Abstract:

Blighted ovum atau kehamilan anembrionik merupakan keadaan dimana seorang wanita hamil namun tidak terdapat janin didalam kandungannya, dikarenakan ovum yang dibuahi tidak berkembang. Hingga saat ini penyebab kejadian blighted ovum belum dapat dideteksi karena gejala yang tidak spesifik. Umumnya kejadian blighted ovum terjadi pada trimester I dan memungkinkan untuk terulang kembali pada kehamilan selanjutnya. Tujuan penelitian ini untuk mengetahui gambaran kejadian blighted ovum. Metode penelitian yang digunakan adalah Literature Review yang didapatkan dari 3 database yaitu PubMed, ResearchGate dan Google Scholar dengan kriteria inklusi jurnal terakreditasi Sinta dan Scopus. Hasil penelitian dari 5 jurnal yang telah diidentifikasi melalui proses literature review didapatkan karakteristik ibu hamil berdasarkan usia, paritas, imunologis, dan kelainan genetik ada pada ibu hamil dengan blighted ovum. Ibu hamil yang mengalami blighted ovum memiliki karakteristik usia >40 tahun dengan paritas multigravida dan grandemultigravida serta kelainan genetik.

Abstract:

AbstractNormal men after stepping into the adolescent phase, they must produce sperm. Likewise, normal women after reaching the adolescent phase, they must produce ovum. However, there are still many men and women who have produced sperm or ovum and do not know about the hormones that affect on producing sperm or ovum. In males, the hypothalamus secretes releasing factors and stimulates the anterior pituitary gland to produce follicle stimulating hormone (FSH) and interstitial cell stimulating hormone (ICSH). The combination of FSH and ICSH will stimulate the testes to produce the hormone testosterone. The hormone testosterone is responsible for sperm production, penis growth, facial hair, and widening of the shoulders. In women, the hypothalamus secretes releasing factors and stimulates the anterior pituitary gland to produce follicle stimulating hormone (FSH) and luteinizing hormone (LH). FSH stimulates young follicles until they become mature follicles. Mature follicles due to the influence of luteinizing hormone will rupture, so that the ovum is released from the follicle. Follicles that no longer contain ovum will turn into a corpus luteum. The corpus luteum then produces the hormones progesterone and estrogen to keep the corpus luteum from being damaged.Keywords: Hormones, sperm formation, and ovum formation.

Abstract:

Ovum Pick-up (OPU) associated with IVF has become advancement in ruminant reproduction. Transvaginal OPU guided by ultrasound is a non- invasive technique for cumulating oocytes from Graafian and antral follicles from live donor animals especially from cattle. Laparoscopic OPU in combination with in vitro embryo production increases the possibility of obtaining viable offspring in small ruminants. OPU does not impede with the usual reproduction and production performance of the donor animals and can be apply in various physiological states and circumstances of animals like different ages and reproductive disorders. The persistent collection of oocytes through OPU techniques concedes us to acquire the highest possible progeny of animals with merit genetic value, genetic improvement and advancement in animal selection. Here, we are presenting an overview of OPU from ruminants with factors affecting their outcome.

Abstract:

According to data from the World Health Organization (WHO), the percentage of possible abortion is quite high, around 15-40%. In Indonesia, it is estimated that there are 500,000-750,000 abortions. Blighted ovum is a state of the product of conception that does not contain a fetus. It is estimated that worldwide Blighted ovum is 60% of the causes of miscarriage cases, in ASEAN (association of Southeast Asian Nations) it reaches 51%, in Indonesia it is found 37% of every 100 pregnancies, in Yogyakarta Province it reaches 30% of 100 pregnancies and in Sleman Regency. as much as 43.39% (WHO, 2015). The incidence rate at PKU Muhammadiyah Gamping shows an increase in the Blighted ovum rate during the last 3 years in 2016 as much as 6.02%, in 2017 it increased by 6.05%, and in 2018 it increased by 6.06% (Kemenkes RI, 2018). Mothers who experience abortions due to blighted ovum have characteristics including age, parity, nutrition and gestational spacing, in addition, age, parity, nutrition and gestational spacing are also factors that cause blighted ovum. Objective: To identify the factors that influence the incidence of blighted ovum pregnancy. Research Methodology: This type of research is analytical observational with a cross-sectional approach. The location of this research is PKU Muhammadiyah Gamping Yogyakarta with a sample of 30 respondents and the sampling technique is Simple Random Sampling. The data analysis technique used in this research is chi square. Research Results: Factors related to the incidence of blighted ovum pregnancy are parity factors as indicated by a p-value of 0.004 where the p-value is smaller than the significance value with an error rate of 5% (0.05). This shows that there is a relationship between the parity variable and the incidence of blighted ovum pregnancy. For the nutrition variable, the p-value is 0.151 where the p-value is greater than the significance value with an error rate of 5% (0.05). This shows that there is no relationship between nutritional variables and the incidence of blighted ovum pregnancy.

