It also presents key steps and parameters implemented for clinical success. Finally, we analyse, discuss, and provide clinical perspectives on the integrated opportunities of nanotechnology and immunology to achieve synergistic and durable responses in cancer treatment.In vivo evaluation of arabinoxylans (AX) microspheres showed to protect insulin from degradation in the upper gastrointestinal tract and carrier insulin to colon. Insulin-loaded AX microspheres (50 UI/kg) decreased blood glucose level by 39% in diabetic rats with a maximum effect at 18 h post-administration, indicating that insulin remains bioactive. The continuous administration (4 days) of insulin-loaded AX microspheres improved the polyuria and increased the production of short-chain fatty acids, as well as Bifidobacterium and Bacteroides in diabetic rats compared to untreated diabetic rats. AX microspheres are a potential microbiota-activated carrier for colon-specific drug delivery and could be useful as a complementary treatment for diabetes.The present investigation explores the potential of novel dual drug-loaded niosomes for nasal delivery of Rivastigmine (RIV) and N-Acetyl Cysteine (NAC) to the brain. The dual niosomes showed a particle size of 162.4 nm and % entrapment efficiencies of 97.7% for RIV and 85.9% for NAC. The niosomes were statistically validated using Box-Behnken experimental design (BBD) with good significance. Ultrastructural and chemical characterization of the niosomes using various analytical techniques like Fourier Transform Infrared spectroscopy (FTIR), Differential scanning calorimetry (DSC), Transmission electron microscopy (TEM) showcased drug-excipient compatibility and robust stability of 6 months in a liquid state at 4-8 °C. The dual drug-loaded niosomes showed a sustained drug release pattern up to 2 days. Acetylcholinesterase (AChE) and DPPH (1, 1-diphenyl-2- picrylhydrazyl) enzyme inhibition assays showed a better combinative effect than the free drug solutions. A 2-day nasal permeation proved the effectiveness and biocompatibility of the niosomes. In-vivo pharmacokinetic and organ biodistribution studies revealed a better drug profile and greater distribution of the niosomes in the brain compared to other organs, thereby indicating a direct nose-to-brain delivery of the niosomes.Congenital long QT syndrome [LQTS] is a channelopathy characterized by QT prolongation and polymorphic VT. LQTS however need not be a purely electrical disease. Defects in ion channels may cause myocardial architectural disruption leading to ventricular non compaction [VNC]. It is defined as the presence of prominent ventricular trabeculations and deep intertrabecular recesses within the endomyocardium. We describe the in-utero management of a foetus who was later found to have LQTS with VNC. The detection of ventricular tachycardia and complete heart block in utero should arouse the suspicion of LQTS. It would be wise to avoid QT prolonging antiarrhythmics in this subset of patients.The emergence of a clustered regularly interspaced short palindromic repeats/CRISPR-associated proteins (CRISPR/Cas) system has had a revolutionary impact on plant biology. However, this system and further developed base editing are limited by their inherent imperfection. Prime editing, a just arrival technology based on CRISPR/Cas, can directly and precisely edit a specified DNA site without double strand breaks and donor DNA by integrating an engineered reverse transcriptase (RT) with a catalytically impaired Cas9 endonuclease and introducing genetic information into prime editing guide RNA (pegRNA). In addition, it has a wider range of editing types than base editing and can install all types of editing theoretically. Prime editing was originally developed in mammalian cells and has recently been applied to plants. Here, we describe the origin of prime editing and compare it with traditional CRISPR/Cas9 and base editing; then, we exemplify it in plants, including strategies and methods. Accordingly, we generate the overall procedures of prime editing to provide instructions for its application. Furthermore, we summarize its improvements in the approach, such as optimizing the length of a primer binding site and RT template, as well as pursuing an optimal nicking site in the unedited sequence. Finally, we discuss the potential impact on domestication and improvement of agricultural crops, sustainable utilization of medicinal plants, cultivation of varieties of horticultural plants, and revelation of the genetic code, in order to offer a reference for the further study and development of prime editing.The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based base editors have been developed for precisely installing point mutations in genomes with high efficiency. Two editing systems of cytosine base editors (CBEs) and adenine base editors (ABEs) have been developed for conversion of C.G-to-T.A and A.T-to-G.C, respectively, showing the prominence in genomic DNA correction and mutation. Here, we summarize recent optimized approaches in improving base editors, including the evolution of Cas proteins, the choice of deamination enzymes, modification on linker length, base-editor expression, and addition of functional domains. Specifically, in this paper we highlight a strategy of split-intein mediated base-editor reconstitution for its adeno-associated virus (AAV) delivery. DiR chemical order The purpose of this article is to offer readers with a better understanding of AAV-mediated base editors, and facilitate them to use this tool in in vivo experiments and potential clinical applications.Base editing technology is an efficient tool for genome editing, particularly in the correction of base mutations. Diverse base editing systems were developed according to the dCas9 or nCas9 linked with different deaminase or reverse transcriptase in the editors, including ABEs, CBEs, PEs and dual-functional of base editor (such as CGBE1, A&C-BEmax, ACBE, etc.). Currently, Base editing technology has been widely applied to various fields such as microorganisms, plants, animals and medicine for basic research and therapeutics. Here, we reviewed the advancement of base editing technology. We also discussed the application of base editors in different areas in the future.
