Cervicothoracic junction mobilization versus autogenic muscle energy technique for chronic mechanical neck pain: A randomized controlled trial.

OBJECTIVE: Neck pain is a prevalent global health concern often accompanied by musculoskeletal symptoms. This randomized controlled trial attempted to contrast the impacts of non-thrust Maitland mobilization and Autogenic inhibition muscle energy technique on chronic mechanical neck pain associated with cervico-thoracic junction hypo-mobility. METHODS: Sixty participants (24 males and 36 females, aged 18-45 years) were allocated randomly into three equally sized groups (A, B, C). Group A: Maitland mobilization plus conventional treatment, Group B: Autogenic Muscle energy technique plus conventional treatment, while; Group C solely received conventional treatment. Treatment was administered for four weeks, three times a week. Outcome measures: neck pain (The primary outcome measure) assessed by Visual Analog Scale (VAS), disability evaluated through Neck Disability Index (NDI), active range of motion (AROM), and joint position error (JPE) as an indicator of cervical proprioception. All measures were assessed both at baseline and after four weeks of intervention. RESULTS: Results showed significant improvements in VAS, NDI, and increased ROM across all groups post-treatment (p < 0.001). While Groups A and B demonstrated superior outcomes compared to Group C, differences between Groups A and B were not statistically significant (p > 0.05). For VAS and NDI, Cohen-d between Groups A and B was 0.31 and 0.31, and for ROM, Cohen-d was 0.37, 0.16, 0.07, 0.29, 0.36, and 0.53 for flexion, extension, right rotation, left rotation, right bending, and left bending, respectively. Furthermore, all groups experienced a significant decrease in JPE, with Groups A and B showing greater improvement than Group C (p < 0.01). Group B exhibited significantly greater improvement in reducing JPE related to specific motions compared to Group A (p < 0.05). CONCLUSION: Cervico-thoracic junction mobilization and the Autogenic muscle energy technique offer enhanced management for mechanical neck pain by improving pain, function, ROM, and cervical proprioception.

Role of extracellular LncRNA-SNHG14/miRNA-3940-5p/NAP12 mRNA in colorectal cancer.

BACKGROUND: We aim to identify and analyze the expression of dyregulated RNAs in colorectal cancer (CRC). METHODS: We selected a panel of RNAs specific to CRC composed of Nucleosome Assembly Protein 1 Like 2 (NAP1L2) mRNA, LNCRNA SNHG14 small nucleolar RNA host gene 14 (LNCRNA SNHG14) and homo sapiens microRNA-3940-5p(hsa-miRNA-3940-5p) from genetic and epigenetic databases. Validation of the chosen RNAs was achieved by real time quantitative PCR in sera of patients with CRC, versus controls groups (benign lesions and healthy individual). RESULTS: We found that LLNCRNA SNHG14, hsa-miRNA-3940-5p and NAP1L2 mRNA had an excellent performance characteristics and more superior than CEA, and CA19.9 for differentiating CRC from controls. Combined expression of lncRNA SNHG14- hsa-miR-3940-5p and NAP1L2 mRNA had reached 100% sensitivity with accuracy 93%. Interestingly, serum hsa-miRNA-3940-5p could be an independent prognostic factor in CRC. CONCLUSION: The extracellular lncRNA SNHG14- hsa-miR-3940-5p - NAP1L2 mRNA may aid in CRC management.KEY MESSAGESThe extracellular RNAs provide a potential class of noninvasive biomarkers with high specificity, accuracy and stability for detection of CRC.We used insilico data analysis followed by qPCR for detection of differential NAP1L2 gene expression with the selected epigenetic regulators.Our data presented interesting biomarker panel (NAP1L2 gene, lncRNA-SNHG14 and hsa-miR-3940-5p) that may be potential for CRC diagnosis and prognosis.

Clinical significance of serum DRAM1 mRNA, ARSA mRNA, hsa-miR-2053 and lncRNA-RP1-86D1.3 axis expression in malignant pleural mesothelioma.

AIM AND BACKGROUND: Malignant pleural mesothelioma (MPM) is a lethal cancer mainly caused by chronic exposure of asbestos. In this pilot study, we aimed to assess the expression of serum RNA-based biomarker panel exploring their clinical utility as diagnostic and prognostic biomarkers for MPM. METHODS: We have selected an MPM-specific RNA-based biomarker panel through bioinformatics analysis based on the integration of DNA damage regulated autophagy modulator 1 (DRAM1) and arylsulfatase A ( ARSA) gene expression with their epigenetic regulators microRNA ( miR-2053) and long noncoding RNA ( lncRNA-RP1-86D1.3). Then, quantitative real-time polymerase chain reaction (qPCR) validation in sera of 60 MPM patients, 20 chronic asbestos exposure patients, and 20 healthy volunteers was done. Lastly, the prognostic power of the selected panel was assessed. RESULTS: The expression of serum DRAM1 messenger RNA (mRNA), ARSA mRNA, hsa-miR-2053 and lncRNA-RP1-86D1.3 were positive in 78.3%, 90%, 85%, and 83.3% of MPM patients, respectively. The RNA-based biomarker panel was able to discriminate between MPM patients and controls with high accuracy and their combined sensitivity reached 100% for the diagnosis of MPM. Kaplan-Meier analysis showed that hsa-miR-2053 is an independent prognostic factor of MPM. CONCLUSION: Our preliminary data revealed that the chosen RNAs play an important role in driving MPM development and progression.

