Journal of Biological Sciences , 2001,
Abstract: Sewage sludge application had significantly effected all parameters of maize crop except germination percentage. Maximum Shoot length, Number of leaves per plant, Leaf area, Plant height, Root length, Shoot dry weight and Root dry weight of maize crop were obtained where sewage sludge was applied @ 10-30 ton ha-1. It was recommended that application of sewage sludge at the rate of 20 or 30 ton ha -1 will have favorable effect on the maize crop under the agro-climatic conditions of D.I.Khan.
Clinical Implications of Tumor Necrosis Factor-Alpha, Interleukin-6 and Resistin in Coronary Artery Disease  [PDF]
Qamar Javed
World Journal of Cardiovascular Diseases (WJCD) , 2014, DOI: 10.4236/wjcd.2014.49052
Abstract:

Tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) are involved in the progression of coronary artery disease (CAD). The cytokines’ levels are associated with the severity of CAD. We have recently reported on the association of resistin, a relatively novel cytokine with the pathogenesis of cardiovascular disease (CVD). Although the inflammatory cytokines’ impact on atherosclerosis is widely accepted, yet some controversy exists regarding the involvement of these factors in atherogenesis. The current review highlights the potential association of TNF-alpha, IL-6 and resistin SNPs (single nucleotide polymorphisms) with CAD. Molecular genetics data along with the intracellular signaling cascade mechanisms may have important clinical implications in the treatment of CAD.

Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.66055
Abstract: This knowledge of land surface temperature and its spatial variations within a city environment is of prime importance to the study of urban climate and human-environment interactions. Few studies have examined the influence of land use and terrain on the surface temperature effects of semi-arid mountainous urban areas. This study investigates the urban environment characterization and its effects on surface temperature using remote sensing. The methodologies adapted for this study are geometric and radiometric corrections of satellite data, extraction of land use/land cover and digital elevation model, estimation of vegetation density using Normalized Difference Vegetation Index (NDVI), and estimation of surface temperature and emissivity using temperature emissivity separation (TES) algorithm. Finally geospatial model and statistical techniques are used for assessing the overall impact of urban environmental characterization on urban climate of semi-arid region of Abha, Kingdom of Saudi Arabia. Herein, results reveal that the spatial distribution of surface temperature was affected by land use/land cover (LULC) and topography. The high dense built-up and commercial/industrial areas display higher surface temperature in comparison with surrounding lands. There is gradual decrease of LULC classes’ surface temperature with the increase in altitude. The cooling effect towards the surrounding urban built-up area is found increasing at the hill located vegetated area, the downward slope and valley terrain inside the recreational park. Therefore the spatial variation in surface temperature also reflected the effects of topography on LULC classes. Suitable mountainous land use utilization would help to expand the cooling effect. In the future, the outcomes of this study could be used to build environmentally sustainable urban planning suitable to semi-arid regions and to create practices that consider the local weather environment in urban planning.
Transthyretin—A Key Gene Involved in Regulating Learning and Memory in Brain, and Providing Neuroprotection in Alzheimer Disease via Neuronal Synthesis of Transthyretin Protein  [PDF]
Javed Iqbal
Journal of Behavioral and Brain Science (JBBS) , 2018, DOI: 10.4236/jbbs.2018.82005
Abstract: Transthyretin (TTR), a carrier protein present in the liver and choroid plexus of the brain, has been shown to be responsible for binding thyroid hormone thyroxin (T4) and retinol in plasma and cerebrospinal fluid (CSF). TTR aids in sequestering of beta-amyloid peptides Aβ deposition, and protects the brain from trauma, ischemic stroke and Alzheimer disease (AD). Accordingly, hippocampal gene expression of TTR plays a significant role in learning and memory as well as in simulation of spatial memory tasks. TTR via interacting with transcription factor CREB regulates this process and decreased expression leads to memory deficits. By different signaling pathways, like MAPK, AKT, and ERK via Src, TTR provides tropical support through megalin receptor by promoting neurite outgrowth and protecting the neurons from traumatic brain injury. TTR is also responsible for the transient rise in intracellular Ca2+ via NMDA receptor, playing a dominant role under excitotoxic conditions. In this review, we tried to shed light on how TTR is involved in maintaining normal cognitive processes, its role in learning and memory, under memory deficit conditions; by which mechanisms it promotes neurite outgrowth; and how it protects the brain from Alzheimer disease (AD).

