Impact of Biofeedback-Integrated Classroom Environments on Emotional Regulation and Academic Performance in School Students

Abstract

This study investigates the role of biofeedback-integrated classrooms in enhancing emotional regulation and academic performance among school students. Emotional regulation is a critical aspect of learning, influencing attention, memory, and motivation. Traditional classroom methods often overlook the physiological and emotional needs of students, leading to suboptimal learning outcomes. Biofeedback, a technique that provides real-time physiological feedback to individuals about their heart rate, skin conductance, and brain activity, has emerged as a promising intervention to foster self-awareness and self-regulation skills. This research adopts a quasi-experimental design, involving 120 students from grades 6 to 8, divided into experimental (biofeedback-integrated classrooms) and control (traditional classrooms) groups. Physiological measures, standardized emotional regulation questionnaires, and academic performance scores were collected over a 12-week intervention period. Results indicate significant improvements in emotional regulation and academic performance among students in the biofeedback-integrated classrooms compared to the control group. The study suggests that incorporating biofeedback technology in educational settings can provide a holistic approach to learning, integrating cognitive and emotional dimensions. Implications for educators, policymakers, and curriculum designers are discussed, emphasizing the potential for technology-assisted emotional interventions to improve student outcomes.

The Impact of Pro-Inflammatory Diets on Endothelial Dysfunction Markers in Rheumatoid Arthritis: A Meta-Analytic Approach

Abstract

Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease with vascular complications often linked to endothelial dysfunction markers ICAM-1 and VCAM-1. Pro-inflammatory diets may exacerbate RA progression, but their impact on these biomarkers remains unclear. Objective: To systematically analyze and quantify the association between dietary factors worsening RA and circulating levels of ICAM-1 and VCAM-1 through meta-analysis. Methods: Major databases (PubMed, Scopus, Web of Science) were searched for studies reporting dietary exposures linked with RA severity along with ICAM-1 or VCAM-1 measurements. Standardized mean differences (SMD) were pooled using random-effects models. Heterogeneity and risk of bias were assessed. Results: A total of 39 studies including observational and interventional designs with diverse populations were analyzed. The pooled SMD for ICAM-1 was 0.81 (95% CI: 0.62 to 1.00, p < 0.001), and for VCAM-1 was 1.17 (95% CI: 0.73 to 1.61, p < 0.001), indicating significantly higher biomarker levels in RA patients consuming pro-inflammatory diets. Considerable heterogeneity was observed (I² = 83% for ICAM-1, 96% for VCAM-1). Subgroup analyses showed consistent effects across diet types and geographic regions. Conclusions: This meta-analysis elucidates the significant influence of pro-inflammatory diet on endothelial dysfunction biomarkers in RA, highlighting potential targets for dietary intervention to mitigate vascular risk.

Optimization of Probiotic-Fermented Beetroot-Spirulina Protein Health Drink Using Response Surface Methodology: Physicochemical, Microbial, and Sensory Attributes

Abstract

This study developed and optimized a probiotic fermented health drink by incorporating spirulina protein isolate (SPI, 68.2% purity) into beetroot juice using response surface methodology (RSM). Fresh beetroot juice (pH 4.45±0.12, Brix 12.5±0.4) was blended with 2-6% w/w SPI via high-shear mixing, sterilized, and fermented with Lactiplantibacillus plantarum MTCC 1325 and Lacticaseibacillus rhamnosus MTCC 5462 (1:1 consortium, proteolytic activity 2.1±0.2 U/mL). A central composite design (20 runs) optimized temperature (28-42°C), time (24-72 h), inoculum (2-5% v/v), and SPI levels, targeting viable counts (>10^9 CFU/mL), titratable acidity (0.8-1.2%), and sensory acceptability (>7/9). Optimum conditions (35°C, 48 h, 3.5% inoculum, 4% SPI) yielded 1.2×10^9 CFU/mL probiotics (R²=0.958, desirability 0.92), pH 3.98±0.11, acidity 0.92±0.05% lactic acid, and overall acceptability 7.9±0.79. Fermentation enhanced viscosity (42.6±2.1 cP, +31.5%), total phenols (28.4±1.6 mg GAE/100 mL, +43.4%), DPPH IC50 (78±4 μg/mL, -37.1%), and protein digestibility (89.6±2.1%, +14.6%) via synergistic proteolysis and betacyanin hydrolysis. Sensory profiling by 30 panelists confirmed superiority over 6% SPI (5.7±1.19, p6/9, and TPC/YM <10^4 CFU/mL, exceeding FAO/WHO minima. RSM validation (97.8% accuracy) supports scale-up for Indian markets, leveraging Haryana's beet production (2.1 Mt/year) and spirulina's sustainability. This beetroot-SPI synergy delivers a tangy, pink, protein-probiotic beverage masking algal off-notes while boosting functionality.

