Effects of a 12-Week Suspension versus Traditional Resistance Training Program on Body Composition, Bioimpedance Vector Patterns, and Handgrip Strength in Older Men: A Randomized Controlled Trial

This investigation aimed to compare the effects of suspension training versus traditional resistance exercise using a combination of bands and bodyweight on body composition, bioimpedance vector patterns, and handgrip strength in older men. Thirty-six older men (age 67.4 ± 5.1 years, BMI 27.1 ± 3.3 kg/m2) were randomly allocated into suspension training (n = 12), traditional training (n = 13), or non-exercise (n = 11) groups over a 12-week study period. Body composition was assessed using conventional bioelectrical impedance analysis and classic and specific bioelectric impedance vector analysis, and handgrip strength was measured with a dynamometer. Results showed a significant (p < 0.05) group by time interaction for fat mass, fat-free mass, total body water, skeletal muscle index, classic and specific bioelectrical resistance, classic bioelectrical reactance, phase angle, and dominant handgrip strength. Classic and specific vector displacements from baseline to post 12 weeks for the three groups were observed. Handgrip strength increased in the suspension training group (p < 0.01, ES: 1.50), remained stable in the traditional training group, and decreased in the control group (p < 0.01, ES: -0.86). Although bodyweight and elastic band training helps to prevent a decline in muscle mass and handgrip strength, suspension training proved more effective in counteracting the effects of aging in older men under the specific conditions studied

Il Bacino di Acquatina (Frigole, Lecce), opportunità di ricerca sui sinkhole e implicazioni ecologiche

Lo sviluppo di doline da crollo nelle aree carsiche costiere ha un impatto significativo sull’ambiente naturale ed antropico determinando non solo cambiamenti nelle morfologie ma anche danni ingenti alle cose ed alle persone. Il Salento (Puglia meridionale) è un territorio che, in quanto costituito da rocce prevalentemente carbonatiche, è da sempre interessato da fenomeni di sprofondamento (sinkhole) i quali si manifestano solitamente con cedimenti improvvisi. Tra le zone più colpite vi è sicuramente quella adriatica leccese, compresa tra l’area delle Cesine a Sud e Casalabate a Nord: una fascia costiera estesa circa 35 km, caratterizzata da spiagge sabbiose di limitata estensione, delimitate lateralmente da piccoli promontori rocciosi e, nell’entroterra, da un sistema di dune, ampiamente erose dall’azione del mare e dalle attività antropiche. Questi sistemi di dune separano l’ambiente della spiaggia da vaste zone umide che occupano bassi morfologici più o meno stretti, allungati circa parallelamente alla linea di costa ed impostati in corrispondenza di depressioni tettoniche del substrato roccioso. Le aree umide sono state oggetto di interventi di bonifica svolti nella prima metà del secolo scorso e aventi l’obiettivo di debellare la malaria e restituire suolo utile per l’agricoltura. Negli anni 1960, e soprattutto nei decenni 1970 e 1980, queste aree, come tutte quelle costiere, sono state oggetto di un incontrollato sviluppo edilizio che ha portato a mascherare praticamente quasi del tutto le originarie depressioni. Il paesaggio originario è stato quindi frammentato e testimonianze delle aree umide presenti nei primi anni del 1900 si ritrovano esclusivamente in lembi variamenti estesi delle Cesine, di Acquatina e del Parco Regionale “Bosco e Paludi di Rauccio”. Le aree colmate sono invece sedi di allagamenti e dissesti che interessano anche l’edificato, con particolare riferimento a Casalabate, Torre Rinalda, Spiaggiabella e Torre Chianca. In questo lavoro si riportano i risultati preliminari di uno studio in atto sul bacino di Acquatina di Frigole (IT9150003), un sito di importanza comunitaria (SIC) dove negli ultimi 15 anni si sono formate numerose depressioni, il cui processo evolutivo è ancora in atto. Il bacino di Acquatina costituisce quindi un eccezionale laboratorio dove monitorare tali fenomeni e sviluppare modelli utili alla comprensione di ciò che avviene anche in altre aree, laddove le coperture antropiche rendono molto difficile fare studi di dettaglio

