This manuscript describes how to classify nematodes using temporal far-field diffraction signatures. A single C. elegans is suspended in a water column inside an optical cuvette. A 632 nm continuous wave HeNe laser is directed through the cuvette using front surface mirrors. A significant distance of at least 20-30 cm traveled after the light passes through the cuvette ensures a useful far-field (Fraunhofer) diffraction pattern. The diffraction pattern changes in real time as the nematode swims within the laser beam...

BACKGROUND: The Trauma Quality Improvement Project (TQIP) uses an injury prediction model for performance benchmarking. We hypothesize that at a Level I high-volume penetrating trauma center, performance outcomes will be biased due to inclusion of patients with nonsurvivable injuries. METHODS: Retrospective chart review was conducted for all patients included in the institutional TQIP analysis from 2013 to 2014 with length of stay (LOS) less than 1 day to determine survivability of the injuries...

Over the past 15 years, zebrafish have emerged as a powerful tool for studying human cancers. Transgenic techniques have been employed to model different types of tumors, including leukemia, melanoma, glioblastoma and endocrine tumors. These models present histopathological and molecular conservation with their human cancer counterparts and have been fundamental for understanding mechanisms of tumor initiation and progression. Moreover, xenotransplantation of human cancer cells in embryos or adult zebrafish offers the advantage of studying the behavior of human cancer cells in a live organism...

According to the Alzheimer Society of Canada, within the next generation, Canada will experience a more than doubling of individuals living with dementia and a potentially economically crippling 10-fold increase in costs to Canadians. Up to 50% of cases with dementia can be attributed to seven modifiable, predominantly vascular and/or lifestyle-associated, risk factors. Multi-modal dementia risk reduction strategies, targeting diet, exercise, mental stimulation, and vascular risk monitoring, are likely to be the most successful...

Aging is the gradual functional recession of the living tissues or organs caused by a variety of genetic and environmental factors together. Autophagy is a process of degrading cytoplasmic components mediated by lysosomes in eukaryotic cells. Kidney is a typical target organ of aging. Autophagy regulates renal aging. Decrease in autophagy can accelerate renal aging,whereas,increase in autophagy can delay renal aging. During the process of regulating renal aging,the mammalian target of rapamycin (mTOR) and its related signaling pathways including the adenosine monophosphate activated protein kinase (AMPK)/mTOR,the phosphatidylinositol 3-kinase (PI3K)/ serine-threonine kinase(Akt)/mTOR,the AMPK/silent information regulation 1 (Sirt1) and transforming growth factor β (TGF-β) play the important roles in renal aging...

Wound healing on skin involves cell migration and proliferation in response to endogenous electric current. External electrical stimulation by electrical equipment is used to promote these biological processes for the treatment of chronic wounds and ulcers. Miniaturization of the electrical stimulation device for wound healing on skin will make this technology more widely available. Using flexible enzymatic electrodes and stretchable hydrogel, a stretchable bioelectric plaster is fabricated with a built-in enzymatic biofuel cell (EBFC) that fits to skin and generates ionic current along the surface of the skin by enzymatic electrochemical reactions for more than 12 h...

This commentary seeks to examine the role, value and importance of peer-based programmatic approaches for ensuring the effective roll-out of the new hepatitis C (HCV) treatments among those most affected - that is, people who inject drugs (PWID). The authors examine recent approaches to HCV treatment in Australia including the provision of universal access to the new DAA regimens regardless of acquisition, genotype or severity of disease. These approaches are contextualised within wider global strategies to support HCV elimination as a public health threat by 2030 (WHO, 2016)...

There is now an unprecedented opportunity to improve the care of the over 5 million people who are living with Alzheimer's disease and related dementias and many more with cognitive impairment due to brain injury, systemic diseases, and other causes. The introduction of a new Medicare care planning benefit-long sought openly by advocacy organizations and clinicians and badly needed by patients and families-could greatly improve health care quality, but only if widely and fully implemented. We describe the components of this new benefit and its promise of better clinical care, as well as its potential to create a new platform for clinical and health outcomes research...

Photochemistry during the polar Spring leads to atmospheric mercury depletion events (AMDEs): Hg(0), which typically lives for months in the atmosphere, can experience losses of more than 90% in less than a day. These dramatic losses are known to be initiated largely by Br + Hg + M → BrHg• + M, but the fate of BrHg• is a matter of guesswork. It is believed that BrHg• largely reacts with halogen oxides, XO (X = Cl, Br, and I) to form BrHgOX compounds, but these species have never been studied experimentally...

Despite its explosive applications in genome engineering, CRISPR (Clustered Regularly Interspersed Short Palindromic Repeats) has been developed into a versatile tool beyond its well-known nuclease function. In this prospect article, we summarize a few exciting "off-label" applications of CRISPR including manipulating DNA sequences, visualizing chromosomal loci in living cells, and modulating transcription and chromatin structures. These novel applications will likely elevate CRISPR tools into yet another level of sophistication and diversity, leading to many more exciting cell biological discoveries...

Compounds obtained from natural resources have been the important candidates for the discovery and development of drugs. Over the past few decades, marine resources gradually attracted the attention of the majority of researchers, and a number of compounds with various structures or activities have been obtained from sponge, alga, fungus, mollusks and some others. Because of the living conditions in the ocean are higher pressures, more variable temperatures, lower oxygen and lower light than that in the terrestrial environment, marine resources have a lot of organisms that are not available or rare on land...
