Hepatitis C (HCV) testing for baby boomers: an interview with Dr. Donald Jensen, Director, Center for Liver Diseases, University of Chicago

The USPSTF agreed with the CDC that since most patients (75%) who are currently infected with hepatitis C were born between 1945 - 1965, and since risk-based screening has not been successful in identifying these individuals, that a one time age-based hepatitis C blood test was necessary.

Gout, uric acid levels and risk of death: an interview with Professor Austin Stack, Graduate Entry Medical School, University of Limerick

Gout is a relatively common arthritic disease that affects about 4% (I in 25) of the population. It results from the deposition of uric acid in joints due to elevated blood levels and a resulting inflammation ensues which is very painful.

Child cancer survival: an interview with Prof Kathy Pritchard-Jones, University College London

Back in the early 1960s, just before chemotherapy really started to be used, only about 30% of children survived cancer. That was mainly because they had cancers that were amenable to surgery.

p53 and cancer research: an interview with Professor Sir David Lane, Scientific Director of the Ludwig Institute for Cancer Research

P53 is a tumor suppressor gene. The gene encodes for a protein that monitors the state of the cell. If something goes wrong, it stops the cell from dividing or causes the cell to commit suicide. I call it the “guardian of the genome” as it is the molecule that seems to keep cells normal. It is one of our big defenses against cancer.

Human filariasis research: an interview with Professor Mark Taylor, Liverpool School of Tropical Medicine

Filariasis refers to a group of diseases caused by parasitic worms, which are transmitted by blood feeding insects. Two species infect the lymphatic and blood systems causing lymphatic filariasis, which in some people can lead to gross swelling of the limbs and 'elephantiasis'.

Long-term cannabis use, dopamine and motivation: an interview with Dr Michael Bloomfield, Department of Medicine at Imperial

We classified ‘long-term’ cannabis use as being regular, at least weekly, cannabis use for over 12 months. This is the period of time that’s used in the DSM-IV psychiatric diagnostic manual to classify substance use disorders. In our study the average duration of at least weekly use was just over four and a half years.

White blood cells and the spread of cancer: an interview with Drs. Lorenzo Ferri and Jonathan Cools-Lartigue, McGill University

As surgeons who take care of cancer patients, we have observed a troubling association between patients who suffer from infections after surgery and the rapid spread of their cancer. We have reported this in lung cancer patients, and others have made these observations in a variety of different cancers. However, the mechanisms responsible for this association are still poorly understood.

Coffee and appetite: an interview with Matt Schubert and Associate Professor Ben Desbrow, Griffith University

We wanted to do something a bit different than the “typical” work on caffeine and exercise, and I have considerable interest in appetite regulation, so we built up from there.

Semi-quantitative pregnancy tests: an interview with Dr. Paul Blumenthal, Stanford University School of Medicine

Regular pregnancy tests work a little bit like a simple light switch that you have on your wall. It’s either on or off. When it’s on, that means the test is positive; if it’s off, obviously, it’s negative.

Immunization in developing countries: an interview with Dr. Jos Vandelaer, Chief of Immunization for UNICEF

Overall, worldwide, immunization programs reach around 83% of all children – this is an enormous achievement. With this level of immunization coverage, we prevent over 2 million deaths, year after year. This statistic is often forgotten or taken for granted.

Robotic retroperitoneal lymph node dissection (RPLND) for testicular cancer: an interview with Dr. Stephen Williams of St. Joseph Hospital in Orange

Robotic RPLND utilizes laparoscopy combined with robotic technology to perform dissection and removal of lymph node tissue in the retroperitoneum both as a staging as well as therapeutic procedure for patients with testicular cancer.

Osteoarthritis associated genes: an interview with Professor Jonathan Tobias, University of Bristol

Joints are lined by articular cartilage, loss of which is one of the hallmarks of osteoarthritis. Articular cartilage is made up of a number of proteins, such as type II collagen. In rare forms of osteoarthritis, one of these structural proteins is defective as a result of a genetic mutation.

Curing type 1 diabetes: an interview with Dr. Habib Zaghouani, MU School of Medicine

Type 1 diabetes is an attack by the immune system of the islet of Langerhans within the pancreas. Basically, the islet of Langerhans harbor beta cells, which produce insulin and when the islets are attacked, the beta cells destruct and there is no more insulin. When the insulin level goes low, blood glucose levels go high and that creates a problem.

Controlled drug release using novel excipients: an interview with Dr Laura Waters, University of Huddersfield

When you take a medicine you may want the drug to all be released immediately or perhaps more slowly over a longer period of time. If we can make a medicine where we control the release then we can tailor our medicines to release at the exact rate we choose that is best for the patient.

Sentinel lymph node biopsy for early breast cancer: an interview with Prof. Gordon Wishart, Anglia Ruskin University

Our current method, which is recommended by the Association of Breast Surgeons in the UK, involves the use of injections of blue dye and radioisotope to identify the first node(s) under the arm (axilla) called the sentinel nodes.

Bioapplications of nanoparticles: an interview with Dr Catherine Berry, University of Glasgow

These particles are all classed as inorganic particles, which can all be utilised in biomedical applications. They differ in terms of their inherent material and size dependent physiochemical properties, for example, their optical and magnetic properties.

Malaria control strategies: an interview with Sir Richard Feachem, Global Health Group, University of California, San Francisco

Exciting progress has been made in the global fight against malaria. The malaria map continues to shrink each year; in the last ten years four countries have been certified malaria-free, and thirty-four additional countries are now working towards malaria elimination targets.

Tumor suppressor p53 inactivation and restoration: an interview with Dr. Xin Lu, Ludwig Institute for Cancer Research

Before we talk about p53, it is important to understand why cancer cells are a problem for the body. Cancer cells multiply recklessly, refuse to die and blithely metastasize to set up shop in places where they don’t belong.

Prostate cancer and DNA: an interview with Dr. Jianfeng Xu, Wake Forest School of Medicine

Prostate cancer development is associated with both inherited and acquired genetic alterations. More than 70 inherited genetic variants have been consistently identified in human DNA that may contribute to susceptibility or risk of prostate cancer.

BMI and fast food: an interview with Dr Lorraine Reitzel, Assistant Professor, Department of Health Disparities Research at MD Anderson

This project was a secondary project that came out of a longitudinal cohort study that we've been conducting with the Windsor Village United Methodist Church in Houston Texas, which is a large, primarily African American mega-church with over fifteen hundred congregation members.
