Inside Clinuvel: effective drug development

Tuesday, July 31st, 2012

Take ten years, half a billion dollars and countless man hours from some of the most highly trained, intelligent individuals on the globe. You still stand a 90% chance of failure, some of which is totally out of your control. This is the apparent reality of modern drug development.

With the odds so stacked against it, it’s little wonder that the drug development sector is one requiring constant evolution in rethinking how to survive. In addition to the ‘regular’ risks of drug development, turmoil in global markets since 2007 has seen risk adverse investors shun drug development and biotechnology stocks for blue chip companies which are perceived as safer. The pressure to perform has increased for those companies who continue to work in the space.

In short, it’s forced even greater creativity to ensure survival and prosperity. (more…)

Hang in there! Take back control! (Part 2)

Monday, February 27th, 2012

We recently invited Richard Roosenboom to share his experiences as a parent of a child with a rare disease. In the coming weeks we will publish part of the Roosenboom’s story in a four post series. In part one of this post Richard described the onset of Simone’s disorder and the road to the diagnosis Hydroa Vacciniforme (HV) some months later.

Our local hospital learned about Simone’s diagnosis with HV and invited us to discuss her condition. They felt that the diagnosis needed confirmation by tests. Yet, as HV itself cannot be confirmed by tests, that meant that Simone would have to undergo a series of examinations to exclude other diseases and disorders. They felt that the diagnosis of HV could be accepted only if all others had been excluded. We learned about some tests being quite painful and harmful to Simone’s skin and took control again: we refused. We decided to accept her having HV and not having her undergo such an ordeal, knowing that even if HV was confirmed, it would change nothing. (more…)

Hang in there! Take back control! (Part 1)

We recently invited Richard Roosenboom to share his experiences as a parent of a child with a rare disease. In the coming weeks we will publish part of the Roosenboom’s story in a four post series. You can read the first post here: Too rare to diagnose: Hydroa Vacciniforme.

In 2003 our daughter Simone (then almost six years old) was diagnosed with Hydroa Vacciniforme (HV) by a leading Dutch dermatologist with over 35 years of experience. He listened carefully to our story, retreated for a moment to think and consult some books, and then came back and pointed out the page in a book where HV was described. He had never seen it in his life! After over three months Simone’s illness finally had a name and a history, and we felt like having a future again. (more…)

Too rare to diagnose: Hydroa Vacciniforme

Friday, February 17th, 2012

We recently invited Richard Roosenboom to share his experiences as a parent of a child with a rare disease. In the coming weeks we will publish part of the Roosenboom’s story in a four post series.

This year, 2012, sees calendars with February 29th: a rare day that is only seen once in every four years. Thus it is logical that this day is chosen as the worldwide Rare Diseases Day: a day where extra attention is sought for many rare diseases and disorders from which adults and children suffer every day.

Often the causes of rare diseases aren’t known. There’s often no treatment (yet). That’s why the world needs Rare Diseases Day: to show that these patients too are entitled to care and treatment, like any other. (more…)

Top five sun and skin myths (part 1)

Thursday, February 2nd, 2012

There are a number of misconceptions about the interaction between sunlight and skin. In this two part post we look at what we think are the top five most common sun and skin myths.

Myth 1: I can’t get sunburnt on a cloudy day (more…)

Photoaging

Thursday, December 22nd, 2011

Young adults are the age group most likely to seek a tan, with research showing that people under the age of 29 – particularly women – are tanning most frequently, both in the sun and under solariums. Aside from the well-recognised risks of skin cancer, there is another consequence of this increased exposure to ultraviolet (UV) radiation of which many teens are not aware – photoaging. In short, all this UV exposure over time makes skin look older. (more…)

Sun protection: Appearance is a greater incentive than health for young people

Monday, November 21st, 2011

According to the U.S. Preventative Services Task Force (USPSTF), the best way to deter teens and young adults from overexposure to the sun is to demonstrate the effects ultraviolet (UV) radiation can have on their appearance.

The USPSTF, an independent panel of experts assigned to provide recommendations on an array of health prevention issues, looked at evidence indicating behavioural counselling could help to prevent skin cancer. The newly released recommendations, an update of the 2003 statement, suggest that teens’ behaviour can indeed be changed through counselling; particularly that which highlights the physical changes UV radiation causes to skin, such as premature aging and wrinkling.

Ultraviolet A more cancer-causing than once thought

Tuesday, October 18th, 2011

While the evidence linking sunbeds to the development of skin cancer continues to mount, recent research provides new insight into the underlying mechanisms.

Radiation from both the sun and tanning beds is made up of various wavelengths, including visible light and several types of ultraviolet (UV) radiation. Ultraviolet B (UVB) rays, those which cause sunburn, have long been heralded the culprit which initiates skin cancer. It does this by damaging the genetic information (DNA) within skin cells, forming lesions known as cyclobutane pyrimidine dimers (CPDs) and pyrimidine (6-4) pyrimidone photoproducts (6-4PPs). These lesions create mutations in the DNA which can lead to the development of skin cancer (you can read about this process here). (more…)

Ultraviolet radiation and its effects on the skin

Wednesday, June 22nd, 2011

Ultraviolet (UV) radiation forms part of the electromagnetic spectrum between visible light and X-rays; it is invisible to the human eye. UV light can be separated into three bands, UVA (400-320nm), UVB (320-290nm) and UVC (290-100nm). Of the UV radiation that reaches the Earth’s surface from the sun, approximately 6% is UVB and 94% UVA.

Skin maintains a curious balance with UV radiation. When UV impacts upon skin, the various wavelengths of light penetrate to different levels and thus have a number of effects.

Cellular messaging leading to melanin production

Tuesday, June 7th, 2011

Each cell within the body has one or more receptors; molecules on or within the cell to which other molecules, called ligands, bind. This binding causes a series of chemical reactions within the cell, called a ‘signaling pathway’. Signaling pathways are responsible for cellular responses, allowing other cells and external elements to alter how a cell functions. There are two types of ligands which bind to receptors: agonists, which then promote a response in the pathway, and antagonists, which lead to an alternate response. (more…)
