Screening of Sunflower Genotypes for Reaction to Alternaria Leaf Blight Disease across Multi-environments using Pooled Analysis
Sunflower (Helianthus annuus L.) is an oilseed crop with potential health benefits as a source of oil and dietary fiber. The productivity of sunflower is hampered by both biotic and abiotic stresses caused due to climate changes. So far, the available gene pool is having moderately resistant lines. In the present study, we evaluated two screening methods by artificially challenging the plants with the causative agent A. helianthi. Significant changes in disease severity have been observed across 160 pre-breeding lines of sunflower, including the susceptible check, Morden in three different seasons. Among the160 pre-breeding lines derived from a mutant population of sunflower cv. Morden, 6.25 and 5.63 % of lines showed less leaf blight disease incidence under in vivo and in vitro environments respectively. Moreover, 44.38 % of the sunflower pre breeding lines demonstrated field tolerance with disease severity in the scale of 5. The promising accessions evaluated in our studies by whole plant assay method and detached leaf technique includes KSFI 19, KSFI 24, KSFI 147, KSFI 56, KSFI 120, KSFI 88, KSFI 152, KSFI 51 and KSFI 115. Therefore, these sunflower lines, could be employed for introgression of resistance genes against leaf blight disease in sunflower cultivars through marker assisted breeding strategies
Cutaneous tumours of vascular origin: two rare entities
Skin and subcutaneous tissue are the most common location of benign and malignant vascular tumors. The benign or malignant nature of the lesion may not always be identified clinically because of the varying presentations. The histology of the lesion, especially in malignancies may not exhibit definite vascular pattern. In such cases, clinical presentation has to be correlated with histopathological picture as well as immunohistochemical characteristics to reach a specific diagnosis. Judicious use of immunohistochemical markers proves to be invaluable. Two rare cases of cutaneous vascular tumors which presented at our institution are cited, the diagnosis of which involved correlation of these modalities
Energy bands, conductance and thermoelectric power for ballistic electrons in a nanowire with spin-orbit interaction
We calculated the effects of spin-orbit interaction (SOI) on the energy
bands, ballistic conductance and the electron-diffusion thermoelectric power of
a nanowire by varying the temperature, electron density and width of the wire.
The potential barriers at the edges of the wire are assumed to be very high. A
consequence of the boundary conditions used in this model is determined by the
energy band structure, resulting in wider plateaus when the electron density is
increased due to larger energy-level separation as the higher subbands are
occupied by electrons. The nonlinear dependence of the transverse confinement
on position with respect to the well center excludes the "pole-like feature" in
the conductance which is obtained when a harmonic potential is employed for
confinement. At low temperature, the electron diffusion thermoelectric power
increases linearly with T but deviates from the linear behavior for large
values of T.Comment: Updated corrected version of the original submissio
Surgical treatment for cutaneous tumour in fish
A gold fish, Carassius auratus (L),
obtained from the Taraporevala Aquarium,
Bombay with cutaneous tumour
on the caudal peduncle and consequent difficulty in swimming, was
operated to remove the tumour growth
and relieve the fish. The fish was
observed to be normal when kept
under observation for a few days,
after surgery
Variations in concerns reported on the Patient Concerns Inventory (PCI) in head and neck cancer patients from different health settings across the world
Background: The aim was to collate and contrast patient concerns from a range of different head and neck cancer follow-up clinics around the world. Also, we sought to explore the relationship, if any, between responses to the patient concerns inventory (PCI) and overall quality of life (QOL). Methods: Nineteen units participated with intention of including 100 patients per site as close to a consecutive series as possible in order to minimize selection bias. Results: There were 2136 patients with a median total number of PCI items selected of 5 (2-10). “Fear of the cancer returning” (39%) and “dry mouth” (37%) were most common. Twenty-five percent (524) reported less than good QOL. Conclusion: There was considerable variation between units in the number of items selected and in overall QOL, even after allowing for case-mix variables. There was a strong progressive association between the number of PCI items and QOL

Effect of the spin-orbit interaction on the band structure and conductance of quasi-one-dimensional systems
We discuss the effect of the spin-orbit interaction on the band structure,
wave functions and low temperature conductance of long quasi-one-dimensional
electron systems patterned in two-dimensional electron gases (2DEG). Our model
for these systems consists of a linear (Rashba) potential confinement in the
direction perpendicular to the 2DEG and a parabolic confinement transverse to
the 2DEG. We find that these two terms can significantly affect the band
structure introducing a wave vector dependence to subband energies, producing
additional subband minima and inducing anticrossings between subbands. We
discuss the origin of these effects in the symmetries of the subband wave
functions.Comment: 15 pages including 14 figures; RevTeX; to appear in Phys.Rev.B (15

Movies and TV Influence Tobacco Use in India: Findings from a National Survey
Background: Exposure to mass media may impact the use of tobacco, a major source of illness and death in India. The objective is to test the association of self-reported tobacco smoking and chewing with frequency of use of four types of mass media: newspapers, radio, television, and movies. Methodology/Principal Findings: We analyzed data from a sex-stratified nationally-representative cross-sectional survey of 123,768 women and 74,068 men in India. All models controlled for wealth, education, caste, occupation, urbanicity, religion, marital status, and age. In fully-adjusted models, monthly cinema attendance is associated with increased smoking among women (relative risk [RR]: 1·55; 95% confidence interval [CI]: 1·04–2·31) and men (RR: 1·17; 95% CI: 1·12–1·23) and increased tobacco chewing among men (RR: 1·15; 95% CI: 1·11–1·20). Daily television and radio use is associated with higher likelihood of tobacco chewing among men and women, while daily newspaper use is related to lower likelihood of tobacco chewing among women. Conclusion/Significance: In India, exposure to visual mass media may contribute to increased tobacco consumption in men and women, while newspaper use may suppress the use of tobacco chewing in women. Future studies should investigate the role that different types of media content and media play in influencing other health behaviors
