Impact of Seed-born Colletotrichum lindemuthianum on French Bean Seed Quality

French bean seed samples were collected from different parts of Tamil Nadu including both tropical and temperate region including four cultivars viz.,Arkakomal,Premier,Rajmash DPU 88-4 and Watex.The variety Watex was found to maximum per cent seed infection of C.lindemuthianum with more discolorations.Among the various techniques adopted for detection,agar plate method was found to be best and yielded maximum per cent seed infection.Direct correlation was obtained between seed discoloration and per cent seed infection.The pathogen was found to be present mostly in seed coat and cotyledon and rarely in embryonic axis.The artificial inoculation of 45-day-old plants resulted in maximum disease incidence,resultant seed infection and minimum seed yield /plant and 100 grain weight

Dynamic Interface to Enhance Network Efficiency Using Channel Allocation

Abstract--Wireless Sensor Networks (WSN) is a group of spatially dispersed and dedicated sensors for monitoring and recording the physical conditions of the environment and organizing the collected data at a central location. The sensor nodes are extraordinarily limited in resources, so the important aim of designing routing protocol of WSN is to improve the routing efficiency and maximize the lifetime of networks. In the recent past, the routing efficiency and its issues can be solved by various protocols. In this paper we enhanced many to one transmission with AODV protocol and efficient channel allocation. We have implemented flat multi-hop routing algorithms which enable routing of data in a fashion that minimizes the power consumption of the WSN they fail to exploit the data aggregation opportunities by virtue of data collected from the WSN. In many WSN applications with the relatively high node density, the data collected by individual nodes are highly redundant, thus making data aggregation a very attractive scheme in WSNs. Hybrid multi-hop routing algorithms aim to capitalize on the highly correlated nature of WSN's collected data. It can improve the routing efficiency and channel allocation in cluster networks. The cluster head selection is obtained based on energy level and routing efficiency of the network

The effect of magnesium sulfate as an adjuvant to 0.5% bupivacaine on motor and sensory supraclavicular brachial plexus blockade

Background: Magnesium is a physiologic cation that blocks neuromuscular transmission and does not allow the nerve to be stimulated. This study investigates the effect of adding magnesium sulfate to 0.5% bupivacaine to extend the duration of sensory and motor blocks of the supraclavicular brachial plexus in orthopedic surgeries of the upper extremities.Methods: This controlled randomized double-blind study was performed on patients who were candidates for orthopedic surgery of the upper extremities. A total of 60 patients between 18 and 60 years with ASA Class 1 or 2 participated in the study. One Group M received 0.5% bupivacaine (1.5 mg/kg) with magnesium sulfate 20% (3 ml) as the case group, while the second Group P received 0.5% bupivacaine (1.5 mg/kg) with normal saline (3 ml) as a placebo to block the supraclavicular brachial plexus using nerve locator. The duration of the sensory and motor block of the supraclavicular brachial plexus was monitored and evaluated using the pinprick and modified Bromage scale.Results: A total of 60 patients were included in the study with 30 patients having received 0.5% bupivacaine plus magnesium and the other 30 patients having received 0.5% bupivacaine plus normal saline. The mean sensory block duration in the case Group M was 249±9.36 and in control Group P was 160±5.62 (p<0.39). The mean motor block duration in the case Group M was 232±9.64 and in control Group P was 147±26.52 (both p<0.32). The mean onset of sensory block in case Group M was 15.5±2.16 and the onset block in control Group P was 12.73±1.18 (p<0.49; statistically not significant). The mean onset of motor block in case Group M was 23.5±1.1 and the onset block in control Group P was 41±3 (p<0.53; statistically not significant).Conclusions: The addition of magnesium sulfate to 0.5% bupivacaine increased the duration of motor and sensory supraclavicular brachial block in the upper extremities during surgeries when compared to the use of 0.5% bupivacaine alone, though statistically not significant, but definitely in clinically significant proportions

A PROSPECTIVE STUDY FOR THE EVALUATION OF NERVE CONDUCTION ABNORMALITIES IN NEWLY DIAGNOSED TYPE 2 DIABETIC PATIENTS

Objectives: Peripheral neuropathy is the one of the frequently encountered complication of type 2 diabetes mellitus (T2DM). Although, the prevalence of diabetic peripheral neuropathy is associated with the diabetes duration, in some cases, the state of neuropathy is evident at the time of diagnosis. In this backdrop, the present study was carried out to evaluate the nerve conduction abnormalities in newly diagnosed T2DM. Methods: This was a prospective study carried out on 30 newly diagnosed T2DM within a time range of 1 month. The patient symptoms such as weakness, burning and tingling senzation, hyperesthesia, and foot ulcer and gait abnormalities were recorded. Nerve conduction analysis of upper limb and lower limb of non-dominant hand side was done using neuro pack S1 machine. Results: Thirty newly diagnosed T2DM patients were enrolled in the present study. The mean age of the patients was found to be 58.12±15.28 years. Distal motor latencies were elevated in T2DM patients as compared to the controls (p&lt;0.05). Further, there was significant prolongation of F-wave latencies in the upper and Lower limbs of the patients as compared to the controls (p&lt;0.05). In addition, there was a significant decrease in sensory conduction velocities in T2DM patients as that of the controls (p&lt;0.05). Conclusion: The study concludes that newly diagnosed T2DM is susceptible to DPN with high incidence rates. Hence, it is essential to perform the nerve conduction studies in newly diagnosed T2DM patients for the early detection and better management and also to prevent the complications

Wash durability and optimal drying regimen of four brands of long-lasting insecticide-treated nets after repeated washing under tropical conditions

<p>Abstract</p> <p>Background</p> <p>The current study was undertaken to determine the optimal wash-drying regimen and the effects of different washing procedures on the efficacy, and durability of four brands of newly introduced long-lasting insecticide-treated nets (LLINs) under tropical conditions.</p> <p>Methods</p> <p>In the current study, the following four LLINs were tested: Olyset^®, PermaNet ^®2.0, BASF^®and TNT^®. Nets were divided into three sets; one set was washed by hand rubbing and air-dried either hanging or spread on the ground in direct sunlight or hanging or spread on the ground under the shade. A second set was washed using the WHO protocol (machine) and the third set was washed by beating the nets on rocks. The biological activities of the nets were assessed by a three-minute bioassay cone test and the residual insecticide contents were determined using high performance liquid chromatography (HPLC) procedure.</p> <p>Results</p> <p>Nets that were dried hanging under the shade retained more insecticide, 62.5% and recorded higher mortality compared to nets which were dried lying on the ground in direct sunlight 58.8%, nets dried under the shade spread on the ground 56.3%, and 57.8% for nets dried hanging in direct sunlight. It was also observed that nets washed by the standard WHO protocol, retained more insecticide and were more effective in killing mosquitoes compared to nets washed by local methods of hand rubbing and beating on rocks. There were significant differences between drying regimens (p < 0.0001) and between washing procedures (p < 0.001) respectively. However, the effect of net type was statistically insignificant. The statistical differences on individual nets were also compared, for PermaNet^®and TNT there were no significant differences observed between the four drying regimens (<it>p </it>= 0.7944 and 0.4703) respectively). For BASF and Olyset, the differences were significant (p < 0.001 and p > 0.0001).</p> <p>Conclusion</p> <p>The results of this study suggest that washing and drying regimen influence the insecticidal activity of LLINs. The standard WHOPES washing protocol underestimates the amount of insecticide washed from LLINs compared to the abrasive washing procedures that are used in the field. This suggests that there is need to educate net users to adopt a more gentle washing procedure while handling LLINs. The education should accompany net distribution campaigns.</p
