Delirium is a frequent outcome for aged and demented patients that suffer a systemic inflammatory insult. Animal models that reconstruct these etiological processes have potential to provide a better understanding of the pathophysiology of delirium. Therefore, we systematically reviewed animal studies in which systemic inflammation was superimposed on aged or diseased animal models. In total, 77 studies were identified. Aged animals were challenged with a bacterial endotoxin in 29 studies, 25 studies superimposed surgery on aged animals, and in 6 studies a bacterial infection, Escherichia coli (E...

BACKGROUND: Ethanol exposure during different phases of life may increase the risk of infections and cause alterations in the central nervous system. The present study investigated the effects of binge-like ethanol exposure in adolescent rats on the febrile response that was induced by lipopolysaccharide (LPS) and interleukin-1β (IL-1β). METHODS: Male rats were exposed to ethanol from postnatal day 25 to 38 in a binge-like pattern. Fever was induced by LPS (5 and 50 μg/kg, intraperitoneally) and evaluated on postnatal day 51 and 63, or by IL-β (3 ng) and evaluated on postnatal day 51...

MicroRNAs (miRNAs) are short, non-coding RNAs involved in the regulation of several processes associated with inflammatory diseases and infection. Bacterial infection modulates miRNA expression to subvert any innate immune response. In this study, we analyzed bacterial modulation of miRNAs in bone-marrow-derived macrophages (BMMs), in which activity was induced by infection with Porphyromonas gingivalis (Pg) through a microarray analysis. Several miRNA expressions were modulated 3 hours post infection (at a MOI of 25)...

The most commonly used techniques to measure vitamin D are automated immunoassays which are known to be affected by interferences, especially from immunoglobulins present in the patient's serum. We present a case of a patient with myeloma in whom interference with the vitamin D assay was identified. An eighty-three year old female, known to have IgG myeloma was found to have a high concentration of 25-OH vitamin D on a routine test without any signs of vitamin D toxicity. She was not taking vitamin D supplements or any other multivitamin preparation and had minimal sun exposure...

The current study was designed to investigate the therapeutic potential of berberine on monosodium urate (MSU) crystal stimulated RAW 264.7 macrophages and in MSU crystal induced rats. Our results indicate that berberine (25, 50 and 75μM) suppressed the levels of pro-inflammatory cytokines (interleukin-1beta (IL-1β) and tumor necrosis factor alpha (TNFα)) and intracellular reactive oxygen species in MSU crystal stimulated RAW 264.7 macrophages. The mRNA expression levels of IL-1β, caspase 1, nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3 (NLRP3), thioredoxin interacting protein (TXNIP) and kelch-like ECH-associated protein 1 (Keap1) were found downregulated with the upregulation of nuclear factor erythroid-2-related factor 2 (Nrf2) transcription factor and its associated anti-oxidant enzymes: Heme oxygenase I (HO-1), superoxide dismutase (SOD1), glutathione peroxidase (GPx), NADPH quinone oxidoreductase-1 (NQO1) and catalase (CAT) in MSU crystal stimulated RAW 264...

The present study aimed to show that pro-inflammatory cytokines [tumor necrosis factor (TNF)-α, interferon (IFN)-γ, and interleukin (IL)-1β] synergistically induce the production of nitric oxide (NO) production in mouse mesangial cells, which play an important role in inflammatory glomerular injury. We also found that co-treatment with cytokines at low doses (TNF-α; 5 ng/ml, IFN-γ; 5 ng/ml, and IL-1β; 1.25 U/ml) synergistically induced NO production, whereas treatment with each cytokine alone did not increase NO production at doses up to 100 ng/ml or 50 U/ml...

Thus far, phosphodiesterase-4 (PDE4) inhibitors have not been approved for application in Alzheimer's disease (AD) in a clinical setting due to severe side effects, such as nausea and vomiting. In this study, we investigated the effect of FFPM, a novel PDE4 inhibitor, on learning and memory abilities, as well as the underlying mechanism in the APP/PS1 mouse model of AD. Pharmacokinetic studies have revealed that FFPM efficiently permeates into the brain, and reached peak values in plasma 2 h after orally dosing...

BACKGROUND/PURPOSE: The purpose of the study was to determine if testicular delivery during microsurgical subinguinal varicocelectomy (MSV) reduces varicocele recurrence rates in pediatric patients. Testicular delivery during MSV enables ligation of the gubernacular veins, which is thought to reduce the likelihood of varicocele recurrence. However, recent studies have suggested that testicular delivery during MSV does not offer any beneficial effect and, therefore, may be optional or unnecessary...

Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease with pruritus and high prevalence. Indeed, 15-30 % of children and 2-10 % of adults from industrialized countries are affected. Acute AD lesions are characterized by epidermal hyperplasia associated with a dominant Th2/Th17 immune response and dermal inflammatory infiltrates. Moreover, the expression of alarmins such as TSLP, IL-33, and IL-25 is upregulated in acute AD lesions. Topical application of vitamin D3 or of its low-calcemic analog MC903 induces changes in skin morphology and inflammation resembling immune perturbations observed in acute lesions of patients with AD...
