Abstract
Background: Asynchronous telepsychiatry (ATP) consultations are a novel form of psychiatric consultation. Studies comparing patient and provider satisfaction for ATP with that for synchronous telepsychiatry (STP) do not exist. Methods: This mixed-methods study is a secondary analysis of patients' and primary care providers' (PCPs) satisfaction from a randomized clinical trial of ATP compared with STP. Patients and their PCPs completed satisfaction surveys, and provided unstructured feedback about their experiences with either ATP or STP. Differences in patient satisfaction were assessed using mixed-effects logistic regression models, and the qualitative data were analyzed using thematic analysis with an inductive coding framework. Results: Patient satisfaction overall was high with 84% and 97% of respondents at 6 months reported being somewhat or completely satisfied with ATP and STP, respectively. Patients in the STP group were more likely to report being completely satisfied, to recommend the program to a friend, and to report being comfortable with their care compared with ATP (all p < 0.05). However, there was no difference between the patients in ATP and STP in perceived change in clinical outcomes (p = 0.51). The PCP quantitative data were small, and thus only summarized descriptively. Conclusions: Patients expressed their overall satisfaction with both STP and ATP. Patients in ATP reported more concerns about the process, likely because feedback after ATP was slower than that after STP consultations. PCPs had no apparent preference for STP or ATP, and reported implementing the psychiatrists' recommendations for both groups when such recommendations were made, which supports our previous findings.

Abstract
BACKGROUND The epidemiology of mental health disorders has important theoretical and practical implications for health care service and planning. The recent increase in big data storage and subsequent development of analytical tools suggest that mining search databases may yield important trends on mental health, which can be used to support existing population health studies. OBJECTIVE This study aimed to map depression search intent in the United States based on internet-based mental health queries. METHODS Weekly data on mental health searches were extracted from Google Trends for an 11-year period (2010-2021) and separated by US state for the following terms: "feeling sad," "depressed," "depression," "empty," "insomnia," "fatigue," "guilty," "feeling guilty," and "suicide." Multivariable regression models were created based on geographic and environmental factors and normalized to the following control terms: "sports," "news," "google," "youtube," "facebook," and "netflix." Heat maps of population depression were generated based on search intent. RESULTS Depression search intent grew 67% from January 2010 to March 2021. Depression search intent showed significant seasonal patterns with peak intensity during winter (adjusted P<.001) and early spring months (adjusted P<.001), relative to summer months. Geographic location correlated with depression search intent with states in the Northeast (adjusted P=.01) having higher search intent than states in the South. CONCLUSIONS The trends extrapolated from Google Trends successfully correlate with known risk factors for depression, such as seasonality and increasing latitude. These findings suggest that Google Trends may be a valid novel epidemiological tool to map depression prevalence in the United States.

Abstract
OBJECTIVE Hyponatremia is the most common electrolyte imbalance encountered in clinical practice and is associated with negative healthcare outcomes and cost. SIADH is thought to account for one third of all hyponatremia cases and is typically an insidious process. Psychotropic medications are commonly implicated in the etiology of drug induced SIADH. There is limited guidance for clinicians on management of psychotropic-induced SIADH. METHODS After an extensive review of the existing literature, clinical-educators from the Association of Medicine and Psychiatry developed expert consensus recommendations for management of psychotropic-induced SIADH. A risk score was proposed based on risk factors for SIADH to guide clinical decision-making. RESULTS SSRIs, SNRIs, antipsychotics, carbamazepine, and oxcarbazepine have moderate to high level of evidence demonstrating their association with SIADH. Evaluation for an avoidance of medications that cause hyponatremia is particularly important. Substitution with medication that is less likely to cause SIADH should be considered when appropriate. We propose an algorithmic approach to monitoring hyponatremia with SIADH and corresponding treatment depending on symptom severity. CONCLUSIONS The proposed algorithm can help clinicians in determining whether psychotropic medication should be stopped, reduced or substituted where SIADH is suspected with recommendations for sodium (Na+) monitoring. These recommendations preserve a role for clinical judgment in the management of hyponatremia with consideration of the risks and benefits, which may be particularly relevant for complex patients that present with medical and psychiatric comorbidities. Further studies are needed to determine whether baseline and serial Na+ monitoring reduces morbidity and mortality.

