Researchers use miniature radio transmitters to track movements of kissing bugs

crnksrcbu
Source:https://www.entsoc.org/ Jul 10 2018With the continuing advance of technology, radio tracking devices keep getting smaller and smaller. And that's bad news for stealthy insects like kissing bugs.In a new pilot study, researchers in Texas successfully attached miniature radio transmitters to kissing bugs and tracked their movements. Kissing bugs, also known as triatomine bugs, are a group of bloodsucking insects, found in Latin America and the southern United States, that transmit the pathogen that causes Chagas disease in humans and animals. They typically move at night and hide during day, and uncovering their secretive movements could play a key role in reducing their impact as a disease vector. The study's findings are published in a new report in the Journal of Medical Entomology."While studying kissing bugs in Texas, we have been…

Source:https://jamanetwork.com/ Aug 13 2018Bottom Line: Lumpectomy plus radiation was associated with a small clinical benefit in reduced risk of breast cancer death compared with lumpectomy or mastectomy alone in women with ductal carcinoma in situ (DCIS), a noninvasive early form of breast cancer.Why The Research Is Interesting: Patients with DCIS are often treated with radiation after lumpectomy, although it has remained unclear whether this can reduce the risk of dying from breast cancer.Related StoriesTrends in colonoscopy rates not aligned with increase in early onset colorectal cancerSugary drinks linked to cancer finds studyHow cell-free DNA can be targeted to prevent spread of tumorsWho and When: More than 140,000 U.S. women who had DCIS between 1998 and 2014; this study compared lumpectomy plus radiation vs. lumpectomy alone, lumpectomy vs. mastectomy, and lumpectomy…

New screening strategy identifies novel inhibitors that may help develop cure for

crnksrcbu
Reviewed by Alina Shrourou, B.Sc. (Editor)Sep 10 2018Parkinson's disease (PD) is the most common movement disorder in the world. PD patients suffer from shaking, rigidity, slowness of movement and have difficulties walking. It is neurodegenerative disease and is caused by the loss of dopaminergic neurons in the brain. Currently PD cannot be cured or even halted in its development, but symptoms may be treated to some degree. Probably the single most important cause of PD is the aggregation of the natively unfolded protein α-synuclein (αSN). αSN can form both small oligomeric complexes (αSOs) as well as large fibrillary deposits; the αSOs are thought to be the most toxic species. If we can prevent or reduce αSN aggregation we have a good way to halt PD development. So far it has…

After last weeks shock scientists scramble to prevent more geneedited babies

crnksrcbu
Bioethicist Alta Charo of the University of Wisconsin Law School in Madison says He seemed “quite sincere” in his aim to engineer babies who would not suffer the illness and stigma that had plagued their HIV-infected father. He appeared to believe he had complied with ethical guidelines for what’s known as germline editing—creating heritable alterations in early embryos, sperm, or eggs. “That kind of rocked me back,” Charo says. “He talked aboutRobert Edwards, the ‘father’ of IVF [in vitro fertilization]. I got the strong impression that he saw Robert Edwards as a kind of hero, a paradigm breaker, a disrupter, and that he wanted to model himself after that.”It seems unlikely history will view He in the same light as Edwards, who won a Nobel Prize, but the Chinese researcher…

This is the first known sea turtle—and it laid hard eggs By Sid PerkinsDec. 19, 2018 , 7:00 AM Unlike all modern sea turtles, which lay eggs with soft, pliable shells, the earliest known sea turtle deposited eggs with hard, mineralized shells on the beach, a new study suggests.The 120-million-year-old fossil (image above) was unearthed in central Colombia more than a decade ago. It belongs to Desmatochelys padillai, a species of sea turtle first described from other fossils in 2015. Since then, computerized tomography scans of the new specimen have revealed more than four dozen almost spherical eggs ranging between about 32 and 43 millimeters in diameter (four shown loose at left, above). And other tests, including a microscopic look at the mineral structure of the well-preserved eggs, reveals eggs…

iPhone Envy May Have Felled Galaxy Note7

Samsung's desire to match the iPhone 7 Plus led it to implement an aggressive design and manufacturing approach that led to problems with its Galaxy Note7 -- including some instances of the smartphones bursting into flames -- and eventually its global recall, Instrumental reported last week.Instrumental engineers tore down a Galaxy Note7, and found "evidence in the design of an intellectual tension between safety and pushing the boundaries," CEO Anna Shedletsky revealed.Samsung engineers "designed out all of the margin in the thickness of the battery," she noted.It "sits within a CNC-machined pocket -- a costly choice likely made to protect it from being poked by other internal components," Shedletsky speculated."For something that is innovative and new, you design the best tests that you can think of, and validate that the…

Translucent wonder material used on stadium roofs helps measure protein particles

crnksrcbu
Reviewed by James Ives, M.Psych. (Editor)Mar 1 2019Understanding how proteins clump together is essential in modern pharmaceuticals. When these tiny particles aggregate, they can alter the effectiveness of both vaccines and drugs, especially many of the new, popular formulations derived from monoclonal antibodies. Despite its importance, the industry has yet to find an effective, large-scale way to measure particle clumping accurately. A new reference material, released today by the National Institute of Standards and Technology (NIST), aims to solve this protein problem with help from a translucent wonder material that's often used on stadium roofs.Biologic drugs are being prescribed today for a wide variety of ailments and diseases, including cancer, psoriasis, colitis and rheumatoid arthritis.

Researchers discover ingredient vital for blood vessel formation

Reviewed by James Ives, M.Psych. (Editor)Mar 14 2019Researchers at the University of Virginia School of Medicine have discovered an ingredient vital for proper blood vessel formation that explains why numerous promising treatments have failed. The discovery offers important direction for efforts to better treat a host of serious conditions ranging from diabetes to heart attacks and strokes. Source:https://newsroom.uvahealth.com/2019/03/12/found-the-missing-ingredient-to-grow-blood-vessels/ Until now, scientists seeking to grow blood vessels have focused almost exclusively on growing only the inner layer of blood vessels, which are made up of endothelial cells. The hope was that these endothelial cells would then recruit any other cell types needed to form a complete, functional blood vessel. But researchers led by Gary K. Owens, PhD, director of UVA's Robert M. Berne Cardiovascular Research Center, have determined that those vessels…

Framingham cardiovascular risk prediction model from the 1990s still gives the best

crnksrcbu
Reviewed by James Ives, M.Psych. (Editor)Mar 19 2019The so-called Framingham cardiovascular risk calculator was developed in 1991 on the basis of data gathered in the USA between 1968 and 1975. It is named after the town of the same name in Massachusetts, where a systematic evaluation of heart health had previously been conducted in the late 1940s. Using figures from the Federation of Austrian Social Insurance Institutions gathered between 2009 and 2014, Daniela Dunkler working with a team from MedUni Vienna's Centre for Medical Statistics, Informatics and Intelligent Systems (Division of Clinical Biometrics) investigated whether this prognostic model is still valid today. The outcome: even in the 21st century, it is still providing the best and most accurate results - especially for Austria or other Central European countries with a…
