Functional querying in graph databases

open access: yesVietnam Journal of Computer Science, 2017
The paper is focused on a functional querying in graph databases. We consider labelled property graph model and mention also the graph model behind XML databases. An attention is devoted to functional modelling of graph databases both at a conceptual and

Mechanical force induces mitochondrial fission

open access: yeseLife, 2017
Eukaryotic cells are densely packed with macromolecular complexes and intertwining organelles, continually transported and reshaped. Intriguingly, organelles avoid clashing and entangling with each other in such limited space. Mitochondria form extensive

Mitochondrial fission factor promotes cisplatin resistancein hepatocellular carcinoma

open access: yesActa Biochimica et Biophysica Sinica, 2022
Hepatocellular carcinoma (HCC) is the most common primary liver tumor and one of the leading causes of cancer-related death worldwide. Chemotherapeutic agents/regimens such as cisplatin (DDP) are frequently used for advanced HCC treatment.

Mitochondrial Calcium-Triggered Oxidative Stress and Developmental Defects in Dopaminergic Neurons Differentiated from Deciduous Teeth-Derived Dental Pulp Stem Cells with MFF Insufficiency

open access: yesAntioxidants, 2022
Mitochondrial fission factor (MFF) is an adapter that targets dynamin-related protein 1 from the cytosol to the mitochondria for fission. Loss-of-function MFF mutations cause encephalopathy due to defective mitochondrial and peroxisomal fission 2 (EMPF2).

Modifications of thick-target model: re-acceleration of electron beams by static and stochastic electric fields [PDF]

open access: yes, 2014
We study two modifications of the collisional thick-target model (CTTM) based on the global and local re-acceleration of non-thermal electrons by static and stochastic electric fields during their transport from the coronal acceleration site to the thick-

Mitochondrial fission promotes self-renewal and tumorigenic potential in prostate cancer

open access: yesMolecular & Cellular Oncology, 2019
The emergence of therapy-resistant cancer stem cells (CSCs) limit the efficacy of prostate cancer treatment. Using genetic knockdown and chemical inhibitors, we demonstrate the critical role of Bromodomain Containing 4 (BRD4) in promoting mitochondrial ...
