Published: July 2024

Abstract

Background
After malaria, schistosomiasis is the second parasitic disease that causes death in the human population. Despite progress in control of infectious disease in the world, schistosomiasis still exists as an important health problem in many developing countries. Based on the extent of health measures taken in endemic countries, disease control has been done with varying degrees of success. The disease control and eradication program in Iran, as one of the infected countries, started in 1961 and continues until now. The last case of the disease was reported in 2001 and so far no positive case has been reported in Iran. Despite this issue, the offices related to the disease control program are still looking for contamination in the snail population and humans. Considering Iran's neighborhood with Iraq and the increase in tourist and pilgrimage traffic between the two countries, the risk of disease reappearance should always be kept in mind.
Methods
In this research, 400 samples of Bulinus truncatus snails were collected from different areas of endemic areas and were examined microscopically and PCR for the presence of Schistosoma haematobium cercaria.
Results
One percent of the samples were infected with Schistosoma sp cercaria, which were not related to Schistosoma haematobium by molecular PCR test.
Conclusion
Considering Iran's proximity to Iraq, the presence of suitable intermediate hosts in the region, and traffic between the two countries, the population of snails and humans should always be investigated in terms of Schistosoma contamination.

Abstract

Ranaviruses are responsible for mass die offs of wood frog (Lithobates sylvaticus) tadpoles. What happens in between epidemics is less clear, but juvenile (metamorphosed) stages are hypothesized to move Ranaviruses among wetlands and introduce or reintroduce these viruses into wetlands, initiating new outbreaks. A key question is under what circumstances can juvenile L. sylvaticus infect susceptible conspecifics. We examined Ranavirus transmission between juvenile L. sylvaticus in two settings: First, we measured transmission from a Ranavirus-infected frog to a co-housed susceptible frog via direct contact over a range of exposure periods. Second, we measured indirect transmission to susceptible frogs from a contaminated environment after a range of waiting times (i.e., from when the infected frog was removed to when the susceptible frog was exposed to the environment). We present evidence that juvenile frogs directly transmitted Ranavirus to susceptible frogs in all exposure periods (99.2% infected), with as little as one hour of co-housing resulting in 95.8% of susceptibles infected. Indirectly, 96.8% of susceptible frogs became infected after as long as 48-hour waiting times. Neither exposure period nor wait times influenced the probability of infection, because these probabilities are already high. In our linear regression models, viral load was best predicted by exposure period and cohort for the direct contact experiment, while wait time and the paired infective frog viral load best predicted viral load for the indirect contact experiment. Collectively, our results suggest that Ranavirus transmission readily occurs between recently metamorphosed wood frogs and via terrestrial environmental exposure.

Abstract

Fluororubber (FKM) has an important application in the industrial field. However, the coloring problem of FKM has always affected the performance of its mechanical properties. Herein, a novel silicon dioxide (SiO2) colored with acid orange 7 (AO7) was prepared by sol-gel method to ameliorate the mechanical properties and coloring property of FKM. Acid orange silica sol was prepared by adding AO7 to sodium silicate solution, and then colored SiO2-AO7 was prepared by freeze drying. The effects of SiO2-AO7 modified FKM on mechanical properties, thermal conductivity and coloring were systematically studied. The results show that SiO2-AO7 has the advantage of enhancing the mechanical properties of FKM without affecting its color appearance. Relative to the unmodified FKM, the tensile strength and modulus at 300% elongation saw enhancements of 47.2% and 21.8% respectively. The SiO2-AO7 offers exceptional coloration and mechanical reinforcement, showing strong suitability for industrial application.

