Plastic No More … Also in Kenya

Plastic bags are also a major contributor to the 8 million tonnes of plastic dumped in the sea every year. Credit: UNEPBy Baher KamalROME, Apr 4 2017 (IPS)Good news: Kenya has just joined the commitment of other 10 countries to address major plastic pollution by decreeing a ban on the use, manufacture and import of all plastic bags, to take effect in six months. The Kenyan decision comes three weeks after the UN declared “war on plastic” through its new UN Clean Seas initiative, launched on at the Economist World Ocean Summit in Bali (February 22-24, 2017).The initiative’s campaign urges governments to pass plastic reduction policies; industry to minimise plastic packaging and redesign products; and consumers to change their throwaway habits before irreversible damage is done to our seas.“Kenya is taking decisive action to remove an ugly stain on its outstanding natural beauty,” Erik Solheim, Head of UN Environment Programme (UNEP) commented on the Nairobi government’s decision.“Plastic waste also causes immeasurable damage to fragile ecosystems – both on land and at sea – and this decision is a major breakthrough in our global effort to turn the tide on plastic.”Some 100 million plastic bags are handed out every year in Kenya by supermarkets alone, the UN informed, adding that long identified as a major cause of environmental damage and health problems, they kill birds, fish and other animals that mistake them for f...

Abstract An imbalance in oxidants and antioxidants is observed during malaria and dengue infections which is associated with the production of reactive oxygen species (ROS) via haem degradation or immune activation, a contributing factor for disease pathogenesis. The levels of non-enzymatic antioxidants and total antioxidant status (TAS) in malaria and dengue patients were analysed and compared with healthy controls. Particular attention was paid to elevated levels of total bilirubin (TB) and uric acid (UA) during disease progression and haemolysis and noticed a significant increase in dengue patients (dengue>P...

Authors: Sogan N, Kapoor N, Singh H, Kala S, Nayak A, Nagpal BN Abstract Background &objectives: Vector control strategies play significant role in reducing the transmission of malaria, dengue and other vector-borne diseases. The control of vector population using synthetic insecticides has resulted in development of insecticide resistance and negative effects on humans and environment. The present investigation evaluated the larvicidal potential of methanol, dichloromethane and hexane extracts of leaves and seeds of Ricinus communis (castor) plant against the early IV instar larvae of the dengue vector, Aedes ...

NatarajanAbstractMosquitoes transmitted several vector borne diseases like malaria, dengue, lymphatic filariasis and now Zika virus. Synthetic chemicals cause much illness to humans, non-target organisms and natural ecosystem. In the present study, larvicidal efficacy of Naringi crenulata (Rutaceae) different leaf extracts and bioassay guided fractions against Culex quinquefasciatus, phytochemical screening and secondary metabolites were characterized by TLC, HPLC,...

In this study, we developed and validated a reverse transcription-polymerase chain reaction (RT-PCR) for the detection of DENV adapted for use in field settings. Reverse transcription-polymerase chain reaction was performed directly from plasma samples without RNA extraction. The assay detected all four serotypes of DENV spiked into blood or plasma. Our RT-PCR does not cross-react with pathogens that cause symptoms that overlap with dengue infection. The test performed equally well in a conventional laboratory qPCR instrument and a small, low-cost portable instrument that can be used in a field setting. The lower limit of ...

Conclusions Apart West Nile virus (78), thousands of congenital microcephaly cases, fetal brain tissue damage and neurological syndromes have been associated with ZIKV infection. Unfortunately, the epidemics of this mosquito born, and a relative stable virus is on a rise. Although congenital microcephaly is a rare disorder however, due to lack of standardized diagnostic test facilities, the incidence in the geographically widespread ZIKV epidemic regions is higher. Animals studies showed that ZIKV is a neurotropic virus. It directly targets the developing embryonic brain cells by inducing apoptosis, cell-cycle arrest, and...

Conclusion: Together, our results point that Ae. aegypti larvae show high plasticity to feed, being able to develop under different microorganism-based diets. The important role of Ae. aegypti in the spread of infectious diseases requires further biological studies in order to understand the vector physiology and thus to manage the larval natural breeding sites aiming a better mosquito control. Introduction Mosquitoes are medically the most significant group of insects due to their important role in the widespread of several human infectious diseases including malaria, dengue fever, encephalitis, yellow fever and f...

Abstract With almost half of the world population living at risk, tropical infectious diseases cause millions of deaths every year in developing countries. Considering the lack of economic prospects for investment in this field, approaches aiming the rational design of compounds, such as structure-based drug discovery (SBDD), fragment screening, target-based drug discovery, and drug repurposing are of special interest. Herein, we focused in the advances on the field of SBDD targeting arboviruses such as dengue, yellow fever, zika and chikungunya enzymes of the RNA replication complex (RC) and enzymes involved in a...
