Oral bisphosphonates comprise the most widely prescribed class of antiosteoporotic drugs. Recent reports, however, suggest a link between prolonged bisphosphonate use and atypical low-energy, subtrochanteric fractures. We describe the clinical course of two patient treated for a long term with different bisphosphonates who developed subtrochanteric atypical fractures. They were treated initiall...
Difficulties in evaluating the anticoagulant effect of heparin led to studies of the rate of disappearance of its effect on the whole body partial thromboplastin time, and of its simultaneously bioassayed plasma concentration. The slope of the anticoagulant's dose-effect curve varied with each subject's baseline coagulation status, which probably accounts for the wide range of clinically observ...
The discourses of Antillanité and Créolité are both based on the absence of women. This is more important in the discourse of Créolité since it silences the grandmothers, great aunts and village midwives who are the transmitters of folk tales, folk medicines and oral culture. In the struggle for recognition between Caribbean males and western males folk medicine may be too closely associated wi...
It has been known for more than 40 years that images fade from perception when they are kept at the same position on the retina by abrogating eye movements. Although aspects of this phenomenon were described earlier, the use of close-fitting contact lenses in the 1950s made possible a series of detailed observations on eye movements and visual continuity. In the intervening decades, many invest...
(CS) and without (C) are shown. The numbers indicate those studies in which there was agreement in diagnosis. The table also shows the relationship of these three techniques to the final diagnosis (FD) made for the patient in each case. The final diagnosis made use of other information such as additional perfusion views, chest radiographs, and patient examination. Film (F) relates best to final...
Because of the massive amount of incoming visual information, perception is fundamentally selective. We are aware of only a small subset of our visual input at any given moment, and a great deal of activity can occur right in front of our eyes without reaching awareness. While previous work has shown that even salient visual objects can go unseen, here we demonstrate the opposite pattern, where...
For a two-phase (liquid-gas) two-component (water-hydrogen) system we discuss the formulation of the possible dissolution of hydrogen in the liquid phase. The problem is formulated as a set of nonlinear partial differential equations with complementary constraints and we show how Henry’s law fits in a phase diagram. Key-words: Porous media, two-phase flow, dissolution, nuclear waste underground...
The spontaneous disappearance of a hepatic cyst is described. A 62-year-old woman presented with symptoms of general fatigue in August 1992. Her past medical history was significant for chronic hepatitis, which was diagnosed in 1990 but not treated. Initial laboratory tests revealed mild liver dysfunction with a positive serologic test for hepatitis C. In August 1992, ultrasonography and comput...
We make an analysis of the fake CPT -violating asymmetries between the survival probabilities of neutrinos and antineutrinos, induced by the terrestrial matter effects, in three different scenarios of long-baseline neutrino oscillation experiments with L = 730 km, L = 2100 km and L = 3200 km. In particular, the dependence of those asymmetries on the Dirac-type CP -violating phase of the lepton ...
This Letter reports the first direct observation of muon antineutrino disappearance. The MINOS experiment has taken data with an accelerator beam optimized for ν(μ) production, accumulating an exposure of 1.71 × 10²⁰ protons on target. In the Far Detector, 97 charged current ν(μ) events are observed. The no-oscillation hypothesis predicts 156 events and is excluded at 6.3σ. The best fit to osci...
