AbstractA glass foam (GF) of high specific compressive strength (12.17±1.91 MPa g−1 cm−3) and low thermal conductivity (.121±.001 Wm−1 K−1) was produced from waste glass of photovoltaic module, eggshells, and bentonite clay. The influences of the amount of clay and heat‐treatment temperature on the GFs final properties were assessed. X‐ray diffraction results and the data of microscopic analyses demonstrated that addition of clay affected the structure and porosity of the GFs, and consequently their mechanical properties. On the basis of the mechanical property (density), the GF that composed of 80% waste glass, 10% clay, and 10% eggshell at the sintering temperature of 900°C was the best. The GFs reported in this study could serve as promising insulators in situations where high load support is required.

SummarySenescence accompanying browning is the main factor that reduces the sensory and nutritional quality of cherries during storage. In the present study, we analysed the effects of sodium nitroprusside (SNP) treatment with 0, 200, 400, and 600 μm on delaying the senescence and browning of cherries preserved at 4 °C for 30 days. Results suggested that 400 μm SNP treatment significantly enhanced the antioxidant capacity and maintained better fruit quality. Specifically, SNP treatment inhibited the activity of polyphenol oxidase, delayed the browning of cherry flesh and reduced soluble quinone content. Meanwhile, the peroxidase (POD), catalase and phenylalanine ammonia‐lyase (PAL) activities were enhanced by SNP treatments, while reactive oxygen species accumulation and membrane lipid peroxidation were alleviated. In addition, SNP treatment increased the accumulation of phenols, flavonoids and anthocyanins, which also enhanced the 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) scavenging capacity in cherries. Therefore, our results support SNP treatment to be a potential approach to delay flesh browning and maintain the sensory and nutritional qualities of cherries.

Authors: Lamouri Rachida , Kim Ki Hyeon 
Published: June 2023

AbstractIn this work, a facile solvothermal synthesis of MnFe2O4 nanoparticles is followed by an easy and reproducible process to envelop the synthesized MnFe2O4 nanoparticles with iron oxide nanoparticles using ethanol and ethylene glycol as solvents. All prepared MnFe2O4 nanoparticles show a homogenous distribution of spherical particles with an average particle size between 12 and 16 nm. The encapsulation process of MnFe2O4 nanoparticles does not affect their homogenous distribution with a very thin layer of Fe3O4 on the shell structure. The magnetic properties showed a superparamagnetic character with enhanced magnetic properties of MnFe2O4@Fe3O4 compared to pure MnFe2O4, which has been verified by magnetization and electron spin resonance. The heating efficiency of the prepared samples was evaluated in terms of the specific loss power using the calorimetric method. The synthesized MnFe2O4 nanoparticles show a significantly high value of about 72 W/g, which got doubled in the core@shell structure and reached 140 W/g at 189 kHz and 10kA/m of the magnetic field.

AbstractBackgroundThe electrophysiological responses of the left atrial appendage (LAA) during pulsed‐field electrical isolation have not been established.ObjectiveThis study aims to investigate the electrical responses of the LAA during pulsed‐field electrical isolation using a novel device and their relations to acute isolation success.MethodsSix canines were enrolled. The E‐SeaLA™ device, which is able to perform LAA occlusion and ablation simultaneously, was deployed into the LAA ostium. LAA potentials (LAAp) were mapped via a mapping catheter, and the LAAp recovery time (LAAp RT, the time between the last pulsed spike and the first recovered LAAp) was measured after pulsed‐train delivery. The initial pulse index (PI, corelated to pulsed‐field intensity) was adjusted during the ablation procedure until LAAEI was achieved. Acute LAA electrical isolation (LAAEI) success was defined as LAAp disappearance or exit and entrance conduction block, confirmed through a drug test and a 60‐minute waiting period.ResultAll canines achieved successful LAA occlusion without peri‐device leaks. Acute LAA electrical isolation (LAAEI) was achieved in five out of six canines (5/6, 83.3%). Very late LAAp recurrence (LAAp RT > 600 s) was observed during PFA. Early recurrence (LAAp RT < 30 s) was observed in two canines (2/6, 33.3%) post‐PFA. Intermediate recurrence (LAAp RT ~ 120 s) was observed in three canines (3/6, 50%) post‐PFA. The two canines with intermediate recurrence achieved LAAEI with higher PI ablations. The one canine with early LAAp recurrence had a peri‐device leak and achieved LAAEI by the same PI after replacing with a larger size device and eliminating the peri‐device leak. Another canine with early recurrence (1/6, 16.7%) failed to achieve LAAEI due to epicardial connection with persistent left superior vena cava. No coronary spasm, stenosis or other complications were observed.ConclusionThese results suggest that with proper device‐tissue contact and pulse intensity, LAAEI can be achieved using this novel device without serious complications. The LAAp RT patterns observed in this study could inform and guide the adjustment of the ablation strategy.
Effects of intercropping marigold, cowpea and an insecticidal soap on whiteflies and aphids in organic squash
Authors: Lopez Marice , Liburd Oscar E. 
Published: June 2023

