objective(s) human umbilical cord blood (hucb) is now considered as a valuable source for stem cell–based therapies. previous studies showed that intravascular injection of the hucb significantly improves neurological functional recovery in a rat model of intracerebral hemorrhage (ich). in the present study, we hypothesize transplanted hucb derived mononuclear cells (uc-mcs) can decrease injure...
results of 45 patients, 4 (8.9% [95% ci: 4.4-15.6]) had detectable genomic hcv-rna in their pbmc specimens. hcv genotypes were determined in the pbmcs of these subjects showed that 2 (50.0%) subjects with occult hcv infection had hcv subtype 3a, and 2 (50.0%) had hcv subtype 1b. conclusions this study found that 8.9 % of the iranian candidates for liver transplant with cryptogenic cirrhosis had...
Introduction: Mammalian cells culture is an important method for producing recombinant proteins, monoclonal antibody, and hormones application. One of the common methods in the monocyte isolation is using flask adherent cell culture in RPMI-1640 medium. We aimed, in this study, cell culture medium using dextrose 5% with autologous plasma to produce inexpensive medium for isolation of monocytes....
angiocardiography is an x-ray examination of the blood vessels or chambers of the heart. cardiologists and staff members applying this procedure are exposed to high levels of scattered radiation. in our previous study the incidence of unstable chromosomal aberrations and cytokinesis-blocked micronuclei were found to be significantly higher in exposed individuals than the age and sex matched con...
Electrochemotherapy is an antitumor treatment that utilizes locally delivered electric pulses to increase the effectiveness of chemotherapeutic drugs in cells and tissues. Electric pulses permeabilize tumor cells to allow nonpermeant drugs such as bleomycin to enter the cells. Although preclinical data indicate that immune responsiveness of the organism is important for obtaining cures of the t...
patients and methods in this cross-sectional study, peripheral mononuclear cells (pbmcs) were isolated from peripheral blood of 29 patients with newly diagnosed pulmonary tb and 19 patients with positive tuberculin skin test. the pbmcs were activated with ppd for 72 hours. activated cells were harvested, rna was extracted and cdna was synthesized. a real-time taqman method was designed and opti...
At 4 to 6 weeks after intravenous infection with 2 X 10(4) CFU of dispersed Mycobacterium bovis bacilli (BCG), C3H/HeNCrIBR and C57BL/6NCrIBR mice exhibited a strong reaction to purified protein derivatives, as evaluated by the increase in footpad swelling at both 24 and 48 h after local antigenic challenge. However, histological studies of the footpad skin demonstrated a prominent perivascular...
Haemophilus ducreyi elicits a cutaneous infiltrate of CD4 cells during experimental human infection.
Human subjects were experimentally infected with Haemophilus ducreyi for up to 2 weeks. Bacterial suspensions were delivered into the epidermis and dermis through puncture wounds made by an allergy-testing device. Subjects developed papular lesions that evolved into pustules resembling natural disease. Some papular lesions resolved spontaneously, indicating that host responses may clear infecti...
To determine whether polymorphonuclear leukocytes (PMN) modulate the production of tissue factor (TF) by monocytes, PBMC were incubated with increasing concentrations of PMN. PMN did not express any procoagulant activity. After 20-h cocultures, PMN enhanced or inhibited the TF production of PBMC, and this effect depended on the PMN/PBMC ratio. When the ratio increased from 1/1000 to 1/5, withou...
