Arabidopsis type I metacaspases control cell death.

Metacaspases are distant relatives of animal caspases found in protozoa, fungi, and plants. Limited experimental data exist defining their function(s), despite their discovery by homology modeling a decade ago. We demonstrated that two type I metacaspases, AtMC1 and AtMC2, antagonistically control programmed cell death in Arabidopsis.

Effects of non-REM sleep on ventilation and respiratory mechanics in adults with cystic fibrosis.

To determine the effects of sleep upon respiratory function, five adult patients with cystic fibrosis (CF) were monitored during sleep in a horizontal body plethysmograph. Tidal volume (VT) decreased during non-rapid-eye-movement (NREM) sleep, resulting in a NREM sleep-associated decrement in minute ventilation (VI = 11.10 +/- 0.

Influence of sleep on respiratory function in emphysema.

To assess the influence of sleep on respiratory function, five patients with chronic obstructive pulmonary disease (COPD) with laboratory evidence of emphysema were monitored during sleep in a horizontal body plethysmograph. Neither lung volume nor lower airway resistance (Rla) changed in association with sleep. Upper airway resistance (Rua) increased during sleep and was highest during rapid eye movement (REM) sleep (Rua = 5.

Influence of non-REM sleep on inspiratory muscle activity and lung volume in asthmatic patients.

To determine the effect of non-REM (NREM) sleep on inspiratory muscle electromyographic (EMG) activity in asthmatic patients and the subsequent effect of such changes on FRC, 12 asthmatic patients with nocturnal worsening were monitored overnight in a horizontal volume-displacement body plethysmograph. During studies FRC was monitored using the single inspiratory occlusion technique, whereas EMG activities of the diaphragm (DI), intercostal (IC), and sternocleidomastoid (SCM) muscles were monitored using surface electrodes. FRC decreased progressively, from 3.

Drawing a connection from victim to victimizer.

1. The biological basis of the altered alarm/dissociative process during and after sexual trauma impedes the development of information processing essential for discerning intention, personal responsibility, sense of control over events, and trust in others. 2.
