  2. Geometric registration of remotely sensed data with SAMIR

    Science.gov (United States)

    Gianinetto, Marco; Barazzetti, Luigi; Dini, Luigi; Fusiello, Andrea; Toldo, Roberto

    2015-06-01

    The commercial market offers several software packages for the registration of remotely sensed data through standard one-to-one image matching. Although very rapid and simple, this strategy does not take into consideration all the interconnections among the images of a multi-temporal data set. This paper presents a new scientific software, called Satellite Automatic Multi-Image Registration (SAMIR), able to extend the traditional registration approach towards multi-image global processing. Tests carried out with high-resolution optical (IKONOS) and high-resolution radar (COSMO-SkyMed) data showed that SAMIR can improve the registration phase with a more rigorous and robust workflow without initial approximations, user's interaction or limitation in spatial/spectral data size. The validation highlighted a sub-pixel accuracy in image co-registration for the considered imaging technologies, including optical and radar imagery.

  3. Remote sensing of atmospheric water content from Bhaskara SAMIR data. [using statistical linear regression analysis

    The 19.35 GHz and 22.235 GHz passive microwave radiometers (SAMIR) on board the Indian satellite Bhaskara have provided very useful data. From these data has been demonstrated the feasibility of deriving atmospheric and ocean surface parameters such as water vapor content, liquid water content, rainfall rate and ocean surface winds. Different approaches have been tried for deriving the atmospheric water content. The statistical and empirical methods have been used by others for the analysis of the Nimbus data. A simulation technique has been attempted for the first time for 19.35 GHz and 22.235 GHz radiometer data. The results obtained from three different methods are compared with radiosonde data. A case study of a tropical depression has been undertaken to demonstrate the capability of Bhaskara SAMIR data to show the variation of total water vapor and liquid water contents.

    Arsenic induced senescence (AIS) has been identified in the population of West Bengal, India very recently. Also there is a high incidence of arsenic induced peripheral neuropathy (PN) throughout India. However, the epigenetic regulation of AIS and its contribution in arsenic induced PN remains unexplored. We recruited seventy two arsenic exposed and forty unexposed individuals from West Bengal to evaluate the role of senescence associated miRNAs (SA-miRs) in AIS and their involvement if any, in PN. The downstream molecules of the miRNA associated with the disease outcome, was also checked by immuoblotting. In vitro studies were conducted with HEK 293 cells and sodium arsenite exposure. Our results show that all the SA-miRs were upregulated in comparison to unexposed controls. miR-29a was the most significantly altered, highest expression being in the arsenic exposed group with PN, suggesting its association with the occurrence of PN. We looked for the expression of peripheral myelin protein 22 (PMP22), a specific target of miR-29a associated with myelination and found that both in vitro and in vivo results showed over-expression of the protein. Since this was quite contrary to miRNA regulation, we checked for intermediate players β-catenin and GSK-3β upon arsenic exposure which affects PMP22 expression. We found that β-catenin was upregulated in vitro and was also highest in the arsenic exposed group with PN while GSK-3β followed the reverse pattern. Our findings suggest that arsenic exposure alters the expression of SA-miRs and the mir-29a/beta catenin/PMP22 axis might be responsible for arsenic induced PN. Copyright © 2017.

    Water scarcity is one of the main factors limiting agricultural development in semi-arid areas. It is thus of major importance to design tools allowing a better management of this resource. Remote sensing has long been used for computing evapotranspiration estimates, which is an input for crop water balance monitoring. Up to now, only medium and low resolution data (e.g. MODIS) are available on regular basis to monitor cultivated areas. However, the increasing availability of high resolution high repetitivity VIS-NIR remote sensing, like the forthcoming Sentinel-2 mission to be lunched in 2015, offers unprecedented opportunity to improve this monitoring. In this study, regional crops water consumption was estimated with the SAMIR software (Satellite of Monitoring Irrigation) using the FAO-56 dual crop coefficient water balance model fed with high resolution NDVI image time series providing estimates of both the actual basal crop coefficient (Kcb) and the vegetation fraction cover. The model includes a soil water model, requiring the knowledge of soil water holding capacity, maximum rooting depth, and water inputs. As irrigations are usually not known on large areas, they are simulated based on rules reproducing the farmer practices. The main objective of this work is to assess the operationality and accuracy of SAMIR at plot and perimeter scales, when several land use types (winter cereals, summer vegetables…), irrigation and agricultural practices are intertwined in a given landscape, including complex canopies such as sparse orchards. Meteorological ground stations were used to compute the reference evapotranspiration and get the rainfall depths. Two time series of ten and fourteen high-resolution SPOT5 have been acquired for the 2008-2009 and 2012-2013 hydrological years over an irrigated area in central Tunisia. They span the various successive crop seasons. The images were radiometrically corrected, first, using the SMAC6s Algorithm, second, using invariant

