Toward more accessible PET imaging: Miniaturizing the last step of radiotracer preparation
Positron emission tomography (PET) is a 3D body imaging method for visualizing dynamic biochemical processes in living subjects with unparalleled specificity and sensitivity. PET scans, often performed together with CT or MRI imaging, are used clinically to
High fidelity computer simulation to predict damage in advanced ceramic composites for nuclear energy
Composite materials, made from ceramic fibres within a ceramic matrix, can have excellent strength and tolerance to damage at very high temperatures. They have been chosen to protect the fuel in some future designs for advanced nuclear
Osteoporosis and erythroid cells: is there a connection?
The skeleton is an extraordinary structure paramount not only for our movement but for multiple other functions as well. Bones are dynamic organs that continuously remodel through life in a process where mature bone is removed by
What is that: a tooth with a supernumerary cusp?
Commonly, the maxillary molar has four cusps. Look at yours with each other, and you can get it. Supporting that there are more than four cusps in maxillary molar, how to diagnose it? Why did it happen?
Metabolic imaging is new a tool to investigate blood-brain barrier in Alzheimer disease
Alzheimer disease (AD) is the most common form of dementia worldwide. AD is characterized by progressive decline in cognitive functions. In the initial stages, deterioration of memory and loss of other intellectual abilities start to interfere with
Identification of drusen characteristics in age-related macular degeneration
In this study, we investigated the morphologic characteristics of drusen in order to determine their composition, using an in-vivo technique, the optical coherence tomography (OCT). The development of drusen is an important characteristic of age-related macular degeneration
What does the PROMISE trial mean for cardiac CT?
Current guidelines recommend functional testing (FT) such as exercise tests or nuclear tests (with very high radiation exposures) to identify those patients who have chest pain that may benefit from stents or bypass surgery. Unfortunately, a vast
Bush-cricket males use genital titillators to stimulate females during mating
Mating and the transfer of the sperm from the males to the females are crucial for siring offspring. If a male is unable to attract a female for mating he cannot spread his genes to the next
Computed tomography in liver cirrhosis
Liver cirrhosis is a disease with many different clinical and patho-physiological aspects, involving digestive and extra-digestive organs and systems. On the base of clinical signs and laboratory tests different scores entered in the common practice. We observed
Trifluoromethylthiolation of aliphatic electrophiles
As one of the most advanced technologies currently available for studying in vivo molecular interactions, positron emission tomography (PET) is a functional imaging technique that can produce a three-dimensional image of functional processes in the body. It
