The effect of type 2 diabetes on the olfactory bulb structure of Wistar rats [PDF]

یافته‌های نوین در علوم زیستی, 2023
Olfaction, the sense of smell, plays an important role in the individual's safety, nutrition, social interactions, sexual function, and quality of life. Diabetes mellitus, which affects more than 400 million people worldwide, is associated with olfactory

Assessment of olfactory nerve by SPECT-MRI image with nasal thallium-201 administration in patients with olfactory impairments in comparison to healthy volunteers. [PDF]

PLoS ONE, 2013
PURPOSE: The aim of this study was to assess whether migration of thallium-201 ((201)Tl) to the olfactory bulb were reduced in patients with olfactory impairments in comparison to healthy volunteers after nasal administration of (201)Tl.

Olfactory Optogenetics: Light Illuminates the Chemical Sensing Mechanisms of Biological Olfactory Systems

Biosensors, 2021
The mammalian olfactory system has an amazing ability to distinguish thousands of odorant molecules at the trace level. Scientists have made great achievements on revealing the olfactory sensing mechanisms in decades; even though many issues need ...

Neural connectivity predicts spreading of alpha-synuclein pathology in fibril-injected mouse models: Involvement of retrograde and anterograde axonal propagation. [PDF]

, 2020
In Parkinson's disease, some of the first alpha-synuclein aggregates appear in the olfactory system and the dorsal motor nucleus of the vagus nerve before spreading to connected brain regions.

COVID-19-induced anosmia associated with olfactory bulb atrophy

Neuroradiology, 2020
As the global COVID-19 pandemic evolves, our knowledge of the respiratory and non-respiratory symptoms continues to grow. One such symptom, anosmia, may be a neurologic marker of coronavirus infection and the initial presentation of infected patients ...

Evidence of SARS-CoV2 Entry Protein ACE2 in the Human Nose and Olfactory Bulb

bioRxiv, 2020
Usually, pandemic COVID-19 disease, caused by SARS-CoV2, presents with mild respiratory symptoms such as fever, cough but frequently also with anosmia and neurological symptom.

Diesel exhaust inhalation exposure induced toxicity on olfactory bulb in mice through inflammatory response mediated by activating glial cells

环境与职业医学, 2023
BackgroundAir pollution is related to the occurrence and development of mental diseases. Olfactory bulb damage might be the potential prodromal symptom and sign of these diseases.

α-synuclein inclusions are abundant in non-neuronal cells in the anterior olfactory nucleus of the Parkinson’s disease olfactory bulb

Scientific Reports, 2020
Reduced olfactory function (hyposmia) is one of the most common non-motor symptoms experienced by those living with Parkinson’s disease (PD), however, the underlying pathology of the dysfunction is unclear.

Olfactory bulb surroundings can help to distinguish Parkinson’s disease from non-parkinsonian olfactory dysfunction

NeuroImage: Clinical, 2020
Background: The olfactory bulb is one of the first regions of insult in Parkinson’s disease (PD), consistent with the early onset of olfactory dysfunction. Investigations of the olfactory bulb may, therefore, help early pre-motor diagnosis.

Nicotinic cholinergic regulation of olfactory bulb blood flow response in aged rats

Journal of Physiological Sciences, 2023
In our previous research, we had demonstrated the crucial role of neuronal nicotinic acetylcholine receptors (nAChRs) in potentiation of the olfactory bulb blood flow response to olfactory stimulation in adult rats. The present study examined the effects
