BACKGROUND The human intestine is host to an enormously complex, diverse, and vast microbial community-the gut microbiota. The gut microbiome plays a profound role in metabolic processing, energy production, immune and cognitive development, epithelial homeostasis, and so forth. However, the composition and diversity of the gut microbiome can be readily affected by external factors, which raise...

A case of bilateral fusion is presented, the definitions of fusion and gemination are reviewed, as well as the diagnostic criteria. The clinical implications of fused teeth include the probability of loss of arch length, caries susceptibility of the fissure, and missing corresponding permanent incisors. Introduction In 1963 Tannenbaum and Ailing, defined gemination as the formation of the equiv...

Neurological rehabilitation involving motor training has resulted in clinically meaningful improvements in function but is unable to eliminate many of the impairments associated with neurological injury. Thus there is a growing need for interventions that facilitate motor learning during rehabilitation therapy, to optimize recovery. d-Cycloserine (DCS), a partial N-methyl-d-aspartate (NMDA) rec...

Inflammatory bowel disease (IBD) is a chronic relapsing inflammatory disorder of the bowel. The etiology remains unknown, but IBD is immune-driven and multiple factors including genetic, environmental, and microbiological components play a role. Recombinase-activating gene-2deficient (Rag2−/−) mice infected with Helicobacter hepaticus (H. hepaticus) have been developed as an animal model to imi...

A state space version of the skew Toeplitz theory for (distributed) H" optimization theory is presented. The approach combines this theory with the realization theory for pseudorational transfer functions. 1 Time-Domain Interpretation of Sarason Space In [15], we established a strong link between the skew Toeplitz H" theory of 12, 4, 5, 6, 9, 121 and its realization in the time domain. The fund...

An unusual case of fusion combined with concrescence of a supernumerary tooth and a central incisor is presented. In order to prevent a deep periodontal pocket following the separation, a twostep technique was attempted. The first stage consisted of surgical exposure of the roots and separation with closure to allow in-growth of connective tissue. Four weeks later, the fused crowns were separat...

The concentration of 7,12-dimethylbenz(a)anthracene ( D M B A ) i n mamm-Lry tissue was determined at different time intervals following its administration, in a single dose, to female Sprague-Dawley rats maintained on 3 different semisynthetic diets: low fat, high coconut oil, and high corn oil. In general, the rate of uptake and clearance of the carcinogen was similar in the 3 groups, with a ...
