Reactive stroma has been reported in many cancers, including breast, colon, and prostate. Although changes in stromal cell phenotype and extracellular matrix have been reported, specific mechanisms of how reactive stroma affects tumor progression are not understood. To address the role of stromal cells in differential regulation of tumor incidence, growth rate, and angiogenesis, LNCaP xenograft...

Unlike the important body of work on eyewitness memory, little research has been done on the accuracy and completeness of "earwitness" memory for conversations. The present research examined the effects of mode of presentation (audiovisual/ auditory-only) on witnesses' free recall for utterances in a criminal conversation at different retention intervals (immediate/delayed) within a single expe...

Sex cord-stromal tumors account for 5% of ovarian tumors and 2% of malignant ovarian tumors. Steroid cell tumors (SCT), not otherwise specified (NOS), are rare sex cord-stromal tumors of the ovary and account for less than 0.1% of all ovarian tumors. We report a rare case of a post-menopausal woman presented with hirsutism, virilism and with findings of hyperestrogenism.

Brain potentials associated with true and false recognition were recorded using a paradigm consisting of categorized color photographs. Two ERP components were identified. A parietal component was most positive for both true and false recognition, less positive for rejection of lures, and least positive for rejection of novel items. A later frontal component was more positive for false recognit...

In two experiments, predictions of the fuzzy-trace theory of memory were tested. Perceptual information may play a role in retrieval and recognition processes for verbatim, but not for gist, memory. Perceptual modality effects were assessed in the present study by presenting three-sentence stories (e.g., The bird is in the cage. The cage is over the table. The bird is yellow) and then testing r...

Humans can recognize the gist of a novel image in a single glance, independent of its complexity. How is this remarkable feat accomplished? On the basis of behavioral and computational evidence, this paper describes a formal approach to the representation and the mechanism of scene gist understanding, based on scene-centered, rather than object-centered primitives. We show that the structure of...

Existing literature suggests that feedback could effectively reduce false memories in younger adults. However, it is unclear whether memory performance in older adults also might be affected by feedback. The current study tested the hypothesis that older adults can use immediate feedback to adjust their memory strategy, similar to younger adults, but after feedback is removed, older adults may ...

as early as 1979, as part of the integrated drugs policy. (2) Flexible: Outreach measures were repeatedly modified, particularly in response to the HIV epidemic. (3) Effective: Both needle sharing behaviour and total consumption of "hard drugs" have declined in the city since introduction of outreach intervention. 60-80% of Amsterdam's hard drug using population is now in contact with treatment...
