The role of microbiota in the regulation of homeostasis in the human body during infection

open access: yesЖурнал микробиологии, эпидемиологии и иммунобиологии, 2020
The review considers the regulatory capabilities of the human microbiota to preserve human health. The problem is not new, but it has expanded with the inclusion of new “findings” since the time of I.I.

A role for dopamine in control of the hypoxic ventilatory response via D2 receptors in the zebrafish gill

open access: yesJournal of Comparative Neurology, Volume 532, Issue 2, February 2024.
Dopamine is a neurotransmitter involved in oxygen sensing and control of reflex hyperventilation, but its role in respiratory control in aquatic vertebrates has been elusive. We present evidence for the synthesis and uptake of dopamine by postsynaptic sensory nerves, and the oxygen‐dependent expression of D2‐type dopamine receptors in respiratory ...

Suggestive role of eye-stalk of Macrobrachium gangeticum Bate, 1868 in regulation of its reproductive behaviour [PDF]

open access: yes, 2009
Role of eye-stalk of Macrobrachium gangeticum Bate, 1868 in its reproductive behaviour has been examined by conducting deletion and addition experiments.

«The Brain as a Whole» Concept: Facilitating Approaches to Brain Death Understanding

open access: yesОбщая реаниматология
James Bernat claimed that «the formulation of whole-brain death provides the most congruent map for our correct understanding of death». However, the author has recently proposed the categorization of another phrase: «brain as a whole (BAAW)».

Gliotransmission by Prostaglandin E2: a prerequisite for GnRH neuronal function?

open access: yesFrontiers in Endocrinology, 2011
Over the past four decades it has become clear that prostaglandin E2 (PGE2), a phospholipid-derived signaling molecule, plays a fundamental role in modulating the GnRH neuroendocrine system and in shaping the hypothalamus.

Regulation of ovigericity in a fresh water prawn macrobrachium lanchesteri (de Man) [PDF]

open access: yes, 1985
Summary The intermoult duration of ovigerous Macrobrachium lanchesteri, between the pre-spawning and the post-parturial moults, is significantly long, twice that of the adult non-ovigerous females.

Differential Maturation of the Two Regulated Secretory Pathways in Human iPSC-Derived Neurons

open access: yesStem Cell Reports, 2017
Neurons communicate by regulated secretion of chemical signals from synaptic vesicles (SVs) and dense-core vesicles (DCVs). Here, we investigated the maturation of these two secretory pathways in micro-networks of human iPSC-derived neurons.

Structural diversity of neuronal calcium sensor proteins and insights for activation of retinal guanylyl cyclase by GCAP1. [PDF]

open access: yes, 2014
Neuronal calcium sensor (NCS) proteins, a sub-branch of the calmodulin superfamily, are expressed in the brain and retina where they transduce calcium signals and are genetically linked to degenerative diseases.

Estrogen-Astrocyte interactions: Implications for neuroprotection

open access: yesBMC Neuroscience, 2002
Background Recent work has suggested that the ovarian steroid 17β-estradiol, at physiological concentrations, may exert protective effects in neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease and acute ischemic stroke.
