A study of clinical and laboratory profile of dengue positive cases in hadoti region Rajasthan, India

 Background: Dengue fever is one of the most common arboviral mediated outbreaks reported with increased prevalence year after year with considerable morbidity and mortality in hadoti region. the aim to study various clinical and laboratory manifestations of Dengue fever admitted in MBS Hospital KOTA, with a diagnosis of Dengue fever according to WHO protocol from December 2018 to January 2020.Methods: Prospective observational study was undertaken among adult patients. 132 patients were studied and analysed. And diagnosis was confirmed with Dengue IgM ELISA test. Other routine investigations done were routine hematological and biochemical investigations.Results: A total of 132 cases, out of which 95 cases of Dengue Fever (DF), 34 cases of dengue hemorrhagic fever and 3 cases of Dengue Shock syndrome, out of which Male: Female ratio was 2.1. and mean age of presentation was 37. Fever and myalgia were the most common finding (100%) followed by arthralgia and headache. Pruritus was found in 21 cases (15.9%) which carried a significant difference between DF and DHF (p value 40 IU/L) was seen in 39 cases (29.54%.). Pleural effusion was seen in 4 cases (3%), of which 3 cases of DHF and 1 case of DSS. Ascites in 6 cases (4.8%), all cases belong to DHF. Gall bladder wall thickening was seen in 28 cases (21.21%) of which 20 cases (54.04%) were of DHF. Melena was the most common bleeding manifestation. Skin rash was found to be positive in 40.5% cases. Hess test was positive in 4 cases (10.8% of DHF).Conclusions: Incidence of dengue fever is on the rise in hadoti region and one of the most important differential diagnosis of patients presenting with fever during monsoon and post monsoon seasons

Evaluation of Productivity of Pearl Millet and Clusterbean and Growth Parameters of Neem Strains under Agro-Forestry System under Semi-Arid and Rainfed Condition

Neem (Azadirachta indica) tree is a native to Indian sub-continent and found throughout the India with maximum number of trees which are distributed over 70-75% geographical area of this country. It is distributed throughout south and southeast Asia, Australia, Africa and many other countries in central and south America including Carribean, Puer to Rica and Virgin Islands (Ram Mohan and Nair, 1993). The tree has been considered so invaluable and miraculous that it became a major inseparable component of the Indian ecosystem. Neem has been held in high esteem because of it provde medicinal and insecticidal properties. As a single tree it has maximum uses like medicines, bio-pesticides, mosquito repellents, fertilizers, diabetic foods, soaps, lubricants, gums, agriculture implements, tooth paste, tooth sticks, contraceptives etc. which is receiving worldwide recognition for its variety of bio-active principles. For a farmer the tree provided seeds, leaf and bark which could be converted into fertilizer and pest control material and medicine for livestock. Neem enjoys a wide range of climatic and edaphic factors. It is successfully grown in arid, semi-arid, wet tropical and sub-tropical climates. It is tolerant to high temperature up to 49oC but susceptible to excessive frost and water logged conditions (Hegde, 1993). Its performance is well on poor, shallow, stony or sandy soils and can be established easily without irrigation in hot and dry regions with low annual rainfall of 500 mm or less. It can be planted at farm/field boundaries, road sides, canal banks, river banks and wherever any space is vacant. Neem is the most ideal tree known to be successful under various agroforestry systems. Many Indian companies are currently engaged in processing neem seeds for extracting Azadirachtin. A large number of liquid and powdered formulations are being marketed in India. Although, this tree has tremendous potential, but till now it is to be exploited for full genetic potential in terms of growth and Azadirachtin content. By increasing Azadirachtin content more than 0.50 % in seed kernel much better price would be fetched (Gupta et. al. 2010). Realizing the economic potential of neem products in world market and good adaptability in wider climatic conditions and land situations in India, Central Agroforestry Research Institute, Jhansi collected a good amount of neem germplasm from nine states and evaluated critically for all the important characters and published in the form of “Neem catalogue” (Gupta et. al. 2011)

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

Structural, Magnetic and Magneto-caloric studies of Ni50Mn30Sn20Shape Memory Alloy

We have synthesized a nominal composition of Ni50Mn30Sn20 alloy using arc melting technique. Rietveld refinement confirms the austenite L21 structure in Fm-3m space group. Electrical resistivity has been found to clearly exhibiting two different phenomena viz. a magnetic transition from paramagnetic to ferromagnetic and a structural transition from austenite to martensitic phase. Thermo-magnetization measurements M(T) confirms ferromagnetic transition temperature TC at 222 K and martensitic transition starting at 127 K(MS). Magnetization measurement M(H) at 10 K confirms the ferromagnetic state. Frequency dependence of ac susceptibility \c{hi}' at low temperature suggests spin glass behavior in the system. The isothermal magnetic entropy change values have been found to be 1.14 J/Kg.K, 2.69 J/Kg.K and 3.9 J/Kg.K, with refrigeration capacities of 19.6 J/kg, 37.8 J/kg and 54.6 J/kg for the field change of 1, 2 and 3 Tesla respectively at 227 K.Comment: 16 pages text + Figs.
