This study has allowed not only to establish the list of consumed fungal sorts by those populations, but also to estimate the daily consumed fungal biomasses by each ethnical group. The study has revealed a significant difference between a numbers of taxa and the quantity of mushrooms consumed by various ethnical groups: the Pygmies of the area who live especially by hunting and fishing consumed 96% of the recorded taxa with some high mushrooms quantities (around 3 kg/day/family);the Bantus who live nearby Pygmies also consumed some high mushrooms quantities (around 2 kg/day/family) but a low taxa number (56% of taxa counted by the Fang;69% by the Kota;39% by the Kwele);on the other hand, the Bantus living nearest the Pygmies consumed a high taxa number as much as Pygmies (around 90% of taxa counted) but eat a lower mushrooms quantities than theirs distant congeners Pygmies (around 800 g/day/family).展开更多

Methods: Cross-analysis of anthropometric data, clinical and laboratory 273 indigenous subjects including 54 patients with cardiovascular disease (CVD) and 183 without CVD, aged 29 to 69 years. The cardiovascular risk stratification table WHO/ISH 2003 was used to assess overall cardiovascular risk level. Multiple logistic regression was used to assess the independent determinants of cardiovascular risk using the global left ventricular hypertrophy as a marker. Results: Fifty-four subjects had cardiovascular disease (CVD), including 31 women (36.7%). They were aged 51.9 ± 12.4 years (p < 0.05) and showed a high blood pressure in short-long (100 ± 77 vs 32 ± 48 months;p < 0.001). It was also found a pulse pressure, PPO (58 ± 8 vs 51 ± 4 mmHg). In multivariate analysis, HDL-C levels, fasting glucose, age greater than 50 years and the higher parity or equalizes to 5 among women have emerged as key determinants of CVD risk. Conclusion: Whatever the stage, arterial hypertension in this study is associated at the risk of cardiovascular diseases (CVD) high at the Pygmies of Congo, emphasizing the need for a more aggressive follow-up strategy.展开更多

The properties of ground states are calculated in the Skyrme Hartree–Fock with the Bardeen–Cooper–Schrieffer approximation to take into account the pairing correlation. The quasiparticle random phase approximation （QRPA） method is used to explore the properties of excited dipole states. In the calculations the SLy5 Skyrme interaction is employed. In addition to the giant dipole resonances, pygmy dipole resonances （PDR） are found to be located in the energy region below 10 MeV in both ^17,18Ne. The strength and transition density show that the low-lying states are typical PDR states. However, analyzing the QRPA amplitudes of proton and neutron 2 quasiparticle （2qp） configurations for a given low-lying state in ^17,18Ne, we find that the PDR state is less collective, more like a single 2qp excitation.展开更多
