Reduction in Population After a Year-Long Application of Targeted Sterile Insect Releases in the West Valley Region of Southern California.

is of great public health concern because of its vectorial capacity to transmit various arboviruses such as Zika, yellow fever, dengue, and chikungunya. In California, its expanding geographic distribution has been unrestrained. This urgently calls for innovative tools such as the use of sterile insect technique (SIT) to strengthen invasive control.

Capsaicin attenuates the effect of inflammatory cytokines in a HaCaT cell model for basal keratinocytes.

Introduction: The resolution of the skin's inflammatory response is only possible if its barrier function is restored. TRPV1 channel activation plays an important role during inflammation but the effect of this activation on the skin barrier under inflammatory conditions has not been clarified. We hypothesize that it could potentially aid the keratinocyte barrier by reducing inflammatory cytokine release and promoting tight junction development.

Optimizing and synchronizing Aedes aegypti colony for Sterile Insect Technique application: Egg hatching, larval development, and adult emergence rate.

Mosquito Sterile Insect Technique (SIT) programs can be developed in smaller agencies through synchronization of the colony development to take advantage of the natural male early emergence. This paper examined key aspects of Ae. aegypti colony synchronization work, including egg hatching, larval development, and adult emergence to produce sufficient numbers of adult male mosquitoes within a specific timeframe for irradiation and release.

Antimicrobial Resistance Surveillance: Data Harmonisation and Data Selection within Secondary Data Use.

Resistance to last-resort antibiotics is a global threat to public health. Therefore, surveillance and monitoring systems for antimicrobial resistance should be established on a national and international scale. For the development of a One Health surveillance system, we collected exemplary data on carbapenem and colistin-resistant bacterial isolates from human, animal, food, and environmental sources.

Dissemination of extensively drug-resistant NDM-producing in Europe linked to patients transferred from Ukraine, March 2022 to March 2023.

BackgroundThe war in Ukraine led to migration of Ukrainian people. Early 2022, several European national surveillance systems detected multidrug-resistant (MDR) bacteria related to Ukrainian patients.AimTo investigate the genomic epidemiology of New Delhi metallo-β-lactamase (NDM)-producing from Ukrainian patients among European countries.

Prolonged carriage of OXA-244-carbapenemase-producing Escherichia coli complicates epidemiological investigations.

The rapid increase of OXA-244-producing Escherichia coli, predominantly driven by genetically clustered isolates of sequence type (ST)38, has been observed in at least nine European countries, including Germany. However, the reasons for the spread of OXA-244-producing E. coli remain unclear.

Rapid cross-border emergence of NDM-5-producing in the European Union/European Economic Area, 2012 to June 2022.

Whole genome sequencing data of 874 isolates carrying from 13 European Union/European Economic Area countries between 2012 and June 2022 showed the predominance of sequence types ST167, ST405, ST410, ST361 and ST648, and an increasing frequency of detection. Nearly a third (30.6%) of these isolates were associated with infections and more than half (58.

Molecular surveillance reveals the emergence and dissemination of NDM-5-producing high-risk clones in Germany, 2013 to 2019.

BackgroundCarbapenemase-producing Enterobacterales (CPE) are rapidly increasing worldwide, also in Europe. Although prevalence of CPE in Germany is comparatively low, the National Reference Centre for Multidrug-resistant Gram-negative Bacteria noted annually increasing numbers of NDM-5-producing isolates.AimAs part of our ongoing surveillance programme, we characterised NDM-5-producing isolates received between 2013 and 2019 using whole genome sequencing (WGS).

Overrepresentation of In-Home, Natural Deaths Among Individuals Treated for Mental Illnesses in New York State.

Objective: The authors compared rates of in-home, natural death among individuals receiving treatment for mental illnesses with those in the general population.

Methods: Two data sets were used to determine the prevalence of in-home, natural deaths in the general population and among those receiving treatment for mental illnesses in New York State, outside New York City, for the period 2016-2018.

Results: Overall, 37% of natural deaths among individuals receiving mental health treatment occurred in the home, compared with 26% in the general population.

Increase in NDM-1 and NDM-1/OXA-48-producing in Germany associated with the war in Ukraine, 2022.

In 2022, German surveillance systems observed rapidly increasing numbers of NDM-1- and NDM-1/OXA-48-producing , which may in part reflect recurring pre-pandemic trends. Among these cases, however, a presence in Ukraine before diagnosis was frequently reported. Whole genome sequencing of 200 isolates showed a high prevalence of sequence types ST147, ST307, ST395 and ST23, including clusters corresponding to clonal dissemination and suggesting onward transmission in Germany.

Environmental DNA from archived leaves reveals widespread temporal turnover and biotic homogenization in forest arthropod communities.

A major limitation of current reports on insect declines is the lack of standardized, long-term, and taxonomically broad time series. Here, we demonstrate the utility of environmental DNA from archived leaf material to characterize plant-associated arthropod communities. We base our work on several multi-decadal leaf time series from tree canopies in four land use types, which were sampled as part of a long-term environmental monitoring program across Germany.

Comparison of Indirect and Direct Approaches to Identifying an Unfaithful Partner.

Infidelity has been operationalized inconsistently across studies, and measurement approaches have been employed that are not ideally suited for addressing the stigmatized and subjective nature of infidelity, thereby limiting the conclusions that can be drawn from this body of literature. In 2016, Thompson and O'Sullivan took a step toward addressing these shortcomings by implementing an indirect measurement approach. We extend their findings using a sample of 465 married and divorced individuals via MTurk.

