Abstract
Trauma and stressor-related symptoms have been frequently reported during the COVID-19 pandemic. Few studies compare post-traumatic stress symptoms (PTSS) between patients and non-infected controls. Using data from an ongoing natural history study of COVID-19, this study compared PTSS between patients infected with SARS-CoV-2 during the first year of the pandemic and controls. Within the COVID-19 patient cohort, we also compared PTSS between patients with and without post-COVID conditions, also known as post-acute sequelae of SARS-CoV-2 infection (PASC). This study also examined the association of PTSS with trait resilience and prior trauma exposure. PTSS were assessed using the Impact of Event Scaled-Revised (IES-R), which has a validated probable PTSD cutoff (score ≥33). The results showed that patients (n=131) reported significantly higher IES-R scores than controls (n=82) and had significantly higher odds of having scores indicative of PTSD [AOR: 4.17 p: 0.029]. IES-R scores among PASC patients (n=68) were significantly elevated compared to patients without PASC (n=63) and PASC patients did not have higher odds for probable PTSD [AOR: 2.60; p: 0.14]. Trait resilience was associated with lower PTSS. These findings help characterize the mental health impact of the COVID-19 illness experience and highlight elevated PTSS in patients with persistent post-COVID conditions.

Abstract
PURPOSE/OBJECTIVE(S) Glypican-3 (GPC-3), a heparan sulfate proteoglycan involved in cellular proliferation, modulates signaling of FGF/FGFR, IGF/IGFR, HGF/Met, Wnt/Frizzled, among others and correlates with survival. GPC-3 is overexpressed in the majority of hepatocellular carcinoma and hepatoblastoma, but not in normal hepatocytes. Accordingly, it is being investigated as a liver cancer-selective target for radiopharmaceutical imaging and therapy. However, the potential linkage between GPC-3 expression and radiosensitivity has not yet been defined. In this study, we investigated the effects of GPC-3 deficiency on radiosensitivity in liver cancer cell lines. MATERIALS/METHODS CRISPR/Cas9 system was used to engineer GPC-3 knockout variants of liver cancer cell lines, HepG2 & Hep3B, both of which natively express GPC-3. Confirmation of knockout of GPC-3 was evaluated by RT-PCR, western blotting, flow cytometry, immunocytochemistry, and gDNA sequencing. Cell growth and migration were evaluated by BrdU insertion and wound-healing assays, respectively. In vitro radiosensitivity was examined by radiation-induced apoptosis/necrosis (Annexin V-APC and PI staining), cell cycle modification, γH2AX foci formation, and clonogenic assays (6 Gy). Wildtype and knockout lines were engrafted into athymic mice to assess tumor growth kinetics. RESULTS RT-PCR, western blotting, flow cytometry, and immunocytochemistry all confirmed GPC-3 knockout in both HepG2 and Hep3B cell lines. Nucleotide deletion at exon 3 of the GPC-3 gene was confirmed by gDNA sequencing in HepG2ΔGPC3 and Hep3BΔGPC3. GPC-3 deficiency reduced liver cancer cell proliferation (HepG2ΔGPC3, p = 0.027, and Hep3BΔGPC3, p = 0.031) and migration (HepG2ΔGPC3: 1.5-fold, p<0.001, and Hep3BΔGPC3: 2.3-fold, p<0.001) significantly when compared with wild type. GPC-3 deficiency reduced cell survival and clonogenicity (HepG2ΔGPC3: DEF = 1.23, Hep3BΔGPC3: DEF = 1.23) in liver cancer cells exposed to irradiation (6 Gy). The delayed repair of double-stranded DNA damage was observed in irradiated GPC-3 deficient liver cancer cells. Tumor growth was dramatically delayed by GPC-3 deficiency. Tumor weight measured at 50 (Hep3B) and 60 (HepG2) days after liver cancer cell inoculation corroborated these effects. CONCLUSION Knockout lines of HepG2 and Hep3B exhibited decreased cell proliferation, migration, and in vivo tumor growth compared to wildtype. GPC-3 deficiency was associated with increased sensitivity to radiation therapy. Studies identifying the pathways through which this radiosensitivity is mediated are ongoing.

Abstract
PURPOSE/OBJECTIVE(S) Despite advances in the diagnosis and treatment of hepatocellular carcinoma (HCC), there are no tumor-selective agents that are clinically approved in the US for this disease. Here, we aimed to identify and validate molecules that are overexpressed on HCC plasma membrane compared to normal tissues, which could be facilitate the design, engineering, and testing of tumor-selective imaging and therapeutic agents. MATERIALS/METHODS We analyzed next-generation sequencing (NGS) public datasets (TCGA and TIGER-LC) and NCI single cell RNA-sequencing datasets to identify overexpressed plasma membrane molecules and aimed to validate these targets using immunohistochemical staining (IHC) of patient tissue microarrays (TMAs), and flow cytometry using liver cancer cell lines (Huh7, HepG2, and Hep3B). RESULTS NGS data identified GPC3, EGFR, MET, MUC13, and ROBO1 molecules overexpressed in HCC relative to non-tumor tissues. In HepG2 cell line, EGFR (p<0.05) and MET (p<0.01) demonstrated statistically significant increased median fluorescence intensity (MFI) relative to controls in flow cytometry. In the Hep3B cell line, MET, GPC3, and EGFR demonstrated an increased MFI relative to the control (p<0.01). No statistically significant difference was observed in Huh7 cell lines. IHC staining of TMAs for GPC3, MET, MUC14, and ROBO1 showed statistically significantly higher staining relative to the normal tumor tissue (p<0.001). CONCLUSION We identified and validated plasma membrane molecules overexpressed in HCC compared to non-tumor tissue. Because GPC3, a well-known HCC-specific marker that is expressed in 75% of HCC, was identified using our approach, we are confident that that additional molecules may also represent promising HCC-selective targets. This work could facilitate the design, engineering, and testing of novel precision oncology imaging and therapeutic agents for HCC.

