Title: Composition for stimulating the synthesis of the melanic pigment and process for obtaining it
Inventor: MIYARES CAO CARLOS MANUEL
IPC: A61K35/50
Filed: 1999-07-28
Abstract: The present invention relates to the field of human medicine and more specifically to dermatology, and in particular to a composition developed for the stimulation of the synthesis of the melanic pigment of the skin, and consequently for the treatment of vitiligo. The technical object of the present invention is to provide a composition of a natural product useful in the treatment of vitiligo, which has no toxic effects and no relapse. The composition which has been obtained stimulates the synthesis of the melanic pigment of the skin and the reproduction of melanocytes as it was demonstrated through pharmacological assays to which the composition was subjected, producing no serious secondary reaction at all as demonstrated through toxicological, teratological and clinical assays which have been carried out;  the resulting product can be easily obtained and applied, the repigmenting effect starts rapidly after initiating the treatment, said effect being irreversible when stopping its application. The color acquired is identical to the color of areas of normal skin of the patient, but said areas do not increase further the intensity of their coloration after the product has been applied. The product which is obtained can also be used for the treatment of any depigmentation process of the skin, for example depigmentation caused by burns.

Filed: 1999-11-18
Abstract: L'invention concerne la culture de cellules dans des conditions qui stimulent la survie, la prolifération et/ou la différenciation cellulaire. Dans la présente invention, on a découvert que la prolifération était stimulée et l'apoptose réduite lorsque les cellules étaient cultivées dans des conditions à faible teneur en oxygène par rapport aux conditions atmosphériques traditionnellement employées pour la culture cellulaire. On a en outre découvert que la différenciation de précurseurs vers des destinées spécifiques était également améliorée dans des conditions appauvries en oxygène, où un nombre et une fraction bien supérieurs de neurones dopaminergiques étaient obtenus lorsque des précurseurs mésencéphaliques se développaient et étaient différenciés dans une atmosphère pauvre en oxygène. Ainsi, à des niveaux d'oxygène plus physiologiques, la prolifération et la différenciation de précurseurs du système nerveux central se trouve améliorée tandis que les conditions à faible teneur en oxygène sont utiles pour la génération ex vivo de types de neurones spécifiques. L'invention concerne également des méthodes et des compositions exploitant ces découvertes.

Title: Waste water filtration tank
Inventor: COWAN ANTHONY
IPC: B01D29/01
Filed: 2000-04-14
Abstract: A waste water filtration tank (1) receives waste water under hydrostatic pressure. The tank (1) collects solids using a filter screen (7). When the screen (7) becomes clogged with collected solids, liquid is forced into a float chamber (6) which contains a float (13). As waste water collects in th e float chamber (6), the float (13) rises, as do a beam member (14) and a pair  of rod members (19) to which the float (13) is attached. When the float (13)  reaches a predetermined level, cams contained on the rising rod members (19)  act on spring-loaded latches, opening the latches and permitting a spring loaded sleeve (20) and reservoir gate (17) to rise, opening the reservoir outlet (12). Accumulated solids are then drained from the reservoir and the backwash from the screen chamber (2) also clears the clogged screen (7).</SD OAB>
