Inflammatory bowel disease (IBD) has been attributed to overexuberant host immunity or the emergence of harmful intestinal flora. The transcription factor T-bet orchestrates inflammatory genetic programs in both adaptive and innate immunity. We describe a profound and unexpected function for T-bet in influencing the behavior of host inflammatory activity(More)
BACKGROUND Secondary-ion mass spectrometry (SIMS) is an important tool for investigating isotopic composition in the chemical and materials sciences, but its use in biology has been limited by technical considerations. Multi-isotope imaging mass spectrometry (MIMS), which combines a new generation of SIMS instrument with sophisticated ion optics, labeling(More)
Dravet syndrome is an intractable epileptic encephalopathy characterized by early onset epileptic seizures followed by cognitive decline, hyperactivity, autistic behaviors and ataxia. Most Dravet syndrome patients possess heterozygous mutations of SCN1A gene encoding voltage-gated sodium channel αI subunit (Nav1.1). We have previously reported that mice(More)
Aromatic L-amino acid decarboxylase (AADC) deficiency is a rare inborn error of neurotransmitter biosynthesis that leads to a combined deficiency of catecholamines and serotonin and is characterized by global developmental delay, involuntary movements, and autonomic dysfunction. We report the case of an 11-year-old male patient with AADC deficiency who also(More)
The cells of the subodontoblastic cell-rich layer in dental pulp are speculated to contain odontoblast progenitor cells because of their positional relationship with odontoblasts as well as their high alkaline phosphatase (ALP) activity. However, it has yet to be determined whether these cells have the ability to differentiate into odontoblastic cells. In(More)
The effects of isometric antagonist conditioning contraction (ACC) at various durations and intensities on the contractile force, electromyographic (EMG) amplitude, and their rates of rise of elbow flexor muscles were examined in healthy participants. In particular, we focused on the change in the maximum rate of initial force development of agonists(More)
An alkaline mannanase (EC from the alkaliphilic Bacillus sp. strain JAMB-602 was cloned and sequenced. The deduced amino-acid sequence of the enzyme suggested that the enzyme consists of a catalytic and unknown additional domains. The recombinant enzyme expressed by B. subtilis was crystallized using the hanging-drop vapour-diffusion method at 277(More)
Many homeodomain transcription factors function in organogenesis and cell differentiation. The Nkx family illustrates these functions especially well, and the Nkx6 subfamily controls differentiation in the central nervous system and pancreas. Nkx6.3, a recent addition to this subfamily, overlaps Nkx6.1 and Nkx6.2 in expression in the hindbrain and stomach.(More)
BACKGROUND & AIMS The gastric mucosa provides a stringent epithelial barrier and produces acid and enzymes that initiate digestion. In this regenerating tissue, progenitors differentiate continually into 4 principal specialized cell types, yet underlying mechanisms of differentiation are poorly understood. We identified stomach-restricted expression of the(More)
