Introduction: Noradrenergic cells in LC participate in the process of cortical activation and behavioral arousal. The evidence suggests that locus ceoruleus (LC) plays an important role in the sleep-wake cycle. The aim of this study was stereological estimation of cavity caused by lesion and assessment of sleep stages after bilateral lesion of the LC. Materials and Methods: Male Wistar rats we...

--Coupled LC oscillators are known to provide good performance in terms of phase noise, signal amplitude, power consumption, and quadrature output signals. However, IQ amplitude and phase mismatches in these oscillators can be quite large due to the serious mismatch problem of large area inductors and varactors. A simple design modification of the coupled LC oscillators shows a significant impr...

Introduction: It has been shown that orexin peptides have a role in opioid withdrawal behaviors. Orexin-expressing neurons that are present in the hypothalamic nuclei send dense projections to the Locus Coeruleus (LC). Withdrawal syndrome is temporally associated with hyperactivity of LC neurons. However, LC neurons do not show withdrawalinduced hyperactivity in the brain slices from morphin...

In this study, the effect of reversible inactivation of locus ceruleus (LC) on naloxone- induced withdrawal syndrome in paragigantocellular (PGi) neurons in morphine- dependent rats was investigated. For inactivation of LC, 1 µl of lidocaine (2%) was used and for induction of withdrawal syndrome, naloxone hydrochloride (2 mg/kg) was injected systemically. The results showed that in dependent gr...

Sex differences have been identified in various biological processes, including hypertension. The mineralocorticoid signaling pathway is an important contributor to early arterial hypertension, however its sex-specific expression has been scarcely studied, particularly with respect to the kidney. Basal systolic blood pressure (SBP) and heart rate (HR) were measured in adult male and female mice...

To date, the proteomic profiling of Müller cells, the dominant macroglia of the retina, has been hampered because of the absence of suitable enrichment methods. We established a novel protocol to isolate native, intact Müller cells from adult murine retinae at excellent purity which retain in situ morphology and are well suited for proteomic analyses. Two different strategies of sample preparat...

Although the favourable characteristics of escitalopram as being the most selective serotonin reuptake inhibitor and having an increased therapeutic efficacy via binding on an additional allosteric binding site of the serotonin transporter, its dosing regimen has not yet been optimized for its use in dogs. This study aimed to estimate the optimal dosing frequency and the required dose for achie...

introduction: pain as a complex process in the cns has been extensively studied by many researchers. it has been found that pain is controlled by certain pathways in the cns, one of most important of which is the descending noradrenergic system. the pathway begins with locus coeruleus (lc) nucleus and ends in the spinal cord. in this study, formalin test was used as a chemical and tonic pain te...

background: bifenthrin and acorus calamus linn extract were evaluated against dengue vectors in the laboratory. methods: both bifenthrin and acorus calamus linn crude hexane extract were bioassayed against the adults and larval stages of dengue vectors aedes aegypti l. and aedes albopictus(skuse) in the laboratory. results: the a. calamus crude hexane extract exhibited a larvicidal activity aga...