The structure of DNA by direct imaging

The structure of DNA was determined in 1953 by x-ray fiber diffraction. Several attempts have been made to obtain a direct image of DNA with alternative techniques. The direct image is intended to allow a quantitative evaluation of all relevant characteristic lengths present in a molecule. A direct image of DNA, which is different from diffraction in the reciprocal space, is difficult to obtain for two main reasons: the intrinsic very low contrast of the elements that form the molecule and the difficulty of preparing the sample while preserving its pristine shape and size. We show that through a preparation procedure compatible with the DNA physiological conditions, a direct image of a single suspended DNA molecule can be obtained. In the image, all relevant lengths of A-form DNA are measurable. A high-resolution transmission electron microscope that operates at 80 keV with an ultimate resolution of 1.5 Å was used for this experiment. Direct imaging of a single molecule can be used as a method to address biological problems that require knowledge at the single-molecule level, given that the average information obtained by x-ray diffraction of crystals or fibers is not sufficient for detailed structure determination, or when crystals cannot be obtained from biological molecules or are not sufficient in understanding multiple protein configurations

Usefulness of real time PCR for the differentiation and quantification of 652 and JP2 Actinobacillus actinomycetemcomitans genotypes in dental plaque and saliva

BACKGROUND: The aim of our study is to describe a fast molecular method, able to distinguish and quantize the two different genotypes (652 and JP2) of an important periodontal pathogen: Actinobacillus actinomycetemcomitans. The two genotypes show differences in the expression of an important pathogenic factor: the leukotoxin (ltx). In order to evidence this, we performed a real time PCR procedure on the ltx operon, able to recognize Aa clinical isolates with different leukotoxic potentials. METHODS: The specificity of the method was confirmed in subgingival plaque and saliva specimens collected from eighty-one Italian (Sardinian) subjects with a mean age of 43.9, fifty five (68 %) of whom had various clinical forms of periodontal disease. RESULTS: This procedure showed a good sensitivity and a high linear dynamic range of quantization (10(7)-10(2 )cells/ml) for all genotypes and a good correlation factor (R2 = 0.97–0.98). Compared with traditional cultural methods, this real time PCR procedure is more sensitive; in fact in two subgingival plaque and two positive saliva specimens Aa was only detected with the molecular method. CONCLUSION: A low number of Sardinian patients was found positive for Aa infections in the oral cavity, (just 10 positive periodontal cases out of 81 and two of these were also saliva positive). The highly leukotoxic JP2 strain was the most representative (60 % of the positive specimens); the samples from periodontal pockets and from saliva showed some ltx genotype for the same patient. Our experience suggests that this approach is suitable for a rapid and complete laboratory diagnosis for Aa infection

Social Design. Design e bene comune.

Per questo primo doppio numero della rivista, Social Design. Design e "bene comune", curato da Marinella Ferrara, Francesco E. Guida, Mario Piazza, Paola Proverbio e Raimonda Riccini, quasi come una sfida, si è provato a rompere l’ortodossia di un approccio lineare alla storia. In questo orientamento, che tende a portare più vicino a noi i temi storici, il Social Design si offre in modo calzante per il suo essere questione contemporanea e complessa, ampia e ambigua financo controversa, anche solo dal punto di vista delle diverse espressioni sinonimiche con cui si presenta: design etico, design umanitario, design per la collettività, design di pubblica utilità, design per l’utenza ampliata, design per la sostenibilità, ... Il numero ha ricevuto la Menzione d'Onore alla XXVII edizione del Compasso d'Oro (giugno 2022), ed è stato segnalato nell'ADI Design Index 2021 (promosso da ADI, Associazione per il Disegno Industriale) nella sezione "Ricerca teorica, storica, critica e progetti editoriali"

Data monitoring roadmap. The experience of the Italian Multiple Sclerosis and Related Disorders Register

Introduction Over the years, disease registers have been increasingly considered a source of reliable and valuable population studies. However, the validity and reliability of data from registers may be limited by missing data, selection bias or data quality not adequately evaluated or checked.This study reports the analysis of the consistency and completeness of the data in the Italian Multiple Sclerosis and Related Disorders Register.MethodsThe Register collects, through a standardized Web-based Application, unique patients.Data are exported bimonthly and evaluated to assess the updating and completeness, and to check the quality and consistency. Eight clinical indicators are evaluated.ResultsThe Register counts 77,628 patients registered by 126 centres. The number of centres has increased over time, as their capacity to collect patients.The percentages of updated patients (with at least one visit in the last 24 months) have increased from 33% (enrolment period 2000-2015) to 60% (enrolment period 2016-2022). In the cohort of patients registered after 2016, there were >= 75% updated patients in 30% of the small centres (33), in 9% of the medium centres (11), and in all the large centres (2).Clinical indicators show significant improvement for the active patients, expanded disability status scale every 6 months or once every 12 months, visits every 6 months, first visit within 1 year and MRI every 12 months.ConclusionsData from disease registers provide guidance for evidence-based health policies and research, so methods and strategies ensuring their quality and reliability are crucial and have several potential applications

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
