There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

### 1.1 Introduction

Atherosclerotic cardiovascular disease (CVD) is a chronic disorder developing insidiously throughout life and usually progressing to an advanced stage by the time symptoms occur. It remains the major cause of premature death in Europe, even though CVD mortality has …

admission. This proportion could already be greater in some parts of the country and may increase if referrals of cases of self-poisoning increase faster than the facilities for their assessment and management. The provision of social work and psychiatric expertise in casualty departments may be one means of preventing unnecessary medical admissions without risk to the patients. Dr Blake's and Dr Bramble's figures do not demonstrate, however, that any advantage would attach to medical teams taking over assessment from psychiatrists except that, by implication, assessments would be completed sooner by staff working on the ward full time. What the figures actually suggest is that if assessment of overdoses were left to house doctors there would be an increase in admissions to psychiatric units (by 19°U), outpatients (by 5O°'), and referrals to social services (by 140o). So for house doctors to assess overdoses would provide no economy for the psychiatric or social services. The study does not tell us what the consequences would have been for the six patients who the psychiatrists would have admitted but to whom the house doctors would have offered outpatient appointments.

Punicalagin exerts neuroprotective activity by improving AMP-activated kinase (AMPK) and mitochondrial Krebs cycle. AMPK and Krebs cycle metabolites regulate 5-hydroxymethylcytosine (5hmC) via acting on ten-eleven translocation (TET) enzymes. Therefore, we hypothesized that punicalagin inhibits diabetes-related neuronal apoptosis by upregulating 5hmC in the diabetic mouse brain. C57BL/6J mice aged 8 weeks were randomly separated into five groups (n = 10), normal control (NC), diabetes mellitus (DM), resveratrol (RES), low-dose punicalagin (LPU), and high-dose punicalagin (HPU). Compared with other groups, the neuronal apoptosis rate was significantly higher and the 5hmC level of the cerebral cortex was significantly lower in the DM group. The levels of TET2 and P-AMPKα/AMPKα were significantly lower in the DM group than in both LPU and HPU groups. The ratio of (succinic acid + fumaric acid)/α-ketoglutarate was significantly higher in the DM group than in other groups. The present results suggest that punicalagin upregulates 5hmC via activating AMPK and maintaining Krebs cycle homeostasis, thus inhibiting neuronal apoptosis in the diabetic mouse brain.

The bioavailability of diacylglycerol (DAG) microemulsion (DAGM) was investigated in rats. The fatty acid (FA) concentrations in the serum of all rats at 0, 6 and 24h and in feces after oral administration of DAGM and DAG oil were examined. The results showed that the FA concentration of the DAGM group was significantly higher than that of the DAG oil group at 6 h after treatment. The digestibility was detected in rats for 2 weeks. During this period, there was no significant difference in the body weight between the two groups. However, the total food consumption of rats treated with DAGM was evidently less than that treated with DAG oil (P = 0.006). The fat absorption of DAGM was significantly higher than that of DAG oil. The contents of 18:1, 18:2n–6 and 18:3n–3 were significantly lower in the DAGM group than that in the DAG group in fecal lipids. In conclusion, DAGM seems to be a good candidate for enhancing the bioavailability of DAG.



PRACTICAL APPLICATIONS

With the advantage of enhancing the bioavailability of active compounds, microemulsion is widely used as a delivery vehicle for actives in pharmaceutics. However, the application of microemulsion technology in common foods has not been prevalent. Diacylglycerol (DAG) oil is an edible and functional oil, the beneficial effects of DAG oil have been shown on both animal and human studies. We have prepared a microemulsion containing DAG oil and investigated the bioavailability of DAGM. Compared with DAG oil, DAGM showed the advantage of high absorption of DAG. The results obtained here could provide a new application of DAG oil in food industry. Furthermore, in the case of achieving the same effect, the excellent absorption implied that DAGM can reduce DAG oil dosage, thereby reducing the economic costs.

Diacylglycerol (DAG) supplementation has been shown to be associated with the reduction of fasting serum triacylglycerol (TAG) concentration, although the extent of the association is uncertain. We quantitatively examined the effect of dietary DAG on fasting serum TAG concentration by conducting a meta-analysis of randomized controlled trials. Potential papers were searched from electronic databases of Medline, Embase and Cochrane Library. Information was extracted and the net change of fasting serum TAG concentration was used as the primary outcome to examine the effect of DAG in Review Manager 4.2. Six papers with seven independent studies (298 subjects) were included into the statistic pooling. Meta-analysis with random effect model showed that DAG did not reduce the fasting serum TAG concentration (WMD: -0.07 mmol/L; 95% CI: -0.21 to 0.08 mmol/L; P = 0.37). Sensitivity analysis indicated the robustness of overall results. Fail-safe number analysis indicated that 18 studies with positive effect were necessary to reverse the reported non-significant efficacy of DAG. Weight estimation analysis indicated that the effect of DAG was influenced to some extent by the initial fasting serum TAG concentration. In conclusion, DAG supplementation did not reduce the fasting serum TAG concentration significantly compared with TAG, but some effects were suggested in diabetic patients with hypertriglyceridemia.

Effect of Diacylglycerol Supplementation on Fasting Serum Triacylglycerol Concentration: a Meta-Analysis

Objective
Use epidemiological approaches to investigate the correlation between the siesta and blood pressure.


Method
From March 1st, 2011 to June 30th 2013, a total of 950 people were collected from East Jiaozhou Qingdao region using variable sampling methods including stratified method, the entire group method, random and proportional methods. Medical professionals conducted a person-to-person survey, collecting the data and inputting it into computers, after which a database was established using STATA 12.0. We analyzed the correlation between the siesta time and blood pressure/hypertension by using rank correlation method (Spearman). Logistic regression method was used to analyze the relationship between high blood pressure and different time and habit of the siesta after adjusting age, sex and BMI.


Results
There was a negative correlation between the time of siesta and the systolic pressure with r=-0.18, P 25 kg/m2 and no siesta habits.


Conclusions
The time of siesta is negatively correlated to the systolic pressure, rather than the diastolic pressure, and it can generally reduce the incidence of hypertension. The relative risk factors of hypertension are more than 60-year-old, BMI >25 kg/m2 and no siesta habits in all four seasons. We recommend that take a nap a day, or it might be even better for systolic blood pressure to take longer siesta.
