Directional clustering through matrix factorization [PDF]

, 2016
This paper deals with a clustering problem where feature vectors are clustered depending on the angle between feature vectors, that is, feature vectors are grouped together if they point roughly in the same direction.

The adaptation of colorectal cancer cells when forming metastases in the liver: expression of associated genes and pathways in a mouse model

BMC Cancer, 2017
Background Colorectal cancer (CRC) is the second leading cause of cancer-related death in men and women. Systemic disease with metastatic spread to distant sites such as the liver reduces the survival rate considerably.

Herbal Therapeutics in Osteoporosis: Mechanisms, Evidence, and Translational Potential

Phytotherapy Research, EarlyView.
Schematic overview of bone remodeling dysregulation in osteoporosis and the multi‐target protective role of herbal therapeutics. ABSTRACT Osteoporosis is a chronic bone disease marked by reduced density and increased fracture risk. Current treatments face limitations in safety, efficacy, and long‐term adherence, prompting interest in alternative ...

Matrix interpretation of multiple orthogonality [PDF]

, 2010
In this work we give an interpretation of a (s(d + 1) + 1)-term recurrence relation in terms of type II multiple orthogonal polynomials.We rewrite this recurrence relation in matrix form and we obtain a three-term recurrence relation for vector ...

Singular random matrix decompositions: distributions. [PDF]

, 2002
Assuming that Y has a singular matrix variate elliptically contoured distribution with respect to the Hausdorff measure, the distributions of several matrices associated to QR, modified QR, SV and Polar decompositions of matrix Y are determined, for ...

From patient to tumor organoid: Culture protocol choice controls glioblastoma tumor architecture and identity

Brain Pathology, EarlyView.
How glioblastoma organoids are made shapes what they become. Fragment‐based cultures preserve extracellular matrix networks, cellular diversity, and primary tumor identity, whereas dissociation‐based cultures shift toward growth‐adapted states and simplified microenvironments. Abstract Patient‐derived tumor organoids are widely used in cancer research,

Subregion‐specific perineuronal net remodelling in the dorsal hippocampus drives vulnerability and resilience to chronic stress: The role of venlafaxine treatment

British Journal of Pharmacology, EarlyView.
Background and Purpose Neuronal plasticity enables the brain to adapt to internal and external demands by dynamically regulating synaptic connectivity and emotional circuitry. Impaired neuroplasticity represents a core pathophysiological framework of major depressive disorder, one of the leading causes of disability worldwide. Chronic stress is a major

Extracellular and macropinocytosis internalized ATP work together to induce epithelial–mesenchymal transition and other early metastatic activities in lung cancer

Cancer Cell International, 2019
Background Extracellular ATP (eATP) was shown to induce epithelial–mesenchymal transition (EMT), a very important early process in metastasis, in cancer cells via purinergic receptor signaling.

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.
