90-Plus Range Tripled Since 80s

1 Reaching 90 Years of Age More Likely

Americans are aging like never before as new census figures reveal that more people than ever are reaching age 90. The number of people in the 90-plus age category has almost tripled since 1980, reports MSNBC. The number of Americans living to 90 or older is projected to reach 8 million, or 2 percent of the population, by 2050. The golden years may not be completely golden though. The census figures show that most people living to 90 or longer have one or more disabilities, and they face a much greater risk for living in poverty compared to Americans ages 65 to 89. The growing 90-plus population is also expected to place a greater strain on Medicare and Social Security programs.

Improves Drug Delivery

2 Drug Targets Blood Vessels in Ovarian Cancer

Results from experiments in mouse models of late-stage ovarian cancer demonstrate that the compound ABT-898 shrinks tumors and prolongs survival. ABT-898 is a peptide from the molecule thrombospondin and only targets the vessels that deliver oxygen and nutrients to the tumor while leaving the healthy ones unharmed. Blood vessels are crucial in getting chemotherapy drugs to the tumor but those inside the tumor are inefficient at drug delivery so ABT-898 actually increases the delivery of other chemotherapy drugs. Getting drugs to the cancer in a better fashion prevents them from adapting fast enough to develop resistance which often plays a role in mortality. Better delivery also means lower doses of chemotherapy drugs can be used so their side effects can be minimized.
