Procollagen I N-terminal peptide correlates with inflammation on sacroiliac joint magnetic resonance imaging in ankylosing spondylitis but not in non-radiographic axial spondyloarthritis: A cross-sectional study.

Objectives: To identify disease activity scores and biomarkers that reflect magnetic resonance imaging (MRI)-determined sacroiliac joint (SIJ) inflammation in ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA).

Methods: Patients who had AS and nr-axSpA were enrolled. All the patients underwent SIJ MRI.

Melaleuca alternifolia (tea tree) oil and its monoterpene constituents in treating protozoan and helminthic infections.

Australian tea tree (Melaleuca alternifolia) oil (TTO) and its monoterpene constituents such as terpinen-4-ol (T4O), 1,8-cineole, limonene, p-cymene, and α-terpinene have been shown to be effective in controlling a wide range of parasitic infections. The anti-parasitic effects of these compounds are mainly due to their anti-histamine and anti-acetylcholinesterase activities as well as their ability to modulate host inflammatory responses. This review attempts to summarize recent advances in the uses of TTO and its 15 major monoterpene constituents in treating parasitic infections in both humans and animals.

Artemisinin and its derivatives: a potential treatment for leukemia.

Artemisinin (ART) and its derivatives are one of the most important classes of antimalarial agents, originally derived from a Chinese medicinal plant called Artemisia annua L. Beyond their outstanding antimalarial and antischistosomal activities, ART and its derivatives also possess both in-vitro and in-vivo activities against various types of cancer. Their anticancer effects range from initiation of apoptotic cell death to inhibition of cancer proliferation, metastasis and angiogenesis, and even modulation of the cell signal transduction pathway.

Artemisinin and its derivatives in treating helminthic infections beyond schistosomiasis.

The World Health Organization estimated that more than 1.5 billion people are infected with soil-transmitted helminths globally, and foodborne trematodiases in humans cause ∼2 million life-years lost to disability and death worldwide every year. Investment in prevention, treatment, and awareness of helminth infections and discovery of new, safe, effective, and affordable anti-helminth drugs are urgently needed.
