On Detecting Biospheres from Chemical Thermodynamic Disequilibrium in Planetary Atmospheres. [PDF]

Astrobiology, 2015
Atmospheric chemical disequilibrium has been proposed as a method for detecting extraterrestrial biospheres from exoplanet observations. Chemical disequilibrium is potentially a generalized biosignature since it makes no assumptions about particular ...

Leptin Aggravates Thoracic Aortic Dissection Through Impairment of Energy Metabolism in Nrip2+ Smooth Muscle Cells

Advanced Science, EarlyView.
Epidemiological data confirm obesity elevates thoracic aortic dissection (TAD) risk. Patient analyses implicate hyperleptinemia, where leptin binding to vascular smooth muscle cell (VSMC) receptors triggers Socs3‐mediated suppression of Stat5a transcriptional activity.

Rényi’s Entropy, Statistical Order and van der Waals Gas

Entropy, 2022
The notion of statistical order derives from the disequilibrium concept introduced by López-Ruiz, Mancini, and Calbet thirty years ago. In this effort, it is shown that the disequilibrium is intimately linked to the celebrated Rényi entropy.

Ataxia and Disequilibrium

Practica Oto-Rhino-Laryngologica, 1981
Ataxia and disequilibrium are clinical symptoms expressing basic conditions of body balance. The author proposed to give them clear definitions concerning the human posture. Ataxia would mean the failure in maintaining the posture during more complicated movement, while disequilibrium implys the disturbed body balance in static posture while standing ...

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa

Advanced Science, EarlyView.
Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

Linkage disequilibrium in humans: models and data.

American Journal of Human Genetics, 2001
In this review, we describe recent empirical and theoretical work on the extent of linkage disequilibrium (LD) in the human genome, comparing the predictions of simple population-genetic models to available data.

A Blast‐Resistant NLR Gene Confers Drought Resistance by Competitively Interacting with an E3 Ligase to Protect Phenylalanine Ammonia‐Lyase in Rice

Advanced Science, EarlyView.
The NLR protein PibH8 interacts with phenylalanine ammonia‐lyase OsPAL1 and E3 ubiquitin ligase OsFBK16. Through competitive binding, PibH8 weakens the interaction between OsFBK16 and OsPAL1, thereby reducing the degradation of OsPAL1 by OsFBK16. The Hap1 allele of PibH8 exhibits a higher expression level than Hap2, thus accumulating more PibH8 protein,

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle

Advanced Science, EarlyView.
This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in

Co‐Selection of Low Cadmium Accumulation and High Yield During Tomato Improvement

Advanced Science, EarlyView.
This study finds that large‐fruited tomatoes accumulate less cadmium (Cd) compared to wild tomatoes and cherry tomatoes. This is because, during the improvement process of tomato, the low‐Cd allele LCT1A and the large fruit allele fw3.2T are closely linked, leading to a co‐selection event.
