Gall-bladder duplication is a rare anatomical variation, which can affect safe performance of cholecystectomy and be a cause of persistent symptoms and a need for reoperation in case of accessory gall-bladder omission. A case of successfully performed elective laparoscopic cholecystectomy in a patient with duplicated gall-bladder accidentally intraoperatively disclosed is presented. The identif...

During the present study, the host–parasite relationship between mosquitoes and parasitic mites was investigated. The 8954 individuals of male and female mosquitoes belonging to 26 genera: seven each of Aedes and Culex, six of Anopheles and one each of Toxorhynchites, Coquillettidia and Uranotaenia were collected from 200 sites. The male and female mosquitoes were collected from the State of Ut...

BACKGROUND Demodex mites are involved in different skin diseases and are commonly detected by skin scrape tests or superficial biopsies. A new high-definition optical coherence tomography (HD-OCT) with high lateral and axial resolution in a horizontal (en-face) and vertical (slice) imaging mode might offer the possibility of noninvasive and fast in vivo examination of demodex mites. METHODS T...

Varroa mites (Varroa destructor Anderson and Trueman, 2000) are becoming resistant to acaricide treatments via metabolic and/or target site desensitivity. Results of a survey of mites from the Carl Hayden AZ lab and from cooperators in five locations (Arizona, California, Florida, Maine, North Dakota) showed that some mites were susceptible to all three acaricides (Amitraz, Coumaphos, Fluvalina...

Varroa destructor is a worldwide ectoparasite of serious economic importance for beekeeping. Severe colony mortality is routine in parasitized European honey bees (EHB) colonies in Europe, Asia and North America. This study was carried out in Heredia, Costa Rica. The reproductive ability of varroa mites was determined approximately 240 h after cell sealing in worker brood from four Africanized ...

The liver, gall bladder, and ventral pancreas are formed from the posterior region of the ventral foregut. After hepatic induction, Sox17+/Pdx1+ pancreatobiliary common progenitor cells differentiate into Sox17+/Pdx1- gall bladder progenitors and Sox17-/Pdx1+ ventral pancreatic progenitors, but the cell-extrinsic signals that regulate this differentiation process are unknown. This study shows t...

The effects of cigarette smoking and parity on the development of symptomatic gall bladder disease remain controversial. These relations have been examined in a cohort of 46000 women followed for up to 19 years during the Royal College of General Practitioners' (RCGP) oral contraception study. During follow up, 1087 women were recorded as experiencing their first ever episode ofsymptomatic chol...

Title of Dissertation: MECHANISMS UNDERLYING OUTBREAKS OF SPIDER MITES FOLLOWING APPLICATIONS OF IMIDACLOPRID. Adrianna Szczepaniec, Ph.D., 2009 Directed By: Professor Michael J. Raupp, Department of Entomology Imidacloprid is a widely used neonicotinoid insecticide with high efficacy and long residual activity, and it is frequently applied to manage insect pests in urban landscapes. Recent rep...

Life histories of "wild" house dust mites, Dermatophagoides pteronyssinus (Trouessart) (Acari: Pyroglyphidae), were compared with laboratory cultures by using a diet consisting of skin and dust or a laboratory diet consisting of dried liver and yeast. Under constant conditions of 25 degrees C and 75% RH, fecundity and rate of reproduction were higher in laboratory cultures on both diets compare...

Leprosis is a serious disease of citrus caused by Citrus leprosis virus C (CiLV-C, genus Cilevirus) whose transmission is mediated by false spider mites of the genus Brevipalpus. CiLV-C infection does not systemically spread in any of its known host plants, thus remaining restricted to local lesions around the feeding sites of viruliferous mites. To get insight into this unusual pathosystem, we...
