δ = -15.24, 95% CI = -26.12, -4.36, p = 0.01) were better for patients who received the intervention compared to patients who received usual care, but anxiety outcomes were not different. For secondary outcomes, emotional distress (Δ = 1.97, 95% CI: 0.68, 3.54, p =< 0.01) and HRQoL (Δ = -4.16 95% CI: -7.45, -0.87, p = 0.01) were better for patients who received the intervention compared to usual care patients, while perceived stress was not different across groups. CONCLUSIONS The stepped-care intervention influenced depression and coping self-efficacy, important outcomes for patients with acute illnesses like LC and HNC. Although differences in emotional distress met the minimally important differences (MID) previously reported, depression and HRQoL were not above the MID threshold. Our study is among a few to report differences in mental health outcomes for underserved LC and HNC patients after receiving a psychological intervention. CLINICALTRIALS GOV IDENTIFIER NCT03016403.

Abstract
PURPOSE Screening with mammography and breast magnetic resonance imaging (MRI) is an important risk management strategy for individuals with inherited pathogenic variants (PVs) in genes associated with increased breast cancer risk. We describe longitudinal screening adherence in individuals who underwent cancer genetic testing as part of usual care in a vertically integrated health system. METHODS We determined the proportion time covered (PTC) by annual mammography and breast MRI for individuals with PVs in TP53, BRCA1, BRCA2, PALB2, NF1, CHEK2, and ATM. We determined time covered by biennial mammography beginning at age 50 years for individuals who received negative results, uncertain results, or with PVs in genes without specific breast cancer screening recommendations. RESULTS One hundred and forty individuals had PVs in TP53, BRCA1, BRCA2, PALB2, NF1, CHEK2, or ATM. Among these individuals, average PTC was 48% (range 0-99%) for annual screening mammography and 34% (range 0-100%) for annual breast MRI. Average PTC was highest for individuals with PVs in CHEK2 (N = 14) and lowest for individuals with PVs in TP53 (N = 3). Average PTC for biennial mammography (N = 1,027) was 49% (0-100%). CONCLUSION Longitudinal screening adherence in individuals with PVs in breast cancer associated genes, as measured by the proportion of time covered, is low; adherence to annual breast MRI falls below that of annual mammography. Additional research should examine screening behavior in individuals with PVs in breast cancer associated genes with a goal of developing interventions to improve adherence to recommended risk management.

Abstract
BACKGROUND Genetic testing can identify cancer risk early, enabling prevention and early detection. We describe use of risk management interventions following genetic testing in the Cancer Health Assessment Reaching Many (CHARM) study. CHARM assessed risk and provided genetic testing to low income, low literacy, and other underserved populations that historically face barriers to accessing cancer genetic services. METHODS CHARM was implemented in Kaiser Permanente Northwest (KPNW) and Denver Health (DH) between 2018 and 2020. We identified post-testing screening (mammography, breast MRI, colonoscopy) and surgical (mastectomy, oophorectomy) procedures using electronic health records. We examined utilization in participants who did and did not receive actionable risk management recommendations from study genetic counselors following national guidelines. RESULTS CHARM participants were followed for an average of 15.4 months (range: 0.4-27.8 months) after results disclosure. Less than 2% (11/680) received actionable risk management recommendations (i.e., could be completed in the initial years following testing) based on their test result. Among those who received actionable recommendations, risk management utilization was moderate (54.5%, 6/11 completed any procedure) and varied by procedure (mammogram: 0/3; MRI: 2/4; colonoscopy: 4/5; mastectomy: 1/5; oophorectomy: 0/3). Cancer screening and surgery procedures were rare in participants without actionable recommendations. CONCLUSION Though the number of participants who received actionable risk management recommendations was small, our results suggest that implementing CHARM's risk assessment and testing model increased access to evidence-based genetic services and provided opportunities for patients to engage in recommended preventive care, without encouraging risk management overuse.

Abstract
Underserved patients face substantial barriers to receiving cancer genetic services. The Cancer Health Assessments Reaching Many (CHARM) study evaluated ways to increase access to genetic testing for individuals in underserved populations at risk for hereditary cancer syndromes (HCS). Here, we report the successful implementation of CHARM in a low-resource environment and the development of sustainable processes to continue genetic risk assessment in this setting. The research team involved key clinical personnel and patient advisors at Denver Health to provide input on study methods and materials. Through iterative and collaborative stakeholder engagement, the team identified barriers and developed solutions that would both facilitate participation in CHARM and be feasible to implement and sustain long term in clinical care. With a focus on infrastructure building, educational modules were developed to increase awareness among referring providers, and standard methods of identifying and managing HCS patients were implemented in the electronic medical record. Three hundred sixty-four DH patients successfully completed the risk assessment tool within the study, and we observed a sustained increase in referrals to genetics for HCS (from 179 in 2017 to 427 in 2021 post-intervention). Implementation of the CHARM study at a low-resourced safety net health system resulted in sustainable improvements in access to cancer genetic risk assessment and services that continue even after the study ended.Trial registration NCT03426878.

Abstract
BACKGROUND Germline genetic testing enables primary cancer prevention, including through prophylactic surgery. We examined risk-reducing surgeries in unaffected individuals tested for hereditary cancer susceptibly between 2010 and 2018 in the Kaiser Permanente Northwest health system. METHODS We used an internal genetic testing database to create a cohort of individuals who received tests including one or more high-penetrance hereditary cancer susceptibility gene. We then identified, after testing, bilateral mastectomy, bilateral salpingo-oophorectomy (BSO), and total hysterectomy procedures in electronic health record and claims data through 2019. We describe surgery utilization by genetic test results and National Comprehensive Cancer Network (NCCN) guidelines. RESULTS The cohort included 1020 individuals, 16% with pathogenic/likely pathogenic (P/LP) variants in one or more of the following genes: BRCA1, BRCA2, CHEK2, APC, MUTYH, ATM, MSH2, PALB2, BRIP1, MLH1, MSH6, EPCAM, FLCN, RAD51C, RAD51D, or TP53. Among individuals with P/LP variants making them candidates for mastectomy, BSO, or hysterectomy per NCCN guidelines, 34% (33/97), 24% (23/94), and 8% (1/12), respectively, underwent surgery during follow-up. Fifty-three percent (18/37) of hysterectomies were among APC, BRCA1, and BRCA2 P/LP variant heterozygotes, typically concurrent with BSO. Three individuals with variants of uncertain significance (only) and 22 with negative results had prophylactic surgery after genetic testing. CONCLUSIONS Uptake of risk-reducing surgery following usual care genetic testing appears to be lower than in studies that actively recruit high-risk patients and provide testing and follow-up care in specialized settings. Factors in addition to genetic test results and NCCN guidelines motivate prophylactic surgery use and deserve further study.

