(32)P-labelled phosphoglucomutase was digested with trypsin after denaturation and two peptides were isolated that contained the bulk of the radioactivity bound to peptides. Both peptides appeared to derive from an identical section of the molecule. Peptic and subtilisin digests of the tryptic peptides were prepared. The resulting radioactive peptides were purified and their sequences studied. ...

The association between thyroid autoimmunity and thyroid cancer was carried out in a series of solitary thyroid nodules submitted to fine-needle aspiration cytology and subsequent histopathology. US guided FNACs were obtained from 295 unselected consecutive patients with single thyroid nodules and positive (98) or negative (197) serum anti-thyroid antibody. Cytological results were classified i...

BACKGROUND Influenza viruses cause serious infections that can be prevented or treated using vaccines or antiviral agents, respectively. While vaccines are effective, they have a number of limitations, and influenza strains resistant to currently available anti-influenza drugs are increasingly isolated. This necessitates the exploration of novel anti-influenza therapies. METHODOLOGY/PRINCIPAL...

OBJECTIVE To evaluate clinical characteristics and outcomes in incidentally detected lung cancer and in symptomatic lung cancer. MATERIAL AND METHODS We designed a retrospective study including all patients undergoing pulmonary resection with a curative intention for NSCLC. They were classified into two groups according to the presence or absence of cancer-related symptoms at diagnosis in asy...

A peptide was obtained from culture filtrates of a bacterium which was newly isolated and tentatively named Bacillus cereus SW. The peptide was composed of Asx, Ser, Glx, Leu, Tyr, Pro, and an unknown amino acid in a ratio of 2:1:1:1:1:1:1, but, unless hydrolyzed with HCI, it was ninhydrin reaction negative. The peptide effectively inhibited the growth of all fungi and yeasts so far examined, w...
