There are no reports regarding pneumomediastinum caused by thoracic epidural block complications. We believe that it is possible to experience an occurrence of pneumomediastinum caused by air in the epidural space after performing a thoracic epidural block using the loss of resistance (LOR) technique with air. We report a witnessed case where pneumomediastinum appeared after a thoracic epidural...

We have compared skin to epidural space distance (SED) and tip to tip distance (TTD), a measure of posterior epidural space depth (PESD), in 40 patients with a 27-gauge Whitacre needle after identification of the epidural space using the hanging drop (HD) or loss of resistance (LOR) to air technique. After the LOR technique, TTD was found to be 2 mm greater than that after the HD technique, whe...

Although different studies have investigated career choices as cognitive acts of decision-making, non-cognitive components also play an important role. The study tries to develop an empirically based model of career decision-making process linking cognitive (search for work self-efficacy - SWSE) and non-cognitive (psychological well-being - PWB) components. In particular, the study investigates...

The aim was to enhance the dissolution of lornoxicam (LOR) and to produce mini-tablets with an optimised system to provide a rapid-release multi-particulate formulation. LOR systems were prepared through co-evaporation with either polyethylene glycol 6000 or Pluronic(®) F-68 (PLU) and adsorption onto Neusilin(®) US2 alone or co-adsorption in the presence of different amounts of polysorbate 80. ...

We introduce a new framework for Property Checking (PC) of sequential circuits. It is based on a method called Logic Relaxation (LoR). Given a safety property, the LoR method relaxes the transition system at hand, which leads to expanding the set of reachable states. For j-th time frame, the LoR method computes a superset Aj of the set of bad states reachable in j transitions only by the relaxe...

The vertebrate rod and cone photoreceptors are highly specialized sensory neurons that transduce light into the chemical and electrical signals of the nervous system. Although the physiological properties of cones and rods are well known, only a handful of genes have been identified that regulate the specification of photoreceptor subtypes. Taking advantage of the mosaic organization of photore...

This paper proposes an information model for a registry of learning object repositories (LOR). This is a work in progress and will be used as a starting point for a discussion on LOR registries organized during the SE@M’08 workshop.

The biotech company Lorus has announced the enrollment of the first cancer patient in a Phase I clinical study evaluating its small molecule anticancer drug candidate LOR-253. The open-label, dose escalation study will enroll patients with advanced or metastatic solid tumors for which no effective therapy is currently available, or whose cancer has not responded to conventional or standard ther...

This study examined whether air or saline, used for the loss-of-resistance (LOR) technique, resulted in a difference in pain relief or adverse events for laboring parturients. Previous studies had mixed findings regarding the onset of analgesia and subsequent pain relief. Research questions were as follows: Is there difference in analgesic onset for patients receiving air vs saline during the L...
