Functional traits mediate individualistic species‐environment distributions at broad spatial scales while fine‐scale species associations remain unpredictable

open access: yesAmerican Journal of Botany, Volume 109, Issue 12, Page 1991-2005, December 2022., 2022
Abstract Premise Numerous processes influence plant distributions and co‐occurrence patterns, including ecological sorting, limiting similarity, and stochastic effects. To discriminate among these processes and determine the spatial scales at which they operate, we investigated how functional traits and phylogenetic relatedness influence the ...

Sex bias in Neolithic megalithic burials

open access: yesAmerican Journal of Biological Anthropology, Volume 180, Issue 1, Page 196-206, January 2023., 2023
Abstract Objectives A statistical study comparing osteological and ancient DNA determinations of sex was conducted in order to investigate whether there are sex biases in United Kingdom and Irish Neolithic megalithic burials. Materials and Methods Genetic and osteological information from human individuals from 32 megalithic sites in the UK and Ireland

Efficacy of the exhalation delivery system with fluticasone in patients with chronic rhinosinusitis with nasal polyps whose symptoms recur after sinus surgery

open access: yesInternational Forum of Allergy &Rhinology, Volume 13, Issue 1, Page 31-41, January 2023., 2023
Abstract Background Sinus surgery removes inflamed tissue, restores airflow, and improves delivery of medication into surgically opened spaces. The exhalation delivery system with fluticasone (EDS‐FLU; XHANCE®) uses a novel delivery system to create closed‐palate, positive‐pressure, bidirectional mechanics that significantly alter the deposition of the

Predicting Collagen Triple Helix Stability through Additive Effects of Terminal Residues and Caps

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
Collagen model peptides are like a construction set. The stability of collagen triple helices is critically determined by the frame, terminal residues, capping groups, and their charge state. The effects are additive and can be used to predict the melting temperatures of new collagen trimers.

Genetic population structure of the critically endangered stellate sturgeon (Acipenser stellatus) in the Black Sea basin: Implications for conservation

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1926-1939, December 2022., 2022
Abstract Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced a dramatic decline in abundance and distribution in the Black Sea basin. Information regarding the genetic structure of the species is very limited in the region, despite its crucial importance for ...

Multi‐omics analyses reveal the interaction between colonic microbiota and host in Min and Yorkshire pigs

open access: yesAnimal Research and One Health, EarlyView., 2023
In the present study, we created the weight gain models with Min and Yorkshire pigs and conducted the metagenomics and metabolomics of colon contents and transcriptomics of colon tissue. Further, we revealed the characteristics and functions of the colonic microbiota in Min and Yorkshire pigs and analyzed their interactions with the host. Overall, this

Spexin in the European sea bass, Dicentrarchus labrax: Characterization, brain distribution, and interaction with Gnrh and Gnih neurons

open access: yesJournal of Comparative Neurology, Volume 531, Issue 2, Page 314-335, February 2023., 2023
The main objective of this work was to obtain detailed information on the distribution and localization of the spexin (Spx) system in the sea bass brain. To this purpose, we first identified and characterized the spx1 gene and analyzed its expression in the central nervous system (CNS) of the European sea bass by using quantitative Real‐Time Polymerase

N and P constrain C in ecosystems under climate change: Role of nutrient redistribution, accumulation, and stoichiometry

open access: yesEcological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract We use the Multiple Element Limitation (MEL) model to examine responses of 12 ecosystems to elevated carbon dioxide (CO2), warming, and 20% decreases or increases in precipitation. Ecosystems respond synergistically to elevated CO2, warming, and decreased precipitation combined because higher water‐use efficiency with elevated CO2 and higher ...

Ultrafast Room‐Temperature Nanofabrication via Ozone‐Based Gas‐Phase Metal‐Assisted Chemical Etching for High‐Performance Silicon Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Decoding Directional Control in Metal‐Assisted Chemical Etching via Catalyst Architecture

open access: yesAdvanced Materials, EarlyView.
Metal‐assisted chemical etching (MaCE) enables silicon nanostructure fabrication but suffers from isotropic undercutting. This study highlights the critical role of catalyst morphology in etching directionality. High‐aspect‐ratio catalysts induce lateral etching, while thermal treatment at 450 °C stabilizes catalyst geometry, promoting vertical etching.
