Effects of plantar fascia stiffness on the internal mechanics of idiopathic pes cavus by finite element analysis: implications for metatarsalgia.

Metatarsalgia occurring in individuals with pes cavus is typically associated with abnormal loading patterns in the forefoot resulting from structural alterations. Simultaneously, the frequent overstress of the plantar fascia (PF) caused by the persistence of this foot deformity may further exacerbate the chronic pain induced by metatarsal overload. We aimed to investigate and quantify the effects of PF stiffness on the internal biomechanics of pes cavus using a computational modelling approach.

Facile Incorporation of Pd(PPh3)2Hal Substituents into Polymethines, Merocyanines, and Perylene Diimides as a Means of Suppressing Intermolecular Interactions.

Compounds with polarizable π systems that are susceptible to attack with nucleophiles at C-Hal (Hal = Cl, Br) bonds react with Pd(PPh3)4 to yield net oxidative addition. X-ray structures show that the resulting Pd(PPh3)2Hal groups greatly reduce intermolecular π-π interactions. The Pd-functionalized dyes generally exhibit solution-like absorption spectra in films, whereas their Hal analogues exhibit features attributable to aggregation.

[Short and long term prognosis of patients with myocardial infarction. Hungarian Myocardial Infarction Registry].

Introduction: Mortality data of patients with acute myocardial infarction are incomplete in Hungary.

Aim: The aim of the authors was to analyse the data of 8582 myocardial infarction patients (4981 with ST-elevation myocardial infarction) registered in the Hungarian Myocardial Infarction Register in order to define the hospital, 30-day, and 1-year mortality. To evaluate the prehospital mortality of myocardial infarction, all myocardial infarction and sudden death were registered in five districts of Budapest.

[Myocardial Infarction Registry--2010. Experience and first results in Hungary].

Authors present the methodology and first data of Hungarian Myocardial Infarction Register Pilot Study started 1st of January, 2010. The aim of the study is to collect epidemiological data on myocardial infarction, to examine the natural history of the disease and to investigate the main characteristics on patient care in the pilot area. The program is using standardized diagnostic criteria and predefined electronic data record forms (eCRF).
