Abstract

Sperm motility is the main problem for honeybee's reproduction both in natural and in artificial insemination. Sperm produced only by sexually mature drone. Drone with high semen volumes can be seen by the external morphology like hairy in back and the existence of yellow stripes on their black abdomen. Semen samples were collected from the drone by the massage technique; these consist of massaging the abdomen of drone. This massage proceeded until penis and semen cream to yellow color, was produced. Semen taken out with spuit (3 ml) that contain a modification dilution media called "Kiev". Semen samples were collected; volume, abnormalities and motility were measured. The sexually mature drones were observed in 99.06% (213/215) drones with rare hair in back and 76.28% (164/215) with existence of the yellow stripes in the black abdomen. The color of sperm is yellowish white, which is different from mucous that is white. The average volume of semen samples from each drone is 1.11 μl. The average length of sperm is 217.57 μm (107.50-412.50 μm). The average length of sperm is 7,52 μm (5-1O μm). It's flipped tails, broken tails, double tails, and double heads with an average of 19.83%, 12.75%, 6.42%, and 2,25% respectively can determine abnormalities of the sperm. To conduct the artificial insemination, drone sperm should always be available. For this reason sperm should be preserved in an optimal condition storage temperature (5°C, 27 °c and 37°C) and glucose concentration (0%, 0,3%, 0,6%, and 0,9%) containing in the dilution media. This condition can be affecting the sperm motility. The highest motility is achieved when the sperm is kept in 0,9% glucose concentration and storage in 5 °C temperature. In this condition 0.19x106 sperm/ml can survive up to 36 hours. Moreover, the higher concentration of sperm motility up to 36 hours is achieved when sperm is kept in 5 Celsius temperature with different leves of glucose in dilution media. However statistically interaction between glucose concentration and temperature levels does not give significant affects.

Abstract

Naturally, mammalian embryo resulting from the fertilized oocytes by sperm and develops to the zygote with diploid chromosome. Through the embryo engineering, mammalian embryo also could be produce by: nuclear transfer and parthenogenesis. Embryo produce by nuclear transfer method could develop to term with very limited results. However, parthenogenetic embryos could not develop to term because of the incorrect expression of imprinted genes (genomic imprinting).........

Abstract

The process of freeze drying caused detrimental effect on plasma membrane and acrosome of the spermatozoa, even it potentially could alter the chromatin and DNA integrities. On the other hand, DNA integrity is essential for spermatozoa to participate in pronucleus formation during fertilization event. Therefore the evaluation of DNA integrity should be carried out to study the effect of freeze drying process. EDTA, EGTA, and PBS were used as dilution media of spermatozoa prior to freeze drying process to protect the DNA. Toluidine blue staining and comet assay methods were used to evaluate the alteration on chromatin and DNA integrities of spermatozoa, respectively. The results revealed that the highest compacted chromatin after 6 months storage of freeze-dried spermatozoa were observed from EGTA-3 (98%) and EGTA-1 (97%) treatments that had significant differences compared to all PBS treatments (90-92%), but not for fresh spermatozoa (100%). Whereas, the highest compacted DNA integrity of freeze-dried spermatozoa were observed from EGTA-2 (92%) and EGTA-3 (92%) but had no significant differences compared to other treatments including fresh spermatozoa (97%). These results demonstrate that EDTA and EGTA tend to be able to protect chromatin and DNA integrities of ram spermatozoa during freeze-drying and storage compared to PBS.

