Most third- and fourth-generation cephalosporins, such as cefotaxime, cefmenoxime, cefepime, and cefpirome, contain an aminothiazoyl ring at the C-7 position. Drug impurity, which may be produced either during synthesis or upon degradation, can induce adverse effects. Various reports have indicated that neurotoxicity is a side effect of cephalosporin. In this study, we developed methods for assessing the free-swimming activities and behaviors in zebrafish larvae in response to continuous darkness and stimulation of light-to-dark photoperiod transition by chemical treatments...

Stressful life events are thought to be triggering factors of numerous neuropsychiatric disorders, including anxiety and depression. However, the interactions between chronic unpredictable mild stress (CUMS) and immune stimulation have not been thoroughly investigated. In the present study, we evaluated the effects of lipopolysaccharide (LPS) challenge at different time points on CUMS-induced anxiety- and depression-like behaviors. At 1 day before, 18 or 35 days following the initial of CUMS, mice were intraperitoneally given a single LPS (0...

Tenascin-C (TNC), a matricellular protein, is upregulated in brain parenchyma after experimental subarachnoid hemorrhage (SAH). Recent studies emphasize that early brain injury (EBI) should be overcome to improve post-SAH outcomes. The aim of this study was to investigate effects of TNC knockout (TNKO) on neuronal apoptosis and neuroinflammation, both of which are important constituents of EBI after SAH. C57BL/6 wild-type (WT) mice or TNKO mice underwent sham or filament perforation SAH modeling. Twenty-five WT mice and 25 TNKO mice were randomly divided into sham+WT (n = 10), sham+TNKO (n = 8), SAH+WT (n = 15), and SAH+TNKO (n = 17) groups...

The enzyme steroid 5α-reductase 2 (5αR2) catalyzes the conversion of testosterone into the potent androgen 5α-dihydrotestosterone. Previous investigations showed that 5αR2 is expressed in key brain areas for emotional and socio-affective reactivity, yet the role of this enzyme in behavioral regulation remains mostly unknown. Here, we profiled the behavioral characteristics of 5αR2 heterozygous (HZ) and knockout (KO) mice, as compared with their wild-type (WT) littermates. While male 5αR2 KO mice displayed no overt alterations in motoric, sensory, information-processing and anxiety-related behaviors, they exhibited deficits in neurobehavioral correlates of dominance (including aggression against intruders, mating, and tube dominance) as well as novelty-seeking and risk-taking responses...

The objective of this study was to evaluate whether prenatal exposures to organophosphate (OP) pesticides from maternal agricultural use are associated with neonatal neurobehavioral effects. A pilot study conducted in three provinces in Thailand measured maternal urinary metabolites of OP pesticides in pregnant women at 7 months gestation and at birth. Within 3 days of birth, 82 newborns underwent neurobehavioral testing using the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Comparison of the NBAS test results with maternal OP metabolite levels found the neonates NBAS Habituation cluster score increased with maternal dimethylphosphate (DMP) levels (p = 0...

Maternal infection during pregnancy increases the risk of neurobehavioral problems in offspring. Evidence from rodent models indicates that the maternal immune response to infection can alter fetal brain development, particularly in the hippocampus. However, information on the effects of maternal viral infection on fetal brain development in gyrencephalic species is limited. Thus, the objective of this study was to assess several effects of maternal viral infection in the last one-third of gestation on hippocampal gene expression and development in fetal piglets...

BACKGROUND: Depression and/or anxiety during pregnancy have been associated with impaired fetal growth and neurodevelopmental. Because placental imprinted genes play a central role in fetal development and respond to environmental stressors, we hypothesized that imprinted gene expression would be affected by prenatal depression and anxiety. METHODS: Placental gene expression was compared between mothers with prenatal depression and/or anxiety/obsessive compulsive disorder/panic and control mothers without psychiatric history (n=458) in the Rhode Island Child Health Study...

BACKGROUND: Kabuki syndrome (KS) is a disorder characterized by multiple congenital anomalies affecting development and function of multiple systems. Over the years, researchers have attempted to characterize the neurobehavioral phenotype of KS in cohorts of patients enrolled on the basis of clinical assessment. The availability of molecular testing now allows for recruitment of patients with confirmed KS due to KMT2D and KDM6A. METHODS: The aims of the present study were to investigate the neuropsychological and behavioral profiles of individuals with molecularly confirmed diagnosis of KS, and determine the extent of heterogeneity occurring in these profiles between individuals with clinical diagnosis of KS with and without mutations in KMT2D...

When people hear unexpected perturbations in auditory feedback, they produce rapid compensatory adjustments of their vocal behavior. Recent evidence has shown enhanced vocal compensations and cortical event-related potentials (ERPs) in response to attended pitch feedback perturbations, suggesting that this reflex-like behavior is influenced by selective attention. Less is known, however, about auditory-motor integration for voice control during divided attention. The present cross-modal study investigated the behavioral and ERP correlates of auditory feedback control of vocal pitch production during divided attention...

Preterm infants are hospitalized in the Neonatal Intensive Care Unit (NICU) and are precociously separated from their mothers. Although developmental care interventions are meant to facilitate mother-infant bonding, physical contact is not always possible. Maternal voice exposure has been proposed as a way to foster maternal closeness and support postnatal bonding. Here we present a systematic review on maternal voice effects on preterm infants' development. Literature search occurred on 4 databases (PubMed, Scopus, Web of Science and CINAHL)...

Explosive blast-induced mild traumatic brain injury (mTBI), a "signature wound" of recent military conflicts, commonly affects service members. While past blast injury studies have provided insights into TBI with moderate- to high-intensity explosions, the impact of primary low-intensity blast (LIB)-mediated pathobiology on neurological deficits requires further investigation. Our prior considerations of blast physics predicted ultrastructural injuries at nanoscale levels. Here, we provide quantitative data using a primary LIB injury murine model exposed to open field detonation of 350 grams of high-energy explosive C4...

Perfluorooctanesulfonate (PFOS)-containing compounds are widely used in all aspects of industrial and consumer products. Recent studies indicated that PFOS is ubiquitous in environments and is considered to be a new type of persistent organic pollutant (POP). This has raised concerns regarding its adverse effects on human health. The nervous system is regarded as a sensitive target of environmental contaminants, including PFOS. Previous findings showed that PFOS can induce neurobehavioral deficits. However, the molecular mechanism underlying PFOS neurotoxicity remains obscure...

The present study evaluated the effects of s-nitrosoglutathione (GSNO), a nitrosothiol and sustained NO releaser, on experimental model of sporadic Alzheimer`s disease (sAD) in rats. Levels of Aβ40, Aβ42 and BDNF were assessed in brain hippocampal homogenates for correlative purposes. Intracerebroventricular-Streptozotocin (icv-STZ) induced increased escape latencies (acquisition) and reduced time in target quadrant (probe trial) in Morris Water Maze (MWM) test at 3 months post icv-STZ administration. These behavioural changes were associated with increased Aβ depositions and lowered BDNF levels in brain hippocampal homogenates...

Groundwater used for drinking has been contaminated with naturally occurring inorganic arsenic and other metals, and metal-contaminated drinking water is the biggest threat to public health in Bangladesh. Toxic metals present in the drinking water have a strong relationship with chronic diseases in humans. Antimony (Sb), a naturally occurring metal, has been reported to be present in the drinking water along with other heavy metals in Bangladesh. Although Sb is present in the environment, very little attention has been given to the toxic effects of Sb...
