Aedes aegypti is a primer vector of dengue virus (DENV) and chikungunya virus (CHIKV). The susceptibility of mosquitoes to DENV and CHIKV depends on their recognition receptor of pathogens. C-type lectins (CTLs) are an important mediator of virus infection in A. aegypti. This study aims to identify potential receptors and determine the binding affinity between ligand–receptor interaction, CTLs and virus envelopes (DENV-1, 2, 3, and 4 and CHIKV) interaction based on in silico analysis. Sample sequences were obtained from GenBank (NCBI), and 10 CTLs were acquired from VectorBase. Homology modeling based on a minimum standard of 20% was processed …
Synthesis Of Copper (Ii) Oxide Nanoparticles Using Vitis Vinifera L. Leaf Ex-Tract And Its Application As A Catalyst In Doebner Reaction, Felie Virgayani Kurniawan, Antonius Herry Cahyana, Rika Tri Yunarti
Synthesis Of Copper (Ii) Oxide Nanoparticles Using Vitis Vinifera L. Leaf Ex-Tract And Its Application As A Catalyst In Doebner Reaction, Felie Virgayani Kurniawan, Antonius Herry Cahyana, Rika Tri Yunarti

Plant extracts can be used to synthesize nanoparticle because it is efficient, economical, and friendly to the environment. Copper oxide nanoparticles (CuO NPs) were synthesized using an aqueous fraction of Vitis vinifera L leaf extract and Cu(NO3)2 solution as a precursor. This fraction contains secondary metabolites as a reduction agent and stabilizing agents to formed CuO NPs. CuO NPs can be used as a catalyst in a chemical reaction, one of which is the Doebner reaction, which is a simple and efficient reaction of aniline, aromatic aldehydes, and pyruvic acid under reflux conditions to produce derivatives quinoline-4-carboxylic …

Avian Influenza (AI) is one of the strategic animal diseases still considered a priority for control by the Indonesian government. This study aimed to examine the immune response of chickens to various types of H5N1 subtype AI vaccines in Indonesia and to determine the correlation of factors influencing the post-vaccination AI antibody response. Serum samples were tested using the hemagglutination inhibition (HI) test with the standard AI antigen subtype H5N1 strain A/Chicken/Barru/BBVM/41-13/2013 (Clade 2.1.3) and strain A/Chicken/Semarang/04141225-07/2014 (Clade 2.3.2). Antibody titer was calculated using the Geometric Mean Titer (GMT). The correlation analyses were performed to assess the correlation of antibody …

Technological developments have prompted the production of highly advanced smartphones. However, various advanced features cause smartphones to heat up quickly and emit more electromagnetic radiation, which harms human health. Smartphone protection is needed to solve these issues. This study aims to create a film from the S. trifasciata plant based on polyvinyl alcohol (PVA) to reduce electromagnetic and thermal radiation on smartphones. S. trifasciata plants were macerated with acetone and partitioned with n-hexane, dichloromethane, ethyl acetate, and water. The films were made by mixing PVA with the four fractions. Among the four layers of film, the PVA + water …
Jatropha Tanjorensis A Flora Of Southeast Nigeria: Isolation And Characterization Of Naringenin And Validation Of Bio-Enhanced Synergistical Activity Of Α- Tocopherol Toward Clinical Isolates Of Resistant Bacterial, Ikechukwu Kingsley Ijoma, Vincent Ishmael Egbulefu Ajiwe

Jatropha tanjorensis is among the rich floras of Southeast Nigeria and used by ethnic people to treat infections and manage health conditions. Ethnomedicine has long been employed in the treatment of ailments caused by bacterial pathogens. Studies showed that the incorporation of synthetic α-tocopherol to an antibacterial agent improves its activity. However, knowledge about the antibacterial-enhanced activity of plant-based α-tocopherols, especially those isolated from Jatropha tanjorensis, is limited because of the different bioactivities of synthetic and natural α-tocopherols. To determine the phytochemicals in J. tanjorensis, we carried out the structural elucidation of its leaf extracts. Naringenin and α-tocopherol …
