Cycling training effects on fat metabolism blood parameters
BACKGROUND: Study the acute and middle term (4 weeks training) effect of cycling training on fat blood hematological parameters, urine, fatigue, and general health in recreational well-trained cyclists. METHODS: Nineteen cyclists underwent five blood sample collections: before and after an incremental maximal ramp test 7 days before day 0 (D-0); before and after 1 hour exhaustion trial test at baseline (D-0); and after 28 days of training (D-28). Age 34.5 years (\ub19.5); weight 74.87 kg (\ub16.6); height 177.3 cm (\ub15.2); BMI 26.3 (\ub14.9); VO2max 53.75 mL/kg/ min (\ub16.01); distance cycled 314.7 km/week (\ub1137.1). RESULTS: Acute effect was strong elevating WBC from 6.27\ub12.34 to 9.01\ub13.63
7103/\ub5L, an increase in LDL and total CHOL, in this respect, existing literature is controversial. No changes in body weight or blood pressure was observed after 1 month of regular training albeit lipid profile significantly improved, as well as GOT. CONCLUSIONS: Effect of a short incremental bout of exercise was to temporary elevated all the blood parameters except MCH and MCHC. A month of intensive training (distance cycled: 314.7\ub1137.1 km/week) significantly improved blood lipids profile with no permanent effect on WBC, blood pressure or body weight, but improved post effort lactate concentration and fatigue perception. Hematuria is confirmed to be a rare occurrence in recreational cyclists. Data can be useful for training monitoring and comparisons with similar groups of athletes, where there is a lack of information in literature and for comparing exercise effects
Do managerial skills matter? An analysis of the impact of managerial features on performance for the Italian football
This paper studies the impact of a set of managerial features on performance in the top division of the Italian football league during seasons 2000/01-2009/10. Our set of coach characteristics includes indicators of skill, experience, innate features as well as empathy with the team. We find that some managerial features matter even when we control by club power and past results. Indeed, performance is positively correlated with the fact that the manager has experience abroad or has been a previous player of the team but negatively correlated with lack of previous managerial experience. Other features affect only some particular aspects of performance. In particular, Italian managers play a more defensive game in home matches while old managers are more defensive in away games. Also, changing a coach within the season has a negative impact on the defensive skill of the team in away matches

Low threshold acquisition controller for Skipper charge-coupled devices
The development of the Skipper-charge-coupled devices (Skipper-CCDs) has been a major technological breakthrough for sensing very weak ionizing particles. The sensor allows to reach the ultimate sensitivity of silicon material as a charge signal sensor by unambiguous determination of the charge signal collected by each cell or pixel, even for single electron-hole pair ionization. Extensive use of the technology was limited by the lack of specific equipment to operate the sensor at the ultimate performance. A simple, single-board Skipper-CCD controller designed by the authors is presented and aimed for the operation of the detector in high sensitivity scientific applications. Our article describes the main components and functionality of the so-called low threshold acquisition controller together with experimental results when connected to a Skipper-CCD sensor. Measurements show unprecedented deep subelectron noise of 0.039 erms-/pix by nondestructively measuring the charge 5000 times in each pixel.Fil: Cancelo, Gustavo Indalecio.

SNPs Array Karyotyping Reveals a Novel Recurrent 20p13 Amplification in Primary Myelofibrosis
The molecular pathogenesis of primary mielofibrosis (PMF) is still largely unknown. Recently, single-nucleotide polymorphism arrays (SNP-A) allowed for genome-wide profiling of copy-number alterations and acquired uniparental disomy (aUPD) at high-resolution. In this study we analyzed 20 PMF patients using the Genome-Wide Human SNP Array 6.0 in order to identify novel recurrent genomic abnormalities. We observed a complex karyotype in all cases, detecting all the previously reported lesions (del(5q), del(20q), del(13q), +8, aUPD at 9p24 and abnormalities on chromosome 1). In addition, we identified several novel cryptic lesions. In particular, we found a recurrent alteration involving cytoband 20p13 in 55% of patients. We defined a minimal affected region (MAR), an amplification of 9,911 base-pair (bp) overlapping the SIRPB1 gene locus. Noteworthy, by extending the analysis to the adjacent areas, the cytoband was overall affected in 95% of cases. Remarkably, these results were confirmed by real-time PCR and validated in silico in a large independent series of myeloproliferative diseases. Finally, by immunohistochemistry we found that SIRPB1 was over-expressed in the bone marrow of PMF patients carrying 20p13 amplification. In conclusion, we identified a novel highly recurrent genomic lesion in PMF patients, which definitely warrant further functional and clinical characterization
Scenarios and use cases in Tweether:W-band for Internet Everywhere
—Millimeter waves offer a promising solution to the
data congestion that is fast overwhelming the actual network
capacity. While the V- band (57-64GHz) and E-band (71-76GHz
and 81-86 GHz) are widely targeted for Point to Point high data
rate, the W-band (92-95GHz) is still unexploited and lightly
regulated. In particular, Point to Multi-Point (PtMP) wireless
backhaul architecture could benefit from 3 GHz frequency
bandwidth at the W-band to achieve a capacity density up to 10
Gbps/km². The HORIZON 2020 TWEETHER project aims to
solve the technological gap that presently prevents the use of Wband
to distribute substantial capacity from a central point over
a wide coverage surface. Moreover, each of the links of the PtMP
TWEETHER system is conceived to provide a high level of
flexibility in order to easily adapt to a large panel of deployment
scenarios.The project has received funding from the European Union’s Horizon 2020 research and innovation programunder grant agreement no 644678.Paolini, C.; Letizia, R.; Ni, Q.; André, F.; Burciu, ,I.; Magne, F.; Rocchi, M....