Abstract
Objective: To compare clinical recommendations given by psychiatrists and the adherence to these recommendations by primary care physicians (PCP) following consultations conducted by asynchronous telepsychiatry (ATP) and synchronous telepsychiatry (STP). Materials and Methods: ATP and STP consultations were compared using intermediate data from a randomized clinical trial with adult participant enrollment between April 2014 and December 2017. In both study arms, PCPs received written recommendations from the psychiatrist after each encounter. Independent clinicians reviewed PCP documentation to measure adherence to those recommendations in the 6 months following the baseline consultation. Results: Medical records were reviewed for 645 psychiatrists' consult recommendations; 344 from 61 ATP consultations and 301 from 62 STP consultations. Of those recommendations, 191 (56%) and 173 (58%) were rated fully adherent by two independent raters for ATP and STP, respectively. In a multilevel ordinal logistic regression model adjusted for recommendation type and recommended implementation timing, there was no statistically significant difference in adherence to recommendations for ATP compared with STP (adjusted odds ratio = 0.91, 95% confidence interval = 0.51-1.62). The profiles of recommendation type were comparable between ATP and STP. Conclusions: This is the first PCP adherence study comparing two forms of telemedicine. Although we did not find evidence of a difference between ATP and STP; this study supports the feasibility and acceptability of ATP and STP for the provision of collaborative psychiatric care.

Abstract
BACKGROUND Asynchronous telepsychiatry (ATP; delayed-time) consultations are a novel form of psychiatric consultation in primary care settings. Longitudinal studies comparing clinical outcomes for ATP with synchronous telepsychiatry (STP) are lacking. OBJECTIVE This study aims to determine the effectiveness of ATP in improving clinical outcomes in English- and Spanish-speaking primary care patients compared with STP, the telepsychiatry usual care method. METHODS Overall, 36 primary care physicians from 3 primary care clinics referred a heterogeneous sample of 401 treatment-seeking adult patients with nonurgent psychiatric disorders. A total of 184 (94 ATP and 90 STP) English- and Spanish-speaking participants (36/184, 19.6% Hispanic) were enrolled and randomized, and 160 (80 ATP and 80 STP) of them completed baseline evaluations. Patients were treated by their primary care physicians using a collaborative care model in consultation with the University of California Davis Health telepsychiatrists, who consulted with patients every 6 months for up to 2 years using ATP or STP. Primary outcomes (the clinician-rated Clinical Global Impressions [CGI] scale and the Global Assessment of Functioning [GAF]) and secondary outcomes (patients' self-reported physical and mental health and depression) outcomes were assessed every 6 months. RESULTS For clinician-rated primary outcomes, ATP did not promote greater improvement than STP at 6-month follow-up (ATP vs STP, adjusted difference in follow-up at 6 months vs baseline differences for CGI: 0.2, 95% CI -0.2 to 0.6; P=.28; and GAF: -0.6, 95% CI -3.1 to 1.9; P=.66) or 12-month follow-up (ATP vs STP, adjusted difference in follow-up at 12 months vs baseline differences for CGI: 0.4, 95% CI -0.04 to 0.8; P=.07; and GAF: -0.5, 95% CI -3.3 to 2.2; P=.70), but patients in both arms had statistically and clinically significant improvements in both outcomes. There were no significant differences in improvement from baseline between ATP and STP on any patient self-reported ratings at any follow-up (all P values were between .17 and .96). Dropout rates were higher than predicted but similar between the 2 arms. Of those with baseline visits, 46.8% (75/160) did not have a follow-up at 1 year, and 72.7% (107/147) did not have a follow-up at 2 years. No serious adverse events were associated with the intervention. CONCLUSIONS This is the first longitudinal study to demonstrate that ATP can improve clinical outcomes in English- and Spanish-speaking primary care patients. Although we did not find evidence that ATP is superior to STP in improving clinical outcomes, it is potentially a key part of stepped mental health interventions available in primary care. ATP presents a possible solution to the workforce shortage of psychiatrists and a strategy for improving existing systems of care.

