The Impact of Hanseniaspora vineae Fermentation and Ageing on Lees on the Terpenic Aromatic Profile of White Wines of the Albillo Variety

Hanseniaspora vineae is a non-Saccharomyces yeast that has a powerful impact on the sensory profile of wines. Its effect on the aromatic profile of non-aromatic grape varieties, such as Albillo Mayor (Vitis vinifera, L), during vinification is a useful biotechnology to improve sensory complexity. Fermentation in steel barrels using Hanseniaspora vineae and sequential inoculation with Saccharomyces cerevisiae have been used to study the formation of terpenes and cell lysis in the production of Albillo white wines. The GC-MS analysis profile shows a significant effect of H. vineae fermentation on the contents of terpenes (≈×3), mainly in linalool (>×3), β-citronellol (>×4), geraniol (>×2) and α-terpineol (≈×2). The contents of several polyoxygenated terpenes and some volatile phenols with a spicy aroma were increased during fermentation. In summary, Hanseniaspora vineae releases a large number of cell wall polysaccharides during fermentation that affect wine palatability and structure. Hanseniaspora vineae is a powerful bio-tool to enhance the fruitiness, floral notes and freshness in non-aromatic white varieties.
Recent Advances in Bunyavirus Glycoprotein Research: Precursor Processing, Receptor Binding and Structure

The Bunyavirales order accommodates related viruses (bunyaviruses) with segmented, linear, single-stranded, negative- or ambi-sense RNA genomes. Their glycoproteins form capsomeric projections or spikes on the virion surface and play a crucial role in virus entry, assembly, morphogenesis. Bunyavirus glycoproteins are encoded by a single RNA segment as a polyprotein precursor that is co- and post-translationally cleaved by host cell enzymes to yield two mature glycoproteins, Gn and Gc (or GP1 and GP2 in arenaviruses). These glycoproteins undergo extensive N-linked glycosylation and despite their cleavage, remain associated to the virion to form an integral transmembrane glycoprotein complex. This review summarizes recent advances in our understanding of the molecular biology of bunyavirus glycoproteins, including their processing, structure, and known interactions with host factors that facilitate cell entry.
Endocrine Disruptor Potential of Short- and Long-Chain Perfluoroalkyl Substances (PFASs)—A Synthesis of Current Knowledge with Proposal of Molecular Mechanism

Endocrine disruptors are a group of chemical compounds that, even in low concentrations, cause a hormonal imbalance in the body, contributing to the development of various harmful health disorders. Many industry compounds, due to their important commercial value and numerous applications, are produced on a global scale, while the mechanism of their endocrine action has not been fully understood. In recent years, per- and polyfluoroalkyl substances (PFASs) have gained the interest of major international health organizations, and thus more and more studies have been aimed to explain the toxicity of these compounds. PFASs were firstly synthesized in the 1950s and broadly used in the industry in the production of firefighting agents, cosmetics and herbicides. The numerous industrial applications of PFASs, combined with the exceptionally long half-life of these substances in the human body and extreme environmental persistence, result in a common and chronic exposure of the general population to their action. Available data have suggested that human exposure to PFASs can occur during different stages of development and may cause short- or/and long-term health effects. This paper synthetizes the current literature reports on the presence, bioaccumulation and, particularly, endocrine toxicity of selected long- and short-chain PFASs, with a special emphasis on the mechanisms underlying their endocrine actions.
IQGAP1 Is a Scaffold of the Core Proteins of the Hippo Pathway and Negatively Regulates the Pro-Apoptotic Signal Mediated by This Pathway

The Hippo pathway regulates a complex signalling network which mediates several biological functions including cell proliferation, organ size and apoptosis. Several scaffold proteins regulate the crosstalk of the members of the pathway with other signalling pathways and play an important role in the diverse output controlled by this pathway. In this study we have identified the scaffold protein IQGAP1 as a novel interactor of the core kinases of the Hippo pathway, MST2 and LATS1. Our results indicate that IQGAP1 scaffolds MST2 and LATS1 supresses their kinase activity and YAP1-dependent transcription. Additionally, we show that IQGAP1 is a negative regulator of the non-canonical pro-apoptotic pathway and may enable the crosstalk between this pathway and the ERK and AKT signalling modules. Our data also show that bile acids regulate the IQGAP1-MST2-LATS1 signalling module in hepatocellular carcinoma cells, which could be necessary for the inhibition of MST2-dependent apoptosis and hepatocyte transformation.
Utilisation of Chick Embryo Chorioallantoic Membrane as a Model Platform for Imaging-Navigated Biomedical Research

