Authors: Htwe Yin Min , Shi Peng , Zhang Dapeng , Li Zhiying , Yu Qun , Wang Yong
Published: January 2024

Efficient callus induction is vital for successful tissue culture of oil palm, yet identifying genomic loci and markers for early identification of specific individuals with high potential of callus induction is still unclear. In this study, callus induction rate at 1-, 2-, and 3-months after inoculation (C1, C2 and C3) of 198 oil palm individuals were investigated as phenotypes, and totally 11,475,258 high quality single nucleotide polymorphisms (SNPs) were generated by resequencing as genotypes. Genome-wide association study (GWAS) was performed accordingly using these phenotypes and genotypes. Correlation analysis revealed a positive association of C1 with both C2 (R = 0.81) and C3 (R = 0.50). Therefore, only SNPs in C1 were identified to develop markers for screening individuals capable of callus induction at early stage. A total of 21 significant SNPs were observed in C1, in which six of them on chromosome 12 (Chr12) potentially linked to callus induction were further revealed by the linkage disequilibrium (LD) block analysis. Totally 13 SNP markers from these six loci were tested accordingly and only the marker C-12 at locus Chr12_12704856 effectively distinguishing the GG allele, which showed the highest probability (69%) of callus induction. Moreover, the method for rapid SNP variant detection without electrophoresis was established via qPCR analysis. Notably, individuals S30 and S46, carrying the GG allele, consistently showed high callus induction rates (> 50%) from C1 to C3. Our findings facilitated marker-assisted selection for specific individuals with high potential of callus induction, thereby providing valuable assistance for donor plants selection in oil palm tissue culture.

Published: January 2024

Background: Itaconic acid is a promising bio-based building block for the synthesis of polymers, plastics, fibers and other materials. In recent years, Ustilago cynodontis has emerged as an additional itaconate producing non-conventional yeast, mainly due to its high acid tolerance, which significantly reduces saline waste coproduction during fermentation and downstream processing. As a result, this could likely improve the economic viability of the itaconic acid production process with Ustilaginaceae.
Results: In this study, we characterized a previously engineered itaconate hyper-producing Ustilago cynodontis strain in controlled fed-batch fermentations to determine the minimal and optimal pH for itaconate production. Under optimal fermentation conditions, the hyper-producing strain can achieve the theoretical maximal itaconate yield during the production phase in a low-density fermentation at pH 3.6, but at the expense of considerable base addition. Base consumption is strongly reduced at the pH of 2.8, but at cost of production yield, titer, and rate. A techno-economic analysis based on the entire process demonstrated that savings due to an additional decrease in pH control reagents and saline waste costs cannot compensate the yield loss observed at the highly acidic pH value 2.8.
Conclusions: Overall, this work provides novel data regarding the individual strain properties and production capabilities, contributing to a better understanding of the itaconic acid production process with Ustilago cynodontis, especially from an economic perspective.

Published: January 2024

Plastic profiles, as the basic material for social and economic development, are mainly processed and moulded by plastic extruders. In the production process of plastic profiles, the temperature precision control of plastic extruder directly affects the plasticising and mixing effect of raw mate-rials. Therefore, the development of high-precision, fast response and stable plastic extruder tem-perature control system plays a key role in the development of plastic profile industry. In order to solve the shortcomings of the plastic extruder such as low temperature precision, slow response speed and poor anti-interference ability, the author has established a plastic extruder temperature control system model based on the study of PID control strategies and fuzzy PID control strategies, combined with the structural and functional characteristics of plastic extruder. Adopting a variable universe fuzzy PID control strategy to improve the performance of the plastic extruder temperature control system. The core idea of this strategy is to introduce proportional factors to change the range of the fuzzy domain. Under the condition that the fuzzy rules remain unchanged, the fuzzy domain compresses as the error decreases and expands as the error increases. Changing the domain is equivalent to adding fuzzy control rules within the same domain, thereby completing the dynamic adjustment of PID controller parameters. Through MATLAB simulation analysis and comparison, it was found that this control strategy has the advantages of short rise time, no overshoot, and strong anti-interference compared to PID control and fuzzy PID control strategies. Finally, through ex-perimental verification, it was found that this control strategy significantly changes the temperature control effect of nonlinear time-varying extruders, and has good adaptability and stability.

