OBJECTIVE We aimed to determine the safety and efficacy of biobasorbable magnesium alloy stents in porcine coronary arteries. Bioabsorbable magnesium stents carry the potential to overcome the limitations posed by permanent metallic stents such as chronic inflammation, late stent thrombosis, prolonged antiplatelet therapy, and artifacts when imaged by(More)
Health-promoting properties such as antioxidative, anticarcinogenic, and cholesterol-lowering effects are described for mangiferin and hesperidin, the major phenolic compounds present in Cyclopia genistoides (honeybush). However, knowledge of their metabolic fate and their absorption from the gastrointestinal tract is very limited. The aim of this study was(More)
Oral infection with enterohemorrhagic Escherichia coli (EHEC) may cause severe enteritis, followed in up to 10% of cases by an extraintestinal complication, the hemolytic uremic syndrome (HUS). HUS is characterized by a triad of symptoms: anemia, thrombocytopenia, and acute renalfailure due to thrombotic microangiopathy. EHEC produces several virulence(More)
BACKGROUND As warm ischaemic damage is a major reason for the loss of donor organs, an experimental study was performed in order to evaluate retrograde oxygen persufflation (ROP) as a method to extend the warm ischaemic tolerance of kidneys. METHODS Kidneys of 32 pigs were exposed to warm ischaemia for 60, 90 or 120 min. Then, 16 kidneys were subjected to(More)
BACKGROUND Surgical reapposition of peripheral nerve results in some axonal regeneration and functional recovery, but the clinical outcome in long distance nerve defects is disappointing and research continues to utilize further interventional approaches to optimize functional recovery. We describe the use of nerve constructs consisting of decellularized(More)
Synthetic or biological patch materials used for surgical myocardial reconstruction are often fragile. Therefore, a transient support by degradable magnesium scaffolds can reduce the risk of dilation or rupture of the patch until physiological remodeling has led to a sufficient mechanical durability. However, there is evidence that magnesium implants can(More)
Aspalathin, a dihydrochalcone and C-glycoside, is the most abundant flavonoid in rooibos (Aspalathus linearis), which is well known as an herbal tea in many countries. Aspalathin appears to have in vitro antioxidative and antimutagenic effects. To understand the effects of aspalathin in the body, research on the absorption in the intestinal tract,(More)
In Europe, Streptococcus suis serotypes 2 and 9 are very important causative agents of meningitis, arthritis and septicemia in piglets. So far, no vaccine has been described which elicits protection against both serotypes. The working hypothesis of this study was that an isogenic serotype 2 mutant attenuated in virulence but not in colonization of the(More)
Streptococcus suis causes numerous diseases in pigs, most importantly, meningitis, arthritis, septicemia, and bronchopneumonia. One of the major problems in modern swine production is the lack of a vaccine protecting against more than one S. suis serotype. The objective of this study was to determine the protective efficacy of a serotype 2 murein-associated(More)
