Published: August 2022

The use of organic amendments is popular these days therefore we conducted a study on biochar in various North Indian region soils under pot culture to evaluate the changes in soil characteristics. Four types of soils taken for 75 days during Kharif and Rabi season were studied, out of which Soil-1 is slightly acidic while Soil-2 to Soil-4 are alkaline. The soil samples were collected thrice at the interval of 25 days using standard procedures and analyzed for various macronutrients (pH, EC, OC, N, P, and K) essential for plants in the laboratory. The change in status of available NPK in soils and other soil properties like pH, electrical conductivity (EC), and organic carbon (OC) content due to inoculation of biochar was assessed. Results reveal that all treatments having biochar leads to an increase in the content of available N, P, and K together with OC. There recorded a slight elevation in EC initially at 25th DAI due to its inoculation. The pH during the initial period had reduced but later on rise as the number of DAI increased.

Introduction: Human head lice infest people worldwide and are most prevalent in children. Outbreaks of head lice more commonly affect children 3 to 12 years old, with girls being affected more commonly than boys. The aim is to study the factors affecting transmission of the disease among the school children in villages in Benghazi - Libya.
Patients and Methods: In a cross-sectional study in western region of Benghazi, 556 students in three schools from Alhlys, Alatry and Abofakra regions were enrolled. The ages of children ranged from 6 to 13 years. Data collected include socio-demographic characteristics of the students, sex, age, school and hair were examined individually for head lice infestation in a separate room. Descriptive analysis and Chi-square test was used to determine the statistical significance of p-value ≤ 0.05.
Results: The data were collected on 556 students from the 3 villages: 39.7% from Al-Helys, 28.8% from Al-Tarya and 31.5% from Abofakra regions. The age of children ranged from 6 to13 years. Female children were more than 50%. The mean of family size was 7±2 persons, number of bedroom in houses ranged from 1-5 rooms.. Sharing of personal equipment such as hair comb and linen was reported in 33.5% of families. Pediculosis capitis manifestation was reported in 26.3% of the participants. The prevalence of pediculosis capitis was 19.5% in Al-Helys, 35.6% in Al-Tarya and 26.3% in Bo-Fakra; this difference was statistically significant (p<0.05) . The prevalence of pediculosis capitis in males was 10.2%, while in females was 41.8% , this difference was highly statistically significant (p =0.0001) The highest prevalence of pediculosis capitis was in age of 11 years old (42.9%), followed by age of 10 years old (36.6%). There were no reported cases at the age of 6 and 13 years. There was no effect of parent occupation or education level on pediculosis infestation transmission.
Conclusion: The present study revealed that, Pediculosis capitis was prevalent in school children, more in females. Furthermore pediculosis was higher in certain villages than others.

Background: Endoscopic third ventriculostomy is surgical procedure that is operated for management of obstructive hydrocephalus and regained popularity with large number of promising results.
Aim: To evaluate the outcome of Endoscopic Third Ventriculostomy by correlation between clinical outcome and MRI cerebrospinal fluid flowmetry postoperatively.
Patients and Methods: This study was conducted in Department of Neurosurgery at Tanta University from January 2018 to January 2020. It included 25 patients with triventricular hydrocephalus with different etiologies. All patients were subjected to history taking, complete physical, neurological examination, routine preoperative laboratory investigations, radiological investigations e.g. non contrast CT and MRI of the brain. Patients underwent surgery according to the exact cause of hydrocephalus, which was known and identified by neuroimaging and endoscopic third ventriculostomy. Outcome assessment was done by neurological evaluation for resolution of their clinical symptoms and a shunt free stable clinical status. Patients were evaluated once weekly for the first month then monthly for the first 3 months and the patients were finally evaluated at the end of the 6th month postoperatively.
Results: Of 25 patients, 9 patients (36%) with Aqueduct stenosis, 1 patient (4%) with Brain stem glioma, 1patient (4%) with Brain stem tumor, 5 patients (20%) with PF tumor, 6 patients (24%) with Pineal tumor, 1patient (4%) with Thalamic glioma, 1patient (4%) with Tectal glioma and 1only one patient (4%) with Chiari 1 malformation.92% had Patent ETV stoma with adequate flow: OFA value >75 μL, 8% had Patent ETV stoma with low flow: OFA value from 25 up to <75 μL. The mean Headache VAS Preoperative was 6.08 (±1.04 SD). the baseline mean Evan's Ventricular ratio was 0.34 ± 0.02 and 60% of cases had papilledema. Blurring of vision was present in 60% of cases, headache in 100% of cases and vomiting was present in 60% of cases.
Conclusions: Dynamic MRI of CSF flow provides reliable and immediate information on the efficacy of ETV, in addition to the flow-void presence at the level of the 3rd ventricle floor fenestration in both midsagittal and perpendicular plane, even in the absence of phase-contrast techniques which is significantly correlated with clinical signs and symptoms improvement in the patients.

