Transcriptomic profiling of thyroid eye disease orbital fat demonstrates differences in adipogenicity and IGF-1R pathway.

Despite recent advances in the treatment of thyroid eye disease thyroid-related eye disease (TED), marked gaps remain in our understanding of the underlying molecular mechanisms, particularly concerning the insulin-like growth factor-1 receptor (IGF-1R) pathway. To dissect the pathophysiology of TED, we used single-nucleus RNA-Seq to analyze orbital fat specimens from both patients with TED and matched individuals acting as controls. The analysis demonstrated a marked increase in the proportion of fibroblasts transitioning to adipogenesis in the orbital fat of patients with TED compared with that in control patients.

Orbital Septum Posterior to Medial Canthal Tendon Area.

Purpose: To examine the anatomy of the orbital septum posterior to the medial canthal tendon area.

Materials And Methods: We performed 3 anatomical dissections in the present study. The first one was a microscopic study in which exenterated specimens from 6 Japanese cadavers (age from 77 to 93 years at death) were cut inferno-horizontally, including the Müller muscle, medial rectus pulley, and lateral rectus pulley, and stained with Masson's trichrome.

A Comparison of Endoscope-Assisted and Open Frontoorbital Distraction for the Treatment of Unicoronal Craniosynostosis.

Background: Frontoorbital distraction osteogenesis (FODO) is an established surgical technique for patients with unicoronal craniosynostosis. The authors' institution has used an endoscope-assisted technique (endo-FODO) in recent years to decrease cutaneous scarring and lessen the impact on the functional growth matrix. This study compared perioperative outcomes in patients undergoing endo-FODO to those in patients undergoing the traditional coronal approach.

Novel immunoinflammatory blood markers in Graves' orbitopathy: insights into activity and severity.

Objective: This prospective case-control study examined the novel immunoinflammatory markers obtained from blood counts of patients with Graves' orbitopathy (GO), Graves' disease (GD) and healthy subjects.

Methods: Demographic data, white cell count parameters, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), platelet-to-neutrophil ratio (PNR), red cell distribution width (RDW), RDW-to-platelet ratio (RDW/PLT), MPV-to-lymphocyte ratio (MPV/ALC), eosinophil-to-lymphocyte ratio (ELR) and systemic immune-inflammatory index (SII) were evaluated. The European Group on Graves Orbitopathy scale and Clinical Activity Score were used for clinical activity and severity assessment.

Linsitinib inhibits IGF-1-induced cell proliferation and hyaluronic acid secretion by suppressing PI3K/Akt and ERK pathway in orbital fibroblasts from patients with thyroid-associated ophthalmopathy.

Thyroid-associated ophthalmopathy (TAO), an autoimmune disorder of the retrobulbar tissue, is present in up to 50 percent of Graves's hyperthyroidism patients. Insulin-like growth factor 1 receptor (IGF-1R) has received attention as a target for the development of therapeutic agent for TAO. IGF-1R and TSHR (thyroid stimulating hormone receptor) interact with each other to form a physical or functional complex, further promoting the development of TAO.

The value of signal intensity ratios of orbital tissue to white matter of orbital MRI in evaluating graves' orbitopathy.

Absract: PURPOSE: To investigate the signal intensity ratio (SIR) of orbital tissue to white matter in orbital magnetic resonance imaging (MRI) for assessing graves' orbitopathy (GO).

Methods: This study enrolled a total of 42 patients (79 eyes) with GO as the GO group, 10 patients (20 eyes) diagnosed with graves' disease (GD) without orbitopathy during the same period as the GD group, and 23 normal individuals with negative MRI results and no thyroid or eye diseases as the healthy control (HC) group. The signal intensity of the lacrimal gland (LG), extraocular muscle (EOM), ipsilateral temporal muscle (TM), ramus mandibulae, and white matter (WM) on MRI images was measured.

Structure-based virtual screening of Trachyspermum ammi metabolites targeting acetylcholinesterase for Alzheimer's disease treatment.

In recent decades, Alzheimer's disease (AD) has garnered significant attention due to its rapid global prevalence. The cholinergic hypothesis posits that the degradation of acetylcholine by acetylcholinesterase (AChE) contributes to AD development. Despite existing anti-AChE drugs, their adverse side effects necessitate new agents.

A New Approach for Orbital Wall Reconstruction in a Rabbit Animal Model Using a Hybrid Hydroxyapatite-Collagen-Based Implant.

Reconstructing the orbit following complex craniofacial fractures presents significant challenges. Throughout the years, several materials have been used for orbital reconstruction, taking into account factors such as their durability, compatibility with living tissue, cost efficiency, safety, and capacity to be adjusted during surgery. Nevertheless, a consensus has not yet been reached on the optimal material for orbital restoration.

Transcutaneous Lower Blepharoplasty with Midface Lift by Malar Fat Suspension to Lateral Part of Infraorbital Wall.

Alterations in surface-based brain morphometry in men with opioid use disorder.

Cortical differences in thickness, folding, and complexity may reflect synaptic pruning and myelination alterations. Individuals with opioid use disorder (OUD) may demonstrate differences in these cortical metrics due to neurodevelopmental aberrations or early opioid exposure. We compared the cortical metrics between individuals with OUD and controls.

Dermoid Cyst of Conjunctival Origin Attached to the Tarsus in a Pediatric Patient.

Dermoid cysts of cutaneous origin are common orbital lesions, whereas dermoid cysts of conjunctival origin are rare. The authors present a case of a dermoid cyst of conjunctival origin that was attached to the tarsus in a pediatric patient. A 2-year-old boy presented to the clinic with an approximately 2 cm in diameter mobile nodule in the upper eyelid on the temporal side that distorted the eyelid architecture with temporal ptosis.

A STAG2-PAXIP1/PAGR1 axis suppresses lung tumorigenesis.

The cohesin complex is a critical regulator of gene expression. STAG2 is the most frequently mutated cohesin subunit across several cancer types and is a key tumor suppressor in lung cancer. Here, we coupled somatic CRISPR-Cas9 genome editing and tumor barcoding with an autochthonous oncogenic KRAS-driven lung cancer model and showed that STAG2 is uniquely tumor-suppressive among all core and auxiliary cohesin components.

IgG4-related disease for the hematologist.

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated disease with many important manifestations in hematopoietic and lymphoid tissue. IgG4 is the least naturally abundant IgG subclass, and the hallmark feature of IgG4-RD is markedly increased IgG4-positive plasma cells (with an IgG4 to IgG ratio >40%) in affected tissue, along with elevated polyclonal serum IgG and IgG4 in most patients. Histological diagnosis is essential, and other key features include storiform fibrosis, lymphoplasmacytic infiltrate, tissue eosinophilia, and obliterative phlebitis.
