The ant colony optimization (ACO) algorithm is a new heuristic algorithm that offers good robustness and searching ability. With in-depth exploration, the ACO algorithm exhibits slow convergence speed, and yields local optimization solutions. Based on analysis of the ACO algorithm and the genetic algorithm, we propose a novel hybrid genetic ant colony optimization (NHGAO) algorithm that integra...

Cure rates for acute myeloid leukemia (AML) remain suboptimal; thus new treatment strategies are needed for this deadly disease. Poor clinical outcomes have been associated with overexpression of the anti-apoptotic Bcl-2 family proteins Bcl-2, Bcl-xL, and Mcl-1, which have garnered great interest as therapeutic targets. While the Bcl-2-selective inhibitor ABT-199 has demonstrated promising prec...

A monoclonal antibody (mAb) (T-199) of IgG1 isotype was raised against medulloblastoma by immunizations of mice with the medulloblastoma cell line TE-671. Studies of the specificity of mAb T-199 on cell lines as well as fresh frozen sections of normal and malignant tissues revealed the antigen in high amounts on the cell surface of neuroectodermally derived tumors such as medulloblastoma, neuro...

The aggressive biological behavior of mantle cell lymphoma (MCL) and its short response to current treatment highlight a great need for better rational therapy. Herein, we investigate the ability of ABT-199, the Bcl-2-selective BH3 mimetic, to kill MCL cells. Among MCL cell lines tested (n = 8), only three were sensitive (LD50 < 200 nM). In contrast, all primary MCL samples tested (n = 11) were...

The prepro-thyrotropin-releasing hormone (ppTRH)-derived peptide, ppTRH178-199, has been proposed to inhibit ACTH release at the level of the pituitary and attenuate prolactin and behavioral responses to stress as well. The objective of this study was to elucidate a possible link between the effects of ppTRH178-199 and glucocorticoids on the inhibition of ACTH release in corticotrophs. Compared...
