Abstract

Increasing apparent nutrient digestibility is critical for improving beef cattle growth performance and increasing ranch profitability. Therefore, we investigated the effects of the dynamic assembly process of Allium mongolicum Regel powder (AMRP) on the fecal microbiome of Angus calves as well as the apparent nutrient digestibility, and growth performance. Twenty-four Angus calves were divided into four groups (n = 6) and treated with 0 (ZAMR), 10 (LAMR), 15 (MAMR), or 20 (HAMR) g/d/calf AMRP for 122 days. Growth performance parameters were recorded, and fecal samples were collected on days 1, 90, and 122. The results showed that the addition of AMRP did not affect Firmicutes or Bacteroidota, which are core microbes in the fecal microbiome. There was a decrease in the alpha diversity of the fecal microbes on day 122 compared to that on days 1 and 90, with 23 differential microbes screened. Correlation analysis revealed that a variety of differential microbes were significantly associated with apparent nutrient digestibility and growth performance. The apparent digestibility of dry matter and crude protein were significantly greater in the LAMR group (P < 0.050). In conclusion, AMRP at a dose of 10 g/d/calf was more favourable for increasing apparent nutrient digestibility, and improving growth performance.

Abstract

This study focuses on the synthesis of a novel Cerium-Magnesium (CeO2-MgO) binary oxide nanomaterials by a simple co-precipitation process, which was then used to remove harmful pollutants such as Cr(VI), Cu(II), and F. The morphology, phase, crystallite size, thermal stability, functional groups, surface area, and porosity of the synthesized nanomaterial were determined using XRD, SEM, FTIR, TGA/DTA, and BET studies. The prepared nanomaterials showed adsorption selectivity of Cu(II) ≈ F-> Cr(VI) with a high adsorption capacity of 84.3−133.3 mg/g for Cu(II), Cr(VI), and F-. The distribution coefficient (Kd) for F- and Cu(II) was found to be in the range of 104 mL/g which was good enough. The adsorption isotherms for Cr(VI), Cu(II), and F- followed the Freundlich isotherm model and the pseudo-second-order kinetic model in linear and nonlinear forms, indicated multilayer adsorption. Maximum removal of Cr(VI), Cu(II), and F- ions was found to be 92.84%, 98.88 %, and 95 %, respectively, for a high initial concentration of 50 mg/l by 2 g/l dosages of prepared CeO2-MgO binary oxide nanomaterials employed as an adsorbent in this study. The results showed that novel CeO2-MgO binary oxide nanomaterials are promising adsorbent for removing hazardous inorganic contaminants from the water due to their adsorption capability and chemical stability.

Authors: Rao Qian , Li Huiqiang , Yang Ping , Guo Ziou 
Published: June 2024

Abstract

Mo2C@Fe3O4 and three kinds of MO2-doped Mo2C@Fe3O4 were successfully fabricated as novel particles for the degradation of MIT and HEDP in a 3D electro-Fenton (EF) system. The combination of Mo2C and Fe3O4 as heterogeneous catalyst particles showed an enhancement for the catalytic activity in the system. Furthermore, the Mo2C@CeO2@Fe3O4 particles exhibited superior activity for MIT and HEDP degradation compared to the other two particles. The MIT, COD (MIT), HEDP and COD (HEDP) degradation rates using Mo2C@CeO2@Fe3O4 particles were 97.2%, 70.6%, 73.6% and 44.7%, respectively. Based on the characterization of the synthesized particles, leaching concentration of Fe2+, generation of H2O2 and free radical, the reasons for the difference in degradation performance among the three type particles and the excellent performance of Mo2C@CeO2@Fe3O4 were comprehensively analyzed. At last, some important experimental parameters, such as particles dosage, current density and aeration intensity, which would obviously affect MIT and HEDP degradation performance were studied.

