News Medical's "Thought Leaders" series is a selection of articles written by national and
international experts and trusted advisers in the life sciences industry. All the articles are
written by experts who have been invited as recognised leaders in their fields to provide
a "state of the art" contribution.
Nanoparticles enter the organism in a number of ways. In most cases through inhalation and ingestion. When inhaled, the majority of them are expelled with the next breath. When ingested, most of them are gotten rid of through feces.
My research lab studies several classes of systems. We are mostly interested in looking at large protein assemblies to understand their structure, dynamics and how their properties relate to their malfunction in disease.
Detection of malignant skin alterations is currently aided by optical microscopes such as dermoscopes or optical microscopes. While the latter offers high resolution, it comes with a major disadvantage, just like any other purely microscopic method: it only provides a partial view of the skin due to the low penetration depth.
Jacopo Annese, President and CEO of the Institute for Brain and Society, a non-profit organization dedicated to democratizing neuroscience and making neuroscience tools and knowledge about the brain more available to the public, discusses his work on the Human Brain Library.
Before I explain the discovery, I would take a step back and explain an interesting event that takes place in the cancer cells. Normal cells follow a rapid and irreversible process to efficiently eradicate dysfunctional cells. This is a natural process by which damaged cells commit ‘suicide’. This process is known as apoptosis or programmed cell death.
“IDPs” is now a widely used acronym that stands for “intrinsically disordered proteins.” It is the term generally used by the scientific community to refer to a wide variety of proteins that do not have a stable 3D structure and are instead characterized by a high extent of local mobility, disorder and many conformers that are accessible at room temperature.
I’m a biophysicist at the University of Bordeaux and I mainly work on bio-imaging methods in the cancer laboratory research facility, mostly for brain cancers.
We started from theoretical inorganic to bioinorganic chemistry, so looking at metals in proteins, enzymes and so on. About 30% of all the proteins that we have are metalloproteins, so it’s a huge contribution that inorganic chemistry is providing for life.
We actually normally refer to this as whole-specimen imaging of breast tissue. What we mean is that when tissue is removed from the breast, which could be in the form of a lumpectomy – a breast-conserving surgery – or a mastectomy, the piece of tissue removed is relatively large.
To me the most exciting aspect of pre-clinical imaging is its broad range, from very basic science up to applied science. You deal with a range of disciplines including biology, chemistry, physics, biochemistry, biophysics, cell biology and of course medicine, as the aim is the translation of research to humans.
In our bioanalytical mass spectrometry lab we use proteomics techniques to try to understand more about Alzheimer's disease. The primary thrust of our research is that we're interested in understanding the changes that take place outside of the brain and how those correlate with what's taking place inside the brain
The main objective of our research is to improve and individualize cancer diagnostics and cancer treatment. We try to achieve this through the integrated use of MR technology and the development of data-driven tools to analyze tumors on both a functional and molecular level.
Head and neck cancers (HNC) are the sixth most common cancers worldwide, with approximately 600,000 new cases diagnosed every year.
Many Chamorro villagers on the island of Guam perished from a puzzling paralytic disease that combines aspects of ALS, Alzheimer's, and Parkinson's disease.
In around 2004, there was a Phillips paper that discussed a new imaging technique called MPI. At that time, I had an eager, promising graduate student named Matt Ferguson who wanted a project, so I asked him to take a look.
Most proteins are involved in interactions with one or a few functional ligands, but some proteins, like light chain 8 (LC8), have numerous binding partners. LC8 interacts with more than 100 functionally different proteins, from viral proteins to motor proteins to proteins involved in cell division.
I'm a professor in the Department of Integrative Structural and Computational Biology at The Scripps Research Institute. I have been performing NMR research on proteins for nearly 40 years.
I’m Björn Wängler, Professor for Molecular Imaging and Radiochemistry at the medical faculty Mannheim of Heidelberg University. I’m a radiopharmaceutical chemist by background and completed my PhD in 2004 at the University of Mainz.
Flow Cytometry, the measurement of various cellular characteristics as they flow through a measuring apparatus, has so many applications that it's hard to know where to begin.
Single fluorescent molecules provide a local nanometer-sized probe of complex systems. We can measure the motion of the single molecule, use them to achieve imaging on a scale down to 20 nanometers, or we can infer aspects of the behaviour of the object under study by the details of the light that is emitted.
