Inhalation tests are the gold standard test for the estimation of the pulmonary toxicity of respirable materials. Intratracheal instillation tests have been used widely, but they yield limited evidence of the harmful effects of respirable materials. We reviewed the effectiveness of intratracheal instillation tests for estimating the hazards of nanomaterials, mainly using research papers featuring intratracheal instillation and inhalation tests centered on a Japanese national project. Compared to inhalation tests, intratracheal instillation tests induced more acute inflammatory responses in the animal lung due to a bolus effect regardless of the toxicity of the nanomaterials. However, nanomaterials with high toxicity induced persistent inflammation in the chronic phase, and nanomaterials with low toxicity induced only transient inflammation. Therefore, in order to estimate the harmful effects of a nanomaterial, an observation period of 3 months or 6 months following intratracheal instillation is necessary. Among the endpoints of pulmonary toxicity, cell count and percentage of neutrophil, chemokines for neutrophils and macrophages, and oxidative stress markers are considered most important. These markers show persistent and transient responses in the lung from nanomaterials with high and low toxicity, respectively. If the evaluation of the pulmonary toxicity of nanomaterials is performed in not only the acute but also the chronic phase in order to avoid the bolus effect of intratracheal instillation and inflammatory-related factors that are used as endpoints of pulmonary toxicity, we speculate that intratracheal instillation tests can be useful for screening for the identification of the hazard of nanomaterials through pulmonary inflammation.

Objective: To study immunological effects of depleted uranium in rats. Methods: Wistar rats were exposed to depleted uranium by single intratracheal instillation. Body weight and peripheral blood cells were measured weekly and immunological functions were evaluated by weight coefficient of immune organs, plague forming cells of splenocytes, total and subpopulation counts of lymphocytes in thymus. Results: Early after administration, body weight decreased and red blood cells as well as platelets reduced while white blood cells increased, which returned to normal within 1 or 2 months. Immunological functions of splenocytes and thymocytes were affected dose-dependently by depleted uranium. Conclusion: Depleted uranium induces immunological dysfunction in rats. (authors)

Full Text Available Abstract Background We used fullerenes, whose dispersion at the nano-level was stabilized by grinding in nitrogen gas in an agitation mill, to conduct an intratracheal instillation study and an inhalation exposure study. Fullerenes were individually dispersed in distilled water including 0.1% Tween 80, and the diameter of the fullerenes was 33 nm. These suspensions were directly injected as a solution in the intratracheal instillation study. The reference material was nickel oxide in distilled water. Wistar male rats intratracheally received a dose of 0.1 mg, 0.2 mg, or 1 mg of fullerenes and were sacrificed after 3 days, 1 week, 1 month, 3 months, and 6 months. In the inhalation study, Wistar rats were exposed to fullerene agglomerates (diameter: 96 ± 5 nm; 0.12 ± 0.03 mg/m3; 6 hours/days for 5 days/week for 4 weeks and were sacrificed at 3 days, 1 month, and 3 months after the end of exposure. The inflammatory responses and gene expression of cytokine-induced neutrophil chemoattractants (CINCs were examined in rat lungs in both studies. Results In the intratracheal instillation study, both the 0.1 mg and 0.2 mg fullerene groups did not show a significant increase of the total cell and neutrophil count in BALF or in the expression of CINC-1,-2αβ and-3 in the lung, while the high-dose, 1 mg group only showed a transient significant increase of neutrophils and expression of CINC-1,-2αβ and -3. In the inhalation study, there were no increases of total cell and neutrophil count in BALF, CINC-1,-2αβ and-3 in the fullerene group. Conclusion These data in intratracheal instillation and inhalation studies suggested that well-dispersed fullerenes do not have strong potential of neutrophil inflammation.

We performed inhalation and intratracheal instillation studies of cerium dioxide (CeO{sub 2}) nanoparticles in order to investigate their pulmonary toxicity, and observed pulmonary inflammation not only in the acute and but also in the chronic phases. In the intratracheal instillation study, F344 rats were exposed to 0.2 mg or 1 mg of CeO{sub 2} nanoparticles. Cell analysis and chemokines in bronchoalveolar lavage fluid (BALF) were analyzed from 3 days to 6 months following the instillation. In the inhalation study, rats were exposed to the maximum concentration of inhaled CeO{sub 2} nanoparticles (2, 10 mg/m{sup 3}, respectively) for 4 weeks (6 h/day, 5 days/week). The same endpoints as in the intratracheal instillation study were examined from 3 days to 3 months after the end of the exposure. The intratracheal instillation of CeO{sub 2} nanoparticles caused a persistent increase in the total and neutrophil number in BALF and in the concentration of cytokine-induced neutrophil chemoattractant (CINC)-1, CINC-2, chemokine for neutrophil, and heme oxygenase-1 (HO-1), an oxidative stress marker, in BALF during the observation time. The inhalation of CeO{sub 2} nanoparticles also induced a persistent influx of neutrophils and expression of CINC-1, CINC-2, and HO-1 in BALF. Pathological features revealed that inflammatory cells, including macrophages and neutrophils, invaded the alveolar space in both studies. Taken together, the CeO{sub 2} nanoparticles induced not only acute but also chronic inflammation in the lung, suggesting that CeO{sub 2} nanoparticles have a pulmonary toxicity that can lead to irreversible lesions.

In order to investigate the pulmonary toxicity of titanium dioxide (TiO 2 ) nanoparticles, we performed an intratracheal instillation study with rats of well-dispersed TiO 2 nanoparticles and examined the pulmonary inflammation and histopathological changes in the lung. Wistar Hannover rats were intratracheally administered 0.2 mg (0.66 mg/kg) and 1.0 mg (3.3 mg/kg) of well-dispersed TiO 2 nanoparticles (P90; diameter of agglomerates: 25 nm), then the pulmonary inflammation responses were examined from 3 days to 6 months after the instillation, and the pathological features were examined up to 24 months. Transient inflammation and the upregulation of chemokines in the broncho-alveolar lavage fluid were observed for 1 month. No respiratory tumors or severe fibrosis were observed during the recovery time. These data suggest that transient inflammation induced by TiO 2 may not lead to chronic, irreversible legions in the lung, and that TiO 2 nanoparticles may not have a high potential for lung disorder

Sympathoadrenergic responses during emergence and extubation can lead to an increase in heart rate (HR) and blood pressure whereas increased airway responses may lead to coughing and laryngospasm. The aim of our study was to compare the effects of lignocaine administered intravenously (IV) or intratracheally on airway and hemodynamic responses during emergence and extubation in patients undergoing elective craniotomies. Sixty patients with physical status American Society of Anaesthesiologists Classes I and II aged 18-70 years, scheduled to undergo elective craniotomies were included. The patients were randomly divided into three groups of twenty patients; Group 1 receiving IV lignocaine and intratracheal placebo (IV group), Group 2 receiving intratracheal lignocaine and IV placebo (I/T group), and Group 3 receiving IV and intratracheal placebo (placebo group). The tolerance to the endotracheal tube was monitored, and number of episodes of cough was recorded during emergence and at the time of extubation. Hemodynamic parameters such as HR and blood pressure (systolic, diastolic, mean arterial pressure) were also recorded. There was a decrease of HR in both IV and intratracheal groups in comparison with placebo group ( P < 0.005). Rise in blood pressure (systolic blood pressure, diastolic blood pressure and mean arterial pressure) was comparable in both Groups 1 and 2 but was lower in comparison with placebo group ( P < 0.005). Cough suppression was comparable in all the three groups. Grade III cough (15%) was documented only in placebo group. Both IV and intratracheal lignocaine are effective in attenuation of hemodynamic response if given within 20 min from skull pin removal to extubation. There was comparable cough suppression through intratracheal route and IV routes than the placebo group.

Repeated intratracheal instillations of E. coli lipopolysaccharide (LPS) in hamster lungs cause an influx of polymorphonuclear leukocytes (PMNs) into the alveolar walls, with concomitant development of severe emphysema. It has been suggested that elastase, released by these PMNs, is involved in the development of emphysema. This study demonstrates the release of elastase from recruited PMNs in cryostat sections of hamster lungs, after being treated once, twice, or thrice with LPS, intratracheally. Elastase activity was visualized using two elastase-specific synthetic substrates, to which a methoxynaphthylamine (MNA) group had been bound covalently. Liberated MNA, when made insoluble by coupling with 5-nitrosalicylaldehyde, fluoresces strongly. The authors observed that the interval between start of incubation and appearance of fluorescence and the intensity of fluorescence correlated with the number of LPS administrations. Fluorescence was observed to be located in or in close vicinity to alveolar walls. No fluorescence was observed in sections of untreated hamsters. Liberation of MNA from synthetic substrates was delayed strongly by the addition of a recombinant secretory leukocyte proteinase inhibitor or a substituted cephalosporin neutrophil elastase inhibitor. The authors conclude that LPS-mediated PMN influx into the lung is accompanied by release of elastase from these cells and speculate that this PMN-elastase is involved in the development of LPS-mediated emphysema.

Silica nanoparticles (NPs) incorporating cadmium (Cd) have been developed for a range of potential application including drug delivery devices. Occupational Cd inhalation has been associated with emphysema, pulmonary fibrosis and lung tumours. Mechanistically, Cd can induce oxidative stress and mediate cell-signalling pathways that are involved in inflammation.This in vivo study aimed at investigating pulmonary molecular effects of NPs doped with Cd (NP-Cd, 1 mg/animal) compared to soluble CdCl 2 (400 μg/animal), in Sprague Dawley rats treated intra-tracheally, 7 and 30 days after administration. NPs of silica containing Cd salt were prepared starting from commercial nano-size silica powder (HiSil T M T700 Degussa) with average pore size of 20 nm and surface area of 240 m 2 /g. Toxicogenomic analysis was performed by the DNA microarray technology (using Agilent Whole Rat Genome Microarray 4x44K) to evaluate changes in gene expression of the entire genome. These findings indicate that the whole genome analysis may represent a valuable approach to assess the whole spectrum of biological responses to cadmium containing nanomaterials.

Serum and bronchoalveolar fluid IL-6 are increased in patients with acute respiratory distress syndrome (ARDS) and predict prolonged mechanical ventilation and poor outcomes, although the role of intra-alveolar IL-6 in indirect lung injury is unknown. We investigated the role of endogenous and exogenous intra-alveolar IL-6 in AKI-mediated lung injury (indirect lung injury), intraperitoneal (IP) endotoxin administration (indirect lung injury) and, for comparison, intratracheal (IT) endotoxin administration (direct lung injury) with the hypothesis that IL-6 would exert a pro-inflammatory effect in these causes of acute lung inflammation. Bronchoalveolar cytokines (IL-6, CXCL1, TNF-α, IL-1β, and IL-10), BAL fluid neutrophils, lung inflammation (lung cytokines, MPO activity [a biochemical marker of neutrophil infiltration]), and serum cytokines were determined in adult male C57Bl/6 mice with no intervention or 4 hours after ischemic AKI (22 minutes of renal pedicle clamping), IP endotoxin (10 µg), or IT endotoxin (80 µg) with and without intratracheal (IT) IL-6 (25 ng or 200 ng) treatment. Lung inflammation was similar after AKI, IP endotoxin, and IT endotoxin. BAL fluid IL-6 was markedly increased after IT endotoxin, and not increased after AKI or IP endotoxin. Unexpectedly, IT IL-6 exerted an anti-inflammatory effect in healthy mice characterized by reduced BAL fluid cytokines. IT IL-6 also exerted an anti-inflammatory effect in IT endotoxin characterized by reduced BAL fluid cytokines and lung inflammation; IT IL-6 had no effect on lung inflammation in AKI or IP endotoxin. IL-6 exerts an anti-inflammatory effect in direct lung injury from IT endotoxin, yet has no role in the pathogenesis or treatment of indirect lung injury from AKI or IP endotoxin. Since intra-alveolar inflammation is important in the pathogenesis of direct, but not indirect, causes of lung inflammation, IT anti-inflammatory treatments may have a role in direct, but not indirect, causes of ARDS.

To elucidate the pathogenesis and transmission of influenza virus, the ferret model is typically used. To investigate protective immune responses, the use of inbred mouse strains has proven invaluable. Here, we describe a study with isogenic guinea pigs, which would uniquely combine the advantages of the mouse and ferret models for influenza virus infection. Strain 2 isogenic guinea pigs were inoculated with H1N1pdm09 influenza virus A/Netherlands/602/09 by the intranasal or intratracheal route. Viral replication kinetics were assessed by determining virus titers in nasal swabs and respiratory tissues, which were also used to assess histopathologic changes and the number of infected cells. In all guinea pigs, virus titers peaked in nasal secretions at day 2 after inoculation. Intranasal inoculation resulted in higher virus excretion via the nose and higher virus titers in the nasal turbinates than intratracheal inoculation. After intranasal inoculation, infectious virus was recovered only from nasal epithelium; after intratracheal inoculation, it was recovered also from trachea, lung, and cerebrum. Histopathologic changes corresponded with virus antigen distribution, being largely limited to nasal epithelium for intranasally infected guinea pigs and more widespread in the respiratory tract for intratracheally infected guinea pigs. In summary, isogenic guinea pigs show promise as a model to investigate the role of humoral and cell-mediated immunities to influenza and their effect on virus transmission.

Mycoplasma gallisepticum is the most important pathogen in poultry among four pathogenic Mycoplasma species. Tiamulin is a pleuromutilin antibiotic that shows a great activity against M. gallisepticum and has been approved for use in veterinary medicine particularly for poultry. However, the pharmacokinetic/pharmacodynamics (PK/PD) profiles of tiamulin against M. gallisepticum are not well understood. Therefore, in the current studies, we investigated the in vivo PK/PD profiles of tiamulin using a well-established experimental intratracheal infection model of M. gallisepticum. The efficacy of tiamulin against M. gallisepticum was studied in 8-day-old chickens after intramuscular (i.m.) administration at 10 doses between 0-80 mg/kg. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to evaluate the PK parameters of tiamulin following i.m. administration at doses of 5, 40, and 80 mg/kg in Mycoplasma gallisepticum-infected neutropenic chickens. Real-time PCR (RT-PCR) was used for quantitative detection of M. gallisepticum. The MIC of tiamulin against M. gallisepticum strain S6 was 0.03 μg/mL. The PK/PD index, AUC24h/MIC, correlated well with the in vivo antibacterial efficacy. The in vivo data suggest that animal dosage regimens should supply AUC24h/MIC of tiamulin of 382.68 h for 2 log10 ccu equivalents M. gallisepticum reduction. To attain that goal, the administered dose is expected to be 45 mg/kg b.w. for treatment of M. gallisepticum infection with an MIC90 of 0.03 μg/mL.

Full Text Available We investigated the protective efficacy of two intranasal chitosan (CSN and TM-CSN adjuvanted H5N1 Influenza vaccines against highly pathogenic avian Influenza (HPAI intratracheal and intranasal challenge in a ferret model. Six groups of 6 ferrets were intranasally vaccinated twice, 21 days apart, with either placebo, antigen alone, CSN adjuvanted antigen, or TM-CSN adjuvanted antigen. Homologous and intra-subtypic antibody cross-reacting responses were assessed. Ferrets were inoculated intratracheally (all treatments or intranasally (CSN adjuvanted and placebo treatments only with clade 1 HPAI A/Vietnam/1194/2004 (H5N1 virus 28 days after the second vaccination and subsequently monitored for morbidity and mortality outcomes. Clinical signs were assessed and nasal as well as throat swabs were taken daily for virology. Samples of lung tissue, nasal turbinates, brain, and olfactory bulb were analysed for the presence of virus and examined for histolopathological findings. In contrast to animals vaccinated with antigen alone, the CSN and TM-CSN adjuvanted vaccines induced high levels of antibodies, protected ferrets from death, reduced viral replication and abrogated disease after intratracheal challenge, and in the case of CSN after intranasal challenge. In particular, the TM-CSN adjuvanted vaccine was highly effective at eliciting protective immunity from intratracheal challenge; serologically, protective titres were demonstrable after one vaccination. The 2-dose schedule with TM-CSN vaccine also induced cross-reactive antibodies to clade 2.1 and 2.2 H5N1 viruses. Furthermore ferrets immunised with TM-CSN had no detectable virus in the respiratory tract or brain, whereas there were signs of virus in the throat and lungs, albeit at significantly reduced levels, in CSN vaccinated animals. This study demonstrated for the first time that CSN and in particular TM-CSN adjuvanted intranasal vaccines have the potential to protect against significant

Bleomycin, an antineoplastic drug, is known to produce interstitial pulmonary fibrosis (IPF). As a result, it is commonly employed in various species to produce animal models of fibrosis. We have examined the uptake of [ 14 C] acetate by lung slices and its incorporation into lipids in the slices at various times following intratracheal administration of a fibrogenic dose of bleomycin in hamsters. As compared to saline controls, bleomycin had no effect on [ 14 C] acetate uptake at 4 and 7 days but it increased the uptake at 2 and 14 days after treatment. The incorporation of [ 14 C] acetate into total lipid was significantly reduced to 44, 62, 62, and 75% of the control at 2, 4, 7, and 14 days after bleomycin treatment, respectively. The incorporation into lipid as a percentage of the uptake was 12.2 in control animals whereas in bleomycin-treated animals, it was 4.7, 8.0, 7.3, and 6.9 at the corresponding times. Separation of lipids into various fractions revealed that bleomycin treatment specifically inhibited the synthesis of phosphatidylcholine and neutral lipid at all times of the study. The synthesis of all other phospholipids except phosphatidylethanolamine was depressed at 2 days. The latter was, however, depressed at 7 and 14 days after bleomycin treatment. It was concluded from the present study that bleomycin treatment inhibits the synthesis of phospholipid and neutral lipid and this may eventually lead to decreased surfactant production

The retention, tissue distribution, and excretion of 191 Pt in adult rats was determined following oral, intravenous (IV), and intratracheal administration. The highest retention was obtained following IV dosing, and lowest retention (less than 0.5 percent) occurred after oral dosing. Tissues containing the highest concentrations of 191 Pt following IV administration were the kidney, adrenal, spleen, and liver. Following a single oral dose, almost all of the 191 Pt was excreted in the feces due to nonabsorption, whereas after IV dosing, similar quantities were excreted in both the urine and feces. Following IV dosing of pregnant rats, 191 Pt was found in all the fetuses; however, the amount was small

The aim of this study was to investigate whether intratracheal allogeneic transplantation of bone-marrow-derived EPCs would attenuate the development of smoking-induced COPD in mice.Methods: Isolated mononuclear cells from the bone marrow of C57BL/6J mice were cultured in endothelial cell growth medium-2 for 10 days, yielding EPCs. A murine model of COPD was established by passive 90-day exposure of cigarette smoke. On day 30, EPCs or phosphate-buffered saline alone was administered into the trachea. On day 90, EPCs or 30 µL phosphate-buffered saline alone was administered into the trachea, and on day 120, inflammatory cells, antioxidant activity, apoptosis, matrix metalloproteinase (MMP-2, and MMP-9 were measured.Results: After EPC treatment, the lung function of the mice had improved compared with the untreated mice. Mean linear intercept and destructive index were reduced in the EPCs-treated group compared with the untreated group. In addition, the EPCs-treated mice exhibited less antioxidant activity in bronchoalveolar lavage fluid compared with the untreated mice. Moreover, decreased activities of MMP-2, MMP-9, and TUNEL-positive cells in lung tissues were detected in EPCs-treated mice.Conclusion: Intratracheal transplantation of EPCs attenuated the development of pulmonary emphysema and lung function disorder probably by alleviating inflammatory infiltration, decelerating apoptosis

An unusual case of recurrent pregnancy-related thyroid growth stimulation is reported. A 27-year-old euthyroid woman had pulmonary symptoms, thought to be asthma during her first pregnancy, that improved postpartum. Bronchodilatators had no effect and symptoms recurred from gestational week 22...... during her second pregnancy. Her 58-mL multinodular goiter (by ultrasound) was not thought to be responsible for her upper airway symptoms. Therefore, fiber laryngoscopy and computed tomographic (CT) scan were performed and revealed a 20 x 15 x 10 mm intratracheal tumor. After tracheostomy...... developed normally. We believe that this case illustrates the recurrent effect of pregnancy-related thyroid tissue stimulation by a combination of increasing human chorionic gonadotropin (hCG) stimulation and iodine deficiency in a borderline iodine-deficient region. This is the first report on symptomatic...

