Regulatory factors of basal F2-isoprostane formation: Population, age, gender and smoking habits in humans
No full textOxidative stress is assumed to be the key underlying factor in the pathogenesis of many common diseases. This study describes the basal levels of 8-iso-PGF(2alpha ), a major F(2)-isoprostane and an in vivo oxidative stress biomarker in healthy subjects from three countries, namely Italy, Poland and Sweden, in relation to their smoking habits, age and gender. It studied urinary 8-iso-PGF(2alpha ) in 588 subjects from Sweden (n=220), Italy (n=203) and Poland (n=165). Polish subjects had the highest levels of F(2)-isoprostanes followed by the Swedish and Italians when adjusted for smoking, age, sex and creatinine and the inter-country differences were statistically significant. Smokers had significantly higher levels of 8-iso-PGF(2alpha ) compared to non-smokers in all countries and there was a moderate decrease with age. Women had only slightly lower 8-iso-PGF(2alpha ) than men. There is a difference in F(2)-isoprostane levels in vivo between countries. Smoking, age and gender affect isoprostane formation and should be taken into consideration in clinical studies of oxidative stress.</p

Exhaled breath condensate biomarkers of airway inflammation and oxidative stress in COPD
No full textExhaled breath condensate (EBC) is a noninvasive method for collecting airway secretions and for
studying the composition of the airway lining fluid. Several biomolecules, including leukotrienes,
prostaglandins, isoprostanes, hydrogen peroxide, nitric oxide-derived products, hydrogen ions, and
adenosine triphosphate, have been measured in healthy subjects. Some of these inflammatory mediators are elevated in patients with chronic obstructive pulmonary disease (COPD). Analysis of biomolecules in EBC is potentially useful for monitoring of lung inflammation and oxidative stress, which is an important component of inflammation, in patients with COPD. As it is completely noninvasive, EBC might also be suitable for longitudinal studies, and for monitoring the effects of pharmacological therapy in patients with
COPD. Different profiles of biomarkers in EBC might reflect different aspects of lung inflammation or
oxidative stress. Identification of selective profiles of biomarkers in EBC in lung diseases might have a
value for differential diagnosis in respiratory medicine. However, several methodological aspects have to be formally addressed and standardization of EBC methodology is required before this technique can be considered for application in the clinical setting

