Detection of Nitrate(NO-2) Ions Produced in Disproportionation of Nitrogen(II) Oxide in Aqueous Solution
Aleksander Kufelnicki , Jolanta Jaciubek-Rosińska
Ecological Chemistry and Engineering S , 2012, DOI: 10.2478/v10216-011-0004-0
Abstract: The nitrate ions (NO-2), products of disproportionation of NO in aqueous solution, were detected by an Orion Nitrite Electrode 97-46. Calibrations by means of standard NaNO2 solutions within the range 0.001÷100 ppm indicated linear dependence of EMF on ppm within 1÷100 ppm. Measurements justified the usefulness of this detection method of NO in solutions of OH- concentration lower than 10-2 mol dm-3 since at higher concentrations the EMF values exceeded the measurement range of the electrode. Occurrence of nitrate ions produced in the disproportionation reaction was additionally confirmed in dependence of OH- concentration by near UV and fluorescence spectra. The calibrated ion-selective nitrate electrode has also been shown, on the basis of Co(II)-dipeptide-OH- systems, as a useful tool in studying reversible NO uptake by Co(II) chelates in aqueous solution. Such a reaction may be regarded as simulating the harmful binding of NO by hemoglobin, where it substitutes the isoelectronic dioxygen.

Abstract: Objectives To assess life satisfaction, job satisfaction, life orientation and the level of professional burnout in a group of professionally active nurses and midwives. Design A cross-sectional study. Setting This study was conducted between March and October of 2017 during specialisation training at the European Centre for Postgraduate Education in Wroclaw, Poland. Participants A group of 350 professionally active nurses (n=293) and midwives (n=57) were enrolled in the study. Outcome measures Associations between burnout and selected life-related and job-related outcomes using (1) the Satisfaction With Job Scale, (2) the Satisfaction With Life Scale (SWLS), (3) the Life Orientation Test-Revised, (4) the Maslach Burnout Inventory and the Authors’ Designed Questionnaire regarding sociodemographic factors. The level of statistical significance was set at p≤0.05 (with a CI of 95%). Results The vast majority of participants were those in the ages of 41–50 years old (40.57%), women (96.86%) and people with bachelor’s degree (46.29%). The average overall rate for occupational burnout was 34.67 per 100 points. Assessment of occupational burnout subscale showed that the most significant factor was emotional exhaustion at 39.14 points (SD=28.15). Job satisfaction, life satisfaction and life orientation assessed with SWLS significantly affects each of the occupational burnout subscales (p<0.05). Conclusions The level of occupational burnout in nurses and midwives appeared to be low. It has been revealed that such determinants as life satisfaction, job satisfaction and life orientation do not allow for developing an occupational burnout
Cognitive and behavioral predictors in the process of smoking cessation during pregnancy: Testing for discontinuity patterns in the Transtheoretical Model

Abstract: The aim of the study was to assess predictive power of cognitive variables and health-promoting behaviors for the process of smoking cessation described in terms of the Transtheoretical Model (TTM). Participants in the study were 150 women (mean age 26.93, SD = 4.56 years), in uncomplicated pregnancy. Cigarette smokers constituted 29.3% of the sample, while the rest had previously quitted smoking (in that number 42.1% during pregnancy). Beliefs and expectations were measured by means of scales developed by the author, while health-related behaviors were assessed using the Health Behavior Inventory (HBI) by Z. Juczyński, supplemented with pregnancy-specific behaviors. TTM discontinuity patterns were tested in the study using polynomial-based orthogonal contrasts. Statistically significant linear trends were found for expectations concerning the infant's health state and the course of delivery, for beliefs about the effect of maternal smoking on infant health, as well as for pregnancy health behaviors. The obtained results were confirmed by hierarchical regression analysis, with smoking cessation explained to a larger extent by cognitive factors than by health-related behaviors. This may suggest that the TTM is a "pseudo-stage" model, and a general change of the variables under study is of greater importance for the process of smoking cessation than focusing on the TTM stages.

