Wellbore Stability Enhancement of Water Based Drilling Mud Using Polyvinyl Alcohol
Authors: Poungui Danielle , Sugai Yuichi , Sasaki Kyuro
Published: May 2023

Wellbore instability is a major preoccupation during drilling operations and is highly dependent of the physiochemical features of the drilling mud. The hydrophilic clays are used in making drilling mud as they provide extensive viscosity and gel strength, and other rheological properties important for optimum drilling mud performance. However, the segregation of the suspended particles of the once optimum mud to create mud cake against the wellbore formation leads to phases imbalance in the mud system, degrading the physiochemical characteristics of the now worn-out mud after several cycling in and out of the well. Although it is crucial to consider the influence of bottomhole conditions in mud rheological alteration, it is necessary to highlight the direct correlation of most mud physiochemical features with the swelling index of the mud. Therefore, optimization of drilling mud is still up to date mostly about swelling control of the mud thus solid-liquid balancing. Overtime, research papers addressing drilling mud enhancement transitioned from mechanical means such as Loss Circulation Materials (LCM) to chemical additives including polymers which as economically profitable and have swelling abilities. Polyvinyl alcohol one most desirable polymers for future drilling fluid designing as it has proved to influence mud rheology and cake filtration positively. Therefore, this study is an attempt to assess the impact of polyvinyl alcohol on wellbore isolation of a water-based drilling mud. The experiment included two types of Polyvinyl Alcohol (PVOH): Non-ionic PVOH and Cationic PVOH. Each PVOH was added to a set of 3 samples at concentrations 0.1, 0.3, and 0.5 wt.%. An additional sample with no polymer was used as a reference sample. The samples were each subjected to 5h of static pressurized filtration at atmospheric temperature. After which Spectral analysis where performed, and Permeability estimated using Darcy's Law. The results show significant influence on Polyvinyl Alcohol on mud phases distribution. Major dehydration of samples was observed as the sample without PVOH recorded the highest filtrate production while the samples with Cationic, Non-Ionic, and Conventional PVOH had average reduction of 21%,38%, and 43% respectively. The mud cake permeability of samples drastically drops at the least concentration of PVOH with a noticeable difference in permeability despite having the same PVOH concentrations. Those differences are attributed to PVOH-specific structural compositions. This study provides evidence of Polyvinyl Alcohol being responsible for improving mud thermal stability while helping any industry applying drilling activities to expand the range of polymer types that can be used to attain the desired drilling mud for a particular formation.
Effects of pore water pressure on the slope profile of a laboratory simulated rainfall-induced landslides
Authors: Menon Varun , Kolathayar Sreevalsa
Published: May 2023

This paper presents a methodology to identify the controlling parameters of rainfall-induced landslides. Two laboratory scale model of a typical slope has been created with the help of a tilting flume setup incorporated with rainfall simulators to understand the landslide fluidization process using various sensors and cameras. The results obtained with this study will help determine the most efficient monitoring parameters to be considered for developing a landslide early warning system (LEWS). The tilting flume setup was created with 45-degree and 60-degree slopes. The pore water pressure parameters were measured, and instantaneous photographs were taken continuously after simulating artificial rainfall using rainfall simulators. The landslide mechanics that cause the initiation of soil movement have been closely monitored. The summary of this study will help develop an early warning system for landslide-prone regions. The findings of this study emphasize that pore water pressure monitoring is not the best method to develop an early warning system as the pressure values are unpredictable in a massive heterogeneous soil body and sloping angle. However, there is a sudden release of pore pressure right after the failure of the mass, which is evident from the results obtained.

Background Hemodynamic parameters derived from pulse wave analysis have been shown to predict long-term outcomes in patients with heart failure (HF). Here we aimed to develop a deep-learning based algorithm that incorporates pressure waveforms for the identification and risk stratification of patients with HF. Methods The first study, with a case-control study design to address data imbalance issue, included 431 subjects with HF exhibiting typical symptoms and a left ventricular ejection fraction (LVEF) less than 45% and 1545 control participants with no history of HF (non-HF). Carotid pressure waveforms were obtained from all the participants using applanation tonometry. The HF score, representing the probability of HF, was derived from a one-dimensional deep neural network (DNN) model trained with characteristics of the normalized carotid pressure waveform. In the second study of HF patients, we constructed a Cox regression model with 83 candidate clinical variables along with the HF score to predict the risk of all-cause mortality with rehospitalization. Results To identify subjects using the HF score, the sensitivity, specificity, accuracy, F1 score, and area under receiver operating characteristic curve were 0.867, 0.851, 0.874, 0.878, and 0.93, respectively, from the 10-fold cross-validation of the DNN, which was better than other machine learning models, including logistic regression, support vector machine, and random forest. With a median follow-up of 5.8 years, the multivariable Cox model using the HF score and other clinical variables outperformed the other HF risk prediction models with concordance index of 0.71, in which only the HF score and five clinical variables were independent significant predictors (p < 0.05), including age, history of percutaneous coronary intervention, concentration of sodium in the emergency room,N-terminal pro-brain natriuretic peptide, and hemoglobin. Conclusions Our study demonstrated the diagnostic and prognostic utility of arterial waveforms in subjects with HF using a DNN model. Pulse wave contains valuable information that can benefit the clinical care of patients with HF.

