No full textImpatiens kurichiarmalayana Saravanan & Kaliamoorthy, sp. nov. (Figure 2) Impatiens kurichiarmalayana is similar to I. mankulamensis K. M. P. Kumar, R. Jagad. & Nagaraj (2017: 281) and I. panduranganii K. M. P. Kumar, R. Jagad. & G. Prasad (2017: 285) in having common characters viz., rosulate leaves, umbellate cyme inflorescence, unequally bilobed wing petals and shorter basal lobes. But differs from I. mankulamensis by having ovate-lanceolate leaves (vs elliptic, lanceolate-oblanceolate in I. mankulamensis), lateral sepals white with dark purple tinges at the apex (vs white with brown tinges at tip in I. mankulamensis), dorsal petal white (vs pale purple in I. mankulamensis), presence of dorsal auricle (vs absence in I. mankulamensis) and absence of spur (vs present in I. mankulamensis); Impatiens kurichiarmalayana also differs from I. panduranganii by having white flowers with dark purple spot at the base of the wing petals (vs white with light purple dots in I. panduranganii), dorsal petal keeled at apex (vs not keeled in I. panduranganii), distal lobe spreading and broadly obovate (vs not spreading and shoe shaped in I. panduranganii), lower sepal white with yellow mark at middle and dark brown streaks horizontally (vs white with yellow tinges in I. panduranganii) (Table 2).

Capsules 0.7–1.0 × 0.2–0.3 cm, ellipsoid-clavate, greenish, glabrous; seeds minute, 0.1 cm long, sub-globose, pale yellow, with short white hairs scattered all over the surface. Phenology:—Flowering & fruiting: June–September. Ecology:—Growing on moss covered wet tree trunks in evergreen forests, in association with Bulbophyllum fischeri Seidenf. (1974: 202), Eria albiflora Rolfe (1893: 170) and Oberonia brunoniana Wight (1851: 1622), at an elevation of 1319 m. Conservation Status:— Impatiens kurichiarmalayana is only known from the type locality with about 10–15 mature individuals. The population is well conserved within the boundaries of protected forest areas. However, considering the lesser number of individuals in a single population size distributed in an area of hardly 0.3 km, the species described here is assessed as Critically Endangered (CE) by applying the criterion d (IUCN 2019). Etymology:—The specific epithet is named after the type locality, Kurichiarmala evergreen forests, Wayanad district, Kerala, India. Notes:— Impatiens kurichiarmalayana shows also similarities with I. travancorica Bedd. (1874: 29), in having a rosulate leaves, sub-umbellate raceme inflorescence, white flowers with dark purple patches near the base of the wing petals, sub-globose seeds with short hairs all over, but differs by its habit (Epiphytic tuberous herbs in I. kurichiarmalayana vs annual herbs in I. travancorica), size and shape of the lateral sepals (elliptic-oblong in I. kurichiarmalayana vs obliquely ovate in I. travancorica), dorsal petal (broadly ovate-orbicular in I. kurichiarmalayana vs cucullate in I. travancorica), dorsal auricle (present in I. kurichiarmalayana vs absent in I. travancorica) and spur (absent in I. kurichiarmalayana vs present in I. travancorica).Published as part of Saravanan, Thokuluva Santharam & Kaliamoorthy, Seventhilingam, 2022, Two new epiphytic species of Impatiens L.

Omega-3 fatty acids do not alter P-wave parameters in electrocardiogram or expression of atrial connexins in patients undergoing coronary artery bypass surgery.
No full textAims: We previously reported omega-3 polyunsaturated fatty acids (n-3PUFAs) supplementation does not reduce atrial fibrillation (AF) following coronary artery bypass graft (CABG) surgery. The aim of the present study is to evaluate the impact of n-3 PUFAs on electrocardiogram (ECG) atrial arrhythmic markers and compare with expression of gap-junction proteins, Connexins.Methods and results: Subset of clinical trial subjects with right atrial sampling during CABG surgery included. Twelve-lead ECG performed at recruitment and at surgery [after supplementation with n-3 PUFA (?1.8 g/day) or matched placebo] for ?14 days. Electrocardiograms analysed for maximum P-wave duration (P-max) and difference between P-max and minimum P-wave duration, P-wave dispersion (PWD). Right atrial specimens analysed for expression of Connexins 40 and 43 using real-time quantitative polymerase chain reaction (qPCR) and western blot. Serum levels of n-3 PUFA at baseline, at surgery, and atrial tissue levels at surgery collated from file. Postoperative AF was quantified by analysing data from stored continuous electrograms. A total of 61 patients (n-3 PUFA 34, Placebo 27) had ECG analysis and AF burden, of which 52 patients (26 in each group) had qPCR and 16 (8 in each group) had western blot analyses for Connexins 40 and 43. No difference between the two groups in ECG parameters or expression of Connexin 40 or 43. P-wave dispersion in the preoperative ECG independently predicted occurrence of AF following CABG surgery.Conclusions: Omega-3 polyunsaturated fatty acids supplementation does not alter pro-arrhythmic P-wave parameters in ECG or connexin expression in human atrium with no effect on the incidence of AF following CABG surgery
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