Published: January 2024

Background
Teff is a prominent cereal crop grown in various parts of Ethiopia, exhibiting considerable genetic diversity for the most essential above-ground morphological traits. It forms a symbiotic relationship with arbuscular mycorrhizal fungi (AMF) to adapt to resource-limited conditions in dryland areas. Currently, AMF is becoming an essential bio-inoculant in agronomic and plant breeding programs. In a greenhouse experiment using a Complete Randomized Design (CRD) with ninety selected teff genotypes, we assessed the genetic variability and level of dependency of teff on AMF based on twelve morphological traits.
Results
All traits were significantly (P < 0.05) different among the genotypes. The genotypes were divided into six distinct clusters. The maximum and minimum inter-cluster distances were observed between Clusters IV and VI (327.85) and Clusters I and IV (71.76), respectively. High genetic divergence was observed among the tested teff genotypes evaluated between AMF inoculated genotypes. Wider genetic distance (inter-cluster) between the genotypes of clusters IV and VI, III and VI, and I and VI were important to do crossing between genotypes of these three clusters. Clusters III, VI, and I were superior for multiple crossings. Teff genotypes with higher root colonization percentage (RCP) of 54.42 to 72.29% were significantly correlated with root dry matter, root length, shoot biomass yield, and grain yield compared to low RCP (25.03 to 34.32%).
Conclusion
Group genotypes having higher genetic variability when colonized with AMF showed wider dependency of teff genotypes on AMF with implications for plant breeding.
Semiclassical Behaviour of Quasiparticle Excitations in Electron Gas
Authors: Akbari-Moghanjoughi Massoud
Published: January 2024

In current research we investigate macroscopic collective quantum effects in interacting electron gas with arbitrary degree of degeneracy due to electrostatic field-density coupling. It is found that in the one dimensional excitation model deterministic quantum charge transport can take place due to the electrostatic field coupling of the interacting electron correlations with number density variations of the electron gas. A new expression for probability current is found to be valid for collective excitations in interacting electron gas. It is also revealed that the phase-space evolution of modified Wigner distribution function for linear quasiparticle excitations resembles that of the classical free particle. In other words, semiclassical linear evolution of collective excitations in interacting quantum electron gas is quite analogous to dynamics of classical system of particles in the absence of external forces, where the interparticle electrostatic forces play the analogous role of internal classical forces. It is shown that the electrostatic field of electrons when coupled to collective electron wavefunction can also lead to directly measurable macroscopic phenomena. It is remarked that the interacting system of electrons simultaneously exhibits microscopic and macroscopic effects that are linked through the dual lengthscale behavior of collective quantum electron excitations.

Published: January 2024

Zinc Oxide Nanoparticles (ZnO-NP) are inevitably released into the environment and penetrate into the aquatic environment during production, transportation, use and disposal processes. In this study, which aims to investigate the effect of ZnO mixed into the aquatic environment, Gammarus pulex, a good indicator species, was chosen as a model organism. To carry out the study, G.pulex individuals were exposed to 0 (control), 10, 20 and 40 ppm concentrations for 24 and 96 hours and elimination periods. Samples were taken at 24 and 96 hours and elimination periods and kept at -86 °C until oxidative stress and antioxidant biomarker parameter analyzes were performed. Model organisms were taken from the experimental environment after 96 hours and kept in the water provided from the living areas for 24 hours, elimination groups were created and changes in oxidative stress and antioxidant biomarker parameters were determined. Among the biomarker parameters, SOD, catalase (CAT) activities and glutathione (GSH) and Thiobarbituric acid (TBARS) levels were measured. Measurements were carried out with CAYMAN brand ELISA kits.
Considering the study data, it was determined that ZnO-NP caused fluctuations in SOD activities, but there was no change in CAT activity, compared to the control. While there were decreases in GSH levels, it was observed that there were increases in TBARS levels.