Mechanical ventilation (MV) is an essential supportive therapy for acute lung injury (ALI); however it can also contribute to systemic inflammation. Since pulmonary surfactant has anti-inflammatory properties, the aim of the study was to investigate the effect of exogenous surfactant administration on ventilation-induced systemic inflammation. Mice were randomized to receive an intra-tracheal instillation of a natural exogenous surfactant preparation (bLES, 50 mg/kg) or no treatment as a control. MV was then performed using the isolated and perfused mouse lung (IPML) set up. This model allowed for lung perfusion during MV. In experiment 1, mice were exposed to mechanical ventilation only (tidal volume =20 mL/kg, 2 hours). In experiment 2, hydrochloric acid or air was instilled intra-tracheally four hours before applying exogenous surfactant and ventilation (tidal volume =5 mL/kg, 2 hours). For both experiments, exogenous surfactant administration led to increased total and functional surfactant in the treated groups compared to the controls. Exogenous surfactant administration in mice exposed to MV only did not affect peak inspiratory pressure (PIP), lung IL-6 levels and the development of perfusate inflammation compared to non-treated controls. Acid injured mice exposed to conventional MV showed elevated PIP, lung IL-6 and protein levels and greater perfusate inflammation compared to air instilled controls. Instillation of exogenous surfactant did not influence the development of lung injury. Moreover, exogenous surfactant was not effective in reducing the concentration of inflammatory cytokines in the perfusate. The data indicates that exogenous surfactant did not mitigate ventilation-induced systemic inflammation in our models. Future studies will focus on altering surfactant composition to improve its immuno-modulating activity.

Herein, we examine if a single intratracheal instillation of CeO2 nanoparticles is associated with systemic toxicity in male Sprague-Dawley rats.Methods and results: Compared with control animals, CeO2 nanoparticle exposure was associated with increased liver ceria levels, elevations in serum alanine transaminase levels, reduced albumin levels, a diminished sodium-potassium ratio, and decreased serum triglyceride levels (P < 0.05. Consistent with these data, rats exposed to CeO2 nanoparticles also exhibited reductions in liver weight (P < 0.05 and dose-dependent hydropic degeneration, hepatocyte enlargement, sinusoidal dilatation, and accumulation of granular material. No histopathological alterations were observed in the kidney, spleen, and heart. Analysis of serum biomarkers suggested an elevation of acute phase reactants and markers of hepatocyte injury in the rats exposed to CeO2 nanoparticles.Conclusion: Taken together, these data suggest that

Mucormycosis is a life-threatening fungal infection almost uniformly affecting diabetics in ketoacidosis or other forms of acidosis and/or immunocompromised patients. Inhalation of Mucorales spores provides the most common natural route of entry into the host. In this study, we developed an intratracheal instillation model of pulmonary mucormycosis that hematogenously disseminates into other organs using diabetic ketoacidotic (DKA) or cyclophosphamide-cortisone acetate-treated mice. Various degrees of lethality were achieved for the DKA or cyclophosphamide-cortisone acetate-treated mice when infected with different clinical isolates of Mucorales. In both DKA and cyclophosphamide-cortisone acetate models, liposomal amphotericin B (LAmB) or posaconazole (POS) treatments were effective in improving survival, reducing lungs and brain fungal burdens, and histologically resolving the infection compared with placebo. These models can be used to study mechanisms of infection, develop immunotherapeutic strategies, and evaluate drug efficacies against life-threatening Mucorales infections. PMID:23650163

Incorporation of engineered nanomaterials (ENMs) into toners used in laser printers has led to countless quality and performance improvements. However, the release of ENMs during printing (consumer use) has raised concerns about their potential adverse health effects. The aim of this study was to use "real world" printer-emitted particles (PEPs), rather than raw toner powder, and assess the pulmonary responses following exposure by intratracheal instillation. Nine-week old male Balb/c mice were exposed to various doses of PEPs (0.5, 2.5 and 5 mg/kg body weight) by intratracheal instillation. These exposure doses are comparable to real world human inhalation exposures ranging from 13.7 to 141.9 h of printing. Toxicological parameters reflecting distinct mechanisms of action were evaluated, including lung membrane integrity, inflammation and regulation of DNA methylation patterns. Results from this in vivo toxicological analysis showed that while intratracheal instillation of PEPs caused no changes in the lung membrane integrity, there was a pulmonary immune response, indicated by an elevation in neutrophil and macrophage percentage over the vehicle control and low dose PEPs groups. Additionally, exposure to PEPs upregulated expression of the Ccl5 ( Rantes ), Nos1 and Ucp2 genes in the murine lung tissue and modified components of the DNA methylation machinery ( Dnmt3a ) and expression of transposable element (TE) LINE-1 compared to the control group. These genes are involved in both the repair process from oxidative damage and the initiation of immune responses to foreign pathogens. The results are in agreement with findings from previous in vitro cellular studies and suggest that PEPs may cause immune responses in addition to modifications in gene expression in the murine lung at doses that can be comparable to real world exposure scenarios, thereby raising concerns of deleterious health effects.

DNA adducts were isolated and characterized in mouse lung, liver and kidney after intratracheal instillation of [ 3 H]-1-nitropyrene (1-NP). HPLC analysis of the enzymatically digested DNA indicated the presence of multiple DNA adducts in mouse lung, liver and kidney. These results indicate that DNA adducts of 1-NP are formed in mouse lung, liver and kidney after intratracheal instillation of 1-NP; the HPLC profiles of the multiple adducts suggests that adducts may be formed via metabolic pathways that involve both nitroreduction and ring-oxidation. 6 references, 1 figure

3-Nitrobenzanthrone (3-NBA), a carcinogenic air pollutant, was investigated for its ability to induce cytochrome P450 (CYP) 1A1/2 and NAD(P)H:quinone oxidoreductase (NQO1) in liver, kidney and lung of rats treated by intra-tracheal instillation. The organs used were from a previous study performed to determine the persistence of 3-NBA-derived DNA adducts in target and non-target tissues (Bieler et al., Carcinogenesis 28 (2007) 1117-1121, [22]). NQO1 is the enzyme reducing 3-NBA to N-hydroxy-3-aminobenzanthrone (N-OH-3-ABA) and CYP1A enzymes oxidize a human metabolite of 3-NBA, 3-aminobenzanthrone (3-ABA), to yield the same reactive intermediate. 3-NBA and 3-ABA are both activated to species forming DNA adducts by cytosols and/or microsomes isolated from rat lung, the target organ for 3-NBA carcinogenicity, and from liver and kidney. Each compound generated the same five DNA adducts detectable by (32)P-postlabelling. When hepatic cytosols from rats treated with 0.2 or 2mg/kg body weight of 3-NBA were incubated with 3-NBA, DNA adduct formation was 3.2- and 8.6-fold higher, respectively, than in incubations with cytosols from control animals. Likewise, cytosols isolated from lungs and kidneys of rats exposed to 3-NBA more efficiently activated 3-NBA than those of control rats. This increase corresponded to an increase in protein levels and enzymatic activities of NQO1. Incubations of hepatic, pulmonary or renal microsomes of 3-NBA-treated rats with 3-ABA led to an 9.6-fold increase in DNA-adduct formation relative to controls. The highest induction in DNA-adduct levels was found in lung. The stimulation of DNA-adduct formation correlated with expression of CYP1A1/2 induced by the intra-tracheal instillation of 3-NBA. The results demonstrate that 3-NBA induces NQO1 and CYP1A1/2 in livers, lungs and kidneys of rats after intra-tracheal instillation, thereby enhancing its own genotoxic and carcinogenic potential.

Pulmonary Toxicity, Distribution, and Clearance of Intratracheally Instilled Silicon Nanowires in Rats

Directory of Open Access Journals (Sweden)

Jenny R. Roberts

2012-01-01

Full Text Available Silicon nanowires (Si NWs are being manufactured for use as sensors and transistors for circuit applications. The goal was to assess pulmonary toxicity and fate of Si NW using an in vivo experimental model. Male Sprague-Dawley rats were intratracheally instilled with 10, 25, 50, 100, or 250 μg of Si NW (~20–30 nm diameter; ~2–15 μm length. Lung damage and the pulmonary distribution and clearance of Si NW were assessed at 1, 3, 7, 28, and 91 days after-treatment. Si NW treatment resulted in dose-dependent increases in lung injury and inflammation that resolved over time. At day 91 after treatment with the highest doses, lung collagen was increased. Approximately 70% of deposited Si NW was cleared by 28 days with most of the Si NW localized exclusively in macrophages. In conclusion, Si NW induced transient lung toxicity which may be associated with an early rapid particle clearance; however, persistence of Si NW over time related to dose or wire length may lead to increased collagen deposition in the lung.

Pulmonary alveolar macrophages (PAM) from donor rats were intratracheally instilled into recipient rats to determine if donor macrophages were functionally similar to the recipient's own macrophages. Recipient and donor (extrinsic) PAM were equivalent in their ability to phagocytize 1.7 μm and 3.9 μm latex microspheres in vivo and sensitized sheep red blood cells in vitro. Also, the extrinsic PAM appeared functionally equivalent to recipient PAM with respect to ability to translocate into interstitial tissue and migrate to the lung-associated lymph nodes (LALN). The recipient PAN appeared to phagocytize the extrinsic PAM, but the extrinsic PAM did not appear to phagocytize the recipient PAM. This could represent a different degree of physiological coordination of intrinsic and extrinsic PAM activities in the lung. Overall, results indicated that extrinsic PAM can live and function in the lungs of recipient rats, and perform most or all of the functions ascribed to recipient PAM. Results also support the hypothesis that PAM are able to move into the pulmonary interstitium and translocate to the LALM without the involvement of other pulmonary macrophages. (author)

Due to their unique physicochemical properties, the potential health effects of single-walled carbon nanotubes (SWCNTs) have attracted continuous attention together with their extensive application. In this study, we aimed to identify local and systemic health effects following pulmonary persistence of SWCNTs. As expected, SWCNTs remained in the lung for 13 weeks after a single intratracheal instillation (50, 100, and 200 μg/kg). In the lung, the total number of cells and the percentages of lymphocytes and neutrophils significantly increased at 200 μg/kg compared to the control, and the Th1-polarized immune response was induced accompanying enhanced expression of tissue damage-related genes and increased release of chemokines. Additionally, SWCNTs enhanced the expression of antigen presentation-related proteins on the surface of antigen-presenting cells, however, maturation of dendritic cells was inhibited by their persistence. As compared to the control, a significant increase in the percentage of neutrophils and a remarkable decrease of BUN and potassium level were observed in the blood of mice treated with the highest dose. This was accompanied by the down-regulation of the expression of antigen presentation-related proteins on splenocytes. Moreover, protein and glucose metabolism were disturbed with an up-regulation of fatty acid β-oxidation. Taken together, we conclude that SWCNTs may induce adverse health effects by disturbing immune and metabolic regulation functions in the body. Therefore, careful application of SWCNTs is necessary for the enforcement of safety in nano-industries. - Highlights: • We evaluated local and systemic health effects following persistence of SWCNTs. • SWCNTs remained in the lung for 13 weeks after a single intratracheal instillation. • Th1-polarized immune response was induced in the lung. • The expression of antigen presentation-related proteins was altered. • Immune and metabolic regulation function were disturbed.

Full Text Available We present a case of subglottic stenosis associated with benign thyroid tissue involvement due to relapse of multinodular goiter despite surgery 14 years ago.The patient had undergone bilateral subtotal thyroidectomy 14 years ago and the pathology report had been multinodular thyroid tissue at the time. The patient recently presented to an emergency service due to sudden development of respiratory distress and was then directed to our center. Cervical tomography showed bilateral thyroid tissue that narrowed the tracheal diameter by 80% by invading the trachea from the left wall at the level of the thyroid gland. The patient required urgent tracheostomy due to serious respiratory trouble. The trachea was incised vertically about 2.5 cm below the cricoid cartilage. A 2 cm endotracheal lesion with margins that could not be distinguished from the left vocal cord was observed and biopsies were taken from both this lesion and the tissue surrounding the trachea. A Montgomery T-tube extending from the subglottic area to the distal section was placed. Pathology evaluation revealed histopathological findings that matched normal thyroid tissue. Although infrequent, tracheal invasion associated with a thyroid cancer is known to occur. We present a case with postoperative intratracheal relapse due to a benign cause and the emergency treatment.

Acute respiratory distress syndrome (ARDS) is a devastating pulmonary condition in the critically ill patient. A therapeutic intervention is yet to be found that can prevent progression to ARDS. We recently demonstrated that the interaction between podoplanin expressed on inflammatory alveolar macrophages (iAMs) and its endogenous ligand, platelet C-type lectin-like 2 (CLEC-2), protects against exaggerated lung inflammation during a mouse model of ARDS. In this study, we aim to investigate the therapeutic use of a crosslinking/activating anti-podoplanin antibody (α-PDPN, clone 8.1.1) during lipopolysaccharide (LPS)-induced lung inflammation in mice. Intravenous administration of α-PDPN was performed 6 hours after intratracheal LPS in wildtype, C57Bl/6 mice. Lung function decline was measured by pulse oximetry as well as markers of local inflammation including bronchoalveolar lavage neutrophilia and cytokine/chemokine expression. In parallel, alveolar macrophages were isolated and cultured in vitro from haematopoietic-specific podoplanin-deficient mice (Pdpn fl/fl VAV1cre + ) and floxed-only controls treated with or without LPS in the presence or absence of α-PDPN. Lung function decline as well as alveolar neutrophil recruitment was significantly decreased in mice treated with the crosslinking/activating α-PDPN in vivo. Furthermore, we demonstrate that, in vitro, activation of podoplanin on iAMs regulates their secretion of proinflammatory cytokines and chemokines. These data confirm the importance of the CLEC-2-podoplanin pathway during intratracheal (IT)-LPS and demonstrate the beneficial effect of targeting podoplanin during IT-LPS in mice possibly via modulation of local cytokine/chemokine expression. Moreover, these data suggest that podoplanin-targeted therapies may have a beneficial effect in patients at risk of developing ARDS.

PolyPEG star polymers have potential utility as cost-effective polymeric drug delivery vehicles, and as such, it is important to develop an understanding of their biopharmaceutical behavior. Moreover, although a number of studies have evaluated the utility of PolyPEG stars in vitro, investigation of these novel materials in vivo has been limited. Herein, we evaluated the pharmacokinetics of a 64 kDa tritiated PEG-based star polymer after subcutaneous and pulmonary administration in rats. After subcutaneous administration, the star polymer showed near complete bioavailability (∼80%) and a similar organ biodistribution profile to the polymer after intravenous administration. After intratracheal instillation to the lungs, the star polymer showed limited bioavailability (∼3%), and most of the administered radiolabel was recovered in lung tissue and feces after 6 d. The data reported here suggest that star polymers display similar pharmaceutical behavior to PEGylated dendrimers after subcutaneous and inhaled delivery and may therefore be used as similar, but more cost-effective drug delivery vehicles.

Labeled lead ( 210 Pb) nitrate was administered once to male, mature guinea pigs by three routes of i.v. (intravenous injection), intratracheal and oral admin. (administration). Uptake of 210 Pb by whole blood (dose %) reached its peak one day after administration in the case of i.v. and intratracheal admin., the peak value being 5.0% and 3.4% respectively. On the 5th day, the uptake reduced to about 1/5 of the initial dose and the decrease was rapid thereafter. In the case of oral admin. the uptake on the first day was low at 0.19%, kept increasing until the 15th day after administration and decreased thereafter. In any mode of administration the uptake by the bone system of 210 Pb showed a high value from the beginning, and a tendency to accumulate was found thereafter. In any mode of administration the uptake by the liver of 210 Pb was high initially, but then started to decrease rather rapidly. As to the skin and hair, the uptake ratio was low but an appreciable uptake of 210 Pb was noted in terms of dose %, while uptake of 210 Pb was invariably low in the soft tissues investigated except for the spleen in which 210 Pb uptake ratio was relatively high in any mode of administration, this being a lasting tendency. The excretion of 210 Pb in every mode of administration was shown as total of exponential functions. Total excretion of 210 Pb in 30 days was, in the case of i.v., 19.4% into urine and 37.4% into feces, in the case of intratracheal admin., 22.0% into urine and 58.1% into feces and in the case of oral admin., 7.1% into urine and 77.0% into feces. Accumulation in the body of 210 Pb 30 days after admin., namely i.v., intratracheal and oral admin., were 42.9%, 20.2% and 15.1% respectively. The highest was the uptake by the bone system. (author)

The broad potential applications of manufactured nanomaterials call for urgent assessment of their environmental and biological safety. However, most of the previous work focused on the cell level performance; little was known about the consequences of nanomaterial exposure at the whole-body and organ levels. In the present paper, the radiotracer technique was employed to study the pulmonary deposition and the translocation to secondary target organs after ceria nanoparticles (nano-ceria) were intratracheally instilled into Wistar rats. It was found that 63.9 ± 8.2% of the instilled nano-ceria remained in the lung by 28 d postexposure and the elimination half-life was 103 d. At the end of the test period, only 1/8-1/3 of the daily elimination of nano-ceria from the lung was cleared via the gastrointestinal tract, suggesting that phagocytosis by alveolar macrophages (AMs) with subsequent removal towards the larynx was no longer the predominant route for the elimination of nano-ceria from the lung. The whole-body redistribution of nano-ceria demonstrated that the deposited nano-ceria could penetrate through the alveolar wall into the systemic circulation and accumulate in the extrapulmonary organs. In vitro study suggested that nano-ceria would agglomerate and form sediments in the bronchoalveolar aqueous surrounding while binding to protein would be conducive to the redispersion of nano-ceria. The decrease in the size of agglomerates might enhance the penetration of nano-ceria into the systemic circulation. Our findings suggested that the effect of nanomaterial exposure, even at low concentration, should be assessed because of the potential lung and systemic cumulative toxicity of the nanomaterials.

