Predicting Dental Caries Outcomes in Children: A "Risky" Concept
In recent years, unprecedented gains in the understanding of the biology and mechanisms underlying human health and disease have been made. In the domain of oral health, although much remains to be learned, the complex interactions between different systems in play have begun to unravel: host genome, oral microbiome with its transcriptome, proteome and metabolome, and more distal influences, including relevant behaviors and environmental exposures. A reasonable expectation is that this emerging body of knowledge can help improve the oral health and optimize care for individuals and...περισσότερα »
FT-Raman Spectroscopy Study of the Remineralization of Microwave-Exposed Artificial Caries
Dental caries is a microbially mediated disease that can result in significant tooth structure degradation. Although the preponderance of lesions is treated by surgical intervention, various strategies have been developed for its noninvasive management. Here, we use a novel approach for noninvasive treatment based on killing *Streptococcus mutans* with high-frequency microwave energy (ME). The rationale for this approach is based on modulating the pH of caries to a physiological state to enable spontaneous tooth remineralization from exogenous sources. In the present study, after ... περισσότερα »
MRI/MRS as a surrogate marker for clinical progression in GM1 Gangliosidosis
Background GM1 gangliosidosis is a lysosomal storage disorder caused by mutations in GLB1, encoding β-galactosidase. The range of severity is from type I infantile disease, lethal in early childhood, to type III adult onset, resulting in gradually progressive neurological symtpoms in adulthood. The intermediate group of patients has been recently classified as having type II late infantile subtype with onset of symptoms at one to three years of age or type II juvenile subtype with symptom onset at 2–10 years. To characterize disease severity and progression, six Late infantile an... περισσότερα »
Triplication of 16p12.1p12.3 associated with developmental and growth delay and distinctive facial features
The 16p12 region is particularly prone to genomic disorders due to the large number of low copy repeats [Martin et al., 2004; Nature 432:988–994]. We report two unrelated patients with de novo triplication of 16p12.1p12.3 who had developmental delay and similar facial features. Patient 1 is a 4-year-old male with a congenital heart anomaly, bilateral cryptorchidism, chronic constipation, and developmental delay. Patient 2 is a 12-year-old female with prenatally diagnosed hydronephrosis, hepatobiliary disease, failure to thrive, and developmental delay. Distinctive facial features ... περισσότερα »
Diversity and Divergence of Dinofagellate Histone Proteins
Histone proteins and the nucleosomal organization of chromatin are near-universal eukaroytic features, with the exception of dinoflagellates. Previous studies have suggested that histones do not play a major role in the packaging of dinoflagellate genomes, although several genomic and transcriptomic surveys have detected a full set of core histone genes. Here, transcriptomic and genomic sequence data from multiple dinoflagellate lineages are analyzed, and the diversity of histone proteins and their variants characterized, with particular focus on their potential posttranslational ... περισσότερα »
A Genome-Wide Screen with Nicotinamide to Identify Sirtuin-Dependent Pathways in Saccharomyces cerevisiae
Sirtuins are evolutionarily conserved NAD-dependent deacetylases that catalyze the cleavage of NAD+ into nicotinamide (NAM), which can act as a pan-sirtuin inhibitor in unicellular and multicellular organisms. Sirtuins regulate processes such as transcription, DNA damage repair, chromosome segregation and longevity extension in yeast and metazoans. The founding member of the evolutionarily conserved sirtuin family, *SIR2*, was first identified in budding yeast. Subsequent studies led to the identification of four yeast *SIR2* homologs *HST1*, *HST2*, *HST3*, and *HST4*. Understand...περισσότερα »

Level dependence of the nonlinear-distortion component of distortion-product otoacoustic emissions in humansa)
Level dependence of the nonlinear-distortion component of distortion-product otoacoustic emissions in humansa): Distortion-product otoacoustic emissions (DPOAEs) emerge when presenting two primary tones with different frequencies f1 and f2 to the cochlea and are commonly used in diagnosis and research to evaluate the functional state of the cochlea. Optimal primary-tone stimulus levels accounting for the different level dependencies of the traveling-wave amplitudes of the two primary tones near the f2-tonotopic place on the basilar membrane are often used to maximize DPOAE amplitud...περισσότερα »

Rates and Predictors of Seizure Freedom With Vagus Nerve Stimulation for Intractable Epilepsy.
BACKGROUND: Neuromodulation-based treatments have become increasingly important in epilepsy treatment. Most patients with epilepsy treated with neuromodulation do not achieve complete seizure freedom, and, therefore, previous studies of vagus nerve stimulation (VNS) therapy have focused instead on reduction of seizure frequency as a measure of treatment response. OBJECTIVE: To elucidate rates and predictors of seizure freedom with VNS. METHODS: We examined 5554 patients from the VNS therapy Patient Outcome Registry, and also performed a systematic review of the literature including ... περισσότερα »

Thoracic Myoepithelial Tumors: A Pathologic and Molecular Study of 8 Cases With Review of the Literature.
Thoracic myoepithelial tumors (MTs) are a rare group of tumors showing predominant or exclusive myoepithelial differentiation. They are poorly characterized from both a morphologic and genetic standpoint, in particular features that separate benign from malignant behavior. We examined the histologic and immunohistochemical features of 8 primary thoracic MTs and performed fluorescence in situ hybridization for EWSR1, FUS, PLAG1, and HMGA2, as well as several partner genes. Half (4/8) of the MTs occurred in large airways, and 3 had infiltrative borders. All cases showed immunoreactivi... περισσότερα »
Loss of H3K27me3 Expression Is a Highly Sensitive Marker for Sporadic and Radiation-induced MPNST.
Most malignant peripheral nerve sheath tumors (MPNSTs) exhibit combined inactivation of NF1, CDKN2A, and polycomb repressive complex 2 component genes (Embryonic Ectoderm Development [EED] and Suppressor of Zeste 12 [SUZ12]). Mutations in EED and SUZ12 induce loss of trimethylation at lysine 27 of histone 3 (H3K27me3), with subsequent aberrant transcriptional activation of polycomb repressive complex 2-repressed homeobox master regulators. These findings prompted us to investigate the performance of an anti-H3K27me3 monoclonal antibody clone C36B11 as an immunohistochemical marker f... περισσότερα »
