In a toy model we derive the gravitational equation on a self-gravitating curved D-brane. The effective theory on the brane is drastically changed from the ordinal Einstein equation. The net cosmological constant on the brane depends on a tuning between the brane tension and the brane charges. Moreover, non-zero matter stress tensor exists if the net cosmological constant is not zero. This fact...

Recently, we found that greater norepinephrine transporter (NET) availability in the locus coeruleus of trauma survivors with posttraumatic stress disorder (PTSD) was associated with increased severity of anxious arousal (i.e., hypervigilance and exaggerated startle) symptoms, but not any of the other empirically-derived symptom clusters that characterize this disorder.1 This finding suggests t...

The pathology between chronic stress, deregulation of serotonergic (5-HT) and noradrenergic (NE) neurotransmission and the onset of psychiatric disorders is poorly understood. Using in vivo chronoamperometry our previous findings showed 5-HT clearance is dramatically slower in chronically stressed wild-type mice, and that this reduction in clearance does not result from the loss of serotonin tr...

This article extends the debate initiated by Haslag, Nieswiadomy, and Slottje (1991, 1994) and Gamber and Sorensen (1994) in this journal about whether the net discount ratio can be described as a stationary process. Haslag, Nieswiadomy, and Slottje found discount ratios to be stationary. Gamber and Sorensen concluded that they are nonstationary; however, they identified the source of the nonst...

in this study gill-net selectivity for alburnus chalcoides inhabiting the almus dam lake was estimated. experimental gill-net fishing was conducted using gill-net with 15 mm and 20 mm mesh-size, during october 2002 and september 2003. a total of 254 and 198 specimens of a. chalcoides were caught by gill-net with 15 mm and 198 with the 20 mm mesh-size, respectively. the total length of the fish ...

results higher levels of stress were due to the fear of being infected by hiv and hepatitis patients with mean of 3.2 and 58%; and lack of weekends with mean of 3 and 44%. the lowest levels of stress were related to inadequate skills with mean of 2.18 and 32%, and environment light with mean of 2.14 and 34.7%. stress was significantly related to job status, conflict of doctors and nurses as wel...

BACKGROUND Norepinephrine (NE) is a primary neurotransmitter of central autonomic regulation and sympathetic nerve conduction, and the norepinephrine transporter (NET) is crucial in limiting catecholaminergic signaling. NET is sensitive to antidepressants, cocaine, and amphetamine. NET blockade often is associated with cardiovascular side effects, and NET deficiency is linked to tachycardia in ...

OBJECTIVES Noradrenergic dysfunction is implicated in obesity. The norepinephrine transporter (NET) regulates the synaptic availability of norepinephrine. However, NET availability has not been previously characterized in vivo in obese people using Positron Emission Tomography (PET) imaging. Here we report findings evaluating NET availability in individuals with obesity and matched lean (i.e., ...
