Greetings among female chimpanzees in Mahale, Tanzania
Authors: Nakamura Michio 
Published: July 2022

AbstractGreeting behaviors have been reported in several primate species, although their forms and context may vary across species. Chimpanzees (Pan troglodytes) greet each other in various ways when they meet; however, many recent studies of greetings in chimpanzees have mostly focused on pant grunt vocalizations, which are often viewed as equivalent to submissive signals. As most greetings in chimpanzees are directed toward adult males, either from other males or females, relatively few studies have focused on female–female greetings. Thus, the primary aim of this study was to describe the greetings (not limited to pant grunts) between chimpanzee females in the Mahale Mountains National Park based on long‐term observational data. I observed 405 female–female greeting events (10.9 instances per 100 observation hours [obsn. h]) between 1994 and 2018, of which 242 were pant grunts (6.5 instances per 100 obsn. h); 42.3% of greetings were nonaudible, such as tactile or gestural greetings. Most pant grunts were directed toward older females; females under 20 years of age were generally responsible for this trend, as they were the most frequent greeters among females and tended to perform pant grunts toward older females. Nonetheless, among females 20 years of age or older, pant grunts from an older to a younger female were not rare (37%). Compared to previous studies in Mahale, pant grunts between females were an order of magnitude less than those directed toward males. There may also be a large difference in the frequencies of female–female pant grunts across study sites, which may be attributed to differences in female gregariousness.

AbstractDie elektrokatalytische Wasserspaltung gilt als die nachhaltigste und sauberste Technologie zur Produktion von H2. Leider wird die Effizienz durch die träge Kinetik der Sauerstoffentwicklungsreaktion (OER) an der Anode stark eingeschränkt. Im Gegensatz zur OER ist die Elektrooxidation organischer Stoffe (EOO) thermodynamisch und kinetisch günstiger. Daher hat sich die Kopplung der EOO mit der Wasserstoffentwicklungsreaktion (HER) als Alternative herauskristallisiert, weil dabei die katalytische Effizienz für die H2‐Produktion erheblich verbessert werden kann. Gleichzeitig können hochwertige organische Verbindungen an der Anode durch Verbesserung der Elektrooxidation erzeugt werden. In diesem Kurzaufsatz werden die aktuellsten Fortschritte und Meilensteine, die bereits bei der Kopplung der EOO mit der HER erzielt wurden, vorgestellt. Der Fokus liegt auf dem Design des Anodenkatalysators, dem Verständnis des Reaktionsmechanismus und der Konstruktion des Elektrolyseurs. Darüber hinaus werden Herausforderungen und Perspektiven in Bezug auf die künftige Entwicklung dieser innovativen Technologie aufgezeigt.

AbstractWith the development of wearable electronic devices, there has been extensive research interest in portable energy supply systems. In this study, traditional cotton fabrics are finished with a water repellent coating and a single‐sided polyurethane (PU) coating to impart hydrophobicity. The hydrophobic lightweight cotton fabric can float on the surface of the pyrrole polymerization system solution. With increasing polymerization time, the pyrrole continues to polymerize and deposit on the side in contact with the fabric, resulting in a one‐sided conductive fabric. The highest doping level was obtained for the polypyrrole (PPy) coating for polymerization time of 12 h. For PPy coating thickness of 18 μm, the square resistance was as low as 220 Ω/sq. The PPy‐12 fabric electrode showed excellent electrochemical performance and cycling stability. An interdigitated pattern was etched on the surface of the one‐sided conductive fabric (PPy‐12) using a N, N‐dimethylformamide solution. Fabric micro‐supercapacitors were obtained by assembling with a H2SO4/PVA gel electrolyte. The fabric micro‐supercapacitor exhibited good flexibility and electrochemical energy storage properties. For current density of 0.08 mA/cm2 and power density of 19.1 μW/cm2, the energy density of the device was 0.09 μWh/cm2. After 3000 cycles, the micro‐supercapacitor retained approximately 85% of the capacitance. Thus, fabric‐based flexible micro‐supercapacitors have excellent application potential in the field of energy storage.