Published: June 2024

Abstract

Background
To investigate the relationship between changes in miR-377-3p and cell cyclin G2 (CCNG2) expression and clinical features of pregnant women in preeclampsia (PE) and to further analyze the effect of miR-377-3p on CCNG2.
Methods
120 pregnant subjects were recruited consisting of 70 PE and 50 healthy pregnancies. The expression of miR-377-3p and CCNG2 mRNA were detected through RT-qPCR, and the protein expression of CCNG2 was examined through Western Blot. The Pearson test was used to analyze the relationship between miR-377-3p and CCNG2 mRNA expression and clinical parameters related to pregnant women with PE, and the association between them. Dual luciferase assay to verify the effect of miR-377-3p on CCNG2.
Results
The expression of miR-377-3p in the peripheral plasma and placenta of pregnant women in the PE group was lower than that in the control group, and the expression levels of CCNG2 mRNA and protein were higher than that in the control group. Expression of miR-377-3p and CCNG2 mRNA in plasma and placenta of pregnant women with PE was correlated with systolic, diastolic blood pressure and neonatal birth weight. miR-377-3p and CCNG2 were consistently expressed in plasma and placental tissues, and their expressions were negatively correlated. Dual luciferase assay showed that miR-377-3p negatively regulated CCNG2 expression in HTR-8/SVneo cells.
Conclusion
Aberrant expression of miR-377-3p and CCNG2 in pregnant women with PE was associated with the severity of PE and its prognosis. It is hypothesized that miR-377-3p may be involved in the pathogenesis of PE through targeted inhibition of CCNG2 expression.
Experience and attitude of psychiatric nurses in caring for patients with repeated non-suicidal self-injury in China: A qualitative study
Authors: Yue Leiyu , Zhao Rui , Zhuo Yu , Kou Xiaomin , Yu Jianying 
Published: June 2024

Abstract

Background: Theincidence of non-suicidal self-injury (NSSI) is high and often occurs repeatedly. Psychiatric nurses play a vital role in the care and treatment of NSSI patients, as they have the most frequent contact with patients. The attitude of nurses has a direct affect on the quality of care they provide to patients. Negative care experiences and attitudes of patient aversion on behalf of nurses may delay the observation and treatment of changes in the patient's condition, leading to irreversible risks. Although cross-sectional studies have investigated the attitudes of medical staff toward NSSI patients, quantitative research results cannot comprehensively reflect the emotional experiences and complex psychological changes of the study subjects. A few studies have focused on the psychiatric nurses' care experiences and attitude toward patients with repeated NSSI.
Objective: This study aimedto explore psychiatric nurses' care experiences and attitudestoward patients during repeated NSSI.
Methods: A qualitative descriptive design using individual, semi-structured interviews. Using purposive sampling，18 psychiatric nurses were recruited from a mental health center in Chengdu, China. Semi-structured interviews were conducted and audio-recorded. Audio-recordings were transcribed verbatim and analyzed using thematic analysis.
Results: Four themes emerged from the analysis: psychiatric nurses’ care experience, perceptions, care attitude and coping style toward repeated NSSI patients. Psychiatric nurses have experienced negative care experiences and severe career burnout during the patient's repeated NSSI. Nurses' attitudes toward NSSI patients changed during repeated NSSI, from understanding to indifference to anger and resentment. At the same time, it was found that nurses' coping style with NSSI patients could be divided into three stages, namely, active coping, neglect and perfunctory, and criticism and punishment.
Conclusions: The findings have implications for health care systems regarding interventions to improve nurses' care experience and attitude toward repeated NSSI patients. These findings suggest that enhancing nurses' understanding of NSSI, establishing standardized emergency response and intervention programs, guiding positive professional values and responsibility, and improving nurses' caring attitudes can promote the early detection and timely intervention of NSSI.
Self-healing Polymer Gel with Cascade-Responsive Properties

Published: June 2024

Abstract

Materials that exhibit cascade-responsive self-healing similar to that of living organisms can be of great practical value. However, developing them has been challenging. Herein, we demonstrate a polymeric material that can achieve cascade-responsive self-healing via a mechanical-force-triggered self-crosslinking reaction. Ferrocene is used as a mechanophore and its decomposition when the material is subjected to a mechanical force generates Fe3+, which forms a complex with catechol residues present in side chains; thus, forming a new network structure. This cross-linking results in a self-healing efficiency of 100 % after compression at 50 MPa for 5 min and standing for 72 h at room temperature. This strategy also provides the material with self-strengthening ability under repeated mechanical loading. The material exhibited the ability to resist the diffusion of micro cracks caused by high pressure in seawater. This study provides design principles for the construction of a new generation of intelligent bio-like self-healing materials.

Abstract

Introduction.
Increasingly, research involving the culture and metagenomic analysis of swabs from mobile phones suggests that these devices are important fomites with the potential to contribute to the dissemination of microbes, acquisition of nosocomial infections, development of antimicrobial resistance, and ultimately increased healthcare costs.
Aim.
This study aimed to conduct a survey of healthcare professionals attending an international general practice conference to assess their attitudes and opinions on mobile phone hygiene.
Methods.
A survey of 544 individuals attending an international general practice conference (WONCA) was undertaken in Sydney, Australia in October of 2023.
Results.
Most respondents (98%) agreed mobile phones harbour microorganisms. Furthermore, 84% supported the introduction of a "6th moment" in hand hygiene protocols, specifically targeting the sanitization of mobile phones.
Conclusion.
The findings underscore the necessity of incorporating mobile phone sanitization into hand hygiene practices to combat the spread and evolution of antimicrobial-resistant organisms. UV-C technology emerges as a promising approach for the efficient and effective disinfection of mobile phones in healthcare settings.

