Experiments and simulations demonstrating the rapid ultrasonic rewarming of frozen tissue cryovials [PDF]

, 2023
The development of methods to safely rewarm large cryopreserved biological samples remains a barrier to the widespread adoption of cryopreservation. Here, experiments and simulations were performed to demonstrate that ultrasound can increase rewarming ...

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Pharmacological vasodilatation improves efficiency of rewarming from hypothermic cardiopulmonary bypass

, 1998
An afterdrop in core temperature after hypothermic cardiopulmonary bypass (CPB) is related to inadequate peripheral rewarming. We proposed that pharmacological vasodilatation during rewarming on bypass would improve peripheral rewarming and reduce the ...

CoolCuddle and Autonomic Regulation in Infants With Hypoxic‐Ischaemic Encephalopathy: An Intervention Study

Acta Paediatrica, EarlyView.
ABSTRACT Aim We evaluated the impact of ‘CoolCuddle’, parental cuddling during therapeutic hypothermia intervention for hypoxic‐ischaemic encephalopathy, on heart rate variability (HRV). Methods In this prospective, single‐group, interventional study with repeated measures, we included infants ≥ 36 weeks' gestation undergoing hypothermia and CoolCuddle

Is prehospital use of active external warming dangerous for patients with accidental hypothermia: a systematic review

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, 2020
Background Optimal prehospital management and treatment of patients with accidental hypothermia is a matter of frequent debate, with controversies usually revolving around the subject of rewarming.

Early Prediction of Outcome Using Lactate Dehydrogenase and Amplitude‐Integrated EEG in Transported Newborn Infants with Hypoxic–Ischaemic Encephalopathy

Acta Paediatrica, EarlyView.
ABSTRACT Aim To investigate whether early lactate dehydrogenase (LDH) and amplitude‐integrated electroencephalography (aEEG) improve the prediction of outcome in outborn infants transported for therapeutic hypothermia. Method Secondary analysis of a randomised controlled trial (2016–2019) including 113 asphyxiated newborn infants randomised to ...

Pathophysiology and emerging treatments for dermographic, cholinergic and cold urticaria

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This review illustrates key proposed mast cell‐mediated activation pathways in dermographic, cholinergic and cold urticaria, highlighting IgE‐dependent and ‐independent mechanisms. These pathways are increasingly targeted by emerging drugs, aiming to interrupt mast cell activation and mediator release, offering more precise, mechanism‐based treatment ...

Melatonin seed priming: A climate‐smart, green strategy to enhance abiotic stress tolerance in plants

Journal of Integrative Plant Biology, EarlyView.
This review synthesizes how melatonin seed priming preconditions seeds to enhance tolerance against diverse abiotic stresses. It highlights the underlying mechanisms and proposes an integrative roadmap of advanced molecular and breeding tools to design next‐generation, stress‐smart plants.

Nanowarming of vitrified pancreatic islets as a cryopreservation technology for transplantation

Bioengineering & Translational Medicine, 2023
Biobanking of pancreatic islets for transplantation could solve the shortage of donors, and cryopreservation of vitrified islets is a possible approach. However, a technological barrier is rewarming of large volumes both uniformly and rapidly to prevent ...

Preclinical 1H MRS Study of a Porcine Model Shows Evidence and Mechanisms for Acute Neuronal Injury in Neonatal Cardiopulmonary Bypass (CPB) Surgery

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 557-567, August 2026.
ABSTRACT Purpose Congenital heart disease affects 1% of US births, with some infants requiring cardiothoracic surgery under cardiopulmonary bypass (CPB). Optimal surgical parameters to minimize neuronal injury are unknown. We used serial 1H MRS in a neonatal CPB porcine model to assess acute neuronal damage and associated injury mechanisms.
