AbstractAimA primary goal of community ecology is to understand the mechanisms that drive species' spatial distribution and habitat associations. Species' geographic distribution can be influenced by the distribution of their prey partly because consumers' behaviour is oriented to optimal energy use during foraging. We analysed how differences in dietary preferences influence the spatial distribution and habitat associations of species at the landscape scale. We hypothesized that differences in feeding guilds will lead to divergent habitat association patterns among species.LocationAmazon River drainage basin.TaxonCharaciform fishes in the family Serrasalmidae (piranhas and pacus).MethodsWe used diet data to classify species into feeding guilds (frugivores, herbivores, piscivores, fin and scale feeders and planktivores). We used three proxies of habitat association derived from satellite products: floodplain extent, landscape heterogeneity and flood duration, in three distance buffers. We implemented phylogenetic generalized least squares models to evaluate the relationship between habitat association and feeding guilds.ResultsFrugivores, piscivores and fin and scale feeders presented similar patterns of habitat associations, with frugivores occupying wider areas of floodplain and greater landscape heterogeneity. Herbivores and planktivores were associated with smaller floodplain extents and lower landscape heterogeneity. All feeding guilds were associated with similar levels of flood duration.Main conclusionsDifferences in resource distribution (assessed through feeding guilds) can influence habitat association. Considering the hydrological variability (i.e. floodplain extent) and landscape heterogeneity that characterize floodplains, the patterns of habitat association vary with the spatial scale considered. This work highlights the importance of understanding species habitat associations by fish as well as food resource dynamics and floodplain dependence. This realization is critical for assessing the impact of anthropogenic activities on freshwater ecosystems.

AbstractAlthough it is common for bi‐atrial tachycardia (AT) circuits to include the Bachmann bundle, there are few reports of its role in left AT circuits. A 77‐year‐old man was admitted for recurrent AT with a cycle length of 425 ms. The endocardial and epicardial activation map revealed an AT circuit located in the left atrial anterior wall and transverse pericardial sinus, showing a centrifugal pattern stemming from the left atrial appendage. After radiofrequency ablation, AT was no longer induced. This case suggests that the Bachmann bundle may be part of the left AT circuit.

AbstractBackgroundAmelanotic/hypomelanotic lentigo maligna and lentigo maligna melanoma (AHLM/LMM) may be very difficult to diagnose at an early stage.ObjectivesTo quantify the predictive value of dermoscopic and reflectance confocal microscopy (RCM) features for AHLM/LMM.MethodsDermoscopic and RCM images of histopathologically diagnosed AHLM/LMM, amelanotic/hypomelanotic benign lesions (AHBL), and amelanotic/hypomelanotic basal and squamous cell carcinomas (AHBCC/AHSCC) of the head and neck from consecutive patients were retrospectively collected and blindly evaluated by three observers to assess presence or absence of dermoscopic and RCM criteria.ResultsOverall, 224 lesions in 216 patients including LM/LMM (n = 55, 24.6%), AHBL (n = 107, 47.8%) and AHBCC/AHSCC (n = 62, 27.7%) were analysed. Multivariable analysis showed that milky‐red areas (OR = 5.46; 95% CI: 1.51–19.75), peripheral light brown structureless areas (OR = 19.10; 4.45–81.96), linear irregular vessels (OR = 5.44; 1.45–20.40), and asymmetric pigmented follicles (OR = 14.45; 2.77–75.44) at dermoscopy, and ≥3 atypical cells in five fields (OR = 10.12; 3.00–34.12) and focal follicular localization of atypical cells at dermo‐epidermal junction (DEJ) (OR = 10.48; 1.10–99.81) at RCM were significantly independent diagnostic factors for AHLM/LMM vs. AHBL. In comparison with AHBCC/AHSCC, peripheral light brown structureless area (OR = 7.11; 1.53–32.96), pseudonetwork around hair follicles (OR = 16.69; 2.73–102.07), and annular granular structures (OR = 42.36; 3.51–511.16) at dermoscopy and large dendritic (OR = 6.86; 3.15–38.28) and round pagetoid cells (OR = 26.78; 3.15–227.98) at RCM led to a significantly increased risk of diagnosing AHLM/LMM.ConclusionsAmelanotic/hypomelanotic lentigo maligna and lentigo maligna melanoma may have the same dermoscopic features of AHM on other body sites, such as milky red areas, peripheral light brown structureless areas and linear irregular vessels. These features, asymmetric pigmented follicles and at RCM ≥ 3 atypical cells in five fields and focal follicular extension of atypical cells at DEJ may help in recognizing AHLM/LMM even when LM conventional features (e.g., obliteration of hair follicles under dermoscopy and large pagetoid cells under RCM) are absent or present only in very small areas of the lesion.

