The Effect of Long Term Captivity on Stress Levels in Anolis carolinensis Lizards

ABSTRACT The effect of long term captivity is a factor that is important for all research utilizing wild caught animals. Despite the fact that it can be considered to be one of the most fundamental potential sources of stress in captivity, it has received a low amount of interest in recent research on lizards. Given the wide variety in ecology and life history among lizards species, it would make sense to investigate the effect of long term captivity on wild caught lizards on a broader scale. In this study we investigated the effect of long term captivity (four months) on the physiology and behavior of male and female Anolis carolinensis lizards. Our results showed no negative effects of four months of captivity on physiological and behavioral measurements in male A carolinensis lizards. Similar results for females were found for all measurements except body mass and tail width. Here our results indicated a potential negative effect of four months of captivity on body mass and tail width in females.
Circulating Small Extracellular Vesicles Activate TYRO3 to Drive Cancer Metastasis and Chemoresistance

These findings demonstrate that circulating extracellular vesicles are a novel driver in migration and survival of aggressive cancer cells via TYRO3 activation. Extracellular vesicles (EV) in the tumor microenvironment have emerged as crucial mediators that promote proliferation, metastasis, and chemoresistance. However, the role of circulating small EVs (csEV) in cancer progression remains poorly understood. In this study, we report that csEV facilitate cancer progression and determine its molecular mechanism. csEVs strongly promoted the migration of cancer cells via interaction with phosphatidylserine of csEVs. Among the three TAM receptors, TYRO3, AXL, and MerTK, TYRO3 mainly interacted with csEVs. csEV-mediated TYRO3 activation promoted migration and metastasis via the epithelial–mesenchymal transition and stimulation of RhoA in invasive cancer cells. Additionally, csEV–TYRO3 interaction induced YAP activation, which led to increased cell proliferation and chemoresistance. Combination treatment with gefitinib and KRCT-6j, a selective TYRO3 inhibitor, significantly reduced tumor volume in xenografts implanted with gefitinib-resistant non–small cell lung cancer cells. The results of this study show that TYRO3 activation by csEVs facilitates cancer cell migration and chemoresistance by activation of RhoA or YAP, indicating that the csEV/TYRO3 interaction may serve as a potential therapeutic target for aggressive cancers in the clinic. Significance: These findings demonstrate that circulating extracellular vesicles are a novel driver in migration and survival of aggressive cancer cells via TYRO3 activation.

Topical timolol 0.5% as the primary treatment of ophthalmic pyogenic granuloma: A prospective, single-arm study

Purpose: To study topical timolol (0.5%) as a first-line treatment in ophthalmic pyogenic granuloma (PG) in terms of safety and efficacy. Methods: This was a prospective, interventional, single-arm study conducted at a tertiary eye care hospital in central India. Only new cases of PG were counseled to get enrolled in the study. A total of 40 patients were analyzed in the study. Topical timolol eye drop (0.5%) was started in each patient twice daily for 4–6 weeks duration. The patients were divided into five categories according to the percentage reduction in the size of PG as follows: i) 80–100% reduction - excellent responders, ii) 60–80% – good, iii) 40–60% – satisfactory, iv) 20–40% – poor, and v) <20% – very poor/nonresponder. After 6 months of starting treatment final evaluation was done. Results: The mean age of the patients was 23.5 ± 13.3 years. Etiology of the disease included chalazion (n = 11, 27.5%), trauma (n = 2, 5%), surgery (n = 7, 17.5%), foreign body (n = 2, 5%), and idiopathic (n = 18, 45%). An excellent response was achieved in 31 (77.5%) patients. Twenty-seven (67.5%) patients had complete resolution of lesions within 6 weeks. Recurrence of the lesion was not noticed in any patients. Conclusion: Timolol 0.5% in topical form is a good treatment option for ophthalmic PG in all age groups. The treatment has no adverse effects when given to suitable individuals for a limited period.
Small‐scale hypoxic cultures for monitoring the spatial reorganization of glycolytic enzymes in Saccharomyces cerevisiae

