Bioinformatics is a noteworthy in appreciative the composite mechanisms of the cell and it is very beneficial for biomedical investigators to examination the clinical samples. Bioinformatics includes the usage of methods comprising useful mathematics, computer science, informatics, artificial intelligence (AI), statistics, chemistry, and biochemistry to resolve biological difficulties frequently on the molecular level. Bioinformatics tools provide significant benefits for nutrition discovery agendas such as cost-saving, time-to-market, and in-sight. The practical feature of bioinformatics is to recognize the code of life that is to decode the evidence that exists in the nucleotide sequence. Chemo-informatics is the application of computer and informational methods to challenge chemical problems, which highlight the manipulation of chemical structural information. Bioinformatics having numerous applications such as molecular medicine, personalized medicine, preventive medicine, gene therapy, etc. Several software packages are significant and free, and secure by well-known organizations. These consist of databanks like ChEMBL and SwissSidechain, software tools like 3D visualization, UCSF Chimera, and provides platform for software designers fascinated in structural biology, SwissSimilarity for virtual screening, Swiss-Bioisostere for ligand design, SwissTarget.

In recent years, herbal drugs have flourished as the method of rehabilitation of choice in numerous parts of the world and most of populations consider them as alternative conventional medicaments. However, most of the herbal drugs show poor solubility and bioavailability, which ultimately leads to diminished efficacy and frequency of administration. Consequently, self-emulsifying drug delivery system has been highlighted for poor water-soluble herbal medicaments. Self-emulsifying drug delivery system is an isotropic mixture of phytoconstituents, oil, surfactant, and cosurfactant, and subsequent to oral administration spontaneously endures self-emulsification and forms without emulsion as soon as it comes in contact gastric fluid. Most of the researchers and industrialists are attracted towards this novel and emerging technology as it offers various advantages. The chapter focuses on the mechanism of self-emulsifying, benefits of herbal SEDDS, factors affecting herbal SEDDS with formulation and characterisation of it.

Omega-3 fatty acids are related to healthy aging all over life. A moment ago, from fish, source omega-3 fatty acids DHA and EPA have been related with fetal development in AD and cognition related problems. Nevertheless, since the human body does not effectively produce few omega-3 fatty acids, while obtaining from marine sources. The brain is extremely augmented with lipids bilayers. Therefore, it is accountable to undertaken that the combination of different fatty acids within brain ha importance for brain functioning, counting neuropsychiatric and cognition development. To know the special effects form fatty acids ingestion, we need to depend on the mutual evaluation of experimental studies, observations, and interventional studies. The brain is enriched with lipid bilayers of omega-3 fatty acid constituents like DHA and EPA may have lots of effects on the brain. The potential function of omega-3 fatty acid, DHA, and EPA in the inhibition of cognition degeneration including AD has involved key importance from the last few decades. Additionally, AD has delivered the utmost positive sign to backing the situation that inflammation gives to a neurodegenerative disorder. The main etiology of the AD is unidentified, but genetic and ecological parameters are supposed, like family history, poor lifestyle and poor diet, the existence of any chronic disease like cardiovascular disease, increased age, and diabetes. It is assumed 174that primarily, management or prevention of inflammation may delay the indications of AD. Normally, changes the brain physiology with increased aging, comprising reduction of elongated chain omega-3 fatty acids as well as the brain of AD patients have reduced the DHA presence. Provided supplementary DHA can decrease the indications of inflammations. The health-related benefits of omega-3 fatty acids are really appreciable. Presently, there is no evidence of maintenance or confirmation of that modifiable risk parameters like herbal medicines, nutritional supplements, modified diet, etc. are associated with reduced the risk factors of AD or the cognition failure. Even though, multiple studies are showing that lifestyle and diet-related parameters are the main risk factors for AD and cognition behavior. This chapter basically focused on the different functions of omega-3 fatty acids mainly DHA and EPA in different neurodegenerative diseases and disorders.
