This paper intend to investigate the effects of biodiesel fuel blends comprising of waste-cooking oil and butanol-diesel (B10W10-B10W40) under steady-state conditions. Both particulate organic carbon (OC) and PM including PM2.5 and PM10 significantly decreased with the increasing percentage of biodiesel fuel blends. The fuel blend of B10W40 also demonstrated the most effective function in reducing the emissions of PM10 and PM2.5 in the volume by 59.4% and 57.7%, respectively. Moreover, the emissions of nitrogen oxides decreased with the blending of B10W10-B10W40 (13...

Epileptic seizures lead to aberrant hippocampal neurogenesis, including increased proliferation of neural progenitors and abnormal integrations of newly generated granule cells - hilar ectopic granule cells (EGCs), mossy fiber sprouting (MFS), and hilar basal dendrites (HBDs). Previous results from ablating hippocampal neurogenesis after acute seizures have been controversial with regards to the development of spontaneous recurrent seizures (SRSs). While ablation of hippocampal newborn cells was effective, a sufficient decrease of subsequent abnormal integrations in chronically epileptic hippocampus was not well-established in these studies...

Toxoplasma gondii possesses a highly polarized secretory system, which efficiently assembles de novo micronemes and rhoptries during parasite replication. These apical secretory organelles release their contents into host cells promoting parasite invasion and survival. Using a CreLox-based inducible knock-out strategy and the ddFKBP over-expression system, we unraveled novel functions of the clathrin adaptor complex TgAP1. First, our data indicate that AP1 in T. gondii likely functions as a conserved heterotetrameric complex composed of the four subunits γ, β, μ1, σ1 and interacts with known regulators of clathrin-mediated vesicular budding such as the unique ENTH-domain containing protein, which we named Epsin-like protein (TgEpsL)...

Many long noncoding RNAs (lncRNAs) are deregulated in cancer and contribute to oncogenesis. In urothelial carcinoma (UC), several lncRNAs have been reported to be overexpressed and proposed as biomarkers. As most reports have not been confirmed independently in large tissue sets, we aimed to validate the diagnostic and prognostic value of lncRNA upregulation in independent cohorts of UC patients. Thus, expression of seven lncRNA candidates (GAS5, H19, linc-UBC1, MALAT1, ncRAN, TUG1, UCA1) was measured by RT-qPCR in cell lines and tissues and correlated to clinicopathological parameters including follow-up data (set 1: N n = 10; T n = 106)...

The treatment of type 1 diabetes mellitus consists of external replacement of the functions of β cells in an attempt to achieve blood levels of glucose as close to the normal range as possible. This approach means that glucose sensing needs to be replaced and levels of insulin need to mimic physiological insulin-action profiles, including basal coverage and changes around meals. Training and educating patients are crucial for the achievement of good glycaemic control, but having insulin preparations with action profiles that provide stable basal insulin coverage and appropriate mealtime insulin peaks helps people with type 1 diabetes mellitus to live active lives without sacrificing tight glycaemic control...

Fatty acids are stored within adipocytes in lipid droplets (LDs) as triacylglycerol (TG), which is converted to free fatty acid (FFA) and glycerol via lipolysis. Increased plasma FFA levels in obesity are associated with several clinical conditions. We previously found that Neu1 activity is aberrant in the epididymal fat and liver of obese and diabetic mice. Here, we examined involvement of Neu1 in lipolysis in 3T3-L1 adipocytes. Small interfering RNA against Neu1 was introduced into adipocytes, and glycerol concentrations were measured in the culture medium...

Hydrogel scaffolds derived from the extracellular matrix (ECM) of mammalian tissues have been successfully used to promote tissue repair in vitro and in vivo. The objective of this study was to evaluate the osteogenic potential of ECM hydrogels prepared from demineralized and decellularized bovine bone in the presence and absence of osteogenic medium. Culture of C2C12 and mouse primary calvarial cells (mPCs) on decellularized bone ECM (bECM) and demineralized bone matrix (DBM) gels resulted in increased expression of osteogenic gene markers, including a 3...

Euglenids (Excavata, Discoba, Euglenozoa, Euglenida) is a group of free-living, single-celled flagellates living in the aquatic environments. The uniting and unique morphological feature of euglenids is the presence of a cell covering called the pellicle. The morphology and organization of the pellicle correlate well with the mode of nutrition and cell movement. Euglenids exhibit diverse modes of nutrition, including phagotrophy and photosynthesis. Photosynthetic species (Euglenophyceae) constitute a single subclade within euglenids...

There is substantial evidence implicating the urokinase system in tissue remodeling during neo-vascularization, inflammation, tumor invasion, and metastasis. Regulated degradation of the extracellular matrix at the leading edge of migrating cells, mediated by uPA and uPAR, is required for tissue remodeling, invasiveness, and angiogenesis. Psoriasis and basal cell carcinoma (BCC) are the most common skin diseases. Pathogenesis of both of them is associated with keratinocyte hyperproliferation, inflammatory cell migration, and angiogenesis-processes in which the plasminogen system (uPA, uPAR, tPA, and PAI-1) plays a crucial role...