AbstractThe silverleaf whitefly MEAM1 (Bemisia tabaci) Gennadius (Hemiptera: Aleyrodidae), the cowpea aphid (Aphis craccivora Koch), the green peach aphid (Myzus persicae Sulzer) and the melon aphid (Aphis gossypii Glover) Hemiptera: Aphididae are major insect pests of squash (Cucurbita pepo L.), causing significant yield losses of up to 80% in Florida. We hypothesized that intercropping African marigold (Tagetes erecta L.) and cowpea (Vigna unguiculata L. Walp.) with zucchini squash will encourage an abundance of beneficial arthropods and increase cultural and biological control against these key insect pests by significantly reducing their populations and consequently improve yields. In a 2‐year field experiment, five treatments were evaluated in a randomized complete block design consisting of four replicates. Three diversified cropping treatments were implemented: (1) intercropping squash with marigold, (2) intercropping squash with cowpea, (3) intercropping squash with marigold and cowpea (mixed). These treatments were compared with an organic grower standard insecticide, (4) M‐Pede (potassium salts of naturally derived fatty acids) sprayed on monocropped squash and (5) monocropped squash with no pest management (control). Results indicated that squash intercropped with marigolds accounted for the highest marketable yields. Squash intercropped with cowpea had marginally high yields but attracted the highest densities of aphids. M‐Pede did not increase squash yields, but reduced aphids, whiteflies and associated squash silverleaf (SSL) disorder ratings and showed no deleterious effect on populations of natural enemies. We conclude that a mixture of marigold and cowpea could be used to suppress pests by increasing beneficial arthropod diversity while enhancing marketable yields of organic squash. M‐Pede could be used as a last resort when experiencing high hemipteran pressure.

AbstractTritrichomonas muris is a common flagellated protist isolated from the cecum of wild rodents. This commensal protist has been shown previously to alter immune phenotypes in laboratory mice. Other trichomonads, referred to as Tritrichomonas musculis and Tritrichomonas rainier, also naturally colonize laboratory mice and cause immune alterations. This report formally describes two new trichomonads, Tritrichomonas musculus n. sp., and Tritrichomonas casperi n. sp., at the ultrastructural and molecular level. These two protists were isolated from laboratory mice and were differentiated by their size and the structure of their undulating membrane and posterior flagellum. Analysis at the 18S rRNA and trans‐ITS genetic loci supported their designation as distinct species, related to T. muris. To assess the true extent of parabasalid diversity infecting laboratory mice, 135 mice bred at the National Institutes of Health (NIH) were screened using pan‐parabasalid primers that amplify the trans‐ITS region. Forty‐four percent of mice were positive for parabasalids, encompassing a total of eight distinct sequence types. Tritrichomonas casperi and Trichomitus‐like protists were dominant. T. musculus and T. rainier were also detected, but T. muris was not. Our work establishes a previously underappreciated diversity of commensal trichomonad flagellates that naturally colonize the enteric cavity of laboratory mice.
The environmental impact of keeping a tropical aquarium in Northern Europe
Authors: Perry William Bernard 
Published: June 2023

AbstractTropical fishkeeping is a popular practice in societies across the globe and involves recreating and sustaining an entire ecosystem in an aquarium within a domestic setting. The process invariably has an environmental impact, yet an assessment of this impact has previously been limited to the ecological consequences of harvesting fish from the wild or the release of non‐native fish species. Provided here are the first estimates of carbon dioxide equivalent (CO2eq) emissions produced from running a tropical aquarium across multiple countries in Northern Europe (France, Poland and the UK), along with water consumption. Estimates were produced in silico and are discussed in the context of freshwater and marine aquariums, calculated using example aquarium sizes of 50, 200 and 400 l. Using estimates from the UK, depending on size and running conditions, a tropical aquarium produces an estimated 85.3–635.2 kg of CO2eq per year, equating to 1.6%–12.4% of the UK annual average household CO2 emissions, and uses 156–31,200 l of water per year, equating to 0.2%–30.1% of the UK annual average household water usage. Despite this, comparison with the CO2eq of an average‐size dog (127–1592 kg of CO2eq per year) or cat (121–251 kg of CO2eq per year), estimated from meat consumption alone, demonstrates that ornamental fishkeeping can be a more environmentally conscious pet choice. In addition, the majority of CO2eq produced from tropical fishkeeping is generated from the energy consumption of aquarium equipment and as more national electricity grids begin to decarbonize, this estimate should decrease.

