The Hycel Diagnostics Diana-5, a compact 5-part differential hematology analyzer, was evaluated in the hematology laboratory of Liège University Hospital, Belgium. Within-and between-batch precision, linearity, and absence of carryover were all excellent. All parameters were stable for 48 hours at 4 ° C and for 8 hours at room temperature. Comparability of complete blood counts to Bayer Technicon Advia 120 measurements was highly satisfactory, with the exception of the mean cell volume, which was slightly underestimated by the Diana-5 compared to the Advia 120. Comparisons of differential leukocyte counts to 400-cell microscopic differentials were excellent for neutrophils, lymphocytes, and eosinophils and were acceptable for monocytes. The efficiency of the flagging system was high for the detection of blasts and less satisfactory for the detection of immature granulocytes and atypical lymphocytes. The instrument was reliable and easy to use. [less ▲]

BACKGROUND: We have previously shown that short sessions of whole body vibration (WBV) were not able to significantly improve fall risk among nursing home residents but some trends towards an improvement of motor capacity were observed. OBJECTIVE: The objective of the present study was to evaluate the impact of 6-month training by WBV on functional and motor abilities among nursing home residents observed over a 12-month period. METHODS: Patients were randomized into two groups: the WBV group which received three training sessions every week composed of five series of 15 s of vibration at 30 Hz intensity for a period of 6 months and a control group with normal daily life. The impact of this training on the risk of falls was assessed blindly after 6 and 12 months by the Tinetti Test, the "Timed Up and Go" test and a quantitative evaluation of a 10-s walk performed with a tri-axial accelerometer. The occurrence of falls was also observed. RESULTS: 62 elderly healthy volunteers, (47 women and 15 men, mean age 83.2 +/- 7.9 years) were included in this study. There was no significant difference between the two groups regarding the Tinetti test (p = 0.75), the "Timed Up and Go" test (p = 0.19) and the Locometrix(R) test, except for the step length, measured by dual task (p < 0.01). No significant inter-group difference in the frequency of falls was observed during the 12 months of research. A total of 42 falls were recorded during the first 6 months of experimentation: 24 falls in the treated group and 18 in the control group (p = 0.60). During the next 6 months, 19 falls occurred: 8 falls in the treated group and 11 in the control group (p = 0.52). CONCLUSION: This study failed to establish the effectiveness of low doses of WBV, under the conditions used in our study, on functional and motor abilities of institutionalized elderly patients. However, given the positive results of other studies, further investigations, with modified therapeutic protocols, seem necessary to clarify the effects of WBV in the elderly. [less ▲]

Triclosan (5-chloro-2-[2, 4-dichlorophenoxy] phenol) is an antimicrobial widely used in various industrial products such as textiles, cosmetics and body care products. It is often detected in aquatic environments. The presence of the main biotransformation product, methyl TCS, indicates that this compound is not only degraded, but also persistent and accumulates in aquatic organisms. In this study, the effects of TCS on the thyroid system during embryonic and larval stages in Cyprinodon variegatus were evaluated. In particular, whole body thyroid hormone levels and the activity of deiodinases, enzymes involved in the activation of the thyroid prohormone T4, were measured. Couples of three females and two males were placed in breeding chambers designed for this experiment from which 3832 eggs were obtained by reproduction in the laboratory. Eggs were collected and maintained in seawater. Embryos were selected under a dissection microscope, randomly assigned to each of five treatment groups: Control, DMSO control (vehicle), 20 μg/L TCS, 50 μg/L TCS and 100 μg/L TCS and placed in incubation dishes (50 per dish) at 25°C. On day 6, embryos hatched and larvae were transferred to 1L dishes. The larvae were fed on artemia and on flaked fish food till day 15 post hatching when the fish were analyzed. The fertilization and survival rate, as well as the larval dry weight did not vary significantly between individuals exposed to 20, 50 and 100 μg/L TCS. T3 and T4 concentrations increased significantly in larvae exposed to 50 and 100 μg/L TCS. The study of the activity of enzymes involved in the deiodination of thyroid hormones (ORD) represents a new aspect in the study of endocrine disruption in C. variegatus. Unfortunately, we were not able to detect a net enzymatic T4 deiodination activity, most likely due to the very small amounts of protein and low specific enzyme activity in brain homogenates, carcass and liver.

OBJECTIVE: To assess the influence of age on pulmonary hemodynamics and hemorheological properties in healthy dogs. ANIMALS: 14 healthy Beagles. PROCEDURES: Dogs were placed in 2 age groups as follows: young dogs (<or= 5 years old; n = 8) and old dogs (>or= 8 years old; 6). Hematologic characteristics, plasma total protein and fibrinogen concentrations, and blood viscosity were measured. Systolic time intervals of pulmonary blood flow were recorded by pulsed-wave Doppler echocardiography. Early (E') and late (A') diastolic myocardial velocities, isovolumic contraction velocity, and systolic myocardial velocity of the free tricuspid annulus were recorded by pulsed-wave tissue Doppler imaging (TDI). Dogs were anesthetized and pulmonary arterial pressures (PAP) and cardiac output were recorded with a pediatric thermodilution Swan-Ganz catheter. RESULTS: Hemorheological measurements were not different between the 2 groups. Systolic, mean, and diastolic PAP were higher in old dogs, compared with values in young dogs; this difference was attributed to a high pulmonary vascular resistance and low arterial compliance in old dogs. Systolic time intervals of pulmonary blood flow stayed unchanged. The A' wave of the free tricuspid annulus was increased in old, compared with that young dogs, and the E':A' ratio was decreased. Pulmonary vascular resistance was inversely correlated with compliance. CONCLUSIONS AND CLINICAL RELEVANCE: The age of dogs should be taken into account when interpreting pulmonary hemodynamic results and TDI variables of right ventricular diastolic function. [less ▲]
