Immunochromatographic sensors (ICSs) are inexpensive, simple, portable, and robust, thus making ICSs commonplace in clinical diagnoses, food testing, and environmental monitoring. However, commonly used gold nanoparticles (AuNPs) ICSs have low sensitivity. Therefore, we developed highly sensitive surface enhanced Raman scattering (SERS) ICSs. To enhance the sensitivity of SERS ICSs, rough surfa...

OBJECTIVE To review the efficacy and safety of inhaled corticosteroids (ICSs) when used to reduce daily oral corticosteroid (OCS) requirements in patients with severe persistent asthma and periodic requirements in patients with acute asthma exacerbations. DATA SOURCES Clinical studies of the OCS-sparing effects of ICSs were located by searching MEDLINE databases from 1966 onward using the ter...

The neurotransmitter dopamine is heavily implicated in intracranial self-stimulation (ICSS). Many drugs of abuse that affect ICSS behavior target the dopaminergic system, and optogenetic activation of dopamine neurons is sufficient to support self-stimulation. However, the patterns of phasic dopamine release during ICSS remain unclear. Early ICSS studies using fast-scan cyclic voltammetry (FSCV...

M e t h o d s Data sources: Cochrane Airways Group Asthma trials register, Cochrane Central Register of Controlled Trials, references of relevant articles, pharmaceutical companies manufacturing ALs and ICSs, and abstracts of the American Thoracic Society and European Respiratory Society Meetings (1998 to 2003). Study selection and assessment: Randomized controlled trials (RCTs) comparing ALs p...

Intracranial self-stimulation (ICSS) activates the neural pathways that mediate reward, including dopaminergic terminal areas such as the nucleus accumbens (NAc). However, a direct role of dopamine in ICSS-mediated reward has been questioned. Here, simultaneous voltammetric and electrophysiological recordings from the same electrode reveal that, at certain sites, the onset of anticipatory dopam...

BACKGROUND Intraplantar administration of complete Freund's adjuvant (CFA) and formalin are two noxious stimuli commonly used to produce sustained pain-related behaviors in rodents for research on neurobiology and treatment of pain. One clinically relevant manifestation of pain is depression of behavior and mood. This study compared effects of intraplantar CFA and formalin on depression of posi...

BACKGROUND Despite the presence of existing guidelines, underuse of inhaled corticosteroids (ICSs) still exists among patients with persistent asthma in the United States. Inappropriate utilization of asthma medications has been attributed as one of the reasons for the significant economic burden due to asthma. OBJECTIVES To determine the demographic factors predicting patient-reported use of...

PURPOSE OF REVIEW The purpose of this review is to compare and contrast the newer inhaled corticosteroid (ICS) ciclesonide with older ICSs in terms of pharmacodynamic and pharmacokinetic properties and how these affect comparative efficacy. In addition, clinical dosing strategies for ICSs including as-needed use will be explored. RECENT FINDINGS Ciclesonide has demonstrated similar efficacy t...

BACKGROUND Prescription opioid abuse is a significant concern in treating chronic pain, yet few studies examine how neuropathic pain alters the abuse liability of commonly abused prescription opioids. METHODS Normal and spinal nerve ligated (SNL) rats were implanted with electrodes into the left ventral tegmental area (VTA). Rats were trained to lever press for intracranial electrical stimula...

The neural basis of positive reinforcement is often studied in the laboratory using intracranial self-stimulation (ICSS), a simple behavioral model in which subjects perform an action in order to obtain exogenous stimulation of a specific brain area. Recently we showed that activation of ventral tegmental area (VTA) dopamine neurons supports ICSS behavior, consistent with proposed roles of this...
