Farming fish in the sea will not nourish the world.

Recent literature on marine fish farming brands it as potentially compatible with sustainable resource use, conservation, and human nutrition goals, and aligns with the emerging policy discourse of 'blue growth'. We advance a two-pronged critique. First, contemporary narratives tend to overstate marine finfish aquaculture's potential to deliver food security and environmental sustainability.

Patch-pump technology to manage type 2 diabetes mellitus: hurdles to market acceptance.

The recent development of novel "patch"-type insulin infusion pump (IIP) technologies has created an opportunity to improve the quality of life for a broader type 2 diabetes patient demographic. At first glance, type 2 diabetes patients represent a large percentage of the total diabetes patient population; however, adoption of traditional IIP products and multiple daily injection (MDI) therapy has remained limited amongst this patient segment. With an insulin reservoir, delivery system, and cannula integrated into a small, wearable, disposable or semidisposable device, patch pumps simplify traditional IIP therapy, while potentially offering therapeutic benefits over traditional MDI therapy.

Convergence of continuous glucose monitoring and in-hospital tight glycemic control: closing the gap between caregivers and industry.

The convergence of continuous glucose monitoring (CGM) and tight glycemic control protocols is approaching. As with the diffusion of any innovative technology, there will be challenges that will likely delay widespread adoption. With the objective of assessing the current mindset of health care professionals toward CGM adoption in the hospital intensive care unit (ICU) setting and resulting implications to industry, Boston Biomedical Consultants surveyed >60 U.

Update on gene therapy for intimal hyperplasia.

Trauma to the vessel wall leads to smooth muscle cell (SMC) activation and eventual intimal hyperplasia. This process occurs in restenosis following balloon angioplasty, particularly with stent placement, occlusion of vascular bypasses, and arteriopathy of chronic allograft rejection. Genetic interventions affecting the cell cycle or early postinjury events have been successful in limiting SMC proliferation in vitro and in animal models.

New, angle-independent, low cost Doppler system to measure blood flow.

Background: A new Doppler flowmeter using a special transducer forming two ultrasound beams to insonate vessels was developed. This low-cost flowmeter allows the flow to be measured independently of the angle of insonation.

Methods: Sixty-five flow determinations were made in the carotid arteries of five pigs.