Purpose The aim of this study was to analyze the long-term clinical outcomes of intercalary allograft reconstruction for primary malignant bone tumors in lower extremities. Methods A retrospective study was conducted on 29 patients (16 males, 13females) who underwent intercalary allograft reconstruction for primary malignant bone tumors in lower extremities between September 2007 and December 2012. The average age were 23.4 ± 15.1 years (range, 9–64) and the most common pathological type was osteosarcoma (17) followed by Ewing’s sarcoma (4), adamantinoma (4), chondrosaroma in 2, angiosarcoma of bone in 1 and undifferentiated pleomorphic sarcoma in 1. The tumor locations were in the femur in 13 and the tibius in 16. All complications and allograft failures occuered were recorded in this study. The oncological outcomes included local control, metastasis, progression-free survival and overall survival. The functional outcomes were evaluated by Musculoskeletal Tumor Society Score (MSTS-93). Results 29 patients was included in this retrosepective study and there were no patients lost in the follow-up period. The mean follow-up time was 149.8 ± 42.1 months (43–194). Three patients (10.3%) deceased in the last follow-up due to distant metastasis. The average diaphyseal bone resection length was 172.7 ± 29.2 mm (range, 130 to 240mm). The average allograft survival time was 134.4 ± 53.7 months (range, 6 to 194 months). The mean union time was 16.3 (6–29) months and overall survivorship of the allograft was 82.7% (24/29) at an average 12.5 years follow-up. The average MSTS-93 score was 86% (range, 70–100%). Ninteen patients (66.5%) had at least one complication in the follow-up time. The common unoncological complications were bone non-union (8), fracture (3), infection (2) and leg length discrepancy (LLD, 2). Conclusions The intercalary allograft reconstruction is a reliable technique to resolve the massive bone defects after primary diaphyseal bone tumor resection in lower extremities with acceptable long-term function and satisfaction.

Authors: Wu Yiling , Hou Zhiguo , Zhao Xinrui , Dong Jinxiang , Xu Hong
Published: January 2024

Here, we study layered zirconium phosphate intercalated with octadecyltrimethylammonium bromide (STAB-ZrP) as a thickener by thickening five types of base oils. The layered structure and morphology of STAB-ZrP after thickening were confirmed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The thickening ability and fluidity behavior of STAB-ZrP gel were evaluated using rheological measurements. The tribological properties of STAB-ZrP gel were investigated using a reciprocating tribometer under temperatures of 25°C and − 15°C. The rheological results showed that STAB-ZrP gel had grease-like characteristics. Naphthenic and alkyl naphthalene as the base oil can lead to the higher thickening ability. Naphthenic oil maintained the most colloidal stability at 25°C and − 15°C. STAB-ZrP gel exhibited superior anti-wear and friction reduction, owing to the formation of a solid protective film on the contact interface. This research established the relationship of STAB-ZrP with base oils in terms of their performance. STAB-ZrP acts as both a thickener and a solid additive in the STAB-ZrP gel system. This study can serve a beneficial trial for future preparations of lubricating grease.

Published: January 2024

The previous works on the operating condition of the Cameroonian sugar cane factory show that, during the rainy season, fuel moisture increases and influence the steam quality and quantity production. This is because during this season, the precipitation is high and a lot of mud usually adheres to the harvested cane and consequently increases the inert ratio of bagasse as fuel. Many attempts have been made to estimate calorific value of biomass in general and bagasse in particular with basic analysis data of proximate analysis, ultimate analysis, and chemical analysis. Data and bagasse samples were collected at the Cameroonian sugar cane factory. The effects of various parameters like cane variety, age of harvesting, source, moisture content, and sucrose on the calorific value of Cameroon bagasse have been tested. From results, it was shown that the joint action of the relative humidity rate on ash influences the Net Calorific Value (NCV). The most suitable NCV model depends on the variation of the extrinsic parameters like humidity, ash, and sugar content in the Cameroonian sugar cane bagasse. Assume, model from proximate analysis could predict more the heating value of bagasse.Then, the literature selected models from proximate analysis could be used to predict the calorific value of Cameroonian sugar cane bagasse with an average absolute error of 5.0 %.

Published: January 2024

Introduction:
A series of comprehensive focus group discussions among firefighters aroused interest in discovering the physical training programme that best improves the functional strength of firefighter trainees.
Method
A series of modified nominal group technique (mNGT) sessions were conducted to identify and rank exercises for five functional strengths (i.e., pushing, pulling, lifting, carrying, and dragging). Six subject matter experts from the firefighter academy were recruited to 1) identify the skeletal muscles involved in the functional movements using a visual aid; 2) generate ideas via brainstorming for exercises; 3) rank each exercise; and 4) modify the exercises for beginner, intermediate, and advanced levels.
Results
Males dominated the expert group (66.7%) and had an average of 11.50 ± 5.20 years of experience in physical training. The mNGTs yielded three top-ranking exercises for each functional strength: 1) Pushing: the push-up, sit-up, and jumping jack; 2) pulling: the push-up, jumping jack, and sit-up; 3) lifting: the jumping jack, push-up, and jumping squat; 4) carrying: the push-up, plank, and sit-up; and 5) dragging: the jumping jack, sit-up, and jumping squat. Then each exercise was designed for the beginner, intermediate, and advanced levels by manipulating loads.
Discussion
This study demonstrated that mNGT is an effective tool for identifying the three top-ranking exercises that address firefighter recruits’ functional strength. The experts chose multi-joint exercises targeting agonist and antagonist skeletal muscle groups and mimicking movements of daily work life. The exercises provide opportunities for common skeletal muscle groupings to be targeted simultaneously to increase cardiovascular adaptations over a shorter period, corroborated by previous empirical evidence.
Conclusion
A comprehensive physical training programme is now ready to be implemented for use among firefighter recruits

