#Kazakhstan Rare Saiga Antelopes die of Unknown Disease Killings of tens of thousands of endangered antelopes in ex-Soviet Kazakhstan have happened over the past two weeks.
However, researchers have so far not been able to pin the exact cause behind the disease outbreak.
Scientists said in a report Thursday by the United nations environment programme (UNEP that not even a single animal managed to survive after getting affected by the disease. nseasonal wetness may have been lowered something that their immunity to infection
The test is for detecting current and previous infections with any known human virus, together with HIV and hepatitis C. The method is an efficient substitute to diagnostics available at present.
The method tests for particular viruses individually. Scientists can conduct a single test using Virscan
Stephen Elledge, an HHMI investigator at Brigham and Women's hospital and his colleagues made use of Virscan in order to screen the blood of 569 people in the US, Thailand, South africa and Peru.
Virscan screens the blood for antibodies against any of the 206 species of viruses that are known to attack humans.
According to Ian Lipkin, a professor of epidemiology and director of the Center for Infection and Immunity at Columbia University
3-D imaging at cellular resolution in behaving organisms is a new frontier for biomedical and neuroscience research,
#System Combines Optical Microscopy, MRI Combining optical and MRI techniques, a new imaging system aims to uncover the complexities of tumors to help better tailor cancer treatment.
The preclinical and intravital molecular imaging system houses a window for tissue observation in addition to a larger imaging chamber.
Together they are being used to peer into the microenvironment of tumors and other tissues while learning about the coregistration of multiple lines of imaging data."
"In a study, a tumor cell line was transplanted into a rat and imaged with each of the following:
has been found to be an excellent biomarker for disease. Finally, luminescence, fluorescence and optical imaging are all state-of-the-art imaging techniques that can be used to paint targets as small as a strand of DNA with glowing substances to make them stand out
Results of the study showed that increased lactate production was detected by hyperpolarized MRI in areas of hypoxia
while other parts of a tumor could be rapidly growing or becoming more aggressive. These details tell researchers about the heterogeneity of tumors,
which is essential for developing appropriate research and drug protocols that can navigate all the inherent complexity of not just the anatomy

OCT Could Aid Brain tumor Removal Study: OCT Could Aid Brain tumor Removalbaltimore, June 19, 2015 Optical coherence tomography (OCT) holds promise for guiding surgeons as they operate on brain tumors
and help them avoid removing healthy tissue. After identifying brain cancer's OCT signature, researchers at Johns hopkins university have developed a computer algorithm that rapidly generates a color-coded map that shows cancer in red and healthy tissue in green."
"We envision that the OCT would be aimed at the area being operated on, and the surgeon could look at a screen to get a continuously updated picture of where the cancer is
and isn't,"said professor Xingdi Li. So far the system has been tested on fresh human brain tissue removed during surgeries
and in surgeries to remove brain tumors from mice. The researchers hope to begin clinical trials in patients this summer.
Neurosurgeons walk a tightrope as they try to take out as much of the cancer as possible
while keeping crucial brain tissue intact. Visually distinguishing the two is often impossible.""As a neurosurgeon,
I'm in agony when I'm taking out a tumor, "said Dr. Alfredo Quinones-Hinojosa, a professor of neurosurgery, neuroscience and oncology at the Johns hopkins university School of medicine and the clinical leader of the research team."
"If I take out too little, the cancer could come back; too much, and the patient can be disabled permanently.
We think optical coherence tomography has strong potential for helping surgeons know exactly where to cut."
"Optical coherence tomography that could help surgeons differentiate a human brain tumor, red, from surrounding noncancerous tissue, green.

OCT operates on the same echolocation principle used by bats and ultrasound scanners, but it uses light rather than sound waves,
yielding a higher-resolution image than does ultrasound. And unlike x-rays and CT or PET scans, OCT uses nonionizing radiation to produce images.
Cancers tend to be relatively dense, which affects how they scatter and reflect light. Brain cancer cells also lack the myelin sheaths that coat healthy brain cells,
a factor that has even greater effect on OCT readings than cell density, the researchers said.
it will be a big step up from imaging technologies now available during surgeries, Quinones-Hinojosa said."
The system could be adapted to detect cancers in other parts of the body, said doctoral student Carmen Kut.
She is working on combining OCT with a different imaging technique that would detect blood vessels to help surgeons avoid cutting them.

And the surgery to implant the sensors was minimal. According to Thorvaldur Ingvarsson, an orthopedic surgeon and head of R&d at Ossur, the procedure took 15 minutes,

researchers expose antibodies in the patient blood to molecules with the virusmolecular signature. In the past, researchers could only check a sample for reactions of one type of antibody at a time.
But thanks to Next Generation genetic sequencing, researchers can use Virscan to look for hundreds of antibody reactions at once.
The researchers tested Virscan on samples from almost 600 individuals from the United states Thailand, Peru, and South africa.
After observing over 100 million antibody reactions, the researchers determined that most people had been exposed to about 10 viruses on average,
though a few had antibodies for 84 different viruses. Interestingly, the researchers also uncovered that the immune system sometimes deploys the same antibodies for different viruses that may look similar

a number low enough to qualify for THE WHO to validate that mother-to-child transmission of the disease has been eliminated effectively.
Stopping the transmission of HIV is ne of the greatest public health achievements possible says Margaret Chan,
the director general of THE WHO. That because a reduction in HIV infection in babies could mean that there are fewer adults to transmit the disease to one another,
so the only way to cut down on incidences of the disease is to decrease the number of mosquitoes that carry it.