Published: June 2024

Abstract

Compressibility and structural evolution of K-cymrite, hexagonal high-pressure KAlSi3O8·H2O, has been studied up to 18 GPa using synchrotron single crystal X-ray diffraction in Ne pressure medium. K-cymrite retains its original symmetry P6/mmm up to a pressure of 7.3 GPa. As the pressure increases from 7.3 to 8.5 GPa the weak satellite reflections appear on diffraction patterns and remains up to maximum applied pressure of 18 GPa indicating incommensurate modulation. However, main reflections can be still indexed in hexagonal cell and structure successfully solved in initial P6/mmm group. After pressure release, K-cymrite reverts to initial non-modulated single-crystal state. The parameters of third-order Birch-Murnaghan equation of state for K-cymrite are V0 = 190.45(12) Å³, K0 = 56.5(7) GPa and K’ = 3.2(12), with bulk modulus notably deviating from earlier result (45(2) GPa) obtained in NaCl media.
Which One Breaks Down, Chapman-Enskog Expansion or Darcy-Brinkman Body Force Lattice Boltzmann Scheme?
Authors: Zhu Jiujiang 
Published: June 2024

Abstract

In this paper, we demonstrate that the claim of "Breakdown of Chapman-Enskog expansion" reported in reference paper1 was made by misunderstanding some concepts in literature. We will prove that the Chapman-Enskog expansion on Darcy-Brinkman body force lattice Boltzmann scheme for porous media only recovers pure fluid viscosity as classical BGK2 Lattice Boltzmann model does3, rather than the effective viscosity of porous media. We will show Darcy-Brinkman's body force lattice Boltzmann scheme results in an artificial effective-viscosity, which has nothing to do with the real effective viscosity of porous media. Therefore, its Breakdown is due to its failure as a proper model to simulate fluid flow in porous media. We will demonstrate that gray lattice Boltzmann model4 we developed recently is a best candidate to replace Darcy-Brinkman body force lattice Boltzmann scheme. A comprehensive comparison between two models will be carried out. The numerical simulation results of two models are compared with analytic solution. And the numerical simulation consists with theoretical analysis very well.

Published: June 2024

Abstract

Background
Participation by all actors involved in health planning is a prerequisite for person-centred care and healthy ageing. Understanding the multiple knowledge needs and the values that shape oral health assessments in home settings is important both to enable participation in oral health planning and to contribute to healthy ageing.
Objective
The aim of this study was to investigate decisional needs during oral health assessments in ordinary home settings from the perspectives of older adults, home health care nurses and dental hygienists.
Methods
Data was collected in ordinary home settings through 24 team-based oral assessments and 39 brief, semi-structured interviews including older adults (n = 24), home health care nurses (n = 8) and dental hygienists (n = 7). Data was analysed using content analysis with a deductive approach. The analysis was guided by the Ottawa Decision Support Guide.
Results
The analysis revealed that all participants considered participation in decision-making important but until now, older adults might not have participated in making decisions regarding oral health issues. The older adults considered participation important because the decisions had a strong impact on their lives, affecting their health. The professionals considered decision-making important for knowing what step to take next and to be able to follow up and evaluate previous goals and treatments. Organizational and personal barriers for shared decision-making among home health care nurses and dental hygienists were identified. Of the 24 older adults, 20 had different oral health conditions that objectively indicated the need for treatment. An initial important decision concerned whether the older adult wanted to make an appointment for dental care, and if so, how. Another decisional conflict concerned whether and how assisted oral care should be carried out.
Conclusion
It is important for key participants in ordinary home settings to participate in interprofessional teams in home health care. To further anchor this in theory, conceptual models for professionals from different care organizations (municipal care, dental care) need to be developed that also involve older adults as participants. Future research could bridge theory and practice by including theories of learning while exploring interorganizational oral health planning in home settings.

Authors: Kou Yu , Shui Menglin , Tang Huizi , Gu Feng , Zhu Rentao , Wang Yunshuai , Han Baowei 
Published: June 2024

