avulsion is one of the most serious emergencies in dental office. in the event of any problem, the tooth should be stored in a medium that supports the periodontal ligament cell viability. in other clinical situations, preserving media, growth factors and mitogenic products may be useful in repairing the traumatized tissues. it has been previously reported that levodopa (l-dopa) accelerates hea...

Specific environmental stresses may lead to induced genomic instability in bacteria, generating beneficial mutants and potentially accelerating the breeding of industrial microorganisms. The environmental stresses inside the aqueous battery may be derived from such conditions as ion shuttle, pH gradient, free radical reaction and electric field. In most industrial and medical applications, elec...

AIMS To establish a simple method of quantitative culture for determining the viable bacterial numbers present in expectorated sputum samples. METHODS Sputum samples were homogenised with dithiothreitol, sterile saline or glass beads to determine which method recovered the greatest number of viable bacteria. Culture broths were also incubated with dithiothreitol and sampled over time to deter...

Environmental stresses induce several plant pathogenic bacteria into a viable but nonculturable (VBNC) state, but the basis for VBNC is largely uncharacterized. We investigated the physiology and morphology ofthe copper-induced VBNC state in the plant pathogen Ralstonia solanacearum in liquid microcosm. Supplementation of 200 μM copper sulfate to the liquid microcosm completely suppressed bacte...

Estriol accounts for an average of 74% of the principal Kober-positive steroids in the urine of 13 women during uncomplicated pregnancies. This proportion is independent of the stage of pregnancy, from 20 weeks until term. The average ratio of estriol to ring-D a#{149}ketols (mainly 16ahydroxyestrone and 16-ketoestradiol-17) is about 5:1 over the same period. In 17 pregnant women with diabetes,...

In the past fifteen years, the United States Supreme Court has decided three cases in which it tentatively began to explore what the United States Constitution has to say about issues that are popularly described as the "right to die." In this article, I suggest that the current state of constitutional analysis does not provide for an effective mechanism for securing an individual's "right to d...

conclusions the bacterial isolates exhibited strong biofilm formation potential, while the extracts of acacia arabica significantly inhibited biofilm formation among the isolates and, therefore, could be executed in the development of cost-effective biofilm inhibitor medicines. results pseudomonas aeruginosa (kc417303-05), staphylococcus hemolyticus (kc417306), and staphylococcus hominis (kc417...

The seemingly inexorable spread of antibiotic resistance genes among microbial pathogens now threatens the long-term viability of our current antimicrobial therapy to treat severe bacterial infections such as sepsis. Antibiotic resistance is reaching a crisis situation in some bacterial pathogens where few therapeutic alternatives remain and pan-resistant strains are becoming more prevalent. No...

conclusions p. gingivalis and p. intermedia could play a role in implant failure by changing the expression profiles of genes related to bone formation and resorption. results viability was reduced to 56.8% (p. gingivalis) and 52.75% (p. intermedia) at 1000 multiplicity. amongst 48 genes examined, expressions of bmper, smad1, il8 and nfrkb were found to be highly upregulated by both bacterial c...
