Prevention of skin aging and its treatment is an emerging field for development of new formulations in cosmetics. Accordingly, plant extracts with antioxidant properties are beneficial cosmetic ingredients for this purpose. This study was aimed at developing a stable and easily manufactured emulgel including green tea extract and rose oil that is effective on the barrier function and hydration of the skin. An emulgel formulation containing 20 % green tea extract and 5 % rose oil was designed as a result of pre-formulation studies. Physicochemical characterization, in vitro stability studies, in vivo water content of the stratum corneum and transepidermal water loss studies were carried out afterwards. In vivo studies on ten female subjects were evaluated by using non-invasive skin bioengineering techniques. Finally, a cosmetically acceptable, stable and effective emulgel formulation for skin barrier function with good hydrating properties was obtained for skin hydration, protection and anti-aging purposes.

Background: The incidence of thyroid cancer has increased annually, but the risk factors for thyroid cancer are still unclear. In this umbrella review, we aimed to identify associations between nongenetic risk factors and thyroid cancer incidence, and assess the quality and validity of the evidence.
Methods: PubMed, Embase and the Cochrane Database of Systematic Reviews were searched to identify related meta-analyses or systematic reviews of epidemiological studies.

Besides classic illegal drugs, numerous designer drugs, also called new psychoactive substances (NPSs), are available on the global drug market. One of the biggest and fastest-growing substance classes comprises the synthetic cannabinoids. According to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), 254 out of 950 monitored substances belong to this group of NPS, with 9 new cannabinoids registered for the first time in 2023.

Hyperuricemia (HUA) is a metabolic disease characterized by disorders of uric acid synthesis and excretion. Theabrownin (TB), a macromolecular water-soluble pigment from black tea, can bring beneficial effects on human health. The effects and underlying molecular mechanisms of TB on HUA animals and patients are still unclear.