E.g. if someone is looking at action movies it can recommend similar category or a category that the shopper is likely to be associated with. The mining of user's profile greatly enhances a person's shopping experience on modern online shops. The main purpose of this paper is solving the privacy and security issues.
Spatio-Temporal Land Cover Dynamics in Open Cast Coal Mine Area of Singrauli, M.P., India  [PDF]
Imran Khan, Akram Javed
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.46057
Abstract: Singrauli is an opencast coal mining area where large scale mining activities are going on continuously, land use/land cover studies are of vital importance to observe the changes in the land use/land cover. The present study utilizes multi-spectral/multi-temporal data of Indian Remote Sensing Satellite (IRS) LISS II geocoded (FCC) of 4th May 1993 and LISS III of 4th May 2010 for thematic mapping. Survey of India toposheet 63L/12 on scale 1:50,000 were used for preparation of base map which was overlaid on the FCC for land use/land cover mapping through visual interpretation. Visual interpretation of satellite imagery led to the identification of 15 land use/land cover categories such as dense forest, open forest, open scrub, plantation, cultivated land, uncultivated land, mining pit, overburden dumps, wasteland and settlement. The ground truth verification was carried out in key areas to rectify the errors in generated maps and then land use/land cover maps were finalized. The comparative analysis of land use/land cover shows that dense forest has been degraded to open forest, open scrubs and mining pits due to the expansion of mining activity. Open scrubs has increased, overburden dumps has increased, settlement has also increased, cultivated land has decreased and changed into uncultivated land and wasteland. It has also been observed that the plantation has been done on overburden dumps and residential colonies of NCL and NTPC. It has been identified that the main drivers which has increased the rate of change in land use/land cover are mainly coal mining activities and industrial expansion.
Identification of Artificial Recharge Sites in Manchi Basin, Eastern Rajasthan (India) Using Remote Sensing and GIS Techniques  [PDF]
Subah Rais, Akram Javed
Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.62017
Abstract:

The present study is an attempt to prepare a water resource development action plan for Manchi basin in Eastern Rajasthan (India) using remote sensing and GIS techniques. Satellite data have proven to be very useful for surface study, especially in the preparation of land use/land cover and geomorphological map. Morphometric parameters are analyzed to understand the basin characteristics and its influence on the water resources for instance bifurcation ratio indicates high surface run off and low recharge in SB-I, IV, V. Low drainage density ranges from 2.41 (SB-IV) to 2.99 (SB-V) km/km2, with an average of 2.72 km/km2 showing permeable strata, dense vegetation and low relief. Analysis of shape parameters i.e. elongation ratio and circularity ratio suggest that Manchi basin is elongated in shape. Whereas, slope, geology and geomorphological mapping is done to demarcate groundwater potential zones for future exploration in the study area. Slope is inversely proportional to infiltration. Therefore, sub-basin areas having gentle slope permits less runoff and more infiltration as in alluvial plains and vice versa where hills and ridges are present. The integrated study helps in designing suitable sites for constructing water harvesting structures. Check dams, percolation tanks and nala bund are proposed at 1st, 2nd or 3rd drainage orders at SB-I and SB-IV with ravenous land (open scrub), uncultivated land, open forest & exposed rock present. Nala bund & check dam are proposed at SB-II & SB-V whereas, at SB-III check dams & percolation tanks are proposed so as to conserve the natural resources present in the basin. Finally, the best feasible water harvesting structures have been proposed within the sub-basins area using remote sensing and GIS techniques.

Murid Javed, Essam Michael
Advances in Reproductive Sciences (ARSci) , 2015, DOI: 10.4236/arsci.2015.34008
Abstract: The number of reported new cancer cases is increasing every year. The probability of surviving cancer is high and is continually improving. The cancer treatment may induce ovarian or testicular failure by damaging ovarian follicles in females and spermatogonia in the males. Gonadal failure may affect all aspects of reproductive health, including pubertal development, hormone production, and sexual function in adult life. Therefore, the primary goal for cancer treatment is to ensure the highest possibility of cure and to maintain the reproductive health. The cancer patients should be provided with maximal chance to make an optimal decision without any significant impact and delay in cancer treatment. As a result of treatment innovations, the survival rates of young people have increased substantially; therefore, the need of fertility preservation has increased as well. The sperm cryopreservation and embryo cryopreservation have been standard methods of fertility preservation. Recently, the American Society for Reproductive Medicine has removed the experimental label from oocyte cryopreservation. However, other fertility preservation options including ovarian tissue and whole ovary cryopreservation and testicular tissue cryopreservation for pre-pubertal boys are still considered experimental. A coordinated approach by gynecologists, urologists, oncologists, pediatricians, surgeons, fertility specialists and counselors is required to make use of available fertility preservation options. Timely and complete information on the impact of cancer treatment on fertility and fertility preservation options should be presented to all patients when a cancer treatment is planned. The possibility of fertility preservation removes a huge concern and enables cancer patients to concentrate on their treatment and getting better. The purpose of this review is to present different options currently available to preserve fertility in men, women and adolescent children diagnosed with cancer and undergoing gonadotoxic therapy. All options are listed in two tables for quick reference. Most of the information is extracted from recent publications and presented in such a manner that it is valuable for cancer patients and professionals associated with fertility preservation.
