A mathematical model appraising the effect of metabolic control on joint mobility in young diabetic patients: a preliminary study
Get PDFObjective. The impairment of glycemic control can induce limited joint mobility even in young type 1 diabetic (T1DM) patients. The aims of this study were to verify the presence of ankle joint mobility (AJM) deficits in young T1DM subjects and define a mathematical model of diabetes mellitus long-term effects on AJM. Methods. AJM was evaluated using an inclinometer in 37 patients and 53 healthy, sex- BMI- and age-matched controls. To set up the mathematical model, we assumed that reduced metabolic control affects AJM according to a lognormal function: requiring some time for development of a reduction of joint mobility, which then persists for a long period, before fading out over time (if glycemic control has been recovered). A non-linear optimization determined the model parameters to achieve the best fit for a series of patients. Results. Both plantar and dorsiflexion AJM was significantly lower in diabetic subjects than in controls (plantarflexion: 28.5°±7.5 vs 35.2°±6.5; dorsiflexion: 93.9°±16.0 vs 104.7±12.8; p<0.01). The defined model approximates the experimental data with good accuracy; after optimization, the lognormal curve obtained is in line with empirical estimates: lack of glycemic control needs to persist for at least a few months before producing a significant effect, that lasts up until one year. The fitting procedure indicated the optimal solution is p = (37; 30; 3:5; 6:7; 137); thus, the optimal _im(t) corresponds to the curve reported. Conclusion. AJM was significantly reduced in young T1DM patients. The mathematical model represents the experimental data accurately
A study of incidence of trifurcation of left coronary artery in adult human hearts
Get PDFThe aim of our present study is to determine the incidence of trifurcation of left coronary artery in 75 adult human hearts of Hyderabad, Karnataka region. The incidence of trifurcation of left coronary artery in our present study is 14.5%. Since the left main coronary artery supplies the majority of the left ventricle of the heart and as the diseases of left coronary artery are most common, the management of diseases involving the left coronary artery trifurcation is very challenging. Hence this study done involving trifurcation of left coronary artery will be helpful to the physicians, vascular surgeons and cardiac surgeons of this region
Anatomy of the glenohumeral ligaments
Get PDFFor many years, there has been controversy regarding the presence of the glenohumeral ligaments; the aim of the present study was to evaluate the detailed anatomy of these ligaments. 140 shoulders were dissected and examined. The detailed anatomy of glenohumeral ligaments was recorded. Data were doubled-entered into the Statistical Package for Social Sciences version 21. Kruskal-Wallis and one way analysis for variance on ranks tests were used: statistical significance was set at p<0.05. The superior glenohumeral ligament was present in all specimens originating from the glenoid labrum anterosuperior aspect, inserting into the lesser tubercle (mean thickness 5.06 mm). The middle glenohumeral ligament was present in 98.57% of specimens arising from the glenoid labrum anterior aspect, inserting into the lesser tubercle (mean thickness 5.97 mm). The inferior glenohumeral ligament anterior band was present in all specimens arising from the glenoid labrum anteroinferior aspect, inserting into the humeral neck anteroinferior aspect (mean thickness 4.41 mm). The inferior glenohumeral ligament posterior band was observed in 79.28% of specimens arising from the posteroinferior aspect of the glenoid labrum, inserting into the humeral neck posteroinferior aspect: its mean thickness was 3.45 mm. this study concludes that the superior glenohumeral ligament was observed in all specimens. The middle glenohumeral ligament was seen in 98.57%. An anterior band of the inferior glenohumeral ligament was present in all specimens, while a posterior band was present in 79.28%. A tuberculohumeral ligament was seen in 54.83% of specimens. The present observations should encourage evaluation of the function of this ligament

Thermal tolerance for two cohorts of a native and an invasive freshwater turtle species
No full textThe ability to tolerate environmental stress may determine invasion success of alien species. Comparative data on physiological thermal tolerance between native and invasive vertebrates are quite limited. Here, we assessed the difference in thermal tolerance between a native (Mauremys reevesii) and an invasive (Trachemys scripta elegans) freshwater turtle species. We incubated eggs of M. reevesii and T. scripta elegans from different cohorts at 29 °C, and measured the critical thermal minimum (CTMin) and maximum (CTMax) of hatchlings. Our results preliminarily showed that the hatchlings of T. scripta elegans had a greater high-temperature tolerance and wider tolerance range than the hatchlings of M. reevesii; in the two-cohort system, individuals from the high-latitude cohort seemed to have greater low-temperature tolerance but similar high-temperature tolerance compared with those from the low-latitude cohort. Relatively greater thermal tolerance ability for T. scripta elegans might reflect its environmental adaptability to thermal stress
L’Armenia moderna: rinascita nazionale e risorgimento mancato
Get PDFFrom the beginning of the 18th century up to the 1915 genocide, Armenian culture underwent a complex, intensive modernization process of a very ancient identity, strongly underpinned by Christianity. After centuries under Islamic domination, this process developed in the shape of a well-organized convergence with Europe as a primarily cultural, but also political model. “Rebirth” (veracnund) and “Awakening” (zart’onk’) are the traditional keywords in a modernization process begun in the 18th century by the Christian humanism of the Mekhitarist Catholic Monastic Order in Venice and the “eccentric” enlightenment of the Indian colonies, continuing in the nineteenth and early 20th centuries by means of wide-ranging polycentric activity, which led to significant progress in the cultural field. However, this process could not evolve politically, mostly owing to an international situation that was opposed to Armenian national aspirations. Instead of a “Risorgimento” the Armenian people, during the 20th century, experienced the tragedy of genocide and the suffering of a diaspora, especially in the earlier stages. This negative situation was only partially softened by the setting up of a small independent republic in 1918, initially under a soviet type regime and now in a state of precarious independence
From High Hopes of the Celtic Twilight to Last Hurrahs in Inter-war Warsaw: The Plays of Casimir Dunin-Markievicz
Get PDFRecent reassessments have done much to show that Casimir Markievicz’s cultural activism in Ireland made unique contributions to its renascent cultural nationalism: his portraiture recorded key moments and personages of the age; whereas his role as a dramatist and theatrical impresario in thrall to Shaw, theatrical naturalism and social engagement represented a supplementation of the Celtic Literary Revival. As a further contribution to what is a growing awareness of the importance of Markievicz as a historical, artistic and literary figure, this article will seek to show that, following the breakdown of his marriage and his return to Poland in 1913, Markievicz would also play a meaningful if short-lived role in the emerging modernity of Warsaw’s post-war theatrical world. It will also look to assess why his career foundered, with consequences for his own literary legacy here in Poland
La nascita di un’industria ospitale europea nel XVIII secolo: locande, stazioni di posta, grandi alberghi e città turistiche
Get PDFDuring the 18th century there was in Europe a sort of ‘internationalization’ of the forms of paid accommodation buildings in terms of features and services offered, following the exponential growth of the number of travelers, especially aristocrats, on the wave of the phenomenon of the Grand Tour. This article analyzes the hospitality forms in the Old Continent, demonstrating how they are closely linked to an evolution of the historical, economic and cultural nature of society that took place during the eighteenth century