Abstract
BACKGROUND The COVID-19 pandemic and its associated restrictions have been a major stressor that has exacerbated mental health worldwide. Qualitative data play a unique role in documenting mental states through both language features and content. Text analysis methods can provide insights into the associations between language use and mental health and reveal relevant themes that emerge organically in open-ended responses. OBJECTIVE The aim of this web-based longitudinal study on mental health during the early COVID-19 pandemic was to use text analysis methods to analyze free responses to the question, "Is there anything else you would like to tell us that might be important that we did not ask about?" Our goals were to determine whether individuals who responded to the item differed from nonresponders, to determine whether there were associations between language use and psychological status, and to characterize the content of responses and how responses changed over time. METHODS A total of 3655 individuals enrolled in the study were asked to complete self-reported measures of mental health and COVID-19 pandemic-related questions every 2 weeks for 6 months. Of these 3655 participants, 2497 (68.32%) provided at least 1 free response (9741 total responses). We used various text analysis methods to measure the links between language use and mental health and to characterize response themes over the first year of the pandemic. RESULTS Response likelihood was influenced by demographic factors and health status: those who were male, Asian, Black, or Hispanic were less likely to respond, and the odds of responding increased with age and education as well as with a history of physical health conditions. Although mental health treatment history did not influence the overall likelihood of responding, it was associated with more negative sentiment, negative word use, and higher use of first-person singular pronouns. Responses were dynamically influenced by psychological status such that distress and loneliness were positively associated with an individual's likelihood to respond at a given time point and were associated with more negativity. Finally, the responses were negative in valence overall and exhibited fluctuations linked with external events. The responses covered a variety of topics, with the most common being mental health and emotion, social or physical distancing, and policy and government. CONCLUSIONS Our results identify trends in language use during the first year of the pandemic and suggest that both the content of responses and overall sentiments are linked to mental health.

Abstract
BACKGROUND Several studies report the incidence of psychiatric symptoms and disorders among patients who recovered from coronavirus disease 2019 (COVID-19); however, little is known about the emotional impact of acute COVID-19 illness and recovery on these survivors. Qualitative methods are ideal for understanding the psychological impact of a novel illness. OBJECTIVE To describe the emotional experience of the acute COVID-19 illness and recovery in patients who contracted the virus during the early months of the pandemic. METHODS Semi-structured interviews conducted by consultation-liaison (C-L) psychiatrists were used to elicit participant responses about the emotional impact of the acute and recovery phases of the COVID-19 illness. Participants recruited from the Maryland, District of Columbia, and Virginia area were interviewed which was audio recorded between June 2020 and December 2020. The research team extracted qualitative themes from the recordings using the principles of thematic analysis. RESULTS One hundred and one COVID-19 survivors (54 women; mean [SD] age, 50 [14.7] years) were interviewed at a mean of 5.16 months after their acute illness, and their responses were audio-recorded. Most participants were White (77%), non-Hispanic/Latino (86.1%), and not hospitalized for COVID-19 (87.1%). Coders identified 26 themes from participant responses. The most frequently coded themes included anxiety/worry (49), uncertainty (37), supportfrom others (35), alone/isolation (32), and positive reframe/positive emotions (32). CONCLUSIONS Survivors who contracted severe acute respiratory syndrome coronavirus 2 during the early months of the pandemic described both negative and positive valence emotions. They experienced emotional distress and psychosocial stressors associated with the acute illness and recovery but also drew upon personal resiliency to cope. This report highlights the utility of qualitative research methods in identifying emotional responses to a novel illness that may otherwise go unnoted. Consultation-liaison psychiatrists may be uniquely positioned to work in collaboration with medical colleagues in developing a multidimensional approach to evaluating an emerging illness.

Abstract
OBJECTIVES The DSM-5 Level 1 Cross-Cutting Symptom Measure (DSM-XC) was developed by the American Psychiatric Association as a transdiagnostic mental health symptom survey. Despite its promise as a screening tool, few studies have assessed its latent dimensionality or provided guidance on interpreting responses. We examined the factor structure of the DSM-XC in a convenience sample of participants with varying degrees of psychopathology. METHODS Participants (n = 3533) were enrolled in an online study on the mental health impact of COVID-19 (NCT04339790). We used a factor analytic framework with exploratory and confirmatory analyses to evaluate candidate factor solutions. Convergent validity analysis with concurrent study measures was also performed. RESULTS Six-factor and bifactor candidate solutions both had good fit and full measurement invariance across age, sex, and enrollment date. The six-factor solution resulted in constructs labeled as: mood, worry, activation, somatic, thought, and substance use. A general psychopathology factor and two residual factors (mood and anxiety constructs) explained the variance of the bifactor solution. CONCLUSIONS Our analysis supports that the DSM-XC is a multidimensional instrument spanning many mental health symptoms. We provide scoring solutions for two factor structures that capture broader constructs of psychopathology. Use of a convenience sample may limit generalizability of findings.

