Effect of restraint stress (RS) and its modulation by antioxidants were evaluated on elevated plus maze (EPM) and open field (OF) tests in rats. Restraint stress (RS for 1 hr) reduced the number of open arm entries, as also the time spent on open arms indicating enhanced anxiogenic response in the EPM test as compared to normal non RS group of rats. Pretreatment with ascorbic acid (100 and 200 ...

Patients with B-cell chronic lymphocytic leukemia (CLL) infrequently may develop high-grade B-cell lymphoma, or Richter's syndrome lymphoma (RS lymphoma). Such lymphomas differ from the original leukemia in both histology and clinical behavior. Studies seeking to define the clonal relationship between the cells of the two malignancies in any one patient have yielded conflicting reports. We exam...

Accumulating evidence indicate that GABA regulates activity-dependent development of inhibitory synapses in the vertebrate brain, but the underlying mechanisms remain unclear. Here we combined live imaging of cortical GABAergic axons with single cell genetic manipulation to dissect the role of presynaptic GABA(B) receptors (GABA(B)Rs) in inhibitory synapse formation in mouse. Developing GABAerg...

Background The recalcitrance of lignocellulosic biomass offers a series of challenges for biochemical processing into biofuels and bio-products. For the first time, we address these challenges with a biomimetic system via a mild yet rapid Fenton reaction and lignocellulose-degrading bacterial strain Cupriavidus basilensis B-8 (here after B-8) to pretreat the rice straw (RS) by mimicking the nat...

We performed low-frequency sound measurements on He in 98% aerogel in a magnetic field that was varied between 0 and 2130 G at a fixed pressure of 27.9 bar. We monitor the frequency of the second sound like sslowd mode, which is the manifestation of superfluidity of He in the presence of correlated disorder, and use its temperature dependence to calculate the superfluid fraction rs /r. We obser...

An endophytic bacterium, Bacillus thuringiensis GS1, was isolated from bracken (Pteridium aquilinum) and found to have maximal production of chitinase (4.3 units/ml) at 5 days after culture. This study investigated the ability of B. thuringiensis GS1 to induce resistance to Rhizoctonia solani KACC 40111 (RS) in cucumber plants. Chitinase activity was greatest in RS-treated plants at 4 days. bet...

where α ∈ Fqm is an element of order n and gcd(b, n) = 1. This is a cyclic Reed-Solomon (RS) code with dmin = n − k + 1. Adding roots at all the conjugates of { α, α, . . . , αa+(n−k)b } (w.r.t. the subfield K = Fq) also allows one to define a length-n BCH subcode over Fq with dmin ≥ n−k+ 1. Also, any decoder that corrects all patterns of up to t = b(n− k)/2c errors for the original RS code can...
