Article Abstract
Background: Graves' disease (GD) is one of the most common autoimmune thyroid diseases (AITDs) in humans, and thyrotropin receptor antibody (TRAb) is a characterized autoantibody in GD. The use of radioactive iodine therapy (RAI) for GD treatment is increasing.
Objectives: We studied the biological properties of TRAb and evaluated the effect of RAI therapy on TRAb in GD patients.
Methods: In total, 225 patients (22 onset GD patients without I therapy, 203 GD patients treated with I therapy) and 20 healthy individuals as normal controls were included in this study. Clinical assessments were performed, and we examined in vitro the biological properties of TRAb in the 22 onset GD patients and 20 controls as well as 84 GD patients with I therapy.
Results: Serum TRAb and thyroid peroxidase antibody (TPOAb) levels increased in the initial year of RAI treatment, and both antibodies decreased gradually after one year. After 5 years from radioiodine treatment, TRAb and TPOAb levels decreased in 88% and 65% of GD patients, respectively. The proportion of patients positive for thyroid-stimulatory antibody (TSAb) was significantly higher in the 7-12-month group, and thyroid-blocking antibody (TBAb) levels were elevated after one year in half of the patients who received I treatment.
Conclusions: Treatment of GD patients with radioiodine increased TPOAb and TRAb (their main biological properties were TSAbs) within the first year after therapy, and the main biological properties of elevated TRAb were TBAbs after 1 year.
Background/aims: Phenobarbital (PB), commonly used for epilepsy management, is associated with testicular dysfunction after prolonged use. This study aimed to evaluate the ameliorative effects of cranberry (CB) and vitamin C (Vit-C) on PB-induced reproductive toxicity in rats.
Methods: Forty male Wistar rats were divided into five groups.
Uniform, mesoporous copper(II) oxide nanospindles (CuO NSs) were synthesized via a method based on templated hydrothermal oxidation of copper in the presence of monodisperse poly(glycerol dimethacrylate--methacrylic acid) nanoparticles (poly(GDMA--MAA) NPs). Subsequent decoration of CuO NSs with a CaO nanoshell (CuO@CaO NSs) yielded a nanozyme capable of Cu(I)/Cu(II) redox cycling. Activation of the Cu(I)/Cu(II) cycle by exogenously generated HO from the CaO nanoshell significantly enhanced glutathione (GSH) depletion.
Histatin 5 (Hst5) is a 24-amino-acid peptide naturally present in human saliva that has been proposed as a potential antifungal therapeutic. However, Hst5 is susceptible to degradation by secreted aspartyl proteases (Saps) produced by Candida albicans, which could limit its efficacy as a therapeutic. To better understand the role of the lysine residues of Hst5 in proteolysis by C.

Comonomer defects can induce semicrystalline polymers to form unique crystalline structures (., defect crystals), which can greatly influence the materials' physical properties. However, the formation mechanism and structural evolution of defect polymer crystals are not yet well understood.
This study aims to evaluate the impact of formulation parameters on tannic acid-crosslinked gelatine (GelTA) films, intended as a mucoadhesive matrix for extended buccal drug delivery. GelTA films were prepared using the solvent evaporation technique and screened based on their mucoadhesive and dissolution characteristics. The formulation variables included the source of gelatine (bovine and fish), tannic acid concentration, pH of the film-forming solutions, and the type and concentration of plasticisers.
