Background Emerging evidence supports the view that (AQP) aquaporin water channels are
regulators of transcellular water flow. Consistent with their expression in most tissues, AQPs …

There are two main classes of hormones in insects: 1) the true hormones produced by
epithelial glands and belonging to the ecdysteroids or juvenile hormones and 2) the …

Brain primary tumors are among the most diverse and complex human cancers, and they
are normally classified on the basis of the cell-type and/or the grade of malignancy (the most …

Publisher Summary Selective reabsorption is responsible for regulatory changes in hindguts
of most terrestrial insects; salt-water species experience the different problem of eliminating …

Background Cold tolerance is a key determinant of temperate insect distribution and
performance. Chill-susceptible insects lose ion and water homeostasis during cold …

Chill susceptible insects suffer tissue damage and die at low temperatures. The mechanisms
that cause chilling injury are not well understood but a growing body of evidence suggests …

Ammonia, an end product from amino acid and nucleic acid metabolism, is highly toxic for
most animals. This review will provide an update on nitrogen metabolism in terrestrial and …

Arthropods have integrated digestive and renal systems, which function to acquire and
maintain homeostatically the substances they require for survival. The cryptonephridial …

Cold-acclimated insects maintain ion and water balance in the cold, potentially by reducing
permeability or increasing diffusion distance across ionoregulatory epithelia such as the …

Much of our understanding of the ionoregulatory and excretory physiology of blood-feeding
insects can be traced to a series of papers by Simon Maddrell and colleagues in the 1970s …
