Abstract

Stunting is a significant global public health problem caused by long-term dietary deficits that affect many children worldwide. Both environmental and genetic factors, including variants in the GHSR gene, play a crucial role in stunted growth. This study used an artificial recombinant plasmid DNA method to evaluate two primer set combinations for identifying DNA variants in the GHSR gene. Selecting suitable primer sets for identifying GHSR genetic variants linked to stunting is essential, as evidenced by PCR and sequencing techniques. The target gene, based on the GHSR reference sequence, consists of eight DNA variations (ΔQ36, G57G, P108L, L118L, R159R, C173R, D246A, and A277P). A recombinant plasmid was created by inserting a 1000 bp fragment of the GHSR gene into the pUC57 backbone. Primer sets were chosen based on their capacity to amplify these eight genetic variations and were optimized and validated using PCR methods. PCR and bi-directional sequencing verified the existence of surrounding DNA and specific single nucleotide variants (SNVs). In our study, we discovered four changes in the DNA sequence (R159R G>A, C173R T>C, D246A A>C, and A277P G>C) using the E1_F2/E1_R3 primer pair. Additionally, a new combination of primers (E1_F1/E1_R3) effectively detected seven DNA sequence mutations (ΔQ36 del CAG, G57G C>T, P108L C>T, L118L C>T, R159R G>A, C173R T>C, and D246A A>C). We have developed a new combination of forward and reverse primers to identify seven SNVs in the GHSR gene, which could serve as a diagnostic tool in clinical laboratory settings.

Abstract

The growing issue of bacterial resistance to conventional antibiotics has led to an increasing need for alternative antimicrobial agents. Chitosan, a biopolymer derived from marine organisms such as crustaceans (shrimp, crabs) and mollusks (shellfish), has shown significant antibacterial properties. This systematic review aims to evaluate the antibacterial activity of chitosan extracted from various marine sources against Gram-positive (Staphylococcus epidermidis) and Gram-negative (Escherichia coli) bacteria. A comprehensive search of studies published in the past decade was conducted across multiple databases, using predefined inclusion criteria to identify relevant experimental research that focused on quantitative data, such as inhibition zones. The review analyzes key variables, including chitosan extraction methods, concentrations, and experimental conditions. The results revealed that chitosan exhibited the highest antibacterial activity against E. coli, while S. epidermidis showed moderate susceptibility. Variations in antibacterial effectiveness were attributed to differences in chitosan extraction methods and experimental conditions. Despite these variations, the overall evidence supports the potential of chitosan as an effective antimicrobial agent, demonstrating significant inhibition against a wide range of bacterial strains. The findings suggest that chitosan may serve as a promising natural alternative to combat bacterial infections, particularly those caused by antibiotic-resistant pathogens. However, further research is needed to standardize extraction techniques, explore the antibacterial mechanisms, and conduct in vivo studies to validate its clinical applications. These findings underscore chitosan's potential as a sustainable and effective solution in addressing the global challenge of bacterial resistance.

Abstract

Huntington's Disease (HD) is a neurodegenerative disorder caused by a CAG triple expansion (>36) in the first exon of the HTT gene encoding the huntingtin protein. Advances in gene editing technologies, such as CRISPR-Cas9, provide new hope for correcting the genetic mutations underlying HD. This review article aims to review the potential and effectiveness of CRISPR-Cas9 technology as a therapeutic tool for HD. The writing method used was Systematic Literature Review, with literature searches conducted using three databases: PubMed, ScienceDirect, and SpringerLink. This study reviewed several studies that used in vivo and in vitro models to evaluate the impact of HTT gene editing on mutant huntingtin protein expression and HD symptoms. Results showed that CRISPR-Cas9 can effectively reduce mutant huntingtin protein expression, reduce neuronal toxicity, and improve motor symptoms in mouse models of HD. Although these results are promising, further studies are needed to optimize the safety and effectiveness of using CRISPR-Cas9 in genetic therapy for HD.

Abstract

The Muslim community has difficulties in determining the halal status of animal-derived items and their derivatives due to their extensive prevalence. Islamic customers are increasingly becoming more selective and are demanding halal certification for culinary goods. Developing a way to identify porcine DNA in goods is of utmost importance. The Cyt b gene is being used to evaluate swine DNA samples by using primer candidates. The process of generating primers utilizing bioinformatics tools, such as NCBI, MegaXI, Primer3Plus, SnapGene Viewer, and Net Primer websites, is utilized to assess and analyze the effectiveness of laboratory research. The study concluded that the primers effectively amplified pig DNA, but they were unsuccessful in amplifying chicken or beef DNA. After conducting in silico experiments, a total of 7 possible primers were generated. The most advantageous pair of primers was identified, which includes the forward primer 5'-AACATCCGAAATCACACCC-3' and the reverse primer 5'-AGAATGATATTTGTCCTCAGGG-3'. The efficacy of these primers was evaluated in a controlled laboratory environment. Results from the laboratory experiments demonstrate that these particular primers have the ability to amplify the Cyt b gene from the Sus scrofa species at a temperature of 58°C, producing a DNA fragment that is 415 base pairs long. DNA sequencing is essential to verify that the amplified DNA band matches to the Sus scrofa Cyt b gene. Keywords:          PCR, Porcine, Primer, Cyt b, Halal

