    The essays in this issue explore how to enhance teaching and student learning in the classroom. Our first contributor argues that providing students the opportunity to write questions about course material is a fruitful way to address studentsā€™ reticence about asking questions during class and also may result in students performing better on testable material. Moreover, instructors benefit from having studentsā€™ questions because the written questions can also be used by the instructor to know better what students are and are not understanding about course material and alerts instructors to where they can further explain or clarify course material. Finally, our first contributor also suggests that students in interdisciplinary classrooms might especially benefit from writing their questions, while instructors of interdisciplinary courses may find the flexibility with using technology to address the written questions in ā€œreal timeā€ via the use of technology especially beneficial. In our second contribution, the author argues that pre-service teachersā€™ educational curriculum should address the academic literature that links poor musical-rhythmic tendencies with reading struggles for reading learners. The author also argues that the rhythm-reading connection is applicable to interdisciplinary educators because it asks those educators to reflect on possible connections between the body and the acquisition of skills that are usually considered purely intellectual. Our Impact book reviewers cover a varied set of interesting and important topics in this issue. One reviewer informs readers about a handbook on community psychology that prioritizes applied and interdisciplinary work; another reviewer details an authorā€™s synthesis of what contemporary archaeology has now come to understand about Maya civilizationā€™s resilient and complex society through time and within their varied mosaic of managed environments; a different reviewer delves into an authorā€™s exploration of how digital media platforms generate novel opportunities for sufferers of trauma to make sense of their experience, and our final reviewer details an authorā€™s accounting of the history, origins, and evolution of the Camp Fire Girls, one of Americaā€™s longest-serving girlsā€™ youth movements, its impact on girlsā€™ lives, and how the organization adapted to and resisted dominant ideologies about girls, culture, and race across time

    Binding of aminoglycoside antibiotics to helix 69 of 23S rRNA

    Aminoglycosides antibiotics negate dissociation and recycling of the bacterial ribosomeā€™s subunits by binding to Helix 69 (H69) of 23S rRNA. The differential binding of various aminoglycosides to the chemically synthesized terminal domains of the Escherichia coli and human H69 has been characterized using spectroscopy, calorimetry and NMR. The unmodified E. coli H69 hairpin exhibited a significantly higher affinity for neomycin B and tobramycin than for paromomycin (Kds = 0.3 Ā± 0.1, 0.2 Ā± 0.2 and 5.4 Ā± 1.1 ĀµM, respectively). The binding of streptomycin was too weak to assess. In contrast to the E. coli H69, the human 28S rRNA H69 had a considerable decrease in affinity for the antibiotics, an important validation of the bacterial target. The three conserved pseudouridine modifications (ĪØ1911, ĪØ1915, ĪØ1917) occurring in the loop of the E. coli H69 affected the dissociation constant, but not the stoichiometry for the binding of paromomycin (Kd = 2.6 Ā± 0.1 ĀµM). G1906 and G1921, observed by NMR spectrometry, figured predominantly in the aminoglycoside binding to H69. The higher affinity of the E. coli H69 for neomycin B and tobramycin, as compared to paromomycin and streptomycin, indicates differences in the efficacy of the aminoglycosides

    Abstract Background Tuberculosis (TB) is a major health concern in South Africa, where prior to COVID-19 it was associated with more deaths than any other infectious disease. The COVID-19 pandemic disrupted gains made in the global response to TB, having a serious impact on the most vulnerable. COVID-19 and TB are both severe respiratory infections, where infection with one places individuals at increased risk for negative health outcomes for the other. Even after completing TB treatment, TB survivors remain economically vulnerable and continue to be negatively affected by TB. Methods This cross-sectional qualitative study, which was part of a larger longitudinal study in South Africa, explored how TB survivorsā€™ experienced the COVID-19 pandemic and government restrictions. Participants were identified through purposive sampling and were recruited and interviewed at a large public hospital in Gauteng. Data were analyzed thematically, using a constructivist research paradigm and both inductive and deductive codebook development. Results Participants (nā€‰=ā€‰11) were adults (24ā€“74 years of age; more than half male or foreign nationals) who had successfully completed treatment for pulmonary TB in the past two years. Participants were generally found to be physically, socioeconomically, and emotionally vulnerable, with the COVID-19 pandemic exacerbating or causing a recurrence of many of the same stressors they had faced with TB. Coping strategies during COVID similarly mirrored those used during TB diagnosis and treatment, including social support, financial resources, distraction, spirituality, and inner strength. Conclusions Implications and suggestions for future directions include fostering and maintaining a strong network of social support for TB survivors
