Personalized and Precision Medicine Journal

Abstract Alzheimer's disease (AD) is a neurodegenerative disease that leads to progressive and incurable cognitive and behavioral disorders. Personalized medicine, which is also called precision medicine, represents an approach to the treatment of the disease with the aim of improving the effectiveness of the treatment, which stops or slows the disease in an optimal and targeted manner based on a certain time. It enables physician to accurately and efficiently identify the most effective treatment. Personalized medicine is based on molecular knowledge. Genome sequencing by the Human Genome Project (HGP) represents one of the most powerful tools for personalized medicine, as well as transcriptomics, proteomics and metabolomics development which can be used for both disease prediction and better treatment. In this paper, we will review the strategies that personalized medicine offers for the treatment of AD for the future.

Abstract Personalized medicine is the clinical treatment of diseases that is tailored to the physiologic, molecular genetics and lifestyle characteristics of the patient.
Personalized medicine can be considered as a new approach to face diseases and develop traditional methods for their diagnosis and treatment. This novel field of medicine has the potential of changing identification and management of health problems strategies. Corona virus disease 2019 (COVID-19) is an infectious disease that affects the lungs of patients. This novel outbreak was first reported on 31 December 2019 in Wuhan, the capital of Hubei province of China, and it had many effects on people's lives all over the world in various economic, social and health fields until now. Since the start of the pandemic Covid-19, the World Health Organization (WHO) has expressed concern about the public health emergency. Although the disease has mild symptoms and similar to a common cold in most people, in some cases it can lead to pneumonia, acute respiratory distress syndrome, multi-organ dysfunction, and even death. Therefore, due to the different effects of this disease in individuals and even families, the role of personalized medicine becomes more significant and sensitive. Considering the rapid spread and global crisis of Covid-19, recent research has focused more on the control and treatment of the virus. The main goal of this paper is the investigation of different effects of the virus on patients and study of the personalized medicine roles in the control and treatment of the disease.

Abstract Personalized medicine as a revolutionary in medicine provides medical services tailored to a person's molecular characteristics. In personalized medicine, the physician with the knowledge of information in the person’s molecular profile (omics) can prescribe an effective drug with minimal side effects and appropriate dose for changing lifestyle and diet to prevent and treat diseases.
Theoretically, the molecular profile of each individual could give some information about risk of diseases, the person responses to medications and the relationship between person molecular profile and certain traits, such as lactose intolerance and diet-specific adaptation.
In the past, it was impossible to confirm the presence or absence of mutations in an individual's genome, as the use of molecular techniques such as PCR was very time consuming and was associated with many limitations. On the other hand, many traits and diseases are multigenic and the consequence of interaction with environment. Furthermore mathematical models for measuring genetic risk were not developed.
In recent years, creation of individual genetic profile with determination of a person's genotype and all known mutations in a short time and at low cost became possible, due to advances in microarray technology, computer science and statistics.
In parallel with genomics, advances in other multidisciplinary sciences such as nanotechnology and systematic biology have facilitated the disease interactions at the cellular and molecular scale. Nanomedicine has provided the control of drug release profiles using design and fabrication of nanostructured devices, so it is hoped that by combining these information and examining their interactions, better contribution to human health will be achieved. In this review, we focused on nanotechnology applications and solutions that impact on personalized medicine and accelerate its progress and development.
