RETRACTED: Activation of p38MAPK by repetitive low-grade oxidative stress leads to pro-survival effects
No full textThis article has been removed consistent with Elsevier Policy on Article Withdrawal. Please see http://www.elsevier.com/locate/withdrawalpolicy.The Publisher apologizes for any inconvenience this may cause.Reason: It was brought to our attention that loading control scans in two sets of figures among a total of 14 sets of figures presented in the article (BBA-MCR 1773:367-374, 2007) bear similarities. The first author, who was solely responsible for these experiments, regrets that due to inadequate archiving of the primary scans, dating back a number of years, he is unable to provide original unedited scans of the two sets of loading control blots at this point of time to conclusively establish the authenticity of the loading control scans. The authors therefore retract the article at this time. However, the actual experimental data, the conclusions and the resulting model are absolutely sound and the authors have reproduced most of the data. The authors fully intend to republish the data.Prosenjit SenPrabir Kumar ChakrabortySanghamitra Rah
Aspects of Authorship in journal special issues: An experience from DESIDOC Journal of Library and Information Technology
Get PDFIn the spirit of introspection, present study bibliometrically analyses 59 special issues comprising of 346 scholarly articles of DESIDOC Journal of Library and Information Science (DJLIT). To investigate the metrics of author inclusiveness of special issue
publications, present study examines authorship pattern, nature of authorship, trend and type of collaboration along with some demographic attributes like seniority, gender and professional rank/positions. Subsequent analysis focuses on prolific contributors,
degree of collaboration, collaborative index, geographical and institutional diversities. The study shows sustainable growth of special issues with domination of senior/ veteran authors from national research institutions around New Delhi. Dominance of single
authors (with nominal senior – senior collaboration) is attributed to less author diversity in this specialty. Author base is mostly endowed with blend of senior academia and LIS practitioners (having senior signing pattern) besides stray participations of specialized professionals. Study, therefore recognizes the fact that LIS special issue literatures are dominated by eminent and veteran authors, which eventually help to elevate scholar- ship, visibility and reputation of the source journal

Get PDFThis paper critically analyses 239 scholarly communications published in the inaugural five volumes of Journal of Informetrics (JOI) to examine growth of literature, types of communications, authorship pattern, collaboration trend, predominant research domains, etc. Subsequent analysis focuses on prolific contributors, degree of collaboration, and time-lag trend. Findings reveal that - publication output doubles over the study period as article publications increase considerably; though single-authored
contributions were significant (30 %), majority of contributions were collaborated by two-authors (36 %),
while average authorship accounts for 2.28 per communications. Degree of collaboration (DC) was
impressive (0.699) but not overwhelming as research collaborations has emanated from 199 higher learning institutions of 32 countries across the globe. Ranking of prolific contributors has shown Prof. Egghe on the top followed by L Bornmann; R Rousseau and L Leydesdoff. Result also shows upward trend of keyword usage with an average of 4.55 per items, of which h-index, citation analysis,
bibliometrics, g-index, etc, expectedly predominates. Scholarly nature of source journal has been further ascertained from increasing citations and reference usage trend. Moreover, growing hardness of the field has been attributed to JOI due to the increasing usage of tables and figures. Study also showed that the journal takes an average of about four month time to publish a manuscrip
Authorship Pattern and Research Collaboration of Journal of Informetrics
Get PDFThe study highlights the authorship pattern and research collaboration in the area of Informetrics based on 420 scholarly communications appeared in the Journal of Informetrics during 2007 to 2013. Study illustrates various significant aspects like –types and trends of authorship, author productivity, degree of collaboration,collaborative index, geographical diffusion and institutional diversification of authorship. Findings suggest tangible growth of Informetrics literature over the years with predominantly multi-authored contributions. Result also show that Informetrics research is unevenly scattered among 251 institutions from 38 countries around the globe
