a) Female mitotic metaphase; (b) male mitotic metaphase; (c) female pachytene complement with a WZ bivalent identified according to W-chromosome heterochromatin; (d) male pachytene complement; (e) a highly polyploid female nucleus of Malpighian tubule
cells with a large sex chromatin body; (f) a male nucleus of Malpighian tubule
cells without W chromatin.
In all cases the appendix tubules are one-third the diameter of the Malpighian tubules and motile: in Euphasmatodea they are coiled like springs, and contract and expand throughout the body cavity (Shelomi & Kimsey 2014).
The increased acidity at the midgut/hindgut junction is due to the influx of uric acid from the Malpighian tubules.
Ultraestructural investigation of the spore-forming protist Nephridiophaga blatellae in the Malpighian tubules of the German cockroach Blatella germanica.
Two new species of Nephridiophaga (Zygomycota) in the Malpighian tubules of cockroaches.
Malpighian tubules were fixed in an absolute ethanol: acetic acid solution (3:1, v/v) for 1 minute, rinsed in 70% ethanol for 5 minutes and subjected to the Feulgen reaction with acid hydrolysis in 4 M HCl at 25[degrees]C for 65 minutes (Mello, 1997; Garcia et al.
Not only nuclei with the normal phenotype, but also nuclei with heterochromatin decondensation or showing necrotic and apoptotic characteristics were observed in the Malpighian tubules of P.
To our surprise, we saw the same tissues--the midgut, Malpighian tubules
and fat body--light up in bright green fluorescence.
were not found to induce hsp70 against the effluent used in the present study.
Testes length (TL), testes area (TA), malpighian tubules
length (MTL), and malpighian tubules
area (MTA) were measured as shown in Figure 1.
More specifically, the expression level in midgut was 8- and 4- fold higher than that in Malpighian tubules
and fat body, respectively.
Scanning electron microscope observations on the pathological changes of Malpighian tubules
in the worker honeybee, Apis mellifera, infected by Malpighamoeba mellificae.
1994) and crustaceans (Onken and Putzenlechner, 1995), and in insect Malpighian tubules
(Al-Fifi et al.
The digestive tracts were divided into the foregut, midgut, ileum, rectum, and Malpighian tubules
This pathogen primarily infects the Malpighian tubules
but often spreads systemically (Andreadis & Hanula 1987).