Abstract

Ram spermatozoa are sensitive to extreme changes in temperature during the freeze-thawed process. The present study was conducted to examine the effects of addition of various sugars in Tris extender on sperm cryosurvival of Garut ram. Semen was collected using an artificial vagina from three mature rams once a week. Immediately after initial evaluation, semen was divided into five parts and diluted with Tris extender (control), Tris extender + 0.4% dextrose, Tris extender + 0.4% raffinose, Tris extender + 0.4% trehalose, and Tris extender + 0.4% sucrose, respectively. Semen was loaded in to 0.25 ml mini straw with the concentration of 200 million or 800 million motile spermatozoa per ml. Semen was equilibrated at 5oC for three hours, then frozen and stored in liquid nitrogen for seven days. Quality of processed-semen including percentages of motile spermatozoa (MS), live spermatozoa (LS), intact acrosome cap (IAC), and intact plasma membrane (IPM) were evaluated after dilution, equilibration, and thawing, respectively. Data were analyzed using completely randomized design with five treatments and six replicates. Means were compared significant difference test at 0.05 significant level. Results of this research showed that there was no significantly difference (P>0.05) between treatments for all sperm quality parameters after dilution and equilibration. Mean percentages of post thawing MS, LS, IAC, and IPM for dextrose (54.00; 68.00; 66.60, and 57.83%), raffinose (50.00; 64.33; 61.80, and 61.75%), trehalose (50.83; 65.67; 61.40 and 57.75%), and sucrose (49.00; 66.80; 58.50 and 58.50%) were significantly (P<0.05) higher than control (40.83; 52.67; 54.60, and 49.40%) respectively. In conclusion, addition of 0.4% dextrose, raffinose, trehalose or sucrose in Tris extender are effective in improving frozen semen quality of Garut ram.

Abstract

Human Wharton’s jelly‐mesenchymal stem cells (hWJ‐MSC) are an emerging potential source of stem cells derived from the umbilical cord. Previous studies have shown their potential as treatment for traumatic brain injury and Parkinson’s disease. However, no study has yet investigated the effect of hWJ‐MSC injections in countering spatial learning and memory impairment in aging rats. The effect of hWJ‐MSC injection on young rats is also unknown. The objective of this research was to analyze the effect of an hWJ‐MSC injection on spatial learning, memory, density of putative neural progenitor cells (pNPC), and neuronal apoptosis in the dentate gyrus (DG) of young and aging rats. Injection of hWJ‐MSC did not change spatial learning and memory in young rats until two months post‐injection. This might be due to retained pNPC density and neuronal apoptosis in the DG of young rats after injection of hWJ‐MSC. In contrast, injection of hWJ‐MSC promoted both spatial learning and memory in aging rats, a finding that might be attributable to the increased pNPC density and attenuated neuronal apoptosis in DG of aging rats during the two months post‐injection. Our study suggests that a single injection of hWJ‐MSC might be sufficient to promote improvement in long‐term learning and memory in aging rats.

Abstract

Sex determination in turtle species is not only based on genotype, but also rely on the incubation temperature. In addition, sexual differentiation takes place during the thermo-sensitive period (TSP). This study was conducted to determine the effects of incubation temperature on sex expression profile of determination gene, bioreproduction, phenotype, and locomotory performances  of olive ridley turtle hatchlings. Fertile eggs incubated at two temperatures, namely feminine temperature (30-33°C), and masculine temperature (26-27°C). Value of cycle threshold (CT) measured during TSP, i.e 23-25 embryonic development stage, and after TSP, i.e 26-27 embryonic development stage using real time PCR techniques. Comparison of gene expression at both incubation temperatures were analyzed by ANOVA, and Student’s t test. Hatchling bioreproduction and phenotype measurement consist of the incubation period, embryo growth, morphometrics, and locomotori performances hatchlings were analyzed with regression analysis and Student’s t test. The results showed expression of both aromatase and Rspond 1 genes (which plays a role in ovarian differentiation) after the TSP that incubated at feminine temperature higher and different with masculine temperature. In conjunction with the  bioreproduction and phenotype, the incubation period of feminine temperature shorter than that of masculine. Likewise, growth of the embryo of feminine temperature was faster than that of masculine. Incubation at feminine temperature significantly affect to carapace width, length and width of the plastron, long flippers and rear arms, long neck, and the frequency of the swing flippers.

