A SCIENTOMETRIC ANALYSIS OF LITERATURE OUTPUT IN THE JOUNAL SURVEY OF OPHTHALMOLOGY

Survey of Opthalmology is an international peer reviewed journal which publishes clinically oriented surveys in the field of ophthalmology. This study is an attempt to investigate and analyse the literature corpus published in the journal during the period 2014-2018. The data was obtained from PubMed. It was found that a total of 377 literatures were published during the period 2014-2018 by 1,520 authors. Two authorship pattern was the popular authorship pattern and degree of collaboration was 0.93. Majority of the first authors were from USA. The first authors from India had contributed 3.4% in the literature corpus. Most of the first authors from India were from LV Prasad Eye Institute and Dr. Rajendra Prasad Centre for Ophthalmic Sciences. Majority of the first authors from other countries were working in Massachusetts Eye and Ear Infirmary. The literature corpus was cited by 5,028 literatures. “Humans” was the most popular MeSH/keyword

Pit Slope Failure Problems in Goan Iron Ore Mines, Goa, India

The problem of open pit slope stability is a matter of concern when the mining operations go deeper followed by weak strata conditions. In Goa iron ore mines the problem of slope instability has been faced by several mines, after the on-set of monsoon. A review of case studies available on the subject demonstrates that the ground displacement, stress redistribution, effect of ground water, low strength characteristics of the slope forming materials played significant role for the cause of slope failures. Slope monitoring studies indicated that the mechanism of slope failures could be complex and dependent on failure pathways, where certain units fail first and it is followed by subsequent failures due to redistribution of stresses from the preceding zone. The results of several observations, laboratory testing of slope forming materials and monitoring of the slopes have lead to an awareness of various mechanisms of failure and the conditions under which they occur. In real world situations, the failure mechanisms are much more complex involving many other variables due to complexity within the geological materials. The paper addressed the design of practical pit slope angles in such type of weak strata conditions. The testing techniques for material properties enable weak zones to be identified and their relative strengths are accurately determined. Case study of a large Iron mine discussed in detail to demonstrate how deep mining can be carried out under difficult ground conditions

A retrospective study of 'non-compliant' patients in controlled clinical trials of short course chemotherapy

In a total of 2,332 pulmonary short-course chemotherapy studies conducted during 1975-1985, there were 60 ‘noncompliant’ patients who had received less than 75% of the prescribed treatment. A retrospective study was undertaken to find out the reasons for default in these patients since the Tuberculosis Research Centre has very stringent criteria of selection of patients for their, studies, an adequate system. of motivation of the patients and well organised infrastructure for retrieval of the defaulters. Unwillingness for treatment was stated as the reason for default by 20 patients and adverse reactions to the drugs by 16 patients. Other major reasons given were pressure of work (14 patients), frequent outstation visits (13) and migration (12)

A SCIENTOMETRIC ANALYSIS OF LITERATURE GROWTH IN ANTHRAX

Anthrax is an infectious disease which occurs regularly in southern Europe. It is also used as a weapon by a number of countries. This study is an attempt to investigate and analyze about the literature output on Anthrax. The aim of the present study was to identify literature growth over the period, literature distribution and authorship pattern. The data was obtained from PubMed using the keywords Anthrax”. It was found that a total of 1,955 published literatures for the period 2011-2018 in the field of Anthrax were contributed by 8,185 unique authors in 11 languages in 694 journals in 12 publication types. Ten and above authorship pattern contributed a higher percentage of literature while comparing with other authorship patterns and the total degree of collaboration was 0.94. First authors from USA have contributed around 44.6% of the total literature. Most of the literatures published in these years have citation count between 1-10. The literature published in the year 2011 have the highest citation counts. “Humans” was the more popular MeSH/keyword

Combining ability analysis and gene action of grain quality traits in rice (Oryza sativa L.) using line × tester analysis

In rice, twelve lines were crossed with five testers in a line × tester mating design and the resultant 60 hybrids along with their parents were evaluated for their combining ability effects for 15 grain quality traits. The results revealed that the ratio of GCA: SCA variances computed for all the fifteen grain quality traits showed the predominance of non-additive gene action. Among the lines, ADT (R) 47 showed significant desirable gca effects at 1% probability level (p = 0.01) for 11 grain quality traits viz., hulling percentage, milling percentage, head rice recovery percentage, kernel breadth, kernel breadth after cooking, breadth wise expansion ratio, gelatinization temperature, amylose content, gel consistency, water uptake and volume expansion ratio. Among the testers, Pusa 1460 showed significant desirable gca effects at 1% probability level (p = 0.01) for 10 grain quality traits viz., kernel length, kernel breadth, kernel length/breadth ratio, kernel length after cooking, kernel breadth after cooking, linear elongation ratio, gelatinization temperature, amylose content, water uptake and volume expansion ratio and hence they were adjudged as the best combiners for the improvement of the respective traits. Among the hybrids, the hybrids CO 47/Imp., Samba Mahsuri, ADT (R) 47/IRBB 21 and ADT (R) 46/IRBB 21 were identified as best hybrids for exploitation of grain quality traits since they revealed significant sca effects at 1% probability level (p = 0.01) for eight, eight and five grain quality traits, respectively

Effect of seed treatments on seed germination and seedling parameters in the F2 generation of mundu chilli (Capsicum annum L.)

Germination in chilli seeds is poor and the duration taken for the germination is long. In order to overcome their problems in germination, the seeds were to be subjected to seed treatments, So that the germination would be effective. The experiment was conducted at the Department of Vegetable Science HC & RI, Tami Nadu Agricultural University (TNAU), Periyakulam to study the effect of seed treatment views on the seedling character of mundu chilli. The experiment was laid in FCRD design with three replications. In this study, four F2 crosses viz., PKM CA 20 X PKM CA 08 (C1), PKM CA 32 X PKM CA 33 (C2), PKM CA 32 X PKM CA 20 (C3), PKM CA 38 X PKM CA 33 (C4) and seven treatments namely, Control (T0), Seed treatment with KNO3 0.5% (T1), Seed treatment GA3 50 ppm (T2), Seed treatment with NAA 100 ppm (T3), Hot water seed treatment at 60° C for 15 minutes (T4), Seed treatment with cow urine (T5), Seed treatment with Trichoderma viride (T6). Among all F2 crosses, PKM CA 38 X PKM CA 33 (C4) was most responsive to seed treatments in terms of the percent of seed germination and vigor index, followed by progeny PKM CA 32 X PKM CA 33 (C2) for root length and PKM CA 32 X PKM CA 20 (C3) for shoot length. The statistical analysis of the data showed the superiority of all the seed treatments over the control. The GA₃ treatment resulted in the maximum percentage of seed germination, root length, shoot length and vigor index followed by KNO3.    GA3 breaks the dormancy in the seeds and induces seed germination rapidly. Thus GA3 finds its way as the seed treatment agent in chilli.

Rifampicin-induced renal toxicity during retreatment of patients with pulmonary tuberculosis

Rifampicin is a crucial component of treatment regimens for tuberculosis and has been in use since the early 1970’s. It is usually considered safe. Rarely life-threatening complications like acute renal failure or acute thrombocytopaenia may manifest during treatment with rifampicin. In our experience at the Tuberculosis Research Centre of treating more than 8000 pulmonary and extrapulmonary tuberculosis patients with rifampicin-containing regimens over the last 30 years, we are reporting 3 cases of probably rifampicininduced acute renal failure. Despite extreme therapeutic safety of this drug the clinician must be aware of this rare complication, which if detected early is completely reversible
