Mechanical Transmission of Cassava Brown Streak Virus
Nature, 1959BROWN streak virus disease of cassava (Manihot utilissima Pohl.) is important in all the cassava-growing areas on the coasts of Kenya and Tanganyika, because necrosis of the starch storage tissues of the roots and stems of infected plants results in serious losses in yield1,2.

A Gas-Mechanical Coupled Hoek-Brown Criterion
2020A gas-mechanical coupled constitutive equation is developed for coal containing gas or CO2 to predict the failure behavior based on fracture mechanics theory. A novel parameter of \( \left| {\partial \cos \alpha /\partial \sum_{1} } \right| \) has been selected as the failure characteristic parameter for coal containing gas.

Mechanisms non-enzymatic browning in orange juice during storage
Food Chemistry, 2019The role of Reactive Carbonyl Species (RCS) derived from the Maillard reaction and ascorbic acid degradation on brown color formation was investigated in orange juice during storage. Eight RCS were monitored in aseptic juice over an 8-week period under refrigerated (4 °C) and accelerated conditions (35 °C).

Polyphenol Oxidase: Characteristics and Mechanisms of Browning Control
Food Reviews International, 2008Polyphenol oxidase, a copper-containing metalloprotein, catalyzes the oxidation of phenolic compounds to quinones, which produce brown pigments in wounded tissues. This enzymatic mechanism causes post harvest losses and mainly affects tropical fruits.

Mechanisms of stimulus-calorigenesis coupling in brown adipose tissue
Canadian Journal of Biochemistry and Cell Biology, 1984The sequence of metabolic events leading to increased calorigenesis in brown adipose tissue has been reviewed. The first step of this sequence consists in the binding of norepinephrine to adrenergic receptors of the beta1 subtype. This results in the stimulation of adenylate cyclase and activation of lipolysis via the system of protein kinases ...

Brown adipose tissue: the molecular mechanism of its formation
Nutrition Reviews, 2009The function of brown adipose tissue (BAT) is to oxidize fat and to dissipate the energy produced as heat, providing a source of heat to the organism. Preadipocytes are stimulated by expression of the PRDM16 gene to differentiate into BAT cells. The PRDM16 protein is greatly enriched in BAT and causes increased expression of mitochondrial genes and ...

Comparison of the mechanism of enzymatic browning in frozen white and brown A. bisporus
European Food Research and Technology, 2018The mechanism of browning in frozen white and brown A. bisporus stored for 8 months at − 25 °C has been determined based on the level of enzymatic activity, free amino acids, total polyphenols, antioxidant activity and color. The brown variety was less resistant than the white variety to enzymatic browning, due to a higher activity of monophenolase and
