Therapeutic Potential Of Lactiplantibacillus Plantarum Probio87 In Modulating Hpv Viral Load, Vaginal Health, And Immune Response In Hpv-Positive Women
(2024-12)
Xu, Pei
High-risk hpv infection is the primary cause of cervical cancer, the fourth most common cancer among women. Current treatment options are limited, and recurrence rates remain high. Probiotic administration presents a promising, safe, and cost-effective strategy for managing hpv infections. The probiotic properties of lactiplantibacillus plantarum probio87 fulfilled the requirements for probiotics, including its carbohydrate utilization, acid tolerance, bile tolerance, antimicrobial ability, symbiosis properties, prebiotic utilization, mucin adhesion, haemolysis, hydrogen peroxide production, and antibiotic resistance profile. The inhibitory effects of l. Plantarum probio87's cell-free supernatant (cfs) were tested in vitro on cervical cancer cell lines using the mtt (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) test, the angiogenesis assay, and the cignal finder reporter & dual-glo® luciferase assay. The results demonstrated that the cfs of l. Plantarum probio87 significantly (ρ < 0.05) inhibited the growth of hpv-mediated cervical cancer cell lines (hela and caski) compared to the negative control group. However, in c-33a (non-hpv related) cells, there was no obvious difference (ρ > 0.05). Furthermore, this probiotic inhibited the generation of solid angiogenesis promoters in all three cancer cell lines.
Remediation Of Tropical Soil Contaminated With Polycyclic Aromatic Hydrocarbons Through Advanced Oxidation Process
(2024-12)
Qutob, Mohammad Isam Mohammad
Polycyclic aromatic hydrocarbons (pahs) are chemicals classified as priority pollutants. Ninety percent of those released into the environment end up in the soil, which makes suitable soil remediation techniques necessary. Advanced oxidation process (aop) is one of the most efficient methods for the remediation of pahs from soil. In aop systems, the catalysts derived from natural iron minerals offer several advantages. However, their utilization in soil remediation is restricted due to the presence of soil impurities, which can inhibit the catalytic activity of these minerals. The soils in tropical regions relatively low in impurities, this enhances the efficiency of utilizing natural iron minerals from tropical soil as a catalyst. In this regard, the catalytic potential of naturally iron-bearing tropical soil was investigated to eliminate phenanthrene (phe), pyrene (pyr), and benzo[α]pyrene (b[α]p) using an oxygenated reactor supported with persulfate (ps). The system showed an efficient performance, and the removal efficiencies under the optimum conditions were 81%, 73%, and 86% for phe, pyr, and b[α]p, respectively.
Ethanol Extraction, Purification, Antioxidant Properties, And In Vivo Anti-Ageing Effects Of White Tea Flavonoids
(2024-10)
Yang, Yuhua
Based on the differences in qualities, white tea can be divided into four grades: “Shou Mei” (SMT), “Gong Mei” (GMT), “Bai Mu Dan” (White Peony, WPT), and “Bai Hao Yin Zhen” (Silver Needle, SNT). These teas were reported to have various potent bioactivities, such as antioxidant, anti-inflammatory, and anticancer activities. These health functionalities can be traced back to flavonoids found naturally in tea. This study aims to investigate the anti-ageing effects of purified flavonoids from white tea.
Carbon Dioxide Exchanges Between The Atmosphere And Seawater At The Northern Straits Of Malacca Using The Eddy Covariance Method And Remote Sensing
(2024-10)
Swesi, Abdulghani Essayah Musbah
Owing to its numerous sources and sinks, carbon dioxide (CO2) is one of the best-known climatically important gases that exhibits significant temporal and geographical variations. Therefore, we investigated sources and sinks of carbon in a tropical coastal area. This study focuses on the variables influencing the coastal input and output of carbon flux of the sea.
Image Classification On Ex-Mining Land Area Using Echo Classifier
(2003-10)
Baharuddin, Salmah
The purpose of this study is to map the landcover ofa large and complex surface of an ex-mining land area using remote sensing technology. Remote sensing imagery has proven useful to generate landcover and it is timely, potentially less expensive than conventional ground methods. Study goals included evaluation of various classification algorithms, deriving a landcover map of the ex-mining land using satellite image and collection of ground truth points in order to perform a more quantitative analysis and accuracy assessment of the methods used.
