Association between dental scaling and metabolic syndrome and lifestyle.

Purpose: Periodontal disease is a risk factor for diabetes and metabolic syndrome, and non-surgical periodontal treatment has been shown to help maintain stable blood sugar in diabetic patients. Determining the level of preventive scaling in patients with metabolic syndrome will help manage the disease. The purpose of this study was to investigate the extent to which people with metabolic syndrome or bad lifestyle performed scaling and the association between preventive scaling and metabolic syndrome or lifestyle in a large population.

Development of a semi-open chamber system for the gas exchange measurement of whole-canopy under steady and unsteady states in cucumber seedlings.

Background: Large-scale data on the photosynthetic characteristics of whole crop canopy is crucial for improving yield. However, current data collection methods remain challenging, and the time constraints associated with photosynthetic data collection further complicate matters. Developing a practical yet easy-to-use tool for collecting whole-canopy data is essential to address these challenges.

Pulp and periapical disease as a risk factor for osteonecrosis of the jaw: a national cohort-based study in Korea.

Purpose: This longitudinal cohort study aimed to evaluate the relationship between osteonecrosis of the jaw and pulp and periapical disease in patients who were administered bisphosphonates.

Methods: Using data from a nationwide cohort, we examined the association among dental caries, pulp and periapical disease, and osteonecrosis of the jaw in women aged >50 years who received bisphosphonates for more than 1 year between 2002 and 2015. Because of ambiguities in the diagnosis of osteonecrosis of the jaw in population-based data, we operationally defined and categorized the condition into established and potential osteonecrosis of the jaw.

The practicality of interleukin-6 in prognosis of blunt chest trauma in Korea: a retrospective study.

Purpose: There are many studies on the practicality of interleukin-6 (IL-6) as a prognostic predictor in patients with multiple severe traumas. However, few studies focus on the practicality of IL-6 in patients with chest trauma. So, this study investigated whether IL-6 is effective as a prognostic factor in patients with blunt chest trauma.

No effect of desmopressin administration before kidney biopsy on the risk of major post-biopsy bleeding.

Background/aims: The most important complication of kidney biopsy is bleeding, and it is unclear whether desmopressin is effective in preventing it. Thus, the study was conducted to compare post-biopsy bleeding with or without desmopressin prescription prior to percutaneous kidney biopsy.

Methods: In this single-centered, retrospective, and observational study, 3,018 adult patients who underwent kidney biopsy between January 1, 2003 and March 31, 2019 at our institute were recruited.

Prevalence and risk factors of baclofen neurotoxicity in patients with severely impaired renal function.

Background/aims: The most common adverse effect of baclofen, used for managing hiccups and spasticity, is neurotoxicity. As baclofen is primarily excreted by the kidneys, neurotoxicity is more likely to occur in patients with chronic kidney disease (CKD). We evaluated the risk factor for baclofen neurotoxicity and the recommended dosage for patients with severe CKD.

Biventricular Takotsubo Cardiomyopathy Associated with Epilepsy.

We describe a case of Takotsubo cardiomyopathy in an elderly woman after status epilepticus. In an emergency echocardiography, not only left ventricular apical ballooning but also right ventricular apical hypokinesia was observed. After a medical management, the patient's condition was improved and a follow-up echocardiography showed substantial recovery of left and right ventricular apical ballooning.

External root resorption during orthodontic treatment in root-filled teeth and contralateral teeth with vital pulp: A clinical study of contributing factors.

Introduction: There is a lack of research to support the belief that root canal treatment can be considered for stopping or decreasing external apical root resorption (EARR). There is conflicting evidence as to whether root-filled teeth are more or less likely to experience EARR after orthodontic treatment. The purpose of this study was to compare the degree of EARR of root-filled teeth with that of contralateral teeth with vital pulp after fixed orthodontic treatment.

Guanidine modified polyethyleneimine-g-polyethylene glycol nanocarriers for long interfering RNA (liRNA) based advanced anticancer therapy.

Combination therapy involving the synergism between different therapeutic approaches seems to be a promising strategy in anticancer treatment. Immunostimulatory long interfering RNA (liRNA) structures capable of executing specific RNA interference (RNAi) mediated gene silencing tasks seem to be potential candidates for a combination approach. Apart from their therapeutic efficacy, the unique structural format of liRNA candidates facilitates better association with cationic polymers and significantly improves their intra-cellular delivery.

