There are, however, still differences between the European GMO regulations and the GMO regulations as they have been formulated in other parts of the world.

A population based survey of blindness and eye disease has been conducted throughout the whole country of The Gambia, and 8174 people were examined. The prevalence of blindness (best acuity less than 3/60) was 0.7% and low vision (6/24-3/60) 1.4%. The causes of blindness were cataract (55%), non-trachomatous corneal opacity/phthisis (20%), and trachoma(More)
Ninety-nine young Gambian children were studied for 61 weeks. About half of them had trachoma at the outset, and 80% of the remainder acquired the disease while under observation. IgG trachoma antibody in the serum and IgG and IgA antibodies in the conjunctival secretions (CS) were titrated by an indirect immunofluorescence method. In serum samples obtained(More)
General aspects regarding the presence of nonsymbiotic haemoglobin in plants are presented with the emphasis on those related to its function. As it becomes apparent that the nonsymbiotic haemoglobins are widespread across the plant kingdom and that they represent a more primitive and evolutionary older form of the plant globin genes, the question of their(More)
Two groups of children were treated daily with 12.5 or 25 mg diethylcarbamazine for five months and a further group with 12.5 mg daily for seven weeks; 88 children completed the course. The trial was under constant supervision and ophthalmic and parasitological examinations were carried out at approximately one-month intervals. The acceptability of the drug(More)
