The gelatin plasma substitute is often polydisperse and heterogenous, making it difficult to determine the elimination rate and half-life in the body. In this study, one method was developed based on quantitative determination of hydroxyproline derivatives. Two plasma substitutes were prepared by succinylation and genipin-crosslinking, respectively. After transfusion, the blood samples were hydrolyzed and derivatized, and then analyzed by HPLC. A two-phase exponential association equation was used for fitting the time-concentration curves. The results indicated that this method could be used for quantitative determination of gelatin in blood, and the pharmacokinetic parameters such as elimination rate and half-life.

This study aimed to evaluate the influence of indirect-plasma-treated water (IPTW) in the preparation of hydrogels. Three commonly used natural, biodegradable polymers with the ability to form gels were selected: gelatin, carrageenan, and sodium alginate. The pH, gelling temperature, texture profile, swelling degree, and color of hydrogels were evaluated, and the polymers were subjected to Fourier-transform infrared (FTIR) spectroscopy.

The objective of this study is to examine how plasma-activated water (PAW) affects the formation of complexes between wheat starch (WS) and lauric acid (LA) during extrusion. The findings from various analysis, including complexing index, X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, and differential scanning calorimetry, revealed that PAW promoted the formation of WS-LA complexes during extrusion, resulting in a better long-range and short-range ordered structure, as well as higher gelatinization enthalpy. Consequently, PAW led to lower solubility, swelling power, gel property, and rapidly digestible starch content but higher resistant starch content.

Postoperative wound healing has been extensively studied and well-documented. Gelatin sponges are commonly used in surgeries for blood absorption. If these sponges can also release drugs with anti-scarring and anti-inflammatory effects, they would significantly enhance wound healing.

Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal cancer. Paclitaxel (PTX), typically administered intravenously (IV) as chemotherapy, shows promise for triggering immunogenic cell death (ICD) and may serve as a potential immunotherapy. This study introduces an oral PTX delivery method using an enteric-coated gelatin capsule containing capric acid oil and an effervescent agent, optionally with decylamine-conjugated β-glucans (DA-βGlus).

Neurotensin (NT), a bioactive tridecapeptide aids in diabetic wound healing by modulating inflammation and angiogenesis. However, its rapid degradation in peptidase-rich wound environment (plasma half-life <2 min) limits its efficacy. To address this, neurotensin-conjugated polymeric porous microparticles (NT-PMP) were developed and loaded in gelatin (hydrogel 15% w/v) for topical application, enabling sustained NT release to enhance therapeutic outcomes.
