We previously reported a blast coating method (BC method) as a new coating method of titanium (Ti) with apatite (AP) at room temperature. The BC method gives much stronger AP coating on the Ti surface compared with those obtained by other room temperature coating methods. However, no in vivo study has been made, so far, to evaluate the stability or the tissue response to the implant. As an initial step to evaluate the feasibility of the BC method, we evaluated the tissue response and stability of AP coated Ti implant prepared with the BC method (AP-BC implant) using rats as experimental animals. The AP coating adhered tightly to the Ti surface even after the implant procedure and throughout the experimental period up to six weeks post operation. AP-BC implant caused no inflammatory response, showed strong bone response and much better osteoconductivity compared with the pure Ti implant. The new bone formed on the surface of AP-BC implants was thinner compared with that formed on the surface of Ti implant. Therefore, the AP-BC implant has a good potential as an osteoconductive implant material.

This study aimed to determine if local injection of CXCL12 reduces sphincter fibrosis, restores sphincter muscle content, vascularization, and innervation, and recruits progenitor cells in a rabbit model of anal sphincter injury and incontinence. Adult female rabbits were assigned to 3 groups: uninjured/no treatment (control), injured/treated (treated), and injured/no treatment (untreated) (n=4 each). Injured groups were anesthetized and a section of external anal sphincter was removed at the 9:00 o'clock position.

A revolutionary transformation in biomedical imaging is unfolding with the advent of aggregation-induced emission luminogens (AIEgens). These cutting-edge molecules not only overcome the limitations of traditional fluorescent probes but also improve the boundaries of high-contrast imaging. Unlike conventional fluorophores suffering from aggregation-caused quenching, AIEgens exhibit enhanced luminescence when aggregated, enabling superior imaging performance.

Purpose: This study aimed to investigate the usefulness of ultrasound-guided core-needle biopsy (US-CNB) for diagnosing type 1 AIP and evaluate the radiological outcomes following steroid therapy.
Materials And Methods: From January 2017 to June 2023, patients with pathology results containing "lymphoplasmacytic infiltration" and "fibrosis" were enrolled. The detection rate of level 1 histology by International Consensus Diagnostic Criteria (ICDC) and the contribution of US-CNB were assessed.

is a prominent Gram-negative and encapsulated opportunistic pathogen that causes a multitude of infections such as severe respiratory and healthcare-associated infections. Despite the widespread anti-microbial resistance and the high mortality rate, currently, no clinically vaccine is approved for battling . To date, messenger RNA (mRNA) vaccine is one of the most advancing technologies and are extensively investigated for viral infection, while infrequently applied for prevention of bacterial infections.

Purpose Of Review: To evaluate the role of neuroimmune signalling pathways in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP).
Recent Findings: The sinonasal mucosa is densely infiltrated by immune cells and neuronal structures that share an intimate spatial relationship within tissue compartments. Together, such neuroimmune units play a critical role in airway defence and homeostatic function.
