Research ArticleOpen accessEvery word in the titleLarvicidal Activity of Spondias purpurea (Sineguelas) Leaf and Hylocereus costaricensis (Dragon Fruit) Stem Extracts Against Aedes aegyptiAlfredo V. Corpuz, Nigell Mikhail A. Gallardo, Ace Danielle C. AveroThe study determined the larvicidal activity of the different concentrations of Spondias purpurea and Hylocereus costaricensis extracts by measuring percent mortality in Aedes aegypti larvae, a primary vector of dengue and other arboviral diseases. The hypothesis proposed that combining both extracts would yield greater larvicidal activity due to potential synergistic interactions. Ethanolic extraction was used to isolate a wide array … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 20 Nov 2025 · 2,417 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Antidiabetic Efficacy of Combined Extracts from Two Continental Plants: Azadirachta indica (A. Juss) (Neem) and Vernonia amygdalina (Del.) (African Bitter Leaf)Patrick Ekong Ebong, Item Justin Atangwho, Eyong Ubana Eyong, Godwin Eneji EgbungPolyherbal therapy is said to be a current pharmacological principle having the advantage of producing maximum therapeutic efficacy with minimum side effects. We assessed the antidiabetic efficacy and hence the impact on biochemical indices of toxicity by a combination of extracts from neem and bitterleaf. Thirty rats, 25 diabetic and 5 non-diabetic rats, were used for the study. The diabetic … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 31 Aug 2008 · 14,400 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHarmonic Mean Projection Shape Transform for Leaf ClassificationSophia Jamila Zahra, Riza Sulaiman, Seyed M.M. Kahaki, Anton Satria PrabuwonoShape feature extraction has emerged as an important part of computer vision and image processing applications. Identification of shape objects in huge data based on shape similarity still remains a challenging problem due to the similarity of the shapes and existing of classes with similar contour information. This paper presents to investigate the shape analysis for plant leaf classification by … …Journal of Computer Science, Vol. 16, Issue 9 · 13 Sep 2020 · 6,854 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReprocess of Copper from Worn Printed Circuit BoardsSwarnambiga A.K., M. Vidya Kalaivani, Sarah Sathyawathi, T.S. Ramyaa LakshmiThe objective of the study is to reuse printed circuit boards which are mainly made of copper. Most top down and bottom up approaches for the synthesis of Copper nanoparticles (CuNPs) needs pure copper (II) sulfate or any other copper salts as a raw material. For the expensive non-ecofriendly reasons, here we used wasted Printed Circuit Boards (PCBs) as an … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 12 Feb 2019 · 7,484 accessesView PDFCite

UsohProblem statement: To evaluate the effects of the water extract of the leaves of mistletoe (Loranthus micranthus) (traditionally used antidiabetic and antihypertensive) in male albino Wistar rats. Approach: The animals were divided into 4 groups (n = 6). Water extract of L. micranthus leaves was administered in graded doses of 0, 275, 551 and 827 mg kg-1 body weight (wt) … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 8,539 accessesView PDFCite
Research ArticleOpen accessIn the keywordsResponse Surface Optimized Ultrasonic Assisted Extraction of Total Flavonoids from Walnut Leaves and In Vitro Antibacterial ActivitiesYuanda Song, Aydin Berenjian, Han Wu et al.In this paper, the optimum extraction conditions of total flavonoids extracted from walnut leaves subjected to Ultrasonic Assisted Extraction (UAE) were optimized by Response Surface Methodology (RSM). The mathematical model showed the high coefficient of measurement (R2 = 0.9938) which indicated that this model could be used to guide the response surface methodology. The optimum extraction parameters for extracting flavonoids … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 24 Oct 2017 · 7,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpsilon-Insensitive Primal Loss With Support Vector Machine for Robust Cotton Leaf Disease ClassificationPavana Kumar Eramachetty Dhanajayalu, Malathi Sivasamy, Chitveli Siva Balaji YadavCotton diseases significantly reduce both yield and quality of crops, making early and accurate identification of the disease crucial for effective prevention and control. However, achieving a balance between lightweight models and precise classification of cotton diseases remains challenging. This difficulty arises primarily from the dispersed nature of disease symptoms and interference from noisy backgrounds, which complicate the detection process. … …Journal of Computer Science, Vol. 22, Issue 6 · 5 Aug 2026 · 755 accessesView PDFCite