Published: July 2022

AbstractIn this study, four types of cellulose nanomaterials obtained from wheat straw including cellulose nanocrystals (CNCs), TEMPO oxidized cellulose nanofibers (TCNFs), mechanical‐driven cellulose nanofibers (MCNFs) and lignocellulose nanofibers (LCNFs) were first produced and then separately added to carboxymethyl cellulose (CMC) with different mixing ratio of 1, 3, and 6 wt% to make nanocomposite. Pure CMC film and cellulose microfibers (CFs) reinforced composite were also fabricated. BET test showed that TCNFs and CFs had the highest (124 m2/g) and lowest (3.6 m2/g) specific surface area, respectively. FE‐SEM confirmed that TCNFs and CFs presented the thinnest (8 ± 4 nm) and the thickest (24 ± 7 μm) fibers. The nanocomposite containing TCNFs had a transparency of 56%, while CF‐CMC composite showed the lowest one (18%). After the addition of cellulose nanomaterials the XRD peaks of nanocomposites became narrower and shifted partly to the right side compared to that of pure CMC. The highest and lowest water vapor permeability values obtained for rod‐like CNC reinforced nanocomposite and pure CMC film, respectively. The nanocomposite containing 6 wt% TCNFs showed the highest tensile strength and Young's modulus. Cellulose nanomaterials positively affected on the strain at break of the nanocomposites.

Abstract

Artisanal fisheries are socially and economically important along the Caribbean coast of Colombia. These fisheries remain poorly characterized, making it difficult to estimate their potential impact, especially on non‐targeted catch such as elasmobranchs.
A rapid assessment framework was used to investigate the exploitation, use, and relative abundance of elasmobranchs and predatory teleosts in a region along the Caribbean coast of Colombia. In‐person structured interview surveys (n = 188) were conducted during the autumn of 2016 at eight fishing towns around Cartagena and the islands of the Natural National Park (NNP) Corales del Rosario and San Bernardo. Baited remote underwater video systems (BRUVS) (n = 200) deployed at four reefs were used to assess the relative abundance of elasmobranchs and other predatory teleosts.
Fishers reported capturing eight shark and five ray taxa. Although 99% of fishers indicated that they did not target sharks, 83% reported keeping the catches to sell, eat, or both. Similarly, 81% of fishers did not target rays, but 90% reported retaining catches. Most fishers (84%) perceived a decline of sharks in the coastal waters since they started fishing, compared with 41% reporting batoid declines. BRUVS data support the perceptions of elasmobranch declines. Elasmobranch abundances were very low and no difference was detected between protected and unprotected reefs. Results were similar for teleost taxa, but there were higher abundances inside one marine protected area (MPA) that had high enforcement.
Taken together, the data suggest considerable degradation of not only elasmobranch populations but also predatory fish populations of coral reef habitats in a region of the Colombian Caribbean. Furthermore, artisanal fishers continue to exploit coral reef resources inside MPAs unless there is strong enforcement. Enforcement can be difficult with limited resources, and therefore community‐based conservation methods may be more effective. Engagement with the local fishing community may help to reduce existing tensions and improve compliance.

AbstractThe SARS‐CoV‐2 virus is responsible for the COVID‐19 pandemic the world experience since 2019. The protein responsible for the first steps of cell invasion, the spike protein, has probably received the most attention in light of its central role during infection. Computational approaches are among the tools employed by the scientific community in the enormous effort to study this new affliction. One of these methods, namely molecular dynamics (MD), has been used to characterize the function of the spike protein at the atomic level and unveil its structural features from a dynamic perspective. In this review, we focus on these main findings, including spike protein flexibility, rare S protein conformational changes, cryptic epitopes, the role of glycans, drug repurposing, and the effect of spike protein variants.

