Characterization of Sand Production for Clayey-Silt Sediments Conditioned to Hydraulic Slotting and Gravel Packing: Experimental Observations, Theoretical Formulations, and Modeling
Authors: Jin Yurong , Wu Nengyou , Li Yanlong , Yang Daoyong 
Published: May 2022

Summary
In our previous work (Jin et al. 2021), an experimental effort has been made to microscopically observe sand failure, migration within a matrix, invasion toward gravel-packing zones, and production conditioned to the openhole gravel packing, while three sanding patterns (i.e., fractures, wormholes, and fluidized channels) have been identified. The first pattern is associated with an uneven strain-stress effect, while the last two patterns result from liquid seepage. To theoretically reproduce our previous experimental measurements, in this study, the experimental techniques have been further modified and improved to eliminate the associated uneven strain-stress effect by uniformly injecting water into a radial flow vessel. Experimentally, by generating slots near the gravel packing, sand failure dynamics, sand flow paths, and sand production for the clayey-silt sediments can be microscopically observed, geometrically depicted, and volumetrically quantified conditioned to different operational conditions (i.e., no hydraulic slot, single hydraulic slot without proppants, single hydraulic slot with different lengths, and double hydraulic slots with different intersection angles). Theoretically, a wormhole growth model has been proposed to reproduce the sand production for both hydrate-free and hydrate-bearing sandpacks by accounting for a sand failure criterion as well as the porosity and permeability alteration models. Good agreements between the measured and simulated data (i.e., pressure and temperature profiles, cumulative gas and water production, and produced sediment volumes) have been achieved. The experimental results show that hydraulic slotting can be used to not only effectively mitigate the skin effect near a wellbore but also decrease the pressure gradient near the wellbore. In this way, the possibility of sand failure is decreased if a predesigned hydraulic slotting after well completion is deployed. It is revealed that the operational conditions dictate the sand failure patterns, sand production volumes, and sizes of the produced particles. Similar to hydrate dissociation, sand production is also divided into three stages: before dissociation (transport of free particles or weakly consolidated particles), during hydrate dissociation (sand detachment because of the loss of hydrate cohesion and massive water production), and after hydrate dissociation (transport of fully unlocked particles). Furthermore, sensitivity analysis shows that cumulative sediment production and permeability increment are affected by the following strong-to-weak order: intrinsic failure resistance, tortuosity, Kozeny coefficient, and absolute permeability. Also, the breakdown pressure is dominated by absolute permeability, while pressure during the stable stage is mainly dictated by the intrinsic failure resistance, tortuosity, and Kozeny coefficient.
Research on sliding mode controller of high-speed maglev train under aerodynamic load
Authors: Liu Meng-juan , Wu Han , Zeng Xiao-Hui , Yin Bo , Hao Zhan-zhou 
Published: May 2022

Abstract
Maglev train is suspended through the surrounding track, which overcomes manydisadvantages caused by the direct contact between the wheel and rail oftraditional vehicles, such as excessive friction. It has the advantages of high speed,comfortable riding, less maintenance, strong climbing ability, and so on. However,when the train is running at high speed, it will be subjected to a strong unsteadyaerodynamic load. The violent disturbance of aerodynamic load will inevitablylead to the corresponding feedback of electromagnetic force and the change ofthe suspension gap, which will affect the stability and safety of the train.

Published: May 2022

Abstract
Background and Objective: Dairy products may be associated to an increased risk of asthma, although there is little scientific evidence to back this up. The goal of this study was to exploring the association between dairy consumption and asthma symptoms.Materials and Methods: This cross-sectional study was conducted on children and adolescents aged 6-8 and 13-14 living in central Iran. Dietary food consumption was assessed using a multiple-choice questionnaire. Logistic regression was used to obtain odds ratios for the association between milk, other dairy products, and total dairy consumption with risk of asthma symptoms.Results: In total, 7667 participants (3414 boys and 4253 girls) were included in the current study. Milk intake and total dairy consumption were not associated with the likelihood of wheezing, asthma confirmed by a doctor, current asthma, and asthma medication use. also, there was no association between other dairy products intake and odds of wheezing in the past 12 months in the crude model. But, after adjustment for several confounders those in the top category had lower odds of wheezing in the past 12 months than those in the bottom category (OR: 0.58; 95% CI: 0.40-0.85).Conclusion: In conclusion, the consumption of dairy products other than milk, including cheese and yogurt, might reduce the likelihood of wheezing in children and adolescents.

