Abstract
We investigated the outcomes after adult haploidentical (haplo) and matched unrelated donor (MUD) hematopoietic cell transplantation (HCT) in a single-center study (n = 452) including 276 MUD and 176 haplo transplants. Myeloablative (37%) and reduced-intensity conditioning (63%) were performed. Graft sources included peripheral blood (50%) and bone marrow (50%). GVHD prophylaxis included tacrolimus/methotrexate (53%) and post-transplant cyclophosphamide-based (47%). In MUD versus haplo HCT recipients, a similar incidence of neutrophil engraftment (18 vs 17 days, p = 0.895), grade II-IV acute GVHD (51% vs 50%, p = 0.773), relapse (26% vs 23%, p = 0.578), non-relapse mortality (22% vs 23%, p = 0.817), 1-year disease-free survival (62% vs 63%. p = 0.921), and 1-year overall survival (73% vs 74%, p = 0.744) were observed. Earlier platelet engraftment (22 vs 27 days, p < 0.001) and higher chronic GVHD (45% vs 35%, p = 0.040) were noted in MUD as compared to haplo HCT. Allogeneic transplantation should be done promptly whenever indicated, utilizing either matched unrelated or haploidentical donors.

Abstract
Aflatoxins are toxic and carcinogenic components produced by some Aspergillus species such as Aspergillus flavus. Polyketide synthases enzyme (PKS) plays a central role in aflatoxin s biosynthesis of in Aspergillus flavus, especially the product template (PT) domain, which controls the aldol cyclization of the polyketide forerunner during the biosynthesis of the aflatoxin pathway process. Here, we apply the in silico approaches to validate 623 natural components obtained from the South African Natural Compound Database (SANCDB), to distinguish the PT domain s prospected inhibitors. From the 623 compounds, docking results showed that there are 330 different compounds with energy binding lower than the natural substrate (palmitic acid or PLM) of the Product Templet domain (PT). Three factors were selected to determine the best 10 inhibiting components; 1) energy binding, 2) the strengthen chemical interactions, 3) the drug-likeness. The top ten inhibiting components are kraussianone 6, kraussianone 1, neodiospyrin, clionamine D, bromotopsentin, isodiospyrin, spongotine A, kraussianone 3, 14β-Hydroxybufa-3,5,20,22-tetraenolide and kraussianone 7. The chemical interactions between 3HRQ domain and the natural substrate in the active site amino acids are highly similar to the 3HRQ with the top ten components, but the main differences are in the binding energy which is the best in the top ten ligands. Those ten components give successful inhibition with PT domain which will lead to the formula to be used for inhibition and control aflatoxin contamination of agriculture crop yields and lessen the degree of harming and sicknesses that are coming about because of acquiring measures of aflatoxin.

Abstract
The spread of fungal growth causes enormous economic, agricultural, and health problems for humans, such as Aspergillus sp., which produce aflatoxins. Thus, the inhibition of aflatoxin production became a precious target. In this research, the thioesterase (TE) domain from Polyketide synthase enzyme was selected to employ the in silico docking, using AutoDock Vina, against 623 natural compounds from the South African natural compound database (SANCDB), to identify potential inhibitors that can selectively inhibit thioesterase domain. The top ten inhibitors components were pinocembrin, typhaphthalide, p-coumaroylputrescine, dilemmaone A, 9-angelylplatynecine, 2,4,6-octatrienal, 4,8-dichloro-3,7-dimethyl-, (2e,4z,6e)-, lilacinobiose, 1,3,7-octatriene, 5,6-dichloro-2-(dichloromethyl)-6-methyl-, [r*,s*-(e)]-(-)- (9ci), lilacinobiose, 1,3,7-octatriene, 5,6-dichloro-2-(dichloromethyl)-6-methyl-, [r*,s*-(e)]-(-)- (9ci), 1,3,7-octatriene, 1,5,6-trichloro-2-(dichloromethyl)-6-methyl-, [r*,s*-(z,e)] and 9-angelylhastanecine and that depending on the lowest binding energy, the best chemical interactions and the best drug-likeness. The results of those components gave successful inhibition with the thioesterase domain. So, they can be used for inhibition and controlling aflatoxin contamination of agriculture crop yields, specially, pinocembrin which gave promising results.Communicated by Ramaswamy H. Sarma.

