Effect of Laurus nobilis on bacteria and human transforming growth factor-ß1.

OBJECTIVE: In this study, we aimed to determine the phenolic compounds, the antibacterial activity of extract from Laurus nobilis leaves, and its possible effect on transforming growth factor-ß1 expression level in peripheral blood mononuclear cells. METHODS: The phenolic components of Laurus nobilis were identified by the high-performance liquid chromatography method. The antibacterial activity of this extract was determined by disk diffusion and broth microdilution methods. The transforming growth factor-ß1 expression was analyzed using the RT-qPCR method. RESULTS: Epicatechin was found in the highest amount and o-coumaric acid in the lowest amount. The half-maximal inhibitory concentration (IC50) was determined to be 55.17 µg/mL. The zones of inhibition and minimum inhibitory concentration for Staphylococcus aureus, Enterococcus faecalis, and Klebsiella pneumoniae were 15, 14, and 8 mm and 125, 250, and 1000 µg/mL, respectively. The change in transforming growth factor-ß1 expression levels was found to be statistically significant compared with the control groups (p<0.0001). CONCLUSION: Laurus nobilis extract was found to be effective against bacteria and altered the expression level of transforming growth factor-ß1 in peripheral blood mononuclear cells.

Which one predicts mortality better in acute ischemic stroke: negative vs positive acute-phase reactants.

AIM: The aim of the study is to investigate the relationship between negative acute-phase reactants and positive acute-phase reactants with in-hospital mortality in patients diagnosed with acute ischemic stroke (AIS) in the emergency department (ED). METHODS AND MATERIALS: Patients aged 18 and older who presented to the ED of a tertiary hospital with AIS were included in the study. Demographic and clinical characteristics, laboratory parameters, acute-phase reactants, National Institutes of Health Stroke Scale (NIHSS), and outcome data of the included patients were recorded on a standard data form. RESULTS: A total of 588 patients were included in the study. When the in-hospital mortality of patients was examined, the mortality rate was 17.7%. In the analysis for predicting mortality, it was determined that albumin had the highest predictive power between the area under the curve (AUC) and the determined predictive values (AUC: 0.759, 95% CI 0.707-0.810, p < 0.001). The analyses of the study data revealed that albumin (<0.001) and TF (p = 0.049), which are negative acute-phase reactants, were independent predictors of mortality. According to our study data, in patients with AIS, for each unit decrease in albumin level at the time of ED admission, the risk of mortality increased by 0.868 times, and for each unit decrease in TF level, the risk of mortality increased by 0.593 times. CONCLUSION: According to the study data, albumin and TF levels, which are negative acute-phase reactants, are independent determinants of in-hospital mortality in patients with acute ischemic stroke in the emergency department.

Effect of Laurus nobilis on bacteria and human transforming growth factor-β1

SUMMARY OBJECTIVE: In this study, we aimed to determine the phenolic compounds, the antibacterial activity of extract from Laurus nobilis leaves, and its possible effect on transforming growth factor-β1 expression level in peripheral blood mononuclear cells. METHODS: The phenolic components of Laurus nobilis were identified by the high-performance liquid chromatography method. The antibacterial activity of this extract was determined by disk diffusion and broth microdilution methods. The transforming growth factor-β1 expression was analyzed using the RT-qPCR method. RESULTS: Epicatechin was found in the highest amount and o-coumaric acid in the lowest amount. The half-maximal inhibitory concentration (IC50) was determined to be 55.17 μg/mL. The zones of inhibition and minimum inhibitory concentration for Staphylococcus aureus, Enterococcus faecalis, and Klebsiella pneumoniae were 15, 14, and 8 mm and 125, 250, and 1000 μg/mL, respectively. The change in transforming growth factor-β1 expression levels was found to be statistically significant compared with the control groups (p<0.0001). CONCLUSION: Laurus nobilis extract was found to be effective against bacteria and altered the expression level of transforming growth factor-β1 in peripheral blood mononuclear cells.

Predictors of 30-day mortality in patients diagnosed with hepatic encephalopathy on admission to the emergency department.

BACKGROUND: The aim of this study is to compare the laboratory findings and disease severity scores of patients diagnosed with hepatic encephalopathy (HE) in the emergency department (ED) to predict 30-day mortality. METHOD: The patients over 18 years old and diagnosed HE in the ED of a tertiary hospital were included in the study. Demographic and clinical characteristics, laboratory parameters, predisposing causes and outcomes of the patients included in the study were recorded in the data form. Severity of liver disease was assessed by Child Pugh Score (CPS), End-stage liver disease model (MELD), MELD-Na and MELD-Lactate scores. RESULTS: Two hundred fifty-four patients diagnosed with HE were included in the study. 59.1% of the patients were male. The mean age of the patients was 65.2 ±â€…12.6 years. The mortality rate of the patients was 47.2%. When the receiver operating characteristic (ROC) analysis, which determines the predictive properties of laboratory parameters and disease severity scores, was examined, the area under curve value of the MELD-Lactate score (0.858 95% CI 0.812-0.904, P  < 0.001) was the highest. Binary logistic regression analysis for the estimation of patients' 30-day mortality showed that CPS and MELD-Lactate scores and blood ammonia and B-type natriuretic peptide levels were independent predictors of mortality. CONCLUSION: According to the study data, MELD-Lactate and BNP levels in patients diagnosed with HE in the ED may help the clinician in the prediction of 30-day mortality in the early period.

Effect of different production techniques on bioactive compounds and antioxidant capacity of einkorn (Triticum monococcum L.) and durum (Triticum turgidum subsp. durum) bulgur.

BACKGROUND: The influence of cooking (traditional, microwave, autoclave) and drying techniques (microwave and hot air) on bioactive compounds in the production of einkorn and durum bulgur were investigated. Total phenolic content (TPC), total yellow pigment (TYP), total antioxidant capacity (DPPH• , ABTS•+ , FRAP), soluble free (SF), soluble conjugated (SC) and insoluble bound (IB) phenolic acid contents of the samples were determined. RESULTS: For both wheats, a significant amount of antioxidant capacity was preserved after bulgur production. TPC was found to be higher in einkorn but it was exposed to greater loss during bulgur production than durum. The amount of TYP was found to be two-fold higher in einkorn than in durum. Ferulic acid was recorded as the most phenolic acid, and chlorogenic was the least phenolic acid in both wheats. The maximum loss during bulgur production was determined in the SC fraction for einkorn and in the SF fraction for durum. CONCLUSION: In respect of the results of the analysis, microwave cooking + hot air drying treatment could be favourable for bulgur production for both wheats. © 2016 Society of Chemical Industry.

Poisoning by mad honey: a brief review.

Several plants of the Ericaceae family produce grayanotoxins which can poison humans. The best-known of these intoxications involves the eating of 'mad honey (deli bal in Turkish)' contaminated by Rhododendron nectar grayanotoxins. Accounts of mad honey intoxication date back to 401 BC. It is still one of the common food intoxications encountered for humans and livestock in Turkey. Mad honey intoxication's symptoms are dose-related. In mild form, dizziness, weakness, excessive perspiration, hypersalivation, nausea, vomiting and paresthesias are present and close follow-up is enough. However, severe intoxication may lead to life threatening cardiac complications such as complete atrioventricular block that can be treated intravenously. In this review, properties and sources of grayanotoxins, their detection methods and mad honey intoxication are discussed.
