OBJECTIVE: The human corneal epithelium expresses both the insulin-like growth factor type 1 receptor (IGF-1R) and the IGF-1R/insulin receptor (INSR) hybrid. Despite the previous identification of IGF-1 in human tear fluid, little is known regarding the regulation of IGF-1 in tear fluid and its role in corneal epithelial homeostasis. In the present study, we investigated the impact of biological parameters on the concentration of human tear levels of IGF-1. DESIGN: Tear levels of IGF-1 were measured in 41 healthy, human volunteers without any reported symptoms of dry eye...

Dry eye syndrome (DES) is considered as an ocular surface inflammatory disease. Previous studies have shown inflammation plays an important role in the progression and onset of DES. Co-culture of human bone marrow mesenchymal stem cells (HBMSCs) and macrophages showed immunomodulatory effects via regulation of cytokine regulation. Thus, the aim of this study was to investigate the effect of the interaction of these cells on in vitro DES model. The conditioned media (CM) from macrophages, HBMSCs, and HBMSCs + macrophages were treated to human corneal epithelial cells, which showed significant reduction in IL-1α and IL-1β expression levels in HBMSCs + macrophages group...

Work was undertaken to investigate the potential use of housefly (Musca domestica) larvae reared on broiler manure as a source of nutrition for poultry production in the United Kingdom. Nutritional analysis showed that larvae have a high (>45% dry wt.) protein content and a favorable amino acid profile that is rich in key amino acids, such as lysine and methionine. A broiler digestibility trial was carried out to determine the apparent ileal digestibility coefficients (AIDC) and true ileal digestibility coefficients (TIDC) of amino acids (AA) from insect larval meal (ILM) from M...

Purpose/aims: Dry eye is a common multi-factorial disease characterized by tearfilm dysfunction. Diagnosis of dry eye requires documentation of tear status with non-invasive tear break up times (NIBUT), tear meniscal height (TMH), and tearfilm lipid layer. These parameters objectively assess tear stability and indirectly, the functional impact of meibomian gland dysfunction. While it is obvious that portable instrumentation gives broader access than fixed instrumentation, its value would be limited if it is unreliable and its precision and accuracy substantially worse than fixed instruments...

Mitochondrial function is closely linked to numerous aspects of eye health. Imbalance between the creation of energy and the development of reactive oxygen species (ROS) seems to be the cause of the development of mitochondrial dysfunctions. As a result of this energy deficit, the level of oxidative stress in the eye tissues increases, leading to numerous ophthalmic impairments. It is important to distinguish between primary mitochondrial eye diseases and secondary mitochondrial changes. Primary mitochondrial eye diseases, for example Leber's hereditary optic atrophy (LHON), retinitis pigmentosa and chronic progressive external ophthalmoplegia are caused by direct damage to mitochondrial function induced by defective genes, either located on mitochondrial DNA (mtDNA) or the DNA of the nucleus (nDNA)...

Geographic atrophy (GA), the late stage of dry age-related macular degeneration is characterized by loss of the retinal pigment epithelial (RPE) layer, which leads to subsequent degeneration of vital retinal structures (e.g., photoreceptors) causing severe vision impairment. Similarly, RPE-loss and decrease in visual acuity is seen in long-term follow up of patients with advanced wet age-related macular degeneration (AMD) receiving intravitreal anti-vascular endothelial growth factor (VEGF) treatment. Therefore, on the one hand, it is fundamental to efficiently derive RPE cells from an unlimited source that could serve as replacement therapy...

Commensal bacteria play an important role in the formation of the immune system but their role in the maintenance of immune homeostasis at the ocular surface and lacrimal gland remains poorly understood. This study investigated the eye and lacrimal gland phenotype in germ-free and conventional C57BL/6J mice. Our results showed that germ-free mice had significantly greater corneal barrier disruption, greater goblet cell loss, and greater total inflammatory cell and CD4⁺ T cell infiltration within the lacrimal gland compared to the conventionally housed group...

Dry eye disease (DED) is the most common ocular surface diseasenowadays. DED can be divided into different types based on the pathogenesis. The progression of DED is strongly related to chronic ocular surface inflammation, regardless of the type of DED. The corneal Langerhans cells (LC) are the dedicated antigen presenting cells in the ocular surface immune system. Along with further understanding of LC recently, its double-sided functions have been discovered: on one hand, LC phagocytize antigen and induce immune tolerance, and on the other hand, LC process and present antigen, and initiate immune response...

Dry eye is one of the most common ocular problems in ophthalmology clinic. With the change of social environment and people's life style, the prevalence of dry eye disease is increasing. Currently, the diagnosis criteria for dry eye is controversial, diagnosis of dry eye mainly rely on the comprehensive assessment of symptoms and the presence of associated ocular surface signs. However, previous studies have shown a poor correlation between dry eye symptoms and objective clinical signs in patients. Recent studies have found that neuropathic pain plays an important role in the occurrence of discordance between symptoms and signs in dry eye disease...

Intense pulsed light (IPL) is a broad spectrum incoherent light which is produced by high-output xenon lamp. Since the invention of the first-generation IPL in 1994, IPL technology has been developing rapidly and extensively utilized in multiple fields relevant to dermatology across the world. In 2004, the fourth-generation IPL system was introduced with the optimal pulse technology (OPT) and has soon been used for cosmetic purposes all over the world. In 2002, Dr. Toyos found that the meibomian gland dysfunction (MGD) and dye eye disease (DED)symptoms of the rosacea patients who received IPL treatment have been improving significantly, therefore he started to explore the application of IPL system to treatment of dry eye disease...
