Intravascular Ultrasound (IVUS) is an intra-operative imaging modality that facilitates observing and appraising the vessel wall structure of the human coronary arteries. Segmentation of arterial wall boundaries from the IVUS images is not only crucial for quantitative analysis of the vessel walls and plaque characteristics, but is also necessary for generating 3D reconstructed models of the artery. The aim of this study is twofold. Firstly, we investigate the feasibility of using a recently proposed region detector, namely Extremal Region of Extremum Level (EREL) to delineate the luminal and media-adventitia borders in IVUS frames acquired by 20 MHz probes...

Physiological mechanisms of irreversible hydraulic dysfunction in seedlings infected with pine wilt disease (PWD) are still unclear. We employed cryo-scanning electron microscopy (cryo-SEM) to investigate the temporal and spatial changes in water distribution within the xylem of the main stem of 2-year-old Japanese black pine seedlings infested by pine wood nematodes (PWNs). Our experiment was specifically designed to compare the water relations among seedlings subjected to the following water treatment and PWN combinations: (i) well-watered versus prolonged drought (no PWNs); and (ii) well-watered with PWNs versus water-stressed with PWNs (four treatments in total)...

BACKGROUND: Autologous fat grafting (AFG) is an important tool for plastic surgeons treating the aging face. Malar augmentation with fat is often targeted to restore the youthful facial contour and provides support to the lower eyelid. The existence of distinct facial fat compartments suggests a step-wise approach may be appropriate in this regard [1]. Here we describe a three-step approach to malar augmentation using targeted deep malar fat compartmental augmentation, termed the "Boomerang Lift"...

There are many aspects-political, economic, legal, medical, cultural, religious-of the present refugee crisis in Europe. Difficulties at border crossings, settlement programs, life-saving issues, and security measures come to mind immediately, but the refugee crisis also needs to be examined from a psychological angle. This paper outlines psychoanalytic findings on voluntary and forced immigration and human responses to the Other. Change in the twenty-first century is occurring at an unprecedented pace and scale...

Since its emergence near the German-Dutch border in 2011, Schmallenberg virus (SBV) has been identified in many European countries. In this study, we determined the complete coding sequence of seven Hungarian SBV genomes to expand our knowledge about the genetic diversity of circulating field strains. The samples originated from the first case, an aborted cattle fetus without malformation collected in 2012, and from the blood samples of six adult cattle in 2014. The Hungarian SBV sequences shared ≥99.3% nucleotide (nt) and ≥97...

This paper explores intra-regional South-South cross-border patient travel within the context of Southern Africa. South Africa, in particular, has been widely touted as one of the emerging destinations of high-end patients from the Global North alongside other destinations such as Brazil, India, Costa Rica and Thailand. Using South Africa as a case study, the paper demonstrates that South-South cross-border patient travel is far more significant than North-South patient travel both in numerical and financial terms...

Acral melanoma (AM) is a rare subtype of cutaneous malignant melanoma found on acral skin, primarily on the soles of the feet. Although rare, it is the most common subtype of melanoma found in patients of African or Asian ethnicity and has a poor prognosis, often because of the more advanced stage of presentation at diagnosis. In the second of this two-part series, we review the clinical presentation, histopathology, diagnosis and management of AM. Clinically, AM presents as a variegated lesion with blue-black pigment and irregular borders on acral skin...

An upward displacement of the odontoid process into the foramen magnum was observed in the skeletal remains of a young male unearthed from a 14th-17th century cemetery in the north-eastern Italy. Examination of skull bone vestiges and CT-SCAN analysis of the axis exhibited a clear-cut contact zone between the odontoid process and the anterior border of the foramen magnum. In addition, the odontoid process appeared backward deviated. Findings suggest a possible diagnosis of basilar impression/invagination. This anomalous contact may cause compression of neural and vascular structures with a multifaceted series of clinical symptoms...

#17
Horacio F Mayer, Hugo D Loustau
There have been several methods described for the correction of prominent ears, including techniques that excise, bend, suture, score, or cut the auricular cartilage. The Island Technique, proposed by Pitanguy, is based on the creation of a cartilage island to define the antihelix and correct the conchoscaphal angle. Visibility of sharp edges has been the main criticism of this technique. To avoid them, we advise performing an internal bevel incision to round off the edges and achieve a more natural look. Also, sometimes prominent ears are asymmetric with different conchoscaphal angles, determining a residual but protruding upper pole, thus requiring different treatment on each side...