The fertilised chick egg and particularly its chorioallantoic membrane (CAM) have drawn continuing interest in biomedicine and bioengineering fields, especially for research on vascular study, cancer, drug screening and development, cell factors, stem cells, etc. This literature review systemically introduces the CAM’s structural evolution, functions, vascular features and the circulation system, and cell regulatory factors. It also presents the major and updated applications of the CAM in assays for pharmacokinetics and biodistribution, drug efficacy and toxicology testing/screening in preclinical pharmacological research. The time course of CAM applications for different assays and their advantages and limitations are summarised. Among these applications, two aspects are emphasised: (1) potential utility of the CAM for preclinical studies on vascular-disrupting agents (VDAs), promising for anti-cancer vascular-targeted therapy, and (2) modern imaging technologies, including modalities and their applications for real-time visualisation, monitoring and evaluation of the changes in CAM vasculature as well as the interactions occurring after introducing the tested medical, pharmaceutical and biological agents into the system. The aim of this article is to help those working in the biomedical field to familiarise themselves with the chick embryo CAM as an alternative platform and to utilise it to design and optimise experimental settings for their specific research topics.
Serving Children and Adolescents in Need during the COVID-19 Pandemic: Evaluation of Service-Learning Subjects with and without Face-to-Face Interaction

The coronavirus disease (COVID-19) outbreak has posed a great challenge to teaching and learning activities in higher education, particularly for service-learning subjects that involve intensive human interaction. Although service-learning may be transformed to a virtual mode in response to the pandemic, little is known about the impact of this new mode on student learning and well-being. This paper reports a university credit-bearing service-learning subject that involves services toward needy children and adolescents in a non-face-to-face mode under COVID-19 pandemic. We examined the effectiveness of this subject by comparing it with the same subject delivered via a face-to-face mode. Objective outcome evaluation via a pretest-posttest comparison (N = 216) showed that the students who took service-learning subjects with and without face-to-face interaction showed similar positive changes in positive youth development competences, service leadership qualities, and life satisfaction. Subjective outcome evaluation (N = 345) also showed that most students were satisfied with the subject, instructors and benefits regardless of the service mode. The findings highlight the important role of non-face-to-face service learning in promoting college students’ positive growth and well-being.
Validation of a Rapid Multiresidue Method for the Determination of Pesticide Residues in Vine Leaves. Comparison of the Results According to the Different Conservation Methods

The QuEChERS method was applied to the determination of pesticide residues in vine (Vitis vinifera) leaves by LC-MSMS. The method was validated in-house for 33 pesticides representing 17 different chemical groups, that are most commonly used in grape production. Recoveries for the pesticides tested ranged from 75 to 104%, and repeatability and reproducibility relative standard deviations (RSDr% and RSDRw%) were less than 20%. The method was applied to the analysis of pesticide residues in 17 market brands of vine leaves processed according to three different preservation methods and sampled from the Lebanese market. Dried vine leaves were more contaminated with pesticide residues than those preserved in brine or stuffed vine leaves. The systemic fungicides were the most frequently detected among all the phytosanitary compounds usually applied to grape production. Brine-preserved and stuffed vine leaves contained lower concentrations of the residues but still contained a cocktail of different pesticides.
Lu–Hf and Sm–Nd isotope systems in zircon

