Novel Browning Agents, Mechanisms, and Therapeutic Potentials of Brown Adipose Tissue [PDF]
BioMed Research International, 2016 Nonshivering thermogenesis is the process of biological heat production in mammals and is primarily mediated by brown adipose tissue (BAT). Through ubiquitous expression of uncoupling protein 1 (Ucp1) on the mitochondrial inner membrane, BAT displays uncoupling of fuel combustion and ATP production in order to dissipate energy as heat.

The formation mechanism of brown dwarfs [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 We present results from the first hydrodynamical star formation calculation to demonstrate that brown dwarfs are a natural and frequent product of the collapse and fragmentation of a turbulent molecular cloud. The brown dwarfs form via the fragmentation of dense molecular gas in unstable multiple systems and are ejected from the dense gas before they ...

Mechanisms associated with the depigmentation of brown eggshells: a review
Poultry Science, 2021 Eggshell color is an important shell quality trait that influences consumer preference. It is also of particular importance with respect to sexual signaling and the physiological and mechanical properties of shell pigment. Pigments include protoporphyrin IX, biliverdin, and traces of biliverdin zinc chelates, with brown eggs being notably rich in ...

The photoprotection mechanism in the black–brown pigment eumelanin
Proceedings of the National Academy of Sciences, 2022 The natural black–brown pigment eumelanin protects humans from high-energy UV photons by absorbing and rapidly dissipating their energy before proteins and DNA are damaged. The extremely weak fluorescence of eumelanin points toward nonradiative relaxation on the timescale of picoseconds or shorter.

Multi-Omics Landscape of DNA Methylation Regulates Browning in “Fuji” Apple
Frontiers in Nutrition, 2022 Browning seriously affects the quality of fresh-cut fruits, and its mechanism was thought to be polyphenol oxidase (PPO) in the past. A way of non-different PPO browning was found in our previous studies.

The Mechanism of White and Brown Adipocyte Differentiation [PDF]
Diabetes & Metabolism Journal, 2013 Obesity gives vent to many diseases such as type 2 diabetes, hypertension, and hyperlipidemia, being considered as the main causes of mortality and morbidity worldwide. The pathogenesis and pathophysiology of metabolic syndrome can well be understood by studying the molecular mechanisms that control the development and function of adipose tissue.

Browning mechanism and process optimization during MaizeMaize KX7349 Drying
Julius-Kühn-Archiv, 2018 Browning of KX7349 maize during drying occurred mainly in the pericarp layer. Browning was caused by oxidation of water soluble matter in the pericarp layer. Moisture content had no significant influence on browning rate.
