Chronic Hypoxia Attenuates Ischemia-Reperfusion-Induced Increase in Pulmonary Vascular Resistance
No full textThis study explored the effect of chronic hypoxia on the elevation of pulmonary vascular resistance caused by ischemia-reperfusion (IR) in anesthetized rats. Experiments were separated into five parts. In Part 1, we examined the increase in left pulmonary vascular resistance (Rpl) after ischemia of the left lung and localized the major site for the increased resistance of the left pulmonary vasculature in both the normoxic and chronic hypoxia groups. Here, IR induced a significant increase in Rpl in the normoxic but not the chronic hypoxia group. This increased Rpl in the normoxic group was attributed to contraction of pulmonary arterial segments. Part 2 and Part 3 were focused on the changes in plasma nitrate/ nitrite (NOx) and thromboxane B-2( TxB(2)) levels. TxB(2) increased significantly in the normoxic group, whereas NOx increased significantly in the chronic hypoxia group, following ischemia. Indomethacin ( Part 4) prevented IR-induced increase in Rpl in the normoxic group, whereas the IR -induced increase in Rpl appeared in the chronic hypoxia group after N-G- nitro-L-arginine methyl ester treatment (Part 5). We conclude that IR elicited increases in the cyclooxygenase products such as TxB(2), which in turn caused an increase in Rpl. However, this increased Rpl was attenuated by elevated NOx in the chronic hypoxia group. (C) 2003 Elsevier Inc. All rights reserved

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Impact of Capsicum annuum L. cv Senise on cholesterol transporters
No full textDiet high in fatty acids increases plasma total cholesterol and lowdensity lipoprotein (LDL) concentration causing hyperlipidemia and atherosclerotic cardiovascular
disease, one of the major causes of death worldwide. Cholesterol homeostasis in the body is maintained mainly by de novo synthesis, intestinal absorption, and biliary
and fecal excretion [1].
Natural products could influence the lipid transporter expression and related diseases [2].
In the present work, the biological activity of Capsicum annuum L. cv Senise (Solanaceae), a sweet dried pepper of Basilicata region (Italy), was investigated in
HepG2 and Caco2 cells used as liver and intestine model, respectively. The extract showed no cytotoxic effect on both cell line after 24 and 48h evaluated by MTT
assay. Then, cells were treated with oleic acid (OA) in presence or absence of different concentrations of C. annuun extract (CAE) and the expression of lipid
transporters was evaluated by RTqPCR and western blotting. CAE promoted ABCA1 expression in OAtreated HepG2 cell line, a transporter involved in
cholesterol reuptake from peripheric tissues. CAE also affected lipid transport through intestinal barrier. Particularly, it drastically upregulated ABCA1, localized on
basolateral membrane of enterocytes, facilitating the efflux of cholesterol to circulation as constituent of HDL, together with ABCG5 and ABCG8, two ABC
transporters which promote efflux of cellular cholesterol to intestinal lumen and hepatobiliary secretion. In addition, CAE promoted the expression of LDL receptor in
Caco2 cells.
These results suggest as C. annuum cv Senise could be helpful in lowering plasma cholesterol levels and could play an important role in hyperlipidemia ranked as one of
the greatest risk factors contributing to prevalence and severity of coronary heart diseases.

Measurements of K S 0 - K L 0 asymmetries in the decays Λ c + → p K L , S 0 , p K L , S 0 π + π − and p K L , S 0 π 0
No full textAbstract Using e + e − annihilation data sets corresponding to an integrated luminosity of 4.5 fb −1, collected with the BESIII detector at center-of-mass energies between 4.600 and 4.699 GeV, we report the first measurements of the absolute branching fractions B Λ c + → p K L 0 = (1.67 ± 0.06 ± 0.04)%, B Λ c + → p K L 0 π + π − = (1.69 ± 0.10 ± 0.05)%, and B Λ c + → p K L 0 π 0 = (2.02 ± 0.13 ± 0.05)%, where the first uncertainties are statistical and the second systematic. Combining with the known branching fractions of Λ c + → p K S 0 , Λ c + → p K S 0 π + π − , and Λ c + → p K S 0 π 0 , we present the first measurements of the K S 0 - K L 0 asymmetries R Λ c + K S , L 0 X = B Λ c + → K S 0 X − B Λ c + → K L 0 X B Λ c + → K S 0 X + B Λ c + → K L 0 X in charmed baryon decays: R Λ c + p K S , L 0 = − 0.025 ± 0.031 , R Λ c + p K S , L 0 π + π − = − 0.027 ± 0.048 and R Λ c + p K S , L 0 π 0 = − 0.015 ± 0.046 . No significant asymmetries with statistical significance are observed