As a significant carrier of uranium, thorium and the rare earth elements (REEs) at ppm level, and hafnium at the percent level, zircon hosts a remarkable number of long-lived radioactive isotopes and their stable decay products. These include 238U, 235U and 232Th which decay via intermediate steps to 206Pb, 207Pb and 208Pb, respectively, 176Lu which decays to 176Hf, 147Sm which decays to 143Nd, and 138La which undergoes branched decay to 138Ce and 138Ba. This combination makes zircon one of the most versatile minerals available to the geochronologist. Whilst the majority of rock-dating studies involving zircon have utilized the U–Pb and Th–Pb decay schemes, as discussed in previous chapters, an increasing number of investigations are targeting the complementary age information available in the lesser known decay schemes. This chapter reviews the history of application of the Lu–Hf and Sm–Nd isotope systems in zircon and, in its conclusions, speculates on potential future use of the La–Ce system. 176Lu is an unstable radionuclide that undergoes spontaneous β− decay to stable 176Hf, with a half-life of approximately 35 billion years. Variations in the abundance of 176Hf are conventionally expressed with respect to 177Hf whose natural abundance is constant. Thus, the basic age equation for the Lu–Hf dating method, as applied to any closed system, is as follows: \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \[(^{176}Hf/^{177}Hf)\_{t}\ =\ (^{176}Hf/^{177}Hf)\_{initial}\ +\ (^{176}Lu/^{177}Hf)_{t}\ {\cdot}\ (e^{{\lambda}t}\ {-}\ 1)\] \end{document} where t is the elapsed time, and λ is the 176Lu β− decay constant. The exact value of the decay constant λ is currently under review. Most geological studies have either used the value 1.94 × 10−11 y−1, originally calculated from the slope of a Lu–Hf isochron for the 4.56 Ga eucrite achondrite meteorites (Patchett and Tatsumoto 1980a, Tatsumoto et al. 1981), or …
Wastewater treatment works change the intestinal microbiomes of insectivorous bats

Mammals, born with a near-sterile intestinal tract, are inoculated with their mothers’ microbiome during birth. Thereafter, extrinsic and intrinsic factors shape their intestinal microbe assemblage. Wastewater treatment works (WWTW), sites synonymous with pollutants and pathogens, receive influent from domestic, agricultural and industrial sources. The high nutrient content of wastewater supports abundant populations of chironomid midges (Diptera), which transfer these toxicants and potential pathogens to their predators, such as the banana bat Neoromicia nana (Vespertilionidae), thereby influencing their intestinal microbial assemblages. We used next generation sequencing and 16S rRNA gene profiling to identify and compare intestinal bacteria of N. nana at two reference sites and two WWTW sites. We describe the shared intestinal microbiome of the insectivorous bat, N. nana, consisting of seven phyla and eleven classes. Further, multivariate analyses revealed that location was the most significant driver (sex, body size and condition were not significant) of intestinal microbiome diversity. Bats at WWTW sites exhibited greater intestinal microbiota diversity than those at reference sites, likely due to wastewater exposure, stress and/or altered diet. Changes in their intestinal microbiota assemblages may allow these bats to cope with concomitant stressors.
Provider Attitudes and Self-Efficacy When Delivering a Child Sexual Abuse Prevention Module: An Exploratory Study

Background As constant figures in children’s lives, parents are key in protecting children from sexual abuse. One barrier to reaching parents is that the topic can be difficult to broach and is sensitive in nature. Such barriers can interfere with implementation and fidelity of evidence-based prevention strategies that are focused on reducing rates of childhood sexual abuse (CSA). Aims In this exploratory study, we examine provider attitudes about delivering CSA-specific content in an evidence-based prevention module and their self-efficacy. Method Thirty-three providers participated in three surveys: prior to a skills-oriented training on how to deliver the CSA prevention module (pretraining), immediately posttraining, and 6 months posttraining. Changes in self-reported willingness to deliver content, beliefs about parents’ role in CSA prevention, and confidence about their ability to deliver content were assessed over time. Open-ended questions were coded thematically to reinforce quantitative findings. Results Prior to training, providers were worried that parents would respond negatively to CSA content and were concerned about their comfort level discussing victimization and sexual development. Findings suggest that skill-oriented training and provision scripts effectively supported providers and improved confidence in delivering CSA prevention content. Discussion Provider self-efficacy is an important element of implementation fidelity. This exploratory study demonstrated that, though providers may approach CSA content with wariness and trepidation, adequate skills-oriented training can reduce negative attitudes and increase perceived efficacy in the actual delivery of CSA content that persists through implementation. Conclusion Skills-based training can significantly enhance fidelity in the delivery of difficult content included in parent-focused preventative interventions.
Spectroscopic photoacoustic imaging of cervical tissue composition in excised human samples