Early prediction and timely intervention are particularly essential for high-risk preterm infants. Brain magnetic resonance imaging (bMRI) is frequently used alongside functional evaluations to improve predictions of developmental outcomes. This study aimed to assess voxel-based brain volumetry in extremely preterm infants using bMRI at term equivalent age (TEA) and investigate its association with developmental outcomes. From March 2016 to December 2019, high-risk preterm infants (birth weight < 1500g or gestational age < 32 weeks) with bMRI at TEA and follow-up developmental data assessed by Bayley-III were included. For bMRI volumetry, manual tracing and segmentation were performed on T1-weighted scans, and after smoothing, voxels were calculated for each brain segment. Forty-seven subjects were enrolled and categorized into typical/delayed motor groups. Results revealed a significant difference in ventricle size and ventricle ratio in bMRI at TEA between the groups. Even after controlling for other factors that could influence developmental outcomes, ventricle ratio emerged as a robust, single predictor for future motor development. This study suggests the potential clinical utility of bMRI volumetry in predicting motor development outcomes.

Published: May 2023

Large volume soft tissue defects greatly impact patient quality of life and function while suitable repair options remain a challenge in reconstructive surgery. Engineered flaps could represent a clinically translatable option that may circumvent issues related to donor site morbidity and tissue availability. Herein, we describe the regeneration of vascularized porcine flaps, specifically of the omentum and tensor fascia lata (TFL) flaps, using a tissue engineering perfusion-decellularization and recellularization approach. Flaps were decellularized using a low concentration sodium dodecyl sulfate (SDS) detergent perfusion to generate an acellular scaffold with retained extracellular matrix (ECM) components while removing underlying cellular and nuclear contents. A perfusion-recellularization strategy allowed for seeding of acellular flaps with a co-culture of human umbilical vein endothelial cell (HUVEC) and mesenchymal stromal cells (MSC) onto the decellularized omentum and TFL flaps. Our recellularization technique demonstrated evidence of intravascular cell attachment, as well as markers of endothelial and mesenchymal phenotype. Altogether, our findings support the potential of using a bioengineered porcine flaps as a novel, clinically-translatable strategy for future application in reconstructive surgery.
Cost-Effective Electrodeposited Mixed Transition Metal Electrocatalysts for Efficient Hydrogen Evolution Reaction
Authors: Golrokhifar Saeedeh , Shahroudi Ali , Habibzadeh Sajjad
Published: May 2023

Hydrogen is a clean fuel with high energy density, considered one of the alternative energy sources of the future. Hydrogen evolution reaction (HER) could produce pure hydrogen on a large scale while striving for effective electrocatalysts. Here, binary and ternary mixed transition metals (Mn, Co, and Ni) were synthesized by an electrodeposition method and employed as efficient HER electrocatalysts. It was found that the combination of transition metals could positively tune the corresponding morphology and activity rather than using single metals. Namely, NiMn electrocatalysts with an onset potential of 83 mV and a Tafel slope of 103 mV.dec− 1 showed superior activity toward HER in alkaline media compared to the other developed electrocatalysts. This high activity was related to improved intrinsic activity, higher energy efficiency, and enhanced conductivity thanks to the synergy between manganese and nickel.

Background The aim of this study was to evaluate the condylar morphological changes after orthodontic treatment in adult patients with Class II malocclusion using a Cone-beam computed tomography (CBCT).METHODS Images of twenty-eight adult patients with Class II malocclusion who have no temporomandibular symptoms were involved in this study. To analyze the post-treatment changes in condylar morphology, mimics 17.0 software was used to measure several values and reconstruct the three-dimensional condyle, including height of the condyle, area and bone mineral density of the maximum axial and sagittal section, volume and bone mineral density of the three-dimensional condyle and condylar head before and after orthodontic treatment. Using SPSS 19.0 software package Paired t-test was applied for comparison of condylar morphology analysis between pre-treatment and post-treatment.Results Height of condylar head increase significant (P < .05). Bone mineral density showed a decrease in the maximum axial and sagittal section, three-dimensional condyle and condylar head (P < .01). Evaluation of volume revealed that volume of both condyle and condylar head decrease considerably (P < .05). No significant difference was detected in other values ((P > .05).CONCLUSION Condylar volume decreased and height of condylar head have changed, so we speculated that adaptive bone remodeling of the condyle occurs.

