Molecular Oncology, EarlyView.Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Transient Nonlinear Response of Impulsively-Loaded Circular Plates
Engineering Transactions, 1981 The finite element procedure used in this study is based on the incremental Lagrangian approach. Geometrical nonlinearity is included. The elastic viscoplastic material model is adopted in a form suitable for large strains. Linear 2-noded and parabolic 3-

Simplicial fixed point algorithm with 2d integer labels
Учёные записки Казанского университета: Серия Физико-математические науки, 2019 Simplicial fixed point algorithms can be based on either integer or vector labels. An apparent advantage of the algorithms with integer labels is their simplicity and stability under round-off errors due to the discrete nature of integer labels.

On Round-off Error for Adaptive Finite Element Methods
Procedia Computer Science, 2012 AbstractRound-off error analysis has been historically studied by analyzing the condition number of the associated matrix. By controlling the size of the condition number, it is possible to guarantee a prescribed round-off error tolerance. However, the opposite is not true, since it is possible to have a system of linear equations with an arbitrarily ...

Molecular Oncology, EarlyView.Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.