Abstract
Background Lying on the floor for a long period of time has been described as a critical determinant of prognosis following a fall. In addition to fall-related injuries due to the trauma itself, prolonged immobilization on the floor results in a wide range of comorbidities and may double the risk of death in elderly. Thus, reducing the length of Time On the Ground (TOG) in fallers seems crucial in vulnerable individuals with cognitive disorders who cannot get up independently. Objective This study aimed to examine the effect of a new technology called SafelyYou Guardian (SYG) on early post-fall care including reduction of Time Until staff Assistance (TUA) and TOG. Methods SYG uses continuous video monitoring, artificial intelligence, secure networks, and customized computer applications to detect and notify caregivers about falls in real time while providing immediate access to video footage of falls. The present observational study was conducted in 6 California memory care facilities where SYG was installed in bedrooms of consenting residents and families. Fall events were video recorded over 10 months. During the baseline installation period (November 2017 to December 2017), SYG video captures of falls were not provided on a regular basis to facility staff review. During a second period (January 2018 to April 2018), video captures were delivered to facility staff on a regular weekly basis. During the third period (May 2018 to August 2018), real-time notification (RTN) of any fall was provided to facility staff. Two digital markers (TUA, TOG) were automatically measured and compared between the baseline period (first 2 months) and the RTN period (last 4 months). The total number of falls including those happening outside of the bedroom (such as common areas and bathrooms) was separately reported by facility staff. Results A total of 436 falls were recorded in 66 participants suffering from Alzheimer disease or related dementias (mean age 87 years; minimum 65, maximum 104 years). Over 80% of the falls happened in bedrooms, with two-thirds occurring overnight (8 PM to 8 AM). While only 8.1% (22/272) of falls were scored as moderate or severe, fallers were not able to stand up alone in 97.6% (247/253) of the cases. Reductions of 28.3 (CI 19.6-37.1) minutes in TUA and 29.6 (CI 20.3-38.9) minutes in TOG were observed between the baseline and RTN periods. The proportion of fallers with TOG >1 hour fell from 31% (8/26; baseline) to zero events (RTN period). During the RTN period, 76.6% (108/141) of fallers received human staff assistance in less than 10 minutes, and 55.3% (78/141) of them spent less than 10 minutes on the ground. Conclusions SYG technology is capable of reducing TOG and TUA while efficiently covering the area (bedroom) and time zone (nighttime) that are at highest risk. After 6 months of SYG monitoring, TOG was reduced by a factor of 3. The drastic reduction of TOG is likely to decrease secondary comorbid complications, improve post-fall prognosis, and reduce health care costs.

Abstract
OBJECTIVE Diabetic nephropathy (DN) is one of the most representative diabetic microangiopathy complications. So far, there have been no satisfactory therapeutic strategies, and the injection of stem cells provides a target for DN therapy. PATIENTS AND METHODS Urine-derived stem cells (USCs) were obtained from 9 healthy men. 24 mice were randomly and equally divided into control group, DN model group, DN+hUSC group (treated with USCs for 3 times). Hematoxylin-eosin (HE) and Masson staining were used to detect histological changes of kidney injury. Creatinine and blood urea nitrogen (BUN) were measured to assess renal function. Besides, myofibroblast accumulation, macrophage infiltration, cell proliferation, and oxidative stress were detected by immunohistochemical analysis. RESULTS Compared with DN model group, DN+hUSC group showed lower function loss, cell infiltration, and oxidative stress, as well as less renal fibrosis, histological damage, and cell proliferation. CONCLUSIONS USC can alleviate inflammation and oxidative stress, reduce renal interstitial fibrosis, improve renal tissue structure and protect renal function through paracrine effect.

