Multimodal Learning Through Media: What the Research Says

Foreword This report is the third in a series that addresses " what the research says, " as Education's ethos states that " without data you are just another opinion. " Like its widely quoted predecessor, the " Technology in Schools " report (SchoolsReport.pdf), and the newly introduced " Education and Economic Growth " report intends to provide a grounding in facts that can benefit the entire Education arena, from pre-K–12 to higher education, corporate training and development, and lifelong learning. There is a lot of misinformation circulating about the effectiveness of multimodal learning, some of it seemingly fabricated for convenience. As curriculum designers embrace multimedia and technology wholeheartedly, we considered it important to set the record straight, in the interest of the most effective teaching and learning. As always, your welcome feedback will allow us improve the report, or suggest avenues for future papers. Introduction " A picture is worth a thousand words. " –Author Unknown People have long quoted this statement, often attributing it to an ancient Chinese proverb. Emergent neuroscience and visualization research now reveals glimpses of the science behind the saying. Visuals matter. The rapid advances of technology in literally every field, including tremendously increased the amount of data and information at our fingertips. As we strive to make sense of unimaginably large volumes of data, visualization has become increasingly important. Why? Our brains are wired to process visual input very differently from text, audio, and sound. Recent technological advances through functional Magnetic Resonance Imaging (fMRI) scans confirm a dual coding system through which visuals and text/auditory input are processed in separate channels, presenting the potential for simultaneous augmentation of learning. The bottom line is that students using well-designed combinations of visuals and text learn more than students who only use text. Educators are in constant search for more efficient and effective ways to advance student learning. Thus it is no surprise that educators have been interested in the often-quoted saying that: We remember… 10% of what we read 20% of what we hear 30% of what we see 50% of what we see and hear 70% of what we say 90% of what we say and do Unfortunately, these oft-quoted statistics are unsubstantiated. If most educators stopped to consider the percentages, they would ask serious questions about the citation. They would inquire about the suspicious rounding of the percentages to multiples of ten, and the …
Comparison of Melatonin and Zolpidem for Sleep in an Academic Community Hospital: An Analysis of Patient Perception and Inpatient Outcomes

Hospitalizations can significantly disrupt patient sleep patterns and contribute to insomnia, which places patients at a higher risk of altered mental status as well as other complications. Despite attempts to control environmental factors, deliriogenic medications are often prescribed for the management of hospital-related insomnia. The primary objective of this study is to compare patient-perceived effectiveness of zolpidem versus melatonin in hospitalized patients. All inpatients who received melatonin or zolpidem the previous night as asleep aid and had no acute psychological issues or history of substance abuse were eligible for participation in this single-center, prospective, observational cohort study. The Verran and Snyder-Halpern sleep scale was utilized to evaluate sleep perception in 3 domains: sleep disturbance, effectiveness, and supplementation. A total of 439 patients were screened and 100 patients met study criteria and consented to the study. In the melatonin and zolpidem groups, the estimated adjusted means for the total sleep effectiveness (206.8 mm, 95% confidence interval [CI], 168.7-253.5vs 187.4 mm, 95% CI, 152.8-229.7; P=.513), sleep disturbance(362.1 mm, 95% CI, 310.1-422.7 vs 339.54 mm, 95% CI, 290.8-396.4; P=.573), and sleep supplementation (111.4 mm, 95% CI, 86.3-143.8 vs 120.9 mm, 95% CI, 94.1-155.2; P=.661) domains were not statistically different. Both melatonin and zolpidem were well tolerated with grogginess and headache as the only reported adverse effects. Melatonin demonstrated no significant difference in patient-perceived sleep effectiveness, disturbance, supplementation, or adverse effects when compared to zolpidem.
A Lotus japonicus cytoplasmic kinase connects Nod factor perception by the NFR5 LysM receptor to nodulation

