SPECIFIC FEATURES OF STRUCTURES IN THE INNER COMA OF COMET C/2017 T2 (PANSTARRS) AS OBSERVED WITH THE OMT-800 TELESCOPE OF THE ODESSA OBSERVATORY TELESCOPE NETWORK

Odessa Astronomical Publications, 2020
Observations of the comet were carried out using the OMT-800 telescope (the primary mirror diameter D = 80 cm; the focal length F = 214 cm) of the Odessa Observatory telescope network from January to June 2020.

The Pre-perihelion Evolution of the Activity of Comet C/2017 K2 (Pan-STARRS) during the Water Ice-line Crossover

The Astronomical Journal
Comets, relics from the early solar system, consist of dust and ice. The ice sublimates as comets approach the Sun, ejecting dust from their nuclei seen as activity.

Measuring Blood Plasma Glutamine Levels Using a Nanopore‐Based Sensor

Advanced Healthcare Materials, EarlyView.
Glutamine (GLN) is a biomarker useful for predicting toxic ammonia accumulation. Here, we used a biosensor based on the Cytolysin A (ClyA) nanopore coupled with the GLN‐specific protein substrate‐binding domain 2 (SBD2) to demonstrate real‐time measurement of GLN in blood plasma, highlighting the potential for future point‐of‐care applications ...

Fumarate Hydratase Lactylation Exacerbates Traumatic Brain Injury Pathology via Mitochondrial Dysfunction and Neuroinflammation

Advanced Science, EarlyView.
Tian et al. reveal that FH K112 lactylation is elevated after TBI, leading to fumarate accumulation, mitochondrial damage, mtDNA release and amplified neuroinflammation. AARS2 and SIRT3 act as the “writer” and “eraser” for FH K112 lactylation. The peptide Pep‐K112 targeting this site alleviates brain injury, highlighting a potential therapeutic target.

Coma morphology and dust emission pattern of comet C/2020 F3 (NEOWISE) [PDF]

, 2021
The recent close approach of comet C/2020 F3 (NEOWISE) allowed us to study the morphology of its inner coma. From the measurement of the dust ejection velocity on spiral structures expanding around the nucleus, we estimated a mean deprojected expansion ...

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

Advanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Cometary Comae-Surface Links [PDF]

Space Science Reviews, 2020
Abstract A comet is a highly dynamic object, undergoing a permanent state of change. These changes have to be carefully classified and considered according to their intrinsic temporal and spatial scales. The Rosetta mission has, through its contiguous in-situ and remote sensing coverage of comet 67P/Churyumov-Gerasimenko (hereafter ...

Lactylation of HSC70 Impairs Chaperone‐Mediated Autophagy to Promote Pyrin Inflammasome‐Dependent PANoptosis in Macrophages During Sepsis

Advanced Science, EarlyView.
In sepsis, lactate accumulation drives HSC70 K561 lactylation, which impairs chaperone‐mediated autophagy and blocks CUX1 degradation. Accumulated CUX1 transcriptionally upregulates Pyrin, triggering PANoptosis in macrophages and exacerbating inflammatory storm and organ injury.

Cometary Gas and Dust Delivered to Mars [PDF]

, 2018
This thesis investigates the interaction of cometary atmospheres (coma) and debris streams (meteor showers) on Mars' atmosphere. In this work, we use the close encounter of Comet Siding Spring (C/2013 A1) with Mars to investigate delivered cometary gas ...
