Research ArticleOpen accessIn the abstractInflammatory Effects of Co-Exposure to Heavy Metals (Cd and Pb) and Respiratory Viruses (229E, OC43, and H3N2) on IL-6 and IL-8 Responses in U87 Glioblastoma CellsHyeokjun Yun, Qian-Wen Wang, Jae Kyung KimCo-exposure to heavy metals and viruses can pose threats to cellular health by increasing cytotoxicity and inflammatory cytokine expression. We aimed to elucidate the interactions between these factors inhuman glioblastoma cells (U87). U87 cells were exposed to influenza A virus (H3N2), coronaviruses OC43 and 229E, and heavy metals Cd and Pb. Cell viability and cytotoxicity were assessed through WST-8 and … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 5 Jul 2025 · 5,505 accessesView PDFCite
Research ArticleOpen accessIn the abstractCytokine Expression During the Early Response of A549 Cells to Infection with Influenza Virus, Alphacoronavirus and BetacoronavirusQian Wen Wang, Jae Kyung KimThe escalating incidence of coronavirus infections underscores the critical need for a comprehensive understanding of the differential impacts of Human Coronaviruses (HCoVs) belonging to the Alphacoronavirus and Betacoronavirus genera. This study investigated the varying effects of HCoV-229E (Alphacoronavirus), HCoV-OC43 (Betacoronavirus), and influenza A virus subtype H3N2 on A549 cell viability and cytokine expression. Results showed that H3N2 triggered a more … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 6 Jul 2024 · 4,554 accessesView PDFCite
Research ArticleOpen accessIn the abstractFermentation Conditions of Lactobacilli for the Production of Lactose-Free Starter CultureMadina K. Imanbayeva, Zhaksylyk K. Masalimov et al.This research aims to determine the fermentation conditions and viability in a medium simulating the gastrointestinal tract and to examine the antagonistic potential of Lactobacillus acidophilus (Lb. acidophilus) and Lactobacillus rhamnosus (Lb. rhamnosus) in producing a lactose-free starter. Our study examined Lactic Acid Bacteria (LAB). The sources of Lb. acidophilus strains are camel milk (shubat), Lb. rhamnosus mare milk (koumiss), … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 7 Feb 2024 · 4,746 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn vitro Antioxidant and Cytoprotective Potentials of Postbiotic ProbioMETA G55Xinyi Song, Ga Yeon Kim, Young Ki Lee, Jae Kyung KimStudies have demonstrated the favorable beneficial impact of probiotic metabolites on the skin. However, the use of postbiotics for skincare is a relatively new field despite their high safety and stability, which guarantee a longer shelf life. The postbiotic ProbioMETA G55(G55) is a skincare raw material, but none of the studies have evaluated the antioxidant capacity of G55 in skin … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 7 Aug 2023 · 4,953 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Japanese Quail Egg-Yolk Extender in Cryopreservation of Cockerel SemenRantloko Rolly Maapola, Khathutshelo Agree Nephawe, Tshimangadzo Lucky Nedambale et al.The purpose of this study was to examine the effects of quail egg yolk extenders in the cryopreservation of cockerel semen. Ten Venda cockerels were chosen randomly and semen was collected twice a week with a two-day rest period using an abdominal massage technique. Immediately following semen collection, semen samples were evaluated for microscopic parameters (sperm cell motility, viability, morphology, … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 1 · 25 Mar 2023 · 5,638 accessesView PDFCite
Research ArticleOpen accessIn the abstractHibiscus Flower Extract and Niacinamide Show Enhanced Whitening Effects in Mouse Melanoma Cells (B16F10)Jae Eun Choi, Tae Su Jang, Jung Min Park et al.Melanoma, a type of cancer that most often occurs on skin exposed to UV rays, is becoming increasingly common. Recent research has focused actively on using natural products. The goal of this study was to compare the melanin-inhibitory effects of Hibiscus (Hibiscus sabdariffa L.) flower Extract (HE) and Niacinamide (NA), a functional ingredient with whitening effects, on melanoma cells. The … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 1 · 9 Feb 2023 · 7,226 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of the Tensioactive Agent SDS on Extender’s Boar Semen Viability after ThawingMaria Helena Moreira da Silva, Loide Valadão, Fernando Moreira da SilvaEffects of the surfactant Sodium Dodecyl Sulfate (SDS) on the motility and viability of boar semen after thawing were evaluated. For such purpose, semen of twelve adult boars was collected twice a week, the rich portion of this semen was separated and frozen with different concentrations of SDS (0; 2.5; 5; 10; 20 and 40 mM). For freezing the semen … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 20 Jan 2021 · 7,795 accessesView PDFCite

Researchers hope to contribute to this through this research. Activities of both Ulvan extracted from Ulva lactuca and silver nanoparticles (Ag-NPs) were examined against seven different cancer cell types called (Caco2 cells, A549 cells, Mcf7 cells, Hep2 cells, HepG2 cells, PC3 cells, … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 30 Jun 2020 · 6,675 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelective Susceptibility of Human Bladder Transitional Cell Carcinoma T24 Cells towards NBD PeptideSankari Durairajan, Charles Emmanuel Jebaraj Walter, Kalaiselvi Periyandavan et al.Bladder cancer is a recurrent disease that often develops chemoresistance and is on the rise in developing countries. After diagnosis surgery followed by immunotherapy and/or chemo- radiation therapy are the available treatments. These treatments do not provide protection against disease progression or recurrence thus highlighting the need to identify and develop drugs that are capable of inhibiting bladder cancer.
