Anatomo-Clinical Aspects of Retinoblastoma: A Series of 144 Cases.

Retinoblastoma (RB) is the most common intraocular primary malignancy for infants and young children. The tumor is bilateral in 40% of cases and unilateral in 60% of cases. The hereditary form is due to a germinal mutation in the RB1 tumor suppressor gene.

13q interstitial deletion in a moroccan child with hereditary retinoblastoma and intellectual disability: A case report.

Retinoblastoma is the most common malignant tumor of the eye in children (incidence:1/15,000 to 1/20,000 births), with a sex ratio of 1,5/1. Retinoblastoma, in its inherited form, is a disease caused by a syndrome of genetic predisposition to cancer. The RB1 gene, a tumor suppressor gene, is localized at 13q14.

Carotenoids from Foods of Plant, Animal and Marine Origin: An Efficient HPLC-DAD Separation Method.

Carotenoids are important antioxidant compounds, present in many foods of plant, animal and marine origin. The aim of the present study was to describe the carotenoid composition of tomato waste, prawn muscle and cephalothorax and avian (duck and goose) egg yolks through the use of a modified gradient elution HPLC method with a C reversed-phase column for the efficient separation and analysis of carotenoids and their -isomers. Elution time was reduced from 60 to 45 min without affecting the separation efficiency.

Isolation and identification of phospholipid molecular species in alpha wild marine shrimp Penaeus kerathurus muscle and cephalothorax.

The concentration of TL in Penaeus kerathurus muscle and cephalothorax was 1.03+/-0.04 (75.

Evaluation of the VIDAS Listeria (LIS) immunoassay for the detection of Listeria in foods using demi-Fraser and Fraser enrichment broths, as modification of AOAC Official Method 999.06 (AOAC Official Method 2004.06).

A multilaboratory study was conducted to compare the VIDAS LIS immunoassay with the standard cultural methods for the detection of Listeria in foods using an enrichment modification of AOAC Official Method 999.06. The modified enrichment protocol was implemented to harmonize the VIDAS LIS assay with the VIDAS LMO2 assay.
