Abstract
This article describes a dataset of acceleration signals acquired from a low-cost Wireless Sensor Network (WSN) during seismic events that occurred in Central Italy. The WSN consists of 5 low-cost sensor nodes, each embedding an ADXL355 tri-axial MEMS accelerometer with a fixed sampling frequency of 250 Hz. The data was acquired from February 2023 to the end of June 2023. During this period, several earthquake sequences affected the area where the sensor network was installed. Continuous data was acquired from the WSN and then trimmed around the origin time of seismic events that occurred near the installation site, close to the city of Pollenza (MC), Italy. A total of 67 events were selected, whose data is available at the Istituto Nazionale di Geofisica e Vulcanologia (INGV) Seismology data center. The traces acquired from the WSN were then manually annotated by analysts from INGV. Annotations include picking time for P and S phases, when distinguishable from the background noise, alongside an associated uncertainty level for the manual annotations. The resulting dataset consists of 328 3 × 25,001 arrays, each associated with its metadata. The metadata includes event data (hypocenter position, origin time, magnitude, magnitude type, etc.), trace-related data (mean, median, maximum, and minimum amplitudes, manual picks, and picks uncertainty), and sensor-specific data (sensor name, sensitivity, and orientation). Furthermore, a small dataset consisting of non-seismic traces is included, with the goal of providing records of noise-only traces, relative to both electronic and environmental/anthropic noise sources. The dataset holds potential for training and developing Machine Learning or signal processing algorithms for seismic data with low signal-to-noise ratios. Additionally, it is valuable for research about earthquakes, structural health monitoring, and MEMS accelerometer performance in civil and seismic engineering applications.

Abstract
The aim of our prospective, randomised, controlled and open-label clinical study was to evaluate in healthy post-menopausal women the effects of raloxifene (RLX) on body fat distribution and lipids, and the correlations between these parameters. The fat distribution, by dual energy X-ray absorptiometry, and lipids were evaluated at baseline and after 1 yr in 50 post-menopausal women: 25 were treated with RLX 60 mg/die, while 25 served as control group (CG). After 1 yr, we observed in RLX-users a slight reduction of fat mass in trunk and central region and an increase in legs and, in relation to CG, significantly lower values of adiposity in trunk and abdominal region (p < 0.05). At the same time, HDL-cholesterol (HDL-C) and apolipoprotein A1 (ApoA1) were significantly increased in relation to baseline values and CG (p < 0.05) and apolipoprotein B (ApoB), total cholesterol/HDL-C, LDL cholesterol/ HDL-C, and ApoB/ApoA1 ratios significantly decreased compared to baseline values and CG (p < 0.05). No correlation was underlined among lipids and regional fat distribution. These results highlight the positive effect of RLX on lipids and suggest, for the first time, that RLX promotes the shift from android to gynoid fat distribution, and prevents the uptrend of abdominal adiposity and body weight compared with untreated women.

Abstract
BACKGROUND Following bioprosthetic failure, replacement is usually done with mechanical valves to avoid repeated reoperations. METHODS From 1986 to 1996 we operated on 130 patients with bioprosthetic failure, implanting a new bioprosthesis; this group included patients with contraindication to anticoagulation, tricuspid replacement, and specific patient requests. Mean age was 63+/-8 years. RESULTS The perioperative mortality was 13.8%. At 10 year follow-up the actuarial estimate of survival was 77.4%+/-6.6%. Freedom from structural valve deterioration was estimated at 81.8%+/-6.3%. Freedom from a third operation was estimated at 85.5%+/-5.2%. No patient was permanently anticoagulated. Freedom from thromboembolism was estimated at 91.5%+/-4%, and there were no hemorrhages. Freedom from cardiac-related deaths was estimated at 85.7%+/-5%. CONCLUSIONS This group of patients received the first valve between 1976 and 1986; the range of the cumulative follow-up reaches 20 years, and the extended survival compares favorably with survival of mechanical valves.

Abstract
BACKGROUND Left ventricular dysfunction is frequently observed in patients after hypothermic cardioplegic arrest, and often inotropic intervention is necessary for patients to be successfully weaned from cardiopulmonary bypass (CPB). A myocardial beta-adrenergic receptor (beta AR) desensitization has been noted to occur after hypothermic CPB in patients undergoing coronary artery bypass grafting. This randomized study was undertaken to determine the effect of cardioplegic solution temperature on cardiac beta ARs. METHODS Two groups of patients (20 patients in each) scheduled for elective coronary artery bypass grafting underwent CPB with either intermittent warm or cold blood cardioplegia. The density of the beta ARs, the proportion of beta 1- to beta 2-adrenergic receptors, and the beta AR coupling capacity to adenylate cyclase were determined in specimens of the right atrial tissue at baseline, during CPB, and after discontinuation of CPB. Plasma concentrations of catecholamines were also measured in both arterial and coronary sinus samples. RESULTS In both cardioplegia groups, no significant modification in either the beta AR density or the proportion of beta 1- to beta 2-adrenergic receptors was detected. However, a significant decrease in adenylate cyclase activity after stimulation with isoproterenol was observed in the cold blood cardioplegia group during CPB (p < 0.01) and 30 minutes after its discontinuation (p < 0.05). Moreover, a significant decrease in adenylate cyclase activity during CPB was detected in this group after stimulation with sodium fluoride (p < 0.05), but this pattern was found to be completely reversed by 30 minutes after discontinuation of CPB. No modification in the basal or stimulated adenylate cyclase activity was observed in the warm blood cardioplegia group during or after CPB. CONCLUSIONS Our results confirm the finding from previous studies of a cardiac beta AR desensitization after hypothermic cardioplegic arrest, and provide evidence of the advantages of intermittent warm blood cardioplegia in preserving the autonomic sympathetic function of the heart.