Abstract
Objective: Asynchronous telepsychiatry (ATP) is an integrative model of behavioral health service delivery that is applicable in a variety of settings and populations, particularly consultation in primary care. This article outlines the development of a training model for ATP clinician skills. Methods: Clinical and procedural training for ATP clinicians (n = 5) was provided by master's-level, clinical mental health providers developed by three experienced telepsychiatrists (P.Y. D.H., and J.S) and supervised by a tele-psychiatrist (PY, GX, DL) through seminar, case supervision, and case discussions. A training manual and one-on-one sessions were employed for initial training. Unstructured expert discussion and feedback sessions were conducted in the training phase of the study in year 1 and annually thereafter over the remaining 4 years of the study. The notes gathered during those sessions were synthesized into themes to gain a summary of the study telepsychiatrist training recommendations for ATP interviewers. Results: Expert feedback and discussion revealed three overarching themes of recommended skill sets for ATP interviewers: (1) comprehensive skills in brief psychiatric interviewing, (2) adequate knowledge base of behavioral health conditions and therapeutic techniques, and (3) clinical documentation, integrated care/consultation practices, and e-competency skill sets. The model of training and skill requirements from expert feedback sessions included these three skill sets. Technology training recommendations were also identified and included: (1) awareness of privacy/confidentiality for electronic data gathering, storage, management, and sharing; (2) technology troubleshooting; and (3) video filming/retrieval. Conclusions: We describe and provide a suggested training model for the use of ATP integrated behavioral health. The training needs for ATP clinicians were assessed on a limited convenience sample of experts and clinicians, and more rigorous studies of training for ATP and other technology-focused, behavioral health services are needed. Clinical Trials number: NCT03538860.

Abstract
PURPOSE To assess the longitudinal associations between maternal total bile acid (TBA) levels during early mid-pregnancy and the subsequent risk of gestational diabetes mellitus (GDM). METHODS In a prospective cohort study, pregnant women who were enrolled prior to gestational week 16 were followed until delivery. TBA levels were tested during weeks 14-18 of gestation. Using logistic regression, we analyzed the associations between quartiles of TBA and GDM based on a 75-g oral glucose tolerance test (OGTT) at 24-28 gestational weeks. RESULTS The GDM rate was 7.9% (114/1441). The mean TBA level was higher in women with GDM than in those without GDM (2.1 ± 2.0 vs 1.5 ± 1.0 µmol/L, P = 0.000). The highest TBA level quartile (2.1-10.7 µmol/L) had a 1.78-fold (95% CI 1.01, 3.14) increased risk of GDM compared with that of the lowest quartile (0.0-0.8 µmol/L) after adjusting for pre-pregnancy body mass index (BMI), gestational, age at TBA test and other confounders. High TBA levels were involved in the fasting glucose level rather than that at 1 h and 2 h after OGTT in all participants. CONCLUSIONS Pregnant women with higher serum TBA levels during early mid-pregnancy have a higher risk of developing GDM. TBA may be a new risk factor for GDM.

Abstract
Introduction: Research is increasing on asynchronous technologies used by specialist clinicians and primary care, including e-mail, text, e-consultation, and store-and-forward (asynchronous) options. Studies typically describe interventions and care outcomes rather than development of clinical skills for using technology. Methods: This article attempts to compare clinicians' approaches to, and skills for, asynchronous technologies versus in-person and synchronous (i.e., video) care. Literature from technology, health care, pedagogy, and business were searched from 2000 to 2019 for title words, including synchronous (e.g., video, telemental or behavioral health, telepsychiatry), asynchronous (e.g., app, e-consultation, e-mail, text, sensor in a wearable device), education, clinical, and consultation. Results: From a total of 4,812 potential references, two authors (D.M.H., J.T.) found 4,622 eligible for full text review and found 381 articles directly relevant to the concept areas in combination for full text review. However, exclusion criteria subtracted 305, leaving a total of 76 articles. While in-person and synchronous care are similar in many ways, the clinical approach to asynchronous care has many differences. As asynchronous technologies and models of care are feasible and effective, often for consultation, an outline of patient, primary care provider, and specialist clinician goals and skills are presented. Few studies specifically discuss skills or competencies for asynchronous care, but components from published clinical informatics, video, social media, and mobile health competencies were organized into Accreditation Council of Graduate Medical Education domains. Conclusions: Further implementation of science research is needed for asynchronous technology interventions, as well as clinician competencies using asynchronous technologies, to ensure optimal outcomes for patients in health care.