  9. Inspection systems for valves monitoring at EDF

    International Nuclear Information System (INIS)

    Germain, J.L.; Granal, L.; Provost, D.; Touillez, M.

    1997-01-01

    Electricite de France (EDF) makes increasing use of valve inspection systems to guarantee safety in its pressurized water reactor plants, improve plant availability and facilitate condition-based maintenance. A portable system known as SAMIR has been developed for inspection of motor-operated valves, and is now used on EDF's 900-MW sites. For its 1300-MW units, EDF has chosen a more complete system which enables measuring thrust on the valve stem during a maneuver, using a sensor mounted on the yoke. To detect internal vale leaks, an on-site assessment has demonstrated the economic benefits of acoustic emission techniques. EDF has equipped its sites with analog leak detection systems which may soon be replaced by a digital model now being developed. (authors)

Within a comparative context and using identity theory and diaspora studies, the article illustrates how self-actualization keeps the immigrants from experiencing exile in two Arab American short stories by Pauline Kaldas: “Airport” (2009a and “He Had Dreamed of Returning” (2009b. This article shows how the main characters of “Airport” and “He Had Dreamed of Returning,” Samir and Hani respectively, fulfill the American Dream and how Hoda, Samir’s wife, pictures America as the place where she can realize her ambitions. However, Nancy, Hani’s wife, achieves her potential in Egypt rather than America, where she feels needed as a teacher. Thus, Samir and Hani do not get dislocated in America, and Nancy has a sense of belonging in Egypt. Hence, the article utilizes the American Dream and a reverse side of it, and it shows how Samir’s, Hani’s, and Nancy’s self-actualization is a counter to feelings of exile. In other words, the three characters do not experience loss of identity and displacement in the countries they emigrate to. Rather, they fulfill their dreams there and find/create new identities which have been suppressed in their hometowns, which enhances a view of identity as fluid rather than fixed. Briefly put, this article presents the self-actualization of immigrants in new locales as a counter to different levels of dislocation and exile.

We report a case of endophthalmitis following Listeria monocytogenes keratoconjunctivitis in a 27-year-old healthy white male presenting with hand motion visual acuity, right eye mucopurulent conjunctivitis, elevated intraocular pressure, and pigmented hypopyon 6 months post-keratectomy. The conjunctivitis was unresponsive to a 5-day course of topical tobramycin eye drops, and the patient developed keratitis with pain that progressed to endophthalmitis after 21 days. Diagnostic B-scan revealed vitreous exudates. Intraocular fluid specimen showed Gram-positive organisms and the aqueous culture grew penicillin-/aminoglycoside-sensitive L. monocytogenes. The patient was given intravitreal and systemic vancomycin and ceftazidime. The eye was unresponsive to intravenous penicillin and gentamicin; the anterior chamber progressively flattened and developed phthisis bulbi. L. monocytogenes keratoconjunctivitis may lead to bacterial endophthalmitis. Prompt culture and early antibiotic therapy are recommended.Keywords: conjunctivitis, L. monocytogenes, endophthalmitis

  12. THE LEVANT: ZONE OF CULTURE OR CONFLICT?

    2012-12-01

    Full Text Available Palestinian novelist Samir El-Youssef writes that the question in the title of this essay, “is the Levant a zone of conflict or culture?” is an ironic one indeed. Anyone with a token knowledge of the Levant, argues El-Youssef, knows that these lands are of both conflict and culture; the problem dwells in the fact that the people of the Levant need to be reminded that theirs is a land of great culture that deserves recognition and valorization as such. The author was born and brought up in Rashidiyyé—a Palestinian refugee camp in Southern Lebanon. Rashidiyyé, writes El-Youssef, was and still is as bad as a refugee camp could get. Yet, a mere fifteen minutes walk from the camp stood the ancient Phoenician port-city of Tyr; a harbour town housing the awesome vestiges of one of the greatest, most pacifist, most benevolent builders of civilization.  El-Youssef concludes that "the refugee camp (in its indigence, and the ancient city (in all its glory, standing side by side, are a stark example of the Levant being both a land of conflict and culture."

