Tissue engineering: how to grow a bypass

23/04/2018

A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.

Myocarditis: more specific diagnosis thanks to molecular imaging

01/09/2017

There are many causes of myocarditis or inflammation of the heart muscle. Oftentimes, the culprits are viruses or bacteria and sometimes even an acute heart attack. Regardless of the cause, it creates a challenge for cardiologists: a diagnosis tends to be only nonspecific without a biopsy. A cardiac MRI and molecular imaging promise to provide assistance.

Sodium intake and blood pressure: too much salt is bad for you. What about too little salt?

01/12/2016

Common salt – or sodium chloride – is essential as a stimulant for nerve conduction. What is more, sodium ions also regulate the water balance in the body. Yet when it came to salt consumption, for the longest time the rule was "less is more". However, a recent study publication calls this belief into question.

Cardiac insufficiency: early diagnosis with ultrasound

02/05/2016

Heart failure or cardiac insufficiency presents an extra strain on patients because it severally limits everyday performance and deprives them of energy. Due to their intense need for movement, children are particularly strongly affected. However, the disease is frequently not detected until the physical performance is already declining. An early diagnosis could prevent this.

Wanted: rapid test to prevent deep vein thrombosis

01/07/2015

Deep vein thrombosis is not just a risk factor for frequent flyers but also for wearers of cardiovascular implants and newly operated patients. Blood thinners prevent these dangerous blood clots from forming, but they need to be carefully adjusted and do not work the same way in every patient. A detailed analysis of platelets (thrombocytes) could prevent complications in the future.