AbstractAlthough poly(imide)‐based separators have received great attention as an alternative separator for lithium‐ion batteries, there are serious restrictions because their porous structures enable a great amount of current to leak internally. In this work, we report a one‐step coating process for the structures of poly(imide) (PI)‐based separators that effectively closes their pores. To close the large pores on a PI separator, nanosized aluminum oxide as a coating precursor and the free radical scavenging agent ethylene bis(diphenylphosphine) were co‐incorporated into the PI separator. Screening tests confirmed that ethylene bis(diphenylphosphine) (EPP) can effectively scavenge free radical species via chemical reaction and that incorporating Al2O3–EPP composites closed pores of the PI separators. Regarding electrochemical performance, the cell cycled with a PI separator that incorporated Al2O3–EPP exhibited stable cycling, while the cell cycled with a bare PI separator showed failure. These results indicate that incorporating Al2O3–EPP material effectively increases both safety and electrochemical performance. The Al2O3–EPP composites are incorporated onto the PI separator via dip‐coating process in order to improve electrochemical properties of PI separator. The cell cycled with the Al2O3–EPP incorporated PI separator exhibits stable cycling behavior because Al2O3–EPP composites effectively prevent internal short circuit in the cell.

AbstractBackgroundThere were controversies for the association between computed tomography (CT)‐determined low skeletal muscle mass (SMM) and overall survival (OS) in gastric cancer (GC). In this study, we investigated whether cachexia could be a potential confounding variable for this issue.MethodsWe retrospectively collected the patients of GC in our institution between July 2016 and January 2021. Preoperative SMM was determined by analyzing the skeletal muscle index of L3 with abdominal CT, and the cut‐offs for low SMM were defined as <52.4 (men) and < 38.5 cm2/m2 (women), respectively. Overall survival (OS) was the primary endpoint.ResultsOf the 255 included GC patients, 117 (46%) were classified as having low SMM. Those with low SMM were associated with a higher level of circulating interleukin 6 and C reactive protein but a lower level of albumin than those of normal SMM. The univariate analysis showed that low SMM, tumor‐node‐metastasis (TNM) stage, body mass index (BMI), postoperative chemotherapy, and cachexia were significantly associated with OS, while in the multivariate analysis, only low SMM and TNM stage were significantly associated with OS. Kaplan–Meier survival curves with log‐rank tests indicated that low SMM significantly predicted worse OS of GC. After grouping by cachexia, the low SMM significantly predicted worse OS in patients with cachexia instead of those without cachexia.ConclusionsCT‐determined low SMM predicts worse OS of GC in patients with cachexia instead of those without cachexia, and greater attention should be paid to such patients with synchronous low SMM and cachexia.
Investigating clients' experiences of walk and talk counselling
Authors: Newman Erica , Gabriel Lynne 
Published: July 2022

AbstractBackgroundThe use of “walk and talk” counselling has recently increased due to the COVID‐19 pandemic, concurrent with an increased awareness of the benefits of the outdoors, nature and exercise on mental health. Walk and talk counselling is relatively new and seemingly easy to incorporate for everyday counsellors. However, there is limited previous research on this form of counselling.AimThis study aimed to investigate how the client experiences walk and talk counselling in a natural outdoor environment.MethodTo evaluate the client's lived experience of walk and talk counselling, online semi‐structured interviews with five adult participants in the United Kingdom (UK) were analysed using the interpretative phenomenological analysis (IPA) method.FindingsThe general outlook on walk and talk was positive. There was a feeling of informality, and a relational equalising element, but these aspects did not appear to detract from the professional relationship. There was an appreciation of nature, although there was an element of not noticing it. Timing was more fluid, and there were positive and negative aspects of the outdoor walking.LimitationsA small sample size limits the wider application of these findings.ImplicationsFurther research is required to support further guidelines and training for practitioners. Implications for practice include the consideration of client preferences and a more fluid approach to contracting, a need for increased awareness of physical and psychological safety and a consideration of the relational dynamic when walking outdoors.ConclusionWalk and talk is a viable alternative to indoor counselling. It proved useful in a pandemic and for clients who would not consider indoor counselling.

