infant brain development. State-of-the-art methods for adult brain MRI segmentation are not applicable to the
neonatal brain, due to large differences in structure and tissue properties between newborn and adult brains.
Existing newborn brain MRI segmentation methods either rely on manual interaction or require the use of atlases or
templates, which unavoidably introduces a bias of the results towards the population that was used to derive the
atlases. We propose a different approach for the segmentation of neonatal brain MRI, based on the infusion of highlevel
brain morphology knowledge, regarding relative tissue location, connectivity and structure. Our method does
not require manual interaction, or the use of an atlas, and the generality of its priors makes it applicable to different
neonatal populations, while avoiding atlas-related bias. The proposed algorithm segments the brain both globally
(intracranial cavity, cerebellum, brainstem and the two hemispheres) and at tissue level (cortical and subcortical
gray matter, myelinated and unmyelinated white matter, and cerebrospinal fluid). We validate our algorithm
through visual inspection by medical experts, as well as by quantitative comparisons that demonstrate good
agreement with expert manual segmentations. The algorithm's robustness is verified by testing on variable quality
images acquired on different machines, and on subjects with variable anatomy (enlarged ventricles, preterm- vs.
term-born). | | | | Author Profile | Full-Text PDF | |
| | | 15 | Scope of pre-breeding in mulberry crop improvement - A review | | By : D. Mohan Ram Rao, K. Jhansilakshmi, P. Saraswathi,A. Ananda Rao, S. R. Ramesh, M. M. Borpuzari And A. Manjula | | Abstract : Mulberry leaves are the only source of food for silkworm (Bombyx mori L.). Several improved mulberry
varieties were developed during the last few decades for expansion of sericulture. Most of the varieties developed
are from the same genetic background, this has lead to narrow genetic base and hence vulnerable to biotic and
abiotic stress. To avoid this situation, it is essential to enhance the genetic variability in the germplasm collections
and this is possible through pre-breeding, further the genetically enhanced germplasm will be used in the breeding
programme for cultivar development. Pre-breeding deals with the germplasm enhancement and conventional
breeding refers to cultivar development. In several crops, pre-breeding lines were developed with specific traits, by
using wild / exotic (unadapted) germplasm and the improved prebred material were used in breeding programme for
the improvement of cultivated mulberry varieties. Efforts on prebreeding in mulberry revealed the possibilities of
producing F1 hybrids with some of the characters of wild (unadapted) species. Further, to initiate pre-breeding in a
large scale in order to develop region specific or stress resistant varieties, it is most essential to have detail
information on three important aspects viz., mulberry germplasm collections, knowledge on different morus
species and selection of parents. This paper provides a detail information about collection, conservation, evaluation
and maintenance of mulberry germplasm; origin distribution and characteristics features of different morus species;
use of wild /exotic germplasm in different crops including mulberry; constraints in use of exotic germplasm; seed
setting percentage of different combination of morus species; use of molecular marker for assessing the genetic
relationship of different morus species; purpose and methods of prebreeding; prebreeding strategy in mulberry and
need of prebreeding for mulberry crop improvement. | | | | Author Profile | Full-Text PDF | |
| | | 16 | Trichosanthes tricuspidata Methanol and Petroleum ether extract effect on Culex | | By : Sonwalkar R.P And Kadam P.S | | Abstract : Trichosanthes tricuspidata Climbed frequently up to a height of 10m, belonging to family cucurbitaceae.
It is most valuable medicinally significant as in ayurvedic medicines the fruits play very important role, they are
used in the treatment of asthma, ozoena, and ear-ache. Dispending medicinally uses, our study have been found that
this climber has mosquito repellent activities. To determine repellant activities methanol and petroleum ether fruit
extract of T. tricuspidata was used against the larvae of Culex quinquefasciatus. The Larval mortality was observed
after 24h exposure and highest larval mortality was found in methanol fruit extract of T. tricuspidata | | | | Author Profile | Full-Text PDF | |

Bala Chennaiah1 A. M. Dayal | | Abstract : A study was conducted to assess the ground water quality in Uppal Industrial area of Hyderabad, India.
