Structure and function of defensive glands in soldiers of Glossotermes oculatus (Isoptera: Serritermitidae)
The soldier caste represents the most conspicuous realization of termite eusociality, characterized by an extreme anatomical, behavioural, and physiological specialization. Numerous strategies haveExpand
The frontal gland in workers of Neotropical soldierless termites
The presence of the frontal gland is well established in termite soldiers of Rhinotermitidae, Serritermitidae, and Termitidae. It is one of their main defensive adaptations or even an exclusiveExpand
Iron-ascorbate cleavable malic enzyme from hydrogenosomes of Trichomonas vaginalis: purification and characterization.
Two isoforms of NAD(P)(+)-dependent malic enzyme (EC were isolated from hydrogenosomes of Trichomonas vaginalis. A positively charged isoform at pH 7 was obtained in a single purificationExpand
Ultrastructure of the digestive tract in Acarus siro (Acari: Acaridida)
The gut of the mite Acarus siro is characterized on the ultrastructural level. It consists of the foregut (pharynx, esophagus), midgut (ventriculus, caeca, colon, intercolon, postcolonic diverticula,Expand
New magnetically responsive yeast-based biosorbent for the efficient removal of water-soluble dyes
Abstract Fodder yeast ( Kluyveromyces fragilis ) cells were magnetically modified by a contact with the water-based magnetic fluid in order to prepare a new type of magnetically responsiveExpand
Fat body of Prorhinotermes simplex (Isoptera: Rhinotermitidae): ultrastructure, inter-caste differences and lipid composition.
Ultrastructure of the fat body was studied in following castes and developmental stages of Prorhinotermes simplex: larvae of the first and the second instar, pseudergates, presoldiers, soldiers,Expand
The all–or–none rule in morphogenetic action of juvenile hormone on insect epidermal cells
We have investigated ultrastructural changes in the integuments of larval–adult and larval–pupal intermediates produced by exogenous application of juvenile hormone (JH) analogues in PyrrhocorisExpand
Ultrastructural ontogeny of the labial gland apparatus in termite Prorhinotermes simplex (Isoptera, Rhinotermitidae).
The labial glands in Prorhinotermes simplex consist of secretory cells organized into acini, water sacs and the ducts connecting the gland parts to the basis of the labium. Acini are composed ofExpand
