The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Loading-Rate Dependence of Rocks in Postfailure Region under Triaxial Compression

Advances in Materials Science and Engineering, 2018
To study the loading-rate dependence of four types of rocks in the peak and postfailure regions, the alternative strain rate test method is employed in conducting triaxial compressive tests under different confining pressure and moisture conditions.

Rate-Distortion Region of a Gray–Wyner Model with Side Information

Entropy, 2017
In this work, we establish a full single-letter characterization of the rate-distortion region of an instance of the Gray–Wyner model with side information at the decoders.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Associations of heart rates and respiratory rates with lifestyle and environmental factors in toddlers: a nationwide cohort study

BMC Pediatrics
Background Heart rate (HR) and respiratory rate (RR) are key vital signs, yet few large studies have reported their normal values in toddlers. We thus assessed HR and RR in two-year-old Japanese children.

Characteristics and influencing mechanisms of soil nitrous oxide (N2O) emissions from forestlands at different slope positions in karst regions

Carsologica Sinica
Greenhouse gases reflect long-wave infrared radiation from the Earth’s surface, causing the rise in global temperatures. Nitrous oxide (N2O) is one of the three major greenhouse gases, with a century-long warming potential 296 times greater than that of ...

Shelter and Nutrition Poverty of Children in Tehran in 2011 [PDF]

پژوهشهای اقتصادی, 2017
This study measures the children's poverty rate in Tehran (people under the age of 18) and identifies the most effective factors on children poverty in 2011. By using a sample of 24000 children under age of 18 extracted from "Tehran's Justice Measurement

Successive Refinement of Abstract Sources [PDF]

, 2018
In successive refinement of information, the decoder refines its representation of the source progressively as it receives more encoded bits. The rate-distortion region of successive refinement describes the minimum rates required to attain the target ...

Inter-regional variations in suicide rates.

Psychiatria Danubina, 2012
Suicidal behaviour is a significant public health problem. Suicide alone represents the 10th leading cause of death worldwide. Suicide is a complex phenomenon and may be the result of an interaction of biological, psychological and socioeconomic factors. Although there are many differences in suicide rates between different countries in the world, some

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
