Age-related macular degeneration (AMD) ranks third among the leading causes of visual impairment with a blindness prevalence rate of 8.7%. Despite several treatment regimens, such as anti-angiogenic drugs, laser therapy, and vitamin supplementation, being available for wet AMD, to date there are no FDA-approved therapies for dry AMD. Substantial evidence implicates mitochondrial damage and retinal pigment epithelium (RPE) cell death in the pathogenesis of AMD. However, the effects of AMD mitochondria and Humanin G (HNG), a more potent variant of the mitochondrial-derived peptide (MDP) Humanin, on retinal cell survival have not been elucidated...

Terrestrial eggs have evolved repeatedly in tropical anurans exposing embryos to the new threat of dehydration. Red-eyed treefrogs, Agalychnis callidryas, lay eggs on plants over water. Maternally provided water allows shaded eggs in humid sites to develop to hatching without rainfall, but unshaded eggs and those in less humid sites can die from dehydration. Hatching responses of amphibian eggs to dry conditions are known from two lineages with independent origins of terrestrial eggs. Here, we experimentally tested for dehydration-induced early hatching in another lineage (Agalychnis callidryas, Phyllomedusidae), representing a third independent origin of terrestrial eggs...

PURPOSE: The SANSIKA study evaluated the efficacy/safety of 0.1% (1 mg/mL) cyclosporine A cationic emulsion (CsA CE) for treating dry eye disease (DED) with severe keratitis. The double-masked phase demonstrated that CsA CE was effective in reducing corneal damage and ocular surface inflammation, and was well-tolerated over 6 months. Here we report efficacy and safety findings of SANSIKA's open-label extension (OLE). METHODS: In this multicenter, double-masked, phase III study, patients with severe DED (corneal fluorescein staining [CFS] grade 4, modified Oxford scale) were randomized to once-daily CsA CE (Ikervis®) or its vehicle for 6 months, followed by 6-month open-label, once-daily CsA CE (CsA CE/CsA CE and vehicle/CsA CE groups)...

Idiopathic pulmonary fibrosis (IPF) is one of the most common idiopathic interstitial pneumonia. The main symptoms for IPF are dry cough and exertional shortness of breath, which is worsen gradually with the development of pulmonary fibrosis. Patients with IPF often suffer from sleep disordered breathing (SDB). Sleep architecture for these patients including the sleep efficiency, deep sleep, rapid eye movement sleep and arousal index, are changed, which seriously affects the quality of life. In the absence of effective therapies, optimizing the quality of life may become a major therapeutic target for IPF...

We have developed a one-step method to synthesize carbon quantum dots (CQDPAs) from biogenic polyamines (PAs) as an antibacterial agent for topical treatment of bacterial keratitis (BK). CQDs synthesized by direct pyrolysis of spermidine (Spd) powder through a simple dry heating treatment exhibit a solubility and yield much higher than those from putrescine and spermine. We demonstrate that CQDs obtained from Spds (CQDSpds) possess effective antibacterial activities against non-multidrug-resistant Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonella enterica serovar Enteritidis bacteria and also against the multidrug-resistant bacteria, methicillin-resistant S...

Dry eye can damage the ocular surface and result in mild corneal epithelial defect to blinding corneal pannus formation and squamous metaplasia. Significant progress in the treatment of dry eye has been made in the last two decades; progressing from lubricating and hydrating the ocular surface with artificial tear to stimulating tear secretion; anti-inflammation and immune regulation. With the increase in knowledge regarding the pathophysiology of dry eye, we propose in this review the concept of ocular surface microenvironment...

PURPOSE: Preservatives are used in multi-dose ophthalmic topical medications in order to prevent contamination by bacteria and fungi. However, prolonged use of preserved eye drops, as it may happen in dry eye or glaucoma, may damage cells of the ocular surface. Therefore, an important goal is to find preservatives with low toxicity which are mild to host cells, still able to prevent drug contamination so to maintain their sterility and efficacy. Hence, aim of this study has been to compare the relative toxicity on a rabbit corneal cell line of a new preservative, made by the association of N-hydroxy-methyl-glycinate (NIG) with disodium-ethylene diamine tetra-acetate (EDTA), with other known and widely used eye-drops preservatives...
