PURPOSE: The environment comprises multiple optical signals that affect eye growth. We aimed to determine if the inhibitory effects of myopic defocus and bright light (BL) against myopia are additive in the presence of the myopia-genic hyperopic defo…
Due to their ability to induce immunological tolerance in the recipient, mesenchymal stromal cells (MSCs) have been utilized in the treatment of various hematological and immune- and inflammation-mediated diseases. The clinical application of MSCs im…
Silver and titanium dioxide nanoparticles (AgNPs and TiONPs) are highly useful, but they are also a significant reason for concern as they exert toxicity. The goal of research was to assess the role of three kinds of NPs in concentrations of 100 mg L…
The article presents the results of spectroscopic studies focused on a selected compound from the 1,3,4-thiadiazole group-2-(4-fluorophenylamino)-5-(2,4-dihydroxybenzeno)-1,3,4-thia-diazole (FABT)-in a micellar system formed by Triton X-100, a non-io…
BACKGROUND: A temporary loop ileostomy, which is used to decrease the risk of symptomatic anastamotic leakage after anterior resection and total mesorectal excision (TME), is traditionally closed without any mesh. However, as 44% of incisional site h…
Despite evidence that tripeptide glycyl-ʟ-histidyl-ʟ-lysine (GHK) is an endogenous antioxidant, its mechanism and importance are not fully understood. In the present study, the ability of GHK to reduce levels of reactive oxygen species (ROS) in Caco-…
BACKGROUND: B cells are key pathogenic effectors in multiple sclerosis (MS) and several therapies have been designed to restrain B cell abnormalities by directly targeting this lymphocyte population. OBJECTIVES: Moving from our data showing a Toll-li…
Hepatitis B virus (HBV) causes both acute and chronic hepatitis and infects large numbers of individuals worldwide. Unfortunately, prediction of typical clinical outcome is problematic and there is considerable variability in the frequency, duration…
We have preparedI-labeled cholera toxin B subunit (I-labeled CT-B, a specific activity of 98Ci/mmol) and found that it binds to rat IEC-6 and human Caco-2 intestinal epithelial cells with high affinity (K3.6 and 3.7nM, respectively). The binding of l…
The synthesis of thymosin-α, an acetylated 28 amino acid long therapeutic peptide, via conventional chemical methods is exceptionally challenging. The enzymatic coupling of unprotected peptide segments in water offers great potential for a more effic…
In cystic fibrosis (CF), deletion of phenylalanine 508 (F508del) in the cystic fibrosis transmembrane conductance regulator (CFTR) anion channel causes misfolding and premature degradation. Considering the numerous effects of the F508del mutation on…
The present study aimed to evaluate whether thymosin α1 (Tα1) increases survival rates through the improvement of immunofunction and inhibition of hepatocyte apoptosis in rats with acute liver failure (ALF). A total of 25 rats were randomly divided i…
BACKGROUND: Thymic atrophy was discovered in tumor-bearing mice in recent years. METHODS: Flow cytometry was carried out including Annexin V-FITC/PI double staining, PI staining, Terminal dUTP nick-end labeling, CD3-FITC/CD19-PE and CD8-FITC/CD4-PE d…
Thymosin α1 (Tα1) and bursin-like peptide (BLP) are both immunopotentiators. In order to investigate adjuvant of thymosin α1-bursin-like peptide (Tα1-BLP), we cloned the gene of Tα1-BLP and provided evidence that the gene of Tα1-BLP in a recombinant…
Tumor-targeted therapy is an attractive strategy for cancer treatment. Peptide hormone thymosin α1 (Tα1) has been used against several diseases, including cancer, but its activity is pleiotropic. Herein, we designed a fusion protein Tα1-iRGD by intro…
In the version of this article originally published, the amino acid sequence for Tα1 described in the Online Methods is incorrect. The sequence is described as "Ac-SDAAVDTSSEITTJDLKEKKEVVEEAEN-OH". It should be "Ac-SDAAVDTSSEITTKDLKEKKEVVEEAEN-OH". T…
BACKGROUND: Immune checkpoint blockade antibodies (imAbs), such as the anti Cytotoxic T Lymphocyte Antigen-4 (CTLA-4) ipilimumab (IPI) raised overall survival (OS) in metastatic melanoma (MM). Further, long-term OS is a crucial endpoint in MM. Thymos…
