The Cell Adhesion and Proliferation Enhancement Impact of Low-Temperature Atmospheric Pressure Plasma-Polymerized Heptylamine on the Surface of Ti6Al4V Alloy.

To chemically functionalize the Ti6Al4V alloy surface, a custom-made low-temperature atmospheric pressure plasma reactor device was used to polymerize heptylamine on it. The effect of different deposition times, an important process parameter, was also investigated. For each deposition time group, the surface morphology was observed via scanning electron microscopy (SEM).

Impact of angle on photothermal radiometry and modulated luminescence (PTR/LUM) value.

Objective: To evaluate the impact of scanning angles to detect/quantify non-cavitated caries by photothermal-radiometry and modulated-luminescence (PTR/LUM, Canary System) and to evaluate the association of PTR/LUM value with lesion depth (LD), including sound tissue thickness under the lesion (ST).

Methods: Thirty human extracted premolars were selected based on micro-computed tomography [μ-CT: sound (n=12), lesions into outer-half of enamel (n=6), lesions into inner-half of enamel (n=6), lesions into outer one-third of dentine (n=6)]. Each tooth sample was scanned 90° directly contacted to the center of non-cavitated lesion or sound smooth surface, and tilted 10° and 20° in four directions: buccal/lingual/occlusal/cervical.

High-Throughput Sequencing of Oral Microbiota in Carriage Sjögren's Syndrome Patients: A Pilot Cross-Sectional Study.

Background: This study sought to characterize the saliva microbiota of carriage Sjögren's syndrome (SS) patients compared to oral candidiasis and healthy patients by high-throughput sequencing.

Methods: Fifteen patients were included, with five carriage SS patients (decayed, missing, and filled teeth (DMFT) score 22), five oral candidiasis patients (DMFT score 17), and five caries active healthy patients (DMFT score 14). Bacterial 16S rRNA was extracted from rinsed whole saliva.

Predictors of thromboembolic complications after stent-assisted coiling of acutely ruptured intracranial aneurysms: A retrospective multicenter study.

Background: Stent-assisted coiling (SAC) has been reported to safely and effectively treat wide-necked unruptured intracranial aneurysms. However, SAC of acutely ruptured aneurysms is controversial because of perioperative thromboembolic complications. We aimed to investigate the predictors of the thromboembolic complications after SAC of acutely ruptured aneurysms.

Rupture Risk Assessment for Anterior Communicating Artery Aneurysms Using Decision Tree Modeling.

Background: Although anterior communicating artery (ACoA) aneurysms have a higher risk of rupture than aneurysms in other locations, whether to treat unruptured ACoA aneurysms incidentally found is a dilemma because of treatment-related complications. Machine learning models have been widely used in the prediction of clinical medicine. In this study, we aimed to develop an easy-to-use decision tree model to assess the rupture risk of ACoA aneurysms.

Aneurysm morphological prediction of intracranial aneurysm rupture in elderly patients using four-dimensional CT angiography.

Objective: The natural history of unruptured intracranial aneurysms (UIAs) in elderly patients remains poorly understood, and the treatment of UIAs is controversial. The presence of irregular pulsation detected by four-dimensional CT angiography (4D-CTA) is associated with ruptured aneurysms. We aimed to investigate the morphological predictors of irregular pulsation of aneurysms in elderly patients.

Detection and analyzing plane of non-cavitated approximal caries by cross-polarized optical coherence tomography (CP-OCT).

Objective: The objective was to assess the detection ability and the effect of analyzing plane of CP-OCT for non-cavitated approximal caries.

Methods: Thirty human extracted premolars were selected based on micro-computed tomography [μ-CT: μ- CT = 0: sound (n = 12), μ-CT = 1/2: caries into outer-/inner-half of enamel (n = 6 each), μ-CT = 3: caries into outer one-third of dentine (n = 6)]. Teeth were mounted in a custommade device to simulate approximal contact, and scanned from the marginal ridge above the contact area.