Studies have indicated that pulmonary exposure to welding fumes can induce a series of adverse effects in the respiratory system, including infection, bronchitis, siderosis and decreased pulmonary function. Recent clinical and epidemiological studies have found that pulmonary exposure to welding fumes is also associated with a higher incidence of cardiovascular events. However, there is insufficient evidence to confirm a direct effect of welding fumes on the cardiovascular system. The present study investigated the effects of pulmonary exposure to welding fumes on the heart and the vascular system in rats. Two chemically distinct welding fumes generated from manual metal arc-hard surfacing (MMA-HS) and gas metal arc-mild steel (GMA-MS) welding were tested. Three groups of rats were instilled intratracheally with MMA-HS (2 mg/rat), GMA-MS (2 mg/rat) or saline as control once a week for seven weeks. On days 1 and 7 after the last treatment, basal cardiovascular function and the cardiovascular response to increasing doses of adrenoreceptor agonists were assessed. MMA-HS treatment reduced the basal levels of left ventricle end-systolic pressure and dP/dt(max) at 1 day post-treatment, and decreased dP/dt(min) in response to isoproterenol (ISO) at 7 days post-treatment. Unlike MMA-HS, GMA-MS only affected left ventricular end-diastolic pressure in response to ISO at 7 days post-treatment. Treatment with MMA-HS or GMA-MS did not alter heart rate and blood pressure. Our findings suggest that exposure to different welding fumes can induce different adverse effects on the cardiovascular system, and that cardiac contractility may be a sensitive indicator of cardiovascular dysfunction.

To develop a new prosthesis for treating tracheal stenosis and tracheobronchomalacia, we examined the usefulness of an intratracheal stent made of shape memory alloy (SMA), a titanium-nickel alloy composed of 50% of each metal. At its recovery temperature (37 degrees C), the SMA stent was designed to recall the memorized shape of a coil with a diameter of 5 or 6 mm and a length of 10 mm. For the present experiment, it was transformed to a smaller coil 3 mm in diameter at a low temperature (-50 degrees C) and then loaded into the prosthesis introducer tube. An experimental model of potentially fatal tracheomalacia was made surgically by cutting and fracturing the tracheal cartilages of rabbits and tracheal collapse was confirmed by rigid bronchoscope. The introducer tube with the SMA stent was inserted and then the prosthesis was advanced into the collapsed segment of the trachea using the stent pusher. The SMA stent warmed bo body temperature and recovered its memorized shape after 1-2 min. In 3 out of 8 rabbits, follow-up bronchoscopy performed at 6, 8, and 10 months after implantation revealed satisfactory patency of the SMA stent and the trachea. After follow-up, 3 animals were sacrificed for histological observation, which showed little proliferation of granulation tissue and no dislocation of the SMA stent from the malacic portion. The remaining 5 rabbits have been followed for 18-24 months and are doing well. We conclude that the SMA stent maintains good tracheal patency, causes little reaction in the tracheal wall, and is easy to handle. Thus, it shows the potential for clinical application.

Administration of {sup 14}C-Moli1901 (duramycin, 2622U90), a 19 amino acid polycyclic peptide by intratracheal instillation (approximately 100 {micro}g) into the left cranial lobe of the lung of beagle dogs resulted in retention of 64% of the dose in the left cranial lobe for up to 28 days. In this study, we used accelerator mass spectrometry (AMS) to quantify Moli901 following administration of only 0.045 {micro}Ci of {sup 14}C-Moli901 per dog. Limits of quantitation of AMS were 0.03 (urine) to 0.3 (feces) ng equiv. Moli1901/g. Whole blood and plasma concentrations of {sup 14}C were <5ng/ml at all times after the dose. Concentrations of {sup 14}C in whole blood and plasma declined over the first day after the dose and rose thereafter, with the rise in plasma concentrations lagging behind those in whole blood. During the first 3 days after the dose, plasma accounted for the majority of {sup 14}C in whole blood, but after that time, plasma accounted for only 25-30% of the {sup 14}C in whole blood. Tissue (left and right caudal lung lobe, liver, kidney, spleen, brain) and bile concentrations were low, always less than 0.25% the concentrations found in the left cranial lung lobe. Approximately 13% of the dose was eliminated in urine and feces in 28 days, with fecal elimination accounting for about 10% of the dose. The data presented here are consistent with that obtained in other species. Moli1901 is slowly absorbed and excreted from the lung, and it does not accumulate in other tissues. Moli1901 is currently in the clinic and has proven to be safe in single dose studies in human volunteers and cystic fibrosis patients by the inhalation route. No information on the disposition of the compound in humans is available. This study in dogs demonstrates the feasibility of obtaining that information using {sup 14}C-Moli1901 and AMS.

Full Text Available Abstract Background Immunoglobulin A is the most abundant isotype in secretions from mucosal surfaces of the gastrointestinal, respiratory and genitourinary tracts and in external secretions such as colostrum, breast milk, tears and saliva. The high concentration of human secretory IgA (hsIgA in human colostrum strongly suggests that it should play an important role in the passive immune protection against gastrointestinal and respiratory infections. Materials and methods Human secretory IgA was purified from colostrum. The reactivity of hsIgA against mycobacterial antigens and its protective capacity against mycobacterial infection was evaluated. Results The passive administration of hsIgA reduces the pneumonic area before challenge with M. tuberculosis. The intratracheal administration of M. tuberculosis preincubated with hsIgA to mice greatly reduced the bacterial load in the lungs and diminished lung tissue injury. Conclusions HsIgA purified from colostrum protects against M. tuberculosis infection in an experimental mouse model.

Nipah virus (NiV) is a paramyxovirus (genus Henipavirus) that emerged in the late 1990s in Malaysia and has since been identified as the cause of sporadic outbreaks of severe febrile disease in Bangladesh and India. NiV infection is frequently associated with severe respiratory or neurological disease in infected humans with transmission to humans through inhalation, contact or consumption of NiV contaminated foods. In the work presented here, the development of disease was investigated in the African Green Monkey (AGM) model following intratracheal (IT) and, for the first time, small-particle aerosol administration of NiV. This study utilized computed tomography (CT) and magnetic resonance imaging (MRI) to temporally assess disease progression. The host immune response and changes in immune cell populations over the course of disease were also evaluated. This study found that IT and small-particle administration of NiV caused similar disease progression, but that IT inoculation induced significant congestion in the lungs while disease following small-particle aerosol inoculation was largely confined to the lower respiratory tract. Quantitative assessment of changes in lung volume found up to a 45% loss in IT inoculated animals. None of the subjects in this study developed overt neurological disease, a finding that was supported by MRI analysis. The development of neutralizing antibodies was not apparent over the 8-10 day course of disease, but changes in cytokine response in all animals and activated CD8+ T cell numbers suggest the onset of cell-mediated immunity. These studies demonstrate that IT and small-particle aerosol infection with NiV in the AGM model leads to a severe respiratory disease devoid of neurological indications. This work also suggests that extending the disease course or minimizing the impact of the respiratory component is critical to developing a model that has a neurological component and more accurately reflects the human condition.

The kinetics of the resorbed from the lungs plutonium metabolism and the forms of its presence in the blood as well as the dynamics of its deposit in the organs of secondary deposition (liver, skeleton) were studied in experiment with female rats. It was shown (gel-filtration method) that plutonium is present in blood serum in various physico-chemical forms: bound with macroglobulin, γ-globulin and albumin-transferrin fractions of proteins and not bound with proteins; this or that form of plutonium may dominate in time (4 min-64 days)

In order to investigate the relationship between pulmonary inflammation and particle clearance of nanoparticles, and also their dose dependency, we performed an instillation study of well-dispersed TiO 2 nanoparticles and examined the pulmonary inflammations, the particle clearance rate and histopathological changes. Wistar rats were intratracheally administered 0.1 mg (0.33 mg/kg), 0.2 mg (0.66 mg/kg), 1 mg (3.3 mg/kg), and 3 mg (10 mg/kg) of well-dispersed TiO 2 nanoparticles (diameter of agglomerates: 25 nm), and the pulmonary inflammation response and the amount of TiO 2 in the lung were determined from 3 days up to 12 months sequentially after the instillation. There were no increases of total cell or neutrophil counts in bronchoalveolar lavage fluid (BALF) in the 0.1 and the 0.2 mg-administered groups. On the other hand, mild infiltration of neutrophils was observed in the 1 and 3 mg-administered groups. Histopathological findings showed infiltration of neutrophils in the 1 and 3 mg-administered groups. Of special note, a granulomatous lesion including a local accumulation of TiO 2 was observed in the bronchioli-alveolar space in the 3 mg-administered group. The biological half times of the TiO 2 in the lung were 4.2, 4.4, 6.7, and 10.8 months in the 0.1, 0.2, 1, and 3 mg-administered groups, respectively. Neutrophil infiltration was observed as the particle clearance was delayed, suggesting that an excessive dose of TiO 2 nanoparticles may induce pulmonary inflammation and clearance delay.

A 64-year-old woman underwent completion thyroidectomy with upper tracheal ring resection and right-sided neck dissection for papillary carcinoma of the thyroid infiltrating the trachea and was given I radioiodine treatment. Three years later, she presented with hemoptysis. On evaluation, she had increased serum thyroglobulin and negative iodine scan (TENIS). F-FDG PET/CT scan did not identify any site of disease. One year later, Ga-PSMA scan done revealed a moderate focal tracer-avid intratracheal soft tissue; biopsy revealed it to be metastatic papillary carcinoma of the thyroid. This case kindles the possibility of using Ga-PSMA PET/CT to reveal occult disease in cases of TENIS.

The aim of this study was to evaluate the lung toxicity of multi-wall carbon nanotubes (MWCNTs). The present work exposed MWCNTs into the rats in intratracheal instillation administration modes. We systematically studied the distribution of nanoparticles in vivo, target organs and time-effects of nanotoxicity, dose-effects of nanotoxicity, etc. These results indicate that under the conditions of this test, pulmonary exposures to MWCNTs in rats by intratracheal instillation produced a series of multiple lesions in a dose-dependent and time-dependent manner, evidence of a foreign tissue body reaction.

While nephrotoxicity of cadmium is well documented, very limited information exists on renal effects of exposure to cadmium-containing nanomaterials. In this work, "omics" methodologies have been used to assess the action of cadmium-containing silica nanoparticles (Cd-SiNPs) in the kidney of Sprague-Dawley rats exposed intratracheally. Groups of animals received a single dose of Cd-SiNPs (1 mg/rat), CdCl2 (400 μg/rat) or 0.1 ml saline (control). Renal gene expression was evaluated 7 and 30 days post exposure by DNA microarray technology using the Agilent Whole Rat Genome Microarray 4x44K. Gene modulating effects were observed in kidney at both time periods after treatment with Cd-SiNPs. The number of differentially expressed genes being 139 and 153 at the post exposure days 7 and 30, respectively. Renal gene expression changes were also observed in the kidney of CdCl2-treated rats with a total of 253 and 70 probes modulated at 7 and 30 days, respectively. Analysis of renal gene expression profiles at day 7 indicated in both Cd-SiNP and CdCl2 groups downregulation of several cluster genes linked to immune function, oxidative stress, and inflammation processes. Differing from day 7, the majority of cluster gene categories modified by nanoparticles in kidney 30 days after dosing were genes implicated in cell regulation and apoptosis. Modest renal gene expression changes were observed at day 30 in rats treated with CdCl2. These results indicate that kidney may be a susceptible target for subtle long-lasting molecular alterations produced by cadmium nanoparticles locally instilled in the lung.

performed before in a mouse model. When studying the potential of fetal gene therapy for genetic diseases such as CF, the mouse model is very useful as a first proof-of-concept because of the wide availability of different transgenic mouse strains, the well documented embryogenesis and fetal development, less stringent ethical regulations, short gestation and the large litter size. Different access routes have been described to target the fetal rodent lung, including intra-amniotic injection(10-12), (ultrasound-guided) intrapulmonary injection(13,14) and intravenous administration into the yolk sac vessels(15,16) or umbilical vein(17). Our novel surgical procedure enables researchers to inject the agent of choice directly into the fetal mouse trachea which allows for a more efficient delivery to the airways than existing techniques(18).

In Japan, many patients equipped with TMV are under medical treatment at home after 1990. These patients can't put out sputa in trachea, so that these patient's family members must suck these patient's intratracheal sputa all days. Mr Yamamoto and Mr Tokunaga, main researchers of this study, began the study on the automatic SS of itratracheal sputa from 1999. In first stage, They developed the intermittent SS in detaining the suction tube within tracheal cannula, monitering the intratracheal pressure, but this system takes the ventilation away from the patient. Hypoventilation caused by this SS may cause the serious accident in patient. Therefore, we remodel the SS from intermittent SS to rollerpomp-type SS continuing to suck the itratracheal sputa with low volume from 2004, and thereafter we made up the SS of piston pomp type-SS finally at 2007. We developed the tracheal cannula with double suction holes of inner and lower hole in the lower part of its cannula together with the suction machine. We think that the practical use of this automatic SS will bring these patients with TMV and their family members great benefits. We desire that the practical use of this SS will be realized as soon as possible.

Pregnant ewes have been widely used to test vaccines against Chlamydia abortus. However, this model entails many disadvantages such as high economic costs and long periods of pregnancy. The murine model is very useful for specific studies but cannot replace the natural host for the later stages of vaccine evaluation. Therefore, a non-pregnant model of the natural host might be useful for a vaccine trial to select the best vaccine candidates prior to use of the pregnant model. With this aim, two routes of infection were assessed in young non-pregnant sheep, namely, intranasal (IN) and intratracheal (IT). In addition, groups of non-vaccinated sheep and sheep immunised with an inactivated vaccine were established to investigate the suitability of the model for testing vaccines. After the experimental infection, isolation of the microorganism in several organs, with pathological and immunohistochemical analyses, antibody production assessment and investigation by PCR of the presence of chlamydia in the vagina or rectum were carried out. Experimental IT inoculation of C. abortus induced pneumonia in sheep during the first few days post-infection, confirming the suitability of the IT route for testing vaccines in the natural host. The course of infection and the resulting pathological signs were less severe in vaccinated sheep compared with non-vaccinated animals, demonstrating the success of vaccination. IN infection did not produce evident lesions or demonstrate the presence of chlamydial antigen in the lungs and cannot be considered an appropriate model for testing vaccines.

Several cases of interstitial lung disease have been diagnosed among workers at a nylon flock plant, but the etiologic agent for the disease outbreak was unknown. The results of a medical survey and industrial hygiene study indicated that the dust present in the plant may be responsible. Thus, airborne dust collected at the plant was examined for its inflammatory potential in rat lungs. The endpoints measured were: (1) breathing rates, (2) differential cell counts of bronchoalveolar lavage cells, (3) alveolar macrophage (AM) chemiluminescence, (4) albumin concentration and matrix metalloprotease activities in the acellular fluid from the initial bronchoalveolar lavage, and (5) pulmonary histopathology. In the first study, rats received a single dose of the airborne dust sample (10 mg/kg body weight) by intratracheal (IT) instillation. At 1 d post-IT, all inflammatory endpoints were significantly increased versus controls, but by 29 d post-IT they did not differ significantly from controls. Histopathology demonstrated mild to moderate, multifocal, suppurative pneumonia, usually centered around bronchioles, at 1 d post-IT. At 29 d post-IT, pulmonary inflammation was minimal to mild and characterized by alveolar histocytosis usually restricted to the immediate area of retained bire-fringent fibers. In subsequent experiments, airborne dust was extracted with water and the dust (washed airborne dust) and water extract (soluble fraction) were separated by centrifugation for further study. Nylon tow dust was prepared in the laboratory by milling uncut nylon strands (called tow) that had not been treated with the finish or dyes that are commonly used in the flock plants. Rats were administered a single dose of a dust sample (10 mg/kg body weight) or the soluble fraction (1.3 ml/kg body weight) by IT administration and the same endpoints were measured at 1 d post-IT. The dust samples caused significant increases in all of the inflammatory endpoints; however, the soluble

To study the acute and subacute pulmonary toxicity of colloidal silver nanoparticles (Ag-NPs), 0 or 100 ppm of Ag-NPs were instilled intratracheally in mice. Cellular and biochemical parameters in bronchoalveolar lavage fluid (BALF) and histological alterations were determined 1, 3, 7, 15, and 30 days after instillation. Ag-NPs induced moderate pulmonary inflammation and injury on BALF indices during the acute period; however, these changes gradually regressed in a time-dependent manner. Concomitant histopathological and laminin immunohistochemical findings generally correlated to BALF data. Superoxide dismutase and metallothionein expression occurred in particle-laden macrophages and alveolar epithelial cells, which correlated to lung lesions in mice treated with Ag-NPs. These findings suggest that instillation of Ag-NPs causes transient moderate acute lung inflammation and tissue damage. Oxidative stress may underlie the induction of injury to lung tissue. Moreover, the expression of metallothionein in tissues indicated the protective response to exposure to Ag-NPs.

Renal morphological parameters were determined in rats intratracheally instilled with model cadmium-containing silica nanoparticles (Cd-SiNPs, 1mg/rat), also exploring whether their potential modifications would be associated with toxicogenomic changes. Cd-SiNP effects, evaluated 7 and 30 days post-exposure, were assessed by (i) histopathology (Haematoxylin/Eosin Staining), (ii) characterization of apoptotic features by TUNEL staining. Data were compared with those obtained by CdCl 2 (400μg/rat), SiNPs (600μg/rat), 0.1 ml saline. Area-specific cell apoptosis was observed in all treatment groups: cortex and inner medulla were the most affected regions. Apoptotic changes were apparent at 7 days post-exposure in both areas, and were still observable in inner medulla 30 days after treatment. Increase in apoptotic frequency was more pronounced in Cd-SiNP-treated animals compared to either CdCl 2 or SiNPs. Histological findings showed comparable alterations in the renal glomerular (cortex) architecture occurring in all treatment groups at both time-points considered. The glomeruli appeared often collapsed, showing condensed, packed mesangial and endothelial cells. Oedematous haemorrhagic glomeruli were also observed in Cd-SiNPs-treated animals. Bare SiNPs caused morphological and apoptotic changes without modifying the renal gene expression profile. These findings support the concept that multiple assays and an integrated testing strategy should be recommended to characterize toxicological responses to nanoparticles in mammalian systems.

