Oral Lesions in Captive Nondomestic Felids With a Focus on Odontogenic Lesions.

Odontogenic lesions are well described in domestic cats, but published literature describing these lesions in nondomestic felids is limited. This study reports oral lesions in 109 captive, non-domestic felids. Ten cases of odontogenic lesions were diagnosed, including 9 with fibromatous epulis of periodontal ligament origin (FEPLO) and one odontogenic cyst in a cougar.

Vitamin D levels do not affect IVF outcomes following the transfer of euploid blastocysts.

Objective: We sought to characterize the relationship between serum 25-hydroxy vitamin D (25-OH D) levels and implantation and clinical pregnancy rates in women who undergo a euploid blastocyst embryo transfer.

Study Design: This retrospective cohort study, conducted in an academic setting, included 529 cycles in which comprehensive chromosome screening was performed as part of routine infertility care with an autologous transfer of 1 or 2 euploid blastocysts. After excluding repeat cycles there were 517 unique cycles representing 517 women for evaluation.

Selecting the optimal time to perform biopsy for preimplantation genetic testing.

A consistent requirement for all preimplantation genetic testing is the need to obtain DNA from the oocyte or embryo. Currently this sample is attained through biopsy of one or both polar bodies, blastomere biopsy at the cleavage stage, or trophectoderm biopsy after blastulation. Selecting the optimal time for biopsy requires careful consideration.

Blastocyst biopsy with comprehensive chromosome screening and fresh embryo transfer significantly increases in vitro fertilization implantation and delivery rates: a randomized controlled trial.

Objective: To determine whether blastocyst biopsy and rapid quantitative real-time polymerase chain reaction (qPCR)-based comprehensive chromosome screening (CCS) improves in vitro fertilization (IVF) implantation and delivery rates.

Design: Randomized controlled trial.

Setting: Academic reproductive medicine center.