Abstract
PurposePurple acid phosphatases (PAPs) have included the largest classes of non-specific plant acid phosphatases. Most characterized PAPs were found to play physiological functions in phosphorus metabolism. In this study, we investigated the function of AtPAP17 gene encoding an important purple acid phosphatase in A. thaliana.MethodsThe full-length cDNA sequence of AtPAP17 gene under the control of CaMV-35S promoter was transferred to the A. thaliana WT plant. The generated homozygote AtPAP17-overexpressed plants were compared by types of analyses with corresponding homozygote atpap17-mutant plant and WT in both of + P (1.2 mM) and –P (0 mM) conditions.ResultsThe highest and the lowest amount of Pi observed in AtPAP17-overexpressed plants with 111% more and atpap17-mutant plant by 38% less than WT in + P condition, respectively. Furthermore at the same condition, APase activity of AtPAP17-overexpressed plants increased 24% compared to the WT. Inversely, atpap17-mutant plant represented 71% decrease in compared to WT plants. The comparison of fresh weight and dry weight in the studied plants showed that the highest and the lowest amount of absorbed water belonged to OE plants (with 38 and 12 mg plant− 1) and Mu plants (with 22 and 7 mg plant− 1) in + P and –P conditions, respectively.ConclusionThe lack of AtPAP17 gene in the A. thaliana genome led to a remarkable reduction in the development of root biomass. Thus, AtPAP17 could has an important role in the root but not shoot developmental and structural programming. Consequently, this function enables them to absorb more water and eventually associated with more phosphate absorption.

Abstract

Objective: Chile is among the most successful nations worldwide in COVID-19 vaccine rollout. By December 31st, 2021, 84.1% of the population was fully vaccinated, and 56.1% received booster doses using DIFFERENT TYPES OF COVID-19 VACCINES. In this context, we aimed to estimate the anti-SARS-CoV-2 antibodies following the infection and vaccination campaign.Study design: Population-based cross-sectional serosurvey based on a representative sample of the cities of Santiago, Coquimbo/La Serena, and Talca used in a previous study.Methods: We selected the participants using a three-stage stratified sampling. They were blood-sampled on-site and answered a questionnaire regarding COVID-19-associated variables and vaccination antecedents using Wantai SARS-CoV-2 Ab ELISA to determine seroprevalence. This research followed the generic protocol of World Health Organization Unity studies.Results: We recruited 2,198 individuals aged 7-93 between October 5th and November 25th, 2021. In our sample, 2,132 individuals received COVID-19 vaccinations (97%); 67 (3.1%) received one dose; 2,065 (93.9%) received the complete scheme; and 936 received the booster jab (42.6%). Antibody seroprevalence reached 97.3%, ranging from 40.9% among those not vaccinated to 99.8% in those with booster doses (OR=674.6, 154.8-2938.5). SARS-CoV-2 antibodies were associated with vaccination, previous COVID-19 diagnosis, age group, and city of residence. In contrast, we found no significant differences in the type of vaccine used, education, nationality, or type of health insurance.Conclusion: We found a seroprevalence close to 100% in the population aged seven years and older, primarily due to the successful vaccination program, which has a strong emphasis on universal access.
Tec1 and Ste12 transcription factors play a role in adaptation to low pH stress and biofilm formation in the human opportunistic fungal pathogen Candida glabrata
Authors: Purohit Divya H , Gajjar Devarshi U 
Published: May 2022

Abstract
Eukaryotic cells respond to environmental cues through mitogen activated protein kinase (MAPK) signaling pathways. Each MAPK cascade is specific to particular stimuli and mediates specialized responses through activation of transcription factors. In the budding yeast Saccharomyces cerevisiae , the pheromone-induced mating pathway and the starvation-responsive invasive growth/filamentation pathway generate their distinct outputs through the transcription factors Ste12 and Tec1 respectively. In this study, we report the functional characterization of these transcription factors in the closely related human opportunistic pathogenic yeast Candida glabrata . Two homologues each for S. cerevisiae TEC1 and STE12 were identified in C. glabrata . Both C. glabrata Tec1 proteins contain the N-terminal TEA DNA binding domain characteristic of the TEA/ATTS transcription factor family. Similarly, the DNA-binding homeodomain shared by members of the highly conserved fungal Ste12 transcription factor family is present in N-terminus of both C. glabrata Ste12 transcription factors. We show that both C. glabrata STE12 genes are at least partial functional orthologues of S. cerevisiae STE12 as they can rescue the mating defect of haploid S. cerevisiae ste12 null mutant. Knockout of one of the STE12 genes (ORF CAGL0H02145g) leads to decreased biofilm development; a stronger biofilm-impaired phenotype results from loss of both CgSTE12 genes in the double deletion mutant ( Cgste12 ΔΔ). The transcript levels of one of the TEC1 genes (ORF CAGL0M01716g) were found to be upregulated upon exposure to low pH, its deletion causes slightly increased sensitivity to higher concentrations of acetic acid. Heat shock leads to increase in mRNA levels of one of the STE12 genes (ORF CAGL0M01254g). These findings suggest a role of Tec1 and Ste12 transcription factors in the regulation of some traits (biofilm formation, response to low pH stress and elevated temperature) that contribute to C. glabrata ’s ability to colonize various host niches and to occasionally cause disease.

