Purpose: To compare clinical and magnetic resonance imaging (MRI) outcomes after uterine artery embolization (UAE) with non spherical polyvinyl alcohol (nPVA) versus gelatin sponge particles.
Material And Methods: During ten months, from Jan 2011 to Oct 2011, 60 patients underwent UAE in a standardized manner. nPVA (n = 30) or gelatin sponge particles (n = 30) were used in all patients. Pelvic MRI and clinical symptoms were reviewed before and after the procedure. Changes in tumor, uterine volume and infarction rate of dominant tumor were assessed using MRI.
Result: At three months after embolization, the outcome data were collected. The improvement of the mean bleeding score was more pronounced with gelatin sponge particles than with nPVA particles (p = 0.035). The mean volume reduction rate and infarction rate of dominant fibroid were 47.9 ± 20.8%, 97.7 ± 5.2% and 60.2 ± 18.1, 96 ± 7.0% after UAE with nPVA compared to gelatin sponge particles, respectively.
Conclusion: This study showed the superiority of gelatin sponge particles over nPVA in terms of improvement of mean bleeding score and volume reduction rate of dominant fibroid at three months follow-up after UAE, although the infarction rate of dominant fibroid was similar across groups at three months.

In this work, a series of three-dimensional (3D) SERS substrate were successfully fabricated by assembling silver nanoparticles (AgNPs) onto a porous gelatin sponge (GS) for highly sensitive thiram residues detection in vegetables. These 3D micro-nanostructures could induce the sufficient surface plasmon resonance (SPR) effect of noble metals on their surface and achieve high enrichment of pollutant molecules. As crystal violet (CV) was used as a probe molecule, the lowest CV solution could be detected at 10 M, and the enhancement factor (EF) was calculated to be 9.

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.

Background: Osteoporosis, characterized by decreased bone mineral density due to an imbalance between osteoblast and osteoclast activity, poses significant challenges in bone healing, particularly in postmenopausal women. Current treatments, such as bisphosphonates, are effective but associated with adverse effects like medication-related osteonecrosis of the jaw, necessitating safer alternatives.
Methods: This study investigated the use of L-serine-incorporated gelatin sponges for bone regeneration in calvarial defects in an ovariectomized rat model of osteoporosis.

A 62-year-old man was referred to our hospital presenting with a sore throat, dyspnea, and cervical swelling. Initial precontrast CT scans revealed a cervical and mediastinal hematoma, along with a hemothorax. Further dynamic contrast-enhanced CT scans indicated contrast media extravasation dorsal to the right thyroid gland lobe, suggesting a rupture of the right inferior thyroid artery or a parathyroid adenoma.

Nasal packing is a critical procedure in postoperative care and trauma management aimed at controlling bleeding, providing structural support, and promoting tissue healing. However, conventional nasal packs often lead to discomfort, infection risks, and secondary tissue damage. To address these challenges, this study explores the potential use of biodegradable and biocompatible gelatin-carrageenan composite scaffolds as an alternative nasal packing material.