Simultaneous Quantification of Chosen Organic Micropollutants in Drinking Water？
Agata Rosińska,Patrycja Sobczak
Proceedings | An Open Access Journal from MDPI , 2019, DOI: https://doi.org/10.3390/proceedings2019016008
Abstract: An analytical method that can allow one to determine simultaneously chosen organic micropollutants has been developed to measure their concentrations in water. Standard mixture of 16 polycyclic aromatic hydrocarbons (PAH) and nine polychlorinated biphenyls (PCB) was added to distilled water in a specific amount. The solid phase extraction (SPE) method was applied. Isopropyl alcohol and methanol were used to precondition SPE extraction columns. PAH and PCB were eluted from the column fillings using dichloromethane. Extracts were condensed to a volume of 2 mL. Prepared samples were analyzed with the use of gas chromatography and mass spectrometry. The achieved percent recovery of PAH was from around 7% in the case of chrysene to 100% in the case of naphthalene. The achieved percent recovery of PCB was from about 51% in the case of PCB 101 to 92% in the case of PCB 156
Application of Texture Measures to Study Effect of B Chromosomes on the 3D Architecture of Plant Chromatin  [PDF]

Abstract: Background: Supernumerary chromosomes (B) comprise optional complement to basic (A) chromosome set. The presence of B-chromosomes may significantly reduce plant vigor and fertility. Potentially active genes constitute only small fraction of DNA of these chromosomes indicating that these effects are mediated by epigenetic mechanisms. One example is down-regulation of rDNA genes and condensation of their respective chromatin regions (demonstrated in squashed preparations using 2D microscopy). It may be postulated that the presence of B chromosomes leads to more extensive changes of local chromatin structure. Verification of hypothesis requires studying 3D spatial architecture of intact nuclei in tissue. Results: An image processing algorithm was developed and applied for isolation (from the confocal datasets) of regions corresponding to single nuclei. The nuclei were segmented using iterative global thresholding followed by growing and merging of regions belonging to different nuclei. The result of segmentation was verified by a human observer. Chromatin architecture was characterized quantitatively using global fluorescence intensity distribution measures (mean, variance) and local intensity distribution parameters (haraclick features, wavelet energy, run- length features). The sets of parameters corresponding to populations of nuclei with different number of B-chromo- somes were subjected to discriminate analysis. The distinct parameters were then correlated with depth in tissue at which a given nucleus was positioned. Conclusions: Combination of light microscopy with dedicated image processing and analysis framework made it possible to study chromatin architecture in nuclei containing various number of B chromosomes. These data indicate that alterations of 3D chromatin distribution occur globally in the interphase nuclei in the presence of Bs. The changes occur at the spatial scale comparable with the resolution limit of light microscopy and at larger distances.

Advances in Alzheimer's Disease (AAD) , 2013, DOI: 10.4236/aad.2013.21001
Abstract:

Alzheimer’s disease (AD) is accompanied by elevated levels of homocysteine (Hcy). Homocysteine may induce elevated concentration of asymmetric dimethylarginine (ADMA). Both Hcy and ADMA are the amino acids thought to represent risk factors of vascular diseases. Studies were conducted on the plasma levels of Hcy and methionine (Met), estimated by HPLC with electrochemical detection, as well as on levels of ADMA and arginine (Arg), estimated by HPLC with fluorescent detection, in the AD patients with benign through to severe dementia estimated by MMSE scale and in a control group. The studies disclosed elevated levels of Hcy and ADMA in AD (Hcy, p < 0.001) as compared to controls, as well as in subjects older than 60 years of age (Hcy, p < 0.01). The AD patients with severe dementia have shown elevated levels of Hcy (p < 0.05) as compared to the patients with moderate dementia. The concentration of Metand Arg showed a downward trend in AD patientswith severe dementia. The highest levels of ADMA have been demonstrated in AD patients in the early stages of the disease. In parallel, in AD with varying degrees of dementia and subjects older than 60 years of age a disturbed turnover was observed of Hcy to Met and of Arg to ADMA. Similarly to Hcy, ADMA seems to be a potential risk factor of AD and important factor for progress of dementia.

Alien species of fish parasites in the coastal lakes and lagoons of the southern Baltic
Jolanta Morozińska-Gogol
Oceanologia , 2009,
Abstract: Alien species are now found all over the world. New fish parasites have been unintentionally introduced with infected alien fish imported for aquaculture or have sometimes spread with their intermediate invertebrate hosts transported in the ballast waters of ships. Four alien fish parasites have been recorded in Polish coastal lakes and lagoons, all parasitising eels. Three were introduced with the final host - the Japanese eel - introduced for aquaculture (Anguillicola crassus, Pseudodactylogyrus anguillae and Pseudodactylogyrus bini) and one (Paratenuisentis ambiguus) with its sole intermediate host (Gammarus tigrinus).
