Sealing Ability of Obturation with Different Sealers Applied Over Apically Separated Rotary File - Retrograde Bacterial Leakage Study.

Background And Aims: . Retrieval of separated rotary file may not be possible many times. Then sealing of coronal root canal system depends on sealing ability of root canal sealers.

"Sporotan" a new fluorescent stain for identifying cryptic spores of Rhodobacter johrii.

We propose a new fluorescent stain "sporotan" and staining protocol which aid in the identification of cryptic endospores which are otherwise mistaken as poly-β-hydroxyalkanoate granules.

Zwitterionic small molecule based fluorophores for efficient and selective imaging of bacterial endospores.

In the emerging scenario of increasing antibiotic resistance and pathogen transmission channels, the grave danger posed by bacterial endospores in critical fields like food industry, health and medicine highlights the urgent need to develop efficient probes for their detection; their sturdy and impermeable multilayer coat makes desirable methods like fluorescence imaging extremely difficult. Selective imaging of the endospores in the presence of the bacteria is even more challenging. Furthermore, it is preferable to maintain the dormant state of endospores through the imaging process, if extended monitoring is required; many of the available techniques involve lethal germination or destruction of the endospores.

Sporadic hypothyroidism-related hypokalemic paralysis: Diagnosis in a resource-poor setting.

Hypothyroidism and distal renal tubular acidosis causing hypokalemic paralysis (HP) have been described only in four female patients. HP as the initial manifestation of uncomplicated diabetes has been reported only in three young males. We report two middle-aged patients presenting with gradual-onset areflexic quadriparesis and neck flop, associated with urinary potassium losses, and recovering over 3 days.
