Abstract: Influenza virus causes high morbidity among the infected population annually and occasionally the spread of pandemics. Melaleuca alternifolia Concentrate (MAC) is an essential oil derived from a native Australian tea tree. Our aim was to investigate whether MAC has any in vitro inhibitory effect on influenza virus infection and what mechanism does the MAC use to fight the virus infection. In this study, the antiviral activity of MAC was examined by its inhibition of cytopathic effects. In silico prediction was performed to evaluate the interaction between MAC and the viral haemagglutinin. We found that when the influenza virus was incubated with 0.010% MAC for one hour, no cytopathic effect on MDCK cells was found after the virus infection and no immunofluorescence signal was detected in the host cells. Electron microscopy showed that the virus treated with MAC retained its structural integrity. By computational simulations, we found that terpinen-4-ol, which is the major bioactive component of MAC, could combine with the membrane fusion site of haemagglutinin. Thus, we proved that MAC could prevent influenza virus from entering the host cells by disturbing the normal viral membrane fusion procedure.

The effect of TTO on acidification of cellular lysosomes was studied by vital staining with acridine orange using bafilomycin A1 as positive control. The treatment of cells with 0.01% (v/v) of TTO at 37 °C for 4 h before staining inhibited the acridine orange accumulation in acid cytoplasmic vesicles, indicating that TTO could inhibit viral uncoating by an interference with acidification of intralysosomal compartment.
Additionally, the present study evaluated the antiviral activity of essential oil in aerosol form. Reasonably, the more effective TTO was used in such kind of evaluation. As was found in aerosol form, the TTO possessed the strong antiviral action as well as on the filter surface. The concentration of aerosolized virus in all experiments was kept at the maximum possible level, which was achieved by relatively high virus titer in the initial suspension prepared for aerosolization (∼107.5/mL). Use of heavily concentrated bioaerosol stream enabled acquisition of more than 103 virions by 1 mL of the collecting liquid (varied slightly in different experiments), which provides opportunities for evaluation of the process efficiency within three orders of magnitude, enabling to identify the inactivation efficiency at the level above 99.5%. These findings look very promising for the implementation of such aromatic substances in filtration applications to control the harmful bioaerosols, and further improvement of the indoor air quality. Such type of essential oils could be successfully utilized as effective disinfectant against of broad range of microorganisms as well in aerosol form as in form of filter coating substance.
Ever wonder how celebrities look as if they are frozen in time? As if they don’t get old at all? Now a days, most celebrities are using laser, Botox, and many other cosmetic procedures that cost a chunk on our pay checks. On the other hand, there are a lot of anti-aging products, but they are packed with tons of chemicals and you’re not even sure if they are safe or would work for you.

Molds. They are everywhere and we’re exposed to them every day. They come in different forms and colors like the black spots on your shower curtains, or the mildew on your bathroom and kitchen tiles, or the white patches on walls and floors, or the invisible toxic mold in the air.
Molds grow in warm, dark and moist environment. Where there is moisture problem, there is mold. In fact, moisture is the key cause of mold growth. Air conditioners are only used intermittently. This allows moisture, dust and debris to collect in the air handler where molds can grow. As molds grow, its spores make their way in to the ducts system and front of the AC unit where they can be spread easily in the air and be inhaled by you or your family. That’s why it is very important to take immediate action to protect your family’s health.
