Cholesterol 7α-hydroxylase (CYP7A1) encodes for the rate-limiting step in conversion of cholesterol to bile acids liver. In response acute feeding, mice upregulate CYP7A1 via stimulation liver X receptor (LXR) α. However, effect a chronic high-cholesterol diet on hepatic expression is unknown. We demonstrate that feeding (0.2% or 1.25% w/w 12 weeks) FVB/NJ results >60% suppression associated with >2-fold increase content. contrast, induces >3-fold upregulation expression. show chronic, but...

Although substantial attention has focused on efforts by the new Administration to block environmental policies, climate politics have been contentious in US since well before election of Donald Trump. In this paper, we extend previous work empirical examinations echo chambers using data collected federal policy network summer 2016.

Endoplasmic reticulum (ER) stress has been implicated in the pathogenesis of nonalcoholic steatohepatitis. The ER response is activated livers mice fed a methionine- and choline-deficient (MCD) diet, yet role MCD diet-induced steatohepatitis unknown. Using chemical chaperones on hepatic steatosis markers inflammation fibrosis we aim to determine effects reducing stress. C57BL/6J were diet with or without 4-phenylbutyric acid (PBA) tauroursodeoxycholic (TUDCA) for 2 wk. TUDCA PBA effectively...

Existing research shows that childhood processes affect identity formation. However, there is limited scholarly understanding about how these work as children age. The case of environmental behavior offers the opportunity to interrogate processes. I use reflective interviews with 40 participants in 2014 People’s Climate March New York understand socialization shapes their perceptions formation related participation movement. argue movement facilitated by development compatible standards...

In this paper, I apply concepts from personal identity theory to understand how individuals perceive their standards related participation in the environmental movement. Using interview data collected 40 participants People’s Climate March, discuss contents of participants’ “environmental movement identities” and find a diversity normative expectations incorporated into standards, behavioral tied an identity. The varied self-concepts found these indicate heterogeneity people identities that...
