OBJECTIVE: Inflammasomes are multiprotein complexes, and their activation has been associated with cardiovascular disease. Inflammasome activation leads to secretion of caspase-1 by innate immune cells, resulting in the activation of interleukin-1β. Recently, a potent and selective inhibitor of the NLRP3 inflammasome, MCC950, was described. In this study, we investigated the effect of MCC950 on atherosclerotic lesion development in apoE(-/-) mice. APPROACH AND RESULTS: First, we determined the efficacy of MCC950 in vitro...

BACKGROUND: Selenium is well documented to inhibit cancer at higher doses; however, the mechanism behind this inhibition varies widely depending on the cell type and selenium species. Previously, we have demonstrated that Bacillus licheniformis JS2 derived biogenic selenium nanoparticles (SeNPs) induce non-apoptotic cell death in prostate adenocarcinoma cell line, PC-3, at a minimal concentration of 2 µg Se/ml, without causing toxicity to the primary cells. However, the mechanism behind its anticancer activity was elusive...

The anti-diabetic metformin has been demonstrated to be effective in suppression of tumor progression via multiple mechanisms, in which angiogenic inhibition is involved. Hypoxia is a common feather of malignant tumor and promotes angiogenesis via induction of pro-angiogenic factors. However, the effect of metformin on tumor hypoxia and the association with angiogenic inhibition are still unclear. In the current study, we investigated the effects of metformin on both tumor blood perfusion and hypoxia-induced excessive angiogenesis...

Acute necrotizing pancreatitis (ANP) is a common severe critical illness with a high mortality rate. Resveratrol, a polyphenol compound derived from various plants such as grape skin, peanut, berry and veratrum, exhibits multiple biological activities, especially potent anti‑inflammatory activity, but its effect on ANP has not yet been fully elucidated. The present study aimed to investigate the effects of resveratrol on L-arginine-induced ANP and the possible mechanisms. A mouse model of ANP was established by 2 hourly intraperitoneal injections of 8% L-arginine (4 g/kg)...

Tumor Treating Fields (TTFields) therapy is an approved treatment that has known clinical efficacy against recurrent and newly diagnosed glioblastoma. However, the distribution of the electric fields and the corresponding pattern of energy deposition in the brain are poorly understood. To evaluate the physical parameters that may influence TTFields, postacquisition MP-RAGE, T1 and T2 MRI sequences from a responder with a right parietal glioblastoma were anatomically segmented and then solved using finite-element method to determine the distribution of the electric fields and rate of energy deposition at the gross tumor volume (GTV) and other intracranial structures...

Hypertriglyceridemia (HTG) aggravates the course of acute pancreatitis (AP). Intestinal barrier dysfunction is implicated in the pathogenesis of AP during which dysbiosis of intestinal microbiota contributes to the dysfunction in intestinal barrier. However, few studies focus on the changes in intestine during HTG-related acute necrotizing pancreatitis (ANP). Here, we investigated the changes in intestinal microbiota and Paneth cell antimicrobial peptides (AMPs) in HTG-related ANP (HANP) in rats. Rats fed a high-fat diet to induce HTG and ANP was induced by retrograde injection of 3...

Oriental medicine Samhwangsasim-tang (SHSST) has traditionally been used in East Asia to treat hypertension and its complications. However, little is known about its potential value regarding the treatment of chronic inflammatory diseases such as multiple sclerosis (MS). In this study, we investigated whether SHSST has a beneficial effect in treating myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis (EAE). Onset-treatment with SHSST was found to alleviate neurological symptoms as well as demyelination and glial activation in the spinal cords from the EAE mice...

Dexmedetomidine (DXM) has anti-inflammatory effects, which is considered an important mechanism of DXM-induced neuroprotection from cerebral ischemia/reperfusion injury. We determined whether the anti-inflammatory effects of DXM are associated with inhibition of the toll-like receptor (TLR)-4/nuclear factor kappa B (NF-κB) pathway in a rat model of transient global cerebral ischemia/reperfusion injury. Fifty rats were randomly assigned to one of five groups (10 rats/group): Group S received no treatment; Group C underwent transient global ischemia (10min); Group D received DXM 30min before ischemia; Group R received resatorvid, a selective TLR-4 antagonist, 30min before ischemia; and Group RD received resatorvid and DXM 30min before ischemia...

Previous investigations suggest that DL-3-n-butylphthalide (NBP) is a promising multifaceted drug for the treatment of stroke. It is not clear whether NBP can treat traumatic brain injury (TBI) and what could be the mechanisms of therapeutic benefits. To address these issues, TBI was induced by a controlled cortical impact in adult male mice. NBP (100 mg/kg) or saline was intraperitoneally administered within 5 min after TBI. One day after TBI, apoptotic events including caspase-3/9 activation, cytochrome c release from the mitochondria, and apoptosis-inducing factor (AIF) translocation into the nucleus in the pericontusion region were attenuated in NBP-treated mice compared to TBI-saline controls...

REVIEW
Luca Di Tommaso, Massimo Roncalli
Few tissue markers are currently available to pathologists in the study of hepatocellular tumors. These markers should be used carefully taking into consideration not only morphology but also, and sometimes even more important, the clinical setting where the lesion to be diagnosed had developed. Glypican-3, heat shock protein 70, and glutamine synthetase (GS) are markers currently used, as a single panel, to discriminate the nature of a <2 cm hepatocellular lesion lacking radiological features of hepatocellular carcinoma (HCC) detected in a cirrhotic patient under surveillance...

PURPOSE: Mathematical modeling is a powerful and flexible method to investigate complex phenomena. It discloses the possibility of reproducing expensive as well as invasive experiments in a safe environment with limited costs. This makes it suitable to mimic tumor evolution and response to radiotherapy although the reliability of the results remains an issue. Complexity reduction is therefore a critical aspect in order to be able to compare model outcomes to clinical data. Among the factors affecting treatment efficacy, tumor oxygenation is known to play a key role in radiotherapy response...