Abstract
PURPOSE This study aimed to evaluate the laboratory-related outcomes of participants who were offered genomic testing based on cancer family history risk assessment tools. METHODS Patients from clinics that serve populations with access barriers, who are screened at risk for a hereditary cancer syndrome based on adapted family history collection tools (the Breast Cancer Genetics Referral Screening Tool and PREMM5), were offered exome-based panel testing for cancer risk and medically actionable secondary findings. We used descriptive statistics, electronic health record review, and inferential statistics to explore participant characteristics and results, consultations and actions related to pathogenic/likely pathogenic variants identified, and variables predicting category of findings, respectively. RESULTS Of all the participants, 87% successfully returned a saliva kit. Overall, 5% had a pathogenic/likely pathogenic cancer risk variant and 1% had a secondary finding. Almost all (14/15, 93%) participants completed recommended consultations with nongenetics providers after an average of 17 months. The recommended actions (eg, breast magnetic resonance imaging) were completed by 17 of 25 participants. Participant personal history of cancer and PREMM5 score were each associated with the category of findings (history and colon cancer finding, Fisher's exact P = .02; history and breast cancer finding, Fisher's exact P = .01; PREMM5TM score; and colon cancer finding, Fisher's exact P < .001). CONCLUSION This accessible model of hereditary cancer risk assessment and genetic testing yielded results that were often acted upon by patients and physicians.

Abstract
Advances in the application of genomic technologies in clinical care have the potential to increase existing healthcare disparities. Studies have consistently shown that only a fraction of eligible patients with a family history of cancer receive recommended cancer genetic counseling and subsequent genetic testing. Care delivery models using pre-test and post-test counseling are not scalable, which contributes to barriers in accessing genetics services. These barriers are even more pronounced for patients in historically underserved populations. We have designed a multimodal intervention to improve subsequent cancer surveillance, by improving the identification of patients at risk for familial cancer syndromes, reducing barriers to genetic counseling/testing, and increasing patient understanding of complex genetic results. We are evaluating this intervention in two large, integrated healthcare systems that serve diverse patient populations (NCT03426878). The primary outcome is the number of diagnostic (hereditary cancer syndrome) findings. We are examining the clinical and personal utility of streamlined pathways to genetic testing using electronic medical record data, surveys, and qualitative interviews. We will assess downstream care utilization of individuals receiving usual clinical care vs. genetic testing through the study. We will evaluate the impacts of a literacy-focused genetic counseling approach versus usual care genetic counseling on care utilization and participant understanding, satisfaction, and family communication. By recruiting participants belonging to historically underserved populations, this study is uniquely positioned to evaluate the potential of a novel genetics care delivery program to reduce care disparities.

Abstract
Abstract
Introduction: The Cancer Health Risk Assessments Reaching Many (CHARM) study (NCT03426878) aims to increase access to genetic testing for hereditary cancer in low-income, low-literacy, and minority populations (hereafter referred to as “underserved”). To implement the study, we have capitalized on the availability of electronic medical record (EMR) systems, developed innovative web-based tools, and designed a novel telemedicine protocol for return of clinical genetic testing results.
Methods: Patients aged 18-49 years are recruited from two centers: Kaiser Permanente Northwest (KPNW; an integrated health care system in Portland, OR) and Denver Health (DH; a federally qualified health care center in Denver, CO). Specific protocols were developed to identify potentially eligible patients from the EMR and invite them to complete a web-based family history assessment. KPNW patients were recruited using email, text messaging, and in-clinic booths; DH patients were recruited via mail, phone, and provider referral. Validated risk assessment tools for Lynch syndrome (PREMM5) and heredity breast and ovarian cancer syndrome (B-RST) were adapted for our low-literacy and bilingual (English and Spanish) target population. Genetic testing is offered to patients with greater than average risk for hereditary cancer, or where risk cannot be assessed because of unknown family history or limited family structure. Eligible patients review a multipart, multimedia online consent. Those who consent to participate provide a saliva sample for clinical exome sequencing. Genetic counselors return results by telephone using traditional (usual care active comparator) or modified, communication-focused (experimental) counseling for pathogenic variants, likely pathogenic variants, and select variants of uncertain significance in 39 genes related to cancer risk, pathogenic variants in 79 genes related to medically actionable secondary findings, and 14 genes related to carrier status.
Results: In the first four months of recruitment, 258 patients have completed the risk assessment tool (48% are underserved). Of those, 180 (70%) had greater than average risk of hereditary cancer (or limited family history information) and were invited to participate (53% were underserved); 86% of underserved patients and 78% of patients who do not meet criteria for the underserved category have consented. The vast majority of participants complete enrollment without assistance from study staff, and in-person visits are not required for participation. Telephone genetic test result disclosure will begin in December 2018.
Conclusions: We have successfully developed online tools for cancer risk assessment that are accessible to underserved and low-literacy populations. These tools may be a cost-effective approach for improving the capture of family history data in the EMR. It does not require a provider to gather the information and the patient gets immediate feedback on results of the risk assessment and appropriate next steps.

Abstract
OBJECTIVES Dementia, which is characterized by a progressive decline in cognitive function, is a major concern in aging societies. Although a number of treatments have been approved, an effective therapy to prevent the disorder is lacking. A supplement that improves cognitive function would benefit patients. The aim of this study was to assess whether auraptene, a citrus coumarin, has a protective effect on cognitive decline. DESIGN A randomized, placebo-controlled, double-blind study SETTING: Outpatient medical check-up program for cognitive disorders PARTICIPANTS: 84 adult volunteers (they are cognitively normal) met inclusion and exclusion criteria to participate. INTERVENTION 42 participants received auraptene enriched (containing 6.0 mg/day of auraptene) test juice, and another participants received placebo juice. MEASUREMENTS 1) Mild Cognitive Impairment (MCI) Screen using the 10-word immediate recall test. 2) The Mini-Mental State Examination (MMSE). Cognitive assessment ware carried out baseline and at 24 weeks. RESULTS Auraptene enriched test juice did not improve cognitive function after 24 weeks compared with baseline data. However, there was a significant difference in the percentage change in cognitive function between the test and placebo orange juice groups (6.3 ± 18.9 vs. -2.4 ± 14.8, P < 0.05). Multiple regression analysis demonstrated a significant independent relationship between the percentage change in the 10-word immediate recall test score and test juice consumption including baseline 10-word immediate recall test score in all subjects. CONCLUSION This is the first study to assess the effectiveness of auraptene in the prevention of cognitive decline. Our results suggest that auraptene is a safe supplement for the prevention of cognitive decline.

Abstract
Background: We present and describe tailored strategies to address known barriers to minority participation in clinical trial research. The strategies used allowed our team to engage communities and successfully recruit, enroll, and retain a diverse underserved population of Latinos with advanced cancer for this clinical trial. Methods: Participants were recruited from 3 urban and 7 rural sites. We identified 4 critical barriers to recruitment for this underserved population: (1) mistrust; (2) language and communication barriers; (3) lack of access to academic cancer center; and (4) inability to participate due to transportation, childcare, or work responsibilities. We developed tailored strategies to engage referring sites and patients to participate in the clinical trial. Results: We identified 318 potentially eligible participants; 34 were found to be ineligible, and 223 consented to participate in the study, representing a 79.0% enrollment rate. All patients (100%) self-identified as Latino, and 47.5% spoke Spanish as their primary language. Patients were socioeconomically disadvantaged: 53.6% had an annual income <$15,000 USD, and 50.2% had less than a high school education. A total of 177 participants completed the 3-month follow-up; 26 died before the 3-month follow interview, and 20 did not complete the follow-up evaluation (9% withdrawal rate). Conclusions: Our community-informed strategies were highly effective for recruiting, enrolling, and retaining an underserved diverse population of Latinos. The barriers we identified and the strategies we used have the potential to inform research to increase minority participation in cancer clinical trials. ClinicalTrials.gov identifier: NCT01695382.