Published: January 2024

Reduced sulfur compounds such as H2S are extremely toxic and highly corrosive, produced in many industrial activities. The biological desulfurization process has been established to be a technically and economically effective alternative to traditional physicochemical processes. This study aimed to investigate the operation of three parallel biotrickling filters (BTFs) in removing H2S at different pH conditions (haloalkaliphilic, neutrophilic, and acidophilic) and their associated microbial population in the biodesulfurization process. BTF columns were inoculated with enriched inoculum and experiments were performed by gradually reducing Empty Bed Retention Time (EBRT) and increasing inlet concentration (Ci). The maximum Removal Efficiency (RE) and Maximum Elimination Capacity (EC) in EBRT 60s for haloalkaline, neutral and acidic conditions were, 91% and 179.5 g S-H2S m-3 h-1, 85.7%, and 141 g S-H2S m-3 h-1, 88% and 145 g S-H2S m-3 h-1 respectively. For visualizing the attached microbial biofilms on pall rings, Scanning Electron Microscopy (SEM) was used and microbial community structure analysis by NGS showed that the most abundant phyla in haBTF, nBTF, and aBTF belong to gammaproteobacteria, betaproteobacteria, and acidithiobacillia, respectively. The alpha analysis according to the Shannon and Simpson indexes showed a lower diversity of bacteria in the aBTF reactor than that of nBTF and haBTF and beta analysis indicated a different composition of bacteria in haBTF compared to the other two filters. These results indicated that the proper performance of BTF under haloalkaliphilic (natron) conditions is the most effective way for H2S removal from air pollutants of different industries.
Finite-time Prescribed Performance Tracking Control for Unmanned Helicopter System Using Neural Network
Authors: Li Yang , Ting Yang
Published: January 2024

In this paper, a composite finite-time prescribed performance tracking control scheme is presented for an unmanned helicopter (UH) system subject to performance constraints, model uncertainties and external perturbations. A new finite-time neural network disturbance observer (FTNNDO) with adaptive laws is designed to deal with the external disturbances and model uncertainties, which not only realizes the fast convergence rate in finite time, but also eliminates the complicated differential calculation in the traditional backstepping technique. Using the continuous adaptive law, the neural network (NN) approximate errors can be effectively estimated and compensated online without chattering and gain overestimation caused by traditional methods, thus further enhancing the robustness of the system. To constrain the tracking performance of the transient process and steady-state accuracy, a novel prescribed performance function is designed to preset the tracking errors within prescribed boundaries. Based on the FTNNDO and barrier Lyapunov function (BLF), an improved finite-time tracking controller is designed to achieve fast convergence with prescribed performance. By using Lyapunov synthesis, it is strictly proved that the finite-time convergence of the closed-loop control system can be achieved and tracking errors are always within the prescribed performance bounds. In the end, simulation results for UH tracking control system are given to demonstrate the effectiveness of developed control scheme.
Multimodal image translation algorithm based on Singular Squeeze-and-Excitation Network
Authors: Tu Hangyao , Wang Zheng , Wang Shuoping , Zhao Yanwei
Published: January 2024

Image-to-image translation methods have evolved from only considering image-level information to pixel-level and instance-level information. However, with the feature-level constraint, when channel attention (SEnet) extracts content features, its scaling degree does not add effective constraints. To address this difficulty, the multimodal image translation algorithm based on Singular Squeeze-and-Excitation Network (MUNSSE) is proposed by combining deep learning methods and traditional mechanism methods. This method used the mean idea of SVD features to help SEnet ease the degree of scaling. Specifically, SEnet used SVD to extract features to improve the Excitation operation, which helps the network to obtain new channel attention weights and form the attention feature maps.Then the the image content features are completed by convolutional features maps and attention feature maps. Finally, the content features and style features extracted by the style network are combined to obtain the new style images. Through ablation experiments, we found that the SVD parameter is 128, and the image translated by the network is optimal. According to the FID image diversity index, MUNSSE is superior to the method proposed at this stage for the diversity of generated images.
Reduced gene expression of potato apoplastic invertase inhibitor gene on CRISPR/Cas9 targeting and analyzing its transformation efficiency parameters
Authors: Dangol Sarbesh Das , Çalışkan Mehmet Emin , Bakhsh Allah
Published: January 2024