Abstract
BACKGROUND A substantial proportion of persons who develop COVID-19 report persistent symptoms after acute illness. Various pathophysiologic mechanisms have been implicated in the pathogenesis of postacute sequelae of SARS-CoV-2 infection (PASC). OBJECTIVE To characterize medical sequelae and persistent symptoms after recovery from COVID-19 in a cohort of disease survivors and controls. DESIGN Cohort study. (ClinicalTrials.gov: NCT04411147). SETTING National Institutes of Health Clinical Center, Bethesda, Maryland. PARTICIPANTS Self-referred adults with laboratory-documented SARS-CoV-2 infection who were at least 6 weeks from symptom onset were enrolled regardless of presence of PASC. A control group comprised persons with no history of COVID-19 or serologic evidence of SARS-CoV-2 infection, recruited regardless of their current health status. Both groups were enrolled over the same period and from the same geographic area. MEASUREMENTS All participants had the same evaluations regardless of presence of symptoms, including physical examination, laboratory tests and questionnaires, cognitive function testing, and cardiopulmonary evaluation. A subset also underwent exploratory immunologic and virologic evaluations. RESULTS 189 persons with laboratory-documented COVID-19 (12% of whom were hospitalized during acute illness) and 120 antibody-negative control participants were enrolled. At enrollment, symptoms consistent with PASC were reported by 55% of the COVID-19 cohort and 13% of control participants. Increased risk for PASC was noted in women and those with a history of anxiety disorder. Participants with findings meeting the definition of PASC reported lower quality of life on standardized testing. Abnormal findings on physical examination and diagnostic testing were uncommon. Neutralizing antibody levels to spike protein were negative in 27% of the unvaccinated COVID-19 cohort and none of the vaccinated COVID-19 cohort. Exploratory studies found no evidence of persistent viral infection, autoimmunity, or abnormal immune activation in participants with PASC. LIMITATIONS Most participants with COVID-19 had mild to moderate acute illness that did not require hospitalization. The prevalence of reported PASC was likely overestimated in this cohort because persons with PASC may have been more motivated to enroll. The study did not capture PASC that resolved before enrollment. CONCLUSION A high burden of persistent symptoms was observed in persons after COVID-19. Extensive diagnostic evaluation revealed no specific cause of reported symptoms in most cases. Antibody levels were highly variable after COVID-19.

Abstract
This study assessed the relationship between contact with COVID-19 patients and the mental health of healthcare workers (HCWs) in the United States (US). In a convenience sample of 957 HCWs who completed an anonymous online survey between April-May 2020, HCWs who provided direct care to confirmed or suspected COVID-19 patients reported increased depressive and posttraumatic symptoms compared to HCWs with no COVID-19 patient contact. Additionally, more frequent contact was associated with higher distress. More data drawn from diverse samples that better represent US HCWs are needed to fully assess the scope of this association.

Abstract
We report on the utility of online self-perceived medical and mental health ratings (SPH) when screening healthy volunteers for mental health research. These one-item ratings were correlated with eligibility decisions and longer clinical surveys. We found correlations between SPH ratings and blinded clinician ratings of volunteer medical and mental health after an in-person evaluation, although additional analysis revealed poor reliability between clinician and volunteer ratings. SPH ratings are a useful addition to screening methods for research studies.

Abstract
Background The COVID-19 pandemic led to dramatic threats to health and social life. Study objectives - develop a prediction model leveraging subsample of known Patient/Controls and evaluate the relationship of predicted mental health status to clinical outcome measures and pandemic-related psychological and behavioral responses during lockdown (spring/summer 2020). Methods Online cohort study conducted by National Institute of Mental Health Intramural Research Program. Convenience sample of English-speaking adults (enrolled 4/4-5/16/20; n=1,992). Enrollment measures: demographics, clinical history, functional status, psychiatric and family history, alcohol/drug use. Outcome measures (enrollment and q2 weeks/6 months): distress, loneliness, mental health symptoms, and COVID-19 survey. NIMH IRP Patient/Controls survey responses informed assignment of Patient Probability Scores (PPS) for all participants. Regression models analyzed the relationship between PPS and outcome measures. Outcomes Mean age 46.0 (±14.7), female (82.4%), white (88.9 %). PPS correlated with distress, loneliness, depression, and mental health factors. PPS associated with negative psychological responses to COVID-19. Worry about mental health (OR 1.46) exceeded worry about physical health (OR 1.13). PPS not associated with adherence to social distancing guidelines but was with stress related to social distancing and worries about infection of self/others. Interpretation Mental health status (PPS) was associated with concurrent clinical ratings and COVID-specific negative responses. A focus on mental health during the pandemic is warranted, especially among those with mental health vulnerabilities. We will include PPS when conducting longitudinal analyses of mental health trajectories and risk and resilience factors that may account for differing clinical outcomes. Funding NIMH (ZIAMH002922); NCCIH (ZIAAT000030).

Abstract
The DSM-5 Level 1 Cross-Cutting Symptom Measure (DSM-XC) is a transdiagnostic mental health symptom measure that has shown promise in informing clinical diagnostic evaluations and as a screening tool for research. However, few studies have assessed the latent dimensionality of the DSM-XC or provided guidance on how to score the survey. In this report, we examined the factor structure of the DSM-XC in a sample of over 3500 participants enrolled in a protocol on the mental health impact of COVID-19 conducted through the National Institute of Mental Health Intramural Research Program (NIMH IRP) ( ClinicalTrials.gov identifier: NCT04339790 ). We began by conducting an exploratory factor analysis (EFA) to identify the best solution for our data, and then employed a confirmatory factor analyses (CFAs) to evaluate the fit of the two-factor solution proposed by Lace and Merz (Lace & Merz, 2020), the fit of our proposed solution, and the measurement invariance of our proposed solution across age, sex, and calendar time. We found a six-factor solution stemming from our EFAs to best fit our data. Each factor captures symptoms related to a specific construct of psychopathology: mood, worry, activation, somatic, confusion, and substance use. Future research should evaluate this six-factor structure using additional datasets to confirm its consistency across research populations and settings.

Abstract
The DSM-5 Level 1 Cross-Cutting Symptom Measure-Adult (DSM XC) was developed by the American Psychiatric Association (APA) as a transdiagnostic measure of current mental health symptomatology. This paper describes utilization of the DSM XC to screen volunteers for participation in mental health research studies as healthy controls. Research volunteers completed an online, modified version of the DSM XC, which along with other clinical information, was used to determine eligibility for participation as a healthy control. The sensitivity and specificity of screening positive on the DSM XC for this eligibility decision were calculated. Of 506 volunteers who completed the screening process, 159 (31%) were ineligible due to mental health reasons. The DSM XC sensitivity in predicting this determination was 64.2% [95% CI: 56.5 - 71.3] and its specificity was 83.9% [95% CI: 79.7 - 87.5]. When DSM XC responses were combined with information about current psychotropic medication use, an important determinant of study eligibility, the sensitivity improved to 81.8% [95% CI: 75.3 - 87.2). These findings provide preliminary support for the use of the DSM XC as an initial screening tool for mental health studies that enroll healthy research volunteers, particularly when supplemented by additional clinical history such as psychotropic medication use.