At normal oxygen concentration, glycolytic enzymes are scattered in the cytoplasm of Saccharomyces cerevisiae. Under hypoxia, however, most of these enzymes, including enolase, pyruvate kinase, and phosphoglycerate mutase, spatially reorganize to form cytoplasmic foci. We tested various small‐scale hypoxic culture systems and showed that enolase foci formation occurs in all the systems tested, including in liquid and on solid media. Notably, a small‐scale hypoxic culture in a bench‐top multi‐gas incubator enabled the regulation of oxygen concentration in the media and faster foci formation. Here, we demonstrate that the foci formation of enolase starts within few hours after changing the oxygen concentration to 1% in a small‐scale cultivation system. The order of foci formation by each enzyme is tightly regulated, and of the three enzymes, enolase was the fastest to respond to hypoxia. We further tested the use of the small‐scale cultivation method to screen reagents that can control the spatial reorganization of enzymes under hypoxia. An AMPK inhibitor, dorsomorphin, was found to delay formation of the foci in all three glycolytic enzymes tested. These methods and results provide efficient ways to investigate the spatial reorganization of proteins under hypoxia to form a multienzyme assembly, the META body, thereby contributing to understanding and utilizing natural systems to control cellular metabolism via the spatial reorganization of enzymes.
LncRNA NEAT1 accelerates renal tubular epithelial cell damage by modulating mitophagy via miR‐150‐5p–DRP1 axis in diabetic nephropathy

What is the central question of this study? Diabetic nephropathy (DN) is a severe complication of diabetes correlated with a higher mortality rate in diabetic patients. Renal tubular injury participates in the pathogenesis of DN. We aimed to uncover the biological function of the NEAT1–miR‐150‐5p–DRP1 axis in an in vitro model of DN and elaborate the potential mechanisms. What is the main finding and its importance? NEAT1 facilitated high glucose‐induced damage in HK‐2 cells by reducing mitophagy via the miR‐150‐5p–DRP1 axis, which sheds light on DN pathogenesis and reveals a potential treatment for DN.
Field testing an “acoustic lighthouse”: Combined acoustic and visual cues provide a multimodal solution that reduces avian collision risk with tall human-made structures

Billions of birds fatally collide with human-made structures each year. These mortalities have consequences for population viability and conservation of endangered species. This source of human-wildlife conflict also places constraints on various industries. Furthermore, with continued increases in urbanization, the incidence of collisions continues to increase. Efforts to reduce collisions have largely focused on making structures more visible to birds through visual stimuli but have shown limited success. We investigated the efficacy of a multimodal combination of acoustic signals with visual cues to reduce avian collisions with tall structures in open airspace. Previous work has demonstrated that a combination of acoustic and visual cues can decrease collision risk of birds in captive flight trials. Extending to field tests, we predicted that novel acoustic signals would combine with the visual cues of tall communication towers to reduce collision risk for birds. We broadcast two audible frequency ranges (4 to 6 and 6 to 8 kHz) in front of tall communication towers at locations in the Atlantic migratory flyway of Virginia during annual migration and observed birds’ flight trajectories around the towers. We recorded an overall 12–16% lower rate of general bird activity surrounding towers during sound treatment conditions, compared with control (no broadcast sound) conditions. Furthermore, in 145 tracked “at-risk” flights, birds reduced flight velocity and deflected flight trajectories to a greater extent when exposed to the acoustic stimuli near the towers. In particular, the 4 to 6 kHz stimulus produced the greater effect sizes, with birds altering flight direction earlier in their trajectories and at larger distances from the towers, perhaps indicating that frequency range is more clearly audible to flying birds. This “acoustic lighthouse” concept reduces the risk of collision for birds in the field and could be applied to reduce collision risk associated with many human-made structures, such as wind turbines and tall buildings.
Dental Arch Relationship Outcomes Following 2-Stage Palatoplasty for Japanese Patients With Complete Unilateral Cleft Lip and Palate: A 3-Center Study

