Polymorphisms of genes involved in the hypoxia signaling pathway and the development of abdominal aortic aneurysms or large-artery atherosclerosis.

Background: The pathogenesis of aortic diseases, both aneurysmal and occlusive, is associated with the occurrence of local ischemic/hypoxic conditions, but the genetic factors that differentiate the predisposition to specific types of aortic diseases are largely unknown. In this study, the functional variants in genes involved in the hypoxia signaling pathway, hypoxia-inducible factor-1α (HIF1A) 1772C>T, 1790G>A, and vascular endothelial growth factor (VEGFA) -634G>C, were analyzed in search of the associations specific to abdominal aortic aneurysm (AAA) development.

Methods: The study encompassed a series of 518 patients with AAA, 354 patients with aortoiliac occlusive disease, and 541 controls.

Purification and characterization of peroxidase from avocado (Persea americana Mill, cv. Hass).

[Gene-environment interaction for the HIF1-A 1772C>T polymorphisms and cigarette smoking increase susceptibility to abdominal aortic aneurysm].

Pathological changes in the vascular vessels, such as the presence of atherosclerotic plaques or aneurysmal dilatations, are associated with the local conditions of ischemial/hypoxia. Polymorphisms in the HIF1A gene, encoding an oxygen-regulated HIF-1 subunit (HIF-1a), determine inter-individual variability in vascular response to hypoxia. Stimulation of selected pathways, related to this response (i.

[Nutraceutical properties of lycopene].

In recent years, dietary recommendations have suggested an increase in the consumption of foods that contain phytochemicals that provide benefits to human health and play an important role in preventing chronic diseases. Lycopene -the carotenoid responsible for the red color of tomatoes- has attracted attention because of its physicochemical and biological properties in the prevention of chronic diseases in which oxidative stress is a major etiological factor, such as cancer, cardiovascular and neurodegenerative diseases, and hypertension, among others. Antioxidants, including lycopene, interact with reactive oxygen species, can mitigate their damaging effects and play a significant role in preventing these diseases.

Combined endovascular intervention and percutaneous thrombin injection in the treatment of iatrogenic pseudoaneurysm. Case report.

One of the basic techniques of treatment of iatrogenic pseudoaneurysms is percutaneous thrombin injection. Unfortunately, success rate of this treatment can be limited in cases associated with extensive damage to arterial wall. Our paper presents one case of combined treatment involving endovascular occlusion of the entry to the false aneurysm and percutaneous thrombin injection into the pseudoaneurysm chamber.

Effect of coumaphos on cholinesterase activity, hematology, and biochemical blood parameters of bovines in tropical regions of Mexico.

To assess the effect of coumaphos [O-(3-chloro-4-methyl-2-oxo-2H-1-benzopyran-7-yl) O,O-diethyl phosphorothioate] exposure on physiological responses during bovine production, acetylcolinesterase (AChE) and butyrylcholinesterase (BuChE) activities were measured in whole blood, erythrocytes, and plasma of healthy male steers (Bos Taurus x Bos indicus) sprayed with coumaphos at a non-lethal dose of 1 mg kg(- 1) body weight per day once every 14 (in vivo group) or 21 days (southern and central groups). Coumaphos topically administered at 1 mg/kg body weight per day to cattle under normal management practices in tropical areas produced a significant inhibition in erythrocyte (RBC) AChE and BuAChE activities when compared to baseline levels. RBC-AChE activity for the in vivo group decreased 71.

Location of femoral artery puncture site and the risk of postcatheterization pseudoaneurysm formation.

Iatrogenic causes constitute increasingly frequent sources of pseudoaneurysms due to endovascular interventions. However, till now, all analyses focused on evaluating different risk factors contributing to the development of pseudoaneurysm, overlooking the issue of localization of femoral puncture. The aim of this study was to assess the influence of position of femoral artery puncture on the risk of pseudoaneurysm formation.

Smoking, hypertension and several genetic factors are recognized as relevant for the pathogenesis of AAA.

The effect of soybean soapstock on the quality parameters and fatty acid composition of the hen egg yolk.

The effects of increasing proportions of soybean soapstock (SSS) in laying hen diets on egg quality parameters and on the fatty acid (FA) composition of the yolk were studied. One hundred sixty Babcock B-300 x laying hens, 20 wk of age, were allotted to 5 dietary treatments comprising a control diet (D5) with soybean oil at 100% or SSS in proportions of 25% (D1), 50% (D2), 75% (D3), and 100% (D4) replacing the oil source in commercial-type diets throughout the 15-wk laying period. Egg quality parameters were recorded weekly.
