Banana (Musa spp.) are giant perennial grasses, commonly known as ‘Apple of paradise’.The chromosome counting of Elachi, Poovan and Nendran Banana traits were recorded. In average, a number of chromosomes recorded in Poovan (13.2), followed by Elachi with 11.1 chromosomes and Nendran with 10.9 chromosomes. There are various methods of determining banana ploidy level, one among is estimating stomatal density and size. The present investigation Elachi, Nendran and Poovan stomatal density range from 50 to 55/mm2 which are diploid, while Robusta ranges 34/mm2 which is triploid. Highest stomatal size recorded in Poovan traits (48 μm2) followed by Robusta (45 μm2), Nendran (28 μm2) and Elachi (21 μm2). Another method of ploidy determination is by chloroplast count in a guard cell of stomata. Elachi, Nendran, and Poovan contain 8 chloroplasts in the guard cell thus belongs to diploid. In the analysis of floral characters of all the four traits reveals that there is no significant difference in stigma length and width. Similarly, no significant variation recorded in anther length. Pollen size is often used as a biological parameter to estimate the ploidy and viability of mature pollen grains. Broad variation in pollen viability exists among clones with Musa species. Mycorrhizal association with the higher plants has also shown an increase in agricultural productivity. The percent colonization of AMF with the root system was calculated by two methods. Compare to Method – I and Method – II reveals that in Elachi 2.5%, Poovan 13.3% and 17.5% of variations recorded. Overall in the average highest percent of colonization were recorded in Poovan (76.6%).

Automated result management system for students results processing

This study was carried out to verify all the manual process involved in generating Students Examination Result and to seek a way of automating the system for effective operations. Computer and its appreciations have become vital tools in the economic, industrial and social development of advanced countries of the world. Most educational institutions in Nigeria, such as Universities, Polytechnics and Colleges of Education still operate on the manual method of record keeping and computation of students’ grade point averages (GPA) which is time-consuming and error-prone especially when the number of students is large. This paper examines the inadequacies involved in the manual method of calculating Students CGPA (cumulative grade point average) and proposes a solution by developing a software application to facilitate the automated processing of the results. The software was developed using the Microsoft Excel spreadsheet program. The developed software was tested and found to performed well and produced expected results on completion. With it, it was possible to compute Grade Point Average (GPA) and Cumulative Grade Point Average (CGPA) for each student based on examination scores entered. The new system has some qualities such as reduction in the cost of processing of information, reduction in time spent in computing GPA and generating transcripts, increase in accuracy and efficiency, and elimination of duplication of effort which makes it superior to the manual system of student record keeping. This new system is flexible and can be modified to suit any kind of student’s record-keeping and data processing.

Management of solid healthcare wastes in some government healthcare facilities in enugu state, southeast nigeria: a cross-sectional study

Background: The significance of healthcare wastes (HCWs) consists in their hazardous component, which constitutes real danger to public health. In Nigeria, healthcare waste management (HCWM) has remained a problem yet to be properly recognized and so addressed. The study aimed to sensitise health workers and the public on the need for proper management of HCWs, considering the public health implications of not doing so. Methods: The waste management systems of ten healthcare facilities (HCFs) were assessed, using a modification of the WHO rapid assessment tool. In each HCF, segregated wastes were collected daily for ten days and quantified by weighing, using a spring balance. Results: Administratively, the HCWM system was poor in the ten HCFs (40.6%). 70% of them had satisfactory waste segregation, 81%, good waste treatment, and 26.7% adequate transportation methods for waste. None of the HCFs had budget allocation for HCWM, and 90% had inadequate storage facilities. Mean waste generation was 1.81 kg/day, 0.23 kg/patient/day, 0.16 kg/bed/day, and proportion of infectious wastes 16.8%. Correlation between the number of patients and proportion of infectious waste, was positive, strong and significant (r=0.80, p=0.01), and between bed occupancy rate and proportion of infectious waste, was positive too, but weak, and insignificant (r=0.34, p=0.34). Conclusions: In view of the identified weaknesses of the ten HCFs in HCWM, budget allocations for HCWM, improving waste storage facilities and transportation, with strengthening of waste segregation, collection, and treatment, would help to ensure adequate HCWM in the HCFs.

Metronidazole-induced neurotoxicity: is iron a contributing factor?

