17. Increase in Social Media Use to Support Increased Meal Preparation by College Students during the COVID-19 Experience

Background The COVID-19 pandemic has resulted in higher education institutions transitioning to online course delivery and limiting on-campus activities. With decreasing access to campus food service and restaurants, college students with limited cooking experience are now reliant on home-prepared meals. Purpose The purpose of this study was to explore cooking skills and social media use for meal preparation in college students during the COVID-19 experience. Method This cross-sectional descriptive study utilized an online survey with U.S. college students early in the Covid-19 pandemic. The subset of questionnaire items used for this study included demographic, social media use, and cooking and shopping behaviors items. Results Nearly 30% of the college student respondents (N=282) self-identified as the primary person responsible for preparing meals in their homes, while 40% had shared responsibility. Over 50% of the respondents reported increasing meal preparation activities during the quarantine. At the same time, 64% increased their use of social media for researching food preparation techniques and recipe ideas. Sixty-two percent described having “good” grocery shopping skills, while only 51% described their cooking skills as “good”. Conclusions There is an identified need for providing food preparation and shopping skills education to support college students’ ability to manage and adapt during disruptive times

Multiplexed five-color molecular imaging of cancer cells and tumor tissues with carbon nanotube Raman tags in the near-infrared

Single-walled carbon nanotubes (SWNTs) with five different C13/C12 isotope compositions and well-separated Raman peaks have been synthesized and conjugated to five targeting ligands in order to impart molecular specificity. Multiplexed Raman imaging of live cells has been carried out by highly specific staining of cells with a five-color mixture of SWNTs. Ex vivo multiplexed Raman imaging of tumor samples uncovers a surprising up-regulation of epidermal growth factor receptor (EGFR) on LS174T colon cancer cells from cell culture to in vivo tumor growth. This is the first time five-color multiplexed molecular imaging has been performed in the near-infrared (NIR) region under a single laser excitation. Near zero interfering background of imaging is achieved due to the sharp Raman peaks unique to nanotubes over the low, smooth autofluorescence background of biological species.Comment: Published in Nano Researc

Luminescent supramolecular silver(I) coordination complexes of pyridyl-substituted phosphinites, phosphonites and amines.

Includes bibliographical references (p. 273-283).Interest in the design and synthesis of supramolecular metal-organic coordination polymers has increased exponentially in the last decade. This attraction comes along with advances in crystallographic instrumentation that has made the collection and processing of crystal data sets faster and more automated than ever. As a result, our understanding of the intra- and intermolecular forces that exist within the confines of the crystalline lattice is at a historic high. In this work we use several new bi- and tridentate pyridyl-substituted phosphinite ligands as well as a series of isomeric aminomethylpyridines to construct discrete, one-, two, and three-dimensional metal-organic coordination architectures with salts of the silver(I) cation. These complexes were then analyzed and discussed in terms of the variables (metal/ligand ratio, anion, temperature, solvent) and forces (donor-metal bonding, hydrogen-bonding, π-stacking, dispersion forces) that cause the structural motifs that are observed. The luminescence of these complexes was also studied and was seen to be variable with changes in structure and metal environment.by Rodney P. Feazell.Ph.D

The Hospital Board at Risk and the Need to Restructure the Relationship with the Medical Staff: Bylaws, Peer Review and Related Solutions

This article argues that the current structure of the hospital governing board and medical staff relationship does not support and promote quality and patient-centered care. The fundamental flaw in the current structure is the interdependent, yet independent and discordant relationships between hospital governing boards and medical staffs. These relationships are described as cultures and fit into three types of silos : organizational (the structural silo ); professional (the professional silo , including the culture of blame ); and the fragmented quality information silo (the informational silo ). While case law, statutory requirements and regulatory expectations clearly state that governing boards are ultimately responsible for quality of patient care, governing boards delegate these functions to medical staff without having sufficient information to measure and monitor quality. As a result, problems manifest because of these failures of oversight and compliance. Dramatic lapses in quality occur due to overuse, underuse, and misuse of healthcare services. Furthermore, the challenges and opportunities from improved quality and patient safety, as a strategic business driver, cannot be seized until the underlying structural flaws are understood and addressed. This article proposes that solutions become apparent when the various health care constituencies are educated about these cultural impacts and when multidisciplinary bodies, with board leadership and direct authority, integrate and consider quality information

Crystal structure of 2,6-bis-hydrazinopyridine dihydrate, its tosylate salt and 2,6-bis-(3,5-di-tert-butylpyrazolyl)pyridine

The crystal structures of the new compounds 2,6-bis-hydrazinopyridine dihydrate (2), its tosylate salt (3) and 2,6-bis-(3,5-di-tert-butylpyrazolyl) pyridine (4) were obtained by single-crystal X-ray diffraction. Crystallization of 2 occurs in the centrosymmetric monoclinic space group P21/c (No. 14) with a = 9.6218(18), b = 6.7331(12), c = 13.489(3); and β = 109.292(8)° and Z = 4. Crystallization of 3 occurs in the centrosymmetric monoclinic space group P21/c (No. 14) with a = 26.530(3), b = 16.6456(18), c = 9.9458(10) and β = 96.828(5) and Z = 8, while 4 crystallizes in P21/n (No. 14) with a = 15.0555(10), b = 10.4496(7), c = 16.9599(12) and β = 101.480(4) and Z = 4. These are the only structures for any bis-hydrazinopyridines reported to date. Details of the synthesis, structures and spectroscopic results are presented and discussed. © 2005 Springer Science+Business Media, Inc
