Authors: Oluwatosin Adedoyin , Akporhonor Blessing Amina 
Published: November 2021

Background of the study: It is the responsibility of every school library to promote and support the National Policy of Education by providing equitable school library resources.
Purpose: This study investigates the availability and usage of school library resources as predictors of reading habits among secondary school students in Oredo Local Government (LG) of Edo state, Nigeria.
Method: Descriptive survey design was adopted for the study. The population comprises of 362 students in Senior Secondary Students III (SSS3) in two public and two private senior secondary schools in Oredo LG, Edo state, Nigeria. Stratified random technique was used to select the four schools and 200 copies of questionnaires were administered to the respondents of which only a total of 190 copies of questionnaire were returned which represents 95% return rate.
Findings: Findings revealed that most of the sampled schools have library resources; however most of the resources were obsolete. Results show that most of the respondents do not make use of the resources regularly and that the respondents are majorly interested in text related to their subject in school. It was discovered that none of the schools have a trained librarian working in their libraries.
Conclusion: The study established that availability and usage of library resources cannot effectively predict the reading habit of secondary school students in Oredo LG, Benin-City.

Authors: Arnold Matthew C.A. , Zhao Sarah , Doyle Ruben J. , Jeffers Jonathan R.T. , Boughton Oliver R. 
Published: November 2021

Background:
Power tools are an integral part of orthopaedic surgery but have the capacity to cause iatrogenic injury. With this systematic review, we aimed to investigate the prevalence of iatrogenic injury due to the use of power tools in orthopaedic surgery and to discuss the current methods that can be used to reduce injury.

Methods:
We performed a systematic review of English-language studies related to power tools and iatrogenic injuries using a keyword search in MEDLINE, Embase, PubMed, and Scopus databases. Exclusion criteria included injuries related to cast-saw use, temperature-induced damage, and complications not clearly related to power-tool use.

Results:
A total of 3,694 abstracts were retrieved, and 88 studies were included in the final analysis. Few studies and individual case reports looked directly at the prevalence of injury due to power tools. These included 2 studies looking at the frequency of vascular injury during femoral fracture fixation (0.49% and 0.2%), 2 studies investigating the frequency of vertebral artery injury during spinal surgery (0.5% and 0.08%), and 4 studies investigating vascular injury during total joint arthroplasty (1 study involving 138 vascular injuries in 124 patients, 2 studies noting 0.13% and 0.1% incidence, and 1 questionnaire sent electronically to surgeons). There are multiple methods for preventing damage during power-tool use. These include the use of robotics and simulation, specific drill settings, and real-time feedback techniques such as spectroscopy and electromyography.

Conclusions:
Power tools have the potential to cause iatrogenic injury to surrounding structures during orthopaedic surgery. Fortunately, the published literature suggests that the frequency of iatrogenic injury using orthopaedic power tools is low. There are multiple technologies available to reduce damage using power tools. In high-risk operations, the use of advanced technologies to reduce the chance of iatrogenic injury should be considered.

Published: November 2021

Background:
The purpose of this study was to describe the prevalence of lumbar spine degeneration in adult individuals who had undergone lumbar disc herniation surgery during adolescence.

Methods:
Twenty-three individuals who had been surgically treated for lumbar disc herniation as adolescents (≤18 years of age) participated in this study at a mean of 13.8 years (range, 8.6 to 20.4 years) after the surgery; they were matched for age and sex to 23 controls without any known previous disc herniation or spinal surgery. Magnetic resonance imaging included sagittal T1-weighted, T2-weighted, and short tau inversion recovery (STIR) sequences of the lumbar spine. Disc degeneration was assessed with the Pfirrmann grading system. Changes in the vertebral end plate and body were assessed according to Modic changes and total end plate (TEP) score. Patient-reported outcome measures included the Oswestry Disability Index, a visual analog scale (VAS) for leg and back pain, the EuroQol-5 Dimension-3 Level (EQ-5D-3L) questionnaire, and the mental and physical component summary scores of the Short Form (SF)-36. Statistical analyses were made with the chi-square test and the Welch-Satterthwaite t test.

