Bioinspired materials enable new health-care options, reports Journal of Biomedical Optics
2014-10-03
(Press-News.org) BELLINGHAM, Washington, USA -- New applications of structures and materials that replicate complex yet efficient arrangements that have evolved in nature over millennia are featured in a special section on biomimetic and bioinspired materials for applications in biophotonics in the October issue of the Journal of Biomedical Optics. The journal is published by SPIE, the international society for optics and photonics, in the SPIE Digital Library. Several of the peer-reviewed articles are accessible via open access.

"Biomimetic and bioinspired materials present an emerging field in the areas of biomedicine, bioengineering, and biological sciences," write the special section's guest editors Bahman Anvari (University of California, Riverside), Pablo del Pino (CIC biomaGUNE, Bioengineered Particles Lab), Vikas Kundra (University of Texas M.D. Anderson Cancer Center), and Wolfgang Parak (Philipps Universität Marburg) in their guest editorial.

Of particular interest is the current trend toward the production of biofunctional materials that are able to interact with light, thereby enabling applications in therapy, biosensing, and bioimaging, the editors note. The aim of the special section is to present some of the current state-of-the-art research activities on the use of such materials in relation to the field of biophotonics.

The open access papers include the following topics: "High temperature heat source generation with quasi-continuous wave semiconductor lasers at power levels of 6 W for medical use" by Takahiro Fujimoto (Clinic F, Tokai University, and Keio University), et al. The technique has applications in laser surgery, including for herniated disk repair with extremely shortened patient recovery time. "Analytical strategies based on quantum dots for heavy metal ions detection" by Margarita Vázquez-González (University of Santiago de Compostela and Philipps University of Marburg) and Carolina Carrillo-Carrion (Philipps University of Marburg). The paper comments on sensing strategies using quantum dots to assess heavy metal contamination, a major concern to human health because these substances are toxic and retained by the ecological system. "Specific tumor labeling enhanced by polyethylene glycol linkage of near infrared dyes conjugated to a chimeric anti-carcinoembryonic antigen antibody in a nude mouse model of human pancreatic cancer" by Ali Maawy (University of California, San Diego), et al. Their results demonstrate enhanced selective tumor labeling by dyes conjugated to a tumor-specific antibody, suggesting their future clinical use in fluorescence-guided surgery. "Tailoring the interplay between electromagnetic fields and nanomaterials toward applications in life sciences: a review" by Pablo del Pino (CIC BiomaGUNE, Bioengineered Particles Lab). The paper provides an overview of the most relevant parameters and promising applications of electromagnetic-active nanoparticles for applications in life science, with a view toward tailoring the interaction of nanoparticles with electromagnetic fields.

Other papers concern quantitative evaluation and visualization of size effect on cellular uptake of gold nanoparticles by multiphoton imaging-UV/Vis spectroscopic analysis, and Europium-quantum dot nanobioconjugates as luminescent probes for time-gated biosensing.

WSU undergrad helps develop method for detecting water on Mars

WSU undergrad helps develop method for detecting water on Mars
2014-10-03
PULLMAN, Wash.—A Washington State University undergraduate has helped develop a new method for detecting water on Mars. Her findings appear in Nature Communications, one of the most influential general science journals. Kellie Wall, 21, of Port Orchard, Wash., looked for evidence that water influenced crystal formation in basalt, the dark volcanic rock that covers most of eastern Washington and Oregon. She then compared this with volcanic rock observations made by the rover Curiosity on Mars' Gale Crater. "This is really cool because it could potentially be useful for ...

Batteries included: A solar cell that stores its own power

Batteries included: A solar cell that stores its own power
2014-10-03
COLUMBUS, Ohio—Is it a solar cell? Or a rechargeable battery? Actually, the patent-pending device invented at The Ohio State University is both: the world's first solar battery. In the October 3, 2014 issue of the journal Nature Communications, the researchers report that they've succeeded in combining a battery and a solar cell into one hybrid device. Key to the innovation is a mesh solar panel, which allows air to enter the battery, and a special process for transferring electrons between the solar panel and the battery electrode. Inside the device, light and oxygen ...

