Figure 2 Glove stretched over the retractor, providing a seal Figure 3 Glove port with camera inserted removal (Fig 1). This technique can also be used at a stoma site. Once the specimen is removed, stretch a sterile size 61⁄2 glove over the retractor and re-establish pneumoperitoneum. A perfect seal will be obtained (Fig 2). If the port is still required, cut the tip off any finger of the glov...

In this study, minimum audible angles (MAAs) of aerial pure tones were measured in and compared between a northern elephant seal (Mirounga angustirostris), a harbor seal (Phoca vitulina), and a California sea lion (Zalophus californianus). Testing was conducted between 0.8 and 16 kHz in the elephant seal and 0.8 and 20 kHz in the harbor seal and sea lion in a hemi-anechoic chamber using a left/...

PURPOSE Sealants form a physical barrier between the oral environment and deep fissures that contribute to caries prevention. It is postulated that sealants possessing antibacterial properties are advantageous. The purpose of this study was to evaluate the antibacterial properties of four pit and fissure sealants using direct contact test (DCT) and agar diffusion test (ADT). METHODS For the D...

ffects of pressure ratio and rotational speed on the leakage flow nd cavity pressure characteristics of the rotating staggered labyinth seal were investigated by means of experimental measureents and numerical simulations. The rotating seal test rig with urbine flowmeter and pressure measuring instruments was utiized to investigate the leakage flow of the staggered labyrinth eal at eight pressu...

This study aimed to compare the effects of ethylenediaminetetraacetic acid (EDTA) and maleic acid (MA) on the sealing ability of various root canal sealers. Eighty root canals were instrumented and irrigated with either EDTA or MA. They were divided into eight experimental groups and obturated as follows: Group 1: MA + Hybrid Root SEAL/gutta-percha. Group 2: EDTA + Hybrid Root SEAL/gutta-percha...

Planar patch-clamp is a two-dimensional variation of traditional patch-clamp. By contrast to classical glass micropipette, the seal quality of silicon patch-clamp chips (i.e. seal resistance and seal success rate) have remained poor due to the planar geometry and the nature of the substrate and thus partially obliterate the advantages related to planar patch-clamp. The characterization of physi...

The hemoglobins of seven species of pinnipeds-elephant, ribbon, fur, harbor, and grey seals, walrus, and California sea lion-had two major and one minor hemoglobin fractions on electrophoresis at pH 8.6. One of the major fractions in all seven species had the same electrophoretic mobility. The second fractions of the gray, harbor, and ribbon seals were similar, but different from the second fra...

The Canadian seal hunt is the world’s largest commercial slaughter of marine mammals and, as such, has been the subject of veterinary scrutiny for half a century. In that time, veterinary experts have made multiple recommendations to improve welfare at the seal hunt, some of which have been included in Canadian sealing regulations. Yet analysis of video material and studies on the outcomes of t...

A retrospective survey was performed on the presenting conditions of 205 live grey seal pups (Halichoerus grypus) admitted to the Cornish Seal Sanctuary in Gweek, United Kingdom between May 2005 and March 2011. The purpose of the survey was to examine the prevalence of various presenting signs at the sanctuary. The presenting signs were classified into nine non-mutually exclusive categories: oc...
