RESUMO
In an age of mass extinctions, confirming the survival of lost species provides rare second chances for biodiversity conservation. The silver-backed chevrotain Tragulus versicolor, a diminutive species of ungulate known only from Vietnam, has been lost to science for almost three decades. Here, we provide evidence that the silver-backed chevrotain still exists and the first photographs of the species in the wild, and urge immediate conservation actions to ensure its survival.

The object of our proposed recherch is to determine the optimal duration of time, sufficient and necessary, to cure leprosy in its different forms. Following are the necessary steps: a meticulous selection of recovered patient (cleaned); a record of different groups of patients in regard to their clinical form and their prevics duration of treatment; cessation of sulfone treatment; follow up of patient ever a period of year. But already the therapy cessation has raide some difficulties, one of which has led us to the use of DDS Placebo
