Faithful segregation of replicated chromosomes is essential for maintenance of genetic stability and seems to be monitored by several mitotic checkpoints. Various components of these checkpoints have been identified in mammals, but their physiological relevance is largely unknown. Here we show that mutant mice with low levels of the spindle assembly(More)
Malignant melanoma is an aggressive, therapy-resistant malignancy of melanocytes. The incidence of melanoma has been steadily increasing worldwide, resulting in an increasing public health problem. Exposure to solar UV radiation, fair skin, dysplastic nevi syndrome, and a family history of melanoma are major risk factors for melanoma development. The(More)
PURPOSE The pathologic features of a variant of granular corneal dystrophy has been described in which the presence of lattice changes in addition to characteristic granular lesions has been documented. The authors investigated the mode of inheritance, natural history, and clinical manifestations of this dystrophy. METHODS A family with this condition was(More)
The authors have defined the specificity of monoclonal antibodies to collagen fragments of basement membrane (BM) and have used these highly specific antibodies to study the human tissue distribution of two novel 28 kd noncollagenous (NC1) peptides (M28 , M28+) compared with those derived from type IV collagen (alpha 1[26 kd] and alpha 2[24 kd] NC1). A(More)
Hemangiopericytomas and solitary fibrous tumors are uncommon neoplasms found in many locations, including the orbit. Both mesenchymal neoplasms share several clinicopathologic features, thus prompting intense debate as to whether they are variants of the same entity or merit separate designations in the orbit. These 2 entities, with the addition of giant(More)
This study involved a group of 407 patients (799 eyes) with pigment dispersion syndrome gathered from a glaucoma population of 9200 patients. The sex distribution was equal. The majority (65%) of patients were myopic. The incidence of retinal detachment was 6.4%. No patients were black, but 5 were mulatto. Approximately one-quarter of the patients wih(More)
PURPOSE To measure the concentration of toxic heavy metals in the fluids and tissues of human eyes. DESIGN Laboratory investigation. METHODS Thirty autopsy eyes of 16 subjects were dissected to obtain the aqueous, vitreous, lens, ciliary body, retina, and retinal pigment epithelium/choroid. Concentrations of lead, cadmium, mercury, and thallium in(More)
Cellulose acetate impressions of the ocular surface were obtained for normal eyes, eyes with blepharoconjunctivitis, eyes with keratoconjunctivitis sicca, and eyes with primary ocular surface disease. Normal eyes and eyes with blepharoconjunctivitis had morphologically normal epithelium and goblet cells on the bulbar and palpebral ocular surfaces. Eyes with(More)
The literature presented in this paper argues that our limited ability to maintain energy balance in a weight-reduced state is the product of our difficulty in compensating for the weight loss-induced reduction in total energy expenditure. The end result, translated into the overwhelming complexity of preserving long-term weight loss, is presented as being(More)
