Neglect is at least as damaging as physical or sexual abuse in the long term but has received the least scientific and public attention. The high burden and serious and long-term consequences of child maltreatment warrant increased investment in preventive and therapeutic strategies from early childhood.”
“Spontaneous neural hyperactivity

in the central auditory pathway is MX69 mouse often associated with deafness, the most common form of which is partial hearing loss. We quantified both peripheral hearing loss and spontaneous activity in single neurons of the contralateral inferior colliculus in a guinea-pig model 1 week after a unilateral partial deafness induced by cochlear mechanical lesion. We also measured mRNA levels of candidate genes in the same animals using quantitative real-time PCR. Spontaneous hyperactivity was most marked in the frequency region of the peripheral hearing loss. Expression of glutamate decarboxylase 1 (GAD1), GABA-A receptor subunit alpha-1 (GABRA1), and potassium channel subfamily K member 15 (KCNK15) was decreased ipsilaterally in the cochlear nucleus and bilaterally in the inferior colliculus. A member

of RAB family of small GTPase (RAB3A) was decreased in both ipsilateral cochlear nucleus and contralateral inferior colliculus. RAB3 GTPase activating protein subunit 1 (RAB3GAP1) and glycine receptor subunit alpha-1 (GLRA1) were reduced ipsilaterally in the cochlear check nucleus only. These results suggest that a decrease CH5424802 mouse in inhibitory neurotransmission and an increase in membrane excitability may contribute to elevated neuronal spontaneous activity in the auditory brainstem following unilateral partial hearing loss.

“Obstructive sleep apnoea (OSA) is a common disorder in which repetitive apnoeas expose the cardiovascular system to cycles of hypoxia, exaggerated negative intrathoracic pressure, and arousals.

These noxious stimuli can, in turn, depress myocardial contractility activate the sympathetic nervous system, raise blood pressure, heart rate, and myocardial wall stress, depress parasympathetic activity, provoke oxidative stress and systemic inflammation, activate platelets, and impair vascular endothelial function. Epidemiological studies have shown significant independent associations between OSA and hypertension, coronary artery disease, arrhythmias, heart failure, and stroke. In randomised trials, treating OSA with continuous positive airway pressure lowered blood pressure, attenuated signs of early atherosclerosis, and, in patients with heart failure, improved cardiac function. Current data therefore suggest that OSA increases the risk of developing cardiovascular diseases, and that its treatment has the potential to diminish such risk.
