Article Abstract
The analysis aimed to prepare an in-situ implant (ISFI) formulation holding dimethyl fumarate as (a model drug) using cross-linked gellan gum by homogenization method. Cross-linking of gellan gum was done with L-cysteine to improve its gelation properties. Fourier transform infrared spectroscopy (FTIR) and (DSC) Differential scanning calorimetry were used to test the compatibility of the drug-polymer. The diverse formulations were prepared and tested using Design Expert® ver 8.0.1 software to optimize the experiment technique and employ the response surface. The tissue compatibility of the test verified the existence of non-irritants in the established formulation. All preparations contained the drug content from approximately 97.98 to 99.88%. Viscosities are ideal for injection in the optimized formulation (1,55 percent w/w in water). The optimized formula was monitored, and up to 156hours, it was found to be 95.7%. The result was that ISFI can effectively monitor and control the delivery of several powerful drug products.

Polysaccharide copolymers Conjuates have surfaced as a versatile foundation in the development of advanced smart drug delivery systems, owing to their inherent biocompatibility, biodegradability, and capacity for chemical modification. This review brings into focus the recent advances in co-polymeric drug delivery systems based on naturally occurring polysaccharides like chitosan, alginate, dextran, hyaluronic acid, pullulan, guar gum, xanthan gum, agarose, gellan gum, and starch. Their structural malleability and functionalization capabilities are emphasized to engineer therapeutic payload stability, bioavailability, and controlled release.

Northern Shaanxi's oil-gas drilling produces large amounts of waste drilling fluids with high-value solids (barite, bentonite). Traditional disposal causes resource waste and pollution. This study proposes a stepwise flotation process for typical local oil-based waste: surface cleaning to break oil film wrapping and combined reagents to regulate mineral surface hydrophobicity differences, enabling efficient separation and recovery of barite and bentonite.

Various dressings have been developed for the prevention and treatment of wound infections, but the complex structures and manufacturing processes designed to achieve powerful functionalities have impeded their clinical application. Herein, a dynamic injectable photothermal/chemotherapeutic hydrogel has been facilely established through mixing gellan gum (GG), indocyanine green (ICG) and amikacin (AMI) aqueous solutions at 80°C and cooling to room temperature. The hydrogel displayed a precise structure with 1.

Notoginsenoside Rb1 (Rb1), a bioactive saponin from exerts cardio-cerebrovascular protective, anti-inflammatory, antioxidant, and glucose homeostasis-regulating effects. However, its oral bioavailability is limited by gastric degradation and poor intestinal permeability. This study presents a food-grade bigel system for encapsulating Rb1 to enhance its stability and controlled-release performance.
