Abstract: Described is a method for diagnosing a person having or being at risk of developing certain B-cell pathologies, including Sjögren's Syndrome and non-Hodgkin's lymphoma, and excluding patients with symptoms similar to Sjögren's Syndrome but with a different etiology, comprising the following steps: providing a sample of a body fluid or tissue from said person, said sample containing a mixture of unknown proteins, protein fragments or peptides; analyzing said samples with mass spectrometry to generate a m/z (mass to charge ratio) spectrogram for each sample; comparing whether the patient's sample contains m/z values that are characteristic of a Sjögren's Syndrome reference database derived from the analysis and cataloguing of multiple patient spectrograms; and determining whether said patient either has or does not have Sjögren's Syndrome on the basis of this comparative analysis.

Abstract: The new art to which this application pertains is an electrically operated boom, of various overall lengths, to extend a small rotary blade electric grass cutter from a nominal 5 to 20 feet down, or out, to cut grass on steep slopes and in ditches. It is a fully mechanized electric grass cutting machine for cutting grass where it is difficult, impossible, or unsafe to stand up. It is an electric, rotary blade, grass cutting-head on the end of a three-section electrically powered telescoping boom, mounted on a powered carrier vehicle; such as, a small riding mower. The carrier vehicle is not a part of this application. It can be operated by persons of limited strength, physical abilities or aptitudes. It is controlled with two electric switches and one hand crank. Complete machine and carrier are inexpensive; less than the cost of a small riding mower. It is a machine for average people who are not skilled in machine operation; and for residential use.
