Pseudocapsular exfoliation occurs in most races and countries but appears to be particularly common in Norway and in the Eastern European and Mediterranean countries. It is rare in American Negroes, only two cases having been reported (Gradle and Sugar, 1947), and in Negroes in the West Indies (Connell, I970), and has not been reported in Negroes elsewhere outside South Africa (Bartholomew, I97...

Neutrinos may be pseudo-Dirac states, such that each generation is actually composed of two maximally mixed Majorana neutrinos separated by a tiny mass difference. The usual active neutrino oscillation phenomenology would be unaltered if the pseudo-Dirac splittings are deltam(2) less, similar 10(-12) eV(2); in addition, neutrinoless double beta decay would be highly suppressed. However, it may ...

PURPOSE To investigate possible genetic associations of matrix metalloproteinase-1 (MMP1) and MMP3 gene polymorphisms with exfoliation syndrome (XFS) with (XFS/+G) and without (XFS/-G) glaucoma in a cohort of Greek patients. METHODS A total of 182 unrelated Greek patients with XFS, including 92 patients with XFS/+G, and 214 unrelated age- and gender-matched controls were enrolled in the study...

Papillon-Lefevre syndrome is a rare autosomal recessive genetic disorder. The clinical manifestations include palmer planter hyperkeratosis with precocious progressive periodontal disease that results in premature exfoliation of primary and permanent dentitions. Patients are often edentulous at an early age. This is a case report of prosthodontic rehabilitation of a 15-year-old girl with Papill...

PURPOSE To evaluate the association profiles of the lysyl oxidase-like 1 (LOXL1) gene polymorphisms with exfoliation syndrome in a Chinese population. METHODS Fifty unrelated patients with exfoliation syndrome and 125 control subjects were included. Genotypes of the three single nucleotide polymorphisms (SNPs) of LOXL1 (rs1048661, rs3825942, and rs2165241) were analyzed by direct sequencing, ...

Aim To examine the ageand gender-specific prevalent and 5-year incident risk of developing exfoliation
