Estrogen, via estrogen receptor alpha (ERα), exerts several beneficial effects on metabolism and energy homeostasis by controlling size, enzymatic activity and hormonal content of adipose tissue. The actions of estrogen on sympathetic ganglia, which are key players in the browning process, are less well known. In the present study we show that ERβ influences browning of subcutaneous adipose tis...

Abstract Deastringency treatment with CO 2 is an effective and convenient method for improving the marketability of persimmon fruit. However, main cultivars in China turn brown very quickly following exposure to a high-CO atmosphere, causing significant economic loss. mechanisms browning under remain largely unknown. In this study, we evaluated components enzymes related fruit browning. The res...

Polyphenol oxidases (PPO) are enzymes that catalyze the browning of fruits and vegetables when oxygen in air reacts with present phenolic compounds. This study demonstrates enzymatic food samples inhibition its activity by common household materials. Fresh were tested different treatments acidic ionic solutions, syrups. Observations from students’ work showed changes pH, surface area for site r...

BACKGROUND Pericarp browning is a critical problem resulting in reduced commercial value and shelf life of longan fruit. RESULTS Two non-protein amino acids, α-aminoisobutyric acid (AIB) and β-aminoisobutyric acid (BAIB) at 100 and 1 mM were applied to longan fruit prior to storage for up to 8 days at 25 °C respectively. Contents of the major five phenolics (gallic acid, catechin, corilagin, ...

Received: December 28, 2013; Revised; January 25, 2014; Accepted: March 2, 2014 . Abstract: A major problem in the micro propagation of litchi is the secretion of polyphenols into the medium by the tissues once excised. This secretion undergoes oxidation to produce substances that kill the tissues. The first visual symptom of deterioration is skin browning which has been reported to appear due ...

There are two distinct types of adipose tissue which have different functions within the body, white (WAT) and brown (BAT). Browning of WAT occurs with increases in the WAT sympathetic nervous system (SNS) drive. In this regard we previously reported that melatonin (MEL) stimulation of MEL receptor 1A (MEL1a) within the SNS outflow to the WAT might be implicated in a naturally-occurring reversa...

Fuji apples may develop the physiological disorders core flush or flesh browning during cold storage in air (RA) or controlled atmosphere (CA) (Argenta et al., 2000). Core flush is a symptom of senescence characterized by yellow-brown discoloration in the core (Wilkinson and Fidler, 1973). In Fuji apples, flesh browning (Photo 1) resembles senescent breakdown because the diffuse, light brown di...
