Dataset, including a photo-guide, of alien plants sold in traditional medicine markets and healthcare outlets in three South African cities, specifically by traders of Indian, West African, East African, and Chinese origin.

This dataset is a an inventory of 475 alien plant taxa (447 identified to species), including a photo-guide to 96 plants, mostly sold as traditional medicines in three South African cities by traders of South African, West African, East African, Indian and Chinese origin (Williams et al., 2021). The dataset also incorporates species documented in a literature survey of alien plants used for traditional medicines in South Africa.

Drug adulteration of food supplements: A threat to public health in the European Union?

Food supplements have been playing an increasingly important role in the consumers' awareness nowadays. They are widespread and - according to popular belief - healthier and safer than synthetic drugs. In the European Union (EU) food supplements are classified as foodstuffs and thus not subjected to any specific safety assessments prior to commercialisation.

Clinical aspects of phage therapy.

Phage therapy (PT) is a unique method of treatment of bacterial infections using bacteriophages (phages)-viruses that specifically kill bacteria, including their antibiotic-resistant strains. Over the last decade a marked increase in interest in the therapeutic use of phages has been observed, which has resulted from a substantial rise in the prevalence of antibiotic resistance of bacteria, coupled with an inadequate number of new antibiotics. The first, and so far the only, center of PT in the European Union is the Phage Therapy Unit (PTU) established at the Ludwik Hirszfeld Institute of Immunology and Experimental Therapy, Wrocław, Poland in 2005.

Multiple effects of theobromine on fetus development and postnatal status of the immune system.

Caffeine and its active derivative, theobromine, are probably the most frequently ingested pharmacologically active substances. Considering their uninhibited transport via the placental barrier as well as immature enzymatic activities and metabolic pathways in embryos and infants resulting in the longer half-life of methyloxanthines and their accumulation, unrestrained uptake of these substances might result in noticeably more pronounced biological effects during pregnancy and the postnatal period. Our previous studies have shown that methyloxanthines are significant inhibitors of angiogenic growth factors production and angiogenesis itself.

The development and validation of the HLPC method for morphine content determination in poppy straw.

The HPLC method for morphine content determination in poppy straw has heen developed and validated. The method validation involved reproducibility and the following parameters of accuracy: selectivity and specificity, linearity and limits of detection and determination, interferences and recovery. The method was used to determine the morphine content in plant resources classified by the Law on "Neutralization of drug abuse" as a intoxicating agent from group I-N, in the content range of 0.