The patient was a 79-year-old woman who had received enucleation of right pulmonary papilloma 7 years earlier. She experienced bloody sputum and was therefore referred to our hospital. Chest computed tomography revealed a mass shadow(21 mm) in the right upper lobe (S2). By bronchoscopy, there was no bulging lesion in the visible range. SCC and CEA increased to 6.4 ng/ml and 6.42 ng/ml, respectively. Whole-body 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) showed increased FDG uptake in the region of the right-lung mass shadow (maximum standardized uptake value 12...

The transcription factor early B-cell factor 2 (EBF2) is an essential mediator of brown adipocyte commitment and terminal differentiation. However, the mechanisms by which EBF2 regulates chromatin to activate brown fat-specific genes in adipocytes were unknown. ChIP-seq (chromatin immunoprecipitation [ChIP] followed by deep sequencing) analyses in brown adipose tissue showed that EBF2 binds and regulates the activity of lineage-specific enhancers. Mechanistically, EBF2 physically interacts with the chromatin remodeler BRG1 and the BAF chromatin remodeling complex in brown adipocytes...

Proteins localized to the basal body and the centrosome play crucial roles in ciliary assembly and functions. Although RABL2 and CEP19 are conserved in ciliated organisms and have been implicated in ciliary/flagellar functions, their roles were poorly understood. We here showed that RABL2 interacts with CEP19 and is recruited to the mother centriole and basal body in a CEP19-dependent manner, and that CEP19 is recruited to the centriole probably via its binding to the centrosomal protein FGFR1OP. Disruption of the RABL2 gene in Chlamydomonas reinhardtii resulted in the non-flagellated phenotype, suggesting a crucial role of RABL2 in ciliary/flagellar assembly...

Inositol-requiring enzyme-1α (IRE1α) is an endoplasmic reticulum (ER)-transmembrane endoribonuclease-kinase, which plays an essential function in extraembryonic tissues during normal development, and is activated during ER stress. To address the functional role of IRE1α in glomerular podocytes, we produced podocyte-specific IRE1α deletion mice. In male mice, deletion of IRE1α in podocytes resulted in albuminuria beginning at 5 months of age, and worsening with time. Electron microscopy revealed focal podocyte foot process effacement in 9-month old male IRE1α deletion mice, as well as microvillous transformation of podocyte plasma membranes...

BACKGROUND: Molecular classification of bladder cancer has been increasingly proposed as a potential tool to predict clinical outcomes and responses to chemotherapy. Here we focused on mechanistic target of rapamycin (mTOR) inhibition as a chemotherapeutic strategy and characterized the expression profile of mTOR signaling targets in representative bladder cancer cell lines from basal, luminal, and either basal/luminal ("non-type") molecular subtypes. MATERIALS AND METHODS: Protein and mRNA expression of mTOR signaling components from representative luminal (RT4 and RT112), basal (SCaBER and 5637), and nontype (T24 and J82) bladder cancer cell line subtypes were determined by Western blot and database mining analysis of the Cancer Cell Line Encyclopedia...

BRCA1 deficiency may perturb the differentiation hierarchy present in the normal mammary gland and is associated with the genesis of breast cancers that are genomically unstable and typically display a basal-like transcriptome. Oriented cell division is a mechanism known to regulate cell fates and to restrict tumor formation. We now show that the cell division axis is altered following shRNA-mediated BRCA1 depletion in immortalized but non-tumorigenic, or freshly isolated normal human mammary cells with graded consequences in progeny cells that include aneuploidy, perturbation of cell polarity in spheroid cultures, and a selective loss of cells with luminal features...

Human papillomavirus (HPV)-induced neoplasms have long been considered to originate from viral infection of the basal cell layer of the squamous mucosa. However, this paradigm has been recently undermined by accumulating data supporting the critical role of a discrete population of squamo-columnar (SC) junction cells in the pathogenesis of cervical (pre)cancers. The present review summarizes the current knowledge on junctional cells, discusses their high vulnerability to HPV infection, and stresses the potential clinical/translational value of the novel dualistic model of HPV-related carcinogenesis...

Activity-Based Probes (ABPs) have been used to dissect the biochemical/structural properties and cellular functions of deubiquitinases. However, their utility in studying cysteine-based E3 ubiquitin ligases has so far been limited. In this study, we evaluate the use of Ubiquitin-ABPs (Ub-VME and Ub-PA) and a novel set of E2~Ub-ABPs, on a panel of HECT E3 ubiquitin ligases. Our in vitro data show that ubiquitin-ABPs can label HECT domains and we also provide the first evidence that, in addition to the RBR E3 ubiquitin ligase Parkin, E2~Ub-ABPs can also label the catalytic HECT domain of NEDD4, UBE3C and HECTD1...
