Authors: Wan Xianwen , Gong Haixia , Leng Hongxia , Zhang Yulian
Published: September 2024

Purpose: To investigate the effect of remimazolam (Re) on oxygen glucose deprivation/reoxygenation (OGD/R) model, and to elucidate the mechanism of action.
Methods: The neuron cells were treated with OGD/R. MTT assays were performed to confirm The effect of Re on cell viability was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, while flow cytometry (FCM) assay was conducted to determine the apoptosis of OGD/R cells. Immunostaining assay and enzyme-linked immunosorbent assay (ELISA) were used to evaluate the effects of Re on mitochondria damage, while immunoblot assay was used unravel its mechanism of action.
Results: Remimazolam (Re) significantly enhanced OGD/R-induced neuronal survival (p < 0.05). In addition, it significantly inhibited OGD/R-induced neuronal apoptosis, and OGD/R-induced neuron mitochondrial damage. Furthermore, it suppressed MAPK pathway in OGD/R-induced neuron, thus protecting the neuronal cells from OGD/R-induced damage (p < 0.05).
Conclusion: Remimazolam protects neuronal cells from OGD/R-induced damage by mediating MAPK pathway. Therefore, it is a potential drug for the management of Ischemia-reperfusion injury (IRI). However, in vivo studies are required to buttress this.

Authors: Alahmadi Ahlam A. , Alahmadi Bassam A.
Published: September 2024

Purpose: To investigate the protective effect of ethanol extract of rosemary leaf (EERL) (Rosmarinus officinalis L., family Lamiaceae)  against testicular damage in streptozotocin (STZ) induced diabetes rats.
Methods: The study involved four groups of rats (n = 6). Type 2  Diabetes (T2D) was induced by injection of 50 mg/kg of STZ. Group 1 served as the control (non-diabetic) group. Group 2 included T2D rats without treatment. Group 3 comprised T2D rats treated with EERL at 200 mg/kg. Group 4 consisted of T2D rats treated with EERL at a  dose of 400 mg/kg. The extract was administered orally once a day for 4 weeks. Fasting blood glucose (FBG), serum testosterone, follicle- stimulating hormone (FSH) and luteinizing hormone (LH), and oxidative stress markers (superoxide dismutase (SOD), malondialdehyde (MDA), reduced glutathione (GSH), and glutathione peroxidase (GPx)) levels were assessed. Additionally, histopathological examination  using H & E staining and immunohistochemical analysis was conducted to evaluate the expression of proliferating cell nuclear antigen  (PCNA) and caspase-3 in the testes.
Results: Compared to the untreated T2D rats, EERL administration at 200 mg/kg and 400 mg/kg produced a significant decrease (p ˂ 0.05) in FBG levels and elevated levels of serum testosterone, FSH, and LH hormones (p ˂ 0.05).  Additionally, EERL administration (both doses) compared to the untreated T2D group led to a significant (p ˂ 0.05) reduction in testicular  MDA content and significant (p ˂ 0.05) enhancement of GSH, SOD, and GPx. Moreover, EERL exhibited potential inhibition of STZinduced  testicular damage and successfully averted apoptotic reactions by significantly reducing caspase-3 expression.
Conclusion: Ethanol  extract of rosemary leaf (EERL) diminishes testicular damage, and counteracts oxidative burden and apoptosis in T2D rats. Ethanol extract  from rosemary may be a source of molecules for development as a medicine to support sexual hormones in individuals with  diabetes.

Purpose: To investigate the effect of mecobalamin dispersible tablets and surgical treatment on nerve conduction velocity and skin  sympathetic reflex in patients with cervical spondylotic radiculopathy (CSR).
Methods: 82 patients diagnosed with CSR between February 2019 and January 2022 in Inner Mongolia Medical University School of Basic  Medicine, Hohhot City, China were randomized into control and study groups comprising 41 patients each. The control group was treated  with anterior cervical diskectomy and fusion, while the study group was treated with mecobalamin dispersible tablets in addition to surgery. Efficacy was assessed 3 months after surgery.
Results: Efficacy in the study group was significantly higher than in the control  group (p < 0.05). Furthermore, the study group had significantly greater motor and sensory nerve conduction velocity of the median and  ulnar nerve as well as reduced initial wave latency (p < 0.05). Scores of subjective symptoms, clinical signs, and life-work-social  adaptability were significantly higher in the study group than in the control group (p < 0.05). Range of motion of the neck significantly  improved and brainderived neurotrophic factor and glial neurotrophic factor were significantly increased in the study group compared to  control group (p < 0.05).
Conclusion: Mecobalamin dispersible tablets in combination with surgery improve nerve conduction velocity,  skin sympathetic reflex function, neurotrophic factor level, cervical motion, and cervical spine function in patients with CSR.  Multicenter long-term controlled studies with larger sample sizes are required in future studies.
Influence of Covid-19 restrictions on the status of mangrove vegetation in coastal Kenya

