Background: This study was carried out to determine the frequency of CD34 positivity in acute lymphoblastic leukaemia (B-ALL) in our population and to report its association with the clinicopathological profile at the time of diagnosis.
Methods: The cross-sectional study was conducted at National Institute of Blood Diseases and Bone Marrow Transplantation, Karachi, Pakistan, from March 2020 till December 2020.Newly diagnosed patients were selected, from both genders and all age groups. Relevant history and findings of physical examination were recorded. Immunohistochemistry was done on trephine biopsy and molecular studies were carried on bone marrow aspirates or peripheral blood samples.
Results: Out of 105 patients enrolled, 67 (63.8%) were males, with a male to female ratio (M: F) 1.8:1. Of the total patients, 62 (59.04%) were above 15 years of age. CD34 was expressed in 73 (69.5%) cases. Lymphadenopathy, splenomegaly, and hepatomegaly were separately noted in context to CD 34 expression in 22 (66.6%), 24 (64.8%), and 14 (58.3%) patients, respectively. CNS disease was seen in a total of 3(2.75%) subjects, in which 2 (66.6%) of the patients had CD34 expression. Total 81 patients in our study fall into the high-risk group out of which CD 34 expression was seen in 58(71.6%) subjects. Cytogenetic analysis, BCR-ABL p190, and MLL gene rearrangement were investigated in all participants. Cytogenetic analysis revealed an abnormality in 20 (19%) cases out of which 13 (17.8%) cases were from CD34 positive group.
Conclusion: Our study reported CD34 expression in more than two-thirds of cases. High-risk disease was significantly associated with CD34 expression.

Our study intended to explore Hesp antioxidant and anti-inflammatory effects against TAA hepatic fibrosis in rats. Hesperidin (Hesp), is a pharmacologically active flavonoid, found abundantly in citrus species. Our present research attempts to inspect the potential hepatoprotective role of Hesp against thioacetamide (TAA)-induced hepatic fibrosis.

: Human fetal liver hematopoietic stem cells have proven potential as therapeutics but lack extensive research due to their limited supply. Even expanded fetal liver hematopoietic stem cells enter senescence or lose their self-renewal capacity after a few days in culture. The present study aimed to obtain a homogeneous and persistent supply of hematopoietic stem cells from the fetal liver by establishing a cell line through immortalization of cells by enhancing telomerase activity.

A 9-year-old male castrated golden retriever cross was evaluated for an acute onset of ataxia. A complete blood count revealed marked leukocytosis, anemia, and thrombocytopenia. Leukocytosis was characterized by marked lymphocytosis, monocytosis, neutropenia, and eosinopenia.

Leukemia stem cells (LSCs), capable of simultaneous self-renewal and differentiation, are resistant to chemotherapy and the cause of relapse in refractory cases of leukemia. As a method to rapidly generate LSCs has not been established, research on LSCs as therapeutic targets has been hampered. Here, we demonstrate that K562 leukemia cells acquired LSC properties with increase in stemness markers such as CD34, Oct3/4, and Nanog and metabolic alterations towards OXPHOS by culturing cells on synthetic polymer hydrogels.

Background/objectives: Tissue remodeling, including dense eosinophil infiltration, is essential for forming inflammatory nasal polyps (NPs) and the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). Toxic eosinophil major basic protein (MBP) damages the sinus mucosa epithelium and lamina propria, which initiates reparative processes leading to tissue remodeling. MBP specifically binds to BMK-13 antibodies allowing immunohistochemical (IHC) tissue staining for eosinophils.
