It is generally accepted that acute myelogenous leukemia (AML) patients are immunocompromized. On the other hand, antileukemic immune reactivity is important for the improved survival of AML patients treated with allogeneic stem cell transplantation and antileukemic immunotherapy is also considered for patients treated with conventional chemotherapy. In this article, we review the available stu...

Nuclear ionic channels (NICs) represent ubiquitous structures of living cells, although little is known about their functional properties and encoding genes. To characterize NICs, liver nuclear membrane vesicles were reconstituted into either planar lipid bilayers or proteoliposomes. Reconstitution of nuclear envelope (NE) vesicles into planar lipid bilayer proceeded with low efficiency. NE ves...

Eggs of Ambystoma maculatum in early stages of development were separated into two groups and maintained at 5 and 14 °C, respectively. In one series of animals comprising both temperature groups, the right otic vesicle was extirpated at stage 27. In another series the right forelimb disc was extirpated at stage 30. Following operation, animals of both groups were kept at 18 °C. Frequency and ex...

Background: Cutaneous findings in the setting of HIV infection encompass a broad spectrum of diseases. Only few cases of vitiligo or alopecia areata have been described in HIV/AIDS patients and it remains unclear whether there is a causal relationship between HIV/AIDS and these two conditions. Observations: Our patient initially presented with diffuse generalized pruritic hypoand depigmented ma...

site-specific T-lymphocytes release high levels of gamma interferon, which is required to activate and synergize macrophages for toxoplasmacidal activity.5 Therefore, delayed immune reconstitution after transplantation puts patients at risk of reactivation of latent infection. The precise kinetics of immune reconstitution after CD34+ cell-selected PBSCT are unknown, however, substantial T-lymph...

The procedure for the in vitro reconstitution of active 50 S ribosomal subunits from Escherichiu coli first appeared in 1974 [ 11. The same group later reported the kinetic study of the reconstitution steps and gave the estimated sedimentation values of the reconstitution intermediates in sucrose gradient in 1976 [2]. Due to the relative difficulty in isolating the intermediates, no physical st...

UDP-glucose 4-epimerase from Saccharomyces fragilis has 1 mol of NAD firmly bound per mol of the dimeric apoenzyme. This prevents a direct study of the coenzyme binding site of the protein. Dissociation of the dimer with p-chloromercuribenzoate and its reconstitution with exogenous NAD or one of its analogues and 2-mercaptoethanol provides an indirect method of study of the site. Depending on t...

Canine X-linked severe combined immunodeficiency (XSCID) is due to mutations in the common gamma chain which is a subunit of the receptors of IL-2, IL-4, IL-7, IL-9 and IL-15. Bone marrow transplantation (BMT) of human XSCID patients without pretransplant conditioning (cytoablation) results in engraftment of donor T-cells and reconstitution of T-cell function but engraftment of few, if any, don...

We produced three batches of a human-serum-based enzyme reference material (ERM) enriched with human aspartate aminotransferase (EC 2.6.1.1), alanine aminotransferase (EC 2.6.1.2), creatine kinase (EC 2.7.3.2), and lactate dehydrogenase (EC 1.1.1.27). The added enzymes were not exhaustively purified; thus the final ERMs contained some enzymes as contaminants, of which only glutamate dehydrogena...

Developmental pluripotency-associated 5 (Dppa5) is an RNA binding protein highly expressed in undifferentiated pluripotent stem cells. Here, we demonstrate that Dppa5 is a regulator of hematopoietic stem cells (HSCs) that critically governs reconstitution capacity after bone marrow transplantation. Ectopic expression of Dppa5 followed by in vitro culture robustly increased HSC reconstitution le...