Abstract

This study examined sex-based differences in biomechanical function and pain experience of individuals with chronic low back pain (LBP). The significant variability in biomechanical function among patients with chronic LBP underscores the importance of developing a novel mathematical method to quantify full body movement, rather than relying on individual parameters from biomechanical analyses. This method was used to examine a patient-specific factor, biological sex, that may inform motion heterogeneity among LBP patients. The results highlighted significant biomechanical sex-based differences in patients with LBP during the sit-to-stand dynamic transition, which was largely driven by variations in trunk movement. Males showed increased biomechanical impairment compared to females, although there was no sex-based difference in total time. Further, measuring pressure pain threshold highlighted lower pain sensitivity in males compared to females. There was a weak but significant negative association between pressure pain thresholds and biomechanical function for males, while females lacked an association. Possible explanations include reduced interoceptive awareness or increased kinesiophobia in males, which may influence movement patterns. This research is an initial step in uncovering the complex relationship between patient-specific factors influencing LBP disability, laying the groundwork for further exploration, and paving the way for improving outcomes with patient-specific treatments.

Authors: Dai Chunquan , Hou Mingfa , Huang Ming , Yu Haiyang 
Published: July 2024

Abstract

The paper focuses on investigating a novel sandwich panel, which incorporates extruded polystyrene foam boards (XPS) placed between the inner and outer concrete panels. These are connected using various types of shear connectors to achieve a composite action, meeting the bending resistance requirements. To study the structural performance of the sandwich panels, three representative specimens were designed. These specimens employed different types of shear connectors, namely, steel truss connectors with inclined bars at 45°, and GFRP connectors with inclined bars at 45° and 30°, respectively. The specimens underwent full-scale testing using a step-by-step four-point loading method. The test results indicated shear-compression failure of the specimens, exhibiting consistent failure modes across all specimens, and a composite action in resisting bending moments. Based on theoretical stress-strain diagrams and considering the slip phenomenon between the concrete panel and the connectors, this paper establishes an analytical model. It can reasonably estimate the ultimate load-carrying capacity of sandwich insulation panels under shear-compression failure, which has implications for subsequent engineering applications.

Published: July 2024

Abstract

Optimizing electroosmotic efficiency through enhanced electrochemical reactions has garnered significant attention in recent research. This study pioneers the integration of magnetic field technology within electroosmosis framework to reduce interface resistance and improve efficiency, deriving its theoretical basis from comprehensive magnetoelectrochemical studies. Experiments confirm a substantial effect of magnetic fields, pinpointing the anode as the optimal location for application. Specifically, the magnetic field drastically lowers interface resistance and sustains a high current, facilitating increased electrochemical reaction rates. This improvement is theoretically linked to the Lorentz force generated by the perpendicular intersection of magnetic and electric fields, enhancing ion convection and mass transfer across the soil-electrode interface, a process often hindered by low-permeability soils. Further analysis on the drainage enhancement demonstrates the ability of the anode-arranged magnetic field to significantly increase the drainage capacity and reduce treatment time. Electrochemical parameter analysis corroborates this ability to accelerate the drainage rate by its impact on the electrochemical reactions. In terms of energy consumption, analysis was conducted from multiple perspectives such as interface energy consumption, total energy consumption, and energy utilization rate, proving that strategic placement of a magnetic field at the anode significantly optimizes energy dynamics within the electroosmosis process. Additionally, the deployment of reusable permanent magnets promotes sustainability and cost-effectiveness. These advancements collectively contribute to the potential of magnetic field-assisted electroosmosis in engineering applications. While these developments represent substantial progress, there remains room for deeper exploration. Future research is projected to delve into the intricacies of magnetic field mechanisms and the refinement of design parameters to fortify their application in engineering practices.

