AIMS: Type 2 diabetes (T2DM) is a recognized risk factor for intracranial stenosis (ICS) in China where ischemic stroke is a health priority. In Europe little information is available on T2DM prevalence among Chinese minority groups and vascular screening is commonly limited to extracranial vessels. Feasibility of community-based T2DM screening, differences in T2DM prevalence between Chinese migrants and Italians, and prevalence of ICS among Chinese patients with newly diagnosed T2DM were investigated...

Urinary tract infections (UTI) are the most common infectious diseases in children. Urosepsis in childhood, though rare, is the most complicated possible variant. In newborns and infants, unspecific symptoms are a significant barrier to a fast and reliable diagnosis, which is crucial to successful treatment. In addition to urine and laboratory tests as well as non-invasive examinations (ultrasound), there may be an indication for invasive examinations of the kidneys (DMSA scans) in cases of a severe infection...

In this study, a kind of bismuth vanadium (Bi25VO40) microcube with step surface was successfully synthesized by a fast and mild hydrothermal method. The reaction time and hydrothermal temperature are the key factors which are accounted for the formation of this unique structure. The as-prepared Bi25VO40 microcube exhibited considerably higher visible light photocatalytic activity compared with the smooth one, revealing that fabrication of Bi25VO40 with step surface was an effective method to improve the photocatalytic activity...

Volume reconstruction method plays an important role in improving reconstructed volumetric image quality for freehand three-dimensional (3D) ultrasound imaging. By utilizing the capability of programmable graphics processing unit (GPU), we can achieve a real-time incremental volume reconstruction at a speed of 25-50 frames per second (fps). After incremental reconstruction and visualization, hole-filling is performed on GPU to fill remaining empty voxels. However, traditional pixel nearest neighbor-based hole-filling fails to reconstruct volume with high image quality...

Conventional Doppler ultrasound is useful for visualizing fast blood flow in large resolvable vessels. However, frame rate and tissue clutter caused by movement of the patient or sonographer make visualizing slow flow with ultrasound difficult. Patient and sonographer motion causes spectral broadening of the clutter signal, which limits ultrasound's sensitivity to velocities greater than 5-10mm/s for typical clinical imaging frequencies. To address this, we propose a clutter filtering technique that may increase the sensitivity of Doppler measurements to at least as low as 0...

Penetrating thoracic injuries are rare in Germany and common in urban regions. 10 percent of the patients in Emergency Departments suffer from blunt thoracic trauma. Mechanism of trauma can predict the severity of the injuries. Very fast life-threatening injuries with hemodynamic problems like tension pneumothorax or cardiac tamponade have to be diagnosed. Prehospital emergency physicians need skills in ultrasound for diagnosis and in invasive therapy like chest tube or pericardium drainage tube. The application of an algorithm in exploration of a thoracic trauma seems to be useful...

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is commonly used for the pathological diagnosis in patients with mediastinal lymphadenopathy. Even though the accuracy of EBUS-TBNA is considered high, several authors have tried to outline characteristic ultrasound criteria for malignant mediastinal lymph-node identification to maximize this accuracy. Recently, a color-Doppler patterns classification has been proposed by Nakajima to target suspected mediastinal lymph-nodes...