Published: June 2023

AbstractThe andrological study of a species involves the macro‐ and microscopic analyses of the internal reproductive organs and the evaluation of seminal parameters and ultrastructural characteristics of the spermatozoa. As in other vertebrates, the male reproductive tract in chondrichthyans consists of testes and reproductive ducts (efferent duct, epididymis, Leydig's gland, ductus deferens and seminal vesicle). In this study the authors used three adult specimens of Zapteryx brevirostris from wild capture kept at the Ubatuba Aquarium, Brazil. Semen was collected by abdominal massage over the location of the seminal vesicle, preceded by ultrasonographic evaluation. The semen collected was diluted 1:200 and subject to quantitative and morphological analyses. Ultrastructural analysis was performed using transmission and scanning electron microscopy. Correlation was observed between successful collection and ultrasonographic image of an engorged seminal vesicle, as well as testicles with easily delimitable margins and higher echogenicity. It was possible to identify free spermatozoa with helical filiform appearance, as well as spermatozeugmata. The average sperm concentration resulted in 5 million packets per millilitre and 140 million spermatozoa per millilitre. The sperm nucleus is described as follows: cone shaped, parachromatin sheath less dense than the chromatin of the nucleus, smooth depression of the nuclear fossa, abaxial axoneme 9 + 2 and accessory axonemal columns in positions 3 and 8 and oval shaped, with flattened inner surface in cross‐section. These results broaden the knowledge of the andrology of this species, contributing to ex situ breeding programmes.
Not a single meaning: Definition and evolution of singlehood in France and the United States
Authors: Bergström Marie , Brée Sandra 
Published: June 2023

AbstractSinglehood appears to be an understudied topic in the social sciences, and a particularly diverse field of research. Focusing on the United States and France, this article reviews existing literature to answer three questions that are prerequisites for theorizing singlehood (1) What is singlehood? We first discuss the diversity of terms used in ordinary language to designate singles, and the different statistical measures that coexist in the scholarly literature. (2) Who and how many are single? We show that different definitions lead to different counts of the single population and discuss the driving forces behind the rise in singlehood. (3) What is new? Drawing on literature on the couple norm and the single lifestyle, we then turn to the question of the specificity of the contemporary era. In the last section, we discuss the implications for theorizing singlehood. The answers to all three questions lead us to promote a life course approach to singlehood.

AbstractBackground and AimWe aim to conduct a systematic review and determine the association between obstructive sleep apnea (OSA) and gastroesophageal reflux disease (GERD).MethodsLiterature search for eligible studies was performed across major databases. The main endpoint was to assess the association between GERD and OSA. Subgroup analyses were performed to determine this strength of the association stratified by the diagnostic tools used for OSA (nocturnal polysomnogram or Berlin questionnaire) and GERD (validated reflux questionnaire or esophagogastroduodenoscopy). We also compared sleep efficiency, apnea hypopnea index, oxygen desaturation index, and Epworth Sleepiness Scale in OSA patients with or without GERD. Results were pooled together using Reviewer Manager 5.4.ResultsSix studies involving 2950 patients with either GERD or OSA were included in the pooled analysis. Our findings suggest that there was a statistically significant unidirectional association between GERD and OSA (odds ratio [OR] = 1.53, P = 0.0001). Subgroup analyses redemonstrated an OSA‐GERD association irrespective of the tools used for diagnosing either GERD or OSA (P = 0.24 and P = 0.82, respectively). Sensitivity analyses demonstrated the same association after controlling for gender (OR = 1.63), BMI (OR = 1.81), smoking (OR = 1.45), and alcohol consumption (OR = 1.79). In patients with OSA, there were no statistically significant differences between patients with or without GERD in terms of apnea hypopnea index (P = 0.30), sleep efficiency (P = 0.67), oxygen desaturation index (P = 0.39), and Epworth Sleepiness Scale (P = 0.07).ConclusionThere exists an association between OSA and GERD that is independent of the modalities used for screening or diagnosing both disorders. However, the presence of GERD did not affect the severity of OSA.

