The thermogenic activity of brown adipose tissue (BAT) and browning of white adipose tissue are important components of energy expenditure. Here we show that GPR120, a receptor for polyunsaturated fatty acids, promotes brown fat activation. Using RNA-seq to analyse mouse BAT transcriptome, we find that the gene encoding GPR120 is induced by thermogenic activation. We further show that GPR120 ac...

Chilling damage under 15ºC in anthurium cut flowers reduces the vase-life, quality and marketability of the product. In the present experiment, GABA postharvest treatment (0, 1 and 5 mM) was studied on the vase-life, total soluble solid (TSS), H2O2 content, proline content, spathe browning, catalase and superoxide dismutase enzymes activity of Anthurium andraeanum...

background: embryonic stem cells (esc) are pluripotent cells which have been used as a model to study the mechanism that control the embryogenesis and early mammalian development in vitro. the aim of this study was to isolate and produce embryonic stem cells from late blastocyst stage embryos in mice. materials and methods: blastocyst stage embryos from pregnant nmri mice were obtained and cult...

microwave assisted fluidized bed drying is a novel drying technique which reduces drying time and yields higher quality products. in this study the effect of this method on color changes of whole and cut hazelnut kernels was investigated. the parameters of color and resulting total color change, chroma, hue angle and browning index were also calculated during drying in three temperatures (40, 5...

Brown adipose tissue (BAT) may have untapped therapeutic potential for treating metabolic disorders including type 2 diabetes and obesity because it not only dissipates energy through the expression of uncoupling protein 1 (Ucp1), but it also plays a role in diet and nonshivering thermogenesis. BAT can emerge from white fat in a process called “browning,” but how this process occurs has remaine...

CONTEXT Obesity is associated with a low-grade inflammatory state and adipocyte (ADP) hyperplasia/hypertrophy. Obesity inhibits the "browning" of white adipose tissue. Cannabinoid receptor 2 (CB2) agonists reduce food intake and induce antiobesity effect in mice. A common missense CB2 variant, Q63R, causes CB2-reduced function. OBJECTIVE To evaluate the influence of CB2 receptor on the modula...

Alternate strategies for prevention of enzymatic browning of fruits and vegetables are required by food industries due to restrictions and several negative health attributes of sulphites, which are effective inhibitors of enzymatic browning reaction. These reactions result mostly from polyphenol oxidase (PPO). The present study was conducted to evaluate the antioxidant and PPO inhibitory potent...

The effect of different anti-browning agents on partially purified longan polyphenol oxidase (PPO) activity was investigated by spectrophotometry, using catechol as a phenolic substrate. For this purpose, L-cysteine, potassium metabisulfite, ascorbic acid, and citric acid were used to inhibit the activity of longan PPO at different concentrations (0-10 mM). Lcysteine was found to be the most po...

in this research the effect of conventional and ohmic pasteurization and storage time at different temperatures on some bioactive components of aloe vera gel juice was investigated. aloe vera gel juice was pasteurized conventionally and ohmically at 90 ºc for 1 min. the effect of pasteurization on vitamin c, total phenolic content  and juice color was evaluated. the samples pasteurized conventi...
