Abstract

Context
Gestational diabetes mellitus (GDM) is a common pregnancy complication, particularly in women undergoing assisted reproductive technology (ART). An association of GDM with vitamin D in women conceiving naturally has been described; however, studies have yielded heterogeneous results.

Objective
To analyze the association between prepregnancy total and free vitamin D and GDM incidence in women undergoing ART.

Methods
Post hoc analysis of a prospective study at the Reproductive and Genetic Hospital of CITIC-Xiangya in Changsha, China. Total and free vitamin D were measured 1 day before embryo transfer. The patients were screened for GDM using the oral glucose tolerance test.

Results
A total of 1593 women were included in the study, among whom 256 (16.1%) developed GDM. According to international guidelines for total 25-hydroxyvitamin D [25(OH)D], 47 (2.9%) patients had sufficient (≥30 ng/mL) levels, while 696 (43.7%) were insufficient (20 to &lt;30 ng/mL) and 850 (54.4%) were deficient (&lt;20 ng/mL). Comparing GDM and non-GDM patients, there was no significant difference in total nor free vitamin D levels (P = .340 and .849). Similarly, analysis of GDM rates by quintiles of total and free 25(OH)D showed no significant association in one-way ANOVA (P = .831 and .799). Multivariate logistic regression, considering age, BMI, and fasting glucose, also did not show a significant influence of the 2 vitamin D forms on GDM incidence (P = .266 and .123 respectively).

Conclusion
In this relatively vitamin D deficient/insufficient ART cohort, the degree of neither total nor free vitamin D deficiency before pregnancy was associated with the occurrence of GDM.

Designing a learning environment based on the spiral of skills to overcome the didactic obstacles associated with teaching the Daniell cell
Authors: Mennani Mourad , Raouf Khadija , Khyati Abderrahim 
Published: November 2023

AbstractIn a teaching context based on the competency approach, the creation of an appropriate teaching-learning environment requires, among other things, teachers to master the meaning of the concepts taught and teaching-learning activities designed according to the constructivist approach and the investigative approach. In this article, we focused on the operating principle of the Daniell cell. The research study involved identifying the epistemological gaps of 58 future teachers in relation to the concepts describing the previous theme via an open questionnaire, as well as the degree of compliance of the activities proposed in the textbook with the curricular guidelines. The main results showed that the respondents had not mastered the meaning of the positive and negative poles of a cell or the concept of its electrical voltage. With regard to the textbook studied, we found that the design of the activities did not comply with the principles of the competency-based approach and the spiral progression of knowledge. To overcome these constraints, we propose pedagogical designs aimed at reinforcing and developing the skills of teachers and learners while progressing in the spiral of knowledge.
Visualization of the membrane surface and cytoskeleton of oligodendrocyte progenitor cell growth cones using a combination of scanning ion conductance and four times expansion microscopy

Published: November 2023

Abstract
Growth cones of oligodendrocyte progenitor cells (OPCs) are challenging to investigate with conventional light microscopy due to their small size. Especially substructures such as filopodia, lamellipodia and their underlying cytoskeleton are difficult to resolve with diffraction limited microscopy. Light microscopy techniques, which surpass the diffraction limit such as stimulated emission depletion microscopy, often require expensive setups and specially trained personnel rendering them inaccessible to smaller research groups. Lately, the invention of expansion microscopy (ExM) has enabled super-resolution imaging with any light microscope without the need for additional equipment. Apart from the necessary resolution, investigating OPC growth cones comes with another challenge: Imaging the topography of membranes, especially label- and contact-free, is only possible with very few microscopy techniques one of them being scanning ion conductance microscopy (SICM). We here present a new imaging workflow combining SICM and ExM, which enables the visualization of OPC growth cone nanostructures. We correlated SICM recordings and ExM images of OPC growth cones captured with a conventional widefield microscope. This enabled the visualization of the growth cones’ membrane topography as well as their underlying actin and tubulin cytoskeleton.
The Homeland Kaleidoscope: Perceptions of Threats and Coping Among Israeli Civilians in a Diversity of Conflict Zones

Published: November 2023

Abstract
This paper explores perceptions of threat and the subjective ability to cope with belligerency in conflict zones using the diversity of Israel’s security arenas. Three research populations were defined, all adult residents in Jewish or mixed localities with a high probability of involvement in a security conflict or in which confrontations occurred between 2002 and 2014: residents of the northern border area (n = 385), residents of the Gaza area (n = 262), and residents of Judea and Samaria (n = 496). Stratified sampling was conducted in each population to generate representative samples. The fourth research population served as the control group for this study: a representative random sample of all Israeli residents aged 18 and over living in Jewish localities (n = 493). The main insight that arises from this study is that residents’ attitudes and understanding of the security situation, their perceptions of threat, and their ability to cope with threat are not exclusively shaped by concrete security incidents. Instead, their attitudes and perceptions are the product of multiple formative factors acting concurrently. In each region and population group, it is possible to identify a “cumulative context” that crystallizes from four key factors that shape residents’ perceptions: (a) the socio-economic background of the population and the community, (b) factors related to community organization, (c) geographic proximity to the source of threat, and (d) experience and memories of past events.
Optical skipping rope induced transverse OAM for particle orbital motion parallel to the optical axis

