Early Gene Changes Identified That Precede Blood Cancer

DNA samples have been used to uncover early, precancerous genetic changes in the blood that are linked to increased chances of developing blood cancers such as leukemia, lymphoma or myelodysplastic syndrome.   More...

Noninvasive Test for Endometriosis Developed

Endometriosis is diagnosed and staged at surgery, resulting in an 11-year latency from symptom onset to diagnosis, underscoring the need for less invasive, less expensive approaches.   More...

Nanoflares Detect Live Tumor Cells in Human Blood

Metastasis portends a poor prognosis for cancer patients and primary tumor cells disseminate through the bloodstream before the appearance of detectable metastatic lesions.  More...

Sickle Cell Trait Linked to Chronic Kidney Disease Risk

Sickle cell trait is defined as inheritance of a single copy of the sickle mutation that results from a single base pair substitution in the gene encoding the β-globin chain of hemoglobin.   More...
