Testing the relationships of hope and negotiable fate with sleep quality among university students in Hong Kong.

For university students, who are often under significant stress to perform well, sleep is particularly important, playing roles in learning and academic performance. Research demonstrates a relationship between hope and sleep quality. However, most work concerns Western samples, and the hope construct has been criticized for a Western bias.

Rare but dangerous cause of non-purulent myopericarditis: a non-typhoidal infection.

We present a case of a young man in his early 20s who presented to the hospital with acute onset of central chest pain, preceded by epigastric fullness and diarrhoea 5 days after consuming a meal containing chicken products. Following an extensive evaluation, he was diagnosed with -associated myopericarditis. This case aims to raise awareness within the medical community about the cardiac effects of infection.

Physiological and molecular impairment of PV circuit homeostasis in mouse models of autism.

Circuit dysfunction in autism may involve a failure of homeostatic plasticity. To test this, we studied parvalbumin (PV) interneurons which exhibit rapid homeostatic plasticity of intrinsic excitability following whisker deprivation in mouse somatosensory cortex. Brief deprivation reduces PV excitability by increasing Kv1 current to increase PV spike threshold.
