Pearl millet [Pennisetum glaucum (L.) R. Br.] is an important staple food crop in the semiarid tropical regions of Asia and Africa. As part of a major initiative to improve its grain Fe and Zn densities, two sets of line × tester studies were conducted. Results showed that the underlying physiological processes determining the grain Fe and Zn densities were largely under additive genetic control, and Fe and Zn densities of the inbred lines per se and their general combining ability (GCA) were positively and highly significantly correlated. This would imply that recurrent selection can be effectively used to improve the breeding populations for grain Fe and Zn densities and that breeding lines selected for high Fe and Zn densities per se are more likely to include those with high GCA for these micronutrients. Lack of better‐parent heterosis indicated that to breed hybrids with high Fe and Zn densities would require high levels of these micronutrients in both parental lines. Highly significant and positive correlations between the Fe and Zn densities, between the GCA of Fe and Zn densities, and between the specific combining ability (SCA) of the Fe and Zn densities showed that simultaneous selection for both micronutrients is likely to be effective with respect to all these performance parameters. Consistency in the patterns of results across both sets of trials and across the environments for all the parameters implies that these results could be of wider application to the genetic improvement of Fe and Zn densities in pearl millet.
Traumatic diaphragmatic injury (DI) is a unique clinical entity that is usually occult and can easily be missed. Their delayed presentation can be due to the delayed rupture of the diaphragm or delayed detection of diaphragmatic rupture, making the accurate diagnosis of DI challenging to the trauma surgeons. An emergency laparotomy and thorough exploration followed by the repair of the defect is the gold standard for the management of these cases. We report a case of blunt DI in an elderly gentleman and present a comprehensive overview for the management of traumatic injuries of the diaphragm.
Context:Though some studies have described traumatic brain injuries in tertiary care, urban hospitals in India, very limited information is available from rural settings.Aims:To evaluate and describe the epidemiological and clinical characteristics of patients with traumatic brain injury and their clinical outcomes following admission to a rural, tertiary care teaching hospital in India.Settings and Design:Retrospective, cross-sectional, hospital-based study from January 2007 to December 2009.Materials and Methods:Epidemiological and clinical data from all patients with traumatic brain injury (TBI) admitted to the neurosurgery service of a rural hospital in district Wardha, Maharashtra, India, from 2007 to 2009 were analyzed. The medical records of all eligible patients were reviewed and data collected on age, sex, place of residence, Glasgow Coma Scale (GCS) score, mechanism of injury, severity of injury, concurrent injuries, length of hospital stay, computed tomography (CT) scan results, type of management, indication and type of surgical intervention, and outcome.Statistical Analysis:Data analysis was performed using STATA version 11.0.Results:The medical records of 1,926 eligible patients with TBI were analyzed. The median age of the study population was 31 years (range <1 year to 98 years). The majority of TBI cases occurred in persons aged 21 - 30 years (535 or 27.7%), and in males (1,363 or 70.76%). Most patients resided in nearby rural areas and the most frequent external cause of injury was motor vehicle crash (56.3%). The overall TBI-related mortality during the study period was 6.4%. From 2007 to 2009, TBI-related mortality significantly decreased (P < 0.01) during each year (2007: 8.9%, 2008: 8.5%, and 2009: 4.9%). This decrease in mortality could be due to access and availability of better health care facilities.Conclusions:Road traffic crashes are the leading cause of TBI in rural Maharashtra ffecting mainly young adult males. At least 10% of survivors had moderate or more severe TBI-related disabilities. Future research should include prospective, population based studies to better elucidate the incidence, prevalence, and economic impact of TBI in rural India.

F,.progenies from an 8 x 8 full diallel cross were studied for the inheritance of h i t yield and fruit and seed characters which are important in peanut (Arachis hypogaea L.) quality breeding. Substantial genetic variaton was observed for most characters among parents and crosses. Presence of significant heterotic crosses for several characters was an indication of genetic diversity present among the parental lines. Whereas fruit and seed traits were controlled largely by additive genetic effects and fruitdplant and fruit weighdplant by nonadditive genetic effects, for shelling percentage both were equally important. Estimates of general combining ability (gca) for ICGV 86564 was best for various fruit and seed traits. Other genotypes with good gca were ICG 2379 and ICG 3043 for h i t weight/plant and ICGV 87123 for shelling percentage. ICG 4906, ICG 7360, and ICGV 86564 showed significant maternal effects for various traits. Significant maternal interaction effect was evident for more than six traits in six crosses. A positive association among fruit and seed traits, and of fruit weighdplant with h i t number and with fruitheed lengfh and width should result in progenies with larger fruidseed size coupled with increased yields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
