Quality control mechanism tags defective sperm cells inside the body

Defective sperm cells do not pass through the body unnoticed. A new University of Missouri study provides evidence that the body recognizes and tags defective sperm cells while they undergo maturation in the epididymis, a sperm storage gland attached to the testis.

Researchers propose consumers buy yearly 'drug licenses' as new way to pay for prescriptions

Changing the way consumers pay for prescription drugs so that the system more closely resembles paying for cell phones or computer software could increase drug use without altering patients' out-of-pocket spending, health plan costs or drug company profits, according to a new RAND Corporation study.

Researcher transplants stem cells to try to save patients' legs

A Northwestern University Feinberg School of Medicine researcher has launched the first U.S. trial in which a purified form of subjects' own adult stem cells was transplanted into their leg muscles with severely blocked arteries to try to grow new small blood vessels and restore circulation in their legs.

Genetic switches could lower cost of producing drugs, proteins

Bacteria have evolved complex mechanisms called quorum sensing systems that provide for cell-to-cell communication, an adaptation that allows them to wait until their population grows large enough before mounting an attack on a host or competing for nutrients.

Debate over safety of gene therapy trials focuses on issue of informed consent

Can a patient who agrees to participate in a safety study of a gene therapy protocol give truly informed consent and understand the risks involved when the consent forms are highly technical and the physician or institution seeking their consent has a stake in the study and its outcome?
