background: beta thalassemia gene mutations are among common mutations in southwest iran. however, hemoglobin e (hb e) and hb e/β⁰ thalassemia account for a small number of hemoglobinopathies in iran. this is the first study to directly address the existence of hb e and consequently hb e/β⁰ thalassemia in southwest iran. methods: this retrospective study discovered seven cases of hb e/β⁰ thalas...

in order to reduce the costs associated with poly-β-hydroxybutyrate production, growth and poly-β-hydroxybutyrate production of ralstonia eutropha were studied in batch culture on different carbon sources. experiments were designed and conducted to not only lower the cost of poly-β-hydroxybutyrate production by using inexpensive substrates, but also to increase poly-β-hydroxybutyrate production...

We continue the study, initiated in (J. Eur. Math. Soc. (JEMS) 20 (2018) 199–257), of localization transition a lattice free field ϕ=(ϕ(x))x∈Zd, d≥3, presence quenched disordered substrate. The substrate affects interface at spatial sites which height is close to zero. This corresponds Hamiltonian ∑x∈Zd(βωx+h)δx, where δx= 1[−1,1](ϕ(x)), and (ωx)x∈Zd an i.i.d. centered field. A takes place when...

conclusions this study showed that multiple β-lactamases can be produced in burn isolates. this suggests that use of cephalosporins and carbapenems should be restricted in burn isolates to minimize the development and spread of these multidrug resistant pathogens. results there was 99% resistance to carbenicillin, and ticarcillin, 98% to cotrimoxazole, 96% to ciprofloxacin, and aztreonam, 95% t...

Objective: Given the importance of COVID-19 consequences and students’ health, this study aimed to predict fear based on spiritual well-being self-efficacy among Iranian university students by focusing mediating role mindfulness. Methods: This was a descriptive correlational study. An online sampling method used, sample included 396 in Tehran City, Iran. Mindful Attention Awareness Scale (MAAS)...

Fundamental properties of neutrinos are investigated by studying double beta decays ( ββ -decays), while atro-neutrino nucleo-syntheses and astro-neutrino productions inverse (inverse β -decays) induced astro-neutrinos. Neutrino nuclear responses for these id="mi...

background :   ampc β-lactamases are important cephalosporinases chromosomally encoded in many of enterobacteriaceae and a few other organisms where they mediate resistance to cephalothin, cefazolin, cefoxitin and penicillins. the six different families of plasmid-mediated ampc β-lactamases have been described, but no phenotypic test can discriminate among them. ampc multiplex pcr has been succ...

abstract         background and objective: microalgae are a group of algae that produce biochemical products consisting of a wide range of carbohydrates, lipids and proteins that are commercially valuable. interest in microalgal cultivation is currently blossoming globally. species of dunaliella are found in freshwater, euryhaline habitats of all continents, oceans including the dead sea and ev...

the purpose of this study was to produce oil in water nano-emulsion by ultrasonication, and investigate the influence of inulin and β-cyclodextrin on the prosperities of nano-emulsion and morphology of spray dried microcapsules. the results showed that emulsion droplet size in samples containing β-cyclodextrin (8.28±0.11 nm) was less than inulin samples (97.12±4.2 nm). considering sem photos, β...
