She was referred to the hematologist who performed a myelogram that showed neutrophils maturation arrest, polymorphonuclear decrease, no evidence of significant myelodysplasia and no cytological evidence of pathological infiltrates (Figure 1).
Pathological examinations of the testicular biopsy specimens revealed hypospermatogenesis, maturation arrest and germ cell aplasia in 34.4%, 31.2% and 34.4% of patients, respectively.
17 Histopathological variations were observed in different AZF region deletions like Sertoli Cell Only Syndrome associated with AZFa region deletion while AZFb region was associated with maturation arrest in meiosis and AZFc microdeletion was found in hyposper matogenesis.
IVM was studied in patients with repeated oocyte maturation problems from Empty Follicle syndrome (EFS) to oocyte maturation arrest. Patients with Genuine-EFS syndrome (G-EFS) benefited from IVM cycles and achieved ongoing pregnancies (25).
Severe congenital neutropenia appeared unlikely as the bone marrow did not show 'maturation arrest' at the myelocyte stage of development, the promyelocytes were not increased nor showed dysplastic morphology such as large size, atypical nuclei or vacuolated cytoplasm.
33) patients had dysmyelopoeisis which included abnormal shaped nuclei, folded, cleaved nuclei, giant metamyelocyte, myelocyte, pseudo pelger heut anomaly, vacuolisation of the cells and maturation arrest. 6(22.
The ESX-1 system modulates the host defence through different ways like phagosome maturation arrest, inhibition of TLR signalling in macrophages, macrophage apoptosis induction, and interaction with laminin.The here proposed project forms part of a multidisciplinary anti-virulence drug discovery program focusing on the identification of important host cell signalling pathways that are involved in the pathogenesis, entry and intracellular survival of M.tb.

A: In one of our studies, we determined the reproductive hormones and morphological changes induced by mobile phone radiation and found that long-term exposure to mobile phone radiation leads to reduction in serum testosterone levels and cause hypospermatogenesis and maturation arrest in the spermatozoa in the testis of albino rats.
