...urgery is a safe and well-established procedure to correct the vision loss from a cataract. In about 25 percent of cases, however, the back portion of the capsule eventually becomes clouded with a secondary cataract. Jrme notes that treatment is available for secondary cataracts, but describes it as risky ...

A unique arrangement for egg cell division

...atus that makes sure that the egg ends up with the correct number of chromosomes is a bipolar spindle consisting of protein filaments, called microtubules that are part of the cells skeleton. Spindle microtubules attach themselves to the chromosomes, separate them and pull one half out of the oocyte into a s...

New test improves detection of liver cancer

... blood test. The researchers were able to make the correct diagnosis in 70% of the cases − a success rate that equals that of the AFP tumor marker currently being used in the clinic. Promising results When the AFP test is used in combination with the new test, the accuracy of HCC diagnosis rises dr...

Teamwork between 2 key proteins necessary for normal development and regulation of red blood cells

...erapy, a normal gene can be inserted into cells to correct a genetic defect. However, according to Lloyd, in this case, the goal would be to insert a transcription factor into adult cells that would turn on an existing, silenced embryonic gene....

MIT study: Maturity brings richer memories

...he older the volunteers, the more frequently their correct answers were enriched with contextual detail. Going back to the brain scans, Ofen found that the enriched memories also correlated with more intense activation in a specific region of the PFC. We found no change with age for memories without conte...

MIT model could predict cells' response to drugs

...he signals they receive and how they arrive at the correct result. The researchers approached the problem quantitatively, measuring activity levels in five major signaling pathways after colon epithelial cells were exposed to a variety of environmental stimuli. The behavioral outcome-cell death, inflammato...

To help overcome the many challenges that stem cells bring, Dr Denning and co-investigator Professor Stephen Hill plan to engineer a novel system for real-time analysis of cardiomyocytes during early development so their properties are better...

System to analyze beating heart stem cells could lead to heart attack treatments

To help overcome the many challenges that stem cells bring, Dr Denning and his team plan to engineer a novel system for real-time analysis of cardiomyocytes during early development so their properties are better understood. The team have ...

Alternative farming cleans up water

...nt and animal production. While treatment with the correct amount of nitrogen-based fertilizer optimizes crop yield and minimizes environmental damage, too much nitrogen can lead to nitrate loss. Nitrate, a mobile form of nitrogen, escapes via water that percolates through soils. In regions where subsurfa...

Scientists take next step in understanding potential target for ovarian cancer treatment

...th the right motor complex to get the cargo to the correct destination when its needed. One of those precious cargoes is a TGF-signaling component that must get to the cell nucleus to turn on specific genes that help stop cell growth. Alterations in the TGF signaling system are known to contribute to canc...

MIT IDs mechanism behind fear

...brain cells, or neurons, form and migrate to their correct positions during early brain development. In the current work, the MIT researchers looked at how Cdk5 affects the ability to form and eliminate fear-related memories. "Remarkably, inhibiting Cdk5 facilitated extinction of learned fear in mice. This...

In the latest study, the researchers identified 101 regions of the human genome with strong evidence of very recent selection. These regions include genes that control proteins that hel...

Double identities lie behind chromosome disorders

It depends on the environmental context, which we are appreciating more and more in ecology and in biomedical research, he added. Some of these differences are small, but they can have a large effec...
