Construction of a bicistronic vector for the co-expression of two genes in Caenorhabditis elegans using a newly identified IRES

open access: yesBioTechniques, 2012
The nematode Caenorhabditis elegans is an important model animal for biological research. Currently, transgenic C. elegans strains are mainly generated by injecting DNA encoding a gene of interest, in combination with a reporter gene, into the gonad ...

Periacineta mexicana n. sp. (Ciliophora, Suctoria, Discophryida), Epizoic on Mexican Backswimmers of the Genus Buenoa (Insecta, Hemiptera, Notonectidae) [PDF]

open access: yes, 2010
A new species of suctorian in the genus Periacineta, epibiotic on aquatic bugs (Hemiptera, Heteroptera, Nepomorpha), is described on the basis of morphological characteristics of the cell body, lorica, tentacular placement, and stalk, and its 18S rRNA ...

Effect of Spiroplasma infection on the mating behavior of Glossina fuscipes fuscipes

open access: yesInsect Science, EarlyView.
Abstract Tsetse flies are insects of significant public health and zoonotic importance as they are the main vectors of African trypanosomes. To date, an effective vaccine is unavailable and efforts to limit the spread of the disease primarily rely on controlling the tsetse populations.

Antony van Leeuwenhoek: Creation “Magnified” Through His Magnificent Microscopes [PDF]

open access: yes, 2012
Although van Leeuwenhoek was not the inventor of the microscope, he advanced it more than anyone else for seeing living things. Antony van Leeuwenhoek1 (Fig. 1) found great joy in God’s smallest creatures. He first discovered protozoans in his youth. The

Stress in dipteran insects mass‐reared for sterile insect technique applications

open access: yesInsect Science, EarlyView.
The connections between biotic and abiotic stress affecting mass‐reared dipteran insects and the associated stress and immunological responses. Numbers indicate the order in which the topics are discussed in this review. Abstract Stress may be viewed as the disturbance of homeostasis of an organism.

Sensitive detection systems for infectious agents in xenotransplantation*

open access: yesXenotransplantation, EarlyView., 2020
Abstract Xenotransplantation of pig cells, tissues, or organs may be associated with transmission of porcine microorganisms, first of all of viruses, to the transplant recipient, potentially inducing a disease (zoonosis). I would like to define detection systems as the complex of sample generation, sample preparation, sample origin, time of sampling ...

Urban landscapes tend to increase the presence of pathogenic protozoa, microsporidia and viruses, but likely decrease the abundance of viruses in wild bees and wasps

open access: yesInsect Science, EarlyView.
• The bees Anthophora plumipes and Osmia cornuta had a higher occurrence probability of the neogregarine protozoan Apicystis bombi in more fragmented urban areas.• In the bee Halictus scabiosae and wasp Polistes dominula, hotter urban areas increased the likelihood of occurrence of viruses.• The viruses were found to be replicative in the samples, and ...

A minimum principle in mRNA editing ?

open access: yes, 2001
mRNA editing of sequences of many species is analyzed. The nature of the inserted nucleotides and the position of the insertion sites, once fixed the edited peptide chain, are explained by introducing a minimum principle in the framework of the crystal ...
