To explore the mechanism by which herpes simplex virus (HSV)-2 infection is related to HIV-1 acquisition, we conducted in situ analysis of the cellular infiltrate from sequential biopsies of HSV-2 lesions from patients on and off antiviral therapy. CD4(+) and CD8(+) T cells and a mixed population of plasmacytoid and myeloid dendritic cells (DCs), including(More)
Most herpes simplex virus 2 (HSV-2) reactivations in humans are subclinical and associated with rapid expansion and containment of virus. Previous studies have shown that CD8(+) T cells persist in genital skin and mucosa at the dermal-epidermal junction (DEJ)--the portal of neuronal release of reactivating virus--for prolonged time periods after herpes(More)
Sentiment classification aims at mining reviews of people for a certain event's topic or product by automatic classifying the reviews into positive or negative opinions. With the fast developing of World Wide Web applications, sentiment classification would have huge opportunity to help people automatic analysis of customers' opinions from the web(More)
Automatic text classification is one of the most important tools in Information Retrieval. As the traditional methods for text classification cannot find the best feature set, the GA is applied to the feature selection because it can get the global optimal solution. This paper presents a novel text classifier from positive and unlabeled documents based on(More)
Topical Web crawling is an established technique for domain-specific information retrieval. However, almost all the conventional topical Web crawlers focus on building crawlers using different classifiers, which needs a lot of labeled training data that is very difficult to labelmanually. This paper presents a novel approach called clustering-based topical(More)
KEY POINTS Using functional mapping assays, we conducted a quantitative assessment of both excitatory and inhibitory synaptic laminar connections to excitatory neurons in layers 2/3-6 of the mouse visual cortex (V1). Laminar-specific synaptic wiring diagrams of excitatory neurons were constructed on the basis of circuit mapping. The present study reveals(More)
