Main effects of ascorbic acid levels and organic acid type on physicochemical properties, microbial populations, texture, and biogenic amine formation in sucuk

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Sucuk is a traditional Turkish dry fermented sausage, the quality and safety of which depend on physicochemical, microbiological, and biochemical changes during fermentation and ripening. Organic acids, their salts, and antioxidants such as ascorbic acid (AA) are widely used in fermented meat products; however, information about ...

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]

, 2013
Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...

Analysis of the Matrix Metalloproteinases Family Profile in Gastric Cancer Suggests Key Matrix Metalloproteinases for Tumor Development and Their Clinical Impact

Molecular Carcinogenesis, EarlyView.
ABSTRACT Gastric cancer (GC) is the fifth most common type worldwide, representing a public health problem. Among the genes related to this tumorigenesis, the family of matrix metalloproteinases (MMPs), essential regulators of the extracellular matrix (ECM), stand out for their involvement in the development and progression of GC.
