the present study introduces a new technique of homotopy perturbation method for the solution of systems of fractional partial differential equations. the proposed scheme is based on laplace transform and new homotopy perturbation methods. the fractional derivatives are considered in caputo sense. to illustrate the ability and reliability of the method some examples are provided. the results ob...

distribution of urea in the ocean and the An automated method for the determination use of 15N-labeled urea enrichment techof urea in seawater, adapted to a Technicon AutoAnalyzer, is sensitive enough to detect niques require a method that is rapid, urea at the 0.05 pg-atom urea-N liter-l level. sensitive, and convenient for use at sea. An adaptation of the diacetyl monoxime The importance of u...

The reductive metabolism of 2-amino-4-(5-nitro-2-furyl)thiazole (ANFT), a rat urinary bladder and forestomach carcin ogen, was examined in vitro using rat liver tissues. ANFT was reduced by rat liver microsomes or cytosol on anaerobic incu bation with reduced nicotinamide adenine dinucleotide phos phate. The intermediate(s) produced during the microsomal reduction bound to microsomes and to exo...

Human platelets take up and metabobound FFA. These findings suggested Iize long-chain free fatty acids (FFA). that a large portion of the platelet FFA Experiments in which platelets were uptake might be associated with the loaded with ‘4C-palmitate, homogenplatelet surface. Radioautography with ized, and then fractionated indicated electron microscopy using 3H-palmilarge amounts of membrane-bou...

Cultured leukemic T-lymphoblasts, incubated in the pres ence of inhibitors of adenosine deaminase, are exquisitely sensitive to growth inhibition by deoxyadenosine. An analogy between this phenomenon and human combined immunodefi ciency disease associated with inborn adenosine deaminase deficiency and the use of inhibitors of adenosine deaminase in the management of T-cell acute lymphoblastic l...

colleagues [1] demonstrated that, compared with the Macintosh direct laryngoscope (MDL), the C-MAC videolaryngoscope (C-MAC) improved laryngeal view and achieved a higher intubation success rate on first attempt in patients with predictors of difficult intubation in the ICU. In the Materials and methods, however, the authors did not mention what position the patient’s head was placed during lar...

i.-Asparaginase is a chemotherapeutic agent that is also immunosuppressive, inhibiting both the cellular and hu moral responses. This study deals with the effects of the enzyme on lymphocyte surface receptors to the mitogen concanavalin A. We previously reported that short incu bation of lymphocytes with L-asparaginase leads to a de creased binding of the mitogen to their surface. We now re por...
