Myofibril-bound creatine kinase EC 2.7.3.2 (CK), a key enzyme of muscle energy metabolism, has been selected for studies of conformational changes that underlie the cellular control of enzyme activity. For fluorescence spectroscopy measurements, the CK molecule was double-labeled with IAF (5-iodoacetamidofluorescein) and ErITC (erythrosin 5'-isothiocyanate). Measurement of fluorescence resonanc...

Studies have mainly focused on strategies to motivate teachers or the student-teacher motivation relationships rather than teacher demotivation in the English as a foreign language (EFL) teaching process, whereas no data have been found on the factors that cause teacher demotivation in the Turkish EFL teaching contexts at the elementary education level. Thus, this study aims to investigate the ...

The development of an organism depends on individual cells receiving and executing their specific fates, although how this process is regulated remains largely unknown. Here, we identify a mechanism by which a specific cell fate, apoptosis, is determined through the cooperative efforts of Hox and E2F proteins. E2F transcription factors are critical, conserved regulators of the cell cycle and ap...

The issue of natural order in acquiring some morphemes in English has been a controversial one in psycholinguistics and applied linguistics. This article seeks to test Krashen’s Natural Order Hypothesis employing the Competition Model among two age groups of pre-adolescent and adult age in an EFL setting. Research on this issue has been mostly conducted in ESL settings and the results have been...

The acronyms of ENL, ESL, and EFL have been around for long enough as names of certain varieties of English depending on their locale and related circumstances of use. In their expanded form, they are known as ' ', ' ', and ' '. Far from being hypothetical varieties of the language, the three have their distinctive traits that are measurable along sociolinguistic and linguistic clines. On both ...

often given with prednisolone, would have been necessary. In pregnant women with West African (T. brucei gambiense) stage II disease, either melarsoprol or eflornithine can be used, but neither is effective for East African disease. Although efl ornithine can abort early pregnancies and cause disordered organogenesis (9), the severe encephalopathy associated with melarsoprol makes efl ornithine...

the present study was conducted to investigate how efl learners with distinct levels of emotional intelligence might benefit from critical thinking-based instruction and use different language learning strategies. a further concern of this study was to investigate the relationship among critical thinking, language learning strategy, and emotional intelligence of efl learners. to this end, 88 ef...

Phonological-based instruction, namely phonological awareness instruction (PA) and phonics instruction, has shown to be effective on early literacy skills among young children in western countries. Children who learn English as a foreign language (EFL) learn to read English differently from children in English-dominant societies. Effectiveness of the instruction in the EFL context is much less ...
