and , Potent Lethal/Repellent Agents against , Probable Carrier for Zoonosis.

Background: is a hard tick with importance in transmission of tick-borne diseases and zoonosis. Natural products are excellent alternative to pesticides. In this study for the first time, lethal and repellent activity of and against were studied.

In-vitro antigiardial activity and GC-MS analysis of Eucalyptus globulus and Zingiber officinalis essential oils against Giardia lamblia cysts in simulated condition to human’s body.

In order to finding of potent natural medication/agent which can kill giardial cysts in the interval between lysing of outer membrane of cysts due to exposure by acidic condition of stomach and their encystation in proximal small intestine, In-vitro antigiardial activity and GC-MS analysis of Eucalyptus globulus and Zingiber officinalis against Giardia lamblia were studied in simulated condition to human’s body singly and in combination. Essential oils were extracted and their chemical components were identified via GC-MS method. After purification, cysts were exposure to acidic condition and were challenged by different concentrations of essential oils in simulated condition to human’s body.

Mutations of Voltage-Gated Ionic Channels and Risk of Severe Cardiac Arrhythmias.

Background: Arrhythmias as important malfunctions of heart are known as abnormal rhythm of heart. Several causes can make arrhythmias and most of them are related to generation and/or conduction of action potential in heart. Action potential in myocytes results from the sequential opening and closing of ion channel proteins that span the plasma membrane of individual myocytes.

The insecticidal and repellent activity of ginger (Zingiber officinale) and eucalyptus (Eucalyptus globulus) essential oils against Culex theileri Theobald, 1903 (Diptera: Culicidae.

Insecticidal and repellent activity of essential oils of Zingiber officinale and Eucalyptus globulus against Culex theileri Theobald, 1903 as a wide-distributed species of mosquitoes in different parts of world with an important role in transmission of infectious organisms and agent were studied. Essential oils were extracted from fresh parts of plants and different concentrations of 250 μl/ml, 500 μl/ml, 750 μl/ml and 1 (undiluted extract) were prepared for each of essential oils. Insecticidal and repellent activity of essential oils against adult form of Culex theileri Theobald mosquitoes, collected from small pools located near the Zayande-Rood River in the Saman city, Iran, were examined via direct exposure method and Y-tube olfactometer bioassay, respectively.