Objective: To compare dental arch relationship outcomes following 3 different 2-stage palatal repair protocols. Design: Retrospective, cross sectional. Setting: Three cleft palate centers (A, B, C) in Japan. Patients: Ninety (A: 39, B: 26, C: 25) consecutively treated Japanese patients with complete unilateral cleft lip and palate. Interventions: In A, the soft palate and the posterior half of the hard palate were repaired at a mean age of 1 year 7 months. In B, the soft palate and hard palate were closed separately at a mean age of 1 year 6 months and 5 years 8 months, respectively. In C, the soft palate and hard palate were closed at a mean age of 1 year and 1 year 5 months, respectively. Main Outcome Measures: Dental arch relationships were assessed using the 5-Year-Olds’ (5-Y) index by 5 raters and the Huddart/Bodenham (HB) index by 2 raters. Results: Intra- and inter-rater reliabilities showed substantial or almost perfect agreement for the 5-Y and HB ratings. No significant differences in mean values and distributions of 5-Y scores were found among the 3 centers. The mean HB index scores of molars on the minor segment were significantly smaller in C than those in A and B (P < .05). Conclusions: There were no significant differences in dental arch relationships at 5 years among the times and techniques of hard palate closure. However, further analysis of the possible influence of infant cleft size as a covariable on a larger sample size is needed.
Weed-infecting viruses in a tropical agroecosystem present different threats to crops and evolutionary histories

In the Caribbean Basin, malvaceous weeds commonly show striking golden/yellow mosaic symptoms. Leaf samples from Malachra sp. and Abutilon sp. plants with these symptoms were collected in Hispaniola from 2014 to 2020. PCR tests with degenerate primers revealed that all samples were infected with a bipartite begomovirus, and sequence analyses showed that Malachra sp. plants were infected with tobacco leaf curl Cuba virus (TbLCuCV), whereas the Abutilon sp. plants were infected with a new bipartite begomovirus, tentatively named Abutilon golden yellow mosaic virus (AbGYMV). Phylogenetic analyses showed that TbLCuCV and AbGYMV are distinct but closely related species, which are most closely related to bipartite begomoviruses infecting weeds in the Caribbean Basin. Infectious cloned DNA-A and DNA-B components were used to fulfilled Koch’s postulates for these diseases of Malachra sp. and Abutilon sp. In host range studies, TbLCuCV also induced severe symptoms in Nicotiana benthamiana, tobacco and common bean plants; whereas AbGYMV induced few or no symptoms in plants of these species. Pseudorecombinants generated with the infectious clones of these viruses were highly infectious and induced severe symptoms in N. benthamiana and Malachra sp. , and both viruses coinfected Malachra sp. , and possibly facilitating virus evolution via recombination and pseudorecombination. Together, our results suggest that TbLCuCV primarily infects Malachra sp. in the Caribbean Basin, and occasionally spills over to infect and cause disease in crops; whereas AbGYMV is well-adapted to an Abutilon sp. in the Dominican Republic and has not been reported infecting crops.
Preventing internalising problems in preschoolers with chronic physical health conditions

This pilot study aimed to explore the suitability of a preventative intervention for internalising problems in young children with chronic physical health conditions. The pilot study focused on a subsample of 27 children with chronic physical health conditions within a population-level randomised controlled trial of the Cool Little Kids parenting programme. The Cool Little Kids parenting programme aims to prevent the development of internalising problems in inhibited (shy/anxious) preschool children by educating parents to reduce young children’s avoidant coping styles and manage their anxiety/distress. The wider trial recruited 545 temperamentally inhibited preschool children. Measures included child health/development concerns and internalising symptoms at baseline, feedback on Cool Little Kids post-intervention and child internalising problems at one- and two-year longitudinal follow-up. At baseline, inhibited children with and without chronic physical health conditions had levels of internalising symptoms above the normative mean. At post-intervention, parents of children with chronic physical health conditions gave feedback that Cool Little Kids was helpful for managing their child’s emotional distress. At follow-up, significantly fewer intervention than control children with chronic physical health conditions had specific phobia after 1 year (25% vs 70%) and specific fear symptoms after 2 years (mean 9.57 vs 16.89). As the pilot findings are promising, a further trial of Cool Little Kids in a physical health treatment service with a larger sample of children with chronic physical illness diagnoses would be worthwhile.
An Attention-Based Deep Learning Approach for Sleep Stage Classification With Single-Channel EEG