Abstract
OBJECTIVE The goal of this study was to identify trends in MD/PhD graduates entering psychiatry, to compare these trends with other specialties, and to review strategies for enhancing the physician-scientist pipeline. METHODS Data on 226,588 medical students graduating from Liaison Committee on Medical Education accredited programs between 1999 and 2012 (6626 MD/PhDs) were used to evaluate the number, percentage, and proportion of MD/PhDs entering psychiatry in comparison with other specialties (neurology, neurosurgery, internal medicine, family medicine, and radiation oncology). Linear regression and multiple linear regression determined whether these values increased over time and varied by sex. RESULTS Over 14 years, an average of 18 MD/PhDs (range 13-29) enrolled in psychiatry each year. The number of MD/PhDs going into psychiatry significantly increased, although these gains were modest (less than one additional MD/PhD per year). The proportion of students entering psychiatry who were MD/PhDs varied between 2.9 and 5.9 per 100 residents, with no significant change over time. There was also no change in the percentage of MD/PhDs entering psychiatry from among all MD/PhD graduates. The rate of increase in the number of MD/PhDs going into psychiatry did not differ significantly from other specialties except for family medicine, which is decreasing. The rate of MD/PhDs going into psychiatry was higher for women, suggesting closure of the sex gap in 17 years. CONCLUSIONS Despite the increase in the number of MD/PhDs entering psychiatry, these numbers remain low. Expanding the cohort of physician-scientists dedicated to translational research in psychiatry will require a multipronged approach.

Abstract
OBJECTIVE Human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) have gained popularity as a promising cell source for regenerative medicine, but limited in vivo studies have reported cartilage repair. In addition, the roles of MSCs in cartilage repair are not well-understood. The purpose of this study was to investigate the feasibility of transplanting hUCB-MSCs and hyaluronic acid (HA) hydrogel composite to repair articular cartilage defects in a rabbit model and determine whether the transplanted cells persisted or disappeared from the defect site. DESIGN Osteochondral defects were created in the trochlear grooves of the knees. The hUCB-MSCs and HA composite was transplanted into the defect of experimental knees. Control knees were transplanted by HA or left untreated. Animals were sacrificed at 8 and 16 weeks post-transplantation and additionally at 2 and 4 weeks to evaluate the fate of transplanted cells. The repair tissues were evaluated by gross, histological and immunohistochemical analysis. RESULTS Transplanting hUCB-MSCs and HA composite resulted in overall superior cartilage repair tissue with better quality than HA alone or no treatment. Cellular architecture and collagen arrangement at 16 weeks were similar to those of surrounding normal articular cartilage tissue. Histological scores also revealed that cartilage repair in experimental knees was better than that in control knees. Immunohistochemical analysis with anti-human nuclear antibody confirmed that the transplanted MSCs disappeared gradually over time. CONCLUSION Transplanting hUCB-MSCs and HA composite promote cartilage repair and interactions between hUCB-MSCs and host cells initiated by paracrine action may play an important role in cartilage repair.

Abstract
To explore potential biomarkers for amoxicillin/clavulanate‐induced liver injury (AC‐DILI), we conducted a clinical trial in 32 healthy subjects based on multi‐omics approaches. Every subject was administered amoxicillin/clavulanate for 14 days. The liver‐specific microRNA‐122 (miR‐122) level increased prior to and correlated well with the observed alanine aminotransferase (ALT) level increase. This result indicates its potential as a sensitive early marker for AC‐DILI. We also identified urinary metabolites, such as azelaic acid and 7‐methylxanthine, with levels that significantly differed among the groups classified by ALT elevation level on day 8 after drug administration (P < 0.05). Lymphocyte proliferation in response to the drug was also observed. These findings demonstrate sequential changes in the process of AC‐DILI, including metabolic changes, increased miR‐122 level, increased liver enzyme activity, and enhanced lymphocyte proliferation after drug administration. In conclusion, this study provides potential biomarkers for AC‐DILI based on currently known mechanisms using comprehensive multi‐omics approaches.

Abstract
Measures of psychological trauma are rarely evaluated for validity with disadvantaged populations. The authors used three qualitative methods to assess the cultural validity of the Stressful Life Events Screening Questionnaire (SLESQ) with low-income African American women. Focus groups ( n = 17), cognitive interviews ( n = 20), and videotape reviews of SLESQ interviews were conducted ( n = 16). Focus group participants spontaneously used similar language to the SLESQ items and tended to identify SLESQ events as traumatic. Most items were well understood in the interviews, with some criticism of wording. Tape reviews indicated little wording modification by interviewers. One item showed consistent problems. The interview was revised accordingly.

Abstract
PURPOSE To determine intraocular pharmacokinetic properties of intravitreally injected vascular endothelial growth factor (VEGF)-Trap in a rabbit model. METHODS VEGF-Trap was intravitreally injected in 18 rabbit eyes. Eyes were enucleated 1 h and 1, 2, 5, 14, and 30 days after injections and immediately frozen at -80 °C. Concentration of VEGF-Trap in vitreous, aqueous humor, and retina/choroid was determined using an indirect enzyme-linked immunosorbent assay and analyzed to obtain pharmacokinetic properties. RESULTS Maximum concentration of VEGF-Trap was achieved at 1 h in all three tissues. A one-compartment model of distribution was selected as the final model for all tissues studied. Estimated half-life of VEGF-Trap in vitreous, aqueous humor, and retinal/choroid was 87.1, 36.8, and 35.0 h, respectively, and estimated mean residence time was 125.7, 53.1, and 50.5 h, respectively. Area under the curve from time 0 to the end point was 10009.8, 3945.1, and 1189.3, respectively. Total exposure of the aqueous humor and retina/choroid to VEGF-Trap was 39.4% and 11.9% of vitreous exposure, respectively. CONCLUSION The vitreous half-life of VEGF-Trap is 3.63 days. This is shorter than that of bevacizumab (6.99 days) and longer than that of ranibizumab (2.51 days), as shown in studies using the same experimental settings. The concentration of VEGF-Trap peaked at 1 h after injections in all eye tissues studied.

