Genus \u3ci\u3eHydrosmecta\u3c/i\u3e C. G. Thomson: a review of species occurring in eastern Canada (Coleoptera, Staphylinidae, Aleocharinae)

Species of Hydrosmecta C. G. Thomson, occurring in eastern Canada, are studied and reviewed. Six species are recognized, and two of them are described as new to science. The new species are: Hydrosmecta canadensis Webster and Klimaszewski, new species, and Hydrosmecta minutissimoides Webster and Klimaszewski, new species. Two species described in the USA are recorded from Canada and New Brunswick for the first time: Hydrosmecta caduca Casey and Hydrosmecta dulcis Casey. New distribution and collection data, diagnoses, a key for species identification, and images of habitus and genital structures are provided. Hydrosmecta newfoundlandica Klimaszewski and Langor, 2011, is transferred to the genus Atheta Thomson based on morphology of genital structures

A new cryptic species of \u3ci\u3eAleochara\u3c/i\u3e Gravenhorst associated with \u3ci\u3eMarmota monax\u3c/i\u3e (Linnaeus) burrows and caves in North America (Coleoptera: Staphylinidae: Aleocharinae)

A new cryptic species, Aleochara (Xenochara) castaneimarmotae Klimaszewski, Webster, and Brunke, new species (Coleoptera: Staphylinidae: Aleocharinae), associated with Marmota monax (Linnaeus) burrows and caves in eastern North America, is described and illustrated. A key to Canadian species of subgenus Xenochara Mulsant and Rey and revised distributions of the taxonomically difficult fumata species group are provided. Aleochara quadrata Sharp is recorded from Washington and Oregon for the first time

Description of \u3ci\u3eHydrosmectomorpha\u3c/i\u3e Klimaszewski and Webster, a new subgenus of \u3ci\u3eAtheta\u3c/i\u3e C. G. Thomson, with three new Canadian species (Coleoptera: Staphylinidae: Aleocharinae)

A new subgenus, Hydrosmectomorpha Klimaszewski and Webster, of the genus Atheta C. G. Thomson (Coleoptera: Staphylinidae: Aleocharinae) is erected to accommodate three new species and Atheta newfoundlandica (Klimaszewski and Langor). The new species are: Atheta (Hydrosmectomorpha) meduxnekeagensis Webster and Klimaszewski, new species; Atheta (Hydrosmectomorpha) quebecensis Webster and Klimaszewski, new species, Atheta (Hydrosmectomorpha) vincenti Webster and Klimaszewski, new species. The new species are described, illustrated, and a key is provided. Atheta newfoundlandica (Klimaszewski and Langor), was recently transferred from Hydrosmecta C.G. Thomson to an unspecified subgenus of Atheta. New habitat/collection data are presented for the treated species

DNA Damage, Somatic Aneuploidy, and Malignant Sarcoma Susceptibility in Muscular Dystrophies

Albeit genetically highly heterogeneous, muscular dystrophies (MDs) share a convergent pathology leading to muscle wasting accompanied by proliferation of fibrous and fatty tissue, suggesting a common MD–pathomechanism. Here we show that mutations in muscular dystrophy genes (Dmd, Dysf, Capn3, Large) lead to the spontaneous formation of skeletal muscle-derived malignant tumors in mice, presenting as mixed rhabdomyo-, fibro-, and liposarcomas. Primary MD–gene defects and strain background strongly influence sarcoma incidence, latency, localization, and gender prevalence. Combined loss of dystrophin and dysferlin, as well as dystrophin and calpain-3, leads to accelerated tumor formation. Irrespective of the primary gene defects, all MD sarcomas share non-random genomic alterations including frequent losses of tumor suppressors (Cdkn2a, Nf1), amplification of oncogenes (Met, Jun), recurrent duplications of whole chromosomes 8 and 15, and DNA damage. Remarkably, these sarcoma-specific genetic lesions are already regularly present in skeletal muscles in aged MD mice even prior to sarcoma development. Accordingly, we show also that skeletal muscle from human muscular dystrophy patients is affected by gross genomic instability, represented by DNA double-strand breaks and age-related accumulation of aneusomies. These novel aspects of molecular pathologies common to muscular dystrophies and tumor biology will potentially influence the strategies to combat these diseases
