Over the past few decades, anthropogenic activities contributed to the depletion of the ozone layer, which increased the levels of solar ultraviolet-B (UV-B) radiation reaching the Earth`s surface. Generally, UV-B is harmful to all living organisms. It damages the cell`s Deoxyribonucleic acid (DNA), proteins, and lipids, and as a consequence, it affects the bio-membranes negatively. In this review, we summarize the major effects of UV-B in the plant`s main molecules and physiological reactions, in addition to the possible defence mechanisms against UV-B including accumulating UV-B absorbing pigments to alleviate the harmful impact of UV-B.

Monkeypox is a zoonotic disease caused by the monkeypox virus of the genus Orthopoxvirus genus and Poxiviridae family. Many animal species, including rodents and monkeys, can transmit the virus. However, the natural reservoir is unknown yet. It can be transmitted to humans via close contact with infected animal or person, or contaminated materials. Monkeypox virus was first detected in 1958 among cynomolgus monkey's colony in Denmark. The first human case of monkeypox was reported in September 1970 in a 9-month-old child with smallpox-like vesicular skin lesions. This virus usually affects humans and animals living in Central and West Africa, yet it led to several outbreaks previously out of Africa since its discovery. Since 7 May 2022, monkeypox started to appear again in non-endemic countries. By 29 July 2022 at 9:00 PM (GMT), 22485 confirmed cases were recorded worldwide. This review focuses on monkeypox virus structure, transmission, symptoms, diagnosis methods, treatment and prevention.
