Research ArticleOpen accessEvery word in the titleQualitative Analysis of the Chemical Composition of Cinnamomum tamala leaves and Biological ActivityQianwen Gong, Pin Chen, Linyang Wang, Shuge TianCinnamomum tamala (Buch.-Ham.) Nees and Ebermaier. (Lauraceae) is a less explored medicinal plant in Uyghur medicine, with limited knowledge about its non-volatile compounds. We utilized chemical pre-screening in conjunction with UPLC-Q-Orbitrap-MS to analyze the phytochemical makeup of C. tamala leaves. Total polyphenols were measured using the Folin-Ciocalteu method, while total flavonoids were quantified through NaNO2-Al (NO3)3 colorimetric analysis across four … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 21 Sep 2026 · 659 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCyclodextrin Glucanotransferase Activity of Microbial Strains Isolated from Yam-Cultivation Soils in Northwestern BeninCyrille Alode Vodounon, Ténor Dias-Mendel Allode et al.β-Cyclodextrin, an industrially important oligosaccharide, is produced by microbial enzymes such as cyclodextrin glucanotransferase (CGTase). This study investigated ways to optimize the enzymatic activity of CGTase from Bacillus cereus, Bacillus pumilus, Bacillus brevis, and Bacillus subtilis strains isolated from soils in north-western Benin. Cyclization activity of CGTase and the influence of pH, temperature, and metal ions were assessed using conventional … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 21 Sep 2026 · 652 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMRI Observation and Analysis of Muscle Activity During ExerciseLi-Chang Zou, Hong-Wu LiWhile conventional biomechanical testing techniques are able to determine the mechanical characteristics of muscle tissue, they do not offer precise insight into how muscle metabolism and microstructure change in response to various types of exercise activities over the course of time. Using Magnetic Resonance Imaging (MRI) analysis of muscle tissue allows researchers to examine how different levels of intensity affect … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 30 Jul 2026 · 1,025 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEdge Computing Enabled Human Activity Recognition (ECEHAR) Using LSTM and CNNSuresh Kumar, M Y. Mohamed ParveesHuman Activity Recognition (HAR) is an important research area for various application domains such as healthcare, gaming, telemonitoring, and sports. However, executing HAR algorithms on remote servers or in the cloud have challenges in terms of high latency, increased bandwidth demand, and high energy consumption. Moving the computation to edge-assisted HAR is more effective and flexible solution to address the … …Journal of Computer Science, Vol. 22, Issue 3 · 6 Mar 2026 · 1,578 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUltrasonic Microwave Assisted Extraction, Chemical Characterization and Antioxidant Activity of Polysaccharides from Fig LeavesBaikangzhe Zheng, Yang Miao, Yi Zhou et al.This study employed ultrasonic-microwave-assisted extraction (UMAE) to isolate water-soluble polysaccharides from fig (Ficus carica L.) leaves (FLPs). Polysaccharide yield was used as the primary index to evaluate extraction efficiency. The effects of material-liquid ratio, microwave power, extraction temperature, and extraction time on polysaccharide yield were systematically investigated through single-factor experiments, followed by response surface methodology optimization. Structural characterization and antioxidant … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 3 Mar 2026 · 1,671 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparative Analysis of Surface Microhardness and Antimicrobial Activity of Conventional and Bioactive Composite Materials for Dental RestorationsBruno Fongaro Dalbosco, Rafael da Silva Vanolli, Poliana Maria de Faveri Cardoso et al.This study evaluated the fluoride release capability, antimicrobial activity, and surface microhardness of bioactive composite resins, critical properties for the effectiveness and durability of dental materials in restorative procedures. Conventional and bioactive composite resins with varying viscosities were tested. Specimens of each resin type were prepared and stored in physiological saline solution for 24 hours to simulate oral conditions. Surface … …Current Research in Dentistry, Vol. 16, Issue 1 · 29 Jan 2026 · 2,809 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDeep Sense: Deep Learning for Early Staging the Onset of Diabetes Emanating Recognition of Activity PatternsMohammed Shamsul Alam, Erfanul Hoque Bahadur, Md Fokrul Islam Khan et al.This study presents a comprehensive framework for Human Activity Recognition (HAR) using smartphone sensor data, with a specific focus on identifying activities associated with diabetic risk factors. We investigate the efficacy of two deep learning architectures (Long Short-Term Memory (LSTM) networks and Graph Convolutional Networks (GCNs)) for activity recognition under conditions of limited training data. To address data scarcity, we … …Journal of Computer Science, Vol. 21, Issue 10 · 15 Dec 2025 · 2,268 accessesView PDFCite
