Permanent implant of sealed radioactive sources is an effective technique for treating cancer. Typically, the radioactive sources are implanted in and near the disease, depositing radiation absorbed dose locally over several months. There may be instances where these patients must undergo unrelated surgical procedures when the radioactive material remains active enough to pose risks. This work ...
Two methods commonly used to quantify ectoparasites on live birds are visual examination and dust-ruffling. Visual examination provides an estimate of ectoparasite abundance based on an observer's timed inspection of various body regions on a bird. Dust-ruffling involves application of insecticidal powder to feathers that are then ruffled to dislodge ectoparasites onto a collection surface wher...
Does technological change amount to accumulation of general, and so transferable, human capital? To approach this question I rely on a theoretical framework in which the “technology distance” between industries reduces inter-industry transferability of workers’ skill. Empirically, I use US panel data on individual intra-industry and inter-industry mobility decisions between 1982 and 1990, a per...
1. Patches of stable substratum in streams may be important refugia for benthic organisms during scouring floods. Streambed stone stability, packing and embeddedness were assessed within and adjacent to beds of the macrophyte Justicia americana in five Alabama streams. 2. The force needed to dislodge stones and embeddedness was about two times lower outside Justicia beds than within them. Signi...
STUDY OBJECTIVE Standard length (3 to 5 cm) intravenous catheters in the deep brachial or basilic vein tend to dislodge prematurely. We assess the safety and longevity of a 15-cm catheter inserted in these veins by a novel ultrasonographically guided technique. METHODS This is a prospective cohort study conducted in an urban teaching emergency department (ED). Adult subjects were enrolled if ...
The chromodomain (CD) is a highly conserved motif present in a variety of animal and plant proteins, and its probable role is to assemble a variety of macromolecular complexes in chromatin. The importance of the CD to the survival of mammalian cells has been tested. Accordingly, we have ablated CD function using two single-chain intracellular Fv (scFv) fragments directed against non-overlapping...
Sterile elastic exsanguination tourniquets (HemaClear; OHK Medical Devices, Haifa, Israel) are relatively new on the market but are widely used because of the ease and speed of their application. The sterile elastic exsanguination tourniquet consists of a silicon ring wrapped in a stockinet sleeve with pull straps. The physician places the ring on the patient's fingers or toes and then pulls th...
To generate a cytopathic effect, the catalytic A1 subunit of cholera toxin (CT) must be separated from the rest of the toxin. Protein disulfide isomerase (PDI) is thought to mediate CT disassembly by acting as a redox-driven chaperone that actively unfolds the CTA1 subunit. Here, we show that PDI itself unfolds upon contact with CTA1. The substrate-induced unfolding of PDI provides a novel mole...
BACKGROUND & OBJECTIVES To evaluate the retention of complete cast crowns in teeth with adequate and inadequate crown height and to evaluate the effects of auxiliary retentive features on retention form complete cast crowns. MATERIALS AND METHODS Sixty freshly extracted human premolars. They were divided into 2 major groups depending upon the height of the teeth after the preparation. Group1 ...
INTRODUCTION The present study identified the triatomines collected in intra and peri-domestic environments, observed the occurrence of Trypanosoma cruzi infection in triatomines and correlated this information with housing conditions and the fauna associated with the rural areas of the City of Itabaianinha, located in the State of Sergipe, Brazil. METHODS Quarterly visits were conducted betw...
