The multiple roles of the NlpC_P60 peptidase family in mycobacteria – an underexplored target for antimicrobial drug discovery

open access: yesFEBS Letters, EarlyView.
The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Review of the species of Stenothemus from Southeast China (Coleoptera, Cantharidae)

open access: yesEuropean Journal of Taxonomy, 2021
The species of Stenothemus Bourgeois, 1907 from Southeast China are reviewed. Stenothemus fukienensis Wittmer, 1974 and S. kuatunensis Wittmer, 1979 are supplementarily described. Two new species are described, S. longicornis Y. Yang & H. Liu sp.

A NEW SPECIES OF OLIGOLOPHUS [PDF]

open access: yesThe Canadian Entomologist, 1893
Very few Phalangids have been collected on our mountains, and so it is not surprising that a new species of a genus which in Europe lives in high altitudes should be found on Mt. Washington, New Hampshire. Early in September 1893, Mrs. Annie T. Slosson kindly sent me several vials of arachnids from the White Mts., and among them o vial from Mt ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms

open access: yesFEBS Letters, EarlyView.
Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

Interplay of spatial dynamics and local adaptation shapes species lifetime distributions and species-area relationships [PDF]

open access: yes, 2018
The distributions of species lifetimes and species in space are related, since species with good local survival chances have more time to colonize new habitats and species inhabiting large areas have higher chances to survive local disturbances. Yet, both distributions have been discussed in mostly separate communities.

Species-to-species rate coefficients for the $\rm H_3^+ + H_2$ reacting system [PDF]

open access: yesA&A 607, A26 (2017), 2017
Aims. We study whether rotational excitation makes a difference to the abundances of the $\rm H_3^+$ isotopologs, including spin states, in physical conditions corresponding to starless cores and protostellar envelopes. Methods. We developed a new rate coefficient set for the $\rm H_3^+$ isotopologs, allowing for rotational excitation, using the ...

A NEW SPECIES OF AEGIALITES [PDF]

open access: yesThe Canadian Entomologist, 1898
During his visit in 1896 to Robben Island, a low rock only 2,000 feet long, situated near the eastern coast of Sakhalin Island, in Okhotsk Sea, Dr. Leonhard Stejneger collected only two species of insects, both Coleoptera. One of them is a species of Bembidium, possibly new, but it should be compared with the numerous species from the mainland, which ...
