Effect of extremely low frequency weak magnetic fields

Project description:We used AML12 cells exposured with pulsed extremely low frequency weak magnetic fields for 4 msec at increasing frequency of 1, 2, 3, 4, 5, 6, 7, and 8 Hz for 1 sec each. The 1-to-8 Hz pulses over 8 sec were repeated indefinitely. Peak magnetic intensity was 100 mG. AML12 cells were incubated for 1 h under extremely low frequency weak magnetic fields.

Proteomic Identification of Cereal Grains Associated with Archaeological Artefacts

Project description:The domestication and transmission of cereals is one of the most fundamental components of early farming, but direct evidence of their use in early culinary practices and economies has remained frustratingly elusive. Using analysis of a well-preserved Early Bronze Age wooden container from Switzerland, we propose novel criterial for the identification of cereal residues. Using gas chromatography mass spectrometry (GC-MS), we identified compounds typically associated with plant products, including a series of phenolic lipids (alkylresorcinols) found only at appreciable concentration in wheat and rye bran. The value of these lipids as cereal grain biomarkers were independently corroborated by the presence of macrobotanical remains embedded in the deposit, and wheat and rye endosperm peptides extracted from residue. These findings demonstrate the utility of a lipid-based biomarker for wheat and rye bran and offer a methodological template for future investigations of wider range of archaeological contexts. Alkylresorcinols provide a new tool for residue analysis which can help explore spread and exploitation of cereal grains, a economically fundamental component the advent and spread of farming.
