the presence of tribolium castaneum (herbst) in a stored food results in contamination and substantial economic damage due to loss of the products and a decrease in nutritional value. this study was conducted to determine the pesticidal and pest repellent activities of roots of laportea crenulata gaud. against t. castaneum. pesticidal activity was determined using surface film method, whereas, ...

An important step in carcinoma progression is loss of cell-cell adhesion leading to increased invasion and metastasis. We show here that the protein tyrosine phosphatase, PTP-PEST, is a critical regulator of cell-cell junction integrity and epithelial cell motility. Using colon carcinoma cells, we show that the expression level of PTP-PEST regulates cell motility. Either transient small interfe...

lepidoteran pests of sugar beet (beta vulgaris l.) cause a severe yield reduction in the most sugar beet growing areas of the world as well as in iran. due to limited genetic resources of resistance to insect pest and polygenic inhertance, improvement of pest resistance in beet by conventional breeding is a difficult task. biotechnological enhancement by introducing insect resistance genes such...

Dermatology clinics represent a key opportunity to screen patients with psoriasis for psoriatic arthritis (PA) which often remains unrecognised. A significant proportion of adults with psoriasis develop arthropathy [5] with around two-thirds having progressive arthritis.[6] NICE has recognised this by the annual use of a validated screening tool such as psoriasis epidemiological screening tool ...

First published April 24, 2003; 10.1152/ajpheart.01127. 2002.—Vascular injury increases nitric oxide (NO) levels, and this effect may play a counterregulatory role in...

tera, Siphonaptera or Pulicidre. It is closely related to the common flea, from which, however, it differs in habits. Its nearest relation in Asia is Sarcopsylla gallinacea, Westwood, -which was described by Professor Westwood (Entomologists' Monthly Magazine, Volume XI, 187^-75, p. 2-46) from specimens found fastened to the eyelids and on the neck of domestic fowls at Colombo. The same species...
