Physiological Role of TNF in Mucosal Immunology : Regulation of Macrophage/Dendritic Cell Function

Intestinal mononuclear phagocytes, comprising macrophages (Mφs) and dendritic cells (DCs), play important roles in the generation and the regulation of immune responses to intestinal antigens, and alterations in the development and/or the function of these cells are thought to contribute to the pathogenesis of inflammatory bowel disease. In this review, we discuss the role of tumor necrosis factor

Optimization of sound absorbing ceilings

The typical acoustical treatment in ordinary rooms such as classrooms, offices, conference rooms etc is an absorbing suspended ceiling. Due to the non-uniform distribution of the absorbing material the sound field at steady-state and during sound decay is far from the ideal conditions assumed in the diffuse field theory. Especially during the sound decay, the degeneration of the sound field emphas

Temporal patterns of interstitial pyruvate and amino acids after subarachnoid haemorrhage are related to the level of consciousness--a clinical microdialysis study

BACKGROUND: Temporal patterns of brain interstitial amino acids after subarachnoid haemorrhage (SAH) were studied in relation to energy metabolite levels and to the severity of the initial global ischaemia as reflected by the level of consciousness at admission.METHOD: Intracerebral microdialysis was used to measure brain interstitial amino acids and the energy metabolites glucose, lactate, and py

Relationship between intracranial hemodynamics and microdialysis markers of energy metabolism and glutamate-glutamine turnover in patients with subarachnoid hemorrhage. Clinical article

OBJECT: The aim of this study was to explore the relationship between hemodynamics (intracranial and systemic) and brain tissue energy metabolism, and between hemodynamics and glutamate (Glt)-glutamine (Gln) cycle activity.METHODS: Brain interstitial levels of lactate, pyruvate, Glt, and Gln were prospectively monitored in the neurointensive care unit for more than 3600 hours using intracerebral m

Lactic acid bacteria colonization and clinical outcome after probiotic supplementation in conventionally treated bacterial vaginosis and vulvovaginal candidiasis

This randomized double-blind placebo controlled study assessed the vaginal colonization of lactic acid bacteria and clinical outcome. Vaginal capsules containing L gasseri LN40, Lactobacillus fermentum LN99, L. casei subsp. rhamnosus LN113 and P. acidilactici LN23, or placebos were administered for five days to 95 women after conventional treatment of bacterial vaginosis and/or vulvovaginal candid

The effects of PBN (phenyl-butyl-nitrone) on GLT-1 levels and on the extracellular levels of amino acids and energy metabolites in a model of iron-induced posttraumatic epilepsy

This study investigates astrocytic glutamate uptake in the iron-induced animal model of posttraumatic epilepsy. Since formation of free radicals may be involved in epileptogenesis after brain trauma and hemorrhage the effects of the nitrone radical scavenger alpha-phenyl-tert-N-butyl nitrone (PBN) were also studied. Animals received an intracortical iron injection, or were sham-operated. They were

Decreased cortical levels of astrocytic glutamate transport protein GLT-1 in a rat model of posttraumatic epilepsy

The extracellular homeostasis of glutamate in the brain is maintained by the efficient uptake into astroglial cells. The high extracellular glutamate levels seen during seizures are therefore probably a result of both an increased synaptic release and a deranged glutamate uptake. In this study we used immuno-blotting technique to measure the cortical levels of the astrocytic glutamate transport pr

Microdialysis patterns in subarachnoid hemorrhage patients with focus on ischemic events and brain interstitial glutamine levels

BACKGROUND: This observational microdialysis (MD) study of 33 subarachnoid hemorrhage patients explores brain interstitial levels of glutamine, glutamate, lactate and pyruvate, and their relationship to clinical status and clinical course at the neurointensive care unit.METHODS: The focus was on ischemic events, defined by clinical criteria or by radiology, and the significance of brain interstiti

Studies on the interaction between hyaluronan and a rat colon cancer cell line

Binding studies with 125I-Tyr labelled hyaluronan (HA) on a cultured rat colon cancer cell line were performed to characterize the association of HA to tumour cells in vitro. Results show a specific and saturable binding (Kd=1.36 nM) which indicates the presence of an HA binding receptor on the tumour cells. There is a specific constant increase of cell-associated HA over time, which indicates tha

Single-ion conducting polymer electrolytes with alternating ionic mesogen-like moieties interconnected by poly(ethylene oxide) segments

Solid single-Li+-ion conducting polymer electrolytes are currently explored for safe high-temperature lithium batteries. In the present work we have prepared and studied materials based on alternating mesogen-like naphthalene sulfonate units interconnected by flexible poly(ethylene oxide) (PEO) segments in order to induce microphase separation and physical crosslinking. These segmented polymers we
