Cancer in terms of its origin was still a mystery. It has multiple etiologic factors, including ineffectiveness of immunologic surveillance. The distribution of human cancers points to a progressive accumulation of somatic genetic error. Sir Macfarlane Burnet has made immense contributions in the field of cancer surveillance. This paper analyses how the old masters were watching out for the hid...

Among the ambassadors of Romanian science and culture, we include the doctor Vintilă Ciocâlteu. Along with Victor Babeş, Nicolae Paulescu and George Emil Palade, Vintilă Ciocâlteu contributed further, by the reagent which he prepared together with Otto Folin, to the completion and deepening of the knowledge of cell biology within the medical agricultural, horticultural research or industrial ch...

Builder (23 Jan. 1864), the editor George Godwin was able to assert, "Never was change more complete than that which has occurred in hospital building since we initiated in these pages the movement against the defective plans in use, and showed the advantages of the pavilion system of arrangement now univerally adopted".

The title compound, C(26)H(20)N(2), first reported in 1891, was obtained as a by-product in the preparation of benzildianil from benzil and excess aniline. The dihedral angles between the fused benzene ring and the pendant phenyl rings are 17.93 (11), 53.18 (10) and 89.08 (12)°.

Here we summarize the works of the Hungarian mathematician Jenő Egerváry (1891–1958) on the trinomial equations. We present some of his ideas and methods with examples. Some earlier results in the history of mathematics in Hungary about the trinomial equations are also discussed.

Several hormonal and other factors have been proposed to be involved in the initiation of parturition. However, definitive sequential events leading to initiation of parturition are still lacking. Conceptual evolution on the mechanism of initiation of parturition since 1891 has been briefed.

Parabatinga danielae sp. n. is described and illustrated based on material collected in caves of the Carajás region, state Pará, Brazilian Amazonia. With inclusion second species genus, we propose here a new diagnosis for its type species, P. brevipes (Keyserling, 1891).

The second volume, containing only the illustrations and legends, is a thing of beauty, because of the superb histologic techniques developed in Klatskin's laboratory and the splendid color reproductions by the publishers. The work was worth waiting for. It will not go out of date. Hepatic histopathology as revealed by the light microscope will not change. Of course new concepts, new techniques...
