Glutamate excitotoxicity contributes to neurodegeneration during cerebral ischemia. Recent studies in the protective effect of glutamate against ischemia and hypoxia have shown the need for questioning the role of glutamate in energy metabolism during ischemia. Current study investigates the effect of glutamate on energy substrate metabolites such as alpha-ketoglutarate, lactate, and pyruvate release during control, oxygen-glucose deprivation (OGD), and reoxygenation (REO) conditions.

The effects of 0.5 and 2 mM glutamate on spontaneous alpha-ketoglutarate, lactate, and pyruvate release were tested in vitro, on acute rat cortical slices. Alpha-ketoglutarate, lactate, and pyruvate levels were determined by HPLC with UV detector.

We observed that glutamate added into medium significantly increased alpha-ketogluarate release under control conditions. Although OGD and REO also had a glutamate-like effect, only REO-induced rise further enhanced by glutamate. In contrast to alpha-ketoglutarate, both OGD and Rsorders, including cerebral ischemia.1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) can damage dopaminergic neurons in the substantia nigra in many mammals with biochemical and cellular changes that are relatively similar to those observed in Parkinson's disease. Our study examined whether MPTP-treated echolocation bats can cause changes in bat echolocation system. By considering ultrasound spectrums, auditory brainstem-evoked potentials and flight trajectories of normal bats, we observed that the vocal, auditory, orientation and movement functions of MPTP-treated bats were significantly impaired, and they exhibited various symptoms resembling those in patients with Parkinson's disease. Our immunohistochemistry and western blot analyses further indicated that expression of vocal-related FOXP2 in the superior colliculus, auditory-related otoferlin in the inferior colliculus, dopamine synthesis-related aromatic l-amino acid decarboxylase in the substantia nigra and dopamine receptor in the striatum was significantly decreased. Furthermore, protein expression related to inflammation, oxidative stress and apoptosis in the substantia nigra was significantly increased in MPTP-treated bats. These results indicate that inflammation, oxidative stress and apoptosis may be instrumental in dopaminergic neurodegeneration in the substantia nigra. The vocal, auditory and orientation and movement dysfunctions of MPTP-treated bats are relatively consistent with symptoms of Parkinson's disease.Isoflurane is an inhaled anesthetic, though its actions at the cellular level remain controversial. By using acute spinal cord slices from adult rats and the whole-cell recording technique, we found that aqueous isoflurane at the minimum alveolar concentration decreased postsynaptic neural excitability and enhanced membrane conductance, while suppressing glutamate release from presynaptic afferent onto substantia gelatinosa (lamina II) neurons in the dorsal horn. The data demonstrate that isoflurane modulates synaptic transmission from peripheral to the spinal cord via both pre- and postsynaptic effects and these actions may underlie its spinal anesthesia.
Fibromyalgia (FM) is a complex syndrome of uncertain etiology, characterized by the presence of widespread pain. Both nitric oxide and enkephalinases modulate pain perception.

The aim of this study was to evaluate the relationships among serum nitric oxide levels, oxytocinase activity and enkephalin-degrading aminopeptidase (EDA) activity with pain-related clinical manifestations in women with fibromyalgia.

We performed an observational case study in a population of fifty-eight women diagnosed with fibromyalgia. Serum nitric oxide levels were analyzed by an ozone chemiluminescence-based assay. Both serum oxytocinase and EDA activities were fluorometrically determined. Pain threshold and pain magnitude were evaluated using the Pain Matcher. The pressure pain thresholds were measured using a digital pressure algometer. We used a Visual Analog Scale, the Central Sensitization Inventory, the Revised Fibromyalgia Impact Questionnaire, and the Beck Anxiety Inventory to assess the global level of pain, the symtric oxide levels and in oxytocinase and EDA activities in patients with fibromyalgia.
Our data have shown significant relationships of serum nitric oxide levels and oxytocinase and EDA activities with some body pressure pain thresholds, the daily activity level, and the global intensity of pain in women with fibromyalgia. These results suggest that pain, which is the main symptom of this syndrome, may be related to alterations in nitric oxide levels and in oxytocinase and EDA activities in patients with fibromyalgia.
A permissive drinking culture is one reason for the high level of alcohol consumption among Korean men. Despite shared experiences of the Korean drinking culture that often encourages social drinking, Korean American and Korean male workers may differ in their drinking behavior. This study examines the predictors of controlled drinking behavior and between these two groups.

The purpose of this study was to examine and compare the predictors of controlled drinking behavior between Korean American and Korean male workers.

A total of 282 male participants (141 Korean Americans and 141 Koreans) who engaged in social drinking were surveyed. Ajzen's theory of planned behavior was used to examine the predictors of controlled drinking behavior. Structural equation modeling was employed to test the theoretical model for each group, followed by multiple group analyses.

The majority of participants were college-educated and white-collar workers. Korean American workers had fewer heavy episodic drinking days in tth a strict drinking environment needs to be considered to improve controlled drinking behaviors.
There are multiple issues that arise when researchers focus on and only report "statistical significance" of study findings. An important element that is often not included in reports is a discussion of clinical relevance.

The authors address issues related to significance, the use of effect sizes, confidence or credible intervals, and the inclusion of clinical relevance in reports of research findings.

Measures of magnitude, precision, and relevance such as effect sizes, confidence intervals (CIs), and clinically relevant effects are described in detail. In addition, recommendations for reporting and evaluating effect sizes and CIs are included. Example scenarios are presented to illustrate the interplay of statistical significance and clinical relevance.

There are several issues that may arise when significance is the focus of clinical research reporting. BIIB129 One issue is the lack of attention to nonsignificant findings in published works although findings show clinical relevance. Another issue is that significance is interpreted as clinical relevance.
