Abstract: Even today, cancer is one of the prominent leading causes of death worldwide. However, there are a couple of treatment options available for management, but the adverse effects are more prominent as compared to therapeutic effects. Therefore, there is a need to design some midway that may help to bypass the negative effects or lower their severity. Nanotechnology has addressed many issues, still many miles are needed to cover before reaching the center stage. The developed nanofor-mulations can target distant organs owing to their multifunctionality and targeting potential. Stimuli-responsive nanomedicine is one of the most exploited formulations. They can encapsulate and release the drugs for a higher period. However, they release a burst mechanism. The other nano-formulations contain dendrimers, micelles, and lipid-based nano-formulations that have been developed and eval-uated for their efficacy in cancer treatment. This review paper highlights some significant patents granted/applied in various patent offices around the globe to treat cancer using the nanotechnology. The Google Patent, United States Patent and Trademark Office (USPTO), Escapenet, and many oth-ers were used as the search engine for patent search, and data were collected and analyzed. They used these patented technologies for diagnostic and treatment options, enhancing the absorption, distribu-tion, metabolism, and excretion (ADME) profile of therapeutic molecules.

Alzheimer's disease (AD) is considered the sixth leading cause of death in elderly patients and is characterized by progressive neuronal degeneration and impairment in memory, language, etc. AD is characterized by the deposition of senile plaque, accumulation of fibrils, and neurofibrillary tangles (NFTs) which are responsible for neuronal degeneration. Amyloid-β (Aβ) plays a key role in the process of neuronal degeneration in the case of AD. It has been reported that Aβ is responsible for the production of reactive oxygen species (ROS), depletion of endogenous antioxidants, increase in intracellular Ca

In the light of thousands of infections and deaths, the World Health Organization (WHO) has declared the outbreak of coronavirus disease (COVID-19) a worldwide pandemic. It has spread to about 22 million people worldwide, with a total of 0.45 million expiries, limiting the movement of most people worldwide in the last 6 months. However, COVID-19 became the foremost health, economic, and humanitarian challenge of the twenty-first century. Measures intended to curb the pandemic of COVID-19 included travel bans, lockdowns, and social distances through shelter orders, which will further stop human activities suddenly and eventually impact the world and the national economy. The viral disease is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). After SARS-CoV-2 virus and Middle East respiratory syndrome (MERS)-related CoV, COVID-19 is the third most significant lethal disease to humans. According to WHO, COVID-19 mortality exceeded that of SARS and MERS since COVID-19 was declared an international public health emergency. Genetic sequencing has recently established that COVID-19 is close to SARS-CoV and bat coronavirus which has not yet been recognized as the key cause of this pandemic outbreak, its transmission, and human pathogen mechanism. This review focuses on a brief introduction of novel coronavirus pathogens, including coronavirus in humans and animals, its taxonomic classification, symptoms, pathogenicity, social impact, economic impact, and potential treatment therapy for COVID-19.