    Full Text Available Existe la creencia generalizada de que las diferencias internacionales de salarios se deben a las distintas productividades. Esa opinión ha sido cuestionada por diversos economistas. Por ejemplo, Samir Amín observó: “Los trabajadores de la periferia son super-explotados... porque la diferencia en sus salarios (e ingresos no laborables en general es mucho mayor que la diferencia que registran sus productividades.” (Amín 1990, Capítulo 6. Para otros como Prebisch, Singer y Myrdal, “los aumentos de productividad que se obtienen en las naciones desarrolladas, son trasladados a sus trabajadores en forma de salarios e ingresos más altos, mientras que aquellos aumentos obtenidos en la periferia sólo se reflejan en forma de menores precios” (Salvatore 1987: 273. Me propongo agregar algunas reflexiones personales sobre el asunto. Mis observaciones están influenciadas por la crítica a los salarios desde el feminismo, la cual ha establecido que las diferencias de salario entre los sexos son causadas frecuentemente por razones de discriminación, antes que de productividad. Dentro de esta orden de ideas, la tesis de este artículo es que las diferencias internacionales de salarios se deben en gran parte a la discriminación antes que a las diferencias de productividad.

    Full Text Available El objetivo general del presente artículo de investigación consiste en comprender las principales características de los distribuidores mayoristas que componen los canales de distribución de los materiales de construcción de extracción minera en la ciudad de Barranquilla-Colombia, delimitándolo en las siguientes cuatro dimensiones: la operación logística, el nivel de servicio al cliente, las características de la concentración de poder y los conflictos que se presentan entre sus miembros. Los materiales de construcción son una cadena productiva de importancia en el desarrollo social y económico del país y no hay investigaciones recientes sobre el comportamiento de los canales de distribución del sector en Barranquilla- Colombia. La metodología de investigación que se utilizó fue el método del caso mediante la aplicación de entrevistas dirigidas a funcionarios de los distribuidores mayoristas más representativos de la ciudad de Barranquilla como son la Ferretería Samir, la Ferretería Metrópolis y Granitos de la Costa. Se concluye que los transportadores son las unidades especializadas del canal de distribución, ya que permiten el movimiento del producto desde las canteras. Así mismo la decisión de empacar y de transportar aglomerado por parte de los distribuidores mayoristas ha cambiado la estructura de los canales de distribución. El poder se concentra en los transportadores y en los distribuidores mayoristas y finalmente no se encontraron evidencias de conflictos entre los distribuidores mayoristas.

This finding has been attributed to the reaction of having to care for a child with neurodevelopmental disorders. While there have been reports on autism spectrum disorder in Arab/Islamic countries such as Oman, there is no study from this region, to our knowledge, reporting the performance of indices of stress, anxiety, and depression among CASD. This study aimed to examine whether there is variation in the performance of indices of stress, depression, and anxiety explored via Depression, Anxiety and Stress Scale 21 among CASD, caregivers of children with intellectual disabilities, and caregivers of typically developing children. All indices of stress, depression, and anxiety were higher in CASD compared to other caregivers in the control group. This study corroborates with other studies carried out in other populations that caring for children impacts the mental health status of caregivers. Therefore, there are strong grounds to contemplate the mechanism to help such a vulnerable group of family caregivers. Keywords: stress, anxiety, depression, caregivers, autism, Oman

Analysis of the plasma AA profile, together with markers of glucose and lipid metabolism, will shed light on metabolic regulation. The objectives of this study were to investigate the acute responses to the consumption of meals containing either pork (PM or chicken (CM, and to identify relationships between plasma AA and markers of glycemic and lipemic control. A secondary aim was to explore AA predictors of plasma zinc concentrations. Ten healthy adults participated in a postprandial study on two separate occasions. In a randomized cross-over design, participants consumed PM or CM. The concentrations of 21 AA, glucose, insulin, triglycerides, nonesterified fatty acids, and zinc were determined over 5 hours postprandially. The meal composition did not influence glucose, insulin, triglyceride, nonesterified fatty acid, or zinc concentrations. Plasma histidine was higher following the consumption of PM (P=0.014, with consistently higher changes observed after 60 minutes (P<0.001. Greater percentage increases were noted at limited time points for valine and leucine + isoleucine in those who consumed CM compared to PM. In linear regression, some AAs emerged as predictors of the metabolic responses, irrespective of the meal that was consumed. The present study demonstrates that a single meal of PM or CM produces a differential profile of AA in the