Published: October 2022

AbstractPlants often associate with multiple arthropod mutualists. These partners provide important services to their hosts, but multiple interactions can constrain a plant's ability to respond to complex, multivariate selection. Here, we quantified patterns of genetic variance and covariance among rewards for pollination, biotic defence and seed dispersal mutualisms in multiple populations of Turnera ulmifolia to better understand how the genetic architecture of multiple mutualisms might influence their evolution. We phenotyped plants cultivated from 17 Jamaican populations for several mutualism and mating system‐related traits. We then fit genetic variance–covariance (G) matrices for the island metapopulation and the five largest individual populations. At the metapopulation level, we observed significant positive genetic correlations among stigma–anther separation, floral nectar production and extrafloral nectar production. These correlations have the potential to significantly constrain or facilitate the evolution of multiple mutualisms in T. ulmifolia and suggest that pollination, seed dispersal and defence mutualisms do not evolve independently. In particular, we found that positive genetic correlations between floral and extrafloral nectar production may help explain their stable coexistence in the face of physiological trade‐offs and negative interactions between pollinators and ant bodyguards. Locally, we found only small differences in G among our T. ulmifolia populations, suggesting that geographic variation in G may not shape the evolution of multiple mutualisms.

Published: October 2022

AbstractAlthough oogonial proliferation continues in mature females in most teleosts, its dynamics and the transformation of oogonia to early meiotic oocytes during the reproductive cycle have received little attention. In the present study, early oogenesis was examined throughout the reproductive cycle in two Clupeiform fishes, the Mediterranean sardine, Sardina pilchardus, and the European anchovy, Engraulis encrasicolus. Observations using confocal laser scanning microscopy (CLSM) provided extensive information on markers of oogonial proliferation (mitotic divisions, oogonia nests) and meiotic prophase I divisions of oocyte nests (leptotene, zygotene, pachytene, diplotene) in ovaries of different reproductive phases. In sardine, oogonial proliferation persisted throughout the entire reproductive cycle, whereas in anchovy, it was more pronounced prior to (developing ovaries) and after (resting ovaries) the spawning period. Anchovy exhibited a higher rate of meiotic activity in developing ovaries, whereas sardine exhibited a higher rate in resting ovaries. The observed differences between the two species can potentially be attributed to different seasonal patterns of energy allocation to reproduction and the synchronization between feeding and the spawning season.

Published: October 2022

AbstractOne of the promising approaches in food sector is the valorization of food by‐products into nutritional ingredients. This study aimed to improve the quality of toffee by adding mango kernel fat (MKF) as a butter replacer (50%), pectin (1%) using the high‐speed homogenization (HSH). Fatty acid composition, melting point, non‐enzymatic browning index (NEBI), texture profile analysis (TPA) were investigated. Results showed the oxidative stability of MKF recorded exceeding value (400 h) indicating great stability compared to butter (21 h), using HSH technique with the addition of pectin and mango fat to toffee induced high‐quality characteristics. Also, an increase in stability of toffee blends (zeta potential: −80 mV), melting point (34.129°C), TPA of the blends was compatible with full butter TPA with high texture, and high acceptability was observed. Results demonstrate that toffee with MKF and using HSH could improve the quality characteristics of toffee as well as have good nutritional aspects.Novelty impact statementImproving the quality attributes of toffee confectionery by reducing fat in the recipe as substituted using a high‐speed homogenization technique, with mango fat and/or pectin as a fat replacer. They could make toffee lower in fat content, healthier, cheaper, and with the same quality as full‐fat toffee. It will valorize the mango fat from mango by‐products into nutritional ingredients.

