Conventional cancer treatment involves the use of surgery and cytotoxic chemotherapy and/or radiotherapy, which have the potential of harming normal, otherwise healthy, non-neoplastic cells. Newer forms of therapy such as immunotherapy and gene therapy have shown initial promise, but still require better ways to limit exposure to cancerous lesions in the body. As a result drug delivery systems have been developed in attempts to deliver therapeutics specifically to the target lesion site. One recent drug delivery system has revolved around the use of chitosan nanoparticle technology, where therapeutics are encapsulated into nanoparticles and targeted to tumours.\u0000\u0000\u0000SUMMARY\u0000Though few, attempts at encapsulating therapeutics such as deoxyribozymes and small or short interfering RNA have been optimistic and encouraging.","PeriodicalId":366080,"journal":{"name":"The Journal of pharmacy and pharmacology","volume":"61 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129687724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After 3 months, spatial acquisition and spatial retention were measured using the Morris water maze. Swim time, swim distance, swim speed, quadrant time and platform crossing were recorded. Spine synapse density in the hippocampus was examined by transmission electron microscopy. The expression of synaptophysin P38 (P38) mRNA was examined by real-time PCR and the protein expression of P38 was examined by Western blot.\u0000\u0000\u0000KEY FINDINGS\u0000In spatial acquisition and spatial retention, the BWS group functioned significantly better than the control group. Ultrastructural observation of the hippocampus showed that BWS significantly increased spine synapse density compared with the ovariectomised group. In addition, BWS significantly increased P38 mRNA and protein expression in the hippocampus. Thus, the positive effect of BWS on learning and memory in rats was associated with increased spinal synapse density and increased P38 mRNA and protein expression in the hippocampus following menopause-induced injury.\u0000\u0000\u0000CONCLUSIONS\u0000These results suggest that BWS could improve cognitive ability following menopause-induced impairment of learning and memory.","PeriodicalId":366080,"journal":{"name":"The Journal of pharmacy and pharmacology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115950384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of quercetin was also evaluated after administration of phentolamine plus propranolol (to block alpha- and beta-adrenergic receptors), NG-nitro-L-arginine methyl ester (to block nitric oxide synthesis), capsaicin (to desensitise sensory C fibres), alpha-chymotrypsin (a proteolytic enzyme that rapidly degrades vasoactive intestinal peptide), SR140333 and SR48968 (tackykinin NK1 and NK2 receptor antagonists, respectively).\u0000\u0000\u0000KEY FINDINGS\u0000Quercetin produced a concentration-dependent inhibition of contractions induced by both carbachol and electrical field stimulation. However, quercetin was more active in inhibiting the contractions produced by electrical field stimulation than those induced by carbachol, suggesting a presynaptic site of action (in addition to a postsynaptic effect, as revealed by the inhibitory action of quercetin on carbachol-induced contractions). The inhibitory effect of quercetin on contractions induced by electrical field stimulation was unaffected by phentolamine plus propranolol, SR 140333 and SR 48968, capsaicin treatment or by the proteolytic enzyme alpha-chymotrypsin.

DPP-4 is expressed in various tissues but soluble DPP-4 is also present in plasma. Therefore, binding to soluble DPP-4 may influence the pharmacokinetics of BI 1356. Plasma protein binding of BI 1356 was determined in vitro for wild type mice and rats and the results compared with those for DPP-4 knockout mice and DPP-4 deficient Fischer rats. In addition, protein binding of BI 1356 was examined in plasma from healthy human volunteers and renal excretion of the compound in the DPP-4 knockout mice was compared with that occurring in wild type mice.\u0000\u0000\u0000KEY FINDINGS\u0000The results showed that BI 1356 exhibited a prominent concentration-dependent plasma protein binding due to a saturable high affinity binding to the DPP-4 target in plasma.
