Abstract
Background
Ictalurus is one of the most representative groups of North American freshwater fishes. Although this group has a well-studied fossil record, and has been the subject of several morphological and molecular phylogenetic studies, incomplete taxonomic sampling and insufficient taxonomic studies have produced a rather complex classification along with intricate evolutionary history patterns of the genus that are considered unresolved and remain under debate.
Results
Based on four loci and the most comprehensive taxonomic sampling analyzed to date, including currently recognized species, previously synonymized species, undescribed taxa, as well as poorly studied populations, this study produced a resolved phylogenetic framework that provided plausible species delimitation and an evolutionary time framework for the genus Ictalurus in North America.
Conclusions
Our phylogenetic hypothesis revealed that Ictalurus comprises at least 13 evolutionary units, partially corroborating the current classification and identifying populations that emerge as putative undescribed taxa. The divergence times of the species indicate that diversification of Ictalurus dates back to the early Oligocene, confirming its status as one of the oldest genera within the family Ictaluridae.

Abstract
Background
Minimally invasive modifications of inguinal lymphadenectomy (IL), including laparoscopic IL (LIL) and robotic-assisted IL (RAIL), have been utilized for penile cancer. Comparative study is necessary to guide the decision about which minimally invasive technique to select for IL. Therefore we compared RAIL with LIL performed via an antegrade approach in terms of perioperative outcomes.
Methods
We conducted a retrospective study of 43 patients who underwent RAIL (n = 20) or LIL (n = 23) for penile cancer from 2016 to 2020. The key surgical procedures and techniques are described. Complications were graded by the Clavien-Dindo classification, and operative time, estimated blood loss (EBL), lymph nodal yield, nodal positivity, postoperative drain duration, and disease recurrence during follow-up were assessed. Categorical variables were compared using chi-squared whereas continuous variables were compared by t-tests.
Results
The operative time for RAIL was significantly shorter than that of LIL (median 83 vs 95 min). Significantly less blood loss was reported with RAIL than with LIL (median 10 vs 35 ml). Lymph node yield, pathological positive nodes, the hospital stay, postoperative drain duration, postoperative complications and recurrence were similar for RAIL and LIL.
Conclusions
For patients with penile cancer, perioperative outcomes of RAIL and LIL were similar, but there was less blood loss, a shorter operative time for robotic cases.
Allee effects in an invasive social wasp: an experimental study in colonies of Vespula germanica
Authors: Melo Romina , Masciocchi Maité , Corley Juan C. 
Published: July 2022

Abstract
1. Allee effects are based on the existence of mutually beneficial intraspecific interactions which make individual fitness and per capita growth rate increase along with the increase in the number of individuals in a population or group. Allee effects are often noted when individuals fall below a given number and the success of a group or population drops. 2. In eusocial insects, cooperation is an evident defining feature, since conspecifics are essential to successfully perform different tasks, such as foraging and breeding. Such interactions suggest that social insects are susceptible to Allee effects. 3. We studied Allee effects in the eusocial yellowjacket wasp Vespula germanica. We experimentally explored component Allee effects and the underlying mechanism through the removal of workers in experimental colonies. In nests with different removal percentages, we quantify the number of gynes produced, the body mass of gynes and the amount of protein-food collected by foragers. 4. We found that the worker removal was associated with a reduction in the number of gynes produced and affected food gathering. Also, colonies in which worker removal was higher than 44.4% did not produce any gynes. We suggest that a possible mechanism that could be producing the component Allee effect is cooperative food collecting. 5. Our results highlight the importance of the worker caste in the success of eusocial species. We also provide for the first time, evidence of Allee effects at nest level of V. germanica, which can have practical significance for the management on this invasive wasp.

Abstract
2,4-dinitrotoluene (2, 4-DNT) is a common environmental pollutant. The toxic effect on mammalian of 2,4-DNT has been well studied, but its toxicity on aquatic organisms is little known. In this study, zebrafish (Danio rerio) were exposed to 0, 2, 4, 8, 12 and 16 mg/L 2,4-DNT to first determine 96 h semi-lethal concentrations (LC50), and then exposed to 0, 2, 4 and 8 mg/L for 5 d, determine liver toxicity of 2,4-DNT. Exposed zebrafish developed hypoxia features, such as floating head and breathing rapidly, and then died. 96h LC50 of 2,4-DNT in zebrafish was 9.36 mg/L. Histological data revealed that 2,4-DNT severely damaged the liver tissues, following with the round nucleus, dense interstitial tissue, dense arranged hepatocyte cords and more inflammatory cells. Additionally, the results of qPCR result indicated that the lower levels of lipid transport and metabolism (apoα2, mtp, ppar-α and acox) were noticed. But, exposed to 2,4-DNT for 5 d significantly upregulated the expression levels of genes involved in respiration (hif1a, tfa and ho1.). These results indicated that 2,4-DNT exposure disturbed lipid transport and metabolism and oxygen supply in zebrafish, which could contribute to severe damage in liver and death.

