Management of Absent Upper Esophageal Sphincter Opening After Neurological Injury

open access: yesThe Laryngoscope, EarlyView.
This study evaluated the effects of swallowing therapy and cricopharyngeus (CP) muscle surgery on upper esophageal sphincter (UES) opening, oral intake, and airway protection in patients with absent UES opening following neurological injury. CP‐targeted surgeries were associated with improved bolus passage and oral intake, but persistent aspiration ...

Iron/Manganese Oxide‐Bound Nitrogen Suppresses Microbial Mediated Nitrate Reduction in Soil

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Nitrogen cycling plays a pivotal role in sustaining ecosystem productivity and stability, while the chemical forms of nitrogen in soils critically influence both its efficiency and pathways. In this study, farmland soils from the Anning River Basin—an important watershed in Southwest China—were investigated to examine the regulatory effects of

Higher NO3−‐N Levels Under Mulberry (Morus alba L.) Planting Enhanced CAZyme Abundance, Increasing Soil Carbon Stability

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Afforestation is widely advocated for boosting carbon (C) sequestration. However, the stability of soil C pools in economically and culturally significant mulberry plantations remains poorly understood. The soil organic C (SOC) contents in different aggregates and the oxidizable OC fractions were measured.

Seasonal Dynamics of Soil Multitrophic Biodiversity, Co‐Occurrence Network and Assembly Mechanisms Under Typical Vegetation Restoration Patterns in Karst Region

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Previous studies often overlooked the dynamic effects of karst vegetation restoration on soil multi‐trophic biodiversity and the underlying community‐assembly mechanisms. To fill this gap, we performed a seasonal comparative analysis of soil biodiversity, co‐occurrence network architecture, and assembly processes across three representative ...

Sodium sulfite can reliably induce chemical hypoxia without toxic effects in the model sea anemone species, Exaiptasia diaphana

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Climate change is accelerating the deoxygenation of aquatic ecosystems, so understanding its effects on biological processes is increasingly critical. An emerging method for inducing hypoxia during experimentation utilizes sodium sulfite (SSI) to scavenge oxygen; however, it remains unclear if hypoxia‐inducing concentrations of SSI are toxic ...

Ascorbate-glutathione cycle in wheat and rice seedlings under anoxia and subsequent reaeration

open access: yesВавиловский журнал генетики и селекции
The most important part of the plant antioxidant system is the ascorbate-glutathione cycle (AGC), the activity of which is observed upon exposure to a range of stressors, including lack of O2, and oxidative stress occurring immediately after the ...

NITRIC OXIDE (NO), CITRULLINE - NO CYCLE ENZYMES, GLUTAMINE SYNTHETASE AND OXIDATIVE STRESS IN ANOXIA (HYPOBARIC HYPOXIA) AND REPERFUSION IN RAT BRAIN

open access: yesInternational Journal of Medical Sciences, 2010
Nitric oxide is postulated to be involved in the pathophysiology of neurological disorders due to hypoxia/ anoxia in brain due to increased release of glutamate and activation of N-methyl-D-aspartate receptors.

Improved Corrosion Resistance of a Micro‐Alloyed Carbon Steel Assessed by Multi‐Element Electrical Resistance Probes and Coupons in Natural Seawater and Soil

open access: yesMaterials and Corrosion, EarlyView.
Multi‐element electrical resistance probes fabricated from industrial carbon steels enable real‐time corrosion monitoring in natural seawater and soil. A micro‐alloyed grade (AMLoCor) demonstrates up to 2.4 times improved uniform corrosion resistance over conventional S355 GP steel.

Beyond Bioenergetics: Moonlighting Functions of F1FO‐ATPase From ATP Synthesis to an ATP‐Wasting Death Switch

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Mitochondrial F1FO‐ATPase is classically viewed as the “splendid” rotary nanomachine that sustains life by converting the proton‐motive force (pmf) into ATP. Yet this same complex can adopt a second, context‐dependent function that links bioenergetics to cell fate.