The study consists of the determination of physico-chemical properties, trace metals, heavy metals, rare earth
elements (REE) and microbiological quality of drinking water. The data showed the variation of the investigated
parameters in samples as follows: pH 6.83 to 7.75, EC 1095 to 7290μS/cm and TDS 734 to 4884 ppm. The physicochemical
properties such as EC and TDS in ground water samples of the study area exceed the permissible limits of
WHO (2004). The water samples were analyzed for 27 elements (Li, Be, B, Na, Mg, Al, Si, K, Ca, V, Cr, Mn, Fe, Ni,
Co, Cu, Zn, As, Se, Rb, Sr, Mo, Ag, Cd, Sb, Ba and Pb) using Inductively Coupled Plasma-Mass Spectrometry (ICPMS).
The concentrations ranged between for B (0.25 to 0.70 mg/L), Na (105.65 to 845.53 mg/L), Mg (23.24 to
195.16 mg/L), Al (0.06 to 0.18 mg/L), K (5.15 to 66.22 mg/L), Ca (105.68 to 547.49 mg/L), Fe (0.38 to 1.15 mg/L),
Cu (0.02 to 0.36 mg/L), Ni (0.05 to 0.42 mg/L), Cr (0.06 to 0.08 mg/L), Mn (0.02 to 2.17 mg/L) and Pb (0.01 to 0.14
mg/L). Overall, decreasing metal concentration order was: Na>Ca>Mg>K>Mn>Fe>Co>B>Ni>Cu>Al>Pb.
The concentrations of B, Na, Al, Mg, K, Ca, Cr, Mn, Fe, Ni, Cu, and Pb exceed the permissible limits of the World
Health Organization (WHO) for drinking water quality, whereas Li, Be, Ba, Si, V, Co, As, Se, Rb, Sr, Mo, Ag, Cd, and
Sb concentrations are within the permissible limits. The microbiological quality of water was tested using Most
Probable Number (MPN) and Thermo tolerant Coliform bacteria (TTC) methods. The total numbers of Coliform
bacteria in water samples were found to be of order of 9 to 460 MPN index/100 ml. TTC tested positive for coliform
bacteria at 44.2°C. The total coliform bacteria in the ground water samples were also found to exceed the
permissible limits. From the above results it is clearly evident that the ground water of the study area is
contaminated due to the industrial effluents and also from sewage contamination and the overall water quality was
found unsatisfactory for drinking purposes.Thus, water quality indicates that pollution of the water is increasing
alarmingly and that it has created serious threat to human health. | | | | Author Profile | Full-Text PDF | |
| | | 18 | Seasonal Variations In The Physico-chemical Parameters Of Pindavani Pond Of Central India | | By : N.V. Harney , A.A. Dhamani And R.J. Andrew | | Abstract : The seasonal variations in the physico-chemical parameters of Pindavani pond of central India, located
near Bhadrawati town of Chandrapur district of Maharashtra state was studied from October 2005 to September
2007. The parameters that were determined included temperature, pH, transparency, conductivity, dissolved
oxygen (DO), free carbon dioxide, alkalinity, hardness (calcium, magnesium), chloride, biological oxygen demand
(BOD), chemical oxygen demand (COD), and phosphate, sulphate and nitrate concentrations.
In the present investigation, the atmospheric temperature was found to be higher than the water
temperature and as expected, the maximum water temperature was recorded during the summer and minimum
during the winter season. Maximum transparency was recorded during winter and minimum during the monsoon
season, while maximum conductivity, pH and BOD were recorded during summer and minimum during the
monsoon season. Free carbon dioxide, total hardness, calcium and magnesium hardness, chemical oxygen
demand and phosphate and sulphate concentration were maximum during summers and minimum during the
winter season while DO and chloride showed the maximum levels during the summer and minimum during the
monsoon season. Alkalinity and nitrate showed maximum level during the monsoon and minimum during the winter
season. The comparative higher value of conductivity, total alkalinity, chloride, phosphate and nitrate in Pindavani
pond indicates its contaminated status. | | | | Author Profile | Full-Text PDF | |
