A SINE-derived element constitutes a unique modular enhancer for mammalian diencephalic Fgf8. [PDF]

open access: yesPLoS ONE, 2012
Transposable elements, including short interspersed repetitive elements (SINEs), comprise nearly half the mammalian genome. Moreover, they are a major source of conserved non-coding elements (CNEs), which play important functional roles in regulating ...

Clinical neuroanatomy teaching at Peking University Health Science Center: Evolution, current practice, and future direction

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Neuroanatomy has been considered one of the most challenging subjects in medical education, often leading to “neurophobia” and discouraging students from pursuing neurological specialties. At PKUHSC, the curriculum has evolved from a traditional, discipline‐based model to a technology‐enhanced, integrated “Nervous System” module for ...

Melanocortin receptor 3 and 4 mRNA expression in the adult female Syrian hamster brain

open access: yesFrontiers in Molecular Neuroscience, 2023
Melanocortin 3 receptors (MC3R) and melanocortin 4 receptors (MC4R) are vital in regulating a variety of functions across many species. For example, the dysregulation of these receptors results in obesity and dysfunction in sexual behaviors.

Histamine and the mechanisms of nausea and vomiting: Translating the uncertain pharmacology of cyclizine

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Cyclizine is a long‐established, short‐acting drug, registered for preventing motion sickness, post‐operative nausea and vomiting (PONV) and ‘vomiting of known cause’. The latter is not defined but may include pregnancy and patients receiving palliative care, historically accepted without large, controlled trials.

Influence of an Aromatic Amino Acid Decarboxylase Inhibitor on GTP Cyclohydrolase I Activity in the Rat Brain

open access: yesPteridines, 1997
Based on the hypothesis that catecholamine decreases may cause increases in biopterin, we measured the GTP cyclohydrolase I(GTPCH-I) activity and biopterin content in the cerebral cortex, midbrain/diencephalon, cerebeilum, pons/medulla oblongata ...

Oral Administration of D-aspartate, but not of L-aspartate, Reduces Food Intake in Chicks

open access: yesThe Journal of Poultry Science, 2013
In the present study, we determined the effects of oral administration of L- and D-aspartate (L-Asp and D-Asp) on food intake over a period of 2 h after the administration, as well as its effects on the concentration of L- and D-Asp in the brain and ...

Environmentally-relevant concentrations of the antipsychotic drugs sulpiride and clozapine induce abnormal dopamine and serotonin signaling in zebrafish brain

open access: yesScientific Reports, 2022
The presence of drugs in surface and groundwaters adversely affects the physiological function of non-target organisms due special activities that can pose a serious threats to various forms of aquatic life.

Differential sensitivity to SHH signaling and neural crest‐mediated Gas1 expression regulate jaw size during development and evolution

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Developmental control of jaw size is crucial to prevent birth defects and facilitate evolutionary adaptation. We have shown that jaw size is established by neural crest mesenchyme (NCM), which are progenitor cells that migrate into the mandibular primordia and produce the jaws.

Beyond the Fixed Charge: A New On‐Tissue Derivatisation Strategy Employing Photoionisable Chromophores for Mass Spectrometry Imaging of Amino‐Containing Metabolites

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
We introduce a novel chemical derivatisation strategy for the UV‐activated detection of elusive metabolites. Incorporation of a tocopherol‐active chromophore allows for the detection of tagged analytes as photoionised radical cations, selectively induced by a 266 nm laser.

Multi-neuromeric origin of tyrosine hydroxylase-positive neurons within the substantia nigra and ventral tegmental area

open access: yesFrontiers in Neuroanatomy
During early developmental stages, the brain is divided into three primary regions: the forebrain (prosencephalon), the hindbrain (rhombencephalon), and the spinal cord.
