Reports of true morels (Morchella) fruiting on conifer burn sites are common in western North America where five different fire-adapted species of black morels (Elata Clade) have been documented based on multilocus phylogenetic analyses. Fruiting of post-fire morels in eastern North America, by comparison, are rare and limited to a report from Minnesota in 1977 and eastern Ontario in 1991. Here, nuc rDNA internal transcribed spacer (ITS1-5.8S-ITS2 = ITS) sequences were used to identify the post-fire morel t...
Growing concern about the risk associated with increasing environmental mercury (Hg) concentrations has resulted in a focus on the relationships between intercontinental emitted and accumulated Hg. We use a global biogeochemical Hg model with 8 continental regions and a global ocean to evaluate the legacy impacts of historical anthropogenic releases (2000BCE to 2008AD) on global source-receptor relationships of Hg. Legacy impacts of historical anthropogenic releases are confirmed to be significant on the so...
Recent and compelling archaeological evidence attests to human presence ∼14.5 thousand years ago (Kya) at multiple sites in South America and a very early exploitation of extreme high-altitude Andean environments. Considering that, according to genetic evidence, human entry into North America from Beringia most likely occurred ∼16 Kya, these archeological findings would imply an extremely rapid spread along the double continent. To shed light on this issue from a genetic perspective, we first completely...
Few studies in North America have quantified the risks of second malignant neoplasms (SMNs) among survivors of childhood non-central nervous system (non-CNS) embryonal tumours due to their rarity. We aimed to investigate these risks by combining population-based data from the United States of America and Canada.
Most thyroid surgery in North America is completed via a cervical incision, which leaves a permanent scar. Approaches without cutaneous incisions offer aesthetic advantages. This series represents the largest series of transoral vestibular approaches to the central neck in North America, and the first published reports of robotic transoral vestibular thyroidectomy for thyroid carcinoma.
Tricholoma matsutake, known widely as "matsutake," has great commercial and cultural significance in Japan. Because Japanese production is insufficient to meet the high domestic demand, morphologically similar mushrooms, thought by many to belong to T. magnivelare, are imported from western North America. However, molecular data produced since the early 2000s have indicated that more than one species of matsutake occur in North America and this raises the question of correct naming for the different species...
Sclerodermus Latreille, 1809 (Hymenoptera: Bethylidae), are parasitoids of wood-boring beetle larvae that can co-infest furniture and homes attacked by such larvae. This can result in the human inhabitants receiving stings from adult female wasps as they wander in search of new hosts. Herein, I report the first infestation of Sclerodermus macrogaster (Ashmead, 1887) of a home in North America and provide a review of Sclerodermus biology and clinical signs relevant to their pestiferous nature.
White-nose syndrome, first diagnosed in North America in 2006, causes mass deaths among bats in North America. We found the causative fungus, Pseudogymnoascus destructans, in a 1918 sample collected in Europe, where bats have now adapted to the fungus. These results are consistent with a Eurasian origin of the pathogen.
Seven species of Cortinarius, subgenus Telamonia, section Colymbadini and /Flavobasilis, are reported from conifer forests in the mountains of western North America. They typically produce basidiomes in the spring and summer. Only one species, C. colymbadinus, is widespread, occurring in Europe and western North America, but to date not reported from California. Cortinarius bridgei, C. flavobasilis, C. rumoribrunsi, C. vernalishastensis, and C. vernalisierraensis are new species. The first two are found thr...
Despite constituting half the population, women represent a minority of active physicians and hold a small proportion of faculty leadership positions in North America. However, dermatology is one of the few specialties where women comprise a substantial portion of the workforce. This study explores extent and contributors to gender disparity in academic dermatology faculty positions, leadership, and research.
Screening for lung cancer using low-dose computed tomography has already been implemented in North America following the results of the National Lung Screening Trial. Outside North America, clinicians and researchers are addressing issues that may have a major impact on the success of screening programmes by reviewing results of existing trials and by designing new research and pilot programmes. This review summarises the work that has been done to try to answer the remaining questions and highlights potent...
Millions of radiologic examinations requiring the use of iodinated contrast are performed yearly in North America. Triiodobenzoic acid, the contrast agent molecule currently in use, is a benzene ring covalently bonded to the 3 iodine atoms. Iodinated contrast media can be divided in 4 categories: ionic monomers, ionic dimers, nonionic monomer, and nonionic dimers. Currently, second- and third-generation nonionic low-osmolar and iso-osmolar contrast media are used in clinical practice. The search for a safer...
