Influence of environmental factors and body condition on the post-oviposition behavior in the emerald glass frog Espadarana prosoblepon (Centrolenidae)
Authors: Goyes Vallejos Johana , Hernández-Figueroa Abner D. 
Published: June 2022

In species with parental care behaviors, parents may adjust the intensity and duration of their care if fluctuation in factors such as environmental variables or body condition affects offspring survival. In the face of environmental changes, many egg-laying species remain with their clutch for extended periods if this behavioral adjustment provides tangible benefits to the offspring. However, the length of time parents stay with the offspring may also differ depending on the individual’s body condition. In the glass frog family (Centrolenidae), several species exhibit long-term egg attendance in which they remain with their clutch for several days after oviposition takes place. For some of them, changes in environmental variables lead to increased parental care efforts. For the species in which parents remain with their offspring for a short period (less than 24 hours), it is less clear if this constitutes parenting behavior, and whether parents adjust their efforts as a function of environmental change or the parent’s body condition remains unexplored. We studied a population of the Emerald Glass Frog, Espadarana prosoblepon, a species that exhibits a short period of quiescence after oviposition (less than three hours). Our study aimed to determine whether females alter the length of their post-oviposition quiescence period in response to changes in environmental variables (i.e., temperature, humidity, rainfall, and mean wind speed) or female body condition. Pairs in amplexus were captured in the field and transported to semi-natural enclosures to record the duration of post-oviposition quiescence using infrared cameras. Females’ post-oviposition quiescence lasted an average of 67.4 ± 26.6 min (range = 22.7–158.3 min). We did not find a significant relationship between the duration of the post-oviposition quiescence and any of the environmental variables tested. Similarly, post-oviposition quiescence duration was not influenced by female body condition. Because the variation observed in the duration of post-oviposition quiescence was not related to changes in extrinsic (environmental) or intrinsic (body condition) factors, we found no evidence that females of E. prosoblepon modify their post-oviposition behavior in response to any of the variables examined in this study. Future research investigating the adaptive significance of the post-oviposition quiescence observed in this species is needed to understand how this behavior is related to parental care efforts.

Published: June 2022

Aims: In past, labour was extensively used in agriculture sector and there was huge surplus labour in agriculture sector. However, such trend has recently been changed where surplus labour in agricultural sector has reduced significantly and agriculture sector compete with non-agricultural sector in terms of hiring labour. Thus, the present study was undertaken to analyze the determinants of labour migration from agriculture sector to non-agricultural sector in Gopalganj district of Bangladesh.
Place and Duration of Study: The study was conducted at 12 villages of three upazilas (Gopalganj Sadar, Tungipara and Kotalipara) in Gopalganj district. For the study, data were collected during the period from January to March in 2021.
Methodology: To this end, primary data were collected from agricultural labours. Descriptive statistics and simple random sampling technique were used in this study. Binary logistic model was used to analyze the collected data. In addition, five point likert scale was used to rank the barrier towards internal labour migration.
Results: Results found from the logit model indicate that factors like family size, education, past experience, access to available information, transportation facilities, and savings are positively related with the log of odd ratio in favor of labour migration from agriculture sector to non-agricultural sector while wage rate, age, off-farm income and farm holdings are inversely related with labour transfer from agriculture sector to non-agricultural sector. In addition, respondents in the study area have recognized lack of proper technical training as the major constraint in labour migration with a mean value of 4.48.
Conclusion: The present study recommends that government should take initiatives to open skill development institutions in rural level so that agricultural labour can take training. Regarding necessary information on non-agricultural jobs, it can be recommended that government, local agents and NGOs, in case of migration, should take proper initiatives so that agricultural labours can easily get information about non-agricultural jobs.

