There is no doubt that grammar is a basic and indispensable element in language. However, it is still under debate that whether grammar should be taught in class. Although Krashen(1981) argues that grammar instruction has little benefit on L2(second language) acquisition(as cited in Ellis, 2006), many educators still insist that grammar should be taught, especially for beginners and intermediate level students. Since students' proficiencies are various, a large number of instructors believe that teaching grammar is necessary and important for students to acquire the ability of listening, speaking, reading, and writing in their second language. Therefore, according to previous research studies and teaching practices, the following questions will be addressed: Why should grammar be taught in class, how to teach grammar and are there any strategies to improve the quality of grammar instruction, especially for non-native-speaking students at basic or intermediate level. Last but not least, are there any educational implications when teaching grammar in practice?

The importance of understanding the protein folding pathway and intermediates is well recognized on the basis of extensive studies of protein folding in vitro and in vivo. Creatine kinase (CK) is a typical model for studying unfolding and refolding of proteins due to several interesting properties. Recent studies on the folding of CK show that its partially folded monomeric intermediate is present kinetically and is stable at equilibrium. The present paper contains 33 references as a mini review to characterize the properties of CK from studies on the CK folding pathway. Characterization of these intermediates is an essential step toward understanding the mechanism of protein folding. Some well determined schemes are suggested as protein folding models.

An important anticancer nucleosides intermediate (2R,3S,4S,5R)-2-(acetoxymethyl)-5-(3-bromo-5-(methoxycar-bonyl)-1H-1,2,4-triazol-1-yl)tetrahydrofuran-3,4-diyl diacetate was synthesized by directly coupling the bromotriazole with the protected ribose sugar, and have given the corresponding product in moderate yield. Its structure and conformation were confirmed by single crystal X-ray diffraction.

Introduction: Routine PSA screening for prostate cancer (PCa) has increased the detection of intermediate-risk, localized disease. Conventional treatments for localized PCa include surgery, brachytherapy, cryotherapy or external beam radiotherapy (EBRT). However, for intermediate risk patients, rates of recurrence are moderately high and a multi-modal treatment approach for these patients may be necessary. We treated patients with a combination of cryotherapy and low dose EBRT to assess the safety and feasibility of this combinatory approach as well as to evaluate early oncological outcomes. Case Presentation: Men with intermediate risk (PSA = 10-20 ng/ml and/or Gleason = 7 and/or clinical T2b) localized PCa were prospectively enrolled in this study. Patients underwent cryotherapy and then 39 Gy EBRT 4-6 weeks after surgery. After completing EBRT, the men were followed every 3 months for 2 years. Adverse events, PSA, urinary and erectile function were assessed during each follow-up. Three patients completed the study. Preoperative PSA ranged from 3.5 to 7.9 ng/ml. There were no intraoperative complications and the treatment was well tolerated. Following cryotherapy and EBRT, all patients were pad-free within 6 months and remained continent for the duration of the study. Bother index remained stable throughout the study for all patients. No urethral strictures or rectal toxicities were observed. PSA remained undetectable for all patients. Conclusions: In this prospective study, cryotherapy combined with low dose EBRT was a safe approach for the treatment of intermediate-risk, localized PCa. Early oncological outcomes appeared to be favorable with all patients having undetectable PSA during the 2-year follow-up period. Further studies are warranted to confirm these preliminary results.
