Hurricane activity and the large-scale pattern of spread of an invasive plant species. [PDF]

PLoS ONE, 2014
Disturbances are a primary facilitator of the growth and spread of invasive species. However, the effects of large-scale disturbances, such as hurricanes and tropical storms, on the broad geographic patterns of invasive species growth and spread have not

Minimally Invasive Thymoma with Extensive Intravascular Growth [PDF]

Japanese Journal of Clinical Oncology, 1999
A 70-year-old male with grossly non-invasive thymic tumor associated with myasthenia gravis was subjected to thymothymectomy. Microscopic examination showed extensive intravascular tumor extensions into veins of thymic tissue and surrounding muscles and a minute direct invasion of the thymic tissue.

Invasion Percolation and Eden Growth: Geometry and Universality

Physical Review Letters, 1996
The mapping of optimal paths in the strong disorder limit to the strands of invasion percolation clusters is shown to lead to a new universal property of these clusters. We suggest that the corresponding strands arising in the annealed Eden growth process are in the same universality class as directed polymers in weak quenched disorder with an upper ...

Loss of Ambra1 promotes melanoma growth and invasion [PDF]

Nature Communications, 2021
AbstractMelanoma is the deadliest skin cancer. Despite improvements in the understanding of the molecular mechanisms underlying melanoma biology and in defining new curative strategies, the therapeutic needs for this disease have not yet been fulfilled.

The Impact of Phenotypic Switching on Glioblastoma Growth and Invasion

PLoS Computational Biology, 2012
The brain tumour glioblastoma is characterised by diffuse and infiltrative growth into surrounding brain tissue. At the macroscopic level, the progression speed of a glioblastoma tumour is determined by two key factors: the cell proliferation rate and the cell migration speed.

Stromal myofibroblasts are drivers of invasive cancer growth [PDF]

International Journal of Cancer, 2008
AbstractTissue integrity is maintained by the stroma in physiology. In cancer, however, tissue invasion is driven by the stroma. Myofibroblasts and cancer‐associated fibroblasts are important components of the tumor stroma. The origin of myofibroblasts remains controversial, although fibroblasts and bone marrow‐derived precursors are considered to be ...

Mss2 shapes the virulence of Candida albicans through reactive oxygen species (ROS) and calcium signaling, independent of direct transcriptional control

Virulence
Mitochondrial function is essential for virulence in Candida albicans, yet the mechanism by which mitochondria influence pathogenesis remains largely undefined.

Enhanced shoot investment makes invasive plants exhibit growth advantages in high nitrogen conditions

Brazilian Journal of Biology, 2018
Resource amendments commonly promote plant invasions, raising concerns over the potential consequences of nitrogen (N) deposition; however, it is unclear whether invaders will benefit from N deposition more than natives.

The MET oncogene as a therapeutical target in cancer invasive growth

Frontiers in Pharmacology, 2012
The MET proto-oncogene, encoding the tyrosine kinase receptor for Hepatocyte Growth Factor (HGF) regulates invasive growth, a genetic program that associates control of cell proliferation with invasion of the extracellular matrix and protection from ...

A Case of Invasive Thymoma with Endotracheal Polypoid Growth [PDF]

Tuberculosis and Respiratory Diseases, 2012
Thymomas are one of the most common neoplasms of the mediastinum derived from thymic epithelium. It is common that invasive thymoma invades the lung, pericardium, and great vessels. Airway compression by mass effect also occurs, but direct polypoid tumor growth into the airway is extremely rare.