AbstractElectrochromic (EC) glazing reduces the cooling load via solar radiation shielding. However, excessive solar radiation shielding increases the heating load. In other words, the energy‐saving effect of EC glazing is dependent on the energy performance of the building. This study compares the heating and cooling loads reduction effects of static and EC glazing under various conditions to evaluate the regional applicability of EC glazing in Japan. Furthermore, to maximize the effect, we employ a machine learning (ML)‐based operation and evaluate its efficiency. A parametric study is conducted based on a standard office model in Japan using the DesignBuilder software. The result shows that the heating and cooling loads reduces by 17.1% compared with low‐E glazing in warm climates (Miyazaki, Zone 7). However, in cold climates (Obihiro, Zone 2), the energy increase is 25.4% and the trend of the effect changes near Zone 4. Therefore, on days when the heating load is expected to occur in Zones 3–5, we incorporate solar heat before working hours. The results show that reduction in heating and cooling loads of 2–3% can be expected and that the operation schedule can be set accurately via ML.

ObjectiveTo determine if single‐nucleotide polymorphisms (SNPs) in DNA repair genes are enriched in individuals with systemic lupus erythematosus (SLE) and if they are sufficient to confer a disease phenotype in a mouse model.MethodsHuman exome chip data of 2499 patients with SLE and 1230 healthy controls were analyzed to determine if variants in 10 different mismatch repair genes (MSH4, EXO1, MSH2, MSH6, MLH1, MSH3, POLH, PMS2, ML3, and APEX2) were enriched in individuals with SLE. A mouse model of the MSH6 SNP, which was found to be enriched in individuals with SLE, was created using CRISPR/Cas9 gene targeting. Wildtype mice and mice heterozygous and homozygous for the MSH6 variant were then monitored for 2 years for the development of autoimmune phenotypes, including the presence of high levels of antinuclear antibodies (ANA). Additionally, somatic hypermutation frequencies and spectra of the intronic region downstream of the VHJ558‐rearranged JH4 immunoglobulin gene was characterized from Peyer's patches.ResultsBased on the human exome chip data, the MSH6 variant (rs63750897, p.Ser503Cys) is enriched among patients with SLE versus controls after we corrected for ancestry (odds ratio = 8.39, P = 0.0398). Mice homozygous for the MSH6 variant (Msh6S502C/S502C) harbor significantly increased levels of ANA. Additionally, the Msh6S502C/S502C mice display a significant increase in the infiltration of CD68+ cells (a marker for monocytes and macrophages) into the lung alveolar space as well as apoptotic cells. Furthermore, characterization of somatic hypermutation in these mice reveals an increase in the DNA polymerase η mutational signature.ConclusionAn MSH6 mutation that is enriched in humans diagnosed with lupus was identified. Mice harboring this Msh6 mutation develop increased autoantibodies and an inflammatory lung disease. These results suggest that the human MSH6 variant is linked to the development of SLE.

AbstractIn recent years, 3D printing of electronics have received growing attention due to their potential applications in emerging fields such as nanoelectronics and nanophotonics. Multiphoton lithography (MPL) is considered the state‐of‐the‐art amongst the microfabrication techniques with true 3D fabrication capability owing to its excellent level of spatial and temporal control. Here, a homogenous and transparent photosensitive resin doped with an organic semiconductor material (OS), which is compatible with MPL process, is introduced to fabricate a variety of 3D OS composite microstructures (OSCMs) and microelectronic devices. Inclusion of 0.5 wt% OS in the resin enhances the electrical conductivity of the composite polymer about 10 orders of magnitude and compared to other MPL‐based methods, the resultant OSCMs offer high specific electrical conductivity. As a model protein, laminin is incorporated into these OSCMs without a significant loss of activity. The OSCMs are biocompatible and support cell adhesion and growth. Glucose‐oxidase‐encapsulated OSCMs offer a highly sensitive glucose sensing platform with nearly tenfold higher sensitivity compared to previous glucose biosensors. In addition, this biosensor exhibits excellent specificity and high reproducibility. Overall, these results demonstrate the great potential of these novel MPL‐fabricated OSCM devices for a wide range of applications from flexible bioelectronics/biosensors, to nanoelectronics and organ‐on‐a‐chip devices.