  3. The Mechanism of the Silencing of a Transgene, NCED3‐LUC, in Arabidopsis Thaliana

    The Arabidopsis thaliana NCED3‐LUC transgenic line was constructed by several groups to study the regulatory network of the NCED3 gene, the protein of which catalyzes the rate‐limiting step of ABA biosynthesis under drought. The transgenic luciferase gene is expressed when the plants encounter drought stress. Intriguingly, this transgenic luciferase gene is silenced after propagation for several generations. To determine the mechanism of this gene silencing, we used a forward genetics approach. The seeds of NCED3‐LUC (referred as the ‘wild type’) were mutagenized by ethane methyl sulfonate (EMS). One mutant line, denoted as #73, with recovered luciferase activity was selected for further study. Analysis of the methylation status by bisulfite sequencing revealed that the transgenic NCED3 promoter in the #73 mutant had less methylation than the wild type. Demethylation was also evident for the endogenous NCED3 promoter and retrotransposon AtSN1 in the #73 mutant. The phenotype of #73 mutant includes small size, rapid dehydration rate, altered morphology, and a thin epicuticular wax layer. By use of map‐based cloning, the region containing the mutated gene was delimited to a contig of two BAC clones, F11F19 and F9C22, on chromosome 2. Our results indicate that NCED3‐LUC gene silencing results from hypermethylation of its promoter region, but additional study is required to determine the exact position of the mutated gene and to fully understand the mechanism of NCED3‐LUC silencing. 4 ACKNOWLEDGEMENTS I would like to take this opportunity to thank my committee chair, Professor Jian‐Kang Zhu, who is also the supervisor of my master’s thesis, for his guidance throughout the course of this research.

While PCOS has been reported in Arab countries such as Oman, there is a dearth of studies of the occurrence of psychological burden among PCOS women in the Arab region. This study aimed to compare sociodemographic and clinical characteristics of PCOS women diagnosed with non-PCOS women and prevalence of severity of depression, anxiety and stress and to explore the association between PCOS and indices of psychological disturbances after adjusting for potential confounding factors.Patients and methods: This hospital-based case–control study was conducted among women aged 16–49 years. The study included 52 women diagnosed with PCOS (as per Rotterdam 2003 criteria and 60 control who were PCOS-free. The presence of psychological burden – depression, anxiety and stress – was quantified using Depression, Anxiety and Stress Scale-21 (DASS-21.Results: The crude odds ratios (ORs generated by logistic regression models indicated an increased risk of depression, anxiety and stress among women with PCOS compared to controls.

The prevailing view in the literature is that mothers of drug-dependent patients can be characterized by strong emotional bonds and overprotection. Studies suggest that maternal rejection could be a major risk factor of developing drug addiction. This work is a continuation of our previous study of childhood parenting experiences of substance-dependent patients. The aims were to compare the personality profile of mothers of substance-dependent patients and that of mothers of matched control subjects; and to examine the relation between the personality of mothers of addicts, and severity of their offspring’s addiction. The study group consisted of 20 mothers of substance-dependent patients and a control group of 35 mothers of non-dependent subjects; mothers of both groups were age matched. Patients were diagnosed according to DSM IV criteria. Personalities of mothers of both groups were assessed using the Minnesota Multiphasic Personality Inventory (MMPI. Substance-dependent patients (sons were administered the Addiction Severity Index (ASI. The mean scores of the MMPI Scales were higher for mothers of dependent patients compared to mothers of non-dependent subjects. Scores on the depression, hysteria and paranoia scales were significantly higher for mothers of patients (P = 0.03, 0.02, and 0.03, respectively. There was a significant positive correlation between scores of hysteria, and psychopathic deviance and the ASI (P = 0.03 and 0.01, respectively. There were significant negative correlations between scores of social introversion and the ASI drug/alcohol use status (P = 0.007, and family history dimensions (P = 0.003. Mothers of substance-dependent patients showed disturbances in aspects of personalities

