Abstract

Sexually transmitted diseases (STDs) are diseases with a high prevalence rate. The World Health Organization (WHO) estimates that more than 1 million STDs are transmitted every day, those diseases are chlamydia, syphillis, trichomoniasis, ghonorroea, and virus caused diseases (hepatitis B virus, immunodeficiency virus, human papillomavirus, and herpes simplex virus). Early and accurate examination and detection are important to help with the healing and control of these diseases. One of the examination methods that could be used is using the laboratory diagnostic methods which contribute to 40% to 60% of the process of diagnosing a disease. Thus, early detection not only helps control the spread of STDs but also facilitates the healing process. However, in Indonesia there are obstacles in the examination of diseases due to several factors, such as inadequate surveillance system and limited examination facilities, so that most people are undiagnosed. Therefore, this review will discuss in more depth the development of diagnostics for sexually transmitted diseases in Indonesia and globally. Global development in diagnostics is very broad and diverse, in which many diagnostic techniques has already been established. The development of diagnostic techniques has progressed rapidly from simplex assays to multiplex and also computerized assays. Diagnostic techniques in Indonesia has also developed and some of the local kits have already been in the market showing that Indonesia is already moving towards production of local diagnostics.

Abstract

The investigation of mRNA development has gained substantial interest, particularly in the ex vivo and in vivo therapy. mRNA is widely used for the development of gene editing-based therapies and mRNA vaccines. The aim of this study was to optimize the medium and harvest time to increase plasmid DNA production as part of mRNA production. This study modified used a medium modification approach to achieve high density culture of Escherichia coli TOP10 pGEMT-N in batch cultivation method. Various media formulations were assessed, including LB; LB with phosphate buffer (K2HPO4 12.549 g/L and KH2PO4 2.31 g/L); LB with glycerol (50 g/L); LB with glycerol and phosphate buffer; LB with phosphate buffer, glycerol, glucose (15 g/L), and galactose (15 g/L). The effect of additional carbon sources and phosphate buffer on culture density was measured through OD600 and wet cell weight analysis. The highest OD600 and wet cell weight was observed when LB with glycerol and phosphate buffer was used, with OD600 of 4.78±0.14 and wet cell weight of 36.00±0.63 mg/ml. Plasmid DNA was subsequently isolated from these cultures following 5- and 7.5-hour incubation periods. The utilization of LB medium with glycerol and phosphate buffer resulted in a substantial increase in the volumetric concentration of plasmid DNA of 1,516.97±385.00 ng/ml after 5 hours of incubation. In conclusion, a remarkable enhancement in plasmid DNA volumetric yield within 5 hours was achieved by addition of glycerol and phosphate buffer to LB medium, leading to incubation period.
