microvesicular steatosis is a potentially severe manifestation of valproic acid hepatotoxicity due to an acquired impairment of mitochondrial function tests currently used to investigate mitochondrial fonction are cumbersome and cannot be used routinely we report on a noninvasive breath test using cmethionine for estimation of mitochondrial function in a case of pure severe valproic acid overdoseinduced microvesicular changes the initially abnormal breath test improved together with the recovery of CL failure in conclusion this observation suggests that the MET breath test may provide a noninvasive estimate of hepatic mitochondrial function in vivo | MEDAL |
broiler chickens were raised on commercial wood shavings containing ppm pentachlorophenol and on control litter consisting of corncob chips initial analysis of the woodshaving litter showed the presence of hepta octa and nonachlorinated diphenyl ethers octa and nonachlorinated phenoxyphenols and hepta and octachlorinated dibenzodioxins analysis of liver fat and muscle tissue T3 nine weeks indicated the assimilation of these EDC with pentachlorophenol being present in the highest concentration chlorinated diphenyl ethers were detectable only in fat while octa and nonachlorinated phenoxyphenols were found in all three tissues examined while CL and fat contained hepta and octachlorinated dibenzodioxins no hexachlorinated congener was detected nor were significant amounts of dioxin found in muscle tissue although gross pathological examination of the birds did not indicate CA a mixed type of hepatic enzyme induction was observed in those birds raised on wood shavings | MEDAL |
cardiac ultrasound plays a pivotal role in assessing pulmonary artery pressures estimation of RA atrial pressure can be derived from the dimensions and respiratory variation of the VPI vena cava and doppler modalities provide an accurate and comprehensive evaluation of RA ventricular and PAPs peak pulmonary i.a. pressure can be calculated from continuous PWD sampling of the tricuspid regurgitant jet while pulsed wave doppler sampling of the pulmonary regurgitant jet allows DUE of mean and diastolic PAPs in patients with tricuspid regurgitation that is either absent or not adequately detectable by doppler method doppler right VVI outflow tract investigation can be helpful recent data indicate that analysis of RA VF using myocardial doppler echocardiography may also provide new insights for the noninvasive estimation of pulmonary artery pressures in particular RA VVI isovolumic EC50 time measured by myocardial doppler echocardiography at the tricuspid annulus may provide an alternative method for estimating pulmonary artery pressure especially in patients with TR not detectable or spectral doppler not properly interpretable | MEDAL |

many insect species use multicomponent sex pheromones to discriminate among potential mating partners in moths pheromone blends tend to be dominated by one or two L1 components but behavioral responses are frequently optimized by the inclusion of less abundant minor components an increasing number of studies have shown that female insects use these chemicals to convey their mating availability to males who can assess the maturity of females and thus decide when to mate however little is known about the biological mechanisms that enable males to assess female reproductive status in this T0 we found that females of helicoverpa armigera avoid nonoptimal mating by inhibiting males with pheromone antagonist cishexadecenol zoh we also show that this antagonistmediated optimization of mating time ensures maximum fecundity to further investigate molecular aspects of this phenomenon we used the crisprcas system to knock out odorant receptor or the only pheromone receptor tuned to zoh in mutant males electrophysiological and behavioral responses to zoh were abolished inability to detect zoh prompted the males to mate with immature females which resulted in significantly reduced viability of eggs in conclusion our T0 demonstrates that the sensitivity of or to zoh regulates optimal mating time and thus ensures maximum fecundity these results may suggest novel strategies to disrupt pest insect mating | MEDAL |

activitydependent alteration in synaptic strength is a fundamental property of the vertebrate CNS system and is thought to underlie learning and SM the most extensively studied MM of activitydependent synaptic plasticity is LT potentiation ltp of glutamateresponsive glutamatergic synapses a widespread phenomenon involving multiple mechanisms the best characterized form of ltp occurs in the ca region of the hippocampus in which ltp is initiated by transient activation of nmda nmethyldaspartate receptors and is expressed as a persistent increase in synaptic transmission through ampa alphaaminohydroxymethylisoxazolepropionate receptors this increase is due at least in part to a postsynaptic modification of ampareceptor function this modification could be caused by an increase in the number of receptors their open probability their kinetics or their singlechannel conductance here we show that the induction of ltp in the ca region of the hippocampus is often associated with an increase in singlechannel conductance of ampa receptors this shows that elementary channel properties can be rapidly modified by synaptic activity and provides an insight into one molecular mechanism by which glutamatergic synapses can alter their strength | MEDAL |

canine tracheal smooth muscle strips were mounted horizontally in a tissue bath between a force transducer and a motordriven movable steel rod which was used to change ML muscle length and force were continuously measured during stretch and simultaneously plotted on an xy recorder AS force during stretch was investigated as follows an initial length was set with the muscle relaxed where it was contracted isometrically with acetylcholine T3 active force reached a Css muscle length was decreased until the total tension was equal to zero the muscle was then stretched slowly to obtain a continuous lengthforce curve results show that force during stretch increases as the length at which the initial isometric contraction is elicited is decreased a possible interpretation is that during tonic muscle contraction the contractile element is able to shorten very slowly relative to the rate at which the muscle was retracted thus the CE length established during ISO contraction would affect the muscle force obtained during subsequent stretch of the muscle | MEDAL |

along the perinatal period in mammals cortisol c plays a pivotal role in the final intrauterine fetal maturation and in the early neonatal adaptation because of the scarce knowledge about canine perinatology the present study was aimed to assess the c concentrations in amniotic and allantoic fluids collected without invasiveness from smallsized purebred newborn puppies born by ECS at term of pregnancy possible correlations between fetal fluid c concentrations and maternal parity litter size birth weight apgar score were evaluated in addition the possible effect of fetal fluid c concentrations on P0 survival at hours of age and the effect of the litter or the newborn gender on fetal fluid c concentrations were also assessed the results obtained from born alive normalweight puppies without gross physical malformation showed that c concentration was higher in allantoic than in amniotic fluid p even if a strong positive rho between the two fluids c concentration was found p r neither amniotic nor allantoic c concentrations were correlated to maternal parity LS birth weight and apgar score interestingly higher amniotic p but not allantoic c concentrations were found in puppies not surviving at hours after birth therefore it could be suggested that this parameter may be useful for the recognition at birth of puppies needing special surveillance during the D1 of age a significant p effect of the litter in both amniotic and allantoic c concentrations was found in conclusion the present results showed that in smallsized purebred puppies born at term by ECS the exact fetal maternal or placental source contributing to fetal fluid c concentrations remains to be clarified from a clinical perspective however the evaluation of amniotic c concentration at birth seems useful for the detection of puppies that need special surveillance during the first hours of age and should be coupled to the early P0 evaluation by apgar score however the small total number of newborns and especially of the dead puppies enrolled in the present study suggests that further morefocused investigations on a C1 number of subjects are needed before the method could be considered for application in the clinical practices | MEDAL |