Abstract
Pancreatic ductal adenocarcinoma is a most deadly malignancy, with a 5-year survival rate of ~7%. Chemotherapy is the main treatment strategy of this disease. However, the high rate of resistance to chemotherapeutic agent contributes to poor prognosis. MicroRNAs are essential for the initiation, progression and chemoresistance of human malignancies. Previous studies have shown that miRNA-1285 participates in renal cell carcinoma and hepatocellular carcinoma. However, its roles in pancreatic ductal adenocarcinoma are poorly understood. In this study, we confirmed that miR-1285 was significantly down-regulated in gemcitabine-resistant pancreatic cancer cell lines by qRT-PCR. We found that miR-1285 suppressed cell proliferation as well as increased the sensitivity of PDAC cells to gemcitabine by CCK8 assays in vitro. Results from transwell assay indicated that miR-1285 inhibited pancreatic cancer cell migration and invasion. Experiments using different cell lines got identical results. All those results demonstrated that miR-1285 act as tumor suppressor of pancreatic cancer. To our knowledge, this study is the first to elucidate the function of miR-1285 in pancreatic cancer. Western blotting analysis verified that miR-1285 negatively regulated YAP1 protein level, together with EGFR and β-catenin. YAP1 is a known oncoprotein of pancreatic cancer. As silencing of YAP1 activity might be beneficial in cancer prevention and treatment, our results suggest that miR-1285 might serve as a novel therapeutic target for miRNA-based therapy in pancreatic cancer. Further research elucidating the exact mechanisms of miRNA-1285 function and the correlation between miR-1285 levels in tissues or serum and clinical characteristics of pancreatic cancer is needed later.

Abstract
OBJECTIVE Integrated behavioral healthcare models typically involve a range of consultation options for mental healthcare. Asynchronous telepsychiatry (ATP) consults may be an additional potential choice, so we are conducting a 5-year clinical trial comparing ATP with synchronous telepsychiatry (STP) consultations. METHODS Patients referred by primary care providers are randomly assigned to one of the two treatment groups, ATP or STP. Clinical outcome, satisfaction, and economic data are being collected from patients for 2 years at 6-month intervals. RESULTS Baseline characteristics for the first 158 patients and case examples of ATP are presented. CONCLUSION Implementing ATP in existing integrated behavioral healthcare models could make mental healthcare more efficient.

Abstract
OBJECTIVE The haematological and cardiac complications of clozapine have been well documented. Recent evidence from pharmacovigilance databases suggests that gastrointestinal (GI) complications are the leading cause of clozapine related deaths. This review aims to describe clinical features along with preventative and treatment options. METHOD A review of MEDLINE via PubMed searching for all articles published up to February of 2016. Inclusion criteria were articles that provided clinical or epidemiological information relating to the diagnosis, outcome, management or pathophysiology of clozapine related gastrointestinal disorders in humans. RESULTS Three large case series were identified with 104 cases, 20 of these reported clinical details. A further 52 cases reports were included. Median age was 40, with 79% being male, mean daily clozapine dose was 453 mg. Mortality was 38% with survivors being younger (39 vs. 42), on lower daily doses (400 mg vs. 532 mg), more likely to be female (32% vs. 6%). Four patients were re-challenged with clozapine following CIGH, two suffered a recurrence. CONCLUSION Risk factors for CIGH appear to be older age, male gender, patients in the first four months of treatment, co-prescription of constipating agents, higher daily dose of clozapine, and previous CIGH. Risk factors for death were older age and male gender. Patients receiving clozapine should be counselled about the dangers of constipation and to report new GI symptoms. Once severe CIGH has occurred clozapine should be halted and reviewed with bowel symptoms managed promptly. Re-challenging with clozapine may present substantial risks due to the severity of CIGH and a paucity of evidence. From the available evidence a treatment strategy has been proposed. Further prospective data regarding CIGH are needed to allow a better assessment of the scale of the problem with the development and testing of treatment strategies.

