Current Insight into Human Ornithine Aminotransferase: A Review

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Human ornithine aminotransferase (hOAT) is a mitochondrial matrix pyridoxal‐5′‐phosphate enzyme (PLP) that catalyzes the reversible transfer of the δ‐amino group of L‐ornithine (L‐Orn) to α‐ketoglutarate (α‐KG) yielding glutamate‐5‐semialdehyde (GSA) and glutamate. GSA is prone to cyclize to Δ1‐pyrroline‐5‐carboxylate.

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...

Clinical reasoning in feline non‐ambulatory tetraparesis or tetraplegia: Which combination of clinical information is useful?

Veterinary Record, EarlyView.
Abstract Background Non‐ambulatory tetraparesis or tetraplegia in cats may constitute a diagnostic challenge for general practitioners. Therefore, this study aimed to evaluate if clinical variables from signalment, history, clinical examination and basic ancillary tests are associated with underlying diagnoses in cats with non‐ambulatory tetraparesis ...

The prechoroidal cleft in neovascular age‐related macular degeneration

Acta Ophthalmologica, EarlyView.
Abstract The prechoroidal cleft is a lenticular, hypo‐reflective space on optical coherence tomography imaging, located between a band of fibrovascular material underneath the retinal pigment epithelium (RPE) and Bruch's membrane. It occurs in 8%–22% of neovascular age‐related macular degeneration (nAMD) eyes, most often with macular neovascularization

Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis

Acta Ophthalmologica, EarlyView.
Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).

Seasonal variation in the incidence of central serous chorioretinopathy: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Central serous chorioretinopathy (CSC) is a chorioretinal disease characterised by serous subretinal fluid (SRF) in the macula, resulting in sudden central vision loss. It predominantly affects working‐age adults, particularly men aged 30 to 60 years.