Abstract
Eculizumab is a novel monoclonal antibody that inhibits complement-mediated hemolysis in patients with paroxysmal nocturnal hemoglobinuria (PNH). Complement deficiency is a well-known risk factor for meningococcal infection. We describe a case of a young patient with PNH treated with eculizumab who presented with a life-threatening case of nongroupable meningococcemia. As this new biologic agent becomes more widely prescribed, providers should be aware of the increased risk of meningococcemia. In addition to vaccination, providers may consider the use of oral penicillin for antibiotic prophylaxis against Neisseria meningitidis in these cases of functional complement deficiency.

Abstract
This paper examines predictors of cancer-specific distress among posttreatment adult leukemia and lymphoma survivors (LLS). Using a survey mailed to LLS in the Colorado Central Cancer Registry (N = 477), the authors developed a multivariable risk profile for distress. Thirty one percent of LLS reported indicators of distress. Significantly higher distress was associated with younger age (p < 0.001) in bivariate analyses. The risk profile included fear of recurrence, financial burden, and younger age. Distress did not attenuate based on time since treatment completion and may persist up to 4 years posttreatment, suggesting a need for intervention, particularly among high-risk LLS.

Abstract
Using in-depth interviews, this paper explores the nature and sources of cancer-specific distress among 51 posttreatment adult leukemia and lymphoma survivors (LLS), focusing on the role of lifespan stage in shaping reported stressors. LLS (all ages) reported physical aftereffects of cancer treatment, with reported sources of emotional and financial distress varying by lifespan stage. Young adult survivors (18-39) reported a greater number of distress sources. Distress may persist up to 4 years posttreatment, particularly among younger LLS, who appear to be at greater risk of distress in multiple domains.

Abstract
OBJECTIVE Over one third of patients with cancer experience elevated psychosocial distress. As screening for distress becomes more common, the number of patients referred for psychosocial care will increase. Psychosocial telephone interventions are recommended as a convenient and exportable alternative to in-person interventions addressing psychosocial distress. This study reviews the efficacy of randomized controlled trials (RCTs) of psychosocial telephone interventions for patients with cancer. METHODS We conducted a systematic review of peer-reviewed RCTs evaluating telephone interventions in adult patients with cancer across the survivorship continuum. RESULTS Through a database search, 480 articles were identified. After manual review, 13 were included, with 7 additional studies identified by back citation, totaling 20 studies. Participants were largely Caucasian, highly educated, with mean age ranging from 49 to 75 years. Most participants were patients with breast cancer (n = 13 studies). Sample sizes were generally small, with most patients recruited from large medical centers. Only one screened for psychosocial need. Interventions varied greatly in length and intensity. Eight studies reported significant effects post-intervention in the hypothesized direction on at least one psychosocial outcome measure. Of these eight studies, four included more than one follow-up assessment; of these, only one reported significant effects at last follow-up. No clear commonalities were found among studies reporting significant effects. CONCLUSIONS Methodological concerns and lack of consistency in adherence to CONSORT reporting guidelines were identified. This body of research would benefit from well-designed, theory-based RCTs adequately powered to provide more definitive evidence for intervention efficacy. This will probably require multi-institutional collaborations, guided by intervention and research methodology best practices.

Abstract
OBJECTIVE To develop a feasibility study of a theory-driven telephone counseling program to enhance psychosocial and physical well-being for cancer survivors after treatment. METHODS Participants (n=66) were recruited from two Colorado hospitals with self-administered questionnaires at baseline and two weeks post-intervention. The one group, intervention only design included up to six thematic telephone counseling sessions over three months. Topics included nutrition, physical activity, stress management, and medical follow-up. Primary outcomes were cancer-specific distress, self-reported fruit and vegetable consumption and physical activity. RESULTS Of 66 subjects, 46 completed at least one counseling module and the follow-up assessment (70% retention rate). Mean satisfaction was 9 out of 10, and all participants would recommend C-STEPS to other survivors. Cancer-specific distress (Impact of Event Scale - Intrusion subscale) decreased for entire study population (p<0.001) and stress management session participants (p<0.001). Fruit and vegetable consumption increased for nutrition and exercise session participants (p=0.02) and the entire sample (p=NS). Physical activity increased in the entire group (p=0.006) and for nutrition and exercise session participants (p=0.01). CONCLUSION AND PRACTICE IMPLICATIONS C-STEPS is a feasible telephone counseling program that transcends geographic barriers, demonstrating the potential to decrease distress and promote coping and healthy lifestyles among cancer survivors.

Abstract
BACKGROUND To quantify changes in metamorphopsia and retinal contraction in eyes with idiopathic epiretinal membrane (ERM) before and after a spontaneous separation of ERM. METHODS Among 92 eyes of 92 patients with idiopathic ERM who were followed up at our hospital, 5 eyes of 5 patients had experienced a spontaneous separation of ERM during the follow-up period. Patient's metamorphopsia was assessed horizontally and vertically by a metamorphopsia chart developed by our group, M-CHARTS, to obtain the horizontal (MH) and vertical (MV) metamorphopsia scores. Difference in the scores before and after the membrane separation represents change in patient's metamorphopsia. Changes in retinal contraction were also evaluated horizontally and vertically with our original software for fundus image analysis. The difference between M-CHARTS scores and distances of retinal vessel movements with before and after membrane separation were measured. RESULTS All five subjects showed a decrease in the retinal contraction. Improved visual acuity was observed in three subjects, and no change was seen in the other two. Four subjects obtained better metamorphopsia scores after the membrane separation, while the other one was not detected with metamorphopsia by M-CHARTS either before or after the separation. In subjects with an improved MV, horizontal retinal movement was seen larger than the vertical movement. Similarly, the subjects with an improved MH indicated a larger vertical retinal movement than the horizontal movement. CONCLUSIONS The direction of patient's metamorphopsia closely associated with the direction of retinal contraction before and after a spontaneous separation of ERM.

Abstract
The purpose of this study was to determine whether the gamma-aminobutyric acid (GABA) affects the rate of brain protein synthesis in male rats. Two experiments were done on five or three groups of young rats (5 wk) given the diets containing 20% casein administrated 0 mg, 25 mg, 50 mg, 100 mg or 200 mg/100 g body weight GABA dissolved in saline by oral gavage for 1 day (d) (Experiment 1), and given the diets contained 0%, 0.25% or 0.5% GABA added to the 20% casein diet (Experiment 2) for 10 d. The plasma concentration of growth hormone (GH) was the highest in rats administrated 50 mg and 100 mg/100 g body weight GABA. The concentration of serum GABA increased significantly with the supplementation groups. The fractional (Ks) rates of protein synthesis in brain regions, liver and gastrocnemius muscle increased significantly with the 20% casein + 0.25% GABA diet and still more 20% casein + 0.5% GABA compared with the 20% casein diet. In brain regions, liver and gastrocnemius muscle, the RNA activity [g protein synthesized/(g RNA . d)] significantly correlated with the fractional rate of protein synthesis. The RNA concentration (mg RNA/g protein) was not related to the fractional rate of protein synthesis in any organ. Our results suggest that the treatment of GABA to young male rats are likely to increase the concentrations of plasma GH and the rate of protein synthesis in the brain, and that RNA activity is at least partly related to the fractional rate of brain protein synthesis.