Significance Legume receptors perceive Nod factor signal molecules at the plasma membrane of epidermal cells and initiate a signal transduction process that leads to the development of root nodules that house nitrogen-fixing rhizobia. Nodule organs are formed by reinitiation of cell divisions in already differentiated root cells. Previous genetic screens have identified plant genes involved in nodulation; however, the receptor-triggered relay mechanism activating the developmental program in the nucleus is still unknown. We present a proteomics approach that identified proteins that associate with the Lotus japonicus Nod factor receptor 5 (NFR5), among which the NFR5-interacting cytoplasmic kinase 4 (NiCK4) appears to be an important link between Nod factor perception by NFR5 and nodule organogenesis. The establishment of nitrogen-fixing root nodules in legume–rhizobia symbiosis requires an intricate communication between the host plant and its symbiont. We are, however, limited in our understanding of the symbiosis signaling process. In particular, how membrane-localized receptors of legumes activate signal transduction following perception of rhizobial signaling molecules has mostly remained elusive. To address this, we performed a coimmunoprecipitation-based proteomics screen to identify proteins associated with Nod factor receptor 5 (NFR5) in Lotus japonicus. Out of 51 NFR5-associated proteins, we focused on a receptor-like cytoplasmic kinase (RLCK), which we named NFR5-interacting cytoplasmic kinase 4 (NiCK4). NiCK4 associates with heterologously expressed NFR5 in Nicotiana benthamiana, and directly binds and phosphorylates the cytoplasmic domains of NFR5 and NFR1 in vitro. At the cellular level, Nick4 is coexpressed with Nfr5 in root hairs and nodule cells, and the NiCK4 protein relocates to the nucleus in an NFR5/NFR1-dependent manner upon Nod factor treatment. Phenotyping of retrotransposon insertion mutants revealed that NiCK4 promotes nodule organogenesis. Together, these results suggest that the identified RLCK, NiCK4, acts as a component of the Nod factor signaling pathway downstream of NFR5.
Protein Expression Analysis in Reversible Photobleached Cells of Scenedesmus vacuolatus after High Temperature Stress

We have analyzed protein expression in the bleached small vegetative cells of synchronous Scenedesmus vacuolatus to investigate how unicellular algae lived through stress. These cells were subjected to heat treatment (46.5 °C for 1h in dark condition) and then cultured under continuous illumination for 24 h. Flow cytometry analysis of the chlorophyll autofluorescence intensity of S. vacuolatus cells indicated that heat-treated cells were completely bleached within 24 h of light cultivation. Transmission electron microscopy (TEM) images showed that bleached cells maintained thylakoid membrane structure, but with lower contrast. The bleached cells regained green color after 72 h, along with a recovery in contrast, which indicated a return of photosynthetic ability. Two-dimensional gel electrophoresis (2DE) showed that the protein expression patterns were very difference between control and bleached cells. ATP synthase subunits and glutamine synthetase were down-regulated among the many differences, while some of phototransduction, stress response proteins were up-regulated in bleached cells, elucidating bleached cells can undergo changes in their biochemical activity, and activate some stress response proteins to survive the heat stress and then revive. In addition, small heat shock proteins (HSPs), but not HSP40 and HSP70 family proteins, protected the bleaching cells.
Formation of semi‐enveloped particles as a unique feature of a hepatitis B virus PreS1 deletion mutant

Naturally occurring variants with deletions or mutations in the C‐terminal PreS1 domain from hepatitis B virus (HBV) chronically infected patients have been shown to promote HBsAg retention, inhibit HBsAg secretion and change the extracellular appearance of PreS1‐containing HBV particles (filaments and virions).
The effects of prosody on sentence comprehension: evidence from a neurotypical control group and seven cases of chronic stroke

