Tick-borne infections are the most common vector-borne diseases in the USA. Ticks harbor and transmit several infections with Lyme disease being the most common tickborne infection in the US and Europe. Lack of awareness about tick populations, specific diagnostic tests, and overlapping signs and symptoms of tick-borne infections can often lead to misdiagnosis affecting treatment and the prevalence data reported especially for non-Lyme tick-borne infections.

Chalcone is an aromatic ketone that forms the central core of many important biological compounds. Chalcone derivatives show various biological activities, especially anti-inflammatory, antibacterial, antioxidant, and anticancer activities, and also inhibit melanoma cell growth. In this study, we synthesized chalcone compounds with -chalcone's chemical structure under microwave (MW) and microwave-ultrasound (MW-US) conditions and compared them to chalcones produced using the classical synthesis method.

Taxol is a compound with a rigid, tetracyclic structure of diterpene, which is characterized by significant antitumor properties. Firstly, Taxol has been isolated by extraction from the bark of the yew tree. However, the low level of availability obligated the researchers' world to uncover alternative techniques of Taxol obtainment.

In various industries, particularly in the chemical and pharmaceutical fields, Fourier transform infrared spectroscopy (FTIR) spectroscopy provides a unique capacity to detect and characterise complex chemicals while minimising environmental damage by minimal waste generation and reducing the need for extensive sample preparation or use of harmful reagents. This review showcases the versatility of and FTIR applications for substance identification, analysis, and dynamic monitoring. FTIR spectroscopy's accuracy in identifying impurities, monitoring crystallisation processes, and regulating medication release patterns improves product quality, safety, and efficacy.