Abstract
Translocator protein (TSPO; 18 kDA) is a high-affinity cholesterol-binding protein that is integrally involved in cholesterol transfer from intracellular stores into mitochondria, the rate-determining step in steroid formation. Previous studies have shown that TSPO drug ligands are able to activate steroid production by MA-10 mouse Leydig tumor cells and by mitochondria isolated from steroidogenic cells. We hypothesized herein that the direct, pharmacological activation of TSPO might induce aged Leydig cells, which are characterized by reduced T production, to produce significantly higher levels of T both in vitro and in vivo. To test this, we first examined the in vitro effects of the TSPO selective and structurally distinct drug ligands N,N-dihexyl-2-(4-fluorophenyl)indole-3-acetamide (FGIN-1-27) and benzodiazepine 4'-chlorodiazepam (Ro5-4864) on steroidogenesis by Leydig cells isolated from aged (21-24 months old) and young adult (3-6 months old) Brown Norway rats. The ligands stimulated Leydig cell T production significantly, and equivalently, in cells of both ages, an effect that was significantly inhibited by the specific TSPO inhibitor 5-androsten-3,17,19-triol (19-Atriol). Additionally, we examined the in vivo effects of administering FGIN-1-27 to young and aged rats. In both cases, serum T levels increased significantly, consistent with the in vitro results. Indeed, serum T levels in aged rats administered FGIN-1-27 were equivalent to T levels in the serum of control young rats. Taken together, these results indicate that although there are reduced amounts of TSPO in aged Leydig cells, its direct activation is able to increase T production. We suggest that this approach might serve as a therapeutic means to increase steroid levels in vivo in cases of primary hypogonadism.

Abstract
OBJECTIVE To examine whether there are latent trajectory classes in response to treatment and whether they moderate the effects of medication versus psychotherapy. METHOD Data come from a 1-year randomized controlled trial of 267 low-income, young (M = 29 years), minority (44% Black, 50% Latina, 6% White) women with current major depression randomized to antidepressants, cognitive-behavioral therapy (CBT), or referral to community mental health services. Growth mixture modeling was used to determine whether there were differential effects of medication versus CBT. Depression was measured via the Hamilton Depression Rating Scale (Hamilton, 1960). RESULTS We identified 2 latent trajectory classes. The first was characterized by severe depression at baseline. At 6 months, mean depression scores for the medication and CBT groups in this class were 13.9 and 14.9, respectively (difference not significant). At 12 months, mean depression scores were 16.4 and 11.0, respectively (p for difference = .04). The second class was characterized by moderate depression and anxiety at baseline. At 6 months, mean depression scores for the medication and CBT groups were 4.4 and 6.8, respectively (p for difference = .03). At 12 months, the mean depression scores were 7.1 and 7.8, respectively, and the difference was no longer significant. CONCLUSIONS Among depressed women with moderate baseline depression and anxiety, medication was superior to CBT at 6 months, but the difference was not sustained at 1 year. Among women with severe depression, there was no significant treatment group difference at 6 months, but CBT was superior to medication at 1 year.

Abstract
Few studies have examined the relationship between low-income, traumatized women and their health care providers. In this study we interviewed 23 women from primary care and social service settings for the underserved about trauma, attachment, psychiatric symptoms, and reports of their interactions with primary care providers. Nearly all reported trauma exposure, and 17% had current posttraumatic stress disorder. About half were categorized as Unresolved with regard to attachment state of mind. Analyses of a health experiences interview showed that women with Unresolved attachment reported significantly more negative interactions with providers. Attachment may play a role in the relationship between trauma and health care interactions with providers, indicating the need for further study of this relationship and suggesting intervention strategies to help both parties contribute to a more collaborative process.

Abstract
The nonlinear elasticity of thin supported membranes assembled from length purified single-wall carbon nanotubes is analyzed through the wrinkling instability that develops under uniaxial compression. In contrast with thin polymer films, pristine nanotube membranes exhibit strong softening under finite strain associated with bond slip and network fracture. We model the response as a shift in percolation threshold generated by strain-induced nanotube alignment in accordance with theoretical predictions.

Abstract
Introduction Multimodal MRI may be an effective tool for selecting suitable acute ischaemic stroke patients for thrombolysis, reducing the risk of haemorrhage. In this study, we demonstrated the usefulness of our central alerting system to reduce door-to-needle time for thrombolysis following MRI. This system allowed timely intervention and reduced the rate of symptomatic haemorrhage. Methods We reviewed the records of 73 patients with hyperacute ischaemic stroke who received intravenous (IV) tissue plasminogen activator (t-PA) between January 2006 and December 2007 following the adoption of a central stroke alerting system in our hospital. Results Of the 73 patients who received IV t-PA, 44 were based on CT and 29 on MRI findings. The door-to-needle time was 10 minutes longer for the MRI group (49.9±23.2 min) compared to the CT group (39.6±19.7 min) but it was still within the recommended 60 minutes time frame. On the other hand, the rate of symptomatic haemorrhage was lower, though insignificantly, in the MRI group (0%) compared to the CT group (13.6%) (p=0.08). Conclusions In this study, we demonstrated that the combination of diagnostic MRI and a central alerting system might reduce the rate of symptomatic haemorrhage without compromising the door-to-needle time.