ABSTRACT Both prosody and sentence structure (e.g., canonical versus non-canonical) affect sentence comprehension. However, few previous studies have examined a possible interaction between prosody and sentence structure. In adult controls we found a significant interaction: typical sentence prosody, versus list prosody, facilitated comprehension of only some sentence structures. In seven stroke patients, impaired attentional control was related to impaired comprehension with sentence prosody but not list prosody; impaired working memory was related to impaired comprehension with list prosody, but not sentence prosody. Thus, non-canonical sentence comprehension impairments in stroke patients may be modulated by prosody, based on a patient’s cognitive abilities.
Correlation Between HMGB1 and TLR4 Expression in Sinonasal Mucosa in Patients With Chronic Rhinosinusitis

Objectives: Chronic rhinosinusitis (CRS) is one of the most common inflammations in the upper airway. Despite the wide prevalence of CRS, the pathogenesis of this disease is poorly understood. Several components of the innate immune system may play a significant role in CRS, including Toll-like receptor 4 (TLR4), TLR9, and high-mobility group box 1 protein (HMGB1). This study was conducted to determine the expression of TLR4, TLR9, HMGB1, and pNFκ-B p65 in paraffin-embedded blocks of patients with CRS with nasal polyps compared with those of the control group. Methods: Twenty-six formalin-fixed, paraffin-embedded samples from patients with confirmed CRS and 26 patients undergoing septoplasty due to anatomic variations and no other inflammatory nasal diseases as the control group were assessed. Expression patterns of HMGB1, TLR9, TLR4, and pNFκ-B p65 genes were examined using real-time quantitative reverse transcription polymerase chain reaction (Real-Time qRT-PCR). Statistical analyses were performed with SPSS and analyzed using unpaired 2-tailed t tests or 1-way analysis of variance. Results: Real-time PCR showed that the expression level of HMGB1 messenger RNA was significantly increased in the tissues of patients with CRS compared with controls (P < .05). The other 3 genes were also upregulated in the patients, but were not significant compared with control. Analysis of the Pearson correlation coefficient (r) revealed a significant positive correlation between HMGB1 and TLR4 (r = 0.79, P < .05) in patients and negative correlation between TLR4 and NfκB in the control group (r = 0.94; P < .05). Conclusions: Both HMGB1 and TLR4 are increased in the paranasal sinus mucosa of patients with CRS. These results suggest a possible contribution of HMGB1 and its internal receptor (TLR4) in the pathophysiology of CRS.
Hyperbilirubinemia as a predictor of severity of acute appendicitis

Objective This study aimed to investigate the clinical significance of preoperative hyperbilirubinemia in Japanese patients and to assess its clinical potential as a predictor of the severity of acute appendicitis. Methods We studied 318 patients with appendicitis who underwent appendectomy between July 2010 and June 2017. We analyzed preoperative data including age, sex, white blood cell count, C-reactive protein (CRP) level, fever, peritoneal irritation signs, and serum total bilirubin level as potential risk factors for complicated (perforated or gangrenous) appendicitis, using multivariate analysis. Results Complicated appendicitis was significantly more frequent in patients with hyperbilirubinemia (>1.1 mg/dL), high CRP level (>0.5 mg/dL), positive peritoneal irritation signs, and fever (>37.3°C). Multivariate analysis revealed older age (>64 years), hyperbilirubinemia, high CRP level, and fever (odds ratios 3.36, 1.75, 7.61, and 2.43, respectively) as risk factors for complicated appendicitis. Multivariate analysis also identified hyperbilirubinemia, high CRP level, and fever (odds ratios 1.99, 5.90, and 2.72, respectively) as risk factors for complicated appendicitis among patients aged <65 years. Conclusions Hyperbilirubinemia, high CRP level, and fever may be useful predictors of the severity of acute appendicitis, with hyperbilirubinemia being especially useful among patients aged <65 years.
Cognitive fusion and depressive symptoms in women with chronic pain: a longitudinal growth curve modelling study over 12-months.