Published: September 2024

Mangrove forest ecosystems provide essential services to tropical coastal communities, includ- ing as a source of food, fuel and building materials. During the Covid-19 pandemic human movements were restricted at all levels, including locally in coastal communities. The impact of these measures on marine ecosystems such as mangroves were not well understood. A household survey was conducted in a mangrove-dependent community at Mtwapa Creek to evaluate their perceptions on the rate of mangrove degradation, factors contributing to man- grove degradation, and species that were most exploited during the pandemic period. Multiple Correspondence Analysis (MCA) was used to determine the association of Covid-19 with eco- nomic activities. Due to the restrictions on human interactions and travel during the pandemic, some natural ecosystems thrived, but in contrast accelerated destruction of mangrove forests occurred along Mtwapa Creek. The MCA indicated significant association between mangrove degradation rate and unemployment, charcoal burning, and reduced farming activities. A Chi- square test confirmed significant degradation of mangrove forests. Loss of income sources dur- ing the pandemic led to an increase in exploitation of Rhizophora mucronata, Ceriops tagal and Avicennia marina. These species were mainly harvested for construction and charcoal burning. Mangrove management measures could not be effectively enforced during the pandemic.

Published: September 2024

The study examined the knowledge, prevalence and prevention of dermatophyte infection among primary school pupils in Uyo metropolis. Four research questions were raised and the corresponding hypotheses were formulated to guide the study. A descriptive survey research design was used for the study. The population of this study consisted of 420 pupils from 20 selected primary schools. The selected schools were 5 schools each from the northern, eastern, southern, and western Uyo metropolis. The researcher developed an instrument titled ‘Knowledge-of-Infectious-Disease-Questionnaire’ for data collection. Face validity, content validity, construct validity, and reliability testing were used to validate the instrument. Simple percentage was used for answering research questions while Chi-square (X2) test was used for testing the hypotheses. An average of 61.59% of the pupils lacked knowledge of dermatophyte infection while 70.6% of them already had the infections indicating a lack of significant knowledge, but significant spread of dermatophyte infection respectively, among the pupils at p<0.05. Furthermore, an average of 52.2% of the pupils showed no significant knowledge of the causes, prevention and treatment of the infection, while 53.2% had their academic performances negatively affected due to the dermatophyte infection. Based on these findings, it was concluded that although there exists a high prevalence of dermatophyte infection among primary school pupils, knowledge, prevention and treatment is however low. Academic performance is also negatively impacted due to the infections. It is recommended that parents should keenly observe their wards for symptoms of these infections and promptly effect treatments to avoid disease spread onto classmates. Also, proper enlightenment of these children about dermatophyte infections should be done both by the parents and Government Health Workers.

Published: September 2024

Hepatitis E virus (HEV) is a pathogen that can be transmitted to humans through contaminated meat consumption, posing potential public health risks. This investigation aimed to assess the prevalence of HEV in meat and fecal samples from four animal species using anti-Hepatitis E Virus antibody [5F3] (ab233244) and Nested Reverse-Transcriptase Polymerase Chain Reaction (RT-PCR) techniques. Almost all samples (n = 44) exhibited significant HEV seroprevalence, with Swine Genotype 3/4 HEV detected in both pig meat and fecal samples. The use of Nested RT-PCR targeting the 3331N/3332N region identified this genotype in 6 pig samples, indicating a prevalence of 66.7%. No HEV was found using a universal nested RT-PCR assay on the primer region 3158/3159N, suggesting the presence of non-typical or novel HEV strains. This emphasizes the need for genotype-specific primers for thorough surveillance. These findings highlight the circulation of the specific genotype in the animal population, underscoring its potential as a source of HEV infections in humans. The positive immunological results in all 3 HEV-positive samples affirm the accuracy of the ELISA technique, crucial for viral diagnostics and surveillance. This study contributes valuable data on HEV prevalence in meat and fecal samples from diverse animal species, providing insights into the zoonotic risks associated with HEV through meat consumption or precooking exposure.
Application of the Langmuir and Freundlich equations for the removal of Cd2++ and Pb2+ ions by adsorption on to natural clay minerals

