Reactive torque influence onto rotation of comet nuclei. [PDF]

, 2002
: Reactive torques, due to anisotropic sublimation on a comet nucleus surface, produce slow variations of its rotation. In this paper the secular effects of this sublimation are studied.

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

Journal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

Observational constraints on surface characteristics of comet nuclei

, 2002
Direct observations of the nuclear surfaces of comets have been difficult; however a growing number of studies are overcoming observational challenges and yielding new information on cometary surfaces. In this review, we focus on recent determinations of

Oral Delivery of Bioencapsulated CTB‐Pro‐IGF‐1 Enhances Bone Regeneration in a Pre‐Clinical Rat Model of Jaw Osteoradionecrosis

Oral Diseases, EarlyView.
ABSTRACT Objective Head and neck cancer radiotherapy can lead to jaw osteoradionecrosis (ORN). There is currently no definitive treatment for ORN. The efficacy of a novel orally delivered aglycosylated IGF‐1 with an E‐peptide (CTB‐Pro‐IGF‐1), bioencapsulated in plant cells, was evaluated as therapy for jaw ORN in rats. Materials and Methods Rat jaw ORN

Baroclinic Vortex Generation by a Comet Shoemaker-Levy 9 Impact

, 1997
"Impact of Shoemaker-Levy 9 caused various changes on Jupiter. One of them is the comet impact sites left on the surface of Jupiter. These impact sites were very stable and long-1ived, which is a mystery worthy for detailed investigation.

Atmospheric ice nuclei in the Eyjafjallajökull volcanic ash plume [PDF]

, 2011
Explosive volcanism affects weather and climate. Primary volcanic ash particles which act as ice nuclei (IN) can modify the phase and properties of cold tropospheric clouds.

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Comet nuclei primordial aggregation effects on their internal structure

, 2009
Comet nuclei have a low density ( 500 kg.m-3, e.g. [1]) and are easily disrupted. In situ studies have unveiled surface features hinting at a pervasive internal layered structure on 9P/Tempel 1 [2].
