Malaria is considered one of the most important scourges that humanity has faced during its history, being responsible every year for numerous deaths worldwide. The disease is caused by protozoan parasites, among which two species are responsible of the majority of the burden, Plasmodium falciparum and Plasmodium vivax. For these two parasite species, the questions of their origin (how and when they appeared in humans), of their spread throughout the world, as well as how they have adapted to humans have long been of interest to the scientific community. In this paper we review the existing body of knowledge, including current research dealing with these questions, focusing particularly on genetic and genomic analyses of these parasites and comparison with related Plasmodium species infecting other species of host (such as non-human primates).

Background: Novel antimalarials are needed to address emerging resistance to artemisinin and partner drugs. We did two trials to evaluate safety, tolerability, pharmacokinetics, and activity against blood stage Plasmodium falciparum for the drug candidate MMV533.
Methods: A phase 1a first-in-human (FIH) trial was conducted at Nucleus Network (Melbourne, VIC, Australia).

Background: The study aims to determine the host preference for blood feeding among potential hosts of Anopheles stephensi in Iran, using the Multiplex-PCR method. An. stephensi is the primary malaria vector in urban areas of South Asia and the Middle East, including southern Iran, where approximately 30.

Background: Malaria remains a critical disease. Leucinostatins from the fungus Purpureocillium lilacinum inhibited the transmission of Plasmodium falciparum to mosquitoes via contact.
Methods: Here, we modified the leucinostatin B (LB) C-terminus to make derivatives and examined their inhibition against malaria transmission to mosquitoes.

The Knops blood group system is an independent blood group system recognized by International Society of Blood Transfusion (ISBT) in 1992, and latest time consisting of 13 antigens carried on a glycoprotein of 2489 amino acids and called the Complement C3b/C4b Receptor 1 (CR1). Erythrocyte KN antigen was first reported in 1970, and CR1 is a protein coding gene that is a member of the receptors of complement activation (RCA) family and is located in the "cluster RCA" region of chromosome 1. CR1 is an important participant in the erythrocyte immune machinery and plays an major role in inhibiting complement activation, and polymorphisms in its expression have been closely associated with a variety of diseases, including systemic lupus erythematosus (SLE), malaria, Plasmodium falciparum malaria, Alzheimer's disease (AD) and leprosy.

Brazilian Red Propolis (BRP) is a natural product known for its rich chemical composition and therapeutic potential. This study investigates the phytochemical profile and evaluates the cytotoxic, antiplasmodial, and antimicrobial properties of red propolis extract and its isolated compounds vestitol (1), neovestitol (2), medicarpin (3), 7-O-methylvestitol (4), and oblongifolin B (5). The extract showed selective cytotoxicity against cancer cell lines (IC: 16-39 μg/mL).
