Conclusions Appropriately developed internal models produce relatively unbiased estimates of treatment effect across the spectrum of risk. When estimating treatment effect, internally developed
risk models using both treatment BIRB 796 supplier arms should, in general, be preferred to models developed on the control population.”
“Congenital arteriovenous malformations are a well-described cause of neonatal heart failure. Fistulous connections are typically intrahepatic or intracranial. We present a case of a neonate with an intrathoracic arteriovenous malformation between the subclavian artery and superior vena cava resulting in florid neonatal heart failure. This unusual fistulous connection has only rarely been reported in the literature, and in those reports, it has not resulted in neonatal heart failure.”
“Purpose: To develop and validate a dissolution
test method for tablets containing 80 mg of drotaverine hydrochloride (DRT) and 250 mg of mefenamic acid (MEF).
Methods: Sink conditions, drug stability and specificity in different dissolution media were tested to optimize a dissolution test method using a USP paddle type dissolution test apparatus set at a speed of 50 rpm. The dissolution medium consisted of 900 ml of phosphate buffer (pH 6.8) containing 0.25% w/v Z-VAD-FMK molecular weight cetrimide at 37 +/- 0.5 degrees C and 45 min time-point. To determine both drugs simultaneously, a first derivative UV spectrophotometric method was developed and validated. Drug release was analyzed by first derivative UV method at 253.8 nm and
304 nm for DRT and MEF respectively. The dissolution method was validated as per ICH guidelines.
Results: The two brands each showed 98% of drug release for both drugs when the developed dissolution method was used. The regression plot was linear in the concentration range 4 – 24 mu g/mL for each of the drugs and regression coefficient (r(2)) was greater than 0.999 for each drug. Relative standard see more deviation (% RSD) for precision and accuracy of proposed method was < 2.
Conclusion: The proposed dissolution method is simple, cost-effective, precise, accurate and specific. It can be successfully employed in routine quality control of DRT and MEF combination tablets.”
“Contents Among the modifications that occur during the neonatal period, pulmonary development is the most critical. The neonate’s lungs must be able to perform adequate gas exchange, which was previously accomplished by the placenta. Neonatal respiratory distress syndrome is defined as insufficient surfactant production or pulmonary structural immaturity and is specifically relevant to preterm newborns.
