The role of frataxin in fission yeast iron metabolism: Implications for Friedreich’s ataxia

The role of frataxin in fission yeast iron metabolism: Implications for Friedreich’s ataxia. Yu Wang, Yiwei Wang, S. Marcus, L.S. Busenlehner; Biochimica et Biophysica Acta (BBA) - General Subjects, Available online 3 July 2014, ISSN 0304-4165, http://dx.doi.org/10.1016/j.bbagen.2014.06.017

This paper provide evidence that suggests dysregulated Fe-S cluster biogenesis is a primary effect of both frataxin overexpression and deficiency as in Friedreich’s ataxia, it also suggests that therapies to increase transcription and translation of endogenous frataxin or to replace exogenous frataxin via gene therapy, must tightly control protein expression since high levels of frataxin are detrimental to the cell in a manner similar to its deficiency.

Joint preserving surgery versus arthrodesis in operative treatment of patients with neuromuscular polyneuropathy: questionnaire assessment.

Joint preserving surgery versus arthrodesis in operative treatment of patients with neuromuscular polyneuropathy: questionnaire assessment. Marek Napiontek,
Krzysztof Pietrzak; European Journal of Orthopaedic Surgery & Traumatology, June 2014, DOI 10.1007/s00590-014-1498-9

Keywords: Foot, Paralytic deformity, Charcot–Marie–Tooth disease, Friedreich ataxia, Neuromuscular polyneuropathy

The results show that none of the surgical techniques used for correction of foot deformities in motor-sensory polyneuropathies seems to be preferable.

Lanzaderas y terapia génica contra la ataxia de Friedreich

Lanzaderas y terapia génica contra la ataxia de Friedreich .“excelenciencia.org”. 19/06/2014

"Si se cumplen las previsiones, apunta Teixidó, antes de las próximas navidades la tecnología resultante de esta unión debería verificarse en modelos animales e iniciar el camino de investigación preclínica que finalmente desemboque en un eventual ensayo clínico."

La unión de los dos centros de investigación y la capacidad de la plataforma permitieron desarrollar un sólido proyecto que atrajo la atención de la estadounidense The Friedreich's Ataxia Research Alliance (FARA), http://www.curefa.org/ de gran potencia organizativa y, sobre todo, económica.



Corneal Sensitivity and Tear Function in Neurodegenerative Diseases.

Corneal Sensitivity and Tear Function in Neurodegenerative Diseases. Ornek N, Dağ E, Ornek K; Current eye Research [2014:1-6]

FA patients did not show any abnormalities in either outcome measures, Corneal sensitivity measured using a Cochet-Bonnet esthesiometer and Tear function tests which included tear break-up time (TBUT) and Schirmer's. This may be attributed to, unlike other Neurodegenerative Diseases, lack of autonomic disturbances in FA patients