Abstract
The influence of lithium on cell growth and cell viability was studied in short-term cultures of a neural precursor cell line (NT) developed from a murine teratocarcinoma. At very low concentrations ranging from 0.1 mM to 1 mM Li2CO3 (equivalent to therapeutic blood concentrations) there was no difference between untreated and treated cultures. 10 mM lithium (Li+) was found to be toxic with 33% of cell death, while there was inhibition of growth without cell death at concentrations of 2.5 mM and 5 mM of Li+. In experiments where 2.5 mM Li+ was added at the time of seeding, there was growth arrest on day 1 followed by recovery on day 2. Flow cytometric analysis revealed that cells treated with Li+ were blocked in S phase. At 5 mM concentration of Li+, the recovery occurred on day 3 and the plating efficiency was significantly low. The ability to form colonies in soft agar was reduced at 2.5 mM and 5 mM concentrations of Li+ to an equal extent. Thus, Li+ has growth inhibitory as well as anchorage-independent growth reducing effects. The NT cell line therefore would be a good model system to study the mechanism of teratogenic effect of Li+.

Abstract
In this paper we have used a monoclonal antibody to CD34 an antigen expressed solely on stem cells, and stem cell colony assays to show that umbilical cord blood has nearly the same number of functional stem cells as compared to normal bone-marrow. The number of CD34+ve cells in cord blood being 2 to 2.7 per cent, whereas bone-marrow had 3 to 3.5 per cent. The multi-potent colony forming cells (CFU-GEMM) were 60 +/- 18 in cord blood per 2 x 10(5) mononuclear cells (MNCs), whereas normal bone-marrow had 70 +/- 10 per 2 x 10(5) MNCs. Enrichment of these stem cells on Percoll gradients was successful for normal bone-marrow but not for cord blood.

Abstract
Our earlier studies have shown that monoclonal antibody (Mab) 3F8E3 generated against a head and neck cancer cell line LICR-LON-HN2 showed reactivity with squamous cell carcinoma (SCC) irrespective of the tissue of origin and identified antigens on SCC cell lines AW 13516 and AW 8507. The affinity constants (Ka) for binding of Mab 3F8E3 to AW 13516 and AW 8507 cell lines were 6.2 x 10(8) and 4.3 x 10(8) mol/l and it identified 6.8 x 10(4) and 3.77 x 10(4) sites/cell, respectively, as determined by Scatchard analysis. Treatment of both the cell lines with recombinant human interferon-alpha (rHu-IFN alpha) increased the binding affinity of the Mab but did not increase the number of binding sites on the SCC cell lines. Shedding of antigen recognised by the Mab in the culture supernatant of the cell lines was reduced after rHu-IFN alpha treatment. The results suggest that rHu-IFN alpha may bring about a firm anchorage of the tumour associated antigen on the SCC cells. Cells modulated with rHu-IFN alpha may serve as better targets for assessing cell mediated as well as Mab mediated cytotoxicity in oral cancer patients.

Abstract
Three anti K562 monoclonal antibodies (MAb) 4.3, 4.6 and 4.8 reacting predominantly with cells of myeloid lineage, were tested for antibody dependent cellular cytotoxicity (ADCC) and complement dependent cytotoxicity (CDC). MAb 4.6 (IgG3k) effectively mediated ADCC against K562 cells and fresh leukemic targets with effectors from healthy donors. However, for ADCC on chronic myeloid leukemia (CML) targets, effectors from CML patients in remission needed modulation with IL-2. All MAb showed significant CDC against peripheral blood (PB) and bone marrow (BM) cells obtained from CML patients in chronic phase, and untreated acute myeloid leukemia (AML) patients. MAb displayed no CDC against PB and BM cells from CML patients in remission and BM cells of Hodgkin's Disease (HD) patients with normal BM cellularity. In clonogenic assay, colony forming units (CFU) in the BM aspirate obtained from CML patients in chronic phase were significantly reduced by treatment with MAb and complement.