Abstract

Objective
Cancer stem cells (CSC) can recruit tumor-associated macrophages (TAMs) into the tumor microenvironment and accelerate their polarization into tumor-accelerating macrophages. And TAMs maintain CSC stemness and construct niches that are poor for CSC patients survival.Thus we study that different phenotypes of TAMs and biomarkers of cancer stem cells (CSC) were measured as prognostic and predictive biomarkers in colorectal cancer (CRC).
Materials and Methods
Expression of CD86, CD163, CD44 and CD133 were detected by immunohistochemistry (IHC). Pearson chi-square test was used to analyze the correlation between CD86, CD163, CD44, CD133 and clinicopathological parameters. Survival difference and prognosis factors were established by Kaplan-Meier method with the log-rank test. Then the factors with p < 0.05 in univariate analysis were analyzed for overall survival by Cox proportional hazard regression model.
Results
The results showed that high expression of CD86 and low expression of CD163 as well as CD44 and CD133 were remarkably associated with longer survival. Then,the protein level of CD86 exhibited a negative correlation with the levels of CD133 and CD44, while CD163 showed a positive associated with CD133 and CD44. Furthermore, the high expression of CD163 and CD133 in combination were positively correlated with poor prognosis in patients with CRC.
Conclusion
These results suggested that different phenotypes of TAMs and biomarkers of CSCs can be used as potential biomarkers for the development and progression of CRC.

Authors: Mascheri Glenda , Chieffo Nicola , Lourenço P.B. 
Published: June 2024

Abstract

Seismic events have shown to be exceedingly damaging to structures over time, with serious social and economic consequences. As a result, large-scale seismic risk assessments are essential for reducing the potential damage from future earthquakes. Therefore, the proposed study attempts to examine the vulnerability and risk of unreinforced masonry buildings (URM) placed in aggregate conditions in a historical area of the city centre of Lisbon. To this purpose, a comprehensive exposure model was developed combining satellite remote sensing, GIS software, and census data. Subsequently, seismic hazard was evaluated in the area, considering both Peak Ground Acceleration (PGA) and macro-seismic intensity for different return periods (i.e. 2-50-100-475-975-2500-5000 years). Vulnerability was assessed by introducing a novel approach to earthquake risk assessment using Multi-Criteria Decision-Making methodologies. Specifically, the method employs the Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) computational methods to evaluate parameter weights and vulnerability index. Damage scenarios, fragility curves and mean damage ratios curves were provided to offer an overview of the vulnerability of the assets exposed to risk. Finally, the expected consequences were evaluated in terms of direct economic losses showing an economic loss of 595 M€ for a 475-years return period, while 1108 M€ for 5000-years. This study significantly enhances seismic risk analysis for urban areas by introducing a Multi-Criteria Approach. This method simplifies vulnerability assessment, ensuring ease of application and reproducibility. Its insights offer valuable support for disaster risk management decisions, facilitating the implementation of resilience and risk-reduction strategies.
KCS 2 TM: A key sharing approach and Deep Learning Model for Primary User Emulsion Attack detection in Cognitive Radio Networks
Authors: Biradar Shilpa , Singh Kishan , Patil Giriraj 
Published: June 2024

Abstract

The demand for wireless transmission and existence of the cognitive radio networks (CRN) insist the need for detecting the Primary User Emulsion Attack (PUEA) that authenticates the network as the licensed user for accessing the spectrum in CRN. Such condition creates disruptions in the communications. Hence, in this research, PUEA detection in the CRN is proposed using the deep learning and key sharing approach (KCS2TM model). The key sharing approach enables sharing the secret key between Primary User (PU) and Secondary User (SU) that supports the generation of the communication data, which easily assists in detecting the PUEA for which the ChimSp optimizer enabled Bidirectional Long Short Term Memory (CS2TM) model is proposed. The ChimSp optimizer is designed theoretically and mathematically to train the classifier and ensure the improved detection performances. The model provides increased accuracy, highly reliable, reduce computational cost and time are the supremacy of the model. The performance of the model is analyzed with the existing methods, which shows better accuracy sensitivity and specificity of 85.01%, 87.61% and 82.42% compared to other state of art methods.

Published: June 2024

Abstract

Background
Mental health challenges have become a pressing public health concern in recent years, with the World Health Organisation reporting a notable prevalence of such difficulties in Africa. In the region, the contributing factors to this conundrum include inadequate infrastructure, severe underfunding, and a strong adherence to masculine culture. However, there is a lack of studies exploring the effects of masculine culture on the mental health of males, particularly black African males.
Objective
The current study aimed to examine the effects of masculine culture on the mental health of Northern Sotho male youth.
Methods
The study adopted a qualitative research approach, an interpretive research paradigm, and an exploratory research design. A purposive sampling technique was used to select the sample. Researchers collected data through individual face-to-face semi-structured interviews and analysed it through qualitative content analysis.
Results
The findings suggest that Northern Sotho male youth value adhering to masculine culture, but such adherence can have negative consequences, as failing to meet these expectations may lead to mental health issues. Future studies should include black male youth from other ethnic groups to gain a more comprehensive understanding of the influence of masculine culture on mental health.
Conclusion
The current study enhanced our understanding of the impact of masculine culture on the mental well-being of Northern Sotho male youth, emphasising the importance of tailoring mental health interventions to this specific group within the study's context.
