Combination Therapy in Experimental Invasive Aspergillosis

Journal of Infectious Diseases, 1993
Combination antifungal therapy was assessed in an immunosuppressed rabbit model of invasive aspergillosis. Treatment with fluconazole, amphotericin B, or a combination of both significantly prolonged survival of animals lethally challenged with Aspergillus fumigatus.

Invasiveness of Fibroblasts From Experimental Cholesteatomas

Otology & Neurotology, 2001
Cultured fibroblasts derived from experimental gerbil cholesteatoma tissue exhibit an invasive phenotype in comparison with normal fibroblasts.Aural cholesteatomas are enlarging accumulations of keratin debris caused by keratinizing squamous epithelium in the middle ear.

Experimental Murine Invasive Pulmonary Aspergillosis

American Journal of Clinical Pathology, 1990
A new model of invasive pulmonary aspergillosis (IPA) was developed in immunosuppressed mice. Intranasal route of inoculation was used to deliver predictable numbers of Aspergillus flavus conidia. The LD50 was determined to be 2.7 X 10(2) viable conidia, and a combination of quantitative culture and determination of chitin content was shown to best ...

Intraspecific diversity poorly predicts invasibility and invasiveness: a meta-analysis of experimental invasions

2023
Identifying the biotic factors underlying invasion success is critical to understand the dynamics of biological invasions; and while some studies suggest that intraspecific diversity may play an important role, there has not been a systematic evaluation of the evidence.

Lack of bacterial invasion in experimental periodontitis

Journal of Clinical Periodontology, 1987
Abstract.The present study in the beagle dog was performed to analyze whether micro‐organisms from a subgingival microbiota could be translocated into or had the potential to invade the pocket epithelium and the gingival connective tissue during a phase of rapid breakdown of the attachment apparatus.

Bacterial Invasion in Experimental Gingivitis in Man

Journal of Periodontology, 1987
Gingival biopsies of the mesial papilla area of the first molar were obtained from each patient at 0‐, 14‐ and 21‐day intervals during plaque formation. The biopsies were fixed, serially sectioned, and Gram‐stained. The incidence and distribution of the bacteria‐like structures were studied by microscopy.

Evolution alters the consequences of invasions in experimental communities

Nature Ecology & Evolution, 2016
Evolution has the capacity to alter the course of biological invasions, although such changes remain mostly unexplored by experiments. Integrating evolution into studies of invasions is important, because species traits can potentially evolve in ways that either moderate or exacerbate the impacts of invasions.

Invasion: Experimental and Clinical Implications

Pathology, 1986
Five years ago, I had the opportunity to review the mechanism of metastasis in volume 4 of the text Metastasis , edited by Weiss and Gilbert; this was a superior and informative text on the mechanisms of cancer invasion and metastases. Unfortunately, the text by Mareel and Calman is shorter in scope and content than the Weiss and Gilbert text.

Sex steroids and experimental invasive atypia in mice

American Journal of Obstetrics and Gynecology, 1964
Abstract The effect of artificially administered progesterone or estrogen on podophyllin-induced atypia in the cervix and vagina of the castrated female mouse was studied. Four groups (estrogen, progesterone, both estrogen and progesterone, and controls) were studied in the first two experiments.

Anti-invasive activities of experimental chemotherapeutic agents

Critical Reviews in Oncology/Hematology, 1989
We have discussed a number of agents that affect invasion and we have grouped them according to their most probable targets. This strategy is based on the following hypothesis. Invasion is the result of cellular responses to extracellular signals. Candidate signals are components of the extracellular matrix, which are rendered inactive by the flavonoid
