Abstract

dengue fever (DF). Meanwhile, chikungunya virus causes Chikungunya fever (CF). These diseases involve three organisms, namely virus, mosquito Aedes sp., and human. The transmission of dengue and chikungunya virus is related to the population of Ae. aegypti. Banyumas regency is one of the regions with many cases of dengue and chikungnya virus infections, particularly in Purwokerto, Sokaraja, and Cilongok sub-district. Up to this time, there is no medicine and vaccine provided to treat these viruses effectively. Thus, detection of virus inside vector will be effectively performed in order to predict the transmission risk of dengue and chikungunya virus. This research aimed to know the molecular detection of dengue and chikungunya virus on adult Ae.aegypti mosquito in Sokaraja Region, Banyumas Regency. Survey was done by a cross-sectional method in Sokaraja sub-district from May 2019 – March 2019. Furthermore, technical sampling that used was purposive sampling method of adult Ae.aegypti using BG-Sentital Trap, followed by molecular detection of dengue virus using Two-step RT-PCR and chikungunya gene virus using RT-PCR. Molecular detection of DENV and CHIKV of mosquitoes which collected from Sokaraja region showed negative result

Abstract

Background: Breast cancer remains the most prevalent cancer among women globally, with significant mortality rates. Traditional therapies, such as surgery, chemotherapy, and radiotherapy, are associated with severe side effects and resistance, highlighting the need for alternative treatments. Electro-Capacitive Cancer Therapy (ECCT) is a promising non-invasive approach that uses low-intensity electric fields to selectively target cancer cells. Objective: This study aims to investigate the molecular mechanisms of ECCT, particularly its effects on key molecules such as PDGF and IL-1 in a DMBA-induced rat breast cancer model. Materials and Methods: The study used a post-test-only control group design with four groups: NINT (normal tissue), NIT (untreated tumor tissue), INT (DMBA-induced tumor tissue), and IT (ECCT-treated tumor tissue). ECCT was applied at 150 kHz for 21 days. mRNA expressions of PDGF and IL-1 were quantified using quantitative RT-PCR. Results: ECCT significantly reduced the mRNA expression of PDGF and IL-1 in treated tumor tissues (IT) compared to untreated tumor tissues (INT), bringing their levels closer to those observed in normal tissue (NINT). This suggests that ECCT downregulates key pro-angiogenic and pro-inflammatory molecules involved in tumor progression. Conclusion: In conclusion, the non-contact ECCT with a frequency of 150 kHz might downregulate PDGF and IL-1 mRNA expression in rat breast tumor tissue.