Detection of OXA-181-producing Pseudomonas aeruginosa in Germany.

Objectives: To report the detection of the class D carbapenemase OXA-181 in an MDR clinical Pseudomonas aeruginosa isolate in Germany.

Methods: Carbapenemase detection was performed by using several phenotypic tests such as the modified Hodge test, a combined disc test with boronic acid, EDTA or cloxacillin, a lysate-based inhibition assays and by PCR for common and rare carbapenemase genes. Antibiotic susceptibilities were determined by broth microdilution.

Richness and resilience in the Pacific: DNA metabarcoding enables parallelized evaluation of biogeographic patterns.

Islands make up a large proportion of Earth's biodiversity, yet are also some of the most sensitive systems to environmental perturbation. Biogeographic theory predicts that geologic age, area, and isolation typically drive islands' diversity patterns, and thus potentially impact non-native spread and community homogenization across island systems. One limitation in testing such predictions has been the difficulty of performing comprehensive inventories of island biotas and distinguishing native from introduced taxa.

Individual Sweet Taste Perception Influences Salivary Characteristics After Orosensory Stimulation With Sucrose and Noncaloric Sweeteners.

Emerging evidence points to a major role of salivary flow and viscoelastic properties in taste perception and mouthfeel. It has been proposed that sweet-tasting compounds influence salivary characteristics. However, whether perceived differences in the sensory properties of structurally diverse sweet-tasting compounds contribute to salivary flow and saliva viscoelasticity as part of mouthfeel and overall sweet taste perception remains to be clarified.

Reducing the Bitter Taste of Pharmaceuticals Using Cell-Based Identification of Bitter-Masking Compounds.

The palatability of a pharmaceutical preparation is a significant obstacle in developing a patient-friendly dosage form. Bitter taste is an important factor for patients in (i) selecting a certain drug from generic products available in the market and (ii) adhering to a therapeutic regimen. The various methods developed for identification of bitter tasting and bitter-taste modulating compounds present a number of limitations, ranging from limited sensitivity to lack of close correlations with sensory data.

Characterization of GMB-1, a novel metallo-β-lactamase (MBL) found in three different Enterobacterales species.

Objectives: To identify novel carbapenem resistance mechanisms and their potential to spread among clinical isolates.

Methods: Four clinical isolates of Citrobacter freundii, Serratia marcescens and Raoultella planticola (n = 2) from one hospital in Central Germany were sent to the German National Reference Centre for Multidrug-resistant Gram-negative Bacteria for carbapenemase detection. Phenotypic tests indicated the presence of a metallo-β-lactamase (MBL), but PCR for various MBL genes could not identify any.

Context-aware genomic surveillance reveals hidden transmission of a carbapenemase-producing .

Genomic surveillance can inform effective public health responses to pathogen outbreaks. However, integration of non-local data is rarely done. We investigate two large hospital outbreaks of a carbapenemase-carrying strain in Germany and show the value of contextual data.

Reproductive History in Takotsubo Syndrome, A Register-Based Cohort Study.

Takotsubo syndrome (TS) is a recently recognized serious heart condition that mainly affects women. Despite that 80-90% of the patients are women, few studies have focused on sex-specific characteristics such as female sex hormones and reproductive history. The aim of the study was to compare reproductive history in patients with TS with controls.

Ecological basis and genetic architecture of crypsis polymorphism in the desert clicker grasshopper (Ligurotettix coquilletti).

Color polymorphic species can offer exceptional insight into the ecology and genetics of adaptation. Although the genetic architecture of animal coloration is diverse, many color polymorphisms are associated with large structural variants and maintained by biotic interactions. Grasshoppers are notably polymorphic in both color and karyotype, which makes them excellent models for understanding the ecological drivers and genetic underpinnings of color variation.

TRPA1 Agonist Cinnamaldehyde Decreases Adipogenesis in 3T3-L1 Cells More Potently than the Non-agonist Structural Analog Cinnamyl Isobutyrate.

The cinnamon-derived bioactive aroma compound cinnamaldehyde (CAL) has been identified as a promising antiobesity agent, inhibiting adipogenesis and decreasing lipid accumulation in vitro as well as in animal models. Here, we investigated the antiadipogenic effect of cinnamyl isobutyrate (CIB), another cinnamon-derived aroma compound, in comparison to CAL in 3T3-L1 adipocyte cells. In a concentration of 30 μM, CIB reduced triglyceride (TG) and phospholipid (PL) accumulation in 3T3-L1 pre-adipocytes by 21.

Agonists of Orally Expressed TRP Channels Stimulate Salivary Secretion and Modify the Salivary Proteome.

Natural compounds that can stimulate salivary secretion are of interest in developing treatments for xerostomia, the perception of a dry mouth, that affects between 10 and 30% of the adult and elderly population. Chemesthetic transient receptor potential (TRP) channels are expressed in the surface of the oral mucosa. The TRPV1 agonists capsaicin and piperine have been shown to increase salivary flow when introduced into the oral cavity but the sialogogic properties of other TRP channel agonists have not been investigated.

Rapid spread of OXA-244-producing ST38 in Germany: insights from an integrated molecular surveillance approach; 2017 to January 2020.

Annually, increasing numbers of OXA-244-producing in 13 German federal states prompted us to initiate an outbreak investigation. Whole genome sequencing revealed that among 148 isolates analysed, most belonged to sequence type 38 with 62 isolates forming a genetically distinct cluster. Although no epidemiological link could be identified between cases, ongoing investigations suggest non-healthcare associated transmission.