Efficient intracellular delivery and multiple-target gene silencing triggered by tripodal RNA based nanoparticles: a promising approach in liver-specific RNAi delivery.

RNA interference (RNAi) triggering oligonucleotides in unconventional structural format can offer advantages over conventional small interfering RNA (siRNA), enhanced cellular delivery and improved target gene silencing. With this concept, we present a well-defined tripodal-interfering RNA (tiRNA) structure that can induce simultaneous silencing of multiple target genes with improved potency. The tiRNA structure, formed by the complementary association of three single-stranded RNA units, was optimized for improved gene silencing efficacy.

Correlation analysis of three-dimensional changes of hard and soft tissues in class III orthognathic surgery patients using cone-beam computed tomography.

Background: This study was to investigate the correlation between changes of the soft and hard tissues three-dimensionally in class III orthognathic patients using cone-beam computed tomography.

Methods: Cone-beam computed tomography images were obtained within 2 weeks before surgery and at 6 months after surgery in 18 adult class III patients who underwent Le Fort I osteotomy and bilateral intraoral vertical ramus osteotomy. Subjects were divided into group 1 with no mandibular asymmetry (menton deviation, <2 mm; n = 9) and group 2 with mandibular asymmetry (menton deviation, >4 mm; n = 9).

Long dsRNA-mediated RNA interference and immunostimulation: a targeted delivery approach using polyethyleneimine based nano-carriers.

RNA oligonucleotides capable of inducing controlled immunostimulation combined with specific oncogene silencing via an RNA interference (RNAi) mechanism provide synergistic inhibition of cancer cell growth. With this concept, we previously designed a potent immunostimulatory long double stranded RNA, referred to as liRNA, capable of executing RNAi mediated specific target gene silencing. In this study, we developed a highly effective liRNA based targeted delivery system to apply in the treatment of glioblastoma multiforme.

Synchronous occurrence of primary malignant mixed müllerian tumor in ovary and uterus.

Malignant mixed müllerian tumor (MMMT) arising from female internal genitalia is rare with the uterine corpus being the most prevalently affected site. It is even more rare when it occurs on both uterus and ovary at the same time. We describe a case of synchronized occurrence of MMMT on ovary and uterine adenosarcoma with review of literature.

Promising treatment results of adjuvant chemotherapy following radical hysterectomy for intermediate risk stage 1B cervical cancer.

Objective: The aim of this retrospective study is to evaluate the efficacy of adjuvant chemotherapy following radical hysterectomy for intermediate risk stage IB cervical cancer.

Methods: From January 1993 to December 2007, a total of 100 patients of stage IB were enrolled in this study who had at least two of the following three intermediate risk factors (deep stromal invasion, lymphovascular space involvement, and large tumor size) after radical hysterectomy and all patients had no high risk factors and no radiotherapy. Of these patients, 22 patients had surgery only and 78 patients had cisplatin-based combination chemotherapy as adjuvant therapy postoperatively to improve survival.

Studies on the characteristics and durability of a vertical type organic transistor using indenofluorenedione derivatives as an N-type active material.

We have fabricated a vertical type organic field effect transistor (OFET) using indenofluorenedione derivatives (IF-dione-F) as an n-type organic active material and dimethyldicyanoquinonediimine (DMDCNQI) as an n-type buffer layer. The configuration of the vertical type OFET was ITO (drain)/ IF-dione-F/Metal (gate)/IF-dione-F/DMDCNQI/Metal (source). The characteristics of the vertical type OFET were investigated from the measurements of current-voltage characteristics, contact resistance and device durability.

Extended aortic arch replacement through the L-incision approach.

There are various methods for approaching the aortic arch, such as median sternotomy or lateral thoracotomy. However, accessing the site of distal anastomosis is problematic when the distal arch is extensively involved. We report a case of extended aortic arch replacement and coronary artery bypass through the L-incision approach.

Traumatic tracheobronchial injury: delayed diagnosis and treatment outcome.

Background: Most traumatic tracheobronchial injuries are fatal and result in death. Some milder cases are not life threatening and are often missed at the initial presentation. Tracheobronchial rupture is difficult to diagnose in the evaluation of severe multiple trauma patients.
