may change the way doctors approach treatment for patients who develop potentially deadly infections and may also help the food industry screen against contamination with harmful pathogens, according to researchers at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon, South korea.
Described this week in The Optical Society (OSA) journal, Optics Express, the new approach involves bouncing laser light off individual bacteria under the microscope,
which is still the gold standard in the health care industry for making a definitive diagnosis. Also routinely used today is a newer method for rapidly identifying bacteria based on a DNA-analysis technique called quantitative polymerase chain reaction (qpcr),
"This means the present method can be utilized as a prescreening test for point-of-care bacterial diagnosis for various applications including medicine and food hygiene.""
"Why Speed Matters in Infection Control In hospitals and clinics worldwide, bacterial infections are a major source of illness,
In the most severe cases, bacterial poisoning causes severe disease and syndromes like sepsis, meningitis, pneumonia,
and gastroenteritis all of which can be deadly unless the patient is given immediate and appropriate treatment.
The true challenge of fighting those infections is time. In order to best treat their patients, doctors would like to know exactly which bacteria they are infected with,
but the lost hours or days spent identifying the exact pathogen can make the road to recovery that much steeper.
Sepsis, for instance, can develop so rapidly that mortality has been seen to increase by 9 percent per hour until treatment is given.
Waiting two days may kill the patient, Park added. For that reason, many hospital-acquired infections are treated presumptively,
before they are identified definitively, using broad-spectrum antibiotics. These powerful combinations of potent drugs are often effective,
allowing doctors to prescribe the best drugs available to treat an infection and improving outcomes for people with hospital-acquired infections though the effectiveness of the approach remains to be proven in future clinical trials.
In their initial experiments, Park and his colleagues showed as a proof of principle that they could identify bacteria with high accuracy.
The first three are known all pathogens to infect humans through the food chain or via hospital-acquired infections.
which is the base for Anthrax. Under a microscope, all four of these rodlike bacteria look nearly identical.
In addition to helping in the clinic the new method may be useful in the food industry or for homeland security applications.

#Ultracompact Highly sensitive Nanomechanical Sensor Can Detect Viral Disease Markers Two young researchers working at the MIPT Laboratory of Nanooptics and Plasmonics,
such as viral disease markers, which appear when the immune system responds to incurable or hard-to-cure diseases,
including HIV, hepatitis, herpes, and many others. The sensor will enable doctors to identify tumor markers,
whose presence in the body signals the emergence and growth of cancerous tumors. The sensitivity of the new device is characterized best by one key feature:
according to its developers, the sensor can track changes of just a few kilodaltons in the mass of a cantilever in real time.
One Dalton is roughly the mass of a proton or neutron, and several thousand Daltons are the mass of individual proteins and DNA molecules.
So the new optical sensor will allow for diagnosing diseases long before they can be detected by any other method,
#Nanoparticles Arrest Destruction of Beta Cells and Avoid Diabetes Development This work led to more studies with the support of the Spanish Government, Catalan Government and private patrons with a keen interest in it.
Thanks to this, the article published today in PLOS ONE describes a new step towards the creation of a vaccine,
and even curing the disease in humans. Initially the researchers avoided the destruction of the insulin-producing pancreatic cells (beta cells) in the body by modifying the individual's immune cells, known as dendritic cells.
This important step requires the extraction of the subjects'dendritic cells for their subsequent manipulation and re-injection.
and avoid Diabetes development. This technique could be a much better candidate for a human vaccine.
The invention is protected commercially and an international patent has been applied for. Droplets of fat and water which can be produced on a large scaleliposomes have been used in several medical treatments.
They are not cells, but droplets with an external fat membrane, similar to cell membranes. They can be made using a very specialized process,
The Catalan researchers are the first group in the world to use liposomes that imitate naturally dying cells to fight against Diabetes.
Next stepsafter showing that liposomes prevent the onset of Type 1 Diabetes in mice, the next steps are to test it in human cells in vitro,
to start clinical trials on human candidates for preventive vaccination and to cure the disease by combining the vaccine with regenerative therapies.
The Germans Trias Institute plans to carry out these steps with patients at the hospital and to optimize the product by dosage and guideline studies.
It is planned also to optimize the product for personalization. To achieve these objectives more competitive funding will be necessary from public agencies.

Because these electrons can travel only 1 to 2 nanometers human hair is about 60,000 nanometers widehey do not affect healthy tissue and organs nearby.
you get this big flux of low energy electrons coming out. he finding suggests a new avenue for radiation oncology:
then affix the nanoparticles to antibodies targeting malignant tumors and put them in a liquid that cancer patients could take via a single injection.
Theoretically, the nanoparticles would attach to the tumor and emit low energy electrons, destroying the tumor DNA.
The gold-based nanoparticles would be flushed out of the body, Sykes says, unlike free iodine-125,
which can accumulate in the thyroid gland and cause cancer. If proven, this approach could be a potential improvement over current radiation therapy protocols, in
which doctors treat some cancers by putting radioisotopes, including iodine-125, into tiny titanium capsules and implanting them in tumors.
Instead of emitting large amounts of low energy electrons as the gold-bound iodine does, the titanium capsules inhibit radiation,
Sykes says, making such therapies less effective than they could be. He has applied for a patent on the new technique.
Researchers in Sykes'lab are now assessing precisely how the low energy electrons travel through biological fluids.