Abstract

Lattice light-sheet microscopy (LLSM) provides a crucial observation window into intra- and inter-cellular physiology of living specimens with high speed and low phototoxicity, however, at the diffraction-limited resolution or anisotropic super-resolution with structured illumination. Here we present the meta-learning-empowered reflective lattice light-sheet virtual structured illumination microscopy (Meta-rLLS-VSIM), which instantly upgrades LLSM to a near-isotropic super resolution of ∼120-nm laterally and ~160-nm axially, more than twofold improvement in each dimension, without any modification of the optical system or sacrifice of other imaging metrics. Moreover, to alleviate the tremendous demands on training data and time necessitated by existing deep-learning (DL) methods, we devised an adaptive online training approach by synergizing the front-end imaging system and back-end meta-learning framework, which reduced the total time for data acquisition and model training down to tens of seconds. With this method, a new model can be well-trained with tenfold less data and three orders of magnitude less time than current standard supervised learning. We demonstrate the versatile functionalities of Meta-rLLS-VSIM by imaging a variety of bioprocesses with ultrahigh spatiotemporal resolution for long duration of hundreds of multi-color volumes, characterizing the dynamic regulation of contractile ring filaments during mitosis and the growth of pollen tubes, and delineating the nanoscale distributions, dispersion, and interaction pattern of multiple organelles in embryos and eukaryotic cells.

Published: July 2024

Abstract

Purpose
An entire fascial configuration at the esophageal hiatus might not be demonstrated histologically. According to observations of human fetus histology, the aim of this study was to consider which factor is likely to make the individual variation in adults.
Methods
We observed frontal histological sections containing the esophageal hiatus from 12 midterm fetuses at 12–16 weeks (crown-rump length:CRL, 85–137 mm) and 10 near-term fetuses at 26–30 weeks (CRL, 214–250 mm).
Results
At midterm, the inferior fascia of diaphragm turned upward to join the adventitia of the esophagus, but the superior fascia was underdeveloped. At near-term, both the inferior and superior fasciae often joined the adventitia in the left side but not in the right side. Fascial development advanced in the left side of the hiatus. The pleural recess as well as the upward protruding right crus of diaphragm was likely to disturb the fascial connection especially in the superior side. The foregut-midgut junction, suggested with cytokeratin 5/6 immunostaining, was located in the hiatus.
Conclusion
The phreno-esophageal membrane, interposed between the superior and inferior fasciae of diaphragm and the adventitia of esophagus, seemed to be established first in the left side at near-term. The delayed growth in the right side might connect to individual differences in adults.

Abstract

This study examines the geospatial locations of energy stations within Port-Harcourt Aba expressway to ascertain their locations if it conforms to standard practice. It also took into cognizance the in-situ monitoring of the various air pollutants within the vicinity of the energy stations. The study location is in Obio/Akpor and Port Harcourt city Local Government Area, Rivers State. The result of the proximity analysis reveals that the energy stations do not fall within the standard of 15metres specified by DPR (Department of Petroleum Resources). The various pollutants examined are PM 10, PM 2.5, carbon monoxide (Co), Nitrogen Dioxide (No2), ground level ozone (O3), and sulphur dioxide (S02). The result reveals that their concentrations values fall within the permissible limit as specified by NESREA except (C02) which is the primary pollutant was extremely highly than the permissible limit of 400 (ppm). This can be attributed to the influx of vehicles that buys fuel from the energy stations. The concentration of (C02) poses a serious health effect on the pump attendants due to their constant inhaling of the pollutants. The study concludes that energy stations should be cited at the approved DPR standard of (15metres) and actionable measures should be put in place to aid in the reduction of CO2 within the energy stations. Finally, the study recommends that there should be strict compliance to DPR standard in the siting of energy stations.

Published: July 2024

Abstract

The vehicular digital twin network (VDTN) comprises digital twins (DTs) that enable seamless communication and data transmission. This network effectively maps the Internet of Vehicles (IoV) into cyberspace, facilitating stable and efficient data sharing for corresponding physical vehicles (PVs). However, the open channels in cyberspace pose a vulnerability to malicious attacks on the data sharing process. Additionally, there is a possibility of legitimate but dishonest DTs transmitting unreliable data. To tackle these challenges, we propose a secure and lightweight data sharing scheme for VDTN in this paper, which can align with the characteristics of DTs serving as virtual agents for PVs. First, we design a trust-based attribute-matching mechanism to filter out unqualified DTs in advance. Furthermore, we develop a batch-supporting identity authentication and key negotiation protocol based on proxy signatures to ensure the security of shared data among DTs in VDTN. Security analysis demonstrates the scheme's diverse security functionalities, while performance analysis confirms its efficiency in terms of computation and communication overhead.

