human interferon β (inf-β) is a member of cytokines family which different studies have shown its immunomodulatory and antiviral activities. in this study an expression vector was designed and constructed for expression of human inf-β-1b either in shake flasks and bench top bioreactor. the designed vector was constructed based upon pet-25b(+) with t7 promoter. recombinant human beta interferon ...

Researchers treated seed technology and crop yield as exogenous, thereby generating bias estimates. In practice, increases it’s stimulated by social capital other factors. This paper develops a choice model of maize-seed exogenously, then tested corrected for causality. A multistage sampling procedure was adopted using seven Agricultural Development Programme zones drawn from purposively select...

background: approximately 180 mutations have been described in β-thalassemia worldwide with specific spectrum in each ethnic population. this study determines the spectrum and the frequency of β-thalassemia mutations in patients with β-thalassemia trait and sickle cell-β-thalassemia.   methods: fifteen compound heterozygous sickle cell thalassemia (sct) and 23 β-thalassemia trait patients were ...

The production of β-lactamase enzymes is the main mechanism of resistance to β-lactam antibiotics in gramnegative bacilli. Therefore, it is important to identify the β-lactamases-producing bacteria for the treatment of caused infections. This article aimed to review the recent literature and guidelines regarding phenotypic detection of β-lactamases in common gram-negative bacilli in clinical sa...

thermodynamic study on the interaction of β-cd with poly ethylene oxide and poly acrylic acid was performed by isothermal titration calorimetry at 298k. when β-cd is added to the interpolymer complex, competition is created between host-guest and hydrogen bond. enthalpy of interaction between the β-cd and interpolymer complex was calculated using the extended solvation theory. p=1 shows that wi...

Purpose: This study aimed to identify factors influencing the health-related quality of life elderly men in partial medically underserved rural areas. Methods: The subjects included 182 aged 65 or older living jurisdictions Health Care Centers G, I, and J Myeon, which were areas Gongju City, South Korea. Data collected on October 31 November 1, 2020, analyzed with descriptive statistics, t-test...

fecl3.6h2o was used as an efficient catalyst for the synthesis of highly functionalized piperidines via a one-pot five-component reaction of aromatic amines, aromatic aldehydes and β-keto esters in etoh at room temperature. the remarkable advantages offered by this method are good yields, simple procedure, short reaction times, no need to column chromatography and easy work-up. the structures o...

background :    pseudomonas aeruginosa is a severe challenge for antimicrobial therapy, because of chromosomal mutations or exhibition of intrinsic resistance to various antimicrobial agents such as most β-lactams. we undertook this study to evaluate the existence of sme, aim and vim metallo-beta lactamases encoding genes among p. aeruginosa strains isolated from icu patients in al-zahra hospit...
