Current Pandemic in the World: Monkeypox from Past to Present.

Monkeypox is a zoonotic viral infection that was first identified in humans in 1970 in the Democratic Republic of Congo. The cases seen again in early May 2022 have reached 78.000 as of today. On July 23, 2022, the World Health Organization decided that the monkeypox outbreak represents a public health emergency. For the early diagnosis and effective treatment of monkeypox, inter-individual transmission routes, disease symptoms, factors affecting the course of the disease, presence of another infection, prognosis, pharmacological agents used in the prophylactic treatment, and their effects, populations at risk, waste disposal protocol should be known. For this reason, our aim is to reveal the sources of transmission of the monkeypox virus from past to present, what are the signs and symptoms in patients after infection, ways of protection from the virus, the mutation status of the virus, and treatment approaches.

18ß-glycyrrhetinic acid attenuates global cerebral ischemia/reperfusion-induced cardiac damage in C57BL/J6 mice

Abstract The aim of the present study is to investigate the cardioprotective effects of 18ß-glycyrrhetinic acid (18ß -GA) against oxidative and histological damage caused by global cerebral ischemia/ reperfusion (I/R) in C57BL/J6 mice. All male mice (n:40) were randomly divided into four groups: (1) sham-operated (Sham), (2) I/R, (3) 18ß-GA, and (4) 18ß -GA+I/R. Ischemia was not applied to the sham and 18ß-GA groups. In the I/R group, the bilateral carotid arteries were clipped for 15 min to induce ischemia, and the mice were treated with the vehicle for 10 days. In the 18ß-GA group, the mice were given 18ß-GA (100 mg/kg) for 10 days following a median incision without carotid occlusion. In the 18ß-GA+I/R group, the ischemic procedure performed to the I/R model was applied to the animals and afterwards they were intraperitoneally (i.p.) treated with 18ß-GA (100 mg/kg) for 10 days. It was found that global cerebral I/R increased TBARS levels and decreased antioxidant parameters. The 18ß-GA treatment decreased the level of TBARS and increased GSH, GPx, CAT, SOD activities. Also, the control group cardiac tissue samples were observed to have a normal histological appearance with the Hematoxylin-Eosin staining method. Histopathological damage was observed in the heart tissue samples belonging to the I/R group. The 18ß-GA treatment ameliorates oxidative and histological injury in the heart tissue after global ischemia reperfusion, and may be a beneficial alternative treatment
