This review explores the interplay between COVID-19 and malaria, with a focus on pregnant women. The concurrent infection of SARS-CoV-2 and malaria presents significant challenges in diagnosis, treatment, and management due to overlapping symptoms and complex immune responses. Genetic factors, particularly variations in the angiotensin-converting enzyme 2 (ACE2) receptor, play a crucial role in determining disease susceptibility and severity. Malaria-induced immunomodulation may influence the clinical progression of COVID-19, though the precise impact remains uncertain. The review emphasizes the need for integrated diagnostic and therapeutic approaches to effectively manage co-infections and improve maternal and fetal health outcomes. It underscores the importance of timely intervention and enhanced diagnostic methods to better understand and address these interactions. This review aims to bridge gaps in current knowledge and pave the way for future research and targeted therapeutic interventions, addressing a significant yet often overlooked public health challenge.

Chirality is one of the essential attributes of nature. Chiral drugs refer to a class of drugs containing chiral centers, and the molecular stereo-structures of their enantiomers are non-superimposable mirror images of each other. Sixty percent of commonly used drugs, including those from traditional Chinese medicine (TCM), are chiral. Developing a single enantiomer with high efficiency and low toxicity has drawn considerable attention due to significant differences in pharmacological activities, metabolic processes, and toxicity exhibited by the enantiomers of chiral drugs. This review concisely summarizes chiral drugs, including their sources, absolute configuration identification, pharmacological applications, and future research trends, particularly in TCM.

Since the early 20th century, viral infections such as SARS, dengue fever, AIDS, Ebola, influenza and herpes have been among the most common causes of illness and death worldwide. These viruses multiply quickly and lead to epidemics and pandemics. Unfortunately, no drug has been proven to be therapeutically effective in treating or preventing dengue fever. The focus of the review is on computational approaches such as molecular docking and simulation methods to evaluate the stability, inhibition mechanisms and binding interactions of rosmarinic acid (RA) against dengue virus proteins. Based on computational studies, it can be concluded that RA could hinder the spread of dengue virus due to its significant binding and docking affinities with its proteins. Due to its anti-inflammatory properties, broad-spectrum antiviral activity, and desirable low-toxicity pharmacokinetic profile, it is also a viable drug for further experimental validation. The review concludes by discussing how to interpret the in silico data, the shortcomings of the computational method, and the need for further experimental validation to fully explore the potential of RA as a treatment option for dengue.

Researchers have developed a new flexible material that can attenuate radar signals using tree bark waste as core raw source. The innovative material combines silicone rubber with sustainable carbon derived from tree bark, resulting in an eco-friendly alternative to traditional, high-cost technologies. Despite being made from natural waste, the new material can perform just as well as expensive nanocarbons, offering a greener and more affordable option to attenuate electromagnetic signals.

This study reviews the most recent studies about the biosynthesis and characteristics of circRNAs in diagnosis, treatment and prognosis evaluation, as well as the value of circRNAs in clinical applications as biomarkers or therapeutic targets in breast cancer. Understanding the mechanisms by which circRNAs function could help transform basic research into clinical applications and facilitate the development of novel circRNA-based therapeutic strategies for breast cancer treatment.
