Radar Perspective of the Aristarchus Pyroclastic Deposit and Implications for Future Missions

The Planetary Science Journal, 2023
The Aristarchus plateau represents one of the most complex volcanic provinces on the lunar surface and is host to the largest pyroclastic deposit on the Moon.

Recent Tectonic Deformation of the Lunar Farside Mare and South Pole–Aitken Basin

The Planetary Science Journal
The timing and scale of lunar tectonism provide a crucial insight into the geologic evolution of Earth’s Moon. Within the nearside lunar maria, wrinkle ridges formed during and after the emplacement of the mare basalts as a result of subsidence-induced ...

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

The Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.

A New Global Perspective on Recent Tectonism in the Lunar Maria

The Planetary Science Journal
Earth’s Moon exhibits evidence that it is tectonically active. That evidence includes the Apollo Lunar Seismic Experiment detection of shallow moonquakes and the presence of geologically young tectonic features at the lunar surface. Lobate scarps are one

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

The Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Lunar Boulder Fields as Indicators of Recent Tectonic Activity

The Planetary Science Journal
Wrinkle ridges are the predominant tectonic structure on the nearside lunar maria. Although lunar wrinkle ridge formation began as early as ∼3.9–4.0 Ga, recent investigations have identified wrinkle ridges in the lunar maria that were tectonically active

New Observations of Recently Active Wrinkle Ridges in the Lunar Mare: Implications for the Timing and Origin of Lunar Tectonics

Geophysical Research Letters, 2022
The variety of tectonic features on the Moon indicates that the lunar lithosphere has undergone a complex deformational history. Lobate scarps and wrinkle ridges are two such tectonic features that have resulted from compressional stresses.

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK Pathways

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

Unveiling Basalt Distribution of Lunar Cryptomaria from Gravity and Topography when Considering the Effect of Surface Cover-layer and Density Correction

The Astronomical Journal
The cryptomaria preserves critical evidence of early lunar volcanism and thermal evolution, offering key constraints on the Moon’s internal heat flow and mantle melting processes.

On the equipotential surface hypothesis of lunar maria floors [PDF]

Journal of Geophysical Research: Planets, 1999
The equipotential surface hypothesis suggests that lunar maria floors lie on a surface parallel to the selenoid. This is examined using the spherical harmonic representations of the Clementine topography and Lunar Prospector gravity data. It is demonstrated that the floors of both circular and noncircular maria significantly deviate from an ...
