BACKGROUND Anastomotic leakage is a major complication in colorectal surgery and with an incidence of 11% the most common cause of morbidity and mortality. In order to reduce the incidence of anastomotic leakage the C-seal is developed. This intraluminal biodegradable drain is stapled to the anastomosis with a circular stapler and prevents extravasation of intracolonic content in case of an ana...

objectives : the aim of this study was to compare apical sealing ability of alpha and beta phases of gutta-percha by means of bacterial leakage model. materials and methods: fifty single-rooted human premolars were selected. the root canals were prepared with mtwo rotary instruments up to apical #35.04. forty teeth were randomly divided into two groups (n= 20). the root canals were obturated by...

OBJECTIVES This study evaluated the marginal adaptation of composite indirect restorations bonded with dual curing resin cement after different strategies to seal dentin. Different bonding techniques associated or not with a low-viscosity composite resin (LVCR) were utilized. In addition, the bond strength between composite resin and pre-sealed dentin was evaluated in the buccal and pulpal wall...

UNLABELLED In case of severe dental erosion, the maxillary anterior teeth are often particularly affected. Restoring such teeth conventionally (ie, crowns) would frequently involve elective endodontic therapy and major additional loss of tooth structure. A novel, minimally invasive approach to restore eroded teeth has been developed and is currently being tested in the form of a prospective cli...

In the present work, fat, skin, liver and muscle samples from Leptonychotes weddellii (Weddell seal, n=2 individuals), Lobodon carcinophagus (crabeater seal, n=2), Arctocephalus gazella (Antarctic fur seal, n=3) and Mirounga leonina (southern elephant seal, n=1) were collected from King George Island, Antarctica, and analysed for POPs (PCBs, organochlorine pesticides and PBDEs) and stable isoto...

Abstract The distribution, density and percentage contribution of pack ice seals during ship-board censuses in the marginal sea zone beyond Lazarev Sea spring 2019 are presented. Adult/juvenile crabeater ( n = 19), leopard 3) Ross 10) were sighted 582.2 nm along ship’s track line area bounded by 00°00’–22°E 56°–60°S. Antarctic fur 21) only encountered on outer fringes ice, Weddell absent due to...

A comparison of identified faunal assemblages from the Dorset site of Phillip's Garden indicates that harp seal hunting was the main focus of activity throughout the site's occupation. Despite the highly specialized nature of site use, it appears that reliance on harp seal decreased over time while fish and birds became increasingly important. These changes may reflect longer seasonal occupatio...

A recent case of seal finger which was misdiagnosed and hence mistreated at the patient's first presentation is described. The patient was eventually referred to a hand specialist and after the correct treatment with tetracycline, responded well without any long-term sequelae. Seal finger is an occupational injury that occurs to those who work directly or indirectly with seals. The disease enti...

The interactive influence of furrow surface seal formation and surge irrigation (intermittent flow) on furrow infiltration into a Portneuf silt loam soil was measured with a recirculating infiltrometer. When the formation of a surface seal was prevented by a layer of cheesecloth laid on the furrow perimeter, flow interruption increased furrow bed bulk density by 100 kg/m 3 and decreased infiltr...
