context the occurrence of intradialytic hypotension (idh) during hemodialysis (hd) continues to be a main problem in patients with esrd (end-stage kidney disease). it also negatively affects health-related quality of life. we aimed to determine vasopressin effect in decreasing idh. evidence acquisition we reviewed clinical and experimental literature in a variety of sources, including pubmed, c...

The morphology of the material surrounding Her-big Ae/Be stars is still a topic of debate. Distinct models with different geometry and optical thickness are found to be compatible with the observed IR excess. This indicates that it is not possible to resolve this question by only looking at the fluxes. Therefore, this paper compares three known Herbig Ae/Be stars with very similar energy distri...

On the basis of Coravel observations, we present orbital parameters for 10 spectroscopic-binary systems including an evolved star, namely HD 13530, HD 28591, HD 47415, HD 78414, HD 123999, HD 153751, HD 174881, HD 179094, HD 212280 and HD 217188. The most significant result is related to HD 13530, for which we have found an orbital period of 1575.48±1.63 days and an eccentricity of 0.8815. Such...

Osmolality is an expression of the number of particles in a given weight of solvent (mOsm). Measured osmolality is determined by the osmometer, and calculated osmolality is estimated by 2xNa + UN/2.8 + glucose/18. The difference between measured and calculated osmolality is the osmolal gap. The purpose of the present study is to determine the measured and the calculated osmolality and the osmol...

Rats were injected subcutaneously with 2,5-hexanedione (2,5-HD 2.6 m mol/kg) alone (HD group) or with 2,5-HD and methyl ethyl ketone (MEK) (2.6 m mol/kg of each agent, HD&MEK group) or with 2,5-HD 2.6 m mol/kg and 5 times that dose (13.0 m mol/kg) of MEK (HD&5MEK group). The concentration of 2,5-HD in serum and in the sciatic nerve was determined 0.5, 1, 2, 4, 8, and 16 h after administration. ...

CONTEXT The frequency of occurrence of attention-deficit/hyperactivity disorder (AD/HD) is in dispute. This uncertainty has contributed to the concern that too many children in the United States are being treated with stimulant medication. OBJECTIVES To determine the cumulative incidence of AD/HD in a population-based birth cohort and to estimate the prevalence of pharmacologic treatment for ...
