Capacity for increased surface area in the hydrophobic core of β-sheet peptide bilayer nanoribbons.

J Pept Sci 2021 Jun 20:e3334. Epub 2021 Jun 20.

Department of Chemistry, University of Rochester, Rochester, New York, USA.

Amphipathic peptides with amino acids arranged in alternating patterns of hydrophobic and hydrophilic residues efficiently self-assemble into β-sheet bilayer nanoribbons. Hydrophobic side chain functionality is effectively buried in the interior of the putative bilayer of these nanoribbons. This study investigates consequences on self-assembly of increasing the surface area of aromatic side chain groups that reside in the hydrophobic core of nanoribbons derived from Ac-(XKXE) -NH peptides (X = hydrophobic residue).

A Web-Based Positive Psychological Intervention to Improve Blood Pressure Control in Spanish-Speaking Hispanic/Latino Adults With Uncontrolled Hypertension: Protocol and Design for the ¡Alégrate! Randomized Controlled Trial.

JMIR Res Protoc 2020 Aug 4;9(8):e17721. Epub 2020 Aug 4.

Department of Medical Social Sciences, Northwestern University Feinberg School of Medicine, Chicago, IL, United States.

Background: Growing evidence links psychological well-being and resilience with superior cardiac health, but there remains a critical scientific gap about whether (or how) interventions that aim to cultivate psychological well-being reduce cardiac risk. Hispanic/Latino people in the United States have high cardiovascular disease risk and poorly controlled blood pressure (BP) compared with their peers of European ancestry, and they represent a population in need of new and innovative therapeutic approaches. As such, a focused intervention to boost psychological well-being holds promise as a novel therapeutic target for hypertension in Hispanic/Latino adults; to date, however, no research has explored whether a causal link is evident.

¡Viva la mitochondria!: harnessing yeast mitochondria for chemical production.

FEMS Yeast Res 2020 09;20(6)

Department of Molecular Biology, Princeton University, Princeton, NJ 08544, USA.

The mitochondria, often referred to as the powerhouse of the cell, offer a unique physicochemical environment enriched with a distinct set of enzymes, metabolites and cofactors ready to be exploited for metabolic engineering. In this review, we discuss how the mitochondrion has been engineered in the traditional sense of metabolic engineering or completely bypassed for chemical production. We then describe the more recent approach of harnessing the mitochondria to compartmentalize engineered metabolic pathways, including for the production of alcohols, terpenoids, sterols, organic acids and other valuable products.