#Encapsulated, Nanobody-Targeted Drugs Cold Help Treat Sleeping sickness Sleeping sickness, or African trypanosomiasis, is caused by trypanosome parasites transmitted by tsetse flies
The disease is considered fatal if untreated, but as it affects mostly poor people in low-income countries,
A study published on June 25th in PLOS Pathogens reports a new way to circumvent drug resistance
a high-tech approach with potential applications to other infectious diseases. Current treatment of sleeping sickness relies primarily on four drugs.
Three of these drugs get into the interior of the parasite cells via the trypanosome's transport proteins that normally supply the parasite with nutrients,
which is why the chances of developing an effective vaccine have been deemed low.)They show that this new formulation reduces the minimal curative dose in a disease model, based on infections in mice, by 100-fold and,
most importantly, circumvents drug resistance in a cell line that is resistant as a result of mutations in the transporter that mediates drug uptake.
#Nanotechnology Drug in Droplets for Painless Treatment of Secondary Blindness The Mexican company"Medical and Surgical Center for Retina"created a way to transport drugs,
in order to avoid risks and painful treatments in people with secondary blindness due to chronic degenerative blindness such as diabetic retinopathy and degeneration of the eye.
The innovative formula results eliminates the need to administrate the drug by intraocular injection. It is a nanotechnology product,
"With this technology hospitals that have no resources can apply the needed drugs, without requiring a a specialist or a particular facility for the administration.
"The doctor Juan carlos Altamirano Vallejo, medical director of the Medical and Surgical Center for Retina, mentions that the conditions that originate in the retina are caused mostly by chronic degenerative diseases such as diabetes (diabetic retinopathy
Patients with this conditions usually require one injection per month which comes at a very high cost
and Innovation and plans to conclude the Clinical Research regulated by the Federal Commission for Protection Against Health risks (COFEPRIS) next year.
The idea is for the medicine to be distributed in state and private health institutions. So far
the achieved results are the same as the ones obtained with intraocular injection, but without the inherent risks of this procedure, such as infection or retinal detachment.
Current talks are being held with COFEPRIS to conduct a study within several diseases and increase its use for different conditions.
In the United states, patients who have followed the treatment have had positive results. The Medical and Surgical Center for Retina provides medical care

#MEMS Innovations Enable Commercialization of Implantable Microchips for Drug-Delivery An implantable, microchip-based device may soon replace the injections
and pills now needed to treat chronic diseases: Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable,
microchip-based devices that store and release drugs inside the body over many years. Invented by Microchips Biotech cofounders Michael Cima, the David H. Koch Professor of Engineering,
each capped with a metal membrane, that store tiny doses of therapeutics or chemicals. An electric current delivered by the device removes the membrane,
for example, diabetes, cancer, multiple sclerosis, and osteoporosis. Now Microchips Biotech will begin co-developing microchips with Teva Pharmaceutical, the world largest producer of generic drugs,
to treat specific diseases, with licensing potential for other products. Teva paid $35 million up front, with additional milestone payments as the device goes through clinical trials before it hits the shelves. bviously,
this is a huge validation of the technology, Cima says. major pharmaceutical company sees how this technology can further their efforts to help patients.

of life-a cellular recycling unit with a role in many diseases. The proteasome complex is present in all multicellular organisms,
and plays a critical role in cancer by allowing cancer cells to divide rapidly. Researchers used a technique called electron cryo-microscopy,
Scientists from The Institute of Cancer Research, London, and the Medical Research Council (MRC) Laboratory of Molecular biology in Cambridge were able to visualise the proteasome complex down to a resolution of around 3. 5 Angstroms,
and was funded by Cancer Research UK and the MRC. The research could help other scientists to use CRYO EM in structure-based drug design studies-in which researchers build the best possible drugs starting from a molecule which already binds to the active site of a target protein.
Blocking the proteasome prevents this regulated recycling of amino acids and triggers controlled cell death, particularly in fast-dividing cells typical of cancer.
Senior study author Dr Edward Morris, Team Leader in Structural Electron microscopy at The Institute of Cancer Research, London, said:"
"Dr Emma Smith, senior science communications officer at Cancer Research UK, said:""Revealing the molecule's detailed shape could be the first step towards designing more precise drugs to block it.

#Smart Sensor Chip with Nanocavities for Early Prostate Cancer Diagnosis Researchers at the University of Birmingham believe that the novel technology will help improve the process of early stage diagnosis. Glycoprotein molecules,
Because of their essential role in our immune response, they are useful clinical biomarkers for detecting prostate cancer and other diseases.
In doing so, they developed a more accurate and efficient way of diagnosing prostate cancer than the current tests
so could feasibly be kept on the shelf of a doctors'surgery anywhere in the world.
Problematically for diagnosis, the protein part of glycoproteins does not always change if the body is diseased.
The findings, published in the journal Chemical science, show how the rate of false readings that come with antibody based diagnosis can be reduced by the smart technology that focuses on the carbohydrate part of the molecule.
the team wanted to identify the presence of disease by detecting a particular glycoprotein which has specific sugars in a specific location in the molecule.
the sugar part of the prostate cancer glycoprotein is reacted with a custom-designed molecule that contains a boron group at one end (the boron linkage forms a reversible bond to the sugar).
and the only key that will fit is the specific prostate cancer glycoprotein that we're looking for.
"Dr John Fossey added,"It's estimated that one in eight men will suffer from prostate cancer at some point in their life,
so there's a clear need for more accurate diagnosis. By focussing on the sugar, we appear to have hit the'sweet spot'for doing just that.
and collaboration with commercial partners, will open the door to adapting the current technology for other diseases.
Lots of diseases produce specific glycoproteins, so there are a number of possible avenues to improve the accuracy of our diagnoses."
