Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

open access: yesIntegrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Mechanisms of Mitochondrial Toxicity and Cytotoxicity Caused by Pseudomonas aeruginosa Pyocyanin in Human Nasal Epithelial Cells

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Pseudomonas aeruginosa is an opportunistic pathogen in cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) that produces phenazine metabolites pyocyanin and 1‐hydroxyphenazine (1‐HP), which may have detrimental effects on mitochondria, reactive oxygen species (ROS), Ca2+ signaling, and apoptosis.

Boron deficiency responses in maize (Zea mays L.) roots

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Adenovirus Vectors Target Several Cell Subtypes of Mammalian Inner Ear In Vivo

open access: yesNeural Plasticity, 2016
Mammalian inner ear harbors diverse cell types that are essential for hearing and balance. Adenovirus is one of the major vectors to deliver genes into the inner ear for functional studies and hair cell regeneration.

Hochdrucksynthese von Antimonnitrid Sb3N5 und Polynitrid Sb2N8 mit einfach gebundenen N810− Ketten

open access: yesAngewandte Chemie, EarlyView.
Hochdrucksynthesen zwischen Antimon und molekularem Stickstoff in einer laserbeheizten Diamantstempelzelle führten zur Bildung von oC32‐Sb3N5 (51(1) GPa) und mP20‐Sb2(N8) (> 100 GPa). Beide Phasen wurden mittels Einkristall‐Röntgenmikrodiffraktion identifiziert und durch Berechnungen mittels Dichtefunktionaltheorie vollständig bestätigt.

Rational Design of Inner Ear Drug Delivery Systems

open access: yesAdvanced Science
The number of people with hearing loss disorders is enormous, causing great physical and mental stress to patients, as well as a huge social burden. Among these patients, hearing loss caused by inner ear lesions accounts for a large proportion. Therefore,

High‐Pressure Synthesis of Antimony Nitride Sb3N5 and Polynitride Sb2N8 Featuring Single‐Bonded N810− Chains

open access: yesAngewandte Chemie International Edition, EarlyView.
High‐pressure reactions between Sb and molecular nitrogen in a laser‐heated diamond anvil cell led to the formation of oC32‐Sb3N5 (51(1) GPa) and mP20‐Sb2(N8), (> 100 GPa). Both phases were identified by single‐crystal x‐ray microdiffraction and are fully corroborated by density functional theory calculations.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

open access: yesThe Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

open access: yesThe Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

open access: yesThe Anatomical Record, EarlyView.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...