Abstract

ABSTRACT Antibiotic resistance occurs when microorganisms become unresponsive to antibiotic treatment, rendering common therapies ineffective against infections. As a result, the infection becomes increasingly challenging to treat, posing a heightened risk of severe disease progression and increasing the risk of spreading the disease. The causes of the emergence of antibiotic resistance include a number of factors, including excessive use of antibiotics from self-medication, to inappropriate disposal of antibiotic drugs. Karawang Regency, a region in West Java which consists of 10 sub-districts and has a population of more than 2.4 million people. Research conducted in Karawang shows the potential for antibiotic resistance based on use and the environment. It is known that the people of Karawang Regency have poor knowledge and perception regarding antibiotic resistance and use, one of which is Pasir Jengkol village. Therefore, it is necessary to increase understanding of medicines among the people of Karawang Regency, including by socializing the DAGUSIBU movement (Dapatkan, Gunakan, Simpan dan Buang Obat) or Proper Use, Storage and Disposal of Medications and its implementation as a measure to prevent antibiotic resistance. The output of this activity is primarily an increase in understanding of public knowledge through questionnaires which are analyzed using statistics. The results obtained were then tested using a statistical test showing a significant influence (Sig 0.002) increase in knowledge through the difference in pre-test and post-test scores. This outreach activity, which provides educational materials on preventing resistance, has positively impacted the Pasir Jengkol community's knowledge. Therefore, this socialization initiative can be replicated in other areas, particularly in Karawang Regency. Keywords: Antibiotic,  Drug Resistance, DAGUSIBU, Karawang.

Abstract

The decision between probe-based and non-probe-based qPCR assays is crucial, influenced by diagnostic goals and sample characteristics. This review provides an in-depth evaluation of these two assay types, analyzing their principles, strengths, drawbacks, and applications. A thorough review of the literature, primarily sourced from PubMed, was undertaken to explore prominent assay systems, including TaqMan, KASP, rhAmp, HRM, and SYBR Green. Probe-based qPCR assays, exemplified by TaqMan and rhAmp, are distinguished by their high specificity, aptitude for multiplex analysis, and reduced risk of false positives, making them highly suitable for SNP genotyping and pathogen detection. However, their elevated costs and intricate design requirements remain significant challenges. Conversely, non-probe-based assays, such as SYBR Green and HRM, present cost-effective alternatives with straightforward designs. HRM, in particular, is effective in identifying genetic variations like SNPs with remarkable sensitivity. Nonetheless, these methods are susceptible to non-specific amplifications, requiring careful optimization to maintain reliability. The selection of a suitable qPCR assay depends on various factors, including precision, affordability, and multiplexing capabilities, with applications spanning infectious disease detection and genetic disorder analysis. This review emphasizes the indispensable role of qPCR in molecular diagnostics while showcasing recent technological advances that aim to mitigate existing constraints and enhance diagnostic precision and accessibility.

Abstract

Parkinson's disease is a degenerative nervous system disorder caused by the death of dopamine-producing cells in the substantia nigra. Dopaminergic treatment could alleviate motor symptoms for a period. One of the effective dopaminergic medications for symptomatic relief was Levodopa and dopamine agonists. Clinically, Levodopa was always combined with Dopa Decarboxylase (DDC) inhibitors, which redirected Levodopa metabolism towards the COMT pathway, increasing its bioavailability in the central nervous system. The purpose of this article was to investigate the relationship between COMT and MAO-B gene polymorphisms and Levodopa in Parkinson's disease patients, starting by gathering literature on the association between COMT and MAO-B polymorphisms and Levodopa in Parkinson's disease patients using various databases. Reviewed literature revealed that the most frequent polymorphism in the COMT gene was rs4680. Some polymorphisms significantly impacted the treatment of Parkinson's disease patients. However, despite efforts to identify genetic factors influencing the risk of side effects or treatment ineffectiveness, the role of pharmacogenetics in Parkinson's disease has not been fully explored and lacks consistent clinical recommendations. Further research was needed to tailor treatment to individual polymorphisms so that pharmacogenomic approaches could be applied more consistently

Abstract

Reliable clinical diagnosis of Single Nucleotide Polymorphisms (SNPs) is necessary for personalizing tamoxifen medication according to CYP2D6*10 genetic variations. Our research aimed to create a recombinant plasmid for external control material with a molecular size of 3812 bp. The recombinant plasmid was achieved by cloning an 838 bp gene insert of CYP2D6*10 rs1065852 into a 2974 bp pJET1.2 plasmid into Escherichia coli DH10B and selection on ampicillin agar medium. Isolated E. coli recombinants provided the plasmid molecules for analysis. Bi-directional sequencing and Real-Time PCR confirmed the presence of wild-type and mutant rs1065852 DNA fragments in the plasmid, namely homozygote CC and TT. The conclusion is that we have successfully introduced a novel recombinant plasmid developed by cloning the SNP rs1065852, which carries the 100C>T mutation, using pJET 1.2/blunt system, which could significantly enhance the accuracy of clinical SNP diagnostics for personalized medicine in breast cancer treatment.