Objective Cervical remodeling is an important component in determining the pathway of parturition; therefore, assessing changes in cervical tissue composition may provide information about the cervix’s status beyond the measurement of cervical length. Photoacoustic imaging is a non-invasive ultrasound-based technology that captures acoustic signals emitted by tissue components in response to laser pulses. This optical information allows for the determination of the collagen-to-water ratio (CWR). The purpose of this study was to compare the CWR evaluated by using spectroscopic photoacoustic (sPA) imaging in cervical samples obtained from pregnant and non-pregnant women. Methods This cross-sectional study comprised cervical biopsies obtained at the time of hysterectomy (n = 8) and at the scheduled cesarean delivery in pregnant women at term who were not in labor (n = 8). The cervical CWR was analyzed using a fiber-optic light-delivery system integrated to an ultrasound probe. The photoacoustic signals were acquired within the range of wavelengths that cover the peak absorption of collagen and water. Differences in the CWR between cervical samples from pregnant and non-pregnant women were analyzed. Hematoxylin and eosin and Sirius Red stains were used to compare the collagen content of cervical samples in these two groups. Results Eight cervix samples were obtained after hysterectomy, four from women ≤41 years of age and four from women ≥43 years of age; all cervical samples (n = 8) from pregnant women were obtained after 37 weeks of gestation at the time of cesarean section. The average CWR in cervical tissue samples from pregnant women was 18.7% (SD 7.5%), while in samples from non-pregnant women, it was 55.0% (SD 20.3%). There was a significantly higher CWR in the non-pregnant group compared to the pregnant group with a p-value <0.001. A subgroup analysis that compared the CWR in cervical samples from pregnant women and non-pregnant women ≤41 years of age (mean 46.3%, SD 23.1%) also showed a significantly higher CWR (p <0.01). Lower collagen content in the pregnancy group was confirmed by histological analysis, which revealed the loss of tissue composition, increased water content, and collagen degradation. Conclusion The proposed bimodal ultrasound and sPA imaging system can provide information on the biochemical composition of cervical tissue in pregnant and non-pregnant women. Photoacoustic imaging showed a higher collagen content in cervical samples from non-pregnant women as compared to those from pregnant women, which matched with the histological analysis. This novel imaging method envisions a new potential for a sensitive diagnostic tool in the evaluation of cervical tissue composition.
A multicenter, community-based, mixed methods assessment of the acceptability of a triple drug regimen for elimination of lymphatic filariasis

Background Many countries will not reach elimination targets for lymphatic filariasis in 2020 using the two-drug treatment regimen (diethylcarbamazine citrate [DEC] and albendazole [DA]). A cluster-randomized, community-based safety study performed in Fiji, Haiti, India, Indonesia and Papua New Guinea tested the safety and efficacy of a new regimen of ivermectin, DEC and albendazole (IDA). Methodology/Principal findings To assess acceptability of IDA and DA, a mixed methods study was embedded within this community-based safety study. The study objective was to assess the acceptability of IDA versus DA. Community surveys were performed in each country with randomly selected participants (>14 years) from the safety study participant list in both DA and IDA arms. In depth interviews (IDI) and focus group discussions (FGD) assessed acceptability-related themes. In 1919 individuals, distribution of sex, microfilariae (Mf) presence and circulating filarial antigenemia (CFA), adverse events (AE) and age were similar across arms. A composite acceptability score summed the values from nine indicators (range 9–36). The median (22.5) score indicated threshold of acceptability. There was no difference in scores for IDA and DA regimens. Mean acceptability scores across both treatment arms were: Fiji 33.7 (95% CI: 33.1–34.3); Papua New Guinea 32.9 (95% CI: 31.9–33.8); Indonesia 30.6 (95% CI: 29.8–31.3); Haiti 28.6 (95% CI: 27.8–29.4); India 26.8 (95% CI: 25.6–28) (P<0.001). AE, Mf or CFA were not associated with acceptability. Qualitative research (27 FGD; 42 IDI) highlighted professionalism and appreciation for AE support. No major concerns were detected about number of tablets. Increased uptake of LF treatment by individuals who had never complied with MDA was observed. Conclusions/Significance IDA and DA regimens for LF elimination were highly and equally acceptable in individuals participating in the community-based safety study in Fiji, Haiti, India, Indonesia, and Papua New Guinea. Country variation in acceptability was significant. Acceptability of the professionalism of the treatment delivery was highlighted.
Enhanced tunable second harmonic generation from twistable interfaces and vertical superlattices in boron nitride homostructures

