Avalanche structural rearrangement through cracking-healing in weakly stressed cold dusty plasma liquids.

We experimentally investigate the spatiotemporal dynamical behaviors of the avalanche structural rearrangement through micro-cracking-healing in weakly stressed cold dusty plasma liquids, and the kinetic origins for their different spatial and temporal classifications. The crystalline ordered domains can be cracked or temporarily sustain and transfer the weak stress to remote regions for cracking-healing. It is found that cracking sites form a fractal network with cluster size following power law distribution in the xyt space.

Bone Regeneration Using Dentin Matrix Depends on the Degree of Demineralization and Particle Size.

Objectives: This study aimed to examine the influence of particle size and extent of demineralization of dentin matrix on bone regeneration.

Materials And Methods: Extracted human teeth were pulverized and divided into 3 groups according to particle size; 200, 500, and 1000 μm. Each group was divided into 3 groups depending on the extent of demineralization; undemineralized dentin (UDD), partially demineralized dentin matrix (PDDM), and completely demineralized dentin matrix (CDDM).

A New Fluorescent Sensor Based on Bisindolizine Derivative.

A fluorescent sensor based on 1,2,1',2'- Tetra(methoxycarbonyl)- 3,3'- bis(p-methylbenzoyl)- 7,7'-bisindolizine (MBI) showing excellent selectivity towards Fe(3+) ions was developed. Under optimized experimental conditions, the fluorescence intensity of 1,2,1',2'- Tetramethoxycarbonyl- 3,3'- bis(p-methylbenzoyl)- 7,7'-bisindolizine was quenched linearly by Fe(3+) ions in the range of 2.00 × 10(-2) to 4.

Lung Cancer Biomarkers.

Lung cancer is the most frequently occurring cancer in the world and continually leads in mortality among cancers. The overall 5-year survival rate for lung cancer has risen only 4% (from 12% to 16%) over the past 4 decades, and late diagnosis is a major obstacle in improving lung cancer prognosis. Survival of patients undergoing lung resection is greater than 80%, suggesting that early detection and diagnosis of cancers before they become inoperable and lethal will greatly improve mortality.

Efficacy of mistletoe for chemical pleurodesis in rats without malignancy.

Chemical pleurodesis is an effective treatment modality to reduce recurrence of malignant effusion. Several agents have been used in chemical pleurodesis but, it is not yet clear which is better. Eighteen Sprague-Dawley rats were used and classified into three groups: a group intrapleurally injected normal saline (group A, n=6), 400mg/kg talc (group B, n=6), and 9mg/kg mistletoe extraction (ME) (group C, n=6).

Infantile Hypertrophic Pyloric Stenosis in Postoperative Esophageal Atresia with Tracheoesophageal Fistula.

Development of infantile hypertrophic pyloric stenosis during postoperative period in EA with TEF is rare. Postoperative vomiting or feeding intolerance in EA is more common which is due to esophageal stricture, gastroesophageal reflux and esophageal dysmotility. A typical case of IHPS also presents with non-bilious projectile vomiting at around 3-4 weeks of life.

Suppressing turbulence of self-propelling rods by strongly coupled passive particles.

The strong turbulence suppression, mainly for large-scale modes, of two-dimensional self-propelling rods, by increasing the long-range coupling strength Γ of low-concentration passive particles, is numerically demonstrated. It is found that large-scale collective rod motion in forms of swirls or jets is mainly contributed from well-aligned dense patches, which can push small poorly aligned rod patches and uncoupled passive particles. The more efficient momentum transfer and dissipation through increasing passive particle coupling leads to the formation of a more ordered and slowed down network of passive particles, which competes with coherent dense active rod clusters.

Thrombomodulin promotes corneal epithelial wound healing.

Purpose: To determine the role of thrombomodulin (TM) in corneal epithelial wound healing, and to investigate whether recombinant TM epidermal growth factor-like domain plus serine/threonine-rich domain (rTMD23) has therapeutic potential in corneal epithelial wound healing.

Methods: TM localization and expression in the murine cornea were examined by immunofluorescence staining. TM expression after injury was also studied.

Coronary stenting with cardiogenic shock due to acute ascending aortic dissection.

A 65-year-old man developed chest pain under cardiogenic shock. Coronary angiography revealed severe stenosis from the ostium of the left main coronary artery (LMCA) to the left anterior descending artery (LAD). Intravascular ultrasound (IVUS) identified a large hematoma that originated from the aorta and extended into the LAD, thereby compressing the true lumen.

Molecular Docking Study for Inhibitors of Aggregatibacter actinomycetamcomitans Toxins in Treatment of Aggressive Perioodontitis.

Introduction: Periodontitis is a chronic inflammatory disease of the periodontal tissues causing periodontal attachment loss and destruction of the alveolar bone which leads to mobility and loss of teeth. Aggregatibacter actinomycetemcomitans (Aa) is a gram negative, capnophilic, coccobacillus that plays an important role in aggressive Periodontitis. Aa produces a variety of virulence factors that facilitate the colonization, invasion and destruction of the periodontal tissues.

Among the numerous diseases that can attack pome fruit trees, apple proliferation and pear decline, both caused by a phytoplasma ('Candidatus Phytoplasma mali' (AP) and 'Ca. P. pyri' (PD), respectively), may result into important losses of quality and quantity of the crop.

Kinetic origin of grain boundary migration, grain coalescence, and defect reduction in the crystallization of quenched two-dimensional Yukawa liquids.

The kinetic origin of grain boundary migration, grain coalescence, and defect reduction in the crystallization of quenched two-dimensional Yukawa liquids are numerically investigated. It is found that, in grain coalescence, stick-slip cracking the region in front of the grain boundary into smaller subgrains corotating with small angle, followed by healing, is the key for aligning lattice misorientation and inducing grain boundary stick-slip advance. Cracking is initiated from the weakly interlocked dislocation along its Burgers vector, which in turn causes dislocation motion along the crack.

Feasibility study of immediate pharyngeal cooling initiation in cardiac arrest patients after arrival at the emergency room.

Aim: Cooling the pharynx and upper oesophagus would be more advantageous for rapid induction of therapeutic hypothermia since the carotid arteries run in their vicinity. The aim of this study was to determine the effects of pharyngeal cooling on brain temperature and the safety and feasibility for patients under resuscitation.

Methods: Witnessed non-traumatic cardiac arrest patients (n=108) were randomized to receive standard care with (n=53) or without pharyngeal cooling (n=55).

Histopathological features of the gastroesophageal junction: an Eastern view.

The definition and features of the gastroesophageal junction (GEJ) and the histopathologic features of the cardiac mucosa remain controversial. Most reports originate from western countries, which have different prevalence of GEJ adenocarcinoma and gastroesophageal reflux disease (GERD) compared to eastern countries. Therefore, we investigated GEJ anatomic and histopathologic features by histological mapping in 30 esophagogastrectomy specimens of middle and lower esophageal squamous cell carcinoma.
