Since its inception in 1898 the American Journal of Physiology has been a leader in diabetes research and has published many key articles on the subject. The Journal first published studies of phlorhizin-induced diabetes in 1898, and after many other contributions went on to publish the first reports of Banting, Best, Macleod, and Collip in 1922 concerning the isolation and purification of insu...

The crisis of the Spanish Catholic monarchy paved the way for the creation of more than twenty republics in Latin America between 1810 and 1825. This paper analyzes early nineteenth-century Spanish American republican experiences, which have been generally neglected in the historiography, as constitutive parts of Atlantic republicanism. It focuses on the theologico-political considerations of t...

BACKGROUND The records of genus Bubopsis McLachlan, 1898 with species Bubopsis tancrei Weele, 1908 and the genus Nousera Navás, 1923 with species Nousera gibba Navás, 1923 have not been published in China. NEW INFORMATION The genus Bubopsis McLachlan, 1898 with species Bubopsis tancrei Weele, 1908 and the genus Nousera Navás, 1923 with species Nousera gibba Navás, 1923 are recorded for the fi...

In this paper some helicoid species from eastern Algeria are investigated using a morphological and molecular approach. The investigation of the genital organs of M. massylaea (Morelet, 1851), the type species of the genus Massylaea Möllendorff, 1898, showed the same autapomorphic character states as are considered typical for Eobania P. Hesse, 1913. These findings are fully supported by the ge...

The Afrotropical dark sac spider genus Messapus Simon, 1898 (Corinnidae: Corinninae) currently only comprises two described species, the type species M. martini Simon, 1898 and M. natalis (Pocock, 1898), which have both recently been redescribed. The leg and setal morphology of Messapus is studied using scanning electron microscopy for the first time, for M. martini and M. tigris sp. n., and ad...

body fluids (Evans, 1993) is reflected in their eggs (Davenport et al., 1981; Riis-Vestergaard, 1982; Watanabe and Kuo, 1986; Mangor-Jensen, 1987; LaFleur and Thomas, 1991). However, these eggs have none of the advantages of the adult osmoregulatory organs associated with homeostasis, and the typical drinking activity seems to start at, or shortly before, hatching (Guggino, 1980; Mangor-Jensen ...
