Apoptotic Factors, CaNma111 and CaYbh3, Function in Candida albicans Filamentation by Regulating the Hyphal Suppressors, Nrg1 and Tup1.

The morphological switch from the yeast to hyphal form is a key virulence attribute of the opportunistic fungal pathogen, Candida albicans. Our recent report showed that deletion of the newly identified apoptotic factor, CaNma111 or CaYbh3, leads to hyperfilamentation and increased virulence in a mouse infection model. CaNma111 and CaYbh3 are homologs of the pro-apoptotic protease, HtrA2/Omi, and BH3-only protein, respectively.

Magnetic Resonance-Guided High Intensity Focused Ultrasound for Treating Movement Disorders.

Transcranial magnetic resonance-guided focused ultrasound (MRgFUS) surgery has recently gained favor as a novel, noninvasive alternative to conventional neurosurgery. In contrast to traditional ablative interventions, transcranial MRgFUS surgery is entirely imaging-guided and uses continuous temperature measurements at the target and surrounding tissue taken in real-time. Unlike Gamma Knife radiosurgery, MRgFUS surgery can make a lesion immediately and does not use ionizing radiation.

Bilateral thermal capsulotomy with MR-guided focused ultrasound for patients with treatment-refractory obsessive-compulsive disorder: a proof-of-concept study.

Despite optimal pharmacotherapy and cognitive-behavioral treatments, a proportion of patients with obsessive-compulsive disorder (OCD) remain refractory to treatment. Neurosurgical ablative or nondestructive stimulation procedures to treat these refractory patients have been investigated. However, despite the potential benefits of these surgical procedures, patients show significant surgery-related complications.
