Evaluation model of english teaching effect based on neural network algorithm and support vector machine

Abstract- The role of support vector machine in the evaluation of English teaching effect is very important, but there is a problem of inaccurate evaluation of results. The traditional English teaching mode cannot solve the accuracy and efficiency of the effect evaluation of students' English teaching and cannot meet the requirements of English teaching effect evaluation. Therefore, this paper proposes a neural network algorithm to innovate and optimize the analysis of support vector machines. Firstly, the relevant theories are used to construct a multi-index English teaching effect evaluation system with teachers and students as the main body, and the indicators are divided according to the data requirements of English teaching effect evaluation indicators to reduce the support vector machine in the interfering factor. Then, the neural network algorithm is used to solve the optimal solution of kernel function parameters and regularization parameters of the support vector machine, and the support vector machine scheme is formed, and the support vector machine results are carried out Comprehensive analysis. MATLAB simulation shows that the evaluation accuracy of the English teaching effect of the neural network algorithm and the support vector machine under certain evaluation criteria Optimal, short evaluation time.

Analysis of association of vitamin d3, hemoglobin and ferritin with special respect to libyan patients

Anemia, iron deficiency and iron deficiency anemia are common blood disorders. The role of vitamin D was agreed to be regulating in calcium and phosphate absorption and bone metabolism and its deficiency is observed as a crucial nutritional problem. Vitamin D is created under the skin by ultraviolet light. It is usually get vitamins from the food; however, in the case of vitamin D, there simply are not enough rich food sources for people to get adequate amounts in their diet. Its effects on the prevention of diseases such as cardiovascular disease and anemia has received much attention recently. To get sufficient vitamin D, need to be exposed to sunshine or use supplements. Vitamin D3 was found in the largest population as a deficiency. With regard to hemoglobin was the subject whom has less normal range of hemoglobin (19.05%) than international normal range, and in ferritin the low population number was the subject whom has less normal range of ferritin than WHO normal range. The population who has low ferritin also has low vitamin D3 and variable hemoglobin. According international guidelines, optimizing nutrition with daily or intermittent (1 to 3 times per week) iron supplementation, should be considered a first-line intervention in high-risk or high-prevalence groups. Although it is probably less effective than daily iron supplementation, intermittent iron appears to be a useful and cost effective way of controlling anemia and iron deficiency anemia. This may indicate that a positive relation between the low concentration parameter of vitamin D3 and ferritin level but no significant correlation with hemoglobin.

Using common medicinal plants to treat high blood pressure: an updated overview and emphasis on antihypertensive phytochemicals

The primary cause of many fatalities is hypertension (high blood pressure). Many hypertensive patients are not even aware that they have the condition. As a result, hypertension is sometimes referred to as a silent killer. Until the harmful effects of high blood pressure, such as myocardial infarction, stroke, renal abnormalities, and vision problems, are identified, hypertension is typically asymptomatic. Without the use of herbs and dietary control, conventional medication therapy could not be enough to treat hypertension. The growing number of persons with high blood pressure can be effectively treated using alternative medicine. Numerous alternative therapies, such as diet, exercise, stress management, vitamins, and herbs, have been proven to be effective in lowering high blood pressure. There are several medications available to treat this disorder however popular antihypertensive medications typically have a long list of adverse effects. Numerous active ingredients with pharmacological and preventative qualities found in medicinal plants can be used to treat hypertension. This review discusses an overview of important medicinal plants and phytochemicals with hypotensive or antihypertensive effects.

Seroprevalence of avian leukosis virus in local chickens in five live bird markets, kaduna metropolis, north-western nigeria

Avian leukosis virus is recognized as an important viral pathogen in the poultry industry, resulting in salient severe economic losses due to reduced production, uneven flock growth rates, reduced growth, and immunosuppression which predispose affected birds to other infections. This study examined the seroprevalence of avian leukosis virus (ALV) in local chickens (LC) in 5 different live bird markets (LBMs) in Kaduna Metropolis. A total of 276 sera were tested for ALV p27 antigen using enzyme-linked immunosorbent assay (ELISA). An overall seroprevalence of 28.3% (78/276) was recorded in the study. At the market level, the seroprevalence of 35% (21/60), 30% (18/60), 32% (16/50), 28.6% (16/56), and 14% (7/50) were recorded for Sabon Tasha, Central market, Railway station, Kawo and Sokoto Road LBMs respectively. With regards to sex, female LC showed a significantly higher prevalence of 30.5% (46/105) compared to male chickens 26.9% (46/171) with no significant difference (P > 0.05) observed. This study established the presence of antigen to ALV in local chickens sold in LBMs. We recommend surveillance and further studies on the isolation, molecular characterization and pathogenicity of ALV in the study area.

