The final histopathologic examination revealed the same high grade papillary urothelial carcinoma with malpighian
differentiation, and the surgical oncological margins were free of tumor.
In all species the appendices of the midgut were tracheated and extended deep into the posterior end of the insect, terminating blindly in the hemolymph similarly to the primary Malpighian
tubules, in contrast to Savage (1962).
Ultraestructural investigation of the spore-forming protist Nephridiophaga blatellae in the Malpighian
tubules of the German cockroach Blatella germanica.
The frequency of Malpighian
tubule nuclear phenotypes in specimens subjected to infection by T.
On the structure and use of the malpighian
bodies of the kidney, with observations on the circulation through that gland.
Many holometabolous insects exhibit similar behavior, but neuropterans are unusual because their silk is produced by Malpighian
tubules (excretory organs) and spun from the anus.
to identify the materials passing through a spider's anus, since the majority of this material consists of the products of post-assimilatory metabolic processes from the Malpighian
tubules, rather than undigested matter.
Microscopically only 2 of 32 spleens examined showed degeneration or necrosis; pyknosis and karyorrhexis of lymphocytes in some corpuscles was observed in one and slight necrosis of the malpighian
follicle in the other (Pant & Vijayaraghavan).
What we observed was quite intriguing: in Celera, Cyp6g1 was expressed in the midgut, the Malpighian
tubules and the fat body, the tissues 'traditionally' associated with the detoxification of xenobiotics.
Once inside the insect, the fungi develop as hyphal bodies that disseminate through the haemocele and invade diverse muscle tissues, fatty bodies, Malpighian
tubes, mitochondria and haemocytes, leading to death of the insect 3 to 14 days after infection.
Native polyacrylamide gel electrophoresis with [alpha]- and [beta]-naphthyl acetate as substrates revealed six general esterase isozymes (Esterase 1-6) in whole body homogenates of larvae, pupae, and adults and tissue extracts (alimentary canal, fat body, Malpighian
tubules, and salivary glands) of T.
Temperature-shocked larvae (positive controls) showed a maximum [beta]-galactosidase activity in all the tissues except Malpighian
tubules (Figure 2B).
