Use of Gasotransmitters for the Controlled Release of Polymer

NO is synthesized by NO synthase by conversion of L-arginine to L-citrulline in the human Polymeric carrier body. NO then stimulates soluble guanylate cyclase, from which various physiological functions are mediated in fi Hydrogen sul de a concentration-dependent manner. High concentrations of NO induce apoptosis or antibacterial responses Carbon monoxide whereas low NO circulation leads to angiogenesis. The bidirectional effect of NO has attracted considerable Crosstalk of gasotransmitters attention, and efforts to deliver NO in a controlled manner, especially through polymeric carriers, has been the Stimuli-responsive topic of much research. This naturally produced signaling molecule has stood out as a potentially more potent therapeutic agent compared to exogenously synthesized drugs. In this review, we will focus on past efforts of using the controlled release of NO via polymer-based materials to derive specific therapeutic results. -

Efficacy of intracavernosal injections seems superior to that of the intraurethral delivery of drugs, and this may explain the current larger diffusion of the former modality. Safety of these two therapeutic options is well established; however, the attrition rate with these approaches is significant and most patients eventually drop out of treatment. Newer agents with better efficacy-safety profiles and using user-friendly devices for drug administration may potentially increase the long-term satisfaction rate achieved with these therapies. Topical therapy has the potential to become a first- line treatment for erectile dysfunction because it acts locally and is easy to use. At this time, however, the crossing of the barrier caused by the penile skin and tunica albuginea has limited the efficacy of the drugs used.

Reverse Auction: a Potential Strategy for Reduction of Pharmacological Therapy Cost
Original Article Reverse Auction: A Potential Strategy for Reduction of Pharmacological Therapy Cost Sara Michelly Gonçalves Brandão, Victor Sarli Issa, Silvia Moreira Ayub-Ferreira, Samantha Storer, Bianca Gigliotti Gonçalves, Valter Garcia Santos, Nelson Carvas Junior, Guilherme Veiga Guimarães, Edimar Alcides Bocchi Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, SP - Brazil Abstract Background: Polypharmacy is a significant economic burden. Objective: We tested whether using reverse auction (RA) as compared with commercial pharmacy (CP) to purchase medicine results in lower pharmaceutical costs for heart failure (HF) and heart transplantation (HT) outpatients. Methods: We compared the costs via RA versus CP in 808 HF and 147 HT patients followed from 2009 through 2011, and evaluated the influence of clinical and demographic variables on cost. Results: The monthly cost per patient for HF drugs acquired via RA was $10.15 (IQ 3.51-40.22) versus $161.76 (IQ 86.05-340.15) via CP; for HT, those costs were $393.08 (IQ 124.74-774.76) and $1,207.70 (IQ 604.48-2,499.97), respectively. Conclusions: RA may reduce the cost of prescription drugs for HF and HT, potentially making HF treatment more accessible. Clinical characteristics can influence the cost and benefits of RA. RA may be a new health policy strategy to reduce costs of prescribed medications for HF and HT patients, reducing the economic burden of treatment.(Arq Bras Cardiol. 2015; 105(3):265-275) Keywords: Heart Failure; Pharmaceutical Preparations / economics; Competitive Bidding / economics; Budgets; Cost Savings; Heart Transplantation.

Box 1346 Ann Arbor, Ml 48106-1346 Abstract Nitric oxide (NO) has emerged as an ubiquitous signaling molecule in the central nervous system (CNS). NO is synthesised from molecular oxygen and the amino acid L-arginine (L- ARG) by the enzyme NO synthase (NOS), and the availability of L-ARG has been implicated as the limiting factor for NOS activity. Previous studies have indicated that L- ARG is localised in astrocytes in vitro and that the in vitro activation of non-N-methyl-D- aspartate (NMDA) receptors, as well as the presence of peroxynitrite (ONOO ), led to the release of L-ARG. Microdialysis was therefore used in this study to investigate whether this held true in vivo. -

Glutathione also had a potentiating effect of caspases. The kinetics of triggering apoptosis were on the cytotoxicity of NO+. This suggests that cellular different for the two redox species: NO+ required only a 2 antioxidants may play a role in protecting the cell from NO- hour exposure, whereas NO required 24 hours.