Head brown. Pronotum brown with black rectangular marking at base, nearly reaching anterior margin. Scutellum black. Elytra black with very narrow apical margin brown; each elytron with a pair of opposite commashaped reddish brown markings (Fig. 15n). Underside brown with prosternite and meso and metathoraces black. Legs brown with middle and hind coxae, hind femur black. Interocular distance slightly less than 1/2 head width. Innerocular margins almost parallel, slightly arcuate. Frons flat, punctation very fine, dense. Antenna 11segmented, proportions as illustrated (Fig. 15j). Maxillary palpus terminal segment with arcuate sides, distal side slightly oblique. Pronotum punctation slightly coarser than on head. Elytral punctation distincly coarser than head, pubescence arranged in strong Sform. Prosternal carinae distinctly convergent anteriorly. Postcoxal line of first abdominal sternite arcuate, complete, reaching about 3/4 length of sternite; enclosed area finely punctate, posterior 2/3 smooth. Fifth abdominal sternite hind margin truncate; sixth sternite apex nearly truncate. Genitalia: Sipho (Fig. 15a) relatively stout, basal 2/3 arcuate; siphonal capsule with stout outer process, slender inner process; siphonal apex simple, without appendix. Tegmen (Fig. 15b, c) stout; median piece of tegmen nearly parallelsided for basal 4/5, then narrowing apically with a teatshaped tip, in ventral aspect. In lateral aspect, median piece with tip slightly curved. Lateral lobes of tegmen distinctly shorter than median piece. Female. Similar to holotype except head black, pronotum black with anterior margin and corners brown, or with lateral margin brown; fifth abdominal sternite hind margin slightly arcuate, sixth sternite apex evenly arcuate. Genitalia as illustrated (Fig. 15k, l, m). Variation. Body length 2.00 to 2.10 mm, width 1.25 to 1.35 mm. Pronotum black with lateral sides brown. Elytron with brown or reddish brown irregular area around small black discal spot (Fig. 15o). Distribution. China (Yunnan). Type Series. Holotype: (Ƌ), Yunnan: Lijiang: Wenbishan (26.8 N, 100.2 E), 23IV1997, Yao D. et al. leg. (BAAF). Paratypes: (14 total, same data as holotype except) (3 ♀), (1 BAAF, 2 CAF); (1 ♀), 21IX1997, Yu G. leg.; (1 ♀), IV1996, Yao D. et al.; (1 Ƌ, 2 ♀), Baishuihe, 21IX1997, Yu G. collected on Picea likiangensis; (4 Ƌ, 2 ♀), CHINA: Yunnan: Lijiang: Wen Bi Shan, 20IV–l 2V1997, M. Montgomery leg. (USNM). Etymology. The specific name refers to the typical color pattern of the elytron. Remarks. This species resembles S. (P.) quadrillum Motschulsky and S. (P.) subvillosus (Goeze) in color pattern and body shape, but is quite different in male genitalia. The former is illustrated by Pang and Gordon (1986) as S. (P.) taiwanus Ohta (1929) and the latter by Gourreau (1974). The new species also resembles S. (P.) yemenensis (Kapur), but the latter has the lighter part of the elytron extending to the apex, and the outer siphonal process shorter and much narrower than the inner process. In the laboratory, adults fed on the hemlock woolly adelgid and laid eggs on hemlock twigs.Published as part of Yu, Guoyue, Montgomery, Michael E. & Yao, Defu, 2000, Lady Beetles (Coleoptera: Coccinellidae) From Chinese Hemlocks Infested With The Hemlock Woolly Adelgid, Adelges Tsugae Annand (Homoptera: Adelgidae), pp. 154-199 in The Coleopterists Bulletin 54 (2) on pages 177-178, DOI: 10.1649/0010-065X(2000)054[0154:LBCCFC]2.0.CO;