Nonlinear optical response from a van der Waals interface is modulated and enhanced in twistable boron nitride homostructures. Broken symmetries induce strong even-order nonlinear optical responses in materials and at interfaces. Unlike conventional covalently bonded nonlinear crystals, van der Waals (vdW) heterostructures feature layers that can be stacked at arbitrary angles, giving complete control over the presence or lack of inversion symmetry at a crystal interface. Here, we report highly tunable second harmonic generation (SHG) from nanomechanically rotatable stacks of bulk hexagonal boron nitride (BN) crystals and introduce the term twistoptics to describe studies of optical properties in twistable vdW systems. By suppressing residual bulk effects, we observe SHG intensity modulated by a factor of more than 50, and polarization patterns determined by moiré interface symmetry. Last, we demonstrate greatly enhanced conversion efficiency in vdW vertical superlattice structures with multiple symmetry-broken interfaces. Our study paves the way for compact twistoptics architectures aimed at efficient tunable frequency conversion and demonstrates SHG as a robust probe of buried vdW interfaces.
Development of a universal chain‐growth polymerization protocol of conjugated polymers: Toward a variety of all‐conjugated block‐copolymers

This manuscript reports a universal chain-growth polymerization protocol for conjugated polymers. Herein, the Pd-based catalyst moiety dissociates from the growing active center into the solution and therefore, the controlled chain-growth character is not relying on any specific, system-related complexation, as is the case in polymerization methods reported before. This makes the protocol applicable on a broad range of monomers and, furthermore, also allows an easy one-pot synthesis of block-copolymers by successive monomer addition. A chain-growth
Quality of Life and Satisfaction in Transgender Men After Phalloplasty in a Retrospective Study

Background Partly as a result of the increasing attention directed toward transgender individuals and despite much research work on the topic of quality of life (QOL) of transgender, there is still a lack of studies using standardized questionnaires in their evaluation. Aims We designed a survey to evaluate the influence of surgery after phalloplasty (osteofasciocutaneous fibula free flap or osteofasciocutaneous radial free forearm flap) on QOL, emotional stability, self-esteem, and psyche of postoperated transgender men. Methods The present study included 32 transgender men who had undergone gender-affirming surgery (GAS) exclusively in our department between 2000 and 2012. Apart from our self-developed, indication-specific questionnaire with questions on socioeconomic and demographic data as well as postoperative satisfaction, the testing instrument included 4 frequently used, standardized testing instruments, which we compared with normative data. These included (a) a self-assessment test Fragebogen zur Lebenszufriedenheit with questions on QOL consisting of 3 modules (general satisfaction, satisfaction with health, and satisfaction with body image/outer appearance), (b) the Freiburg Personality Inventory, (c) the Rosenberg Self-Esteem Questionnaire, and (d) the Patient Health Questionnaire 4. Findings Our self-developed, indication-specific questionnaire showed that 88% of our patients were very satisfied with the aesthetic result, 75% have had sex after surgery, and 72% were very satisfied with sexual function after GAS. Eighty-one percent had a strong improvement of QOL, and 91% would undergo the same treatment again. Eighty-four percent would recommend GAS to others. All patients lived as men fulltime. Discussion Our study reveals that GAS plays an important part in the interdisciplinary treatment of transgender individuals as it improves the QOL in transgender men in most aspects of everyday life and has a positive influence on the patients' psyche and self-esteem in a retrospective study.