Published: September 2024

Metal ion sorption plays a critical role in mitigating environmental pollution. However, there is a dearth of research data on the sorption characteristics of Cd2+ and Pb2+ ions on natural clay minerals in Akwa Ibom State, Nigeria. This study aims to investigate the sorption behaviour of Cd2+ and Pb2+ ions on natural clay minerals using the Langmuir and Freundlich equations. Four samples of natural clay were collected from Ikot Ebom Itam, in Itu and were used for this study. Samples were characterized using standard analytical methods including X-ray fluorescence (XRF), X-ray diffraction (XRD) and Atomic Absorption Spectrophotometry (AAS). Results showed the elemental components to be more of silica and alumina as the predominant constituents, whereas EXRD analysis showed that the patterns of all four samples comprised predominantly crystalline phases of kaolinite (Al2Si2O5(OH)4), and quartz (Si6O6) except for sample CSA whose peaks were attributable to goethite (α-FeO(OH)). Results of metal analysis showed Cd, Pb and Fe concentrations (in ppm) ranged from 0.003-0.007, 1.04-1.76 and 0.54-13.54, respectively. The percentage composition of C, H, N and S ranged from 41 to 50%, 3 to 5%, 0 to 1% and 0 to 1% respectively. The EDXRF analysis shows that the clay minerals exhibited greater sorption capacities for Cd2+ and Pb2+ ions from aqueous solutions due to high levels of Fe and Al oxides. The Langmuir and Freundlich models were applied to study the sorption characteristics using Pearson correlation analysis. The Freundlich isotherm model offered the optimum option for Cd (R2 = 0.9548) sorption and Langmuir model for Pb (0.9940). Results shows that the sorption of these toxic metals on clay minerals which is dependent on pH, initial concentration of adsorbate and type of adsorbent can reduce their concentrations and mobility in aqueous solution and natural environment. Based on the study, it can be said that clay can be used as a less expensive and effective adsorbent in removal of Cd2+ and Pb2+ ions from aqueous solutions.

Published: September 2024

The increasing incidence of food shortages and nutritionally related diseases in the world has made it imperative to carry out nutritional studies on food materials. The proximate composition, minerals and vitamins, as well as the anti-nutrient constituents of the peels and flesh of sweet potato were determined. The peels were found to contain higher levels of crude protein (8.79 %), lipid (4.5 %), fibre (2.00 %) and ash (4.00 %) than the flesh (4.83 %, 0.1 %, 1.0 % and 3.0 % respectively) while the later had higher levels of moisture (71.29 %) and carbohydrate (91.07 %). The flesh was also higher in β-carotene (3.59 mg/100g) and vitamin A (4.30 IU) than the peels (1.26 mg/100g and 1.60 IU respectively), while the peels were higher in vitamin C (20.63 mg/100g). The peels were also found to contain higher levels of the minerals – iron (43.95 mg/100g), magnesium (20.63 mg/100g), manganese (0.07 mg/100g), calcium (40.41 mg/100g) and phosphorus (98.95 mg/100g) than the flesh (25.65 mg/100g, 2.11 mg/100g, 0.00 mg/100g, 16.84 mg/100g and 72.95 mg/100g respectively). The flesh had minimal levels of the anti-nutrient compounds - hydrocyanic acid (17.28 mg/100 g), tannins (385.19mg/100g), oxalate (total with soluble) (61.60 mg/100g) and phytate (557.26 mg/100g) while the peels showed higher levels of these compounds (21.60 mg/100g, 533.33 mg/100g, 433.60 mg/100g and 755.70 mg/100g respectively). Sweet potato tubers and peels are an excellent source of calories, vitamin C and beta carotene, with considerable amounts of protein and macro minerals. It is recommended that the peels of sweet potato be processed into animal feed and not discarded as garbage. Also, when properly processed to reduce anti-nutrient contents, the sweet potato peels can be consumed just as the flesh, thus can reduce malnutrition and other nutritional related diseases.

