1. Ciliary body malignant melanoma: A dilemma on staging
Resumo Melanomas coroidais são os tumores malignos intra-oculares primários mais comuns em adultos. Eles tendem a ser mais malignos; devido à sua localização ser escondida por detrás da íris eles não podem ser detectados até se tornarem maiores. A estratégia terapêutica está relacionada com tamanho, extensão, número e localização dos padrões

2. GTPases Rho e o potencial regenerativo da retina de mamíferos / Rho GTPases and the regenerative potential of the mammalian retina
Ciliary Body (CB) is a potential source of stem cells in the adult retina, but its activation is still unknown. Rho GTPases play a role in actin-based cytoskeleton reorganization, regulate signaling pathways and gene transcription, cell survival and cell proliferation. In this study we investigated the expression of Rho GTPases in CB cells and their role on

3. Investigação da ação neuroprotetora do fator neurotrofico ciliar (CNTF) conjugado com peptideo contendo dominio de translocação de proteina (PTD) / Investigation of neuroprotective action of ciliary neurotrophic factor (CNTF) fused to a protein transduction domain (PTD)
Ciliary neurotrophic factor (CNTF) is known as a neuroprotective agent on motoneurons after peripheral nerve section in neonatal rats and adult mice. However, side effects like weight loss and caquexia have limited its clinical use. A promising approach for the avoidance of such side effects is the fusion of a protein transduction domain (PTD) with CNTF. Pre

4. Immunohistochemical characterization of the chick marginal retina
The retina is a highly differentiated tissue with a complex layered structure that has been extensively characterized. However, most of the previous studies focused on the histology of the central retina while little is known about the cellular composition, organization and function of the marginal retina. Recent research has identified a subpopulation of mu

5. Functional properties of the protein transduction domais associated ciliary neurotrophic factor : analysis of its effects on energy metabolism regulating hypothalamic regions / Propriedades funcionais do fator neurotrofico ciliar associado a um dominio de translocação de proteina : analise de seus efeitos sobre regioes hipotalamicas reguladoras do metabolismo energetico
O Fator Neurotrófico Ciliar (CNTF) é uma neurocitocina com múltiplas atividades biológicas, sendo notável sua habilidade de proteger motoneurônios. Entretanto, a administração de CNTF leva à redução de peso corporal. Por outro lado, a administração do CNTF fusionado a um Domínio de Transdução de Proteínas (PTD), denominado TAT-CNTF, é capaz

6. Alterações na superfície ocular de coelhos tratados com formulações do herbicida ácido diclorofenoxiacético (2,4 d), utilizando a graduação do teste ocular de draize
Ocular irritation test is required by the Brazilian government authorities during the registration process of pesticide products, and it is essential for its toxicological classification. The present study evaluated the clinical and microscopic changes in the eye surface of rabbits after treatment with four pesticide formulations containing the herbicide 2,4

7. The anti-IRBP IgG1 and IgG2a response does not correlate with susceptibility to experimental autoimmune uveitis
Susceptibility to experimental autoimmune uveitis (EAU) in inbred mice has been associated with a dominant Th1 response. Elevated anti-inter-photoreceptor retinoid-binding protein (anti-IRBP) IgG2a/IgG1 antibody ratios have been implicated as candidate markers to predict disease severity. In the present study, both the anti-IRBP antibody isotype and severity

8. Neurilemmoma of the ciliary body: report of a case.
A case of ciliary body neurilemmoma is described. This neoplasm is extremely rare in the uveal tract and has been reported only once in the ciliary body. After extensive clinical studies of the rapidly growing tumour enucleation was performed. Subsequent histological examination showed typical features of highly vascular benign neurilemmoma. The main clinica

9. Ring melanoma of the iris and ciliary body.
The case is described of a tumour of the iris and ciliary body--a ring type melanoma--primarily diagnosed and treated as pigmentary glaucoma.

10. Ciliary body enlargement and cyst formation in uveitis.
BACKGROUND: Acute anterior uveitis has diverse causes and systemic associations. Inflammation is predominantly localised to the iris and pars plicata. Little is known about the in vivo effects of uveitis on ciliary body anatomy. METHODS: Bilateral, high frequency, high resolution, ultrasound biomicroscopy was performed on consecutive patients with unilateral

11. Schwannoma of the ciliary body treated by block excision.
A 26-year-old man developed a non-pigmented ciliary body tumour of his right eye. A 7 mm block excision and tectonic corneoscleral graft were performed. The excised tissue was studied using histopathological, immunohistochemical, and electron microscopic techniques. The tumour revealed characteristic features of a Schwann cell neoplasm including Antoni A and

12. Enzymes of the γ-Glutamyl Cycle in the Ciliary Body and Lens
The enzymes of the γ-glutamyl cycle have been found in rabbit ciliary body and, except for 5-oxoprolinase, also in the ocular lens. Histochemical studies show that γ-glutamyl transpeptidase is localized mainly in the basal portions of the epithelial cells of the ciliary body; the findings are similar to those observed in the chloroid plexuses. The histoche