Acute and sub-acute toxicity studies of the methanol extract of oecophylla longinoda by oral administration in rats

Oecophylla longinoda has some reported medicinal uses, including antimicrobial, analgesic, and anti-inflammatory activities. This study was designed to investigate the Oecophylla longinoda methanol extract to evaluate the toxicity profiles of its acute and sub-acute effects. The experiments were conducted to determine the oral median lethal dose (LD50) and other gross toxicological manifestations on an acute basis. In the first phase of the acute toxicity study, three per group were administered Oecophylla longinoda at single oral doses of 10, 100, and 1000 mg/kg body weight, and 1600, 2900, and 5000 mg/kg of Oecophylla longinoda in the second phase. In the sub-acute studies, the mice were orally administered 2.5 g/kg Oecophylla longinoda per day for 14 consecutive days. Rat body weight and fluid intake were recorded during the 14 days. The rat kidney, heart, liver, and blood sera were obtained for weight, histological, and biochemical markers including glucose, cholesterol, proteins, triglycerides, enzymes including ALT, AST, and ALP, as well as electrolytes (sodium and potassium) examinations. Results show that the methanol extract of Oecophylla longinoda is safe, and no significant changes in the biochemical markers that indicate harmful effects on the kidney and liver were observed in mice. However, the liver showed slight changes while the kidneys and heart remained healthy in mice exposed to Oecophylla longinoda. The no-observed-adverse-effect limit was 5000 mg/Kg body weight/day.

Design and analysis of a scooping engine valve

Inlet valve in an engine tends to be subjected to immense thermal loads besides chemical corrosion. Opening and closing of inlet valve practically could be in the order of 2000 times per 1.6 km. In the mean time of engine working cycle, seat insert of the inlet valve is the surface, against which an intake valve seats. Conventional engine valves are provided with a curved angle for its seating position, but for this study, the same is proposed to be positioned at a tapered angle. This tapered position as converted into radius in order to permit rich air at the inlet and reduce exhaust emission. This study is to investigate the nature of the future redesigned Scooping valve for a 1.25L 4-cylinder Petrol engine with VTVT (Variable Timing and Valve Train) under combined mechanical and thermal loading cycle by feeding the input conditions for this study after NX-CAD modelling in ANSYS 10.0 software and the numerical results thus obtained are recorded for future valve design considerations.

Metformin – a new frontier in skin cancer pharmacotherapy

Metformin, a widely prescribed biguanide for type 2 diabetes, has emerged as a promising candidate in skin cancer therapy due to its diverse anticancer mechanisms. Beyond its glucoselowering effects, metformin inhibits key oncogenic pathways, including the PI3K/AKT/mTOR and insulin/IGF-1 signaling pathways, activates AMP-activated protein kinase, and disrupts mitochondrial complex I function. These mechanisms are presumed to contribute to metformin's antiproliferative, pro-apoptotic, and anti-inflammatory effects, potentially reducing tumor growth and metastasis in melanoma and non-melanoma skin cancers. Predictive molecular docking studies reveal that metformin interacts with critical proteins in melanoma pathophysiology. Against PI3K/mTOR (PDB: 5OQ4), PTPN2 (PDB: 7UAD), and TRIP13 (PDB: 5VQA), metformin exhibited docking scores of -4.4, -4.6, and -5.6 kcal/mol, respectively, interacting via hydrogen bonding with residues such as ASP-836, ASP-964 (5OQ4), ASP-50 (7UAD), and SER-187, SER-138 (5VQA). Compared to standard inhibitors, PQR309 (-9.4 kcal/mol), ABBV-CLS-484 (-7.5 kcal/mol), and ATP (-10.8 kcal/mol), metformin displayed moderate binding affinity, suggesting potential but weaker inhibition of these targets. Preclinical and clinical studies support metformin's potential to reduce skin cancer risk, particularly in diabetic patients. However, challenges regarding bioavailability, optimal dosing, and patient selection persist, necessitating further investigation. Therefore, given its affordability, safety, and multitargeted action, metformin represents an attractive candidate for repurposing in skin cancer pharmacotherapy. Focusing future research on optimizing its therapeutic application, refining drug combinations, and identifying biomarkers would enhance clinical outcomes.