AbstractRadical reduction of III–V device costs requires a multifaceted approach attacking both growth and substrate costs. Implementing device removal and substrate reuse provides an opportunity for substrate cost reduction. Controlled spalling allows removal of thin devices from the expensive substrate; however, the fracture‐based process currently generates surfaces with significant morphological changes compared to polished wafers. 49 single junction devices are fabricated across the spalled surface of full 50 mm germanium wafers without chemo‐mechanical polishing before epitaxial growth. Device defects are identified and related to morphological spalling defects—arrest lines, gull wings, and river lines—and their impact on cell performance using physical and functional characterization techniques. River line defects have the most consistent and detrimental effect on cell performance. Devices achieve a single junction efficiency above 23% and open‐circuit voltage of 1.01 V, demonstrating that spalled germanium does not need to be returned to a pristine, polished state to achieve high‐quality device performance.

AbstractAgenesis of Corpus Callosum, Cardiac, Ocular, and Genital Syndrome (ACOGS; OMIM #618929) is a rare genetic disorder characterized by global developmental delay, agenesis or hypoplasia of corpus callosum, craniofacial dysmorphism, ocular, cardiac, and genital anomalies. ACOGS is caused by variations in the CDH2 gene. Our patient had a novel finding besides the classical findings of ACOGS. To the best of our knowledge, only 14 patients with ACOGS have been reported. Here, we reported the fifteenth patient with ACOGS, having a novel de novo nonsense variant in the CDH2 gene, and the first patient from Turkey with a novel finding. Our patient was the first female to have a renal anomaly since only genital malformations were reported in male patients (cryptorchidism, micropenis) so far.

AbstractElectrospun nanofibers have gained much attention for enzyme immobilization due to their high surface‐to‐volume ratio. In this study, urease was immobilized on chitosan/poly(vinyl alcohol) (PVA) nanofibers by both adsorption and crosslinking methods. In order to obtain nanofibers with more desirable properties, solutions with different ratios of chitosan and PVA were electrospun and crosslinked using glutaraldehyde. Comparing SEM images of the nanofibers, before and after immersing them in phosphate buffer, it was shown that higher chitosan content leads to more stable fibers. So, the solution with the chitosan to PVA ratio of 40:60 was used for enzyme immobilization. Then, the effects of initial protein concentration, temperature, incubation time, and method of immobilization were investigated to reach the highest enzyme activity. Under similar immobilization conditions, covalently immobilized urease showed higher activity, compared to uncrosslinked immobilized enzyme. Besides, it retained 30% of its initial activity after 10 times usage. So, this method was chosen for further investigation. Not only the activity of the immobilized enzyme was much higher than the free enzyme in a wide range of pH and temperature, but also stability of the immobilized enzyme was improved. Immobilized urease was then used to remove thiourea which is a toxic compound. Findings indicated 60% hydrolysis of initial thiourea in 12 h. In conclusion, the findings showed that chitosan/PVA nanofibers are suitable candidates for the immobilization of urease.
Source‐enhanced prototypical alignment for single image 3D model retrieval

Published: June 2022

AbstractSingle image 3D model retrieval has attracted a lot of attentions with the convenience of organizing large‐scale unlabeled 3D models. Existing methods transfer the knowledge from well‐annotated 2D images (i.e., source domain) to unlabeled 3D models (i.e., target domain) to improve the discriminability of 3D models and align the feature distributions of 2D images and 3D models. However, during the alignment, the feature learning target of improving the discriminability of 3D models sometimes confuses the boundaries between 2D image categories, where prior methods ignore keeping the discriminability of 2D images. Motivated by this observation, we propose a source‐enhanced prototypical alignment framework to first remain the discriminability of 2D images and then guide the category‐level cross‐domain alignment with better image representations. Specifically, a novel separation and compactness loss is proposed for images to separate the samples from different categories and compact the samples within the same category. Then we perform prototypical alignment to make 2D image features assist in the discriminative feature learning for 3D models. We evaluate the proposed method on the commonly used cross‐domain 3D model retrieval benchmarks, namely MI3DOR and MI3DOR‐2, and the results demonstrate the effectiveness of the proposed method.

