Odonto-onycho-dermal dysplasia (OODD), a rare autosomal-recessive inherited form of ectodermal dysplasia including severe oligodontia, nail dystrophy, palmoplantar hyperkeratosis, and hyperhidrosis, was recently shown to be caused by a homozygous nonsense WNT10A mutation in three consanguineous Lebanese families. Here, we report on 12 patients, from 11(More)
PURPOSE The study was performed to determine whether trefoil factor peptides (TFF) and/or mucins are components of dacryoliths and to gain further insight into dacryolith composition and formation. METHODS Twenty dacryoliths found in lacrimal surgery in patients suffering from primary acquired nasolacrimal duct obstruction were analyzed for the presence(More)
PURPOSE To evaluate the role of the preocular riboflavin film in ultraviolet-A (UVA) absorption in corneal collagen crosslinking (CXL). SETTING Eye Laser Institute, Department of Ophthalmology, Martin-Luther-University, Halle, Germany. METHODS The absorption of UVA light was measured in human donor and porcine postmortem corneas with and without(More)
Basic helix-loop-helix (bHLH) transcription factors are important regulators of retinal neurogenesis. In the developing retina, proneural bHLH genes have highly defined expressions, which are influenced by pattern formation and cell-specification pathways. We report here that the tissue-specific bHLH transcription factor Ptf1a (also known as PTF1-p48) is(More)
Interleukin 10 (IL-10) is an immunosuppressive factor and has been detected in tumour cell cultures of renal cell carcinoma and of malignant melanoma. IL-10 has been described as a cytokine of the Th2 response; it is able to suppress antigen-presenting cells (APCs) and may lead to down-regulation of HLA class I and II molecules on dendritic cells and to(More)
BACKGROUND The nasal mucosa is characterized by a multirow high prismatic ciliated epithelium representing the first barrier of the immune defense system against microbial and other environmental pathogenic influences. A number of nonspecific defense mechanisms, including the presence of lactoferrin, peroxidases, proteases, interferons, and lysozymes in(More)
PURPOSE To determine whether the epithelium of the human nasolacrimal ducts contains aquaporins (AQPs), a family of membrane proteins that function as selective pores and are able to transport water, glycerol, and other small solutes across the cell plasma membrane. METHODS Expression of AQPs 0 and 1-10 in human nasolacrimal duct tissue was determined by(More)
The detection of donor-specific anti-HLA antibodies by standard procedures such as complement-dependent cytotoxicity assay (CDC) or flow cytometric (FACS) analysis is limited by its low sensitivity and the quality of the donor cells. Therefore, an ELISA-based technique was employed using solid phase-immobilized monoclonal antibodies to capture HLA class I(More)
Previous studies had shown that donor-specific anti-HLA antibodies may highly influence the survival rate of corneal allografts, although the anterior chamber generally represents an immune-privileged compartment of the eye. We postulated that the introduction of a novel crossmatch procedure for the detection of donor-specific anti-HLA antibodies in(More)
PURPOSE To assess possible cellular damage in the corneal and conjunctival epithelium after corneal cross-linking treatment. METHODS Riboflavin-dextran solution was applied every 5 minutes to the right eyes of 3 rabbits 10 minutes before and 30 minutes during the irradiation with UVA light of 370 nm and an irradiance of 3 mW/cm at the 8- to 10-o'clock(More)
