Synthesis, Characterization, and Effects of Aliphatic and Aromatic Amines on Thermal and Surface Properties of Zwitterionic Amphiphiles.

Solubility and thermal stability of surfactants are the key properties to consider for their possible oilfield applications. Most commercially available surfactants experience hydrolysis under high temperatures, and prolonged heating exacerbates this process, creating significant challenges for the petroleum industry. To address these complications, a novel class of propylamine and pyridinium-based zwitterionic surfactants was prepared, and their structures were confirmed using nuclear magnetic resonance (NMR) and Fourier transform infrared (FT-IR) spectroscopies.

Designing a multi-epitope vaccine targeting the HIV-1 subtype CRF01_AE in Indonesia.

HIV has markedly affected millions of people globally, with antiretroviral therapy (ART) transforming acquired immunodeficiency syndrome from a fatal disease to a manageable chronic condition. However, global disparities in ART access persist, particularly in low- and middle-income countries, highlighting the urgent need for affordable HIV vaccines. In this study, we investigated the potential development of a multi-epitope vaccine (MEV) targeting the HIV subtype CRF01_AE, which is prevalent in Indonesia.

Strengthening Indonesia's health system through community and technological engagements in public health interventions.

The 7th International Symposium on Public Health (ISoPH 2023), was held on October 2-3, 2023, in Surabaya, Indonesia, which brought together a diverse array of public health professionals, researchers, and policymakers from around the globe. The purpose of the symposium was to facilitate the exchange of the latest information and ideas within the realm of public health. The symposium aspired to foster discussions and the exchange of insights regarding scientific issues in the field of public health globally and within the context of Indonesia.