Published: June 2022

AbstractVarying levels of sensitivity to florpyrauxifen‐benzyl and benzobicyclon applications among rice (Oryza sativa L.) cultivars have been observed. The safe use of florpyrauxifen‐benzyl and benzobicyclon in the same herbicide program could provide broad‐spectrum weed control and delay resistance in weed species. Two experiments were conducted in 2019 and 2020 near Stuttgart, AR, to test cultivars’ sensitivity to multiple rates of florpyrauxifen‐benzyl and applications of florpyrauxifen‐benzyl followed by benzobicyclon. The first experiment was designed to determine the sensitivity of the rice cultivars ‘XP753’, ‘CL XL745’, ‘Gemini 214CL’, ‘Titan’, and ‘Diamond’ to applications of florpyrauxifen‐benzyl at 0.03 and 0.06 lb acid equivalent (a.e.) acre–1 and sequential applications of 0.03 lb a.e. acre–1. The second experiment determined the effect of benzobicyclon applied post‐flood on rice injury following an application of florpyrauxifen‐benzyl on the same cultivars used in the previous experiment. A rough rice yield loss of 17% was observed for sequential applications of florpyrauxifen‐benzyl at 0.03 lb a.e. acre–1 to XP753. Single applications of florpyrauxifen‐benzyl at 0.06 lb a.e. acre–1 caused a 45% groundcover reduction in XP753, whereas sequential applications of 0.03 lb a.e. acre–1 reduced groundcover on all hybrid cultivars tested. Applications of benzobicyclon alone never injured rice by more than 8%, and applying benzobicyclon after florpyrauxifen‐benzyl did not increase the observed injury over florpyrauxifen‐benzyl alone. Single applications of florpyrauxifen‐benzyl followed by benzobicyclon can be used in an herbicide program to control weeds without the risk of greater injury than is typically caused by florpyrauxifen‐benzyl alone.

AbstractExcipient allergies are rare and difficult to diagnose. Carboxymethylcellulose (CMC, carmellose sodium) is an anionic water‐soluble polymer derived from native cellulose, that is, used as an excipient. Here, we report a case of urticaria caused by the CMC in lidocaine jelly and dimethicone drops, which had used for upper gastrointestinal endoscopy. CMC is widely used in pharmaceutical preparations, food additives, and other pharmaceuticals, and its use is increasing. However, there are few reports on immediate hypersensitivity reactions because substances containing CMC. Previous reports and our case suggest that excipients, such as CMC, can be potential hidden allergens.

AbstractEine zentrale Implikation naturwissenschaftlicher Grundbildung ist die Befähigung von Schüler:innen, auf Grundlage ihres erworbenen naturwissenschaftlichen Wissens an Diskursen und Entscheidungsprozessen um gesellschaftliche Herausforderungen, etwa dem Klimawandel, zu partizipieren. Um entsprechende Kompetenzen vermitteln zu können, bedarf es Chemielehrer:innen, die selbst an den gesellschaftlich relevanten Diskursen partizipieren können, in einem wissenschaftsgerechten Umgang mit Daten‐ und Informationsquellen angeleitet wurden, sowie in der Lage sind, gesellschaftliche Herausforderungen in die unterrichtliche Praxis zu transformieren. Dazu ist ein Bildungsangebot für Chemielehramtsstudierende konzipiert worden, welches Diskurse von Emissionen der Oxide des Kohlenstoffs und Stickstoffs in den Blick nahm. In einem qualitativen Setting wurden die Entwicklungen von Chemielehramtsstudierenden im Laufe des Seminars erforscht.
