E ndovascular management of symptomatic peripheral artery disease (PAD) remains challenging despite its adoption by many as the initial preferred revascularization strategy when anatomically feasible. A wide range of percutaneous therapies using a variety of endovascular devices, including percutaneous transluminal angioplasty (PTA), atherectomy, and stent placement, have been used; however, 5-...

This paper shows that preliminary injunctions may be sought in patent cases to obtain market power during the period of the injunction and are likely to be sought only where there is a small probability that the patent will be ultimately found valid. Both patentee and alleged infringer benefit from a preliminary injunction. This is an artifact of the asymmetry of current damage rules. Altering ...

We investigate how liability rules and property rules a ect the incentives to invest in research tools. We argue that it is hard to deter infringement under any of the enforcement regimes available. However, counterintuitively, a credible threat of infringement can actually be bene cial to the patentholder. We compare the two doctrines of damages under the liability rule, namely, lost pro t (lo...

Sustainable development must satisfy the needs of present generations without compromising the ability of future generations to meet theirs. Although it looks at the economic, environmental and social aspects of sustainability, this article focuses specifically on an analysis of the concept in conjunction with the use and protection of natural resources. It shows how taking account of environme...

PURPOSE This article describes (a) an immediate loading technique in the treatment of edentulous arches with screw-retained provisional restorations and (b) the effort to determine whether the described technique is compatible with the predictable achievement of osseointegration. MATERIALS AND METHODS Eight patients with either 1 or 2 edentulous arches were treated. A diagnostic tooth arrange...

BACKGROUND Acrylic and bisacryl resins are widely used both during the temporization phase as well as for provisional restorations and the effect of external agents on dentin sensitivity can be reduced by the obliteration of the tubules. OBJECTIVE The purpose of this study was to evaluate diffusion of methyl methacrylate monomer through dentin by high performance liquid chromatography (HPLC) ...

Provisional restorations are fabricated to protect the prepared tooth structure during the period between tooth preparation and insertion of the definitive restoration. These restorations are also referred to in the literature as interim, temporary, or provisional restorations (prostheses). Such restorations should be uncomplicated and inexpensive to fabricate in a short period of time. Several...

Computing the same perturbative S-matrix in quantum field theory, we may use various regularizations. They are all provisional in the sense that no trace of them is left in the final result. So they can provide no information about the physics of quantum scattering. We propose a new approach to the construction of the perturbative S-matrices. To this end we use non-provisional regularizations b...

pulpal health, waiting for gingival healing from periodontal and oral surgery, waiting for implants to integrate, and evaluating aesthetic and functional changes, to name a few. Some of the clinical requirements of provisional cements are: (1) good retention – it is desirable to have enough retention for long-term provisional cementation, yet not be so retentive that is difficult to remove the ...
