Red list and checklist of the true bugs (Heteroptera) of Berlin

Es wird eine Checkliste und Rote Liste der Wanzen (Insecta: Heteroptera) Berlins vorgelegt. Die Liste umfasst 502 Wanzenarten, die gegenwärtig in Berlin vorkommen oder die seit Mitte des 19. Jahrhunderts wenigstens einmal hier gefunden wurden. 88 Arten (18 %) werden als (regional) verschollen oder ausgestorben betrachtet und 271 Arten (54 %) als nicht bedroht. Sieben Arten sind Neobiota und 11 sind seit 2005 das erste Mal in Berlin nachgewiesen worden. Die wenigen publizierten Arbeiten der letzten Jahre und das Fehlen systematischer Untersuchungen erschweren die Einschätzung der Häufigkeit vieler Arten und ihre Klassifizierung hinsichtlich des Rote-Liste-Status. Besonders bedroht sind Arten von Feuchtgebieten, von fließenden und stehenden Gewässern, Uferbereichen, sowie Arten des Offenlandes. Die Ursachen liegen wie seit Jahren in der zunehmenden Bebau-ung, Zerstörung, Degradierung und Isolation der Standorte und in der Eutrophierung der Lebensräume.A list of 502 Heteroptera species that are currently known from Berlin or at least found once since the mid-19th century is given. 88 species (18 %) are considered (regionally) extinct and 271 species (54 %) of least concern. Seven species are non-indigenous and 11 species are recorded for the first time in Berlin since 2005. The few publications on Heteroptera in the last years and the lack of systematic studies on this group make it difficult to evaluate the frequency of the species and the classification of the threat. Species are particularly endangered in wetlands, extensive dry or wet grasslands, open lands and also in running and still waters. The drivers are urban sprawl, habitat loss, degradation and isolation as well as eutrophication

Serotonin transporter polymorphisms and panic disorder

Panic disorder (PD) is the most common anxiety disorder. Although PD seems to occur unprovoked and the underlying etiology is not well understood, studies have consistently shown that genetic factors explain approximately 48% of the variance. Moreover, family and twin studies support the view that the majority of PD cases have a complex genetic basis. Promising findings have most recently implicated the polymorphisms at the 3' end of the serotonin transporter gene SLC6A4 as PD risk variants. If independent studies can replicate the observed association with the SLC6A4 variants and their functional effects on gene expression, this would have a great impact on our understanding of the disease pathophysiology and would provide opportunities to investigate genotype-phenotype correlations

Material tipo de Cicadellinae (Hemiptera: Cicadellidae) en el Museum für Naturkunde, Humboldt-Universität zu Berlin, Alemania

In this paper, 65 type species of Cicadellinae (Hemiptera: Cicadellidae) are reported from the collections of the Museum für Naturkunde, Universität Humboldt, Berlin, Germany, described by Signoret, Breddin, Schmidt, Jacobi, Schröder, Burmeister and Emmrich. The species of Melichar have not been included because Wilson & Takiya (2007) reported them as present in the Hungarian Natural History Museum.En este artículo, se reportan 65 especies tipo de Cicadellinae (Hemiptera: Cicadellidae) de las colecciones del Museum für Naturkunde, Universidad Humboldt, Alemania, descritas por Signoret, Breddin, Schmidt, Jacobi, Schröder, Burmeister y Emmrich.

A manual and an automatic TERS based virus discrimination

Rapid techniques for virus identification are more relevant today than ever. Conventional virus detection and identification strategies generally rest upon various microbiological methods and genomic approaches, which are not suited for the analysis of single virus particles. In contrast, the highly sensitive spectroscopic technique tip-enhanced Raman spectroscopy (TERS) allows the characterisation of biological nano-structures like virions on a single-particle level. In this study, the feasibility of TERS in combination with chemometrics to discriminate two pathogenic viruses, Varicella-zoster virus (VZV) and Porcine teschovirus (PTV), was investigated. In a first step, chemometric methods transformed the spectral data in such a way that a rapid visual discrimination of the two examined viruses was enabled. In a further step, these methods were utilised to perform an automatic quality rating of the measured spectra. Spectra that passed this test were eventually used to calculate a classification model, through which a successful discrimination of the two viral species based on TERS spectra of single virus particles was also realised with a classification accuracy of 91%

Laser Spectroscopic Technique for Direct Identification of a Single Virus I: FASTER CARS

From the famous 1918 H1N1 influenza to the present COVID-19 pandemic, the need for improved virial detection techniques is all too apparent. The aim of the present paper is to show that identification of individual virus particles in clinical sample materials quickly and reliably is near at hand. First of all, our team has developed techniques for identification of virions based on a modular atomic force microscopy (AFM). Furthermore, Femtosecond Adaptive Spectroscopic Techniques with Enhanced Resolution via Coherent Anti-Stokes Raman Scattering (FASTER CARS) [1] using tip-enhanced techniques markedly improves the sensitivity.Comment: 16 pages, 3 figure
