Due to numerous human activities, organisms have been transported and either accidentally or deliberately introduced all around the globe. Biological invasions are now considered to be one of the main drivers of global change because many invasive plants have severe ecological, economic, and health consequences.

Invasive predators affect community‐wide pollinator visitation
Ecological Applications, 2022AbstractDisruption of plant–pollinator interactions by invasive predators is poorly understood but may pose a critical threat for native ecosystems. In a multiyear field experiment in Hawai'i, we suppressed abundances of globally invasive predators and then observed insect visitation to flowers of six native plant species.

Cell communication networks in cancer invasion
Current Opinion in Cell Biology, 2011The invasion of cancer is a major clinical problem. It is now apparent that invasion is not a simply a cancer cell autonomous process but relies on a complex network of paracrine interactions. Furthermore, this network can change as cancer cells disseminate.

Long‐term community non‐invasive ventilation
Internal Medicine Journal, 2010AbstractBackground: Community non‐invasive ventilation (NIV) is increasingly used to treat chronic type 2 respiratory failure. Minimal information is published regarding patient acceptability or benefit. Records at our institution have information gaps.Aims: To survey patients on chronic NIV – collecting demographics, ventilator usage, health‐related

Invasiveness in plant communities with feedbacks
Ecology Letters, 2007AbstractThe detrimental effects of invasive plant species on ecosystems are well documented. While much research has focused on discovering ecological influences associated with invasiveness, it remains unclear how these influences interact, causing some introduced exotic species to become invasive threats. Here we develop a framework that incorporates

Community changes following shrub invasion of grassland
Oecologia, 1986We studied the development of the shrub Baccharis pilularis ssp consanguinea and its effects on herbs of the annual grassland in Northern California. A series of shands of Baccharis was sampled of ages ranging from 1 yr to>9 yr, representing most of the life cycle of the shrub. In each stand we examined shrub biomass, structure and litterfall.

Ecological Factors Affecting Community Invasibility
2009What makes a community invasible? For over a century ecologists have sought to understand the relative importance of biotic and abiotic factors that determine community composition. The fact that we are still exploring this topic today hints at both its importance and complexity.

Rapid Communication: Minimally Invasive Urologic Surgery Curricula
Journal of Endourology, 2007Surgical education programs are being challenged to provide comprehensive training in the ever-expanding technologies and techniques. We present dedicated training curricula for several aspects of minimally invasive urologic surgery in an effort to provide a uniform training experience for all residents.Five components of the curricula were developed ...

A Non-Invasive Communication Device for the Paralyzed
min - Minimally Invasive Neurosurgery, 2002An EEG-based communication system has been developed to re-establish communication in severely paralyzed patients who operate the device by generating shifts of their slow cortical potentials. Training to gain control over slow cortical potentials was based on visual feedback and operant conditioning strategies.

Minimally Invasive Parathyroidectomy
Archives of Surgery, 2011Minimally invasive parathyroidectomy (MIP) for primary hyperparathyroidism can be successfully performed using preoperative sestamibi scan and intraoperative radioguidance without the need of measurement of intraoperative parathyroid hormone (PTH) levels.
