NQO1 and TRXR1 are important host reductases implicated in the regulation of inflammation and apoptosis. Although the transcriptional machinery governing these processes have been extensively investigated, the associated epigenetic regulatory events remain unclear. Here, we report that SET8, a histone H4 lysine 20 monomethylase (H4K20me1), is highly induced during Mycobacterium tuberculosis infection that orchestrates immune evasion strategies through the induction of NQO1 and TRXR1 in vivo. SET8, along with FoxO3a, mediates an active NQO1-PGC1-α complex, which promotes the anti-inflammatory M2 macrophage phenotype, and assists TRXR1-regulated arrest of tumor necrosis factor-related apoptosis-inducing ligand-induced apoptosis...

Background: Extremely drug-resistant (XDR) Acinetobacter baumannii is one of the most commonly encountered, highly resistant pathogens requiring novel therapeutic interventions. Methods: We developed C8, a monoclonal antibody (mAb), by immunizing mice with sublethal inocula of a hypervirulent XDR clinical isolate. Results: C8 targets capsular carbohydrate on the bacterial surface, enhancing opsonophagocytosis. Treating with a single dose of C8 as low as 0...

Background: Previous studies documented that humoral immune responses participated in neurological damage in neurosyphilis patients. However, the mechanisms that trigger and maintain humoral immunity involved in neurosyphilis remain unknown. Methods: Using flow cytometry, expression of B cells was measured in neurosyphilis and non-neurosyphilis. Expression of immunoglobulin indices and chemokine ligand CXCL13 was detected by enzyme-linked immunosorbent assay. The migration and inhibition assays were evaluated by modified chamber assays...

Background: Human papillomavirus (HPV) vaccine was recommended in 2006 for routine vaccination of US females aged 11-12 years. Most vaccine used through 2014 was quadrivalent vaccine (4vHPV), which prevents HPV-6, -11, -16, and -18 infection. To evaluate vaccine impact, we measured HPV prevalence in the National Health and Nutrition Examination Survey (NHANES). Methods: We analyzed HPV DNA types detected in self-collected cervicovaginal specimens and demographic, sexual behavior, and self-reported vaccination data from females 14-34 years old...

Berberine, an important natural isoquinoline alkaloid from traditional Chinese medicine, is reported to exhibit multiple pharmacological properties, including anti-microbial, anti-diabetes, anti-obesity, anti-inflammatory and anti-carcinogenic activities. Although studies have shown that a wide range of carcinoma cells could be inhibited by berberine, few studies involved thyroid carcinoma. We therefore examined the effect of berberine on papillary thyroid carcinoma (PTC, the most common subtype) and anaplastic thyroid carcinoma (ATC, the most malignant and aggressive subtype)...

BACKGROUND: Radiation therapy is commonly used to treat thoracic malignancies. However, it may lead to severe lung pneumonitis and ultimately fibrosis. Irradiation has been reported to increase epithelial-mesenchymal transition (EMT) of type II alveolar epithelial cells (AEC), which play an important role in pulmonary fibrosis. The transforming growth factor-β (TGF-β) and ERK/glycogen synthase kinase 3β (GSK3β) pathways are critically involved in radiation-induced EMT. In the present study, we investigated whether baicalin was a novel therapeutic candidate for radiation-induced EMT in type II AEC...

BACKGROUND: Malignant glioma still has a poor prognosis and remains incurable. Although temozolomide (TMZ) has demonstrated antitumor activity, its use recently has been halted because of some patients' resistance to this drug. New treatments are desperately needed. An oncolytic virus (virotherapy) is being developed as a novel cancer therapy. We have previously reported that recombinant Vesicular Stomatitis Virus (VSV-ΔM51) and double deleted Vaccinia Virus (vvDD) infected and killed glioma cell lines in vitro and prolonged survival in animal glioma models...

