Isolation and identification of a male-produced aggregation-sex pheromone for the velvet longhorned beetle, Trichoferus campestris.
The velvet longhorned beetle, Trichoferus campestris (Faldermann) ("VLB"; Coleoptera: Cerambycidae), is native to eastern Asia where it infests and damages a wide range of deciduous and coniferous tree species, including orchard and timber species. Immature stages of VLB are transported to new countries via international commerce, and populations have established outside the native range of the species. Here, we show that identification of pheromones of invasive pest species can be expedited by knowledge of the semiochemistry of related taxa. Histological sectioning revealed subcuticular, male-specific prothoracic glands connected to pits in the cuticle, which, in related species, are diagnostic for production of male-produced aggregation-sex pheromones, usually characterized by 2,3-alkanediol/hydroxyketone structural motifs. However, in preliminary field bioassays, beetles were not attracted by any known cerambycid pheromones. Subsequently, we identified a novel variant of the hydroxyketone motif ("trichoferone") from headspace volatiles of males. In field bioassays, synthetic trichoferone was more attractive to both sexes of VLB than previously developed high-release-rate ethanol lures, and attraction was strongly female biased. This study demonstrated the utility of the prothoracic gland trait for predicting pheromone use in cerambycid species in the subfamily Cerambycinae, and that identification of pheromones of novel species can be expedited by knowledge of pheromones of related species. Trichoferone should prove to be a valuable tool for detection of VLB in regions where the beetle is or may become established

This fact sheet describes Japanese beetles and reviews damage symptoms, life cycle, monitoring, and management
Velvet Longhorned Beetle (Trichoferus campestris (Faldermann)
The velvet longhorned beetle is an invasive wood-boring pest that is native to Asia and Russia. It infests fruit, forest, and ornamental trees, as well as green and dry wood, such as timber and lumber. This fact sheet provides a description, and information on life history, plant hosts, injury symptoms, monitoring, and management

Research and assessment with LGBTQ+ persons
This Association for Lesbian, Gay, Bisexual, and Transgender Issues in Counseling (ALGBTIC) special issue is a culmination of 2 years of collective activities centered on increasing the focus and attention of assessment and research with the lesbian, gay, bisexual, transgender, gender expansive, and queer/questioning (LGBTGEQ+) communities. In response to identified gaps in the current assessment and research literatures related to counseling those within the LGBTGEQ+ communities, servant leader scholars representing ALGBTIC and the Association for Assessment and Research in Counseling (AARC) came together in a joint task force to create two sets of standards of care, for assessment and research, for use with these communities. Both sets of standards are included at the beginning of this special issue. Our hope is that these documents serve as a resource and reference for practicing counselors, counselor educators, and their students, for years to come.
In addition, this special issue contains eight other articles, informed by the ALGBTIC Standards of Care, exploring ways to understand, inform, or utilize assessment and research more deeply and in ways that are beneficial and supportive of the LGBTGEQ+ communities. Included are a variety of conceptual and research-based articles examining norm reference groups for commonly used assessments, a review of instruments created to measure LGBTGEQ+ affirmation and discrimination, best practices for assessment and evaluation, as well as articles exploring how research can be conducted in culturally sensitive and relevant ways to accurately represent the experiences of LGBTGEQ+ persons and communities. We hope you find the Standards of Care, as well as the additional articles synthesizing the Standards of Care contained in this special issue, to be relevant for your work and that each will provide you some takeaways for whatever your relationship with counseling, assessing, or researching LGBTGEQ+ persons

Serosurvey and diagnostic application of antibody titers to Aspergillus in avian species
A multiyear study was conducted using an enzyme-linked immunosorbent assay to measure antibody to address the application of the test to the diagnosis of aspergillosis in avian species. In general serostudies (n=1314), four avian groups (psittaciform, raptor, penguin, and zoo) were found to have samples with antibody reactivity. Penguin, raptor, and zoo groups were found to have higher levels of antibody to Aspergillus than the psittaciform group. Additional clinical information was collected on 303 cases, which resulted in the definition of presumptive normal, probable, and confirmed infection groups. Although the confirmed group was more likely to have antibody reactivity, the mean antibody index was not found to be significant between presumptive normal and probable or confirmed cases

Application of galactomannan analysis and protein electrophoresis in the diagnosis of aspergillosis in avian species
Previous studies support the possible application of galactomannan, a major antigen of Aspergillus sp., to aspergillosis diagnosis in avian and other animal species. An assay is commercially available for use with human serum and bronchoalveolar lavage fluid samples. In the current study, galactomannan results from plasma samples were compared between birds with histologically confirmed aspergillosis and those that were clinically normal presumptively non-Aspergillus infected birds per submitting practitioners' responses to a questionnaire. It was observed that infected birds demonstrated a 2.6-fold increase in galactomannan over birds without evidence of aspergillosis. With the use of a galactomannan index of 0.5 as a cutoff, the sensitivity and specificity of the test were found to be 67% and 73%, respectively. In addition, plasma samples were analyzed for abnormalities in protein electrophoretic patterns. Infected birds had a higher incidence of increased beta and/or gamma globulin concentrations. Test sensitivity and specificity were 73% and 70%, respectively. If the 2 tests were used as a panel, then the sensitivity was 89% and specificity was 48%. These data indicate that both galactomannan and protein electrophoresis may be valuable tools in the diagnosis of avian aspergillosis
Clinical characteristics and outcomes of South-East Asian patients with Takotsubo (stress-induced) cardiomyopathy
Background: There is limited data on the natural history of Takotsubo (stress-induced) cardiomyopathy in South-East Asian patients. We aim to evaluate the clinical characteristics, predisposing factors and outcomes of patients diagnosed with Takotsubo cardiomyopathy in our region. Methods: From January 2010 to March 2017, 98 patients were diagnosed with Takotsubo cardiomyopathy in our institution. Data were collected retrospectively on baseline clinical characteristics, presenting symptoms, precipitating factors, clinical investigations and in-hospital clinical outcomes. Results: 82% of the patients were female. An antecedent physical stressor was more common than emotional trigger with 35% of patients having no identifiable stressor. The most common presenting symptoms were chest pain (53.1%), dyspnea (45%) and diaphoresis (18.5%).The apical variant (89%) was the most common form of Takotsubo cardiomyopathy followed by the mid-ventricular type (5.1%). The mean left ventricular ejection fraction was 35 ± 11%.In-hospital mortality due to cardiovascular causes was 4.1%. 38% of patients developed in-hospital complications. By multi-variable analysis, lower left ventricular function was an independent predictor of in-hospital complication. Conclusion: South-East Asian patients with Takotsubo cardiomyopathy are characterised by female predominance, higher incidence of physical triggers and low cardiovascular mortality. Lower left ventricular function was an independent predictor of adverse outcomes. Keywords: Cardiomyopathy, Complications, Outcome, Stress-induced, Risk factor, South-East Asi
Escarabajo Japonés
El escarabajo Japonés es una plaga invasora que puede ser muy destructiva para plantas ornamentales, árboles, arbustos, césped, y algunas frutas y hortalizas. El EJ probablemente se introdujo desde Japón al este de los EE. UU. en 1916 durante envíos de plantas ornamentales. Ahora está establecido en la mayoría de los estados del este y algunos del medio oeste
