ABSTRACT

The most common route for drug administration is the oral route due to the various advantages offered by this route, such as ease of administration, controlled and sustained drug delivery, convenience, and non-invasiveness. In spite of this, oral drug absorption faces challenges due to various issues related to its stability, permeability and solubility in the GI tract. Biologic drugs generally face problems when administered by oral route as they are readily degradable and thus required to be injected. To overcome these issues in oral absorption, different approaches like novel drug delivery systems and newer pharmaceutical technologies have been adopted. With a combined knowledge of drug delivery and pharmaceutical technology, robotic pills can be designed and used successfully to enhance the adhesion and permeation of drugs through the mucus membrane of the GI tract to achieve drug delivery at the target site. The potential application of robotic pills in diagnosis and drug dispensing is also discussed. The review highlights recent developments in robotic pill drug-device technology and discusses its potential applications to solve the problems and challenges in oral drug delivery.

ABSTRACT

Chronic wound healing, especially in burns, is a major medical challenge with limited treatments. This study employs computational tools to identify phytomolecules that target multiple pathways involved in wound healing. By utilizing shape analysis, molecular docking, and binding energy calculations, potential compounds are pinpointed,to address the growing problem of chronic wounds. Initially, a set of phytomolecules from the ZINC database of natural molecules was screened to find compounds with shapes similar to well-known wound healing phytomolecules like curcumin, chromogenic acid, gallic acid, and quercetin. The most promising phytomolecules identified through shape similarity were further studied through molecular docking studies on several key targets involved in wound healing, including TNF-α, FGF, and TGF-ß. Among the tested phytomolecules, a ligand known as Fluorophenyl(5-(5-chloro-1-(2-fluorophenyl)-2-oxopentyl)-4,5,6,7-tetrahydrothieno[3,2c]pyridine-2-yl acetate) exhibited a strong affinity with favourable binding interactions for TNF-α ( - 7.1 kcal/mole), FGF (-6.9 kcal/mole), and TGF-ß (-5.1 kcal/mole). Another compound, 2,4 methoxybenzylidene-(-3)-oxo-2,3-dihydro-1-benzofuran-6-yl-4-methoxybenzoate, demonstrated a strong affinity with low binding energy for TNF-α ( - 6.8 kcal/mole) and FGF ( - 7.0 kcal/mole) targets. Isosakuranetin and Ermanin displayed moderate affinity for both TNF-α and FGF, with the highest affinity observed for the TGF-ß target. These findings suggest that these identified phytomolecules hold promise as potential lead compounds for further structural modifications, with the goal of designing new molecules that can target multiple pathways involved in the wound healing process.

ABSTRACT

Numerous scientific and medical domains have been revolutionized by nanotechnology, opening up unprecedented opportunities for healthcare applications. Among these developments, the creation of nanorobots for artificial blood components is a novel field of research that seeks to overcome the constraints of conventional pharmacological therapy. This review article provides a comprehensive overview of the nanorobotic artificial blood components and their therapeutic uses. The article begins by outlining the core concepts of nanotechnology and nanorobotic systems, emphasizing their design and control methods. It then delves into various types of nanorobotic artificial blood components, such as oxygen transporters (artificial RBCs), clotting agents (artificial platelets), and immune modulators (artificial WBCs). It goes into detail about their properties, functioning, and capabilities, which allow them to replicate the physiological activities of actual blood components. The article also assesses the clinical uses of artificial blood components in a variety of medical circumstances. It highlights their potential value in the management of certain blood-related diseases.

ABSTRACT

Non-alcoholic fatty liver disease (NAFLD) is a multifactorial complicated condition, reflected by the accumulation of extra fat in the liver. A detailed study of literature throws light on the fascinating connection between gut dysbiosis and NAFLD. The term 'gut dysbiosis' describes an imbalance in the harmony and operation of the gut microflora, which can upshoot a number of metabolic disorders. To recognize the underlying mechanisms and determine treatment options, it is essential to comprehend the connection between gut dysbiosis and NAFLD. This in-depth review discusses the normal gut microflora composition and its role in health, alterations in the gut microflora composition that leads to disease state focusing on NAFLD. The potential mechanisms influencing the advent and aggravation of NAFLD suggested disturbance of microbial metabolites, changes in gut barrier integrity, and imbalances in the composition of the gut microflora. Furthermore, it was discovered that gut dysbiosis affected immune responses, liver inflammation, and metabolic pathways, aggravating NAFLD.
