Since the introduction of Linehan's treatment manuals in 1993, dialectical behavior therapy (DBT) has been widely disseminated throughout multiple therapeutic settings and applied to a variety of diagnoses. The enthusiasm with which it was embraced by clinicians early on led some to question whether DBT's popularity was outstripping its empirical(More)
BACKGROUND Few data are currently available investigating neurosteroids (NS) in Alzheimer's disease (AD). The NS allopregnanolone may be decreased in serum and plasma in patients with AD, but it is unclear if allopregnanolone is also reduced in brain. Because a number of NS exhibit neuroprotective effects and impact cognitive performance in rodent models,(More)
Evidence suggests that neuroactive steroids may be candidate modulators of schizophrenia pathophysiology and therapeutics. We therefore investigated neuroactive steroid levels in post-mortem brain tissue from subjects with schizophrenia, bipolar disorder, nonpsychotic depression, and control subjects to determine if neuroactive steroids are altered in these(More)
Olanzapine and fluoxetine elevate the GABAergic neuroactive steroid allopregnanolone to physiologically relevant concentrations in rodent cerebral cortex. It is unknown if these agents also alter pregnenolone or deoxycorticosterone. Since olanzapine and fluoxetine in combination have clinical utility and may demonstrate synergistic effects, we investigated(More)
We have built an experimental link-level authenticated ad hoc routing protocol and integrated it with the PSU version of Mobile-IP. The routing protocol is intended to address survivability and link security issues. In our modiied version of Mobile-IP, we authenticate ICMP router discovery packets, which are sent by both Mobile-IP agents and mobile nodes.(More)
Nicotine administration alters neuroactive steroids in rodent models, and serum levels of the neuroactive steroid DHEAS (dehydroepiandrosterone sulfate) appear to be higher in smokers. These molecules may be relevant to tobacco addiction and affective symptoms. This study aims to investigate DHEAS, allopregnanolone, pregnenolone, and other steroids in male(More)
BACKGROUND Several studies have linked geriatric depression with cerebrovascular disease. The apolipoprotein E gene (APOE) epsilon 4 allele has been associated with a variety of late-life neuropsychiatric disorders, including Alzheimer's disease, vascular dementia, and depression. METHODS The sample consisted of 145 elderly depressive individuals and 100(More)
OBJECTIVE To standardize and objectivize treatment response assessment in oncology, guidelines have been proposed that are driven by radiological measurements, which are typically communicated in free-text reports defying automated processing. We study through inter-annotator agreement and natural language processing (NLP) algorithm development the task of(More)
Radiological measurements are one of the key variables in widely adopted guidelines (WHO, RECIST) that standardize and objectivize response assessment in oncology care. Measurements are typically described in free-text, narrative radiology reports. We present a natural language processing pipeline that extracts measurements from radiology reports and pairs(More)
