Abstract:
... Workers, queens and males of all examined Discothyrea species of the ‘sauteri group’, that have laterally expanded frontal lobes and well-developed antennal scrobes, are characterized by two hairy areas on the outer surface of their procoxae. Histological and ultrastructural examination of Discothyrea sauterirevealed that each of these areas is associated with a novel exocrine gland: the proximal ...

Abstract:
... We collected a queenright colony of the very rare Myopias conicara Xu in Vietnam (1 dealate queen, 41 workers and 38 larvae). Both the queen and workers fed on xystodesmid millipedes. After paralyzing a millipede, its head was first removed by the workers, and then the larvae were put on the opening of the collum (anteriormost ring of the trunk). After the inner tissue of the collum was consumed, ...

Abstract:
... It is a commonly known fact that all ground beetles possess abdominal pygidial glands with relatively similar gross structure and function among species. Still, morphology of the glands and composition of their secretions have not been studied in most ground beetle species. These exocrine glands and their products are mainly associated with defence in natural environments. In this paper, we studie ...

The gland is divided into two secretory regions located just behind the mouth, on the dorsal and ventral side of the pharynx, respectively. The dominant s ...

In this study, we examined the rooibos extract for active components in vitro and monitored its fast-acting effects against dryness in humans. Our in vitro analysis demonstrated that the M3R-stimulating effect of rooibos extract was similar to that of eriod ...

Abstract:
... Plethodontid salamander courtship is an elaborate yet conserved set of behaviors that involve many different sensory signals. Exocrine glands in the skin produce pheromones that facilitate courtship. These glands, known as courtship glands, are described as being sexually dimorphic, only present in males. Thus, we were surprised to discover glands in female Desmognathus brimleyorum that are histoc ...

Abstract:

In most species, including those with the simplest socia ...

To identify putative transporters involved ...
