Conventional transmission electron microscopy of 1-1 haptoglobin isolated molecules and paracrystalline aggregates.
Data are presented relating conventional transmission electron microscope (CTEM) ultrastructural observations of the monomeric phenotypic variant (Hp 1-1) of the haptoglobin class of blood glycoproteins. Through comparison of these findings with homologous published data, obtained by means of scanning transmission electron microscopy (STEM), the validity of CTEM in molecule shape and fine structure determination is confirmed. An experimental procedure for Hp 1-1 crystallization is also reported.
Electron microscope observations on the substructure of T-even (T2, T4) head.
New preparative methods have been devised which allow electron microscope observation of T-even head substructure, under conditions of negative staining. Capsomeric constitution of the head shell could so be confirmed and demonstrated for T2 and T4. In addition capsomere size and shell thickness of the head of both phages have been determined and the structural organization of the DNA inside T4 head revealed.

[Diagnostic and oncologic updating on gallbladder papilloma. Personal experience and review of the literature].
After a correct definition of the pathologic meaning of "papilloma of gallbladder" and the considerations about the main epidemiologic, pathogenetic and diagnostic guidelines, the authors discuss the meaning of the apparent higher frequency of this pathology in the biliary tract than in the gallbladder localization. This condition probably derives from the precocious appearance of pain or jaundice during choledocal pathology respects to the asymptomatic gallbladder localization. Moreover, using morphological indicators of intracholecistic ultrasonography, the gallbladder's polypoid lesions are divided in group s and for each of the m are indicate d most/actual curative criteria. Currently tendency is to check periodically gallbladder polypoid lesions, and to recure to surgery when the lesion result large more than 1 cm, single, associated with stones, when the patient is older than 50 years and when there is a clear clinical symptomatology. Finally, the authors discuss the malignance evolution of these lesions attaching importance as prognostic role to the study of the K-ras and p-53 proto-oncogenes, because they consider the carcinogenesis like a "multi-step" evolution.