Comparative Analysis of Conventional and AI-Driven Threat Detection Systems in Real-Time Cybersecurity Operations

Abstract

The increasing volume and sophistication of cyber threats have challenged the effectiveness of conventional detection systems in real-time security operations. Traditional approaches based on predefined signatures and static rules often fail to recognize novel and evolving threats, leading to delayed responses and high false positive rates. This study presents a comparative analysis of conventional and AI-driven threat detection systems in order to evaluate their relative effectiveness across critical cybersecurity performance indicators. Using a quantitative comparative design, the study assessed a signature-based intrusion detection system alongside supervised machine learning, deep learning, and hybrid intelligence models. Evaluation was conducted using structured network intrusion datasets and system log data, with performance measured through accuracy, precision, recall, F1-score, response time, scalability, and computational efficiency. The results show that AI-driven systems consistently outperform conventional systems across all major performance criteria. The hybrid AI model achieved the best results, particularly in anomaly detection and response speed. The study concludes that AI-driven cybersecurity offers a more proactive, scalable, and adaptive defense mechanism for real-time digital protection. These findings support the strategic adoption of AI in modern cyber defense frameworks.

Abstract

स्वतंत्र भारत के निर्माण के साथ राष्ट्रीय सुरक्षा, सीमाई चुनौतियों और युद्धकालीन परिस्थितियों ने भारतीय राज्यों की सैन्य भूमिका को नए रूप में सामने लाया। हरियाणा उन प्रमुख क्षेत्रों में रहा है जहाँ सैनिक सेवा केवल रोजगार का माध्यम नहीं, बल्कि सामाजिक प्रतिष्ठा, पारिवारिक परम्परा, ग्राम्य गौरव, राष्ट्रभक्ति और बलिदान की संस्कृति से जुड़ी हुई रही है। प्रस्तुत शोध-पत्र का उद्देश्य स्वतंत्र भारत के संदर्भ में हरियाणा की सैन्य परम्परा का सामाजिक-ऐतिहासिक विश्लेषण करना है। इसमें भर्ती-परम्परा, रेजिमेंटीय संबद्धता, वीरता-पुरस्कार, युद्ध-सहभागिता, शहीद-स्मृति तथा राज्य-स्तरीय सार्वजनिक मान्यता जैसे आयामों का अध्ययन किया गया है। यह अध्ययन दर्शाता है कि हरियाणा की सैन्य परम्परा केवल युद्धभूमि तक सीमित नहीं है, बल्कि यह ग्रामीण समाज, पारिवारिक संस्कार, युवाओं की आकांक्षाओं, सामुदायिक संगठन और राज्य की स्मृति-राजनीति में भी गहराई से निहित है। स्वतंत्रता के बाद हुए प्रमुख युद्धों और सैन्य अभियानों में हरियाणा के सैनिकों की उपस्थिति ने इस परम्परा को निरंतर जीवित रखा। साथ ही, वीरता-पुरस्कारों और शहीद-सम्मान की संस्थागत व्यवस्था ने इस सैन्य संस्कृति को सामाजिक वैधता प्रदान की। यह शोध-पत्र इस निष्कर्ष पर पहुँचता है कि हरियाणा की सैन्य परम्परा भारतीय राष्ट्रीय सुरक्षा ढाँचे की एक महत्त्वपूर्ण सामाजिक नींव है।

Pharmacognostic Preparation, Hydroethanolic Extraction and Preliminary Phytochemical Screening of Apium graveolens L. Leaves

Abstract

Apium graveolens L. (celery) is an aromatic medicinal plant whose leaves contain chemically diverse constituents with potential antioxidant, anti-inflammatory and neuropharmacological relevance. The reliability of any pharmacological investigation depends first on correct plant authentication, controlled preparation of the raw material, reproducible extraction and preliminary characterization of the resulting extract. This study therefore focused specifically on the collection, authentication, shade drying, powdering, hydroethanolic extraction and qualitative phytochemical screening of A. graveolens leaves. Healthy mature leaves were collected from a local herbal garden, cleaned and authenticated by their characteristic morphological and organoleptic features. The leaves were shade-dried at room temperature, coarsely powdered and stored in airtight containers. One hundred grams of dried powder was extracted with 70% ethanol in a Soxhlet apparatus at approximately 60 degrees C for 24 h. The filtrate was concentrated under controlled conditions to yield a dark greenish-brown, aromatic, semisolid extract. The dried extract weighed 12.40 g, corresponding to a percentage yield of 12.40%. Standard qualitative tests were performed for alkaloids, flavonoids, glycosides, steroids, tannins, phenolic compounds, saponins and terpenoids. All eight targeted phytochemical classes were detected; flavonoids and phenolic compounds showed the strongest reactions, whereas alkaloids, glycosides, steroids, tannins, saponins and terpenoids were present at lower qualitative intensity. The findings establish a reproducible preparation procedure and demonstrate that the hydroethanolic leaf extract is rich in secondary metabolites that justify subsequent pharmacological and chromatographic investigation.
