Authors: SUN XIANGJIE , YIN HAIYAN , ZHAO FENGE 
Published: February 2024

Abstract
Background
Clinical nursing practice is the keystone of nursing education. Efficient clinical nursing practices under the guidance of clinical nursing teachers can promote patient safety and healthcare quality. This study aimed to investigate the profiles of clinical nursing teachers’ role stress, determine whether sociodemographic factors and psychological capital correlate with different role stress profiles and examine the relationship between different role stress profiles and work engagement.
Methods
This cross-sectional study was conducted in China. A total of 412 clinical nursing teachers were enrolled using 406 valid questionnaires. Clinical nursing teachers’ role stress, psychological capital, work engagement, and sociodemographic characteristics were assessed using a questionnaire. A latent profile analysis was conducted to identify the different role stress profiles of clinical nursing teachers. Univariate and multivariate unordered logistic regression analyses were used to identify the factors associated with the profiles.
Results
The findings of latent profile analysis showed three profiles: low role stress-high lack of teaching resources profile (34.3%), moderate role stress profile (57.0%), and high role stress-low lack of teaching resources profile (11.7%). Multivariate unordered logistic regression showed that clinical nursing teachers with lower education levels, contract employment, regular qualification audits, and lower psychological capital scores were more likely to belong to Profiles 2 and 3 when Profile 1 was used as a reference. The analysis of variance revealed that the work engagement scores of Profile 3 were significantly lower than those of Profiles 1 and 2.
Conclusions
Clinical nursing teachers reported heterogeneous sociodemographic and psychological capital, with significant differences in the degree of role stress between the identified profiles. Targeted interventions should be provided according to the profiles of role stress to improve work engagement and teaching quality.

Abstract

The moisture content of wood influences its machinability and the resulting quality of the machined surface. This study aims to explore the impact of varied moisture content on the final quality of beech wood cut by a CO2 laser (Fagus sylvatica L.). Laser cutting was performed on beech lumbers conditioned at moisture levels of 0%, 8%, 12%, and 18%. The Laser-cut specimens were evaluated for surface roughness and waviness by using a stylus surface profilometer at three measuring locations: top, middle, and bottom. The total color difference ΔE was also assessed using a spectrophotometer at the same three locations. The most intriguing findings revealed that surface specimens with higher moisture content are lighter than those with lower moisture content. Specifically, the top areas of specimens with different moisture content exhibited lighter shades than those in the middle and bottom areas. Notably, the surface profile of the specimens remained unaffected by variations in moisture content levels.

Abstract
Background
Fibroblast activation protein (FAP) has gained attention as a promising molecular target with potential utility for cancer diagnosis and therapy. 68Ga-labeled FAP-targeting peptides have been successfully applied to positron emission tomography (PET) imaging of various tumor types. To meet the applicable demand for peptide-based FAP tracers with high patient throughput, we herein report the radiosynthesis, preclinical evaluation, and the first-in-human imaging of a novel 18F-labeled FAP-targeting peptide.
Methods
Al18F-FAP-NUR was radiolabeled with 18F using an Al18F complex on a modified GE TRACERlab FXFN synthesis platform. The 18F-labeled peptide was evaluated against 68Ga-FAP-2286, a 68Ga-labeled FAP-targeting peptide, in biochemical and cellular assays, ex vivo biodistribution studies, and in vivo micro-PET imaging. Additionally, successful first-in-human imaging of the 18F-labeled peptide was performed in two patients with breast cancer and lung cancer, respectively.
Results
Al18F-FAP-NUR was automatedly prepared within 45 min with a non-decay corrected radiochemical yield of 18.73 ± 4.25% (n = 3). Compared to 68Ga-FAP-2286, the 18F-labeled peptide demonstrated more rapid, higher levels of cellular uptake and internalization, and lower levels of cellular efflux in HT1080-FAP cells. Micro-PET imaging and biodistribution studies conducted on xenograft mice models revealed a similar distribution pattern between the two tracers. However, Al18F-FAP-NUR demonstrated significantly higher tumor-specific uptake resulting in improved Tumor-Background Ratios (TBRs). In the patients, a significant accumulation of Al18F-FAP-NUR was found in the primary tumor. High uptake of the tracer within the bladder indicated that its major route of excretion was through urine.
Conclusion
Based on the physical imaging properties and longer half-life of 18F, Al18F-FAP-NUR exhibited promising characteristics such as enhanced tumor-specific accumulation and elevated TBRs, which made it a viable candidate for further clinical investigation.
Changes in the Net Primary Production of Ecosystems across Western Europe from 2015 to 2022 in Response to Historic Drought Events
Authors: Potter Christopher , Pass Stephanie 
Published: February 2024

