BAY 11-7082 antagonizes I-κB kinase-β preventing nuclear translocation of NF-κB; it also inhibits NLRP3 inflammasome activation.NF-κB is involved in psoriasis, while the role of NLRP3 is controversial. We investigated BAY 11-7082 effects in an experimental model of psoriasis-like dermatitis. Psoriasis-like lesions were induced by a topical application of imiquimod cream (IMQ; 62.5 mg/day) on the shaved back skin of C57BL/6 and NLRP3 knock-out mice for 7 consecutive days. Sham psoriasis animals were challenged with vaseline cream...

BACKGROUND: NF-κB is one of the key transcription factors in the inflammatory response, transactivates a series of pro-inflammatory genes and is therefore regarded as an important target for anti-inflammatory drug screening. METHOD: We recombined the reporter gene vector with inserting the "neo" transcript into the vector pNF-κB-SEAP, made the reporter gene vector stable in a eukaryotic cell line. The recombinant reporter gene vector we named pNF-κB-SEAP-Neo was transfected into RAW264...

Research documents increased and problematic alcohol use during study abroad experiences for college students yet no research documents effective preventive programs with these students. The present randomized controlled trial was designed to prevent increased and problematic alcohol use abroad by correcting misperceptions of peer drinking norms abroad and by promoting positive and healthy adjustment into the host culture (i.e., sojourner adjustment) through brief online personalized feedback interventions...

This clinical study evaluates end-ischaemic hypothermic machine perfusion (eHMP) in ECD kidneys. eHMP was initiated upon arrival of the kidney in our center and continued until transplantation. Between 11/2011 and 8/2014 eHMP was performed in 66 ECD-kidneys for 369 (98-912) minutes after 863 (364-1567) minutes of CS. In 49 out of 66 cases the contralateral kidney from the same donor was preserved by static cold storage (CS) only and accepted by another Eurotransplant center. Fife (10.2%) of these kidneys were ultimately judged as "not transplantable" by the accepting center and discarded...

Personalized normative feedback (PNF) interventions have been shown to be efficacious at reducing college student drinking. Because descriptive norms have been shown to mediate PNF efficacy, the current study focused on examining additional prototype willingness model social reaction cognitions, namely, prototypes and willingness, as mediators of intervention efficacy. We expected the PNF interventions to be associated with increased prototype favorability of students who do not drink, which would in turn be associated with decreased willingness to drink and subsequently, less drinking...

The use of natural products in wound healing has been extensively studied in the context of complementary and alternative medicine. Propolis, a natural product, is a polyphenol-rich resin used for this purpose. This study aimed to investigate the effect of Brazilian Red Propolis Extract (BRPE) on inflammation and wound healing in mice, using a tissue repair model. The BRPE polyphenol content was analyzed by liquid chromatography coupled to mass spectrometry (LC/MS). A full-thickness excision lesion was created, and mice were treated orally with daily doses of vehicle solution (water-alcohol solution containing 2% of ethanol, control group) or 100mg/kg of BRPE (P100 group) during nine consecutive days...

Gamified interventions exploit the motivational characteristics of a game in order to provide prevention information and promote behavior change. Despite the modest effect sizes observed in increasingly popular web-based personalized normative feedback (PNF) alcohol interventions for college students, previous research has yet to consider how gamification might be used to enhance efficacy. This study examines whether a novel, gamified PNF intervention format, which includes a point-based reward system, the element of chance, and personal icons to visually represent users, is more effective in reducing short-term alcohol use than the standard web-based style of PNF currently used on college campuses...

While cerebrospinal fluid (CSF) biomarkers for Creutzfeldt-Jakob disease (CJD) are established and partly included in the diagnostic criteria, no blood biomarkers are available. Here, we assessed the utility of serum neurofilament light chain (NF-L) and tau protein in comparison to CSF markers (NF-L and phosphorylated NF heavy chain (pNF-H), tau, S100B, 14-3-3) and prion conversion assay (real-time quaking induced conversion (RT-QuIC)) for sporadic and genetic CJD. Importantly, a Gerstmann-Sträussler-Scheinker mutation carrier in the asymptomatic phase and at disease onset was included as well...

BACKGROUND: Extracellular histones are cytotoxic molecules that are related to cell stress and death. They have been shown to play a crucial role in multiple pathophysiologic processes like sepsis, inflammation, vascular dysfunction and thrombosis. Their role in organ donation and graft function and survival is still unknown. The aim of this study was to assess whether an association exists between the presence of extracellular histones in machine perfusates and deceased donor kidney viability...

In this paper, we aim to investigate the effect of proprioceptive neuromuscular facilitation (PNF)-based rehabilitation for ankle plantar flexors spasticity by using a Robotic Ankle-foot Rehabilitation System (RARS). A modified robot-assisted system was proposed, and seven poststroke patients with hemiplegic spastic ankles participated in a 3-month robotic PNF training. Their impaired sides were used as the experimental group, while their unimpaired sides as the control group. A robotic intervention for the experimental group started from a 2-min passive stretching to warming-up or relaxing the soleus and gastrocnemius muscles and also ended with the same one...

