Aim: The aim of this study was to assess the efficacy of sealing bile ducts by determining the adhesive strength of 2 different sealing agents, i.e. a fibrinogen-coated collagen patch (TachoSil) and a liquid fibrin sealant (Tissucol), in an experimental partial liver resection model in pigs.
Methods: Pigs underwent laparotomy and partial resection of the left medial liver lobe. A 16-Ch silicon catheter was introduced into the common bile duct. Pigs were randomly assigned to 2 groups (n = 4 each). In group 1, TachoSil was applied on the resection surface, and in group 2 Tissucol was applied. After 2 h, pressure in the intrabiliary system was gradually increased.
Results: No significant differences in the hemostasis times between TachoSil and Tissucol were observed (210.0 +/- 12.9 vs. 208.8 +/- 14.2 s; p = 0.9506). The pressure that could be resisted with Tissucol was significantly lower compared to TachoSil (77.0 +/- 8.6 vs. 131.8 +/- 16.3 mm Hg; p = 0.0405).
Conclusions: The application of TachoSil on the resection surface is equally effective in obtaining hemostasis and in sealing of biliary ducts as Tissucol. The adhesive strength of TachoSil on the resection surface, however, is superior to Tissucol.

Natural materials with highly oriented heterogeneous structures are often lightweight but strong, stiff but tough and durable. Such an integration of diverse incompatible mechanical properties is highly desired for man-made materials, especially weak hydrogels which are lack of high-precision structural design. Herein, we demonstrate the fabrication of hierarchically aligned heterogeneous hydrogels consisting of a compactly crosslinked sheath and an aligned porous core with alignments of nanofibrils at multi-scales by a sequential self-assembly assisted salting out method.

Sustainable pavement is essential for country development, offering durable, environmentally friendly, and cost-effective infrastructure. For Malaysia, sustainable pavement supports Sustainable Development Goals (SDGs) 9 and 11 while addressing road deterioration caused by increasing traffic volumes and loads. This deterioration shortens pavement service life and necessitates frequent maintenance, driving the need for innovative solutions.

Statement Of Problem: Comprehensive data are needed on the performance of chemically activated, chairside hard reline materials when used with computer-aided design and computer-aided manufacturing (CAD-CAM) milled polymethyl methacrylate (PMMA) denture bases and conventionally processed bases. This lack of data affects decisions regarding the chairside reline material to be used for improving the fit and retention of relined complete dentures.
Purpose: The purpose of this in vitro study was to evaluate and compare the shear bond strength (SBS) of 3 chemically activated, chairside hard reline materials on CAD-CAM milled and conventional heat-polymerized PMMA denture bases.

Emergency bleeding presents significant challenges such as high blood flow and rapid hemorrhaging. However, many existing hemostatic bandages face limitations, including the uncontrolled release of hemostatic agents, insufficient mechanical strength, poor adhesion, and complex manufacturing processes. To address these limitations, we developed a multifunctional hydrogel bandage for emergency hemostasis using a one-pot synthesis method.

Objectives: To evaluate the shear bond strength (SBS) of universal cements (UCs) to dentin prepared with different diamond burs using various adhesive strategies.
Materials And Methods: One-hundred-twenty molars were prepared to expose the mid-coronal dentin. The teeth were divided into two groups according to diamond bur preparations: coarse and super-fine grit burs.