Background: Hypertrophic cardiomyopathy (HCM) is a cardiovascular disease caused by genetic mutations. HCM with normal epicardial coronary arteries often reveal microvascular rarefaction and myocardial ischemia.Cluster of differentiation 36 (CD36) is a multifunctional pattern recognition membrane receptor that is highly expressed on microvascular endothelial cells (MVEC) and plays an essential role in endothelial cell function. However,whether CD36 affects vascular endothelial cell proliferation in HCM is unclear.We detected the effects of CD36 on endothelial cell proliferation and it’s underlying mechanisms in HCM.
Methods: We detected the effects of CD36 on endothelial cell proliferation and it’s underlying mechanisms in HCM. These studies were complemented by in vivo analysis of CD36 expression in cTnTQ92 transgenic mice myocardium and in vitro analysis of transfection of CD36 gene or SiRNA-CD36 to endothelial cells isolated from cTnTQ92 transgenic mice heart.
Results: In this study, we found that the expression of CD36 was higher and the microvessel density was lower in myocardial tissue of cTnTQ92 transgenic mice than that in the myocardial tissue of wild-type control C57BL/6 mice. The expressions of CD36 and p21 in endothelial cells isolated from cTnTQ92 transgenic mice heart were higher than those in control group. The expression levels of proliferating cell nuclear antigen (PCNA) and Cyclin D1 proteins were lower than that of control group, and the proliferation of endothelial cells was lower than that of control group, but the opposite results were obtained by transfection of SiRNA-CD36 to endothelial cells. Further studies showed that down-regulation of CD36 increased the expression of p-VEGFR2 and increased proliferation of endothelial cell. EGFR specific inhibitor AG1478 reversed these effects.
Conclusions: These findings suggest down-regulation of CD36 increased the expression of p-VEGFR2 and increased proliferation of endothelial cell in hypertrophic cardiomyopathy. Down-regulation CD36 expression may be a potential therapeutic strategy for the treatment of myocardial ischemia in HCM.

venetoclax (VEN) and Azacitidine (AZA) combination have shown improved survival and excellent responses in patients with untreated Acute myeloid leukemia (AML). However, frequent dose reduction (or discontinuation) occurred due to therapy-related toxicity and may limit triplet combination tolerance. This study retrospectively analyzed the characteristics and outcomes of newly diagnosed AML patients who received 100mg VEN for 14 days combined with AZA at our institution. Overall, 36 patients were enrolled, the median age at diagnosis was 64 years; after a median follow-up of 15(range 4–29) months, median overall survival (OS) and progression-free survival (PFS) for the total cohort were 17 (4–29) months and 12 (1–28) months, and for patients achieving composite complete remission (CRc) were not reached. Overall response rate (ORR) was 69.4% and CRc rate were 66.7% for the total cohort. Subgroup analysis revealed that NPM1 mutations and FAB-M5 were associated higher response rates, while adverse ELN risk group predicted inferior response. ASXL1, NPM1 and IDH1/2 mutation was statistically significant impact the PFS duration. The most common adverse events were hematological, with grade 3 or 4 neutropenia, thrombocytopenia, and anemia reported in 36%, 25%, 44% of patients, respectively. In summary, the VEN combination regimen remains effective for newly diagnosed AML in the real world despite VEN dose reductions.

Mangrove forest ecosystems are known to sequester large quantities of carbon in biomass. This paper presents a quantification of carbon stocks in aboveground (standing trees, palm, shrub, standing dead trees, downed wood, and litter), belowground (root), and total carbon stocks, and further compared between forest types (fringe and riverine) and zones (landward, middleward, and seaward/along water) of mangrove forests along the Carigara Bay in Leyte, Philippines. The aboveground carbon stocks for the standing trees were found to be higher in riverine (297.94 ± 58.39) compared to fringe mangrove forests (188.92 ± 18.51), with an overall average of 243.43 ± 31.09 Mg ha− 1. Shrub mangroves were found to be the second most contributor to aboveground carbon stocks which was significantly higher in middleward zone (14.88 ± 6.11 Mg ha− 1), though no variation was found between mangrove forest types. Whereas, all other aboveground components were the least contributors (< 1% combined), with a total average of 0.31 ± 0.10, 0.32 ± 0.10, 1.57 ± 0.27, and 0.19 ± 0.02 Mg ha− 1 for palm (Nypa fruticans), standing dead tree, downed wood and litter, respectively. Meanwhile, no significant variations were detected for belowground (roots) carbon stock, with an average of 65.23 ± 6.84 Mg ha− 1. Total carbon stocks were higher in the riverine (380.83 ± 70.91), with an average of 317.19 ± 37.88 Mg ha− 1. Overall, the results of the study highlight the significant amount of carbon stored in the biomass of the studied mangrove forests, which indicates their potential role in climate change mitigation.

In this study, a novel hydrogel preparation method is developed to formulate a 3D printable hydrogel with low swelling ratio for bio-medical scaffold. Nanocellulose fibrils is first oxidized to synthesize dialdehyde cellulose nanocrystal (DAC). The aldehyde groups on DAC can crosslink with laponite nanoclay via an esterification reaction. The mechanism between the two materials through aldehyde and hydroxyl groups is further confirmed by FTIR results. To optimize the printability and printing quality of the prepared hydrogels, the rheological properties of the gels are carefully examined to understand the shear thinning effect and the thixotropic responses. An optimal hydrogel composition of 6 wt% Laponite and 1 wt% DAC shows the best results to accurately print 3D structures with a nozzle dispenser. The printed gel structures show high mechanical strength and low swelling effect without complicated after-treatment steps. Several examples are also demonstrated to show the structural stability, accuracy, and cell viability of the printed hydrogel structures for potential in 3D bioprinting applications.
