The Future of Preimplantation Genetic Diagnosis (PGD)

Parents-to-be may consider using preimplantation genetic diagnosis (PGD) to screen embryos for inherited genetic diseases, but PGD has its limitations and cannot detect every possible condition. Here, we explore the future of PGD, and how science and technology are rapidly co-evolving to change how diseases are detected and treated at the earliest stage of life. Limitations of...

The history of preimplantation genetic diagnosis (PGD)

Today, for potential parents with genetic markers for serious hereditary conditions and diseases, conceiving a healthy child is not only possible but probable — largely due to advances in assisted reproductive technology. In particular, in-vitro fertilization (IVF) with preimplantation genetic diagnosis (PGD) can screen embryos for hundreds of different genetic diseases — greatly reducing the likelihood of passing on one of these conditions. However, this transformation in understanding genetics and reproduction is recent.

Can laser light actually pass through the skull?

A study published in Lasers in Surgery and Medicine demonstrated beneficial quantities of light can reach brain tissue using rather atypical patients--human cadavers--providing a therapeutic dose of energy-stimulating photons to diseased brain tissue. In light of new evidence, will doctors change how they treat neurological diseases?

Cadavar brains reveal NIR laser penetrates skull, scalp

While the causes of traumatic brain injury (TBI)–a bomb blast, traffic accident, or violent assault–are as diverse as the millions of individuals afflicted by the ensuing symptoms–memory loss, confusion, and personality changes–one aspect remains certain, no treatment reverses damage deep within the brain. However, scientists are challenging this conjecture by testing a a therapy whose… Continue Reading →

Laser therapy for traumatic brain injury

Mounting evidence suggests the prevelance of chronic traumatic encephalopathy (CTE) is considerably more widespread than previously believed. Now, scientists are searching for treatments that reverse the damaging effects of traumatic brain injuries before it's too late. Could NIR laser phototherapy be the solution?
