Introduction: Root remediation when the initial treatment fails is the most basic treatment before any other surgical procedure. The aim of this study was to evaluate the factors affecting the success and failure of endodontic treatment in a period of 6-24 months.Materials and Methods:This cross-sectional analytical study was performed during 1996-94 with the participation of 76 patients, 19 (2...

Most compounds considered toxic to mammals should also be considered toxic to birds. Table 37.1 offers a guide for treatment of intoxication from some common household products. Based on their size and physiology, birds are more prone than mammals to intoxication by some compounds, such as volatile chemicals and fumes. Psittaciformes have a propensity to chew on almost anything. All avian clien...

Periodontitis, although not a cause of mortality, is also a major public health concern because of its high prevalence in the population and its negative impact on oral health, ability to chew, appearance, quality of life, dental care costs and tooth loss. In addition, as a progressive, chronic inflammatory disease, untreated periodontitis has the potential to undermine overall health and even ...

In 1949, Victor and Adams observed an alcoholic patient who developed quadriplegia and pseudobulbar palsy, and inability to chew, talk or swallow. A post-mortem confirmed their suspicion of 'a large, symmetrical, essentially demyelinative lesion occupying the greater part of the basis pontis.' This paper follows the historical evolution of central pontine myelinolysis and the changing concepts ...

The chemotactic response in E. coli is mediated through the receptor-regulated activity of the histidine protein kinase, cheA, which phosphorylates the response regulator, cheY (determining the direction of flagellar rotation) and the receptor modulator, cheB (providing receptor adaptation to prevailing conditions). Regulation of cheA by the receptor requires the coupling protein, cheW. CheA ph...

Coca-Erythroxylum coca Lamarck var. coca-remains one of the most common plants of the folk medicine of Bolivia used as a general stimulant. Aymara and Quechua natives prefer to chew the sweeter coca leaves from the Yungas (tropical mountain forests of the eastern slopes of the Andes) rather than those from the Chapare lowlands. The contents in cocaine and minor constituents of leaf samples cult...

An intuitively natural consistency condition for contingent plans is necessary and suucient for a contingent plan to be rationalized by maxi-mization of conditional expected utility. One alternative theory of choice under uncertainty, the weighted-utility theory developed by Chew Soo Hong (1983) does not entail that contingent plans will generally satisfy this condition. Another alternative the...

Bacterial chemotaxis is mediated by signaling complexes that sense chemical gradients and direct bacteria to favorable environments by controlling a histidine kinase as a function of chemoreceptor ligand occupancy. Core signaling complexes contain two trimers of transmembrane chemoreceptor dimers, each trimer binding a coupling protein CheW and a protomer of the kinase dimer. Core complexes ass...