Published: July 2022

Abstract
Phytoremediation using woody plants can effectively reduce heavy metals (HMs) concentrations in soils. However, the remediation capacity of woody plants depends on soil and environmental conditions. To evaluate the HMs remediation potential of woody plants from different mining areas, we analyzed the HMs accumulation characteristics of roots, shoots and leaves of 12 dominant native woody plants in iron and lead-zinc mining areas. The distribution of HMs in plants varied with the type of HMs pollution in the two mining area. Available phosphorus (AP) and available potassium (AK) in soil were potential factors for the uptake of HMs by woody plants. In areas heavily contaminated with Pb, Cd and As, abilities of woody plants to accumulate Pb, Cd and Zn from soil were suppressed by AP, and the abilities to accumulate Pb, Zn, Cr and Ni from soil were suppressed by AK. Cyclobalanopsis glauca and Rhododendron simsii had strong enrichment and translocation abilities for Cd and Mn, Pinus elliottii for Cd, Liquidambar formosana for Mn and Paulownia fortunei for Zn. Castanopsis sclerophylla, Rhus chinensis, Rhododendron simsii, Liquidambar formosana, Photinia × fraseri,and Paulownia fortunei could grow under ultra-high concentration of As. The plants listed above can be used as potential species for phytoremediation in iron and lead-zinc mining areas.
Income Inequality and Economic Complexity in Africa: Interaction Effect of Governance Quality
Authors: Beyene Amsalu Bedemo 
Published: July 2022

Abstract
This study examines the effect of economic complexity on income inequality through the interaction role of governance factors. The study used data obtained from 24 African countries from 2000 to 2018. The systems GMM method of estimation was employed to predict the effect of variables of interest on income inequality. The findings show that economic complexity has a positive significant effect on income inequality. However, the coefficient of the interaction term is negative and significant implying that while economic complexity increases income inequality, that increase in inequality was significantly offset by the governance factor. The estimated results for disaggregated governance factors suggest similar findings except for political stability. Unlike other dimensions of governance, political stability further deteriorates the effect of economic complexity on income inequality. The overall result entails important policy implications in that for economic complexity to have a weaker deteriorating effect on income inequality, it should be accompanied by an improvement in the governance factors.

Abstract
Background: Esophagectomy offers the chance of cure for esophageal cancer, however, the optimal circumferential extent of surgery remains uncertain. Yet, the practice of en bloc esophagectomy (EBE) and meso-esophagectomy (TME) reached inconsistent results, which led to the proposal of this study was to evaluate the surgical and oncological effect of EBE and TME on the esophageal cancer patients.Methods: Five databases were searched through March 1st, 2022, and the references of eligible studies were further searched in the databases and assessed. Randomized controlled trials (RCTs) comparing the efficacy of EBE or TME were included. The outcomes were recorded in the forms of mean difference (MD), risk ratio (RR), odds ratio (OR) and hazard ratio (HR) with its corresponding 95% confidence intervals (CI). Results: Overall, a total of 14 RCTs involving 3106 subjects were included. Compared with standard resection, a higher blood loss (MD=56.29, (14.80, 97.77), P=0.008), more lymph nodes acquired (MD=14.39, (9.79, 19.00), P<0.001) and better long-term outcomes for early (OS: HR=0.31, (0.10, 0.96), p =0.04; DFS: HR=0.71, (0.41, 1.21), P=0.21) and advanced staged esophageal cancer patients (OS: HR=0.47, (0.33, 0.66), p <0.001; DFS: HR=0.62, (0.38, 0.99), P=0.05) were observed in the EBE surgery group, while TME showed less blood loss (MD=-74.03, (-96.69, -51.38), p <0.001), shorter operation time (MD=-32.37, (-65.12, 0.37), p =0.05) and better overall survival (HR=0.74, (0.55, 0.98), p =0.04).Conclusion: EBE is highly technically demanding and associated with comparable surgical trauma and better long-term outcomes. And TME is accompanied with better long-term prognosis without improving operative bleeding and operation time. Further prospective studies are required to verify the efficacy of EBE and TME.

