Augmentation reality technology offers virtual information in addition to that of the real environment and thus opens new possibilities in various fields. The medical applications of augmentation reality are generally concentrated on surgery types, including neurosurgery, laparoscopic surgery and plastic surgery. Augmentation reality technology is also widely used in medical education and training. In dentistry, oral and maxillofacial surgery is the primary area of use, where dental implant plac

Microtomographic techniques are widely used for studying the trabecular architectures in the orthopedics and elucidation of tooth micromorphology in the field of dentistry. Its application to assess the osseointegration of dental implants has been studied as a non-invasive method, contrary to several conventional methods. The aim of this study is to evaluate the possibility of microtomography as a tool for assessing osseointegration. Twenty-four titanium dental implants (3.75 mm in diameter and

In a previous study, the authors suggested that HA coating deposited on a machined surface by the IBAD method showed results comparable to or more favorable than the results obtained with a blasted surface. This study indicated that the HA coating produced by the IBAD method was also very effective on the aluminum oxide-blasted surface, as demonstrated by the early formation of osseointegration. Morphometric analysis by microtomography showed some promise in measuring the osseointegration rate.

Liver cirrhosis is a major cause of mortality and a common end of various progressive liver diseases. Since the effective treatment is currently limited to liver transplantation, stem cell-based therapy as an alternative has attracted interest due to promising results from preclinical and clinical studies. However, there is still much to be understood regarding the precise mechanisms of action. A number of stem cells from different origins have been employed for hepatic regeneration with differe

<b>Background:</b> Most patients with gastric cancer rapidly lose weight after gastrectomy. Therefore, analysis of the effect of body mass index (BMI) on patients with gastric cancer survival should include postoperative BMI and BMI loss and preoperative BMI. This retrospective cohort study analyzed the effect of three BMI variables and their interaction on long-term outcomes.<b>Methods:</b> Preoperative BMI analysis included 2,063 patients with gastric cancer who underwent curative gastrectomy

We conducted a case-control study to investigate whether vascular endothelial growth factor (VEGF 22578, 21154, 2634, and 936) and kinase insert domain containing receptor (KDR 2604(KDR , 1192(KDR , and 1719) ) polymorphisms are associated with moyamoya disease. Korean patients with moyamoya disease (n = 107, mean age, 20.9615.9 years; 66.4% female) and 243 healthy control subjects (mean age, 23.0616.1 years; 56.8% female) were included. The subjects were divided into pediatric and adult groups.

The He plasma treatments on PIM zirconia implants made the surface more hydrophilic and enhanced the osseointegration of the implants without changing the micro-topography.

It is concluded that the osseointegration of PIM zirconia implant is promising and PIM using roughened mold etching technique can produce substantially rough surfaces on zirconia implants.

Alzheimer's disease (AD), a progressive neurodegenerative disorder featuring memory loss and cognitive impairment, is caused by synaptic failure and the excessive accumulation of misfolded proteins. Many unsuccessful attempts have been made to develop new small molecules or antibodies to intervene in the disease's pathogenesis. Stem cell-based therapies cast a new hope for AD treatment as a replacement or regeneration strategy. The results from recent preclinical studies regarding stem cell-base

We demonstrate that image-guided insular surgery with safe and accurate depth electrode guidance results in an optimal outcome and complete resection of the insular cortex.

Postoperative muscle mass loss and surgery-induced sarcopenia are prognostic factors for survival in patients with GC. Impact of postoperative muscle mass loss and surgery-induced sarcopenia on survival outcomes is dependent on the sex.
