A 62-year-old woman was referred for evaluation of a nonhealing epithelial defect of the left eye. Examination also revealed left upper lid ptosis, cicatricial lagophthalmos, and palpable lid masses. With probing, the patient admitted to recent history of lobular carcinoma and remote history of ductal carcinoma of the breast. Imaging showed abnormal tissue in the left extraconal orbit involving the lacrimal gland. After orbitotomy and biopsy of the mass, pathology specimens returned consistent with metastatic carcinoma of the left orbit with breast as the site of the primary tumor. The patient completed palliative radiation therapy and chemotherapy. Amniotic membranes were placed to promote healing of the persistent epithelial defect with good response. Unfortunately, the patient died approximately 1 year after her initial presentation secondary to her oligometastatic disease. There is a wide spectrum of clinical manifestations associated with orbital metastasis. Careful consideration must be given to cancer patients with ophthalmologic complaints.

To report the cosmetic, clinical, and visual outcomes of a combined surgical approach for treating a corneal/limbal dermoid using excision and a three-layered amniotic membrane graft with fibrin glue. An 18-year-old female presented with impaired vision and ocular discomfort caused by a prominent dome-shaped limbal congenital dermoid on the inferotemporal cornea, resulting in a significant aesthetic concern. A full assessment, including refraction, best-corrected visual acuity (BCVA), corneal topography, aberrometry and anterior segment OCT (AS-OCT) was conducted to plan the surgical approach.

Molar incisor hypomineralization (MIH) is a developmental defect that affects the enamel tissue of permanent teeth. Clinicians may observe a range of opacities in the affected teeth, varying from white to creamy, yellow, and brown. Of particular interest is an etiology of MIH that has not been rigorously elucidated.

The cystic fibrosis transmembrane conductance regulator (CFTR) is an anion channel that is dysfunctional in individuals with cystic fibrosis (CF). The permeability of CFTR can be experimentally manipulated though different mechanisms, including activation via inducing the phosphorylation of residues in the regulatory domain as well as altering the gating/open probability of the channel. Phosphorylation/activation of the channel is achieved by exposure to compounds that increase intracellular cAMP, with forskolin and IBMX commonly used for this purpose.

In periparturient dairy cows, high non-esterified fatty acids (NEFAs) caused by a severe negative energy balance induce oxidative stress and metabolic dysfunction, which pose a severe challenge to the dairy industry. Resveratrol (RES) is a polyphenolic compound with antioxidant, anti-inflammatory and multiple other physiological effects. However, its effect on oxidative damage triggered by NEFAs in bovine mammary epithelial cells is rarely reported.

Liquid biopsy methods have gained prominence as minimally invasive tools to improve cancer treatment outcomes. Circulating tumor cells (CTCs) offer valuable insights into both primary and metastatic lesions. However, validating the CTC test results requires confirmation that the detected cells originate from cancer tissue.
