| 6 | Application of cattle placental stem cells for treating ovarian follicular cyst显示文摘BACKGROUND High humidity and temperature in Taiwan have significant effects on the reproductivity of Holstein cattle,resulting in the occurrence of bovine ovarian follicular cyst(OFC).Because of economic loss from OFC,manual rupture and hormone injection have been advocated for the management of OFC.However,these incomplete treatments increase hormone resistance in cattle.Mesenchymal stem cells(MSCs)derived from placental stem cells(PSCs)demonstrate potential properties for the treatment of several diseases via promoting angiogenesis and immune modulation.AIM To establish the possibility of cattle placental stem cells(CPSCs)as a treatment modality for OFC of cows in Taiwan.METHODS The cows with OFC were divided into three groups:control(BC1 and BC2),hormone(H1 and H2),and CPSC(PS1 and PS2)treatment groups.In the hormone treatment group,the cows were given gonadotrophin-releasing hormone(GnRH)-prostaglandin-GnRH intramuscular injection with or without drainage of follicular fluid.In the CPSC treatment group,CPSCs were isolated from the placenta after labor.With the identification of surface antigen on stem cells,the cows were administered ovarian injection of 1×106 or 6×106 CPSCs with drainage.In all groups,OFC was scanned by ultrasound once a week for a total of seven times.The concentrations of estradiol and progesterone in serum were tested in the same period.The estrus cycle was analyzed by food intake and activity.If estrus was detected,artificial insemination was conducted.Then the cow was monitored by ultrasound for confirmation of pregnancy.RESULTS After 7 d of culture,CPSCs were successfully isolated from placental pieces.CPSCs significantly proliferated every 24 h and had high expression of MSC markers such as cluster of differentiation 44,as determined by flow cytometry.Ultrasound showed lower numbers of OFCs with drainage of follicular fluid.We achieved recovery rates of 0%,50%,50%,75%,75%and 75%in BC1,BC2,H1,H2,PS1,and PS2,respectively.Higher concentrations of progesterone were detected in the CPSC treatment groups.However,both hormone and CPSC treatment groups had no significant difference in the concentration of estradiol.The estrus rate was 0%,100%,25%,75%,75%and 75%in BC1,BC2,H1,H2,PS1,and PS2,respectively.The two fetuses were born in H2 and PS1.In brief,cows with CPSC injection achieved higher recovery,estrus,and inseminated conception rates.CONCLUSION CPSCs have efficacy in treating cows with OFC,and thus,may serve as an alternative treatment for reproductive disorders. | Shao-Yu Peng Tsung-Hsin Wu Tzu-Yi Lin Ling-Yien Hii Kok-Seong Chan Tzu-Yen Fu Shen-Chang Chang Perng-Chih Shen Kang-You Liu Steven W.Shaw | 2020 | World Journal of Stem Cells2020，12，11： | 1 |
| 8 | Banana Xanthomonas wilt dynamics with mixed cultivars in a periodic environment Juliet显示文摘In this paper,we study a deterministic model with non-autonomous system for mixed cultivars to assess the effect of cultivar susceptibility and seasonal variation on banana Xanthomonas wilt(BXW)disease dynamics.A special case of two cultivars classified as highly susceptible for inflorescence infection(ABB)and less susceptible(AAA)cultivar is considered.The basic reproduction number corresponding to the non-autonomous system is derived and numerically computed to determine disease dynamics.Results showed that the disease dies out whenever the periodic basic reproduction number is less than unity and a periodic solution is obtained when it is greater than one.Results further showed that for both cultivars,the basic reproduction number increases with increasing values of the transmission rates and declines exponentially with increasing values of roguing rates.The critical roguing rate of ABB-genome cultivar was higher than that of AAA-genome cultivars.The peaks in disease prevalence indicate the importance of effective implementation of controls during the rainy season.We conclude that highly susceptible cultivars play an important role in the spread of BXW and control measures should be effectively implemented during the rainy season if BXW is to be eradicated. | N.Nakakawa Joseph Y.T.Mugisha Michael W.Shaw Eldad Karamura | 2020 | International Journal of Biomathematics2020，13，1： | 0 |