Intratracheal administration of 3 H-, 14 C-, 59 Fe- or 125 I-labelled Pasteurella multocida germs to mice resulted in a more or less differentiated, nuclidedependent distribution of radioactivity in blood, spleen, liver, lung, kidney, and gastrointestinal tract, and was comparable to that following subcutaneous application. The elimination of the antigen from the lungs and other organs could be characterised by an e function, after having reached a certain level of distribution. Some of the antigen was persistent in the lung not less than 14 days. Extremely high activity concentration and persistence was recordable, following the use of 59 Fe complete antigen. Phagocytosis of Pasteurella multocida germs through alveolar macrophages of the lung was secured by autoradiography. Most of the antigen seemed to be discharged from the lungs through the digestive tract. Antigen distribution recorded from immunized and non-immunized mice seemed to suggest that the fate of antigen applied was affected by the kind of immunization. No difference in antigen distribution between non-immunized and subcutaneously immunized animals were provable, following intratracheal antigen application, but is was clearly provable, following intratracheal immunization. Elimination of antigen from the lungs of intratracheally immunized animals was found to occur faster than it did from non-immunized animals. (author)

Categorization of nano-structured titanium dioxide according to physicochemical characteristics and pulmonary toxicity

Full Text Available A potentially useful means of predicting the pulmonary risk posed by new forms of nano-structured titanium dioxide (nano-TiO2 is to use the associations between the physicochemical properties and pulmonary toxicity of characterized forms of TiO2. In the present study, we conducted intratracheal administration studies in rats to clarify the associations between the physicochemical characteristics of seven characterized forms of TiO2 and their acute or subacute pulmonary inflammatory toxicity. Examination of the associations between the physicochemical characteristics of the TiO2 and the pulmonary inflammatory responses they induced revealed (1 that differences in the crystallinity or shape of the TiO2 particles were not associated with the acute pulmonary inflammatory response; (2 that particle size was associated with the acute pulmonary inflammatory response; and (3 that TiO2 particles coated with Al(OH3 induced a greater pulmonary inflammatory response than did non-coated particles. We separated the seven TiO2 into two groups: a group containing the six TiO2 with no surface coating and a group containing the one TiO2 with a surface coating. Intratracheal administration to rats of TiO2 from the first group (i.e., non-coated TiO2 induced only acute pulmonary inflammatory responses, and within this group, the acute pulmonary inflammatory response was equivalent when the particle size was the same, regardless of crystallinity or shape. In contrast, intratracheal administration to rats of the TiO2 from the second group (i.e., the coated TiO2 induced a more severe, subacute pulmonary inflammatory response compared with that produced by the non-coated TiO2. Since alteration of the pulmonary inflammatory response by surface treatment may depend on the coating material used, the pulmonary toxicities of coated TiO2 need to be further evaluated. Overall, the present results demonstrate that physicochemical properties may be useful for predicting the

Our purpose was to assess sustained delivery and enhanced efficacy of pirfenidone-loaded nanoparticles after intratracheal instillation. Poly(lactide-co-glycolide) nanoparticles containing pirfenidone (NPs) were prepared and characterized. Biodistribution of NPs and solution was assessed using LC-MS after intratracheal administration in C57Bl/6 mice at 3 and 24 h and 1 week post-administration. Efficacy was tested in C57Bl/6 mice in a bleomycin-induced pulmonary fibrosis model. Mice received 10 μg pirfenidone intratracheally in solution or NPs, once a week, for 3 weeks after bleomycin administration. Drug effects were monitored on day 28. Lung hydroxyproline content, total number of cells, and numbers of macrophages, lymphocytes, and neutrophils in bronchoalveolar lavage (BAL) were assessed. Numbers of macrophages, lymphocytes, and neutrophils were assessed in the lung as well. NPs sustained significantly higher levels of pirfenidone in the lungs and BAL at 24 h and 1 week, compared to the solution group. Pirfenidone solution and NPs significantly reduced hydroxyproline levels by 57 and 81%, respectively, compared to bleomycin alone. At the end of 4 weeks, BAL cellularity was reduced by 25.4% and 56% with solution and NP treatment, respectively. The numbers of lymphocytes and neutrophils in the BAL were also reduced by 58.9 and 82.4% for solution and 74.5% and 89.7% for NPs, respectively. The number of inflammatory macrophages in the lung was reduced by 62.8% and the number of neutrophils was reduced by 59.1% in the NP group and by 37.7% and 44.5%, respectively, in the solution group, compared to bleomycin alone. In conclusion, nanoparticles sustain lung pirfenidone delivery and enhance its anti-fibrotic efficacy.

Repeated intratracheal instillation of PM10 induces lipid reshaping in lung parenchyma and in extra-pulmonary tissues.

Directory of Open Access Journals (Sweden)

Angela Maria Rizzo

Full Text Available Adverse health effects of air pollution attributed mainly to airborne particulate matter have been well documented in the last couple of decades. Short term exposure, referring to a few hours exposure, to high ambient PM10 concentration is linked to increased hospitalization rates for cardiovascular events, typically 24 h after air pollution peaks. Particulate matter exposure is related to pulmonary and cardiovascular diseases, with increased oxidative stress and inflammatory status. Previously, we have demonstrated that repeated intratracheal instillation of PM10sum in BALB/c mice leads to respiratory tract inflammation, creating in lung a condition which could potentially evolve in a systemic toxic reaction. Additionally, plasma membrane and tissue lipids are easily affected by oxidative stress and directly correlated with inflammatory products. With this aim, in the present investigation using the same model, we analyzed the toxic potential of PM10sum exposure on lipid plasma membrane composition, lipid peroxidation and the mechanisms of cells protection in multiple organs such as lung, heart, liver and brain. Obtained results indicated that PM10 exposure led to lung lipid reshaping, in particular phospholipid and cholesterol content increases; concomitantly, the generation of oxidative stress caused lipid peroxidation. In liver we found significant changes in lipid content, mainly due to an increase of phosphatidylcholine, and in total fatty acid composition with a more pronounced level of docosahexaenoic acid; these changes were statistically correlated to lung molecular markers. Heart and brain were similarly affected; heart was significantly enriched in triglycerides in half of the PM10sum treated mice. These results demonstrated a direct involvement of PM10sum in affecting lipid metabolism and oxidative stress in peripheral tissues that might be related to the serious systemic air-pollution effects on human health.

The current study aimed to develop gold nanoparticles (GNPs) and liposome-embedded gold nanoparticles (LGNPs) as drug carriers for temozolomide (TMZ) and investigate the possible therapeutic effects of intratracheal inhalation of nanoformulation of TMZ-loaded gold nanoparticles (TGNPs) and liposome-embedded TGNPs (LTGNPs) against urethane-induced lung cancer in BALB/c mice. Physicochemical characters and zeta potential studies for gold nanoparticles (GNPs) and liposome-embedded gold nanoparticles (LGNPs) were performed. The current study was conducted by inducing lung cancer chemically via repeated exposure to urethane in BALB/C mice. GNPs and LGNPs were exhibited in uniform spherical shape with adequate dispersion stability. GNPs and LGNPs showed no significant changes in comparison to control group with high safety profile, while TGNPs and LTGNPs succeed to improve all biochemical data and histological patterns. GNPs and LGNPs are promising drug carriers and succeeded in the delivery of small and efficient dose of temozolomide in treatment lung cancer. Antitumor activity was pronounced in animal-treated LTGNPs, these effects may be due to synergistic effects resulted from combination of temozolomide and gold nanoparticles and liposomes that may improve the drug distribution and penetration.

Here we establish a time-series of lung inflammatory response to CBNPs. Female C57BL/6 mice were intratracheally...... to nine 8-h working days at the current Danish occupational exposure limit induced biphasic inflammatory response in gene expression that lasted until 42d post-exposure, raising concern over the chronic effects of CBNP exposure....... transcript levels were associated with immune-inflammatory response and acute phase response pathways, consistent with the BAL profiles and expression changes found in common respiratory infectious diseases. Genes involved in DNA repair, apoptosis, cell cycle regulation, and muscle contraction were also...... differentially expressed. Gene expression changes associated with inflammatory response followed a biphasic pattern, with initial changes at 3h post-exposure declining to base-levels by 3d, increasing again at 14d, and then persisting to 42d post-exposure.

Purpose: A dose and volume limiting factor in radiation treatment of thoracic cancer is the development of fibrosis in normal lung. The goal of the present study was to determine whether expression prior to irradiation of a transgene for human manganese superoxide dismutase (MnSOD) or human copper/zinc superoxide dismutase (Cu/ZnSOD) protects against irradiation-induced lung damage in mice. Methods and Materials: Athymic Nude (Nu/J) mice were intratracheally injected with 10 9 plaque-forming units (PFU) of a replication-incompetent mutant adenovirus construct containing the gene for either human MnSOD, human copper/zinc superoxide dismutase (Cu/ZnSOD) or LacZ. Four days later the mice were irradiated to the pulmonary cavity to doses of 850, 900, or 950 cGy. To demonstrate adenoviral infection, nested reverse transcriptase-polymerase chain reaction (RT-PCR) was carried out with primers specific for either human MnSOD or Cu/ZnSOD transgene on freshly explanted lung, trachea, or alveolar type II cells, and immunohistochemistry was used to measure LacZ expression. RNA was extracted on day 0, 1, 4, or 7 after 850 cGy of irradiation from lungs of mice that had previously received adenovirus or had no treatment. Slot blot analysis was performed to quantitate RNA expression for IL-1, tumor necrosis factor (TNF)-α, TGF-β, MnSOD, or Cu/ZnSOD. Lung tissue was explanted and tested for biochemical activity of MnSOD or Cu/ZnSOD after adenovirus injection. Other mice were sacrificed 132 days after irradiation, lungs excised, frozen in OCT, (polyvinyl alcohol, polyethylene glycol mixture) sectioned, H and E stained, and evaluated for percent of the lung demonstrating organizing alveolitis. Results: Mice injected intratracheally with adenovirus containing the gene for human MnSOD had significantly reduced chronic lung irradiation damage following 950 cGy, compared to control mice or mice injected with adenovirus containing the gene for human Cu/ZnSOD or LacZ.

Studies on the lung retention of polycyclic aromatic hydrocarbons (PAH) after inhalation have indicated that, in general, the PAH are rapidly cleared from the respiratory tract. Clearance of the PAH from the lungs is best described as bi-phasic, with the long-term component of the clearance curve having a half-time of greater than 24 h. The purpose of this study was to determine whether a relationship exists between the lipophilicity (as measured by the octanol/water partition coefficient, P) of various PAH and the short-term and long-term clearance half-times of PAH in rat lungs. Female F344/Crl rats were administered intratracheally 1 nmol of 14 C-labelled anthracene (AN), benz (a) anthracene (BA), 1-nitropyrene (NP), 6-nitrobenzo (a) pyrene (6-NBP), or dibenzo (c, g) carbazole (DBC). At various times after instillation rats were sacrificed and the amount of 14 C from rat lungs following instillation of the different PAH was biphasic. In all cases, greater than 85% of the initial dose instilled was cleared with a half-time of less than 1 h. The half-times for clearance of the residual 14 C (1-15% of the dose) were 26, 30, 36, 53 and 63 h for AN, NP, 6-NBP, BA and DCB, respectively. The log of the octanol-water partition coefficients for the different PAH examined ranged from 4.1 (AN) to 6.05 (DBC). Plots of the octanol/water coefficients vs. the long-term clearance half-time for the PAH indicated a linear correlation (p 2 =0.96). The results from this study indicate that the greater the lipophilicity of the PAH, the slower the long-term clearance of a small fraction (1-15%) of PAH from rat lungs. These data suggest that predictions of long-term lung clearance can be made for PAH with log octanol-water partition coefficients between 4 and 6. (author)

Therapeutic natural products and medicinal herbs has gained popularity. The anti-antigenic action of the plant alkaloid nordihydroguaiaretic acid (NDGA) was studied in ovalbumin (OA)-sensitized guinea pigs. In one series of experiments conscious, non-sedated guinea pigs were challenged with OA aerosol. Specific airway resistance (SR AW ) was monitored using a two-chambered whole-body plethysmograph. OA aerosol increased SR AW above that produced by vehicle administration. Prior NDGA administration by a 1min 0.9% aerosol (w/vol) attenuated the increase in SR AW resulting from OA challenge. In the anesthetized guinea pig pretreated with indomethacin, pyrilamine and propranolol, intravenous OA injection increased intra-tracheal pressure above vehicle injection. Intravenous NDGA administration (5mg/kg) reduced the intra-tracheal pressure increases. In a third series of experiments plasma leukotriene C 4 was measured by radio-immunoassay in 3 groups challenged with OA aerosol: vehicle-treated OA-sensitized, OA-sensitized receiving NDGA and vehicle treated guinea pigs. NDGA pretreatment reduced plasma LTC 4 in response to OA challenge in OA sensitized guinea pigs. This study demonstrates that NDGA is an effective antigenic agent when given by aerosol or intravenous injection in either conscious or anesthetized guinea pigs, respectively. The mechanism of action of NDGA is presumed primarily be due to the blockage of 5-lipoxygenase and therefore the synthesis of leukotrienes. Copyright © 2016 Elsevier B.V. All rights reserved.

Chrysotile (CH), the most common form of asbestos, is rendered less toxic by heating it at 1000 o C and converting it to forsterite (FO-1000). However, further safety tests are needed to evaluate human health risk of these materials. It has been reported that serum concentrations of megakaryocyte potentiating factor N-ERC/mesothelin become elevated in patients with mesotheliomas caused by asbestos exposure. In this study, a single 2 mg dose of CH or FO-1000 was intratracheally administered to rats. Within 180 days after the administrations, serum N-ERC/mesothelin concentrations, levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG) in lung tissues and pathological changes in respiratory organs were determined. In the CH group, a significant increase in serum N-ERC/mesothelin concentrations was observed immediately after intratracheal administration, and the elevation lasted for 30 days. In lung tissues, positive staining for 8-OHdG in bronchioles, alveolar epithelium, inflammatory cells, and granulomas was evidence of a marked DNA oxidative damage. Furthermore, measurements of 8-OHdG in lung tissues based on the HPLC-ECD method suggested that serum N-ERC/mesothelin concentrations tended to increase when there are significant DNA damages in lung tissues. In contrast, in the FO-1000 group, a marked rise in serum N-ERC/mesothelin concentrations occurred only in the early phase (1-7 days) after intratracheal administration. Similarly, FO-1000 induced elevation of 8-OHdG in lung tissues was transient and modest compared with those of the CH-treated animals. In both the CH and FO-1000 groups, we observed significant correlations between serum N-ERC/mesothelin concentrations and lung 8-OHdG concentrations (r = 0.559, p = 0.001 for the CH group; r = 0.516, p = 0.01 for the FO-1000 group). In summary, we demonstrated the possibility of using serum N-ERC/mesothelin concentrations as a useful biomarker for early phase exposure to either CH or FO-1000.

Recent studies have reported the development of lung toxicity after pulmonary exposure to CeO2 NPs. However, little is known about the possible thrombotic effects of these NPs. The present study investigated the acute (24 hours effect of intratracheal (IT instillation of either CeO2 NPs (0.1 or 0.5 mg/kg or saline (control on pulmonary and systemic inflammation and oxidative stress and thrombosis in mice. CeO2 NPs induced a significant increase of neutrophils into the bronchoalveolar lavage (BAL fluid with an elevation of tumor necrosis factor α (TNFα and a decrease in the activity of the antioxidant catalase. Lung sections of mice exposed to CeO2 NPs showed a dose-dependent infiltration of inflammatory cells consisting of macrophages and neutrophils. Similarly, the plasma levels of C-reactive protein and TNFα were significantly increased, whereas the activities of catalase and total antioxidant were significantly decreased. Interestingly, CeO2 NPs significantly and dose dependently induced a shortening of the thrombotic occlusion time in pial arterioles and venules. Moreover, the plasma concentrations of fibrinogen and plasminogen activator inhibitor-1 were significantly elevated by CeO2 NPs. The direct addition of CeO2 NPs (1, 5, or 25 µg/mL to mouse whole blood, collected from the inferior vena cava, in vitro neither caused significant platelet aggregation nor affected prothrombin time or partial

Middle East Respiratory Syndrome Coronavirus (MERS-CoV) continues to be a threat to human health in the Middle East. Development of countermeasures is ongoing; however, an animal model that faithfully recapitulates human disease has yet to be defined. A recent study indicated that inoculation of common marmosets resulted in inconsistent lethality. Based on these data we sought to compare two isolates of MERS-CoV. We followed disease progression in common marmosets after intratracheal exposure with: MERS-CoV-EMC/2012, MERS-CoV-Jordan-n3/2012, media, or inactivated virus. Our data suggest that common marmosets developed a mild to moderate non-lethal respiratory disease, which was quantifiable by computed tomography (CT), with limited other clinical signs. Based on CT data, clinical data, and virological data, MERS-CoV inoculation of common marmosets results in mild to moderate clinical signs of disease that are likely due to manipulations of the marmoset rather than as a result of robust viral replication. - Highlights: • Common marmosets infected with MERS-EMC and MERS-JOR did not develop lethal disease. • Infected subjects developed transient signs of clinical disease. • CT indicated few differences between the infected and control groups. • Marmosets do not faithfully replicate human MERS pathogenesis.

Clearance kinetics and matrix binding partners of the receptor for advanced glycation end products.

Directory of Open Access Journals (Sweden)

Pavle S Milutinovic

Full Text Available Elucidating the sites and mechanisms of sRAGE action in the healthy state is vital to better understand the biological importance of the receptor for advanced glycation end products (RAGE. Previous studies in animal models of disease have demonstrated that exogenous sRAGE has an anti-inflammatory effect, which has been reasoned to arise from sequestration of pro-inflammatory ligands away from membrane-bound RAGE isoforms. We show here that sRAGE exhibits in vitro binding with high affinity and reversibly to extracellular matrix components collagen I, collagen IV, and laminin. Soluble RAGE administered intratracheally, intravenously, or intraperitoneally, does not distribute in a specific fashion to any healthy mouse tissue, suggesting against the existence of accessible sRAGE sinks and receptors in the healthy mouse. Intratracheal administration is the only effective means of delivering exogenous sRAGE to the lung, the organ in which RAGE is most highly expressed; clearance of sRAGE from lung does not differ appreciably from that of albumin.

Since the most likely route of exposure to nickel in the workplace is via the respiratory tract, the objectives of the experiments described here were to determine the retention pattern of Ni in the lungs, identify the target organs for Ni absorbed from the respiratory tract, and determine rates for excretion of Ni. Male and female F344 rats were given 17, 190, or 1800 nmoles Ni (as a nickel sulfate solution) in saline, containing trace amounts of 63 Ni, by intratracheal instillation. Urine and feces were collected, and rats were necropsied at predetermined times up to 96 hr after instillation. At all times, lungs, trachea, larynx, kidney, and urinary bladder contained the highest concentrations of Ni as determined by liquid scintillation spectrometry. Urine was the major route for excretion of Ni, accounting for 50% of the dose after instillation of 17 or 190 nmoles Ni, and 80% of the dose after instillation of 1800 nmoles Ni. The half-time for urinary excretion of Ni increased from 4.6 hr at the highest dose to 23 hr at the lowest dose used. Fecal excretion accounted for 30% (17- and 190-nmole doses) or 13% (1800 nmoles) of the initial dose. Of the Ni remaining in the body at the end of 96 hr, over 50% was in the lungs. The long-term half-time for clearance of Ni from the lungs ranged from 21 hr at the highest dose to 36 hr at the lowest dose instilled. As the amount of instilled Ni decreased, the fraction of the instilled Ni associated with the long-term clearance component increased (from 24% at the highest dose to 40% at the lowest dose). Results suggest that, over the range of doses studied, both pulmonary clearance of Ni and routes for excretion of Ni were dependent on the instilled dose

Full Text Available An administrative contract is the will between a public authority either a person empowe¬red by it, and one or more natural or legal persons, whether private or public, pursuing the realization of a public interest and to which a special scheme of administrative law applies. The typology of administrative contracts is very varied, depending on the evolution of the society’s needs. Thus, they are currently included in the category of administrative contracts: concession contracts and public procurement contracts, contracts for the use of public goods, public management contracts, public-private partnership contracts, public lending contracts and constitutive documents of the associative structures of public authorities.