This study aims 1) to explore individual differences in women with chronic pain (CP) in regard to pain intensity, functional impairment, cognitive fusion and depressive symptoms, and 2) to longitudinally test whether cognitive fusion is a significant predictor of depression symptoms, while controlling for pain intensity and functional impairment, over a 12-month period. This study follows a longitudinal design, and was conducted in a sample of 86 women with CP who responded to an online battery of questionnaires in three equally-spaced assessment moments. In order to explore the growth trajectory of variables of interest, latent growth curve models were examined. Also, correlation analyses were conducted between demographic and illness-related variables and depressive symptoms, as well as between all variables in all assessment moments. Cognitive fusion and functional impairment (but not pain intensity) were significantly associated with baseline levels of depressive symptoms. Cognitive fusion significantly predicted the growth trajectory of depressive symptoms, while pain intensity and functional impairment did not. No demographic (age, marital status, education, socio-economic) nor illness-related variables (number of CP diagnoses, duration of CP, taking medication) were associated with depressive symptoms at any point. These results suggest that the trajectory of depressive symptoms in women with CP is not predicted by the intensity of pain nor pain-related functional impairment, but rather by the tendency to get entangled with internal experiences (e.g. thoughts, emotions, physical sensations) that may or may not be related to pain-specific contents. Clinical implications are discussed.
Evaluating the relationship between binge drinking rates and a replicable measure of U.S. state alcohol policy environments

Excessive alcohol consumption contributes significantly to premature mortality, injuries and morbidity, and a range of U.S. state policies have been shown to reduce these behaviors. Monitoring state alcohol policy environments is essential, but methodologically challenging given that new laws may be passed (or repealed) each year, resulting in considerable variation across states. Existing measures have not been made public or have only a single year available. We develop a new replicable measure, the state alcohol policy score, for each state and year 2004–2009, that captures the essential features of a state’s evidence-based alcohol policies. We evaluate its similarity to two existing alcohol policy measures and validate it by replicating findings from a previous study that used one of those measures to assess its relationship with several binge drinking outcomes. Estimates of the association between one-year lagged state alcohol policy scores and state binge drinking outcomes, obtained from the 2005–2010 Behavioral Risk Factor Surveillance System surveys (n = 440,951, 2010), were produced using Generalized Linear Models that controlled for state and individual-level co-variates, with fixed effects for year and region. We find a 10-percentage point increase in the state alcohol policy score was associated with a 9% lower odds of binge drinking (aOR = 0.91, 95% CI 0.89, 0.92; N = 1,992,086), a result consistent for men, women and for most age and race subgroups. We find that gender gaps in binge drinking behaviors narrowed in states with higher state alcohol policy scores. These results were nearly identical to those found in other studies using different scores obtained with the aid of expert opinions. We conclude that the score developed here is a valid measure that can be readily updated for monitoring and evaluating the variation and impact of state alcohol policies and make available our state scores for the years of the study.
Vibrio cholerae filamentation promotes chitin surface attachment at the expense of competition in biofilms

Significance The human pathogen Vibrio cholerae, when not inside of a host, grows in cell clusters (biofilms) on pieces of detritus in aquatic environments. Here we discovered that some isolates of V. cholerae can change their shape from small comma-shaped cells to long filaments in seawater. This altered cell shape allows cells to make new types of biofilms, and provides an advantage in quickly colonizing particles in seawater, at the expense of longer-term competitive ability. The filamentous cell-shape strategy is particularly effective at competing in environments with quick turnover of chitin particles. This result showcases how bacterial cell shape can be coupled to environmental success during surface occupation, competition within biofilms, and dispersal to new resource patches. Collective behavior in spatially structured groups, or biofilms, is the norm among microbes in their natural environments. Though biofilm formation has been studied for decades, tracing the mechanistic and ecological links between individual cell morphologies and the emergent features of cell groups is still in its infancy. Here we use single-cell–resolution confocal microscopy to explore biofilms of the human pathogen Vibrio cholerae in conditions mimicking its marine habitat. Prior reports have noted the occurrence of cellular filamentation in V. cholerae, with variable propensity to filament among both toxigenic and nontoxigenic strains. Using a filamenting strain of V. cholerae O139, we show that cells with this morphotype gain a profound competitive advantage in colonizing and spreading on particles of chitin, the material many marine Vibrio species depend on for growth in seawater. Furthermore, filamentous cells can produce biofilms that are independent of primary secreted components of the V. cholerae biofilm matrix; instead, filamentous biofilm architectural strength appears to derive at least in part from the entangled mesh of cells themselves. The advantage gained by filamentous cells in early chitin colonization and growth is countered in long-term competition experiments with matrix-secreting V. cholerae variants, whose densely packed biofilm structures displace competitors from surfaces. Overall, our results reveal an alternative mode of biofilm architecture that is dependent on filamentous cell morphology and advantageous in environments with rapid chitin particle turnover. This insight provides an environmentally relevant example of how cell morphology can impact bacterial fitness.
An examination of cultural-linguistic influences on PPVT-4 performance in African American and Hispanic preschoolers from low-income communities