Results:
Compared with the controls, the cases that underwent surgery had a higher prevalence of the following: severe degeneration according to the Pfirrmann grading system at the L4-L5 (p = 0.007) and L5-S1 (p = 0.002) levels, Modic changes at the L4-L5 (p = 0.022) and L5-S1 (p = 0.026) levels, and a TEP score of ≥6 at the L5-S1 level (p = 0.001). The surgical cases had a significantly worse patient-reported outcome compared with the controls (all p ≤ 0.010), with the exception of the VAS for leg pain (p = 0.093) and the mental component summary score of the SF-36 (p = 0.844).

Conclusions:
Lumbar disc herniation surgery that was performed during adolescence was associated with more frequent lumbar spine degeneration and lower health-related quality of life in adulthood when compared with the control group.

Published: November 2021

Abstract
Recently, CO2 geological sequestration combined with enhancing deep saline water/brine recovery is regarded as a potential strategic choice for reduction of CO2 emissions. This technology not only achieves the relatively secure storage of CO2 which was captured during industrial processes but also can enhance the recovery of water for drinking, industrial, and agricultural utilization. However, the impact of CO2-water-rock reactions on the shale reservoir in the system is unclear and the sealing performance of mudstone caprock has not been investigated. For analyzing the mechanism of mineral alteration in the shale reservoir, a three-dimensional injection-production model in the double-fractured horizontal well pattern is established according to actual parameters of shale and mudstone layers. In addition, mineral alteration was characterized and caprock sealing performance was also assessed. Numerical results showed that the presence of CO2 can lead to the dissolution of k-feldspar, oligoclase, chlorite, and dolomite and the precipitation of clay minerals such as kaolinite, illite, and smectite (Ca-smectite and Na-smectite). Due to positive ion released by dissolved primary minerals, the precipitation of secondary carbonate occurs including ankerite and dawsonite, which induces the mineral sequestration capacity of the shale reservoir. The amount of CO2 sequestration by mineral is 51430.96 t after 200 years, which equals 23.47% of the total injection (219145.34 t). Besides, the height of the sealing gas column is used for evaluating the sealing performance of the shale-mudstone interface. Results show that the height of the sealing gas column at the interface above the injection well is lower but the maximum value of CO2 gas saturation is only 0.00037 after 200 years. The height of the sealing gas column at the interface is greater than 800 m, which can be classified as level II and guarantee the security of the CO2 storage. The analysis results provide reliable guidance and reference for the site selection of CO2 geological sequestration.

Published: November 2021

Abstract
Objective: To compare the effects of aminosalicylic acid, glucocorticoids and immunosuppressive agents on the expression levels of multidrug-resistant genes in ucerative colitis (UC) patients, aiming to provide theoretical and therapeutic basis for the diagnosis, treatment and prevention of UC.Methods: Fresh specimen of colon mucosal tissues pathological mucosal tissues under endoscopy or postoperative pathological biopsy tissues were collected from 148 UC patients and then prepared for subsequent experiment.Immunohistochemical staining was conducted to detect the distribution site and pattern of P-glycoprotein （P-gp）. The effects of ASA glucocorticoids and immunosupresive agents on P-gp were statistically compared.The expression levels of Multidrug resistance gene （MDR1）mRNA before and after corresponding treatment were quantitatively measured by using RT-PCR. In addition, the effects of three agents upon MDR1 mRNA were also comparatively analyzed.Results: Administration of 5-aminosalicylic acid (5-ASA) drugs were not correlated with the expression of multidrug resistance genes in UC, whereas delivery of glucocorticoids and immunosuppressant drugs was positively correlated with the expression profile. The expression levels of MDR1 gene and its product P-gp were significantly up-regulated in patients who were nonresponsive to glucocorticoids and immunosuppressant agents.Conclusions: Overall, the findings in the present study demonstrate that 5-ASA exerts no effect upon the expression levels of MDR1 and its product P-gp in patients diagnosed with UC. Nevertheless, administration of glucocorticoids and immunosuppressant drugs can up-regulate the expression levels of MDR1.