Published: July 2022

AbstractMelatonin (MEL) has antioxidant properties and participates in osteogenic differentiation. In periodontitis, in which increased oxidative stress and bone resorption are involved, mesenchymal stem cells derived from the gingiva (GMSCs) combined with MEL could be relevant for osteogenic regeneration. In this study, we studied the antioxidant and differentiating effect of MEL on an in vitro system of GMSCs. Primary culture of GMSCs from Wistar rats was developed to evaluate differentiation into osteoblasts with an appropriate medium with or without MEL. Marker genes of mesenchymal stem cells by real time‐polymerase chain reaction, clonogenic capacity, and cell migration after wound assay were used to characterize GMSCs as mesenchymal stem cells. Alkaline phosphatase activity and the alizarin red technique were used to evaluate osteogenic activity and differentiation. MEL increased alkaline phosphatase activity and alizarin red values, promoting osteogenic differentiation. Besides this, MEL protected GMSCs in a model of cellular damage related to oxidative stress, returning viability to baseline. MEL was more effective in promoting and protecting GMSCs by the production of osteogenic cells when oxidative stress is present. This evidence supports the use of MEL as a novel bone‐regenerative therapy in periodontal diseases.

Published: July 2022

AbstractBilateral bidirectional Glenn shunts are associated with the risk of developing pulmonary artery bifurcation stenosis, resulting in variable pulmonary blood flow to either lung. This could negatively impact the subsequent stages of the single ventricle palliation pathway. This report highlights the value of 4D flow sequence from the cardiac magnetic resonance imaging in demonstrating the pulmonary blood flow characteristics following a bilateral bidirectional Glenn procedure. Mapping the blood flow pattern and its quantification to each lung provide objective insights into the possible predisposing factors for the development of pulmonary bifurcation stenosis.

Published: July 2022

AbstractA bimetallic‐catalyzed oxidative esterification reaction has been conducted between non‐activated C(sp3)–H bonds of symmetric ethers and carboxylic acids with the presence of di‐tert‐butyl peroxide as the oxidant through a cross‐dehydrogenative coupling (CDC) reaction. This approach allows the derivatives of cyclic ether substrates to interact with aromatic acids, giving excellent yields for the formation of α‐acyloxy ethers. The bimetallic organic frameworks catalyst (Fe2Ni‐BDC) that had been synthesized by solvothermal method was successfully utilized for the formation of α‐acyloxy ethers based on the CDC reaction of carboxylic acid with diethylene oxide (approx. 84 % product yield). Besides, this material was also used as catalyst for research scope of benzoic acid containing various substituents.

Published: July 2022

AbstractA graphite‐based ion‐imprinted polymer (G‐IIP) was synthesized using the surface‐printing technique. Allylthiourea was used as the functional monomer, nitrate as the template, and ethylene glycol dimethacrylate as a crosslinker. The polymers were characterized, and the adsorption capacity was tested. The binding ability of G‐IIP was nearly twice higher than that of the graphite‐non‐imprinted polymer (G‐NIP). The adsorption of G‐IIP followed the Freundlich isotherm and the pseudo‐second‐order kinetic. G‐IIP showed good removal efficiency of nitrate ions in actual wastewater samples with 85 % recovery. Overall, the fabricated G‐IIP would be a potential adsorbent for wastewater treatment.

AbstractThe dynamic nature of excited‐state intramolecular proton transfer (ESIPT) and its effect on emission spectra is an attractive strategy to create multi‐emissive dyes. Here we describe the behavior of a series of hydrogen‐bonded triphenylpyridines with a set of donor–acceptor combinations that allowed us to perceive the influence of each substitution on the photophysical properties of the dyes. The susceptibility of these ESIPT moieties to pH variations was also studied, elucidating that the level of protonation had a significant effect on the emission color. The assignment of each emission band was made by using DFT and td‐DFT calculations that were in agreement with the experimental results. This study emphasizes the versatility of triphenylpyridines that can be synthesized effortlessly with a logical and independent C‐2, C‐4 and C‐6 substitution in order to have the desired ESIPT modulation and subsequent multi‐emission response.
