Haemorheological components in the pre-geriatric and geriatric age range in a randomly selected Western Sicily population sample (Casteldaccia study)

{Received 24.8.1992; accepted 7.12.1992} On a randomly selected western Sicily population sample (Casteldac­ cia Study: 600 subjects; 300 males and 300 females) of an age range from 40 to 79 years, were determined: Haematocrit (Htc) , blood vi­ scosity, plasma viscosity, filterability of whole blood and fibrinogen. Par­ ticipation was 97%, being 582 subjects (M = 287, F = 295). All the parameters measured showed a progressive increase with age and si­ gnificant differences were found between male and female subjects: Htc and blood viscosity were higher in male subjects (p < 0.01), while plasma viscosity, whole blood filterability and fibrinogen were higher in female subjects (p < 0.05).

Non lipid, dose-dependent effects of pravastatin treatment on hemostatic system and inflammatory response

Objectives: The aim of the present study was to evaluate the effects of pravastatin treatment on lipid, inflammation, and coagulation parameters in patients suffering from myocardial infarction with or without carotid atherosclerotic lesions (groups 1 and 2, respectively). Methods: In the first phase of the study, a cross-sectional comparison of lipid, inflammation, and coagulation parameters was performed between the patients and the control group (group 3). Highly significant differences in these parameters were observed, especially in group 1. In the second phase of the study, we assessed the effects of a persistent reduction in cholesterol synthesis induced by increasing doses of pravas…

All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems

Rapidly spinning neutron stars are promising sources of continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter under extreme conditions. A significant fraction of the known pulsar population belongs to binary systems. Searching for unknown neutron stars in binary systems requires specialized algorithms to address unknown orbital frequency modulations. We present a search for continuous gravitational waves emitted by neutron stars in binary systems in early data from the third observing run of the Advanced LIGO and Advanced Virgo detectors using the semicoherent, GPU-accelerated, binaryskyhough pipeline. The search analyzes the most s…

Improvement of fibrinolysis and plasma lipoprotein levels induced by gemfibrozil in hypertriglyceridemia.

A randomized double-blind study was carried out with gemfibrozil (600 mg b.i.d.) vs placebo in 20 patients (twelve males and eight females, age 52 +/- 3 years, BMI 24.2 +/- 0.4) suffering from primary hypertriglyceridemia (Fredrickson's type IV). Each group was treated for a 12 week period with gemfibrozil (n = 10) or placebo (n = 10) patients) in a double-blind fashion. Total cholesterol, HDL-cholesterol (HDL-C) and its subfractions (HDL2-C and HDL3-C), blood glucose, Apolipoproteins A1 and B, fibrinogen, plasminogen, factor VII, t-PA:Ag and PAI activity pre- and post-venous occlusion (VO) were determined. In the gemfibrozil-treated group a significant decrease of total cholesterol and tri…

Search for anisotropic gravitational-wave backgrounds using data from Advanced LIGO and Advanced Virgo's first three observing runs

We report results from searches for anisotropic stochastic gravitational-wave backgrounds using data from the first three observing runs of the Advanced LIGO and Advanced Virgo detectors. For the first time, we include Virgo data in our analysis and run our search with a new efficient pipeline called {\tt PyStoch} on data folded over one sidereal day. We use gravitational-wave radiometry (broadband and narrow band) to produce sky maps of stochastic gravitational-wave backgrounds and to search for gravitational waves from point sources. A spherical harmonic decomposition method is employed to look for gravitational-wave emission from spatially-extended sources. Neither technique found eviden…

Effects of moderate Sicilian red wine consumption on inflammatory biomarkers of atherosclerosis.

Objective: The aim of the study is to evaluate the effect of moderate Sicilian red wine consumption on cardiovascular risk factors and, in particular, on some inflammatory biomarkers. Methods: A total of 48 subjects of both sexes who were nondrinkers or rare drinkers of moderate red wine were selected and randomly subdivided into two groups assigned to receive with a crossover design a Sicilian red wine (Nero d’Avola or Etna Torrepalino) during meals: Group A (n ¼ 24), in whom the diet was supplemented for 4 weeks with 250 ml/day of red wine, followed by 4 weeks when they returned to their usual wine intake; and Group B (n ¼ 24), in whom the usual wine intake was maintained for 4 weeks, fol…

Per un corpus dei marchi di cava punici e neopunici nell’edilizia della Tunisia. Prime note

Le ricerche avviate in Tripolitania (Leptis Magna e Sabratha) sulla tradizione edilizia locale esaminata attraverso i marchi di cava punici e neopunici hanno coinvolto altre regioni del Mediterraneo e più recentemente alcuni siti archeologici della Tunisia. Nel corso delle due prime campagne (2017, 2018) l’interesse si è concentrato sulle aree archeologiche di Cartagine e su alcuni siti di Capo Bon. Ci si propone di redigere un corpus dei marchi di cava, scarsamente documentati o inediti, al fine di incrementare il repertorio oggi noto e di porlo in relazione alle tecniche costruttive di tradizione punica. Presentiamo una breve rassegna della documentazione epigrafica raccolta e una sintesi…

Elevated levels of lipoprotein (a) in patients suffering from myocardial infarction with carotid atherosclerotic lesions.

The aim of the present study was to evaluate metabolic, coagulation and fibrinolytic parameters in 45 patients [31 men, 14 women, aged 56.5 +/- 3.5 years (mean +/- SD)] who had suffered myocardial infarction more than 6 months earlier, with or without carotid atherosclerotic lesions. After the extracranial carotid arteries had been evaluated using a B-mode Duplex scanning system, patients were subdivided into two groups: group 1 (n = 20) with carotid plaques or measurable intima-media thickness; and group 2 (n = 25) without carotid plaques or measurable intima-media thickness. Twenty-two age- and sex-matched subjects were recruited as controls (group 3). Groups 1 and 2 displayed significant…

Fibrinolysis in hypertriglyceridaemic subjects in response to venous occlusion.

We have measured various fibrinolytic and coagulation parameters (t-PA antigen, PAI, fibrinogen, plasminogen and factor VII) before and after 10 min of venous occlusion in 20 hypertryglyceridaemic subjects (twelve males and eight females, age 38 +/- 4 years, body mass index 23 +/- 1.5) and 20 healthy normal subjects, matched for sex (twelve males and eight females), age (37 +/- 3.5 years) and body mass index (22.8 +/- 1.4). At rest, t-PA:Ag, PAI, fibrinogen, plasminogen and factor VII were significantly (P < 0.005) higher in hypertriglyceridaemic subjects than in normal controls. After venous occlusion, the increase in all parameters except t-PA:Ag was more marked in the patient group than …
