In in tes t ina l mucosa of fed adult rats, cytochrome P-450 content and ac t i v i t y of benzpyrene hydroxyl ase and p-n i t roaniso le O-demethylase are highest in the upper small in test ine and progressively decrease toward the terminal ileum. Among the mucosal cell populations, mature v i l l ous t i p cel ls contain 6 to I0 times more cytochrome P-450 and drug-metabolizing ac t i v i t y...

The midgut environment of anopheline mosquitoes plays an important role in the development of the malaria parasite. Using genetic manipulation of anopheline mosquitoes to change the environment in the mosquito midgut may inhibit development of the malaria parasite, thus blocking malaria transmission. Here we generate transgenic Anopheles stephensi mosquitoes that express the C-type lectin CEL-I...

Various streptomyces strains [Streptomyces lividans 66, Streptomyces vinaceus, and Strepotmyces coelicolor A3 (2)] acquired the ability to utilize crystalline cellulose (Avicel) after transformation with a multicopy vector containing the cel-1 gene from Streptomyces reticuli. The expression level in these hosts was two to three times lower than in S. reticuli, indicating the absence of positive...

In chronic myelogenous (CML) and chronic eosinophilic leukemia (CEL), neoplastic cells spread via the circulation into various extramedullary organs. As E- and P-selectin constitute the starting point for the leucocyte adhesion/invasion cascade, and CEL and CML cells share many properties with normal granulocytes, we investigated the role of these selectins in CEL and CML cell expansion and org...

Chimeric antigen receptor (CAR) T cell therapies have demonstrated good clinical responses in populations that historically been difficult to treat; however, they are associated with potentially severe adverse events, including CRS and NEs. An economic model was created estimate total weighted costs of NEs for 2L treatment transplant-eligible relapsed/refractory large B-cell non-Hodgkin lymphom...

ackground: Knowing the human platelet antigens (HPA) and genes frequency in different populations is important not only for population studies but also for clinical transfusion practice. HPA genes frequency in Iran is not evaluated, so we investigated the HPA-2, HPA-3, and HPA-5 frequency and their polymorphism. Materials and Methods: DNA from 120 Iranians (99 Iranian blood donors and 21 patie...

The adsorption and separation properties of 3A zeolite are investigated by using Grand Canonical Monte Carlo (GCMC) simulation. To obtain the adsorption isotherms of water, methyl mercaptan, and methane on 3A zeolite, COMPASS Force Filed is used. The adsorption isotherms of the pure components and the ternary mixtures of water, methyl mercaptan, and methane on 3A zeolites are calculated. The Si...

Background: One of the most important causes of chronic liver disease is hepatitis C virus (HCV), which causes liver cirrhosis and hepatocellular carcinoma. To control the prevalence of the disease, knowledge and information in risk factor of HCV are required. The aim of this study was to compare the risk factors of infection between HCV patients with genotypes 1a and 3a. Methods: This is an o...
