Mode of action of potential biocontrol agents against species and .

The antagonistic activities of three potential biocontrol agents (BCAs), , and , were tested in vitro against the target fungi , and . In vitro dual-culture assay revealed that the BCAs were able to inhibit the mycelial growth of most of the target fungi, with the most common mode of action being mycoparasitism. After 5 d of incubation, depending on the host-parasite interface, biotrophic mycoparasitism was observed via attachment structures on , and .

Reasons for delay in timely administration of adjuvant chemotherapy for patients with stage III colon cancer: a multicentre cohort study from the McGill University Department of Oncology.

Purpose: Adjuvant chemotherapy within 56 or 84 days following curative resection is globally accepted as the standard of care for stage III colon cancer as it has been associated with improved overall survival. Initiation of adjuvant chemotherapy within this time frame is therefore recommended by clinical practice guidelines, including the European Society for Medical Oncology. The objective of this study was to evaluate adherence to these clinical practice guidelines for patients with stage III colon cancer across the Rossy Cancer Network (RCN); a partnership of McGill University's Faculty of Medicine, McGill University Health Centre, Jewish General Hospital and St Mary's Hospital Center.

Variation at NRG1 genotype related to modulation of small-world properties of the functional cortical network.

Functional brain networks possess significant small-world (SW) properties. Genetic variation relevant to both inhibitory and excitatory transmission may contribute to modulate these properties. In healthy controls, genotypic variation in Neuregulin 1 (NRG1) related to the risk of psychosis (risk alleles) would contribute to functional SW modulation of the cortical network.

Modulation of brain network parameters associated with subclinical psychotic symptoms.

Objective: Static deficits in small-world properties of brain networks have been described in clinical psychosis, but task-related modulation of network properties has been scarcely studied. Our aim was to assess the modulation of those properties and its association with subclinical psychosis and cognition in the general population.

Method: Closeness centrality and small-worldness were compared between pre-stimulus baseline and response windows of an odd-ball task in 200 healthy individuals.

Cropping practices modulate the impact of glyphosate on arbuscular mycorrhizal fungi and rhizosphere bacteria in agroecosystems of the semiarid prairie.

A growing body of evidence obtained from studies performed under controlled conditions suggests that glyphosate use can modify microbial community assemblages. However, few studies have examined the influence of glyphosate in agroecosystems. We examined 4 wheat-based production systems typical of the Canadian prairie over 2 years to answer the following question: Does preseeding of glyphosate impact soil rhizosphere microorganisms? If so, do cropping practices influence this impact? Glyphosate caused a shift in the species dominating the arbuscular mycorrhizal fungal community in the rhizosphere, possibly through the modification of host plant physiology.

Positive cultures of organ preservation fluid predict postoperative infections in solid organ transplantation recipients.

Objective: The significance of positive cultures of organ preservation fluid (OPF) in solid organ transplantation is not known. We sought to describe the microbiology and define the clinical impact of positive OPF cultures.

Design: Retrospective cohort study.

Clostridium difficile colitis: increasing incidence, risk factors, and outcomes in solid organ transplant recipients.

Background: Clostridium difficile-associated diarrhea (CDAD) is an increasingly important diagnosis in solid organ transplant recipients, with rising incidence and mortality. We describe the incidence, risk factors, and outcomes of colectomy for CDAD after solid organ transplantation.

Methods: Patients with CDAD were identified from a prospective transplant database.

Complications of ureterovesical anastomosis in adult renal transplantation: comparison of the Lich-Gregoire and the Taguchi techniques.

Background: Our aim is to identify the incidence of urologic complications in adult renal transplantation comparing two different ureterovesical anastomosis techniques, the Taguchi (T) and Lich-Gregoire (LG).

Material/methods: Retrospective analysis of adult renal transplants performed at the MUHC between 2000-2009. Excluded: multi-organ transplants, re-do transplants, variant ureteric anastomosis and patients received grafts from UNOS ECD.
