Charge-Transfer Probes for Molecular Recognition \u3cem\u3evia\u3c/em\u3e Steric Hindrance in Donor-Acceptor Pairs [PDF]

open access: yes, 1997
Molecular association of various aromatic hydrocarbons (D, including sterically hindered donors) with a representative group of diverse acceptors (A = quinone, trinitrobenzene, tetracyanoethylene, tropylium, tetranitromethane, and nitrosonium) is ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Assemblage of Bacteria Communities and Resistome Enrichment by Dairy Flurries Along the Rhizosphere–Bulk Soil Continuum on Dairy Farms

open access: yesAgronomy
The use of dairy slurries as organic fertilizer amendments is a common practice in agriculture as a cost-saving measure, as well as a residue management strategy. However, concerns related to the increase in antibiotic resistance in the environment under

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

open access: yesInsect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

Neoclassical development of genetic sexing strains for insect pest and disease vector control

open access: yesInsect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

Harnessing iEcology data to uncover invasive species behaviour

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Invasive animal species threaten ecosystems, biodiversity and human livelihoods. Behavioural traits such as boldness, exploratory tendencies, learning ability and social interactions are known to influence invasion success. Yet these behavioural traits remain underexplored due to challenges in observing behaviour across large spatial and ...

Incidence of Gonadal and Extragonadal Germ Cell Tumours in Patients With Klinefelter Syndrome

open access: yesAndrology, EarlyView.
ABSTRACT Background Klinefelter's syndrome (KS; 47, XXY) is associated with an altered risk profile for malignancies compared with non‐KS males. In particular, several reports have noted a striking association between KS and extragonadal germ cell tumours (EGCTs), especially in the mediastinum, whereas the risk of testicular germ cell tumours (TGCTs ...

Emergence and genomic epidemiology of tigecycline resistant bacteria of fly origin across urban and rural China

open access: yesEnvironment International
Plasmid-mediated tigecycline resistance genes, notably the tet(X) and tmexCD-toprJ genes, have garnered considerable attention due to their transferability.
