Regenerative therapies for erectile dysfunction: the influence of direct-to-consumer marketing on patient interest.

Background: Despite a lack of evidence, a number of "regenerative" therapies have become popularized treatments for erectile dysfunction (ED). Platelet-rich plasma (PRP) injections and shockwave therapy have received significant attention through direct-to-consumer marketing and are advertised as viable alternatives to guideline-backed therapies. Additionally, focused low-intensity shock wave therapy (LiSWT) has become conflated with acoustic or radial wave therapy (rWT), although their mechanism of wave generation and tissue penetration is distinct.

Rapid quantification of bacteriophages and their bacterial hosts in vitro and in vivo using droplet digital PCR.

Viruses that infect bacteria, bacteriophages (phages), are well-studied across a wide range of environments and among diverse scientific fields. Nevertheless, current methods in phage research are lacking, in part due to limitations in culturability and the lack of a universal gene marker. Here, we demonstrate that droplet digital PCR (ddPCR) can be used as a repeatable and sensitive method to study bacteria-phage dynamics both in vitro and in vivo.
