Objective |
This review summarizes the current and previous data on dietary supplement (DS) use collected from participants in the National Health and Nutrition Examination Survey (NHANES), describes the NHANES dietary supplement database used to compute nutrient intakes from DSs, discussed recent developments and future direction... |
Background and History |
Since 1971, NHANES, has been collecting information on the use of DSs from participants. These data are critical to national nutrition surveillance and have been used to characterize usage patterns, examine trends over time, assess the percentage of the population meeting or exceeding nutrient recommendations, and to h... |
Rationale |
Over half of adults and about one-third of children in the United States use at least one dietary supplement in the past 30 days. Dietary supplements contribute to the dietary intake of nutrients and bioactive compounds in the US and therefore need to be assessed when monitoring nutritional status of the population and... |
Recent Developments |
With the recent development and availability of the Dietary Supplement Label Database (DSLD), a comprehensive DS database that will eventually contain labels for all products marketed in the US, NHANES DS data will be more easily linked to product information to estimate nutrient intake from DS. |
Future Directions |
Over time, NHANES has both expanded and improved collection methods. The continued understanding of sources of error in collection methods will continue to be explored and is critical to improved accuracy. |
Conclusions |
NHANES provides a rich source of nationally representative data on the usage of dietary supplements in the US.Achalasia secondary to carcinoma: manometric and clinical features. |

Studies of the ethics of medical and nursing research have focused principally on the more practical issues to do with the research process, such as informed consent and protection of subjects from harm. A more fundamental question, which is often overlooked, is whether individuals are under any sort of obligation to p... |
The direct monitoring of enzyme activities is broadly useful in many fields, ranging from biochemistry to medicinal chemistry and biology.[1] A biological process often involves multiple enzymes, which can work independently or cooperatively to control a specific biological event. Monitoring their activities can provid... |

Although anxiety and stress were two distinguished concepts, they were used confusedly by medical and psychological talks. Whereas anxiety is currently a well-known psychopathological notion, stress remains blurred and unclear. The aim of the study was of course to exhibit the relationships between stress and anxiety, ... |
: Constant current electrolysis is an important content of instrument analysis courses in high education. When this method was used to detect copper in solution, it was found that the neglected trace copper in the electrolytic residue caused the lower recovery of the copper sample. In response to this problem, the expe... |
Land flatworms usually show low ability to disperse and high endemicity, displaying many singletons in studies on land planarian assemblages. Thus, many species have been described based on specimens sampled in a single locality and/or on a few specimens. Based on phylogenetic analyses of concatenated COI and 18S rRNA... |
OBJECTIVE |
Perivascular adipose tissue (PVAT) exerts an anti-contractile effect vital to regulating blood pressure. Evidence suggests that the sympathetic nervous stimulation of PVAT triggers the release of anti-contractile factors via activation of β3-adrenoceptors. Therefore it was decided to examine β3-adrenoceptor function in... |
DESIGN AND METHOD |
Electrical field stimulation (EFS) of healthy and obese mouse mesenteric arteries (<200 μm, +/-PVAT) were characterised using wire myography (0.1-30 Hz, 20V, 0.2ms pulse duration, 4s train duration). To demonstrate the release of an anti-contractile factor in health, the solution surrounding stimulated exogenous PVAT w... |
RESULTS |
Healthy PVAT elicits an anti-contractile effect which was lost in obesity. Inhibition of β3-adrenoceptors significantly reduced the anti-contractile effect, whereas activation of β3-adrenoceptors in obese PVAT using CL-316,243 did not restore function. Solution transfer from stimulated healthy exogenous PVAT to a -PVAT... |
CONCLUSIONS |
These results demonstrate that healthy PVAT releases an anti-contractile factor via activation of β3-adrenoreceptors, which downstream triggers the release of NO. In obesity, the anti-contractile effect is lost and cannot be restored by β3-activation, but is restored by activation of NOS. This suggests that in obesity ... |

Based on the quarter car linear model, linear optimal control theory is used to calculate the feedback and feedforward gains. These gains are used in both linear a... |
BACKGROUND |
HIV positive children may be prone to developing Dental Caries due to prolonged and frequent use of sucrose containing medications and poor feeding practices. |
OBJECTIVE |
To determine the caries status of primary and permanent dentition in HIV positive Nigerian children using dmft/DMFT indices. |
METHODS |
One hundred and twelve HIV positive children aged 4 months to 13 years attending two dedicated HIV outpatient clinics were examined for dental caries of primary and permanent dentition using the WHO criteria. Carious lesions were recorded using the dmft and DMFT indices in the primary and permanent dentition respective... |
RESULTS |
Forty four [39.3%] of the 112 children examined had dental caries mainly in the primary dentition in 96.7% of the cases. Mean dmft was 1.15 +/- 1.88, mean DMFT was 0.17 +/- 0.57. Dental caries was not significantly associated with the immune status of HIV positive children; chi2 = 2.58, P = 0.275. |
CONCLUSIONS |
Dental caries experience in the primary dentition of these HIV positive children was greater than in the Nigerian paediatric population. Dental caries prevalence in these HIV positive children although lower than that seen in developed countries was however higher than in other reports of healthy Nigerian children. The... |
