AIMS Compound MQA (1,5-O-dicaffeoyl-3-O-[4-malic acid methyl ester]-quinic acid) is a natural derivative of caffeoylquinic acid isolated from Arctium lappa L. roots. However, we know little about the effects of MQA on the central nervous system. This study aims to investigate the neuroprotective effects and underlying mechanisms of MQA against the(More)
Recently, the increasing demand for telemedicine services has raised interest in the use of medical image protection technology. Conventional block ciphers are poorly suited to image protection due to the size of image data and increasing demand for real-time teleradiology and other online telehealth applications. To meet this challenge, this paper presents(More)
A major cause of cerebral ischemia is overactivation of the N-methyl-D-aspartate receptors (NMDARs). Therefore, NMDAR antagonists are needed for the treatment of cerebral ischemia. In our research, KuB protected the SH-SY5Y cells against NMDA-induced injury, apoptosis, LDH release and MMP loss. In addition, KuB could decrease MDA levels while increasing SOD(More)
Oxidative stress has been confirmed as a contribution to the pathogenesis and pathophysiology of many neurological disorders such as Alzheimer’s disease and Parkinson’s disease. Caffeoylquinic acids (CQAs) are considered to have anti-oxidative stress ability in a previous study, but the structure–activity relationships (SARs) of CQAs in neuroprotective(More)
In this paper, we have proposed a new method to develop secure image-encryption techniques using a Chirikov Standard Map and Logistic Map. In this technique, a Chirikov standard map is used to shuffle the pixels of the image and hence creating the confusion. The 1D logistic map is further used to create diffusion in the image. Various test images are used(More)
