“…The result is very similar to the 341 ± 1.6 days gestation length (range of 307–360 days) reported for mule pregnancy by [ 5 ], with 315–369 days reported by [ 18 ], and with 342.3 ± 10.8 days reported by [ 19 ]. When pregnancy length was compared to the pregnancy length observed (author's unpublished data) in Half blood draft (339.9 ± 9.18 days) and Italian draft (339.3 ± 11.68 days) mares, the results showed superimposable findings, while it resulted very different when compared to Martina Franca donkey pregnancy length of 333–395 days [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ].…”

Mules (Equus mulus) are interspecific hybrids derived from crossing horse (Equus caballus) mares with jackasses (Equus asinus). In Italy, the production of mules is very important for the special environmental areas, where they are used as working animals, instead of the forbidden agricultural machines. Although many horse mares carry mule pregnancy successfully at term, low fertility of mares used for producing mules was reported, but limited data about reproductive efficiency in mares carrying mule pregnancy, especially when age and reproductive status are concerned, are available. Therefore, the present study aimed to assess the effect of age and of reproductive status on some reproductive indices of horse mares carrying mule pregnancy, in the final purpose to better clarify factors affecting reproductive performances in the valuable production of mules as working animals under special environmental areas in Italy. The study, performed on 96 draft mares inseminated with Martina Franca donkey semen, showed a satisfactory 89.6% 14 days PO pregnancy rate, lower pregnancy losses (19.8%) than those previously reported for mule pregnancies, leading to satisfactory foaling rates (71.9%), similar to those reported for intraspecific horse pregnancies. A clear, significant detrimental effect of mare's age on pregnancy losses, foaling rate, and on number of estrous cycles needed to achieve pregnancy, was found. Reproductive status also affected the reproductive indices, with significantly higher pregnancy losses and lower foaling rate in barren mares, reopening the question about the possible lower reproduction efficiency in horse mares carrying mule pregnancy. The present study results, although mostly descriptive, add useful information about some factors affecting reproductive performances in the valuable production of mules as working animals under special environmental areas in Italy.

“…Both endometrial glandular epithelial cells and luminal epithelial cells proliferated significantly at 7 d after treatment of KGF solution or KGF-HP hydrogel. Promotion of cells proliferation may be associated with a restorative microenvironment by decreasing inflammatory and immune responses (Gargett et al., 2008 ; Zhang et al., 2016 ), because it was reported that KGF decreased expression of TGF-β, a abundantly expressed inflammatory factor in the endometrium after injury of uterus (Carluccio et al., 2016 ). Angiogenesis, the growth of new capillaries from preexisting blood vessels, is essential to support the nutritional demands of tissues that are expanding or being repaired (Gillis et al., 1999 ).…”

Endometrial injury usually results in intrauterine adhesion (IUA), which is an important cause of infertility and recurrent miscarriage in reproductive women. There is still lack of an effective therapeutic strategy to prevent occurrence of IUA. Keratinocyte growth factor (KGF) is a potent repair factor for epithelial tissues. Here, a temperature-sensitive heparin-modified poloxamer (HP) hydrogel with affinity to KGF (KGF-HP) was used as a support matrix to prevent IUA and deliver KGF. The rheology of KGF-HP hydrogel was carefully characterized. The cold KGF-HP solution was rapidly transited to hydrogel with suitable storage modulus (G') and loss modulus (G″) for the applications of uterus cavity at temperature of 33 °C. In vitro release demonstrated that KGF was released from HP hydrogels in sustained release manner for a long time. In vivo bioluminescence imaging showed that KGF-HP hydrogel was able to prolong the retention of the encapsulated KGF in injured uterus of rat model. Moreover, the morphology and function of the injured uterus were significantly recovered after administration of KGF-HP hydrogel, which were evaluated by two-dimensional ultrasound imaging and receptive fertility. Not only proliferation of endometrial glandular epithelial cells and luminal epithelial cells but also angiogenesis of injured uterus were observed by Ki67 and CD31 staining after 7 d of treatment with KGF-HP hydrogel. Finally, a close relatively relationship between autophagy and proliferation of endometrial epithelial cells (EEC) and angiogenesis was firstly confirmed by detecting expression of LC3-II and P62 after KGF treatment. Overall, KGF-HP may be used as a promising candidate for IUA treatment.

“…Assessment of the caudal placental pole (e.g., edema, intracervical fluid accumulation and combined thickness of uterus and placenta {CTUP}) has been used to assess equine pregnancy for signs of ascending placentitis 117 (Figure 20). In the healthy pregnancy, the asinine CTUP seems to grow linearly from the from the sixth month of pregnancy until foaling, with a substantial increase from the ninth to the 12th month of pregnancy 118 . The reported CTUP for normal jennies varied in average 8 mm from 6months of gestation to 12.6 mm by 12 months of gestation 118 (Table 11) Currently, parameters for assessment of high-risk donkey pregnancies are nonexistent.…”
