Sixteen β-keto sulfide derivatives of carvacrol (4-19) incorporating phenyl or N, O and S heterocyclic moieties were synthesized in three steps. The relationships between heterocyclic structure and cupric, Cu(II), ion reducing antioxidant capacity (CUPRAC) were examined. Nine of the compounds (8-9 and 13-19) showed better CUPRAC activity than trolox at neutral pH, with trolox equivalent antioxidant capacity (TEAC) coefficients ranging between 1.20 and 1.75. Two derivatives (11-12) showed comp…

We present experimentally determined potential energy curves for the 10(0)[4Π] electronic state of NaCs. The 10(0)[4Π] state exhibits a double-minimum structure, resulting in a distinctive bound-free fluorescence signature. The perturbation facilitated optical-optical double resonance method was used to obtain Doppler-free excitation spectra corresponding to rovibrational transitions to the 10(0)[4Π] state. Spectroscopic constants were determined to summarize data belonging to inner well, out…

Binge drinking is an increasingly common pattern of risky use associated with numerous health problems, including alcohol use disorders. Because low basal plasma levels of β-endorphin (β-E) and an increased β-E response to alcohol are evident in genetically at-risk human populations, this peptide is thought to contribute to the susceptibility for disordered drinking. Animal models suggest that the effect of β-E on consumption may be sex-dependent. Here, we studied binge-like EtOH consumption …

Carvacrol (1) and thymol (2) were converted to their alkyl 4-oxobutanoate derivatives (7-20) in three steps, and evaluated for tyrosinase inhibitory activity. The compounds showed structure-dependent activity, with all alkyl 4-oxobutanoates, except 7 and 20, showing better inhibitory activity than the precursor 4-oxobutanoic acids (5 and 6). In general, thymol derivatives exhibited a higher percent inhibitory activity than carvacrol derivatives at 500 μM. Derivatives containing three-carbon a…

Small bacterial and archaeal genomes provide insights into the minimal requirements for life and are phylogenetically widespread. However, the precise environmental pressures that constrain genome size in free-living microorganisms are unknown. A study including isolates has shown that thermophiles and other bacteria with high optimum growth temperatures often have small genomes. It is unclear whether this relationship extends generally to microorganisms in nature and more specifically to mic…

This paper asks how do the deaths and the postmortem detransitioning (the verbal, visual, and material rejection of a person's gender identity) of transgender women impact trans activism? After analyzing the case studies of Jennifer Gable and Leelah Alcorn, I outline how the contentious memorialization of transgender women and the disenfranchized grief of survivors influence trans activism. I conclude that activism is characterized by respecting the wishes of the deceased, by preventing the v…

The ETS family of transcription factors are evolutionarily conserved throughout the metazoan lineage and are critical for regulating cellular processes such as proliferation, differentiation, apoptosis, angiogenesis, and migration. All members have an ETS DNA binding domain, while a subset also has a protein-protein interaction domain called the SAM domain. Pointed (Pnt), an ETS transcriptional activator functions downstream of the receptor tyrosine kinase (RTK) signaling pathway to regulate …

This work aims to fully elucidate the effects of a trehalose glassy matrix on electron transfer reactions in cyanobacterial Photosystem I (PS I). Forward and backward electron transfer rates from A and A to F and charge recombination rates from A, A, A, F, and [F/F] to P were measured in P-F/F complexes, P-F cores, and P-A cores, both in liquid and in a trehalose glassy matrix at 11% humidity. By comparing CONTIN-resolved kinetic events over 6 orders of time in increasingly simplified version…

Experimental auctions allow researchers to estimate demand for products like e-cigarettes in a non-hypothetical environment where participants face real and immediate consequences for their bids. However, because auction winners actually purchase the product they bid on, participants may be introduced to a product they otherwise would not have discovered. Based on an experimental auction where 432 participants bid to buy e-cigarettes, we found that auction winners are significantly more likel…

One key aspect of cell division in multicellular organisms is the orientation of the division plane. Proper division plane establishment contributes to normal plant body organization. To determine the importance of cell geometry in division plane orientation, we designed a three-dimensional probabilistic mathematical model to directly test the century-old hypothesis that cell divisions mimic soap-film minima. According to this hypothesis, daughter cells have equal volume and the division plan…
