Effect of endogenous and exogenous enzymatic treatment of green vanilla beans on extraction of vanillin and main aromatic compounds.

Endogenous and exogenous enzymatic hydrolysis carried out to obtain vanilla extracts with higher concentrations of vanillin using green vanilla beans. Sequences initiated with freezing of green vanilla beans at - 1 °C for 24 h, followed by endogenous hydrolysis under optimal β-glucosidase activity at 4.2 and 35 °C for 96 h, exogenous hydrolysis with Crystalzyme PML-MX at pH 5.

Comparison of the Kois Dento-Facial Analyzer System with an earbow for mounting a maxillary cast.

Statement Of Problem: The Kois Dento-Facial Analyzer System (KDFA) is used by clinicians to mount maxillary casts and evaluate and treat patients. Limited information is available for understanding whether the KDFA should be considered as an alternative to an earbow.

Purpose: The purpose of this study was to evaluate maxillary casts mounted using the KDFA with casts mounted using Panadent's Pana-Mount Facebow (PMF).

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).

Background: Avocado (Persea americana Mill, cv. Hass) fruit ranks tenth in terms of the most important products for Mexico. Avocado products are quite unstable due to the presence of oxidative enzymes such as polyphenol oxidase and peroxidase.

[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.