Published: July 2022

Abstract
Wildfire is a hazardous natural phenomenon that leads to significant human fatalities, catastrophic environmental damages, and economic losses. Over the past few years, the intensity and frequency of fires have increased worldwide. Studies have been conducted to develop distinctive solutions to minimize forest fires. Systems for distant fire detection and monitoring have been established, showing improvements in data collection and fire characterization. However, wildfires cover vast areas, making other proposed ground systems unsuited for optimal coverage. Unmanned aerial vehicles (UAVs) have become the subject of active research in recent years. Deep learning-based image processing methods demonstrate improved performance in various tasks, including detection and segmentation, which can be utilized to develop modern forest firefighting techniques. In this study, we established a novel two-pathway encoder-decoder-based model to detect and accurately segment wildfires and smoke from the images captured using UAVs in real time. Our proposed nested decoder uses pre-activated residual blocks and an attention-gating mechanism, thereby improving segmentation accuracy. Moreover, to facilitate robust and generalized training, we prepared a new dataset comprising actual incidences of forest fires and smokes, varying from small to large areas. In terms of practicality, the experimental results reveal that our method significantly outperforms existing detection and segmentation methods despite being lightweight. In addition, the proposed model is reliable and robust for detecting and segmenting drone camera images from different viewpoints in the presence of wildfire and smoke.
Citizen scientist efforts in tracking the distribution of the Cuban treefrog (Osteopilus septentrionalis)
Authors: Goldberg Nisse , Sharples Alexis D. 
Published: July 2022

Abstract
To understand the distribution of the invasive Cuban treefrog (CTF, Osteopilus septentrionalis) along eastern Florida, USA, observational records from the Early Detection and Distribution Mapping System (EDDMapS) app were compared for numbers of observations, relative abundances per observation, estimated sizes, and habitat descriptions among eastern Florida counties from 1996-2021. EDDMapS is a reporting tool for invasive species that citizen scientists can upload observations that are then confirmed by experts. The mean annual number of observations per county from 2013-2021 was more than five times greater than those from 1996-2012. CTFs were primarily associated with yards and residential buildings. Mean lengths were 2.3-3.9 cm with greatest lengths of 7.0 and 8.0 cm recorded in 2019 and 2020. County mean latitude was not correlated with number of records or CTF lengths. Southern counties and northern Duval County had the greatest public engagement. The contributions and documentation of citizen scientists’ observations in coordination with regional experts can be used to inform local management efforts designed to control CTF populations, an invasive parasite-spreading species that negatively impacts local diversity.

Published: July 2022

Abstract
Objective: The ribosomal protein, uS19, is known to be associated with cancers but the molecular mechanisms underlying its involvement in oncogenesis is not fully understood. Herein, we report the findings from an in silico approach to predict the collaborative partners of uS19 in oncogenic pathways. Results: Using the bioinformatics tools of VAST (to identify candidate partners), ClusPro and PatchDock/FireDock (to simulate protein-protein interaction/docking), our analysis revealed 9 computationally-supported interacting partners of uS19 that have relevance to cancer pathways. These proteins are TMEM237, SLC22A23, SLC13A4, SLC7A1, CUBN, CBLIF, RRP1B, LMP2, and EBNA1. Our findings suggest that the role of uS19 in neoplastic malignancies may involve multiple pathways via interaction with various proteins.

Published: July 2022

Abstract
A component of urban landscape, smell sources affect the urban atmosphere based on various activities. In this atmosphere, several unpleasant odors and pleasant smells are present and dispersion of these smells vary based on spatial attributes. Thus, in the present study, urban smellscapes in Kastamonu province urban center with various smellscapes and diverse physical structure were determined with human evaluator and smell measurement device to determine whether urban physical structure and climatic factors were effective on the dispersion modeled with the IDW method in GIS. Since the odor density changes depending on temperature and humidity, the study was carried out in all seasons for 1 year and serial measurements were analyzed for 1 month in August in the most suitable climatic period. The study findings demonstrated that smell sources and intensity varied based on spatial and climatic properties on a route with different occupancy types; thus, smell did not affect the space at different point but as an area. Therefore, the element of smell should be integrated into planning and design work based on the dispersion property of smell.
Self-management strategies for chronic low back pain: a systematic narrative review
Authors: Zhou Tianyu , Salman David , McGregor Alison 
Published: July 2022