Abstract
Background: Aging individuals are prone to sarcopenic obesity (SO). SO is associated with higher risks of low physical function, metabolic diseases, cardiovascular disease (CVD), and mortality. Worldwide diagnostic criteria for SO and its cutoff values have not yet been established. In this study, from among obesity- and sarcopenia-evaluated indices, we determined a combined index most associated with the accumulation of CVD risk factors in obese patients.Methods: In this cross-sectional study, we evaluated body composition using a multifrequency bioelectrical impedance analysis device and measured handgrip strength in 188 obese patients (73 men and 115 women). We selected each index most associated with the accumulation of CVD risk factors among obesity- (body mass index, percentage body fat, or waist circumference [WC]) and sarcopenia-evaluated indices (skeletal mass index, handgrip strength, or muscle quantity [MQ]), respectively. We then classified obese patients into four groups (group C, control; group O, obesity alone; group S, sarcopenia alone; and group SO, sarcopenic obesity) using the two selected indices with each median value and compared the CVD risk score, the number of concomitant CVD risk factors, among the four groups.Results: Based on the dichotomous comparison, WC and MQ were selected as the indices most associated with CVD risk factor accumulation. The CVD risk score was significantly higher in groups S and SO as compared with group C (1.94 ± 0.80, 1.95 ± 0.91 vs. 1.41 ± 0.84, all p < 0.05). Odds ratios for CVD risk scores ≥2 were significantly higher in groups S, O, and SO compared with group C (4.78 [95% confidence interval {CI} 1.79-12.81], p = 0.002; 3.28 [95% CI 1.37-7.88], p = 0.008; 3.92 [95% CI 1.74-8.81], p = 0.001; respectively). Furthermore, odds ratios for CVD risk scores = 3 were significantly higher only in group SO compared with group C (4.29 [95% CI 1.49-12.33], p = 0.007).Conclusion: In obese patients, WC and MQ were most associated with the accumulation of CVD risk factors, respectively. Furthermore, classification using the combined index of WC and MQ reflects the accumulation of CVD risk factors in obese patients, regardless sex and age.

Effective Antioxidant activity of Phytic acid Prevents Isoproterenol-Induced Myocardial Infarction in Albino wistar Rats
Authors: BRINDHA E 
Published: November 2021

Abstract
This study aimed to evaluate the preventive effect of phytic acid on cardiac markers, blood glucose, total proteins, albumin/globulin (A/G) ratio, serum uric acid, serum iron, and plasma iron binding capacity in isoproterenol (ISO)-induced myocardial infarction (MI) in male Wistar rats. Rats subcutaneously injected with ISO (85 mg/kg) at an interval of 24 h for 2 days showed a significant increase in the degrees of cardiac troponin T (cTnT), intensity of the bands of lactate dehydrogenase (LDH)-isoenzyme (LDH1 and LDH2) and the activities of cardiac marker enzymes such as creatine kinase-MB (CK-MB), creatine kinase (CK), lactate dehydrogenase (LDH), aspartate transaminase (AST) and alanine transaminase (ALT) in serum with subsequent decrease in the activities of CK, LDH, AST and ALT in the heart. ISO-induced rats showed a significant increase in blood glucose, serum uric acid, serum iron and a decrease in the levels of total proteins, A/G ratio and iron binding capacity. Pretreatment with phytic acid (25 and 50 mg/kg) daily for a period of 56 days positively altered the levels of cTnT, intensity of the bands of the LDH1 and LDH2-isoenzyme and the activities of cardiac marker enzymes, and other biochemical parameters. Thus, phytic acid possess cardioprotective effect in ISO-induced oxidative stress in rats.

Published: November 2021

Abstract
This article focuses on the prediction of forming trajectory and process optimization during the forming process for the variable curvature tubes. Firstly, through cubic B-spline interpolation, the geometric characteristics of the axis of the target tube are obtained. An overall tube is "separated and then integrated", and the relationship between geometric parameters and processing parameters is established to obtain the initial process parameters. Based on the Extended Kalman Filter (EKF) algorithm, the motion model and observation model of tube forming using simulation are presented section by section, and the relevant calculation and analysis are carried out. The forming trajectory has been predicted and the processing parameters are optimized during the processing process, in which the effectiveness of the processing optimum scheme is illustrated.