Metronidazole-induced neurotoxicity is a rising challenge in managing susceptible infections. The mechanisms involved in metronidazole-induced neurotoxicity are not fully unraveled. This study aimed to explore the effect of metronidazole on iron homeostasis in SH-SY5Y neuroblastoma cells. Confluent SH-SY5Y neuroblastoma cells were treated with different concentrations of 1.0, 10, 25, 50, 100, and 250 µM of metronidazole only or in combination with 20 µM iron. DMSO or culture media was used as control. Viability and ferritin assays were conducted on the treated cells. The treatments were for 24 hours, 48 hours, and 72 hours, respectively. In the viability assay, doses of metronidazole reduced the viability of SH-SY5Y neuroblastoma cells in a time and concentration-dependent manner. After 24-hour treatment, 250 µM metronidazole significantly reduced cell viability while 50 µM, 100 µM and 250 µM metronidazole reduced considerably viability only after 48-hour and 72-hour compared with control. Different doses of metronidazole 50 µM, 100 µM, and 250 µM in 20 µM iron reduced viability in a time-dependent manner in all the test periods. Metronidazole also induced a time- and concentration-dependent increase (p<0.05) in cellular iron uptake in the 48-hour and 72-hour treated cells in concentrations above 25 µM metronidazole. It is concluded that metronidazole induces a time and concentration-dependent iron overload and consequent cell death in SH-SY5Y neuroblastoma cells and this may contribute to the mechanism of metronidazole-induced neurotoxicity.

Probing the filipino college students' pragmatic competence: its pedagogical implications in language teaching and learning

The study identified the pragmatic competence level of the second language (L2) learners through Written Discourse Completion Test (WDCT) administered to purposively selected 40 first-year education students. A modified questionnaire based on Survey for Academic English Language Exposure (SAELE) was used to determine the effectiveness of academic English language exposure on the pragmatic competence development of the respondents. The study employed the descriptive-correlational method, while various statistical tools were utilized to analyze and interpret the data. Weighted mean was used to determine the respondents’ pragmatic competence level and the effectiveness of academic English language exposure on the pragmatic competence development of the respondents. Moreover, Pearson Product Moment Correlation (PPMC) was employed to determine the significant relationship between the two variables. Results in WDCT showed that the average scores in the pre-test and post-test results fall under the competent level. Meanwhile, the effectiveness of academic English language exposure on the pragmatic competence development of the respondents was 0.207, which is ineffective. Lastly, the statistical correlation of the two variables showed no significant relationship between them (r=0.046, p>0.05). Based on the study’s results, pedagogical implications for pragmatic and L2 teaching and learning were conceptualized.

Screening of pigeonpea varieties through nylon bag no-choice bioassay for host plant resistance to helicoverpa armigera

Background: The legume pod borer, Helicoverpa armigera (Hübner), is one of the most damaging crop pests, including pigeonpea. Host plant resistance is a component of pest management and therefore, we standardize a nylon bag No-Choice Bioassay technique to screen for resistance to H. armigera under field conditions. Methods: Pigeonpea plants were infested with 24 h old 1, 2, 3, 4 and 5 larvae per plant inside the nylon bag. Observations were recorded on pod damage, larval survival, larval weight, pupation, adult emergence, and fecundity after 10 days. Result: Pigeonpea varieties AL-201, H03-41 and PAU-881 exhibited lower pod damage (15.89 to 19.77%) and larval weight (12.02 to 13.82 mg). The expression of resistance to H. armigera was associated with trichome density, pod wall thickness and higher amount of phenolic compounds and condensed tannins. Lower trichome density and thin pod walls and higher amounts of sugars rendered the varieties Paras, Manak and Pussa-992 more susceptible to H. armigera. Nylon bag assay can be used to screen and select pigeonpea cultivars for resistance to H. armigera.

Analyzing game strategies of the don’t get angry board game using computer simulations

In the research described in this paper, we used computer simulations to analyze and compare different types of game strategies in the popular board game Don't Get Angry. Following a brief introduction, we summarized a few previous research papers examining similar board games' game strategies. Next, after a review of the Don't Get Angry game's official rules, we outlined four strategies that can be applied to increase the likelihood of winning. We simulated 50,000 games in which all four players made their moves randomly and 50,000 games where each used a different strategy. We tracked how frequently each player finished first, second, third, or last during the simulations. Furthermore, we recorded how many rounds were needed to complete the game for each player, how many times the players’ pawns were kicked out and returned to their houses by other players, and the number of players’ remaining steps during every gameplay. From the analysis of the recorded data, we could conclude that significant differences exist in the chances of winning the game for the examined strategies when all players use different strategies. The results improve the specific domain knowledge for the Don't Get Angry board game. It may help create more vigorous computer opponents and encourage further study to create a tool for evaluating students' strategic thinking while playing.