Published: September 2024

Seismic Reservoir Characterization is a pivotal element in seismic data interpretation. This study describes a successful utilization of model-based seismic inversion methodology coupled with Probabilistic Neural Network for the identification of hydrocarbon reservoir zones within post-stack seismic data. The paper unfolds in two segments. Initially, Acoustic Impedance (AI) volume is extrapolated from seismic datasets via the application of the model-based inversion algorithm in the time domain. The strong correlation coefficient of 0.988 between synthetic and seismic data underscores the effectiveness of model-based inversion. Subsequently, a Probabilistic Neural Network (PNN) undergoes training, validation, and testing utilizing estimated porosity data at well locations, serving as internal attributes, and the outcomes from model-based inversion as external attributes. The trained Probabilistic Neural Network is then deployed across the seismic volume to delineate a three-dimensional map in total porosity. A notable high value of total porosity, ranging from 16 to 30%, observed within horizons A and B, indicates a substantial volume of void spaces within the rock formation. Therefore, the presence of such elevated porosity values in horizons A and B signifies the existence of a promising reservoir with ample capacity for fluid storage and migration, which is scientifically significant for hydrocarbon exploration and production. The findings from this study underscore the potential of merging model-based inversion and PNN for effective estimation of reservoir properties, particularly in scenarios where the relationship between porosity and acoustic impedance exhibits non-linear characteristics

Loads and virulence of bacterial isolates associated with finfish, Caranx hullianus, from the estuarine water of Okwanobolo River in  Eastern Obolo, Niger Delta, Nigeria was investigated. The total heterotrophic bacterial count (THBC), total coliform count (TCC), faecal  coliform count (FCC), Salmonella-Shigella count (SSC), and Vibrio count (VC) of flesh, gills, and intestines of the fish samples were  determined using standard bacteriological methods. Virulence factors of the selected bacterial isolates were also determined using  microbiological techniques. The THBC and TCC of the flesh recorded mean log count of 5.12 CFU/g and 4.11 CFU/g respectively while FCC,  SSC, and VC were not detected. The intestines had the highest bacterial counts while the flesh had the least. The THBC, TCC, FCC and  SSC of the gills recorded mean values of 5.48 log CFU/g, 4.31 log CFU/g, 1.67 log CFU/g, and 1.82 log CFU/g respectively with no VC  detected. The THBC, TCC, FCC and SSC of the intestines recorded mean value of 5.61 log CFU/g, 4.42 log CFU/g, 4.31 log CFU/g, and 2.62  log CFU/g respectively with no VC detected. The analysis of variance revealed significant differences among the physiological groups in  the flesh (p = 1.36E 32 <0.05); gills (p = 7.18E-06 <0.05) and intestine (p = 1.67E-10 <0.05). Of the eight bacterial species associated with the  samples, Proteus sp. and Staphylococcus aureus were common in all the fish tissues. However, Escherichia coli, Streptococcus sp., Bacillus  subtilis, Klebsiella sp., Salmonella sp. and Shigella sp. were isolated only from the fish gills and intestines. These isolates exhibited varying  virulence potentials concerning DNase, Gelatinase, Lipase, Coagulase, and Urease markers. Staphylococcus aureus recorded the highest  occurrence (100%) for all the virulence markers while Escherichia coli, Klebsiella sp. and Shigella sp. recorded the least occurrence  (20%). Finfish from the estuarine environment habour potentially pathogenic microorganisms.

The healthcare system in Poland and in many other countries, is constantly changing. Often, these transformations are deliberate actions undertaken by the government, but sometimes those changes occur unintentionally. The functioning of a health care system remains a major concern of social life in our country. Whether it works well, depends on many factors that the authorities of the country have an impact on, to a greater or lesser extent. The aim of the article is to present the results of the 2018–2020 survey of nurses’ opinions on proposed changes to the health care system in Poland. The study was conducted during the years 2018–2020. The study group consisted of 100 people – all of them nurses. The research tool was an anonymous questionnaire consisting of open questions. Based on the research results, the following changes in the health care system were proposed: increasing the number of medical students, introducing official payments system for the patients, privatising health care facilities, creating competition among payers.

