The regulation of stem cell fate and its application in neural regeneration

Interdisciplinary Medicine, EarlyView.
Regulating stem cell fate is crucial for neural regeneration. This review summarizes key physical, biological, and chemical strategies and their applications in repairing nerve injuries, providing new insights for regenerative medicine. Abstract Regulating the fate of stem cells (SCs) is a key technical problem in the field of regenerative medicine and

Raised endogenous monoamine oxidase inhibitor output in postwithdrawal alcoholics: effects of L-dopa and ethanol.

, 1982
Urinary output of endogenous monoamine oxidase inhibitor was significantly greater in a group of postwithdrawal alcoholics than in controls. An oral dose of 0.5 g of L-dopa reduced output to control values in the alcoholics, but in the controls ...

Inability of Murine Melanoma "Tyrosinase" (Dopa Oxidase) To Oxidize TYrosine in the Presence or Absence of Dopa or Dihydroxyfumarate Cofactor

, 1973
Soluble “tyrosinase” was isolated from Harding Passey melanoma and its ability to oxidize tyrosine or dopa to melanin was studied by quantitative analysis of tyrosine consumption and dopa formation and by spectrophotometric recording of dopachrome ...

Alpha‐Synuclein Promotes Anterograde Vesicle Transport in Melanocytes and Melanoma Cells: A Pro‐Survival Function

Journal of the Chinese Chemical Society, EarlyView.
Model for how α‐syn modulates the positioning of endolysosomes in melanoma cells. (a) α‐syn tethers endolysosomes to the plasma membrane, a last step in anterograde transport. (b) Loss of α‐syn expression causes the loss of the tethering function, which leads to perinuclear vesicle clustering. Reproduced from the open access article.

l-Dopa induced dyskinesias in Parkinsonian mice: Disease severity or l-Dopa history

, 2015
In Parkinson’s disease, the efficacy of l-Dopa treatment changes over time, as dyskinesias emerge with previously beneficial doses. Using MitoPark mice, that models mitochondrial failure in dopamine (DA) neurons and mimics the progressive loss of ...

Models of probabilistic category learning in Parkinson's disease: Strategy use and the effects of L-dopa

, 2010
Probabilistic category learning (PCL) has become an increasingly popular paradigm to study the brain bases of learning and memory. It has been argued that PCL relies on procedural habit learning, which is impaired in Parkinson's disease (PD). However, as

Beyond Skin and Eyes: The Medical and Social Burden of Oculocutaneous Albinism in Africa: A Narrative Review

JEADV Clinical Practice, EarlyView.
ABSTRACT Oculocutaneous albinism (OCA) is a genetic disorder found worldwide, but its impact is particularly pronounced in the African continent. This results from both a higher prevalence and the persistent myths and superstitions surrounding the condition in many African communities.

Proteomics of Nitrotyrosine: Integrating Mass Spectrometry and Immunodetection in Redox‐Driven Pathology

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Nitrooxidative stress, driven by excess reactive nitrogen species like peroxynitrite, contributes to the pathogenesis of many chronic diseases. Among its molecular footprints, 3‐nitrotyrosine (3NT) has emerged as a biologically relevant marker of protein nitration.
