A study on patients treated with interlock nailing in the forearm fracture bones
Background: Fractures involving the bones of the forearm present unique problems not encountered with fractures of other long bones and may significantly affect the function of the upper limb. The purpose of the present study was to evaluate the functional outcome of patients treated with interlock nailing in the fracture forearm bones.Methods: Thirty two patients included after their consent. With the patient supine on a radiolucent table, and under general or regional anesthesia the extremity was prepared and the surgery was performed using a standard procedure. If secure rigid fixation is achieved forearm POP splint is applied and kept in place for 2 weeks, thereafter a removable sugar-tong orthosis is worn until bridging callus is present, and the orthosis is removed frequently for exercise.Results: The average age of the patients was 38.90 years. The major mode of injury was RTA (59.09%) followed by assault (36.36%). 41% of patients were operated within week of injury, only three patients were operated after a week and one patient after 3 weeks. More than half of patients had closed fractures and rest was open fractures, of which Gustilo Anderson type II were in majority. In 3/5 of patients locking at nondriving end was not done cause of stable fixation. There was statistically significant difference in the surgical time (P <0.05) and duration of postoperative immobilization differed statistically significantly (P <0.001) between the group of patients in whom locking was done and not done. Conclusions: Advantages of Interlocking nail are high rate of bony consolidation along with minimized surgical approaches, cosmetically better suited and little risk of refracture after removal of the implant
Evaluation of fungal pathogens, Fusarium semitectum Berk. and Ravenel and Hirsutella thompsonii Fisher against red spider mite, Tetranychus neocaledoni-cus (Andre) of okra under laboratory and greenhouse conditions
Efficacy of fungal pathogens, Fusarium semitectum Berk. and Ravenel and Hirsutella thompsonii Fisher was evaluated against red spider mite, Tetranychus neocaledonicus (Andre) of okra under laboratory and greenhouse conditions. Among the treatments evaluated under laboratory conditions, the highest mortality of 78.20 and 88.34 percent adults and immatures, respectively was recorded at 2.10 x 109 spores per ml of F. semitectum, whereas it was 82.05 and 92.31 per cent adults and immatures, respectively in case of H. thompsonii at 4.60 x 108 spores per ml. Among the twelve treatments evaluated under greenhouse conditions, H. thompsonii 4.60 x 108 spores per ml, F. semitectum 2.10 x 109 spores per ml + H. thompsonii 4.60 x 108 spores per ml, H. thompsonii 4.60 x 108 spores per ml + dicofol 0.025% and F. semitectum 2.10 x 109 spores per ml + H. thompsonii 4.60 x 108 spores per ml + dicofol 0.025% were found to be on par with each other with a cumulative percent mortality of 81.20, 81.48, 81.21 and 82.59 percent, respectively. By testing the field efficacy of F. semitectum and H. thompsonii against T. neocaledonicus, these fungal pathogens can be used as potential biocontrol agents for the sustainable management of mites on okra. Hence the present study evaluates the potentiality of F. semitectum for the management of T. neocaledonicus by comparing with the well-known acaricidal fungus, H. thompsonii
Evaluation of Novel Gerbera (Gerbera jamesonii Bolus ex. Hooker F.) Hybrids for Flower Quality Traits under Naturally-Ventilated Polyhouse
The present study was carried out to evaluate performance of two gerbera hybrids IIHR 3-34 and IIHR 8-45 along with their parents and check, for flower quality traits under naturally-ventilated polyhouse in Randomized Block Design, in the years 2014-15 and 2015-16. Both the hybrids had been developed through the half-sib method of breeding with IIHR-3 and IIHR-1, respectively, as parents. Data for the two years were pooled and analyzed statistically. Significant differences were observed in the quality traits studied. In the case of both hybrids IIHR 3-34 and IIHR 8-45, most of the quantitative traits were found to be on par with the check variety, Elite. They had novel flower colour (68D as per RHS Colour Chart), Red Purple Group (IIHR 3-34) and 50A Red Group (IIHR 8-45), with double type of flowers. These are suitable for cut-flower and flower arrangement purposes. These hybrids will prove useful for developing more gerbera hybrids with novel traits
Effect of Temperature and Period of Storage on Breaking Dormancy in Gladiolus (Gladiolus grandiflorus Hort.) Corms
An experiment was conducted in 2010-2011 at Indian Institute of Horticultural Research, Bengaluru, on three gladiolus cultivars viz., 'Arka Amar', 'Darshan' and 'Kum Kum' to study effects of storage temperature (4°C and room temperature 27±2°C) and length of storage (50, 70 and 90 days) on dormancy of corms. Cv. 'Kum Kum' registered minimum number of days for sprouting (42.71 days), spike emergence (116 days) and days to opening of first floret (128 days). Corms stored at 4°C resulted in lowest number of days for-sprouting (45.24 days), days to spike emergence (114.63 days) and days to opening of first floret (126.60 days) and resulted in highest sprouting percentage (58.7%). Interaction effects revealed that cv. 'Kum Kum' stored at 4°C for 90 days after harvest took minimum number of days to sprouting (25.07 days), days to spike emergence (90.38 days) and days to opening of first floret (102.38 days) resulting in 100% sprouting
Genetic Variability for Quantitative Traits in China Aster [Callistephus chinensis (L.) Nees]