Background
Pathogen infections that affect potato yield cause severe economic losses every year. Several studies point the role of apoplastic (cell wall) invertase (CWIN) enzyme in plant defense mechanisms, and that apoplastic invertase inhibitor (INVINH1) post-translationally regulates CWIN. Nevertheless, the role of INVINH1 needs to be elucidated for several effects in plant transformation parameters and its gene expression which we sought to explore using CRISPR/Cas9 technology.
Methods and Results
In this study, we sequenced the first exon of INVINH1 gene in cv. Desiree and Solanum chacoense M6. We identified in the first exon two alleles for StINVINH1 gene in cv. Desiree and one allele for ScINVINH1 gene in S. chacoense M6. We designed two single-guided RNAs (sgRNAs) to target INVINH1 gene from diploid S. chacoense M6 and tetraploid S. tuberosum cv. Desiree using CRISPR/Cas9 based technology. In our earlier study, we have already optimized transformation protocol for M6 and cv. Desiree using Agrobacterium strains, based on which Agrobacterium strain AGL1 was chosen for CRISPR/Cas9 experiment. Our experimentation showed that heat stress at 37°C could increase the mutagenesis capability, and CRISPR/Cas9 targeting affected plant transformation parameters. It was found from the knockout experiment that the indels were present in the calli, and the candidate regenerated plants showed reduced gene expression level conducted via RT-qPCR.
Conclusion
Our study demonstrated that INVINH1 targeting affected the calli induction and regeneration rates, was effective under heat stress, and reduced its gene expression level. More studies are required to comprehend the function of INVINH1 enzyme in potato stress response and defense mechanism.
Discovery of a polyvinyl alcohol-degrading strain of the ascomycete Fusarium oxysporum and optimizing of its degradation performance of PVA
Authors: Zhang Xin , Song Juyi , Liu Chang , Chen Hui
Published: January 2024

Massive accumulation of plastics into environment has caused enormous pressure on the ecosystem. Efficient and environmentally friendly plastics degradation technologies have evolved into a global ecological challenge. Microbial degradation, as an eco-friendly plastic treatment technology, is confronted with a problem of low efficiency in its current application. Hence, it is crucial to discovery plastic biodegradable microorganisms and find the optimal conditions for their action. The aim of our study is to isolate plastic-biodegrading fungi and explore optimum conditions for their action. A strain isolate of Fusarium oxysporum was obtained from a degraded plastic handle through screening, separation, and purification and designated PDBF01 (CGMCC No.40272). In a screening assay of plastic polymers, PDBF01 only exhibited the degradability to polyvinyl alcohol (PVA), with no activity toward polyvinyl chloride, polypropylene, or polylactic acid. PVA degradation efficiency of PDBF01 was significantly affected by inoculum concentration, temperature, and degradation time. PDBF01 produced significant degradation of PVA under 28°C and 25% inoculum concentration. Moreover, the highest degradation rate reached 51.26% after 21 days. PVA degradation rate of PDBF01 was further increased to 58.83% by the addition of electrolytes (K+, Mg2+, Fe2+, and Ca2+). Our results suggested PDBF01 can be used as a potential and efficient PVA-degrading strain in practical applications.
Treatment of post-thalamic hemorrhage hydrocephalus: Ventriculoperitoneal shunt or endoscopic third ventriculostomy？
Authors: Lu Wenchao , Du Andong , Zheng Xiaomin
Published: January 2024

Background
This study aimed to compare the efficacy of ventriculoperitoneal shunt (VPS) and endoscopic third ventriculostomy (ETV) in the treatment of hydrocephalus after thalamic hemorrhage to provide reasonable surgical treatment.
Methods
The clinical data of 87 patients with hydrocephalus after TH whose external ventricular drainage(EVD) cannot be removed after hematoma absorption were retrospectively analyzed. The patients were divided into the VPS and ETV groups according to the different surgical methods. The operative time, length of hospital stay, complications, and reoperation rates of the two groups were compared.
Results
There was no statistically significant difference in intraoperative bleeding and length of hospital stay between the two groups, and all patients had the EVD tube successfully removed after surgery. There were 4 (9.5%) complications in the ETV group and 3 (6.7%) complications in the VPS group, with no significant differences in postoperative complications between the two groups.During the 1-year follow up,7 patients (16.7%) in the ETV group and 3 patients (6.7%) in the VPS group required reoperation. There was a significant difference in the reoperation rates between the two groups. In the subgroup analysis of TH with fourth ventricular hemorrhage, 6 patients (14.3%) required reoperation in the ETV group, and 1 patient (2.2%) required reoperation in the VPS group; the difference between the two groups was statistically significant.
Conclusions
ETV have good efficacy in treating hydrocephalus caused by TH and TH breaking into the lateral ventricle and the third ventricle. However, if hydrocephalus is caused by TH with the fourth ventricular hematoma, VPS is a better surgical method because the recurrence rate of hydrocephalus in ETV is higher than that in VPS. Therefore, the choice of surgical method should be based on the patient’s clinical manifestations and hematoma type.

