Artificial organs

Wang Y, Nguyen KT, Ismail E, Donoghue L, Giridharan GA, Sethu P, Cheng X.
PMID: 34866200
Artif Organs. 2021 Dec 06; doi: 10.1111/aor.14133. Epub 2021 Dec 06.

BACKGROUND: Patients with continuous flow ventricular assist devices (CF-VADs) are at high risk for non-surgical bleeding, speculated to associate with the loss of pulsatility following CF-VAD placement. It has been hypothesized that continuous shear stress causes elongation and increased...

Senescence, a state of permanent cell cycle arrest, can be induced by DNA damage. This process, which was initially described in fibroblasts, is now recognized to occur in stem cells. It has been well characterized in cell lines, but...

Molecular docking of C-Jun-N-Terminal Kinase (Jnk) with amino-pyrimidine derivatives.

Bioinformation

Meenakumari K, Bupesh G.
PMID: 32884210
Bioinformation. 2020 Jun 30;16(6):462-467. doi: 10.6026/97320630016462. eCollection 2020.

It is of interest to document the molecular docking of C-Jun-N-Terminal Kinase (Jnk) (known structure with PDB ID: 1PMN) with amino-pyrimidine derivatives in the context of Alzheimer's Disease (AD). We report the optimal binding features (binding energy, interacting residues,...