A field study was conducted to estimate genetic variability, heritability and genetic advance in 20 genotypes of China aster for 15 traits during the year 2012-13 in Randomized Complete Block Design, with three replications. Results revealed that the magnitude of phenotypic co-efficient of variation (PCV) was higher than genotypic co-efficient of variation (GCV) for all the traits studied. Narrow differences between GCV and PCV were recorded in all the characters except flowering duration, vase-life and shelf-life, indicating little environmental influence on expression of these characters. High (>20%) GCV and PCV were recorded for plant height, number of branches and leaves per plant, flower diameter, number of ray and disc florets/flower head, stalk length, and, number and weight of flowers/plant. Heritability estimates ranged from 28.30% (flowering duration) to 99.54% (flower diameter). High heritability (<60%) was observed for all the traits except flowering duration. High heritability, coupled with high genetic advance as per cent mean, was recorded for flower diameter, stalk-length, number of branches/plant, weight of flowers/plant, days to first flower opening, days to 50 per cent flowering, plant height, number of leaves/plant, number of ray and disc florets/flower head, number of flowers/plant, indicating a possible role of additive gene action. Thus, these traits can be improved through selection and breeding

218-222The cross sections have been estimated for the Nuclear reactions 92Mo(n,α)89Zr and 97Mo(n,p)97Nb produced in Purnima neutron generator at neutron energy of 13.52±0.0045 MeV using activation analysis and off-line γ -ray spectrometric techniques. 27Al(n,α)24Na has been used as a monitor reaction. The covariance analysis for these cross sections has been carried out by taking into consideration of partial uncertainties of different attributes and correlations between the attributes. The cross section values of the present study have been compared with EXFOR, ENDF data of various libraries and theoretical data of TALYS-1.8 code
Snake Genome Sequencing : Results and Future Prospects
Snake genome sequencing is in its infancy-very much behind the progress made in sequencing the genomes of humans, model organisms and pathogens relevant to biomedical research, and agricultural species. We provide here an overview of some of the snake genome projects in progress, and discuss the biological findings, with special emphasis on toxinology, from the small number of draft snake genomes already published. We discuss the future of snake genomics, pointing out that new sequencing technologies will help overcome the problem of repetitive sequences in assembling snake genomes. Genome sequences are also likely to be valuable in examining the clustering of toxin genes on the chromosomes, in designing recombinant antivenoms and in studying the epigenetic regulation of toxin gene expression.Peer reviewe
Enteral lactoferrin supplementation for very preterm infants: a randomised placebo-controlled trial
Background
Infections acquired in hospital are an important cause of morbidity and mortality in very preterm infants. Several small trials have suggested that supplementing the enteral diet of very preterm infants with lactoferrin, an antimicrobial protein processed from cow's milk, prevents infections and associated complications. The aim of this large randomised controlled trial was to collect data to enhance the validity and applicability of the evidence from previous trials to inform practice.
Methods
In this randomised placebo-controlled trial, we recruited very preterm infants born before 32 weeks' gestation in 37 UK hospitals and younger than 72 h at randomisation. Exclusion criteria were presence of a severe congenital anomaly, anticipated enteral fasting for longer than 14 days, or no realistic prospect of survival. Eligible infants were randomly assigned (1:1) to receive either enteral bovine lactoferrin (150 mg/kg per day; maximum 300 mg/day; lactoferrin group) or sucrose (same dose; control group) once daily until 34 weeks' postmenstrual age. Web-based randomisation minimised for recruitment site, gestation (completed weeks), sex, and single versus multifetal pregnancy. Parents, caregivers, and outcome assessors were unaware of group assignment. The primary outcome was microbiologically confirmed or clinically suspected late-onset infection (occurring >72 h after birth), which was assessed in all participants for whom primary outcome data was available by calculating the relative risk ratio with 95% CI between the two groups. The trial is registered with the International Standard Randomised Controlled Trial Number 88261002.
Findings
We recruited 2203 participants between May 7, 2014, and Sept 28, 2017, of whom 1099 were assigned to the lactoferrin group and 1104 to the control group. Four infants had consent withdrawn or unconfirmed, leaving 1098 infants in the lactoferrin group and 1101 in the sucrose group. Primary outcome data for 2182 infants (1093 [99·5%] of 1098 in the lactoferrin group and 1089 [99·0] of 1101 in the control group) were available for inclusion in the modified intention-to-treat analyses. 316 (29%) of 1093 infants in the intervention group acquired a late-onset infection versus 334 (31%) of 1089 in the control group. The risk ratio adjusted for minimisation factors was 0·95 (95% CI 0·86–1·04; p=0·233). During the trial there were 16 serious adverse events for infants in the lactoferrin group and 10 for infants in the control group. Two events in the lactoferrin group (one case of blood in stool and one death after intestinal perforation) were assessed as being possibly related to the trial intervention.
Interpretation
Enteral supplementation with bovine lactoferrin does not reduce the risk of late-onset infection in very preterm infants. These data do not support its routine use to prevent late-onset infection and associated morbidity or mortality in very preterm infants.