Abstract
This study was designed to evaluate the antidepressant activity of various antidepressants using the learned helplessness test (LH) or the forced swimming test (FS) in rats. Repeated treatment of the tricyclic antidepressants imipramine (10 mg/kg, p.o.), clomipramine (0.625 mg/kg, p.o.), amitriptyline (10 mg/kg, p.o.) and amoxapine (20 mg/kg, p.o.) reduced the number of escape failures in the LH group, respectively. Repeated treatment of an atypical antidepressant, mianserin (2.5 and 5 mg/kg, p.o.), and one of the selective serotonin reuptake inhibitors (SSRI), fluvoxamine (1.25 mg/kg, p.o.), also reduced the number of escape failures in the LH group. In the FS, repeated treatment of imipramine (5, 10 mg/kg, p.o.), amitriptyline (5, 10 mg/kg, p.o.) and mianserin (10 mg/kg) significantly decreased the duration of immobility time. On the other hand, repeated treatment of amoxapine (5-20 mg/kg), clomipramine (0.1325-1.25 mg/kg, p.o.) and fluvoxamine (0.3125-1.25 mg/kg, p.o.) failed to decrease the duration of immobility time in the FS group. In conclusion, these results suggest that the LH group is sensitive to agents with a variety of antidepressant properties compared to the FS group in rats.

Abstract
In a rat forced swimming test (FS), we examined the effect of repeated injections of ACTH (adrenocorticotropic hormone) for 14 days on the decreased duration of immobility time produced by imipramine and desipramine. Both imipramine (15 and 30 mg/kg, p.o.) and desipramine (15 and 30 mg/kg, p.o.) significantly decreased the duration of immobility time in the FS. On the other hand, ACTH (100 microg/kg, i.p.) alone did not affect the duration of immobility time in FS. When ACTH (100 microg/kg, i.p.) was injected for 14 days before the 15-min swim session, it counteracted the decreased duration of immobility time induced by both imipramine and desipramine. Thus, ACTH seems to play a key role in decreasing the duration of immobility time of antidepressants in this test.

Abstract
Chronic administration of antidepressants has been shown to reduce the number of escape failures in the rat learned helplessness test (LH). In the present study we investigated the role of D1, D2 and D3 receptors in mediating this effect. In our first series of experiments, we demonstrated that SKF38393, D1 receptor agonist, in a dose of 2.5 mg/kg (i.p.) and quinpirole, D2 receptor agonist in a dose of 0.5 mg/kg (i.p.), significantly decreased the number of escape failures in LH, and these were reversed by SCH23390 (0.015 mg/kg), D1 receptor antagonist, and by sulpiride (25 mg/kg), D2 receptor antagonist, respectively. In contrast, 7-OH-DPAT, a D3 receptor agonist, in a dose of 10 mg/kg (i.p.) did not affect the number of escape failures in LH. In a second series of experiments, we showed that eight days of repeated treatment with imipramine (10 mg/kg, p.o.), fluvoxamine (1.25 mg/kg, p.o.) and tranylcypromine (1.25 mg/kg, p.o.) significantly decreased the number of escape failures in LH. The decrease in escape failures seen with use of imipramine and tranylcypromine was reversed by sulpiride in LH, but not by SCH23390. On the other hand, the effect of fluvoxamine was reversed by both SCH23390 and sulpiride. These findings indicate that stimulation of D1 and D2 receptors decreased the number of escape failures in LH, respectively. Thus, D2 and/or D1 receptors are probably involved in the decreased number of escape failures in case of repeated treatment with antidepressants in LH.

Abstract
Although many antipsychotics have affinities for sigma receptors, the transportation pathway of exogenous sigma(1) receptor ligands to intracellular type-1 sigma receptors are not fully understood. In this study, sigma(1) receptor ligand uptakes were studied using primary cultured neuronal cells. [(3)H](+)-pentazocine and [(3)H](R)-(+)-1-(4-chlorophenyl)-3-[4-(2-methoxyethyl)piperazin-1-yl]methyl-2-pyrrolidinone L-tartrate (MS-377), used as a selective sigma(1) receptor ligands, were taken up in a time-, energy- and temperature-dependent manner, suggesting that active transport mechanisms were involved in their uptakes. sigma(1) receptor ligands taken up into primary cultured neuronal cells were not restricted to agonists, but also concerned antagonists. The uptakes of these ligands were mainly Na(+)-independent. Kinetic analysis of [(3)H](+)-pentazocine and [(3)H]MS-377 uptake showed K(m) values (microM) of 0.27 and 0.32, and V(max) values (pmol/mg protein/min) of 17.4 and 9.4, respectively. Although both ligands were incorporated, the pharmacological properties of these two ligands were different. Uptake of [(3)H](+)-pentazocine was inhibited in the range 0.4-7.1 microM by all the sigma(1) receptor ligands used, including N,N-dipropyl-2-[4-methoxy-3-(2-phenylethoxy)phenyl]ethylamine monohydrochloride (NE-100), a selective sigma(1) receptor ligand. In contrast, the inhibition of [(3)H]MS-377 uptake was potently inhibited by haloperidol, characterized by supersensitivity (IC(50), approximately 2 nM) and was inhibited by NE-100 with low sensitivity (IC(50), 4.5 microM). Moreover, kinetic analysis revealed that NE-100 inhibited [(3)H]MS-377 uptake in a noncompetitive manner, suggesting that NE-100 acted at a site different from the uptake sites of [(3)H]MS-377. These findings suggest that there are at least two uptake pathways for sigma(1) receptor ligands in primary cultured neuronal cells (i.e. a haloperidol-sensitive pathway and another, unclear, pathway). In addition, pretreatment of cells with a calmodulin antagonist, N-(6-aminohexyl)-5-chloro-1-naphthalene sulfonamide (W-7), a myosin light chain kinase inhibitor, 1-(5-chloronaphthalene-1-sulfonyl)homopiperazine (ML-9), or microsomal Ca(2+)-ATPase inhibitors resulted in a reduction of the amount of sigma receptor ligand uptake. These findings suggest that the Ca(2+) pump on the endoplasmic reticulum and/or calmodulin-related events might be involved in the regulation of the uptake of sigma receptor ligands into primary neuronal cells.

