REVIEW
Gádor-Indra Hidalgo, María Pilar Almajano
Red fruits, as rich antioxidant foods, have gained over recent years capital importance for consumers and manufacturers. The industrial extraction of the phenolic molecules from this source has been taking place with the conventional solvent extraction method. New non-conventional extraction methods have been devised as environmentally friendly alternatives to the former method, such as ultrasound, microwave, and pressure assisted extractions. The aim of this review is to compile the results of recent studies using different extraction methodologies, identify the red fruits with higher antioxidant activity, and give a global overview of the research trends regarding this topic...

Diffuse large B cell lymphoma (DLBCL) is the most common histological subtype of Non-Hodgkin's lymphoma. As treatments continues to evolve, so do imaging strategies, and positron emission tomography (PET) has emerged as the most important imaging tool to guide oncologists in the diagnosis, staging, response assessment, relapse/recurrence detection,and therapeutic decision making of DLBCL. Other imaging modalities including magnetic resonance imaging (MRI), computed tomography (CT), ultrasound, and conventional radiography are also used in the evaluation of lymphoma...

BACKGROUND: Increasing demand for non-invasive skin tightening and body contouring procedures has led to several technological in- novations in energy-based devices such as ultrasound, radiofrequency and cryolipolysis. An emerging trend in the eld is to evaluate whether combination therapies for skin laxity/body contouring using energy-based devices can deliver superior clinical results and patient satisfaction. As such, the objective of this prospective, internal-controlled, blind clinical study was to assess the safety and efficacy of cryolipolysis followed by multipolar radiofrequency with pulsed electromagnetic elds (PEMF) and adjustable pulsed suction for the treatment of skin laxity in the flanks...

Combined intravascular ultrasound and intravascular photoacoustic (IVUS/IVPA) imaging is an emerging hybrid modality being explored as a means of improving the characterization of atherosclerotic plaque anatomical and compositional features. While initial demonstrations of the technique have been encouraging, they have been limited by catheter rotation and data acquisition, displaying, and processing rates on the order of several seconds per frame as well as the use of off-line image processing. Herein, we present a complete IVUS/IVPA imaging system and method capable of real-time IVUS/IVPA imaging, with online data acquisition, image processing, and display of both IVUS and IVPA images...

Rachel R Bengtzen, Ryan C Petering
BACKGROUND: Posterior sternoclavicular dislocations can be challenging diagnostically, as traumatic force often happens to the lateral shoulder rather than directly to the sternoclavicular joint. Shoulder radiographs do not illustrate the sternoclavicular joint well, and can miss the diagnosis. This injury, however, has the potential for life-threatening complications due to proximity of mediastinal structures that might also be injured. CASE REPORT: The following case illustrates a delayed diagnosis of posterior sternoclavicular dislocation...

A 68-year-old female with acute coronary syndrome was transferred to our hospital. Emergency coronary angiography showed 90% stenosis with severe calcification in the proximal right coronary artery (RCA). Intravascular ultrasound (IVUS) images were obtained and showed circumferential heavy calcification without any evidence of plaque rupture. Optical frequency domain imaging (OFDI) images were obtained in the RCA lesion 3 days after the initial coronary angiography. A cavity of plaque rupture in the calcified plaque by using OFDI was observed in the lesion, which could not be recognized by IVUS...

The treatment of non-small cell lung cancer is largely dependent on accurate staging in order to determine appropriate therapy. Despite advances in imaging, such as computed tomography and positron emission tomography, invasive mediastinal staging is frequently needed to rule out mediastinal involvement prior to curative-intent stereotactic ablative radiotherapy or surgical resection. Surgical mediastinal staging with mediastinoscopy, or anterior mediastinotomy, were traditionally considered the gold standard for invasive mediastinal staging...
