a-The epidermis showed improved appearance after Er:YAG laser as the keratinocytes become well organized and malpighian layer thickness had increased together with thinning in the stratum corneum.
Incisional biopsy was done which showed skin with focal hyperkeratosis and crusting on the epidermal surface, keratinocytes of the Malpighian layer showed nucleomegaly and loss of polarity.
With respect to its histopathology, cholesteatoma was defined as "containing layers of keratin in a cavity lined by squamous epithelium and subepithelial connective tissue" [19], "development of a Malpighian epithelium" [3], lesion "formed from keratinizing stratified squamous epithelium, the matrix of which comprises epithelium that rests on a stroma with varying thickness and is called the perimatrix" [8].
To validate the expression of MAG-specific genes, different tagmata and tissues including head (5 males), thorax (5 males), abdomen (5 males), midgut (20 males), fat body (50 males), Malpighian tubules (50 males), testis (50 males), and MAG/ED (100 males) were cut off or dissected from 3-d-old adult B.
A cystoscopic examination with TUR biopsy of the neobladder was performed, showing a malpighian urothelial metaplasia.
When the larval fat body, midgut, and Malpighian tubules are exposed to low temperatures (-10 [degrees]C or -20 [degrees]C), viability of the tissues is slightly reduced.
Six larvae from each group were dissected to collect fat body, midgut, hemocytes, malpighian tubule and epidermis at different time points after injection, respectively.
The undifferentiated hindgut starts within the 4th or 5th abdominal segment, marked by the origin of the Malpighian tubules.
The first smear cytology revealed adipose tissue with a relatively normal aspect and the second showed a malpighian keratinized multilayered epithelium.
One theory holds that uric acid in fat body is transported via the Malpighian tubules to the hindgut, where it undergoes anaerobic digestion by uricolytic bacteria (Breznak 2000).
Female mosquitoes rely on their kidneys (called Malpighian tubules) when consuming a human blood meal.