Abstract
Increasingly, contemporary mental health services research projects aim to combine qualitative and quantitative components. Yet researchers often lack theoretical and practical guidance for undertaking such studies. In September 2006 the authors convened under the auspices of the National Institute of Mental Health at a working conference, "Mixed Methods in Community-Based Mental Health Services Research." This meeting provided the opportunity for participants to share their experiences in conducting mixed-methods research, to critically consider problems they had encountered and their solutions, and to develop guiding principles for others conducting similar research. The authors' discussions, which are described in this article, emphasize that the problems encountered by mixed-methods research teams are rarely simple misunderstandings but often reflect epistemological differences that are overlooked in the study planning phases. Failure to acknowledge these different worldviews may result in significant tensions between members of the study team, use of qualitative methods that are insufficient or inappropriate for a particular research question, or serious conflicts when team members belatedly discover they are interpreting key concepts -- or each other's research techniques -- differently. The authors conclude that ongoing communication is the organizing principle for robust and effective mixed-methods research. Among the recommendations for preventing problems are collaboration between quantitative and qualitative researchers during the study design phase; open acknowledgement of the philosophical approaches brought to the study by various team members; and because not all challenges can be anticipated, a shared willingness to negotiate emerging problems.

Abstract
When two thin soft elastomeric films are separated from each other, an elastic instability develops at the interface. Although similar instability develops for the case of a soft film separating from a rigid adherent, there are important differences in the two cases. For the single-film case, the wavelength of instability is independent of any material properties of the system, and it scales only with thickness of the film. For the two-film case, a co-operative instability mode develops, which is a non-linear function of the thicknesses and the elastic moduli of both films. We investigate the development of such instability by energy minimization procedures. Understanding the nature of this instability is important, as it affects the adhesive compliance of the system and thus the energy release rate in the debonding of soft interfaces.

Abstract
The occurrence of dental caries is mainly associated with oral pathogens, especially cariogenic Streptococcus mutans. Preliminary antibacterial screening revealed that the extract of Myristica fragrans, widely cultivated for the spice and flavor of foods, possessed strong inhibitory activity against S. mutans. The anticariogenic compound was successfully isolated from the methanol extract of M. fragrans by repeated silica gel chromatography, and its structure was identified as macelignan by instrumental analysis using 1D-NMR, 2D-NMR and EI-MS. The minimum inhibitory concentration (MIC) of macelignan against S. mutans was 3.9 microg/ml, which was much lower than those of other natural anticariogenic agents such as 15.6 microg/ml of sanguinarine, 250 microg/ml of eucalyptol, 500 microg/ml of menthol and thymol, and 1000 microg/ml of methyl salicylate. Macelignan also possessed preferential activity against other oral microorganisms such as Streptococcus sobrinus, Streptococcus salivarius, Streptococcus sanguis, Lactobacillus acidophilus and Lactobacillus casei in the MIC range of 2-31.3 microg/ml. In particular, the bactericidal test showed that macelignan, at a concentration of 20 microg/ml, completely inactivated S. mutans in 1 min. The specific activity and fast-effectiveness of macelignan against oral bacteria strongly suggest that it could be employed as a natural antibacterial agent in functional foods or oral care products.

Abstract
The health-related quality of life (HRQL) impact of depression for low-income young African-American women has not been quantified. Baseline scores on a generic HRQL measure, the SF-36, from a randomized controlled trial of depression treatments were used as a basis for describing the HRQL of depressed (n = 124) and non-depressed (n = 44) low-income African-American young women. Results were compared to U.S. normative values for well adults and for depressed adults. Relationship between SF-36 scores and demographic variables were examined, and SF-36 scores were compared for those with depression only and those with comorbid anxiety. SF-36 scores were lower for all eight subscales relative to the U.S. norms (p < 0.05) and lower on two subscales relative to a general U.S. depressed sample (p < 0.05). Higher age and higher number of children was associated with poorer scores. Comorbid anxiety was present in 66% of the depressed sample; all SF-36 scores for the sample with comorbid anxiety were significantly lower than scores for subjects with depression alone. Results indicate the substantial HRQL impact of depression among low-income young African-American women with depression.

Abstract
BACKGROUND Few clinical trials have evaluated interventions for major depressive disorder in samples of low-income minority women, and little is known about the cost-effectiveness of depression interventions for this population. OBJECTIVE To evaluate the cost-effectiveness of pharmacotherapy or cognitive behavior therapy (CBT) compared with community referral for major depression in low-income minority women. DESIGN, SETTING, AND PARTICIPANTS A randomized clinical trial was conducted in 267 women with current major depression. INTERVENTIONS Participants were randomly assigned to pharmacotherapy (paroxetine hydrochloride or bupropion hydrochloride) (n = 88), CBT (n = 90), or community referral (n = 89). MAIN OUTCOME MEASURES The main outcomes were intervention and health care costs, depression-free days, and quality-adjusted life years based on Hamilton Depression Rating Scale scores and Medical Outcomes Study 36-Item Short-Form Health Survey summary scores for 12 months. Cost-effectiveness ratios were estimated to compare incremental patient outcomes with incremental costs for pharmacotherapy relative to community referral and for CBT relative to community referral. RESULTS Compared with the community referral group, the pharmacotherapy group had significantly lower adjusted mean Hamilton Depression Rating Scale scores from the 3rd month through the 10th month (P = .04 to P<.001) of the study, and the CBT group had significantly lower adjusted mean scores from the 5th month through the 10th month (P = .03 to P = .049). There were significantly more depression-free days in the pharmacotherapy group (mean, 39.7; 95% confidence interval, 12.9-66.5) and the CBT group (mean, 25.80; 95% confidence interval, 0.04-51.50) than in the community referral group. The cost per additional depression-free day was USD 24.65 for pharmacotherapy and USD 27.04 for CBT compared with community referral. CONCLUSIONS Effective treatment for depression in low-income minority women reduces depressive symptoms but increases costs compared with community referral. The pharmacotherapy and CBT interventions were cost-effective relative to community referral for the health care system.