Scientometric evaluation of Sankhyá - the Indian Journal of Statistics
No full textThis paper critically analyses 199 peer-reviewed articles published in Sankhyā from 2003 to 2007. It examines authorship patterns, collaboration trends among authors, predominant areas of statistical research, and time lag in publications. Subsequent analysis focuses on prolific contributors, degree of collaboration, collaboration density, active sub-domains of statistics, and time lag trend. Findings reveal the following: (a) the number of articles reduced from 24.6% to 14.0% which conforms to the growth trend of statistical publications in India; (b) single-authored paper counts only 30%, the rest in collaboration either by two-authors (47%) or three-to-five authors (23%) and average authorship accounts for 1.96 per paper; (c) contributors of Sankhyā worked in highly collaborative manner and the degree of collaboration (CC=0.698) is quite significant; and (d) most of the bilateral and multilateral collaborations has emanated from 12 institutions of 5 different countries. A ranked list of prolific authors has been carried out using the fractional counting method. It is observed that author productivity is not in agreement with Lotka’s law, but productivity distribution data partially fits the law when the value of a approximated to 2.77 and the number of papers does not exceed two. Broad subject clusters, such as statistics (153) and probability theory (38) constituted about 96% of the contributed articles. Nonparametric inference (18%), parametric inference (15%), design of experiments (10%), and multivariate analysis (8%) are found to be active areas of research in statistics. The study shows an average time lag of fifteen months to publish an article, and a declining trend of time lags following second-degree polynomial type has been observed in this scholarly journal
Role of oral glutamine in alleviation and prevention of radiation-induced oral mucositis: A prospective randomized study
No full textBackground: Oral mucositis is the most frequently occurring painful and dose-limiting side-effect of radiation of the head and neck region. Few studies demonstrated that oral glutamine suspension may significantly reduce the duration and severity of objective oral mucositis during radiotherapy. Materials and Methods: A randomized, prospective single institutional case control study was performed between April 2012 and November 2012 comparing the influence of oral glutamine on radiation induced mucositis in head and neck malignancy patients. Seventy biopsy proven patients with head and neck cancer receiving primary or adjuvant radiation therapy were randomized to receive either oral glutamine suspension daily 2h before radiation in the study arm (10 g in 1000 ml of water) (n = 35) or nothing before radiation; control arm (n = 35). Results and Analysis: Total 32 patients (91.43%) in the glutamine arm and total 34 patients (97.15%) developed mucositis. Grade 3 mucositis (14.29%) and grade 4 mucositis (2.86%) in the study arm (who received oral glutamine) were significantly less (P = 0.02 and P = 0.04, respectively) in the glutamine arm. The mean duration of grade 3 or worse mucositis (grade 3 and grade 4) was significantly less (6.6 days vs. 9.2 days) in study arm with P < 0.001. Mean time of onset of mucositis was significantly delayed in patients who took glutamine in comparison to control arm with P < 0.001. Conclusion: Glutamine delays oral mucositis in the head neck cancer patients. Moreover, it reduces the frequency and duration of grade 3 and grade 4 mucositis
Phyto-chemical Standardization of Herbal Formulation (PMM3) for Blood Sugar Attenuating Actions in Streptozotocin induced Rats
Get PDFThe present study was intended to prepare herbal formulation, PMM3 using purified and modified parts of five common Indian herbs like, Trigonella foenum-graccum, Tinospora cordifolia, Scoparia dulcis, Adhatoda vasica and Cassia occidental. PMM3 was standardized using physico-chemical, phytochemical, UV-VIS spectral, HPTLC, AAS and GC methods. The phenolics and flavonoids contents were assessed. Anti-hyperglycaemic activities of PMM3 was evaluated on Streptozotocin induced (50mg/kg, i.v) diabetic rats. PMM3 (50-150 mg/kg, p.o) exhibited best potentiality in reducing blood glucose within 14 days treatment in comparison with Diabecon® (Himalaya, India) at the same dose. The preset observation identified formulation PMM3 for anti-hyperglycaemic effect