Abstract

Background
Ecosystem models are valuable tools to make climate-related assessments of change when ground-based measurements of water and carbon fluxes are not adequately detailed to realistically capture geographic variability. The Carnegie-Ames-Stanford Approach (CASA) is one such model based on satellite observations of monthly vegetation cover to estimate net primary production (NPP) of terrestrial ecosystems.
Results
CASA model predictions from 2015 to 2022 for Western Europe revealed several notable high and low periods in growing season NPP totals in most countries of the region. For the total land coverage of France, Greece, Italy, Portugal, and Spain, 2018 was the year with the highest terrestrial plant growth, whereas 2017 and 2019 were the years with the highest summed NPP across the UK, Germany, and Croatia. For most of Western Europe, 2022 was the year predicted with the lowest summed plant growth. Annual precipitation in most countries of Western Europe gradually declined from a high average rate in 2018 to a low average precipitation level in 2022.
Conclusions
The CASA model predicted decreased growing season NPP of between − 25 and − 60% across all of Spain, southern France, and northern Italy from 2021 to 2022, and much of that plant production loss was detected in the important cropland regions of these nations.
Standard Points and Lines in Map Projections
Authors: Lapaine Miljenko 
Published: February 2024

Abstract

In order to be able to read the information a map conveys, we must be familiar with the distribution and size of the inevitable distorsions. Otherwise, our knowledge will be deficient or even wrong. The paper first defines the terms standard point and standard line. The standard point is the point where the inevitable distortions caused by mapping are equal to zero. This definition can be visually interpreted as a Tissot distortion ellipse that becomes a unit circle. After that, it is natural to say that the standard line is composed of standard points. A large number of examples show that the map projection does not have to have standard points at all, but that it can have one such point, two such points or a whole line of standard points. In the latter case, it can be parallels, meridians or lines parallel to the image of the middle meridian, as is the case with the Gauss-Krüger or transverse Mercator projection.

Abstract
Background
Neonatal necrotising enterocolitis (NEC) is a common intestinal disease that threatens the lives of newborns and is characterised by is chemic necrosis of the small intestine and colon. As early diagnosis of NEC improves prognosis, identification of new or complementary biomarkers is of great importance. In this study, we have evaluated the diagnostic value of CCL3 in NEC and compare its effectiveness with other commonly used biomarkers, such as procalcitonin (PCT) and C-reactive protein (CRP).
Methods
Serum samples were collected from 64 patients with NEC and 38 jaundice neonatal controls. Before initiating therapy, blood samples for whole blood count, CRP, PCT and CCL3 were obtained from all neonates. Receiver-operating characteristic (ROC) curve and multivariate logistic regression analyses were performed.
Results
Serum CCL3 level of NEC group was significantly higher than Control group. The ROC area under the curve (AUC) was 0.8614[95%confidence interval (CI) 0.7863–0.936; p < 0.0001] for CCL3, 0.8534 (95% CI 0.7682–0.9386; p < 0.0001) for PCT, 0.675 (95% CI 0.5625–0.788; p < 0.0001) for CRP, 0.579(95% CI 0.4402–0.7188 p = 0.2460) for WBC,and 0.7384(95% CI 0.6215–0.8554 p = 0.0005) for PLT. With a cut-off value of 83.33 ng/ml, the diagnostic sensitivity and negative predictive value of CCL3 were 83.33% and 80.55%, respectively.the combined use of CCL3 and PCT could significantly improve diagnostic performance for NEC (0.903; 95% CI 0.810–0.960; p < 0.0001).
Conclusions
CCL3 may be used as a promising biomarker for the diagnosis of NEC, and the combined use of CCL3 and PCT could improve the diagnosis of NEC.

