Case report: The activity of multi-kinase VEGF inhibitor, Pazopanib, in metastatic undifferentiated round cell sarcomas harboring fusion: clinicopathological series of two cases and literature review.

Soft tissue sarcomas harboring fusion are rare and challenging to treat. Pazopanib, a multi-tyrosine kinase inhibitor, is FDA-approved for advanced soft tissue sarcomas, but predictive biomarkers for its efficacy remain unidentified. We conducted a study on > 240,000 neoplasms submitted to Caris Life Sciences (Phoenix, AZ) to detect rearrangements using whole transcriptome sequencing.

Unusual Variants of Teratoma Involving the Gynecologic Tract.

Teratomas are tumors of germ cell origin, and in the female genital tract are subclassified as immature or mature based on the presence or absence, respectively, of immature elements. Somatic tumors may also develop in association with teratomas, and most commonly include thyroid tumors, carcinoids and carcinomas. We report herein 2 rare forms of gynecologic teratomas: 1 case of immature teratoma of the uterus and 1 case of a benign follicular hamartoma arising in association with mature cystic teratoma of the ovary.

Clinical Outcomes, Health Care Costs and Prognostic Factors for Total Knee Arthroplasty: A Multilevel Analysis of a National Cohort Study Using Administrative Claims Data.

Total knee arthroplasty (TKA) is one of the most frequent orthopaedic surgeries. The purpose of this study was to determine the 30-day postoperative mortality rate, total episode-of-care costs, and prognostic factors associated with these outcomes, for adult patients who underwent TKA in Colombia's contributory health care system. A retrospective cohort study of all adult patients enrolled in Colombia's contributory health system, who underwent TKA between January 1, 2012 and November 30, 2015 was performed.

Using IR and Raman spectra to explain the catalytic activity of the Fe(II)/Fe(III) pair toward the cleavage of peptide bonds.

IR and Raman experiments of formamide (FA) solutions containing variable amounts of Fe(II) and Fe(III) salts were carried out. The νCO vibration is downshifted whereas the νCN mode is upshifted in the presence of the divalent ion. As the trivalent ion is added to the solvent, upshifts of both νCO and νCN vibrations are observed.