ABSTRACT In this study, we examined potential influences of cultural and linguistic background on PPVT-4 performance in a community sample of preschool-age children from low-SES households. We did this by evaluating PPVT-4 item-level performance across African American and Hispanic children from low-income families. We compared PPVT-4 item-level performance for 332 Hispanic and African American children (Mage = 48 months) using Wald chi-square tests of independence. There were clinically significant differences in accuracy on 14 PPVT-4 test items with most favouring the African American group. We then looked at the relationship between African American English use and PPVT-4 scores for a subset of 113 African American children (Mage = 49.9 months). A correlational analysis with PPVT-4 standard scores and a dialect density measure (DDM) in narratives revealed no association between these measures. We concluded that there were potential cultural-linguistic biases in PPVT-4 items that were not explained by income alone for the young Hispanic children.
The energetic basis for hydroxyapatite mineralization by amelogenin variants provides insights into the origin of amelogenesis imperfecta

Significance Protein binding is important to many biological processes such as biomineralization, cell signaling, and enzyme interactions. We found that protein binding is key in explaining how single amino acid changes in amelogenin can lead to adverse effects on the biomineralization of hydroxyapatite (HAP) in tooth enamel. A normal amount of protein adsorption resulted in HAP formation and the enzymatic removal of protein from HAP surfaces by MMP20 for the wild-type amelogenin, rpM179. Excessive protein binding, however, inhibited HAP formation and slowed the removal of protein by MMP20 for T21I, P41T, and P71T single amino acid variants. Excessive protein binding may be an important factor in explaining how single amino acid variants cause the amelogenesis imperfecta phenotype in vivo. Small variations in the primary amino acid sequence of extracellular matrix proteins can have profound effects on the biomineralization of hard tissues. For example, a change in one amino acid within the amelogenin protein can lead to drastic changes in enamel phenotype, resulting in amelogenesis imperfecta, enamel that is defective and easily damaged. Despite the importance of these undesirable phenotypes, there is very little understanding of how single amino acid variation in amelogenins can lead to malformed enamel. Here, we aim to develop a thermodynamic understanding of how protein variants can affect steps of the biomineralization process. High-resolution, in situ atomic force microscopy (AFM) showed that altering one amino acid within the murine amelogenin sequence (natural variants T21 and P41T, and experimental variant P71T) resulted in an increase in the quantity of protein adsorbed onto hydroxyapatite (HAP) and the formation of multiple protein layers. Quantitative analysis of the equilibrium adsorbate amounts revealed that the protein variants had higher oligomer–oligomer binding energies. MMP20 enzyme degradation and HAP mineralization studies showed that the amino acid variants slowed the degradation of amelogenin by MMP20 and inhibited the growth and phase transformation of HAP. We propose that the protein variants cause malformed enamel because they bind excessively to HAP and disrupt the normal HAP growth and enzymatic degradation processes. The in situ methods applied to determine the energetics of molecular level processes are powerful tools toward understanding the mechanisms of biomineralization.
