This study concluded that BU samples treated with a solution of 5% phenol in 4% ammonium sulphate [...] conventional method was 58% (46/80) smears. The highest positivity rate of 57/80 (%) was by protocol 7 (5% phenol in 4% ammonium sulphate (PhAS) and concentrated by overnight gravitational sedimentation). The

Still, in air pollution epidemiology, ambient PM2.5 levels may be more appropriate exposure estimates than total personal PM2.5 exposure, since the latter reflects a mixture of indoor and outdoor [...] as exposure surrogates in air pollution epidemiology, we considered four indicator groups: (1) PM2.5 total mass concentrations, (2) sulfur and potassium for regional air pollution, (3) lead and bromine [...] Furthermore, within-city variability of fine particle levels was...

CONCLUSIONS: Simultaneous carbimazole reduces [...] Radioiodine target doses between 33 and 839 Gy were applied. Overall, the euthyroidism rates were 16.5% and 64.8%, while the hypothyroidism rates were 37.6% and 14.8% in Graves' disease and toxic nodular [...] goitre, respectively. The success rate with simultaneous carbimazole (median dose...

Risk was lower [...] against either serovar. While in sheep meat workers, the annual infection risk was 11.3% (95% CI 8.5% to 14.8%), in deer meat workers it was 0% (95% CI 0.0% to 10.9%) and in those processing beef cattle

Cattle aged 5-8 years had higher [...] seropositivity than those aged=4years (OR=3.5). Seropositivity in cattle was associated with having joint hygromas (OR=9), sharing pastures with small ruminants (OR=5.8) and contact with pastoralist herds (OR=11
