Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Types, characteristics, origin and exploration significance of reef-shoal reservoirs: A case study of Tarim Basin, NW China and Sichuan Basin, SW China

open access: yesPetroleum Exploration and Development, 2014
Taking reef-shoal bodies developed in multiple formations in the Tarim and Sichuan Basins as examples, this paper examines the origin of pores and heterogeneity of different types of reef-shoal reservoirs, and tries to find out the distribution rules of ...

The Role of Small Reservoirs in Reducing Reactive N Export Via Denitrification [PDF]

open access: yes, 2019
Reactive nitrogen (N), which harms ecosystem health, has been increasing in the biosphere, leading to higher N export to coastal ecosystems. Although man-made reservoirs can be significant sources of greenhouse gases, they can also retain N, thus ...

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Study on the vertical well seepage model in composite carbonate reservoirs

open access: yesFrontiers in Earth Science, 2023
Introduction: Carbonate reservoirs are widely distributed throughout the world. Due to the good physical properties of the reservoirs, they are easily contaminated by mud during drilling opening, so they are often put into production after acidification.

Effects of Water Released From Stratified and Unstratified Reservoirs on the Downstream Water Quality [PDF]

open access: yes, 1982
Water quality samples were collected from the Little River system in Pine Creek Lake, Oklahoma, and Gillham Lake, Arkansas, and their associated tailwaters during the winter (reservoirs unstratified) and summer (reservoirs stratified) of 1980. Downstream

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
