PET myocardial perfusion imaging more effective than SPECT scans in detecting coronary disease — ScienceDaily

Patients who receive cardiac positron emission testing (PET) imaging instead of single photon emission computed tomography (SPECT) scan experienced a significant increase in the detection of severe obstructive coronary artery disease, according to researchers at the Intermountain Medical Center Heart Institute in Salt Lake City. Both, PET and SPECT scans are nuclear imaging techniques that provide metabolic and functional information of the heart. PET scans provide better image resolution and quality, but have not yet gotten widespread adaptation compared to…

Is your stress changing my brain? Stress isn’t just contagious; it alters the brain on a cellular level — ScienceDaily

In a new study in Nature Neuroscience, Jaideep Bains, PhD, and his team at the Cumming School of Medicine’s Hotchkiss Brain Institute (HBI), at the University of Calgary have discovered that stress transmitted from others can change the brain in the same way as a real stress does. The study, in mice, also shows that the effects of stress on the brain are reversed in female mice following a social interaction. This was not true for male mice. “Brain changes…

Researchers develop optical tools to detect metabolic changes linked to disease

Credit: Irene Georgakoudi, Tufts University Metabolic changes in cells can occur at the earliest stages of disease. In most cases, knowledge of those signals is limited, since we usually detect disease only after it has done significant damage. Now, a team led by engineers at Tufts University School of Engineering has opened a window into the cell…

Calcium may play a role in the development of Parkinson’s disease — ScienceDaily

Researchers have found that excess levels of calcium in brain cells may lead to the formation of toxic clusters that are the hallmark of Parkinson’s disease. The international team, led by the University of Cambridge, found that calcium can mediate the interaction between small membranous structures inside nerve endings, which are important for neuronal signalling in the brain, and alpha-synuclein, the protein associated with Parkinson’s disease. Excess levels of either calcium or alpha-synuclein may be what starts the chain reaction…

The antibiotic cocktail produced by symbiotic bacteria changed very little in the course of evolution and its antipathogenic effect remained unaltered — ScienceDaily

The discovery of penicillin about 90 years ago and the widespread introduction of antibiotics to combat infectious diseases have revolutionized human medicine. However, in recent decades, the increase in multidrug-resistant pathogens has confronted modern medicine with massive problems. Insects have their own antibiotics, which provide natural protection against germs. A team of scientists from the Johannes Gutenberg University in Mainz and the Max Planck Institute for Chemical Ecology in Jena have now found that beewolves, unlike humans, do not face…

Scientists image molecules vital for gene regulation — ScienceDaily

All the trillions of cells in our body share the same genetic information and are derived from a single, fertilized egg. When this initial cell multiplies during fetal development, its daughter cells become more and more specialized. This process, called cell differentiation, gives rise to all the various cell types, such as nerve, muscle, or blood cells, which are diverse in shape and function and make up tissues and organs. How can the same genetic blueprint lead to such diversity?…

Highly stretchable aqueous batteries — ScienceDaily

The current development of stretchable battery materials that mimic the functions of nature has emerged as a highly interesting research area, necessary for the next wave of wearable electronics. A recent study, affiliated with UNIST has presented a bioinspired Jabuticaba-like hybrid carbon/polymer (HCP) composite that was developed into a stretchable current collector using a simple and cost-effective solution process. Using the HCP composite as a stretchable current collector, the research team has, for the first time, developed a highly stretchable…

Drying and dehydration—solutions to address global food shortage

Investigating retention of food nutrients during drying. Credit: University of Nottingham In the University of Nottingham Malaysia, a team of chemical and food engineers from the Food and Pharmaceutical Engineering Research Group are investigating drying and dehydration of various food materials using advance dryers. In food processing, drying plays a critical role in food preservation and safe consumption as most food products contain high moisture content which can deteriorate fast under room temperature. If food is not preserved properly, this…

Fungi can help concrete heal its own cracks

Could a secret ingredient make crumbling concrete a thing of the past? Credit: m_e_mccarron, CC BY-SA Infrastructure supports and facilitates our daily lives – think of the roads we drive on, the bridges and tunnels that help transport people and freight, the office buildings where we work and the dams that provide the water we drink. But it’s no secret that American infrastructure is aging and in desperate need of rehabilitation. Concrete structures, in particular, suffer from serious deterioration. Cracks…
