On the Early Thermal Processing of Planetesimals during and after the Giant Planet Instability

The Planetary Science Journal
Born as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets’ dynamical instability in the early stages of our solar system’s history.

Muon-to-electron conversion in mirror fermion model with electroweak scale non-sterile right-handed neutrinos

Nuclear Physics B, 2018
The muon-to-electron conversion in aluminum, titanium and gold nuclei is studied in the context of a class of mirror fermion model with non-sterile right-handed neutrinos having masses at the electroweak scale.

Goniothalamin as a Styryl‐Lactone Toxicophore in Cancer Models: Electrophile‐Driven DNA Damage, Reactive Oxygen Species–Endoplasmic Reticulum Stress Signaling and Detoxification‐Relevant Safety Considerations

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
Goniothalamin (GTN) exerts anticancer effects by promoting reactive oxygen species (ROS) generation, glutathione (GSH) depletion, DNA damage, endoplasmic reticulum (ER) stress, and mitochondrial dysfunction. These interconnected events trigger apoptosis, necroptosis, anoikis, and autophagy, while modulating mitogen‐activated protein kinase (MAPK ...

Mycoplasma bovis involved in pituitary abscess syndrome in a beef heifer concomitantly infected with haemoparasites

Veterinary Record Case Reports, Volume 14, Issue 3, August 2026.
Abstract This case report describes pituitary abscess syndrome (PAS) in a 20‐month‐old Blonde d'Aquitaine heifer with cranial nerve deficits (V, VII, VIII, IX, X and XII) associated with facial hemiparesis, head tilt, ataxia and dysphagia, pneumonia and otitis interna.

Mechanistic Study of Platelet Membrane‐Coated Resveratrol Nanosystem in Mitochondrial Dysfunction and Endothelial Senescence During Atherosclerotic Lesion Development via FOXM1 Activation

Aging Cell, Volume 25, Issue 8, August 2026.
Schematic diagram of the mechanism by which PM@RSV NPs alleviate AS via FOXM1 activation. ABSTRACT Atherosclerosis (AS) is closely linked to endothelial cell (EC) senescence and mitochondrial dysfunction, which impair vascular repair. Resveratrol (RSV) has antioxidant, anti‐inflammatory, and pro‐angiogenic effects, but its clinical use is restricted by

Physical Properties of Frozen Volatiles—Their Relevance to the Study of Comet Nuclei [PDF]

International Astronomical Union Colloquium, 1989
AbstractThe structural and thermodynamical properties of water ice and ice mixtures containing CO, CO2, CH4, and NH3 are thought to be important for the evolution of cometary nuclei. Based on recent laboratory studies performed by several groups, an overview is given of the properties of various ices condensed at low temperatures and of their evolution

Primary cardiac T‐cell rich large B‐cell lymphoma causing aortic stenosis with metastasis in a Warmblood

Equine Veterinary Education, Volume 38, Issue 8, Page e488-e495, August 2026.
Summary An 18‐year‐old Warmblood mare was presented to the Royal Veterinary College Equine Referral Hospital for investigation of progressive periocular and facial swelling, weight loss and tachycardia. Physical examination additionally identified bilateral pansystolic (grade 5/6 basilar left‐sided, 2/6 right‐sided), cardiac murmurs, submandibular ...

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, Volume 20, Issue 7, Page 1814-1834, July 2026.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Chromosomal Instability Drives Glioblastoma Heterogeneity and Therapeutic Opportunities

Advanced Science, Volume 13, Issue 39, 13 July 2026.
ABSTRACT Glioblastoma, the most aggressive and lethal form of brain cancer, is defined by profound genomic instability, with Chromosomal Instability (CIN) playing a central role in driving tumor progression, therapy resistance, and poor prognosis. CIN is characterized by numerical and structural alterations, is driven by mechanisms such as mitotic ...

Dust and gas emission from cometary nuclei: the case of comet 67P/Churyumov–Gerasimenko

Advances in Physics: X, 2018
Comets display with decreasing solar distance an increased emission of gas and dust particles, leading to the formation of the coma and tail. Spacecraft missions provide insight into the temporal and spatial variations of the dust and gas sources located