Abstract
Background: Chronic low back pain (CLBP) is a highly prevalent musculoskeletal condition affecting nearly 60-80% of the general population within their lifetime. Given the large numbers of people affected, self-management approaches offer a potentially cost-effective approach to manage this condition. Our study sought to determine the core components of, and outcomes for, successful self-management of CLBP. Methods: This narrative review was conducted using a systematic approach to search journal articles in English that focused on CLBP self-management. MEDLINE, EMBASE, CINAHL, and PsycINFO databases were used to identify publications with terms relating to back pain and self-management from 2016 until 2022.Results: In total, 53 studies were found suitable for inclusion in the review. Core components of self-management strategies include exercise, education, and psychological interventions. The most common outcomes to assess self-management focused on functional disability, and pain intensity, followed by health-related quality of life, anxiety and depression, spine flexibility, and trunk muscle endurance.Conclusions: Inconsistencies in the content of self-management interventions and outcome measures used for assessing self-management programmes were found across the literature. A consensus on the key components of self-management interventions, and how they should be evaluated, will pave the way for research to determine if self-management can effectively manage CLBP.

Published: July 2022

Abstract
Considerable evidence points to a dominant role of inflammation in the tumor pathology. The biological response of the immune system can be triggered by Toxoplasma gondii as a common brain-tropic parasite. The aim of this study was to investigate an association between Toxoplasma infection and brain tumors. This case-control study was performed on sera of brain tumor patients (n=124) and age- and sex-matched control subjects (n=124) in Southern Iran. Data related to tumor site and type were collected during sample collection. Anti-Toxoplasma IgG was assessed by enzyme-linked immunosorbent assay (ELISA). Seroprevalence anti-Toxoplasma IgG was significantly higher in brain tumor patients 30.6% (38/124) compared with 12.1% (15/124) of the healthy controls (OR 3.211; 95% CI 1.658 to 6.219; p=0.001). The highest seroprevalence was detected in pa­tients with ependymoma (100%), followed by glioblastoma (83%), pituitary adenoma (47.3%), astrocytoma (27.2%), schwannoma (23%), and meningioma (22.6%). The parasite infection was correlated to brain tumor’s location i.e., the patients with frontal lobe and sella region tumors had higher seropositivity compared with others (P<0.05). The higher prevalence of Toxoplasma infection among patients with brain tumor compared with the control group indicates a probable association between the infection and brain tumors.
The Effects and Client Experiences of Online and Face-to-Face Dialectical Behaviour Therapy for Emotion Dysregulation: A Mixed Methods Study
Authors: Whitchurch Mabel , Humayun Sajid , Robinson Oliver C. 
Published: July 2022

Abstract
Background: This research examines whether the effectiveness of Dialectical Behavioural Therapy (DBT) differs between online and face-to-face therapeutic modalities, and explores the experience of participation in these modalities. Methods: In Study 1, we compared DBT’s effectiveness between modalities by analysing pre-collected client self-report measures from a London-based charity (N = 59) across two non-randomised groups; online clients and face-to-face clients seen between 2018 and 2021. In Study 2, we conducted semi-structured interviews with a subsample of Study 1 participants (N = 10) with the primary aim of capturing the client experience of each modality, and the secondary aim of capturing the general client experience of DBT. Results: It was hypothesised that emotion dysregulation would reduce following DBT regardless of modality, which results supported. It was also hypothesised that DBT would be less effective online, but no difference was identified. A model of the general client experience was proposed, consisting of five themes: ‘the process of learning’, ‘from feeling alone to a sense of community’, ‘physical factors’, ‘improvements in my life’, and ‘DBT beyond the course’. Differences in experience between modalities were identified, and each contributed to the effectiveness of the therapy in distinct ways. Conclusions: Emotion dysregulation reduces following face-to-face and online DBT. The implications are that practitioners may wish to continue to deliver online DBT beyond the Covid-19 pandemic, thereby reducing costs and increasing accessibility. Trial Registry: The trial has been retrospectively registered with the Open Science Framework (www.osf.io).

Published: July 2022

Abstract
The oxygen pump is a complex component of liquid rocket engine, and is also one of the main vibration sources of engine. In this paper, the unsteady fluid exciting load was studied considered the coupling of gap flow and main flow. The results were verified through test of liquid rocket engine. Modal characteristics of oxygen pump case-volute with different liquid medium filled was tested. The Rayleigh damping parameter was derived by considering the frequency characteristics of fluid excited. Thus, a complete transient dynamic model was established. The transient dynamic response of oxygen pump case-volute under unsteady fluid excited was studied. At the same time, the time-domain and frequency-domain characteristics of vibration response were revealed. The analysis method was verified by comparing with the statistical distribution of test results. The vibration response of oxygen pump case-volute mainly shows frequency doubling of rotational speed, among which the 12X and 18X frequencies are prominent.
