Mammalian neural stem cells generate transit amplifying progenitors that expand the neuronal population, but these type of progenitors have not been studied in Drosophila. The Drosophila larval brain contains approximately 100 neural stem cells (neuroblasts) per brain lobe, which are thought to bud off smaller ganglion mother cells (GMCs) that each produce two post-mitotic neurons. Here, we use...

Renal lesions commonly seen in SBE include localized infarcts, abscesses, therapy-related interstitial nephritis, and glomerulonephritis ( 1-2). The incidence of glomerulonephritis associated with SBEhas not been determined. The most commonorganisms leading to SBEare the streptococcus viridans group and coagulase-negative staphylococci, including Staphylococcus (Staph.) epidermidis ( 1). The re...

a position to use their microscopes. I have read with much interest Lieut.-Col. O. A. R. Berkeley-Hill's article in your issue for last May, and have been struck with the fact that subtertian crescents were found in the blood films from five patients who were inoculated with the blood of persons suffering from benign tertian malaria. At first sight this evidence appears quite a formidable argum...

Spontaneous crescentic glomerulonephritis (CrGN) in animals has only been reported in dog and sheep. We report the pathological features of CrGN in a 17-year-old male polar bear that died due to renal failure. Histologically, the lesions were characterized by fibrocellular crescents, adhesion between Bowman's capsule and the glomerular capillary tuft and an increase in the mesangial matrix in g...

A new species of the spider Hasarius adansoni sp.nov, was described for first time in Iraq which are collected from Baghdad Dora city .This is a genus jumping spiders have eight eyes with long legs covered spines and hair male black color white crescents their body crescent present on back part head, another one front opisthosoma pedipalps that partly two small dots posterior even smaller ones ...

Case 1.-A 77-year-old woman was admitted complaining that her left calf had been swollen for three weeks. The left lower leg was 4 cm greater in circumference than the right and the calf was moderately tender with a trace of pitting oedema at the ankle. An ascending venogram showed nothing abnormal, but in spite of this the patient was treated with heparin. Twelve hours later the calf had incre...
