OBJECTIVE We examine remission rate probabilities, recovery rates, and residual symptoms across 36 weeks in the Treatment for Adolescents with Depression Study (TADS). METHOD The TADS, a multisite clinical trial, randomized 439 adolescents with major depressive disorder to 12 weeks of treatment with fluoxetine, cognitive-behavioral therapy, their combination, or pill placebo. The pill placebo...

Previously, studying the development, especially of corticospinal neurons, it was concluded that the main compensatory mechanism after unilateral brain injury in rat at the neonatal stage was due in part to non-lesioned ipsilateral corticospinal neurons that escaped selection by axonal elimination or neuronal apoptosis. However, previous results suggesting compensatory mechanism in neonate brai...

Contrary to previous studies, we found that Xenopus laevis tadpoles raised in normoxic water without access to air can routinely complete metamorphosis with lungs that are either severely stunted and uninflated or absent altogether. This is the first demonstration that lung development in a tetrapod can be inhibited by environmental factors and that a tetrapod that relies significantly on lung ...

Truncated escape responses characteristic of the zebrafish shocked mutant result from a defective glial glycine transporter (GlyT1). In homozygous GlyT1 mutants, irrigating brain ventricles with glycine-free solution rescues normal swimming. Conversely, elevating brain glycine levels restores motility defects. These experiments are consistent with previous studies that demonstrate regulation of...

Intermittent, chronically delivered electrical stimulation of the vagus nerve (VNS) is an FDA-approved procedure for the treatment of refractory complex/partial epilepsy in humans. Stimulation of the vagus has also been shown to enhance memory storage processes in laboratory rats and human subjects. Recent evidence suggests that some of these effects of VNS may be due to the activation of neuro...

Introduction: The aim of this study was to assess the effect of Ca2+/calmodulin-dependent kinase IIα (CaMKIIα) inhibitor (KN-93) injection into the locus coeruleus (LC) on the modulation of withdrawal signs. We also sought to study the effect of chronic morphine administration on CaMKIIα activity in the rat LC. Methods: The research was based on behavioral and molecular studies. In the behav...

objective: the nucleus accumbens (nac) receive histaminergic neurons from tuberomammillary nuclei. there are reports indicating that central histamine systems are involved in many physiological behavioral processes, including anxiety. the aim of the present study was to assess whether the histaminergic system of the nac is involved in anxiety-related behaviors. methods:   rats   were   anesthet...

The repair of peripheral nerve injuries is still one of the most challenging tasks and concerns in neurosurgery. Effect of methylprednisolone-laden hydrogel loaded into a chitosan conduit on the functional recovery of peripheral nerve using a rat sciatic nerve regeneration model was assessed. A 10-mm sciatic nerve defect was bridged using a chitosan conduit (CHIT/CGP-Hydrogel) filled with CGP-h...

Following unilateral striatal dopamine depletion, the hemiparkinsonian rat exhibits rotational behavior in response to amphetamine and apomorphine. The rotational behaviors induced by these drugs are thought to reflect an asymmetry in presynaptic striatal dopamine release and an asymmetry in postsynaptic striatal dopamine receptor function, respectively. Grafts of adrenal medulla cells in the l...
