Role of residual mandibular teeth after computer-assisted mandibular reconstruction using a fibular flap.

Background: Computer-assisted mandibular reconstruction after mandibulectomy enables accurate reconstruction of the occlusal positions between the maxilla and mandible. Understanding the remaining teeth condition is essential for sensory mastication in patients with numerous tooth loss. However, no studies have examined the dental status of the remaining mandible after computer-assisted mandibular reconstruction using a fibular flap.

Multiple Buttresses Reconstruction of Maxilla with Fibular Flap Using Computer-aided Design/Computer-aided Manufacturing after Maxillectomy.

Background: The maxilla comprises horizontal and vertical buttresses, each with specific functions, supporting various organs, such as the eyes, nose, and oral cavity. Notably, they combine to form a three-dimensional structure, which enables the buttresses to provide their inherent support strength. However, reconstructing the maxilla after maxillectomy by assembling new buttresses is challenging.

Cutaneous wound healing promoted by topical administration of heat-killed Lactobacillus plantarum KB131 and possible contribution of CARD9-mediated signaling.

Optimal conditions for wound healing require a smooth transition from the early stage of inflammation to proliferation, and during this time alternatively activated (M2) macrophages play a central role. Recently, heat-killed lactic acid bacteria (LAB), such as Lactobacillus plantarum (L. plantarum) have been reported as possible modulators affecting the immune responses in wound healing.

Biosynthesis of hydrazine from ammonium and hydroxylamine using an anaerobic ammonium oxidizing bacterium.

Objectives: To synthesize hydrazine (NH) from ammonium and hydroxylamine (NHOH) using an anaerobic ammonium oxidation (anammox) bacterium, Candidatus Kuenenia stuttgartiensis.

Results: K. stuttgartiensis cells were anoxically cultivated with the addition of ammonium (2 mM) and NHOH (1-100 mM) at pH 6-10.
