Cell transplant may help heart after spinal cord injury
Researchers tested transplanting immature nerve cells into spinal cord injuries in rats. The transplants improved nerve control of circulation — stabilizing resting blood pressure and lowering heart rate — but hormonal responses after injury still rose.

Untreated Sleep Apnea Speeds Heart Aging and Raises Death Risk
A laboratory study using a long-term mouse model finds that untreated obstructive sleep apnea — recreated by repeated drops in oxygen during sleep — leads to faster cardiovascular aging and higher mortality. Researchers call for early screening and treatment.

Biodegradable patch may help heart heal after heart attack
Researchers report a biodegradable microneedle patch that delivers interleukin-4 to injured heart tissue. The local treatment encourages healing immune cells, reduces scarring, and may improve heart recovery while avoiding systemic side effects.
