Epidermal Display Screens for On-Body Flexible Medical Devices
Researchers from Nanjing University in China have developed a way to place displays on human skin that are flexible, safe, and don’t require a lot of power to run. The technology will certainly have implications for the field of wearable devices by allowing already existing flexible medical devices to display relevant biomedical information. Schematic showing the structure of a stretchable alternating current electroluminescent (ACEL) device with an electroluminescent (EL) layer between stretchable...

Microscopic Donuts Swim On Their Own to Deliver Therapies Inside Body
While there has been a great deal of work on a variety of micro- and nanoparticles that can deliver drugs and other therapies within the body, compared with bacteria they’re extremely rudimentary in how they can move within the body. Most are simply carried along by the blood to whatever destinations they end up being most attracted to. Bacteria, on the other hand, can propel themselves with consistent determination toward whatever target they desire. Researchers at the Pennsylvania State...

Effect of Bitter Compounds on the Expression of Bitter Taste Receptor T2R7 Downstream Signaling Effectors in cT2R7/pDisplay-Gα16/gust44/pcDNA3.1 (+) Cells
Bitterness is an important taste sensation for chickens, which provides useful sensory information for acquisition and selection of diet, and warns them against ingestion of potentially harmful and noxious substances in nature. Bitter taste receptors (T2Rs) mediate the recognition of bitter compounds belonging to a family of proteins known as G-protein coupled receptors. The aim of this study was to identify and evaluate the expression of T2R7 in chicken tongue tissue and construct cT2R7-1 and cT2R7-2-expressing...

The Pretherapeutic Neutrophil-to-Lymphocyte Ratio for Docetaxel-Based Chemotherapy Is Useful for Predicting the Prognosis of Japanese Patients with Castration-Resistant Prostate Cancer
Introduction and Objectives. The neutrophil-to-lymphocyte ratio (NLR) has been suggested as a simple marker of the systemic inflammatory response in critical care patients. The NLR can be easily calculated from routine complete blood counts in the peripheral blood. This parameter has been reported to be an independent prognosticator for some solid malignancies. In the present study, we examined the importance of the NLR as a prognostic marker for castration-resistant prostate cancer (CRPC) patients...

Angioedema Activity Score (AAS): A Valid and Reliable Tool to Use in Asian Patients
The Angioedema Activity Score (AAS) is recommended by the EAACI/GA2LEN/EDF/WAO guidelines for urticaria as the standard measure for assessing disease activity in patients with recurrent angioedema (RAE). To date, it has been translated into 80 languages for use in 52 countries, but it has not been formally validated in Asian patient populations. As RAE may be different in Asian and non-Asian patients, it is important to validate and characterize the reliability of tools to assess RAE disease activity...

New information on the early Permian lanthanosuchoid Feeserpeton oklahomensis based on computed tomography
The cave deposits of the Lower Permian Richards Spur locality in Oklahoma, USA, have produced an incredible number of terrestrial tetrapod taxa, many of which are currently only known from this locality. One of the many recent taxa to be described from the locality was the small lanthanosuchoid parareptile Feeserpeton oklahomensis. Represented by a well-preserved, near complete skull, F. oklahomensis would have been a small predatory reptile, likely preying upon arthropods, and contributes to the...

Overexpression of MdIAA9 confers high tolerance to osmotic stress in transgenic tobacco
Auxin is a plant hormone that takes part in a series of developmental and physiological processes. There are three major gene families that play a role in the early response of auxin and auxin/indole-3-acetic acid (Aux/IAA) is one of these. Although the genomic organization and function of Aux/IAA genes have been recognized in reference plants there have only been a few focused studies conducted with non-model crop plants, especially in the woody perennial species. We conducted a genomic census and...
