Nuclear cardiac imaging: the “old grandma” has still something to say
Ischemic heart disease (IHD) remains one of the most relevant predictors of overall patients’ mortality and a major determinant of sanitary and social costs. Different strategies have been proposed for the early diagnosis of myocardial ischemia, a
Brain imaging of the oldest old who aged successfully
The oldest old, defined as 90 years and over, is the fastest growing segment of the population worldwide. Dementia is one of the major health challenges at this age, since the risk of dementia increases steadily with
Reliable molecular imaging of bioluminescence and NIR fluorescence in vivo
In vivo molecular imaging is a powerful tool for non-invasive analysis of cellular and molecular mechanisms. Whole-body optical imaging of small animals is now widely used in preclinical research to explore disease mechanisms, evaluate drug candidates, and
Embryonic stem cells go against aging
The dream of regenerative medicine is now becoming true by the usage of versatile stem cells that are capable of differentiating into all types of cells in the body. This capability is called ‘pluripotency’ and there are
Using electrochemistry to address current needs in micro imaging
When one thinks of microscopy, usually imagined is something like a compound optical light microscope, which dates back before the 1600’s. For hundreds of years following, the optical microscope has served the scientific community by helping visualize
Routine brain MRIs may not be needed after meningioma surgery
A meningioma is a very common form of a brain tumor that tends to affect elderly patients and women. Most patients with meningiomas do not need any treatment, however, certain groups undergo surgical removal of the tumor.
Combining a range of different imaging techniques to better understand the roles metals play in biology
Microscopes in various forms have helped identify disease-causing bacteria, miniaturize microprocessors and engineer superior metal alloys. However, in biology some things remain very difficult to see even at the highest levels of magnification. Metal ions (e.g. calcium,
Resting state fMRI analysis using sparse dictionary learning in SPM framework
Brain always be active even people are in rest. In the resting period, it has been observed that particular groups of brain region are always co-activated. These regions are functionally connected each other and each group is
Genetically encoded voltage indicators for large scale cortical imaging come of age
Composed of billions of neurons, the brain is the most complex organ that dictates our daily lives. Naturally, understanding the brain is one of the final frontiers that would not only provide basic understanding but also sprout
In vivo imaging of the lung inflammatory response to Pseudomonas aeruginosa
Chronic inflammation of the airways is a central component in lung diseases and is frequently associated with bacterial infections. Monitoring the pro-inflammatory capability of bacterial virulence factors in vivo is challenging and usually requires invasive methods. The
Imaging of viruses with the help of surface plasmons
For a long time biosensors based on the surface plasmon resonance (SPR) phenomenon were not considered as effective tools to detect and visualize the binding of individual nano-scale objects to the functionalized sensor surface. However, innovative studies
Estimation of the ground bearing capacity by means of VIS-NIR, SWIR and LWIR imagery
The indiscriminate use of agricultural and forestry machines cause compaction and rutting, producing severe soil damage. When soil is compacted and/or rutted, its porosity decreases, and consequently, the amount of oxygen that is required for a healthy
To beam or not to beam: Safely scanning mouse lungs for lung disease and therapy research
Lung diseases are among the most important causes of sickness and death in the world. Chronic obstructive pulmonary disease, lung fibrosis and emphysema are examples of such devastating and life-threatening conditions. Doctors can help by relieving symptoms,
Chemesthesis affects taste
The sensations of taste, which are divisible into several distinct qualities: sweet, sour, bitter, salty, umami, and possibly fatty, play an important role for accepting or rejecting food and serve to protect us from ingesting harmful substances,
Scanning Microwave Microscopy: nanoscale imaging of material electrical properties using microwaves
In 1965 Gordon Moore estimated that the number of components on electronic chips would double every 2 years. This prediction has so far been respected. Today’s microprocessors included in our mobile phones and laptops use transistors on
