New ichnological findings in Hauterivian sandstones of Mountainous Adygeya

open access: yesИзвестия высших учебных заведений: Геология и разведка
Background. Trace fossils are highly informative objects for geological investigations. However, the information about their distribution in sedimentary settings lacks completeness.

The Role of Sediment and Sediment Dynamics in the Aquatic Environment

open access: yes, 2018
The dynamic component in hydrology, sedimentology, and, consequently, river morphology serves as a backbone for the entire river environment (Maddock 1999). In addition to water pollution, the hydro-morphological/sedimentological degradation is one of the main pressures on river systems (Ward and Stanford 1995; Dudgeon et al. 2006).

Modeling hydrography and marine sedimentation in the Cariaco Basin since the Last Glacial Maximum

open access: yes, 2009
The Cariaco Basin has shallow connections with the Caribbean Sea, and these are further reduced at times of lower sea level, such as at the Last Glacial Maximum (LGM).

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Microfacies and foraminifers of the Tulian horizon (the Visean substage, Lower Carboniferous) of the southeast of the East European platform and the Southern Urals

open access: yesGeoresursy
The article presents the characteristics of microfacies and foraminiferal complexes of the Tulian horizon of the Visean substage in sections of the Preduralskaya-106 and Oktyabrskaya-106 boreholes in the Eastern part of the Volga-Ural region and the ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Paleo-environments of sedimentation, mud volcanism and hydrocarbons migration in the South-Caspian basin

open access: yesГеофизический журнал, 2020
One of the problems of oil and gas geology, not finally solved, is a mechanism of hydrocarbons migration and oil and gas deposits formation. It is well known that for production of deposits the presence of not only parent rocks, rocks-collectors and roof-

Sedimentary processes in the Thau Lagoon (France): From seasonal to century time scales [PDF]

open access: yes, 2007
As a part of the MICROBENT programme, an investigation of the sedimentation framework was carried out at the water-sediment interface in the Thau Lagoon (French Mediterranean coast). Two main sites, C4 in the middle of the lagoon and C5 near oyster farms,

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