New Hyper cross-linked polymer (HCP) of Resorcinol (1, 3-dihydroxybenzol) “R-HCP” is synthesized using Friedel-Craft Reaction for the removal of cadmium metal ions from industrial wastewater. Real industrial wastewater samples are used to evaluate the adsorption capability of R-HCP. Fabricated R-HCP is characterized through Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction analysis (XRD), EDX (Energy dispersive x-ray spectroscopy) and BET (Brunauer–Emmett–Teller). The BET surface area of R-HCP is 221.5848m2g− 1.Through salt addition method, the point of zero charge (PZC) was also determined, and its value is 2.0 pH. The greatest adsorption value of 93% was obtained at pH 10 with 0.5 g of adsorbent, 9-minute contact time and favors exothermic reaction. Langmuir, Freundlich and Temkin isotherms were studied and results shows that Freundlich model is the best fit. Adsorption kinetics investigation shows that it follows pseudo first order kinetic model. Study of the effect of interfering ions including calcium, magnesium, sodium, and potassium demonstrate the decrease in adsorption capacity to little extent. R-HCP can be recycled and have regeneration capacity which is novel and distinguished feature of this adsorbent.

Authors: ji Xiaoqing , liu shuai , Sun Chunyun
Published: January 2024

Inclusive growth is an economic model aimed at reducing inequality. Currently, China is undergoing a period of rapid digital transformation. Will digital technologies affect inclusive growth? This paper utilizes panel data from 70 large and medium-sized cities in China spanning from 2011 to 2022 to examine the impact of digital technology on urban inclusive growth. The examination considers both the economic growth and social equity effects of digital technology, and further discusses the impact channels on urban inclusive growth, particularly focusing on innovation and entrepreneurship. The results indicate that digital technology can promote inclusive urban growth; in other words, the higher the level of digital technology in cities, the better the inclusive growth. From the perspective of impact channels, digital technology enhances the inclusive growth of cities through urban innovation and entrepreneurial activities. Additionally, this paper finds that the role of digital technology in inclusive growth is more pronounced in cities with low human capital compared to those with high human capital. The impact of digital technology on inclusive urban growth is distinctly evident in the eastern region, but less so in the central and western regions.

Published: January 2024

Introduction: A professional development programme requires the identification of the most important opportunities for improvement through continuous self-assessment. In addition, a programme of competency self-perception must be validated through external observation. The aims of this study are to assess the degree of students' self-perception of the level of competence acquisition, and to study whether there is a relationship between the students' self-perception of their competence and that obtained in an external. Material and methods: To record their self-perception, the students completed a survey. Additionally, to compare the degree of self-reported competence with objectively measured clinical competence, the OSCE test from the end of the 5th year was also used. To be able to compare the self-perception items and the OSCE competency areas, an equivalence between domains was agreed by the assessors. Results: Information was collected from 93 students out of the 112. The total score for the self-perceived level of competence was found to improve significantly. All the items explored showed significantly different and increasing median scores between the three measurement times. Comparing these responses from the self-perception survey between each pair of time points where the students gave their opinion on their degree of preparation for the clinical skills practised, it can be seen that from time 1 to time 2, after the students had completed their simulation scenarios, all the dimensions were scored more highly. No significant association was found between the evaluation provided by the external OSCE assessors and that self-reported by the students at the time of taking the OSCE. Conclusion: Students perceive themselves to be more competent than their OSCE scores ultimately show. It appears that students' reported self-perception does not correlate with their respective scores on the objective test, and in principle does not seem to be a predictor of their true level of competence.

