Nanometer-sized conjugated 1,4- and 1,3,5-ethynylphenyl oligomers were synthesized starting from 3,5-di(trimethylsilylethynyl)phenylacetylene and p-[3,5-di(trimethylsilylethynyl)-1-ethynylphenyl]phenyl acetylene by cross-coupling reaction with a convenient haloaryl derivative, catalyzed by palladium(II)/copper(I), in excellent yield. The terminal acetylenes(More)
Allergic skin tests have to be performed 4-6 weeks after an allergic anesthetic reaction. Patients with allergic reactions during anesthesia were prospectively included (n = 44). Skin tests were performed in two stages: (i) Stage 1 (S1), 0-4 days after the reaction; and (ii) Stage 2 (S2), 4-8 weeks after. Five (11.5%) surgical procedures were suspended due(More)
UNLABELLED Anaesthetic hypersensitivity reactions can be IgE- or not IgE-mediated and are a challenge to find the causal agent. Histamine and tryptase determination are classically considered useful in the diagnosis of these reactions. The aim of our study was to assess the diagnostic usefulness of plasma histamine and different cut-off points of serum(More)
Cold urticaria is one of the least common types of urticaria, affecting approximately 1% to 3% of all patients with urticaria [1]. Patients present generalized or local wheal lesions in areas that come into contact with cold stimuli such as cold air, water, or objects. The symptoms may or may not be accompanied by angioedema. Cold urticaria can be primary(More)
Cork manufacturing is a traditional industry in Southern Europe, being the main application of this natural product in wine stoppers and insulation. Cork processing begins at boiling the raw material. As a consequence, great volumes of dark wastewaters, with elevated concentrations of chlorophenols, are generated, which must be depurated through costly(More)
To explore whether cognitive impairment and global functioning can predict the degree of insight into illness as well as whether insight is mediated by specific symptom dimensions of psychopathology in schizophrenia. A dimensional/cross sectional approach was used. A mixed group of clients (n = 36) were assessed as part of a routine clinical evaluation. The(More)
Scientific and technological expertise is currently experiencing a crisis. The public shows a growing distrust in many aspects related to the techno-scientific development. The birth of that suspicion begins after World War II but has transformed in the past few decades. In this paper, the authors examine how that doubt has specific features in the present(More)
We describe the case of a patient with severe lactic acidosis, as well as presenting some data on its incidence, diagnosis, prognostic factors, and the most appropriate treatment. A 76 year-old male patient with diabetes on treatment with metformin, hypertension, dyslipaemia, and with mild cognitive impairment, was admitted to the Intensive Care Unit in a(More)
The use of hand rub to obtain maximum decrease in bacterial load is important because the reduction needed to avoid transmission is unknown. The monomer of 2-butanone peroxide is a peroxygen derivative with potential biocidal use in hospitals. The aim of this study was to compare the efficacy of hand rub with an alcoholic solution of peroxide 2-butanone(More)