Effects of hypersaline conditions on the growth and survival of larval red drum-(sciaenops ocellatus)

Texas bays and estuaries experience salinity fluctuations (e.g., droughts, reduced freshwater inflows and hurricanes) caused by natural weather and climate change. This could have impacts on red drum Sciaenops ocellatus (Linnaeus) early life stages beacause red drum spend their early life stage at the shallow bays and estuarine waters of Texas Bay. The purpose of the present study is to evaluate the impact of high salinity concentrations on the survival, growth and development of red drum eggs and larvae. Red drum brood stocks were collected from wild stocks throughout the lower Texas coast and were held in hatchery tanks (13,250 L) until spawning. The water quality conditions were maintained at a salinity of 38ppt and seawater temperature of 25°C. The red drum eggs were hatched at a wide range of salinity treatments (28-48ppt). Egg hatch-out rates and larvae growth were reduced at the lowest (28ppt) and highest (48ppt) salinity treatments. Hypersalinity (≥ 40ppt) and a temperature of 25ºC affected the hatching success of red drum eggs. The percentage of egg hatching success and length of larvae were reduced in both lower (28ppt) and/or hypersalinity (48ppt). This study shows that red drum eggs can hatch within a wide range of salinities with best hatch-out and growth rates occurring between 33 – 43ppt. It also suggests that climate change that produces global warming can keep the increasing environmental salinity of the Texas bay which might have an impact on the development of the early stages of the red drum in their natural environment.

P2pcpm: point to point critical path monitoring based denial of service attack detection for vehicular communication network resource management

Various types of security attacks are normal in vehicular communication networks. The current study uses a support vector machine to implement a Point to Point Critical Path Monitoring (P2PCPM) based Denial of Service (DOS) Attack detection technique for Vehicular Communication Network (VCN) resource management. Greatest quality of P2PCPM is that it eliminates attacked nodes from the network for the smooth process of vehicular communication. This scheme works well in terms of accuracy as well as attack detection rate. The whole simulation is made and tried by utilizing MATLAB Software. Simulation result shows 99% accuracy in case of security attack detection as well as reduced training and testing error upto 2%. Experimental results indicate that this scheme has a great efficiency and works well up to 1000 nodes, which is the limitation of current implementation. In future, simulation test may be done for unlimited nodes using similar or other techniques of attack detection.

Effects of rapeseed oil (rapus indicus) supplementation on omega-3 fatty acid concentration and carcass characteristics in broiler chicken

Dietary fatty acid composition in broiler influences carcass quality by altering fat deposition and fatty acid profile. Thus, the study was carried out to evaluate the effect of incorporation of rapeseed oil in broiler ration on omega-3 fatty acid concentration of carcass and its traits in broiler chicken. A total of 160 day-old straight run broilers (Vencobb 400) were randomly divided into four treatment groups (G1, G2, G3 and G4) having four replicates of ten chicks each. The basal diets (G1) were prepared to meet BIS (2007) nutrient requirements with palm oil at 1.5, 3, and 4.5 per cent in pre-starter, starter and finisher diets, respectively. The experimental diets were broiler rations prepared with rapeseed oil replacing 25, 50 and 100 per cent of palm oil in G2, G3 and G4 diets, respectively. The diets were fed ad libitum till 6 weeks of age. Six birds from each group were randomly selected and slaughtered on 42nd day to study omega-3 fatty acid concentration of carcass and its characteristics. The crude fat content of breast and thigh muscle was significantly (P<0.05) reduced in the group fed rapeseed oil included diets. However, carcass yield, processing yield and meat to bone ratio of cut up parts was not significantly affected. The colour and pH of breast and thigh muscles were similar among the treatment groups. Omega- 3 fatty acid concentration was significantly (P<0.01) increased in both breast and thigh muscle of G4 group broilers compared to G1 group. Thus, rapeseed oil inclusion in diet significantly increased omega-3 fatty acid concentration and significantly reduced crude fat concentration breast and thigh muscles with no effect on the carcass yield and its quality when included in the diet replacing palm oil at different proportion

Metformin dosage and renal protection in type 2 diabetes mellitus: impact on estimated glomerular filtration rate

