An Overview on Niosomes: A Drug Nanocarrier:(DDIPIJ)- Lupine Publishers



Niosome are non-ionic surfactant vesicles acquired on hydration of synthetic nonionic surfactants, with or without consolidation of cholesterol or their lipids. They are vesicular systems like liposome’s that can be utilized as transporters of amphiphilic and lipophilic medications. Niosomes are promising vehicle for drug delivery and being non-ionic; and Niosomes are biodegradable, biocompatible non immunogenic and show adaptability and flexibility in their structural characterization. Niosomes have been generally assessed for controlled discharge and targeted delivery for the treatment of tumor, viral infections and other microbial illnesses. Niosomes can entangle both hydrophilic and lipophilic medications and can prolong the circulation of the entrapped medication in body. Encapsulation of medication in vesicular system can be anticipated to delay the presence of medication in the systemic circulation and enhance penetration into target tissue, maybe decrease toxicity if specific take-up can be accomplished. This review focuses on components of niosomes, types, the advantages, preparation methods, factors affecting, characterizations, and applications of noisome.

Semiconductor Quantum Dots as In-Vivo Imaging Agent:(DDIPIJ)- Lupine Publishers



Inability to early diagnosis is a major concern for the treatment of fatal disease like cancer. Early diagnosis and treatment enhances the scope of disease curability. The accurate identification, realtime monitoring and targeting the cancerous tissues in a precise manner hold the key for longer progression free survival of a patient. Among different diagnostic techniques, fluorescence based minimally invasive bio-imaging techniques are considered to be ideal to have clear understanding about the physiological processes of the infected tissues as well as to reduce physical and mental stress of a patient. Super-resolution fluorescence microscopy has improved the spatial optical resolution of biological molecules, living cells and tissues with the use of highly fluorescent inorganic semiconductor nanocrystals, also known as quantum dots (QDs), with sizes ranging from 2 nm to 15 nm [1]. These nanocrystals comprised of elements belong to groups II–VI (eg, CdSe and CdTe), groups III–V (eg, InP), groups IV–VI (eg, PbS and PbSe) [2].

Intrinsically Disordered Proteins (IDPs): Experimental and Computational Approaches in Drug Discovery:(DDIPIJ)- Lupine Publishers



Intrinsically disordered proteins (IDPs) are proteins that usually do not adopt well-defined native structures when isolated in solution under physiological conditions. Numerous IDPs have close relationships with human diseases such as Parkinson disease, Alzheimer disease, diabetes, and so on. Recently IDPs are getting importance as desirable drug targets for major diseases. This review introduces IDP’s in drug discovery by experimental and by computational approach.

Antioxidant Properties and Antibacterial Activities of Leptadenia hastata Leaves Extracts on Staphylococcus aureus: (DDIPIJ)- Lupine Publishers



Leptadenia hastata extracts were evaluated for antibacterial activity and antioxidant properties. The leaf of the plant was extracted with n-hexane, dichloromethane, ethyl acetate, chloroform and methanol to give respective extracts. The Antibacterial activity against Staphylococcus aureus, was determined by disc diffusion method. Antioxidant activity was assayed by the DPPH radical scavenging activity mechanism. The results showed that of n-hexane, ethyl acetate, dichloromethane, chloroform and methanol extracts of Leptadenia hastata, methanol extract and chloroform extracts displayed more activity with 1.10 ± 0.10ab and 0.97 ± 0.06ab than others at 25-1000ppm/desk of the extracts tested. The most antioxidant activities against DPPH were displayed by the hexane and methanol extracts of Leptadenia hastata leaf, exhibiting IC50 (63.44μg/mL) and IC50 (46.80μg/mL) respectively, followed by chloroform, dichloromethane and lastly ethyl acetate crude extract. The present results showed potential of the medicinal plant used by traditional herbal medical practitioners as natural anti-microbial, antioxidant and potentially antiinflammatory agents. The results confirm that Leptadenia hastata leaves extracts can be used as a source of drugs to fight infections caused by susceptible bacteria.

Preparatory Preparations for the Study of Drug Therapies for Emergency Diseases:(DDIPIJ)- Lupine Publishers



In the US, more than 400,000 medical treatments are carried out each year to eliminate intestinal adhesion. The economic loss from these medical treatments is estimated to be about $1.2 billion. This economic loss has been significant, and the search results from pub med under keyword Intestinal Obstruction have been decreasing since 2015. It is difficult to research and prevent a disease caused by small intestine, which is one of the emergency diseases. Because emergency diseases have structural problems that are very difficult to collect and analyze data for research. Emergency care measures, especially drug development, require a platform that allows public funding and sharing of clinical data. Emergency diseases have scattered clinical data. The research into this emergency disease requires a method of receiving clinical data as a condition to provide free medical treatment to patients through the IRB. There is an urgent need to find the reverse data. Modern society is a time of the Fourth Industrial Revolution. Above all, AI, Deep Learning, and platforms are important keywords. In these times, open and international cooperation is necessary for the safety of emergency patients such as intestinal obstruction. Development guidelines describe how medicine will overcome these shortcomings during the Fourth Industrial Revolution.
