We'll come to digital India we the Indians are at the top position in internet usage at the same time India is ranked third among list of countries globally where most of the threats were detected &second globally when it comes to spam and phishing (misleading emails, weblink etc. A data breach is the planned or inadvertent disclosure of confidential information to unauthorized parties. The impact of cyber-attack on a Company is much higherthan the impact on an individual.Data leakage poses serious threats to companies, including significant reputational damage and financial losses. Day by day as the volume of data is growing exponentially and data breaches are happening more frequently than ever before, identifying and preventing data loss has become one of the most pressing security concerns for organizations. This review article helps to learn about company’s data leak threats, recent data breach incidents and its impact on reputed companies
Cellular injury, irrespective of causative agents, is associated with a change in the transmembrane potential for calcium with subsequent accumulations of calcium to intracellular domains. At this time however, the association of sulfur mustard (HD)-induced cytotoxicity and calcium metabolism remains at controversy. This study correlates the ultrastructural cytopathology, cytochemical localization and x-ray microanalysis of calcium in cultured cells exposed to HD in vitro.NG108-15 and HeLa cells, exposed to 300 and 500 ¼M HD respectively and harvested at 1 to 24h post exposure, were fixed in 1.6% formaldehyde and 2.5% glutaraldehyde for 3 h at 4°C and processed for routine ultrastructural evaluation. Replicate populations were cytochemically processed for precipitation of calcium by incubating in a medium of 2% potassium pyroantimonate and 1% osmium tetroxide for 90 min in the dark at 20°C. Cells were then placed in a secondary medium of 0.5% tannic acid for 15 min, rinsed in 1% sodium sulfate, dehydrated in graded ethanols and embedded in epoxy resin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
