Right Care for the Right Patient Each and Every Time.

Purpose: To implement a biometric patient identification system in the field of radiation oncology.

Materials And Methods: A biometric system using palm vein scanning technology has been implemented to ensure the delivery of treatment to the correct patient each and every time. By interfacing a palm vein biometrics system (PVBS) (PatientSecure®, Imprivata, Lexington, Massachusetts) with the radiation oncology patient management system (ROPMS) (ARIA®, Varian Medical Systems, Palo Alto, California) one can integrate patient check-in at the front desk and identify and open the correct treatment record of the patient at the point of care prior to the initiation of the radiation therapy treatment.

High-resolution melt analysis does not reveal mutagenic risk in sexed sperm and in vitro-derived bovine embryos.

The objectives of the present work were to verify whether simultaneous exposure to Hoechst 33342 and UV irradiation during sorting by flow cytometry may induce gene point mutations in bovine sperm and to assess whether the dye incorporated in the sperm may imply a mutagenic effect during the embryonic development. To this aim, high-resolution melt analysis (HRMA) was used to discriminate variations of single nucleotides in sexed vs. non-sexed control samples.

Differential gene expression in cumulus oocyte complexes collected by ovum pick up from repeat breeder and normally fertile Holstein Friesian heifers.

The aim of this study was to establish whether perturbed gene expression during cumulus oocyte development causes repeat breeding in cattle. In this study, a repeat breeder was defined as a normal estrous cycling animal that did not become pregnant after three inseminations despite the absence of clinically detectable reproductive disorders. Transcripts of genes extracted from cumulus oocyte complexes (COC) that were collected from three repeat breeder and three normally fertile Holstein Friesian heifers were compared.

Minimum number of spermatozoa per dose in Mediterranean Italian buffalo (Bubalus bubalis) using sexed frozen semen and conventional artificial insemination.

In buffaloes, AI with sexed semen is not fully optimized, and the procedure has only been performed using the approach currently in use for cattle. The objective of the present work was to compare the pregnancy rates in Mediterranean Italian buffalo cows inseminated with sexed frozen-thawed semen at 2, 4, 6, and 8 million sperm per dose, using the Ovsynch protocol and conventional AI at a fixed time. Fresh ejaculates from three buffalo bulls were processed according to Beltsville sperm sorting technology, and packaged in 0.

Random positional variation among the skull, mandible, and cervical spine with treatment progression during head-and-neck radiotherapy.

Purpose: With 54 degrees of freedom from the skull to mandible to C7, ensuring adequate immobilization for head-and-neck radiotherapy (RT) is complex. We quantify variations in skull, mandible, and cervical spine movement between RT sessions.

Methods And Materials: Twenty-three sequential head-and-neck RT patients underwent serial computed tomography.