Published: August 2022

Background: Acute Myeloid Leukemia (AML) is the most common acute leukemia affecting adults, and its frequency increases with age. CD47 may not only be valuable biomarker to recognize leukemic stem cells (LSCs) but also may denote a clinically relevant pathogenetic factor of disease. The aim of this work was to study the expression of CD47 in patients with acute myeloid leukemia and to identify its role as a prognostic marker.
Methods: The present study was carried out on 40 newly diagnosed untreated AML patients. AML patients were divided into two groups according to status of expression: Negative Group including patients expressing CD47 on less than 20% of their blast cells (28 patients) and positive Group including patients expressing CD47 on 20 % or more of their blast cells (12 patients). All patients were subjected to laboratory investigation for detection of CD47 expression m bone marrow aspirate and venous blood samples of AML patients by flowcytometry.
Results: Complete remission was found in 2 patients (16.67%), 6 patients relapsed (50%) and 4 patients died (33.33%) of 12 cases that had exhibited CD47 positive expression. Kaplan-Meier Survival curve shows significant higher overall survival and disease-free survival in negative CD47 expression group than in positive CD47 expression group.
Conclusions: Positive CD47 expression levels are associated with a poor outcome in AML patients and its expression can be easily determined in routine flow cytometric analysis. Therefore, it should be regularly investigated as a bad prognostic factor for the assessment of AML patients.

Background: Ankle impingement is the painful mechanical restriction of complete ankle range of motion caused by an osseous or soft-tissue deformity. Ankle impingement syndromes are prevalent and significant post-traumatic sources of morbidity in professional and amateur sports. The aim of this research is to evaluate the role of Magnetic Resonance Imaging (MRI) in diagnosis of ankle impingement syndromes.
Methods: This prospective study was performed on 40 consecutive patients aged from 20 to 55 years old, with clinical diagnosis of ankle impingement, 21 (52.5%) of them were males and 19 (47.5%) were females. All patients were subjected to full history taking [personal history, history of present illness (onset, course and duration; pain, swelling, limitation of movement, and other symptoms)], clinical Examination was carried out by the colleagues in the Orthopaedic department and MRI examination where all patients were examined with closed superconductive 1.5 T magnet (GE SIGNA Explorer), using the extremity coils.
Results: 26 out of the 28 cases with clinically suspected posterior impingement were correctly diagnosed by MRI (sensitivity of 92.86%, specificity of 100% and accuracy of 92.86%) and other two cases showed synovial effusion. 3 out of the 4 cases with clinically suspected anterolateral impingement were correctly diagnosed by MRI (sensitivity of 75%, specificity of 100% and accuracy of 75%) and other case showed sinus tarsi. All the 4 cases with clinically suspected anterior, anterolateral impingement were correctly diagnosed by MRI (sensitivity of 100%, specificity of 100% and accuracy of 100%). Totally, MRI sensitivity in diagnosis impingement was 92.5%, specificity was 100% and accuracy was 92.5%).
Conclusions: MRI exhibits excellent overall sensitivity, specificity, and accuracy in the diagnosis of ankle impingement. MRI displays rather definite anatomic and pathologic details, with outstanding outlining of both bony and soft tissue structures. Moreover, it assists in the exclusion of other mimic similar conditions.

