Toxic optic neuropathy
Sharma Pradeep,Sharma Reena
Indian Journal of Ophthalmology , 2011,
Abstract: Toxic optic neuropathy (TON) is a disease entity which is not only underdiagnosed, but also often diagnosed at a stage when recovery of vision is not possible. This article gives an overview of common causes, clinical features, and management of TON.
An in silico Analysis of Upstream Regulatory Modules (URMs) of Tapetum Specific Genes to Identify Regulatory cis-Elements and Transcription Factors  [PDF]
Preeti Apurve Sharma, Pradeep Kumar Burma
American Journal of Molecular Biology (AJMB) , 2018, DOI: 10.4236/ajmb.2018.81002
Abstract: The present work presents an iin silicoi analysis of Upstream Regulatory Modules (URMs) of genes expressed in tapetum specific manner in dicotyledon and monocotyledon plants. In the current analysis, we identified several motifs conserved in these URMs of which ten were observed to be part of known icisi-elements using tools and databases like MEME, PLACE, MAST and TFSEARCH. We also identified that binding sites for two transcription factors, DOF and WRKY71 were found to be present in majority of the URMs.
Horizontal lang two-pencil test as a screening test for stereopsis and binocularity
Nongpiur Monisha,Sharma Pradeep
Indian Journal of Ophthalmology , 2010,
Abstract: Purpose: To assess the horizontal Lang two-pencil test as a bedside test to detect gross stereopsis. Materials and Methods: Eighty-four strabismic subjects divided into two groups based on the amount of deviation, and 40 normal subjects were studied. Sensory status examination including binocularity and stereopsis were evaluated with Bagolini, Titmus test and the Netherlands organisation for applied scientific research (TNO), Randot, synoptophore and horizontal Lang two-pencil test. Results: The subjects in the group with smaller deviation showed better performance on all the four stereo tests and over 90% demonstrated presence of fusion. When compared to TNO and Randot for determining presence of stereopsis, the horizontal Lang two-pencil test demonstrated sensitivity of 100% and 83.9%, specificity of 77.8% and 73.7%, and negative predictive value of 100% and 100% respectively. It also showed 100% specificity as a test for binocularity when compared with the Bagolini striated glass test. Conclusion: Horizontal Lang two-pencil test, an easily performed test with a high sensitivity and negative predictive value can be used as a screening test to detect gross stereopsis and binocularity.
Effect of aniseikonia on fusion
Sharma Pradeep,Prakash Prem
Indian Journal of Ophthalmology , 1991,
Abstract: Physiological aniseikonia is the basis of stereopsis but beyond certain limits it becomes an obstacle to fusion. It is not well established as to how much aniseikonia can be tolerated by the fusional mechanism. Different tests under different testing conditions have given a wide range of variation. On the synoptophore we had observed tolerance upto 35% aniseikonia in some cases. Under more physiological conditions on a polaroid dissociation stereoprojector we observed lesser baseline fusional vergences but tolerance in about 70% of the cases upto 30% aniseikonia while 25% could tolerate even 35% aniseikonia. However we realise that these indicate the maximal potential and not the symptom free tolerable limits.

In Vitro Studies on Sida Cordifolia Linn for Anthelmintic and Antioxidant Properties  [PDF]

Chinese Medicine (CM) , 2011, DOI: 10.4236/cm.2011.22009
Abstract: The present study was undertaken to evaluate in-vitro antioxidant and anthelmintic activity of ethanolic and aqueous extract from whole plant Sida cordifolia Linn (Malvaceae). The antioxidant activities are evaluated by various antioxidant assays like α, α-Diphenyl-β-picrylhydrazyl (DPPH) free radical scavenging, total reducing power, nitric oxide scavenging and hydrogen peroxide scavenging. The various antioxidant activities were compared to standard antioxidants such as ascorbic acid. The antioxidant activity of ethanolic extract is almost quantitatively equivalent to that of the standards used, ascorbic acid. The further anthelmintic activity of whole plant is investigated through using Indian earthworm (Pheretima posthuma) showed that it is one of the most important local medicinal plants both for ritual and ethnomedical practices. Various concentrations of ethanol and aqueous extract (10, 20, 30, 40 mg/ml) of whole plant of Sida cordifolia Linn were tested in the bioassay, which involve determination of time of paralysis of the worms. Albendazole was included as reference standard. The most activity was observed with aqueous extract as compared to standard drug. The results from the above studies indicate that plant Sida cordifolia Linn. possesses potent antioxidant and anthelmintic activity.
Tillage and Rice-Wheat Cropping Sequence Influences on Some Soil Physical Properties and Wheat Yield under Water Deficit Conditions  [PDF]

Abstract: Adopting a better tillage system not only improves the soil health and crop productivity but also improves the environment. A field experiment was conducted to investigate the effects of tillage and irrigation management on wheat (Triticum aestivum L.) production in a post-rice (Oryza sativa L.) management system on silty clay loam soil (acidic Alfisol) for 2003-2006. Four irrigation levels (RF: rainfed; I1: irrigation at crown root initiation (CRI); I2: irrigation at CRI + flowering; I3: irrigation at CRI + tillering + flowering), and two tillage systems (ZT: zero tillage and CT: conventional tillage) were tested. Zero tillage compared to CT, resulted in higher bulk density (1.34 vs 1.23 Mg –3), lower total porosity (48.7 vs 52.9%), higher penetration resistance (1.51 vs 1.37 MPa), lower saturated hydraulic conductivity (1.60 vs 92.0 mm h–1), lower infiltration rate (9.40 vs 36.6 mm h–1) and higher volumetric available water capacity (7.9 vs 7.5%) in the surface 0.15 m soil layer. Irrigation levels significantly affected crop water use, wheat yield, and water use efficiency (WUE). Average total water use was 461, 491, 534 and 580 mm under RF, I1, I2 and I3 treatments, respectively. Grain and straw yield of wheat were statistically the same under ZT and CT during 2003-2004; the values, averaged over four irrigation levels were 2.10 and 2.38 Mg a–1 for grain, and 3.46 and 3.67 Mg a–1 for straw, respectively. Grain yield declined by 22%, 11% and 8% of I3 (2.32 Mg ha–1) with RF, I1 and I2 treatments, respectively, under ZT; and by 13%, 8% and 5% of I3 (2.61 Mg ha–1) with RF, I1 and I2 treatments under CT. Average values of WUE were 4.33 kg ha–1 m–1 and 2.35 m3–1 grain for the ZT and CT treatments. Wheat yield increased with increased irrigation levels for all the cropping seasons. Results from this study concluded that ZT system was better compared to the CT system even with lower yields due to lower input costs for this treatment.