Abstract
Neuropharmacological profiles of 5-(2-[4-(6-fluoro-1H-indole-3-yl) piperidine-1-yl] ethyl)-4-(4-fluorophenyl) thiazole-2-carboxylic acid amide (NRA0562) in rats were examined using electrophysiological and immunohistochemical methods. The firing rates of the substantia nigra pars compacta (A9) and the ventral tegmental area (A10) dopamine neurons were inhibited by methamphetamine (1 mg/kg, i.v.). NRA0562 dose-dependently reversed the inhibitory effects of methamphetamine on A9 and on A10 dopamine neurons. NRA0562 was more potent to reverse the inhibitory effects of methamphetamine on A10 (ED(50)=0.3 mg/kg) than on A9 (ED(50)=0.9 mg/kg) dopamine neurons. NRA0562 produced significant increases in Fos-like immunoreactivity in both the nucleus accumbens and the dorsolateral striatum. The difference between the number of Fos-like immunoreactivity produced by NRA0562 in the nucleus accumbens vs. dorsolateral striatum, referred to as the atypical index, was positive. Similar results could be observed with risperidone, an atypical antipsychotic. These results suggest that NRA0562 may have the atypical antipsychotic activities seen with risperidone, but without the liability of motor side effects typical of classical antipsychotics.

Abstract
Recently, various non-peptide corticotropin-releasing factor(1) (CRF(1)) receptor antagonists have been reported. Structure-affinity relationships (SARs) of non-peptide CRF(1) antagonists suggest that such antagonists can be constructed of three units: a hydrophobic unit (Up-Area), a proton accepting unit (Central-Area), and an aromatic unit (Down-Area). We previously presented 4-aryl-1,2,3,6-tetrahydropyridinopyrimidine derivatives including potent CRF receptor ligands 1a and 1b and proposed that the 4-aryl-1,2,3,6-tetrahydropyridino moiety might be useful as a substituent in the Up-Area. Our interest shifted to 5-aryl-1,2,3,6-tetrahydropyridinopyrimidine derivatives 2, among which compound 2m (CRA0165) had highest affinity for CRF(1) receptors (IC(50)=11nM). We report here the design, synthesis and SARs of derivatives 2.

Recently, various non-peptide corticotropin-releasing factor(1) (CRF(1)) receptor antagonists obtained by modification of the Central-Area have been reported. In contrast, we modified the Up-Area and presented 4- or 5-aryl-1,2,3,6-tetrahydropyridinopyrimidine derivatives including potent CRF receptor ligands 1a-c, and proposed that the 4- or 5-aryl-1,2,3,6-tetrahydropyridino moiety might be useful as a substituent in the Up-Area. Our interest shifted to the chemical modification in which the pyrimidine ring of 1a-c was replaced by other heterocycles, purine ring of 2, 3H-1,2,3-triazolo[4,5-d]pyrimidine ring of 3, purin-8-one ring of 4 and 7H-pyrrolo[2,3-d]pyrimidine ring of 5.

Abstract
The effects of virol A (VA), a toxic component of Cicuta virosa (water hemlock), on the GABA-induced Cl(-) current (I(GABA)) in acutely dissociated rat hippocampal CA1 neurons were investigated using whole-cell patch-clamp techniques. VA reversibly reduced I(GABA) and the muscimol (Mus)-induced current (I(Mus)) in a concentration-dependent manner. The IC(50) values for VA against I(GABA) and I(Mus) were 9.6x10(-7) and 9.8x10(-7) M, respectively. VA shifted the EC(50) value of I(GABA) from 6.5x10(-6) to 2.1x10(-5) M, whereas it had no effect on the maximum response, thereby suggesting that VA inhibited I(GABA) in a competitive manner. VA had no apparent effect on current-voltage relationships for I(GABA), thus indicating the lack of voltage-dependency. On the other hand, application of VA (10(-6) M) did not additionally reduce the I(GABA) suppressed by >10(-5) M picrotoxin. VA but not bicuculline accelerated the decay phase of I(GABA), as was seen with picrotoxin. Moreover, pre-application of 10(-5) M VA reduced I(GABA). VA did not inhibit that induced by glycine (10(-4) M). These results indicate that VA inhibits I(GABA) by acting both on the GABA agonist site and on the Cl(-) channel of the GABA(A) receptor-channel complex. VA is a structurally novel type of compound that selectively inhibits the GABA(A) receptor-Cl(-) channel complexes in mammalian central nervous system neurons.

Abstract
We have recently isolated a cDNA encoding a short isoform of the corticotropin-releasing factor (CRF) receptor subtype, referred to as CRF(2)alpha-tr, from the rat amygdala. The present study determined the localization of the truncated receptor mRNA in the rat brain by in situ hybridization histochemistry. The results showed significant levels of hybridization in the lateral septum, central nucleus of the amygdala, cortico-amygdaloid nucleus, ventromedial nucleus of the hypothalamus (VMH), and frontal cortex. In the physiological study, antidepressive drugs increased the expression of CRF(2)alpha-tr mRNA and the total binding activity to CRF in the rat amygdala. These findings suggest that CRF(2)alpha-tr may regulate endogeneous CRF release in the amygdala.

Abstract
(+)-2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylic acid (4, LY354740), a highly selective and orally active group II metabotropic glutamate receptor (mGluR) agonist, has increased interest in the study of group II mGluRs. Our interest focused on a conformationally constrained form of compound 4, because it appeared that the rigid form resulted in not only selectivity for group II mGluR but was orally active. Therefore, we introduced a fluorine atom to compound 4, based on the molecular size (close resemblance to hydrogen atom) and electronegativity (effects on the electron distribution in the molecule) of this atom and carbon-fluorine bond energy. Compound (+)-7 (MGS0008), the best compound among 3-fluoro derivatives 7-10, retained the agonist activity of compound 4 for mGluR2 and mGluR3 ((+)-7: EC(50) = 29.4 +/- 3.3 nM and 45.4 +/- 8.4 nM for mGluR2 and mGluR3, respectively; 4: EC(50) = 18.3 +/- 1.6 nM and 62.8 +/- 12 nM for mGluR2 and mGluR3, respectively) and increased the oral activity of compound 4 ((+)-7: ED(50) = 5.1 mg/kg and 0.26 mg/kg for phencyclidine (PCP)-induced hyperactivity and PCP-induced head-weaving behavior, respectively; 4: ED(50) = >100 mg/kg and 3.0 mg/kg for PCP-induced hyperactivity and PCP-induced head-weaving behavior, respectively). In addition, a compound [(3)H]-(+)-7 binding study using mGluR2 or 3 expressed in CHO cells was successful ((+)-7: K(i) = 47.7 +/- 17 nM and 65.9 +/- 7.1 nM for mGluR2 and mGluR3, respectively; 4: K(i) = 23.4 +/- 7.1 nM and 53.5 +/- 13 nM for mGluR2 and mGluR3, respectively). On the basis of a successful result of compound 7, we focused on the introduction of a fluorine atom on the C6 position of compound 4. (1R,2S,5R, 6R)-2-amino-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid ((-)-11) exhibited a high degree of agonist activity for group II mGluRs equal to that of compound 4 or 7 ((-)-11: K(i) = 16.6 +/- 5.6 and 80.9 +/- 31 nM for mGluR2 and mGluR3, respectively). Our interest shifted to modification on CH(2) at C4 position of compound 11, since replacement of the CH(2) group with either an oxygen atom or sulfur atom yielded compound 5 or 6, resulting in increased agonist activity. We selected a carbonyl group instead of CH(2) at the C4 position of compound 11. The carbonyl group might slightly change the relative conformation of three functional groups, the amino group and two carboxylic acids, which have important roles in mediating the interaction between group II mGluRs and their ligand, compared with the CH(2) group of 4, oxygen atom of 5, and sulfur atom of 6. (1R,2S,5S,6S)-2-Amino-6-fluoro-4-oxobicyclo[3.1. 0]hexane-2,6-dicarboxylic acid monohydrate ((+)-14, MGS0028) exhibited a remarkably high degree of agonist activity for mGluR2 (K(i) = 0.570 +/- 0.10 nM) and mGluR3 (K(i) = 2.07 +/- 0.40 nM) expressed in CHO cells but not mGluR4, 6, 7, 1a, or 5 expressed in CHO cells (K(i) = >100 000 nM). Furthermore, compound (+)-14 strongly inhibited phencyclidine (PCP)-induced head-weaving behavior (ED(50) = 0.090 microg/kg) and hyperactivity (ED(50) = 0.30 mg/kg) in rats. Thus, (+)-7 and (+)-14 are potent, selective, and orally active group II mGluR agonists and might be useful not only for exploring the functions of mGluRs but in the treatment of schizophrenia.