Published: August 2022

Although sentiment analysis for COVID-19 tweets is becoming popular, no study has mined a sentiment other than polarity. This study aims to extract ‘disaster’ sentiment by using various machine learning models, statistically validate sentiment markers extracted by deep learning, and discuss the potentials of ‘disaster’ as valid sentiment marker.
A total of 7,613 disaster tweets from Kaggle site were utilized to train nine machine learning models. A total of 15,619 tweets in English sent from USA were downloaded using streaming API with keywords of Covid, and Omicron, respectively and were classified into disaster/non-disaster categories using the four best performing models: MNB, deep learning, USE and BERT. Principal component analysis, correlation analysis and regression analysis were performed to determine the psychometric properties.
Cronbach Alpha for 13 sentiment markers was 0.71. All 4 machine learning markers were loaded in a factor. A higher level of unfavorable emotions (e.g., fear), a lower level of favorable emotions (e.g., joy), and a higher level of negative polarity were found during surging Omicron variants than early onset of COVID-19. The higher frequency of disaster tweets was found during surging Omicron variants than the early onset of COVID-19.
Our study revealed that disaster tweets were characterized to be a higher level of unfavorable emotions and negative polarity, and a lower level of favorable emotions. Since disaster as a sentiment marker was evidently reliable and valid, it should be a part of the sentiment analysis in describing the global health issues.
Therapeutic Error: Types and Prevention Strategies and Focus about "Look Alike/Sound Alike" and "High Risk" Drugs
Authors: Marovino Edoardo , Morgillo Amelia , Mancino Naomi , Di Feo Veronica , Genito Emanuela 
Published: August 2022

Introduction: Therapeutic errors are among the main causes of drug-related problems, in terms of enhanced toxicological or reduced therapeutic effect, and concern all stages of the drug chain, from manufacturing to prescription, dispensing and administration. Everyone, pharmacists and doctors in all settings, should be aware of how to prevent and manage them and which drugs are at greatest risk. In this article we will focus on LASA (look alike/sound alike), on FAR (high-risk drugs) and on the guidelines especially for prevention.
Methods: The article is a minireview that was written by research in paper and online on PubMed and Embase. We performed a search of any publications available in these databases between the years 1990 and 2022, using the key words: therapeutic errors, misuse / diversion of drugs, drug poisoning. After a review of the titles and abstracts, the articles chosen were considered relevant in providing evidence of the problem. We also added personal knowledge about the topic of the article and used some paper documents.
Discussion and Conclusions: Most of the errors in therapy occur during administration, due to errors in doses, posology or interactions or incorrect manipulations of pharmaceutical forms, and in dispensing, due to incorrect interpretation of the prescription or confusion on the packaging in the case of LASAs. Pharmacists and doctors but also patients themselves should pay attention to the time of prescription and doctors to the drug history not only for interactions but also to avoid making mistakes in patients who take drugs with names or packages similar to the one described above. Moreover, attention must be paid in writing the prescription, in dosage, and pharmaceutical forms. Particular attention should be paid to handling by children and to avoiding any misuse of the medicines themselves.

Aim: The physiological transformation of women from pre to post-menopause is often accompanied with many changes in biochemical parameters which instigates some physiological alterations in the body system of the women. Research has shown some alterations in trace mineral nutrition and metabolism following attainment of menopause. This study was aimed at investigating the trace mineral status in premenopausal and postmenopausal women in Port-Harcourt metropolis.
Methods: This study was carried out among fifty (50) apparently healthy postmenopausal women aged between 45-65 years and twenty (20) premenopausal women aged between 22-38 years. Five milliliters (5 mL) of venous blood was withdrawn from each participant after an informed consent was obtained. Blood samples were emptied into a plain tube and allowed to clot. Samples were spun and serum separated into separate tubes and stored at -200C until analysis. Serum levels of trace mineral magnesium, calcium, zinc and copper were evaluated using Atomic absorption Spectrophotometer ELICO, India, Model No. SL173. Data generated were analyzed using Graph-Pad Prism version 8.0.2 and p < 0.05 was considered significant.
Results: Result reveal a significant reduction in serum levels of magnesium in post-menopausal women (0.39± 0.29 mmol/L) when compared with the premenopausal women (1.14 ± 0.54 mmol/L) (P< 0.0001). Similarly, the serum zinc declined in postmenopausal women 6.12 ± 6.42mmol/L compared with the premenopausal women 23.02± 12.25mmol/L (P< 0.0001). However, serum levels of copper and calcium were not statistically different in the two groups (p> 0.05).
Conclusion: The findings in this work suggests a decrease in serum zinc and magnesium levels in postmenopausal women, hence dietary supplements of these trace minerals is advocated for post-menopausal women.

