Bhushan S, Huang X, Jiang F, Xiao Z. Impact of angiotensin receptor-neprilysin inhibition (ARNI) in improving ejection fraction and left and right ventricular remodeling in heart failure. Curr Probl Cardiol 2024; 49:102464. [PMID: 38369206 DOI: 10.1016/j.cpcardiol.2024.102464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 02/09/2024] [Accepted: 02/15/2024] [Indexed: 02/20/2024]
Abstract
Angiotensin receptor neprilysin inhibitors (ARNI), a new therapeutic class of agents acting on the renin angiotensin aldosterone system (RAAS) and neutral endopeptidase system has been developed in treatment of ventricular remodeling and has attracted considerable attention. The first in class is LCZ696, which is a molecule that combines Valsartan (ARB) and Sacubitril (neprilysin inhibitor) within a single substance. Sacubitril-Valsartan is the first angiotensin receptor enkephalin inhibitors (ARNI), which can block angiotensin II type 1 receptor (AT1R) while inhibiting enkephalin (NEP) and effectively reverse ventricular remodeling in heart failure patients. It has been recommended by the European and American authoritative guidelines on heart failure as Class I for the treatment of chronic heart failure particularly as intensive care medicine. Sacubitril-Valsartan demonstrated significant effects in improving left ventricular performance and remodeling in patients with heart failure with reduced ejection fraction. Sacubitril acts on increased levels of circulating natriuretic peptides by preventing their enzymatic breakdown and Valsartan, which acts to lessen the effects of the RAAS. However, not more research has been done on its effects on the right ventricle remodeling. This review aimed to assess the impact of angiotensin receptor neprilysin inhibitors on left and right ventricular remodeling in heart failure patients.

The combination of rolipram and cilostamide improved the developmental competence of cloned porcine embryos. Sci Rep 2023; 13:5733. [PMID: 37029228 PMCID: PMC10081996 DOI: 10.1038/s41598-023-32677-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 03/31/2023] [Indexed: 04/09/2023] Open
Abstract
In vitro maturation of porcine oocytes is characterized by asynchronous cytoplasmic and nuclear maturation, leading to less competent oocytes supporting embryo development. The purpose of this study was to evaluate the combined effect of rolipram and cilostamide as cyclic Adenine monophosphate (cAMP) modulators to find the maximum cAMP levels that temporarily arrest meiosis. We determined the optimal time to maintain functional gap junction communication during pre-in vitro maturation to be four hours. Oocyte competence was evaluated by the level of glutathione, reactive oxygen species, meiotic progression, and gene expression. We evaluated embryonic developmental competence after parthenogenetic activation and somatic cell nuclear transfer. The combined treatment group showed significantly higher glutathione and lower reactive oxygen species levels and a higher maturation rate than the control and single treatment groups. Cleavage and blastocyst formation rates in parthenogenetic activation and somatic cell nuclear transfer embryos were higher in two-phase in vitro maturation than in the other groups. The relative levels of BMP15and GDF9 expression were increased in two-phase in vitro maturation. Somatic cell nuclear transfer blastocysts from two-phase in vitro maturation oocytes showed a lower level of expression of apoptotic genes than the control, indicating better pre-implantation developmental competence. The combination of rolipram and cilostamide resulted in optimal synchrony of cytoplasmic and nuclear maturation in porcine in vitro matured oocytes and there by enhanced the developmental competence of pre-implantation embryos.

Zare Z, Rezaei N, Mohammadi M. Treatment of mouse cumulus-oocyte complexes with L-carnitine during vitrification and in vitro maturation affects maturation and embryonic developmental rate after parthenogenetic activation. Anat Histol Embryol 2021; 51:44-50. [PMID: 34687237 DOI: 10.1111/ahe.12750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Revised: 09/20/2021] [Accepted: 10/15/2021] [Indexed: 11/29/2022]
Abstract
The technique of oocyte vitrification remains a challenge in most animal species. The present study aimed to evaluate the effects of cumulus cell presence and L-carnitine (LC) treatment during vitrification of selected immature oocytes by brilliant cresyl blue (BCB) staining on maturation and embryonic developmental rate after parthenogenetic activation. Immature oocytes were obtained from C57BL/6 female mice ovaries and stained with BCB. The BCB+ cumulus-oocyte complexes (COCs) were then selected and random parts of COCs were denuded from cumulus cells (denuded oocytes: DOs). COCs and DOs were treated with/out LC (0.6 mg/ml) during vitrification and in vitro maturation (IVM) procedures. A number of non-vitrified COCs were also treated with LC during the IVM process (fresh group). Maturation rate, intracellular glutathione (GSH) contents, and developmental competence of oocytes were also examined. The GSH levels in vitrified DOs+LC and vitrified COCs+LC groups were significantly higher (p < 0.01) than untreated vitrified-warmed COCs and DOs. Maturation rate and blastocyst developmental rate were reduced after the vitrification-warming procedure compared with the fresh group. The vitrified COCs+LC group showed a higher percentage of mature oocytes and the ability to develop to blastocyst stage than the vitrified-warmed DOs group (p < 0.01). These data indicated that the presence of cumulus cells around the competent oocyte and LC treatment during vitrification and IVM procedure could improve parthenogenetic developmental competence of vitrified-warmed oocytes by increasing GSH levels and accelerating oocyte maturation.

Highly successful production of viable mice derived from vitrified germinal vesicle oocytes. PLoS One 2021; 16:e0248050. [PMID: 33705447 PMCID: PMC7951897 DOI: 10.1371/journal.pone.0248050] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Accepted: 02/18/2021] [Indexed: 11/24/2022] Open
Abstract
The vitrification of immature germinal vesicle (GV) oocytes is an important way to preserve genetic resources and female fertility. However, it is well known that cryopreserved GV oocytes have very poor developmental ability and that further improvement in this technique is needed. We previously reported the successful vitrification of matured mouse oocytes with enclosed cumulus cells using the calcium-free vitrification solution supplemented with ethylene glycol (EG) by the minimal volume cooling (MVC) method. In this study, we investigated whether our method is applicable to the vitrification of mouse oocytes at the GV stage (GV oocytes). Following maturation and fertilization in vitro, vitrified GV oocytes showed high survival (94.3 ± 2.0%) and maturation (94.3 ± 2.1%) rates. Although the fertilization and blastocyst rates of vitrified oocytes (fertilization: 46.6 ± 4.9% and blastocyst: 46.6 ± 3.0%) were significantly lower than those of fresh oocytes (fertilization: 73.0 ± 7.1% and blastocyst: 71.6 ± 8.0%) (P < 0.01), there were no differences in the ability to develop to term between fresh oocytes (50.0 ± 8.4%) and vitrified oocytes (37.5 ± 4.6%) (P > 0.05). In conclusion, we here show, for the first time, the efficient production of live mice derived from vitrified GV oocytes.