Published: May 2022

Abstract
Objectives
The aim of this study was to assess the microcirculation and the expression patterns of wound-healing related cytokines around narrow-diameter implants in type 2 diabetes mellitus (T2DM) and normo-glycemic patients.
Materials and methods
A total of 31 patients, 15 of which diagnosed with T2DM (HbA1c > 6.5) and 16 normo-glycemic patients received narrow diameter implants in the posterior mandible or maxilla. During the 3-month healing period, soft-tissue perfusion was monitored via Laser-Doppler flowmetry. Peri-implant fluid (PICF) was harvested and analyzed for concentrations of interleukin-1ß (IL-1ß), interleukin-23 (IL-23), interleukin-17 (IL-17) and granulocyte colony-stimulating factor (G-CSF) by a multiplex, bead-based immunoassay.
Results
Microcirculatory perfusion patterns during wound healing exhibited no significant differences throughout the observation period. IL-1ß concentrations were expectedly elevated during the early phases of wound healing. At the first visit after surgery, IL-23 concentrations were significantly higher in implants of diabetic patients. This difference was diminished over the course of the observation period. For the other tested analytes, no differences were observable between both groups.
Conclusion
Wound healing after implant surgery was similar in T2DM and healthy patients. Hydrophilic-surface titanium-zirconium implants with reduced diameter may be considered for implant therapy of Diabetes mellitus type II patients.

Abstract
Background: Hearing loss is the fourth leading cause of disability in the world. The growing trend of this disease has made it a serious public health issue that requires well-designed and coordinated measures at the global, regional, and local levels. The current cohort study aimed to estimate the prevalence and incidence of different types of hearing loss and identify the risk and protective factors in the study population.Methods: Hoveyzeh ear cohort (HEC) is a population-based cohort study that focuses on the audiological profile of 10,009 participants 35-70 years old who will recruit between May 2017 to January 2023. This study is conducted in the enrolment phase consisting of three steps registration, audiological assessments, and follow-up phase. Results: A total of 1845 participants, aged 35-70 years old, that have been registered in the Hoveyzeh Cohort Study (HCS) are included in this pilot study. Our findings revealed that 947 participants (51.3%) had some degree of hearing loss in the pilot study. The prevalence of hearing loss was significantly correlated with demographical and socioeconomic variables including age, sex, educational level, marital status, wealth status, skilled levels, Townsend index, and smoking (p-value<0.05). We also found a significant correlation between the prevalence of hearing loss with clinical variables including tinnitus sensation, dizziness sensation, and history of diabetes, hypertension, cardiovascular disease, ear surgery, head trauma, and noise exposure (p-value<0.05). However, no significant correlation was found between the prevalence of hearing loss and the type of residence, wealth index, and alcohol consumption.Conclusion: Our results demonstrated that hearing loss is an important contributor to the burden of chronic disability in Iran. There is a wide range of demographic, socio-economic, and medical parameters that affect the consequences of hearing loss. This study can provide the context of many studies in the field of hearing.
A Detailed Macroscopic Scoring System for Experimental Post-Traumatic Osteoarthritis in the Equine Middle Carpal Joint
Authors: Andersen Camilla , Jacobsen Stine , Walters Else Marie , Lindegaard Casper 
Published: May 2022

Abstract
Objective: Osteoarthritis (OA) is a significant problem in both people and horses. Experimental models of equine carpal OA have been used to investigate the pathogenesis of OA and to evaluate potential therapeutic candidates. A 5-scale scoring system (OARSI) for macroscopic pathological cartilage changes already exists, but there is a need for a scoring system with better differentiation of severity. The aim of this study was therefore to develop and validate such a scoring system. Results: New scoring system were developed for cartilage erosions (Copenhagen Equine Total Cartilage Score, CEqTCS) along with synovial membrane pathology and osteochondral fragment healing (Copenhagen Equine Carpal Osteoarthritis Score, CEqCOAS). For the CEqTCS there was excellent intraclass agreement (ICC=0.993; CI: 0.985-0.996; p = 1.08e-31) and consistency (ICC=0.992; CI: 0.985-0.996; p=4.61e-31), as well as excellent interclass agreement (ICC=0.974; CI: 0.948-0.987, p=2e-22) and consistency (ICC=0.973; CI: 0.946-0.987; p=2.77e-22), while the OARSI system had moderate (k = 0.47) and weak (k = 0.28) inter- and intra-class agreement, respectively. The OARSI score and the CEqTCS correlated excellently, but every OARSI grade encompassed a wide range of CEqTCS grades. The new score for assessment of equine OA provides means to a better differentiation of OA changes than the existing OARSI system.

Published: May 2022

Abstract
Background: Increased systematic pro-inflammatory cytokines is the main cause of the inflammatory conditions of the hospitalized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected patients. In this project serum levels of IL-29 and whole blood levels of microRNA-185-5p (miR-185-5p) were evaluated in the hospitalized SARS-CoV-2 infected patients.Methods: This project was performed on the 60 hospitalized SARS-CoV-2 infected patients and 60 healthy controls to evaluate IL-29 and miR185-5p expression levels. IL-29 expression was explored using enzyme linked immunoassay (ELISA), while miR185-5p was evaluated using Real-Time PCR techniques.Results: The results demonstrated that neither IL-29 serum levels nor relative expressions of miR-185-5p were significantly different between patients and healthy controls. Conclusion: Due to the results that are presented here, systematic levels of IL-29 and miR-185-5p cannot be considered as the main risk factors for induction of inflammation in the hospitalized SARS-CoV-2 infected patients.
