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

open access: yesThe 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.

The Faustini Permanently Shadowed Region on the Moon

open access: yesThe Planetary Science Journal
Faustini crater (41 km diameter) hosts a large (664 km ^2 ) permanently shadowed region (PSR) with a high potential to harbor water-ice deposits. One of the 13 candidate Artemis III landing areas contains a portion of the crater rim and proximal ejecta ...

Coupling Complementary Strategy to U-Net Based Convolution Neural Network for Detecting Lunar Impact Craters

open access: yesRemote Sensing, 2022
Lunar crater detection plays an important role in lunar exploration, while machine learning (ML) exhibits promising advantages in the field. However, previous ML works almost all used a single type of lunar map, such as an elevation map (DEM) or ...

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

open access: yesThe 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

Illumination Model of Lunar Terrain around Lunar Laser Retroreflectors Based on LOLA Data

open access: yesRemote Sensing
Lunar laser retroreflectors are a crucial target for lunar laser ranging (LLR). During LLR operations at all lunar laser ranging stations, the considerable distance between the Earth and the Moon makes it impossible to visually identify the position of ...

Primordial black hole detection through diffractive microlensing

open access: yes, 2018
Recent observations of gravitational waves motivate investigations for the existence of Primordial Black Holes (PBHs). We propose the observation of gravitational microlensing of distant quasars for the range of infrared to the submillimeter wavelengths ...

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

open access: yesArthritis &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.

A New Global Perspective on Recent Tectonism in the Lunar Maria

open access: yesThe 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
