Efficacy of Major Plant Extracts/Molecules on Field Insect Pests
Insect pests are considered the major hurdle in enhancing the production and productivity of any farming system. The use of conventional synthetic pesticides has led to the emergence of pesticide-resistant insects, environmental pollution, and negative effects on natural enemies, which have caused an ecological imbalance of the predator-prey ratio and human health hazards; therefore, eco-friendly alternative strategies are required. The plant kingdom, a rich repertoire of secondary metabolites, can be tapped as an alternative for insect pest management strategies. A number of plants have been documented to have insecticidal properties against various orders of insects in vitro by acting as antifeedants, repellents, sterilant and oviposition deterrents, etc. However, only a few plant compounds are applicable at the field level or presently commercialised. Here, we have provided an overview of the broad-spectrum insecticidal activity of plant compounds from neem, Annona, Pongamia, and Jatropha. Additionally, the impact of medicinal plants, herbs, spices, and essential oils has been reviewed briefl
New, simple and cheap alternative to troponin test for diagnosis of acute myocardial infarction
628-630Acute
myocardial infarction (AMI) is often a fatal disorder in humans seen throughout
the world. It was earlier diagnosed with some serum enzymes like aspartate
transaminase, creatine phosphokinase and its isoenzyme CPK-MB and lactate dehydrogenase
which were shown to be increased in AMI. However, in the last few years importance
has been given to measuring serum troponins released from the injured
myocardium toconfirm an AMI. Troponin estimation involves immunological
technique, which is expensive with other associated problems like shelf life of
reagents, number of samples to be analysed ,and availability of the kit itself,
used for estimation. Under these circumstances the present work involves the measurements
of total salt soluble proteins which are proteins associated with troponins
also released from myocardium of a
patient with AMI. This new test
overrules all the disadvantages of the troponin test but seems equally viable and
useful for diagnosis of AMI.</span
<i>In vitro </i>studies on peroxidative changes leading to hemolysis of erythrocytes infested with malarial parasite <i>Plasmodium vivax</i>
729-730Blood
erythrocytes of 25 confirmed malarial patients infested with P. vivax were
analyzed for peroxidation and hemolysis and results compared with 10 uninfected
normal control samples. Results indicated significant increase in peroxide formation measured
as malondialdehyde, both in presence and absence of H2O2,
in parasite infested erythrocytes. These changes induced hemolysis of infected
erythrocytes which was increased manifold in presence of H2O2 and
could probably be the reason for extensive anemia reported in malaria