Full Text Available Abstract Rationale Several epidemiological studies associated exposure to increased levels of particulate matter in Augsburg, Germany with cardiovascular mortality and morbidity. To elucidate the mechanisms of cardiovascular impairments we investigated the cardiopulmonary responses in spontaneously hypertensive rats (SHR, a model for human cardiovascular diseases, following intratracheal instillation of dust samples from Augsburg. Methods 250 μg, 500 μg and 1000 μg of fine ambient particles (aerodynamic diameter 2.5-AB collected from an urban background site in Augsburg during September and October 2006 (PM2.5 18.2 μg/m3, 10,802 particles/cm3 were instilled in 12 months old SHRs to assess the inflammatory response in bronchoalveolar lavage fluid (BALF, blood, lung and heart tissues 1 and 3 days post instillation. Radio-telemetric analysis was performed to investigate the cardiovascular responses following instillation of particles at the highest dosage based on the inflammatory response observed. Results Exposure to 1000 μg of PM2.5-AB was associated with a delayed increase in delta mean blood pressure (ΔmBP during 2nd-4th day after instillation (10.0 ± 4.0 vs. -3.9 ± 2.6 mmHg and reduced heart rate (HR on the 3rd day post instillation (325.1 ± 8.8 vs. 348.9 ± 12.5 bpm. BALF cell differential and inflammatory markers (osteopontin, interleukin-6, C-reactive protein, and macrophage inflammatory protein-2 from pulmonary and systemic level were significantly induced, mostly in a dose-dependent way. Protein analysis of various markers indicate that PM2.5-AB instillation results in an activation of endothelin system (endothelin1, renin-angiotensin system (angiotensin converting enzyme and also coagulation system (tissue factor, plasminogen activator inhibitor-1 in pulmonary and cardiac tissues during the same time period when alternation in ΔmBP and HR have been detected. Conclusions Our data suggests that high concentrations of PM2.5-AB

Pressure control ventilation (PCV), high-frequency oscillation (HFO), and intratracheal pulmonary ventilation (ITPV) may all be used to provide lung protective ventilation in acute respiratory distress syndrome, but the specific approach that is optimal remains controversial. Saline lavage was used to produce acute respiratory distress syndrome in 21 sheep randomly assigned to receive PCV, HFO, or ITPV as follows: positive end-expiratory pressure (PCV and ITPV) and mean airway pressure (HFO) were set in a pressure-decreasing manner after lung recruitment that achieved a ratio of Pao2/Fio2 > 400 mmHg. Respiratory rates were 30 breaths/min, 120 breaths/min, and 8 Hz, respectively, for PCV, ITPV, and HFO. Eucapnia was targeted with peak carinal pressure of no more than 35 cm H2O. Animals were then ventilated for 4 h. There were no differences among groups in gas exchange, lung mechanics, or hemodynamics. Tidal volume (PCV, 8.9 +/- 2.1 ml/kg; ITPV, 2.7 +/- 0.8 ml/kg; HFO, approximately 2.0 ml/kg) and peak carinal pressure (PCV, 30.6 +/- 2.6 cm H2O; ITPV, 22.3 +/- 4.8 cm H2O; HFO, approximately 24.3 cm H2O) were higher in PCV. Pilot histologic data showed greater interstitial hemorrhage and alveolar septal expansion in PCV than in HFO or ITPV. These data indicate that HFO, ITPV, and PCV when applied with an open-lung protective ventilatory strategy results in the same gas exchange, lung mechanics, and hemodynamic response, but pilot data indicate that lung injury may be greater with PCV.

To understand the effect of thuringiensin on the lungs tissues, male Sprague-Dawley rats were administrated with thuringiensin by intratracheal instillation at doses 0.8, 1.6 and 3.2 mg/kg of body weight, respectively. The rats were sacrificed 4 h after treatment, and lungs were isolated and examined. Subsequently, an effective dose of 1.6 mg/kg was selected for the time course study (4, 8, 12, and 24 h). Intratracheal instillation of thuringiensin resulted in lung damage, as evidenced by increase in lung weight and decrease in alkaline phosphatase (10-54%), an enzyme localized primarily in pulmonary alveolar type II epithelial cells. Furthermore, the administration of thuringiensin caused increases in lipid peroxidation (21-105%), the indices of lung injury. In addition, the superoxide dismutase (SOD) and glutathione (GSH) activities of lung tissue extracts were measured to evaluate the effect of thuringiensin on antioxidant defense system. The SOD activity and GSH content in lung showed significant decreases in a dose-related manner with 11-21% and 15-37%, respectively. Those were further supported by the release of proinflammatory cytokines, as indicated by increases in IL-1β (229-1017%) and TNF-α (234%) levels. Therefore, the results demonstrated that changes in the pulmonary oxidative-antioxidative status might play an important role in the thuringiensin-induced lung injury

Several studies have reported biological effects of Mikania glomerata and Mikania laevigata, used in Brazilian folk medicine for respiratory diseases. Pneumoconiosis is characterized by pulmonary inflammation caused by coal dust exposure. In this work, we evaluated the effect of pretreatment with M. glomerata and M. laevigata extracts (MGE and MLE, respectively) (100 mg/kg, s.c.) on inflammatory and oxidative stress parameters in lung of rats subjected to a single coal dust intratracheal instillation. Rats were pretreated for 2 weeks with saline solution, MGE, or MLE. On day 15, the animals were anesthetized, and gross mineral coal dust or saline solutions were administered directly in the lung by intratracheal instillation. Fifteen days after coal dust instillation, the animals were killed. Bronchoalveolar lavage (BAL) was obtained; total cell count and lactate dehydrogenase (LDH) activity were determined. In the lung, myeloperoxidase activity, thiobarbituric acid-reactive substances (TBARS) level, and protein carbonyl and sulfhydryl contents were evaluated. In BAL of treated animals, we verified an increased total cell count and LDH activity. MGE and MLE prevented the increase in cell count, but only MLE prevented the increase in LDH. Myeloperoxidase and TBARS levels were not affected, protein carbonylation was increased, and the protein thiol levels were decreased by acute coal dust intratracheal administration. The findings also suggest that both extracts present an important protective effect on the oxidation of thiol groups. Moreover, pretreatment with MGE and MLE also diminished lung inflammatory infiltration induced by coal dust, as assessed by histopathologic analyses.

We examined the biological effects of the nickel oxide (NiO) nanoparticles by inhalation and instillation study. Wistar male rats were exposed to NiO nanoparticles (nNiOs) for 4 weeks (6 hrs/day). The nNiOs was black-colored NiO (99.8%) and average particle size (APS) was 20 nm. The geometric mean diameter of the particles in the chamber and the daily average exposure concentration were 139 ± 12 nm and 1.0 ± 0.5 x 105 particles/cc, respectively. The deposited amount of nNiOs in the rat lungs at 4 days after the inhalation exposure ended was 29 ± 4 μg. Although nNiOs exposure group showed temporal significant increase in the number of total cells in brochoalveolar lavage fluid (BALF) at 4 days after the exposure end, the difference were not seen at one month after an exposure end compared with control group. The histopathological change was not severe just after the inhalation nor throughout the observation time. Elemental mappings of nickel showed that nickel particles were located in agglomeration at the pulmonary macrophages.

MOTIVATION OF ADMINISTRATIVE ACTS – GUARANTEE OF GOOD ADMINISTRATION

Directory of Open Access Journals (Sweden)

Adelin Mihai ZĂGĂRIN

2018-05-01

Full Text Available The present article deals with the aspects of motivating administrative acts, both doctrinaire and practical, of jurisprudence. The duty of the administration to motivate its decisions is submitted in the Charter of Fundamental Rights of the European Union, art. 41. In the current European legal order, the rationale for administrative acts is considered and refers to one of the most important conditions of validity of the administrative act. The Romanian Constitution ensures and emphasizes the motivation, as it is imposed by the Charter. The realization of this fundamental right to motivate administrative acts is possible by calling upon a set of values from the administration, such as transparency, professionalism and the imposition of high quality standards. Motivation is achieved where we have a good administration, and whether citizens are, among other things, respected fundamental rights and freedoms, access to information is guaranteed and motivated their decisions. Although administrative normative acts are motivated by the administration, examples that show that individual ones are unmotivated or incompletely motivated are enough, which made the various employers legally answer for the non-motivation of their decisions to terminate work relationships with several of the employees. The motivation of administrative acts is necessary, mandatory and must be done with rigor. It is highlighted that inadequate, incomplete or vicious reasoning may result in suspension or even annulment of the administrative act by the court.

Sampling of complex mixtures of airborne contaminants for chronic animal toxicity tests often involves numerous sampling devices, requires extensive sampling time, and yields forms of collected materials unsuitable for administration to animals. A method is described which used a high volume, wet venturi scrubber for collection of respirable fractions of emissions from iron foundry casting operations. The construction and operation of the sampler are presented along with collection efficiency data and its application to the preparation of large quantities of samples to be administered to animals by intratracheal instillation.

As various quartz polymorphs react differently in lungs, a differentiation of effects is needed while setting occupational exposure levels. The objective of this European Collective Research Project SILICERAM was to characterize differences in biological activity of four quartz species, i.) 2 quartz-containing materials collected at typical ceramic manufacturing sites (Tableware granulate, TG and Tableware cast, TC) versus ii.) a designed ceramic dust sample (Contrived Sample, CS) and iii.) ground quartz DQ12 (well-characterised standard quartz (Positive Control, PC) and TiO{sub 2} (negative control). TG and TC had been selected as the most promising two candidates based on a preceding in vitro screening of 5 factory samples. Total doses of 5 mg per rat of the TG and TC, 1.1 mg of the CS and 0.33 mg of the PC corresponding to 0.29, 0.16, 0.29 and 0.29 mg quartz per rat, respectively, were administered to rats by intratracheal instillation. After 3 days, bronchoalveolar lavagate (BAL) analysis resulted in polymorphonuclear neutrophil (PMN) levels of 15%, 25%, 0.6% and 25% in the TG, TC, CS and PC groups, respectively. At 28 days, the values were 29%, 20%, 7% and 45%. Histopathologically, the TG and TC groups showed very slight to slight effects, the PC group, however, stronger effects after the same period. In conclusion, the following ranking was found: PC > TG > TC > CS > TiO{sub 2} > Vehicle Control. Thus, a clear differentiation of effects for TG and TC, CS and PC was found. From a regulatory point of view, the substance-specific toxic potentials of TG and TC may need to be considered when devising occupational exposure limits.

Hopes and wishes were rising when he was elected as the president of Indonesia. This paper will describe various innovations undertaken before and after his presidential inauguration as well as the assorted innovations made in reforming the administration of his cabinet. As the president of Indonesia, Joko Widodo is required to realize the aspirations of the people in freeing the government from corruption, collusion, and nepotism. The management of ministerial and non-ministerial institutions becomes the very first crucial issue undertaken by Joko Widodo. This led to a polemic in regards to reducing or increasing the number of institutions, as the Jokowi administration actually increased the amount. In Susilo Bambang Yudhoyono's administration, several policies were made systematically and based on legislations that had been approved by the lagislature. Joko Widodo's administration in more partial in nature. The administrative reform program that is highly anticipated is the continuation of the Public Service Act. This law is a step forward from the administrative reform program that aims at the creation of good governance. Changes is career path, salary system, pension and benefits for civil servants, performance-based staffing are various efforts of sustainability carried out by Joko Widodo's administration.

Semantic Modeling of Administrative Procedures from a Spanish Regional Public Administration

Directory of Open Access Journals (Sweden)

Francisco José Hidalgo López

2018-02-01

Full Text Available Over the past few years, Public Administrations have been providing systems for procedures and files electronic processing to ensure compliance with regulations and provide public services to citizens. Although each administration provides similar services to their citizens, these systems usually differ from the internal information management point of view since they usually come from different products and manufacturers. The common framework that regulations demand, and that Public Administrations must respect when processing electronic files, provides a unique opportunity for the development of intelligent agents in the field of administrative processes. However, for this development to be truly effective and applicable to the public sector, it is necessary to have a common representation model for these administrative processes. Although a lot of work has already been done in the development of public information reuse initiatives and common vocabularies standardization, this has not been carried out at the processes level. In this paper, we propose a semantic representation model of both processes models and processes for Public Administrations: the procedures and administrative files. The goal is to improve public administration open data initiatives and help to develop their sustainability policies, such as improving decision-making procedures and administrative management sustainability. As a case study, we modelled public administrative processes and files in collaboration with a Regional Public Administration in Spain, the Principality of Asturias, which enabled access to its information systems, helping the evaluation of our approach.

A Logic for Inclusion of Administrative Domains and Administrators in Multi-domain Authorization

Science.gov (United States)

Iranmanesh, Zeinab; Amini, Morteza; Jalili, Rasool

Authorization policies for an administrative domain or a composition of multiple domains in multi-domain environments are determined by either one administrator or multiple administrators' cooperation. Several logic-based models for multi-domain environments' authorization have been proposed; however, they have not considered administrators and administrative domains in policies' representation. In this paper, we propose the syntax, proof theory, and semantics of a logic for multi-domain authorization policies including administrators and administrative domains. Considering administrators in policies provides the possibility of presenting composite administration having applicability in many collaborative applications. Indeed, administrators and administrative domains stated in policies can be used in authorization. The presented logic is based on modal logic and utilizes two calculi named the calculus of administrative domains and the calculus of administrators. It is also proved that the logic is sound. A case study is presented signifying the logic application in practical projects.

Case of administrative dispute

Directory of Open Access Journals (Sweden)

Xhemazie Ibraimi

2015-11-01

Full Text Available The activity of administrative bodies includes big numbers of various acts and actions, through which the will of public administration is formed. The will of public administration bodies, expressed in administrative individual and normative acts, in administrative contracts and real acts, finds its reflection in the Constitution, laws and other provisions of legal character. All this activity is not inerrant and therefore, it is not uncontrollable. The supervision of executive activity is subject to political control of administrative acts through authorities designated for this purpose, as well as internal control and the judicial control. The institution of judicial control of administrative acts and actions appears as very important and widely treated in the legal doctrine. The protection of constitutional and legal rights of private persons is accomplished by subjecting administrative activity both to internal administrative control, as well as to the judicial control in accordance with legal provisions. The judicial control of administrative acts represents a constitutional guarantee for citizens to protect their rights through public and fair trial by an independent and impartial court. In this way, the Constitution empowers the common administrative court that invalidates an action or administrative act, but not all administrative acts may be subject to administrative dispute, with the exception of cases against which the administrative conflict cannot be carried out (negative enumeration.

Tartor, Y H; Hassan, F A M

2017-11-01

This study was designed to investigate the efficacy of essential oils as an alternative prophylaxis and treatment for avian aspergillosis. The in vitro susceptibility of Aspergillus fumigatus strains to antifungal drugs and carvacrol, thymol, eugenol, thymoquinone and cinnamon was determined using the macrodiffusion and microdilution methods. Carvacrol has antifungal activity in comparison to voriconazole (VCZ) (MIC 0·5, 0·25 μg ml -1 respectively). While cinnamon, euganol, thymol and thymoquinone displayed moderate to weak inhibitory activity. For the efficacy study, five groups of 10-day-old chicks (n = 48) were infected intratracheally either with A. fumigatus conidia or saline (negative control). Chicks in carvacrol prophylactic and treatment (CRPT) group were fed for 10 days beginning from hatch with carvacrol (200 mg kg -1 per diet) supplemented diets. VCZ (VCZT:20 mg kg -1 body weight (BW)), carvacrol treatment (CRT, CRPT) was started upon appearance of the first clinical signs and continued for 10 days. Birds were monitored for an additional 15 days following treatment. Fungal burden and therapeutic efficacy were assessed by survival, BW, quantitative (q) culture (CFU), quantitative real-time PCR (qPCR) and histopathological changes at several time points. Serum biochemical changes were also assessed. VCZT, CRPT, CRT in comparison to the sham-treated (SHAM) group have prolonged survival (87·5, 83·4, 79·2, 41·7% respectively). In VCZT and CRPT, a significant reduction in clinical signs, lesions, CFU and qPCR counts to the limit of detection were observed. CRPT has the lowest BW reduction, economic losses and significant low total cholesterol levels. Carvacrol has a promising potential to be used as a prophylactic and treatment against A. fumigatus. Prognosis of avian aspergillosis is often poor due to delayed diagnosis and treatment failure. However, the widespread uses of azole prophylaxis in birds are thought to be the major driver of

Attenuation of pancreatitis-induced pulmonary injury by aerosolized hypertonic saline.

LENUS (Irish Health Repository)

Shields, C J

2012-02-03

BACKGROUND: The immunomodulatory effects of hypertonic saline (HTS) provide potential strategies to attenuate inappropriate inflammatory reactions. This study tested the hypothesis that administration of intratracheal aerosolized HTS modulates the development of lung injury in pancreatitis. METHODS: Pancreatitis was induced in 24 male Sprague-Dawley rats by intraperitoneal injection of 20% L-arginine (500 mg\\/100 g body weight). At 24 and 48 h, intratracheal aerosolized HTS (7.5% NaCl, 0.5 mL) was administered to 8 rats, while a further 8 received 0.5 mL of aerosolized normal saline (NS). At 72 hours, pulmonary neutrophil infiltration (myeloperoxidase activity) and endothelial permeability (bronchoalveolar lavage and wet:dry weight ratios) were assessed. In addition, histological assessment of representative lung tissue was performed by a blinded assessor. In a separate experiment, polymorphonucleocytes (PMN) were isolated from human donors, and exposed to increments of HTS. Neutrophil transmigration across an endothelial cell layer, VEGF release, and apoptosis at 1, 6, 12, 18, and 24 h were assessed. RESULTS: Histopathological lung injury scores were significantly reduced in the HTS group (4.78 +\\/- 1.43 vs. 8.64 +\\/- 0.86); p < 0.001). Pulmonary neutrophil sequestration (1.40 +\\/- 0.2) and increased endothelial permeability (6.77 +\\/- 1.14) were evident in the animals resuscitated with normal saline when compared with HTS (0.70 +\\/- 0.1 and 3.57 +\\/- 1.32), respectively; p < 0.04). HTS significantly reduced PMN transmigration (by 97.1, p = 0.002, and induced PMN apoptosis (p < 0.03). HTS did not impact significantly upon neutrophil VEGF release (p > 0.05). CONCLUSIONS: Intratracheal aerosolized HTS attenuates the neutrophil-mediated pulmonary insult subsequent to pancreatitis. This may represent a novel therapeutic strategy.

Intentional intra-arterial injection of midazolam in a patient with status epilepticus in the intensive care unit

Full Text Available Fundamental medical care includes intravenous (IV access which provides prompt resuscitation and reliable delivery of analgesics, antibiotics, and vasoactive medication. Difficult access populations, especially in critical area, continue to challenge providers to consider and utilize alternative means to provide IV access. Potential options under such circumstances include intramuscular, intraosseous, and intratracheal drug administration, but in extreme cases where no other options are available, intra-arterial route might be considered. We present a case where midazolam was intentionally injected intra-arterially to abort seizure activity in a patient with status epilepticus in the Intensive Care Unit.

Histologic observations on the pathogenesis of lung cancer in hamsters following administration of polonium-210

International Nuclear Information System (INIS)

Lisco, H.; Kennedy, A.R.; Little, J.B.

1974-01-01

A serial sacrifice experiment was carried out to study the site of origin and the stages in development of lung cancer in hamsters induced by polonium-210 ( 210 Po). 1 or 2 animals were sacrificed weekly during and after a course of 7 intratracheal instillations of 0.1 μCi of 210 Po in saline. This exposure produced a transient radiation pneumonitis of moderate severity during, and for several weeks after, the instillation period. Subsequent pathological changes included hyperplasia of bronchiolar epithelium, and focal proliferation of epithelial cells in peribronchiolar and more remote alveoli, termed epithelialization of alveoli. Hyperplastic bronchiolar epithelium frequently showed numerous Clara cells which exhibited pleomorphism of cells and nuclei, multinucleated cells, and striking changes in staining characteristics of secretory granules. Epithelialization of alveoli showed steady progression from well-circumscribed small foci to larger confluent lesions which were composed of various cell types and resembled tumors. Malignant tumors occurred in many animals surviving more than 24 weeks after the last instillation of 210 Po

2014-01-01

To understand the constant increase in administration, we need a new approach to the administration. For many years, the administration has intensified as a closed science, associated only with economics, law and political science. However, this approach did not bring anything good, because almost nothing in the administration has improved. Therefore, it is necessary to connect the administration with the natural sciences which give the best description of the world around us. Because of this...

