The expression of these transcription factors enables a differentiated somatic cell to reverse its phenotype to an embryonic state, generating induced pluripotent stem cells (iPSCs). iPSCs from canine fetal fibroblasts were produced through lentiviral polycistronic human and mouse vectors (hOSKM/mOSKM), aiming to obtain pluripotent stem cells with similar features to embryonic stem cells (ESC) in this animal model. The cell lines obtained in this study were independent of LIF or any other supplemental inhibitors, resistant to enzymatic procedure (TrypLE Express Enzyme), and dependent on bFGF. Clonal lines were obtained from slightly different protocols with maximum reprogramming efficiency of 0.001%. All colonies were positive for alkaline phosphatase, embryoid body formation, and spontaneous differentiation and expressed high levels of endogenous OCT4 and SOX2. Canine iPSCs developed tumors at 120 days post-injection in vivo. Preliminary chromosomal evaluations were performed by FISH hybridization, revealing no chromosomal abnormality. To the best of our knowledge, this report is the first to describe the ability to reprogram canine somatic cells via lentiviral vectors without supplementation and with resistance to enzymatic action, thereby demonstrating the pluripotency of these cell lines.}, journal={Theriogenology}, publisher={Elsevier BV}, author={Gonçalves, N.J.N. and Bressan, F.F. and Roballo, K.C.S. and Meirelles, F.V. and Xavier, P.L.P. and Fukumasu, H. and Williams, C. and Breen, M. and Koh, S. and Sper, R. and et al.}, year={2017}, month={Apr}, pages={75–82} }

Three experiments were conducted. In the first experiment, 13 herbaceous species were grown in a root substrate of three sphagnum peatmoss: one perlite (v/v) with deionized water and a neutral fertilizer (NF) with a PABR of 0 for 78 days to determine species relationships to substrate pH. The decrease in substrate pH ranged from 0.14 to 2.45 units, depending on species. In the second experiment, four of the 13 species from the previous trial representing the range of pH suppression were grown under similar growth conditions as the first experiment for 70 days. Substrate pH was lowered in the range of 0.47 to 2.72 units. In the third experiment, three fertilizers with PABRs of 150 kg·t−1 CaCO3 equivalent alkalinity, 0 neutral, and 193 kg·t−1 CaCO3 equivalent acidity were applied in a factorial design at 100 and 200 mg·L−1 N at each irrigation to kalanchoe (the species with the greatest pH suppression from the previous experiments) for 56 days. When applied at the lower fertilizer rate (100 mg·L−1 N), the PABRs resulted in the final substrate pH levels of 4.68, 5.60, and 6.11 for the acidic fertilizer (AF), NF, and basic fertilizer (BF), respectively. At the high fertilizer rate (200 mg·L−1 N), substrate pH declined continuously to 3.97, 4.03, and 4.92 for the AF, NF, and BF, respectively. Expression of PABR depended on the balance between the abiotic (chemical) effect of the fertilizers vs. the biotic (physiological) effects of the fertilizers on microbes and plants. The PABR was best expressed when the fertilizer supply was just adequate or lower indicating a closer connection to the biotic effect.}, number={12}, journal={HORTSCIENCE}, author={Jeong, Ka Yeon and Nelson, Paul V. and Niedziela, Carl E., Jr. and Dickey, David A.}, year={2016}, month={Dec}, pages={1596–1601} }

Thirteen pregnant pony mares between 18 and 190 d of gestation (mean ± SEM, 101 ± 55) were utilized for the study during two trial periods. In each trial, pentoxifylline (17 mg/kg by mouth every 12h, diluted in syrup) was administered to half of the mares for 3 d, while the other mares were treated with syrup only. Doppler measurements were obtained from the right and left uterine arteries from each mare for 2 d prior to treatment and throughout the treatment period. The mean Resistivity Index (RI), Pulsatility Index (PI), Uterine Artery Diameter (D), and Total Arterial Blood Flow (TABF) from each day were compared over time and between groups. Administration of pentoxifylline did not alter uterine blood flow parameters compared with controls (values for all treatment days combined were RI: 0.517 ± 0.014 vs 0.543 ± 0.016; PI: 0.876 ± 0.048 vs 0.927 ± 0.057; D: 0.388 ± 0.018 vs 0.379 ± 0.023 cm; and TABF: 35.26 ± 7.38 vs 30.73 ± 5.29 mL/min). Uterine blood flow increased over the course of the 5 d study, irrespective of treatment, and was higher in mares of greater gestational age than in early gestational mares (RI: r2 = 0.35; PI: r2 = 0.37; D: r2 = 0.66; and TABF: r2 = 0.67 – P < 0.00001). We concluded that any immediate benefits of pentoxifylline administration in the pregnant mare were not mediated through enhanced uterine artery blood flow.}, number={2}, journal={THERIOGENOLOGY}, author={Bailey, C.
