We have isolated carcinoembryonic antigen (CEA)-related antigens from meconium and compared them with those in adult feces. Two CEA-related antigens were detected in meconium [nonspecific cross-reacting antigen 2 (NCA-2) and meconium nonspecific cross-reacting antigen] while four CEA-related antigens were found in adult feces [normal fecal antigen 1, normal fecal antigen 2 (NFA-2), normal fecal...

To explore the clinical characteristics of hepatitis in pregnant women with chronic B virus infection and efficacy telbivudine treatment is main objective. In this study, 136 diagnosed our hospital from March 2017 to December 2018 were selected as research objects. According whether patients had episodes, they divided into 96 cases seizure group 40 non-seizure group. The two groups compared. di...

This study aimed characterize and compare SARS-CoV-2 SARS-CoV major viral proteins predict antigen proteasomal cleavage patterns, MHC class I processing presentati...

background : echinococcosis or hydatidosis is a chronic, zoonotic worldwide infection caused by the larval stage of the dog taeniid tapeworm echinococcus granulosus. vaccination has been considered as one of the ways to prevent of hy-datidosis in recent decades. the aim of this study was to construct a pcdna3.1 eukaryotic expression vector contain-ing the subunit 8-kda antigen b (hyd1) of e. gr...

in addition to ultrasonographic monitoring of folliculogenesis, urinary luteinizing hormone testing, luteal phase endometrial biopsy, serum antiphospholipid antibodies, etc., immunologic tests are recently being used to evaluate reproductive disorders. in this study, sharing of hla-a, b, c and dr antigens and the presence of antipaternal cytotoxic antibody (apca) was assessed using microcytotox...

background: breast cancer is the most common cancer in women. prostate‑specifc antigen  (psa) is a marker of prostate gland malignancy, which has been considered in cases with breast cancer in recent years. the goal of this study was to determine total and free psa levels in cases with malignant and benign breast lesions. methods:   in  this case–control study, ninety women with histological pr...

apoptosis, or active cell death, is a specific mode of cell death, which is characterized by morphological changes such as chromatin condensation, fragmentation of the nucleus, cytoplasmic retraction and appearance of apoptotic bodies' containing apparently intact organelles. apoptosis occurs in physiological conditions as a regulatory mechanism of tissue growth, where cell proliferation is bal...

chlamydia trachomatis is an obligate intracellular bacterium which causes a wide variety of human infections such as ocular, urogenital and respiratory infections. genital infections of women, espe-cially when repeated, give rise to many complications such as ectopic pregnancy, miscarriage and in fertility. since chlamydial infections are usually asymptomatic, they progress unnoticed and produc...

background: cystic echinococcosis (ce), also known as echinococcosis/hydatidosis, is one of the most important parasitic diseases in the world. it enhances both humoral and cellular (th1 and th2) responses in infected host. different antigens of the worm may favor the th1 or th2 immune responses in ce patients. objective: to evaluate the humoral and cellular immune responses of balb/c mice agai...
