Let A and B be bounded linear operators on a Banach space such that ABA = A2 and BAB = B2. Then A and B have some spectral properties in common. This situation is studied in the present paper. 1. Terminology and motivation Throughout this paper X denotes a complex Banach space and L(X) the Banach algebra of all bounded linear operators on X. For A ∈ L(X), let N(A) denote the null space of A, an...

The BAV component of HL23V virus (HL23V-BAB) hybridized to DNA from different Baboon tissues and appears to be an endogenous Baboon virus. Competition hybridization studies show that HL23V-BAB is closely related to viruses isolated from various Baboon species: P. hamadrys, P. papio, and P. cynocephalus. Competition hybridization studies also show that normal Baboon tissues contain more copies o...

Salinicoccus sp. BAB 3246 is a halophilic bacterium isolated from a marine water sample collected from the coastal region of Gujarat, India, from a surface water stream. Based on 16sRNA sequencing, the organism was identified as Salinicoccus sp. BAB 3246 (Genebank ID: KF889285). The present work was performed to determine the whole genome sequence of the organism using Ion Torrent PGM platform ...

PURPOSE To evaluate the function of the blood aqueous barrier(BAB) in the eyes with silicone oil emulsification (SOE). METHODS Protein concentrations, expressed in albumin equivalents,were determined in aqueous humor of the eyes with SOE in 11 consecutive patients by means of proton nuclear magnetic resonance (1H NMR) spectroscopy. Correlations with various clinical factors were studied. RE...

Disruption of the central nervous system (CNS) barriers is one of the major pathophysiological consequences of bacterial meningitis. The increase in the permeability of the CNS barriers caused by the disruption is thought to contribute to the development of adverse neurological outcomes. We have established a method by which the CNS barrier permeability can be demonstrated by the gadolinium-enh...

Anterior chamber paracentesis disrupts the blood aqueous barrier (BAB) of rabbits and nonhuman primates, but the magnitude and duration of breakdown in monkeys has not been clarified. We have studied anterior chamber paracentesis in cynomolgus monkeys as a potential model of postoperative BAB breakdown. The effect of a single paracentesis upon fluorescein sodium concentration in the anterior ch...