dengue has been on the rise in Brazil, with an estimated 16 million new cases every year.
Many of the mosquitoes that carry the disease are also resistant to pesticides, which meant that Brazilians were left with few options to decrease dengue prevalence.
The neighborhood in which the researchers tested the modified mosquitoes was a low-income area with high rates of dengue infection
according to local public health officials. Over a one-year period, the researchers released the modified males into the local environment
and monitored the resulting eggs, looking for a characteristic fluorescent marker engineered into the malesgenome.
In the course of that year, the number of disease-carrying mosquitoes decreased by 95 percent as compared to a control group in a neighborhood next door.

#Handheld Device For Surgeons Could Turn off Pain A new handheld tool called the Chimaera will help surgeons find the right nerve with ease by giving them real-time feedback during operations.
This kind of device, its developers claim, will usher in a new age of surgical devices, making delicate nerve procedures easier for surgeons everywhere.
In recent years surgeons have been able to implant devices called neuromodulators that can stop pain
But surgeons have a hard time accessing nerves that are behind the eyes or the face because it's difficult to identify the right one among the jumble,
The Chimaera device helps surgeons identify and access specific nerves. When a surgeon holds the wireless wand-like device near a place where he plans to make an incision,
the Chimaera sends data about that spot to a computer where it is combined with information from a CT SCAN of the patient brain taken previously.
This information is compiled into a single X-ray-like image that the surgeon can see in real time with Google glass
and nerves that surround the place of the incision so that the surgical tool is as precise as possible.
the Chimaera can help the surgeon damage as little as possible on its way to the desired nerve,
where the surgeon can implant the neuromodulator device. Right now these most delicate procedures can only be conducted by a handful of surgeons worldwide, Reuters reports.
But the Chimaera could make neuromodulators so much easier to implant that they could become more commonplace.
what will likely be many devices that give surgeons more feedback during a procedure, which will make surgery easier and more precise o

antibodies will be able to bind to the virus and kill it before it can infect you.
But this new antibody, called CT149, works differently. Normally, antibodies can only stop one virus strain from replicating by preventing it from infecting a normal cell.
But CT149 binds to a different area of the cell membrane called the hemagglutinin stem region.
unlike typical antibodies, can stop more than just one strain of flu virus. The researchers gave the CT149 antibody to mice
the swine flu that reached pandemic infection levels in humans in 2009. This work suggests that future flu vaccines could include this new kind of antibody that would be able to fight the most powerful types of influenza viruses
and stave off several strains at once. That might make for stronger flu vaccines --and possibly reduce the shot's frequency to once every few years e

#New Ebola Vaccine Shows 100 Percent Effectiveness In Early Tests At this time last summer, the horrific and often fatal disease Ebola was ravaging West Africa in the deadliest outbreak
such as the United states. While the worst spread of the disease has been contained, the threat of a future Ebola outbreak persists.
But in an extremely promising medical advance, scientists are now saying that an experimental Ebola vaccine with 100 percent effectiveness has been developed.
A paper published today in The british medical journal Lancet reports that the vaccine which has been tested in Guinea
since March 2015, has shown extraordinary results so far, with 4, 123 people voluntarily vaccinated and all safe from the disease.
The joint studyonducted by international teams from the World health organization, the Guinean Health Ministry, Doctors Without Borders, the Norwegian Institute of Public health and the nonprofit Epicentre research center, among many othersas been 100 percent
effective in vaccinated individuals. his is an extremely promising development, said Dr. Margaret Chan, the Director General of the World health organization (WHO),
The medical authorities carrying out the trial have been using what known as a ing vaccination strategyto test the vaccine efficacy.
This involves inoculating all known contacts of an infected individual, thereby creating a ingof inoculation around the disease and stunting its spread.
This technique was used to tremendous success in the eradication of smallpox. John-Arne Røttingen, Director of the Division of Infectious disease Control at the Norwegian Institute of Public health, also noted in THE WHO's statement that it was this strategy in particular that has allowed for them to follow the dispersed epidemic in Guinea
which has dwindled significantly (THE WHO reported seven cases in the affected region of West Africa last weekhe lowest number of new patients in over a year)
and to continue testing. Furthermore, while VSV-EBOV has shown 100 percent efficacy in individuals, more conclusive evidence is necessary to prove the vaccine ability to protect larger populations from the disease, according to THE WHO. This trait,
known as erd immunity, is especially vital in order for the vaccine to be truly successful. The trial faced some obstacles in the beginning,
particularly for using no placebos, and for carrying out testing and research in the midst of an emergency.
because volunteers knew they were receiving the actual vaccine. This raised a number of questions on ethical and scientific grounds,
but were dismissed ultimately by the medical teams involved for practical reasons. Jeremy Farrar, director of Wellcome Trust, a major supporter of the research, commented on this in an interview with the New york times saying the fact that the trial still achieved positive results in spite of various constraints and limitations,
It is expected that this vaccine will likely be used to stop future outbreaks rather than vaccinate whole populations.
The speed and efficiency with which this vaccine was developed and tested in the midst of a global medical emergency is unparalleled.
