Objective(s) Comparison of prooxidant-antioxidant balance (PAB) assay with crocin assay. Materials and Methods Twenty eight serum samples were chosen, PAB and the total antioxidant capacity were measured by PAB assay and crocin, respectively, and the correlation of both assays, along with their correlation with other clinical and biochemical parameters, were determined. Results A significa...

results a significant higher serum pab value was observed in shift working and daytime nurses (152.28 ± 43.64 hk) in comparison to the control group (63.64 ± 34.41 hk index), p value = 0.001. in day time nurses, also serum pab between male (119.09 ± 47.14 hk) and female (162.53 ± 37.02 hk) in nursing workers was significant, p value = 0.005. in the night shift working nurses, there was also a s...

ilex spinigera (aquifoliaceae) plant is an evergreen tree or shrub with thick glossy dark green leaves and red fruits. this plant has medicinal properties and has been used traditionally in northern iran for malaria treatment. the aim of this work is to evaluate the antioxidative activities and the inhibitory effect of i.spinigera on the oxidation of dna. we have found no reports about the popu...

Antibody-based immunotherapy has been effectively used for tumor treatment. However, to date, only a few tumor-associated antigens (TAAs) or therapeutic targets have been identified. Identification of more immunogenic antigens is essential for improvements in multiple myeloma (MM) diagnosis and therapy. In this study, we synthesized a polyclonal antibody (PAb) by immunizing rabbits with whole h...

Ovarian cancer has the highest mortality rate among gynecological cancers; the most effective therapy for this cancer is a combination of radiation treatment and chemotherapy. However, radiation resistance is the leading factor associated with treatment failure. The present study aimed to investigate pseudolaric acid B (PAB) as a potential radiosensitizer for the treatment of ovarian cancer. Th...

A rapid and simple immuno-chromatographic assay was developed to detect aflatoxin B1 (AFB1). The assay was based on a modified competitive binding format using colloidal gold and polyclonal antibody (Pab) conjugates. The anti-AFB1 Pab was immobilized to a defined detection zone on a porous nitrocellulose membrane and colloidal gold particles were conjugated to AFB1-BSA which served as a detecti...

OBJECTIVE PAB induced various cancer cell apoptosis, cell cycle arrest and senescence. But in cell line murine fibrosarcoma L929, PAB did not induce apoptosis, but autophagy, therefore it was thought by us as a good model to research the relationship of cell cycle arrest, autophagy and senescence bypass apoptosis. METHODS Inhibitory ratio was assessed by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphe...

Aim. This study was aimed at evaluating prooxidant-antioxidant balance (PAB) in patients with systemic lupus erythematosus (SLE) and its relationship with laboratory findings and clinical manifestations. Methods. In this case-control study, 60 patients with SLE and 60 healthy individuals were enrolled. The blood samples were collected and their sera were separated. Subsequently, the prooxidant-...

Objective. Using a novel assay termed prooxidant-antioxidant balance (PAB) assay to determine prooxidant-antioxidant balance in umbilical cord blood of infants with meconium stained of amniotic fluid (MSAF). Passage of meconium in amniotic fluid is associated with increase of neonatal mortality and morbidity. This complication occurs in about 15% of infants and is more widespread in postterm ne...
