Striatal stimulation enhances cognitive control and evidence processing in rodents and humans.

Brain disorders, in particular mental disorders, might be effectively treated by direct electrical brain stimulation, but clinical progress requires understanding of therapeutic mechanisms. Animal models have not helped, because there are no direct animal models of mental illness. Here, we propose a potential path past this roadblock, by leveraging a common ingredient of most mental disorders: impaired cognitive control.

FGFR2-fusions define a clinically actionable molecular subset of pancreatic cancer.

Genomic alterations in fibroblast growth factor receptor (FGFR) genes are present in a small number of metastatic pancreatic ductal adenocarcinomas (PDAC) and may represent an emerging subgroup of patients likely to benefit from FGFR targeted therapies. Here we present four FGFR2 fusion-positive metastatic PDAC patients who exhibited durable responses or disease control to FGFR kinase inhibitors. Utilizing our custom FGFR focused cell-free DNA assay, FGFR-Dx, we serially monitored variant allele fractions of FGFR2 fusions during FGFR inhibitor treatment and observed dynamic changes correlating with clinical responses.

Evaluation of a Quality Measure for Multiple Sclerosis Care: Disease-Modifying Therapy Initiation at the University of North Carolina's Outpatient Neurology Clinic.

Background: Multiple sclerosis (MS) is a neurological condition leading to significant disability and challenges to quality of life. To slow progression and reduce relapses, it is critical to rapidly initiate disease-modifying therapy (DMT) after diagnosis. Patient demographics may play a role in timely DMT initiation.

Progesterone regulates tissue non-specific alkaline phosphatase (TNSALP) expression and activity in ovine utero-placental tissues.

Background: Tissue non-specific alkaline phosphatase (TNSALP; encoded by the ALPL gene) has a critical role in the postnatal regulation of phosphate homeostasis, yet how TNSALP activity and expression are regulated during pregnancy remain largely unknown. This study tested the hypothesis that progesterone (P4) and/or interferon tau (IFNT) regulate TNSALP activity during pregnancy in sheep.

Metastatic malignant peripheral nerve sheath tumor of the uterus and cervix: Diagnostic Challenges, prognostic determinants and treatment.

•MPNST is an uncommon sarcoma of the nerve sheath that is rarely found in the female reproductive tract.•Preoperative uterine mass imaging should include pelvic MRI and thorough evaluation of imaging by an expert pelvic MRI radiologist.•Metastatic MPNST has a poor prognosis and systemic treatment options lack efficacy.
