Abstract

Recombinant protein Fim-C S.typhi is a potential protein that can be used as an alternative typhoid vaccine and produced on a large scale. However, before entering into a large-scale stage, laboratory optimum data on the factors that affect the production process of Fim-C Salmonella typhi proteins are required. This study aims to obtain information regarding the effect of host cell number E.coli BL21 (DE3) pLysS and overexpression time on production of recombinant protein Fim-C Salmonella typhi as the basis for developing candidate of typhoid vaccine. The optimization process of overexpression was done by adding 0.5 mM IPTG (Isopropyl-β-D-thiogalactopyranoside) inducer into bacterial cultures of 2%, 4%, and 6% with 4, 5, and 6 hours over expression. The measurement of the concentration of Fim-C recombinant protein extracted samples were done by a spectrophotometric method used BCA Kit Assay Thermo ScientificTM with wavelength 590nm. The characterization of those protein extracts was performed using SDS-PAGE method. The results from the study concluded that the number of 4% E.coli bacterial cells and four-hour overexpression time are the optimum condition of Fim- C Salmonella typhi characterized by the presence of high-intensity bands at ± 31 kDa.

Abstract

Two xanthone derivatives, garciniaxanthone E (1) and 12b-Hydroxy-des-D-garcigerrin A (2) have been isolated from ethyl acetate extract of the tree bark of Garcinia dulcis. The Ultraviolet (UV), Infrared (IR), Nuclear Magnetic Resonance (NMR), and Mass Spectrometry (MS) data analysis elucidated the structure of the isolated compounds. This study represents the first evaluation of compounds 1 and 2 in terms of their efficacy against receptor tyrosine kinases. The results showed that compound 1 exhibited weak activity with 12% inhibition against Insulin Receptor (InsR), while compound 2 showed moderate activity with 29% inhibition against epidermal growth factor receptor (EGFR). A molecular docking study targeting EGFR-TK suggests that the hydroxyl group at C-4 on compound 2 can be demolished to raise the inhibitory activity in future research.

Abstract

According to the World Health Organization (WHO), harmful agents such as Bacillus cereus and Listeria monocytogenes are responsible for 600 million cases of disease and 420,000 deaths annually. This research aims to test the effectiveness of the real-time PCR method for developing a prototype kit to detect pathogenic bacteria in processed meat. As a comparison, the and conventional PCR methods were used to obtain the accuracy, specificity, sensitivity, and effectiveness of the real-time PCR method. All the samples were cultured in solid media agar, performed amplification using specific primers cyt-K 2 and hly using PCR and real-time PCR. Meatballs, nuggets, and sausages, five samples each, were found to be positive positively contaminated with all targeted bacteria. However, they did not provide specific results using solid media culture and the PCR method. In addition, the real-time PCR method using prototype kit formulas accomplished that all contaminated samples had a Ct value smaller than the negative control, NTC (No Template Control), and had a similar melting curve to the positive control. This establishes that the real-time PCR method clarifies that all samples were contaminated with target bacteria. A formula was developed in the prototype kit with real-time PCR methods that can be used and applied on a commercial scale efficiently and precisely.