Abstract
The main biological role of angiotensin II type 2 receptor (AT2) has not been established. We made use of targeted disruption of the mouse AT2 gene to examine the functional role of the AT2 receptor in the central nervous system (CNS). We have previously shown that AT2-deficient mice displayed anxiety-like behavior in comparisons with wild-type mice. In the present study, we analyzed the pain threshold, learning behavior and brain edema formation using the tail-flick test, the tail-pinch test, the passive avoidance task and cold injury, respectively. In the passive avoidance task and cold injury, no differences were found between wild-type mice and AT2-deficient mice. In contrast, the pain threshold was significantly lower in AT2-deficient mice, compared with findings in wild-type mice. The immunohistochemical distribution of beta-endorphin in the brain was analyzed quantitatively in AT2-deficient mice and wild-type mice, using microphotometry. The fluorescence intensity of beta-endorphin in the arcuate nucleus of the medial basal hypothalamus (ARC) was significantly lower in AT2-deficient mice, compared with findings in wild-type mice. We found that the AT2 receptor does not influence learning behavior and brain edema formation. As AT2-deficient mice have increased sensitivity to pain and decreased levels of brain beta-endorphin, AT2 receptors may perhaps mediate regulation of the pain threshold.

Abstract
Cell therapy with human amniotic epithelial (HAE) cells was developed as an alternative method for enzyme replacement therapy in congenital lysosomal storage disorders, but only limited therapeutic efficacy has been reported. A major drawback is insufficient production and secretion of lysosomal enzymes from HAE cells. In this study, we infected HAE cells with an E1-deleted adenoviral vector expressing human beta-glucuronidase (GUSB), and generated cells overexpressing GUSB by a hundred times as much as endogenous GUSB in untreated HAE cells. GUSB secreted from the gene-transferred HAE cells were efficiently transported to murine fibroblasts with endocytosis mediated by mannose-6-phosphate receptors. The cells were administered into the spleen of the mice with the lysosomal storage disease mucopolysaccharidosis type VII (B6/MPSVII). Approximately 10-15% of the normal GUSB activity was detected in both liver and spleen 7 days after the cell administration. Histopathological examination showed that lysosomal enlargement in tissue macrophages in the liver and the spleen had disappeared by day 14. These results suggest that transplantation of the HAE cells transduced with adenoviral vectors can be employed for the treatment of congenital lysosomal storage disorders.

Abstract
As immediate-early genes (IEGs) are thought to play a critical role in mediating stimulus-induced neural plasticity, IEG response induced by methamphetamine (METH) has been characterized to define the changes in gene expression that may underlie its long-lasting behavioral effects. Although activation of several transcription factor IEGs has been described, little is known about effector IEGs. Here, we have examined whether METH administration affects expression of an effector IEG arc (activity-regulated, cytoskeleton-associated) that encodes a protein with homology to spectrin. Using in situ hybridization, we observed that METH caused a rapid and transient dose-dependent increase in arc mRNA level in the striatum and cortex that was abolished by pretreatment with the specific dopamine D1 receptor antagonist SCH-23390 but not by an atypical neuroleptic clozapine. METH induced arc mRNA in layers IV and VI of the cortex which dopamine receptor are localized to. These results suggest that D1 receptors are coupled to activation of arc gene, which may be involved in functional or structural alterations underlying neural plasticity triggered by METH.

Abstract
In vivo receptor labeling of the peripheral benzodiazepine receptor was investigated using ex vivo binding of [3H]-(2-chlorophenyl)-N-methyl-N-(1-methylpropyl)-3-isoquinoline-carb ox-amide ([3H]PK11195). In autoradiographic studies, high level specific binding of [3H]PK11195 was observed in the olfactory bulb. Intravenous administration of PK11195 dose-dependently (0.03-3 mg/kg) inhibited ex vivo binding of [3H]PK11195 in the olfactory bulb. Likewise, N-(2,5-dimethoxybenzyl)-N-(5-fluoro-2-phenoxyphenyl)acetamide (DAA1106), a newly identified peripheral benzodiazepine receptor-specific ligand, dose-dependently (0.1-100 mg/kg) reduced ex vivo binding of [3H]PK11195, when administered intraperitoneally. In contrast, clonazepam, a central benzodiazepine receptor-specific agonist, had negligible effects on ex vivo binding of [3H]PK11195. We propose that the ex vivo receptor binding technique we used will facilitate determination of in vivo receptor occupancy of the peripheral benzodiazepine receptor.

Abstract
Prolonged or high-intensity exposure to visible light leads to photoreceptor cell death. In this study, we demonstrate a novel pathway of light-induced photoreceptor apoptosis involving the low-affinity neurotrophin receptor p75 (p75NTR). Retinal degeneration upregulated both p75NTR and the high-affinity neurotrophin receptor TrkC in different parts of Müller glial cells. Exogenous neurotrophin-3 (NT-3) increased, but nerve growth factor (NGF) decreased basic fibroblast growth factor (bFGF) production in Müller cells, which can directly rescue photoreceptor apoptosis. Blockade of p75NTR prevented bFGF reduction and resulted in both structural and functional photoreceptor survival in vivo. Furthermore, the absence of p75NTR significantly prevented light-induced photoreceptor apoptosis. These observations implicate glial cells in the determination of neural cell survival, and suggest functional glial-neuronal cell interactions as new therapeutic targets for neurodegeneration.

Abstract
Recently, various non-peptide corticotropin-releasing factor1 (CRF1) receptor antagonists have been reported. Structure-affinity relationships (SARs) of non-peptide CRF antagonists suggest that such antagonists can be constructed of three units: a hydrophobic unit (Up-Area), a proton accepting unit (Central-Area), and an aromatic unit (Down-Area). Our interest focused on the Up-Area in deriving the novel methylidenepiperidine derivatives 8-10 and 4-aryl-1,2,3,6-tetrahydropyridine derivatives 11-13 as non-peptide CRF1 receptor antagonists. Compounds 8a and 11a had moderate affinity for CRF1 receptor, but compounds 9, 10, 12 and 13 did not exhibit CRF1 receptor affinity. Modification of derivatives 11 afforded compounds 11i (CRA1001) and 11x (CRA1000), which had high affinity and selectivity for CRF1 receptors with potent anxiolytic-like and antidepressant-like properties in some experimental animal models. These findings suggest that the hydrophonic unit (Up-Area) may be useful for design of CRF1 antagonists. We report here the design, synthesis and SARs of the derivatives 8 and 11 and isosteres 9, 10, 12 and 13.