Abstract
Seventeen fresh lunates with stage III Kienböck's disease were scanned with micro-computed tomography. Four regions of interest were selected to measure trabecular parameters, which were compared with those from normal lunates. Within the three regions in the distal surface, there was more compact trabecular bone in the middle region when compared with the palmar and dorsal regions. In the central part, the trabeculae of the Kienböck's lunates were much thicker than those in normal lunates. The diameters of the palmar nutrient foramina of the Kienböck's lunates were significantly smaller than those in normal lunates. In affected lunates, the bony disruptions were mostly located in the palmar or dorsal areas, which were shown from trabecular bone structure analysis to be structurally weaker. This leads to separation of the distal part of the fractured bone, disruption of the blood supply, poor bone remodelling and proneness to secondary fracture and eventual collapse.

MATERIALS AND METHODS A literature search on Pubmed, Embase, and the Cochrane library was conducted according to the PRISMA guidelines, and a meta-analysis was performed to assess cancer-specific survival (CSS), overall survival (OS), recurrence-free survival (RFS), intravesical recurrence free survival (IVRFS) and surgery-related variations in estimated glomerular filtration rate (eGFR). RESULTS A total of 11 retrospective studies with 3963 patients who underwent either SU (n = 983; 24.8%) or RNU (n = 2980; 75.2%) were included. Although patients treated with SU were more likely to be diagnosed with favorable pathological features, the meta-analysis of unadjusted data revealed no significant difference between both groups in terms of CSS (HR 0.90, p = 0.33) and OS (HR 0.98, p = 0.93). Accordingly, the meta-analysis of adjusted data confirmed equivalent CSS (HR = 0.90, p = 0.47) between SU and RNU. Similarly, no significant difference was found in terms of RFS (HR 1.06, p = 0.72) and IVRFS (HR 1.35, p = 0.39). However, a significant decreased risk of impaired renal function was observed after SU when compared to RNU (mean eGFR difference = 9.32 ml/1.73 m2, p = 0.007). CONCLUSION Although adverse patient and tumor characteristics were not equally balanced between treatment arms, our systematic review and meta-analysis supports similar oncological outcomes between SU and RNU, with better preservation of renal function after SU. As such, SU should be preferably used as the first-line treatment for low-risk ureter tumors, while considered for selected cases of high-risk disease.

Abstract
Speckled (Spc), an X-ray-induced lethal mutant of Bombyx mori, exhibits a mosaic dark-brown-spotted larval epidermis in both sexes and egg-laying problems only in females. Here, we report the morphological characterization and molecular mapping of the Spc mutant. Morphological investigations revealed that the epidermal ultrastructure of the small, dark-brown spots was more dense than that of the white regions in both Spc/+ mutants and wild type, and that the lethality of the Spc/Spc mutants occurred during early embryogenesis. Furthermore, the ovarioles and ovipositor were disconnected in approximately 85.5% of Spc/+ females, a further 2.5% had a connection between the ovarioles and ovipositor that was too narrow to lay eggs. The remaining females showed a normal connection similar to that of the wild type. We successfully narrowed down the location of the Spc mutation to a region on chromosome 4 that was ∼1041 kb long. Gene-prediction analysis identified 25 candidate genes in this region. Chromosome structure analysis indicated that a ∼305 kb deletion was included in the mapping region. Temporal and spatial reverse transcription PCR (RT-PCR) analysis showed that several genes in the mapped region are associated with the Spc mutant. Although the genes responsible for the Spc mutation were not definitively identified, our results further the current understanding of the complex mechanism underlying the multiple morphological defects in Spc mutants.

