Is the amount of coronary perivascular fat related to atherosclerosis?

Interesting and stimulating data about the effect of the perivascular adipose tissue size on atherogenesis are based mainly on CT findings. We studied this topic by directly analyzing perivascular adipose tissue in explanted hearts from patients undergoing transplantation. Ninety-six consecutive patients were included, including 58 with atherosclerotic coronary heart disease (CHD) and 38 with dilation cardiomyopathy (DCMP).

Focal histopathological progression of porcine experimental abdominal aortic aneurysm is mitigated by atorvastatin.

Aim: Observational studies in human patients and animal experiments suggested that statins have a potential in slowing the growth of small abdominal aortic aneurysms (AAA). Our aim was to quantify histological postoperative changes of AAA in porcine experimental model of AAA with and without administration of atorvastatin.

Methods: The AAA was induced by intraaortic infusion of porcine pancreatic elastase and subrenal application of plastic cuff.

Vascular histopathologic reaction to pulmonary artery banding in an in vivo growing porcine model.

Pulmonary artery banding (PAB) is used as a surgical palliation to reduce excessive pulmonary blood flow caused by congenital heart defects. Due to the lack of microscopic studies dealing with the tissue remodeling caused by contemporary PAB materials, this study aimed to assess histologic changes associated with PAB surgery by analyzing local tissue reaction to the presence of Gore-Tex strips fixed around the pulmonary artery. Gore-Tex strips were used for PAB in a growing porcine model.

Asymptomatic abdominal aortic aneurysms show histological signs of progression: a quantitative histochemical analysis.

Objective: Abdominal aortic aneurysm (AAA) is a serious disease due to its covert nature, relatively high prevalence and fatal prognosis in the case of rupture. To obtain new insights into AAA pathogenesis, we examined the relationships between histopathology, multiplex in vitro immunoassay data, diameter and symptomatology.

Methods: In a prospective, non-randomised study, we evaluated samples from 6 normal infrarenal aortae and 65 AAA patients (65 walls, 55 thrombi).

Dual inoculation with mycorrhizal and saprotrophic fungi applicable in sustainable cultivation improves the yield and nutritive value of onion.

The aim of this paper was to test the use of dual microbial inoculation with mycorrhizal and saprotrophic fungi in onion cultivation to enhance yield while maintaining or improving the nutritional quality of onion bulbs. Treatments were two-factorial: (1) arbuscular mycorrhizal fungi (AMF): the mix corresponding to fungal part of commercial product Symbivit (Glomus etunicatum, G. microaggregatum, G.