Abstract
Extracellular single-unit activities of dopamine neurons were recorded using chloral hydrate anaesthetized rats. We examined the reversal effects of the selective dopamine D4 receptor blockers, NRA0160 (2-Carbamoyl-4-(4-fluorophenyl)-5-[2-[4-(3-fluorobenzylidene) piperidin-1-yl] ethyl] thiazole) and L-745,870 (3-[[4-(4-chlorophenyl) piperazin-1-yl] methyl]-1H-pyrrolo [2,3-b] pyridine), on dopamine agonists induced inhibition of dopamine neural activity. The firing rates of the substantia nigra pars compacta (A9) and the ventral tegmental area (A10) dopamine neurons were inhibited by methamphetamine (MAP: 1 mg/kg, i.v.) and apomorphine (APO: 40 microg/kg, i.v). NRA0160 dose-dependently reversed the inhibitory effects of MAP and APO on both A9 and A10 dopamine neurons. NRA0160 was more potent in reversing the inhibitory effects of both MAP and APO on A10 than A9 dopamine neurons. L-745,870 failed to reverse the inhibition produced by MAP on A9 and A10 dopamine neurons, whereas L-745,870, at the highest dose used, significantly reversed APO-induced inhibition of A10 but not A9 dopamine neurons. These results suggest that NRA0160 has different electrophysiological profiles on dopaminergic neural activity compared to L-745,870 and may have atypical antipsychotic effects.

Abstract
NRA0160, 5 - [2- ( 4- ( 3 - fluorobenzylidene) piperidin-1-yl) ethyl] - 4 -(4-fluorophenyl) thiazole-2-carboxamide, has a high affinity for human cloned dopamine D4.2, D4.4 and D4.7 receptors, with Ki values of 0.5, 0.9 and 2.7 nM, respectively. NRA0160 is over 20,000fold more potent at the dopamine D4.2 receptor compared with the human cloned dopamine D2L receptor. NRA0160 has negligible affinity for the human cloned dopamine D3 receptor (Ki=39 nM), rat serotonin (5-HT)2A receptors (Ki=180 nM) and rat alpha1 adrenoceptor (Ki=237 nM). NRA0160 and clozapine antagonized locomotor hyperactivity induced by methamphetamine (MAP) in mice. NRA0160 and clozapine antagonized MAP-induced stereotyped behavior in mice, although their effects did not exceed 50% inhibition, even at the highest dose given. NRA0160 and clozapine significantly induced catalepsy in rats, although their effects did not exceed 50% induction even at the highest dose given. NRA0160 and clozapine significantly reversed the disruption of prepulse inhibition (PPI) in rats produced by apomorphine. NRA0160 and clozapine significantly shortened the phencyclidine (PCP)-induced prolonged swimming latency in rats in a water maze task. These findings suggest that NRA0160 may have unique antipsychotic activities without the liability of motor side effects typical of classical antipsychotics.

Abstract
There are two known major angiotensin II receptor subtypes, type 1 (AT1) and type 2 (AT2), both of which are present in the brain. AT1 and AT2 receptors occur in characteristic distributions that are highly correlated with the distribution of angiotensin II-like immunoreactivity in nerve terminals. Acting through the AT1 receptor in the central nervous system, angiotensin II has effects on fluid and electrolyte homeostasis, neuroendocrine systems, autonomic pathways regulating cardiovascular function and behavior. While the role of the AT2 receptor in the brain is less well understood, recent knockout studies point to their involvement in behavioral and cardiovascular functions. We discuss here evidence regarding the function of the AT2 receptor in the brain, determined using mice lacking the AT2 receptor.

Abstract
It seems that many sigma ligands have been designed from known sigma ligands. We focused on a difference in structural flexibility between haloperidol and apomorphine, and studied chemical modification of apomorphine, a compound with high affinity for dopamine D2 receptors but not for sigma receptors, for discovery of sigma ligands. The first modification yielded good results with 6H-dibenzo[b,d]pyran analogues with weak affinity for sigma receptors but not D2 receptors. Furthermore, carbazole analogues, compounds designed from 6H-dibenzo[b,d]pyran analogues, potentially acted at sigma receptors with high selectivity. This paper describes the design, synthesis and sigma/D2 selectivity of 6H-dibenzo[b,d]pyran and carbazole analogues.

Abstract
We have previously reported that (R)-(+)-2-amino-4-(4-fluorophenyl)-5-[1-[4-(4-fluorophenyl)-4-oxobutyl]+ ++pyrrolidin-3-yl]thiazole (NRA0045) is a novel antipsychotic agent with affinities for dopamine D4, 5-hydroxytryptamine 2A (5-HT2A) and alpha1 receptors. In the present study, in vivo receptor occupancy of 5-HT2A, alpha1, dopamine D2 and D3 receptors by NRA0045 was assessed, based on in vivo and ex vivo receptor binding, and findings were compared to reference antipsychotic drugs (haloperidol, risperidone, clozapine). Intraperitoneal administration of haloperidol highly occupied the dopamine D2 receptor in the striatum and nucleus accumbens, and alpha1 adrenoceptors in the frontal cortex. Occupation of the 5-HT2A receptor in the frontal cortex and the dopamine D3 receptor in the nucleus accumbens and islands of Cajella was moderate. By contrast, atypical antipsychotics such as risperidone and clozapine dose-dependently occupied the 5-HT2A receptor in the frontal cortex, with moderate to negligible occupancy of the D2 receptor in the striatum and the nucleus accumbens. Clozapine and risperidone also occupied the alpha1 adrenoceptor in the frontal cortex, and clozapine did not occupy the dopamine D3 receptor. As seen with other atypical antipsychotics, intraperitoneal administration of NRA0045 dose-dependently occupied the 5-HT2A receptor and the alpha1 adrenoceptor in the frontal cortex, while it was without effect on dopamine D2 and D3 receptors in the striatum, nucleus accumbens and islands of Cajella. Thus, the strong occupancy of 5-HT2A and alpha1 receptors is involved in the pharmacological action of NRA0045.

Abstract
This is a review on the recent results of research on sigma-receptor antagonists. NE-100, a selective sigma1-receptor antagonist, shows improvement of abnormal behaviors and cognitive dysfunction induced by phencyclidine (PCP). However, NE-100 does not inhibit dopamine agonist-induced behaviors nor induces catalepsy. The mode of action of NE-100 is estimated to be the indirect modulation of the NMDA/PCP-receptor ion channel complex and the modulation of dopamine release from the dopaminergic nerve terminals. The recently reported MS-355/MS-377, which is also a selective sigma1-receptor antagonist, has a similar pharmacological profiles as NE-100, but in addition, MS-355/MS-377 inhibits methamphetamine-induced formation of reversal tolerance and also inhibits apomorphine-induced climbing behavior like dopamine D2-receptor antagonists. The report on clinical trial targeting schizophrenia shows results on rimcazole, remoxipride, BMY 14802, panamesine (EMD 57445) and SL 82.0715. Rimcazole was effective in the open study, but the double blind trial was discontinued due to seizure induction. Remoxipride showed efficacy different from those of dopamine D2-receptor antagonists (less extrapyramidal adverse effects), but the trial was discontinued due to occurrence of aplastic anemia. Panamesine and SL 82.0714 showed favorable efficacy in the open studies, but BMY 14802 showed no efficacy in clinical trials.

