Metabolic Resistance in Bed Bugs

open access: yesInsects, 2011
Blood-feeding insects have evolved resistance to various insecticides (organochlorines, pyrethroids, carbamates, etc.) through gene mutations and increased metabolism. Bed bugs (Cimex lectularius) are hematophagous ectoparasites that are poised to become

Effect of pesticide mixture on value of fresh, fermented and pickles cucumbers

open access: yesActa Agrobotanica, 2013
In years 1998-1999 effects of fungicides (azoxystrobin and copper hydroxide), insecticides (etafenproks and pirimicarb) and their mixtures on chemical composition and organoleptic quality of fresh, fermented and pickled cucumbers were studied_ To ...

Evaluating the Usefulness of Paratransgenesis for Malaria Control [PDF]

open access: yes, 2013
Malaria is a serious global health problem which is especially devastating to the developing world. Mosquitoes are the carriers of the parasite responsible for the disease, and hence malaria control programs focus on controlling mosquito populations. This is done primarily through the spraying of insecticides, or through the use of insecticide treated ...

Dual‐Responsive Phosphorus‐Based Fluorescent Sensors: Synthesis and Selective Metal Sensing of Pyrazolyl Phosphine Oxides

open access: yesAngewandte Chemie, EarlyView.
Pyrazolyl phosphine oxides are shown to act as dual‐responsive fluorescent sensors, displaying a selective “turn‐off” fluorescence response for Fe3+ and a “turn‐on” response for Al3+. These systems serve as a new framework in the field of sensing materials based on main‐group elements such as phosphorus. Abstract Despite a wealth of previously reported

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Dengue disease, basic reproduction number and control [PDF]

open access: yesInt. J. Comput. Math. 89 (2012), no. 3, 334--346, 2011
Dengue is one of the major international public health concerns. Although progress is underway, developing a vaccine against the disease is challenging. Thus, the main approach to fight the disease is vector control. A model for the transmission of Dengue disease is presented.
