With the rapid development of the Internet and computational technologies, the exponential growth of digital data is beginning to overwhelm existing storage device capacities, driving an unprecedented demand for new data storage media. DNA, a natural genetic information storage system, has been proposed as a promising alternative[1]. Compared with traditional siliconbased storage, DNA-based storage hasmany advantages—incredible density,

Dear editor, Security experts have been fighting against cybercriminals for many years and existing research shows that this battle will continue. Malicious software has no remorse when it targets different organizations, regardless of its forms [1]. Ransomware [2] has caused serious issues in different industries, especially in healthcare. The existing report shows that 34% of ransomware is targeting healthcare organizations. Nowadays, criminals prefer crypto-jacking over ransomware (which also relies on cryptocurrency for anonymous ransom payments).

Objectives： The aim of this study is to evaluate the hepatoprotective effect of Lasianthera africana （lcacinaceae） against isoniazid （INH） and rifampicin （RlF）-induced liver damage in rats. Methods： The hepatoprotective effects of hot aqueous L. africana （HALA） leaf extract （0.1-1 g/kg） and sily-matin （50 mg/kg） were assessed in a model of oxidative liver damage induced by RIF and INH （100 mg/kg each） in Wistar rats for 28 days. Biochemical markers of hepatic damage such as alanine aminotrans- ferase （ALT）, aspartate aminotransferase （AST） and alkaline phosphatase （ALP） were assessed. The antiox- idant statuses of plasma glutathione peroxidase （GSPx）, glutathione reductase （GSH）, catalase （CAT） and superoxide dismutase （SOD） and lipid peroxidation were evaluated. Results： The pretreatment of INH and RIF decreased hematological indices and the antioxidant levels （P〈 0.001） and increased the levels of liver marker enzymes （P〈 0.001）. However, pretreatment with HALA extract and silymarin provoked significant elevation of hematological indices. The levels of AST, ALT, and ALP were depressed （P 〈 0.001 ）. Total triglycerides, total cholesterol, total bilirubin and low-density lipoprotein were decreased （P 〈 0.001）. However, high-density lipoprotein, bicarbonate, and electrolytes like chloride and potassium were elevated （P 〈 0.001）, but sodium was depressed （P 〈 0.05）. Additionally, GSH, GSPx, SOD and CAT were elevated （P 〈 0.01） and malondialdehyde was depressed （P 〈 0.001 ） when compared to the R1F-INH-treated rats. Histopathological evaluations support hepatoprotective activity. Conclusion： This study demonstrated that HALA leaf extract attenuated RIF-INH-induced hepatotoxicity. L, africana could be exploited in management of RIF-INH-induced hepatitis.