Prevalence and Prognostic Role of IDH Mutations in Acute Myeloid Leukemia: Results of the GIMEMA AML1516 Protocol
IDH1/2 mutations are common in acute myeloid leukemia (AML) and represent a therapeutic
target. The GIMEMA AML1516 observational protocol was designed to study the prevalence
of IDH1/2 mutations and associations with clinico-biological parameters in a cohort of Italian AML
patients. We analyzed a cohort of 284 AML consecutive patients at diagnosis, 139 females and
145 males, of a median age of 65 years (range: 19–86). Of these, 38 (14%) harbored IDH1 and
51 (18%) IDH2 mutations. IDH1/2 mutations were significantly associated with WHO PS >2 (p < 0.001)
and non-complex karyotype (p = 0.021) when compared to IDH1/2-WT. Furthermore, patients with
IDH1 mutations were more frequently NPM1-mutated (p = 0.007) and had a higher platelet count
(p = 0.036). At relapse, IDH1/2 mutations were detected in 6 (25%) patients. As per the outcome,
60.5% of IDH1/2-mutated patients achieved complete remission; overall survival and event-free
survival at 2 years were 44.5% and 36.1%, respectively: these rates were similar to IDH1/2-WT. In
IDH1/2-mutated patients, high WBC proved to be an independent prognostic factor for survival.
In conclusion, the GIMEMA AML1516 confirms that IDH1/2 mutations are frequently detected at
diagnosis and underlines the importance of recognizing IDH1/2-mutated cases up-front to offer the
most appropriate therapeutic strategy, given the availability of IDH1/2 inhibitors
Exploring low-energy neutrino physics with the Coherent Neutrino Nucleus Interaction Experiment
The Coherent Neutrino-Nucleus Interaction Experiment (CONNIE) uses low-noise fully depleted charge-coupled devices (CCDs) with the goal of measuring low-energy recoils from coherent elastic scattering ( CE ν NS ) of reactor antineutrinos with silicon nuclei and testing nonstandard neutrino interactions (NSI). We report here the first results of the detector array deployed in 2016, considering an active mass 47.6 g (eight CCDs), which is operating at a distance of 30 m from the core of the Angra 2 nuclear reactor, with a thermal power of 3.8 GW. A search for neutrino events is performed by comparing data collected with the reactor on (2.1 kg-day) and reactor off (1.6 kg-day). The results show no excess in the reactor-on data, reaching the world record sensitivity down to recoil energies of about 1 keV (0.1 keV electron equivalent). A 95% confidence level limit for new physics is established at an event rate of 40 times the one expected from the standard model at this energy scale. The results presented here provide a new window to low-energy neutrino physics, allowing one to explore for the first time the energies accessible through the low threshold of CCDs. They will lead to new constraints on NSI from the CEνNS of antineutrinos from nuclear reactors.Fil: Aguilar Arevalo, Alexis.

Search for coherent elastic neutrino-nucleus scattering at a nuclear reactor with CONNIE 2019 data
The Coherent Neutrino-Nucleus Interaction Experiment (CONNIE) is taking data
at the Angra 2 nuclear reactor with the aim of detecting the coherent elastic
scattering of reactor antineutrinos with silicon nuclei using charge-coupled
devices (CCDs). In 2019 the experiment operated with a hardware binning applied
to the readout stage, leading to lower levels of readout noise and improving
the detection threshold down to 50 eV. The results of the analysis of 2019 data
are reported here, corresponding to the detector array of 8 CCDs with a
fiducial mass of 36.2 g and a total exposure of 2.2 kg-days. The difference
between the reactor-on and reactor-off spectra shows no excess at low energies
and yields upper limits at 95% confidence level for the neutrino interaction
rates. In the lowest-energy range, 50-180 eV, the expected limit stands at 34
(39) times the standard model prediction, while the observed limit is 66 (75)
times the standard model prediction with Sarkis (Chavarria) quenching factors.Comment: 23 pages, 14 figure