Inflammatory F-2-isoprostane, prostaglandin F-2 alpha, pentraxin 3 levels and breast cancer risk: The Swedish Mammography Cohort
No full textThe authors greatfully acknowledge Prof. Karl Michaelsson for providing support in the organisation of SMC cohort and technical assistance of Ms. Lillemor Kallstrom and Ms. Carina Branstrom. The authors are indebted to the Conseil Regional d'Auvergne, Clermont-Ferrand, France and the Clermont Universite, University d'Auvergne, Clermont-Ferrand, France for a Chaire d'Excellence Professor to Samar Basu and a Research Grant to Prof. Samar Basu and Prof. Marie-Paule Vasson to support the workIntroduction:Breast cancer is a common cancer among women. Identifying cellular participation of F-2-isoprostane, prostaglandin F-2 alpha, (PGF(2 alpha)) and pentraxin 3 (PTX3) in cancer we evaluated whether their prediagnostic systemic levels that originate from different inflammatory pathways were associated with breast cancer risk.Methods: Seventy-eight breast cancer cases diagnosed after blood collection and 797 controls from the Swedish Mammography Cohort were analysed for urinary F-2-isoprostane, PGF(2 alpha) and plasma PTX3 levels.Results: None of the biomarkers investigated were significantly associated with breast cancer risk. However, there was the suggestion of an inverse association with PTX3 with multivariable adjusted ORs (95% CI) of 0.56 (95% CI=0.29-1.06) and 0.67 (95% CI=0.35-1.28) for the second and third tertiles, respectively (p(trend)=0.20). No associations were observed between F-2-isoprostane (OR=0.87; 95% Cl=048-1.57; p(trend)=0.67) and PGF(2 alpha) metabolite (OR=1.03; 95% CI=0.56-1.88; p(trend)=0.91) comparing the top to bottom tertiles.Conclusions: The systemic levels of F-2-isoprostane, PGF(2 alpha) and PTX3 witnessed in women who later developed breast cancer may not provide prognostic information regarding tumor development in spite of their known involvement in situ cellular context. These observations may indicate that other mechanisms exist in controlling cellular formation of F-2-isoprostane, PGF(2 alpha) and PTX3 and their systemic availability in breast cancer patient
Magnanimous Kunti by Samaresh Basu/ সমরেশ বসুর কলমে মনস্বিনী কুন্তী
No full textSamaresh Basu wrote a number of books based on Puran-Mahabharata under the pseudonym Bhramar and Kalkoot. Such as, ‘Shamba (1978)’, ‘Juddher Sesh Senapati (1984)’, ‘Prachetas (1984)’, \u27Pritha (1986)\u27, ‘Antim Pranay (1987)’ etc. ‘Pritha’ was published in the magazine \u27Prasad\u27 under the pseudonym \u27Bhramar\u27. In such books, the author analyzed the traditional story of the Puranas in a new perspective.
One of the memorable Panchakanyas in Puranas, Empress Kunti has been recreated in the light of the author\u27s spirit in this book. In the present article we will discuss how the character of Kunti has been recreated by Samaresh Basu in \u27Pritha\u27.
At the beginning of the story, before reaching the context of Kunti, the author undertakes a very realistic analysis of heaven-hell, Gods-demons, Samhita era-Puranic era, male-female relationship, marriage customs, child birth and the position of women in society. Then he explained the solitude, self-immolation and transition of Kunti from a feminist perspective.
The story of love-marriage-motherhood-heroism-restraint-pain-sacrifice of this remarkable female character of Mahabharata has been captured in a new way in the unique writing of Kalkoot. Inventing many thoughtful arguments the author tried to establish the father-son relationship between Yudhisthira-Vidura and Karna-Durbasha. How the author incarnated new contexts in the familiar story of Mahabharata and how he made it acceptable by arranging relevant arguments in favour of his new thoughts – this essay will try to elaborate these points

Etymology. This name “dinendra” is a patronym dedicated to Professor Dinendra Roychoudhury of Department of Zoology of University of Calcutta, who had encouraged the first author to carry out entomological research. Habitat. This species was collected from high mountainous cascades within the Neora Valley National Park of the Darjeeling District in West Bengal. The insects were found in steep, rocky areas flooded with splashing water, and appear adapted to the cold waters. A preference for rushing, high gradient upland streams has also been observed by the second author (DP) for another currently undescribed species of the Metrocoris compar species group collected in northern Vietnam, suggesting this habitat association may be typical of the group as a whole. Comparative notes. Metrocoris dinendrai sp. nov. belongs to Metrocoris compar group based on the structure of male fore femur, which is slender and slightly curved; the strongly curved male parameres; the elongate male pygophore which bears dense dark pilosity; and the laterally constricted female terminal abdominal sterna. This new species can be recognized within this group by the distinctive shape of male paramere, which has a a slightly expanded apex that is somewhat concave on its outer margin (Fig. 43); the structure of male endosomal sclerites (Fig. 44); and the female trochanter clothed with thick black bristles. Within the Metrocoris compar group, M. dinendrai seems most similar to M. pardus from the Malay Peninsula (Zettel, 2011a), but has the distal arm of the male paramere more slender and elongate, and the outer margin of the paramere apex concave rather than convex (compare Fig. 43 to Fig. 8 in Zettel, 2011a). The basal lobes on the male proctiger also are more angular than in M. pardus, whereas the internal sclerotization of the male endosoma is similar in both species.Published as part of Basu, Srimoyee, Polhemus, D.
