Abstract:

The integrity of sperm deoxyribonucleic acid (DNA) and chromatin is very important for genetic material transmission into offspring. Therefore, the aim of the present study was to investigate the correlation between sperm deoxyribonucleic acid integrity and sperm parameters. The current study was conducted on 96 semen samples. This study was done at the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies, Al-Nahrain University for the period between November 2020 and May 2021. The samples were collected, and seminal fluid analysis was performed according to World Health Organization guidelines. Sperm Chromatin Dispersion test was performed. The results showed that the deoxyribonucleic acid fragmentation of sperms in infertile men in this study was higher than reported in fertile men in previous studies indicating that deoxyribonucleic acid fragmentation (DNA) is actively contributing at least partially to male infertility. In terms of enrolled men, sperm deoxyribonucleic acid fragmentation (SDF) showed significant positive correlation with round cell count.

Abstract:

There are an increasing number of applications that have been developed for oligonucleotide-based biosensing systems in genetics and biomedicine. Oligonucleotide-based biosensors are those where the probe to capture the analyte is a strand of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or a synthetic analogue of naturally occurring nucleic acids. This review will shed light on various types of nucleic acids such as DNA and RNA (particularly microRNAs), their role and their application in biosensing. It will also cover DNA/RNA aptamers, which can be used as bioreceptors for a wide range of targets such as proteins, small molecules, bacteria and even cells. It will also highlight how the invention of synthetic oligonucleotides such as peptide nucleic acid (PNA) or locked nucleic acid (LNA) has pushed the limits of molecular biology and biosensor development to new perspectives. These technologies are very promising albeit still in need of development in order to bridge the gap between the laboratory-based status and the reality of biomedical applications.

Abstract:

Deoxyribonucleic acid (DNA) is composed of a deoxyribose backbone, the three position (3') of each deoxyribose being linked to the five position (5') of the next by a phosphodiester bond. At the two position each deoxyribose is linked to one of four nucleic acids; the purines adenine or guanine or the pyrimadines thymine or cytosine. Each DNA molecule is made up of two such strands in a double helix with the nucleic acid bases on the inside. The bases pair by hydrogen bonding, adenine (A) with thymine (T) and cytosine (C) with guanine (G). Deoxyribonucleic acid is replicated by separation of the two strands and synthesis by DNA polymerases of new complementary strands. With one notable exception, the reverse transcriptase produced by viruses, DNA polymerases always add new bases at the 3' end of the molecule. Ribonucleic acid (RNA) has a structure similar to that of DNA but is always single stranded. The backbone consists of ribose, and uracil is used in place of thymine.

Abstract:

Deoxyribonucleic Acid Primer Design is an important factor in the success of the Polymerase Chain Reaction process because it will determine the value of Guanine and Cytosine content and Melting temperature for the genome amplification process in the adequacy of research data. To get a good primer design, a simulation process is needed to get the desired results, namely Guanine and Cytosine content between 50%-60%, Melting temperature 50o -65oC, a minimum length of 70 base pair sequences and the temperature difference between the forward primer and reverse primer less than 5oC. Usually researchers use the Primer3plus or NCBI Primer-BLAST software to get the Deoxyribonucleic Acid Primer Design results. Because there are limitations in the use of the software, the researchers, researchers want to use software that are suitable for current and future research needs. For this reason, a new algorithm model is needed to make software to support the needs of researchers. The method used in the algorithm model is to use Start Codon ATG and Stop Codon TAA, TAG and TGA with sequence lengths of 18, 21 and 24 base pairs. The raw data used is the Deoxyribonucleic Acid of the Typhonium Flagelliforme plant which has potential anti-cancer compounds. The new algorithm model resulted in 22 (twenty two) Deoxyribonucleic Acid Primer Design options, all of which met the data constraints and research requirements.

Abstract:

DNA methylation is one of the most important epigenetic mechanisms involved in gene silencing. Waves of DNA de- and re-methylation occur during mammalian preimplantation development. Whether the same happens in porcine parthenogenetic embryos has never been determined, and we set out to investigate this question. Porcine oocytes were aspirated from antral follicles, matured in vitro for 42 h, parthenogenetically activated and fixed in 4% paraformaldehyde at the 1-, 2-, 4-, and 8-cell stage as well as at the early and late blastocyst stage. The degree of DNA methylation was assessed by immunocytochemical staining (Anti-5MetC mouse monoclonal; Abcam, Copenhagen, Denmark) and DNA was counterstained with Hoechst 33258. Porcine fetal fibroblasts were used as standard. The fluorescent signals were detected using an epifluorescence microscope (Leica) and a Leica camera set at fixed exposure times. Signals were quantified using NIH ImageJ sofware. Total means of intensities (methylation and DNA) were calculated and exponential curves were obtained using Microsoft Excel-based statistics. DNA methylation and DNA content were highly correlated in porcine fetal fibroblasts demonstrating the effect of an immediate maintenance methylation taking place during the DNA S-phase of the cell cycle. A similar correlation was observed in the parthenogenetic embryos at all the developmental stages. The level of DNA methylation increased slightly from the early to the late 1-cell stage, and a pronounced increase in DNA methylation level was noted at the 2-cell stage. At the late 1-cell stage, the DNA methylation level of the two pronuclei was similar probably due to the maternal origin of both pronuclei. At the 4-cell stage, DNA methylation had decreased again but was higher compared with other developmental stages, except the 2-cell stage, and at the 8-cell stage, the level of DNA methylation reached a minimum. Subsequently, the level of DNA methylation increased slightly at the blastocyst stages. In conclusion, DNA methylation and DNA content were correlated in porcine fetal fibroblasts and parthenogenetic embryos. Furthermore, the levels of DNA methylation in parthenogenetic embryos exhibited an increase to the 2-cell stage followed by a decrease to the 8-cell stage and a final increase to the blastocyst stage. The initial increase in methylation to the 2-cell stage is different from what has been reported previously for in vivo derived porcine embryos. We are thankful to H. Holm and J. Nielsen for excellent technical assistance. This project was supported by Marie Currie Action project MRTN-CT-2006-35468 (CLONET).

Abstract:

ABSTRACT Background In clinical microbiology several techniques have been used to identify bacteria. Recently, Deoxyribonucleic acid (DNA)-based techniques have been introduced to detect human microbial pathogens in periodontal diseases. Deoxyribonucleic acid probes can detect bacteria at a very low level if we compared with the culture methods. These probes have shown rapid and cost-effective microbial diagnosis, good sensitivity and specificity for some periodontal pathogens in cases of severe periodontitis. Materials and methods Eighty-five patients were recruited for the study. Twenty-one subjects ranging between 22 and 48 years of age fulfilled the inclusion and exclusion criteria. Seventy-eight samples became available for DNA probe analysis from the deepest pockets in each quadrant. Results All 21 patients showed positive results for Prevotella intermedia; also, Prevotella gingivalis was identified in 19 subjects, Aggregatibacter actinomycetemcomitans in 6 subjects. P. intermedia was diagnosed positive in 82% of the subgingival samples taken, 79% for P. gingivalis, and 23% for A. actinomycetemcomitans. Conclusion This study shows a high frequency of putative periodontal pathogens by using DNA probe technology, which is semi-quantitative in this study. Deoxyribonucleic acid probes can detect bacteria at very low level about 103 which is below the detection level of culture methods. The detection threshold of cultural methods. Clinical significance The three types of bacteria can be detected rapidly with high sensitivity by using the DNA probe by general practitioners, and thus can help in the diagnosis process and the treatment.

Abstract:

A nonlinear multi-image encryption scheme is proposed by combining the reality-preserving discrete fractional angular transform with the deoxyribonucleic acid sequence operations. Four approximation coefficients of the four images are extracted by performing the two-dimensional lifting wavelet transform. Then, the four approximation coefficients are synthesized to generate a real-valued output with the reality-preserving discrete fractional angular transform. Finally, based on the deoxyribonucleic acid operation and the Logistic-sine system, the real-valued intermedium output will be encrypted to yield the final ciphertext image. To enhance the security of the image encryption algorithm, the initial value of the chaotic system is calculated by the 256-bit binary sequence, which is obtained by taking the statistics information of the plaintext images as the input of SHA-256. Deoxyribonucleic acid sequence operations, as nonlinear processes, could help to improve the robustness of the cryptosystem. Simulation results and security analysis demonstrate the effectiveness of the image encryption algorithm and the capability of withstanding various common attacks.

Abstract:

<p style='text-indent:20px;'>In this research paper, the modified Khater method, the Adomian decomposition method, and B-spline techniques (cubic, quintic, and septic) are applied to the deoxyribonucleic acid (DNA) model to get the analytical, semi-analytical, and numerical solutions. These solutions comprise much information about the dynamical behavior of the homogenous long elastic rods with a circular section. These rods constitute a pair of the polynucleotide rods of the DNA molecule which are plugged by an elastic diaphragm that demonstrates the hydrogen bond's role in this communication. The stability property is checked for some solutions to show more effective and powerful of obtained solutions. Based on the role of analytical and semi-analytical techniques in the motivation of the numerical techniques to be more accurate, the B-spline numerical techniques are applied by using the obtained exact solutions on the DNA model to show which one of them is more accurate than other, to explain more of the dynamic behavior of the homogenous long elastic rods, and to show the coincidence between the different types of obtained solutions. The obtained solutions verified with Maple 16 & Mathematica 12 by placing them back into the original equations. The performance of these methods shows the power and effectiveness of them for applying to many different forms of the nonlinear evolution equations with an integer and fractional order.</p>

