Abstract
Nicotinic α7 receptors have been shown in a variety of studies with animal models to play important roles in diverse components of cognitive function, including learning, memory and attention. Mice with α7 receptor knockouts show impairments in memory. Selective α7 agonists significantly improve learning, memory and attention. α7 receptors in limbic structures such as the hippocampus and amygdala have been demonstrated to play critical roles in memory. Blockade of α7 receptors in these areas cause memory impairments. In the brains of people with schizophrenia α7 receptors are impaired. This may be related to pronounced cognitive impairments seen with schizophrenia. There has been a major effort to develop α7 nicotinic agonists for helping to reverse cognitive impairment. These receptors are a promising target for development of therapeutic treatments for a variety of diseases of cognitive impairment including Alzheimer’s disease, attention deficit hyperactivity disorder (ADHD) and schizophrenia.

Drug-Targeted Approach with Polymer Nanocomposites for Improved Therapeutics
Polymer nanocomposites have been recognized as an advanced and cutting-edge technique in drug targeting administration. These materials combine the unique features of nanoparticles with the adaptability of polymers to produce highly personalized drug administration devices. Integrating nanoparticles containing pharmaceuticals into a polymer matrix enables researchers to regulate the rates at ...read more
RNA Molecules in the Treatment of Human Diseases
Messenger and non-coding RNAs, including long and small transcripts, are mediators of gene expression. Gene expression at the RNA level shows significant aberrations in human diseases, including cancer, leukemia, lymphoma, cardiovascular diseases, and neurological disorders. Human transcripts serve either as biomarkers of diagnosis, prognosis, prediction of treatment response, and/or therapy ...read more
Therapeutic Chemical and RNA Design with Artificial Intelligence
Computer-Aided Drug Design (CADD) has emerged as a fundamental component of modern drug discovery. Molecular docking facilitates virtual screening on a large scale through structural simulations. However, traditional CADD approaches face significant limitations, as they can only screen known compounds from existing libraries. PubChem, as the most widely used chemical ...read more