Abstract
The metastatic spread of cancer cells to distant sites represents the major cause of cancer-related deaths in breast cancer patients, and lungs are one of the most common sites for metastatic colonization. Developing a physiologically relevant tissue culture model to mimic lung colonization of breast cancer is crucial for the investigation of the biology of cancer metastasis and evaluation of drug treatment efficacy. Here, we describe an ex vivo lung colonization assay for breast cancer using the native three-dimensional (3D) lung extracellular matrix. The native matrix was isolated from murine lungs using a decellularization technique, and the preservation of extracellular matrix (ECM) composition, integrity and mechanical properties was confirmed. We showed that metastatic MDA-MB 231 and 4T1 cells invaded and colonized in the decellularized lung matrix, whereas only a small mass of non-metastatic MCF7 cells survived under the same condition. Furthermore, knockdown of ZEB1, an epithelial-mesenchymal transition (EMT) inducer, significantly reduced invasion and colonization of MDA-MB 231 cells in the decellularized lung, suggesting an important role of EMT in breast cancer metastasis. We conclude that the decellularized lung retains the biophysical and biochemical properties of the lung ECM and provides a powerful tool to investigate the lung colonization of breast cancer.

Abstract
The large yellow croaker (Larimichthys crocea) is one of the largest marine net-cage cultured species in the oceans around China. In the present study, we isolated and characterized 13 polymorphic microsatellite markers from genomic libraries of L. crocea. Loci were screened for 10 wild specimens from 2 sites in southeast of China. All loci were polymorphic. The number of alleles per locus ranged from 2 to 21. The expected heterozygosity ranged from 0.233 to 0.838 and observed heterozygosity ranged from 0.527 to 0.935. Eleven loci were highly informative (polymorphic information content >0.5). Significant deviation from Hardy-Weinberg equilibrium was observed at 3 loci after Bonferroni's correction. The microsatellite loci may be valuable tools for studying the genetic diversity and genetic structure for conservation planning of the fish.

Abstract
Altered SERT and DAT availabilities during treatment with escitalopram were investigated with [(123)I]2β-carbomethoxy-3β-(4-iodophenyl)tropane (β-CIT) SPECT in a series of patients fulfilling the criteria for unipolar major depressive disorder (MDD). 27 patients (10m, 42±16y) with diagnosis of MDD were recruited for the study. All patients underwent neuropsychiatric testing for assessment of Hamilton Depression (HAM-D) and Beck Depression Inventory (BDI) scores. At baseline, [(123)I]β-CIT SPECT recordings were acquired 4h (SERT-weighted) and 20-24h p.i (DAT-weighted). Follow-up scans and neuropsychiatric testing were performed after six weeks of stable escitalopram medication. Voxel-wise parametric maps of specific/ non-specific ratios-1 (~BPND) were calculated. At baseline, DAT-weighted BPND was 5.06±0.81 in striatum and SERT-weighted BPND was 0.94±0.18 in thalamus. There were significant negative correlations with age for DAT in striatum (R=-0.60; p<0.01) and SERT in thalamus (R=-0.45; p<0.05). Under SSRI treatment there was an apparent 42% occupancy of SERT in thalamus (p<0.0001), whereas DAT availability increased significantly by 20% in striatum (p<0.001); higher apparent SERT occupancy in thalamus was associated with lesser DAT increase in striatum (R=-0.62; p<0.005). The low apparent SERT occupancy may be confounded by alterations in SERT expression during treatment. Thus, [(123)I]β-CIT SPECT revealed age-dependent declines in DAT and SERT availabilities in un-medicated MDD patients, comparable to that seen previously in healthy controls. At follow-up, the SSRI-evoked increase in DAT was less pronounced in the older patients, even though apparent SERT occupancy and clinical improvement were not age-dependent. Present findings may have implications for escitalopram dosage and side effect profile in younger MDD patients.

Abstract
UNLABELLED The aim of this study was to determine the response of advanced-stage non-small cell lung cancer (NSCLC) patients with or without EGFR mutations to platinum-based chemotherapy with or without gefitinib maintenance. Patients were treated with four cycles of platinum-based chemotherapy. Patients with wild-type EGFR were observed (group 1; n=15). EGFR mutation-positive patients were randomly assigned to observation (group 2; n=7) or gefitinib maintenance (group 3; n=7). The median patient age was 59 years. The 1-year progression-free survival rates in groups 1, 2, and 3 were 6.7%, 28.6%, and 57.1%, respectively (p = 0.049); the 1-year overall survival rates were 53.3%, 57.1 %, and 100%, respectively (p = 0.111). The results indicate that patients with advanced-stage NSCLC with EGFR mutations have a better response to chemotherapy followed by gefitinib than chemotherapy alone and a better response to chemotherapy than wild-type patients.

