Brain magnetic resonance imaging predictors in anti‐N‐methyl‐D‐aspartate receptor encephalitis
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1974-1984, December 2022., 2022 Abstract Objective Brain magnetic resonance imaging (MRI) findings in anti‐N‐methyl‐D‐aspartate receptor (NMDAR) encephalitis are nonspecific and rarely have obvious associations with clinical characteristics and outcomes. This study aimed to comprehensively describe the MRI features of patients with NMDAR encephalitis, examine their associations with ...

Seed dormancy in ornamental plants: A review
The Indian Journal of Agricultural Sciences, 2016 Seed is the first input used in transfer of genetic traits in ornamental plants production. Seed dormancy is a physiological phenomenon in plants, which is caused by external or internal factors, and prevents seed germination, even in optimal conditions.

Seed dormancy and the control of germination.
New Phytologist, 2006 Seed dormancy is an innate seed property that defines the environmental conditions in which the seed is able to germinate. It is determined by genetics with a substantial environmental influence which is mediated, at least in part, by the plant hormones ...

Frontiers in Plant Science, 2015 Seed dormancy controls germination and plays a critical role in regulating the beginning of the life cycle of plants. Seed dormancy is established and maintained during seed maturation and is gradually broken during dry storage (after-ripening).

The American Naturalist, 2018 Although metacommunity ecology has improved our understanding of how dispersal affects community structure and dynamics across spatial scales, it has yet to adequately account for dormancy. Dormancy is a reversible state of reduced metabolic activity that enables temporal dispersal within the metacommunity.

Diverse reactions catalyzed by cytochrome P450 and biosynthesis of steroid hormone
Biophysics and Physicobiology, 2022 Steroid hormones modulate numerous physiological processes in various higher organisms. Research on the physiology, biosynthesis, and metabolic degradation of steroid hormones is crucial for developing drugs, agrochemicals, and anthelmintics.

A Cellular Automaton Model for Tumor Dormancy: Emergence of a Proliferative Switch [PDF]
Chen D, Jiao Y, Torquato S (2014) A Cellular Automaton Model for
Tumor Dormancy: Emergence of a Proliferative Switch. PLoS ONE 9(10): e109934, 2014 Malignant cancers that lead to fatal outcomes for patients may remain dormant for very long periods of time. Although individual mechanisms such as cellular dormancy, angiogenic dormancy and immunosurveillance have been proposed, a comprehensive understanding of cancer dormancy and the "switch" from a dormant to a proliferative state still needs to be ...

Frontiers in Plant Science, 2016 Dormancy inhibits seed and bud growth of perennial plants until the environmental conditions are optimal for survival. Previous studies indicated that certain co-regulation pathways exist in seed and bud dormancy. In our study, we found that seed and bud

Models of Microbial Dormancy in Biofilms and Planktonic Cultures [PDF]
Commun. Math. Sci., 10(2) pp. 493-511, 2012, 2010 We present models of dormancy in a planktonic culture and in biofilm, and examine the relative advantage of short dormancy versus long dormancy times in each case. Simulations and analyses indicate that in planktonic batch cultures and in chemostats, live biomass is maximized by the fastest possible exit from dormancy.
