Chronic exposure to perfluorooctane sulfonate induces behavior defects and neurotoxicity through oxidative damages, in vivo and in vitro. [PDF]

open access: yesPLoS ONE, 2014
Perfluorooctane sulfonate (PFOS) is an emerging persistent pollutant which shows multiple adverse health effects. However, the neurotoxicity of PFOS and its mechanisms have not been fully elucidated.

Innovations in Obesity Treatment: Beyond Adipose Tissue Dysfunction

open access: yesObesity Reviews, EarlyView.
Obesity drives chronic inflammation, insulin resistance, type 2 diabetes, and cancer development through adipocyte dysfunction. Addressing this multisystemic disorder requires integrated strategies beyond diet and exercise, such as thermogenesis activation via menthol or capsinoids and appetite control through GLP‐1/GIP agonists and neuromodulation to ...

Asymmetric polar localization dynamics of the serine chemoreceptor protein Tsr in Escherichia coli. [PDF]

open access: yesPLoS ONE, 2018
The spatial location of proteins in living cells can be critical for their function. For example, the E. coli chemotaxis machinery is localized to the cell poles.

All Is Relative—A Call for Considering “Physiologically Informed” Control Conditions to Improve the Mechanistic Understanding of the Effects of Physical Exercise on Cognition

open access: yesScandinavian Journal of Psychology, EarlyView.
ABSTRACT There is a growing interest in elucidating the mechanisms that drive the benefits of physical exercise on cognitive performance. A key element for a better understanding of a particular phenomenon (e.g., the mediators of the exercise‐cognition interaction) is the selection of an appropriate control condition/group as the basis for causal ...

A pH‐sensitive chloride current in the chemoreceptor cell of rat carotid body [PDF]

open access: yesThe Journal of Physiology, 2001
1. Cardiorespiratory response to acidosis is initiated by the carotid body. 2. The direct effect of extracellular pH (pH(o)) on the chloride currents of isolated chemoreceptor cells of the rat carotid body was investigated using the whole-cell patch-clamp technique. 3. On applying intra- and extracellular solutions with a symmetrical high-Cl(-) content

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

open access: yesExperimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Sensitive and Selective in Vitro Recognition of Biologically Toxic As(III) by Rhodamine Based Chemoreceptor

open access: yes, 2019
Arsenic induced cleavage of the spirolactam ring of a cleft shaped electronically enriched rhodamine based chemoreceptor molecule 3′,6′-bis­(ethylamino)-2-((2-hydroxy-5-methylbenzylidene)­amino)-2′,7′-dimethylspiro­[isoindoline-1,9′-xanthen]-3-one ...

Time‐course analysis of cerebral circulation and cardiorespiratory responses to acute central blood volume reduction in healthy young males

open access: yesExperimental Physiology, EarlyView.
Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

Cryo-Electron Tomography Reveals the Complex Ultrastructural Organization of Multicellular Filamentous Chloroflexota (Chloroflexi) Bacteria

open access: yesFrontiers in Microbiology, 2020
The cell biology of Chloroflexota is poorly studied. We applied cryo-focused ion beam milling and cryo-electron tomography to study the ultrastructural organization of thermophilic Roseiflexus castenholzii and Chloroflexus aggregans, and mesophilic “Ca ...

In Vivo Crosslinking Methods for Analyzing the Assembly and Architecture of Chemoreceptor Arrays [PDF]

open access: yes, 2007
The chemoreceptor molecules that mediate chemotactic responses in bacteria and archaea are physically clustered and operate as highly cooperative arrays.
