Isolation of human adult olfactory sphere cells as a cell source of neural progenitors

Stem Cell Research, 2015
Olfactory stem cells are generated from olfactory mucosa. Various culture conditions generate olfactory stem cells that differ according to species and developmental stage and have different progenitor or stem cell characteristics. Olfactory spheres (OSs)

Health risk assessment of heavy metal accumulation in fruits exposed to geothermal waters: a case study and global implications

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The present study investigated the potential health risks of heavy metals (HMs) in the fruits and leaves of mulberry and sour cherry trees exposed to water from Sivas geothermal basin (Turkey). RESULTS The target HMs were ranked according to their hazard index as: Cd < Pb < Zn < Cu < Ni < Mn < Cr. The total hazard index for mulberry

Nicotine as an odorant : a biochemical and electrophysiological study of receptors for nicotine in the olfactory epithelium of the rat [PDF]

The results suggest that nicotine vapour stimulates an in vitro olfactory preparation in three strains of rat and two strains of mouse, in a manner similar to known odorants.

Anticancer drug vinblastine sulphate induces transient morphological changes on the olfactory mucosa of the rabbit

, 2012
Vinblastine sulphate (VBS) is an anticancer drug that acts by disrupting microtubule dynamics of highly mitotic tissue cells. The consequences of VBS on the olfactory mucosa (OM), a tissue with high mitotic numbers, are not clearly understood.

Mechanisms of pattern processing in olfactory bulb-like circuits [PDF]

, 2010
The scope of brain research spans several orders of magnitude ranging from small groups of amino acid residues in ion channels to fMRI signals reflecting activity averaged over thousands of neurones. From a theoreticians point of view very interesting

SB203580, a p38MAPK inhibitor, attenuates olfactory dysfunction by inhibiting OSN apoptosis in AR mice (activation and involvement of the p38 mitogen‐activated protein kinase in olfactory sensory neuronal apoptosis of OVA‐induced allergic rhinitis)

Brain and Behavior, 2019
Objective This study aimed to investigate the effect of the p38 mitogen‐activated protein kinase (p38MAPK) signaling pathway on olfactory mucosa function and apoptosis of olfactory sensory neurons (OSNs) in an allergic rhinitis (AR) mouse model.

Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

Toxicological effects of volatile organic compounds are mediated by aggravated oxidative stress and neuroinflammatory processes in piglets

Toxicology Reports
Anthropogenic and natural sources of volatile organic compounds (VOCs) have been associated with hematological, cardiovascular, and respiratory diseases. VOCs can also track directly from the nose to the olfactory bulb (OB).
