HOMAc: A Parameterization of the Harmonic Oscillator Model of Aromaticity (HOMA) That Includes Antiaromaticity.
J Org Chem
January 2025
Division of Theoretical Chemistry, IFM, Linköping University, 58183 Linköping, Sweden.
The harmonic oscillator model of aromaticity (HOMA) offers a straightforward route to quantifying aromaticity that requires no other information than the bond lengths of the conjugated ring in question. Given that such information is often readily obtainable from quantum-chemical calculations, it is pertinent to improve this parametrized model as much as possible. Here, a new version of HOMA is presented where, atypically, the corresponding parameters are derived from the actual bond lengths of both aromatic and antiaromatic (rather than nonaromatic) reference compounds, as calculated with a high-level method.

Recognizing and diagnosing lymphoma in patients with fever of unknown origin (FUO) can be challenging, and misdiagnosis is not uncommon. To improve understanding of the clinical characteristics of lymphoma patients presenting with FUO who were misdiagnosed with autoimmune diseases. A retrospective, observational study of 140 consecutive patients with FUO and lymphoma presenting to a tertiary center between January 2017 and December 2023.

J Nutr Educ Behav
January 2025
Economic Research Service, US Department of Agriculture.
Objective: Describe experiences of, and responses to, 2022 infant formula shortages among households with infants aged up to 18 months by race/ethnicity using Household Pulse Survey data.
Methods: Outcomes included whether households were affected by shortages and, if so, 3 nonmutually exclusive response categories (increased breastmilk, obtained formula atypically, and disruptive coping [disruptions to breastmilk and/or formula]) and 1 mutually exclusive response category (solely disruptive coping). Unadjusted shares reporting each were compared using t tests.
Temporal Lobe Epilepsy Perturbs the Brain-Wide Excitation-Inhibition Balance: Associations with Microcircuit Organization, Clinical Parameters, and Cognitive Dysfunction.

McConnell Brain Imaging Centre, Montreal Neurological Institute and Hospital, McGill University, Montreal, QC, H3A 2B4, Canada.
Excitation-inhibition (E/I) imbalance is theorized as a key mechanism in the pathophysiology of epilepsy, with ample research focusing on elucidating its cellular manifestations. However, few studies investigate E/I imbalance at the macroscale, whole-brain level, and its microcircuit-level mechanisms and clinical significance remain incompletely understood. Here, the Hurst exponent, an index of the E/I ratio, is computed from resting-state fMRI time series, and microcircuit parameters are simulated using biophysical models.