Automatic sleep stage mymargin classification is of great importance to measure sleep quality. In this paper, we propose a novel attention-based deep learning architecture called AttnSleep to classify sleep stages using single channel EEG signals. This architecture starts with the feature extraction module based on multi-resolution convolutional neural network (MRCNN) and adaptive feature recalibration (AFR). The MRCNN can extract low and high frequency features and the AFR is able to improve the quality of the extracted features by modeling the inter-dependencies between the features. The second module is the temporal context encoder (TCE) that leverages a multi-head attention mechanism to capture the temporal dependencies among the extracted features. Particularly, the multi-head attention deploys causal convolutions to model the temporal relations in the input features. We evaluate the performance of our proposed AttnSleep model using three public datasets. The results show that our AttnSleep outperforms state-of-the-art techniques in terms of different evaluation metrics. Our source codes, experimental data, and supplementary materials are available at https://github.com/emadeldeen24/AttnSleep.
Medication therapy management in dermatology: a call to action

BACKGROUND Medication therapy management services are effective at increasing patient adherence, alleviating physician burden, and reducing health care expenditures. However, dermatologic disease are not included in the criteria. OBJECTIVE We advocate for the incorporation of dermatologic disease into the eligibility criteria for medication therapy management services, as non-adherence remains a significant cause of treatment failure. RESULTS Studies have suggested that medication therapy management will be beneficial for chronic dermatologic diseases including psoriasis and atopic dermatitis. CONCLUSIONS We believe expanding MTM services for dermatology patients would be well-received by healthcare professionals and patients alike.
Visualization of X chromosome reactivation in mouse primordial germ cells in vivo

ABSTRACT X chromosome inactivation (XCI), determined during development, remains stable after embryonic cell divisions. However, primordial germ cells (PGCs) are exceptions in that XCI is reprogrammed and inactivated X chromosomes are reactivated. Although interactions between PGCs and somatic cells are thought to be important for PGC development, little is known about them. Here, we performed imaging of X chromosome reactivation (XCR) using the ‘Momiji’ mouse system, which can monitor the X chromosome's inactive and active states using two color fluorescence reporter genes, and investigated whether interactions would affect XCR in PGCs. Based on their expression levels, we found that XCR of the Pgk1 locus began at embryonic day (E)10.5 and was almost complete by E13.5. During this period, PGCs became distributed uniformly in the genital ridge, proliferated, and formed clusters; XCR progressed accordingly. In addition, XCR of the Pgk1 locus preceded that of the Hprt locus, indicating that the timing of epigenetic memory erasure varied according to the locus of each of these X-linked genes. Our results indicate that XCR proceeds along with the proliferation of PGCs clustered within the genital ridge. This article has an associated First Person interview with the first author of the paper.
Estimation of Degradation Velocity of Biocompatible Damaged Stents due to Blood Flow

Objective: Bioresorbable materials represent a promising technology for the treatment of coronary disease. Among the different materials employed, magnesium stents display favourable mechanical properties. One of the main uncertainties regarding use is their behaviour when deployed on coronary bifurcations, especially when their retardant coating has been damaged during the implantation process. This paper analyses the temporal evolution of the degradation of a damaged magnesium stent inserted into a coronary bifurcation. Methods: The rate of erosion-corrosion and the effect of the flow configuration on the mass transfer coefficient were estimated on the basis of previous experimental studies and numerical simulations. This coefficient has been employed to reproduce the conditions that can appear in real stent configurations, and computational fluid dynamics simulations were performed. Results: The diffusion coefficient for this particular case has been calculated from the mass transfer coefficient and the Sherwood number. The results of the simulation show how the presence of the inner artery wall has a positive effect, preventing a premature degradation of the stent, and how the distal strut is protected by the presence of the proximal struts. Conclusions: This study demonstrates the usefulness of the proposed methodology to evaluate the temporal evolution of the degradation of struts made of magnesium alloys. In addition, this methodology can be applied to a study of different materials and geometric configurations. Significance: The proposed technique can contribute to expanding existing knowledge concerning bioresorbable stent flow-corrosion, thus improving their design and implantation.
Short chain fatty acids released by Fusobacterium nucleatum are neutrophil chemoattractants acting via free fatty acid receptor 2 (FFAR2)

