Linkage mapping of QTLs for grain minerals (iron and zinc) and physio-morphological traits for development of mineral rich rice (Oryza sativa L.)

69-80In the present investigation, experiments were conducted to evaluate F3 and F4 populations derived from cross between PAU201 (high-yield) and Palman 579 (iron-rich) indica rice varieties for various physio-morphological traits and minerals (iron and zinc) content. Phenotypic correlation analysis showed no correlation between grain iron and zinc content in F3 and F4 population (s). A DNA fingerprint database of 33 PAU201 × Palman 579 derived F4 plants was prepared using 61 polymorphic SSR markers distributed on the entire genome of rice. The results of NTSYS-pc UPGMA tree cluster analysis and two and three dimensional principal component analysis (PCA) scaling showed scattering of the F4 population between the two distinct parent genotypes; but more inclined towards Palman 579. The SSR data was used to identify quantitative trait loci (QTL) for grain mineral content and physio-morphological traits. A total of 128 alleles and three new recombinant alleles were identified in F4 plants population. Composite interval mapping (CIM) analysis by WinQTL cartographer 2.5 revealed a total of six QTLs for mineral content (five for iron and one for zinc) in rice grains on chromosome 5, 6, 7, 9 and sixteen QTLs for various physio-morphological traits on chromosomes 2, 5, 7, 8, 9, 10 and 12. Linkage mapping of QTLs of minerals (iron and zinc) can greatly enhance the efficacy of breeding programs to improve mineral density in rice. The QTLs for minerals identified can successfully employed to improve the target traits through marker assisted selection

Multiple hepatic lesions in a case of isolated hepatic tuberculosis simulating metastases on 18F-FDG PET/CT imaging

Hepatic tuberculosis is an unusual form of extrapulmonary tuberculosis and constitutes less than 1% of all cases of tuberculosis. Imaging studies for hepatic tuberculosis are nonspecific and mimic primary or metastatic carcinoma. Here we present 18F-FDG PET/CT images of a 25-year-old male patient with isolated hepatic tuberculosis

Adamantinoma: A clinicopathological review and update

Adamantinoma is a primary low-grade, malignant bone tumor that is predominantly located in the mid-portion of the tibia. The etiology of the tumor is still a matter of debate. The initial symptoms of adamantinoma are often indolent and nonspecific and depend on location and extent of the disease. Histologically, classic adamantinoma is a biphasic tumor characterized by epithelial and osteofibrous components that may be intermingled with each other in various proportions and differentiating patterns. To assure the histological diagnosis, pathologists should employ immunohistochemistry for demonstrating the sometimes sparse epithelial cell nests when the radiological features are suggestive of adamantinoma. There is paucity of compiled data over adamantinoma in the literature, hence authors tried to make a comprehensive review which must be of use to beginners and trained pathologists. Our objective is to further define the clinicoradiologic features and pathologic spectra of adamantinoma

In Vitro Anti Bacterial Potential of Different Extracts of Tagetes Erecta and Tagetes Patula

The antimicrobial activity of cold aqueous, hot aqueous and methanol extracts of Tagetes erecta and Tagetes patula flowers was evaluated by agar well diffusion method against ten different pathogenic species of Gram-negative bacteria viz.,  Escherichia coli, Proteus vulgaris, Proteus mirabilis, Aeromonas sobria, Aeromonas hydrophila, Plesiomonas shigelloides, Salmonella enterica serotype Typhi, Salmonella enterica serotype Typhimurium, Salmonella enterica serotype Aboni and Salmonella enterica serotype Enteritidis, four different pathogenic species of Gram-positive bacteria such as Bacillus subtilis, Bacillus cereus, Bacillus circulans and Staphylococcus aureus. Methanol extract of Tagetes erecta at 40 mg/ml concentration was found to have better inhibitory activity when compared to cold and hot aqueous extracts, which were evident through the increased zones of inhibition against Gram-negative and Gram-positive bacteria. Methanol extract of Tagetes erecta showed highest inhibition zone of 26 mm against Aeromonas sorbia, Aeromonas hydrophila, Staphylococcus aureus (MTCC7405) and Staphylococcus aureus (clinical isolate), while lowest inhibition zone of 12 mm with Bacillus subtilis. Similarly, hot aqueous extracts of Tagetes patula had better activity as compare to cold aqueous extract and methanol extract at 40mg/ml concentration. It had highest and lowest zone of inhibition with Proteus vulgaris OX19 (30 mm) and Staphylococcus aureus (clinical iolate) (13 mm) respectively. Minimal inhibitory concentrations (MICs) were between concentrations of 20 - 160 mg/ml with aqueous or methanol extracts of Tagetes erecta and Tagetes patula flowers for most of the tested bacteria. Results of antimicrobial activity of extracts indicate that they possess potential broad spectrum antibacterial activity. Keywords: Tagetes flower extracts, antibacterial activit

pyParaOcean: A System for Visual Analysis of Ocean Data

Visual analysis is well adopted within the field of oceanography for the analysis of model simulations, detection of different phenomena and events, and tracking of dynamic processes. With increasing data sizes and the availability of multivariate dynamic data, there is a growing need for scalable and extensible tools for visualization and interactive exploration. We describe pyParaOcean, a visualization system that supports several tasks routinely used in the visual analysis of ocean data. The system is available as a plugin to Paraview and is hence able to leverage its distributed computing capabilities and its rich set of generic analysis and visualization functionalities. pyParaOcean provides modules to support different visual analysis tasks specific to ocean data, such as eddy identification and salinity movement tracking. These modules are available as Paraview filters and this seamless integration results in a system that is easy to install and use. A case study on the Bay of Bengal illustrates the utility of the system for the study of ocean phenomena and processes.Comment: 8 pages, EnvirVis202

A comparative study between ProSeal laryngeal mask airway and endotracheal tube for ease of insertion and haemodynamic changes in patients undergoing laparoscopic cholecystectomy under general anaesthesia

Background: The endotracheal tube is considered a gold standard for providing a safe and effective glottic seal, especially for laparoscopic procedures under general anaesthesia. However, haemodynamic pressor responses associated with its use might be detrimental. The ProSeal LMA minimizes this response without compromising the airway with lesser incidence of complications. The aim of this study was to compare ProSeal LMA and Endotracheal tube with respect to intra-operative haemodynamic responses and ease of insertion of device and nasogastric tube in patients undergoing laparoscopic surgeries under general anaesthesia.Methods: This prospective randomized study was conducted on sixty patients, aged 20-60 years; of ASA grade 1 or 2, 30 in each group, posted for laparoscopic cholecystectomy under general anaesthesia. After induction with propofol and neuromuscular blockade with rocuronium, PLMA or ETT was inserted. The haemodynamic responses and insertion time of device and nasogastric tube were noted. Postoperative complications, if any were also noted.Results: The mean time of insertion of PLMA was 37.40±16.09 seconds and for intubation (ETT) was 31.17±20.89 seconds which was statistically not significant (P >0.05). The mean time of insertion of nasogastric tube was 18.84±6.84 seconds in PLMA group and 73.00±71.06 seconds in the ETT group which was highly significant, (P 0.05).Conclusions: ProSeal LMA proved to be a suitable alternative to endotracheal tube for airway management with stable haemodynamics in patients undergoing laparoscopic cholecystectomy under general anaesthesia
