Cervical, vaginal cancer higher in women previously treated for pre-cancerous cells on cervix, study finds

Cytology screening to prevent cervical cancer is a medical success story and examinations have proven to be an effective way to reduce deaths from cervical cancer. However, the risk of cervical cancer is not eliminated when abnormal cells are detected and removed and as such women are asked to participate in follow-up programs. No prior study has investigated how aging affects the risk of death from cervical cancer after treatment of CIN3. Researchers from Sahlgrenska University Hospital and Karolinska Institute in Sweden therefore aimed to investigate how age affected this risk…

Capturing a hard-wired variability: What makes some identical twins noticeably different?

"We have captured a fundamental randomness at the level of gene expression that has never before been described — one that persists throughout development and into adulthood," says Ludwig scientist Rickard Sandberg at the Karolinska Institutet in Sweden. The discovery was made possible by a powerful new technique developed by Sandberg’s lab for analyzing the global expression of genes in single cells. With the exception of a subset of genes found on sex chromosomes, every mammal inherits one copy of every gene from each of its parents. Each of those copies is known as an allele, and alleles often differ measurably from their genomic siblings — a fact that accounts for a good deal of human and animal diversity…
