Using a similar Anelloviridae approach but with recovery of complete genomes by PCR, we identified a diverse group of single-stranded vi Genomoviridae ruses in yellow-bellied marmot (Marmota flaviventer) fecal samples. From 13 fecal samples we identified viruses Cressdnaviricota in the family Genomoviridae (n = 7) and Anelloviridae (n = 1), and several others that ware part of the larger Cressdnaviricota phylum but not within established families (n = 19). There were also circular DNA molecules identified (n = 4) that appear to encode one viral-like gene and have genomes of <1545 nts. This study gives a snapshot of viruses associated with marmots based on fecal sampling. -

The Analysis of Regulatory Sequences Required for High Level Induction of Rat Á2u-Globulin Gene Expression by Dexamethasone
129 The analysis of regulatory sequences required for high level induction of rat á2u-globulin gene expression by dexamethasone K S Wang and R B Hodgetts Department of Biological Sciences, University of Alberta, Edmonton, Alberta T6G 2E9, Canada (Requests for offprints should be addressed to R B Hodgetts) (K S Wang is now at Department of Adult Oncology, Dana-Farber Cancer Institute, Boston, Massachusetts 02115, USA) ABSTRACT The á2u-globulins are the major urinary proteins in response element 5*-AGAACAnnnTGTACC-3*,is adult male rats. They are encoded by a gene family, situated 513 bp upstream of the transcription start the expression of which is under multihormonal site.

On the Stability of Sequences Inserted Into Viral Genomes Anouk Willemsen1,*,† and Mark P
Virus Evolution, 2019, 5(2): vez045 doi: 10.1093/ve/vez045 Review article On the stability of sequences inserted into viral genomes Anouk Willemsen1,*,† and Mark P. Zwart2,*,‡ 1Laboratory MIVEGEC (UMR CNRS IRD University of Montpellier), Centre National de la Recherche Scientifique (CNRS), 911 Avenue Agropolis, BP 64501, 34394 Montpellier cedex 5, France and 2Netherlands Institute of Ecology (NIOO-KNAW), Postbus 50, 6700 AB, Wageningen, The Netherlands *Corresponding author: E-mail: [email protected]; [email protected] †http://orcid.org/0000-0002-8511-3244 ‡http://orcid.org/0000-0003-4361-7636 Abstract Viruses are widely used as vectors for heterologous gene expression in cultured cells or natural hosts, and therefore a large num- ber of viruses with exogenous sequences inserted into their genomes have been engineered. Many of these engineered viruses are viable and express heterologous proteins at high levels, but the inserted sequences often prove to be unstable over time and are rapidly lost, limiting heterologous protein expression. Although virologists are aware that inserted sequences can be unstable, processes leading to insert instability are rarely considered from an evolutionary perspective. Here, we review experimental work on the stability of inserted sequences over a broad range of viruses, and we present some theoretical considerations concerning insert stability. Different virus genome organizations strongly impact insert stability, and factors such as the position of insertion can have a strong effect. In addition, we argue that insert stability not only depends on the characteristics of a particular genome, but that it will also depend on the host environment and the demography of a virus population. -
A Systematic Review of Human Pathogens Carried by the Housefly
Khamesipour et al. BMC Public Health (2018) 18:1049 https://doi.org/10.1186/s12889-018-5934-3 REVIEWARTICLE Open Access A systematic review of human pathogens carried by the housefly (Musca domestica L.) Faham Khamesipour1,2* , Kamran Bagheri Lankarani1, Behnam Honarvar1 and Tebit Emmanuel Kwenti3,4 Abstract Background: The synanthropic house fly, Musca domestica (Diptera: Muscidae), is a mechanical vector of pathogens (bacteria, fungi, viruses, and parasites), some of which cause serious diseases in humans and domestic animals. In the present study, a systematic review was done on the types and prevalence of human pathogens carried by the house fly. Methods: Major health-related electronic databases including PubMed, PubMed Central, Google Scholar, and Science Direct were searched (Last update 31/11/2017) for relevant literature on pathogens that have been isolated from the house fly. Results: Of the 1718 titles produced by bibliographic search, 99 were included in the review. Among the titles included, 69, 15, 3, 4, 1 and 7 described bacterial, fungi, bacteria+fungi, parasites, parasite+bacteria, and viral pathogens, respectively. Most of the house flies were captured in/around human habitation and animal farms. Pathogens were frequently isolated from body surfaces of the flies. Over 130 pathogens, predominantly bacteria (including some serious and life-threatening species) were identified from the house flies. Numerous publications also reported antimicrobial resistant bacteria and fungi isolated from house flies. Conclusions: This review showed that house flies carry a large number of pathogens which can cause serious infections in humans and animals. More studies are needed to identify new pathogens carried by the house fly. -

ABSTRACT This report of a Technical Panel of the U.S. Environmental Protection Agency (EPA) RIsk Assessment Forum describes conditions under which the Forum advises EPA risk assessors against using information on certain renal tUbule tumors or nephrotoxicity to assess human risk. Risk assessment approaches generally assume that chemicals producing tumors in laboratory animals are a potential cancer hazard to humans. For most chemicals, including many rodent kidney carcinogens, this extrapolation remains appropriate. -

Viruses Virus Diseases Poaceae(Gramineae)
Viruses and virus diseases of Poaceae (Gramineae) Viruses The Poaceae are one of the most important plant families in terms of the number of species, worldwide distribution, ecosystems and as ingredients of human and animal food. It is not surprising that they support many parasites including and more than 100 severely pathogenic virus species, of which new ones are being virus diseases regularly described. This book results from the contributions of 150 well-known specialists and presents of for the first time an in-depth look at all the viruses (including the retrotransposons) Poaceae(Gramineae) infesting one plant family. Ta xonomic and agronomic descriptions of the Poaceae are presented, followed by data on molecular and biological characteristics of the viruses and descriptions up to species level. Virus diseases of field grasses (barley, maize, rice, rye, sorghum, sugarcane, triticale and wheats), forage, ornamental, aromatic, wild and lawn Gramineae are largely described and illustrated (32 colour plates). A detailed index Sciences de la vie e) of viruses and taxonomic lists will help readers in their search for information. Foreworded by Marc Van Regenmortel, this book is essential for anyone with an interest in plant pathology especially plant virology, entomology, breeding minea and forecasting. Agronomists will also find this book invaluable. ra The book was coordinated by Hervé Lapierre, previously a researcher at the Institut H. Lapierre, P.-A.