Abstract:

Polyspermy is a major puzzle in reproductive biology. In some taxa, multiple sperm enter the ovum as part of the normal fertilization process, whereas in others, penetration of the ovum by more than one sperm is lethal. In birds, several sperm typically enter the germinal disc, yet only one fuses with the female pronucleus. It is unclear whether supernumerary sperm play an essential role in the avian fertilization process and, if they do, how females regulate the progression of sperm through the oviduct to ensure an appropriate number reach the ovum. Here, we show that when very few sperm penetrate the avian ovum, embryos are unlikely to survive beyond the earliest stages of development. We also show that when the number of inseminated sperm is limited, a greater proportion than expected reach and penetrate the ovum, indicating that females compensate for low sperm numbers in the oviduct. Our results suggest a functional role for supernumerary sperm in the processes of fertilization and early embryogenesis, providing an exciting expansion of our understanding of sperm function in birds.

Abstract:

Background: This study was performed to determine the level of serum C-reactive protein (CRP) in day of ovum pickup and embryo transfer as a predictor for success in patients undergoing In-Vitro Fertilization (IVF) and Intracytoplasmic Sperm injection (ICSI).Methods: This study was a cross sectional study (prospective) that was conducted in assisted reproduction unit in Al-Azhar University Hospital on 50 infertile patients who were candidate for IVF/ICSI, using standard long protocol, blood was drawn two times during cycle, in the day of ovum pick up and the day of embryo transfer.Results: In (70.6 %) the serum of CRP level was higher in day of embryo transfer than day of ovum pick up. The ratio of CRP level in the day of embryo transfer to the day of ovum pick up was heigher (1.54) in patients who became pregnant after ICSI, patients with less than this ratio have not been pregnant.Conclusions: Controlled ovarian hyper stimulation and puncture of ovaries can potentiate systemic stimulation so increasing serum CRP level in day of embryo transfer rather than day of ovum pick up can predict success in patients undergoing IVF/ICSI.

Klasifikasi menggunakan Naïve Bayes berbasis Particle Swarm Optimization (PSO) yang hanya membutuhkan data training yang kecil untuk menentukan estimasi parameter yang diperlukan dalam proses pengklasifikasian dan penggunaan Particle Swarm Optimization dapat meningkatkan nilai akurasi serta memecahkan masalah optimasi. Dengan proses pemilihan data variable dan data attribute untuk membuat kuisioner sebagai metode pengambilan data. Hasil klasifikasi blighted ovum pada wanita hamil menggunakan algoritma Naïve Bayes dengan framework Rapid Miner mendapatkan nilai akurasi sebesar 71,56% dengan Area Under Curve (AUC) 0,674 termasuk dalam kategori klasifikasi yang baik. Setelah menggunakan optimasi PSO nilai akurasi naik menjadi 79,82% dengan Area Under Curve 0,764 termasuk kategori klasifikasi yang baik. Naïve bayes merupakan metode yang cocok untuk klasifikasi, dan PSO bisa membuat nilai akurasi dan AUC lebih baik lagi.

Abstract:

In vitro embryo production (IVP) is an important tool to enhance genetic gain in cattle. However, oocyte quality is a limiting factor for the success of IVP programs in high-producing donors. A series of studies using protocols for follicular wave synchronization and superstimulation before ovum pickup were performed to improve the efficiency of ovum pickup and in vitro production in dairy cattle. The first study evaluated superstimulation with FSH (Folltropin-V®) before ovum pickup in lactating (n = 15) and non-lactating (n = 15) Holstein donors in a crossover design. Cows underwent synchronization of follicle wave emergence (FWE) and at the expected time of FWE, the FSH group received a total dosage of 200 mg of FSH in 4 decreasing doses 12 h apart; controls received no FSH, and ovum pickup was conducted 72 h after the expected FWE in all cows. The FSH-treated cows had a higher (P < 0.01) percentage of medium-sized follicles (6 to 10 mm) at the time of ovum pickup (55.1%) than control cows (20.8%) as well as lower cumulus‐oocyte complexes (COC) recovery rates (60.0 v. 69.8%, respectively; P = 0.002). However, FSH-treated cows had a higher blastocyst production rate (34.5 v. 19.8%; P < 0.01) and more transferable embryos per ovum pickup session (3.0 ± 0.5 v. 1.8 ± 0.4; P = 0.02). Subsequent trials evaluated plasma FSH profiles in 23 heifers and in vitro production following ovum pickup in 90 non-lactating Holstein donors superstimulated with a single IM injection of FSH in 0.5% hyaluronan (HA; MAP-5®, 50 mg). Controls received no treatment, while the F200 group received 200 mg of FSH in 4 decreasing doses 12 h apart. The F200HA and F300HA groups received 200 or 300 mg of FSH in 5 or 7.5 mL, respectively, of 0.5% HA by a single IM injection. Circulating FSH area under curve (AUC) in FSH-treated animals was greater than in the control group (P = 0.02). Although the AUC for F200 group did not differ from HA groups (P = 0.56), the total period of time plasma FSH levels were elevated was greater than in the HA groups (P < 0.01). In the IVP trial, FSH-treated cows had a greater proportion of medium-sized (6–10 mm) follicles than controls (P < 0.001). Also, numbers of follicles (P = 0.01) retrieved (control: 13.1 ± 1.0; F200: 16.5 ± 1.2; F200HA: 19.5 ± 2.1; F300HA: 15.4 ± 1.4; P = 0.01) and blastocysts produced per ovum pickup session (control: 2.4 ± 0.5; F200: 3.7 ± 0.7; F200HA: 4.7 ± 0.7; F300HA: 3.1 ± 0.6; P = 0.06) were greater in cows receiving FSH, regardless of treatment. Cows in the F200HA group had a greater recovery rate (P = 0.009), number of COC cultured (P = 0.04), and blastocysts per ovum pickup session (P = 0.06) than cows in the F300HA group. In conclusion, superstimulation of Holstein donors before ovum pickup increased the efficiency of in vitro production. Additionally, a single IM dose of FSH in 0.5% HA resulted in similar plasma FSH profiles to twice-daily FSH treatment. Non-lactating donors treated with FSH produced more embryos per ovum pickup session regardless of FSH treatment. Lastly, all in vitro-produced endpoints were greater following a single dose of 200 mg of FSH in 0.5% HA than 300 mg of FSH in 0.5% HA.

Abstract:

Chinese forest frog ovum oil is a medicinal food high in cholesterol. In the current study, we evaluated the relative efficiency of β-cyclodextrin, crosslinked β-cyclodextrin, and silica gel adsorption on cholesterol removal from Rana chensinensis ovum oil. Beta-cyclodextrin had the highest cholesterol reduction rate (60.84 ± 4.45%) among the three methods. We further evaluated the efficiency of cholesterol removal by beta-cyclodextrin in the presence of ethanol and higher (55°C) temperature. This resulted into cholesterol removal rate of as high as 76%. Interestingly, monounsaturated fatty acids increased from 4.96% to 29.12% after cholesterol removal. We conclude that beta-cyclodextrin is an excellent adsorbent for removing cholesterol from ovum oil.

Abstract:

Among internal fertilizers, typically fewer than 1% sperm survive the journey through the oviduct. Several studies suggest that the sperm reaching the ovum—the ‘fertilizing set’—comprise a non-random sub-population, but the characteristics of this group remain unclear. We tested whether oviductal selection in birds results in a morphologically distinct subset of sperm, by exploiting the fact that the fertilizing set are trapped by the perivitelline layer of the ovum. We show that these sperm have remarkably low morphological variation, as well as smaller head size and greater tail length, compared with those inseminated. Our study shows that the morphological composition of sperm—rather than length alone—influences success in reaching the ovum.

Abstract:

Familial early-onset Alzheimer’s disease (AD) is more probable in individuals coming from mothers diagnosed with AD than from fathers diagnosed with AD. Studies in animal models have shown maternal imprinting due to the transmission to the embryo of altered material in the ovum. In the case of transgenic animals harboring a mutated form of the human amyloid precursor protein (APP), offspring from crosses with wild-type (WT) fathers and transgenic mothers display more abnormalities than offspring from crosses with transgenic fathers and WT mothers. Expression of the mutated APP in the ovum may lead to alterations that may be genetic and/or epigenetic in the nuclear and/or the mitochondrial DNA. These modifications that are transmitted to the new living beings affect more mitochondrial proteins and, therefore, the mitochondrial function may be affected in adulthood by trends present in the ovum.

For some years now, reproductive medicine has been capable of performing the act of human procreationin vitro, fusing the female ovum and the male semen outside of the human body. The embryo created by this process is then “implanted” into the uterus of the woman who had previously provided the ovum. This technique serves to overcome certain physical defects - such as a malfunction of the fallopian tubes - of a couple that wants to have children.