Research capability of teachers: its correlates, determinants and implications for continuing professional development

Recently, research capability has received an overwhelming and remarkable interest among academics and practitioners. This is timely since the Department of Education had institutionalized research and encouraged teachers to engage in it to support evidence-based practice, decision-making, policy, and program development. On these premises, a study was carried out to assess the research capability of public teachers in Malaybalay City, determine its correlates and determinants. It utilized descriptive, correlational, and explanatory designs. It administered survey questionnaires to 92 participants. Data were analyzed using descriptive and inferential statistics. The results revealed that teachers were slightly capable of conducting research and having neutral attitudes toward it, motivated to write research, had a high level of difficulties in research processes, and moderately capable of action planning. They also show evidence of potential in mentoring. Further, mentoring and action planning skills, motivation to write research, attitudes toward research, and the number of studies completed by teachers were the correlates of their research capability at different magnitudes of the relationship. Notably, the research capability of teachers had a low, negative but significant relationship with their age and accumulated years of service. Thus, this capability deteriorates as they age and accumulate years of service. The motivation to write research, the number of studies completed, and age were the determinants of research capability. It was concluded that research capability can be determined and predicted by how motivated teachers are to write research, how productive they are in research, and how young they are when they engage in this rigorous endeavor. The study identified and recommended topics for continuing professional development.

The silent scream of skin cells: a brief review of slow electrical signaling in the epithelium

Epithelial cells, lining the skin and internal organs, play a crucial role as protective barriers and regulators of substance transport. Traditionally, these cells were not considered to employ electrical signaling for communication. However, recent investigations have unveiled that epithelial cells generate slow electrical signals, termed the "silent scream," in response to injury, thus challenging conventional views of intercellular communication. A recent experimental investigation provided compelling evidence for this phenomenon, demonstrating the ability of these cells to transmit electrical signals over considerable distances within the epithelium. The research utilized microelectrode array chips to precisely detect subtle electrical events in keratinocytes and Madin-Darby Canine Kidney (MDCK) cells, revealing spiking activity characterized by slow propagation speeds, distinct from the rapid action potentials of neurons. The mechanisms underlying this novel signaling are explored, focusing on the involvement of mechanosensitive ion channels, calcium signaling, and Adenosine triphosphate (ATP) release. Calcium ions, well-established intracellular messengers, appear to play a central role in this biological phenomenon. Integrating this newly discovered communication mode into the existing understanding of skin cell biology reveals a more intricate picture of how skin senses and responds to its environment. The implications of this finding extend to various facets of skin physiology and pathology, including wound healing, inflammation, and skin aging. In wound healing, where endogenous electric fields guide cell migration and promote repair, this unique type of electrical signaling potentially plays a crucial part. Furthermore, aberrant electrical signaling might contribute to chronic inflammatory conditions, and age-related changes in this signaling could underlie the functional decline observed in aged skin. The potential for other environmental stressors to trigger the epithelial-generated electric signals also warrants investigation. The exploration concludes by discussing potential technological applications, such as bioelectric sensors and enhanced wound healing therapies, and future research directions aimed at further elucidating the molecular mechanisms and functional roles of this non-excitable cell electrophysiology.

Hypotensive activity of melilotus officinalis (l.) pallas

Melilotus officinalis (L.) Pallas. is used traditionally to treat hypertension and chronic venous insufficiency. The high prevalence of hypertension and the side effects of antihypertensive drugs potentiate us to evaluate Melilotus officinalis. The hypotensive effect of Melilotus officinalis butanol fraction (MOBF) was investigated in anaesthetised normotensive rats. The doses of 60, 80 and 100 mg/ kg, i.v., produced a significant (P<0.05) decrease in blood pressure. The statistically non-significant reduction in blood pressure was shown by 20 and 40 mg/ kg, i.v. These results suggest that Melilotus officinalis exhibited a hypotensive effect in normotensive rats. However, further evaluation of compound-related activity is required.

Incidental discovery of a developmental venous anomaly: a case report of a 37-year-old female with chronic headaches

Developmental venous anomalies (DVAs) are congenital vascular malformations often found incidentally on neuroimaging. This case report describes a 37-year-old female with chronic headaches and an incidentally discovered DVA in the left frontal lobe. Magnetic resonance imaging (MRI) revealed a classic "caput medusae" pattern without hemorrhage or associated cavernous malformation. This case highlights the importance of recognizing DVAs as incidental findings, differentiating them from other causes of chronic headaches, and understanding the significance of associated imaging findings.

