Probabilistic Refinement of Focused Ultrasound Thalamotomy Targeting for Parkinson's Disease Tremor.

Background: There remains high variability in clinical outcomes when the same magnetic resonance image-guided focused ultrasound (MRgFUS) thalamotomy target is used for both essential tremor (ET) and tremor-dominant Parkinson's disease (TDPD).

Objective: Our goal is to refine the MRgFUS thalamotomy target for TDPD versus ET.

Methods: We retrospectively performed voxel-wise efficacy and structural connectivity mapping using 3-12-month post-procedure hand tremor scores for a multicenter cohort of 32 TDPD patients and a previously published cohort of 79 ET patients, and 24-hour T1-weighted post-MRgFUS brain images.

Antifungal activity of terpenes isolated from the Brazilian Caatinga: a review.

Terpenoids, also named terpenes or isoprenoids, are a family of natural products found in all living organisms. Many plants produce terpenoids as secondary metabolites, and these make up a large part of essential oils. One of most important characteristic is that the compounds are volatile, have odor and can be used in a variety of applications in different industrial segments and traditional medicine.

Cannabis sativa: A look at protozoa, helminths, insect vectors, and pests.

Active principles extracted from plants, such as essential oils, have been commonly described in the literature as therapeutic targets for numerous pathological conditions. Cannabis sativa, which has an ancient and peculiar history, has been used for various purposes, from recreational to compounds of pharmacotherapeutic and industrial importance, such as pesticides based on this plant. It is a plant that contains approximately 500 described cannabinoid compounds and is the target of in vitro and in vivo studies at different locations.

Evaluation of the complete Sniffin Sticks Test versus its subtests in differentiating Parkinson's disease patients from healthy controls.

Background: Hyposmia is one of the most common, as well as the first nonmotor condition in Parkinson disease (PD). The sniffin sticks test (SST) evaluates three different aspects of olfactory function: threshold (T), discrimination (D), and identification (I). The sum of the scores of these three subtests produce a global score of olfaction, the Threshold-Discrimination-Identification (TDI) score.

Evaluation of ortogonblender software bone movement tools in bimaxillary orthognatic surgeries performed in dolphin software.

The aim of this observational, longitudinal and retrospective study was to evaluate the fidelity of virtual surgical planning (VSP) performed on Dolphin Imaging & Management Solutions® 11.95 software on hard tissues, using the tools of the open-source software OrtogOnBlender - Blender3D. For this, linear, angular and 7-point anatomical measurements of the skeletal profile were used, and the discrepancies between the VSP and the result after bimaxillary orthognathic surgery were calculated.
