Screening of Coriander Genotypes for their Relative Susceptibility against Aphids under Field Conditions
The field experiments were conducted during Rabi 2013-14 and 2014-15 to screen out twelve varieties/entries of coriander (Coriandrum sativum L.) for their relative susceptibility against aphids. None of the varieties/entries escaped the infestation of aphids. The build-up of aphid infestation started from second half of December and reached to its maximum in the first to third week of February in both years and then gradually declined. On the basis of grade index of mean aphid population, coriander varieties RCr- 684 (25.45 aphids/plant), RCr-446 (26.45 aphids/plant), ACr-1 (26.60 aphids/plant), RCr- 436 (41.75 aphids/plant), Gujarat Coriander-2 (42.45 aphids/plant), Pant Haritma (43.50 aphids/plant) and Gujarat Coriander-1 (43.70 aphids/plant) were categorized as least susceptible, Rajendra Swati and RCr-41 were moderately susceptible, whereas, Swati (CS-6), Sadhna (CS-4) and Sindhu (CS-2), 73.88, 70.60 and 69.50 aphids/plant, respectively were categorized as highly susceptible varieties of coriander against aphids under field conditions. Coriander variety RCr-684 received maximum yield (16.82 and 16.63 q/ha) for both the years followed by ACr-1 and RCr-446
Evaluation of different plant powders as seed protectants against rice moth, Corcyra cephalonica Stainton
The present study was aimed to develop the eco-friendly and economic approaches to keep the stored food grains free from insect attack would be using the plant products as grain protectants. In the context of biological control as an alternative to chemical control, under laboratory conditions, different plant powders viz., dharakkernel and leaf (Melia azadirach L.), neem kernel and leaf (Azadirachta indica Adr. Juss), karanj kernel (Pongamia glabra), aak leaf (Calotropis procera Br.), datura leaf (Datura alba Nees.), citrus leaf (Citrus lemon L.), podina leaf (Mentha arvensis) and tulsi leaf (Ocimum sanctum L.) were compared, at three rate of application (1.0, 2.5 and 5.0 g per 100 g seeds), as protectants against infestation of sorghum (Sorghum bicolor (L.) Moench) seeds by the storage pest Corcyra cephalonica Stainton. The larval period of test insect got progressively increased with the increase in dose level of different plant powders. The maximum (77.83%) and minimum (37.83%) reduction in adult emergence was observed in dharak kernel powder and tulsi leaf powder, respectively. The test insect developed on seeds treated with dharak kernel powder laid significantly (PΓΖ 0.5) minimum number of eggs (80.33 eggs/ female) followed by neem kernel powder (85.66 eggs/female). The dharak and neem kernel powders were found most effective in reducing the longevity of male (3.96 and 5.13 days) and female adults (4.63 and 4.97 days), respectively. The results suggest that these materials tested have the potential in the development of post-harvest protection technology against, C. cephalonica, the major pest of stored grains

Removal of hexavalent chromium Cr (VI) using activated carbon prepared from mango kernel activated with H3PO4
The present work reported the adsorption of Cr (VI) from aqueous solutions on activated carbon prepared from mango kernel, a seasonal waste from mango fruits. Kernels from dried mango fruit shells were taken out and pulverized in a micro-pulverizing mill. The powder thus obtained was activated with 40% H3PO4 and carbonized at 600 Β°C for 1 hour in an inert atmosphere. Physico-chemical characteristics such as elemental composition, surface area, functional groups and surface morphology of the activated carbon were analyzed using elemental analyzer, BET surface area analyzer, FTIR spectroscopy and SEM analysis respectively. Batch adsorption experiments were performed to investigate the effects of Cr (VI) concentration, carbon dose, pH, rate of agitation, time and temperature. The maximum adsorption capacity of Cr(VI) was found to be 7.8 mg gβ1 at pH 2 and temperature 35 Β°C. The Langmuir adsorption isotherm best represented the equilibrium data and a pseudo-second order relation represented the adsorption kinetics

Analgesic use and potential hearing loss: a pharmacovigilance study