Published: January 2024

Numerous countries worldwide face significant challenges in managing Heavy metal solid wastes (HMSWs) and their associated health impacts. Despite the recognized harmful nature of heavy metals, there is a scarcity of data on the specific toxicity of HMSWs. This study utilized comparative toxicogenomic analysis of nephrotoxicity-related gene sets for heavy metals, including Fe, Cu, Co, Ni, and Mn, from the Comparative Toxicogenomics Database (CTD). Moreover, this study conducted animal experiments involving five groups of Sprague Dawley rats that were orally administered substances for a duration of 4 weeks. The control group received 1.1µM acetic acid, whereas the experimental groups were treated with leachates from copper sulfide, copper concentrate, iron ore, and cobalt-nickel-manganese ore. The rats in the treated groups exhibited reduced body weight gain, significantly decreased hematological parameters, increased white blood cell count, decreased superoxide dismutase (SOD) activity in kidney tissues, elevated malondialdehyde (MDA) levels, increased blood lactate dehydrogenase (LDH) activity, increased blood urea nitrogen (BUN), increased creatinine (Cr), and an elevated BUN/Cr ratio. Additionally, the glomerular filtration rate (GFR), BUN, and urine Cr were decreased in the treated groups. Further decision tree analysis revealed that blood LDH levels > 6.82U/gprot distinguished the treatment of cobalt-nickel-manganese and copper sulfide slag from the others, indicating the importance of blood LDH as an oxidative damage marker in assessing nephrotoxicity. Toxicogenomic analysis unveiled that the process of heavy metal- induced kidney damage involves oxidative stress, inflammatory responses, and apoptotic signaling. It also uncovered different programmed cell death processes including ferroptosis and apoptosis, in kidney cells. This study sheds light on the toxic effects of exposure to HMSWs and proposes that LDH, as an oxidative damage marker, could be pivotal in the early assessment of heavy metal-induced nephrotoxicity to safeguard public health.

Purpose
To evaluate the cost-effectiveness of a multifaceted workplace intervention to prevent and manage musculoskeletal pain (MSP) in nursing staff.
Methods
The study was a 1-year cluster-randomized controlled trial. The intervention combined participatory ergonomics, health promotion, and case management. The control group received usual care. Societal and health system perspectives were used. Costs included direct health and indirect costs. The effects were MSP and quality-adjusted life years (QALY). MSP was measured using the Standardized Nordic Questionnaire at baseline and 6- and 12-month follow-up. QALY were measured using the EuroQol-5D-3L at 6- and 12-month follow-up. Incremental costs and QALY were modelled using generalized linear models. MSP was analysed through generalized logistic models. Incremental cost-effectiveness ratios (ICERs) were calculated, and cost-effectiveness planes and acceptability curves were constructed.
Results
Total mean costs were €367 and €154 for the intervention and control group, respectively. The intervention costs were €38/person. From the societal perspective, the ICER showed that overall additional €12 (€6 from a health system perspective) were required to achieve 1-extra-percentage-point reduction of MSP. ICERs were €6 from the societal and €3 from the health system perspectives for neck, shoulders and upper back pain; €10 and €4 for low back; €33 and €14 for hands; €7 and €3for legs; €21 and €9 for the knees; and €7 and €3 for feet. The ICER was dominated by usual care in the elbows and QALY.
Conclusion
Although the efficiency of this intervention cannot be fully established, these findings are encouraging to reduce MSP in the workplace.

Published: January 2024

Due to its large electric dipole moment, the Rydberg atom exhibits a strong response to weak electric fields, hence it is regarded as a highly promising atomic antenna. However, to enhance the reception sensitivity, split-ring resonators are needed normally, which will brings sensing blind spots. Thus it is not conducive to the application of full-coverage space communication. Here we propose that an atomic antenna with an asymmetric parallel-plate resonator, can not only enhance the received signal, but also eliminate sensing blind spots (pattern roundness can reach 7.8 dB while the split-ring resonator can be up to 39 dB). We analyze the influence of structural parameters on the field enhancement factor and directionality, and further discuss the limitation of the sensitivity by using thermal resistor noise theory.This work is expected to pave the way for the development of field-enhanced Rydberg atomic antennas that communicate without a blind spot.

