Research ArticleOpen accessEvery word in the titleCardiac Depression Produced by L-Arginine and Phosphodiestrase Inhibitor on Isolated Mammalian Rabbit Heart: Function of Cyclic Guanosine Monophosphate (cGMP)Hussein F. Sakr, Fahaid Al-Hashem, Mahmoud Al-Khateeb et al.Problem statement: Cyclic guanosine 3',5'-monophosphate cGMP is one the important second messengers that determines the cardiomyocyte activity and its role in healthy and diseased cardiac muscle is still controversial. We are reporting the effect of adding L-arginine, the NO donor that stimulates cGMP production and Sildenafil citrate (phosphodiestrase inhibitor) that inhibits cGMP hydrolyis on isolated rabbit’s heart to answer: Is … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 2 · 30 Jun 2010 · 8,182 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSynthesis and Calcium Channel Blocking Activity of 1, 4-Dihydropyridine Derivatives Containing Ester Substitute and Phenyl Carbamoyl GroupBassem Sadek, Khairi Mustafa Salem Fahelelbom, Laurentiu Morusciag, Sigurd ElzProblem statement: Several studies on the synthesis of new nifedipine analogs have been carried out, but the literature reveled that no study on the synthesis and calcium channel blocking activity of the substituted ester with an amide (5-phenylcarbamoyl) moiety has been reported. Approach: Six new derivatives of m-nifedipine have been successfully synthesized by substituting an ester moiety with an amide … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 8,247 accessesView PDF Cite

Research ArticleOpen accessIn the abstractToxicological Study of Hydroalcohol Leaf Extract of Acanthospermum hispidum (Asteraceae)Diallo Aboudoulatif, Dowou Salem, Badjabaissi Essotolom et al.Acanthospermum hispidum is a widely plant used in African traditional medicine. This study aims to assess cardiotoxicity and sub-chronic (28-days) oral toxicity of hydroalcohol leaf extract of A. hispidum. The sub-chronic toxicity was evaluated after administering daily oral doses of 500 and 1000 mg/kg body wt., for 28 days to the rats, biochemical and haematological assessments as well as body … …American Journal of Pharmacology and Toxicology, Vol. 15, Issue 1 · 16 Mar 2020 · 7,755 accessesView PDF Cite

InvestigationOpen accessIn the abstractEffects of Recombinant Toxin Phospholipase D in Cardiac Muscle of RatsJoao Victor Capelli Peixoto, Fernando Augusto Lavezzo Dias, Carlos Estevan Nolf Damiani et al.Loxoceles spiders gender are worldwide spread and its bites can cause dermonecrosis or even a systemic effect (hemolysis, kidney and liver injury). It is believed that phospholipase D, the main component present in the venom, could be responsible for the injury. In this study, we used a recombinant form of phospholipase D (rLiD1) and evaluated its direct and systemic effects … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 1 · 2 Jun 2015 · 6,956 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRat Cardiomyocytes Express a Classical Epithelial Beta-DefensinAnnika Linde, Gerald H. Lushington, Frank Blecha, Tonatiuh MelgarejoBeta-defensins (BDs) are classical epithelial antimicrobial peptides of immediate importance in innate host defense. Since recent studies have suggested that certain BDs are also expressed in non-traditional tissues, including whole heart homogenate, and because effector molecules of innate immunity and inflammation can influence the development of certain cardiovascular disease processes, we hypothesized that BDs are produced by cardiomyocytes as a … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 6,994 accessesView PDF Cite

Research ArticleOpen accessIn the abstractToll-Like Receptor (TLR) 2 and TLR4 Gene Expression in Canine HeartA. Linde, F. Blecha, T. MelgarejoToll-like receptors (TLRs) are archetypal pattern recognition receptors of immediate importance for an efficacious innate immune response. TLRs exhibit marked differential tissue activity and their levels within a discrete cell type can be highly dynamic. Of 13 known mammalian paralogues, three TLRs have been identified in the dog. Although cardiac TLR expression has been reported in other species, this study … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 6,921 accessesView PDF Cite
