At 18, Katie Stubblefield lost her face. At 21, she became the youngest person in the U.S. to undergo the still experimental surgery. Follow her incredible story.
There are three types of skin cancer, two of them, namely basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are classified as the non-melanoma type. The melanoma type on the other hand, refers to cancer cells that disrupt the function of the melanocytes, the mature melanin-produ...
Doctors use tissue or cell samples taken from biopsies to learn disease information, such as cancer type. Thanks to the near immediate analysis of cancer tissue, surgeons know whether they are cutting healthy or cancerous tissue during the surgery. This information produces a clear tumor outline ...

Once master regulators were identified using BENEIN, the team validated their role using computer simulations and experimental “knockdowns” where the gene is essentially turned off in cancer cell lines. They found that by targeting master regulators, they were able to reprogram cancer cells by ...
The hyper-methylation of CpG islands as well has a quieting effect on miRNAs in cancer. Notably, miRNAs are concise, non-coding RNAs (18–22 nucleotides in lengthy) that adjust a number of cellular activations, such as cell multiplication, apoptosis and segregation by quieting special target ...
This can lead to health effects like skin cancer [source: EPA]. X-rays: X-rays are very high-energy light waves. We're most familiar with their use in a doctor's office, but X-rays also naturally occur in space. But don't worry, X-rays can't penetrate from outer space to the ...
Magnetic lines of force, or flux, are measured in Webers (Wb). In electromagnetic systems, the flux relates to the current. A field's strength, or the density of the flux, is measured in tesla (T) or gauss (G). One tesla is equal to 10,000 gauss. You can also measure the field...
It adds protocol overhead in the form of the notorious ATM "cell tax", which adds additional cost to the OLT and ONUs. When using ATM in any architecture, 5 bytes of bandwidth are wasted for every 48-byte segment, creating an onerous overhead. By con- trast, Ethernet happens to be ...
ABCG2 was initially named the breast cancer resistance protein, but three laboratories, including the aforementioned, vied to clone ABCG2 from the placenta as well as a mitoxantrone-resistant colon carcinoma cell line. Additional ABCG2 names were the placenta-specific ATP-binding cassette ...
