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 ...

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.

Research Progress in the Browning Mechanism of Apple Juice and Their Color Protection Mechanism by Antioxidants

Shipin gongye ke-ji, 2022
As the main processing product of apple in China, juice contributed great to the value-added of the industry. However, browning reaction is easy to occur during processing and storage, resulting in color instability, quality deterioration and reduced ...

Integration of Metabolome and Transcriptome Profiling Reveals the Effect of Modified Atmosphere Packaging (MAP) on the Browning of Fresh-Cut Lanzhou Lily (Lilium davidii var. unicolor) Bulbs during Storage

Foods, 2023
The fresh-cut bulbs of the Lanzhou lily (Lilium davidii var. unicolor) experience browning problems during storage. To solve the problem of browning in the preservation of Lanzhou lily bulbs, we first investigated the optimal storage temperature and gas ...

PexRAP inhibits PRDM16-mediated thermogenic gene expression [PDF]

, 2017
How the nuclear receptor PPARγ regulates the development of two functionally distinct types of adipose tissue, brown and white fat, as well as the browning of white fat, remains unclear.

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.

Natural Extracts That Stimulate Adipocyte Browning and Their Underlying Mechanisms [PDF]

Antioxidants, 2021
Despite progress in understanding the developmental lineage and transcriptional factors regulating brown and beige adipocytes, the role of environmental modifiers, such as food components and natural extracts, remains to be elucidated. Furthermore, the undesirable pleiotropic effects produced by synthetic drugs targeting adipose tissue browning and ...

Sulforaphane induces adipocyte browning and promotes glucose and lipid utilization [PDF]

, 2016
Scope: Obesity is closely related to the imbalance of white adipose tissue storing excess calories, and brown adipose tissue dissipating energy to produce heat in mammals.
