The main aim of my review to discuss the most prominent nanocarrier, “Lipid-Polymer Hybrid Nanoparticle” (LPHNPs) that overcomes the limitation of lipid and polymeric nanoparticles. That consists of polymeric core and lipid outer layer. The polymeric core encapsulates both hydrophilic and hydrophobic drugs and lipid shell provides a coat that gives a barrier to prevent drug leakage and easily penetrate into the skin. The LPHNPs has significant application in drug delivery, drug targeting, cancer treatment, brain drug delivery, multiple drug delivery, delivery of diagnostic imaging agent and Small interfering Ribonucleic acid (siRNA). This session is based on literature information in which LPHNPs were prepared by Two-step and Single-step method. Most of the researcher use the Single-step method by emulsification solvent evaporation and Nanoprecipitation method that are easy to prepare LPHNPs. The Polylactic Glycolic acid (PLGA), Poly € caprolactone, Chitosan, Alginate, Dextron, Sodium Alginate, etc used as polymeric core and Stearic Acid, Palmitic Acid, Cetyl Alcohol, Behenol Alcohol, etc used as lipid core. All results were analyzed by us according to the literature and authors’ expertise. The drug release depends on diffusion processes, followed by erosion, then swelling of the matrix. The lipid shell provides a biocompatible shield that acts as the phospholipid bilayer of skin and easily penetrates into the skin. That also capable to deliver the multidrug and diagnostic imaging agent for the treatment of cancer. The Lipid-Polymer Hybrid Nanoparticles are the most prominent nanocarrier for drug delivery. That is capable to deliver both Hydrophilic and Lipophilic drugs and show high bioavailability.

Exposure to zero gravity causes many physiological changes which may result to affect the health of people involved in space travel. The current review summarizes current knowledge on the start and progression of space motion sickness, bone loss, muscle loss, cardiovascular disorders, respiratory problems, and neuronal and hormonal problems. Around 70% of astronauts suffer from space adaption syndrome, fluid changes, and head motions. It has also been suggested that otolith asymmetries and Coriolis cross-coupling stimulation are the main causes of space motion sickness. The findings reveal that space flight directly affects the body's normal functioning. Despite an intense training routine, a study of historical data from piloted flights discovered that slow degradation of bone and muscle tissue, along with fluid losses, can eventually lead to kidney stones, musculoskeletal problems, bone fractures, and even problems with other organs of the body. Due to such problems focus is given to curing these problems associated with space travel. Medicines that are used in space and medicinal plants like Spirulina, and Ginseng that are of use for the treatment of these problems associated with space travel are discussed along with the treatment options available for such problems in space and the cautions that must be followed. Also, the herbal medication that can be used in outer space is taken into account. The findings of this study state the necessary precaution that needs to be taken by astronauts in outer space and also provides information for future research to be done on solving these problems.
