Miguel Leal-Rato
As a medical student, I have now almost 6 years of academic studies and clinical interaction with numerous patients, though sometimes brief and superficial. I have found that sometimes it is truly hard to grasp how humane a person is behind their sickness. Fortunately, I have been hitherto able to avoid the almost natural desensitization our degree imposes upon us, either through my own process of thought or through a kind warning of some of "my" patients. Having been particularly thrown aback by the keen eye of a patient I had the opportunity to meet in an Oncology ward, I realized that I had much more to consider when studying a clinical case and that rarely a cancer (or a disease whatever it may be) is but a cancer...

Growing evidence suggests some individuals may exhibit dependence to ultraviolet light, a known carcinogen; however, few studies have investigated predictors of tanning dependence (TD).A sub-set of early-onset basal cell carcinoma case-control study participants completed an online survey. The modified-Cut down, Annoyed, Guilty, Eye-opener (mCAGE) and a questionnaire based on the addiction criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (mDSM-IV-TR) were used to classify participants having'Symptoms of TD' if they met criteria for TD on both questionnaires, 'Tendency for TD' if met criteria on only one questionnaire, or 'Not TD'...

LGR4, also known as GPR48, is a member of the leucine-rich, G protein-coupled receptor family. It is widely expressed in tissues of the reproductive system, urinary system, sensory organs, digestive system, and central nervous system. LGR4 plays an important role in the development of various organs and cancer development and progression by modulating multiple signaling pathways. Recent studies have revealed that LGR4 is related with many kinds of human diseases such as gastrointestinal carcinomas. Eye development is a dynamic process regulated by a number of growth factors and cytokines...

This study was designed to estimate radiation-induced secondary cancer risks from high-dose-rate (HDR) brachytherapy and external radiotherapy for patients with cervical cancer based on measurements of doses absorbed by various organs. Organ doses from HDR brachytherapy and external radiotherapy were measured using glass rod dosimeters. Doses to out-of-field organs were measured at various locations inside an anthropomorphic phantom. Brachytherapy-associated organ doses were measured using a specialized phantom that enabled applicator insertion, with the pelvis portion of the existing anthropomorphic phantom replaced by this new phantom...

Deformable image registration (DIR) and interobserver variation inevitably introduce uncertainty into the treatment planning process. The purpose of the current work was to measure deformable image registration (DIR) errors and interobserver variability for regions of interest (ROIs) in the head and neck and pelvic regions. Measured uncertainties were combined to examine planning margin adequacy for contours propagated for adaptive therapy and to assess the trade-off of DIR and interobserver uncertainty in atlas-based automatic segmentation...

Observational studies have shown that interruptions are a frequent occurrence in diagnostic radiology. The present study used an experimental design in order to quantify the cost of these interruptions during search through volumetric medical images. Participants searched through chest CT scans for nodules that are indicative of lung cancer. In half of the cases, search was interrupted by a series of true or false math equations. The primary cost of these interruptions was an increase in search time with no corresponding increase in accuracy or lung coverage...

Surfactant-stripped, nanoformulated naphthalocyanines (nanonaps) can be formed with Pluronic F127 and low temperature membrane processing, resulting in dispersed frozen micelles with extreme contrast in the near infrared region. Here, we demonstrate that nanonaps can be used for multifunctional cancer theranostics. This includes lymphatic mapping and whole tumor photoacoustic imaging following intradermal or intravenous injection in rodents. Without further modification, pre-formed nanonaps were used for positron emission tomography and passively accumulated in subcutaneous murine tumors...

Cathie M Pfleger
The Hippo Pathway is a master regulatory network that regulates proliferation, cell growth, stemness, differentiation, and cell death. Coordination of these processes by the Hippo Pathway throughout development and in mature organisms in response to diverse external and internal cues plays a role in morphogenesis, in controlling organ size, and in maintaining organ homeostasis. Given the importance of these processes, the Hippo Pathway also plays an important role in organismal health and has been implicated in a variety of diseases including eye disease, cardiovascular disease, neurodegeneration, and cancer...

Rab escort protein-1 (REP1) is linked to choroideremia (CHM), an X-linked degenerative disorder caused by mutations of the gene encoding REP1 (CHM). REP1 mutant zebrafish showed excessive cell death throughout the body, including the eyes, indicating that REP1 is critical for cell survival, a hallmark of cancer. In the present study, we found that REP1 is overexpressed in human tumor tissues from cervical, lung, and colorectal cancer patients, whereas it is expressed at relatively low levels in the normal tissue counterparts...