Abstract
We present a new search for H0V production, where H0 is a scalar Higgs boson decaying into bb with branching ratio beta, and V is a Z0 boson decaying into e+e-, mu+mu-, or nunu. This search is then combined with previous searches for H0V where V is a W+/- boson or a hadronically decaying Z0. The data sample consists of 106 +/- 4 pb(-1) of pp collisions at square root of s = 1.8 TeV accumulated by the Collider Detector at Fermilab. Observing no evidence of a signal, we set 95% Bayesian credibility level upper limits on sigma(pp --> H0V) x beta. For H0 masses of 90, 110, and 130 GeV/c2, the limits are 7.8, 7.2, and 6.6 pb, respectively.

Abstract
We report on a search for anomalous kinematics of tt dilepton events in pp collisions at square root of s=1.96 TeV using 193 pb(-1) of data collected with the CDF II detector. We developed a new a priori technique designed to isolate the subset in a data sample revealing the largest deviation from standard model (SM) expectations and to quantify the significance of this departure. In the four-variable space considered, no particular subset shows a significant discrepancy, and we find that the probability of obtaining a data sample less consistent with the SM than what is observed is 1.0%-4.5%.

Abstract
We report a measurement of the rate of prompt diphoton production in pp collisions at square root of s=1.96 TeV using a data sample of 207 pb(-1) collected with the upgraded Collider Detector at Fermilab. The background from nonprompt sources is determined using a statistical method based on differences in the electromagnetic showers. The cross section is measured as a function of the diphoton mass, the transverse momentum of the diphoton system, and the azimuthal angle between the two photons and is found to be consistent with perturbative QCD predictions.

Abstract
We present a measurement of the W(+)W(-) production cross section using 184 pb(-1) of p(p) collisions at a center-of-mass energy of 1.96 TeV collected with the Collider Detector at Fermilab. Using the dilepton decay channel W(+)W(-)-->l(+)nul(-), where the charged leptons can be either electrons or muons, we find 17 candidate events compared to an expected background of 5.0(+2.2)(-0.8) events. The resulting W(+)W(-) production cross-section measurement of sigma(pp-->W(+)W(-))=14.6(+5.8)(-5.1)(stat)(+1.8)(-3.0)(syst) +/- 0.9(lum) pb agrees well with the standard model expectation.

Abstract
We report the first largely model independent measurement of charged particle multiplicities in quark and gluon jets, Nq and Ng, produced at the Fermilab Tevatron in pp collisions with a center-of-mass energy of 1.8 TeV and recorded by the Collider Detector at Fermilab. The measurements are made for jets with average energies of 41 and 53 GeV by counting charged particle tracks in cones with opening angles of theta(c) = 0.28, 0.36, and 0.47 rad around the jet axis. The corresponding jet hardness Q = Ejet theta c varies in the range from 12 to 25 GeV. At Q = 19.2 GeV, the ratio of multiplicities r = Ng/Nq is found to be 1.64+/-0.17, where statistical and systematic uncertainties are added in quadrature. The results are in agreement with resummed perturbative QCD calculations.

Abstract
We present a measurement of relative partial widths and decay rate CP asymmetries in K-K+ and pi(-)pi(+) decays of D0 mesons produced in pp collisions at sqrt[s]=1.96 TeV. We use a sample of 2x10(5) D(*+)-->D0pi(+) (and charge conjugate) decays with the D0 decaying to K-pi(+), K-K+, and pi(-)pi(+), corresponding to 123 pb(-1) of data collected by the Collider Detector at Fermilab II experiment at the Fermilab Tevatron collider. No significant direct CP violation is observed. We measure Gamma(D0-->K-K+)/Gamma(D0-->K-pi(+))=0.0992+/-0.0011+/-0.0012, Gamma(D0-->pi(-)pi(+))/Gamma(D0-->K-pi(+))=0.035 94+/-0.000 54+/-0.000 40, A(CP)(K-K+)=(2.0+/-1.2+/-0.6)%, and A(CP)(pi(-)pi(+))=(1.0+/-1.3+/-0.6)%, where, in all cases, the first uncertainty is statistical and the second is systematic.

Abstract
We present measurements of the lifetimes and polarization amplitudes for B(0)(s)-->J/psiphi and B(0)(d)-->J/psiK(*0) decays. Lifetimes of the heavy and light mass eigenstates in the B(0)(s) system are separately measured for the first time by determining the relative contributions of amplitudes with definite CP as a function of the decay time. Using 203+/-15 B(0)(s) decays we obtain tau(L) = (1.05(+0.16)(-0.13) +/- 0.02) ps and tau(H) = (2.07(+0.58)(-0.46) +/- 0.03) ps. Expressed in terms of the difference DeltaGamma(s) and average Gamma(s), of the decay rates of the two eigenstates, the results are DeltaGamma(s)/Gamma(s) = (65(+25)(-33) +/- 1)% and DeltaGamma(s) = (0.47(+0.19)(-0.24) +/- 0.01) ps(-1).

Abstract
We present a search for excited and exotic electrons (e(*)) decaying to an electron and a photon, both with high transverse momentum. We use 202 pb(-1) of data collected in pp collisions at sqrt[s] = 1.96 TeV with the Collider Detector at Fermilab II detector. No signal above standard model expectation is seen for associated ee(*) production. We discuss the e(*) sensitivity in the parameter space of the excited electron mass M(e(*)) and the compositeness energy scale Lambda. In the contact interaction model, we exclude 132 GeV/c(2)<M(e(*))<879 GeV/c(2) for Lambda = M(e(*)) at 95% confidence level (C.L.). In the gauge-mediated model, we exclude 126 GeV/c(2) < M(e(*)) < 430 GeV/c(2) at 95% C.L. for the phenomenological coupling f/Lambda approximately 10(-2) GeV-1.

