on cotton in strains of T. virens containing two ech42 copies and a disrupted ech42 gene …

The filamentous fungi Aspergillus niger and Hypocrea jecorina (Trichoderma reesei) have
been the subject of many studies investigating the mechanism of transcriptional regulation of …

… Both motifs are strictly necessary for transcription of xylanase I (R. Rauscher and RL Mach,

Objectives Amyloid‐β 42 (Aβ 42 ) appears central to Alzheimer's disease (AD) pathogenesis
and is a major component of amyloid plaques. Mean cerebrospinal fluid (CSF) Aβ 42 is …

Background: Beta-amyloid (Aβ) plaques are the hallmark of Alzheimer disease (AD). A PET
imaging tracer that binds to Aβ plaques in vivo, N-methyl-[ 11 C]2-(4′-methylaminophenyl)-6…

Disruption of the dopaminergic system has been implicated in the etiology of many pathological
conditions, including drug addiction. Here we used positron emission tomography (PET) …

… Mean rates of cocaine self-administration were inversely related to baseline D2 receptor
availability from weeks 4 through 10 (r = −0.66 to −0.80, P < 0.05; Table 2). This correlation was …

Xyr1 (xylanase regulator 1) of the ascomycete Hypocrea jecorina (anamorph Trichoderma
reesei) was recently demonstrated to play an essential role in the transcriptional regulation of …

Alzheimer's disease (AD) pathology is estimated to develop many years before detectable
cognitive decline. Fluid and imaging biomarkers may identify people in early symptomatic and …

Amyloid-β (Aβ) plaque deposition can precede the clinical manifestations of dementia of the
Alzheimer type (DAT) by many years and can be associated with changes in brain …