Entamoeba histolytica is the causative agent of amoebic liver abscess (ALA), which course with an uncontrolled inflammation and nitro-oxidative stresses, although it is well known that amoeba has an effective defence mechanisms against this toxic environment, the underlying molecular factors responsible for progression of tissue damage remain largely unknown. The purpose of the present study was to determine during the acute stage of ALA in hamsters, the involvement of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and nuclear factor-kappa B (NF-κB), which are activated in response to oxidative stress...

Axonal transport deficits precede structural loss in glaucoma and other neurodegenerations. Impairments in structural support, including modified cytoskeletal proteins, and microtubule-destabilizing elements, could be initiating factors in glaucoma pathogenesis. We investigated the time course of changes in protein levels and post-translational modifications in the DBA/2J mouse model of glaucoma. Using anterograde tract tracing of the retinal projection, we assessed major cytoskeletal and transported elements as a function of transport integrity in different stages of pathological progression...

This study examined the efficacy of a personalized normative feedback (PNF) alcohol intervention for parents of students transitioning into college. A sample of 399 parent-student dyads were recruited to take part in the intervention during the summer prior to matriculation. Parents were randomly assigned to receive either normative feedback regarding student drinking and other college parents' alcohol-related communication or general college health norm information. Students completed measures of alcohol use, alcohol consequences, and parent-child alcohol-specific communication both 1 and 6 months after matriculation...

NLRP3 (NOD-like receptor family, pyrin domain containing 3) is a member of the inflammasome family and is of special interest in renal disease. Experimental studies have shown that Nlrp3 plays a significant role in the induction of renal damage and dysfunction in acute and chronic renal injury. However, the role of NLRP3 in human renal disease is completely unknown. From a retrospective cohort study, we determined in 1271 matching donor and recipient samples if several NLRP3 single nucelotide polymorphisms (SNPs) were associated with primary non-function (PNF), delayed graft function (DGF), biopsy-proven acute rejection (BPAR) and death-censored graft and patient survival...

It has been proposed that depression is associated with dysfunction of hippocampal plasticity. Novel hypotheses suggest that antidepressants induce neuronal structural plasticity, although the underlying mechanisms still remain unclear. Therefore, the aim of this study was to investigate the effects of amitriptyline on levels of phosphorylated heavy neurofilament subunit (NF-H) in the hippocampus of mice exposed to acute and chronic behavioral despair paradigms. Immunoblotting experiments showed that animals exposed to the tail suspension test (TST) displayed diminished levels of pNF-H 24h after testing...

BACKGROUND: Obesity has been associated with worse outcomes and increased surgical technical difficulty. Perinephric fat (PNF) and periumbilical fat (PUF) are alternative metrics to body mass index. We hypothesized that PUF and PNF would offer improved prediction of perioperative risk. METHODS: 249 patients were retrospectively reviewed after elective, pelvic colorectal resections. PNF and PUF were collected using axial imaging. Operative risk measurements included estimated blood loss (EBL) and operative time (OT)...

BACKGROUND/OBJECTIVE: To determine whether inflammation increases in retina as it does in brain following middle cerebral artery occlusion (MCAO), and whether the neurosteroid progesterone, shown to have protective effects in both retina and brain after MCAO, reduces inflammation in retina as well as brain. METHODS: MCAO rats treated systemically with progesterone or vehicle were compared with shams. Protein levels of cytosolic NF-κB, nuclear NF-κB, phosphorylated NF-κB, IL-6, TNF-α, CD11b, progesterone receptor A and B, and pregnane X receptor were assessed in retinas and brains at 24 and 48 h using western blots...

BACKGROUND: The role of exercise therapy in improving pain-related clinical outcomes and trunk muscle activity in patients with chronic low back pain (CLBP) has been widely reported. There is little information on the effect of proprioceptive neuromuscular facilitation (PNF) training in patients with CLBP. The purpose of the present study was therefore to investigate the persistence of the effects of PNF training on pain intensity, functional disability, patient satisfaction, health-related quality of life (HRQOL) and lower back muscle activity in patients with CLBP...

The role of donation after cardiac death (DCD) in expanding the donor pool is mainly limited by the incidence of primary nonfunction (PNF) and ischemia-related complications. Even greater concern exists toward uncontrolled DCD, which represents the largest potential pool of DCD donors. We recently started the first Italian series of DCD liver transplantation, using normothermic regional perfusion (NRP) in 6 uncontrolled donors and in 1 controlled case to deal with the legally required no-touch period of 20 minutes...

BACKGROUND: The two main options for renal allograft preservation are static cold storage (CS) and machine perfusion (MP). There has been considerably increased interest in MP preservation of kidneys, however conflicting evidence regarding its efficacy and associated costs have impacted its scale of clinical uptake. Additionally, there is no clear consensus regarding oxygenation, and hypo- or normothermia, in conjunction with MP, and its mechanisms of action are also debated. The primary aims of this article were to elucidate the benefits of MP preservation with and without oxygenation, and/or under normothermic conditions, when compared with CS prior to deceased donor kidney transplantation...