Abstract
We report the first measurements of inclusive W and Z cross sections times leptonic branching ratios for pp collisions at square root[s]=1.96 TeV, based on their decays to electrons and muons. The data correspond to an integrated luminosity of 72 pb(-1) recorded with the CDF detector at the Fermilab Tevatron. We test e-mu universality in W decays, and we measure the ratio of leptonic W and Z rates from which the leptonic branching fraction B(W-->lnu) can be extracted as well as an indirect value for the total width of the W and the Cabibbo-Kobayashi-Maskawa matrix element, |V(cs)|.

Abstract
The standard model predictions for Wgamma and Zgamma production are tested using an integrated luminosity of 200 pb(-1) of pp collision data collected at the Collider Detector at Fermilab. The cross sections are measured by selecting leptonic decays of the W and Z bosons, and photons with transverse energy ET>7 GeV that are well separated from leptons. The production cross sections and kinematic distributions for the Wgamma and Zgamma data are compared to SM predictions.

Abstract
To adapt to different environmental conditions between poikilothermic and homeothermic hosts, the plerocercoid of Spirometra erinacei (sparganum) might express a variety of biologically active molecules. We have identified a 78 kDa glucose-regulated protein of the sparganum (SpGrp78) by differential display of mRNA, employing RNAs each from sparganum adjusted at 9 degrees C and 37 degrees C. A full-length cDNA of 2148 bp encodes for a protein of 651 amino acids with a predicted molecular mass of 71 610 Da and shares molecular characteristics with heat-shock protein 70, including a putative ATP binding site, signal peptide cleavage site and endoplasmic reticulum retention signal. Phylogenetic analysis revealed that SpGrp78 was mostly related to those of Echinococcus multilocularis and E. granulosus. Expression of SpGrp78 mRNA increased approximately 7-fold by inhibition of glycosylation by tunicamycin, 2-fold by temperature-shift from 9 degrees C to 37 degrees C and slightly by pH-shift to 4.0 or 5.5. These results suggested that induction of SpGrp78 mRNA is related to the functional role of SpGrp78 as a molecular chaperone when the parasite adapts to a new host environment.

Abstract
We present the results of a search for doubly charged Higgs bosons (H+/-+/-) decaying to dileptons (ll(')) using approximately 240 pb(-1) of pp collision data collected by the CDF II experiment at the Fermilab Tevatron. In our search region, given by same-sign ll(') mass m(ll('))>80 GeV/c(2) (100 GeV/c(2) for ee channel), we observe no evidence for H+/-+/- production. We set limits on sigma(pp -->H++H---->l(+)l('+)l(-)l('-)) as a function of the mass of the H+/-+/- and the chirality of its couplings. Assuming exclusive same-sign dilepton decays, we derive lower mass limits on H(+/-+/-)(L) of 133, 136, and 115 GeV/c(2) in the ee, mumu, and emu channels, respectively, and a lower mass limit of 113 GeV/c(2) on H(+/-+/-)(R) in the mumu channel, all at the 95% confidence level.

Abstract
Acephalic cysticercus (Ac), a rarely developed multilobulated and nonencysted form of larvalTaenia, causes hydrocephalus or adhesive arachnoiditis in the ventricles and subarachnoidal space that often lead to fatal outcome in affected patients. Ac has been proposed to originate fromT. soliumon the basis of morphological features, while no molecular data supporting the presumption have been available. In the present study, we investigated the immunological properties as well as molecular characteristics of Ac that was obtained surgically from 6 patients. Immunoblotting of the cyst fluid from Ac samples demonstrated the constitutive expression of aT. soliummetacestode (TsM) 10 kDa protein. Specific antibodies against the truncated 10 kDa protein, which appears to be species specific for TsM cysticercosis, were detected in both serum and cerebrospinal fluid samples of Ac patients. Nucleotide sequences of mitochondrial cytochromecoxidase subunit I (COI) and NADH dehydrogenase subunit 1 (ND1) genes of Ac were almost identical to those ofT. soliumbut differed substantially from those of the otherTaeniaspecies. In phylogenetic analysis, Ac clustered withT. soliumin a well-supported clade. Our results strongly suggest that Ac may have originated fromT. solium.

Abstract
We report a measurement of the tt production cross section using dilepton events with jets and missing transverse energy in pp collisions at a center-of-mass energy of 1.96 TeV. Using a 197+/-12 pb(-1) data sample recorded by the upgraded Collider Detector at Fermilab, we use two complementary techniques to select candidate events. We compare the number of observed events and selected kinematical distributions with the predictions of the standard model and find good agreement. The combined result of the two techniques yields a tt production cross section of 7.0(+2.4)(-2.1)(stat)+1.6-1.1(syst)+/-0.4(lum) pb.

Abstract
We report results from a study of events with a double-Pomeron exchange topology produced in p p collisions at sqrt[s]=1800 GeV. The events are characterized by a leading antiproton and a large rapidity gap on the outgoing proton side. We find that the differential production cross section agrees in shape with predictions based on Regge theory and factorization, and that the ratio of double-Pomeron exchange to single diffractive production rates is relatively unsuppressed as compared to the O(10) suppression factor previously measured in single diffractive production.

Abstract
We report the observation of a narrow state decaying into J/psipi+pi- and produced in 220 pb(-1) of p p-bar collisions at =1.96 Tesqaure root of sV in the CDF II experiment. We observe 730+/-90 decays. The mass is measured to be 3871.3+/-0.7(stat)+/-0.4(syst) MeV/c2, with an observed width consistent with the detector resolution. This is in agreement with the recent observation by the Belle Collaboration of the X(3872) meson.

Abstract
We report on a search for anomalous production of events with at least two charged, isolated, like-sign leptons, each with pT > 11 GeV/c using a 107 pb(-1) sample of 1.8 TeV pp collisions collected by the CDF detector. We define a signal region containing low background from standard model processes. To avoid bias, we fix the final cuts before examining the event yield in the signal region using control regions to test the Monte Carlo predictions. We observe no events in the signal region, consistent with an expectation of 0.63(+0.84)(-0.07) events. We present 95% confidence level limits on new physics processes in both a signature-based context as well as within a representative minimal supergravity (tanbeta = 3) model.
