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.

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.
