Intervention outcomes of children with non‐degenerative dystonia and associated hyperkinetic movement disorders: A scoping review

Developmental Medicine &Child Neurology, EarlyView.
Abstract Aim To identify the outcomes reported in published studies of intervention approaches used with non‐degenerative childhood hyperkinetic movement disorders, including dystonia, dyskinesia, hypertonia, athetosis, chorea, cerebral palsy, involuntary movement, and kernicterus, and map them to the International Classification of Functioning ...

Dust Production Rates in Jupiter-family Comets: A Two Year Study with ATLAS Photometry

The Planetary Science Journal
Jupiter-family comets (JFCs) exhibit a wide range of activity levels and mass loss over their orbits. We analyzed high-cadence observations of 42 active JFCs with the wide-field Asteroid Terrestrial-impact Last Alert System (ATLAS) in 2020–

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

The FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

Analysing Resilience Indicator Traits in Austrian Fleckvieh, Brown Swiss and Holstein‐Friesian Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Recent studies suggest that variations in milk yield during lactation can serve as a metric for assessing individual resilience, with minimum fluctuations reflecting greater resilience in cows. With automatic milking systems, multiple records can be obtained from many cows on a daily basis. Given that animals are continually exposed to a range

Comet 289P/Blanpain: Near-perihelion Activity and the Phoenicids

The Astronomical Journal
We present NEOWISE observations of Jupiter family comet 289P/Blanpain, the parent body of the Phoenicid meteoroid stream. Near-infrared images at 3.4 μ m (W1) and 4.6 μ m (W2) were obtained near perihelion on two occasions: UT 2019 October 30 (inbound ...

The immobilization of GOX in slides for comet sssay provides a useful tool for investigation of the efficiency of the cellular DNA-integrity protecting system of the target cells.

Frontiers in Genetics, 2015
Various modifications of Comet Assay are widely used for efficiency analysis of the cellular DNA-integrity protecting system (Azqueta et al., 2014). The nucleoids of eukaryotic cells immobilized in agarose gel and lyzed were used as a substrate for DNA ...

The Origins of Ploem's Filter Cube: A Pandora's Box

Journal of Microscopy, EarlyView.
Abstract Ploem's filter cube, central to modern epifluorescence microscopy, integrates three matched optical components: an excitation filter, an emission filter, and a dichroic mirror. Together, these elements enable the separation of excitation and emission light paths, producing high‐contrast fluorescence images.

Nucleus Ice Associations in Comets Derived from Spatially Resolved Properties of Volatile Gases in the Coma

The Planetary Science Journal
Under favorable conditions, high-resolution long-slit infrared spectroscopic observations of comets can provide information on how ices are associated within the nucleus from spatially resolved properties of volatiles in the coma.

A description of dental microanatomy and implantation geometry in Chamaeleonidae

Journal of Anatomy, EarlyView.
A reassessment of the dental histology in adult chamaeleons reveals the presence of periodontal ligament. Alongside alveolar bone and cementum, these tissues together constitute a compacted and remodelled tripartite periodontium. Our findings include the novel observation of plicidentine‐like protuberances of dentine within underlying bone.