AbstractThe uneven maturity and severe internal rot of kiwifruit were rapidly accelerated when transferred to room temperature after long‐term controlled atmosphere storage. In this study, the effects of ethrel combined with different flow microcirculation of antiseptic mediums on the shelf‐life quality of “Qinmei” kiwifruit stored at 20°C were evaluated. Results indicated that the combined aerosolization application of 500 mg/L natamycin, 7.5% w/w H2O2 and 0.5 mg/L atomized ozone could control the decay incidence and respiratory rate of ethrel‐treated kiwifruit. Further studies indicated that ethrel and O3 treatment greatly increased the activities of chitinase, β‐1,3‐glucanase, catalase, and superoxide dismutase and produced higher ascorbic acid levels (151.16 mg·100 g−1/FW) to enhance disease‐resistant of kiwifruit. This treatment could inhibit the activity of polyphenol oxidase and delay the process of membrane lipid peroxidation, contributing to preserving the integrity of cell structures well. Moreover, ethrel + O3 treatment could effectively reduce ethylene production (3.12 μl/kg/h) to delay the ripening and senescence of fruit stored at 20°C. More importantly, this treatment exhibited the lowest contents of decay incidence (9.75%), total bacterial count (4.07 log cfu/g), and yeasts and molds (4.18 log cfu/g), and thus extended the shelf life for up to 16 days. Therefore, a combination of ethrel and ozone is a potentially effective method for the maintenance of the shelf‐life properties of kiwifruit after long‐term cold storage.Novelty impact statementIn this study, the treatment of ethrel‐treated with aerosolized ozone of flow microcirculation of 0.5 mg/L O3 could effectively suppress ripening and senescence, enhance antioxidant capacity and disease resistance, reduce the degree of membrane lipid peroxidation, and considerably preserve the integrity of cell structures, which contributed to preventing the penetration of pathogens, retarding the decay incidence, and delaying the shelf‐life quality deterioration of kiwifruit transferred to room temperature after long‐term controlled atmosphere storage.

Published: October 2022

AbstractThe aroma intensities of rice depend on the variety and the volatile compound content. Many volatile compounds in rice have been identified for their biological activity. In this study, we investigated the biological activity and the volatile compounds content of pigmented rice and non‐pigmented rice extracts. We also investigated the inhibition potential of volatile compounds including methyl vanillate, vanillin, 2‐pentyl furan and guaiacol against acetylcholinesterase through in vitro and in silico studies. The results reveal that the total phenolic and total flavonoid content was closely related to the antioxidant potential of pigmented rice and non‐pigmented rice extracts. The strongest inhibition potential of volatile compounds against acetylcholinesterase was obtained from methyl vanillate followed by 2‐pentyl furan and vanillin. Guaiacol had the lowest inhibition potential. Docking studies also indicated that strong binding affinity was obtained from methyl vanillate followed by 2‐pentyl furan, vanillin and guaiacol, respectively. The highest methyl vanillate and vanillin contents were obtained from Khao Leum Pua. The highest content of 2‐pentyl furan was obtained from Khao Leum Klaeng. Interestingly, the highest inhibition potential against acetylcholinesterase was also investigated from Khao Leum Klaeng and followed by Khao Leum Pua, respectively. The results indicated that the volatile compounds including methyl vanillate, 2‐pentyl furan and vanillin seem to be the key compounds for acetylcholinesterase inhibitory activity in these rice extracts.Practical applicationsMethyl vanillate, 2‐pentyl furan and vanillin are the key compounds for acetylcholinesterase inhibitory activity of rice extracts. Our findings provided candidate compounds for application in the treatment of Alzheimer's disease (AD) and also benefit on human health.

AbstractDuring the storage process of hazelnut fresh fruits, browning is easy to occur, which reduces the storage quality. In this study, the method of 60Coγ irradiation was used to dynamically monitor the effects of fresh hazelnuts on storage quality, physiological indicators, and sterilization effect after being irradiated and refrigerated at 4 ± 0.5°C for 3 months. The results showed that irradiation at a dose of 0.25 to 1.0 kGy could preserve the current quality of the product, delay the browning of hazelnut shells, and reduce the activity of polyphenol oxidase. In addition, 0.5 kGy irradiation inhibited the respiration intensity and the accumulation of malondialdehyde in hazelnut fruits at the later stage of storage. Further research found that the content of microorganisms in hazelnut fruits decreased with the increase in irradiation dose. In addition, 0.5 kGy was the best irradiation dose to slow down the transpiration of hazelnut water and delay the reduction of fat, but the irradiation treatment of less than 1.0 kGy was effective for hazelnuts. Fruit peroxide value had no significant effect. At the same time, through the principal component analysis of hazelnut fruits stored for 90 days, the results also show that the 60Coγ irradiation with a dose of 0.5 kGy has the best storage effect and can effectively prolong the shelf life. The results of this study provide an effective theoretical basis and technical support for the preservation of fresh hazelnut fruits and the inhibition of the browning of hazelnut shells during storage.Novelty impact statementIn this study, 60Coγ irradiation inhibited the polyphenol oxidase activity of polyphenol oxidase to a certain extent, thus delaying the browning of hazelnut shells. The synergistic effect of irradiation and low temperature prolonged the shelf life of hazelnut. The results showed that treatment with 0.5 kGy had the best effect, which was validated by the results of principal component analysis.

