Evidence for efficient non-evaporative leaf-to-air heat dissipation in a pine forest under drought conditions.

New Phytol 2021 Sep 18. Epub 2021 Sep 18.

Earth & Planetary Sciences, Weizmann Institute of Science, 7610001, Rehovot, Israel.

Drier climates predicted for many regions result in reduced evaporative cooling leading to leaf heat stress and enhanced mortality. The extent to which non-evaporative cooling can contribute to plant resilience to the increasingly stressful conditions is poorly known at present. Using a novel, high accuracy infrared system for continuous measurements of leaf temperature in mature trees under field conditions, we assessed leaf-to-air temperature differences (ΔT ) of pine needles during drought.

Inactivation mode of sodium channels defines the different maximal firing rates of conventional versus atypical midbrain dopamine neurons.

PLoS Comput Biol 2021 Sep 17;17(9):e1009371. Epub 2021 Sep 17.

Department of Cell Biology and Anatomy, School of Medicine, Louisiana State University Health Sciences Center, New Orleans, Louisiana, United States of America.

Two subpopulations of midbrain dopamine (DA) neurons are known to have different dynamic firing ranges in vitro that correspond to distinct projection targets: the originally identified conventional DA neurons project to the dorsal striatum and the lateral shell of the nucleus accumbens, whereas an atypical DA population with higher maximum firing frequencies projects to prefrontal regions and other limbic regions including the medial shell of nucleus accumbens. Using a computational model, we show that previously identified differences in biophysical properties do not fully account for the larger dynamic range of the atypical population and predict that the major difference is that originally identified conventional cells have larger occupancy of voltage-gated sodium channels in a long-term inactivated state that recovers slowly; stronger sodium and potassium conductances during action potential firing are also predicted for the conventional compared to the atypical DA population. These differences in sodium channel gating imply that longer intervals between spikes are required in the conventional population for full recovery from long-term inactivation induced by the preceding spike, hence the lower maximum frequency.

Bidirectional relationships between intuitive eating and shape and weight overvaluation, dissatisfaction, preoccupation, and fear of weight gain: A prospective study.

Body Image 2021 Sep 13;39:227-231. Epub 2021 Sep 13.

School of Psychology, Deakin University, 1 Gheringhap Street, Geelong, VIC 3220, Australia.

Using a prospective design, we investigated possible bi-directional relationships between intuitive eating and four empirically distinct components of negative body image: overvaluation (judgements of self-worth contingent upon weight/shape), dissatisfaction (general discontent with weight/shape), preoccupation (ruminative thinking about weight/shape), and fear of weight gain. We assessed adult women at baseline (T1) and four-month follow-up (T2), as prior work has demonstrated that this time lag is sufficient to detect change in intuitive eating scores. After adjusting for T1 intuitive eating scores and demographic confounds, higher T1 dissatisfaction was the only body image component to significantly predict lower T2 intuitive eating scores in both univariate and multivariate models.
