3D Stretchable Electronics with Stretchable Interlayer Connectors.

The unique mechanical characteristics of stretchable electronics has significantly expanded applications by overcoming the limitations (rigid, planar) of conventional electronics. However, most reported stretchable electronics are two dimensionally stretchable (laterally stretchable in the -axis) in a single layer or even in multiple layers. In this report, we present three dimensionally (3D) stretchable electronics (laterally and vertically stretchable in the -axes) in multilayered 3D electronic circuits.

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.

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 Retrievability of Calcium Silicate-Based Sealer during Retreatment and the Effectiveness of Additional Passive Ultrasonic Irrigation: A Microcomputed Tomographic Study.

This study investigated the retreatability of EndoSeal MTA (Maruch, Wonju, Korea) according to the presence or absence of a canal isthmus and the additional use of passive ultrasonic irrigation (PUI) through microcomputed tomography (micro-CT) imaging. An epoxy resin sealer (AH Plus (Dentsply DeTrey, Konstanz, Germany)) was used as a reference for comparison. Forty-five artificial mandibular molars (TRUETOOTH #19, DELABS, Santa Barbara, CA) with a mesial canal with an isthmus and a distal canal without an isthmus were obturated using gutta-percha and one of the following sealers ( = 15 each): AH Plus, EndoSeal MTA, and EndoSeal MTA + PUI.

Non-diabetic glycosuria as a diagnostic clue for acute tubulointerstitial nephritis in patients with azotemia.

Background: Glycosuria is one of the manifestations of acute tubulointerstitial nephritis (ATIN), but may also be observed in other renal diseases. In this study, we investigated the value of non-diabetic glycosuria as a diagnostic clue for ATIN.

Methods: We retrospectively reviewed the medical records of adult patients who underwent a kidney biopsy as an evaluation for serum creatinine > 1.

Active photonic wireless power transfer into live tissues.

Recent advances in soft materials and mechanics activate development of many new types of electrical medical implants. Electronic implants that provide exceptional functions, however, usually require more electrical power, resulting in shorter period of usages although many approaches have been suggested to harvest electrical power in human bodies by resolving the issues related to power density, biocompatibility, tissue damage, and others. Here, we report an active photonic power transfer approach at the level of a full system to secure sustainable electrical power in human bodies.

Use of non-steroidal anti-inflammatory drugs correlates with the risk of venous thromboembolism in knee osteoarthritis patients: a UK population-based case-control study.

Objective: We aimed to examine whether the current users of specific NSAIDs have an increased risk of venous thromboembolism (VTE) among knee OA patients.

Methods: We conducted a population-based case-control study using The Health Improvement Network, a database of patient records from general practices in the UK. For every VTE case, we identified five controls matched on age, sex and calendar year of study enrolment.

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).

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.

Surgical treatment of thoracic menigocele associated with neurofibromatosis and kyphoscoliosis.

A 46-year-old man presented with a lateral thoracic meningocele associated with cutaneous neurofibromatosis type I and kyphoscoliosis of the thoracic spine upon medical examination. In the majority of such cases, these meningoceles remain asymptomatic, but surgery is indicated when giant or symptomatic cysts are present. The large thoracic meningocele was successfully extirpated through the transthoracic approach in combination with lumbar puncture and cerebrospinal drainage for decompression of the cyst.

Expression of IL-1beta, MMP-9 and TIMP-1 on the pressure side of gingiva under orthodontic loading.

Objectives: To test the hypothesis that orthodontic pressure does not induce gene transcription of IL-1beta, MMP-9, and TIMP-1 in pressure gingival soft tissue.

Materials And Methods: A total of 14 male Wistar rats were used with three rats as no appliance controls and another three as the sham appliance group. On the 7th and the 14th day after orthodontic loading on the maxillary left molar, four rats were sacrificed, respectively.

Disruption of Nfic causes dissociation of odontoblasts by interfering with the formation of intercellular junctions and aberrant odontoblast differentiation.

We reported previously that Nfic-deficient mice exhibit short and abnormal molar roots and severely deformed incisors. The objective of this study is to address the mechanisms responsible for these changes using morphological, IHC, and RT-PCR analysis. Nfic-deficient mice exhibited aberrant odontoblasts and abnormal dentin formation in molar roots and the labial crown analog of incisors.

Simple formulas for the beam lifetime analysis in an electron storage ring.

Derived are simple and accurate formulas estimating the Touschek and beam-gas scattering lifetimes. These formulas are practical rather than theoretical. They use only the measured total beam lifetime tau and its time derivative dtau/dt to estimate the two lifetimes.
