Idiopathic Parkinson’s disease (PD) is an age-dependent, neurodegenerative disorder and is predominantly sporadic. Only 20–30% of patients have a positive family history for PD with a complex mode of inheritance. In a few extended families, the disease is inherited as an autosomal dominant trait. Linkage to chromosome 4 was reported in a large Italian kindred multiply affected by an early-onset form of PD (1). However, this finding was not...

In routine histopathology, most tissues are fixed in formalin and embedded in paraffin for long-term preservation. DNA can be extracted from these tissues for subsequent molecular analysis by amplification methods. We describe herein a protocol for DNA preparation from paraffin-embedded tissues based on published procedures (1–3). In brief, tissue sections are placed into microfuge tubes, then deparaffinized with xylene. The xylene is...

The list of individuals who contributed to the development of EFT can never be complete because most of them lived over 5,000 years ago. Those are the brilliant physicians who discovered and mapped the centerpiece of EFT, namely, the subtle energies that course through our bodies. These subtle energies are also the centerpiece of acupuncture and, as a result, EFT and acupuncture are cousins. Both disciplines are growing rapidly here in the...

Wetlands are the ecotonal or transitional zones between terrestrial and aquatic ecosystems where the water table is usually at or near the surface of the land, which is covered by the shallow water (Mitsch & Gosselink, 1986). Due to these characteristics, wetlands provide opportunities for adaptations to different plant and animal species with high diversity of life-forms. Thus wetlands are among the most biologically diverse and...
