We retrospectively studied the expression of Yes-associated protein (YAP) using immunohistochemical staining in 10 cases of head and neck squamous cell carcinoma with associated perineural invasion. We find that fibroblasts in areas associated with perineural invasion show higher levels of nuclear YAP compared to fibroblasts in the stroma of normal mucosa, with a median cell count of 35.4 per h...

The lower parallactic depth threshold is determined by (a) the ratio of relative image velocity to head velocity when the head moves fast (>13 cm/s) and (b) the motion threshold when the head moves slow (<13 cm/s). These two results are explained by a single system that codes the ratio of relative image velocity to head velocity, using the same image velocity signal as that used for motion perc...

Kikuchi–Fujimoto disease (KFD) is a rare benign lymphadenopathy, also known as histiocytic necrotizing lymphadenitis [1]. KFD is a self-limited disease that predominantly affects young women and is generally associated with autoimmune pathologies [1]. In October 2013, a 22-year-old North-African female with sickle cell disease (SCD) under hydroxyurea treatment (HU; 20 mg/kg/d) presented with ac...

CONTEXT Mid-arm circumference of the newborn is strongly associated with birth weight and is a very good indicator of low and insufficient birth weight. However, there are few Brazilian studies on the relationship between mid-arm and head circumferences and, thus, this does not form part of the routine evaluation for newborns. OBJECTIVES To establish the mid-arm circumference and mid-arm/head...

Hudson (1990) proposes that each conjunct in a coordinate phrase forms dependency relations with heads or dependents outside the coordinate phrase (the "multi-head" view). This proposal is tested through corpus analysis of Wall Street Journal text. For right-branching constituents (such as direct-object NPs), a short-long preference for conjunct ordering is observed; this is predicted by the mu...
