BACKGROUND Reduction of intraoperative bleeding is necessary to achieve the ideal surgical field for the endoscopic sinus surgery (ESS). Intraoperative intra nasal bleeding is influenced by various anesthetics. This study compared surgical field condition between propofol/remifentanil (PR) based anesthesia and desflurane/remifentanil (DR) based anesthesia. METHODS American Society of Anesthes...

Chronic rhinosinusitis (CRS) is a common disease which is usually diagnosed clinically, considering the combination of natural history, physical examination and imaging studies. This study aimed to evaluate the clinical value of routine postoperative histopathologic examination (POHE) in patients with a clinical diagnosis of chronic rhinosinusitis with polyposis (CRSWP), or without polyposis (C...

In the late-nineteenth and early-twentieth centuries, California agriculture underwent a fundamental transformation as the state’s farmers shifted from the production of wheat to a rich variety of tree, vine, and row crops. This transformation required a wholesale shift in the production processes, with new farming practices, new labor systems, and new marketing structures. But success also req...

The biology, host plants, and pest status of Podontia Dalman, 1824 species are reviewed. Natural history of Podontia congregata Baly, 1865 a flea beetle endemic to southern India, is reported for the first time. It is distributed from the Western Ghats Mountains westward to the plains. Clusiaceae is reported as a new host plant family for Blepharida-group species, with Garcinia gummi-gutta (L.)...

Laboratory assays show that parasites often have lower heat tolerance than their hosts. But how physiological tolerances and behavioral responses of hosts combine to affect ecological interactions in heterogeneous field environments is largely unknown. We addressed this challenge using the model insect system braconid wasp parasitoid, Cotesia congregata, its caterpillar host, Manduca sexta. use...

Toxicity of 17 commonly used insecticides used to control diamondback moth, Plutella xylostella (L.) was evaluated against adults of Cotesia plutellae Kurdjumov. The insecticide concentrations studied were equivalent to those recommended in the field. Adults of the parasitoid were released into exposure kits with fresh dry insecticide film for 24 hours, at which time mortalities were noted. The...

Polydnaviruses are endogenous particles that are crucial for the survival of endoparasitoid wasps, providing active suppression of the immune function of the lepidopteran host in which wasp larvae develop. The Cotesia rubecula bracovirus (CrBV) is unique in that only four gene products are detected in larval host (Pieris rapae) tissues and expression of CrBV genes is transient, occurring betwee...