Published: June 2023

IntroductionDistress during pregnancy and postpartum is common and contributes to poor infant and maternal outcomes, such as developmental delays and mental health disorders, respectively. Anxiety sensitivity, or fear of the symptoms of anxiety (eg, palpitations, confusion), is a risk factor known to increase distress across psychological and health‐related conditions. Given the physiologic and emotional changes that occur during the perinatal period, anxiety sensitivity may be a salient risk factor for maternal distress. In this pilot study, we aimed to understand the unique role of prenatal anxiety sensitivity in postpartum psychological and parenting distress.MethodsTwenty‐eight pregnant women (mean age, 30.86 years) were recruited from the community in a Southeastern metropolitan area of the United States. Participants completed self‐report measures during their third trimester of pregnancy and again within 10 weeks postpartum. The Depression Anxiety and Stress Scales‐21 and the Parenting Distress subscale of the Parenting Stress Index‐4‐Short Form were the primary postpartum outcome measures.ResultsPrenatal anxiety sensitivity was elevated in this sample relative to convenience samples. Prenatal anxiety sensitivity uniquely contributed to postpartum psychological (b, 1.01; P < .001) and parenting distress (b, 0.62; P = .008), after accounting for age, gravidity, and gestation.DiscussionAlbeit preliminary, results suggest prenatal anxiety sensitivity may be an important and malleable risk factor associated with several mental health concerns common in the perinatal period. Anxiety sensitivity may be targeted with brief interventions to prevent or reduce postpartum distress. Reducing prenatal anxiety sensitivity has the potential prevent the onset or worsening of psychological disorders among women and, in turn, may improve infant and child outcomes. Future studies should replicate these findings in a larger sample.

AbstractTransgender consumers struggle to have their gender identity recognized, resorting to clothing as a practical way to forge their identity. Intimate apparel represents the innermost type of clothing, carrying both functional and aesthetic roles for transgender individuals. When navigating the intimate apparel marketplace, transgender consumers are faced with vulnerability as their gender identity is stigmatized by society, negatively impacting their well‐being. This research focuses on understanding the neglected aspects of intimate apparel consumption by transgender consumers, discussing the role of stigma as it generates vulnerability in the intimate apparel marketplace. To gain insight into the multifaceted transgender people's intimate apparel consumption context, we conducted in‐depth interviews with 18 Brazilian transgender consumers. Data were analyzed using dialogical thematic analysis with a hybrid approach of deductive and inductive coding. Our findings revealed that: (1) the consumption of intimate apparel by transgender individuals involves a striking duality of both positive and negative aspects; (2) although transgender consumers see intimate apparel as a legitimate way of expressing their gender identity that carries symbolic meaning, functional aspects (e.g., comfort and fit) are also essential to them; and (3) intimate apparel plays a unique role during transgender people's social transition as they can choose whether to use those pieces privately or publicly, unlike most fashion products. Our key takeaway from this research is that consuming intimate apparel carries multifaceted meanings for transgender consumers, impacting their emotional and social well‐being in several ways.

AbstractAimsTo examine registered nurses' attitudes about end‐of‐life care and explore the barriers and facilitators that influence the provision of high‐quality end‐of‐life care.DesignA sequential explanatory mixed methods research design was used.MethodsAn online cross‐sectional survey was distributed to 1293 registered nurses working in five different hospitals in the Kingdom of Saudi Arabia. The Frommelt Attitudes Towards Care of the Dying Scale was used to assess nurses' attitudes towards end‐of‐life care. Following the survey, a subset of registered nurses were interviewed using individual semi‐structured interviews.ResultsFour hundred and thirty‐one registered nurses completed the online survey, and 16 of them participated in individual interviews. Although nurses reported positive attitudes towards caring for dying patients and their families in most items, they identified negative attitudes towards talking with patients about death, their relationship with patients' families and controlling their emotions. The individual interview data identified the barriers and facilitators that registered nurses experience when providing end‐of‐life care. Barriers included a lack of communication skills and family and cultural and religious resistance to end‐of‐life care. The facilitators included gaining support from colleagues and patients' families.ConclusionThis study has identified that while registered nurses hold generally favourable attitudes towards end‐of‐life care, they have negative attitudes towards talking with patients and families about death and managing their emotional feelings.Relevance to clinical practiceEducation providers and leaders in healthcare settings should consider developing programmes for undergraduate nurses and nurses in clinical practice to raise awareness about the concept of death in a cross‐section of cultures. Nurses' attitudes towards dying patients will be enhanced with culture‐specific knowledge which will also enhance communication and coping methods.Reporting methodThis study used the Mixed Methods Article Reporting Standards (MMARS).