Published: November 2023

Abstract
In structured light tweezers, it is a challenging technical issue to realize the complete circular motion of the trapped particles parallel to the optical axis. Herein, we propose and generate a novel optical skipping rope via combining beam shaping technology, Fourier shift theorem, and beam grafting technology. This optical skipping rope can induce the transverse orbital angular momentum (OAM) (i.e., nominal OAM, whose direction is perpendicular to the optical axis) and transfer it to the particles, so that the particles have a transverse torque, thereby causing the particles to rotate parallel to the optical axis. Experimentally, our optical tweezers validate that the designed optical skipping rope realizes the orbital motion of polystyrene particles parallel to the optical axis. Additionally, the experiments also demonstrate that the optical skipping ropes manipulate particles to move along the oblique coil trajectory and three-dimensional (3D) cycloidal trajectory. Using the laser beam induced OAM, this innovative technology increases the degree of freedom for manipulating particles, which is of great significance for the application of optical tweezers in optical manipulation, micromechanics, and mimicry of celestial orbits.

Published: November 2023

Abstract
Spinal cord injury (SCI) is a serious disabling injury, and the main factors causing SCI in patients include car accidents, falls from heights, as well as heavy blows and falls. These factors can all cause spinal cord compression or even complete rupture. After SCI, problems with the movement, balance, and walking ability of the lower limbs are most common, and SCI can cause abnormalities in patient’s movement, sensation, and other aspects. Therefore, in the treatment of SCI, it is necessary to strengthen the rehabilitation training (RT) of patients based on data science to improve their motor ability and play a positive role in the recovery of their walking ability. This article used lower limb rehabilitation robot (LLRR) to improve the walking ability of SCI patients and applied them to SCI rehabilitation. The purpose is to improve the limb movement function of patients by imitating and assisting their limb movements, thereby achieving pain relief and muscle strength enhancement and promoting rehabilitation. The experimental results showed that the functional ambulation category (FAC) scale scores of Group A and Group B were 0.79 and 0.81, respectively, in the first 10 weeks of the experiment. After 10 weeks of the experiment, the FAC scores of Group A and Group B were 2.42 and 4.36, respectively. After the experiment, the FAC score of Group B was much higher than that of Group A, indicating that Group B was more effective in improving patients’ walking ability compared to Group A. This also indicated that LLRR rehabilitation training can enhance the walking ability of SCI patients.
Quantifying Variation in Unconventional Gas Production Using the Continuous Wavelet Transformation
Authors: McPherson Matthew , Kuznetsov Dan 
Published: November 2023

Abstract
Within the Queensland energy industry, unconventional gas, such as Coal Seam Gas (CSG) production holds significant importance. This study employs the Continuous Wavelet Transform (CWT) to analyze variations in CSG production, aiming to comprehend its complex production dynamics. The primary objectives of this research are to identify and categorize gas rate production variations, quantify their attributes—such as frequencies, durations, and magnitudes—and explore their integration into forecasting models.
The study's results demonstrate successful identification and categorization of significant variations, specifically categorizing two types of variations impulse and step events. Through the CWT, the attributes of these events are quantified. Moreover, the obtained attributes are used to refine production forecasting via applying recreated production variations to conventionally smooth forecasting models such as type curves or history matching.
The broader impact of the study lies in its ability to provide deeper insights into CSG reservoir behavior. By uncovering patterns often obscured by traditional analysis methods, the CWT approach allows for better understanding of the operational dynamics. Quantifying the production variation into meaningful metrics results in more accurate and reliable production forecasts and more informed decision-making in optimizing production strategies.

