Radiographic Intraradicular Reduction of a Calcium Silicate–Based Sealer: Case Reports

International Endodontic Journal, EarlyView.
ABSTRACT Aim To document radiographically observable intraradicular reduction of AH Plus Bioceramic, a premixed calcium silicate–based sealer (CSBS), during clinical follow‐up after nonsurgical root canal retreatment. Summary Four cases of nonsurgical root canal retreatment performed with a premixed CSBS using a single‐cone obturation technique are ...

Outcome of Calcium Silicate Sealer‐Based Obturation in Root Canal Retreatment: A CBCT‐Based Prospective Cohort Study

International Endodontic Journal, EarlyView.
ABSTRACT Background Calcium silicate sealers (CSS) have become the dominant approach to root canal obturation in many specialist practices, yet evidence on their performance in nonsurgical retreatment is sparse and CBCT‐based assessment remains uncommon.

Study of the vibration frequency characteristics of tectonic coal containing assemblages at different loading rates

Scientific Reports
To reduce the vibration frequency superimposed on the original vibration frequency of a coal seam containing structural coal, damage to the coal structure should be reduced, and the occurrence of coal and natural gas outburst accidents should be ...

Guideline for Medication Management of Distressing Symptoms in Older Patients Receiving End‐of‐Life Palliative Care

Journal of Evidence-Based Medicine, EarlyView.
ABSTRACT Older patients receiving end‐of‐life palliative care often present with multiple geriatric syndromes, frailty, and comorbid symptom burden, resulting in a high risk of medication‐related harm. This guideline focuses on pharmacological management of distressing symptoms in older patients receiving end‐of‐life or hospice‐oriented palliative care,

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

Journal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.