Pecularities of peripheral blood morphological content in rats in case of combined irradiation of lungs and thyroid

International Nuclear Information System (INIS)

Kulikova, S.B.; Korzhavin, A.N.

1988-01-01

Indices of morphological content of peripheral blood were studied in male rats at 1, 3, 7, 14 days following intratracheal administration of oxide suspension of 147 Nd + 147 Pm and oral administration of 131 I. By 14 days the doses for lungs and thyroid were 5 Gy and 10 Gy respectively. It was shown that the doses of 134 I don't influence morphological indices of peripheral blood but combined effect of radioisotopes leads to moderate increase of leukocyte, lymphocytes and neutrophils. Manifestation of changes in white blood turned out to be less than in case of similar effect of stable isotope on the lungs. Minor shifts in white blood and severity of patholoanatomical picture of inflammatory process in the lungs in case of radioactive isotopes effect can be attributed to specific effect of ionizing radiation. 4 refs.; 2 tabs

Administrative litigation systems in Europe

Directory of Open Access Journals (Sweden)

Cătălin-Silviu Săraru

2017-06-01

Full Text Available The article, analyzing the administrative litigation in the comparative law, groups the existing types of administrative litigation into four major systems, namely: a States with administrative jurisdictions who have the State Council on top, administrative body with consultative and judicial role (the French system; b States with administrative jurisdictions completely separated from the active and consultative administrations (the German system; c States with administrative jurisdictions included in the judicial system; d States with no administrative jurisdiction (English system. The administrative contentious systems analyzed have developed in line with historical evolution and legal traditions and have been continually adapted to the realities existing in each state. The manner in which the administrative contentious is regulated in a State reflects the degree of democratization of that country, the extent to which the citizen enjoys legal safeguards to defend himself against abuses by public authorities. The scientific novelty of this article is to capture the latest trends in the evolution of the administrative contentious systems analyzed. This study aims to provide an easy working tool for reforming administrative litigation on comparative law in states with young democracy. In the research we used the comparative method, the historical and the logical method.

Decision-making in administrative proceeding

Directory of Open Access Journals (Sweden)

Lončar Zoran J.

2015-01-01

Full Text Available Administrative decision-making by official who conducting the administrative procedure may have a number of advantages over the decisionmaking by the senior official which manages by the administrative authority. However, to make that such a novelty have positive effects, it is necessary, next to the amendments to the Law on Administrative Procedure, to create a number of legal and factual assumptions, on whom are based highly politicized and professionalised administrative systems today. In order to create the legal conditions for the introduction of innovations in administrative proceedings in the Republic of Serbia, it is necessary to appropriately modify, firstly certain provisions of the Law on Public Administration, as the basic systemic regulation in this area, and then the Law on Civil Servants, as the basic status regulation, so the civil servant career become less dependent on the will of officials who manage by the administrative authorities. Also, it is essential to solve a number of other issues on a proper legal way, such as way of harmonizing administrative practice within the same administrative authority, a way of solving the appeals in the case of first instance decisions made by independent administrative authority, different rules for conflict of interest with the state officers who may be authorized officials in administrative proceedings, etc.

CONSTITUTIONALIZATION OF ADMINISTRATIVE LAW AND REVIEWABILITY OF THE ADMINISTRATIVE DISCRETION

Directory of Open Access Journals (Sweden)

Luiz Henrique Urquhart Cademartori

2016-07-01

Full Text Available The aim of this article is to conduct an analysis of the constitutionalization of Administrative Law, which results from changes in the rule of law and, under a theoretical standpoint, from the paradigm shift of legal exegesis followed by the advent of neo-constitutionalism, which poses the Constitution as the parameter for the interpretation of the other legal branches. Within this context, considering that the concept of administrative discretion goes through interpretation changes and that administrative activity is performed within the boundaries of discretion, this power/duty must always be used with substantial regulatory criteria in order to get the maximum effectiveness of the constitutional rules, thus being subjected to review. In this sense, it is demonstrated that a public official cannot in any way deviate from the realization of the fundamental rights guaranteed by the Constitution, hence stating the reviewability of the administrative discretion.

The Europeanization of Public Administration through the General Principles of Good Administration

Directory of Open Access Journals (Sweden)

Vasilica NEGRUŢ

2011-08-01

Full Text Available The general objective of the paper is based on an extremely present theme of real interest. Using the content analysis, through a descriptive documentary research, the present study aims at identifying the dimensions of the general principles of good administration, in the context of changes at European an implicitly at national level. To this purpose, an analisys of the specific objectives will be made: the concept of good administration, the national dimensions of the right to be heard, the right to access personal files as well as the motivation of administrative acts and the general principles regulated by the European Code of Good Administration will be underlined, in the context of institutional change determined by the Lisbon Treaty. Good administration defines the way in which institutions function, this being possible by ensuring the right to access information, a more efficient protection of fundamental rights as well as the right to defense, publication of acts and their motivation. Good administration is strongly connected to good government, the relation being in our opinion, from part to whole. The final purpose of good government and implicitly of good administration aims at accomplishing the general interest. The two concepts need a higher degree of transparency and responsibility in the public process. If governing represents the modality of exerting power, good government entails the imperative of the consensus of those governed regarding the objectives and methods of government, the responsibility of those governing, the efficiency of governing and the citizens’ right to be informed regarding the use and the distribution of the financial resources in the governing process. This new concept takes into account the implication of the citizens in the decision - making process, allowing a more efficient use of material, human, and financial resources. We assert thus that by applying the general principles of good administration

Contemporary Education for Public Administration

Directory of Open Access Journals (Sweden)

Ivan Koprić

2007-01-01

Full Text Available The paper examines the development of contemporary administrative education, as a crucial criterion without which it is not possible to achieve professionalism in public administration. While the term professionalism has a variety of meanings, today it is largely deemed that specific educational preparation is a foundation without which other elements of professionalism in public administration cannot be achieved. The level of professionalism, competence, education and knowledge thus become critical variables of administration reforms in transitional countries. Afterwards, the author examines the trends in the development of contemporary administrative education, pointing particularly to the importance of establishing a coherent, vertically passable system, i.e. a system which encompasses all levels of education – from secondary school education to doctoral studies. In this matter, one of the most important features in the development of administrative studies is their diversification, with simultaneous strengthening of the general administrative profile. Thus, the general administrative profile becomes modified, updated and extended by new teaching disciplines. In the final section of the paper, the author addresses the performance of administrative education in Croatia, pointing to its underdevelopment. Indeed, the author suggests that there are no sustainable results of reforms without the training of staff for administration.

Chlorhexidine gluconate (CHX) is an antiseptic that has been widely used for disinfection of cutaneous wound and gingivae. Recently, a patient who inhaled CHX solution died from acute respiratory distress syndrome (ARDS). Although it is highly possible that direct pulmonary damage might be the cause of ARDS, there is no preclinical information about the pulmonary toxicity of CHX. In the current study, the acute direct action of CHX to the lung was evaluated in rats. We successfully exposed the left but not the right lung either to CHX at concentrations of 1%, 0.1%, and 0.01% or to saline using a curved-tip administration tube. At the higher concentrations of CHX (0.1% and 1%), severe congestion to the alveoli and capillaries and perivascular and intra-alveolar hemorrhages were observed 1 day after exposure. Aniline blue-stained collagen fibers with an infiltration of inflammatory cells were present 7 days after exposure. The fibrotic changes and intra-alveolar inflammatory cells had decreased but were still observed sporadically 28 and 84 days after exposure. These detrimental effects were more severe at 1% than at 0.1% CHX. No remarkable effect was observed after exposures to 0.01% CHX and saline. We were able to evaluate the time-course changes in the pulmonary toxicity of CHX by exposures limited to the left lung. It is highly possible that CHX at a concentration of more than 0.1% might directly induce ARDS when aspirated and reaching to the alveoli.

Perspectives on academic veterinary administration.

Science.gov (United States)

Gelberg, H B; Gelberg, S

2001-09-15

It is important for veterinary administrators to apply knowledge bases from other fields to their own unique administrative needs. For example, although some resources are written for business managers, the discussions of four key management competency areas, guidelines for mastering these skills, organizational assessment tools, and other self-help tools may provide interesting food-for-thought for veterinary administrators.(76) In developing their own administrative styles, administrators should seek to apply those principles that seem to intuitively fit with their personal research styles, work situations, managerial styles, administrative preferences, and unique organizational culture. Through strengthening their liaisons with community and university business programs, counseling agencies, employee assistance programs, and psychology researchers, administrators can continue to be exposed to and benefit from new paradigms for consideration in veterinary medical environments. Through these liaisons, the unique needs of veterinary medical environments are also communicated to individuals within the fields of psychology and business, thus stimulating new research that specifically targets veterinary medical environment leadership issues. Each field has unique contributions to help veterinary administrators work toward creating veterinary medical environments that are creative, energetic, visionary, pragmatic, and highly marketable in order to help administrators recruit and nurture the best and brightest veterinary researchers, teachers, and clinicians.

Complex administrative procedures between administrative efficiency and the obligation to protect individual rights

International Nuclear Information System (INIS)

Steinberg, R.

1982-01-01

Due to their structural premise, administrative procedures possess an inordinate amount of influence, especially in complex situations of judicial decision making, to arrive at the ''right decision'' during the passing of binding regulatory ordinances. Since their system of organization is primarily subject to legislative influence, they are governed by the rules of administrative efficiency in the sense of extensive usage of performance - oriented governmental effectuation of constitutional rights. The demands for adequate judicial protection, of which wide administrative court procedure controls are part, will also serve the goal of reaching the ''right administrative decisions.'' (orig.) [de

Human factoring administrative procedures

International Nuclear Information System (INIS)

Grider, D.A.; Sturdivant, M.H.

1991-01-01

In nonnuclear business, administrative procedures bring to mind such mundane topics as filing correspondence and scheduling vacation time. In the nuclear industry, on the other hand, administrative procedures play a vital role in assuring the safe operation of a facility. For some time now, industry focus has been on improving technical procedures. Significant efforts are under way to produce technical procedure requires that a validated technical, regulatory, and administrative basis be developed and that the technical process be established for each procedure. Producing usable technical procedures requires that procedure presentation be engineered to the same human factors principles used in control room design. The vital safety role of administrative procedures requires that they be just as sound, just a rigorously formulated, and documented as technical procedures. Procedure programs at the Tennessee Valley Authority and at Boston Edison's Pilgrim Station demonstrate that human factors engineering techniques can be applied effectively to technical procedures. With a few modifications, those same techniques can be used to produce more effective administrative procedures. Efforts are under way at the US Department of Energy Nuclear Weapons Complex and at some utilities (Boston Edison, for instance) to apply human factors engineering to administrative procedures: The techniques being adapted include the following

MACEDONIAN ADMINISTRATIVE JUDICIAL SYSTEM FOR SOLVING ADMINISTRATIVE DISPUTES COMPARABLE TO EUROPEAN SYSTEMS

Directory of Open Access Journals (Sweden)

Sladjana Eftimova

2015-07-01

Full Text Available The structure of the legal system, through history until today mostly depends on law and policy which is conducted by the country. In European countries, there is position for historical and cultural conceptions for administrative judicature, differences and similarity that leave mark for solving administrative disputes. The obligation – an internal judicial reform to be established in legal system, is conducted by each of the countries after the breaking down and division of Social Federative Republic of Yugoslavia or SFRY due to following the European law for constitution of legitimacy and constitutionality of acts as well as implementing of independent administrative judicature. Analyze of the current condition regarding the independency and objectiveness of the judicature is necessary in our country and it is important to be seen how the conditions for working of the administrative judicature can be improved.

Judicial review of administrative silence

Directory of Open Access Journals (Sweden)

Radošević Ratko S.

2015-01-01

Full Text Available Administrative silence is a situation in which the competent authority, within the statutory deadline, has not issued an administrative act at the request of the party. In the case of administrative silence, given the fact that the citizens are unable to protect their rights and legal interests without an administrative act, they are provided with legal protection. In this case, the same legal relationship is created, directly on the basis of the statute, as in the situation in which the party's request is rejected. This means that the party may, under the conditions prescribed by the statute, initiate the procedure of judicial review of administrative silence. In the paper, the author explains the conditions under which the judicial review of administrative silence can be initiated and the role of the court in this judicial procedure.

Inhalation of carbon black nanoparticles (CBNPs) causes pulmonary inflammation; however, time course data to evaluate the detailed evolution of lung inflammatory responses are lacking. Here we establish a time-series of lung inflammatory response to CBNPs. Female C57BL/6 mice were intratracheally instilled with 162 μg CBNPs alongside vehicle controls. Lung tissues were examined 3 h, and 1, 2, 3, 4, 5, 14, and 42 days (d) post-exposure. Global gene expression and pulmonary inflammation were assessed. DNA damage was evaluated in bronchoalveolar lavage (BAL) cells and lung tissue using the comet assay. Increased neutrophil influx was observed at all time-points. DNA strand breaks were increased in BAL cells 3 h post-exposure, and in lung tissues 2–5 d post-exposure. Approximately 2600 genes were differentially expressed (± 1.5 fold; p ≤ 0.05) across all time-points in the lungs of exposed mice. Altered transcript levels were associated with immune-inflammatory response and acute phase response pathways, consistent with the BAL profiles and expression changes found in common respiratory infectious diseases. Genes involved in DNA repair, apoptosis, cell cycle regulation, and muscle contraction were also differentially expressed. Gene expression changes associated with inflammatory response followed a biphasic pattern, with initial changes at 3 h post-exposure declining to base-levels by 3 d, increasing again at 14 d, and then persisting to 42 d post-exposure. Thus, this single CBNP exposure that was equivalent to nine 8-h working days at the current Danish occupational exposure limit induced biphasic inflammatory response in gene expression that lasted until 42 d post-exposure, raising concern over the chronic effects of CBNP exposure. - Highlights: • A single exposure to CBNPs induced expression changes in over 2600 genes in mouse lungs. • Altered genes were associated with immune-inflammatory and acute phase responses. • Several genes were involved in DNA

Long-term retention of 133Ba in the rat trachea following local administration as barium sulfate particles

International Nuclear Information System (INIS)

Takahashi, S.; Patrick, G.

1987-01-01

Long-term retention of 133 Ba in the trachea from intratracheally administered BaSO 4 particles was determined by both serial sacrifice and external scanning methods up to 6 months after injection. The amount of 133 Ba retained 1 week after injection in the caudal region of the trachea, where the tip of the cannula had been at injection, was 0.41% of the initial dose. Thereafter the 133 Ba was cleared exponentially with a mean half-time of 88 days, as determined from the autopsy samples. The cranial region of the trachea, including the site of the tracheostomy, contained 133 Ba at 10 times the level in the caudal region 1 week after injection and was cleared with a half-time of 66 days. These clearance rates were confirmed by repeated external scanning over the trachea. The 133Ba was drained to the lymph nodes not only in the thoracic cavity but also in the cervical region, suggesting the possibility of lymphatic drainage from the trachea to the cervical lymph nodes

NEITHER FISH NOR FOWL: ADMINISTRATIVE JUDGES IN THE MODERN ADMINISTRATIVE STATE

Directory of Open Access Journals (Sweden)

Russell L. Weaver

2010-10-01

Full Text Available This article examines the role of administrative adjudication in the United States constitutional system. It begins by noting that such adjudication fits uncomfortably within a system of divided powers. Administrative judges, including administrative law judges [ALJs] (who have the highest level of protection and status, are considerably more circumscribed than ordinary Article III judges. Indeed, administrative judges are usually housed in the agencies for which they decide cases, rather than in independent adjudicative bodies, and they do not always have the final say regarding the cases they decide. In many instances, the agency can appeal an adverse administrative judge’s decision directly to the head of the agency, and the agency head retains broad power to overrule the administrative judge’s determinations. In other words, the agency can substitute its judgment for that of the administrative judge regarding factual determinations, legal determinations, and policy choices. As a result, many administrative adjudicative structures involve difficult tradeoffs between independence, political control, and accountability. This article examines issues related to the status and power of administrative judges, as well as the constraints that have been imposed on administrative adjudicative authority, and explores whether those constraints continue to serve the purposes for which they were originally imposed. Cet article examine le rôle du règlement de différends dans le domaine administratif dans le cadre du système constitutionnel des États-Unis. Il note d’abord qu’une telle façon de régler les différends cadre difficilement avec un système où les pouvoirs sont divisés. Les juges administratifs, y inclus les juges de droit administratif (qui jouissent du niveau le plus élevé de protection et de statut, sont considérablement plus restreints que les juges ordinaires sous l’Article III. En effet, les juges administratifs sont

[Administration: practices, myths and ideologies].

Science.gov (United States)

Spinelli, Hugo

2017-01-01

Administration in the social field is examined based on an analysis of its practices, the rationalist myth and its ideological dimensions. In this way, the article discusses the most frequently utilized concepts (administration, management, gerencia, gestión) and their etymologies; the limitations of teaching administration; the complexity of a practice marked by the dimensions of science, art and the social game; and the ideological question underlying the great thought factory that the general theory of administration has been since the start of the 19th century. The article reflects upon the need to construct a theory based in practice contextualized in the global south that goes beyond the classic frames of reference and, above all, to transform administration into a problem to be discussed outside of the knowledge that recognizes it as a technical practice.

Expression kinetics of nucleoside-modified mRNA delivered in lipid nanoparticles to mice by various routes.

Pardi, Norbert; Tuyishime, Steven; Muramatsu, Hiromi; Kariko, Katalin; Mui, Barbara L; Tam, Ying K; Madden, Thomas D; Hope, Michael J; Weissman, Drew

In recent years, in vitro transcribed messenger RNA (mRNA) has emerged as a potential therapeutic platform. To fulfill its promise, effective delivery of mRNA to specific cell types and tissues needs to be achieved. Lipid nanoparticles (LNPs) are efficient carriers for short-interfering RNAs and have entered clinical trials. However, little is known about the potential of LNPs to deliver mRNA. Here, we generated mRNA-LNPs by incorporating HPLC purified, 1-methylpseudouridine-containing mRNA comprising codon-optimized firefly luciferase into stable LNPs. Mice were injected with 0.005-0.250mg/kg doses of mRNA-LNPs by 6 different routes and high levels of protein translation could be measured using in vivo imaging. Subcutaneous, intramuscular and intradermal injection of the LNP-encapsulated mRNA translated locally at the site of injection for up to 10days. For several days, high levels of protein production could be achieved in the lung from the intratracheal administration of mRNA. Intravenous and intraperitoneal and to a lesser extent intramuscular and intratracheal deliveries led to trafficking of mRNA-LNPs systemically resulting in active translation of the mRNA in the liver for 1-4 days. Our results demonstrate that LNPs are appropriate carriers for mRNA in vivo and have the potential to become valuable tools for delivering mRNA encoding therapeutic proteins.

