    Abstract The safety, inherent immunogenicity, stability, and low-cost production of bacteriophages make them an ideal platform for vaccine development. Most vaccination strategies against COVID-19 have targeted the spike protein of SARS-CoV-2 to generate neutralizing antibodies. P1, a truncated RBD-derived spike protein, has been shown to induce virus-neutralizing antibodies in preclinical studies. In this study, we first investigated whether recombinant phages displaying P1 on the M13 major protein could immunize mice against COVID-19, and second, whether inoculation with 50 µg of purified P1 in addition to the recombinant phages would stimulate the immune systems of the animals. The results showed that the mice that received recombinant phages were immunized against the phage particles, but did not have anti-P1 IgG. In contrast, compared with the negative control, the group that received a combination of P1 protein and recombinant phage was immunized against the P1 protein. In both groups, CD4

    Abstract Background: Spinal cord injury (SCI) due to lack of restoration of damaged neuronal cells is associated with sensorimotor impairment. This study was focused on using the human placental mesenchymal stem cells- exosome (HPMSCs- Exosomes) in an animal model of severe SCI under myelogram procedure.
    Methods and results: Intrathecal injection of exosomes was performed in the acute phase of SCI in female rats. The improved functional recovery of the animals was followed for 6 weeks in control (saline, n = 6) and HPMSCs- EXO (HPMSCs-Exosomes, n = 6) groups. Pathological changes and glial scar size were evaluated. The Immunohistochemistry (IHC) of GFAP and NF200 factors as well as the apoptosis assay was investigated in the tissue samples from the injury site. The results demonstrated that HPMSCs-exosomes can improve motor function by attenuating apoptosis of neurons at the injury site, decreasing GFAP expression and increasing NF200 in the HPMSCs-EXO group. Also, HPMSCs-exosomes by preventing the formation of cavities causes preservation of tissue in SCI rats.
    Conclusions: These findings demonstrate the effectiveness of HPMSC-Exosomes as a therapeutic method to improve functional recovery, reduce pathological changes associated with injury, and prevent chronicity after SCI. The neuroprotective and anti-apoptotic potential of HPMSCs- Exosomes may be a promising therapeutic approach for SCI. Another result was the importance of intrathecal injection of exosomes in the acute phase, which accelerated the healing process. Furthermore, the myelogram can be a feasible and suitable method to confirm the accuracy of intrathecal injection and examine the subarachnoid space in the laboratory animals.

    Abstract Among the main structural protein of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), nucleocapsid phosphoprotein (NP) exhibits high immunogenicity and is the most abundant viral protein produced and shed during infection. Detection of antibodies against NP may help assess the number of individuals exposed to SARS-COV-2 or vaccinated against it. Based on these findings and other structural and antigenic evaluations, we designed a recombinant truncated fusion NP-based protein for application in an immunoassay for detecting immunoglobulins in patients who have recovered from COVID-19. In this research, we aligned the NPs from SARS-CoV and SARS-CoV-2 and selected highly antigenic parts of the SARS-CoV-2 sequences based on in-silico studies. The protein was expressed under optimum conditions in the bacterial host BL21 and purified by nickel immobilized metal affinity chromatography. Moreover, the purity level was assessed by SDS-PAGE and Western blotting whereas the folding of the protein was evaluated by circular dichroism. Ultimately, we used the purified recombinant protein in ELISA development in which 42 samples from convalescent patients were compared with 20 samples of the past 2019 patients who had attended laboratories for various clinical check-ups. The sensitivity and specificity were determined as 71% and 90%, respectively, in the optimum cut-off point measured by the receiver operating characteristic curve.

    Abstract Objectives: The spike protein has been reported as one of the most critical targets for vaccine design strategies against the SARS-CoV-2 infection. Hence, we have designed, produced, and evaluated the potential use of three truncated recombinant proteins derived from spike protein as vaccine candidates capable of neutralizing SARS-CoV-2 virus.
    Methods: In silico tools were used to design spike-based subunit recombinant proteins (RBD (P
    Results: The antibodies that existed in the serum of COVID-19 patients were identified by designed proteins. The anti-spike antibody titer was increased in the animals injected with recombinant proteins. The VNT results revealed that the produced antibodies could neutralize the cultured live virus.
    Conclusion: Truncated subunit vaccines could also be considered as robust tools for effective vaccination against COVID-19. Using a combination of in silico, in vitro, and in vivo experiments, it was shown that the injection of spike-based truncated recombinant proteins could stimulate long-lasting and neutralizing antibody responses.