Background: Hearing loss is the most common sensory deficit in humans today. In India, as per WHO there are approximately 63 million people, who are suffering from significant auditory impairment and estimated prevalence at 6.3% in Indian population. The objective of the study was to determine the potential hearing loss in patients on analgesics.Methods: Prospective, observational study examined the association between analgesic use and potential hearing loss in 30 patients receiving NSAIDS. Data was collected using specialized designed case record form. The clinical signs like onset of tinnitus, appearance of another sound that didn't exist before, sinus infection or a respiratory illness, development of vertigo or spinning sensation were looked for. Audiometry test was advised for all the patients receiving analgesics.Results: Total of 30 patients were included in the study. Male predominance was noted Maximum patients were in the age group between 35-45 years (33.33%). The socioeconomic status was analyzed using revised kuppuswamy scale. 30% (n=09) of patients were in lower class. Majority of the patients were reported with road traffic accidents (n=19; 63.33%) and received analgesics for more than 2 weeks. Patients received different combination of NSAIDs among which aceclofenac was most commonly prescribed. 11 (36.66%) patients had hearing loss received either diclofenac or aceclofenac for more than 25 days.Conclusions: Regular usage of NSAIDS may increase the risk of hearing loss and the impact could be larger on younger individuals. Hence, extra precaution to be taken while prescribing NSAIDS
Safety profile of imatinib in Indian chronic myeloid leukemia patients
Introduction: Imatinib mesylate has become the choice of drug in the treatment of chronic myeloid leukemia. Objective:
To study safety profile of Imatinib (specific inhibitor or bcrabl tryosne kinase protein) in Philadelphia chromosome t {(9:22),
bcr-abl} positive chronic myeloid leukemia (CML) chronic phase patients. Materials and Methods: After IEC clearance, 36,
BCR-ABL positive CML patients in the chronic phase of the disease were recruited. Imatinib mesylate (Gleevec, Novartis), was
started (400mg daily) and followed up weekly in first month, two weekly till three months & monthly thereafter. Safety profile
data, recorded in pre-designed proforma, were analyzed for time of onset, duration and severity of adverse effects. Causality
relationship of recorded adverse events was established with imatinib therapy using WHO-UMC criteria. Results: A total of 222
adverse events were reported in 36 CML-CP patients over 12 months of follow up. Thrombocytopenia was the most commonly
reported in 60% of the patients followed by musculoskeletal (17%), dermatological (16%), gastrointestinal disturbances (13%),
body weight changes (11%), superficial edema (8%) and liver enzyme rise (4%). More than 80% events reported within months of
therapy which persisted for less than 3 months in most of the cases. No treatment was needed in 68% of cases while therapy
alteration was not needed in 88% of cases. Most of the reactions (60%) had probable relationship with the therapy. Conclusion:
Imatinib was well tolerated, having only mild to moderate grade of toxicities, mostly within 3 months of therapy and most of them
persisted for less than 3 months of duration, requiring only symptomatic treatment and drug withhold or dose decrement in only
few cases
Stability analysis of yield, yield attributes and essential oil content in fennel (Foeniculum vulgare Mill.) evaluated under a long-term organic production system
Eight varieties of fennel (Foeniculum vulgare Mill.) were evaluated under field trial for their stability of yield, yield attributes and essential oil content under the organic production system in six consecutive years from 2016 to 2021. Mean square due to environment + (variety Γ environment) was significant for all the traits studied indicating the existence of variety Γ environment interaction. Based on the mean performance, regression coefficient and deviation from regression values, it was found that stability of yield and yield components are imparted in the varieties, GF-12 and AF-1 across the years through the stable performance of characters and like numbers of primary and secondary branches, number of umbels and umbellate and seed yield. However, variety RF-101 for essential oil content can be considered as most suitable, stable and adopted to organic production system compared to other varieties. Correlation analysis revealed highly positive relationship in plant height, number of primary branches, number of umbels and umbellate per plant and seed yield. Based on the findings, fennel growers are apprised to select stable high-yielding fennel varieties for the organic production systems in semi-arid regions of India. Along with their use in hybridization programmes to converge the stability characteristics of seed yield for the development of a stable variety adapted to a wider range of environments under organic production systems
