In this paper, we prove results on enumerations of sets of Rota-Baxter words in a single generator and one unary operator. Examples of operators are integral operators, their generalization to Rota-Baxter operators, and Rota-Baxter type operators. Rota-Baxter words are certain words formed by concatenating generators and images of words under the operators. Under suitable conditions, they form ...

BACKGROUND Aim of this trial was to compare rotational atherectomy followed by balloon angioplasty (rotablation [ROTA] group) with balloon angioplasty (percutaneous transluminal coronary angioplasty [PTCA] group) alone in patients with diffuse in-stent restenosis. METHODS AND RESULTS The ARTIST study is a multicenter, randomized, prospective European trial with 298 patients with in-stent rest...

Previous results have suggested that the Ras signaling pathway is involved in learning and memory. Ras is activated by nucleotide exchange factors, such as the calmodulin-activated guanine-nucleotide releasing factor 1 (Ras-GRF1). To test whether Ras-GRF1 is required for learning and memory, we inactivated the Ras-GRF1 gene in mice. These mutants performed normally in a rota-rod motor coordinat...

OBJECTIVES The aim of present study was to evaluate some effects of Crinum zeylanicum (C. zeylanicum) on central nervous system. MATERIALS AND METHODS C. zeylanicum methanolic bulb extract (250-1000 mg/kg orally), 2 mg chlorpromazine and 4 mg diazepam /kg body weight intraperitoneally respectively were tested in mice using Irwin test, pentobarbitone-induced sleep test, spontaneous motor activ...

Myristica fatua var. magnifica (Beddome) Sinclair belongs to the family Myristicaceae. It is a tree used as an important plant to cure various diseases. In the present study the Petroleum ether, Ethyl acetate and Methanolic extracts of Myristica fatua was evaluated for its toxicity, potential analgesic, depressant and in vitro and in vivo anti-inflammatory activity. The extracts at different co...

In this study, the behavioral effects of inhalation of the essential oil of Ocimum gratissimum from Cameroon were investigated. The open field test, light/dark box test, tail suspension test and Rota-rod test were used to assess the sedative, anxiolytic-like, antidepressant-like and motor coordination effects respectively, in mice. GC and GC/MS analyses were performed to investigate the chemica...

Quinoxaline-2, 3-dione obtained from cyclocondensation reaction of o-phenylene diamine with oxalic acid was reacted with three different ketones and formaldehyde to give the corresponding Mannich bases in satisfactory yield. Their structures were confirmed by using (1)H NMR, IR, and mass analysis. In pharmacological evaluation, the synthesized compounds showed its curative effect against ethidi...

The study was designed to investigate the skeletal muscle relaxant activity of vicia faba (400mg/kg, p.o) by using rota rod apparatus. Experiments were carried out on albino mice and the animals were randomly allotted to the different control, test and standard (diazepam 4mg/kg, p.o) groups. The methanolic extract significantly reduced the fall off time (4.33sec) in comparision with the fall of...

Rota-Baxter algebras appeared in both the physics and mathematics literature. It is of great interest to have a simple construction of the free object of this algebraic structure. For example, free commutative Rota-Baxter algebras relate to double shuffle relations for multiple zeta values. The interest in the non-commutative setting arose in connection with the work of Connes and Kreimer on th...

PLACE AND DURATION OF STUDY National Institute of Child Health, Karachi, from January to June 2007. METHODOLOGY A total of three hundred children of either gender aged 1 month to 5 years, who presented wi...
