background: precursor b-acute lymphoblastic leukemia (precursor b-all) oc-curs due to the uncontrolled proliferation of b-lymphoid precursors arrested at a par-ticular stage of b-cell development. precursor-b-all is classified mainly into pro-b-all, common-all and pre-b-all. the common acute lymphoblastic antigen cd10 is the marker for common-all. objective: this study was aimed to examine the ...

Aluminosilicate gel precursor having mullite composition was synthesized from inorganic salts of aluminum and silicon by employing the sol-gel method. Chemical analysis, surface area and bulk density measurements were performed to characterize the dried gel. The course of the mullitization was examined by FT-IR analysis which confirmed the diphasic nature of the gel. ...

Surface ozone (Surface O3)is a secondary pollutant and there are only limited studies on ozone in South India. Studies have revealed a strong correlation between higher ozone levels and warmer days. Surface O3 along with its precursors like NO2, CO and CH4 are being measured at Kanyakumari (8.0780° N, 77.5410° E), TamilNadu, India and in this paper we present the summer time variation of ozone ...

1. Staphylococci activated by rapid growth in the presence of excess O(2) and subsequently brought to a resting state by storage in Locke's solution at 5 degrees C. produce a significant rise in [phage] when added to phage-containing solutions. 2. For satisfactory activation the staphylococci require a period of active growth in the presence of oxygen. Activation proceeds best on the acid side ...

In the MyD88 family of cytosolic adaptor proteins, the newest member is the group's black sheep, according to Kim et al. (page 2063). Whereas most MyD88 proteins turn on anti-pathogen responses within myeloid cells, the rebel, MyD88-5, instigates cell death within neurons. MyD88-1–4 all respond to Toll-like receptor (TLR) activation in leuko-cytes and stimulate innate immune responses. MyD88-5,...

Intracellular trafficking and proteolytic processing of amyloid precursor protein (APP) have been the focus of numerous investigations over the past two decades. APP is the precursor to the amyloid -protein (A ), the 38–43-amino acid residue peptide that is at the heart of the amyloid cascade hypothesis of Alzheimer disease (AD). Tremendous progress has been made since the initial identificatio...

Ngô Bao Châu recently won a Fields Medal for his work on the Fundamental Lemma, conjectured by Langlands many years ago. But the relationship between the result proved by him and Langlands’ original conjecture might not be so clear to someone who has not followed the development closely. The original idea involvedwhat Langlands calls endoscopy—to explain harmonic analysis on reductive groups ov...

The Stober process is frequently used to prepare silica-coated iron oxide nanoparticles. This is usually achieved by seeding a reaction mixture consisting of water, ethanol and a catalyst with iron oxide particles and adding a silica precursor. The hydrolysis and condensation of precursor monomers results in the deposition of a silica layer on iron oxide particles. However, this process is acco...

In this study, different samples of Niobium and Vanadium co-doped titania  thin films (5-10-15 mol% Nb and 5-10-15 mol% V) were prepared via sol−gel dip coating method, using niobium chloride as niobium precursor, ammonium metavanadate as vanadium precursor, and titanium (IV) butoxide (TBT) as titanium precursor. The effects of doping amount on the structural, optical, and photo-catalytic prope...
