TL;DR: Neither MCF-7 nor T47D breast cancer cells were affected by BHB during glucose deprivation; however, screening of tumors for activation of ketone body-metabolizing enzymes may be able to identify patients that will benefit from ketogenic diet interventions.
Abstract: Ketogenic diets have the potential to lower glucose availability to cancer cells. However, the effect that the resulting increase in ketone bodies has on cancer cells is not fully understood. The present study explored the effect of β-hydroxybutyrate (BHB) on glucose-deprived MCF-7 and T47D breast cancer cells. Cell proliferation was decreased in response to lower glucose conditions, which could not be rescued consistently by 10 or 25 mM BHB supplementation. In addition, gene expression levels were altered when cells were glucose deprived. Reducing glucose availability of cancer cells to 225 mg/l for 4 days significantly decreased the expression of 113 genes and increased the expression of 100 genes in MCF-7 breast cancer cells, and significantly decreased the expression of 425 genes and increased the expression of 447 genes in T47D breast cancer cells. Pathway enrichment analysis demonstrated that glucose deprivation decreased activity of the Hippo-Yap cell signaling pathway in MCF-7 breast cancer cells, whereas it increased the expression of genes in the NRF2-pathaway and genes regulating ferroptosis in T47D breast cancer cells. Treatment of glucose-deprived cells with 10 or 25 mM BHB significantly changed the expression of 14 genes in MCF-7 breast cancer cells and 40 genes in T47D breast cancer cells. No significant pathway enrichment was detected when glucose-deprived cells were treated with BHB. Both cell lines expressed the enzymes (OXCT1/2, BDH1 and ACAT1/2) responsible for metabolizing BHB to acetyl-CoA, yet expression of these enzymes was not altered by either glucose deprivation or BHB treatment. In the publicly available The Cancer Genome Atlas (TCGA), increased expression of ketone body-catabolizing enzymes was observed in various types of cancer based on mRNA expression z-scores. Increased expression of BDH1 and ACAT1 significantly decreased overall survival of patients with breast cancer in TCGA studies, while decreased OXCT1 expression non-significantly decreased overall survival. In conclusion, neither MCF-7 nor T47D breast cancer cells were affected by BHB during glucose deprivation; however, screening of tumors for activation of ketone body-metabolizing enzymes may be able to identify patients that will benefit from ketogenic diet interventions.

TL;DR: A four-tiered approach to promote later school start times for middle and high schools is proposed, resulting in improvements in physical health, psychological well-being, attention and concentration, academic performance, and driving safety.
Abstract: The Society of Behavioral Medicine recommends school officials start middle and high school classes at 8:30 am or later. Such a schedule promotes students' sleep health, resulting in improvements in physical health, psychological well-being, attention and concentration, academic performance, and driving safety. In this position statement, we propose a four-tiered approach to promote later school start times for middle and high schools.

TL;DR: The C-terminal tail of Arc has a random coil (disordered) structure, and the tail starts from the residue D357, and NMR spectra showed that the C-Terminal tail has minimum (if any) interaction with its neighboring capsid domain in Arc.
Abstract: The activity-regulated cytoskeleton-associate protein Arc (or Arg3.1) is specifically linked to memory formation and a number of cognitive disorders, including Alzheimer's disease and schizophrenia. Since the discovery of Arc in 1995, extensive research has been conducted on the protein to identify its function and mechanisms of action, with solving the structure of Arc as a major goal. However, the Arc protein tends to self-oligomerize in vitro, and is difficult to crystallize. These properties have hindered efforts to obtain the structure of the full-length, whole protein Arc. As an alternative approach, we and others, have sought to solve the structures of various subdomain proteins of Arc, including the N-lobe, C-lobe, and capsid domain (N-lobe + C-lobe). In this study, we characterized the C-terminal tail of Arc using integrated bioinformatic and structural biology techniques. We compared the sequences of Arc proteins in different mammal species and found that the amino-acid composition in the C-terminal tail region has a significantly higher degree of variation rate than the rest of the protein. Structural prediction programs suggested that the C-terminal tail is structurally disordered. Chemical shift analysis based on solution NMR spectra confirmed that the C-terminal tail has a random coil (disordered) structure, and the tail starts from the residue D357. Furthermore, the NMR spectra showed that the C-terminal tail has minimum (if any) interaction with its neighboring capsid domain in Arc. This study fills gaps in our specific understanding of the structural nature and functional contributions of the Arc C-terminus.

TL;DR: It is suggested that mast cell release of key lipid mediators is altered in patients with metabolic syndrome, because of the impact on both the pro-inflammation and pro-resolution bioactive lipids that are released during mast cell activation.
Abstract: Mast cell lipid bodies are key to initiation, maintenance and resolution of inflammatory responses in tissue. Mast cell lines, primary bone marrow-derived mast cells and peripheral blood ba...

TL;DR: In this article, the authors present a study that reviewed recidivism outcomes for adult men and women imprisoned in two Hawai'i state prisons who participated in restorative justice re-entry circles prior to release.
Abstract: This chapter is based on a study that reviewed recidivism outcomes for adult men and women imprisoned in two Hawai‘i state prisons who participated in restorative justice re-entry circles prior to release. These men and women were tracked for at least three years after their release. Self-selection bias by choosing to have a circle was reduced by comparing recidivism outcomes of individuals who applied for and had a re-entry circle with those who applied for a circle, but did not have one. The chapter aims to contribute to the Handbook’s key objectives by presenting original research showing promising results with significantly lower recidivism for the 58 individuals in the experimental group that had circles compared to the 60 individuals in the control group who applied for a circle but did not have one.
