Benefits of Biomarkers in Colorectal Cancer Treatment

Biomarkers fall into different categories: diagnostic biomarkers, are used to identify a disease; prognostic biomarkers, help clinicians to determine, for example, whether you're more likely to die or have problems with a disease; and there are some that can be used to inform treatment, to determine whether one therapy would be more successful than another.

Analytical Science in Precision Medicine

Pittcon is an analytical conference, so naturally my talk will be about analytical chemistry and how analytical chemistry will become increasingly important in delivering healthcare solutions, not only for rich people, but also, hopefully, for poor people across the world.

Optical microscopy resolution revolution

I will talk about the simple but fundamental idea that allowed breaking the diffraction barrier in fluorescence microscopy as well as about MINFLUX nanoscopy, the latest development in the field that for the first time provides true molecular resolution with visible light and standard objective lenses.

Preclinical research using 1 Tesla desktop MRI

I'm an MR imaging scientist in the preclinical field. I'm a team leader of the functional and molecular imaging team at the National Institute of Radiological Sciences (NIRS) in QST.

Understanding the rise in NTM infections

It is important to keep in mind that nontuberculous mycobacteria are environmental, and so unlike mycobacterial tuberculosis, generally this is not a person to person transmitted disease. The organisms are found universally in water and soil and so most people are exposed on a daily basis.

Counteracting premature aging

Aging is the continuing process of such stress exposures, and with advancing age (normal aging), we must carry lots of senescent cells within our bodies. Senescent cells also often provide some ‘bad influences’ to surrounding healthy cells; such as chronic inflammation and tumorigenesis

Genetic test to predict IBD severity in children

Inflammatory bowel disease (IBD) is a chronic relapsing inflammation of the gastrointestinal tract with abdominal pain and diarrhea being the most common symptoms. It can be challenging to diagnose as gastrointestinal complaints mimicking IBD are common.

Could the mTOR pathway be used to protect against cancer?

The mTOR pathway is probably the main pathway in humans and other animals that drives growth. That is, the accumulation of mass and adding mass to make an organism bigger by both making more cells, and making cells grow and become bigger.

Could a blood test predict how cancer spreads in children?

Traditionally, we use biopsies to try to predict how cancer spreads. There are a number of molecular markers that are used, but biopsy is a limited approach. Now, the current trend is to use liquid biopsy, which is basically a blood sample.

Can liver damage caused by a low protein diet be repaired?

Proteins are an important component of our diet and help to build muscles; they take part in the structure of hormones and they are vital to the whole body’s metabolism. The most important consequence is that the liver loses its capacity to produce proteins (such as albumin) and to metabolise (inactivate or activate in some cases) medicaments for instance.

Analyzing single-cell RNA data in pre-malignant tumors

RNA sequencing is basically the isolation of RNA from cells and the use of reverse transcriptase to turn the RNA into DNA. You can then use your standard DNA sequencing technologies to quantify the cDNA that you obtained from the reverse transcription reaction.

Using nanodiamonds to see smaller

Many of the most fundamental, life governing biological processes take place at size and time scales that remain invisible with current imaging technologies. Understanding how the molecules that underlie these processes move, interact and change could pave the way for new treatments, cures and the development of novel drug therapies.

Benefits of compact MRI

The kind of research I'm interested in is a technique called diffusion MRI and this technique is sensitive to the microstructure of the tissue. Particular clinical applications that it is used for are cancer and looking at neurodegenerative diseases.

Advances in optogenetics

Optogenetics is a way of introducing information into the brain using light, it targets specific cells or connections across the brain. It is fast, like brain signaling, and helps you communicate with neural circuitry in a language more similar to what is normally used within the brain.

Using spherical nucleic acids to track and treat disease

Spherical nucleic acids are structures that are made by taking a nanoparticle template and using chemistry to arrange short strands of DNA or RNA on the surface of those particles. The spherical core of the nanoparticle creates a spherical arrangement of DNA or RNA, similar to tiny little balls of nucleic acids.

Decoding the exposome through breath biomarkers

The human exposome is probably best defined as “everything that is not the genome.” This is a bit tongue in cheek, but basically, the exposome is comprised of all of the chemicals in your body from the environment, food, consumer products, their metabolites, the endogenous “housekeeping” chemicals, the cellular wastes from energy production, as well as all of the messenger compounds and life supporting chemicals.

Routine small animal MR imaging using the ICON

I’m an Assistant Professor at the Department of Biochemistry and Molecular Biology of the Complutense University, Madrid. Until five years ago I had been working here at the university, part time with a private clinic, where I worked in MRI and MR spectroscopy for clinical applications.

Targeting RNA repeats

RNA repeats are stretches of code in the body that incrementally repeat. For example, in the most common cause of adult-on-set muscular dystrophy a RNA has a repeat of r(CUG) and this three letter code can repeat thousands of times.

Carving a career in science

I was interested in a whole range of subjects, but the one that really grasped me from a young age was biology and, in particular, human biology. I was really fascinated with how the human body worked and I still am; that's something that has stayed with me.

Exosome isolation using ultracentrifugation

In the outpatient clinic and in the laboratory our current research studies aim at understanding the mechanisms of release and clearance and the biological functions of exosomes and membrane particles in the plasma of individuals who develop emphysema, a form of chronic obstructive pulmonary disease characterized by enlargement of airspaces and loss of alveoli.
