Treatments for Biomedical Abnormalities Associated with Autism Spectrum Disorder
Frontiers in Pediatrics, 2014 Recent studies point to the effectiveness of novel treatments that address physiological abnormalities associated with autism spectrum disorder (ASD). This is significant because safe and effective treatments for ASD remain limited.

Advanced Science, Volume 13, Issue 25, 4 May 2026.The schematic diagram illustrates the roles of novel immune checkpoints, immunomodulatory factors, cell death and multimodal technologies in cancer immunotherapy. Abstract Cancer immunotherapy has redefined cancer treatment. However, the molecular and cellular basis of immune evasion and therapeutic resistance remains incompletely understood.

p38(MAPK)/p53 signalling axis mediates neuronal apoptosis in response to tetrahydrobiopterin-induced oxidative stress and glucose uptake inhibition: implication for neurodegeneration. [PDF]
, 2010 BH4 (tetrahydrobiopterin) induces neuronal demise via production of ROS (reactive oxygen species). In the present study we investigated the mechanisms of its toxicity and the redox signalling events responsible for the apoptotic commitment in SH-SY5Y ...

Pteridines, 2002 Tetrahydrobiopterin (BH4) is one of the cofactors for nitric oxide synthase (NOS), and also has a protective effect against reactive oxygen species (ROS)- and/or nitric oxide (NO)-induced cytotoxicities. Lipopolysaccharide (LPS) induces NO production and

A Novel Multimodal LC–MS/MS Panel for the Comprehensive Diagnosis of Neurometabolic Disorders in CSF
Journal of Inherited Metabolic Disease, Volume 49, Issue 3, May 2026.ABSTRACT Metabolic testing of cerebrospinal fluid (CSF) is essential for early diagnosis of neurometabolic disorders. However, the large number of differential diagnoses, the phenotypic variance within a clinical picture, and the disease rarity complicate targeted metabolic diagnostics.

Journal of Inherited Metabolic Disease, Volume 49, Issue 3, May 2026.ABSTRACT Phenylketonuria (PKU) is a rare metabolic disorder causing elevated phenylalanine (PHE) levels requiring lifelong dietary or pharmacological management and regular monitoring. Current PHE monitoring methods, such as tandem mass spectrometry (FIA‐MS/MS), are laboratory and sample transport‐dependent, leading to delays in obtaining results. This

Pteridines, 1997 We examined the inhibitory effect of tetrahydrobiopterin (BPH4) on L-β-(3,4-dihydroxyphenyl)alanine (DOPA)-induced cytotoxicity in PC-12 cells. First in vitro inhibitory efficacy of BPH4 on lipid peroxidation induced by Fe3+-DOPA complex was confirmed by
