Molecular chaperones such as Hsp70 use ATP binding and hydrolysis to prevent aggregation and ensure the efficient folding of newly translated and stress-denatured polypeptides. Eukaryotic cells contain several cytosolic Hsp70 subfamilies. In yeast, these include the Hsp70s SSB and SSA as well as the Hsp110-like Sse1/2p. The cellular functions and interplay(More)
OBJECTIVE To describe a novel set of scaphocephaly severity indices (SSIs) for predicting and quantifying head- and skull-shape deformity in children diagnosed with isolated sagittal synostosis (ISS) and compare their sensitivity and specificity with those of the traditional cranial index (CI). METHODS Computed tomography head scans were obtained from 60(More)
Craniosynostosis is a serious condition of childhood, caused by the early fusion of the sutures of the skull. The resulting abnormal skull development can lead to severe deformities, increased intra-cranial pressure, as well as vision, hearing and breathing problems. In this work we develop a novel approach to accurately classify deformations caused by(More)
Craniosynostosis is a serious and common pediatric disease caused by the premature fusion of the sutures of the skull. Early fusion results in severe deformities in skull shape due to the restriction of bone growth perpendicular to the fused suture and compensatory growth in unfused skull plates. Calvarial (skull) abnormalities are frequently associated(More)
OBJECTIVE To describe novel severity indices with which to quantify severity of trigonocephaly malformation in children diagnosed with isolated metopic synostosis. METHODS Computed tomographic scans of the cranium were obtained from 38 infants diagnosed with isolated metopic synostosis and 53 age-matched control patients. Volumetric reformations of the(More)
Similarity-based image retrieval is part of the case-based reasoning scenario. It allows for the retrieval of images from a database that are similar in some way to a given query image. It has been used in case-based reasoning systems for both image segmentation and image interpretation. Whereas case-based reasoning focuses on incremental learning of(More)
OBJECTIVES To measure severity of trigonocephaly among infants with single-suture metopic craniosynostosis by using a novel shape descriptor, the trigonocephaly severity index (TSI), and to evaluate whether degree of trigonocephaly correlates with their neurodevelopmental test scores. METHODS We conducted a multicenter cross-sectional and longitudinal(More)
OBJECTIVE To examine the association between severity of scaphocephalic skull malformation and neurodevelopmental status prior to cranioplasty. DESIGN AND PARTICIPANTS Seventy-five infants with single-suture sagittal craniosynostosis (median age, 4.5 months) referred to the Infant Learning Project, a prospective, multisite, longitudinal study to evaluate(More)
