Longitudinal assessment of blepharospasm severity in patients with long disease duration.

Introduction: Blepharospasm (BSP) represents one of the most common idiopathic adult-onset dystonia. A few longitudinal observations indicated progression and worsening of BSP severity within 16 years of onset. Information is lacking about the trend of BSP severity in the later stages of the disease.

Does sex influence the natural history of idiopathic adult-onset dystonia?

Background: Several earlier studies showed a female predominance in idiopathic adult-onset dystonia (IAOD) affecting the craniocervical area and a male preponderance in limb dystonia. However, sex-related differences may result from bias inherent to study design. Moreover, information is lacking on whether sex-related differences exist in expressing other dystonia-associated features and dystonia spread.

Discovery and Structure-Activity Relationships of Novel DAF-12 Receptor Modulators.

The nuclear receptor DAF-12 has been recognized as the key molecular player regulating the life cycle of the nematode parasite . DAF-12 ligands permit the receptor to function as an on/off switch modulating infection, making it vulnerable to therapeutic intervention. In this study, we report the design and synthesis of a set of novel dafachronic acid derivatives, which were used to outline the first structure-activity relationship targeting the DAF-12 receptor and to unveil hidden properties shared by the molecular shape of steroidal ligands that are relevant to the receptor binding and modulation.