circRNAs (hsa_circ_00156, hsa_circ _000224, and hsa_circ _000520) are novel potential biomarkers in hepatocellular carcinoma.

Circular RNAs (circRNAs) are a newly validated type of noncoding RNAs recently found to be deregulated in several human cancers. More accurate and specific noninvasive biomarkers are strongly needed for better diagnosis and prognosis of hepatocellular carcinoma (HCC). We performed a bioinformatics analysis to retrieve a novel panel of circRNAs potentially relevant to HCC. We examined their expression in the sera of 68 patients with HCC, 60 patients with chronic hepatitis C, and 36 healthy controls using quantitative polymerase chain reaction. We examined the performance characteristics of the selected circRNA biomarker panel in comparison with alpha-fetoprotein (AFP). In addition, we performed a survival analysis to correlate between their expression levels and patient survival. The circRNAs hsa_circ _00224 and hsa_circ _00520 showed a strong biomarker potential with relatively high sensitivities and specificities compared with AFP. The combined panel including the three circRNAs showed superior performance characteristics relative to those of AFP. The median follow-up period was 26 months. hsa_circ_00520 expression has been shown to be associated with relapse-free survival (P < 0.005). circRNAs hsa_circ_00156, hsa_circ_000224, and hsa_circ_000520 are novel potential biomarkers of high sensitivity and specificity, which could potentially be used in the diagnosis of HCC.

Identification of Novel Molecular Network Expression in Acute Myocardial Infarction.

BACKGROUND: In the current study, we aimed to analyze the hypothesis that human myocardial-specific extracellular RNAs expression could be used for acute myocardial injury(AMI) diagnosis. METHODOLOGY: We used bioinformatics' analysis to identify RNAs linked to ubiquitin system and specific to AMI, named, (lncRNA-RP11-175K6.1), (LOC101927740), microRNA-106b-5p (miR-106b-5p) and Anaphase, promoting complex 11 (ANapc11mRNA). We measured the serum expression of the chosen RNAs in 69 individuals with acute coronary syndromes, 31 individuals with angina pectoris without MI and non-cardiac chest pain and 31 healthy control individuals by real-time reverse-transcription PCR. RESULTS: Our study revealed a significant decrease in both lncRNA-RP11-175K6.1 and ANapc11mRNA expression of in the sera samples of AMI patients compared to that of the two control groups alongside with significant upregulation of miR-106b-5p. CONCLUSION: Of note, the investigated serum RNAs decrease the false discovery rate of AMI to 3.2%.

Computational prediction of vaccine potential epitopes and 3-dimensional structure of XAGE-1b for non-small cell lung cancer immunotherapy.

BACKGROUND: XAGE-1b is shown to be overexpressed in lung adenocarcinoma and to be a strong immunogenic antigen among non-small cell lung cancer (NSCLC) patients. However, 3D structure of XAGE-1b is not available and its confirmation has not been solved yet. METHODS: Multiple sequence alignment was run to select the most reliable templates. Homology modeling technique was performed using computer-based tool to generate 3-dimensional structure models, eight models were generated and assessed on basis of local and global quality. Immune Epitope Database (IEDB) tools were then used to determine potential B-Cell epitopes while NetMHCpan algorithms were used to enhance the determination for potential epitopes of both Cytotoxic T-lymphocytes and T-helper cells. RESULTS: Computational prediction was performed for B-Cell epitopes, prediction results generated; 3 linear epitopes where XAGE-1b (13-21) possessed the best score of 0.67, 5 discontinuous epitopes where XAGE-1b (40-52) possessed the best score of 0.67 based on the predicted model of the finest quality. For a potential vaccine design, computational prediction yielded potential Human Leukocyte Antigen (HLA) class I epitopes including HLA-B*08:01-restricted XAGE-1b (3-11) epitope which was the best with 0.2 percentile rank. Regarding HLA Class II epitopes, HLA-DRB1*12:01-restricted XAGE-1b (25-33) was the most antigenic epitope with 5.91 IC50 value. IC50 values were compared with experimental values and population coverage percentages of epitopes were computed. CONCLUSIONS: This study predicted a model of XAGE-1b tertiary structure which could explain its antigenic function and facilitate usage of predicted peptides for experimental validation towards designing immunotherapies against NSCLC.
