STI symptoms can manifest at different times, depending on the sex, age, and infection route. Here, we aimed to assess the occurrence of STIs in the Republic of Korea, explore associated global trends, and identify pathogens with high positivity rates to inform future health policies. … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 29 Jan 2026 · 1,934 accessesView PDF Cite

Research ArticleOpen accessComparative Antioxidant Effects of Essential Oil Blends and Individual Oils Using the DPPH Radical-Scavenging AssaySunghun Jang, Jae Kyung KimOxidative stress is recognized as a major contributor to conditions such as cancer, aging, and inflammation. Consequently, there is a growing interest in the use of natural antioxidants, particularly essential oils, owing to their safety benefits and potent antioxidant properties. The aim of this study was to evaluate the antioxidant effects of four essential oil blends (Refresh, Zest, Revitalizing, and … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 5 Jan 2026 · 2,659 accessesView PDF Cite

Research ArticleOpen accessTrends in the Prevalence of Clostridioides difficile Using Real Time PCR in South Korea (2020-2024)Yonghee Lee, Yoo Na Chung, Jae Kyung KimClostridioides difficile is a major cause of infection in healthcare settings, and frequent antibiotic use exacerbates its occurrence. C. difficile infection (CDI) is a major public-health challenge owing to its complications and high mortality rate. We aimed to analyze current trends in C. difficile prevalence. This study was a retrospective, single center analysis of 7,371 samples from April 2020 to … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 3 Oct 2025 · 2,363 accessesView PDF Cite

Research ArticleOpen accessComparative Evaluation of Synergistic Antibacterial Effects in Blended Essential Oil against Gram-Positive and Gram-Negative PathogensMin-Gi Kwon, Jae Kyung KimThe rising emergence of multidrug-resistant bacteria has heightened the search for novel antibiotic agents. Essential Oils (EOs) are complex combinations of volatile organic compounds generated by plants, with many exhibiting significant antimicrobial properties. This study evaluates the antibacterial movement of single and blended EOs against representative gram-positive bacteria Staphylococcus aureus and Methicillin-Resistant S. aureus (MRSA) and gram-negative bacteria Escherichia coli … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 7 Jul 2025 · 5,485 accessesView PDF Cite

Research ArticleOpen accessInflammatory 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 · 5,506 accessesView PDF Cite

Research ArticleOpen accessHuman Papillomavirus Genotypes in the Korean Older Adult Population Running Head: HPV Genotypes in Korean Older AdultsJieun Hwang, Hee Seung Song et al.In older populations, Human Papillomavirus (HPV) infections are likely to reactivate owing to immunocompromised, thereby increasing the risk of cervical and other cancers. However, research on HPV infection in older adults is limited and data on the sex- and age-specific distribution of high-risk HPV types are lacking. Thus, to increase the level of evidence on the extension of cervical cancer … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 6 Dec 2024 · 5,019 accessesView PDF Cite

Research ArticleOpen accessAnalysis of the Utility of MPT64, Drug Susceptibility Testing and Tuberculosis/Nontuberculous Mycobacteria Reverse Transcription Polymerase Chain Reaction for Tuberculosis Diagnosis and Efficiency Compared with Traditional CultureHo Keun Choi, Ga Yeon Kim, Tae Soung Kim, Jae Kyung KimDefining the molecular mechanisms underlying the dormant state of Mycobacterium tuberculosis (MTB) is essential for developing more effective treatments for tuberculosis (TB) infection. We investigated the positivity and resistance rates of TB tests on 6,174 samples referred to a single hospital. Of these, 342 cases (5.5%) were confirmed as positive by acid-fast bacilli staining, 243 cases (71.1%) were detected as … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 5 Dec 2024 · 4,211 accessesView PDF Cite