Abstract:

Several representative strains of Haloarcula vallismortis, Haloarcula hispanica, and other Haloarcula species not currently accepted as valid species were examined for genetic relatedness to each other and to members of other halobacterial species. The G + C content of DNA of the 11 strains of the genus Haloarcula tested ranged between 56.9 and 66.3 mol%. The G + C contents obtained for Haloarcula vallismortis and Haloarcula hispanica were 56.9–64.3 mol%, and 58.7–66.3 mol%, respectively. The results of our DNA–DNA hybridization experiments indicate that Haloarcula vallismortis and Haloarcula hispanica are composed of strains with high DNA homology, constituting genotypic species that correlate with the previously reported phenotypic features. However, our results do not support the separation of "Haloarcula californiae," "Haloarcula sinaiiensis," "Halobacterium marismortui," and "Amoebobacter morrhuae" in different taxonomic taxa, since high DNA homology was obtained between these strains and representatives of species of the genus Haloarcula.Key words: archaebacteria, halobacteria, Haloarcula, DNA homology, nucleic acids hybridization.

Abstract:

Interactions with many clinically active therapeutic agents with DNA are well studied and it is necessary to decipher the structure of DNA and to investigate the pathological implications of those molecules in living organism. This study investigated the interaction of antidepressant drug Duloxetine-hydrochloride (DLX) with calf thymus DNA (ct-DNA). The interaction of DLX with ct-DNA was studied employing fluorescence spectroscopy. Hypochromic effect was found in the absorption spectra of duloxetine, and its wavelength had no shift in the presence of DNA indicating external binding mode of duloxetine to DNA. Fluorescence spectroscopic results showed the quenching of fluorescence intensity of DLX in presence of DNA indicating the interaction between DLX and DNA. Hydrophobic interaction and hydrogen bonding played the dominating role in DLX-DNA binding and binding forces also indicate the binding site of duloxetine to be at the minor groove of DNA.Dhaka Univ.

Abstract:

This article discusses dynamics of the fractal double-chain deoxyribonucleic acid model. This structure contains two long elastic homogeneous strands that serve as two polynucleotide chains of deoxyribonucleic acid molecules, bounded by an elastic membrane indicating hydrogen bonds between the base pairs of two chains. The semi-inverse variational principle and auxiliary equation method are employed to extricate soliton solutions. The collection of retrieved exact solutions includes bright, dark, periodic, and other solitons. The constraint conditions emerge naturally which ensure the presence of these solutions. Additionally, 2D and 3D graphs showing the impact of fractals on solutions are included. These plots use appropriate parameter values. Furthermore, sensitivity analysis of the considered model is also acknowledged. The outcomes reveal that these techniques are reliable, effective, and applicable to various biological systems.

Abstract:

Akhir-akhir ini bioprospeksi mikroorganisme laut semakin populer dan banyak diminati karena potensinya yang menjanjikan sebagai sumber komponen bioaktif baru. Identifikasi mikroorganisme merupakan salah satu tahapan yang penting dalam bioprospeksi. Perkembangan identifikasi mikroba diawali dengan identifikasi melalui ciri-ciri morfologi, fisiologi, dan metabolisme. Namun adanya kekurangan-kekurangan metode ini yaitu berupa ketidakakuratan dan waktu identifikasi yang lama menjadikan metode secara molekuler lebih berkembang. Pada bakteri, 16S ribosom deoxyribonucleic acid (rDNA) mempunyai daerah sekuen yang konservatif sehingga dapat digunakan untuk menduga hubungan kekerabatan secara alami antar spesies. Sedangkan pada kapang digunakan 18S rDNA dan daerah internal transcribed spacer (ITS) untuk identifikasinya. Tahapan identifikasi dengan metode molekuler meliputi ekstraksi deoxyribonucleic acid (DNA), amplifikasi DNA, sekuensing, analisis hasil sekuen, dan pembuatan pohon filogenetik. Balai Besar Riset Pengolahan Produk dan Bioteknologi Kelautan dan Perikanan (BBRP2B-KP) memiliki koleksi mikroba potensial penghasil enzim kitosanase, kitinase, dan protease dari berbagai sampel dari lingkungan laut. Berdasarkan pohon filogenetik beberapa isolat koleksi memiliki kemiripan 87–96% dengan Staphylococcus caprae, Stenotrophomonas maltophilia, Acinetobacter sp., Bacillus licheniformis, Geobacillus stearothermophilus.