    Abstract Background: Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder. This study aimed to investigate whether disturbances in amino acid metabolism and fatty acid oxidation existed in neonates with CH compared to healthy neonates.
    Methods: In this case-control study, we evaluated the metabolomics of neonates with newly diagnosed CH and healthy neonates. Forty-three metabolites, including 13 amino acids and 30 acylcarnitines, were investigated.
    Results: Two hundred neonates with CH and 209 healthy children were enrolled. The mean age of males and females was 4.8 ± 2.4 and 5.52 ± 3.2 days in the case group and 5.1 ± 2.6 and 4.7 ± 3.6 days in the control group, respectively. Of the metabolites, 34 were significantly different between the two groups. Five amino acids and four acylcarnitines did not differ significantly between groups.
    Conclusion: These findings pave the way for a better understanding of the relationship between alterations and the clinical manifestation of CH, which has the potential for identifying novel therapeutics.

    Results: A truncated MMP-9 is the major epitope peptide that can trigger the immune system to scavenge for a specific and reactive antibody against the native MMP-9. The MMP-9 native protein is purified from the supernatant of the HCT 116 cell line and the commercially available, full-length MMP-9. The cut-off value was estimated at 30 μg/mL. QC results indicated that the specificity was 80%, sensitivity was 96.7%, accuracy was 91%, and precision was 91.66%. The area under curve was 0.827 (
    Conclusions: The antibody against the synthetic epitope peptide can detect the native MMP-9. Native MMP-9 is considered the main biomarker in an immunoassay POCT and is used to diagnose dry eye disease (DED). In accordance with QC results, MMP-9 point of care test can be utilized for screening patients suffering from DED.

    Abstract Dry eye syndrome (DES) and tear dysfunction are multifactorial conditions affecting meibomian glands, lacrimal glands, and ocular surface. This ocular disorder can cause eye irritation, irregular cornea, corneal barrier disruption, and blurred vision. Uncontrolled increase in matrix metalloproteinase-9 (MMP-9) level and activity has been detected in the tears and ocular surface in the patients with DES, which has been proved to be related to disruption of tight junctions in apical corneal epithelium associated with severe signs of DES. These uncontrolled activities of MMP-9 lead to desquamation of ocular surface epithelia. Therefore, this review study was conducted to summarize the evidence regarding MMP-9 contribution in DES, and inhibition of MMP-9, as a therapeutic target for treatment of DES. For this purpose, herein, the related studies designed novel pharmaceutical compounds for direct and indirect inhibition of MMP-9 as treatment approaches for DES were reviewed. These compounds were designed to improve corneal barrier function, reduce inflammation on ocular surface, and restore tear production.

    Abstract Neonatal hypothyroidism is a deficiency of thyroid hormones at birth that can cause lifelong mental and physical disorders in humans. Lack of timely detection could lead to irreversible damage by neonatal hypothyroidism. However, it could be managed quickly and efficiently via timely diagnosis. The screening programs rely on immunoassays to diagnose neonatal hypothyroidism in most countries. This method is time-consuming, needs laboratory equipment, and should be performed by trained and skilled technicians. Given these circumstances, the ELISA method is not a preferable method for the diagnosing of neonatal hypothyroidism. However, it can be used as a confirmatory method in infants with suspected and unknown neonatal hypothyroidism. In the present study, the homemade SR95-1, SR95-2, and SR95-3 anti-β-TSH polyclonal and the commercially available monoclonal antibodies were used to detect β-TSH in a rapid assay kit design hypothyroidism screening. To design the kit, the different combinations of the antibodies were used to establish a sandwich immune-chromatography method. The designed rapid neonatal hypothyroidism tests were used to measure neonatal β-TSH in 100 dry blood samples. This study showed that the best antibody pair in terms of sensitivity is the SR95-1 antibody as capture antibody and the SR95-2 as a conjugated antibody. Using 100 clinical samples, the designed assay was shown to have 94% sensitivity, 83% specificity, and 94% accuracy. The results showed that polyclonal antibodies (SR95-1 as capture) and SR95-2 (as detector) antibodies can detect the reference range of β-TSH in dried blood samples and can be used in the screening of neonatal hypothyroidism.