Abstract
The first ever CO2 foam fracturing new technology in Kuwait Oil Company (KOC) history was executed flawlessly in late 2021. Three treatments were executed. Co2 Foam Fracturing proved its significant added value of improving productivity in deep depleted tight carbonate Jurassic reservoirs, enhance flow back, reduce water consumption and carbon emission, and enable early production plus improving operation efficiency and cost saving. The stimulation operation has proven to be a huge success for all multidisciplinary teams involved as preliminary results showed over 50-70% production increase compared to offset wells.
The main challenges of acid fracturing stimulation in depleted reservoirs are the need for extended formation cleanup to flow back the injected fluids via prolonging Nitrogen lift that add higher operational costs and intervention operations. Therefore, energetic high foam efficiency frac fluid becomes essential to assist flowback and retrieve pumped frac fluids from reservoir. To tackle these challenges, Carbon Dioxide CO2 is pumped in liquid phase as energetic fluid together with normal frac fluids. Due to CO2 liquid nature, high foam efficiency can be reached (40 – 50%) at much lower friction losses. So, it enables achieving pumping frac at high rates and high foam efficiency. The main benefits of CO2 Foam frac are better fracture cleanup due to expansion of the stored compressed gas in the liquid CO2, fluid loss control that is provided by foam, minimized fracture conductivity damage, and the increase in hydrostatic pressure while pumping that translates to lower surface pressures during injection.
The selected pilot well is in depleted deep tight carbonate reservoir area of North Kuwait Jurassic gas fields. The executed acid fracturing operation required close planning starting from Q1-2021. Many challenges faced from logistical issues, lack of infrastructure and CO2 resources for the multi-faceted operation due to COVID-19 pandemic limitations. These challenges were tackled ahead with the integration of technical and operations teams to bridge the knowledge gap and to enable executing the operation safely.
The pilot well’s net incremental production gain is estimated at 50-70% compared to offset wells, with improved flowback and formation cleanup with less well intervention. The resulting time and cost savings as well as the incremental well productivity and better operation efficiency confirmed high perspectives for the implemented foam acid fracturing approach. Another two CO2 Foam acid fracturing wells were executed with good results too.
This paper will demonstrate the value of CO2 foam fracturing in depleted reservoir and KOC experience post first application and its plans to expand CO2 Foam Fracturing application across KOC different fields.
Investigating Causal Associations Among Gut Microbiota, Metabolites, and Irritable Bowel Syndrome: A Mendelian Randomization Study
Authors: Zhou Chen , Yi Ying , Taishi Yezi , Wang Lei , Qu Jie 
Published: November 2023

Abstract

Background
Growing numbers of evidence indicates that changes in the gut microbiota and its metabolites are associated with irritable bowel syndrome (IBS). But their causality has not been clarified.
Methods
We performed a two-sample Mendelian randomization (MR) study using genome-wide association study (GWAS) summary statistics to estimate the effects of gut microbiota and its metabolites on IBS. FinnGen GWAS (4605 IBS cases and 182423 controls) and UKB GWAS (1121 cases and 360073 controls) were utilized. The discovery set came from the FinnGen consortium while the replication set came from the UK Biobank. Wald ratio (WR), inverse variance weighted (IVW), MR-Egger, and weighted median (WM) were the methods to analyze causality, and MR results are verified by several sensitivity analyses.
Results
Combining the results of the discovery set and the replication set, we demonstrated a potential causal relationship between Class Actinobacteria (PIVW:9.31E-06, OR:0.632, CI:0.516–0.774), Genus Bifidobacterium (PIVW:3.01E-06, OR:0.667, CI:0.563–0.790), and deoxycholate (PWR: 0.043, OR: 3.412, CI: 1.041–11.180) and IBS. We found that Class Actinobacteria and Genus Bifidobacterium reduced the risk of IBS while deoxycholate increased its risk. In reverse MR analysis, the IVW results revealed no causal relationship between IBS and gut microbiota and its metabolites which were positive results screened in the discovery set. Further analysis of heterogeneity (P > 0.05) and pleiotropy (P > 0.05) confirmed the robustness of MR results.
Conclusions
We proved a potential causal relationship between the gut microbiota and its metabolites and IBS, providing new biomarkers for gut health and IBS treatment targets, However, further research is needed to determine their exact relationships.
Proteomic Analysis of Collagen: A Mass Spectrometry Approach to Material Identification of Shadow Puppet Cultural Relics

Published: November 2023

Abstract
Shadow puppets are a popular art form in various regions, including China, Indonesia, and Turkey, and are rich in cultural significance. However, there is a considerable lack of research on the materials, diseases and conservation techniques related to shadow puppet relics. Material identification is the basis for understanding the production process of ancient shadow puppet relics and evaluating their deterioration degree. The microscopic morphology and infrared spectroscopy results in our experiments showed that the traditional methods of ancient skin identification were not effective in the shadow puppet samples. In order to achieve accurate identification, we used biomass spectrometry in proteomics to examine two puppet relics and commercially available modern shadow puppets. The results showed that the above samples could be detected by mass spectrometry with abundant peptides, including peptides specific for bovine skin. These peptides cannot be found in other commonly used materials for making shadow puppets, including the skins of pig, sheep, deer and horse. It is worth mentioning that we have found the peptides specific to yellow cowhide in two ancient shadow puppet relics samples. Therefore, the proteomic evidence shows that the raw materials of the two shadow puppet relics samples are yellow cowhide. Four modern samples also confirmed the reliability of material identification using proteomics. The proteomic evidence shows that the biological mass spectrometry will contribute to the scientific research of shadow puppet relics and other skin and leather cultural relics.
