But its activity declines dramatically in aging cells. Nrf2 inducers -lipoic acid (LA) and sulforaphane (SFN) have been described in the dietary industries for their antioxidant effects on various cell lines. However, since little is yet known about LA’s capacity to protect skin cells from premature and extrinsic aging; our aim was to demonstrate the beneficial effect of LA on the cellular detoxification systems. On this purpose, we evaluated its effects against injuries induced by H2O2 in NHDF and its likely positive effect on the chymotrypsin-like (CT-like) activity of 20S proteasome, using SFN as a reference. The cellular content in proteins was measured, as well as the production of Reactive Oxygen Species (ROS). Also, the induction of the proteasomal protein expression was investigated. The results show that after 48 h treatment, LA significantly decreased the percentage of ROS positive cells. Also, LA decreased the level of H2O2-induced carbonylated proteins and increased the proteasomal activity. Furthermore, LA upregulated the expression of the 20S proteasome s-subunit responsible for the CT-like activity (PSMB5). Overall, both molecules enhanced cell proliferation over 8 days. So, our investigation found evidence of the higher capacity of LA to induce 20S proteasome activity with less toxicity in human fibroblasts compared to reference molecule SFN. These results tend to demonstrate that the induction of the proteasomal activity might be a part of the antioxidant potential of LA. To our knowledge, this is the first study to elucidate the capacity of LA to activate detoxification systems in human cell lines through the induction of 20S proteasome.","PeriodicalId":19875,"journal":{"name":"Pharmacology & Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84464854","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}

A comprehensive survey was sent out via Facebook, Inc., to self-identified runners to assess runners’ first response to 5 common self-care situations. The results were compared to the national average of the U.S. population who take prescription and OTC medications. What was also assessed was the relationship between average weekly miles run and the likelihood to choose OTC medications. 714 runners, residing predominately in the St. Louis, Missouri metropolitan area, completed the survey and their results were drastically different than the national average use for prescription and OTC medication in the general (non-runners) population. Approximately 30% of the runners in this study are on daily prescription medications versus a national average of 70% of the U.S. population. In each of the 5 common self-care situations, less than 50% of runners chose an OTC medication as their first option for self-care vs. the national average of 80%. Results of the study also showed that runners with a weekly mile average of 30 miles or more were less likely to choose an OTC option for self-care than runners with a weekly average of 15 miles or less. Overall, results of this survey suggest that runners are less likely to take medications and may be healthier than the average U.S. citizen overall.","PeriodicalId":19875,"journal":{"name":"Pharmacology & Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88542718","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}

Piperine is such naturally occurring alkaloid which can be considered as major bioactive phytochemical having broad spectrum of pharmacological activities. It is obtained from the most valuable ethnomedicinal spices peppercorns i.e. black pepper and white pepper, which are the fruits of the Asian vine Piper nigrum L. Because of the widespread traditional uses of this medicinal compound, present article reveals a simple and effective isolation method of bulk piperine. The novelty of this investigation is to provide an idea for utilizing such natural method of large scale commercial piperine production as API drug in spite of chemical synthesis. Piperine was isolated in a pure crystal form and characterized by its melting point, X-Ray diffraction (XRD) studies and spectral data, including two-dimensional nuclear magnetic resonance (2D-NMR) spectroscopy. Chromatographic techniques like Thin Layer Chromatography (TLC) and High Performance Liquid Chromatography (HPLC) were applied to determine the purity of the yielded piperine. It was found that piperine yield from black pepper was within 2.5% - 3.0% and from white pepper within 4.0% - 4.5% and the purity of the yielded piperine was found to be up to 98.5% for black pepper and 98.2% for white pepper. Considering this yield value and purity it is indicated that, such effective isolation method can be successfully utilized for industrial large-scale production commercially. According to the result, it can be claimed that, as a natural product the isolated piperine can also be utilized as API drug like other expensive chemically synthesized piperine in different drug formulation.","PeriodicalId":19875,"journal":{"name":"Pharmacology & Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80444592","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}

Cerebrolysin is a neurotrophic factor that improves the dendritic tree and synapses in the central nerve system after brain damage. The aim of this study was to evaluate if cerebrolysin can improve the cardiac neuropathy generated in diabetic rats. Male Sprague-Dawley rats two months old were injected with streptozotocin (70 mg/Kg/, ip). Hyperglycemia and altered cardiac rate were confirmed after eight weeks of STZ injection, and cerebrolysin treatment was started in control and diabetic rats for two months (1 ml/kg/day, ip). Body weight, heart rate, heart rate variability, arterial blood pressure, and blood glucose levels were measured. Also heart weight and levels of nitrites, NGF and VEGF were measured in left ventricle homogenates. The results show that body weight was reduced and blood glucose levels were increased significantly in diabetic rats. Cerebrolysin treatment produced no significant changes in body weight either in blood glucose level in control and diabetic rats. Cerebrolysin treatment in diabetic rats shows an improvement in the altered basal cardiac rate (306 ± 6.5 lat/min) compared to diabetic saline group (272 ± 8.9 lat/min: P < 0.05), without changes in control rats. Levels of nitrites, VEGF, and NGF in the left ventricle increased in diabetic cerebrolysin treated rats. In conclusion, the results show that cerebrolysin improves some abnormalities observed in the diabetic cardiac neuropathy in rats and suggest that could be considered an additional treatment to prevent or reduce the cardiac autonomic alterations generated in diabetes.","PeriodicalId":19875,"journal":{"name":"Pharmacology & Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91057538","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}

Etomidate shortages require providers to utilize alternative agents. The purpose of this study is to compare the safety and procedural outcomes of propofol and etomidate for RSI in the ED. Methods: This was a retrospective chart review of adult patients in the ED who received propofol or etomidate for induction during RSI. The main endpoint was hypotension, defined as a systolic blood pressure < 90 mmHg or diastolic blood pressure < 60 mmHg, within the first hour of intubation. Time to intubation, intensive care unit length of stay, hospital length of stay, and in-hospital mortality were also evaluated. Results: Two hundred and seventy five patient charts were reviewed. Of the 98 patients included, 43 patients received propofol and 55 patients received etomidate. Propofol was associated with an increased incidence of hypotension within the first hour of intubation (65.1% vs. 25.5%, p < 0.001). No difference was found in the time to intubation: ≤5 minutes (51.2% vs. 34.6%, p = 0.83). The mortality rate was 11.6% in the propofol group and 27.3% in the etomidate group (p = 0.004). There was no difference in hospital or intensive care unit length of stay between the propofol and etomidate groups (7.7 vs. 9.2 days, p = 0.23; 4.2 vs. 6.3 days, p = 0.31). Conclusion: Propofol was a safe and procedurally effective induction agent for RSI. Compared to etomidate, it was associated with an increased rate of hypotension within the first hour of intubation, with no difference in the percent of patients that required an intervention.","PeriodicalId":19875,"journal":{"name":"Pharmacology & Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78872448","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}
