et al. Randomized clinical trial of three-layer paste and four-layer bandages for venous leg ulcers. Q Are 3 layer paste bandages as effective as 4 layer bandages for healing of venous leg ulcers? METHODS Design: randomised controlled trial. Setting: a hospital leg ulcer outpatient clinic in London, UK. Patients: 133 patients (56% men) with venous leg ulcers. Exclusion criteria: arterial diseas...

The repair of craniofacial bone defects is surgically challenging due to the complex anatomical structure of the craniofacial skeleton. Current strategies for bone tissue engineering using a preformed scaffold have not resulted in the expected clinical regeneration due to difficulty in seeding cells into the deep internal space of scaffold, and the inability to inject them in minimally invasive...

introduction: this study aimed to compare the marginal adaptation of new bioceramic materials, endosequence root repair material (errm putty and errm paste), to that of mineral trioxide aggregate (mta) as root-end filling materials. materials and methods: thirty-six extracted human single-rooted teeth were prepared and obturated with gutta-percha and ah-26 sealer. the roots were resected 3 mm f...

The date palm (Phoenix dactylifera L.) is one of the popular perennial fruit tree grown around world, particularly in West Asia and North Africa. Its (date) all throughout world. well-known for its beneficial health benefits regarded as a high-value commercial crop worldwide market. Dates are high-quality, low-cost source macro- micronutrients. Date fruits mostly composed carbohydrates, includi...

Personalized project space is an important feature in GPortal to support learning activities. Users in G-Portal are assigned unique usernames and can be members of one or more groups. Within a personalized project space, an owner user can create, delete, and organise metadata referencing learning objects on the Web. Browsing metadata and querying them are among the functions provided to access ...

Spreadsheets are the most popular live programming environments, but they are also notoriously fault-prone. One reason for this is that users actively rely on copy-paste to make up for the lack of abstraction mechanisms. Adding abstraction however, introduces indirection and thus cognitive distance. In this paper we propose an alternative: copy-paste tracking. Tracking copies that spreadsheet u...

AIM Long-term follow-up evaluations of pulpectomy in primary teeth have revealed retention of ZOE filling particles in the periapical area even after root resorption. CASE REPORT This paper reports a case of a child submitted to pulpectomy with ZOE paste in primary teeth. After 28 months, the filling particles remained, having migrated to the alveolar bone from the gingival vestibular mucosa ...

We study the convergence rate to stationarity for a class of exchangeable partitionvalued Markov chains called cut-and-paste chains. The law governing the transitions of a cut-and-paste chain is determined by products of i.i.d. stochastic matrices, which describe the chain induced on the simplex by taking asymptotic frequencies. Using this representation, we establish upper bounds for the mixin...