Published: October 2022

AbstractAimTo evaluate the success of local methotrexate (MTX) treatment, the side‐effect profile and its fertility effect in patients diagnosed with cesarean scar pregnancy.MaterialsThis retrospective cohort study included 56 cesarean scar pregnancy patients who applied to Erciyes University Faculty of Medicine, Department of Obstetrics and Gynecology between January 2012 and January 2022 and were treated with ultrasound‐guided local MTX. The results of 56 patients with cesarean scar pregnancy who underwent transvaginal ultrasound‐guided single‐dose local MTX treatment were evaluated. First, the contents of the sac were aspirated, and then 50 mg of MTX was injected into the gestational sac.ResultsThe median gestational age at diagnosis was 7 weeks 2 days. The mean beta human chorionic gonadotrophin level was 31 345 ± 37 838 (range: 113–233 835 mIU/mL). Fifty‐four patients were successfully treated with local MTX therapy. The interval between the first MTX injection and the normalization of beta human chorionic gonadotrophin was 55.2 ± 41.0 days. None of our patients required surgical treatment. Beta human chorionic gonadotrophin values did not decrease in one patient and she was treated with systemic MTX. Local MTX therapy could not be applied to one patient for technical reasons. Only one patient needed blood transfusion after local MTX. Thirteen patients become pregnant after treatment (76%). No systemic side effects related to MTX were observed in any of the patients.ConclusionTransvaginal ultrasound‐guided single‐dose local MTX treatment is an effective, safe, and fertility‐preserving treatment method for cesarean scar pregnancy.
Identification of novel genetic and epigenetic regulators of different tissue types of cervical cancer
Authors: Chandra Sanchita , Sarkar Subham , Mandal Paramita 
Published: October 2022

AbstractObjectivesThe study aimed to find differential gene mutations, DNA methylation, and expression profiles among different categories of cervical cancer samples.MethodsThe study was based on freely available gene mutations, promoter methylation, and gene expression status of The Cancer Genome Atlas (TCGA) cervical cancer samples and adjacent normal tissues in the Genomic Data Commons (GDC) portal. The association of CpG island methylation with gene expression was determined through negative correlation analysis.ResultsWe identified that the ErbB signaling pathway and proteoglycans pathway was significantly associated with adenocarcinoma cervical cancers patients. In these pathways, missense mutation especially S310F in theERBB2gene as well as G12D and A146T in theKRASgene were significantly associated with adenocarcinoma cases. Furthermore, a comparison of SCC cases with adjacent control tissues revealed differential hypermethylation of two CpG positions of theKAAG1gene and differential downregulation ofNPY1RandNPY5Rgenes in cervical squamous cell carcinoma compared to cervical adenocarcinoma cases and adjacent normal tissues. Specifically, the hypermethylation of the promoter region of theKAAG1gene might be responsible for the carcinogenesis of cervical squamous cells exclusively and methylation marks can be reversible by the widely used drug, azacytidine. In contrast, adenocarcinoma cervical cancer cases may be treated with floxuridine which is successfully utilized for other tissue‐specific adenocarcinoma cases.ConclusionsThese results provide valuable insight into the differential molecular markers among the categories of cervical cancer, which helps our ability to classify these cancers and for targeted therapy.
Empowering leadership, promotion focus, and creativity: Gender matters
Authors: Lang Yi , Huang Mingpeng , Tian Guangdi 
Published: October 2022

AbstractPrevious research on the relationship between empowering leadership and employee creativity has found mixed results, calling for more research to explore alternative mechanism and boundary conditions in this relationship. In this research, drawing on regulatory focus theory and social role theory, we propose that empowering leadership has a positive relationship with employee creativity through employee promotion focus and that this relationship is stronger for male (vs. female) leaders and for female (vs. male) employees. We conducted a multi‐source survey study and a vignette experiment to test our theoretical model. Results across these two studies supported our hypotheses. Our findings offer implications for research and practice regarding empowering leadership and creativity.