Abstract

Background
The role of endogenous estrogen exposure (EEE) in shaping body composition and its implications for cardiometabolic health remain understudied despite its potential significance. This cross-sectional study aimed to investigate the association between EEE and body composition indices among postmenopausal women.
Methods
Data were obtained from the Tehran Lipid and Glucose Study (TLGS), including 960 women aged over 40 years. EEE was calculated based on reproductive events, and participants were categorized into tertiles. Anthropometric measurements and body composition were assessed using standardized protocols. Linear regression models were employed to evaluate associations, adjusting for potential confounders.
Results
It was revealed significant differences in body composition indices across EEE tertiles, with increasing EEE associated with decreased fat mass, skeletal muscle mass, and fat-free mass. Moreover, women with higher EEE exhibited lower anthropometric and body composition measurements compared to those with lower EEE, even after adjusting for confounding factors. Specifically, for each year of increasing EEE, fat mass decreased by 0.12 kg, skeletal muscle mass by 0.04 kg, fat-free mass by 0.07 kg, and fat mass ratio decreased by 0.003. Comparing tertiles, women with the highest EEE demonstrated significantly lower anthropometric and body composition measurements compared to those with the lowest EEE.
Conclusion
These findings suggest a link between EEE and favorable changes in body composition, highlighting the importance of considering reproductive history in health assessment.

Abstract

Background: Heart failure (HF) is the leading cause of death in patients with maintenance hemodialysis (MHD). Biomarkers has an important guiding role in the early diagnosis, risk stratification, and prognostic assessment of HF. Increasing studies have indicated that long non-coding RNAs (lncRNAs) have played an indispensable role in the regulatory network of HF. This study was aiming to explore the expression profiles of lncRNAs in patients treated with MHD developing heart failure.
Methods: Peripheral blood mononuclear cells were isolated from 4 hemodialysis patients with reduced ejection fraction (HFrEF) and 4 hemodialysis patients with preserved ejection fraction (HFpEF), respectively. The expression profile analysis of lncRNAs was performed by using llumina Novaseq 6000 sequencer. Quantitative real time polymerase chain reaction (qRT-PCR) was used to verify the expression of representative differentially expressed lncRNAs. Based on lncRNA-miRNA-mRNA-KEGG network analysis, the potential role of candidate lncRNAs and their association with the severity of HF were further evaluated.
Results: In total, 1,429 differentially expressed lncRNAs were found between patients with HFrEF and patients with HFpEF, of which 613 were up-regulated and 816 were down-regulated (P<0.05). Five candidate lncRNAs were screened out by a series of bioinformatic analyses. After being compared with miRBase, ENST00000561762, one of the 5 candidates, was considered the most likely lncRNA to be serving as a precursor for miRNA. Nine predicted target genes were found by further lncRNA-miRNA-mRNA-KEGG network analysis, and among which ITGB5 was enriched in the actin dynamics signaling pathway. In another cohort of hemodialysis patients, the expression of lncRNA ENST00000561762 was verified by qRT-PCR. Further analysis revealed that there was a strong correlation between left ventricular ejection fraction and ENST00000561762, proBNP, and 6-minute walk distance, respectively.
Conclusion: LncRNAs expression profile was remarkably different in hemodialysis patients with HFrEF compared to those with HFpEF. Among which, lncRNA ENST00000561762 was considered as a promising biomarker for patients with HFrEF as it was predicted to be a miRNA precursor to regulate the actin dynamics signaling pathway.