Purpose: Entrepreneurship is one of a country's economic engines, particularly in developing countries. Sri Lanka was sliding down in Global Entrepreneurship Index. The main purpose of this study is to investigate the key determinants to the establishment of digital entrepreneurial ecosystem for deriving solutions to the contemporary issues in entrepreneurship in Sri Lanka.
Method: Quantitative research approach was employed. Primary data were collected through a structured questionnaire, using 234 undergraduates who are following entrepreneurship degree programs in the selected universities. Acknowledging the literature, digital entrepreneurship, infrastructure, user citizenship and marketplace were selected as the determinants of establishing the digital entrepreneurship ecosystem.
Findings: Multiple regression analysis results indicated that digital entrepreneurship, digital infrastructure, digital user citizenship and digital marketplace have a significant influence on the establishment of the digital entrepreneurship ecosystem. Digital entrepreneurship has the greatest effects on the establishment on digital entrepreneurship ecosystem, followed by digital infrastructures. The digital marketplace has the smallest effect on establishing the digital entrepreneurship ecosystem.
Research Implication: Findings of the study would be useful in monitoring the involvement of digital technologies in entrepreneurship. Local, provincial, and national governments can play an important role in encouraging digital entrepreneurship and digitalization among potential entrepreneurs.
Future Research Suggestion: The study focused only on the effect of digital infrastructure, users and marking aspects on the establishment of the digital entrepreneurial ecosystem. The developing countries like Sri Lanka, the lack of law, investment hunger, corruption, and gaps in the low of innovation environment and inefficiency of administration agents and business forms are impeding the progress of the enormous preference for innovation and digital technology. Further research should be conducted to investigate how these factors play a role in this model.

Published: August 2022

AbstractMicrocarrier‐based mesenchymal stem cells (MSCs) delivery have attracted increasing attention in acute liver failure (ALF) therapy, while there is still room for improvement in terms of improving cell loading efficiency, enhancing anti‐inflammatory features, and controlling cell release. Here, novel lipopolysaccharide (LPS)‐composited magnetic‐thermal responsive inverse opal particles (MIOPs) are presented for the delivery of MSCs. The MIOPs are composed of a chitosan inverse opal skeleton filled with a hydrogel containing LPS, poly(N‐isopropylacrylamide), and Fe3O4 nanoparticles. Benefitting from the biocompatible chitosan component and the huge specific surface area, the resultant MIOPs can capture MSCs in a nondestructive way. Furthermore, LPS can be released from the MIOPs under the stimulation of an alternating magnetic field, by which the MSCs are activated to gain the feature of “trained immunity.” Moreover, this process can be monitored in real‐time by the structural color change of the MIOPs. With that, the MSCs‐laden MIOPs are employed in rats with ALF, and they exhibit obvious anti‐inflammatory and therapeutic efficacy superior to untrained MSCs. These performances make the MIOPs a distinctive cell delivery platform for clinical tissue recovery applications.

Published: August 2022

AbstractEutectic gallium–indium (EGaIn), a liquid metal with a melting point close to or below room temperature, has attracted extensive attention in recent years due to its excellent properties such as fluidity, high conductivity, thermal conductivity, stretchability, self‐healing capability, biocompatibility, and recyclability. These features of EGaIn can be adjusted by changing the experimental condition, and various composite materials with extended properties can be further obtained by mixing EGaIn with other materials. In this review, not only the are unique properties of EGaIn introduced, but also the working principles for the EGaIn‐based devices are illustrated and the developments of EGaIn‐related techniques are summarized. The applications of EGaIn in various fields, such as flexible electronics (sensors, antennas, electronic circuits), molecular electronics (molecular memory, opto‐electronic switches, or reconfigurable junctions), energy catalysis (heat management, motors, generators, batteries), biomedical science (drug delivery, tumor therapy, bioimaging and neural interfaces) are reviewed. Finally, a critical discussion of the main challenges for the development of EGaIn‐based techniques are discussed, and the potential applications in new fields are prospected.

AbstractElectrocatalytic oxidation of 5‐hydroxymethylfurfural (HMF) provides an efficient way to obtain high‐value‐added biomass‐derived chemicals. Compared with other transition metal oxides, CuO exhibits poor oxygen evolution reaction performance, leading to high Faraday efficiency for HMF oxidation. However, the weak adsorption and activation ability of CuO to OH− species restricts its further development. Herein, the CuO–PdO heterogeneous interface is successfully constructed, resulting in an advanced onset‐potential of the HMF oxidation reaction (HMFOR), a higher current density than CuO. The results of open‐circuit potential, in situ infrared spectroscopy, and theoretical calculations indicate that the introduction of PdO enhances the adsorption capacity of the organic molecule. Meanwhile, the CuO–PdO heterogeneous interface promotes the adsorption and activation of OH− species, as demonstrated by zeta potential and electrochemical measurements. This work elucidates the adsorption enhancement mechanism of heterogeneous interfaces and provides constructive guidance for designing efficient multicomponent electrocatalysts in organic electrocatalytic reactions.