Abstract

Reproductive technologies including in vitro fertilization (IVF), embryo manipulation, gamete and embryo freezing, thawing and embryo transfer were rapidly developed. Vitrification is an embryo freezing technique that is the most developed. In this experiment, we vitrified mouse embryos and then examined the embryos i.e: (i) the quality of the embryos after thawing, (ii) the implantation rate of the embryos and (iii) viability of the embryos in vivo. Morulae and blastocycsts were collected from female mice that were pregnant a day 3,5. The embryos were equilibraten in mPBS +10% etilene glycol. Vitrification was carried out by using VABEDS medium, containing 6-10 embryos that were dropped into a tip of a straw, then frozen in liquid nitrogen for 24 hours. Thawing was carried out by flushing the embryos using mPBS suplemented with 0.5, 0.25, 0.1 and 0 M sucrose. After being incubated in M2 medium at 37oC for 1-2 hours, the recovery embryos were then transferred into the uteri of day 2.5 of pseudopregnat females. The females were then sacrificed at day 16 of gestation and the total implantaion, total life and death fetuses, as well as resorpted embryos, were taken as data. The results showed that vitrification significantly (p<0,05) reduced the quality of the embryos, as well as their implantation rate and the viability of the fetuses, which may be caused by the unoptimal combination of the cryoprotectant in the vitrification medium, temperature and exposure time during vitrification.

Abstract

The aim of this study was to evaluate the concentration, progressively motile, and percent live sperm in the various regions of epididymis and ductus deferens after preservation at 4oC. Epididymis and ductus deferens were collected from 21 epididymis and ductus deferens of domesticated cat (Felis catus) by castration. One testicle of pair (control testicle) was analyzed at the day of castration, while the other testicle of the pair was stored at 4oC up to 7 days. The sperm concentration, percentage of sperm motility and live sperm were examined daily until day-7 of preservation. The sperm concentration was higher (p<0.05) in cauda epididymis (23.99x106 sperm/ml) and ductus deferens (25.42x106 sperm/ml) than caput (11.51x106 sperm/ml) and corpus epididymis (14.82x106 sperm/ml). The percentage of sperm motility and live sperm decreased (p<0.05) during preservation period. However, the percentage of motile (11.33 to 16.00 %) and live (15.05 to 20.20 %) sperm could be found in preserved epididymis and ductus deferens up to day-7. These results show that motile and live sperm can be collected from cat’s epididymis and ductus deferens up to day 7 after preservation at 4oC.

Abstract

Female reproductive system showing the fastest signs of aging. The ovarian aging characterized by a decrease in follicular development. Stem cells are undifferentiated cells and can form a variety of different cells as the foundation of tissues and organs. Previous studies reported that Bone Marrow Mesenchymal Stem Cells (BM-MSCs) transplantation can restore follicular development in damaged ovarian rats. This study aimed to analyze the number of follicular development in aged rats and to analyze the capability of human Umbilical Cord Mesenchymal Stem Cells (hUC-MSCs) to improving follicular development in aged rats. This study used 3 mature rats (4 months old), and 9 nine aged rats (22-24 months old), Spraque Dawley (SD) strain. They were divided into four groups. The first and the second group was mature rats and aged rats without injection. The third and the fourth group was aged rats injected hUC-MSCs dose 106 cells/kgBW and hUC-MSCs dose 107 cells/kgBW. The injection carried out 4 times at 3-month intervals. The parameters observed were follicular development and homing image of hUC-MSCs in ovarian tissue. The results showed that the number of follicular developments in aged rats 22-24 months decreased significantly compared to mature rats 4 months old. Injection of hUC-MSCs at dose 106 cells/kgBW and 107 cells/kgBW did not increase follicular development in aged rats. hUC-MSCs did not found in ovarian tissue. It could be concluded that aged rats 22-24 months old no longer productive indicated from the number of follicular developments and corpus luteum decreased. The injection of hUC-MSCs intravenously did not indicate an improvement of follicular development in aged rats 22-24 months old.