Elastase-coupled beads as a tool for characterizing localized alveolar tissue destruction associated with the onset of emphysema

Science.gov (United States)

Craig, J. M.; Scott, A. L.

2013-01-01

Intratracheal elastase challenge of laboratory animals has long been established as a model for observing the physiological and morphological changes that result from alveolar destruction, the hallmark of emphysema. However, instillation of elastase suspended in buffer results in widespread inflammation and variable emphysematous lesions, which has made the identification of specific cellular and molecular events associated with the onset of emphysema difficult to define. Here we establish a bead-based elastase delivery system that induces localized tissue destruction, a key event in the initiation of emphysema. Elastase was coupled to bisacrylamide beads, which were shown to retain enzymatic activity prior to intratracheal administration in mice. C57BL/6 mice were given a single dose of 40,000 beads, which became distributed throughout the small airways and parenchyma of the lung. Elastase-coupled beads resulted in a quantifiable loss of alveolar tissue immediately surrounding the beads, an effect that was not observed with beads that lacked protein altogether or with beads containing elastase inactivated by an irreversible inhibitor. Furthermore, beads bound with active elastase elicited local recruitment of mononuclear cells, including macrophages, and polymorphonuclear neutrophils to the site of bead deposition, a feature consistent with the cellular infiltration observed following conventional solubilized elastase challenges. This work identifies a novel bead-based enzyme delivery system that also extends the elastase model of emphysema to permit the characterization of mechanisms that drive alveolar surface area loss following elastin degradation in focal emphysematous lesions.

Virtual Reality and Public Administration

Directory of Open Access Journals (Sweden)

István TÓZSA

2013-02-01

Full Text Available This study serves as an introduction to how virtual reality systems could be applied in public administration and what research tasks would be necessary to accomplish a project. E-government solutions began to emerge in public administration approximately a decade ago all over the developed world. Administration service facilities via the Internet did not attract many customers, because of the digital divide. E-government solutions were extended to mobile devices as well, but the expected breakthrough of usage has not ensued. The virtual reality form of public administration services recommended in this study has the most attractive outlay and the simplest navigation tools if compared to ‘traditional’ Internet based e-government. Thus, in accordance with the worldwide amazingly quick spread of the virtual reality systems of Second Life and 3 D types of entertainment, virtual reality applications in public administration could rely on a wide range of acceptance as well.

Fundamentals of the administrative decentralization process

Directory of Open Access Journals (Sweden)

Mihaela Lupăncescu

2017-12-01

Full Text Available Public administration, as an activity carried out by the administrative authorities, can be achieved through several forms of organization. In this sense, centralization, deconcentration and decentralization, together with its corollary, local autonomy, constitute in organizational regimes of an administrative nature, more or less democratic, and with characteristics that vary according to the degree of dependence between the authorities of the public administration institutions at the central level and local public administration authorities.There is no single form of organization that incorporates the characteristics of a particular regime. The complex expectations of modern society have led to the blending of features of different forms of organization in order to create a balance of activity within the public administration, in order to exercise the functions of executive power for the benefit of citizens, not by conferring unlimited autonomy but by considering the fundamental principle of legality.

Metronidazole distribution following intraarterial administration

International Nuclear Information System (INIS)

Konoplyannikov, A.G.; Grigor'ev, A.N.; Zubov, O.G.

1984-01-01

An attempt to achieve a high local concentration of metronidazole in tissues at intraarterial administration in experiments with dogs is made. Intraarterial administration makes it possible to ''saturate'' with a radiosensitizer first of all tissues fed by an artery in question. Administration of the drug to a vessel feeding the tumor would, probably, result in a sharp increase in its concentration in the malignant neoplasm as compared with the rest organs and tissues, which should amplify the radiosensitizing effect

Administrative bias in South Africa

Directory of Open Access Journals (Sweden)

E S Nwauche

2005-01-01

Full Text Available This article reviews the interpretation of section 6(2(aii of the Promotion of Administrative Justice Act which makes an administrator “biased or reasonably suspected of bias” a ground of judicial review. In this regard, the paper reviews the determination of administrative bias in South Africa especially highlighting the concept of institutional bias. The paper notes that inspite of the formulation of the bias ground of review the test for administrative bias is the reasonable apprehension test laid down in the case of President of South Africa v South African Rugby Football Union(2 which on close examination is not the same thing. Accordingly the paper urges an alternative interpretation that is based on the reasonable suspicion test enunciated in BTR Industries South Africa (Pty Ltd v Metal and Allied Workers Union and R v Roberts. Within this context, the paper constructs a model for interpreting the bias ground of review that combines the reasonable suspicion test as interpreted in BTR Industries and R v Roberts, the possibility of the waiver of administrative bias, the curative mechanism of administrative appeal as well as some level of judicial review exemplified by the jurisprudence of article 6(1 of the European Convention of Human Rights, especially in the light of the contemplation of the South African Magistrate Court as a jurisdictional route of judicial review.

THE DECISIONAL TRANSPARENCY IN PUBLIC ADMINISTRATION

Directory of Open Access Journals (Sweden)

OCTAVIA MARIA CILIBIU

2011-04-01

Full Text Available The principle of decisional transparency is one of the principles of good administration, fundamental principles of public administration and it is enshrined in the law of many European Union member states, including our country. In their work the public authorities must show transparency reflected by the active involvement of citizens in administrative decision as its primary beneficiary. The citizen information, consultation and his stimulation to participate actively in the elaboration of draft normative acts for their preparation and before that by bringing them to public knowledge, are tasks of the public authorities which exceed the limit of the obligations imposed by internal rules and are significant efforts to modernize the public administration and rallying to the administrative structures.

Measurement issues associated with using survey data matched with administrative data from the Social Security Administration.

Science.gov (United States)

Davies, Paul S; Fisher, T Lynn

2009-01-01

Researchers using survey data matched with administrative data benefit from the rich demographic and economic detail available from survey data combined with detailed programmatic data from administrative records. The research benefits of using these matched data are too numerous to mention. But there are drawbacks as well, and those drawbacks have received less systematic attention from researchers. We focus on survey data matched with administrative data from the Social Security Administration and address the strengths and weaknesses of each in four specific areas: (1) program participation and benefits, (2) disability and health information, (3) earnings, and (4) deferred compensation. We discuss the implications of these strengths and weaknesses for decisions that researchers must make regarding the appropriate data source and definition for the concepts in question. From this discussion, some general conclusions are drawn about measurement issues associated with using matched survey and administrative data for research, policy evaluation, and statistics.

Nature and scope of public administration

Directory of Open Access Journals (Sweden)

Uchem, R.O.

2013-03-01

Full Text Available The success and survival of any organizations be they government or not is contingent upon group efforts and cooperation to achieve set goals. This paper discusses the nature and scope of public administration to say that in modern day societies, any administration in the public interest transcends beyond government circles and finds expression in other spheres of human endeavors including the church, mosques, postal services as well as international relations and diplomacy, respectively. The paper discusses the concepts of administration and public administration thereby creating a distinction between the two concepts. Furthermore, the understanding of the scope of administration through the various schools of thought have also been captured, the essence of which is to generate a clearer understanding of the discourse under review. The paper ends with conclusions.

Transcultural perspectives in nursing administration.

Science.gov (United States)

Andrews, M M

1998-11-01

Population demographics are reshaping the healthcare work force with respect to race, ethnicity, gender, national origin, sexual orientation, age, handicap, disability, and related factors as national sensitivity to various forms of diversity grows. Given the demographic trends, it is inevitable that nurse administrators will need skill in transcultural administration as they manage diversity and identify the cultural origins of conflict in the multicultural workplace. Culture influences the manner in which administrators, staff and patients perceive, identify, define and solve problems. In this article, the complex and interrelated factors that influence workplace diversity are examined.

Performance Analysis of the Romanian Administration

Directory of Open Access Journals (Sweden)

Marius Constantin PROFIROIU

2013-10-01

Full Text Available The performance of public administration is one of the top priorities of the national governments worldwide, not only for Romania. The role of a performing management system at the level of public administration is to ensure a high quality and efficiency of the adopted policies and strategies, of the provided public services and of the administrative act itself, and to guarantee the advantage of a competitive and efficient administration both in relation to its own citizens, and in competition with other cities and countries throughout Europe and all around the world. Following these considerations, and based upon an empirical research conducted with the aid of a survey regarding ‘The analysis of the performance level of the Romanian public administration’ the article aims to (1 identify modern management tools that determine and influence the performance of Romanian public institutions, (2 analyze the effects of using project management as organizational capacity development instruments by public administration in Romania, and (3 determine the influence and effects of the external factors on the performance and development of Romanian public administration.

7. Administrative structures.

Science.gov (United States)

2014-05-01

The basic systems of any society rarely can operate independently. Instead, they are dependent and often interdependent upon other entities. Such entities control the resources within their respective systems. Thus, coordination and control agencies require contracts or memoranda of understanding with these entities in order to assure access to the resources required during a crisis. These administrative structures include: (1) governmental institutions and agencies, including the military; (2) intergovernmental organisations; (3) nongovernmental organisations; (4) commercial private sector organisations; and (5) academic institutions. These dependencies create potential barriers to the provision of coordination and control including: (1) the complexity of the administrative structures with which coordination and control must interact; (2) the location of resources; (3) finding responsible person(s); (4) the competence and compatibility; (5) methods of access; (6) payment; (7) contracts and memoranda of understanding; (8) inventories of accessible resources; (9) competition for the mandate, power, and resources; and (10) jealousy. The need for potential interactions between administrative structures requires that agreements for the sharing of resources during crises be reached as part of planning and preparedness. Gaining an understanding of these relationships is an important area for research.

Ethics in Public Administration

Directory of Open Access Journals (Sweden)

MSc. Arjeta Hallunovi

2014-06-01

Full Text Available The goal of this study is to deal with some ethical causes in the public administration, that aim the avoidance of negative phenomenon’s as theft, corruption, etc. In this direction, the debates about ethics are becoming more and more a global tendency, as an implement through which would be found the way to get out of the crisis. The success in the reforms of the public administrations in major part depends, on the public functionaries and their willingness to make fundamental changes in the way they work. In this direction, the State should strengthen and modernize the public service, should realize an employment system, which should reflect more the merits on its service. For this reason, the government’s attempts should be concentrated on the construction of a positive image for the state and its administration as professional objective, which is oriented to the services. Being aware for the practical restrictions of this study, we firstly chose to concentrate on the local public administrations ethics. The study will be focused on the practical comparative analysis of the city of Shkodra and Durres by the realization of a questionnaire by each of these municipalities and the Agency of Legalization and Urbanization of Informal Zones (ALUIZNI in Shkodra.

TAX ADMINISTRATION: SOME ISSUES AND TRENDS

Directory of Open Access Journals (Sweden)

MOGOIU CARMEN MIHAELA

2018-02-01

Full Text Available This paper presents a series of practices of tax administrations in different countries of the world, focusing on their functions, mission and responsibilities. Analyzing the main features of tax administrations across the globe, from emerging to top-level, allows self-assessments of their organizations' strengths and weaknesses to describe the current level and identify the steps needed to move to a new level of maturity but I believe that the applicability of best practice should be made after a rigorous analysis of the expected impact and there must be taken into account the differences in national institutional systems, customs, technological progress and the natural resources. A modern and performing tax administration must pay particular attention to the practice of self-evaluation and voluntary compliance, cost reduction and burden diminuation for taxpayers to provide the goods and services needed to increase the standard of living of citizens and ensure economic prosperity. The tax administration plays an important role in developing and modifying fiscal policies by working with other state institutions to monitor the positive or negative impact of fiscal policy and legislation on tax administration, recommending the necessary changes. Studying the best practices of tax administrations around the world can lead to the achievement and maintenance of a high degree of self-assessment and voluntary compliance of taxpayers' tax obligations - the primary objective of any tax administration.

Preparation and in vivo absorption evaluation of spray dried powders containing salmon calcitonin loaded chitosan nanoparticles for pulmonary delivery

Science.gov (United States)

Sinsuebpol, Chutima; Chatchawalsaisin, Jittima; Kulvanich, Poj

2013-01-01

Purpose The aim of the present study was to prepare inhalable co-spray dried powders of salmon calcitonin loaded chitosan nanoparticles (sCT-CS-NPs) with mannitol and investigate pulmonary absorption in rats. Methods The sCT-CS-NPs were prepared by the ionic gelation method using sodium tripolyphosphate (TPP) as a cross-linking polyion. Inhalable dry powders were obtained by co-spray drying aqueous dispersion of sCT-CS-NPs and mannitol. sCT-CS-NPs co-spray dried powders were characterized with respect to morphology, particle size, powder density, aerodynamic diameter, protein integrity, in vitro release of sCT, and aerosolization. The plasmatic sCT levels following intratracheal administration of sCT-CS-NPs spray dried powders to the rats was also determined. Results sCT-CS-NPs were able to be incorporated into mannitol forming inhalable microparticles by the spray drying process. The sCT-CS-NPs/mannitol ratios and spray drying process affected the properties of the microparticles obtained. The conformation of the secondary structures of sCTs was affected by both mannitol content and spray dry inlet temperature. The sCT-CS-NPs were recovered after reconstitution of spray dried powders in an aqueous medium. The sCT release profile from spray dried powders was similar to that from sCT-CS-NPs. In vitro inhalation parameters measured by the Andersen cascade impactor indicated sCT-CS-NPs spray dried powders having promising aerodynamic properties for deposition in the deep lung. Determination of the plasmatic sCT levels following intratracheal administration to rats revealed that the inhalable sCT-CS NPs spray dried powders provided higher protein absorption compared to native sCT powders. Conclusion The sCT-CS-NPs with mannitol based spray dried powders were prepared to have appropriate aerodynamic properties for pulmonary delivery. The developed system was able to deliver sCT via a pulmonary route into the systemic circulation. PMID:24039397

Pulmonary instillation of low doses of titanium dioxide nanoparticles in mice leads to particle retention and gene expression changes in the absence of inflammation

DEFF Research Database (Denmark)

Husain, Mainul; Saber, Anne Thoustrup; Guo, Charles

2013-01-01

We investigated gene expression, protein synthesis, and particle retention in mouse lungs following intratracheal instillation of varying doses of nano-sized titanium dioxide (nano-TiO2). Female C57BL/6 mice were exposed to rutile nano-TiO2 via single intratracheal instillations of 18, 54, and 162......μg/mouse. Mice were sampled 1, 3, and 28days post-exposure. The deposition of nano-TiO2 in the lungs was assessed using nanoscale hyperspectral microscopy. Biological responses in the pulmonary system were analyzed using DNA microarrays, pathway-specific real-time RT-PCR (qPCR), gene-specific q...

Socio-Statistical Research on the Internalization of European Administrative Space Principles in the Romanian Public Administration

Directory of Open Access Journals (Sweden)

Diana-Camelia Iancu

2011-12-01

Full Text Available The authors propose an analysis of the public administration reform in Romania by assessing whether the Romanian civil servants perform their duties according to the regulations of the European Administrative Space. The paper offers a socio-statistic perspective on the internalization of the European Administrative Space principles, namely, the rule of law, openness towards citizens, and public administration responsibility in a Romanian context, after the European Union accession. Designed within the framework of modern theories of organizational sociology that see internalization as a process of organizational learning and change, and using a relevant sample of Romanian civil servants, the paper offers important and useful results for the future Romanian policies and strategies in an integrated European arena.

Motivating administrative acts - doctrinal and jurisprudential issues

Directory of Open Access Journals (Sweden)

Mihai Cristian APOSTOLACHE

2014-06-01

Full Text Available The article approaches the topic of administrative acts motivation, analyzed from the doctrinal and jurisprudential perspective. If at first, motivation was considered merely a formal condition of the administrative act, as a result of the national and European, doctrinal and jurisprudential evolution, motivation is now regarded as one of the most important conditions of validity for the administrative act. Motivating administrative acts represents also a manifestation of the right to information, sealed by the Romanian Constitution, and a dimension of the right to a good administration, as stipulated in the Charter of Fundamental Rights of the European Union.

Administrative skills for academy physicians.

Science.gov (United States)

Aluise, J J; Schmitz, C C; Bland, C J; McArtor, R E

To function effectively within the multifaceted environment of the academic medical center, academic physicians need to heighten their understanding of the economics of the health care system, and further develop their leadership and managerial skills. A literature base on organizational development and management education is now available, which addresses the unique nature of the professional organization, including academic medical centers. This article describes an administration development curriculum for academic physicians. Competency statements, instructional strategies, and references provide health care educators with a model for developing administrative skills programs for academic physicians and other health care professionals. The continuing success of the academic medical center as a responsive health care system may depend on the degree to which academic physicians and their colleagues in other fields gain sophistication in self-management and organizational administration. Health care educators can apply the competencies and instructional strategies offered in this article to administrative development programs for physicians and other health professionals in their institutions.

Genotoxic Evaluation of Mikania laevigata Extract on DNA Damage Caused by Acute Coal Dust Exposure

Energy Technology Data Exchange (ETDEWEB)

Freitas, T.P.; Heuser, V.D.; Tavares, P.; Leffa, D.D.; da Silva, G.A.; Citadini-Zanette, V.; Romao, P.R.T.; Pinho, R.A.; Streck, E.L.; Andrade,V.M. [University of Extremo Catarinense, Criciuma, SC (Brazil)

2009-06-15

We report data on the possible antigenotoxic activity of Mikania laevigata extract (MLE) after acute intratracheal instillation of coal dust using the comet assay in peripheral blood, bone marrow, and liver cells and the micronucleus test in peripheral blood of Wistar rats. The animals were pretreated for 2 weeks with saline solution (groups 1 and 2) or MLE (100 mg/kg) (groups 3 and 4). On day 15, the animals were anesthetized with ketamine (80 mg/kg) and xylazine (20 mg/kg), and gross mineral coal dust (3 mg/0.3 mL saline) (groups 2 and 4) or saline solution (0.3 mL) (groups 1 and 3) was administered directly in the lung by intratracheal administration. Fifteen days after coal dust or saline instillation, the animals were sacrificed, and the femur, liver, and peripheral blood were removed. The results showed a general increase in the DNA damage values at 8 hours for all treatment groups, probably related to surgical procedures that had stressed the animals. Also, liver cells from rats treated with coal dust, pretreated or not with MLE, showed statistically higher comet assay values compared to the control group at 14 days after exposure. These results could be expected because the liver metabolizes a variety of organic compounds to more polar by-products. On the other hand, the micronucleus assay results did not show significant differences among groups. Therefore, our data do not support the antimutagenic activity of M. laevigata as a modulator of DNA damage after acute coal dust instillation.

Effects of transuranics on pulmonary lymph nodes of rodents

International Nuclear Information System (INIS)

Sanders, C.L.