Abstract
OBJECTIVE Activation of both complement and neutrophils has been demonstrated to be involved in many pathological reactions following cardiopulmonary bypass (CPB). The aim of the present study is to evaluate the effect of normothermic and hypothermic CPB on both complement and neutrophil activation. METHODS Two groups of patients (n = 20 each) scheduled for elective coronary artery bypass grafting, underwent CPB with intermittent warm or cold blood cardioplegia. Plasma concentration of C3a, C5a and C5b-9, as well as nitro-blu tetrazolium (NBT) scores of circulating neutrophils were measured before anesthesia, 10 and 30 min after the beginning of CPB, and 8, 16 and 24 h, postoperatively. RESULTS In both groups, CPB determined a significant complement activation, evidenced as a significant increase in plasma concentration of C3a, C5a and C5b-9. This in turn triggered the neutrophil activation, documented as a significant increase of NTB scores in circulating neutrophils at the end of CPB and in the early postoperative period. Interestingly, in the warm group the extent of both complement and neutrophil activation was significantly higher compared with the cold group during the whole sampling period. CONCLUSION In conclusion, our study clearly demonstrates that warm CPB is associated with an increased ability to activate complement and neutrophils in patients undergoing coronary surgery.

Abstract
To evaluate the effect of coenzyme Q10 in reducing postoperative cardiac complications after ischemia and reperfusion, we randomly divided 40 patients undergoing elective coronary artery bypass into two groups: patients in group 1 received coenzyme Q10 (150 mg/day) for 7 days before operation, and those in group 2 were the control group. Concentrations of thiobarbituric acid-reactive substances (malondialdehyde), conjugated dienes, and cardiac isoenzymes of creatine kinase were measured in samples from both arterial and coronary sinus sites. Serial sampling was performed 5 minutes after heparin administration, at 10 and 30 minutes during cardiopulmonary bypass, 15 and 30 minutes after aortic cross-clamp removal, and 5 minutes after protamine administration. The concentrations of malondialdehyde, conjugated dienes, and creatine kinase in group 1 were significantly lower than those in group 2. The decrease in plasma malondialdehyde concentrations correlated positively with the decrease in creatine kinase levels in the coronary sinus. The treatment group showed a significantly lower incidence of ventricular arrhythmias during the recovery period than did the control group (p < 0.05). Although the percentage of patients requiring inotropic agents was not significantly different between the two groups, the mean dosage of dopamine required to maintain stable hemodynamics was significantly lower in patients of group 1 than in those of group 2 (p < 0.01). Our findings suggest that pretreatment with coenzyme Q10 may play a protective role during routine bypass grafting by attenuating the degree of peroxidative damage.

Abstract
Intraoperative thermographic evaluation of regional myocardial cooling induced by cardioplegia, in patients with coronary artery disease, was conducted in 22 cases. Pictures were obtained at the beginning of the cardiopulmonary by-pass, after general cooling and during cardioplegic infusion. Uneven myocardial cooling was observed related to the degree of coronary artery stenosis. After the distal anastomosis of the saphenous vein by-pass graft was completed, injection of cold solution in to the graft showed marked cooling of the dependent myocardium, proving the patency of the graft. In the case of internal mammary artery graft (IMA), after the anastomosis was completed, releasing the bull-dog clamp on the IMA graft, allowed a flow of relatively warm (30 degrees C) blood in the anterolateral wall of the cold (20 degrees C) heart. A warm spot appeared in the thermographic pictures, assessing the patency of the IMA graft. Thermography appears to be a useful tool during myocardial revascularization in order to assess proper myocardial cooling during cardioplegia, and to check intraoperative patency of saphenous vein graft and IMA graft. The use of a special mirror prevents interference with the surgeon's work.

Abstract
We studied 76 patients with congenital heart disease, whose ages ranged from 2 to 39 years. The following investigations were carried out pre-operatively and post-operatively in all patients: visual acuity, cycloplegic refraction, orthoptic examination, examination of the fundus. Where collaboration was sufficient the following were also studied: kinetic and static perimetry, adaptation perimetry, colour vision, electroretinography. There were no differences before and after operation of visual acuity, adaptation perimetry, refraction, electroretinography or of the fundus. Post-operative changes were only found in 4 of the 65 patients in whom perimetry was performed. By comparison, an identical study of patients with acquired heart disease showed the percentage of functional ocular changes to be higher in this group.