    The Haouz plain (6000 km2) is a part of the Tensift basin located in the Central Morocco. The plain has a semi-arid climate (250 mm/y of rainfall) and is bordered in the south by the High-Atlas mountains. Because the plain is highly anthropized, the water resources face heavy demands from various competing sectors, including agriculture (over than 273000 ha of irrigated areas), water supply for more than 2 million inhabitants and about 2 millions of tourists annually. Consequently the groundwater is being depleted on a large area of the plain, with problems of water scarcity which pose serious threats to water supplies and to sustainable development. The groundwater in the Haouz plain was modeled previously by MODFLOW (USGS groundwater numerical modeling) with annual time steps. In the present study a multi-modeling approach is applied. The aim is to enhance the evaluation of the groundwater pumping for irrigation, one of the most difficult data to estimate, and to improve the water balance assessment. In this purpose, two other models were added: SAMIR (Satellite Estimation of Agricultural Water Demand) and WEAP (integrated water resources planning). The three models are implemented at a monthly time step and calibrated over the 2001-2011 period, corresponding to 120 time steps. This multi-modeling allows assessing the evolution of water resources both in time and space. The results show deep changes during the last years which affect generally the water resources and groundwater particularly. These changes are induced by a remarkable urbanism development, succession of droughts, intensive agriculture activities and weak management of irrigation and water resources. Some indicators of these changes are as follow: (i) the groundwater table decrease varies between 1 to 3m/year, (ii) the groundwater depletion during the last ten year is equivalent to 50% of the lost reserves during 40 years, (iii) the annual groundwater deficit is about 100 hm3, (iv) the renewable

The prevalence of coronary heart disease is promoted in turn by a high prevalence of cardiovascular risk factors, particularly smoking, hypertension, dyslipidemia, diabetes, and sedentary lifestyles. Patients in Africa and the Middle East present with myocardial infarction at a younger age, on average, compared with patients elsewhere. The projected future burden of mortality from coronary heart disease in Africa and the Middle East is set to outstrip that observed in other geographical regions. Recent detailed nationally representative epidemiological data are lacking for many countries, and high proportions of transient expatriate workers in countries such as Saudi Arabia and the United Arab Emirates complicate the construction of such datasets. However, the development of national registries in some countries is beginning to reveal the nature of coronary heart disease. Improving lifestyles (reducing calorie intake and increasing physical activity in patients in the region will be essential, although cultural and environmental barriers will render this difficult. Appropriate prescribing of pharmacologic treatments is essential in the prevention and management of cardiovascular disease. In particular, recent controversies relating to the therapeutic profile of beta-blockers may have reduced their use. The

It has been shown to exert effects through multiple pathways, some actions suggested to be mediated via N-arachidonoylphenolamine (AM404. AM404, formed through conjugation of paracetamol-derived p-aminophenol with arachidonic acid in the brain, is an activator of the capsaicin receptor, TRPV1, and inhibits the reuptake of the endocannabinoid, anandamide, into postsynaptic ­neurons, as well as inhibiting synthesis of PGE2 by COX-2. However, the presence of AM404 in the central nervous system following administration of paracetamol has not yet been demonstrated in humans. Cerebrospinal fluid (CSF and blood were collected from 26 adult male patients between 10 and 211 minutes following intravenous administration of 1 g of paracetamol. Paracetamol was measured by high-performance liquid chromatography with UV detection. AM404 was measured by liquid chromatography-tandem mass spectrometry. AM404 was detected in 17 of the 26 evaluable CSF samples at 5–40 nmol⋅L–1. Paracetamol was measurable in CSF within 10 minutes, with a maximum measured concentration of 60 μmol⋅L–1 at 206 minutes. This study is the first to report on the presence of AM404 in human CSF following paracetamol administration. This may represent an important finding in our understanding of

