The patients with ASU who progressed toward CSU were characterized by a positive ASST result, thyroid autoimmunity, and profound basopenia at baseline.
In spite of the difference in clinical outcome, the gene expression pattern in children and adults with ALL is very similar and is primarily dependent on immunophenotype and cytogenetic aberrations. However, when age groups are compared, the expression patterns of infants and adults over 40 show a remarkable similarity.
Рассеянный склероз (РС) является хроническим воспалительным демиелинизирующим за-болеванием ЦНС, которое ввиду своей распространенности (50 случаев на 100 тыс. населения) и преимущественным поражением лиц трудоспособного возраста имеет важное медикосоциальное значение. На сегодняшний день РС представляется мультифакториальным заболеванием, ведущим патогенетическим механизмом которого, лежащим в основе воспаления, является аутоиммунный процесс. Многочисленные доказательства аутоиммунной природы РС получены в серии экспериментальных и клинических работ.
Introduction. The main features of bone marrow blasts cells in Burkitt lymphoma/leukemia (BL) are L3 morphology, mature immunophenotype of blasts with surface IgM expression, and presence of typical MYC gene rearrangements.The aim of the study was to show discrepancy examples in laboratory signs of BL.Patients and methods. 10 patients (8 boys and 2 girls) aged 1 to 18 years were included in the present study. The inclusion criterion was the identification of discrepancies between flow cytometric, morphological and cytogenetic data.Results. In 2 cases there were no rearrangements of the MYC gene. In 2 patients, the L2 morphological variant went against the presence of typical MYC gene rearrangements. In one case, undifferentiated blasts cells were described by morphology together with presence of surface IgM, and atypical genetics. In 8 patients, there was no expression of surface IgM. Of these, patients with absence of cytomorphological data cytometric and genetic data were controversial.Сonclusion. The cases presented in this study and the cases described in the literature demonstrate the importance of an attentive and comprehensive approach in evaluating the results of laboratory tests in the diagnosis of BL.
The early verifying of cerebral ’s gliomas progression is an actual problem. It was found that the level of mircroRNA-21 expression is a highly specific in a tumor’s evolutional process. That the aim of the study was the assessment with level of mircroRNA-21 expression in blood and saliva of patients with cerebral glioma progression and patients without it which were verified by PET using [ 11C] methionine. It was found that in majority of cases, the negative dynamics of cerebral neoplastic lesions coincided with an increase in metabolic changes in the residual glioma and highly correlated with the level of mircroRNA-21 expression. This allows us to consider a highly significant the level of mircroRNA-21 expression as a screening technique in monitoring the evolution of the tumor process and the effectiveness of the treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
