Nat Commun. 2021 Jun 08;12(1):3432. doi: 10.1038/s41467-021-23528-8.

We present an efficient strategy to modulate tunnelling in molecular junctions by changing the tunnelling decay coefficient, β, by terminal-atom substitution which avoids altering the molecular backbone. By varying X = H, F, Cl, Br, I in junctions with...

Diagnostic Yield of a Systematic Vascular Health Screening Approach in Adolescents at Schools.

PURPOSE: A significant proportion of noncommunicable diseases in adults has its roots in adolescence, and this is particularly true for cardiovascular disease and stroke. Detection of vascular and metabolic risk factors at young ages may aid disease prevention.METHODS: In...

Collectively induced quantum-confined Stark effect in monolayers of molecules consisting of polar repeating units.

Journal of the American Chemical Society

Rissner F, Egger DA, Natan A, Körzdörfer T, Kümmel S, Kronik L, Zojer E.
PMID: 21955058
J Am Chem Soc. 2011 Nov 23;133(46):18634-45. doi: 10.1021/ja203579c. Epub 2011 Oct 27.

The electronic structure of terpyrimidinethiols is investigated by means of density-functional theory calculations for isolated molecules and monolayers. In the transition from molecule to self-assembled monolayer (SAM), we observe that the band gap is substantially reduced, frontier states increasingly...

Insulin signaling and osmotic stress response regulate arousal and developmental progression of C. elegans at hatching.

Genetics

Bayer EA, Liberatore KM, Schneider JR, Schlesinger E, He Z, Birnbaum S, Wightman B.

Genetics. 2021 Nov 12; doi: 10.1093/genetics/iyab202. Epub 2021 Nov 12.

The progression of animal development from embryonic to juvenile life depends on the coordination of organism-wide responses with environmental conditions. We found that two transcription factors that function in interneuron differentiation in Caenorhabditis elegans, fax-1 and unc-42, are required...

Global suicide rates have increased in recent decades becoming a serious social and public health problem. In Brazil, rates have been increasing annually. We aimed to analyze the correlation between suicide mortality rates and global economic and political crisis...

A Comparison of Dopaminergic and Cholinergic Populations Reveals Unique Contributions of VTA Dopamine Neurons to Short-Term Memory.

Cell reports

Choi JY, Jang HJ, Ornelas S, Fleming WT, Fürth D, Au J, Bandi A, Engel EA, Witten IB.
PMID: 33326775
Cell Rep. 2020 Dec 15;33(11):108492. doi: 10.1016/j.celrep.2020.108492.

We systematically compare the contributions of two dopaminergic and two cholinergic ascending populations to a spatial short-term memory task in rats. In ventral tegmental area dopamine (VTA-DA) and nucleus basalis cholinergic (NB-ChAT) populations, trial-by-trial fluctuations in activity during the...

The regulation of glucose-stimulated insulin secretion and glucose excursion has a sensory component that operates in a sex-dependent manner.OBJECTIVE: Here, we aim to dissect the basis of the sexually dimorphic interaction between sensory neurons and pancreatic β cells and...

A day of immersive physiology experiments increases knowledge and excitement towards physiology and scientific careers in Native American students.

Underserved minority groups are disproportionately absent from the pursuit of careers in science, technology, engineering, and mathematics (STEM) fields. One such underserved population, Native Americans, are particularly underrepresented in STEM fields. Although recent advocacy and outreach designed toward increasing...