1976-01-01

Pulmonary lymph nodes have been suggested as the ''critical'' tissue for insoluble, inhaled transuranic compounds owing to the high concentration of transuranics in these lymph nodes. About 800 rats were given from 0.2 to 3600 nCi of 238 PuO 2 or 239 PuO 2 by inhalation, intratracheal instillation, intrapleural injection, or intraperitoneal injection. From about 1 to 10 percent of deposited plutonium was translocated to pulmonary lymph nodes, the amount depending on the time after deposition and the route of administration; 238 PuO 2 was cleared from pulmonary lymph nodes faster than 239 PuO 2 owing to the greater in vivo solubility of 238 PuO 2 . No primary tumors of pulmonary lymph nodes were observed, indicating that this tissue was not the critical tissue for carcinogenic induction

ADMINISTRATIVE JUSTICE IN FRANCE. BETWEEN SINGULARITY AND CLASSICISM

Directory of Open Access Journals (Sweden)

H. Flavier

2016-01-01

Full Text Available The administrative justice in France oscillates between classicism and singularity. Multiple factors explain how administrative justice has come to occupy a particular place in French administrative law. Administrative justice has not only settled disputes between administration and private persons, but as well, built the French administrative law. One of the main tasks during 19th and 20th century consisted in strengthen the independence from the executive branch and the efficiency in order to satisfy the idea of good justice. Many reforms have been led since the 1990’s. That is why we propose to depict the French system and evaluate the activity of French administrative justice concerning the judicial organization, its jurisdiction and the remedies before the administrative judge. We will enlighten also our paper with a comparative approach and some statistical elements.

The meaning of the administrative procedure

Directory of Open Access Journals (Sweden)

Martín Loo Gutiérrez

2017-06-01

Full Text Available The article seeks to present a substantive notion of the ‘administrative procedure’, that is, an understanding that departs from the merely procedural or formal meaning that has been consolidated in Chile from the definition adopted by the Administrative Procedures Act (“lbpa” and analyses the institutional purposes that have been assigned to the administrative procedure by foreign literature. The paper develops an explanation about the origins of this formal understanding and exposes the doctrine that has been consolidated in Europe to explain the institution from a substantial point of view. It is argued that this substantive notion can also be constructed in Chile from a systematic reading of some of the provisions of the law on administrative procedures.

The Concept of Appropriateness in Issuing Administrative Acts

Directory of Open Access Journals (Sweden)

Iulian Nedelcu

2011-05-01

Full Text Available Administrative acts are a legal way of organizing the execution and enforcement of the law. Law can not and should not establish all cases and all the ways, by means of which public administration bodies interfere with administrative actions, therefore administrative public bodies must have some initiative and ought to be able to assess the situations in which they will issue these acts and to appreciate their appropriateness. The appropriateness principle of administrative acts must be correlated with the legality principle. It can be concluded that the appropriateness principle underscores the power conferred by public administration, permitted in accordance with which it has the right and duty to judge when issuing an administrative compliance of the state of lawand facts, an appreciation that public administration is based on a single criterion: the interests of the community that they represent. Also, the very organization of the state as a state of law leads to the conclusion that the law – which is the materialization of the idea of justice – should be the standard on which the activity of human individuals report both to the quality of beneficiaries of the provisions and benefits of public administration and on the other hand as officials, public servants or ordinary employees in public administration system.

Philanthropic dilemmas and the nurse administrator role.

Science.gov (United States)

Klein, Tracy

2014-01-01

Nurse administrators are in a position to encounter ethical dilemmas when evaluating philanthropic proposals. Nurses may have little formal training in ethics, or they may be most experienced with ethical frameworks that apply primarily to clinical patient encounters. Gifts of goods, services, education, or other benefits to nurses may create ethical dilemmas. Philanthropic ethics and potential dilemmas are discussed in nonnursing professions such as medicine and nonprofit administration but rarely explored in the nursing administration context. Nurse administrators in a position to evaluate generous offers of philanthropy should identify key components to fully assess the ethics of their receipt. A survey of several resources is done to provide nurse administrators with the foundation to develop policies related to philanthropy if they are absent, preferably in advance of the offer. Recommendations for assessment and evaluation of philanthropic proposals are provided to aid nurse administrators in their synthesis and application of ethical principles from multiple sources.

2017-07-01

Full Text Available Objective(s: Particulate matter (PM exposure can promote cardiac ischemia and myocardial damage. The effects of PM10 on hemodynamic parameters, lipid peroxidation, and infarct size induced by ischemia-reperfusion injury and the protective effects of vanillic acid (VA in isolated rat heart were investigated. Materials and Methods: Eighty male Wistar rats (250–300 g were divided into 8 groups (n=10: Control, Sham, VAc, VA, PMa (0.5 mg/kg PM, intratracheal instillation, PMb (2.5 mg/kg PM, intratracheal instillation, PMc (5 mg/kg PM, intratracheal instillation, and PMc + VA (5 mg/kg PM, intratracheal instillation; and 10 mg/kg vanillic acid, gavage for 10 days. PM10 was instilled into the trachea in two stages, within 48 hr. After isolating the hearts and transfer to a Langendorff apparatus, hearts were subjected to 30 min ischemia and 60 min reperfusion. Hemodynamic parameters (±dp/dt, LVSP, LVDP, and RPP, production of lipid peroxidation (MDA, and infarct size were assessed. Results: A significant decrease in ±dp/dt, LVSP, LVDP and RPP occurred in PM groups. A significant increase in MDA and myocardial infarct size occurred in PM groups. A significant increase in LVDP, LVSP, ±dp/dt, RPP and decrease in infarct size, MDA, and myocardial dysfunction was observed in groups that received vanillic acid after ischemia–reperfusion. Conclusion: It was demonstrated that PM10 increases MDA, as well as the percentage of cardiac infarct size, and has negative effects on hemodynamic parameters. This study suggests that vanillic acid may serve as an adjunctive treatment in delaying the progression of ischemic heart disease.

Learning mechanisms to limit medication administration errors.

Science.gov (United States)

Drach-Zahavy, Anat; Pud, Dorit

2010-04-01

This paper is a report of a study conducted to identify and test the effectiveness of learning mechanisms applied by the nursing staff of hospital wards as a means of limiting medication administration errors. Since the influential report ;To Err Is Human', research has emphasized the role of team learning in reducing medication administration errors. Nevertheless, little is known about the mechanisms underlying team learning. Thirty-two hospital wards were randomly recruited. Data were collected during 2006 in Israel by a multi-method (observations, interviews and administrative data), multi-source (head nurses, bedside nurses) approach. Medication administration error was defined as any deviation from procedures, policies and/or best practices for medication administration, and was identified using semi-structured observations of nurses administering medication. Organizational learning was measured using semi-structured interviews with head nurses, and the previous year's reported medication administration errors were assessed using administrative data. The interview data revealed four learning mechanism patterns employed in an attempt to learn from medication administration errors: integrated, non-integrated, supervisory and patchy learning. Regression analysis results demonstrated that whereas the integrated pattern of learning mechanisms was associated with decreased errors, the non-integrated pattern was associated with increased errors. Supervisory and patchy learning mechanisms were not associated with errors. Superior learning mechanisms are those that represent the whole cycle of team learning, are enacted by nurses who administer medications to patients, and emphasize a system approach to data analysis instead of analysis of individual cases.

Late effects of inhaled 253Es(NO3)3 in rats

International Nuclear Information System (INIS)

Ballou, J.E.; Dagle, G.E.; Gies, R.A.; Smith, L.G.

1979-01-01

Einsteinium-253 nitrate was administered as an aerosol to male Wistar rats and the long-term biological effects were followed for the animals' life span. Lung was the major target organ for absorbed radiation dose and tumor induction, in agreement with results for other inhaled transuranic nitrates. The earlier finding of a high incidence of bone tumors following intratracheal instillation of 253 EsCl 3 was not confirmed in the present study with inhaled 253 Es(NO 3 ) 3 . The reason for the difference in bone tumor production is believed to be related to the different acute toxicities of intratracheally instilled and inhaled 253 Es. Intratracheally instilled 253 EsCl 3 was less acutely toxic (only a single lobe or one-half the lung was irradiated); thus, a larger more tumorigenic dose could be translocated to bone without shortening the life span to the extent that bone tumors could not be expressed. The radiation dose from inhaled 253 Es(NO 3 ) 3 was uniformly spread throughout both lungs and early death due to a generalized radiation pneumonitis precluded the development of long-term effects in bone.

General recommendations for intensivists are made for assessing cooling technology with descriptions of common new technology implementation stages. A study of 16 hospitals implementing a new cardiac surgery technology is described. A description of successful implementation of an induced hypothermia protocol by one of the authors is presented. Although knowledgeable about the applications of new technologies, including cooling technology, intensivists have little guidance or training on tactics to obtain a hospital administration's funding and support. Intensive care unit budgets are usually controlled by nonintensivists whose interests are neutral, at best, to the needs of intensivists. To rise to the top of the large pile of requisition requests, an intensivist's proposal must be well conceived and aligned with hospital administration's strategic goals. Intensivists must understand the hospital acquisition process and administrative structure and participate on high-level hospital committees. Using design thinking and strong leadership skills, the intensivist can marshal support from staff and administrators to successfully implement cooling technology.

Science.gov (United States)

Williamson, James D; Sadofsky, Laura R; Hart, Simon P

2015-03-01

Idiopathic pulmonary fibrosis (IPF) is a devastating disease of unknown etiology, for which there is no curative pharmacological therapy. Bleomycin, an anti-neoplastic agent that causes lung fibrosis in human patients has been used extensively in rodent models to mimic IPF. In this review, we compare the pathogenesis and histological features of human IPF and bleomycin-induced pulmonary fibrosis (BPF) induced in rodents by intratracheal delivery. We discuss the current understanding of IPF and BPF disease development, from the contribution of alveolar epithelial cells and inflammation to the role of fibroblasts and cytokines, and draw conclusions about what we have learned from the intratracheal bleomycin model of lung fibrosis.

Mapping the literature of nursing administration.

Science.gov (United States)

Galganski, Carol J

2006-04-01

As part of Phase I of a project to map the literature of nursing, sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association, this study identifies the core literature cited in nursing administration and the indexing services that provide access to the core journals. The results of this study will assist librarians and end users searching for information related to this nursing discipline, as well as database producers who might consider adding specific titles to their indexing services. Using the common methodology described in the overview article, five source journals for nursing administration were identified and selected for citation analysis over a three-year period, 1996 to 1998, to identify the most frequently cited titles according to Bradford's Law of Scattering. From this core of most productive journal titles, the bibliographic databases that provide the best access to these titles were identified. Results reveal that nursing administration literature relies most heavily on journal articles and on those titles identified as core nursing administrative titles. When the indexing coverage of nine services is compared, PubMed/MEDLINE and CINAHL provide the most comprehensive coverage of this nursing discipline. No one indexing service adequately covers this nursing discipline. Researchers needing comprehensive coverage in this area must search more than one database to effectively research their projects. While PubMed/MEDLINE and CINAHL provide more coverage for this discipline than the other indexing services, none is sufficiently broad in scope to provide indexing of nursing, health care management, and medical literature in a single file. Nurse administrators using the literature to research current work issues need to review not only the nursing titles covered by CINAHL but should also include the major weekly medical titles, core titles in health care administration, and general business sources if they wish to

COMPARATIVE ANALYSIS OF ADMINISTRATIVE AND LEGAL PRINCIPLES OF TAX ADMINISTRATION IN THE CONDITIONS OF DECENTRALIZATION IN EUROPE AND UKRAINE

Full Text Available The aim of the article is a comparative analysis of the administrative and legal regulation of tax administration in European countries and in Ukraine and the definition of ways to improve domestic legislation in this field on this basis. The subject of the study is the administrative and legal principles of tax administration in the conditions of decentralization of state power. Methodology. The study is based on a comparison of the foreign experience of legal regulation and collection of local taxes by using the example of European states with the current state of the process of introducing tax decentralization in Ukraine. Due to the use of this amount of general scientific and specialscientific methods and methods of scientific knowledge, the content of the administrative and legal foundations of tax administration, as well as legal phenomena such as tax decentralization, were characterized and defined. The conclusions that we made helped us to determine the specifics of their administrative-legal regulation in some countries of Europe and in Ukraine. The results of the conducted comparative legal study made it possible to prove the direct impact of tax decentralization on the mechanism of tax administration and the systematic organization of tax authorities. These processes have a predominantly positive impact on macroeconomic processes, they broaden the rights and opportunities of local authorities regarding the use of funds by local governments, forecasting and approving regional budgets, and managing taxes and fees. Practical impact. The administration of taxes in the conditions of decentralization in Europe can be characterized by a high level of efficiency and functionality of the work of the territorial tax-control bodies. This experience is really necessary for Ukraine, where the activities of local self-government in some areas are limited by the central apparatus. Value/originality.

Intraluminal Administration of Poly I:C Causes an Enteropathy That Is Exacerbated by Administration of Oral Dietary Antigen

Science.gov (United States)

Araya, Romina E.; Jury, Jennifer; Bondar, Constanza

2014-01-01

Systemic administration of polyinosinic:polycytidylic acid (poly I:C), mimics virally-induced activation of TLR3 signalling causing acute small intestine damage, but whether and how mucosal administration of poly I:C causes enteropathy is less clear. Our aim was to investigate the inflammatory pathways elicited after intraluminal administration of poly I:C and determine acute and delayed consequences of this locally induced immune activation. Intraluminal poly I:C induced rapid mucosal immune activation in C57BL/6 mice involving IFNβ and the CXCL10/CXCR3 axis, that may drive inflammation towards a Th1 profile. Intraluminal poly I:C also caused enteropathy and gut dysfunction in gliadin-sensitive NOD-DQ8 mice, and this was prolonged by concomitant oral administration of gliadin. Our results indicate that small intestine pathology can be induced in mice by intraluminal administration of poly I:C and that this is exacerbated by subsequent oral delivery of a relevant dietary antigen.

Chilakapati, Shanmuga Reddy; Serasanambati, Mamatha; Manikonda, Pavan Kumar; Chilakapati, Damodar Reddy; Watson, Ronald Ross

2014-08-01

Idiopathic pulmonary fibrosis is a progressive fatal lung disease characterized by excessive collagen deposition, with no effective treatments. We investigated the efficacy of natural products with high anti-inflammatory activity, such as passion fruit peel extract (PFPE), in a mouse model of bleomycin-induced pulmonary fibrosis (PF). C57BL/6J mice were subjected to a single intratracheal instillation of bleomycin to induce PF. Daily PFPE treatment significantly reduced loss of body mass and mortality rate in mice compared with those treated with bleomycin. While bleomycin-induced PF resulted in elevated total numbers of inflammatory cells, macrophages, lymphocytes, and neutrophils in bronchoalveolar lavage fluid on both days 7 and 21, PFPE administration significantly attenuated these phenomena compared with bleomycin group. On day 7, the decreased superoxide dismutase and myeloperoxidase activities observed in the bleomycin group were significantly restored with PFPE treatment. On day 21, enhanced hydroxyproline deposition in the bleomycin group was also suppressed by PFPE administration. PFPE treatment significantly attenuated extensive inflammatory cell infiltration and accumulation of collagen in lung tissue sections of bleomycin-induced mice on days 7 and 21, respectively. Our results indicate that administration of PFPE decreased bleomycin-induced PF because of anti-inflammatory and antioxidant activities.

A series of administrative initiatives undertaken by the Carter Administration in response to public concerns about harmful effects of exposures to ionizing radiation in various settings has been abandoned by the Reagan Administration. The decision to discard the Radiation Policy Council, the coordinating agency established in 1980, leaves the federal government with no overall focus or overall budget for radiation research and protection activities. The line agencies with direct radiation responsibilities, including the Department of Energy, Nuclear Regulatory Commission, Department of Defense, Food and Drug Administration's Bureau of Radiological health, and Department of Labor, continue with somewhat contradictory and uncoordinated programs

The role of GABAB receptors in morphine self-administration

Directory of Open Access Journals (Sweden)

Effat Ramshini

2013-01-01

Full Text Available Background: There is only little information about the effects of GABA receptors agonist and antagonist on morphine self-administration. Present study was designed to assess role of GABAB receptors in the regulation of morphine-reinforced self-administration. Methods: This study was performed in four groups of rats: (1 Saline group, which received saline in the self-administration session. (2 Morphine group, which received morphine in saline solution in the self-administration session. (3 Baclofen + Morphine group, which received both baclofen 20 min before self- administration test and morphine in the self-administration session. (4 Phaclofen + Morphine group, which received both phaclofen 20 min before self- administration test and morphine in the self-administration session. The number of lever pressing and self-infusion were recorded. Results: Morphine significantly increased the number of active lever pressing dose dependently in self-administration session in comparative with saline group. Administration of baclofen, 20 min before morphine self-administration produced significant decrease in the initiation of morphine self-administration during all session. Conversely, pre-treatment of phaclofen increased the number of active lever pressing and self-infusion in this test. Conclusion: Our results indicated a short-term treatment by baclofen, reduced morphine-maintenance response in a dose-dependent manner, suggesting that GABAB receptor agonists could be useful for reversing the neuroadaptations related to opiates.

When there are no legal requirements for the initiation of procedures, the official shall make a decision to reject the application of the party. The procedure is initiated ex officio when stipulated by law or when protection of public interest requires it. When initiating procedure ex officio, the public authority shall take into consideration the petition or other information that indicate the need to protect the public interest. In such cases the applicant is not a party, and the official is obliged to notify the applicant, if initiation of procedures is not accepted ex officio. Based on the notification, the applicant has a right to complain, including the situation when there is no response within the prescribed period of 30 days. Public authority may, therefore it is not obliged to, initiate administrative procedure by public announcement only in a situation where the parties are unknown, while it is obliged to initiate procedure by public announcement when this method of initiating the procedure is prescribed by law. Initiation of procedure with public announcement occurs in rare cases. Due to the application of efficiency and cost-effectiveness principle, two or more administrative procedures can be merged into one procedure by a conclusion. The condition for this is that the rights or obligations of the parties are based on the same legal basis and on the same or

Enemark, Stig

2015-01-01

The term “Fit-For-Purpose Land Administration” indicates that the approach used for building land administration systems in less developed countries should be flexible and focused on serving the purpose of the systems (such as providing security of tenure and control of land use) rather than...... focusing on top-end technical solutions and high accuracy surveys. Of course, such flexibility allows for land administration systems to be incrementally improved over time. This paper unfolds the Fit-For-Purpose concept by analyzing the three core components: The spatial framework (large scale land parcel...... mapping) should be provided using affordable modern technologies such aerial imageries rather than field surveys. The legal framework must support both legal and social tenure, and the regulations must be designed along administrative rather than judicial lines. The fit-for-purpose approach must...

Full Text Available Omnipresent calls for more women in university administration presume women will prioritize using resources and power to increase female representation, especially in STEM fields where women are most underrepresented. However, empirical evidence is lacking for systematic differences in female vs. male administrators' attitudes. Do female administrators agree on which strategies are best, and do men see things differently? We explored United States college and university administrators' opinions regarding strategies, policies, and structural changes in their organizations designed to increase women professors' representation and retention in STEM fields. A comprehensive review of past research yielded a database of potentially-effective, recommended policies. A survey based on these policies was sent to provosts, deans, associate deans, and department chairs of STEM fields at 96 public and private research universities across the U.S. These administrators were asked to rate the quality and feasibility of each strategy; 474 provided data, of which 334 contained complete numerical data used in the analyses. Our data revealed that female (vs. male administrators believed the 44 strategies were higher in quality overall—but not higher in feasibility—with 9 strategies perceived differently by women and men, after imposing conservative statistical controls. There was broad general agreement on the relative-quality rankings of the 44 strategies. Women (vs. men gave higher quality ratings to increasing the value of teaching, service, and administrative experience in tenure/promotion decisions, increasing flexibility of federal-grant funding to accommodate mothers, conducting gender-equity research, and supporting shared tenure lines enabling work-life balance. Women (vs. men believed it was more feasible for men to stop the tenure clock for 1 year for childrearing and for universities to support requests for shared tenure lines, but less feasible for
