Penelitianbegini, sekarang ini, lazimnya dilakukan di negeri kafir olehorng
Orang Islam mah lebih suka buang-buang waktu untuk tunggang tunggik kayak onta
dientoin jirapah lima kali sehari; buang-buang duit untuk naik haji sembari
muter-muter kayak orang gila di Makkah dan berebut melempar setan yang nggak
ada di padang pasir sono.; atau bikin onar dan saling berbunuhan seperti di
Afghanistan, Iraq, ¨Pakistan, Aljazair, Daarfur dll....
Islam itu, saya bilagn dan saya ulang, adalah laknat buat umat manusia artinya
juga buat orang Islam sendiri.
Window into cancer-spread secrets
A technique which literally places a window in a mouse's chest could help
scientists unlock cancer's most mysterious and deadly process.
US scientists were able to keep a mouse alive for 21 days with the tiny piece
of glass in place.
During that period they could watch cells from a breast tumour as they spread
to other tissues, reports the journal Nature Methods.
Cancer Research UK said it could unlock ways to stop this spread in humans.
This cutting-edge research provides new opportunities to study the complex
relationship between cancer cells and their surrounding tissue

In many cancers, it is not the initial tumour that kills - the danger rises as
bits of it break away and travel to other parts of the body.
However, what triggers this process, called metastasis, is still poorly
This is partly because it is impossible to watch metastasis in action. The
behaviour of cancer cells in a laboratory dish may be radically different from
their behaviour in living tissue.
The team from the Albert Einstein School of Medicine in New York, has been
hunting for ways to allow scientists to view metastasis in the body.
Their earlier attempts involved peeling back a flap of skin on the mouse's
chest so that the microscopic activity could be seen directly.
However, metastasis happens over days or even weeks, and the mice could not
survive under anaesthetic for this long. In addition, conditions in the open
wound were far drier than inside the body.
Their new technique involves inserting the glass "coverslip", which means the
mouse can live - and the cancer cells observed - for much longer, with the
"micro-environment" surrounding the tumour kept intact.
Then cancer cells were marked with substances which allowed their movements to
be tracked under the microscope.
This approach is already reaping its rewards - they found that subtle changes
to this "micro-environment" seemed to create the right conditions for cancer
cells to begin their journey away to other parts of the body.
Dr Joanna Peak, Cancer Research UK's science information officer, said:
"Tackling metastasis remains one of the biggest challenges in successfully
treating cancer, but it's also one of the most difficult elements of cancer to
study in the laboratory.
"This cutting-edge research provides new opportunities to study the complex
relationship between cancer cells and their surrounding tissue - to help us
understand metastasis in more detail."