In this work, batch enzyme-aided extraction and enzymatic saccharification of blade-milled orange waste was studied. The operation variables for this process were thoroughly analysed. It was determined that batch runs with initial pH values of 5.0 and 5.2 controlled during the first hour, 50°C and 300-500r.p.m. agitation resulted in the best yields, with a limited total and partial first-order enzyme deactivation (for cellulases and polygalacturonidase, respectively). Orange peel waste (OPW) at 6.7% w/w dry solid, 0...

This work aimed to study the feasibility of using bioelectrochemical systems (BES) for organics removal under alkaline-saline and nitrogen (N) deficient conditions. Two BES inoculated with activated sludge were examined for organics (oxalate, acetate, formate) oxidation under alkaline-saline (pH 9.5, 25g/L NaCl) and N deficient conditions. One reactor (R1) received ammonium chloride as an N-source, while the other (R2) without. The reactors were initially loaded with only oxalate (25mM), but start-up was achieved only when acetate was added as co-substrate (5mM)...

Parent support for physical activity (PA) is a behavior unto itself that requires motivation. Persuasive messages may be one method for motivating parent support for their children's PA. Message framing is one strategy for optimizing the impact of messages. The current study examined the relative effectiveness of gain- versus loss-framed messages for encouraging parent support for children's PA. Regardless of message frame, parents had an increase in social cognitive antecedents (e.g. perceived behavioral control, intentions) and support for children's PA following message exposure...

The stink bug Dichelops furcatus (F.) (Heteroptera: Pentatomidae) has increased in abundance in recent years on the wheat, Triticum aestivum L., crop cultivated in the southern region of Brazil. To investigate the probing (stylet penetration) behaviors and nonprobing behaviors of D. furcatus on wheat plants, the electrical penetration graph or electropenetrography (EPG) technique was applied. Nine EPG waveforms (types/subtypes) were identified and described on stem and on ear head of wheat plants, as follows: Z, Np, Df1a, Df1b, Df2, Df3a, Df3b, Df4a, and Df4b...

Temporal niche partitioning may result from interference competition if animals shift their activity patterns to avoid aggressive competitors. If doing so also shifts food sources, it is difficult to distinguish the effects of interference and consumptive competition in selecting for temporal niche shift. Bees compete for pollen and nectar from flowers through both interference and consumptive competition, and some species of bees have evolved nocturnality. Here, we use tropical forest canopy towers to observe bees (the night-flying sweat bees Megalopta genalis and M...

Background: Travellers are at risk of acquiring infectious diseases during travel, with risks differing by destination, travel and traveller characteristics. A pre-travel health consultation may minimize this risk. However, uptake of pre-travel health advice remains low. We investigated pre-travel health preparations and disease-specific risk behaviours among notified cases of selected travel-associated infectious diseases imported into Australia. Methods: Prospective enhanced surveillance of notified cases of typhoid, paratyphoid, measles, hepatitis A, hepatitis E, malaria and chikungunya was conducted in two Australian states between February 2013 and January 2014...

Neurofibromatosis type 1 (NF-1) is a genetic disease with characteristic neurofibromas and bony dysplasia that manifest throughout the body, including the craniofacial region. NF-1 patients are known to frequently report chronic pain in areas below the head; however, the matter of pain in the craniofacial region in this patient group has not been handled intensively so far, and studies have mainly focused on headaches. This article comprehensively reviews the related literature and reports a case of an NF-1 patient whose chief complaint was headache and pain in the temporomandibular joint area...

The majority of cancer patients becomes malnourished during the course of their disease. Malnutrition deteriorates the efficiency of all kinds of oncologic interventions. As a consequence of it, treatment-related toxicity increases, hospital stay is lengthened, chances of cure and survival as well as the quality of life of the patients worsen. Nutritional status therefore influences all aspects of outcome of oncology care. In spite of this the use of nutritional therapy varies across health care providers but its application is far from being sufficient during active oncology interventions as well as rehabilitation and supportive care...
