The benzoylurea chitin synthesis inhibitor dißubenzuron was evaluated as a rodent feed-through for the control of immature stages of Phlebotomus papatasi Scopoli (Diptera: Psychodidae). The development and survival of second instars of P. papatasi larvae that were fed feces from Syrian hamsters, Mesocricetus auratus, that had been fed a diet containing 0, 8.97, 89.7, or 897 ppm dißubenzuron was...
Experiments were conducted to evaluate novaluron as a feed-through larvicide to control immature phlebotomine sand flies (Phlebotomus papatasi Scopoli) (Diptera: Psychodidae). The minimum effective concentration of novaluron against sand fly larvae fed hamster feces treated with novaluron, or feces of hamsters fed a diet containing novaluron, was 9.88 and 9.88 x 10(-1) mg/kg, respectively. Fece...
BACKGROUND Zoonotic cutaneous leishmaniasis (ZCL) is an increasing health problems in many rural areas of Iran. The aim of this study was to introduce a new alternative rodenticide to control the reservoirs of ZCL, its effect on the vector density and the incidence of the disease in hyperendemic focus of Esfahan County, central Iran. METHODS The study was carried out from January 2011 to Janu...
Glycoprotein 130 Receptor Signaling Mediates a-Cell Dysfunction in a Rodent Model of Type 2 Diabetes
Dysregulated glucagon secretion accompanies islet inflammation in type 2 diabetes. We recently discovered that interleukin (IL)-6 stimulates glucagon secretion from human and rodent islets. IL-6 family cytokines require the glycoprotein 130 (gp130) receptor to signal. In this study, we elucidated the effects of α-cell gp130 receptor signaling on glycemic control in type 2 diabetes. IL-6 family ...
Overview The goal of this chapter is to describe recent efforts at understanding the functional significance of " prefrontal " areas in the cerebral cortex of rodents with regard to cognitive and motivational control. Previous discussions on the comparative anatomy of the prefrontal cortex have been framed around the question " Do rats have prefrontal cortex? " 46, 61. Researchers using rodents...
BACKGROUND Rodent infestations are a public health problem in poor urban communities. The use of illegal street pesticides to control rodent infestations with resulting poisonings is an additional public health concern receiving limited attention in many developing countries, including South Africa. METHODS Participants in a household intervention in two poor urban areas of Cape Town, South A...
Groups of Swiss ICR mice were fed 1000 ppm polybrominated biphenyls (FireMaster BP-6) in rodent chow for 4, 8, 11, and 14 days. Control groups were fed standard rodent chow without FireMaster BP-6. Animals were killed at the end of each feeding period and the livers examined by electron microscopy. EM changes noted were progressive increase in size of hepatocytes, a decrease in rough endoplasmi...
4-Ipomeanol is a pulmonary toxin in cattle and rodents that is metabolically activated by cytochromes P-450 (P-450s). P-450-mediated activation of 4-ipomeanol to DNA binding metabolites was evaluated using a vaccinia virus complementary DNA expression system and an in situ DNA-binding assay. Twelve human P-450s and two rodent P-450s were expressed in human hepatoma Hep G2 cells and examined for...
