Matrix metalloproteinase (MMP)-induced collagen degradation at the resin-dentin interface remains a significant challenge for maintaining the longevity of dental restorations. This study investigated the effects of epigallocatechin-3-gallate (EGCG), a potent MMP inhibitor, on dental adhesive curing efficiency when encapsulated in halloysite nanotubes (HNTs). EGCG-loaded HNTs were incorporated into a commercial dental adhesive (Adper Scotchbond Multi-Purpose) at 7.

Brain tumors present a significant global health challenge, and their early detection and accurate classification are crucial for effective treatment strategies. This study presents a novel approach combining a lightweight parallel depthwise separable convolutional neural network (PDSCNN) and a hybrid ridge regression extreme learning machine (RRELM) for accurately classifying four types of brain tumors (glioma, meningioma, no tumor, and pituitary) based on MRI images. The proposed approach enhances the visibility and clarity of tumor features in MRI images by employing contrast-limited adaptive histogram equalization (CLAHE).

Introduction And Importance: The curative options for locally advanced hepatocellular carcinomas involving the vessels are very limited. Ex vivo liver resection and auto transplantation (ERAT) is a novel surgical method, which has been used in the management of such complex liver space occupying lesions, which are rendered conventionally unresectable. This technique involves a complete hepatectomy, extracorporeal hepatic resection on the backbench, and then reimplantation of the remnant hepatic parenchyma.

Article Synopsis
  • The integration of CAD-CAM technology in restorative dentistry has changed the game by incorporating both additive and subtractive manufacturing techniques, yet questions about how print orientation affects the mechanical properties of 3D printed resin materials persist.
  • This study aimed to analyze how different print orientations and artificial aging impact the flexural strength (FS) and flexural modulus (FM) of selected 3D printed resins used for definitive and interim dental restorations.
  • Results showed that print orientation significantly affects FS and FM, with specimens printed at a 90-degree angle demonstrating better mechanical properties compared to other orientations, particularly among definitive resin materials.

The efficacy and osseointegration rate of an implant depend on its biocompatibility. Modern implantology seeks fast and reliable osseointegration, which is essential for clinical success. The objective of this research was to assess the osseointegration and biocompatibility of a titanium-titanium diboride composite (Ti-TiB) in rabbits in contrast to those of pure titanium (Ti).
