Predicting ALS informant distress from cognitive and behavioural change in people with ALS.
J Neurol
January 2025
Department of Psychology, Institute of Psychiatry, Psychology and Neuroscience, King's College London, London, UK.
Background: The cognitive and behavioural changes that occur in around 50% of people with amyotrophic lateral sclerosis (ALS) may significantly affect people around them, contributing to heightened burden, anxiety, and depression. Despite existing evidence linking behavioural impairment to caregiver distress, the role of cognitive impairment remains less clear, with mixed findings on its impact.
Methods: This study assessed the influence of cognitive and behavioural impairments in people with ALS on the distress of their nominated informants.
Melatonin induces drought stress tolerance by regulating the physiological mechanisms, antioxidant enzymes, and leaf structural modifications in L.

Melatonin is considered an effective bio-stimulant that is crucial in managing several abiotic stresses including drought. However, its potential mechanisms against drought stress in fragrant roses are not well understood. Here, we aim to investigate the role of melatonin on plants cultivated under drought stress (40 % field capacity) and normal irrigation (80 % field capacity).

For this reason, the CL must have robust quality systems in place in order to provide reliable results that help to ensure correct health care. Since the entry into force of the European regulation (IVDR) on in vitro diagnostic medical devices (EU) 2017/746 has generated the loss of CE marking in some laboratory determinations.

Department of Radiology, Weill Cornell Medicine, 413 E 69th Street, Room BB-1604, New York, NY, 10021, USA.
Purpose: Treatment of pediatric cancers with doxorubicin is a common and predictable cause of cardiomyopathy. Early diagnosis of treatment-induced cardiotoxicity and intervention are major determinants for the prevention of advanced disease. The onset of cardiomyopathies is often accompanied by profound changes in lipid metabolism, including an enhanced uptake of short-chain fatty acids (SCFA).

High-frequency stimulation (HFS)-induced long-term potentiation (LTP) is generally regarded as a homosynaptic Hebbian-type LTP, where synaptic changes are thought to occur at the synapses that project from the stimulation site and terminate onto the neurons at the recording site. In this study, we first investigated HFS-induced LTP on urethane-anesthetized rats and found that cortical HFS enhances neural responses at the recording site through the strengthening of local connectivity with nearby neurons at the stimulation site, rather than through synaptic strengthening at the recording site. This enhanced local connectivity at the stimulation site leads to increased output propagation, resulting in signal potentiation at the recording site.