Graphene: Insights on Biological, Radiochemical and Ecotoxicological Aspects.

Graphene, including graphene quantum dots, its oxide and unoxidized forms (pure graphene) have several properties, like fluorescence, electrical conductivity, theoretical surface area, low toxicity, and high biocompatibility. In this study, we evaluated genotoxicity ( analysis using the functional density theory-FDT), cytotoxicity (human glioblastoma cell line), pharmacokinetics, impact on microcirculation and cell internalization assay. It was also radiolabeled with lutetium 177 (177Lu), a beta emitter radioisotope to explore its therapeutic use as nanodrug.

PM2.5 concentration modeling and prediction by using temperature-based deep belief network.

Air quality prediction is a global hot issue, and PM is an important factor affecting air quality. Due to complicated causes of formation, PM prediction is a thorny and challenging task. In this paper, a novel deep learning model named temperature-based deep belief networks (TDBN) is proposed to predict the daily concentrations of PM for the next day.

Morphological risk model assessing anterior communicating artery aneurysm rupture: Development and validation.

Objective: Prediction of the rupture risk in anterior communicating artery (ACoA) aneurysms remains challenging. We aimed to investigate the association of detailed morphologies with ACoA aneurysm rupture.

Patient And Methods: 759 consecutive patients with ACoA aneurysms were identified from December 2007 to January 2016.

The safety and efficacy of the LVIS stent for the treatment of ruptured intracranial aneurysms within 24 hours: A multicenter retrospective study.

Objective: Stent-assisted coiling is increasingly used in the treatment of acutely ruptured intracranial aneurysms. However, the optimal timing of the stent-assisted coiling remains unknown. We aimed to investigate the safety and efficacy of the Low Profile Visualized Intraluminal Support (LVIS) stent for ruptured aneurysms treatment within 24 h comparing to the treatment between 25 and 72 h of symptom onset.

Teeth were mounted in a custom-made device to simulate approximal contact.

Endovascular Coiling versus Surgical Clipping of Very Small Ruptured Anterior Communicating Artery Aneurysms.

Background: Endovascular coiling of anterior communicating artery (ACoA) aneurysms has evolved dramatically. Ruptured ACoA aneurysms are more likely to be smaller. We aimed to investigate the safety and efficacy of endovascular coiling of very small ruptured ACoA aneurysms compared with surgical clipping.

Concomitant aneurysm detection in an intracranial dolichoectasia mouse model using a MicroFil polymer perfusion technique.

Objective: To assess the feasibility of using MicroFil polymer perfusion to detect concomitant saccular aneurysms in an intracranial arterial dolichoectasia (IADE) model in mice, and to report detailed histomorphometric features of these aneurysms.

Materials And Methods: IADE models were created in C57/BL6 mice via microsurgical injection of 25 mU elastase into the cisterna magna. The cerebral vasculature was perfused with MicroFil polymer and harvested at 1, 3, and 7 days, and 2 and 4 weeks (n=8 for each group).

Necrotizing gingivostomatitis and osteonecrosis associated with antithyroid drug propylthiouracil therapy.

A 43-year-old Chinese female had been diagnosed with hyperthyroidism 15 years ago. She was recently administered 150 mg/day propylthiouracil (PTU). After 3 weeks of PTU administration, she developed necrotizing stomatitis and osteonecrosis, most likely due to secondary effects from the PTU treatment.

Ultrasonographic features of Langerhans cell histiocytosis of the thyroid.

Langerhans cell histiocytosis (LCH) is a rare disease, especially when it involves the thyroid gland. Awareness of ultrasonic features will be helpful for a clinician who should consider this disease in the differential diagnosis from other more common thyroid disorders, especially prior to surgery. Here, we report two patients who have histologically confirmed LCH of the thyroid and summarize the reported cases with ultrasonographic scans from the last 10 years (n=10).
