Abstract

The structure of follicular tissue affects the ability to maintain the structural integrity of follicles against cryoinjury post-vitrification. Histological analysis was conducted on the structural integrity of each stage of preantral follicles post-vitrification using 7.5% and 15.0% doses of ethylene glycol (EG), and ovarian sections with HE staining were observed using an Olympus CX21 microscope connected to Optilab 3.0 lens and Image Raster software. Analysis was conducted on the ovarian cortex in the tracing line area using polygon measure tools to obtain follicle density (follicles/mm2) and follicle index (%) data. The result showed that the EG group 7.5% (KP1) increased follicle density compared to the vitrified group (KKV) in primordial (15.83±1.77) and primary (22.94±8.51) stages. Meanwhile, KP2 (EG 15%) was in primordial (41.92±6.45), primary (11.69±1.95), secondary (33.48±3.63), and tertiary (5.93±0.69) stages. KP1 increased grade 3 follicle index compared to KKV in primary (27.66±2.34), secondary (32.41±6.99), and tertiary (25.00±5.00) stages. Meanwhile, KP2 was in primary (26.87±6.68) and tertiary (25.00±5.00) stages. Both doses of 7.5% and 15.0% EG were able to maintain structural integrity at certain stages of preantral follicles. Secondary and tertiary follicles are the best stages in maintaining grade 3 follicular integrity with the addition of 7.5% EG.

Abstract

Protease contributes significantly to various industrial sectors, as shown by its increasing demand. An indigenous previously isolated bacteria, Bacillus halodurans CM1, is a wild-type bacterium whose ability to produce alkalotermophilic protease. In this study, the transformation of methylated pBBRE194 plasmid containing alkaline protease gene from this strain (PBBRE194-prot-CM1) into itself using a conjugation approach was conducted, and the measurement of the alkaline protease activity of the recombinant bacterium was carried out. The recombinant B. halodurans CM1 has been verified to carry the methylated pBBRE194 prot-CM1 by examining its ability to degrade protein in media containing skim milk and tetracycline, but also by amplifying tetracycline resistance gene sequence with 1,024 bp length of plasmid pBBRE194 prot-CM1 by PCR method from the recombinant bacterium. The results confirmed that recombinant B. halodurans CM1 was positively harboring plasmid pBBRE194 prot-CM1. Alkaline protease produced by recombinant CM1 reached higher activity than wild type between 18-36 h of cultivation. The alkalotermophilic wild type B. halodurans could accept the recombinant plasmid into their cells via conjugational transformation is firstly reported to our further knowledge.

Abstract

This study aims to describe the molecular characteristics of DNA barcodes in chocolate hind grouper (Cephalopholis boenak) in Indonesian waters with new sequence records from Madura Island waters. Partial sequences of the cytochrome c oxidase 1 (CO1) gene were successfully obtained from two samples of C. boenak in Madura Island waters. In contrast, the other sequences were obtained from the BOLD system database, covering the Islands of Bali, Lombok, and Ambon waters. The overall molecular analysis involved 10 C. boenak sequences with a length of 625 bp. The results indicated that the population of C. boenak in Indonesia waters has high genetic diversity, as evidenced by the value of haplotype diversity (Hd) = 0.956 and nucleotide sequence diversity (Pi) = 0.01746, in which the population is distributed into eight haplotypes. Results of phylogenetic tree reconstruction of neighbor-joining and maximum-likelihood indicate similar topology. The branching of NJ and ML phylogenetic trees of C. boenak in Indonesia waters is grouped into two geographical clades. Clade 1 with the subpopulations of the waters from Madura, Bali, and Lombok Islands. Clade 2 with the subpopulations of the waters from Ambon Island. The results of the median-joining network reconstruction depicted a similar topology with both phylogenetic trees.

Abstract

Cryopreservation is a technique for storing cells and tissues at very low temperatures for the possible usage of the stored cells and tissues throughout the year. Sperm cell cryopreservation in some species causes a decrease in sperm quality and DNA damage. Inappropriate cryopreservation protocols can cause changes in sperm physiology. Mitochondria are organelles that play a role in producing energy for sperm motility. Mitochondria have DNA molecules with small sizes compared to structures from nuclear DNA. This study analyzed the effect of cryopreservation on sperm motility and the Cytochrome Oxidase1 (COI) gene. The CO1 gene in mitochondrial DNA plays a role in energy production for spermatozoa motility. The cryopreservation was performed using skim milk and 10% methanol cryoprotectant, and the temperature in the equilibration process was 4-5°C for 10 minutes. Cryopreservation took place for 14 days in the freezer at -80°C. In addition, the thawing process was performed for 1-2 minutes at 40°C. This study found that the number of lesions per 10 kb in the CO1 gene in post-equilibration spermatozoa was (9.24±3.74), and post-thawing spermatozoa (was 10.26±7.54). Spermatozoa motility was obtained in fresh spermatozoa, i.e., 87±1.5%, post-equilibration spermatozoa 79±4.5%, and post-thawing spermatozoa 30±3.2%. This study concluded that cryopreservation of spermatozoa causes CO1 gene lesions and that in cryopreserved spermatozoa, there is a decrease in spermatozoa motility compared to fresh spermatozoa.