Abstract:

Abstract This current study explored the effects of fine particulate matter (PM2.5) on deoxyribonucleic acid methylation in human bronchial epithelial cells. Human bronchial epithelial cells were exposed to PM2.5 for 24 h after which, deoxyribonucleic acid samples were extracted, and the differences between methylation sites were detected using methylation chips. Subsequent gene ontology functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed for the differential methylation sites. Functional epigenetic modules analysis of the overall differential methylation site interactions was also conducted. A total of 127 differential methylation sites in 89 genes were screened in the PM2.5 10 μg/ml group, of which 55 sites demonstrated increased methylation, with methylation levels decreasing in a further 72 sites. Following an exposure of 50 μg/ml PM2.5, a total of 238 differentially methylated sites were screened in 168 genes, of which methylation levels increased in 127 sites, and decreased in 111. KEGG analysis showed that the top 10 enrichment pathways predominantly involve hepatocellular carcinoma pathways and endometrial cancer pathways, whereas functional epigenetic modules analysis screened eight genes (A2M, IL23A, TPIP6, IL27, MYD88, ILE2B, NLRC4, TNF) with the most interactions. Our results indicate that exposure to PM2.5 for 24 h in human bronchial epithelial cells induces marked changes in deoxyribonucleic acid methylation of multiple genes involved in apoptosis and carcinogenesis pathways, these findings can provide a new direction for further study of PM2.5 carcinogenic biomarkers.

Abstract:

SUMMARYThe dominant repetitive deoxyribonucleic acid (DNA) sequence in the genome of a clone of Trypanosoma (Nannomonas) simiae has been identified and cloned as a recombinant plasmid. The recombinant plasmid was used in hybridization analyses of DNA samples obtained from various trypanosome species and subspecies. The results indicated that the T. simiae repetitive DNA sequence hybridized with DNA derived only from T. simiae; it did not hybridize with DNA derived from clones or stocks of T. congolense, or from any other trypanosome species examined. A preliminary characterization of the cloned DNA sequence and its use in the identification of T. simiae of similar genotypes are presented.

Abstract:

Current data storage technologies cannot keep pace longer with exponentially growing amounts of data through the extensive use of social networking photos and media, etc. The "digital world” with 4.4 zettabytes in 2013 has predicted it to reach 44 zettabytes by 2020. From the past 30 years, scientists and researchers have been trying to develop a robust way of storing data on a medium which is dense and ever-lasting and found DNA as the most promising storage medium. Unlike existing storage devices, DNA requires no maintenance, except the need to store at a cool and dark place. DNA has a small size with high density; just 1 gram of dry DNA can store about 455 exabytes of data. DNA stores the informations using four bases, viz., A, T, G, and C, while CDs, hard disks and other devices stores the information using 0’s and 1’s on the spiral tracks. In the DNA based storage, after binarization of digital file into the binary codes, encoding and decoding are important steps in DNA based storage system. Once the digital file is encoded, the next step is to synthesize arbitrary single-strand DNA sequences and that can be stored in the deep freeze until use.When there is a need for information to be recovered, it can be done using DNA sequencing. New generation sequencing (NGS) capable of producing sequences with very high throughput at a much lower cost about less than 0.1 USD for one MB of data than the first sequencing technologies. Post-sequencing processing includes alignment of all reads using multiple sequence alignment (MSA) algorithms to obtain different consensus sequences. The consensus sequence is decoded as the reversal of the encoding process. Most prior DNA data storage efforts sequenced and decoded the entire amount of stored digital information with no random access, but nowadays it has become possible to extract selective files (e.g., retrieving only required image from a collection) from a DNA pool using PCR-based random access. Various scientists successfully stored up to 110 zettabytes data in one gram of DNA. In the future, with an efficient encoding, error corrections, cheaper DNA synthesis,and sequencing, DNA based storage will become a practical solution for storage of exponentially growing digital data.

Abstract:

We aimed to summarize the current knowledge about the trends in cfDNA application based on the analysis of clinical trials registered until April 2021. International Clinical Trials Registry Platform (ICTRP) and Clinicaltrials.gov were searched with the keywords: “cf-DNA”; “Circulating DNA”; “Deoxyribonucleic Acid”; and “Cell-Free Deoxyribonucleic Acid”. Of 605 clinical trials, we excluded 237 trials, and 368 remaining ones were subject to further analysis. The subject, number of participants, and study design were analyzed. Our scoping review revealed three main trends: oncology (n = 255), non-invasive prenatal diagnostic (n = 48), and organ transplantation (n = 41), and many (n = 22) less common such as sepsis, sport, or autoimmune diseases in 368 clinical trials. Clinical trials are translating theory into clinical care. However, the diagnostic value of cfDNA remains controversial, and diagnostic accuracy still needs to be evaluated. Thus, further studies are necessary until cfDNA turns into a standard in clinical practice.
