One of the simplest and most effective flea repellents are eucalyptus leaves. For some reason fleas are averse to their smell. Bathing your dog in a mixture of 2 cups of water and a lemon or lime sliced thinly also helps keep off fleas and, like the eucalyptus leaves, smells good.
Parkinson's disease (PD) is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. The symptoms generally come on slowly over time. Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking.
By studying families with hereditary Parkinson's disease, scientists have identified several genes that are associated with the disorder. Studying these genes helps understand the cause of Parkinson's disease and may lead to new therapies.So far, five genes have been identified that are definitively associated with Parkinson's disease. 1  SNCA (synuclein, alpha non A4 component of amyloid precursor): SNCA makes the protein alpha-synuclein. In brain cells of individuals with Parkinson's disease, this protein aggregates in clumps called Lewy bodies. 2  Mutations in the SNCA gene are found in early-onset Parkinson's disease. 3  PARK2 (Parkinson's disease autosomal recessive, juvenile 2): The PARK2 gene makes the protein parkin.