Metformin is considered the first-line treatment as a monotherapy for patients with type 2 diabetes mellitus. Emerging evidence suggests that metformin may have a renoprotective role; therefore, understanding the impact of metformin dose and therapy duration on renal function may significantly improve renal outcomes in type 2 diabetes patients. This study aims to investigate the renoprotective effects of metformin by analyzing its dose-dependent impacts on the estimated glomerular filtration rate in patients with type 2 diabetes mellitus. A retrospective cross-sectional study design was used from September 2022 to October 2023. Data from 302 type 2 diabetes patients were collected from patient files at the Benghazi Diabetic Center and the Aljabal Al-Alkdar Diabetic Center, including all with type 2 diabetes mellitus patients on varying doses of metformin. The collected data included age, gender, metformin dose, duration of metformin therapy, urea, and creatinine. Exclusion criteria included patients with significant comorbidities such as chronic kidney disease (other than diabetic nephropathy), liver disease, heart failure, or malignancy; those taking nephrotoxic medications; individuals with recent acute illnesses or surgical procedures; pregnant or lactating women; participants with inadequate medical records; and patients who were non-adherent to metformin therapy. Survival analysis was conducted to evaluate the effect of different metformin doses on the estimated glomerular filtration rate. The study analyzed 302 diabetic patients, of whom 46.0% were male and 54.0% were female. The age was 58.3±11.9 years. The HbA1c was 7.7%±1.3%. The duration of diabetes was 11.4±8.1 years. The creatinine was 1.0±0.9 mg/dL, and the urea was 36.7±23.8 mg/dL. Data analysis revealed a statistically significant difference in survival distribution across the dose groups. Different metformin doses significantly impact the estimated glomerular filtration rate, suggesting that dosage plays a crucial role in maintaining renal function.

Determinants of intention to improve oral hygiene behavior among students based on the theory of planned behavior: a structural equation modelling analysis

Introduction: The prevalence of oral hygiene behaviors (OHB) is very low among school children in Ethiopia. However, the determinants of student's readiness/intention to perform those behaviors have been remained unstudied. Objective: This study aimed to identify the determinants of oral hygiene behavioral intention (OHBI) among preparatory school students based on the theory of planned behavior (TPB). Methods and materials: An institution-based cross-sectional study was conducted among 393 students. A 98-item self-administered questionnaire was used to evaluate oral hygiene knowledge (OHK), oral hygiene behavior (OHB), and OHBI based on TPB variables [attitude (ATT), subjective norms (SN) and perceived behavioral control (PBC)]. Descriptive statistics and structural equation modeling analysis (SEM) were employed to confirm relationships and associations among study variables. A p-value of less than 0.05 and a 95% confidence interval were used to declare statistical significance. Results: A total of 393 students were participated with a response rate of 97.5%. The mean age of the participants (54% females) was 18 (± 1.3) with an age range of 16 to 24. The TPB model was well fitted to the data and explained 66% of the variance in intention. ATT (β = 0.38; 95% CI, (0.21, 0.64)), SN (β = 0.33; 95% CI, (0.05, 0.83)) and PBC (β = 0.29; 95% CI, (0.13, 0.64)) were significant predictors of OHBI, where ATT was the strongest predictor of OHBI. Conclusion: The TPB model explained a large variance in the intention of students to improve their OHB. All TPB variables were significantly and positively linked to stronger intent, as the theory suggests. Furthermore, these results suggest that the model could provide a framework for oral hygiene promotion interventions in the study area. Indeed, these interventions should focus on changing the attitudes of students towards OHB, creation of positive social pressure, and enabling students to control OHB barriers.

Incidence of gestational hypertension among pregnant women (2006-2015) in enugu state, southeast nigeria: a retrospective study

Background: Gestational hypertension (GHTN) is defined as a new rise in blood pressure (BP) ≥140/90 mm Hg, presenting at 20 weeks gestation without significant proteinuria. Worldwide, 4.4%-15% of all pregnancies are complicated by HTN. The aim of this study was to determine the incidence of GHTN among pregnant women in Enugu State, Southeast Nigeria with a view to improving and strengthening antenatal services in the State to help reduce the proportion of maternal mortality and fetal outcomes attributable to GHTN and reduce the overall prevalence of HTN in the country. Methods: Records of BP, biodata and laboratory investigations (urinalysis, full blood count) of women who attended antenatal clinics in six selected state hospitals (2006-2015) were examined. Data were analyzed as proportions, t-test, ANOVA and Pearson product moment correlations using Maxstat (version 3.60) statistical software. Results: The overall incidence of GHTN was 5.9% with annual fluctuations with peaks in 2010 and 2014. There were significant differences in incidence among the age groups (<20>35 years) (p<0 p=0.0016).>35 years) and GHTN (r=0.932, p=0.0069). Between parity and GHTN, there was also positive, strong and significant correlation (r=0.813, p=0.0491). Conclusions: With an incidence of GHTN at 5.9%, there is need to improve and sustain adequate antenatal services in order to help reduce the proportion of the country’s maternal mortality attributable to hypertensive disorders of pregnancy.