The subject of the analysis is the provisions of the Railway Transport Act concerning the use of passenger stations by railway undertakings and the making available of passenger stations to carriers by their operators. These provisions have given rise to doubts, in particular about determining which areas of passenger stations remain available to the carrier under rules appropriate to a service facility and whether the mere fact that the carrier’s trains stop at a given station obliges the carrier to conclude a contract with the station operator for access to the facility. In addition, the nature of the amendment made to the Act in this regard came into force on April 17, 2020, which has been divergently assessed in the case law as either a normative change or merely a clarification. The analysis furthermore touches upon the issue of the facility access agreement, which, according to the provisions of the Act, should be concluded between the operator and the carrier, and the possible grounds for the operator to demand fees for access to the facility in a situation where such an agreement has not been concluded.

The banking industry is the foundation of any nation’s economy, and bank deposits are its primary source of profitability. Bank deposits play a significant role in determining a nation’s saving rate. Globalization has resulted in substantial technological changes, business strategy, and customer service across many industries, including the financial services sector. This study proposes a deep learning model using Residual Network architectural design and transfer learning on a Portuguese banking institution containing 40,811 training data, with 36,202 belonging to label 0 and 4639 belonging to label 1. Clearly, this shows a significant level of bias between the two labels. Hence, a SMOTE method of class balancing was applied. This dataset, in comma-separated value (CSV), was converted into images coupled with the weight transfer from the residual network trained on ImageNet; our fully connected layer was built and trained with the image files. The highest performance reached by the conventional machine learning models, Random Forest (RF), is 90.78% for accuracy, 59.37% precision, 96.78% recall, and 85.28% F1 score, tested on 412 test samples. However, our proposed methodology achieves an outstanding result with an accuracy of 93.00%, 97.00% precision, 90.00% recall, 93.00% F1 score, and 94.00% ROC, with test samples of size 5601. Since long-term deposits are necessary for the banking system to fund the individual, corporate, and industrial loans needed for the country’s growth and development, these results will provide an effective and reliable marketing technique required to determine the target population.

Čačalica is a hill with the area of 26.6 hectars (203 m above the sea level) situated on the southeast outskirts of the city of Požarevac. Memorial Park Čačalica is a man-made „oasis of nature“ amidst the urban and agricultural surroundings, and it has been regarded as one of city’s icons for many years. Cultural and historical significance of this Memorial Park make its preservation imperative. This research presents the phytocenological assessment of section „V“, also known as the „Black pine section“, one of 24 forested sections in Čačalica. Based on the data obtained by the phytocenological evaluation in the spring of 2023, it was determined that in the Čačalica memorial park, in section „V“ of the area of 2.01 ha, 46 types of vascular plants were found within 25 families. The stand of three arbors was evaluated: first-order arboretums (tall trees), second-order arboretums (low trees and shrubs), third-order arboretums (herbaceous plants). One of the reasons why the inhabitants of Požarevac breathe the air of good quality safe for human health, despite well-developed industry and proximity of the the coal-fired power plant, is the existence and maintainance of green urban oases. The city of Požarevac has its own urban lungs.

The results of previously performed studies are summarized, and a methodology for estimating the lifetime consumption of fire tankers is presented. The proposed methodology takes into account the specific features of the practical operation of a fire truck, as well as its integral part — the tank, which has a significant impact on the loss of the lifetime of the vehicle as a whole. The methodology combines computational and statistical methods, and also develops an approach based on taking into account two interdependent factors: mileage and operating time. In combination, this makes it possible to differentially determine the lifetime consumption of fire tankers, taking into account the weighted average consumption of the lifetime potential of their main components. At the same time, to the known five typical groups of the main parts of the vehicle, which have a similar nature of lifetime loss depending on mileage (conditions, nature of loading and damage processes) and operating time, in the case of a tanker truck, it is proposed to add another characteristic group, tanks, using a dependence for assessing its lifetime, taking into account the lifetime consumption for corrosion wear. An example of calculating the lifetime consumption of a fire tanker is given. The results obtained show values corresponding to the actual processes of obsolescence. Scope of application of the results obtained is: assessment of the condition of a fire truck and its tank after long-term storage; extension of the operation of a fire tanker after the expiration of the established service life; extension of the service life after major repairs; extension of the service life after the main lifetime work out; decision on the expediency of repair or decommissioning of a tanker truck.

