Abstract
Embryonal diapause is a characteristic feature of about 130 mammalian species. However, very few studies have addressed cryopreservation of diapausing embryos. This work is aimed to apply program freezing to blastocysts obtained from CD1 mice, which were at diapause state after ovariectomy and the subsequent hormonal therapy. Blastocysts collected from non-operated mice of the same strain served as controls. Some diapausing as well as non-diapausing frozen-thawed blastocysts demonstrated blastocoel re-expansion after 24 h of in vitro culture (IVC) indicating their viability after cryopreservation. Raman spectroscopy assessment of phenylalanine accumulation revealed that the fraction of new synthesized proteins was lower for non-frozen as well as for frozen-thawed diapausing blastocysts compared to non-diapausing ones. Although protein metabolism was reduced in diapausing embryos, most of the protein synthesis remained active. Cell number increased after 24 h of IVC in non-frozen as well as in the frozen-thawed blastocysts of the control but not of the diapause group. However, cell numbers were increased in frozen-thawed diapausing blastocysts after 47 h of IVC in a medium supplemented with putrescine. This indicates viability of frozen-thawed diapausing embryos after cryopreservation. Besides, protein metabolism was not affected by cryopreservation in diapausing and non-diapausing murine embryos indicating their viability. Our results demonstrated the possibility of successful cryopreservation of diapausing murine embryos.

Abstract
One of the approaches to improve cryotolerance in lipid-rich embryos is to modify their lipidome in vitro. This work is aimed to study the effects of forskolin exposure on the in vitro embryo development of the domestic cat and to evaluate how the change in lipid content affects the cryopreservation results. In vitro-derived embryos were cultured with 10 μM forskolin from the 2-cell stage for 24 h or 96/168 h to the morula/blastocyst stage. Some of the embryos treated with forskolin for 24 h were cryopreserved with slow freezing, the other ones were used to characterize their developmental rates and the amount of intracellular lipids. The in vitro exposure to forskolin had a positive effect on the embryo development, as more embryos developed to the morula stage in the forskolin-treated group (92.9%) compared to the controls (64.7%) after 120 h of in vitro culture (IVC). Nile Red staining revealed a reduced amount of intracellular lipids in the forskolin-treated embryos. The percentage of embryos developed to the morula stage was lower in the frozen-thawed embryos not treated with forskolin (54.5%), but not in the frozen-thawed forskolin-treated group (63.6%) as compared to non-frozen controls (80.8%). Thus, the exposure of embryos to forskolin in vitro reduced the level of intracellular lipids and affected embryo development before and after cryopreservation.

Abstract
Embryo production is a routine procedure in several species. However, in felids, the effectiveness of this approach is far behind that in the majority of laboratory species. The development of a suitable environment starts with the proper composition of culture media. Therefore, for the improvement of assisted reproduction techniques and their outcome in cats, this is an urgent task. As the addition of insulin-like growth factors (IGF-I, IGF-II) or granulocyte-macrophage colony-stimulating factor (GM-CSF) was beneficial in other mammalian species, this study aims to check whether these components, combined with other factors (such as type of fertilisation or type of culture) can provide a benefit in the felid culture system in current use. Thus, these supplements, in different concentrations and combinations, were merged with the use of two fertilisation techniques and randomly assigned to single or group culturing. The results showed that the addition of IGF-I and/or GM-CSF produced an increase in morula and blastocyst rate in a single culture system. In particular, the supplementation with 20 ng/mL of IGF-I incremented the maturation rate by 10% and significantly increased the morula and blastocyst rates in single culturing. This result is especially remarkable for wild felids, where only a few oocytes and/or embryos are available.

Abstract
The study investigates how surgery during pregnancy, i.e., sham operation associated with embryo transfer, affects hypertensive phenotype in ISIAH rats genetically predisposed to hypertension. ISIAH rats born after maternal surgery at fourth day of pregnancy were compared with naturally conceived controls. Surgery during pregnancy in ISIAH rats caused acceleration of neurodevelopment in young offspring, as well as aggravating hypertension, suppressing exploratory activity, reducing hippocampal BDNF expression, and compensatory increasing of hippocampal neuronal density in adult ISIAH offspring. Maternal surgery during early pregnancy caused alterations in offspring phenotype in hypertensive ISIAH rat model.

Abstract
The Far-Eastern wildcat (Prionailurus bengalensis euptilurus) is a rare and poorly investigated nondomestic felid species. An attempt of freezing and cryopreserving Far-Eastern wildcat spermatozoa in CaniPlus Freeze (CPF) medium is reported. Sperm was collected by electroejaculation from five adult Far-Eastern wildcat captive-born males. Epididymal spermatozoa from five adult randomly bred domestic cat males were used as a reference. The viability of frozen-thawed spermatozoa evaluated by double staining with SYBR Green I and PI followed by the subsequent confocal laser scanning microscopy (CLSM) was 38.2% ± 3.0% for the domestic cat and 38.0% ± 10.2% for the Far-Eastern wildcat. The motility of frozen-thawed spermatozoa was 30.8% ± 9.8% for the domestic cat and 33.7% ± 15.1% for the Far-Eastern wildcat. Sperm morphology was assessed by light microscopy. The total percentage of normal spermatozoa after freezing and thawing was 51.9 ± 5.9 for the domestic cat and 55.0% ± 6.4% for the Far-Eastern wildcat. Defects of flagella were the most frequently observed abnormalities in both species (32.2% ± 4.8% and 30.8% ± 4.4% of all reported anomalies for the domestic cat and Far-Eastern wildcat, respectively). Domestic cat epididymal and Far-Eastern ejaculatory spermatozoa fertilized in vitro-matured oocytes of the domestic cat (30.0% ± 5.5% and 35.5% ± 15.0%, respectively). Taken together, these results suggest that the freezing of Far-Eastern wildcat spermatozoa with CPF medium is a suitable method for Felidae cryopreservation.