Fusobacterium nucleatum is a gram‐negative and anaerobic oral commensal that is implicated in inflammatory conditions of the tooth‐supporting structures, that is, periodontal diseases. One of the main characteristics of these conditions is an accumulation of neutrophil granulocytes in the gingival pockets where bacteria reside. Neutrophils are recruited to tissue‐residing microbes by gradients of bacteria derived chemoattractants, and the cellular migration over the pocket epithelium into the gingival pocket is likely governed by chemoattractants released by the amino acid fermenting anaerobes typically colonising this site. However, the chemoattractants released by F. nucleatum and other oral anaerobes have long been unidentified. In the present study, we show that the major chemoattractants released during the growth of F. nucleatum are short chain fatty acids (SCFAs), primarily acetate and butyrate. These SCFAs, that are released at high levels as end‐products of the metabolism of F. nucleatum, trigger chemotaxis of human neutrophils, as well as cytosolic Ca2+ signals, via free fatty acid receptor 2 (FFAR2). This finding establishes the SCFA‐FFAR2 interaction as an important mechanism in the recruitment of neutrophils to the periodontal pocket, but could also be of importance in the pathogenesis of other medical conditions involving colonisation/infection of F. nucleatum.
Sequencing of Coastal Lagoon Samples from the Piñones Lagoon, Puerto Rico, Reveals Important Role of Bacterial Sulfur Metabolism in the Lagoon Ecosystem

This initial microbial analysis of the Piñones lagoon shows a high representation of sulfur-oxidizing Sulfurimonas and sulfur-reducing Sulfurospirillum bacteria. These species are likely responsible for maintaining sulfur homeostasis and prevent the buildup of toxic sulfur components, but may contribute to nitrogen buildup, in the mangrove ecosystem.

Draft Genome Sequence of Bacillus albus Strain IB84, Isolated from Mexican Soil

Bacillus albus is a new species, but it lies on the borderline with Bacillus thuringiensis. In this work, we report a strain previously identified as Bacillus thuringiensis IB84, which now, based on average nucleotide identity and rRNA 16S, gyrB, groEL, and XRE gene sequences, must be identified as Bacillus albus.

A risk-based approach for managing hydraulic fracturing–induced seismicity

Varying the stop lights Traffic light protocols can help to mitigate induced earthquakes from unconventional oil production. However, they are not geographically tuned to account for how shaking may actually translate to structural damage. Schultz et al. incorporated damage tolerance into a traffic light protocol for the Eagle Ford shale play. They found that shut-off may be necessary more quickly in populated regions, whereas sparsely populated areas of the play can take up to a magnitude 5 earthquake without issue. This risk-based strategy provides a more nuanced approach to regulating induced seismicity. Science, this issue p. 504 Accounting for risk provides a more nuanced traffic light protocol for regulating induced seismicity. Risks from induced earthquakes are a growing concern that needs effective management. For hydraulic fracturing of the Eagle Ford shale in southern Texas, we developed a risk-informed strategy for choosing red-light thresholds that require immediate well shut-in. We used a combination of datasets to simulate spatially heterogeneous nuisance and damage impacts. Simulated impacts are greater in the northeast of the play and smaller in the southwest. This heterogeneity is driven by concentrations of population density. Spatially varying red-light thresholds normalized on these impacts [moment magnitude (Mw) 2.0 to 5.0] are fairer and safer than a single threshold applied over a broad area. Sensitivity tests indicate that the forecast maximum magnitude is the most influential parameter. Our method provides a guideline for traffic light protocols and managing induced seismicity risks.
