ABSTRACT
Meat adulteration and admixing are prevalent malpractices observed in processed and raw meat samples, where the consumption of adulterated meat has been associated with food allergies, financial losses, and consumer distrust. Meat authentication is pivotal to address these concerns. The meat authenticity can be determined through genetic, protein, and immunological markers and advanced detection methods. However, these methods often target a single species and lack the specificity to distinguish closely related species. Here, in the present study, we have developed a multiplex detection method based on the species-specific primers and probes, that can target four meat species in one reaction. The developed method amplifies the mitochondrial genomic regions of chicken, pork, sheep and goat using TaqMan multiplex probe-based RT-qPCR assay. Unique pairs of species-specific primers and probes that target specific mitochondrial DNA (mtDNA) regions of each species were designed and screened for specificity and sensitivity. The detection limit for species identification using the designed primers in real-time qPCR assays was 0.1 picogram per microliter (pg/µL) DNA detected in singleplex reaction and facilitates the simultaneous detection of closely related species, such as goat and sheep. Further, DNA-based probes were utilized in a multiplex real-time qPCR assay to identify chicken, pork, sheep and goat DNA in a single tube reaction. The multiplex assay was validated for raw and processed meat products, demonstrating its applications in ensuring the quality of meat products and safeguarding consumer interests.
ABSTRACT
OBJECTIVE: To determine and compare the clinical outcome of Cyriax manipulation and traditional physical therapy for the treatment of cervical discogenic problems in terms of pain, range of motion and disability. METHODS: The randomised controlled trial was conducted at Benazir Bhutto Hospital, Rawalpindi, Pakistan, from January to June, 2018, and comprised patients having prolapsed intervertebral disc with neck or arm pain who were then randomly allocated into control and experimental groups using the sealed envelope method. The control group received cervical isometrics 10 repetitions ×1 set, 4 days/week and targeted muscle strechings 10 repetition × 1 set/day for 4 days/week. The experimental group received 10 min pre-manipulative massage and Cyriax manipulation protocol. Data was analysed using SPSS 20. RESULTS: Of the 40 subjects, there were 20(50%) in each of the two groups. The experimental group showed significance difference in terms of numeric pain rating scale, range of motion and the neck disability index (p<0.05 each). CONCLUSIONS: Cyriax manipulation was found to be significantly better than the traditional treatment of physiotherapy for cervical discogenic pain.
