A new generation of nerve cuffs suitable for stimulation, recording and modulation of nerve activity has been tested in our laboratory and elsewhere. The walls are molded of low-durometer silicone and incorporate flexible electrodes, Teflon-coated stainless steel leads and an interlocking opening/closing system. Stimulation and recording cuffs can be either single-channel or multichannel. Singl...

BACKGROUND Improvements in the design of the endotracheal tube (ETT) have been achieved in recent years. We evaluated tracheal injury associated with ETTs with novel high-volume low-pressure (HVLP) cuffs and subglottic secretions aspiration (SSA) and the effects on mucociliary clearance (MCC). METHODS Twenty-nine pigs were intubated with ETTs comprising cylindrical or tapered cuffs and made o...

UV reflectance of plumage display is important in mate choice of many avian species, but its role in off-body display has received little consideration. Male satin bowerbirds (Ptilonorhynchus violaceus) collect objects for use as bower decorations. Here, I test the hypothesis that UV and non-UV colors are important in choice of satin bowerbird bower decorations (colored squares and blue parrot ...

abstract this article tries to look at the jewels of the ancient luristan (nowadays luristan province and some parts of ilam and kermanshah provinces), and to have a survey on this precious art and its typology. these jewels have been gathered by way of many scientific and unscientific excavations at last decades in the ancient sites like: kalmakareh, varkaboud, kalvali, sorkh dom, kamtarlan (k...

BACKGROUND Although blood pressure cuffs are commonly used and shared in medical facilities, their routine disinfection is performed infrequently. AIMS We investigated the contamination of blood pressure cuffs by methicillin-resistant Staphylococcus aureus (MRSA). METHODS The MRSA level on the inner side (the surface in contact with patients' skin) of blood pressure cuffs used in the wards ...

OBJECTIVE To investigate the potential role of blood pressure (BP) cuffs in the spread of bacterial infections in hospitals. DESIGN A comprehensive, prospective study quantitatively and qualitatively evaluating the bacterial contamination on BP cuffs of 203 sphygmomanometers in use in 18 hospital units from January through March 2003. SETTING A university hospital with surgical, medical, an...

Bulliform phytoliths play an important role in researching rice origins as they can be used to distinguish between wild and domesticated rice. Rice bulliform phytoliths are characterized by numerous small shallow fish-scale decorations on the lateral side. Previous studies have shown that domesticated rice has a larger number of these decorations than wild rice and that the number of decoration...

Title of Document: THE EFFECT OF SUNLIGHT ON DECORATION PLACEMENT AND MATING SUCCESS IN MALE SATIN BOWERBIRDS Archer Freni Larned, Master of Science 2012 Directed By: Dr. Gerald Borgia, Professor, Department of Biology Males of some bird species choose sunlit display sites to enhance their visual signal. Satin bowerbird (Ptilonorhynchus violaceus) males place colored decorations on their bower ...

results. A level of contamination reaching 100 or more colony-forming units per 25 cm was observed on 92 (45%) of inner sides and 46 (23%) of outer sides of 203 cuffs. The highest rates of contamination occurred on the inner side of BP cuffs kept in intensive care units (ICUs) (20 [83%] of 24) or on nurses’ trolleys (27 [77%] of 35). None of the 18 BP cuffs presumed to be clean (ie, those that ...

The aim of this study was to define the microcirculation of the normal rotator cuff during arthroscopic surgery and investigate whether it is altered in diseased cuff tissue. Blood flow was measured intra-operatively by laser Doppler flowmetry. We investigated six different zones of each rotator cuff during the arthroscopic examination of 56 consecutive patients undergoing investigation for imp...