Abstract
Ten patients with metacarpophalangeal joint locking of the thumb were studied. Three of them underwent surgical release. During surgery, it was found that the radial sesamoid was seated in a cartilage defect on the volar aspect of the metacarpal head. It appeared that the defect was created by the proximal edge of sesamoid. When the abductor pollicis brevis and flexor pollicis brevis muscles were partially detached from their insertion at the base of the proximal phalanx, the locking could be successfully released. We hypothesize the mechanism of the metacarpophalangeal joint locking of the thumb in our cases was a hyperextension injury that displaced the radial sesamoid distally and radially. In turn, the sesamoid's pointed proximal edge wore a groove in the cartilage on the metacarpal head, and under abductor pollicis brevis and flexor pollicis brevis tension, the radial sesamoid was locked into the cartilage defect; thereby causing locking of the joint.

Abstract
The plant cell wall is an important factor for determining cell shape, function and response to the environment. Secondary cell walls, such as those found in xylem, are composed of cellulose, hemicelluloses and lignin and account for the bulk of plant biomass. The coordination between transcriptional regulation of synthesis for each polymer is complex and vital to cell function. A regulatory hierarchy of developmental switches has been proposed, although the full complement of regulators remains unknown. Here, we present a protein-DNA network between Arabidopsis transcription factors and secondary cell wall metabolic genes with gene expression regulated by a series of feed-forward loops. This model allowed us to develop and validate new hypotheses about secondary wall gene regulation under abiotic stress. Distinct stresses are able to perturb targeted genes to potentially promote functional adaptation. These interactions will serve as a foundation for understanding the regulation of a complex, integral plant component.

Abstract
Key insights into the behavior of materials can be gained by observing their structure as they undergo lattice distortion. Laser pulses on the femtosecond time scale can be used to induce disorder in a "pump-probe" experiment with the ensuing transients being probed stroboscopically with femtosecond pulses of visible light, x-rays, or electrons. Here we report three-dimensional imaging of the generation and subsequent evolution of coherent acoustic phonons on the picosecond time scale within a single gold nanocrystal by means of an x-ray free-electron laser, providing insights into the physics of this phenomenon. Our results allow comparison and confirmation of predictive models based on continuum elasticity theory and molecular dynamics simulations.

Abstract
OBJECTIVE To examine the feasibility and diagnostic reliability of asynchronous telepsychiatry (ATP) consultations in Spanish and ATP consultation with Spanish-to-English translation. SUBJECTS AND METHODS Twenty-four interviews of Spanish-speaking patients were videorecorded by a bilingual clinician who also collected patient history data and gave the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) to each patient. The ATP data (video of the interview and patient history) were forwarded for psychiatric consultation and a diagnostic assessment by the investigators. The ATP data were then examined separately by two Spanish-speaking psychiatrists, before being translated into English and then re-examined by two English-speaking psychiatrists. Agreement between the expert diagnoses of the investigators and the diagnoses from the Spanish consultations, the Spanish-to-English translated consultations, and the SCID-I results was assessed using kappa statistics. RESULTS We found acceptable levels of agreement for major diagnostic groupings among the Spanish- and English-speaking psychiatrists. Kappa values for diagnostic agreement between the expert and the translated consultations, the original language consultations, and the SCID-I were at least 0.52 (percentage agreement, 79%) and higher. CONCLUSIONS ATP consultations in Spanish, and those translated from Spanish to English, are feasible, and broad diagnostic reliability was achieved. The ATP process allows for rapid language translation. This approach could be useful across national boundaries and in numerous ethnic groups. Cross-language ATP may also offer significant benefits over the use of real-time interpreting services and has the potential to improve the quality of care by allowing for the addition of culturally relevant information.
