Robot-assisted minimally invasive surgery is effective for operations in limited space. Enhancing safety based on automatic tracking of surgical instrument position to prevent inadvertent harmful events such as tissue perforation or instrument collisions could be a meaningful augmentation to current robotic surgical systems. A vision-based instrument tracking scheme as a core algorithm to implement such functions was developed in this study. An automatic tracking scheme is proposed as a chain of

Glomerulonephritis (GN) has been associated with many solid and hematologic malignancies. However, cancer prevalence at the time of GN diagnosis has been rarely examined. We aimed to evaluate the cancer prevalence in patients with GN at the time of kidney biopsy and to compare the results to those of the general population. A total of 1,155 patients who underwent kidney biopsy between 2003 and 2017 were included. We investigated patients diagnosed with cancer within one month of kidney biopsy. T

While extensive studies have elucidated the relationships between exposure to air pollution and chronic diseases, such as cardiovascular disorders and diabetes, the intricate effects on specific kidney diseases, notably primary glomerulonephritis (GN)—an immune-mediated kidney ailment—are less well understood. Considering the escalating incidence of GN and conspicuous lack of investigative focus on its association with air quality, investigation is dedicated to examining the long-term effects of

TTYH2 is a calcium-activated, inwardly rectifying anion channel that has been shown to be related to renal cancer and colon cancer. Based on the topological prediction, TTYH2 protein has five transmembrane domains with the extracellular N-terminus and the cytoplasmic C-terminus. In the present study, we identified a vesicle transport protein, β-COP, as a novel specific binding partner of TTYH2 by yeast two-hybrid screening using a human brain cDNA library with the C-terminal region of TTYH2 (TTY

This study highlights the potential of AI-based imaging for determining sodium intake in hospitalized patients.

The objective of this study was to describe the prevalence of the headache attributed to Temporomandibular disorder(TMD) symptoms and to investigate the relationships of headache and TMD. 66 patients seeking care for signs and symptoms of Temporomandibular disorders(TMD) and Orofacial pain in the department of oral medicine, Dental Hospital, Chosun University, from January, 2008 to June, 2008, were recruited. The obtained results were as follows : 1. A muscle and TMJ origin combined was the most

Robot-assisted cardiac surgeries are effective for operations in limited spaces. Enhancement in safety functions based on automatic tracking of surgical instrument position to prevent inadvertent harmful events as cardiac tissue perforation and instrument collisions can be meaningful augmentation to current robot surgery system. A vision based instrument tracking scheme as a core algorithm to implement such assistive functions has been developed in this study. Through a chain of computer vision

Greater progression of renal injury and higher mortality occurred in patients with C3D-GN than with C3ND-GN, along with pathologic differences in interstitial and mesangial changes.

Higher estimated glomerular filtration rate variability was associated with increased 10-year mortality in the general population. This variability was very small, but considering the patients' long-term prognoses, it was significant.

Hormones may be key factors driving cancer development, and epidemiological findings suggest that steroid hormones play a crucial role in ovarian tumorigenesis. We demonstrated that high glucocorticoid receptor (GR) expression is associated with a poor prognosis of epithelial ovarian cancer. Recent studies have shown that the GR affects β-arrestin expression, and vice versa. Hence, we assessed the clinical significance of β-arrestin expression in ovarian cancer and determined whether β-arrestin

The misuse and overtreatment of antibiotics in hospitalized patients with community-acquired pneumonia (CAP) can cause multi-drug resistance and worsen clinical outcomes. We aimed to analyze the trends and appropriateness of antibiotic changes in hospitalized patients with CAP and their impact on clinical outcomes. This retrospective study enrolled patients with CAP, aged > 18 years, admitted from January 2017 to December 2021 at Seoul National University Bundang Hospital, South Korea. We examin

Lichen planus is a common, chronic inflammatory disease of the skin and mucous membrane for which no precise causes have been confirmed. But it is often connected with infections. Helicobacter pylori (H. pylori) among various bacteria has been associated with the cause of gastritis, peptic ulcer and gastric cancer. Considering the similarities of histological features between gastric ulcer and oral ulcers, it is resonable to assume that H. pylori might also be involved in the development oral mu