Authors: Wronka Iwona , Kliś Katarzyna 
Published: November 2021

Abstract
Objectives

to analyse the association between the degree of air pollution (suspended particulate matter, sulphur dioxide, benzopyrene levels) in the location of residence during childhood and adolescence and the age at menarche
Methods

Anthropometric measurements were performed, and questionnaire data were collected from 1,257 women, aged 19-25 years
Results

Negative relationships between age at menarche and suspended particulate matter as well as nitrogen levels were found. A similar trend was observed in an analysis of the relationship between age at menarche and the complex air pollution index. The tendency for age at menarche to decrease together with worsening air quality was also visible after adjusted for socioeconomic status. Girls exposed to high suspended particulate matter levels were characterised by higher risk of early age at menarche.
Conclusion

High levels of air pollution are related to younger age at menarche and the risk of the menstruation onset below 11 y.

Published: November 2021

Abstract
Background
Postpartum depression (PPD) is a common mood disorder with increasing incidence year by year. However, the dynamic changes in local neural activity remain unclear. In this study, we utilized the dynamic amplitude of low-frequency (dALFF) to investigate the abnormal temporal variability of local neural activity.
Methods
Twenty-four patients with PPD and nineteen healthy postpartum women controls (HCs) matched for age, education level and body mass index were examined by resting-state functional magnetic resonance imaging (rs-fMRI). A sliding-window method was used to assess the dALFF, and a k-means clustering method was used to identify dALFF states. Two-sample t-test was used to compare the differences of dALFF variability and state metrics between PPD and HCs. Pearson correlation analysis was used to analyze the relationship between dALFF variability, states metrics and clinical severity.
Results
(1) Patients with PPD had lower variance of dALFF than HCs in the cognitive control network, cerebellar network, and sensorimotor network. (2) Four dALFF states were identified, and the number of transitions between the four dALFF states increased in the patients compared with that in HCs. (3) Multiple dALFF states were found to be correlated with the severity of depression. The variance of dALFF in the right middle frontal gyrus was negatively correlated with the Edinburgh postnatal depression scale score.
Conclusion
This study provides new insights into the brain dysfunction of PPD from the perspective of dynamic local brain activity, and highlights its important role in understanding the neurophysiological mechanisms of PPD.

Published: November 2021

Abstract
A tightly-coupled integrated navigation system (TCINS) for hypersonic vehicles is proposed when the satellite signals are disturbed. Firstly, the architecture of the integrated navigation system for the hypersonic vehicle is introduced. This system applies fiber SINS, BeiDou satellite receiver (BDS) and SOPC missile-born computer. Subsequently, the SINS mechanization for hypersonic vehicle is presented. The J2 model is employed for the normal gravity of the near space. An algorithm for updating the attitude, velocity and position is designed. State equations and measurement equations of SINS/BDS tightly-coupled integrated navigation for hypersonic vehicle are given, and a scheme of validity for satellite data is designed. Finally, the SINS/BDS tightly-coupled vehicle field tests and hardware-in-the-loop (HWIL) simulation tests are carried out. The vehicle field test and HWIL simulation results show that the heading angle error of tightly-coupled integrated navigation is within 0.2°, the pitch and roll angle errors are within 0.05°, the maximum velocity error is 0.3m/s, and the maximum position error is 10m.

Abstract
To address the increasing cancer burden in Indiana, a telementoring program using the Extension for Community Healthcare Outcomes (ECHO) model focusing on cancer prevention, screening, and survivorship care, was deployed in September 2019 to guide best-practice care to primary care providers (PCPs). We utilized Moore’s Evaluation Framework for Continuing Medical Education to evaluate the program's educational outcomes. We collected 22 semi-structured interviews and 30 anonymous one-time surveys from the program participants (hub and spoke members) and the target audience. During the first year, there was an average of 12 non-PCP professionals and 2.5 PCPs come to each session. In spite of a relatively low PCP participation, the program overall received very positive satisfaction and feedback of their improvement in knowledge, confidence and practice. There are three features that both program participants and target audience valued in the Cancer ECHO: a conversational format, gaining real-life experiences, and support from a professional interdisciplinary community. Our study also discovered the PCP’s resistance to didactics focused on prevention and screening, their preference on case discussion part about survivorship care but they do not have enough cases to present. Our study showed that the Cancer ECHO program could be an effective educational means in improving the cancer control capacity, especially to the PCPs. The program strengths suggested a unique role of the ECHO model among the existing physician-targeting cancer control interventions. A further study is warranted to explain the discrepancy between the program’s strengths and a relatively low PCP adoption.
