During mammalian cerebral corticogenesis, progenitor cells become progressively restricted in the types of neurons they can produce. The molecular mechanism that determines earlier versus later born neuron fate is unknown. We demonstrate here that the generation of the earliest born neurons, the Cajal-Retzius cells, is suppressed by the telencephalic(More)
The winged helix gene Brain factor-1 (BF1) has a pleiotropic role in the development of the cerebral hemispheres of the brain. Mice lacking BF1 have defects in the morphogenesis of the structures of the dorsal telencephalon (e.g., neocortex) and the ventral telencephalon (e.g., the basal ganglia). This study focuses on the functions of BF1 in the dorsal(More)
In animals with binocular vision, retinal ganglion cell (RGC) axons from each eye sort in the developing ventral diencephalon to project to ipsi- or contralateral targets, thereby forming the optic chiasm. Ipsilaterally projecting axons arise from the ventrotemporal (VT) retina and contralaterally projecting axons primarily from the other retinal quadrants.(More)
OBJECTIVE To compare the criteria for Wegener's granulomatosis (WG) of the American College of Rheumatology (ACR) with those of the European League Against Rheumatism/Pediatric Rheumatology European Society (EULAR/PRES) in a cohort of children with WG and other antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs), and to describe the(More)
ObjectivesTo evaluate the psychometric properties of the KINDL questionnaire in an Asian population. Methods: Consecutive patients with diabetes mellitus (DM) and healthy subjects were recruited to complete the English KINDL questionnaire. The inclusion criteria for patients were age 8–16 years, English-speaking, diagnosed with DM and absence of co-morbid(More)
Thymocyte winged helix (TWH) is a putative transcription factor expressed in the developing neural tube. At midgestation, TWH expression identifies subsets of spinal cord motor neurons and interneurons. TWH-expressing motor neurons were restricted to specific spinal cord levels, distinguishing motor neurons at lumbar from those at cervical levels. To(More)
OBJECTIVE Juvenile localized scleroderma (LS) is a chronic inflammatory skin disorder associated with substantial morbidity and disability. Although a wide range of therapeutic strategies has been reported in the literature, a lack of agreement on treatment specifics and accepted methods for clinical assessment has made it difficult to compare approaches(More)
OBJECTIVE To evaluate the construct validity of 2 proposed measures (the Ultrasound Disease Activity [U-DA] and the Tissue Thickness Score [TTS]) for evaluating sonographic differences in juvenile localized scleroderma skin lesions. METHODS We conducted a retrospective review of juvenile localized scleroderma patients who had ultrasound scans of their(More)
Validity and reliability of a Singaporean English EQ-5D self-report questionnaire (EQ-5D) were evaluated among consecutive outpatients with rheumatic diseases attending a tertiary referral hospital in Singapore (a multi-ethnic, urban Asian country). Subjects were interviewed twice within a 2-week period using a standardized questionnaire containing the(More)
Objective: This study aimed to validate the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30, English version 3.0) in Singaporean cancer patients. Methods: In a cross-sectional study, a heterogeneous sample of cancer patients (n = 57) self-administered a questionnaire containing the QLQ-C30, the Short(More)
