From cloning to mutant in 5 days: rapid allelic exchange in .

Access Microbiol 2021 Feb 7;3(2):000193. Epub 2021 Jan 7.

Department of Microbiology and Immunology, The University of Melbourne at the Peter Doherty Institute for Infection & Immunity, Melbourne, Victoria, Australia.

In the last 10 years, the barriers preventing the uptake of foreign DNA by clinical isolates have been identified and powerful mutagenesis techniques such as allelic exchange are now possible in most genotypes. However, these targeted approaches can still be cumbersome, and the construction of unmarked deletions/point mutations may take many weeks or months. Here, we introduce a streamlined allelic exchange protocol using IMxxB and the plasmid pIMAY-Z. Read More

Front Oncol 2021 3;11:656851. Epub 2021 Jun 3.

CEDOC, Chronic Diseases Research Centre, NOVA Medical School|Faculdade de Ciências Médicas, Universidade NOVA de Lisboa, Lisboa, Portugal.

Metastasis is a major hurdle to the efficient treatment of cancer, accounting for the great majority of cancer-related deaths. Although several studies have disclosed the detailed mechanisms underlying primary tumor formation, the emergence of metastatic disease remains poorly understood. This multistep process encompasses the dissemination of cancer cells to distant organs, followed by their adaptation to foreign microenvironments and establishment in secondary tumors. Read More

Developmental Features of Lexical Richness in English Writings by Chinese Beginner Learners.

Front Psychol 2021 2;12:665988. Epub 2021 Jun 2.

School of Foreign Languages, Northeast Normal University, Changchun, China.

This paper reports a cross-sectional study that investigates the developmental features in second language writings by Chinese beginner learners of English by using four lexical richness measures-lexical sophistication, lexical variation, lexical density, and lexical errors-from the perspective of the language exposure hypothesis. Specifically, the study compares English compositions written by Chinese students of grade 7, grade 8, and grade 9 in terms of lexical sophistication, lexical variation, lexical density, and lexical errors. The English compositions were sampled from the Writing Corpus of Chinese Beginner Learners of English, and the sample size of the three grades remained almost the same. Read More

Second Language Learning in Older Adults: Effects on Brain Structure and Predictors of Learning Success.

Front Aging Neurosci 2021 3;13:666851. Epub 2021 Jun 3.

Aging Research Center, Karolinska Institute (KI), Stockholm University, Stockholm, Sweden.

It has previously been demonstrated that short-term foreign language learning can lead to structural brain changes in younger adults. Experience-dependent brain plasticity is known to be possible also in older age, but the specific effect of foreign language learning on brain structure in language-and memory-relevant regions in the old brain remains unknown. In the present study, 160 older Swedish adults (65-75 years) were randomized to complete either an entry-level Italian course or a relaxation course, both with a total duration of 11 weeks.

Native Language Similarity during Foreign Language Learning: Effects of Cognitive Strategies and Affective States.

Appl Linguist 2021 Jun 10;42(3):514-540. Epub 2020 Oct 10.

Northwestern University, Evanston, IL, 60208, USA.

According to the US Department of State, a native English speaker can learn Spanish in about 600 h, but would take four times as long to learn Japanese. While it may be intuitive that similarity between a foreign language and a native tongue can influence the ease of acquisition, what is less obvious are the specific cognitive and emotional processes that can lead to different outcomes. Here, we explored the influence of cognitive strategies and affective states on native English speakers' ability to learn artificial foreign words that vary in their similarity to the native language.

Integrating international linguistic minorities in emergency planning at institutions of higher education.

Nat Hazards (Dordr) 2021 Jun 16:1-25. Epub 2021 Jun 16.

Florida Institute for Built Environment Resilience, University of Florida, Gainesville, FL USA.

Research concerning the behavior of international linguistic minorities at institutions of higher education during disasters is very limited. Many international groups suffer from discrimination based on language (linguicism) during disasters-their stories are not being told, and their voices are not being heard. The main objective of our study is to develop new knowledge about disaster-related behaviors of international linguistic minorities at institutions of higher education with a view toward enhancing overall campus emergency planning.

Household sampling through geocoded points and satellite view: A step-by-step approach to implement a spatial sampling method for demographic and health surveys in areas without population sampling frame and with limited resource settings.

Rev Epidemiol Sante Publique 2021 Jun 17. Epub 2021 Jun 17.

Institut de recherche pour le développement/Development research institute, Unité mixte de recherche 216/Mixed research unit 216: Mères et enfants face aux infections tropicale/Mother and child face to tropical infection, Faculté de pharmacie Paris-Descartes, 4, avenue de l'observatoire, 75006 Paris, France. Electronic address:

Introduction: Spatial sampling is increasingly used in health surveys as it provides a simple way to randomly select target populations on sites where reliable and complete data on the general population are not available. However, the previously implemented protocols have been poorly detailed, making replication difficult or even impossible. To our knowledge, ours is the first document describing step-by-step an efficient spatial sampling method for health surveys. Read More

Contributions of PD-L1 reverse signaling to dendritic cell trafficking.

FEBS J 2021 Jun 19. Epub 2021 Jun 19.

Department of Medicine, Division of Gastroenterology and Hepatology, University of Colorado School of Medicine Aurora, CO, USA.

Programmed Death-1 (PD-1)/Programmed Death-Ligand 1 (PD-L1) interactions are critical for dampening the immune response to both self and foreign antigens. The signaling of PD-L1 via its cytoplasmic domain, rather than through its interactions with PD-1 via the extracellular domain, has been termed PD-L1 reverse signaling. While this signaling is beneficial for cancer progression, little is understood about the consequences of PD-L1 reverse signaling in immune cells that express PD-L1 at steady state or in response to infection.

Harmony Between Humanity and Nature: Natural Vs. Synthetic Drug Preference in Chinese Atheists and Taoists.

Yu Cao Heng Li

J Relig Health 2021 Jun 19. Epub 2021 Jun 19.

College of International Studies, Southwest University, Tianshengqiao Road, Beibei, Chongqing, China.

A commonplace observation across many cultures is that humans show a strong preference for natural items on drug choice in the medical domain. Despite an emerging line of psychological research on individual differences in the naturalness-is-better bias, few studies have focused on the role of religious beliefs. According to the core idea of Taoism, people should free themselves from selfishness and desire and behave in concert with the alternating cycles of Nature. Read More

Chimeric virus-like particles of universal antigen epitopes of coronavirus and phage Qβ coat protein trigger the production of neutralizing antibodies.

Curr Top Med Chem 2021 Jun 18. Epub 2021 Jun 18.

College of Veterinary Medicine, Henan Agricultural University, Zhengzhou 450046, China; b Key Laboratory of Animal Biochemistry and Nutrition, Ministry of Agriculture and Rural Affairs, Henan Agricultural University, Zhengzhou 450046, China.

Background: Virus-like particles (VLPs) are non-genetic multimeric nanoparticles synthesized through in vitro or in vivo self-assembly of one or more viral structural proteins. Immunogenicity and safety of VLPs make them ideal candidates for vaccine development and efficient nanocarriers for foreign antigens or adjuvants to activate the immune system.
