alignant behaviors of triple-negative breast cancer cells, which suggested miR-331-3p as a potential target for the treatment of triple-negative breast cancer.Background Stroke survivors find it difficult to participate in daily activities, despite their improvement throughout the rehabilitation process. Thus, it has been questioned whether day-rehabilitation services provide adequate preparation for participation and reintegration into the community. Self-management programs can improve survivors' self-efficacy to manage their condition and participation. Improving Participation After Stroke Self-Management program (IPASS) is an occupational therapy-based group intervention developed in the United States, which has been effective in improving participation outcomes.Objective To evaluate the feasibility and effectiveness of the IPASS adapted for an Israeli population of individuals admitted to a day-rehabilitation center after stroke.Methods A single-center, randomized, assessor-blind study was conducted. Eligible participants were randomized to receive the IPASS (intervention group), in addition to standard individual therapy or standard care only (control group). Feasibility was based on attendance rate and a feedback questionnaire. Effectiveness was evaluated with the Functional Independence Measure (FIM), the Reintegration to Normal Living Index (RNLI) and self-efficacy questionnaires.Results Sixty participants were included, of which 39 completed baseline and post-intervention evaluations. The intervention group improved significantly in the FIM scores (p .05). Moderate effect sizes (≥0.35) were found for the FIM and RNLI, and large effect sizes (≥0.65) for two subcategories in the participation self-efficacy questionnaire.Conclusions The results support the feasibility of the adapted IPASS, and show a trend for positive effects in improving participation and self-efficacy in managing participation in home and community activities, for an Israeli post-stroke population.We previously reported on a mutant lipase KV1 (Mut-LipKV1) from Acinetobacter haemolyticus which optimal pH was raised from 8.0 to 11.0 after triple substitutions of surface aspartic acid (Asp) with lysine (Lys). Herein, this study further examined the Mut-LipKV1 by molecular docking, molecular dynamics (MD) simulations and molecular mechanics-Poisson Boltzmann surface area (MM-PBSA) calculations to explore the structural requirements that participated in the effective binding of tributyrin and its catalytic triad (Ser165, Asp259 and His289) and identify detailed changes that occurred post mutation. Mut-LipKV1 bound favorably with tributyrin (-4.1 kcal/mol) and formed a single hydrogen bond with His289, at pH 9.0. Despite the incongruent docking analysis data, results of MD simulations showed configurations of both the tributyrin-Mut-LipKV1 (RMSD 0.3 nm; RMSF 0.05 - 0.3 nm) and the tributyrin-wildtype lipase KV1 (tributyrin-LipKV1) complexes (RMSD 0.35 nm; RMSF 0.05 - 0.4 nm) being comparably stable at pH 8.0. MM-PBSA analysis indicated that van der Waals interactions made the most contribution during the molecular binding process, with the Mut-LipKV1-tributyrin complex (-44.04 kcal/mol) showing relatively lower binding energy than LipKV1-tributyrin (-43.83 kcal/mol), at pH 12.0. All tributyrin-Mut-LipKV1 complexes displayed improved binding free energies over a broader pH range from 8.0 - 12.0, as compared to LipKV1-tributyrin. Future empirical works are thus, important to validate the improved alkaline-stability of Mut-LipKV1. In a nutshell, our research offered a considerable insight for further improving the alkaline tolerance of lipases.Communicated by Ramaswamy H.

The implication of PAX2 transcription factor in regulating several ATP-binding cassette (ABC) transporter proteins that are responsible for the acquisition of drug resistance in PDAC makes it a potential target for treatment purposes. In this study, the 3D structure of PAX2 protein was modeled, and the response of key amino acids to perturbation was identified. Subsequently, kappadione, a vitamin K derivative, was found to bind efficiently to PAX2 with a binding energy of -9.819 kcal/mol. The efficacy of mechanism and mode of binding was studied by docking the protein with DNA in the presence and absence of the drug. The presence of kappadione disrupted DNA binding with key effector resides, preventing the DNA from coming into contact with the binding region essential for protein translation. By occupying the DNA binding region and replacing it with a ligand, the mechanism by which DNA interacts with PAX2 could be manipulated. Inhibition of PAX2-DNA binding using kappadione and other small molecules can prove to be beneficial for combating chemoresistance in PDAC, as proposed through in silico approaches.Communicated by Ramaswamy H. Sarma.The presence or absence of cytogenetic mutations is proposed to be responsible for the pathogenesis of acute myeloid leukaemia (AML). However, the current classification system is inadequate to elucidate the molecular heterogeneity of the disease, and therapy failures frequently occur. Leukaemia stem cells (LSCs) initiate and maintain the clonal hierarchy of AML and exhibit properties of self-renewal remaining recalcitrant to conventional chemotherapy. In this study, we identified a novel long non-coding RNA (lncRNA) MAGI2 antisense RNA 3 (MAGI2-AS3) in AML and investigated its functional role in regulating LSCs self-renewal. LSCs were identified by immunoprofiling of CD34+ CD123+ in AML patients' marrow. MAGI2-AS3 exhibited a poor expression level in LSCs than the normal human haematopoietic stem cells. Lentivirus-mediated upregulation of MAGI2-AS3 or leucine-rich repeats and Ig-like domains 1 (LRIG1) impaired LSCs self-renewal. MAGI2-AS3-overexpressed LSCs acquired the ability of self-renewal following lentivirus-mediated knockdown of LRIG1.
