Histology and ultramorphology of the mesenteric sacs in the Neotropical termite Neocapritermes opacus (Blattaria, Termitidae, Termitinae)
(2020-03-01)
Neocapritermes opacus is a Neotropical termite, which feeds on a variety of food sources, including highly decayed wood and humus. Similar to many Termitidae, this species contains a mixed segment in the intestine, an ...
Ultrastructural study of the salivary glands of the sugarcane spittlebug Mahanarva fimbriolata (Stal, 1854) (Euhemiptera : Cercopidae)
(Elsevier B.V., 2006-01-01)
Spittlebugs are insects that suck sap from plants and regurgitate saliva containing toxic enzymes into the leaves. As a consequence, the conductive channels are blocked resulting in dry leaves, thus giving a burned aspect ...
Ultrastructural observations on the foliar secretory cavities of Porophyllum lanceolatum DC. (Asteraceae)
(Urban & Fischer VerlagJenaAlemanha, 1999)
Características regionais sobre a ultra-estrutura das células principais do epitélio do ducto epididimal de Agouti paca
(2009-01-01)
The principal (P) cells of epididymidis surface epithelium of Agouti paca were related to processes of adsorptive endocvtosis and phase-fluid endocvtosis, as well as protein secretion apparently also occur. These findings ...

Development and comparative morphology of the reproductive system in different aged males of the drywood termite Cryptotermes brevis (Blattaria, Isoptera, Kalotermitidae)
(2019-01-01)
Termites are eusocial cockroaches, which have received great attention due to their diversity of reproductive strategies. Although these novelties allow new interpretations concerning the mating biology of these insects, ...
Drosophila Atlastin in motor neurons is required for locomotion and presynaptic function
(Company of Biologists Ltd., 2017)
Hereditary spastic paraplegias (HSPs) are characterized by spasticity and weakness of the lower limbs, resulting from length-dependent axonopathy of the corticospinal tracts. In humans, the HSP-related atlastin genes ...
Ultrastructure and cytochemistry of the pearl gland in Piper regnellii (Piperaceae)
(Nordic Journal of Botany, 2014)
The immunophilin Zonda controls regulated exocytosis in endocrine and exocrine tissues
(Wiley Blackwell Publishing, Inc, 2021-01)
Exocytosis is a fundamental process in physiology, that ensures communication between cells, organs and even organisms. Hormones, neuropeptides and antibodies, among other cargoes are packed in exocytic vesicles that need ...
A glycoproteinaceous secretion in the seminal vesicles of the termite coptotermes gestroi (Isoptera: Rhinotermitidae)
(2019-12-01)
Coptotermes gestroi is a subterranean termite with colonies generally headed by a pair of primary reproductives, although neotenics may occur. In this study, the male reproductive system was compared during different life ...