Too many stroke patients miss out on the window to regain crucial functions

2014-10-03
Too many stroke patients in Canada are not getting the rehabilitation they need to return to a healthy, active life, according to a new study which will be presented at the Canadian Stroke Congress in Vancouver tomorrow. The research findings strongly suggest that such decisions are being made based on what services are available in the health system rather than what patients really need. It found that overall just 16 per cent of patients with stroke were discharged to inpatient rehabilitation but that the rates varied widely by province (1% to 26%) and hospital (0% to ...

Moderate weekly alcohol intake linked to poorer sperm quality in healthy young men

2014-10-03
They base their findings on 1221 Danish men between the ages of 18 and 28, all of whom underwent a medical examination to assess their fitness for military service, which is compulsory in Denmark, between 2008 and 2012. As part of their assessment, the military recruits were asked how much alcohol they drank in the week before their medical exam (recent drinking); whether this was typical (habitual); and how often they binge drank, defined as more than 5 units in one sitting, and had been drunk in the preceding month. They were also invited to provide a semen sample ...

High alcohol intake linked to heightened HPV infection risk in men

2014-10-03
There is some evidence to suggest that alcohol impairs the workings of the immune system, both in terms of the initial protective inflammatory response to infection and the development of subsequent immunity. And habitual drinking is known to increase susceptibility to bacterial pneumonia, septicaemia, tuberculosis and viral hepatitis. The researchers therefore wanted to find out if there was any association between drinking patterns and susceptibility to HPV infection. They included 1313 men who were already taking part in the US arm of the HPV in Men (HIM) study, ...

Gout linked to heightened diabetes risk

2014-10-03
Previous research has suggested that gout might be associated with diabetes, but the findings were restricted to one study of men at high risk of heart disease and stroke. The researchers wanted to know if the link existed in the general population, and also applied to women. They searched the Health Improvement Network (THIN), an electronic database of the anonymised health records of almost 7.5 million patients registered with 477 general practices across the UK. They included adults who were at least 20 years old, and whose details had been entered into the database ...

The Lancet: Ovarian tissue and egg freezing should be made widely available to prevent

2014-10-03
Ovarian tissue and egg freezing to preserve fertility should no longer be reserved for cancer patients, and healthy women should also be offered these options to safeguard their future chances of conceiving a child, say world renowned fertility experts writing in a new Series on fertility preservation, published in The Lancet [Paper 3]. Over the past 10 years, researchers have restored the fertility of female cancer patients who would otherwise have been left infertile after treatment, having been offered oocyte cryopreservation. The technique enables women to freeze ...

The Lancet: Second case of apparent HIV 'cure' in a baby followed by reappearance of virus

2014-10-03
Researchers today report the case of a baby, born HIV-positive, who appeared to have been cured of HIV after being given early antiretroviral treatment (ART) to combat the virus, but ultimately exhibited detectable HIV infection. The case report, published in The Lancet, is the second report of apparent viral remission followed by rebound in a baby given early ART treatment, after the case of the 'Mississippi baby' received widespread attention in 2013―14. A team of researchers, including Professor Mario Clerici at the University of Milan and the Don Gnocchi Foundation ...

Blood tests predict kidney disease patients' risk of developing heart failure

2014-10-03
Washington, DC (October 2, 2014) — Two blood markers are strongly linked with the development of heart failure in individuals with mild to severe kidney disease, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). Elevations in these markers may indicate subclinical cardiovascular changes that subsequently contribute to the development of heart failure. Patients with chronic kidney disease (CKD) are at increased risk of developing heart failure and other cardiovascular diseases. Nisha Bansal, MD, MAS (University ...