Background
Although immunotherapy has the potential to prolong the median survival time and overall survival of patients with lung cancer, it is also a driver of immune related adverse events, which may directly affect the therapeutic effect and reduce quality of life (QOL). Attention to measure QOL in lung cancer patients undergoing immunotherapy is under-explored because of the therapy’s relative novelty. And a great deal of empirical researches has indicated the important influence of financial toxicity (FT) and self-perceived burden (SPB) on QOL. However, yet no research has ever clarified the relationship among FT, SPB, and QOL simultaneously. Hence, the purpose of this study is to understand the level of QOL of lung cancer patients undergoing immunotherapy, and attempt to clarify the potential mediating roles of SPB on the relationship between FT and QOL.
Methods
A convenience sample of 342 lung cancer patients undergoing immunotherapy was recruited from a cancer hospital from October 2022 to April 2023 in this cross-sectional study. Participants were requested to complete the structured questionnaires: sociodemographic and clinical questionnaire, Functional Assessment of Cancer Therapy–Lung (FACT-L), Self -Perceived Burden Scale (SPBS) and COmprehensive Score for financial Toxicity (COST). Data were subjected to Pearson correlation analysis and bootstrapping analysis in the structural equation modelling.
Results
The total score of FACT-L was (79.90 ± 15.84) points in 322 lung cancer patients administrated with immunotherapy. FT (β = 0.37, P < 0.01) and SPB (β = -0.27, P < 0.01) had a direct effect on QOL. In addition, SPB partly mediated the association between FT and QOL, and the standardized indirect effect was 0.19, accounting for 33.9% of the total effect.
Conclusions
The present study revealed that lung cancer patients undergoing immunotherapy experienced a lower QOL. And higher financial burden resulted in greater self-perceived burden, thus associated with inferior QOL. It is imperative for healthcare providers to routinely assessed QOL, financial toxicity or risk and self- perceived burden for lung cancer patients undergoing immunotherapy, and assist those patients in understanding the potential financial risk of each choice and help them take more active roles in their routine clinical care.
Meningioma Characteristics Influencing Overall Survival by Race and Ethnicity

Published: January 2024

Background There are known racial and ethnic disparities affecting overall survival (OS) in meningiomas. This has largely been presumed to be due to differences in socioeconomic status (SES). However, there are conflicting studies that demonstrate better survival for Hispanic compared to Black populations, two groups with similar SES. Thus, we hypothesize additional underlying factors, including tumor biology, may differ amongst race and influence OS of patients with meningioma.
Methods We queried the NCDB for patients with pathology-confirmed meningiomas from 2012-2020. Race and ethnicity were self-reported and grouped into White, Hispanic White, Black, Hispanic Black, and Asian categories. Logistic regression analyses were performed to determine tumor and patient characteristics associated with race and Cox hazards model was performed on these characteristics to determine influence on OS.
Results We included 85,244 patients in this study. Black patients have worse OS compared to White patients. Black patients were also more likely to harbor higher grade tumors and undergo subtotal resection compared to White patients. Hispanic White patients had improved overall survival (P<0.0001) with less higher-grade tumors (P=0.0051) compared to White patients. There was no difference in overall survival for Hispanic Black patients (P=0.49) despite being more likely to have higher grade tumors (P=0.0164).
Conclusions Differences in meningioma biology may contribute to the differences in OS seen in racial groups beyond SES. Black patients are a particularly vulnerable group as they tend to harbor higher-grade tumors and undergo less aggressive surgical resections. Further studies are necessary to determine possible differences in underlying biology.

The umbuzeiro, a fruit-bearing tree endemic to the Caatinga biome, stands out for its socioeconomic and environmental relevance. Although natural to Sergipe, there is a lack of information about its populations in the state. This study aimed to characterize a natural population of umbu trees in Sergipe, covering individual characteristics to the attributes of their fruits, endocarps, and seedlings. Of the 551 fruits collected from these matrices, the majority had predominantly yellow (62%) with orange (23%) peels. The endocarps, averaging 1.83 cm in length by 1.17 cm in width, significantly influenced the fresh mass of the seedlings, with larger area endocarps associated with greater mass. Endocarps stored for different periods showed no variation in germination rate and speed. These findings not only enrich the understanding of this population but also provide crucial insights for conservation and genetic improvement programs of the species in Sergipe.

Food Propaganda in the World Wars: A Review on Food Posters
Authors: ŞENEL Pınar , SEVİGEN Murat
Published: January 2024

Propaganda is an activity that is conducted to influence the attitudes or behaviors of individuals by using communication tools. Throughout history, states have used different propaganda methods to influence their public and other states. Posters are one of the mass media tools used for propaganda purposes. States made propaganda during the World Wars, and often they used posters in this activity. Although there are studies focused on propaganda activities in World Wars, posters, and the importance of food policies, no study examining food-themed propaganda posters within the scope of the food policies. The purpose of the study is to examine the food-themed propaganda posters published during the two World Wars within the scope of the food policies. 43 food-themed posters were detected published during the World Wars for propaganda. The posters were analyzed through thematic analysis. As a result, it was determined that fourteen food policy themes were used in the posters of the world wars.