Spinal brucellosis without apparent risk factors: a case-based diagnostic approach and literature review

Brucellosis is a zoonotic infection often linked to direct or indirect exposure to animals or unpasteurized dairy products. Atypical presentations in patients without classical risk factors pose significant diagnostic and management challenges. A 68-year-old woman presented with a 2-month history of burning pain involving cervical and lumbar regions, associated with weight loss, decreased appetite, and subjective fever. Examination revealed paravertebral tenderness and left knee swelling with effusion. Previous MRI showed multifocal marrow edema and soft tissue thickening in the lumbar spine, suggesting infection or inflammation. The patient denies exposure to unpasteurized dairy products, raw meat, or animals. Brucella serology revealed positive IgG with Brucella melitensis titer 1:160, later confirmed by blood cultures. PET imaging demonstrated multifocal metabolically active arthritic changes involving the spine, shoulders, and knees. Arthrocentesis confirmed inflammatory arthritis due to brucellosis. The patient was started on doxycycline, rifampin, and a 14-day course of intravenous gentamicin. During hospitalization, management was complicated by persistent knee pain and swelling requiring multimodal analgesia. Spinal brucellosis in the absence of classical risk factors is an odd presentation, emphasizing the importance of maintaining a high index of suspicion in endemic regions. Advanced imaging and microbiological confirmation are pivotal procedures in diagnosis. Early recognition of atypical brucellosis is critical to prevent complications and improve outcomes.

Enhancing thermal comfort and indoor air quality through energy optimization with neural network

Indoor thermal comfort and air quality are essential for occupant well-being, while simultaneously optimizing energy consumption in buildings. Achieving a balance between these factors presents a significant challenge, as indoor environments are dynamic and energy demands fluctuate. By modifying ventilation rates in response to real-time data, demand-controlled ventilation systems can reduce energy consumption and enhance indoor comfort and air quality. However, optimizing these systems with advanced predictive models remains a complex task. To address this challenge, this publication proposes a Dual-Stream Multi-Dependency Graph Neural Network (DMGNN)-based energy-efficient ventilation management technique that maximizes indoor air quality and thermal comfort. The suggested method seeks to enhance thermal comfort and air quality by maximizing heating, ventilation, and air conditioning (HVAC) operations while reducing energy consumption. Initially data are collected from an Indoor Air Quality Monitoring Dataset. The DMGNN is employed to capture the complex dependencies between environmental factors such as temperature, humidity, and CO2 concentrations, considering both temporal and spatial relationships. Implementing the proposed system and evaluating it through simulations in various building environments demonstrates notable improvements in thermal comfort, indoor air quality, and energy economy. The suggested system’s performance is contrasted with that of other current methods, showing superior energy efficiency and optimization of both indoor air quality and occupant comfort. This study presents an innovative, scalable framework for smart building management, promoting sustainable energy solutions.

Role of pharmacy students in fostering rational use of dietary supplements: knowledge, attitude, and practice study

Dietary supplements are extensively consumed, but irrational use is a health hazard. Pharmacy students, being future healthcare providers, can facilitate rational use. The present study evaluated the knowledge, attitudes, and practices of pharmacy students at Srinivas College of Pharmacy, Mangalore, about dietary supplements and their role as an advocate, in addition to mental health correlations. 250 students selected through stratified random sampling took part in a cross-sectional mixed-methods study. A 30-question instrument (Cronbach's alpha=0.85) measured demographics, dietary supplement usage, knowledge, attitude, practices, and mental health was evaluated with the depression, anxiety, and stress Scale-21 (DASS-21). The data were collected during January-March 2025 and were analyzed with the chi-square test, logistic regression, and Pearson correlation tests. 35.0% (n=88) used dietary supplements regularly, with a preference for multivitamins (50%) and protein supplements (30%). Knowledge was moderate (60% risk aware), attitudes favorable (70% in favor of counseling), but practice restricted (25% informed peers). Everyday use of dietary supplements escalated stress probability (OR=2.5, 95% CI: 1.8-3.4, p<0.001), with correlation (r=0.38, p<0.01). In conclusion, students have promise as dietary supplement champions but require additional training to close knowledge-practice gaps and mitigate mental health risks. Curriculum and policy interventions are needed to enhance students' abilities in encouraging rational dietary supplement use and identifying potential mental health effects.
