La alternancia de la oratio recta y de la oratio obliqua en los discursos intercalados de la historiografía romana
2009
Siguiendo la tradición griega, los historiadores romanos incluían en sus obras desarrollos oratorios de sus personajes, alternando la oratio recta, que reproducía de forma supuestamente literal las palabras de los protagonistas, y la oratio obliqua, caracterizada por la reubicación del discurso en relación a las coordinadas espacio-temporales de su propio enunciado. Este método de reproducción discursivo tuvo un desarrollo inusitado en la lengua latina por no necesitar un verbo introductor ante cada nuevo enunciado. Un repaso de la historiografía romana permite entrever las evidentes diferencias de uso entre las diversas épocas y los diferentes historiadores: algunos no incluyeron en sus ob…
Resting Energy expenditure in type 2 diabetic patients and the effect of insulin bolus
2014
Aims: Resting energy expenditure (REE) plays a critical role in the regulation of body weight, with important implications in type 2 diabetes (T2D). However, the relationships between REE and T2D have not been extensively evaluated. We compared REE in persons with diabetes and in persons without diabetes. We also investigated the acute effect of insulin on REE and venous lactate, the latter an indirect measure of neoglucogenetic activity. Methods: REE was measured using indirect calorimetry in 14 newly diagnosed, untreated T2D adults and in 14 non-diabetic age-, gender- and body mass index-matched persons. The REE and lactate venous concentrations were also measured in a subgroup of 5 T2D p…
Non-alcoholic fatty liver disease is associated with higher metabolic expenditure in overweight and obese subjects: A case-control study
2019
Non-alcoholic fatty liver disease (NAFLD) is a common condition in Western countries. However, their metabolic characteristics are poorly known even though they could be important. Therefore, the objective of this study was to measure resting metabolic parameters in overweight/obese adults with hepatic steatosis compared to controls, matched for age, sex, and obesity level. Hepatic steatosis was diagnosed with liver ultrasound. Energy metabolism was measured with indirect calorimetry: energy expenditure (REE), predicted REE, the ratio between REE and the predicted REE, and the respiratory quotient (RQ) were reported. We measured some anthropometric, body composition, and bio-humoral paramet…
PREVALENCE OF ANTIBODIES ANTI-BARTONELLA HENSELAEIN WESTERN SICILY: CHILDREN, BLOOD DONORS, AND CATS
2011
To evaluate seroprevalence of B. henselae infection both in Sicilian children and healthy blood donors. Furthermore, circulation of Bartonella in the natural reservoir was also studied. Two hundred forty-three children, living in Sicily (Palermo), affected by various diseases, without clinical features suggesting B. henselae infection, together with 122 healthy blood donors were serologically investigated for IgG and IgM antibodies by indirect fluorescent antibody test (IFAT). One hundred twenty stray and 62 pet cats were also analyzed only for IgG. Among children 25.1% had IgG antibodies to B. henselae; 18.5% showed a titer 1:64, 2.4% 1:128, 2.4% 1:256, 0.8% 1:512, 0.4% 1:1024, and 0.4% 1:…
Screening for Autoantibodies to Tissue Transglutaminase Reveals a Low Prevalence of Celiac Disease in Blood Donors with Cryptogenic Hypertransaminase…
2001
Patients with chronic cryptogenic hypertransaminasemia are at high risk of developing celiac disease (CD). In fact, among the various serological disorders, CD patients at onset frequently present hypertransaminasemia. In this study, we evaluated usefulness and reliability of the new test for antitissue transglutaminase (tTG) in screening for CD as well as in estimating the prevalence of CD in a population of blood donors presenting unexplained hypertransaminasemia at donation. Controls were 180 consecutive healthy donors without hypertransaminasemia and 20 CD patients with known antiendomysial antibody (EmA) positivity. Out of 22,204 blood donors over a period of 2 years, we found 258 subj…
Actin is a target antigen of anti-neutrophil cytoplasmic antibodies (ANCA) in autoimmune hepatitis type-1.
1997
Abstract Background/Aim: Anti-neutrophil cytoplasmic antibodies (ANCA) are a group of autoantibodies first associated with Wegener's granulomatosis and microscopic polyangiitis. The signifiance of ANCA in autoimmune hepatitis remains uncertain; the nature of the antigen or antigens has not been defined yet. The purpose of this study was to identify the target antigen of ANCA in patients with autoimmune hepatitis. Method/Results: Sera from 32 type-1 autoimmune hepatitis patients were used in the present study. ANCA were detected in 24 of 32 sera (75%). A diffuse cytoplasmic staining pattern (C-ANCA) was detected in 14 patients; the P-ANCA pattern was observed in 10 patients. An extract of hu…
Analysis of seroprevalence against Coxiella burnetii in a sample of farm workers in Western Sicily
2016
Introduction and objective. Little is known about the development of chronic Q fever caused by Coxiella burnetii in occupational risk groups and in the general population in Italy, as well as in many countries in the world. The aim of this study was to highlight the presence of the infection in a sample of workers operating outdoors (but not directly in contact with animals), in three provinces of western Sicily, in order to detect the human seroprevalence and compare the obtained data with those found in animals raised in the same territory. Materials and methods. The study included 126 generic seasonal agricultural workers (labourers), 84 male and 42 female; none of whom were aware of any…
Low relative resting metabolic rate and body weight gain in adult Caucasian Italians
2005
OBJECTIVE: To investigate the relationship between resting metabolic rate (RMR) and subsequent changes in body size and degree of fatness in a group of adult Caucasian Italians. DESIGN: Prospective, longitudinal, observational study. SUBJECTS: In total, 155 subjects (72 males and 83 females, age range: 18–55 y; BMI: 17.5–63.4 kg/m2) were evaluated. In total, 43 (26 m and 17 f; BMI: 28.971.1 kg/m2, mean7s.e.m.) of them were reassessed 10–12 y later. MEASUREMENTS: Anthropometric and body composition (bioimpedance analysis) parameters and RMR (indirect calorimetry) were taken at baseline and after 10–12 y. RESULTS: Subjects (15 m, 8 f) who gained body weight (arbitrarily defined as a change in…
Antibody response to human cytomegalovirus (HCMV) glycoprotein B (gB) in AIDS patients with HCMV end-organ disease
1998
Human cytomegalovirus (HCMV)-specific antibody responses in HIV-1 infected individuals either with or without HCMV end-organ disease were examined to determine the whether development of HCMV disease was associated with a particular deficit in the antibody response. Antiwhole HCMV, anti-glycoprotein B (gB), and neutralizing antibody levels were higher in HIV-1 infected individuals than in healthy immunocompetent subjects, particularly in patients with AIDS either with or without HCMV-associated disease. Irrespective of location and spread of HCMV disease, patients who had received anti-HCMV therapy prior to sampling exhibited significantly higher anti-gB and neutralizing antibody titers tha…
Effects of gender on resting leg blood flow: implications for measurement of regional substrate oxidation.
1998
Jensen, Michael D., Tu T. Nguyen, A. Hernández Mijares, C. Michael Johnson, and Michael J. Murray. Effects of gender on resting leg blood flow: implications for measurement of regional substrate oxidation. J. Appl. Physiol. 84(1): 141–145, 1998.—These studies were designed to examine whether the respiratory quotient (RQ) of leg tissue (primarily skeletal muscle) would increase to a greater degree in women than in men during meal ingestion. We found that mean leg and systemic RQ values were similar in men under both basal and fed conditions, whereas the agreement was poor in women. In women, leg RQ values tended to be greater than the systemic RQ, whereas splanchnic RQ values tended to be l…
