Research ArticleOpen accessIn the keywordsA Quantum Mechanical Study of Structural and Electronic Dilution Effects in Paramagnetic Chemical Exchange Saturation Transfer AgentsWhelton A. Miller III, Preston B. MooreWe present a computational study of the effect of chemical modifications of the meta and para substituents in the coordinating pendant arm of a modified 1,4,7,10-tetraazacyclododecane-N, N’, N’’, N’’’-tetraamide (DOTAM) ligand on the Chemical Exchange Saturation Transfer (CEST) signal. Magnetic Resonance Imaging (MRI) is currently one of the most widely used techniques available. MRI has led to a new class … …Journal of Organic and Biomolecular Simulations, Vol. 1, Issue 1 · 11 Dec 2013 · 28,364 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMass Production of Uniformly Sized Air-Filled Poly-Lactic Acid Microcapsules Made from Microbubble TemplatesJay Molino, Svetlana Jojlova, Hirofumi Daiguji, Fumio TakemuraHollow poly(Lactic Acid) (PLA) microcapsules were fabricated using the bubble template method. In this method, microbubbles nucleated inside droplets of a dichloromethane solution of PLA which were located in a continuous phase of poly(vinyl alcohol). PLA-covered microbubbles formed when PLA adsorbed to the bubble surface by physisorption. Then, the coated microbubbles were spontaneously released from the droplet´s interior into the … …American Journal of Applied Sciences, Vol. 16, Issue 7 · 20 Aug 2019 · 7,756 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcaricidal Activity of Azadirachta indica (Neem Tree) and Carica papaya (Papaya) Leaf Extracts against Rhipicephalus sanguineus (Dog Ticks) Using Spray MethodAlfredo Vita Corpuz, Carmela Montoya Florentino, Paul Erman Tabuloc Quilana et al.Ticks pose a serious threat to dogs, with synthetic acaricides leading to environmental impact and resistance concerns. While Azadirachta indica and Carica papaya have shown acaricidal potential against Rhipicephalus sanguineus, their efficacy against dog ticks has not been thoroughly investigated. This study determined the acaricidal activity of A. indica and C. papaya leaf extract against R. sanguineus, both individually and … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 22 Apr 2025 · 8,409 accessesView PDFCite
Short CommunicationsOpen accessIn the abstractHuman Babesiosis Caused by Babesia odocoilei: A Confirmed ZoonosisJohn Donald ScottBabesia odocoilei has been gaining attention as a novel agent of tick-borne disease. Researchers allege that the American dog tick is a vector of B. odocoilei, but supportive evidence for this contention is absent. Likewise, B. odocoilei was allegedly found in two European patients, but supportive evidence for this postulate is lacking and it appears that the patients were infected … …American Journal of Infectious Diseases, Vol. 20, Issue 4 · 21 Jan 2025 · 9,864 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro and in Silico Evaluation of Bioactive Compounds from Usnea longissima Ach. as Antimicrobial AgentsOky Kusuma Atni, Erman Munir, Nursahara Pasaribu et al.Lichens, formed from symbiotic association between of fungi with phototrophic organisms, generate a variety of bioactive chemicals having medicinal potential. This research aimed to examine the antibacterial characteristics of Usnea longissima Ach. using both in vitro and in silico methodologies. The effectiveness of lichen methanol extracts against different diseases was evaluated using the disc diffusion technique. Pathogens included gram-positive, gram-negative, … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 10 Feb 2026 · 1,721 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological Diversity of Isolated Mycobacterial Cultures in the Republic of Kazakhstan: Implications for Diagnostics and TreatmentAssiya Borsynbayeva, Kairat Turgenbayev, Gulzhauhar Sarsenova et al.The study of mycobacterial morphology in the Republic of Kazakhstan is relevant due to the increasing burden of tuberculosis and other mycobacterial diseases. The aim of this study was to comprehensively describe the morphological characteristics of different mycobacterial species identified in Kazakhstan, which will help to improve diagnostic methods and develop new approaches to treatment. Comparative and cross-cultural analyses were … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 1 Dec 2025 · 2,203 accessesView PDFCite
Research ArticleOpen accessIn the abstractATRA AS A POTENTIAL ANTIMETASTATIC AGENT IN COLORECTAL ADENOCARCINOMARobert Edwards, Kambiz Afrasiabi, Kehui WangThe family of Retinoic acid compounds have long been the subject of intense study and interest as chemo prophylactic agents. This dates back to their therapeutic effect in leukoplakia Where ATRA was shown to lead to the reversal of premalignant lesions and Subsequent reports on their use in metastatic colorectal adenocarcinoma and a vast array of other malignant disorders as … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 26 Mar 2014 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantification of Zolpidem in Canine PlasmaMario Giorgi, Alessandra Gavazza, Hyoin YunProblem statement: Zolpidem is a non-benzodiazepine hypnotic agent currently used in human medicine. In contrast to benzodiazepines, zolpidem preferentially binds with the GABAA complex ϖ1 receptors while poorly interacting with the other ϖ receptor complexes. Recent studies have suggested that ZP may be used to initiate sedation and diminish severe anxiety responses in dogs. The aim of the present study … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 1 · 19 Mar 2012 · 7,908 accessesView PDFCite