Published: February 2024

Abstract

Laminar flow phenomena may occur when pore water flows at low velocities across the interfaces of soils with different properties, thus causing flow contact resistance. To explore the impacts of interfacial flow contact resistance and rheological characteristics on the thermal consolidation process of layered saturated viscoelastic soil foundation featuring semi-permeable boundaries. This paper established a new thermal consolidation model by introducing a fractional order derivative model, Hagen-Poiseuille law and time-dependent loadings. The semi-analytical solutions for the proposed thermal consolidation model are derived through the Laplace transform and its inverse transform. The reliability and correctness of the solutions are verified with the experimental data in literatures. The influence of constitutive parameters, flow contact resistance model parameters on thermal consolidation process and the interfacial flow contact resistance on foundation settlement, is further explored. The results indicate that the impact of the constitutive parameters and permeability coefficient on the thermal consolidation of viscoelastic saturated soil is related to the flow contact resistance. The enhanced flow contact resistance effect leads to a significant increase in pore water pressure and displacement during the consolidation process.

Published: February 2024

Abstract

Background: For basic training in ultrasonography (US), medical students and residents must learn cross-sectional anatomy. However, the present educational material is not sufficient to learn the sectional anatomy for US. This study aimed to provide a criterion for reading ambiguous structures on US images of upper limb through the sectioned images of Visible Korean.
Methods: US images of the right arm of a volunteer were scanned (28 planes). For comparison with US images, the sectioned images of the right upper limb (24 bits color, 0.5 mm intervals, 0.06 mm × 0.06 mm sized pixel) were used. After the volume model was constructed from the sectioned images using MRIcroGL, new sectioned images of 28 planes corresponding to the US images of 28 planes were created by adjusting the slope of the volume model. In all images, the anatomical terms of 59 structures from the shoulder to the fingers were annotated.
Results: In the atlas, which consists of 28 sets of US images and sectioned images of various slope planes, 59 structures of the shoulder, arm, elbow, wrist, palm, and fingers were observed in detail.
Conclusions: To learn the cross-sectional anatomy for US, the sectioned images from the Visible Korean project were deemed to be the most suitable data because they contained all human gross anatomical information. Therefore, we were able to interpret the ambiguous structures on the US images using the sectioned images in this study.

Authors: Köckert Ludwig , Liu Wei , Cheng Xu 
Published: February 2024

Abstract

Post-dryout heat transfer plays an important role in the safety analysis of nuclear reactors or in the design of once through steam generators, and thus attracts great interest in the research community and technical applications. In the present study, experiments on post dryout heat transfer were conducted in a uniformly heated tube test section using Freon R-134a with the following range of parameters; pressure from 11 to 28 bar, mass flux from 300 to 2000 kg/(m2 s), heat flux from 20 to 140 kW/m2, and local thermal equilibrium vapor quality of more than 100%. Both procedures with increasing and decreasing heat flux were applied, to examine the hysteresis phenomenon. In general, excellent reproducibility of experiments is proven. The behavior of wall temperature and the effect of various parameters on post-dryout heat transfer can be well explained with mechanistic processes. In total, about 9000 data points were obtained and provide a valuable data base for future development of prediction models. Based on the test data gathered, five widely applied correlations of post-dryout heat transfer were selected and assessed. It was found that both correlations using thermal equilibrium approach have a much better prediction capability than the other three correlations based on thermal non-equilibrium conditions. Further analysis reveals that the main deficiency in the thermal non-equilibrium correlations is in the prediction of actual superheating of vapor, which requires obviously further improvement.