Ученый считал, что св. Сергий Радонежский знал о богословии св. Григория Паламы. В этом контексте публикуется письмо Топорова начинающему византинисту-паламоведу Д. И. Макарову от 2001 г., представляющее интерес для оценки состояния российской гуманитарной среды в конце ХХ — начале XXI вв.

Vladimir N. Toporov (1928–2005) in his Sanctity and the Saints in the Russian Spiritual Culture (1995–1998) has left us a lot of worthwhile observations, remarks, and considerations concerning the nature of sanctity (or holiness) which, among other things, do not contradict to the Palamite tradition. In Toporov’s mind, St. Sergius of Radonezh had known the theology of St. Gregory Palamas. In this context we publish Toporov’s 2001 letter to a beginning Palamite scholar Dmitry I. Makarov, which is of interest for a general appraisal of the conditions under which the Russian humanitarian milieu was working at the turn of the 21st century.

The basic human need for food is one of the factors that can support the growth of the culinary industry. Food presentation using a hotplate has become a trend that is very popular with the public in recent years. One of the hotplate business actors in Bandung Regency is Wisma Sukapura Hotplate, commonly known as WS Hotplate, which has a menu of chicken and beef steak dishes at affordable prices. WS Hotplate is in the campus area, especially Telkom University, so there is a decrease in income during the student holiday season. This study aims to determine in more detail the effect of promotion and physical evidence on purchasing decisions simultaneously and partially. This research uses quantitative methods and a series of tests such as the classical assumption test, which includes normality, multicollinearity, and homoscedasticity tests; multiple linear regression analysis tests; hypothesis testing, which provides for partial (t) and simultaneous (f) tests; and the coefficient of determination test. The non-probability sampling technique used is purposive sampling. The population of people domiciled in Bandung Regency who have purchased at WS Hotplate is unknown, with a sample of 100 respondents. Data testing in research using statistics, namely SPSS, shows that the results of this study are promotional variables and physical evidence that have a significant influence both partially and simultaneously on purchasing decisions at Wisma Sukapura Hotplate, Bandung Regency.

Oil & gas business is still attractive for investors. Today, they look carefully at company’s financial indicators (ROA, ROI, Profitability) and new indicator called “ESG” in making investment decision(Pedersen et al., 2021). PT.X, a developing national energy company with vision becoming world class, currently still rely on fossil energy as the backbone of its business. To finance its operations, PT.X opens up opportunities for investors to invest. To attract investors, PT.X is pursuing better ESG rating each year. In 2023 ESG score of PT. X is 20.7, 1st rank out of 61 O&G companies in the world (Morningstar Sustainalytics version). In competitive energy business post Covid-19 pandemic PT. X aware that they must improve its ESG score continuously. Several strategic goals have been set, one of it is Total Recordable Injury Rate / TRIR, a ratio of number of recordable incidents per total working hours in a year. Target is more challenging each year. TRIR 2024 was set 0.19. This number is much lower than the average TRIR achieved by IOGP members in 2020 that is 0.7. PT. X’s TRIR goal applies to all of its subsidiaries including PT. X-Y located in biggest O&G block East Kalimantan Indonesia. PT. X-Y operates big mature field ultimate with ultimate challenge to maintain oil and gas production from wells that decline naturally. PT. X-Y have planned massive work programs i.e: drilling ± 100 wells/year, ± 4000 wells intervention, and also several offshore platforms construction & installation projects. These activities involve many workers and very high risks. Workers’ safety culture is very important to support the achievement of this goal. Unfortunately, the results of surveys conducted several times by one of reputable university in Indonesia, PT. X-Y safety culture level has decreased from the Proactive to Calculative. To improve PT. X-Y should start by solving organization’s safety cultures’ issues. Also, with limited resources the company’s safety team believed they should focus on improving existing safety program called “TEMAN” rather than introducing new ones. OKR framework is used to manage these difficult objectives because it has superior principles and similarity with PT.X core value AKHLAK, i.e: align and connect team work, focus and commit to priorities, track for accountability. OKR method is successful helping big companies such as Intel, Google, IBM to achieve their stretch goals with minimal side effects / no side effects at all.
