BACKGROUND Neuropathic pain caused by peripheral nerve injury is a chronic disorder that represents a significant clinical challenge because the pathological mechanisms have not been fully elucidated. Several studies have suggested the involvement of various sodium channels, including tetrodotoxin-resistant NaV1.8, in affected dorsal root ganglion (DRG)(More)
Wounds of the oral mucosa show faster closure with less scar formation than skin wounds in other areas. A differentially expressed cDNA, wound-inducible transcript 3.0 (wit3.0), was isolated from oral mucosal wound in rats (Sukotjo, C., Abanmy, A. A., Ogawa, T., and Nishimura, I. (2002) J. Dent. Res. 81, 229-235). The purpose of this study was to(More)
PURPOSE This study evaluated the biologic effect in vivo of hydroxyapatite (HA) nanoparticle surface modification on commercially pure titanium or titanium alloy (Ti-6Al-4V) implants. MATERIALS AND METHODS Miniature cylindric titanium and Ti-6Al-4V implants were pretreated with dual acid etching (DAE), and a subset was further modified with HA(More)
Wounds created in the oral cavity heal rapidly and leave minimal scarring. We have examined a role of a previously isolated cDNA from oral wounds encoding wound inducible transcript-3.0 (wit3.0), also known as fibroblast growth factor receptor 1 oncogene partner 2 (FGFR1OP2). FGFR1OP2/wit3.0 was highly expressed in oral wound fibroblasts without noticeable(More)
PURPOSE The patient population varies in nutritional deficiencies, which may confound the host response to biomaterials. The objective of this study was to evaluate the effect of a common deficiency of vitamin D on implant osseointegration in the rat model. MATERIALS AND METHODS Male Sprague-Dawley rats were maintained under the cessation of vitamin D(More)
Painful peripheral neuropathy is a significant clinical problem; however, its pathological mechanism and effective treatments remain elusive. Increased peripheral expression of tetrodotoxin-resistant voltage-gated sodium channel 1.8 (NaV1.8) has been shown to associate with chronic pain symptoms in humans and experimental animals. Sciatic nerve entrapment(More)
Wound closure and infection control are the primary goal of wound management. A variety of disinfectants and antimicrobial agents are widely available today and routinely achieve infection control. On the contrary, wound closure still remains a challenging goal. Cell adhesion, migration and contraction play significant roles in creating contractile force of(More)
BACKGROUND After dental extraction, the external surface of alveolar bone undergoes resorption at various rates, and a group of patients develop excessive jawbone atrophy. Oral mucosa overlying the atrophied jawbone is unusually thin; therefore, we have hypothesized that excessive jawbone atrophy may be associated with abnormal oral mucosa contraction.(More)