An autonomous wireless data system (AWDS comprising of a WIT and an external antenna aided by a motion sensor provided continuous IOP readings. The sensitivity of the technique was determined by the ability to detect IOP changes resulting from the administration of latanoprost 0.005% or dorzolamide 2%, while the reliability was determined by the agreement between baseline and vehicle (saline IOP.Results: On average, 12 diurnal and 205 nocturnal IOP measurements were performed with latanoprost, and 26 diurnal and 205 nocturnal measurements with dorzolamide. No difference was found between mean baseline IOP (13.08±2.2 mmHg and mean vehicle IOP (13.27±2.1 mmHg (P=0.45, suggesting good measurement reliability. Both antiglaucoma medications caused significant IOP reduction compared to baseline; latanoprost reduced mean IOP by 10% (1.3±3.54 mmHg; P<0.001, and dorzolamide by 5% (0.62±2.22 mmHg; P<0.001. Use of latanoprost resulted in an overall twofold higher IOP reduction compared to dorzolamide (P<0.001. Repeatability was ±1.8 mmHg, assessed by the variability of consecutive IOP measurements performed in a short period of time (≤1 minute, during which the IOP is not expected to change.Conclusion: IOP measurements in conscious rabbits obtained without the need for human interactions using the AWDS are feasible and provide reproducible results.Keywords: IOP, pressure transducer, wireless, MEMS, implant, intraocular

Evidence also suggests that radiotherapy (RT omission may be reasonable for some patients over 70 years. Among radiation-delivery techniques, intensity-modulated RT (IMRT is more expensive than 3-dimensional conformal RT (3DCRT. Based on this evidence, in 2013, the American Society for Radiation Oncology (ASTRO recommended hypofractionated schedules for women aged ≥50 years with early-stage breast cancer and avoiding routine use of IMRT for WBRT. To assess response to level I evidence and adherence to ASTRO recommendations, we evaluated the pattern of RT use for early-stage breast cancer at our National Comprehensive Cancer Network institution from 2006 to 2008 and 2011 to 2013 and compared the results with national trends. Methods: Data from a prospective database were extracted to include patients treated with BCT, aged ≥50 years, with histologic findings of invasive ductal carcinoma, stage T1-T2N0M0, estrogen receptor-positive, and HER2 normal. We retrospectively reviewed the medical records and estimated costs based on 2016 Hospital Outpatient Prospective Payment System (technical fees and Medicare Physician Fee Schedule (professional fees. Results: Among 55 cases from 2006 to 2008, treatment regimens were 11% hypofractionated, 69% traditional schedule, and 20% RT omission (29% of patients were aged >70 years. Among 83 cases from 2011 to 2013, treatment regimens were 54% hypofractionated, 19% traditional schedule, and 27% RT omission (48% of patients were aged >70

Biochemical and anthropometric measurements correlated with increased levels of these antibodies are also controversial, especially in conditions of impaired glucose tolerance and type 2 diabetes mellitus. The present study was conducted to evaluate levels of oxLDL antibodies and their correlation with obesity in different glycemic situations. Methods: Two hundred and seventy-four adult males were classified into three subgroups: group 1 (n=125, comprising a control group of nondiabetic subjects; group 2 (n=77, comprising subjects with impaired glucose tolerance; and group 3 (n=72, comprising patients with type 2 diabetes mellitus. Body mass index was calculated, and measurement of oxLDL and oxLDL antibodies was performed. Results: Higher mean concentrations of oxLDL were found in the type 2 diabetes mellitus and impaired glucose tolerance groups (143.5±21.9 U/L and 108.7±23.7 U/L, respectively. The mean value for the control group was 73.5±27.5 U/L (P<0.001. Higher mean concentrations of anti-oxLDL antibodies were observed in the type 2 diabetes mellitus and impaired

However, their potential vascular and systemic pathophysiologic effects are not fully understood. Here, we investigated the acute (24 hours systemic toxicity of intraperitoneally administered 50 nm and 500 nm SiNPs in mice (0.5 mg/kg. Both sizes of SiNPs induced a platelet proaggregatory effect in pial venules and increased plasma concentration of plasminogen activator inhibitor-1. Elevated plasma levels of von Willebrand factor and fibrinogen and a decrease in the number of circulating platelets were only seen following the administration of 50 nm SiNPs. The direct addition of SiNPs to untreated mouse blood significantly induced in vitro platelet aggregation in a dose-dependent fashion, and these effects were more pronounced with 50 nm SiNPs. Both sizes of SiNPs increased lactate dehydrogenase activity and interleukin 1β concentration. However, tumor necrosis factor α concentration was only increased after the administration of 50 nm SiNPs. Nevertheless, plasma markers of oxidative stress, including 8-isoprostane