Authors: Sideeq Ovais , Farid Farhan , Nuhu Muhammad Abubakar 
Published: February 2024

Abstract

Background
Multiple Sclerosis (MS) is a widespread autoimmune disease that affects millions of people globally. Depression among patients with MS remains poorly understood. Self-awareness, the recognition of one's emotions and limitations, has emerged as a potential factor that influences mental health. This study assessed self-awareness and its link to depression in patients with MS, thus contributing to mental health knowledge. These findings may inform targeted interventions to achieve better outcomes.
Methods
This cross-sectional study assessed the self-awareness of patients with MS. This study included 97 patients referred to the MS Research Center at Sina Hospital, Tehran, Iran. Self-awareness was evaluated using the Self-Consciousness Scale Revised (SCSR). Depression was measured using the Beck Depression Inventory-II (BDI-II). SCSR and BDI-II scores were calculated separately for each category. Participants completed an online questionnaire.
Results
The mean age of participants was 38.66 years. Family history was positive in 18.6% of the participants. The mean BDI-II was 18.40 ± 12.321. The mean for private self-consciousness was 10.28 ± 2.775, for public self-consciousness, and social anxiety was 13.32 ± 3.572, and 13.32 ± 3.405, respectively. Significant association was observed between self-awareness and BDI-II (p < 0.05).
Conclusions
Patients with Multiple Sclerosis have low private self-consciousness; high on public self-consciousness whereas average score was noted for social anxiety. There is a statistically significant link between specific sub-categories of self-awareness and severity of depression in MS patients. Concealed prognostic factors might be linked to self-awareness in individuals living with MS. Therefore, additional adamant and vibrant studies are highly endorsed.

Published: February 2024

Abstract

In this work, we present the development of light filters using a gelatin-based nanocomposite. Owing to the plasmonic properties of metallic nanoparticles (NPs), these filters can be customized across the UV-Visible-NIR spectrum. Additionally, the filters are designed for modular use, allowing for the addition or removal of desired spectral ranges. The nanocomposites are composed of biodegradable and biocompatible materials. These plasmonic gelatin-based filters block light due to the Localized Surface Plasmon Resonance (LSPR) of the NPs and can be tailored to meet various requirements, akin to a diner selecting options from a menu. This approach is inspired by culinary techniques, and we anticipate it will stimulate further exploration of biomaterials for applications in optics, materials science, electronics, and more.

Abstract
Background
Neoadjuvant chemoradiotherapy (NCRT) followed by surgery is a standard treatment for locally advanced esophageal squamous cell carcinomas (ESCCs). However, evolution of genome and immunogenome in ESCCs driven by NCRT remain incompletely elucidated.
Methods
We performed whole-exome sequencing of 51 ESCC tumors collected before and after NCRT, 36 of which were subjected to transcriptome sequencing.
Results
Clonal analysis identified clonal extinction in 13 ESCC patients wherein all pre-NCRT clones disappeared after NCRT, and clonal persistence in 9 patients wherein clones endured following NCRT. Clone-persistent patients showed higher pre-NCRT genomic intratumoral heterogeneity and worse prognosis than clone-extinct ones. In contrast to clone-extinct patients, clone-persistent patients demonstrated a high proportion of subclonal neoantigens within pre-treatment specimens. Transcriptome analysis revealed increased immune infiltrations and up-regulated immune-related pathways after NCRT, especially in clone-extinct patients. The number of T cell receptor-neoantigen interactions were higher in clone-extinct patients than clone-extinct ones. Decrease in T cell repertoire evenness positively correlated to the decreased number of clonal neoantigens after NCRT, especifically in clone-extinct patients.
Conclusions
We identified two prognosis-related clonal dynamic modes driven by NCRT in ESCCs. This study extended our knowledge in the field of ESCC genome and immunogenome evolutions driven by NCRT.
