Electromyographic measures of asymmetric muscle control of swallowing in Parkinson's disease.

Introduction: During the early stages, Parkinson's disease (PD) is well recognized as an asymmetric disease with unilateral onset of resting tremor with varying degrees of rigidity, and bradykinesia. However, it remains unknown if other impairments, such as swallowing impairment (i.e.

The Feasibility of Group Therapeutic Singing Telehealth for Persons with Parkinson's Disease in Rural Iowa.

Group therapeutic singing (GTS) may be an effective treatment for voice and respiratory impairments in persons with Parkinson's disease (PD). However, it remains unknown if GTS can be effectively delivered through telemedicine. Participants with PD from rural areas were recruited to complete a prerecorded GTS program, once a week for 8 weeks.

Glial cell responses in a murine multifactorial perinatal brain injury model.

The impact of traumatic brain injury during the perinatal period, which coincides with glial cell (astrocyte and oligodendrocyte) maturation was assessed to determine whether a second insult, e.g., increased inflammation due to remote bacterial exposure, exacerbates the initial injury's effects, possibly eliciting longer-term brain damage.

Development and validation of a diagnostic test for Ridge allele copy number in Rhodesian Ridgeback dogs.

Background: The breed-defining dorsal ridge in Rhodesian Ridgeback dogs is the result of a 133,000 base pair duplication on chromosome 18. Because this trait is dominant, heterozygous dogs cannot be discriminated from those with two copies of the Ridge allele.

Results: A quantitative PCR test was developed and dogs of known genotype were used as test subjects.
