Synchrophasor devices guarantee situation awareness for real-time monitoring and operational visibility of smart grid. With their widespread implementation,significant challenges have emerged, especially in communication, data quality and cybersecurity. The existing literature treats these challenges as separate problems,when in reality, they have a complex interplay. This paper conducts a comprehensive review of quality and cybersecurity challenges for synchrophasors, and identifies the interdependencies between them. It also summarizes different methods used to evaluate the dependency and surveys how quality checking methods can be used to detect potential cyberattacks.

Alzheimer’s disease (AD) is a neurodegenerative disease distinguished by progressive cognitive deterioration along with declining activities of daily living and behavioral changes. It is the commonest type of pre-senile and senile dementia. Many new therapeutic strategies have been developed in the last few years. We aimed at reviewing the evidence supporting these new therapeutic targets, including anti-amyloid and anti-Tau strategies. This review is focused on important future direction in investigation of potential therapeutic targets for AD drug discovery. Medical advances have improved treatment of many diseases but still there is a need to establish new tools for early diagnosis of AD. A thorough comprehensive understanding of the unexplored mechanism can ameliorate the diagnostic and therapeutic management of AD. There have been several disease-modifying therapeutic strategies for AD in the last few years and are presently at various phases of investigation. Few of them have shown promising results, but their safety and efficacy need to be further explored.

Objective: The main objective of this study is to evaluate the prevalence of HIV infection among the clients attending ICTC, Gauhati Medical College & Hospital, Guwahati, for a period of seven years, i.e., from April 2008 to March 2015. Material & Method: A total of 40,983 clients attended ICTC, Gauhati Medical College & Hospital from the year 2008 to 2015. Serum samples were collected after taking informed consent and pre-test counseling. In India for all ICTCs, NACO (National AIDS Control Organization), a national guidelines has been followed for HIV testing, reporting and release of results with post test counseling. Results: Of the total 40,983 clients tested for HIV infection, 1919 (4.68%) were found to be HIV seropositive. Seropositivity was higher in male clients i.e. 1314 (68.47%) than female i.e. 604 (31.47%) followed by transgender (TG), i.e., 1 (0.0005%). Heterosexual route of transmission was the major route seen in 1666 clients (86.81%). Maximum HIV seropositivity was in the age group of 45 - 49 years (43.62%). Conclusion: HIV prevalence of 4.68 % among the clients attending ICTC, Gauhati Medical College & Hospital, Guwahati, puts the spotlight on the HIV burden in this part of the country and suggests the need for the scaling up of focused prevention efforts in high-risk groups.
