Guloheptonic acids and alpha-d-alpha-guloheptose

The comparison of alpha power, peak alpha frequency, frontal alpha asymmetry between irritable bowel syndrome and healthy people

Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder that is characterized by abdominal pain or discomfort and changed intestinal habits. The aim of This study was the comparison of features of brain oscillations in alpha frequency band by using rest-electroencephalography (EEG) between patients with IBS and healthy control. 11 IBS patients (7 female and 4 male) and ...

Antigenicity of Polypeptides (poly Alpha Amino Acids)

It has been shown that the polymers GLA5, GLT, GLA40, and GLAT are antigenic in human beings. Both immediate skin reactions and delayed (cellular) reactions were observed. The antibody produced reacted well in the precipitin reaction, agglutinated antigen coated tanned sheep cells, was less effective in inducing PCA reactions, and failed to sensitize guinea pigs for passive systemic anaphylaxis...

One Pot Synthesis of Alpha-Aminonitrile and Alpha-Amino Acid From Schiff Bases

Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.
