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
