Dark photon relic dark matter production through the dark axion portal [PDF]
, 2017 We present a new mechanism to produce the dark photon ($\gamma'$) in the early universe with a help of the axion ($a$) using a recently proposed dark axion portal. The dark photon, a light gauge boson in the dark sector, can be a relic dark matter if its

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome
Biological Reviews, EarlyView.ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Thyrotropin-Releasing Hormone and Food Intake in Mammals: An Update
MetabolitesThyrotropin-releasing hormone (TRH; pGlu-His-Pro-NH2) is an intercellular signal produced mainly by neurons. Among the multiple pharmacological effects of TRH, that on food intake is not well understood.

Characterization of a novel thyrotropin-releasing hormone receptor, TRHR3, in chickens
Poultry Science, 2020 The physiological roles of thyrotropin-releasing hormone (TRH) are proposed to be mediated by TRH receptors (TRHR), which have been divided into 3 subtypes, namely, TRHR1, TRHR2, and TRHR3, in vertebrates.

Interaction between the hypothalamo-pituitary-adrenal and thyroid axes during immobilization stress
Frontiers in Physiology, 2022 The location of corticotropin-releasing hormone receptor 2 (CRH-R2) on thyrotropes within the avian anterior pituitary (APit) and its activation by different stressors indicate a possible communication between hypothalamo-pituitary-adrenal (HPA) and ...

, 2008 We show that hidden-sector dark matter is a generic feature of the type IIB string theory landscape and that its lifetime may allow for a discovery through the observation of very energetic gamma-rays produced in the decay.

Developmental Dynamics, EarlyView.Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...

Tanycytes and the Control of Thyrotropin-Releasing Hormone Flux Into Portal Capillaries
Frontiers in Endocrinology, 2019 Central and peripheral mechanisms that modulate energy intake, partition and expenditure determine energy homeostasis. Thyroid hormones (TH) regulate energy expenditure through the control of basal metabolic rate and thermogenesis; they also modulate ...

Microbiology Spectrum, 2023 To better characterize the population dynamics of Vibrio parahaemolyticus (Vp) containing different virulence genes, two Vp strains were inoculated into seawater separately and incubated at temperatures (10°C and 30°C) mimicking winter and summer pre ...

Solitons of Sigma Model on Noncommutative Space as Solitons of Electron System
, 2005 We study the relationship of soliton solutions for electron system with those of the sigma model on the noncommutative space, working directly in the operator formalism.
