Int J Biol Macromol 2023; 242:124819.

Abstract
Due to its poor prognosis and propensity for metastasizing, colon cancer, a frequent cancer of the gastrointestinal system, has a high morbidity and mortality rate. However, the harsh physiological conditions of the gastrointestinal tract can cause the anti-cancer medicine bufadienolides (BU) to lose some of its structure, impairing its ability to fight cancer. In this study, pH-responsive bufadienolides nanocrystals decorated by chitosan quaternary ammonium salt (HE BU NCs) were successfully constructed by a solvent evaporation method to improve the bioavailability, release characteristics and intestinal transport ability of BU. In vitro, studies have shown that HE BU NCs could improve BU internalization, significantly induce apoptosis, decrease mitochondrial membrane potential, and increase ROS levels in tumour cells. In vivo, experiments showed that HE BU NCs effectively targeted intestinal sites, increased their retention time, and exerted antitumor activity through Caspase-3 and Bax/Bcl-2 ratio pathways. In conclusion, pH-responsive bufadienolides nanocrystals decorated by chitosan quaternary ammonium salt could protect bufadienolides from the destruction of an acidic environment, achieve synergistic release in the intestinal site, improve oral bioavailability, and ultimately exert anti-colon cancer effects, which is a promising strategy for the treatment of colon cancer.

Abstract
The poor solubility of numerous drugs pose a long-existing challenge to the researchers in the fields of pharmaceutics, bioengineering and biotechnology. Many "top-down" and "bottom-up" nano fabrication methods have been exploited to provide solutions for this issue. In this study, a combination strategy of top-down process (electrospinning) and bottom-up (self-emulsifying) was demonstrated to be useful for enhancing the dissolution of a typical poorly water-soluble anticancer model drug (paclitaxel, PTX). With polyvinylpyrrolidone (PVP K90) as the filament-forming matrix and drug carrier, polyoxyethylene castor oil (PCO) as emulsifier, and triglyceride (TG) as oil phase, Both a single-fluid blending process and a coaxial process were utilized to prepare medicated nanofibers. Scanning electron microscope and transmission electron microscope (TEM) results clearly demonstrated the morphology and inner structures of the nanofibers. The lipid nanoparticles of emulsions after self-emulsification were also assessed through TEM. The encapsulation efficiency (EE) and in vitro dissolution tests demonstrated that the cores-shell nanofibers could provide a better self-emulsifying process int terms of a higher EE and a better drug sustained release profile. Meanwhile, an increase of sheath fluid rate could benefit an even better results, suggesting a clear process-property-performance relationship. The protocols reported here pave anew way for effective oral delivery of poorly water-soluble drug.

Abstract
Genome-editing technology has enabled scientists to make changes in model organisms' DNA at the genomic level to get biotechnologically important products from them. Most commonly employed technologies for this purpose are transcription activator like effector nucleases (TALENs), homing-endonucleases or meganucleases, zinc finger nucleases (ZFNs), and clustered regularly interspaced short palindromic repeats (CRISPR) associated protein 9 (Cas9). Among these tools, CRISPR/Cas9 is most preferred because it's easy to use, has a small mutation rate, has great effectiveness, low cost of development, and decreased rate of advancement. CRISPR/Cas9 has a lot of applications in plants, animals, humans, and microbes. It also has applications in many fields such as horticulture, cancer, food biotechnology, and targeted human genome treatments. CRISPR technology has shown great potential for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic to provide early and easy detection methods, possible treatment, and vaccine development. In the present review, genome-editing tools with their basic assembly and features have been discussed. Exceptional notice has been paid to CRISPR technology on basis of its structure and significant applications in humans, plants, animals, and microbes such as bacteria, viruses, and fungi. The review has also shed a little light on current CRISPR challenges and future perspectives.
