Hypogonadotropic Hypogonadism Before and After Transsphenoidal Surgery for Non‐Functioning Pituitary Adenoma

Clinical Endocrinology, EarlyView.
ABSTRACT Objective The effect of transsphenoidal surgery (TSS) on the hypothalamic‐pituitary‐gonadal (HPG) axis in patients with non‐functioning pituitary adenomas (NFPA) is underexplored, especially in women. Our aim was to investigate the HPG axis function before and after TSS, its association with quality of life (QoL), and to identify factors that ...

Perturbations of microRNA function in mouse dicer mutants produce retinal defects and lead to aberrant axon pathfinding at the optic chiasm.

PLoS ONE, 2010
BackgroundDuring development axons encounter a variety of choice points where they have to make appropriate pathfinding decisions. The optic chiasm is a major decision point for retinal ganglion cell (RGC) axons en route to their target in order to ...

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Uncommon cavernous malformation of the optic chiasm: a case report

European Journal of Medical Research, 2012
Cavernous malformation (CM) is a vascular malformation disorder characterized by a berry-like mass of expanded blood vessels. CM, originating from the optic chiasm. usually leads to chiasma syndrome presenting with bitemporal hemianopsia.

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

Journal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...

Retinopathy of Prematurity Is Associated With Reduced Thalamic Volume and Impaired Neurodevelopment. A Cohort Study

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Background Retinopathy of prematurity (ROP) is a neurovascular disorder that may affect not only the retina but also the brain structures involved in visual processing. The relationship between ROP severity and the volumetric development of these regions remains unclear.

Management of Optic Chiasma/Hypothalamic Gliomas

Pediatric Neurology Briefs, 2002
A retrospective chart review of all newly diagnosed tumors involving the optic chiasm from 1982-1996 was performed at British Columbia’s Children’s Hospital, Vancouver, Canada.

Integrative revision of the Australian carrion‐breeding Calliphorinae (Diptera: Calliphoridae): Revision of the Calliphora stygia‐ and ochracea‐groups

Medical and Veterinary Entomology, EarlyView.
The Australian carrion‐breeding Calliphorinae are revised using an integrative approach combining morphology and mitogenomics. A new taxonomic key, morphological images and verified mitogenomic data, including COX1 barcodes, are provided to support the identification of species.

Nogo receptor inhibition enhances functional recovery following lysolecithin-induced demyelination in mouse optic chiasm.

PLoS ONE, 2014
BackgroundInhibitory factors have been implicated in the failure of remyelination in demyelinating diseases. Myelin associated inhibitors act through a common receptor called Nogo receptor (NgR) that plays critical inhibitory roles in CNS plasticity ...

Physiological cerebrospinal fluid interactions between brain and eye structures are altered after long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight represents an extreme challenge, triggering adaptive responses including spaceflight‐associated neuro‐ocular syndrome, characterized by diminished visual acuity and ocular changes, which is a significant health risk for Mars missions.