Abstract
The encoding extrinsic 12-kDa protein of oxygen-evolving PS II complex from a red alga, Cyanidium caldarium, was cloned and sequenced by means of PCR and a rapid amplification of cDNA ends (RACE) procedure. The gene encodes a putative polypeptide of 154 amino acids with a calculated molecular mass of 16,714 Da. The full sequence of the protein includes two characteristic transit peptides, one for transfer across the chloroplast envelope and another for targeting into the thylakoid lumen. This indicates that the protein is encoded in the nuclear genome. The mature protein consists of 93 amino acids with a calculated molecular mass of 10,513 Da. The cloned gene was successfully expressed in Escherichia coli and the resulting protein was purified, reconstituted to CaCl2-washed PS II complex together with the other extrinsic proteins of 33 and 20 kDa and cyt c-550. The recombinant 12-kDa protein bound completely with the PSII complex, which resulted in a restoration of oxygen evolution equal to the level achieved by binding of the native 12-kDa protein.

Abstract
Pharmacological characteristics of NRA compounds, novel atypical antipsychotics, were compared with those of clozapine and haloperidol, in regard to modification of Fos-like immunoreactivity (FLI) in rats. (R)-(+)-2-Amino-4-(4-fluorophenyl)-5-[1-[4-(4-fluorophenyl)-4-oxobutyl] pyrrolidin-3-yl] thiazole (NRA0045) and 2-carbamoyl-4-phenyl-5-[2-[4-(4-fluorobenzylidene) piperidin-1-yl] ethyl] thiazole (NRA0215) have a high affinity for dopamine D4 receptors, serotonin2A receptors, and the alpha1 adrenoceptor. 2-Carbamoyl-4-(4-fluorophenyl)-5-[2-[4-(3-fluorobenzylidene) piperidin-1-yl] ethyl] thiazole (NRA0160) has a selective and high affinity for dopamine D4 receptors. NRA0045 and clozapine (10 and 30 mg/kg, IP) produced significant increases in FLI in both the nucleus accumbens (N. Acc.) and the medial prefrontal cortex (mPFC) but not in the dorsolateral striatum (DLS). In contrast, NRA0160 and NRA0215 (10 and 30 mg/kg, IP) significantly increased FLI in the mPFC but not in the N. Acc. and the DLS. Haloperidol (0.1 and 1 mg/kg, IP) significantly produced FLI in the N. Acc., the DLS, and the mPFC. These data indicate that the antagonistic effects of dopamine D4 receptors may contribute, at least in part, to the actions of NRA0045, NRA0160, and NRA0215 in the mPFC.

Abstract
Receptor binding and behavioral profiles of N-(4-chloro-2-phenoxyphenyl)-N-(2-isopropoxybenzyl)acetamide (DAA1097) and N-(2,5-dimethoxybenzyl)-N-(5-fluoro-2-phenoxyphenyl)acetamide (DAA1106), novel, selective agonists for the peripheral benzodiazepine receptor (PBR) were examined. DAA1097 and DAA1106 inhibited [3H]PK 11195 binding to crude mitochondrial preparations of rat whole brain, with IC50 values of 0.92 and 0.28 nM. Likewise, DAA1097 and DAA1106 inhibited [3H]Ro 5-4864 binding to the same mitochondrial preparation, with IC50 values of 0.64 and 0.21 nM. In contrast, DAA1097 and DAA1106 did not inhibit [3H]-flunitrazepam, the central benzodiazepine receptor (CBR) ligand, binding to membranes of rat whole brain (IC50>10,000nM). Oral administration of DAA1097 and DAA1106 had anxiolytic effects in the mouse light/dark exploration test and in the rat elevated plus- maze test. Oral administration of DAA1106, diazepam and buspirone but not DAA1097 significantly increased sleeping time in hexobarbital-induced anesthesia in mice. The order of potency of potentiation of hexobarbital anesthesia was diazepam> buspirone> DAA1106> DAA1097. Oral administration of DAA1097 and DAA1106 but not diazepam and buspirone did not affect spontaneous locomotor activity in mice. These findings indicate that DAA1097 and DAA1106 are PBR selective ligands with potent anxiolytic-like properties, in laboratory animals.

Abstract
Receptor binding, behavioral, and electrophysiological profiles of 2-[N-(2-methylthio-4-isopropylphenyl)-N-ethylamino]-4-[4-(3-flu orophe nyl)-1,2,3,6-tetrahydropyridin-1-yl)-6-methylpyrimidine (CRA1000) and 2-[N-(2-bromo-4-isopropylphenyl)-N-ethylamino]-4-[4-(3-fluoropheny l)- 1,2,3,6-tetrahydropyridin-1-yl)-6-methylpyrimidine (CRA1001), putative novel and selective antagonists for corticotropin-releasing factor1 (CRF1) receptor were examined. Both CRA1000 and CRA1001 inhibited 125I-ovine CRF binding to membranes of rat frontal cortex with IC50 values of 20.6 and 22.3 nM, respectively. Likewise, CRA1000 and CRA1001 inhibited 125I-ovine CRF binding to membranes of rat pituitary. In contrast, both CRA1000 and CRA1001 were without affinity for the CRF2beta receptor when examined using rat heart. In mice orally administered CRA1000 and CRA1001 reversed the swim stress-induced reduction of the time spent in the light area in the light/dark exploration task. In nonstress conditions, CRA1000 and CRA1001 were without effect on the time spent in the light area in the same task in mice. Orally administered CRA1000 and CRA1001 dose dependently reversed the effects of i.c.v. infusion of CRF on time spent in the open arms in the elevated plus-maze in rats. Lesioning of olfactory bulbs induced hyperemotionality, and this effect was inhibited by either acute or chronic oral administration of CRA1000 and CRA1001 in rats. The firing rate of locus coeruleus neurons was increased by i.c.v.-infused CRF. This excitation of locus coeruleus neurons was significantly blocked by pretreatment with i.v. administration of CRA1000 and CRA1001. CRA1000 and CRA1001 had no effects on the hexobarbital-induced anesthesia in mice, the rotarod test in mice, the spontaneous locomotor activity in mice, and a passive avoidance task in rats. These observations indicate that both CRA1000 and CRA1001 are selective and competitive CRF1 receptor antagonists with potent anxiolytic- and antidepressant-like properties in various experimental animal models, perhaps through inhibition of CRF1 receptors. CRA1000 and CRA1001 may prove effective for treating subjects with depression- and/or anxiety-related disorders without the side effects seen in the related currently prescribed medications.
